DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indwelling catheter set for inserting urine into a bladder by inserting it into the bladder through an external urethral opening and collecting urine in a urine storage bag.

[0002]

2. Description of the Related Art When collecting urine, an open type is used in which a pus is easily received through a catheter inserted into the ureter, and a closed type in which a catheter is placed in the bladder and a urine bag or bottle is used. However, in both cases, the distal end of the catheter and the urine outlet are connected by a single flow path connecting the catheter and the urinary tube, and the latter is as shown in FIG.
The catheter 13 can be connected to the tip of the urine guiding tube 4 which is connected and fixed to the urine storage bag 1.

[0003]

When it is necessary to wash the bladder or inject a drug prior to or after the completion of urine collection,
The connection between the catheter and the urine drainage tube must be temporarily disconnected, and the catheter must be replaced with a cleaning tool such as an Illigator or Jane's washer, or a large syringe. In this replacement operation, although bacteria can cause urinary tract infection or the connection can be stopped with a clip, it may leak even though the amount is smaller than the connection site. Not desirable.

[0004]

SUMMARY OF THE INVENTION The present invention is an anti-bacterial infection as the maximum object, an indwelling catheter set which eliminates the complexity of recombinant work inserted simultaneously, its configuration, urinary
A catheter that can connect a catheter to the tip of the tube
The urine storage bag is attached to the base end of the urine drainage tube.
Physically connect, in the middle of the urinary tube, in the proximal direction
A branching part that branches off is provided, and the branching part is opposite to the tip side
The branch tube is led out in the direction, and the branch tube
And the above-mentioned urine drainage tube is provided with a pressing member , respectively. A Foley balloon catheter is preferably used as the catheter, and the branch tube can be made smaller in diameter than the urinary tube, or a closure cap can be detachably attached to the tip of the branch tube.

[0005]

[Function] Connect a cleaning tool or drug injector to the branch tube,
By alternately closing the tubes with the pressure-stopping member, the inside of the bladder can be cleaned and drugs can be injected without removing the urinary tube and replacing the device. or,
By using the catheter as a Foley balloon catheter , it can be left standing for a long time,
By making the urine drainage tube larger in diameter than the branch tube, urine is easily discharged into the urine storage bag without staying in the urinary drainage tube, and in combination with the obstruction by the obstruction cap, bacteria are not mixed in the catheter. Blocked, urinary tract infection rates are dramatically reduced.

EXAMPLES An indwelling catheter set according to the present invention will be described with reference to the drawings. In FIG. 1, 1 is a urine storage bag formed by combining two sheets of translucent synthetic resin sheets and sealing the periphery thereof, and a hexagonal shape in which the lower sides of the quadrangle are cut diagonally. , A scale is printed on the surface, the drain pipe 2 is provided at the lower end, and the grip 3 is cut out at the upper end. In the normal state, the drain pipe 2 has the pressure stop member 2a.
And is supported by being bent obliquely upward by locking the tip to the locking body 2b.

A base end of a urine drainage tube 4 is connected to an upper portion of a side surface of the urine storage bag 1, and a tip end of the urine drainage tube 4 is connected to one branch port of a bifurcated branch pipe 5. ing. A branch tube 6 is connected to the other branch port of the branch pipe 5, and a proximal end port of the branch pipe 5 is
A nipple 8 as a connecting member is connected via a joint 7, and these are integral with each other. Further, a closing cap 9 is provided at the tip opening of the branch tube 6, and an air filter 10 is provided at an upper corner of the urine storage bag 1.

Both the tubes 4 and 6 are highly flexible, and the branch tube 6 is thinner than the urine drainage tube 4. In the case of the embodiment, the inner diameter of the urine drainage tube 4 is 12 mm, and the branch tube 6 is
Has an inner diameter of 8 mm and has a structure in which urine collection is prioritized, and pressure-stopping members 11 and 12 are attached to the tubes 4 and 6, respectively.

In the indwelling catheter set thus formed, a catheter 13 for exclusive use in indwelling, such as a Foley balloon catheter or a malecot catheter, is connected to the nipple 8, and the branch tube 6 is provided as shown in FIG.
If the catheter 13 is occluded by the pressure-stopping member 12 and the catheter 13 is inserted into the bladder through the external urethral meatus and left in the bladder, the abdominal pressure can be applied to guide the urine in the bladder into the urine storage bag 1. It can be used like a catheter. Further, when washing, as shown in FIG. 3, the urine drainage tube 4 is closed by the pressure stop member 11 while the catheter 13 is connected, and the branch tube 6
After removing the closing cap 9 and connecting the cleaning tool 14 thereto, the pressure stop member 12 is unblocked and the branch tube 6 is opened. The procedure is the same when injecting a drug.

Although the urine storage bag of the embodiment has a hexagonal shape in the drawing, it may have a rectangular shape or a circular shape, and the structure and shape of the connecting portion and the pressure-stop member do not matter. Further, in the embodiment, a catheter for exclusive use for indwelling is connected and used, but a catheter other than the type for exclusive use for indwelling can be used as long as the catheter can be prevented from coming off.

The indwelling catheter set according to this embodiment includes a urinary tube 4, a branch tube 5, a branch tube 6, and a joint 7.
Also, since the nipple 8 and the nipple 8 are inseparable, there is no room for bacteria to enter and no replacement operation is required, which is extremely hygienic.

[0012]

According to the present invention, since the branch tube is integrally provided in the middle of the urine drainage tube, the bacterial infection caused by the insertion / removal operation can be prevented, and the treatment can be performed effectively.
