Abstract
The utility model provides an anti-springback type air inlet plug used for a transfusion bottle plug puncture device. An upper cover needs to be closed after an existing transfusion device is produced, and the upper cover of an existing transfusion device can be opened when the transfusion device is used in clinical transfusion. Therefore, a plastic bar is in a bent state and a memory is formed in storage and transportation process. A nurse can open the upper cover of the air inlet plug in clinical using process. The air inlet plug can gradually rebound and the air inlet plug finally blocks an air inlet passageway due to the bent memory, wherein the bent memory is formed by the plastic bar for a long time. Therefore, medicine liquid can not flow down and transfusion is stopped. Especially for critically ill patients, serious potential safety hazards exist. The anti-springback type puncture device used for the transfusion bottle plug consists of an upper cover, a base, an anti-springback device and a plastic bar. The anti-springback type air inlet plug used for the transfusion bottle plug puncture device can effectively prevent the upper cover from rebounding so as to block an air inlet, and the potential safety hazards in the transportation process are eliminated. The anti-springback type air inlet plug used for the transfusion bottle plug puncture device is simple in structure. Compared with an existing air inlet seat, the anti-springback type air inlet plug used for the transfusion bottle plug puncture device is low in cost and has popularization value.
Description
One, technical field
This utility model belongs to medical instruments field, is specifically related to a kind of anti-rebound type transfusion bottle stopper perforator inlet valve.
Two, background technology
bottle plug puncture unit is the clinical vein infusion set, as transfusion device, one of parts on the blood exchange transfusion set, when infusing, the patient is used for the transfusion bottle stopper that punctures, because the transfusion package of present clinical use mostly is greatly non-flexible package, as vial or plastic bottle, for ensureing normally carrying out of transfusion, bottle plug puncture unit need adopt air admission type, fluid passage carries medicinal liquid to replenish air by gas passage simultaneously, inlet valve is the vitals on gas passage, inlet valve commonly used is usually by upper cover, base and dowel three parts form, upper cover can repeat open or close, base is used for realizing the assembling of air filter on gas passage, before infusion set uses, upper cover covers on base, be in closed condition, on can the protective gas passage, air filter film material avoids damaged, when infusion set uses, need upper cover is in opening device always, guarantee that the normal of air replenishes.
but this inlet valve all adopts elastoplast to make at present, plastic bar can bend to guarantee that upper cover repeats open or close in production and use procedure, but there is great weak point in present clinical use procedure: need after production is complete due to infusion set upper cover is closed, until clinical transfusion is opened when using just now, therefore plastic bar is in bending state always, form memory in storage and transportation, in clinical use procedure, although the nursing staff opens the inlet valve upper cover, but due to the long-term bending " memory " that forms of plastic bar, inlet valve is resilience gradually, the final plant closure inlet valve, stop up recent passage, thereby cause the medicinal liquid can't be dirty, transfusion stops, there is great infusion safety hidden danger, particularly for critical patient.
In order to solve the problem of the easy resilience of above-mentioned inlet valve upper cover, wish to invent a kind of anti-rebound type transfusion bottle stopper perforator inlet valve.
Three, summary of the invention
This utility model can effectively solve the problem that air inlet is stopped up in the upper cover bounce-back that occurs in present inlet valve use, eliminates the potential safety hazard in infusion process, and in order to achieve this end, the technical scheme that adopts is:
This utility model has designed a kind of anti-rebound type transfusion bottle stopper perforator inlet valve, on the basis of original inlet valve, increases by a resilience-proof device, is comprised of upper cover, resilience-proof device and base, plastic bar.
The design of above-mentioned inlet valve is: upper cover, base and resilience-proof device are one-body molded.Upper cover and base link together by plastic bar, and resilience-proof device is connected with base, separate with upper cover and plastic bar, and it is 2～10mm that resilience-proof device protrudes the susceptor surface Partial Height, and the top is circular arc, can effectively stop resilience in the upper cover springback process.
The beneficial effects of the utility model are: the resilience-proof device in this utility model can effectively prevent the upper cover resilience and then stop up air inlet, eliminates the potential safety hazard that exists in infusion process, and simple in structure, and cost more now uses air inlet seat cheap, has promotional value.
Four, description of drawings
Fig. 1 is structural representation of the present utility model.
With reference to Fig. 1,1, upper cover; 2, base; 3, resilience-proof device; 4, plastic bar.
Five, the specific embodiment
With reference to Fig. 1, a kind of Improved-type infusion set air inlet seat is comprised of upper cover 1, base 2, resilience-proof device 3 and plastic bar 4.Upper cover 1, base 2, resilience-proof device 3 and plastic bar 4 elastoplast injection moulding integrated molding, upper cover 1 and base 2 link together by plastic bar 4, resilience-proof device 3 is between upper cover 1 and base 2, be connected with base, separate with upper cover 1 and plastic bar 4, it is 2～10mm that resilience-proof device 3 protrudes base 2 surface portion height, and the top is circular arc.
