Description

  The present invention relates to a holder for fixing, for example, a blood reservoir tank constituting a part of a heart-lung machine.

  In general, an oxygenator or an auxiliary circulator has an extracorporeal circuit including a blood reverser tank that temporarily stores venous blood in addition to a blood circulation pump and an artificial lung.

  Each member of the extracorporeal circuit needs to be fixed in a highly visible state in order to ensure monitoring during the operation. For example, Patent Literature 1 discloses an extracorporeal circulation device holder for fixing each member of the extracorporeal circuit to a support member that extends vertically upward from a gantry.

  The holder of Patent Document 1 includes a horizontal arm member that is fixed to a support member and extends in the horizontal direction, and a vertical arm member that extends vertically downward from the horizontal arm member. A bar for holding each member of the extracorporeal circuit is inserted and fixed to the vertical arm member in the horizontal direction. The height of each member of the extracorporeal circuit can be adjusted by changing the insertion position of the bar with respect to the vertical arm member, and the extracorporeal circuit can be adjusted by changing the amount of insertion of the bar with respect to the vertical arm member. It is possible to adjust the position of each member in the horizontal direction.

  By the way, during extracorporeal circulation, it is necessary to adjust the blood flow while paying close attention to the blood level of the blood reservoir tank, so that it is possible to accurately grasp the blood level as well as ensuring good visibility. So that the blood reservoir tank should be fixed.

  The blood reservoir tank is engraved with a scale indicating the stored blood volume. By reading this scale, the stored blood volume is grasped, but if the blood reservoir tank is tilted and fixed, the scale will The blood level is not shown, and the blood level cannot be accurately grasped.

  In particular, when extracorporeal circulation is performed in a pediatric patient, it is more important to accurately grasp the blood level in the blood reservoir tank because the absolute blood volume is smaller than that in an adult.

  Assuming the case where the blood reservoir tank is fixed using the holder of Patent Document 1, with this holder, only the height adjustment and horizontal position adjustment of each member of the extracorporeal circulation circuit can be performed. If the support member of the gantry is tilted with respect to the vertical line due to, for example, the blood reservoir tank is tilted and fixed from the normal fixed state, and as a result, it is difficult to accurately grasp the blood level described above. There are cases. Further, in the holder of Patent Document 1, due to manufacturing errors, for example, when the horizontal arm member is inclined with respect to the horizontal line or when the vertical arm member is inclined with respect to the vertical line, the blood reservoir tank is similarly The blood level may not be accurately grasped.

  The present invention has been made in view of such a point, and the object thereof is to fix the blood reservoir tank so that the blood level can be accurately grasped even when the support member is inclined. There is to do.

  In order to achieve the above object, in the present invention, the holding member for holding the blood reservoir tank can be rotated and tilted.

A first invention is a blood reservoir tank holder for fixing a blood reservoir tank to a support member,
An arm member attached to the support member;
A holding member for holding the blood reservoir tank;
A connecting portion for connecting the arm member and the holding member;
The connecting portion connects the holding member to a portion of the arm member to which the holding member is connected so as to be rotatable around the center line of the portion and to be tiltable with respect to the center line ,
The connecting portion includes a movable member and a clamp mechanism for clamping the movable member, the movable member is fixed to one member of the arm member and the holding member, and the clamp mechanism is It is fixed to the other member of the arm member and the holding member,

The member to which the clamp mechanism is fixed is formed with a stopper portion insertion hole into which the stopper portion is inserted and a columnar portion insertion hole into which the columnar portion is inserted,
The stopper portion sets a rotation range and a tilt range of the holding member by engaging with a peripheral portion of the stopper portion insertion hole,
When said stopper is engaged with the peripheral edge of the stopper portion insertion hole, the columnar portion is characterized in Rukoto disposed away from the periphery of the columnar portion insertion hole.

