Abstract

The utility model discloses a disposable infusion set, belongs to the field of medical instruments, and aims to provide a disposable infusion set which has the advantages of simple structure, simple and easy operation, and safe use, can prevent air from entering the body of a patient, and reduces the workload of a medical staff. The infusion set comprises an upper infusion tube component, an infusion conversion clip, a dropping funnel component, a lower infusion tube component and a flow regulator, wherein, a plurality of upper infusion tubes penetrate the infusion conversion clip, the opening and the closing of the upper infusion tubes can be realized by adjusting an adjusting wheel on the infusion conversion clip, liquid medicines enter a dropping funnel from the upper infusion tubes through the multi-way joint at the upper part of the dropping funnel; a stop valve body clamped on a lower infusion tube joint at the lower part of the dropping funnel is arranged in the dropping funnel, and can move up and down, so as to realize the opening and closing of a lower infusion tube orifice. The utility model reserves all functions of common infusion sets, solves the problems that the workload of a medical staff is large and the patient is worried about that air enters the body of the patient, has simple structure and manufacturing process, and provides convenience for mass production.

Description

Disposable transfusion device

Technical field

The present invention relates to a kind of medical apparatus and instruments, particularly relate to a kind of infusion sets for single use.

Background technology

Medical treatment is at present gone up used disposable transfusion device in to patient's transfusion, mostly has following problem: the one, in infusion process, need frequent the running back and forth of medical worker to the patient changes liquid, and so just increased the weight of medical worker's workload; The 2nd, the patient worries not notify the medical worker in time after medicinal liquid is totally lost, and makes easily in the own body of air admission, so will pay close attention to transfusion device constantly.A kind of buoyancy aid spool that is contained in the dropping funnel is arranged in the prior art, and when the transfusion bottle inner liquid medicine was totally lost, buoyancy aid spool gravitate was blocked the lower port of dropping funnel, can prevent in the air admission body.A defective of this structure is that when continuing another transfusion bottle of extension, medicinal liquid flows into dropping funnel, because buoyancy aid spool lower end is no liquid, even can constitute negative pressure, the buoyancy that medicinal liquid produced in the dropping funnel can not make buoyancy aid spool come-up, causes the follow-up transfusion bottle can not normal infusion.

Summary of the invention

The objective of the invention is to address the above problem, provide a kind of and can alleviate medical worker's workload and can prevent the intravital disposable transfusion device of air admission patient, make the relieved use of user's energy.

The objective of the invention is to realize: a kind of disposable transfusion device by following scheme, it comprises upper tubing assembly, dropper component, following tube for transfusion assembly, flow regulator, it is characterized in that: the upper end of following tube for transfusion joint is set with the buoyancy aid valve gap that is moved up and down by buoyancy-driven, this buoyancy aid valve gap and the applying of the upper end edge of following tube for transfusion joint or the valve arrangement that separates the following tube for transfusion joint unlatching of formation control or close; The float valve hd top face is made the pit shape for ccontaining medicinal liquid, inside crozier is made in the bottom, the top of following tube for transfusion joint is shaped on annular projection, the conflict of the crozier of this annular projection and buoyancy aid valve gap constitutes float valve and covers floating position limiting structure, and tube for transfusion joint and buoyancy aid valve gap can not be broken away from.

Described upper tubing assembly has 1-3 medicinal liquid input, be serially connected with transfusion conversion folder between itself and the dropper component, be furnished with the groove more than at least two on the conversion clamp, tube for transfusion passes groove, groove is equipped with regulating wheel, and the regulating wheel of rolling makes tube for transfusion connect or close under the slant rail effect of transfusion conversion folder or changes flow.

Described float valve cup wall has the small through hole for the medicinal liquid circulation.

Described dropper component top has a multiple-pass joint can connect many upper tubings, and the bottom has one to connect the following tube for transfusion joint of tube for transfusion down.Medicinal liquid comes together in dropping funnel by the multiple-pass joint of upper tubing through dropping funnel top, and a checking-valve body is arranged in the dropping funnel, is stuck on the following tube for transfusion joint of dropping funnel bottom, can move up and down under the effect of medicinal liquid, realizes the opening and closing of the tube for transfusion mouth of pipe down.

The present invention has kept all functions of original transfusion device by some of original disposable transfusion device are improved, and the medical worker need not be again for the patient change frequent the running of liquid, the work of arranging oneself can rationally be arranged continuously; The patient also can oneself change liquid and eliminate and worry the intravital feared state of mind of air admission, can produce huge economic benefit after putting into production.

Description of drawings

Fig. 1 is the overall structure figure of disposable transfusion device;

Fig. 2 is the structure chart of transfusion conversion folder;

Fig. 3 is the state diagram of the valve body of dropping funnel when transfusion;

Fig. 4 is the state diagram of dropping funnel valve body when being totally lost liquid;

The specific embodiment

As Fig. 1, upper tubing (1) is connected with several different transfusion bottles respectively; As Fig. 2, push one of them regulating wheel (6) connection road medicinal liquid wherein of transfusion conversion folder (2) open, close the upper tubing that all the other several transfusion bottles connect; As Fig. 3, medicinal liquid enters dropping funnel (3) through multiple-pass joint (7), and checking-valve body (8) moves under the medicinal liquid buoyancy function, leaves down the sealing surface of transfusionization pipe joint (9), opens down tubing port and infuses; When a bottle liquid medicine wherein was totally lost, the upper tubing that it is corresponding was closed, and the upper tubing of opening another bottle liquid medicine just can continue transfusion; When medicinal liquid was totally lost, because of no medicinal liquid enters dropping funnel (7), the dropping funnel liquid level constantly descended; As Fig. 4, the effect of checking-valve body (8) loss of buoyance moves down under the deadweight and the effect of groove inner liquid medicine gravity thereof, compresses down the sealing surface of tube for transfusion joint (9) and closes down tube for transfusion.
