Abstract
The utility model relates to a human body transfusion apparatus flotage self-weight automatic needle closing device. A dripping hopper of the existing transfusion apparatus is improved by arranging a floater which is a column in the upper and a cone in the lower; the cone choke plug of the floater is provided with a soft elastic sleeve. When liquid flows in, the monitoring function of the dripping hopper is not changed; after the liquid flows out, the floater drops down caused by self weight; as a liquid outlet at the lower part of the dripping hopper is designed to be a cone, the cone choke plug of the floater can precisely plug the liquid outlet to avoid air from flowing into the human body and removing the medical troubles and accompany worries. The utility model is additionally provided with the floater based on the prior art which does not reduce the original functions, but increases the automatic needle closing function. The device has the advantages of simple structure, remarkable effect, easy implement and broad application range.
Description
Affiliated technical field
This utility model belongs to medical sanitary apparatus, and the medical supplies routinely that adopt when being a kind of human transfusion especially can close a kind of novel medical supplies of pin according to medicine liquid droplet after to the greatest extent automatically.
Background technology
Be to forbid the air admission venous during human transfusion.In order to prevent that this phenomenon from taking place, doctor and company and even patient are meticulous invariably in the reality, but also unavoidable carelessness causes the generation of accident.Therefore people wish to have a kind of device that can close pin when medicine liquid droplet is most automatically.But the application of rarely seen corresponding product in the medical practice.Trace it to its cause, or structure being too complicated, causing cost too high difficult with enforcement, is 200520059034.4 automatic controlling arrangement of transfusion system as application number.Application number is 03234447.3 technology, utilizes float to press the next lid that has shell fragment, thus the shutoff liquid outlet, also some difficulty in the enforcement.
Summary of the invention
The purpose of this utility model is to have overcome above-mentioned shortcoming, can utilize the buoyancy and the deadweight of float itself again under the prerequisite that guarantees former dropping funnel monitoring effect, directly the closing liquid path.
This utility model is achieved in that on dropping funnel housing top and is equipped with sealable loam cake, and loam cake central authorities are equipped with the inlet dropper, and the dropping funnel lower housing portion is the taper liquid outlet, and it is the float of taper for the cylindricality bottom that the dropping funnel housing is built-in with top.After flowing to medicinal liquid in the dropping funnel, float suspends, and opens the medicinal liquid path with the taper plug of float disjunctor, does not also influence the dropping funnel monitoring function; After fluid drips was most, float was owing to deadweight moves down, thereby the shutoff fluid path because the taper plug has put soft resilient sleeve, makes the respond well of closing liquid.Float of the present utility model also can be designed to forms such as sphere, T shape, but from being that assurance accurately falls into the taper liquid outlet and sealing effectiveness is taken all factors into consideration, it is taper and best with the form of soft resilient sleeve that the float upper end is designed to the column lower end.This utility model is simple in structure to be suitable for, and does not influence the monitoring function of former dropping funnel, and one-object-many-purposes is with low cost, wide application.This utility model is not found in the prior art.
Description of drawings
The utility model is described in further detail below in conjunction with embodiment of the present utility model and accompanying drawing.
Fig. 1 is the shape sketch map of this utility model embodiment.
Fig. 2 is the float profile of this utility model embodiment.
Fig. 3 is the soft resilient sleeve profile of this utility model embodiment.
Among the figure 1, loam cake, 2, the inlet dropper, 3, the dropping funnel housing, 4, liquid outlet, 5, float, 6, the taper plug, 7, soft resilient sleeve.
The specific embodiment
With reference to accompanying drawing, soft resilient sleeve 7 is tapered, can be made by silica gel one class non-toxic material, utilize its elasticity to seal, it is enclosed within on the lower taper plug 6 of float 5 and bonding, the float 5 that assembles is put into dropping funnel housing 3 after, loam cake 1 is built and is sealed.Then tube for transfusion is connected by former dropping funnel traditional approach with liquid outlet 4 with inlet dropper 2 successively.When transportation or dropping liquid flow to end and cause float 5 stuck can not come-ups, but soft dropping funnel housing 3 bottoms of pinching freely suspend float 5 when having liquid to flow into dropping funnel housing 3.
Claims (3)
