Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to suspension devices for medical containers. More specifically, the present invention relates to a suspension device for medical containers such as urinary bags that can be easily attached to and removed from hospital bed equipment and used.

PRIOR ART A medical container, for example a urine drainage bag which is closed from the outside world and is capable of collecting and storing urine, is a flexible synthetic bag equipped with a hanger part 1 at one end and a drainage tube 2 at the other end, as shown in FIG. A drip chamber 4 is provided on the hanger portion 1 side of the resin bag 3, and the drip chamber 4 is configured to be connected to a urine drainage tube 5. This urinary tube 5
A balloon catheter 6 is usually connected to the tube, and if necessary, a precision urine volume meter 7 is connected between the urinary tube 5 and the balloon catheter 6, and a necessary number of drains 8, 9 are attached. . Further, a cleanser 10 is attached to the drain tube 2 to control urine discharge.

When using such a urine drainage bag, after closing the drainage tube 2 with the clamp 10, the bag 3 is suspended from the bed rail 11 at the hanger part 1 by the suspension device 12, and the tip end 13 of the balloon catheter 6 is suspended. is inserted into the external urethral orifice, and inflation fluid is injected through the balloon inflation fluid injection path 14 to inflate the balloon 15 and fix it to the urethral orifice, thereby allowing urine to flow into the balloon catheter 6 through the side hole 16 and performing urinary catheterization. The urine flows into the bag 3 through the tube 5 and is collected. In this case, the air inside the bag 3 is replaced by the air filter section 17. The urine in the bag 3 is discharged from the drainage tube 2 by loosening the drain 10. In this way, using a closed urinary drainage bag prevents bacteria from entering through the connection between the catheter and the urinary tube, and the joint between the urinary tube and the urinary bag, thereby preventing urinary tract infections. ing.

However, such conventional urinary catheter bags are used suspended using a suspension device 2 as shown in Fig. 2, which not only makes it troublesome to put on and take off, but also prevents the patient from moving accidentally. Or if you suddenly stand up, the urinary bag will remain suspended from the suspension device 2 and will not come off.
If the connecting part or coupling part comes off or the balloon catheter 6 comes off from the urethral orifice, not only will urine leak to the outside, but the closed system will be ruptured and bacteria will enter from the place where it came off. There was a problem with the risk of urinary tract infection.

OBJECTS OF THE INVENTION It is therefore an object of the present invention to provide a novel suspension device for medical containers. Another object of the present invention is to provide a suspension device for a medical container such as a urinary bag that is easy to attach and detach from bed equipment such as a bed rail and is easy to use and is free from fear of rupturing the closed system.

These purposes include an elastic and rigid annular hook body having an opening at one location, and gripping a medical container on at least one of the ends of the annular hook and along the outside of the annular hook body. It consists of a gripping part that is integrally formed with a gap for the purpose and has a means for engaging with the outer wall of the annular hook near its end, and the annular hook main body is The annular hook body has an integral reinforcing rib with a projecting ridge, the opening width of the opening of the annular hook body is smaller than the diameter of the suspended member, and the opposite side of the annular hook body from the gripping part. A claw portion whose end portion is curved outward, the grip portion can be opened in a direction substantially opposite to the opening of the annular hook body, and the engagement is formed at the tip of the grip portion. It is formed by the engagement between the engagement protrusion on the annular hook main body side and the engagement protrusion on the tip of the locking piece that protrudes from the outer surface of the annular hook main body, and furthermore, a This is a suspension device for a medical container characterized in that a handle is integrally formed so as to protrude from an annular hook portion.

Specific Configuration of the Invention Next, an embodiment of the present invention will be described with reference to the drawings. That is, as shown in Figure 3, 1
an elastic and rigid annular hook body 22 having openings 21 at locations, and an annular hook body 22 for gripping a medical container at at least one of the ends of the annular hook body and along the outside of the annular hook body 22; This suspension device for a medical container includes a grip portion 23 integrally formed with a gap provided therebetween. Note that the annular shape herein is not limited to a circular shape, but may also be an inverted triangular shape, a rhombus shape, or a polygonal shape. At the tip of this gripping part 23,
A claw portion 24 forming a T-shape is integrally formed with the gripping portion, and an engaging protrusion 25 is formed at the end of the claw portion 24 on the side of the annular hook body. It engages with an engagement protrusion 27 at the tip of the locking piece 26 that protrudes from the outer surface of the locking piece 22 . This allows the grip portion 23 to open in the opposite direction to the opening 21 of the annular hook body 22. In addition, the annular hook body 2
A handle 28 is integrally protruded on the outer surface of the handle 2 so as to face the claw portion 24 of the grip portion 23 at a certain distance from the locking piece 26 . However,
The grip portion 23 of the opening 21 of the annular hook body 22
The opposite end portion forms a curved portion 29 outwardly with respect to the annular hook main body 22. At least one protruding reinforcing rib 30 is integrally formed on the outside of the annular hook main body 22. Also, near the opening on the gripping part 23 side inside the annular hook main body,
Reinforcing ribs 31, which are protrusions that protrude inward if necessary, are integrally formed. Further, the gripping portion 23
Similarly, reinforcing ribs (not shown) projecting outward are integrally formed on the outside of the holder, if necessary. Further, the opening 21 of the annular hook main body 22
It is desirable that the width of the opening is smaller than the diameter of the suspended member 11, such as a bed rail, as will be described later.

