JPH0796029A - Bile reflux catheter - Google Patents

Abstract

PURPOSE:To avert the patient's pain by returning the bile discharged outside of the body from the biliary duct on account of a failure in the excision of the biliary duct part or the hypo-yellowing of a biliary duct stenosis patient to the duodenum not by oral intake. CONSTITUTION:This bile reflux catheter 1 is constituted by connecting a tube 1 for percutaneous indwelling in the biliary duct, a bile bag 2, a one-way valve 3 for suction, a pump function section 4, a one-way valve 5 for discharge and a tube 6 for percutaneously indwelling the duodenum in this order. The tube 1 for percutaneous indwelling in the biliary duct and the tube 6 for percutaneously indwelling the duodenum are respectively indwelt. For example, an elastic and restuitive elliptic cylindrical body is used as the pump function section and is intermittently pressed to deliver the bile from the biliary duct to the duodenum by the effect of the one-way valves on both sides.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bile reflux catheter used for refluxing bile discharged from the bile duct to the outside of the body to the duodenum in order to promote digestive absorption of a patient.

[0002]

2. Description of the Related Art For patients with unresectable malignant tumor in the bile duct or obstructive jaundice due to benign bile duct stenosis, percutaneous transluminal route from the liver to the bile duct is made, and a bile duct placement tube is used. It is generally practiced to place the intestine in the intestine and discharge bile out of the body or to flush the bile through the common bile duct into the intestine to reduce the amount of yellow. At this time, bile expelled from the body is usually stored in a bile bag, and the patient takes it orally to help digestion and absorption if necessary, and sends it to the duodenum. However, swallowing bile is a great pain for patients.

[0003]

In view of the above situation, the present inventors have investigated a method of returning bile expelled from the body to the patient's own body without forcing the patient to suffer oral intake, The inventors thought that it would suffice to form a cycle in which bile discharged from the bile duct to the outside of the body via an indwelling tube is allowed to flow back to the duodenum, and research was conducted on the device to complete the present invention.

[0004]

Thus, according to the present invention, a percutaneous bile duct placement tube, a bile bag as necessary,
There is provided a bile perfusion catheter characterized in that a suction one-way valve, a pump function part, a discharge one-way valve, and a duodenal indwelling tube are connected in this order. The structure of the catheter of the present invention will be described. FIG. 1 is a system diagram showing the configuration of the catheter of the present invention, in which a bile duct 2 is connected to a bile duct indwelling tube 1 that is placed percutaneously transluminally in the bile duct, and a suction one-way valve 3 is further connected. , The following pump function part 4,
The discharge one-way valve 5 and the duodenal indwelling tube 6 are connected in this order. The catheter may be formed as a pre-bonded set or just prior to bonding the members together. In the normal case, the bile bag 2 is incorporated, but it may be omitted depending on the condition of the patient and the suction one-way valve 3 may be connected to the bile duct indwelling tube 1. The bile duct indwelling tube 1 and the duodenal indwelling tube 6 are percutaneously punctured and perforated by a dilator to form a fistula tract reaching an organ, and the indwelling tube is inserted and fixed by a normal surgical method. it can. As the suction one-way valve, the discharge one-way valve, and the bile bag, commercially available products may be used.

[0005] The pump function unit 4 delivers the bile flowing down from the bile duct indwelling tube directly or delivers the bile stored in the bile bag to the duodenum.
Made of rubber pipe or plastic pipe, rich in elasticity,
After the pressing deformation, a tubular body 7 having a good restoring property, such as a tubular or elliptical bulge as shown in FIG. 2 and repeatedly pressing and releasing the pressing is used. In use, by pressing the tubular body 7 with a finger, the one valve on the discharge side is opened and the one valve on the suction side is closed. Next, when the pressing of the fingers is released, the tubular body is restored by elasticity and one valve on the suction side is opened and the discharge side is closed. As a result, the liquid or gas therein is sent from the suction side to the discharge side. As another example of the pump function unit, as shown in FIG. 3, a rigid tube 8 is branched and a syringe 9 is attached, and one valve on the discharge side is opened by manually pushing the syringe, and one on the suction side is pulled by pulling the syringe. The valve opens. As a result, the liquid or gas therein is sent from the suction side to the discharge side. In addition to the manual method described above, a pump function unit can be used as long as it can intermittently deliver in one direction by electromagnetically operating a small diaphragm type pump.

[0006]

[Function] After the bile duct indwelling tube and the duodenal indwelling tube are attached, the bile that flows down from the bile duct and is stored in the bile bag does not flow back due to the action of one valve on both sides of the pump by manually operating the pump function part. Sent to. Of course, depending on the patient's condition, bile from the bile duct can be sent to the duodenum without passing through the bile bag.

[0007]

INDUSTRIAL APPLICABILITY According to the present invention, oral ingestion of bile, which is very painful for patients, can be avoided, and bile can be moved in a closed cycle from the outside air. There is no fear. It is also convenient because the patient can operate it by himself / herself when needed. Furthermore, the one-way valve and pump function parts have the advantage that they can be washed and sterilized as needed.
