Description

Dialyzer protective cap

Technical Field

The utility model belongs to the technical field of a medical instrument, concretely relates to cerini dialyser cerini helmet has novel structure, and sealing performance is reliable, and is economical and practical, makes things convenient for characteristics such as medical personnel operation.

Background

Today's society, the number of uremia patients rises year by year, blood purification is the important treatment means who maintains uremia patient's life, and the cerini dialyser cerini is the important medical instrument of blood purification treatment, direct and blood contact during clinical use, there is the product of fungus can direct influence patient life safety, in order to ensure the aseptic assurance level of cerini dialyser cerini, the cerini dialyser cerini is packed into aseptic barrier and is disinfected before dispatching from the factory, when clinical use, just the aseptic barrier has been lost after the product primary packaging is torn, if place the environment improper or time overlength, there is the pollution risk, installation protection helmet on the cerini dialyser cerini interface can avoid the cerini to receive the pollution, medical patient's safety has further been ensured, most cerini dialyser cerini all is furnished with the helmet in the existing market.

Disclosure of Invention

The utility model discloses the purpose of cerini dialyser cerini helmet provides a leakproofness good, and the assembly is dismantled simply, convenient to use's cerini dialyser cerini helmet. Its novel special structure can make the compatible cerini dialyser cerini end cover interface of helmet and dislysate interface, needn't distinguish when using, and the outside is equipped with anti-skidding tooth, makes things convenient for clinical use.

The purpose of the utility model is realized by the following technical proposal that a dialyzer protecting cap is internally provided with a plurality of fixing cylindrical surfaces, which is convenient for the protecting cap to be tightly pressed and fixed with a dialyzer end cover joint; an outer cylinder is arranged inside the dialyzer, is matched and fixed with an inner hole of a dialysate interface of the dialyzer and plays a role in sealing; an inner cone sealing joint is arranged inside the protective cap and can be matched with a 100 interface of the dialyzer end cover 6 of the dialyzer to achieve the sealing effect; a limiting step is arranged inside the bracket, so that the assembly is convenient; the outside of the protective cap is provided with a plurality of anti-skid teeth which are convenient to detach during use.

The utility model discloses the inside outer cylinder that is equipped with of cerini dialyser cerini helmet is fixed with the dialysate interface hole cooperation of cerini dialyser cerini to play sealed effect. The utility model discloses the cerini dialyser cerini helmet outside is equipped with a plurality of antiskid teeth, makes things convenient for clinical use. The material used by the dialyzer protective cap of the utility model is polyethylene, and the material is stable and is used by a large number of medical instruments, such as dialyzer shell, injector, etc. The dialyzer protective cap is formed by injection molding, has lower cost on materials and production process, and is beneficial to reducing the economic burden of patients. After the dialyzer is provided with the protective cap, the dialyzer cannot fall off and leak under the pressure of 2.0bar (the maximum pressure of the dialyzer in use generally does not exceed 66.5kpa), and the dialyzer is firmly matched with the dialyzer and has reliable sealing property. The design of antiskid tooth is adopted to the dialyzer protection cap outside, easily is snatched, is taken off by the nurse when using easily.

Detailed Description

The utility model relates to a novel dialyzer protective cap, which is economical and practical and is convenient for the operation of medical care personnel. The dialyzer protecting cap is structurally shown in figures 1 and 2, and as shown in figure 3, a plurality of fixing cylindrical surfaces 1 are arranged inside the protecting cap, so that the protecting cap and a dialyzer end cover 6 are conveniently pressed and fixed; an inner cone groove 3 is arranged in the protective cap and can be matched with a 100 connector 7 of a dialyzer end cover 6 of the dialyzer to achieve the sealing effect; as shown in fig. 4, an outer cylinder 2 is arranged inside the dialyzer protective cap, and is matched and fixed with an inner hole 8 of a dialysate interface of the dialyzer, and the dialyzer protective cap plays a role in sealing; the limiting step 4 is arranged in the dialyzer protective cap and is matched with the dialysate interface 9 of the dialyzer for limiting, so that the assembly is easy; as shown in figure 2, a plurality of anti-skid teeth 5 are arranged outside the protective cap, so that the dialyzer can be conveniently detached when in use. The raw material that cerini dialyser cerini helmet used is polyethylene, and the material price is lower, adopts injection moulding, and cerini dialyser cerini helmet novel structure is nevertheless simple, can adopt a mould multicavity production, and low in manufacturing cost is favorable to reducing patient's economic burden. The dialyzer protective cap is regular in appearance structure, automatic assembly can be achieved by the aid of the vibrating disc feeding and the automatic fastening device, and high-efficiency assembly is achieved in the dialyzer assembly process.
