Abstract

The utility model provides a medical pressure reducing tube which can prevent the clogging. The utility model is characterized in that an air bag with a plurality of pull wires is arranged at the double hollow soft catheter head section of an air injecting passage which is contained in a wall and a plurality of long and thin side holes are arranged on the catheter of one end of the bag; a guide steel wire can be inserted in the tube and when the tube is clogged, the medical pressure reducing tube injects the air to the air bag through the air injecting passage; the expanded air bag makes the tube head float out the liquid level and the side holes are opened through the pull wire; the obstruction is pushed away through a supporting edge of the hole or continuous air injection and air extraction make the side holes make the opening and closing movement as the bag moves; the obstruction is crushed or the crushed obstruction in the tube core is sucked out or taken out with the guide steel wire to achieve the effects of preventing the clogging and reducing the pressure.

Description

Medical catheter with function of compression release and plug-proof

This utility model relates to a kind of improved medical relief pipe, the anticlogging medical reduced pressure conduit of particularly a kind of energy.

Existing medical relief pipe mainly by a certain-length, head end has the rubber of one or more small side holes or the soft conduit of silica type to constitute.Chang Yong nasogastric tube, duodenum vessel, colonic decompression pipe, anal canal and catheter are exactly this form clinically.When the row gastrointestinal decompression, during the bladder urethral catheterization, conduit per os, nose, anus or urethra place are inserted to the position that needs to reduce pressure aspirate, discharge its content (food debris, hematocele, pneumatosis, feces etc.), with the situation that plays decompressing effect and observe stomach, intestinal, bladder position.But often stop up the conduit side opening because of gastrointestinal contents, intravesical hematocele, slough, gastrointestinal wall and wall of urinary bladder, cause the not good or failure of effect of easing stress, thereby delay treatment or replacing conduit not only cause unnecessary misery to patient, also increase nursing staff's labor intensity.

The purpose of this utility model is that a kind of improved medical anti-blocking relief pipe will be provided, and it can prevent effectively that food debris, feces, hematocele, slough, gastrointestinal wall etc. from stopping up conduit, carries out gastrointestinal, bladder decompression sustainably.

The purpose of this utility model realizes in the following way: in tube wall, contain an air bag gas injection road the medical reduced pressure conduit of dual-hollow head end slightly below, it is one inflatable to be with conduit upper gasbag gas injection road junction that the center is installed, fixing several symmetry draught line (silk threads, nylon wire etc.) latex balloon, the air bag tail end adorns one can make draught line vertically free, but the retainer ring that can not laterally slide, on its rear catheter wall, it is corresponding with the air bag draught line to open several, the elongated shape side opening, fixed traction line tail end on the peritreme of side opening balloon side far away, the draught line head end is crossed air bag and is fixed on the air bag head end, for making the draught line stage casing can only be vertical, and can not laterally slide, air bag coated outside one deck can be with the fixing capsule of the latex of inner bladder breathing, on the fixedly aperture corresponding with draught line arranged, air bag gas injection road head end in the catheter wall is to pipe external-open one osculum (air bag gas injection road junction), tail end connects a gas injection catheter adapter, be easy to be inserted to the decompression position and remove in the conduit and stop up material for ease of conduit, other is furnished with the nestable guide wire of a conduit.When stopping up appears in the conduit side opening, can in air bag, inject a certain amount of gas, make airbag inflation, the conduit head end can float on the liquid level, extracts the gastric pneumatosis out, simultaneously because of airbag inflation, the tractive draught line outwards struts the side opening support edge of air bag below, and side opening is opened greatly, support edge is pushed tamper open, and gastrointestinal and intravesical be tolerant to be able to sucking-off; This side opening also can be with the open and close movement of the continuous breathing row of air bag, and food debris, blood clot of getting lodged in the side opening place etc. is extruded into fragment, so as with it through the conduit sucking-off; If tamper blocks up in tube core, available guide wire is pulverized the back sucking-off with it or is directly taken out.Thereby play anti-blocking effect.The anti-blocking relief pipe of bladder also can place the air bag of band draught line the rear of side opening, side opening can open head section at conduit, and the conduit head end is opening in addition not.

The concrete structure of this utility model head section is provided by following examples and accompanying drawing thereof.

This conduit can divide I, II amphitypy.I type conduit comprises the soft catheter main body of hollow (1) of a certain-length, one air bag gas injection road (2) is arranged in the tube wall, air flue opening (3) is positioned at catheter main body head section, the sealing of outer wrapping one two ends is fixed on the catheter main body (1), length is greater than the latex balloon (4) of air flue opening (3), similar with one to this capsule size, with the fixing capsule (6) of the latex of several draught lines (5), the afterbody of two capsules has the draught line retainer ring (7) that is fixed on the catheter main body (1), have and the draught line number on its rear catheter main body (1), the corresponding elongated shape side opening in position (8), by side opening support edge (10) it is separated between adjacent two side holes (8), the head end of draught line (5) is fixed on air bag head (9), by the fixedly corresponding fixing hole of capsule (6) and the fixedly retainer ring of capsule afterbody (7), its tail end is fixed on the peritreme of side opening (8) balloon side far away, also can insert the slightly short conduit guide wire of a length in the hollow of catheter main body (1).II type guide-tube structure and I type are similar, but the air bag of catheter main body II places the back of side opening, and side opening is opened the head section at catheter main body.Catheter main body afterbody I, II type are all taken out thing joint and gas injection joint.

When using this conduit to reduce pressure, the nursing staff is inserted to catheter main body (1) head section earlier and needs the decompression position, be necessary that Shi Kexian is placed in conduit on the guide wire, to support and guiding catheter, the conductor housing section is put to decompression can extract steel wire behind the position, and the thing joint of taking out of suction device connecting duct is aspirated.When pipe obstruction occurring, in air bag (4), inject a certain amount of gas with syringe through gas injection joint, air bag (4) can make the conduit head end swim on the liquid level that needs in the relief chamber; Air bag (4) drive draught line (5) is opened greatly side opening (8) simultaneously, side opening support edge (10) outwards struts, push obturator open, or gas injection in air bag (4) constantly, bleed, air bag (4) makes side opening (8) carry out open and close movement by draught line (5), obturator is pulverized the back extract out; If catheter core (1) is blocked; But guide wire insertion tube in-core is pulverized sucking-off or directly taking-up with obturator.