  According to this configuration, the holding member that holds the blood reservoir tank can be rotated around the center line with respect to the arm member, and can be tilted with respect to the center line. This makes it possible to correct the inclination of the blood reservoir tank.

Further, for example, advance to secure the movable member in the holding member, when fixing the clamp mechanism to the arm member, by releasing the clamping of the clamping mechanism, since the movable member becomes free to move, the holding member The arm member can be easily rotated around its center line and tilted with respect to the center line. On the other hand, when the movable member is clamped by the clamp mechanism, the movement of the movable member is prevented, so that the holding member can be fixed at an arbitrary position. The same applies when the movable member is fixed to the arm member and the clamp mechanism is fixed to the holding member.

In addition , when the holding member is rotated or tilted, the holding member is unexpectedly rotated or tilted unexpectedly because the stopper portion of the movable member is engaged with the peripheral portion of the insertion hole. Can be suppressed.

  According to the first invention, the holding member that holds the blood reservoir tank can be rotated around the center line with respect to the arm member and can be tilted with respect to the center line. It can be corrected. Thereby, even when the support member is inclined, the blood reservoir tank can be fixed so that the blood level can be accurately grasped.

Further , since the movable member of the connecting portion is fixed to one of the arm member and the holding member, and the clamp mechanism for clamping the movable member is fixed to the other member, the holding member can be rotated by operating the clamp mechanism. In addition, the tiltable state and the fixed state can be easily switched, and the operability can be improved.

Further , since at least one of the rotation range and the tilting range of the holding member can be set by the stopper portion, it is possible to prevent the holding member from rotating unexpectedly or tilting. The inclination of the blood reservoir tank can be corrected safely and easily.

The attachment plate portion 51c is fastened and fixed to the proximal end portion of the main body portion 31 of the holding member 30 by a fastening member (bolt, screw or the like) inserted through the attachment hole 51d. Therefore, the spherical member 51 is integrated with the holding member 30.

  The clamp mechanism 52 includes left and right clamp blocks 53 and 54, left and right plate members 55 and 56, a clamp lever 57 (shown in FIG. 8), and a housing 60. The left clamp block 53 has a rectangular parallelepiped shape made of an elastic member such as rubber. On the right side surface of the left clamp block 53, a concave portion 53a is formed in which the left part of the outer surface of the spherical member 51 is fitted. The right clamp block 54 is configured in the same manner as the left clamp block 53, and a concave portion 54 a is formed on the left side surface of the right clamp block 54 so that the right part of the outer surface of the spherical member 51 fits. . The left side plate member 55 is formed so as to extend along the left side surface of the left clamp block 53 and is disposed so as to be in contact with the left side surface, and is a member harder than the left clamp block 53, for example, a stainless plate. Etc. The right side plate member 56 is configured in the same manner as the left side plate member 55, and is disposed on the right side surface of the right clamp block 54.

  The housing 60 accommodates the spherical member 51, the left and right clamp blocks 53 and 54, and the left and right plate members 55 and 56. The housing 60 is composed of a left side member 61 and a right side member 62 that are divided into left and right at the center in the left and right direction. The housing 60 is fixed to the block 13 of the arm member 10.

  The left member 61 is formed with a left receiving recess 61 a for receiving the left clamp block 53 and the left plate member 55. A left upper cutout 61 b is formed at the upper right edge of the left member 61. A left lower notch 61c is formed at the right edge of the left member 61 on the holding member 30 side. Further, as indicated by phantom lines in FIG. 8, a left screw hole 61 d penetrating in the left-right direction is formed in the vicinity of the approximate center of the left wall portion of the left member 61.

  The right member 62 is formed in the same manner as the left member 61, and is formed with a right receiving recess 62a for receiving the right clamp block 54 and the right plate member 56, as shown in phantom lines in FIG. As shown in FIG. 10, a right upper notch 62 b is formed at the upper left edge of the right member 62. A right lower notch 62c is formed at the left edge of the right member 62 on the holding member 30 side. A right screw hole 62d penetrating in the left-right direction is formed in the vicinity of the approximate center of the right wall portion of the right member 62.

