Abstract
The utility model relates to a bubble-prevention infusion device which comprises a bottle inserting needle, an exhaust pipe, an air filter, a burette, a dropping funnel, a bubble catcher, a hose, a flow regulator, a liquid medicine filter and an intravenous infusion needle, and is characterized in that the strip narrow-seam-type tapered bubble catcher is added in the dropping funnel and made of transparent medical polymer material. The operation mode, same with that of a conventional general infusion device, adopted by the novel infusion device is that the bubble catcher is used for catching the bubble in the liquid according to the surface tension of the bubble formed by the air and the liquid, so as to limit the bubble in the dropping funnel and allow the fluid to flow out; and the bubble catcher adopts the strip narrow-seam-type tapered structure, so that the flow requirement of the clinic infusion is met, the liquid medicine waste caused by the manual exhaustion by the medical staff is reduced, and the work efficiency is improved. Therefore, the bubble-prevention infusion device has the advantages of convenience in operation, simple structure, and easiness in automatic production.
Description
Technical field
This utility model relates to a kind of disposable infusion set, is the most conventional at present clinical use medical product, belongs to medical instruments field.
Technical background
In recent years, we find that in clinical nursing activity producing micro bubble in the infusion process is the problem that often runs in the clinical position.Particularly when infusion cephalosporins medicine, constantly produce micro bubble; After these bubbles get into human bodies as can not in time be dissolved in the blood; In the blood flow process, cause the blood vessel embolism phenomenon and flow into heart along blood; When these gases occupy ventricle, will hinder the circulation of blood, cause patient's rapid death easily.
In order to solve the air bubble problem in the clinical transfusion process; Usually after being employed in needle for inserting bottle insertion liquid medicine bottle stopper; With the Perfusion drip funnel reversal of the natural order of things, treat that medicinal liquid enters into the about half of dropping funnel and just dropping funnel just hung again, could solve the preceding bubble of transfusion; But the bubble that in infusion process, produces then needs medical personnel's conduit that constantly flicks to get rid of bubble, and such operating process has increased medical personnel's working strength and brought and big inconvenience to patient.
The utility model content:
In order to address the above problem, this utility model is to realize like this; A kind of its component parts of novel bubble-proof transfusion device is: needle for inserting bottle 1, exhaustor 2, air filter 3, dropper 4, dropping funnel 5, bubble trap 6, conduit 7, flow regulator 8, liquid medicine filter 9, venoclysis needle 10, venoclysis needle handle 11; Aerofluxus block 12, the rectangular narrow slit 13 of bubble trap; It is characterized in that; In dropping funnel 5, be provided with bubble trap 6, bubble trap 6 is the pyramidal structure of belt length bar narrow slit 13, and is provided with aerofluxus block 12 on the bubble trap top.
This utility model is with the general infusion set mode of operation is identical at present; In Perfusion drip funnel, bubble trap is designed to rectangular narrow slit type pyramidal structure; And be provided with aerofluxus block 12 on the bubble trap top; Utilize the bubble surface tension force of liquid-to-air formation, catch the bubble in the liquid, and in dropping funnel, let liquid get in the conduit through rectangular narrow slit 13 outflows of bubble trap smoothly the bubble prevention through the steam vent in the block of the aerofluxus on the air catcher.This utility model is designed to the long strip type pyramidal structure with bubble trap, can satisfy the needs of clinical transfusion flow.Also can make things convenient for medical personnel to get rid of bubble.
