Abstract
The utility model relates to a sterile medical appliance, particularly a sealing and insulting plug which is fixed in the conduit seat of a venous indwelling needle. The venous indwelling needle sealing and insulting plug is made of elastic polymer medical-grade materials. The outer profile of the sealing and insulting plug is cylindrical. A ring-shaped groove is formed at the middle part of the sealing and insulting plug. A symmetrical crossed or Y-shaped cut-notch, of which the width is smaller than the minimum diameter of the sealing and insulting plug, is axially and uniformly cut from the rear part to the front part of the sealing and insulting plug until reaching the position that is 4/5 of the full length of the sealing and insulting plug. Compared with the prior art, the sealing and insulting plug has the advantages of reasonable design, simple structure, easy operation, convenient use and good sealing property, can effectively prevent the leakage of the drug solution or the blood when withdrawing the puncture needle, and can protect the medical staff or the patient against cross contamination or injury.
Description
Technical field
This utility model relates to a kind of aseptic medical equipment, especially relates to a kind of seal isolation plug in the vein indwelling needle catheter seat that is fixed on.
Background technology
Disposable use venous detaining needle claims the trocar again, as the regeneration product of venoclysis needle, is for the passage of medical institutions as vein treatment administration, fluid infusion and other turnover purposes, and can be retained in a kind of medical apparatus and instruments that designs in the Venous system in a short time.Usually and disposable infusion set or the supporting use of disposable sterilized syringe; Being applicable to needs the patient of long-term repeatedly transfusion to use, and has the vascular puncture of minimizing number of times, reduces intravenous extravasation, little to the stimulation of blood vessel, helps clinical application and urgent the rescue, reduces medical personnel's workload, reduces advantages such as patient infection's chance.Disposable use venous detaining needle popularize to use in American-European developed country before 30 years, and some developed countries and area replace venoclysis needle gradually and use in the Asia before 10 years.At present, the many medical institutions of China are all with the main utensil of venous detaining needle as the clinical transfusion treatment.
Disposable use venous detaining needle is made of protective sleeve, conduit tube component, needle tubing assembly, hose, calparine cap, tongs and end cap etc., and wherein conduit tube component is made up of conduit, metal wedge, seal isolation plug and catheter block.During use, the flexible pipe seat of venous detaining needle and transfusion device or syringe are connected the emptying bubble; The position that select to be fit to puncture, according to a conventional method after the sterilization, the puncture vein, see blood back after, the limit is extracted the puncture needle tube edge conduit is sent into vein, the needle tubing that will puncture is at last extracted fully, and catheter retaining in vein and fix, can repeatedly be infused to the patient.
In existing venous detaining needle uses, normal extracting owing to the puncture needle tubing, the seal isolation plug can not seal hole or the slit that stays after puncture needle is extracted fully, and cause the liquid of infusion or patient's blood to flow out from isolating consent or slit, and make patient and medical personnel's formation cross infection, patient and medical personnel are caused great injury.
And, in existing venous detaining needle production technology, it is normal because the hole opening technology of batching pig is bad, make the venous detaining needle product in assembling is produced, puncture needle can not well pass from centre bore, cause the puncture needle needle point to be broken, cause medical personnel's penetration Resistance big, patient's unfavorable condition such as have an intense pain.
Summary of the invention
This utility model just can solve the deficiency in the above-mentioned technology, and a kind of reasonable in design, simple in structure, easy to operate, easy to use, good seal performance is provided, and can effectively prevent the seal isolation plug that the medicinal liquid that produces when withdrawing from because of puncture needle or blood leak outside.
The purpose of this utility model is achieved in that the seal isolation plug made by the elastomer macromolecule medical material, and outside cylindrical, there is an annular groove middle part.The seal isolation plug is installed in the catheter block of remaining needle when using, and can glue be injected in the groove of seal isolation plug by two apertures of symmetry that catheter block is provided with, and the seal isolation plug is fixed in the catheter block; Again by special hole opening technology, make its from the rear portion position to anterior about seal isolation plug total length 4/5, dissectd uniformly vertically and be symmetrical cross the cut open trace of width less than seal isolation plug minimum diameter.Behind such hole opening technology, the cross or Y type of seal isolation plug cuts open the puncture needle that trace helps venous detaining needle and passes along seal isolation plug center, the puncture needle needle point is not broken, and do not produce buffings in the process of threading a needle.When extracting puncture needle, the cross trace that cuts open that the seal isolation plug is cut out can seal the pin hole that stays when puncture needle withdraws from immediately, and sealing fully.
This utility model compared with prior art has following advantage:
1, reasonable in design, simple in structure, easy to operate, easy to use, good seal performance;
2, leaking outside of medicinal liquid that produces in the time of can effectively preventing to withdraw from or blood because of puncture needle;
3, avoid pollution or injury to medical personnel or patient.

The specific embodiment
Below in conjunction with embodiment and contrast accompanying drawing this utility model is described in further detail.
As Fig. 1, Fig. 2, shown in Figure 3, this utility model relates to a kind of seal isolation plug that is fixed in the vein indwelling needle catheter seat, and is outside cylindrical, there is an annular groove 2 middle part, its diameter is 3～8mm, and length overall is 4～10mm, is made by the elastomer macromolecule medical material.In the venous detaining needle production and assembly, puncture needle passes from the axial center hole of batching pig, when using venous detaining needle, the puncture needle tubing is pulled out, the elasticity of dependence batching pig itself and catheter block inwall are to the pressure of batching pig, the hole or the slit that stay after the batching pig puncture needle can being extracted seal fully, can effectively prevent leaking outside of the medicinal liquid that produces when withdrawing from because of puncture needle or blood, avoid pollution or injury to medical personnel or patient.
The seal isolation plug is made by the elastomer macromolecule medical material, and outside cylindrical, there is an annular groove 2 middle part.By special hole opening technology, make its from the rear portion 1 position to anterior 3 about seal isolation plug total lengths 4/5, dissectd uniformly vertically to width and cutd open trace 4 less than seal isolation plug minimum diameter symmetrical cross or the Y type cuts open trace 5.
