Abstract
The utility model discloses a silica gel urethral catheter with embedded guide wires. Independent tracts arranged on an inner wall surface layer of a catheter body of the silica gel urethral catheter and guide wires embedded into the independent tracts form the integrated silica gel urethral catheter with the embedded guide wires. The number of the independent tracts is 1-4, and the point positions of the four independent tracts are uniformly arranged on the inner wall surface layer of the catheter body of the silica gel urethral catheter. The independent tracts are node-free, smooth and straight in shape. The guide wires are made of one of stainless steel, medical polyethylene, medical polypropylene, medical nylon and carbon fibers, and the length of the guide wires is the same as that of the catheter body of the silica gel urethral catheter. The supporting performance of the urethral catheter is enhanced, and the urethral catheter is easily inserted and pulled especially for patients with uroschesis or urethrostenosis, so that discomfort and pain of the patients caused in the process of inserting and pulling the urethral catheter are prevented. The silica gel urethral catheter is easy to process and produce and low in cost.
Description
Technical field
This utility model belongs to the medical apparatus technical field, relates to a kind of silicone catheter, specifically, relates to a kind of silicone catheter that is embedded in seal wire that is provided with.
Background technology
Urethral catheterization is to rescue critical, shock patients, prepare and the dysuric means of urinating before the art of some operators, it is a routine operation of clinical nursing activity, it is one of fundamental operation common in the nursery work that catheter is inserted, used medical apparatus is silicone catheter, and its structure is comprised of sacculus and the joint that catheter main body and its two ends are respectively equipped with.The silicone catheter safety non-toxic, disposable use prevents cross infection.Along with applying of silicone catheter, be applied to indwelling catheter, in the bladder irrigation process, fixedly catheter is easy, has alleviated the patient suffering.But catheter is in the process of urinating, and catheter almost runs through urethra whole process, because the silicone catheter quality is soft, the problem that has intubate, difficulty in decannulation, particularly for the patient of urine retention or urethral stricture, have intubate when clinical operation, the situation of the very large difficulty of tube drawing happens occasionally.
At present, for having addressed the above problem following several approach;
One), change the silica gel materials prescription, improve the hardness of silica gel material, its result has reduced the silica gel material and has had good pliability.
Two), by increasing the pipe thickness of silicone catheter, to improve catheter strength character and hardness, its result has reduced the catheter internal diameter, and the urine flux is diminished, and has reduced urethral catheterization efficient.
Three), use outside seal wire when inserting catheter, the method is effective, but uses outside seal wire complicated operation, and catheter can be pullled distortion when extracting seal wire, causes suffering to the patient.
In the prior art, exist insertion to extract hard problem for solving catheter, the structure of catheter improved, and disclosed by following Chinese patent literature:
1, disclosed June 4 2008 Chinese utility model patent description Granted publication CN201067574Y Granted publication day " medical silica gel tube of embeded guidewire " at the silica gel catheter inner shaft to embedding at least one inelastic seal wire.Described seal wire material is various medical plastics or metal.
The weak point of its existence: the simple and function singleness of guide-tube structure, practicality is not enough.
2, disclosed July 5 2000 Chinese utility model patent description Granted publication CN2385738Y Granted publication day " steel core urinary catheter " at air bag silication latex catheter and added the steel core seal wire that coincide.The steel core seal wire is made with the steel wire of hard, and front 8 centimetres of seal wire is approximately 120 ° of bendings, the ellipse of top for slightly expanding, terminal handle for being connected mutually with the catheter collar extension.
3,2010 Chinese utility model patent description Granted publication CN201591901U Granted publication days JIUYUE " with the catheter of hard metal seal wire " on the 29th has disclosed urethral catheterization body urethral catheterization intracavity and has been equipped with the hard metal seal wire, there is bending body hard metal seal wire front portion, and the hard metal seal wire stretches out on the external rear end of catheter handle.
Above-mentioned 2 and 3 two exist same weak point: adopt external steel core, need during use seal wire is inserted and biocompatibility urethral catheterization body, and doctor's operating difficulties, the patient suffering is large.
The utility model content
The purpose of this utility model, aim to provide a kind of silicone catheter that is embedded in seal wire that is provided with, this catheter is when having silicone catheter biocompatibility and pliability and good hand touch characteristics, improved the strength character of catheter body, make it be easy to insert and extract, thereby overcome the problem that prior art exists.
For realizing this utility model purpose, the technical scheme that adopts is:
A kind of silicone catheter that is embedded in seal wire that is provided with, comprise sacculus, catheter body and joint is characterized in that: form and be integrally formed with the silicone catheter that is embedded in seal wire by independent tract being set at silicone catheter inboard wall of tube body surface layer and being embedded in seal wire at independent tract.
Described independent tract, it arranges number and is designed to 1-4, and wherein the some position of 4 independent tracts evenly is arranged on respectively on the silica gel tube inboard wall of tube body surface layer.
Described independent tract, its planform are without the unobstructed straight tract of tuberosity.
Described seal wire, by stainless steel material, the medical polyethylene material, medical polypropylene material, medical nylon material and carbon fibre material wherein a kind of material are made.
Described seal wire, its length and catheter body equal in length.
Beneficial effect
Compared with prior art, the beneficial effects of the utility model:
1, kept good biological property and the pliability of silica gel self.
2, seal wire has been strengthened catheter body supportive, make catheter more be easy to insert and extract, particularly for the patient of urine retention or urethral stricture, be easy to intubate and tube drawing, thereby prevent the generation that does not accommodate pain that causes to the patient because of in intubate and the tube drawing process.
3, compare with the common silicone catheter of same model, in the situation that same supportive requires, the thickness of pipe wall of the silicone catheter body of embeded guidewire can be accomplished thinner, thereby has improved the urethral catheterization flux.