  The left member 61 and the right member 62 can be integrated using a fastening member (not shown) in a state where the left member 61 and the right member 62 are combined. In the integrated state, the spherical member 51 is sandwiched between the left clamp block 53 and the right clamp block 54 from the left-right direction and is held at the approximate center in the left-right direction.

  As shown in FIG. 8, the clamp lever 57 has a screw shaft portion 57 a that is screwed into the right screw hole 62 d of the housing 60. The screw shaft portion 57a extends substantially horizontally. A lever main body 57b is fixed to the proximal end portion of the screw shaft portion 57a. The tip end surface 57 c of the screw shaft portion 57 a is in contact with the right side surface of the right side plate member 56.

  When the clamp lever 57 is rotated in a direction in which the screw shaft portion 57a is screwed into the right screw hole 62d of the housing 60, the front end surface 57c of the screw shaft portion 57a pushes the right plate member 56 to the left side. Since 55 is fixed in the housing 60, the spherical member 51 is clamped between the left and right clamp blocks 53 and 54, and does not move relative to the housing 60. On the other hand, when the clamp lever 57 is rotated in the direction opposite to the above direction, the tip end surface 57c of the screw shaft portion 57a moves to the right side, the clamped state of the spherical member 51 is released, and the movement with respect to the housing 60 is allowed. Is done.

  Further, in a state where the left side member 61 and the right side member 62 are integrated, as shown in FIG. 11, the open sides of the left upper notch 61b of the left member 61 and the right upper notch 62b of the right member 62 are aligned. Then, the stopper portion insertion hole 63 into which the stopper portion 51a is inserted is formed, and the open sides of the left lower notch portion 61c of the left member 61 and the right lower notch portion 62c of the right member 62 are matched, A cylindrical portion insertion hole 64 into which the cylindrical portion 51b is inserted is formed. The shape of the stopper portion insertion hole 63 can be set by the shape of the left upper cutout portion 61b and the right upper cutout portion 62b, and the shape of the cylindrical portion insertion hole 64 is the left lower cutout portion 61c and the right lower cutout portion 62c. And can be set by the shape.

  The cylindrical portion insertion hole 64 is a long hole that is long in the vertical direction. The dimension in the major axis direction (vertical direction) of the cylindrical part insertion hole 64 is set longer than the outer diameter of the cylindrical part 51 b of the spherical member 51 by a predetermined length or more. The dimension in the minor axis direction (left-right direction) of the cylindrical part insertion hole 64 is set to be substantially the same as the outer diameter of the cylindrical part 51b, but the outer peripheral surface of the cylindrical part 51b and the inner peripheral surface of the cylindrical part insertion hole 64 are There is a slight gap between the two so that there is no strong interference. Accordingly, the cylindrical portion 51b does not move in the left-right direction within the cylindrical portion insertion hole 64, but is movable in the vertical direction.

  The stopper insertion hole 63 is a long hole that is long in the depth direction of the housing 60. The dimension of the stopper part insertion hole 63 in the major axis direction (depth direction) is set to be longer than the outer diameter of the stopper part 51a by a predetermined length or more. The dimension of the stopper portion insertion hole 63 in the minor diameter direction (left and right direction) is also set longer than the outer diameter of the stopper portion 51a. Accordingly, the stopper portion 51a is movable in the depth direction and the left-right direction in the stopper portion insertion hole 63.

  Since the stopper portion insertion hole 63 and the columnar portion insertion hole 64 are formed as described above, the spherical member 51 is rotatable inside the housing 60 in a state where the clamp is released. Thereby, the holding member 30 to which the spherical member 51 is fixed is allowed to move with respect to the block 13 of the arm member 10. As shown by arrows A and B in FIGS. 4 and 5, the movement direction of the holding member 30 is a direction in which the arm member 10 tilts up and down with respect to the center line X of the block 13 (tilt direction), The direction of rotation around the center line X (rotation direction) as indicated by arrows C and D in FIG. That is, by providing and clamping the spherical member 51 in the connection part 50, it can be set as a ball joint type connection structure, and tilting and rotation can be performed steplessly.

