Abstract
The utility model relates to a float-valve-type disposable infusion set capable of introducing medium into a body by means of subcutaneous injection, intravenous injection or intramuscular injection, which is the first choice for infusion in various kinds of institutions. The float-valve-type disposable infusion set consists of an upper delivery tube, a lower delivery tube, a needle and a drip chamber, wherein a float valve is arranged in the drip chamber; and a valve opening is formed at the bottom of the drip tube. The float-valve-type disposable infusion set has the advantages of simple structure, and easy implementation, and can meet the requirement of State Food and Drug Administration. The valve opening can be sealed automatically when the medical liquid almost drips off to ensure safety and reliability under unattended condition, so as to prevent the occurrence of medical accidents due to the invasion of air into the body, thereby alleviating the mental stress burden of accompanies and patients.
Description
Technical field
This utility model relates to a kind ofly introduces intravital apparatus with subcutaneous injection, intravenous injection or muscle injection mode with medium.Particularly a kind of disposable transfusion device that floats float-valve type is all kinds of medical institutions is patient's first-selected transfusion device of infusing.
Background technology
Well-known extension infusion is all kinds of medical institutions, to one of some disease treatment means commonly used, to obviously coming soon than the effect of oral medicine such as curative effects such as fever flu, some acute inflammations, also Just because of this, this treatment means is subjected to liking of hospitalized patients deeply especially.Yet however, be used to the disposable transfusion device of infusing in the past, when infusing, all will someone accompany and attend to usually to the patient, otherwise medicine liquid droplet to the greatest extent before, if untimelyly change dressings or pull out pin, if air admission blood can cause serious consequence.Particularly long to some gerontal patient's hospital stayss, often need long period or defeated simultaneously several medicinal liquids just more should pay special attention to, when especially infuse night, although the entourage observes when medicinal liquid drips off soon at any time, but owing to overtiredly one doze off slightly, situation about often causing the accident is heard of also the time.This situation also causes the concern of relevant departments, can regrettably up to the present still find no the report that successfully solves.
The utility model content
The problem that this utility model exists at prior art, when providing a kind of medicinal liquid liquid level in dropping funnel to level off to zero elevation, floating valve meeting automatic-closing valve stops to guarantee the safe and reliable disposable transfusion device that floats float-valve type in the transfusion blocking-up air admission body.
Another purpose of the present utility model be to provide a kind of simple in structure, implement easily, and meet state's food medicine prison tool relevant criterion requirement, the disposable infusion device that floats float-valve type with obvious social benefits.
The purpose of this utility model is achieved by the following technical solution:
Be made up of up and down catheter, syringe needle and dropping funnel, be provided with a floating valve in its described dropping funnel, the bottom of dropping funnel is provided with valve port.
The work surface of described floating valve and the work surface of valve port match.
A kind of in hollow spherical value that described floating valve is a medical soft silicone rubber and the floating plug valve.
Described hollow spherical value, its wall thickness are 0.3---0.5mm..
The shape of the valve body of described floating plug valve and the work surface of valve port are complementary.
The utility model has the advantages of as follows:
This utility model compared with prior art, owing to be provided with valve port in the bottom of dropping funnel, floating valve be located in the dropping funnel technical measures and through evidence have simple in structure, implement to meet again easily state's food medicine prison tool standard-required, medicinal liquid is the self closing valve mouth when dripping off, unattended also can guarantee safe and reliable, prevent to avoid taking place malpractice in the air admission body, remove and to accompany and attend to and the mental burden of patient's anxiety.If can obtain applying and have tangible economic and social benefit.
Description of drawings
Fig. 1 is a main TV structure sketch map of the present utility model.
Working state schematic representation when Fig. 2 is the dropping liquid end.
Among the figure: 1. go up catheter, 2. dropping funnel upper end plug, 3. dropping funnel, 4. floating valve, 5. medicinal liquid 6. descends catheter, 7. valve port.
The specific embodiment
Embodiment of the present utility model is described in detail in conjunction with the accompanying drawings.
Dropping funnel 3 prior art injection mo(u)lding as shown in Figure 1, floating valve 4 is loaded in the dropping funnel 3 from the dropping funnel upper port, be contained in together on the dropping funnel 3 behind the centre bore of last catheter 1 threading dropping funnel upper end plug 2, and maintenance secure fit, the lower port of being located at the valve port 7 of dropping funnel 3 bottoms links to each other with following catheter 6, the liquid outlet of following catheter 6 links to each other with syringe needle, and the medicinal liquid end that advances of last catheter 1 links to each other with the medicinal liquid bottle.Described floating valve 4 is with the medical soft silastic liquid, behind the former slip of deployed silastic liquid, according to its sphere diameter and wall thickness 0.3---behind the consumption injection mould of 0.5mm hollow ball, install on the centrifuge of multidirectional rotation, through even sticking the applying on mold wall of rotation silastic liquid, the hollow soft silicone rubber ball that forms is taken out in die sinking behind solidification process.Described floating valve is to make it eye-catchingly be convenient to observe also and the former slip of silicone rubber can be deployed into colour.Employed raw material all meets state's food medicine prison tool standard code in this utility model.
Described floating valve 4 also can be the floating plug valve that the work surface with injection molding, its work surface and valve port 7 is complementary.
When this utility model uses, basic identical with prior art, just when the nurse with medicinal liquid 5 input dropping funnels 3 in necessarily behind the medicinal liquid, floating valve 4 is under the buoyancy of medicinal liquid, swim on the liquid level, after regulating a speed, enter the normal infusion process, floating valve 4 falls with the decline of medicinal liquid face thereupon, when finishing near transfusion, the height of dropping funnel 3 intracavity medicinal liquid faces levels off to zero the time, and floating valve 4 is because loss of buoyance and falling automatically on the valve port 7, and its work surface matches in the work surface of valve port 7, self closing valve mouth 7 stops transfusion, also effectively prevents simultaneously in the air admission body as shown in Figure 2.Even unmanned nurse also can guarantee the safety of infusing, and then also eliminate entourage's anxiety and the mental pressure feared.Also be that the patient increases by one safety curtain in transfusion simultaneously.