Such an annular hook body 22 and gripping part 23
The material of which it is constructed requires appropriate elasticity and rigidity. That is, as will be described later, when suspending the suspension device from the suspended member 11 such as a bed rail, the opening 21 is opened when the suspended member 11 passes through the opening 21, and the The annular hook main body must be able to expand and contract in diameter and have sufficient strength to suspend the medical container.

Such an annular hook body 22 and gripping part 23
A flexible synthetic resin is preferable as the material constituting the. Examples of such flexible synthetic resins include polyethylene (e.g., high-density polyethylene),
polypropylene, polyethylene terephthalate,
Polybutylene terephthalate, nylon-6, nylon-6,6, polyacetal, ABS resin,
There are hard vinyl chloride resins, etc. In particular, the connection part 32 between the end of the opening 21 of the annular hook body 22 and the clip part 23 needs to be flexible, since the claw part 24 at the tip of the clip part 23 opens and closes around the connection part 32. Become.

A suspension device for medical containers having such a configuration is
As shown in FIG.
3 and open the opening 33 of the urine bag hanger 1.
, the claw portion 24 is closed again, and then the suspended member 11 is pressed against the opening 21 of the annular hook main body 22, so that the annular hook main body 22 expands in diameter due to its flexibility, and the opening 21 opens, and after the suspended member 11 has passed, the diameter of the opening 21 is reduced and the opening width of the opening 21 returns to its original width. As a result, the medical container is suspended from the suspended member 11.

The above has been explained using a urine catheter bag as an example, but other medical containers such as infusion bags,
Of course, it can also be used for containers containing medical liquids such as blood bags and peritoneal dialysis bags (for example, continuous peritoneal dialysis (CAPD) bags).

Specific Effects of the Invention The medical container suspension device described above is used, for example, in the methods shown in FIGS. 5A to 5D. That is, as shown in FIG. 5A, hold the suspension device with both hands 52 and 53, hold the handle 28 with one hand 53, and press the claw portion 24 of the grip portion 23 against the outer end of the other hand 52. By doing so, the engagement of the engagement protrusions 25 and 27 with the locking piece 26 is released, and the grip portion 23 is opened from the annular hook body 22. Then, the fifth
As shown in Figure B, the gripping part 23 is inserted into the opening of the hanger part 1 of the urine drainage bag 3,
The hanger portion 1 is interposed in the space between the annular hook portion main body 22 and the annular hook portion main body 22. Furthermore, as shown in FIG.
re-engage them. Finally, the annular hook body 22
If, for example, the bed plate 11 is pressed against the opening 21 to expand the diameter of the annular hook main body 22, insert it through the opening 21, and then release it.
The annular hook main body 22 is reduced to its original diameter again, and the urine drainage bag 3 is suspended from the bed rail 11 as shown in FIG. 5D via the medical container suspension device.

Specific Effects of the Invention As described above, the medical container suspension device according to the present invention includes an elastic and rigid annular hook main body having an opening at one location, and at least one end of the annular hook. a gripping part that is integrally formed with a gap for gripping a medical container along the outer side of the annular hook main body and has means for engaging with an outer wall of the annular hook near its end; Not only is it extremely easy to attach the medical container to a bed, etc., but even if the user accidentally moves or stands up suddenly, the direction of the force will be the same as that of the grip. outward to the part,
That is, in the example shown in FIG. 3, the force is applied to the engaging protrusion side, and the force causes the engaging protrusions 25 and 27 to be disengaged, and the medical container is removed from the suspension device. Therefore, no excessive force is applied to the connections between the human body and the catheter, the catheter and the tube, and the tube and the medical container, so there is no fear that the connections will come off, and therefore the closed system from the human body to the medical container can be maintained. will not be torn. Therefore, there is no need to worry about infection due to closed system destruction.

Furthermore, if the annular hook main body and the gripping portion are made of flexible synthetic resin, they can be inexpensive, lightweight, and have appropriate flexibility. Furthermore, if the reinforcing rib of the protrusion protruding outward from the annular hook body is integrally formed, there is no need to worry about the annular hook body stretching downward even if the amount or weight of the liquid in the medical container increases. Moreover, it is possible to maintain appropriate flexibility at all times.
In addition, if the tip of the grip part is configured to releasably engage with the annular hook main body, the suspension can be ensured and it can be easily released by unexpected force. No excessive force is applied to the system, and there is no need to worry about damage to the closed system. Furthermore, if the end of the opening of the annular hook main body opposite to the gripping portion is curved outward, the attachment member can be easily inserted into the annular portion from the opening. moreover,
By making the opening width of the opening of the annular hook main body smaller than the diameter of the suspended member, when the suspended member passes through the opening, it opens easily due to the elasticity of the annular hook main body, but once it passes through. When suspended, even if a force is applied from another direction, it will not come off easily.

Furthermore, by making the gripping part openable in a direction substantially opposite to the opening of the annular hook main body, when a urinary bag is used as a medical container, for example, it can be suspended from a bed rail and drained by gravity. Therefore, the urinary tube is installed above the bag, and the suspended bag is located below the position of the human body, so if the person suddenly stands up, the bag should be turned in the opposite direction as mentioned above. This will cause the bug to come off. CAPD bags also use natural fall when draining fluid from the abdominal cavity, so a similar effect can be obtained. Furthermore, since the annular hook main body is elastic, even if the bag does not come off from the grip, the suspension device itself may come out through the opening.