  The movement in the tilting direction is such that the stopper portion 51 a of the spherical member 51 moves in the depth direction in the stopper portion insertion hole 63 of the housing 60, and the cylindrical portion 51 b of the spherical member 51 is in the cylindrical portion insertion hole 64 of the housing 60. This is realized by moving up and down. At this time, the cylindrical portion 51b of the spherical member 51 moves only in the vertical direction within the cylindrical portion insertion hole 64 and does not move in the horizontal direction. Therefore, the movement of the holding member 30 does not become unstable, and the vertical direction Can only be tilted. That is, the cylindrical portion 51b can be guided in the vertical direction by the cylindrical portion insertion hole 64.

  In addition, the stopper portion 51a comes into contact with and engages with the front edge portion of the peripheral edge portion of the stopper portion insertion hole 63, so that the upward tilting range of the holding member 30 is set. The downward tilting range is set by the portion 51a contacting and engaging with the rear edge of the stopper portion insertion hole 63. When the stopper portion 51a is engaged with the front edge portion or the rear edge portion of the stopper portion insertion hole 63, the column portion 51b is not engaged with the upper edge portion or the lower edge portion of the column portion insertion hole 64. It has become. In this embodiment, the tilt angle of the holding member 30 is set to 11.5 degrees upward with respect to the center line X. Further, the downward tilt angle is set in the same manner. The tilt angle is not limited to the above value, and may be set to another value.

  The movement of the holding member 30 in the rotation direction is that the stopper portion 51 a of the spherical member 51 moves in the left-right direction in the stopper portion insertion hole 63 of the housing 60, and the column portion 51 b of the spherical member 51 is the column of the housing 60. This is realized by rotating around the center line of the cylindrical part 51b in the part insertion hole 64.

  In addition, the stopper portion 51a comes into contact with and engages with the right edge portion of the peripheral edge portion of the stopper portion insertion hole 63, so that the rotation range to the right side of the holding member 30 is set. When the part 51a contacts and engages with the left edge part of the stopper part insertion hole 63, the rotation range to the left side is set. In this embodiment, the rotation angle of the holding member 30 is set to 9 degrees to the right around the center line X. Further, the rotation angle to the left side is set similarly. The rotation angle is not limited to the above value, and may be set to another value.

  Next, how to use the blood reservoir tank holder 1 configured as described above will be described. First, the blood reservoir tank holder 1 is attached to the pole P. At this time, the pipe clamp lever 14 is turned up and down to clamp the pipe P with the arm head 11a.

  With the blood reservoir tank holder 1 attached to the pole P, the height of the holding member 30 can be adjusted and the position around the shaft 12 can be adjusted by operating the upper shaft clamp lever 15 and the lower shaft clamp lever 16. Can also be done.

  In a state where the blood reservoir tank T is held by the holding member 30, the inclination of the blood reservoir tank T is corrected so that the inclination of the blood reservoir tank T is 0, that is, not inclined with respect to the vertical line. When correcting the inclination, first, the clamp lever 57 is rotated in the loosening direction. Then, the clamped state of the spherical member 51 is released, and the spherical member 51 can move between the left clamp block 53 and the right clamp block 54.

  In this state, the holding member 30 is tilted up and down or rotated left and right to make the tilt of the blood reservoir tank T zero. When tilting the holding member 30 up and down, the cylindrical portion 51b of the spherical member 51 can be guided in the vertical direction by the cylindrical portion insertion hole 64 of the housing 60, so that it does not unexpectedly tilt in the left and right direction. Workability is good.

