Abstract
The invention discloses a kind of semi-round ball film automatic liquid-stopping transfusion apparatus, including woven hose, puncture outfit, dropping funnel, flow regulator, female Luer and transfusion needle, in described dropping funnel, be provided with a hemisphere automatic liquid-stopping device.The hemisphere automatic liquid-stopping device that the present invention uses is capable of automatic liquid-stopping, prevents liquid adverse current, prevents " blood back " phenomenon, and structure is the most ingenious, and simple in construction, practical.
Description
Technical field
The present invention relates to a kind of transfusion device, particularly relate to a kind of semi-round ball film automatic liquid-stopping transfusion apparatus.
Background technology
The transfusion device of market is varied at present, people are when using transfusion device transfusion, when especially defeated using up wanted by the liquid in infusion bottle, it is necessary to transfusion needle is extracted from human body, may result in " blood back " phenomenon if not extracting, so patient body is had the biggest harm.
Summary of the invention
The present invention is to solve the above-mentioned deficiency of prior art, it is proposed that a kind of semi-round ball film automatic liquid-stopping transfusion apparatus.
In order to solve above-mentioned technical problem, the present invention is by the following technical solutions: a kind of semi-round ball film automatic liquid-stopping transfusion apparatus, including woven hose, puncture outfit, dropping funnel, flow regulator, female Luer and transfusion needle, being provided with a hemisphere automatic liquid-stopping device in described dropping funnel, this hemisphere automatic liquid-stopping device includes the buoyancy aid being arranged in dropping funnel；Being a cavity structure inside described buoyancy aid, upper end closes, lower ending opening；Tank was vertically distributed with the upper side of described buoyancy aid, with the lower side of buoyancy aid, was provided with multiple inlet opening；Port, described buoyancy aid lower end is arranged with a semi-round ball film, and described semi-round ball film uses flexible film material to make, and the internal water outlet of described dropping funnel is provided with one and the taper projection snapping in described buoyancy aid lower end, described taper projection can be coordinated to be provided with a drainage hole.
The upper end of described buoyancy aid is provided with a transverse slat in being provided with water inlet a gross porosity, and cavity structure, and described transverse slat is additionally provided with a water outlet micropore.
Described woven hose uses two-layer pipe, and wherein, inner tube uses to be made without DEHP plasticizer material, and outer tube uses PVC material to make.
Compared with prior art, the present invention use semi-round ball membrane structure can transfusion will at the end of, blocking the drainage hole on taper projection, allow the liquid in dropping funnel cannot continue dirty, the liquid in buoyancy aid is the dirtiest simultaneously, keep liquid level pressure balance, stop " blood back " phenomenon up hill and dale, and total be simple, it is easy to accomplish, practical, it is worth significantly promoting.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is dropping funnel and the structural representation of buoyancy aid of the present invention.
Detailed description of the invention
With embodiment, invention is described in detail below in conjunction with the accompanying drawings.
As shown in Figure 1, 2, the semi-round ball film automatic liquid-stopping transfusion apparatus that the present invention proposes, including woven hose 1, puncture outfit 2, dropping funnel 3, flow regulator 4, female Luer 5 and transfusion needle 9, being provided with a hemisphere automatic liquid-stopping device in dropping funnel 3, this hemisphere automatic liquid-stopping device includes the buoyancy aid 6 being arranged in dropping funnel 3；Being a cavity structure inside buoyancy aid, upper end closes, lower ending opening；Tank 61 was vertically distributed with the upper side of buoyancy aid, with the lower side of buoyancy aid, was provided with multiple inlet opening 62；Port, buoyancy aid 6 lower end is arranged with a semi-round ball film 7, and semi-round ball film 7 uses flexible film material to make, and the internal water outlet of dropping funnel 3 is provided with one and can coordinate the taper projection 8 snapping in buoyancy aid lower end, and taper projection 8 is provided with a drainage hole 81.The upper end of buoyancy aid is provided with a water inlet gross porosity 63, and is provided with a transverse slat 64 in cavity structure, and transverse slat is additionally provided with a water outlet micropore 65.Woven hose 1 is bimetallic tube, and wherein, inner tube uses to be made without DEHP plasticizer material, and outer tube uses PVC material to make.
In one embodiment of the invention, being additionally provided with a cutting ferrule in dropping funnel, cutting ferrule is an empty rack-like, it is fastened in the top of buoyancy aid 6, when buoyancy aid rises by spacing for buoyancy aid at certain liquid level, prevent buoyancy aid when liquid level falls after rise, blocked by dropping funnel madial wall interface.
When infusing, liquid enters dropping funnel 3, liquid flows through from the tank of crossing of buoyancy aid 6, and buoyancy aid produces buoyancy in dropping funnel 3 inner liquid medicine and rises, liquid in dropping funnel 3 also can enter in buoyancy aid 6 from water inlet gross porosity 63 and inlet opening 62, flow out from drainage hole 81, be now full of liquid in the cavity of buoyancy aid, then semi-round ball film 7 is in the state heaved；When transfusion will at the end of, the liquid level of dropping funnel 3 declines, buoyancy aid 6 slowly sinks, when reaching the height necessarily fallen, taper projection 8 withstands semi-round ball film 7, semi-round ball film 7 flat enter and blocked drainage hole 81, when taper projection 8 pushes in buoyancy aid lower end completely, the liquid of buoyancy aid cavity inner horizontal plate less than 64 is extruded by taper projection 8 from inlet opening 62, and now, on in transverse slat more than 64 has previously been stored in cavity, liquid water outlet micropore 65 oozes, flow out in dropping funnel from inlet opening 62 again, material is thus formed a water-stop, keep the pressure balance of liquid level, thus thoroughly stopped " blood back " phenomenon.
Above-described embodiment only have expressed the several embodiments of the present invention, and it describes more concrete and detailed, but can not be therefore understands that be the restriction to the scope of the claims of the present invention.It should be pointed out that, for the person of ordinary skill of the art, without departing from the inventive concept of the premise, it is also possible to make some deformation and improvement, these broadly fall into protection scope of the present invention.Therefore, patent of the present invention and protection domain should be as the criterion with appended claims.
