しば起こった。However, since all such balloon materials are formed of a tubular body having one end closed or both ends opened, a balloon having a constant film thickness is manufactured. However, it was difficult to produce a tubular body with uneven thickness. Therefore, when the drug solution is flowed into the tubular body to expand the tubular body, the concentration of stress partially occurs and the shape of the balloon during expansion is deformed. The purpose of the present invention is to constantly inject the liquid medicine into the human body at a constant speed due to the fluctuation of the liquid medicine outflow rate at the balloon outlet when the liquid medicine is flowed out and the fluctuation of the liquid medicine inflow pressure at the inlet of the flow rate control unit. It often happened that was not achieved.

きる。The present invention is to inject the drug solution in the balloon into the patient by utilizing the contracting force of the balloon which is filled with the drug solution and expanded. The drug solution is injected into the patient from a puncture needle connected to a connector at the lower end of the drug solution flow tube. The inflow of the drug solution into the balloon is performed by joining the drug solution filled in the syringe of the syringe to the lock adapter of the drug solution flow port installed on the rotating disk, and rotating the rotating disk to rotate the cylindrical drum. This is done by matching with the mouth provided on the peripheral wall. The thickness unevenness of the sheet-shaped balun having a planar structure is smaller than that of the tubular body, so that the thickness unevenness of the balloon when the sheet is expanded by injecting a drug solution is also small. . As a result, there is little pressure fluctuation when the chemical solution flows out from the balun, and the balun filled with the chemical solution has no fluctuation in the outflow rate of the chemical solution at the balun outlet, so the chemical solution at the inlet of the flow control unit is not changed. The liquid medicine can be constantly injected into the human body at a constant rate without fluctuation of the inflow pressure.

流出した。[Comparative Example 1] A polyethylene tubular body (inner diameter 4.3 mm, outer diameter 4.6 mm, length 60 mm) with one end closed was folded in the vertical axis direction, and the outer surface near the closed end was dipped in silicone oil. -A film of oil was formed. On the other hand, vulcanized natural rubber tubular body (made by Komine Rubber Co., Ltd.) with one end closed
Was treated in the same manner as in Example 1 to produce a treated natural rubber tubular body (inner diameter 5.0 mm, outer diameter 7.0 mm, length 95 mm). Insert the polyethylene tubular body whose outer surface near the closed end was coated with silicone oil into the treated natural rubber tubular body, and further inject silicone oil into the gap to fix the openings of both tubular bodies. After that, both tubular bodies were expanded by injecting compressed air into the polyethylene tubular body. After the length of the treated natural rubber tubular body was cut so as to fit the polyethylene tubular body, the cut portion of the natural rubber tubular body was closed. Then, the air inside the both tubular bodies was discharged to manufacture a balloon. Silicon present in the gap between both tubular bodies
The oil layer covers the entire surface and its average thickness is
It was 0.09 μm. Using the balloon thus manufactured, a balloon body a for injecting a chemical solution as described in JP-A-4-967671 is molded, and 100 ml of water is injected into the balloon from a syringe of a syringe. did. There was no space between the polyethylene tubular body and the natural rubber tubular body, and the inner surface of the natural rubber tubular body was in close contact with the outer surface of the polyethylene tubular body and the balloon expanded. Then, by connecting the connector portion and the lock adapter of the chemical liquid outflow assembly b shown in FIG. 1, the water in the balloon was flown out to the chemical liquid flow tube side.

で口部での薬液の液洩れがないEFFECTS OF THE INVENTION Since the sheet-shaped balun having a planar structure has a thickness unevenness smaller than that of the tubular body, the balun when the sheet is expanded by injecting a chemical solution Thickness unevenness is also small. As a result, there is little pressure fluctuation when the chemical solution flows out from the balun, and the balun filled with the chemical solution has no fluctuation in the outflow rate of the chemical solution at the balun outlet, so the chemical solution at the inlet of the flow control unit is not changed. The fluctuation of the inflow pressure is small, and the liquid medicine can be constantly injected into the human body at a constant rate. In addition, the inflow and outflow of the drug solution can be performed only by matching the drug solution flow port of the rotary disk with the port part of the cylindrical drum, so that the operation is easy and the drug solution does not leak at the port part.