  Further, when the holding member 30 is tilted, it is possible to prevent the holding member 30 from tilting unexpectedly greatly because the stopper portion 51a engages with the peripheral edge portion of the stopper portion insertion hole 63 of the housing 60. . Even when the holding member 30 is rotated, the stopper portion 51a engages with the peripheral edge portion of the stopper portion insertion hole 63 of the housing 60, so that it is possible to prevent the holding member 30 from rotating unexpectedly greatly. It is.

  When the inclination of the blood reservoir tank T becomes zero, the clamp lever 57 is rotated in a direction in which the screw shaft portion 57 a is screwed into the right screw hole 62 d of the housing 60. Then, the spherical member 51 is clamped by the left clamp block 53 and the right clamp block 54, the spherical member 51 stops moving with respect to the housing 60, and the blood reservoir tank T is fixed to the pole P.

  As described above, according to the blood reservoir tank holder 1 according to this embodiment, the holding member 30 that holds the blood reservoir tank T is rotated around the center line X with respect to the arm member 10, and It can be tilted with respect to the center line X. Thereby, the inclination of the blood reservoir tank T can be corrected. Therefore, the blood reservoir tank T can be fixed so that the blood level can be accurately grasped even when the pole P is inclined.

  Further, the spherical member 51 of the connecting portion 50 is fixed to the holding member 30, and a clamp mechanism 52 that clamps the spherical member 51 is fixed to the arm member 10. Thereby, by operating the clamp mechanism 52, the state in which the holding member 30 can be rotated and tilted and the fixed state of the holding member 30 can be easily switched, and the operability can be improved.

  In addition, since the rotation range and tilt range of the holding member 30 can be set by the stopper portion 51a, the holding member 30 can be prevented from rotating or tilting unexpectedly. The inclination of the blood reservoir tank T can be corrected safely and easily.

  In the above-described embodiment, the stopper portion 51a of the spherical member 51 of the connecting portion 50 protrudes upward. However, the present invention is not limited to this, and it protrudes downward as in the modification shown in FIG. May be. In this case, the stopper insertion hole 63 of the housing 60 is formed in the lower wall portion of the housing 60. In this modification, it is not necessary to provide the stopper portion insertion hole in the upper wall portion of the housing 60. Therefore, it is possible to suppress dust and the like from entering the housing 60, and the spherical member 51 can be used over a long period of time. Can move smoothly.

  Moreover, in the said embodiment, although the spherical member 51 of the connection part 50 is fixed to the holding member 30, and the clamp mechanism 52 is fixed to the block 13 of the arm member 10, it is not restricted to this, The spherical member 51 may be fixed to the block 13 of the arm member 10 and the clamp mechanism 52 may be fixed to the holding member 30.

  In the above embodiment, the range of both tilting and rotation of the holding member 30 is set by the stopper portion 51a of the spherical member 51 of the connecting portion 50 and the stopper portion insertion hole 63 of the housing 60. However, the present invention is not limited to this, and only the tilting range of the holding member 30 and only the rotation range of the holding member 30 may be set by a method such as changing the shape of the stopper portion insertion hole 63.

  Moreover, in the said embodiment, although the arm member 10 is divided | segmented into the three members of the horizontal arm 11, the shaft 12, and the block 13, it is not restricted to this, The arm member 10 may be an integrally molded product.

  Further, the clamp lever 57 may be screwed into the left screw hole 61 d of the housing 60. Also in this case, the spherical member 51 can be switched between the clamped state and the clamp-released state by the clamp lever 57.

  In the above embodiment, the spherical member 51 is made of a hard material, and the left and right clamp blocks 53 and 54 are made of an elastic material. On the contrary, the spherical member 51 is made of an elastic material. The left and right clamp blocks 53 and 54 may be made of a hard material. In this case, the left side plate member 55 and the right side plate member 56 can be omitted.

  The above-described embodiment is merely an example in all respects and should not be interpreted in a limited manner. Further, all modifications and changes belonging to the equivalent scope of the claims are within the scope of the present invention.
