Abstract
A stomach catheter core consists of a handle, a bendable stainless steel wire, a safe spring and a smooth cheese head; the diameter of the stainless steel wire is about 1mm; the rear end of the stainless steel wire is provided with a fixed handle; the front end of the stainless steel wire is clipped and fixed on the rear end of the safe spring; the front end of the safe spring is provided with a smooth cheese head; the safe spring and the smooth cheese head is completely processed together. The utility model provides a stomach catheter core which helps a stomach catheter to be more easily and safely inserted without being vomited out.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, and specifically a kind of Stomach catheter core is used for being used in combination with stomach catheter, solves the problem that clinical part critical patient inserts the stomach catheter difficulty.
Background technology
At present, the silicone rubber stomach catheter of clinical use and latex three chambeies two capsule stomach catheter are soft because of pipe shaft, and strength can not pass to far-end effectively during insertion.Can not cooperate critical patient's difficult intubation often of making swallowing act.And, the problem that stomach catheter is rejected often appears in the process of inserting stomach catheter.
Summary of the invention
The purpose of this utility model is intended to overcome above-mentioned the deficiencies in the prior art, proposes a kind of stomach catheter that makes and inserts convenient, safety, the not Stomach catheter core that can be rejected.Solve the part patient and insert the problem that stomach catheter inserts difficulty.Insert the back and extract Stomach catheter core out, do not influence the normal use of stomach catheter.
Realize the technical scheme of above-mentioned purpose: Stomach catheter core comprises flexible stainless steel silk and safety spring, at the fixing safety spring of the front end of stainless steel silk.
The rear end of described safety spring and the front end of stainless steel silk connect and fix, the smooth socket cap of front end tool of safety spring, and safety spring and smooth socket cap projection integral body are processed as one.
Fixedly connected with one handle in the rear end of described stainless steel silk.
The diameter of described stainless steel silk is 1mm.
Adopt technique scheme, this utility model beneficial technical effects is: 1, adopt the Stomach catheter core of being made by flexible stainless steel silk and safety spring, during use, earlier Stomach catheter core is inserted in the stomach catheter, and then the stomach catheter that will be inserted with catheter core carries out intubate to patient.Because support stomach tube by flexible stainless steel silk, the strength when making intubate can be delivered to the stomach catheter front end effectively by stainless steel silk, overcomes the frictional force of stomach tube and body cavity.2, the problem of effectively avoiding stomach catheter to be rejected.3, by safety spring is set, the hardness of appropriate design safety spring has guaranteed can not cause damage to body cavity, has avoided stainless steel silk to pass the probability that causes human body harm from the stomach tube side opening.4, this utility model is tested through actual clinical, is used with stomach catheter, can obviously improve the insertion success rate of stomach catheter, solves the part patient and inserts the problem that stomach catheter inserts difficulty.5, insert the back and extract Stomach catheter core out, do not influence the normal use of stomach catheter.In sum, this utility model is simple in structure, ingenious, safe in utilization.
Below by embodiment, and in conjunction with the accompanying drawings this utility model is further described:
Description of drawings
Fig. 1 is a kind of structural representation of Stomach catheter core.
The specific embodiment
As shown in Figure 1, a kind of Stomach catheter core, form by handle 1, flexible stainless steel silk 2, safety spring 3 and smooth socket cap 4, the about 1mm of the diameter of stainless steel silk, the rear end of stainless steel silk 2 connects and fixes handle 1, the rear end of the front end of stainless steel silk 2 and safety spring 3 connects and fixes, the smooth socket cap 4 of the front end tool of safety spring 3, and safety spring 4 is processed as one with smooth socket cap 4 globalities.
During use, earlier Stomach catheter core is inserted in stomach catheter or three chambeies, the two capsule stomach catheter, and then the stomach catheter or three chambeies, the two capsule stomach catheter that will be inserted with catheter core carry out intubate to patient, easy to use, safe.
