Abstract
The utility model discloses a hemisphere membrane automatic liquid stop infusion apparatus, which comprises an infusion tube, a puncture device, a drip chamber, a flow speed regulator, a Luer taper and an infusion needle, wherein a hemisphere automatic liquid stop device is arranged in the drip chamber. The hemisphere automatic liquid stop device adopted by the utility model has the advantages that the automatic liquid stop can be realized, the medicine liquid back flow is prevented, the occurrence of blood return phenomenon is prevented, the structure is very ingenious, in addition, the structure is simple, and the practicability is high.
Description
Technical field
This utility model relates to a kind of transfusion device, relates in particular 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, when using transfusion device transfusion, when especially the medicinal liquid in infusion bottle is wanted defeated using up, just need to extract transfusion needle from human body, if do not extract, will cause " blood back " phenomenon, like this patient body be had to very large harm.
Utility model content
This utility model, in order to solve the above-mentioned deficiency of prior art, has proposed a kind of semi-round ball film automatic liquid-stopping transfusion apparatus.
In order to solve the problems of the technologies described above, this utility model is by the following technical solutions: a kind of semi-round ball film automatic liquid-stopping transfusion apparatus, comprise tube for transfusion, perforator, dropping funnel, flow regulator, female Luer and transfusion needle, in described dropping funnel, be provided with a hemisphere automatic liquid-stopping device, this hemisphere automatic liquid-stopping device comprises the buoyancy aid being arranged in dropping funnel; Described buoyancy aid inside is a cavity structure, and upper end is closed, lower ending opening; The upper side of described buoyancy aid was vertically distributed with tank with it, and the lower side of buoyancy aid is provided with a plurality of inlet openings with it; Port, described buoyancy aid lower end is arranged with a semi-round ball film, described semi-round ball film adopts flexible film material to make, the inner water outlet of described dropping funnel is provided with one and can coordinates the taper projection that snaps in described buoyancy aid lower end, and described taper projection is provided with a drainage hole.
The upper end of described buoyancy aid is provided with a water inlet gross porosity, and in cavity structure, is provided with a transverse slat, is also provided with a water outlet micropore on described transverse slat.
Described tube for transfusion adopts two-layer pipe, and wherein, inner tube does not adopt and makes containing DEHP plasticizer material, and outer tube adopts PVC material to make.
Compared with prior art, the semi-round ball membrane structure that this utility model adopts can be when transfusion will finish, block the drainage hole on taper projection, medicinal liquid in dropping funnel cannot be continued dirty, the medicinal liquid in buoyancy aid is slowly dirty simultaneously, keep liquid level pressure balance, stopped up hill and dale " blood back " phenomenon, and total is simple, is easy to realize, practical, be worth significantly promoting.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of dropping funnel of the present utility model and buoyancy aid.
The specific embodiment
Below in conjunction with drawings and Examples, utility model is described in detail.
As shown in Figure 1, 2, the semi-round ball film automatic liquid-stopping transfusion apparatus the utility model proposes, comprise tube for transfusion 1, perforator 2, dropping funnel 3, flow regulator 4, female Luer 5 and transfusion needle 9, in dropping funnel 3, be provided with a hemisphere automatic liquid-stopping device, this hemisphere automatic liquid-stopping device comprises the buoyancy aid 6 being arranged in dropping funnel 3; Buoyancy aid inside is a cavity structure, and upper end is closed, lower ending opening; The upper side of buoyancy aid was vertically distributed with tank 61 with it, and the lower side of buoyancy aid is provided with a plurality of inlet openings 62 with it; Buoyancy aid 6 ports, lower end are arranged with a semi-round ball film 7, and semi-round ball film 7 adopts flexible film material to make, and the inner water outlet of dropping funnel 3 is provided with one can coordinate the taper projection 8 that snaps 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 in cavity structure, is provided with a transverse slat 64, is also provided with a water outlet micropore 65 on transverse slat.Tube for transfusion 1 is bimetallic tube, and wherein, inner tube does not adopt and makes containing DEHP plasticizer material, and outer tube adopts PVC material to make.
In an embodiment of the present utility model, in dropping funnel, be also provided with a cutting ferrule 10, cutting ferrule 10 is an empty frame shape, be fastened in the top of buoyancy aid 6, when buoyancy aid rises, buoyancy aid is spacing at certain liquid level, prevent that buoyancy aid is when liquid level falls after rise, by dropping funnel medial wall seam, blocked.
When infusing, medicinal liquid enters dropping funnel 3, medicinal liquid flows through from the tank of crossing of buoyancy aid 6, and buoyancy aid produces buoyancy and rises in dropping funnel 3 inner liquid medicines, medicinal liquid in dropping funnel 3 also can enter in buoyancy aid 6 from water inlet gross porosity 63 and inlet opening 62, from drainage hole 81, flow out, now in the cavity of buoyancy aid, be full of medicinal liquid, semi-round ball film 7 is the state of heaving, when transfusion will finish, the liquid level of dropping funnel 3 declines, buoyancy aid 6 slowly sinks, while reaching the height of certain whereabouts, taper projection 8 withstands semi-round ball film 7, semi-round ball film 7 is flat to be entered and has blocked drainage hole 81, in the time of in taper projection 8 pushes into buoyancy aid lower end completely, taper projection 8 by buoyancy aid cavity inner horizontal plate the medicinal liquid below 64 from inlet opening, 62 extrude, and now, more than 64 be stored in advance in cavity at transverse slat on, medicinal liquid water outlet micropore 65 oozes, from inlet opening, 62 flow out in dropping funnel again, so just formed a water-stop, the pressure balance that keeps liquid level, thereby thoroughly stopped " blood back " phenomenon.
Above-described embodiment has only been expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, this utility model patent and protection domain should be as the criterion with appended claims.
