In the case of the figure, it is sufficient to further bend the outer peripheral frame 1c and break the breakage thin wall 6a, and the first part 2 and the second part 3 are separated as shown in the figure c. This allows the patient to retreat with the connecting end C' still attached with the separated second part 3 attached.

In addition, in the case of FIG. 2, the patient does not need to perform the above-mentioned bending operation, and the cutter 4 can be moved to the thin wall 6 for cutting by simply grasping the previous stage.
Since b is cut, the first part 2 and the second part 3 can be separated more quickly.

Next, the second invention of the present application will be explained using the embodiment shown in FIG. 3. As in the case of FIG. 1 and FIG. A first part 2 having a first holding part 2d, and a second part 3 having a second flow stop part 3b and a second holding part 3d.
However, because the outer peripheral frame 1c is formed in a U-shape with an opening toward one side, the terminal parts 1a and 1b are arranged one above the other, and the terminal A straight upper gripping portion 1d and a lower gripping portion 1e are formed facing toward the portions 1a and 1b,
The second part 3 is placed between the upper and lower handle parts 1d and 1e.
A press-down receiving part 3e is provided in the second part 3 so that the bottom surface of the upper handle part 1d is pressed when the two handle parts are tightened. 1d' and 1e' indicate anti-slip portions provided on the upper and lower handle portions 1d and 1e.

Further, the second part 3 is connected to the lower handle part 1e of the outer circumferential frame 1e via a separating part 6, which is connected to the upper handle part 1d, as in the case of FIG. The fixing means for the cutter 4 includes a protrusion 4e protruding from a mounting arm 4d protruding from the outer peripheral frame 1c, the protrusion 4e being fitted into a mounting hole of the cutter 4, and heat caulking of the protrusion 4e. I have to.

Therefore, in the case of Fig. 3, the upper and lower handle parts 1
By tightening the grips d and 1e, the first flow stop part 2b of the first part 2 squeezes the channel tube C passed through the communication hole 5, and the second part 3 is also squeezed by the upper handle part 1d. By being pressed down by the push-down receiving part 3e, the second flow stop part 3b pinches the channel tube C, and this pinched state is held by the first and second holding parts 2d and 3d. After the cutter 4 cuts the channel tube C, the cutting thin wall 6b serving as the cutting part is cut off, and the second part 3 becomes separable.

Furthermore, in the embodiment shown in FIG.
The first upper protrusion 2a and the second upper protrusion of the flow stop parts 2b and 3b, respectively.
The upper protrusion 3a is difficult to deform as in the previous illustrated examples, but the first lower protrusion 2a' and the second lower protrusion 3a' are similar to the first and second upper protrusions 2a. , 3a in the first part 2 and the second part 3, respectively, in order to be able to curve and deform in the pressing direction when the first part 2 and the second part 3 are pressed.
The second elastic arms 3g, 3g are extended, and the free ends thereof are provided with upward protruding portions.

Therefore, according to the above structure, when the wall thickness of the channel tube C is relatively small, the thin wall 6b of the tube C and the cutting portion 6 can be cut by the cutter 4 as described above. Not only can it be reliably separated, but even if the channel tube C has a large wall thickness, when the first and second upper protrusions 2a and 3a press the tube C, the first Since the first and second elastic arms 2g and 3g of the second lower protrusions 2a' and 3a' can be bent downward, the flow stoppage of the first and second flow stop portions 2b and 3b is reliably performed. together with the first and second holding parts 2d, 3d
The holding state of the cutter 4 can be reliably obtained, and the cutting operation by the cutter 4 can be completed.

Here, what is shown in FIG. 4 is opposite to the configuration of the first and second flow stop portions 2b, 3b in FIG.
The first lower protrusion 2a' has a shape that is difficult to deform, and the first upper protrusion 2a is formed to be deformable from the extended state shown in FIG.

That is, the first upper protrusion 2a has a bending elastic part 2h formed in the middle part, and when the large diameter channel tube C is used as described above, this bending elastic part 2h can be bent. It is designed so that it can be in a reduced state.

In the above illustrated example, the first and second upper protrusions 2a,
3a and the first and second lower protrusions 2a', 3a',
Although only one side of the protrusion is elastically deformable to utilize a spring action, it is of course also possible to provide spring action on all protrusions on both the upper and lower sides.

According to the embodiment with the above configuration, even if there are variations in the wall thickness of the channel tube C, as described above, it is possible to sufficiently stop the flow, so that one disconnection tool is used. This provides versatility for various flow path tubes, and even when used for flow path tubes of a certain size, when manufacturing the disconnection tool according to the present invention, it is important to avoid dimensional shrinkage during molding. The wide range allows for easier production management, and the molds are also easier to manage.
This means that very high accuracy is not required.

<<Effects of the Invention>> Since the first invention of the present application is constructed as described above, it can be attached to the flow path tube by simply inserting it into the flow path tube, making it extremely easy for patients and workers to use. By manual operation, it is possible to quickly stop the flow of the tube, cut it, and separate the disconnection tool itself.As a result, even in the event of an emergency disaster, it is possible to quickly stop the flow of the tube, disconnect it, and separate the disconnection tool itself. This makes it possible to evacuate or separate dangerous objects without spilling blood or chemicals.

Moreover, in the present invention, the gripping main body is divided into the first part and the second part.
Since it is composed of a single member with an outer peripheral frame body having a section, it is easy to insert the channel tube, and it can be manufactured at a low cost. Therefore, after cutting the channel tube, it can be easily and quickly separated by manual operation.

Furthermore, when the cutting portion is at the position where it is to be cut by the cutter, cutting can be carried out by simply gripping the gripping main body.

Next, according to the second invention, not only can the above-described effects of the first invention be exhibited, but also by tightening the upper grip part and the lower grip part formed on the outer peripheral frame of the gripping main body, By pressing down not only the first part but also the second part with the upper grip body, it is possible to perform flow stoppage and its holding action, and therefore,
The operability can be improved by a simple action similar to operating a stapler, and sufficient external force can be applied to the cutting section with the cutter, and the second section can be made smaller. Even when the patient, etc. escapes in a hanging state after the amputation, a large load is not applied.

Since the present invention is molded from synthetic resin, if the arterial and venous arteries are molded in different colors, more effective measures can be taken at the time of installation or reuse.
