preparation example Construction

[0080] As a preferred technical solution, the preparation method of the polytetrafluoroethylene anticorrosion layer at least comprises the following steps:

[0081] (1) Add polytetrafluoroethylene emulsion, emulsifier, chitosan, aminosilane coupling agent, polyether-polyester block copolymer and the rest of the water into the reactor, and stir to obtain mixture A ;

[0082] (2) Apply the mixture A to the waterproof layer and dry it under the condition of 80-100° C. to obtain the polytetrafluoroethylene anti-corrosion layer.

[0083] The applicant found that by using the structure of the multi-layer balloon provided by the present invention, the elasticity, compression resistance, anti-corrosion and waterproof performance of the balloon can be improved, and the instability of the balloon under external force or corrosion during use can be reduced. In addition, each layer is bonded by a polar adhesive to avoid damage to the balloon or shedding of the polytetrafluoroethylene lay...

Embodiment 1

[0086] see Figure 1-6, the present embodiment provides a technical solution: a double-balloon catheter device for gastrointestinal anastomosis, including a first balloon infusion tube 1, a positioning balloon infusion tube 2, a catheter housing 4, a pressure-resistant layer 71 and a second Balloon infusion tube 10, one end of the catheter housing 4 is equipped with a wire harness ring 3, and the inner wall of the wire harness ring 3 is equipped with a first balloon infusion tube 1, a positioning balloon infusion tube 2 and a second balloon infusion tube Infusion tube 10, the other end of the first balloon infusion tube 1 is equipped with a second balloon liquid inlet port 13, the first balloon infusion tube 1 communicates with the first balloon, and the positioning balloon infusion tube 2 The other end of the second balloon infusion tube 10 is equipped with a positioning balloon liquid inlet interface 12, the positioning balloon infusion tube 2 communicates with the positioni...

Embodiment 2

[0089] The difference between this embodiment and Embodiment 1 is that the anti-corrosion layer is a polytetrafluoroethylene anti-corrosion layer. The preparation raw materials of the polytetrafluoroethylene anti-corrosion layer include 30wt% polytetrafluoroethylene emulsion by weight percentage, and the polytetrafluoroethylene emulsion is purchased from Dongguan Yidingfa Plastic Co., Ltd., brand: American DuPont DISP 3885, 5wt% emulsifier, 3wt% chitosan, 0.5wt% aminosilane coupling agent, 12wt% polyether-polyester block copolymer and the rest water.

[0090] The emulsifier is a mixture of fluorine-containing alkyl alcohol polyoxyethylene ether and fatty alcohol polyoxyethylene ether glucoside, and the mass ratio of the fluorine-containing alkyl alcohol polyoxyethylene ether and fatty alcohol polyoxyethylene ether glucoside is : 1: 0.1, the weight ratio of glucoside and fatty alcohol polyoxyethylene ether in the fatty alcohol polyoxyethylene ether glucoside is 70: 30, and the ...

Abstract

The invention provides a double-balloon catheter device for gastrointestinal anastomosis. The device comprises a first balloon infusion tube, a positioning balloon infusion tube, a catheter shell, a pressure-resistant layer and a second balloon infusion tube, wherein a first balloon infusion tube, a positioning balloon infusion tube and a second balloon infusion tube are installed on the inner wall of the wire bundling ring, a first balloon, a positioning balloon and a second balloon are installed on the outer wall of the catheter shell, and the first balloon, the positioning balloon and the second balloon are sequentially arranged from left to right; a surface of the first balloon and the surface of the second balloon are made of the same material, and the surface material of the first balloon and the surface material of the second balloon each comprise a compression-resistant layer, a reinforcing layer and a protective layer. A patient does not feel pain in use, the transverse intestine can be well fixed, meanwhile, the balloon has good size stability and mechanical property, it can be guaranteed that work is safely and stably conducted, and practicability is high.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to a double-balloon catheter device for gastrointestinal anastomosis. Background technique [0002] Gastrointestinal anastomosis is suitable for patients with unresectable gastric pyloric tumors, gastric ulcers causing pyloric obstruction, and duodenal ulcers complicated by pyloric obstruction who cannot tolerate subtotal gastrectomy. This operation is simple and takes a short time. [0003] However, the existing double-balloon catheter device for gastrointestinal anastomosis has the following defects: [0004] (1) The existing double-balloon catheter device for gastrointestinal anastomosis cannot fix the transverse intestine well, and the treatment effect is poor. [0005] (2) The dimensional stability of the existing double-balloon catheter device for gastrointestinal anastomosis is not perfect, the elasticity is poor, and there is a risk of uncontrollable size. [0006...
