Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a urinary tube for collecting urine in a urine storage bag by connecting a catheter inserted into the bladder from the urethral opening of the patient and retaining the urinary bladder, and a laparotomy, for example. The present invention relates to an extension tube connected to a catheter, such as a drainage tube used for discharging pus and the like from the body via a catheter inserted into the body.

[0002]

2. Description of the Related Art A catheter extension tube represented by a urinary tract or drainage tube (hereinafter simply referred to as an extension tube).
As shown in FIG. 6, a nipple 8 as a catheter connecting portion is provided at the distal end, and a liquid storage bag (urine storage bag 2) is integrally attached to the proximal end or detachably attached. Conventionally, each of them has been constituted by only one tube (urinary tract 1).

[0003]

The catheter is used not only for discharging unnecessary liquids from the body but also for injecting a washing liquid or a drug into the body. Taking urinary tube as an example, when performing bladder irrigation during urination, disconnect the catheter from the extension tube, and then use a cleaning tool such as an irrigator or Jane irrigator or the tip of a large syringe. Had been replaced with a catheter. In this replacement operation, it will give an opportunity for bacteria to enter the catheter from the connection portion, causing urinary tract infection,
There is a possibility that urine may leak when the connection is disconnected, which is not only unfavorable in terms of hygiene but also requires a complicated replacement operation.

[0004]

SUMMARY OF THE INVENTION The present invention is directed to an extension tube for preventing bacterial infection and at the same time eliminating the complexity of replacement work. The branch tube is led out from the branch portion, and the branch tube is provided with a flexible portion having a length that can be pressed at least with forceps, and a detachable closing cap is provided at the distal end, or the branch tube is provided with: A check valve is provided to allow the passage of fluid in the direction of the catheter connection. Then, the branch portion may be provided at the root of the catheter connecting portion, and the branch portion, the catheter connecting portion and the short branch tube may be integrally formed of a soft synthetic resin, or a three-way valve may be provided at the branch portion.

[0005]

The washing liquid and the medicine can be injected by connecting the washing tool and the medicine injector to the branch tube without disconnecting the catheter. Backflow to the branch tube can be handled by pressing the flexible part with forceps or the like, and if the branch part is provided at the base of the catheter connecting part and the branch tube is shortened,
Hard to get in the way. In addition, if a check valve is provided in the branch tube, it is not necessary to close the branch tube each time. If a three-way valve is provided in the branch portion, switching the three-way valve eliminates the need to close the tube. Become.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An example in which an extension tube according to the present invention is applied to a urinary tube will be described with reference to the drawings. In FIG. 1, reference numeral 1 denotes a urethral tube corresponding to an extension tube, and a liquid storage formed at the base end by combining two sheets of a synthetic resin sheet having a light-transmitting property and sealing a peripheral edge thereof. A urine storage bag 2 as a bag is attached, and the urine storage bag 2 has a hexagonal shape in which the lower sides of a quadrilateral are cut diagonally, a scale is printed on the surface, and a drain is provided on the lower end. A pipe 3 is provided, and a gripper 4 is cut out at the upper end. The drain pipe 3 is normally closed by a pressing member 3a, and is supported in a state of being bent obliquely upward by locking a distal end thereof to a locking body 3b.

The distal end of the urinary canal 1 is connected to one branch port of a bifurcated branch pipe 5. A branch tube 6 is connected to the other branch port of the branch tube 5. The branch tube 5 is connected to a catheter at the base of the nipple 7, together with the nipple 7 and the branch tube 6. Are formed integrally. Further, a threaded closing cap 8 is provided at an opening at the distal end of the branch tube 6, and an air filter 9 is provided at one upper corner of the urine storage bag 1. The urinary canal 1 is also very flexible,
The urinary tract 1 is provided with a pressing member 10 so that the urinary tubing 1 can be appropriately closed by the pressing member 10.

[0008] The urinary tract thus formed is placed in the nipple 7 with a catheter 1 for indwelling only, such as a Foley balloon catheter or a malecot catheter.
1 is connected, the catheter 11 is inserted into the bladder from the external urethra orifice, and is left in place. By applying abdominal pressure, urine accumulated in the bladder can be led out into the urine storage bag 2.
In the case of washing, as shown in FIG. 2, the urinary tract 1 is closed with the attached pressure-stopping member 10 while being connected to the catheter 11, the branch tube 6 is closed with forceps 12, and the closing cap 8 is closed. After removing and connecting the cleaning equipment 13 to it,
By simply removing the forceps 12 and opening the branch tube 6, it is not necessary to pull out the ureter from the catheter each time. The operation is the same when injecting a drug.

Since the branch tube and the nipple are formed integrally with the branch tube, the urinary tube of this embodiment has no room for bacteria to enter, and is extremely sanitary. It does not get in the way due to the operation, and the short urinary tract made of a soft synthetic resin makes it less uncomfortable to touch the skin. In addition to vinyl chloride, a soft and flexible synthetic resin material such as polyethylene and polypropylene can be suitably used for the integrally formed branch pipe.

[0010] The urinary canal of the embodiment has a structure in which a urine storage bag is attached to the proximal end and the urine storage bag cannot be removed.
The position of the branch portion, the length of the branch tube, and the like can be freely set. In addition, as shown in FIG. 3, a check valve 14 having an x-shaped cut is provided at the tip of the branch tube 6, for example, at the center of the valve membrane 14a, or as shown in FIG. A three-way valve 15 is provided for switching so that backflow can be prevented without injecting the branch tube each time when injecting a cleaning liquid or a medicine. The extension tube of the present invention is not limited to the ureter,
As shown in the figure, the present invention is also applied to an extension tube for drainage in which the branch tube 6 is led out from the middle of the drainage tube 1 ′. In this case, the position of the pressing member 10 'may be anywhere, and if it is movable, the operability is excellent.

The branch tube must be provided with a flexible portion having a length of about 1 cm which can be pressed by the forceps in consideration of the case where the forceps is used to close the branch tube. The flexible tube may be appropriately changed, for example, by using a pressing member instead of the forceps, partially providing a flexible portion, or adopting a plug-in type cap. Further, the form of the liquid storage bag is not limited to the embodiment, and a bottle or a can can be used instead.

[0012]

According to the present invention, since the branch tube is led out from the middle of the extension tube, bacterial infection caused by the insertion / removal operation for connecting the instrument is prevented,
It is possible to perform the treatment efficiently. If the branch portion is provided at the base of the catheter connecting portion, and the branch portion, the catheter connecting portion, and the short branch tube are integrally formed of a soft synthetic resin material, it does not easily become a hindrance even when worn, and the skin There is little discomfort even when touching. Further, if a check valve is provided in the branch tube or a three-way valve is provided in the branch portion, the switching operation between the extension tube and the branch tube can be performed with one touch without using a pressing member or forceps.
