Description
Technical field
This utility model relates to a kind of Anti-bubble buoyancy aid and stops drop bucket and transfusion device, belongs to medical instruments field.
Background technology
In recent years, for preventing that clinical transfusion medicinal liquid drips the problem of the Ink vessel transfusing air inlet that sky causes, occur that many float valve classes stop liquid transfusion device, as Chinese patent CN202478324U (transfusion device), propose in ZL200580030194.9 (disposable safe transfusion system) and drive sealed film shutoff pipeline to intercept the mode of medicinal liquid or gas by buoyancy aid, but the details do not coordinated with buoyancy aid with regard to sealed film is done to design further, and in Clinical practice, the improper meeting of assembling of the two causes the depressed area of (i.e. sealed film) vertical direction bottom buoyancy aid, be unfavorable for the discharge of bubble.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of and can prevent the accumulation of buoyancy aid bubble, promote that the Anti-bubble buoyancy aid that bubble discharges buoyancy aid stops drop bucket, provide a kind of simultaneously and have the transfusion device that this Anti-bubble buoyancy aid stops drop bucket.
Anti-bubble buoyancy aid described in the utility model stops drop bucket, buoyancy aid is provided with in dropping funnel body, the bottom fixing seal film of buoyancy aid, the outer rim of sealed film is thick, intermediate thin, in the side towards dropping funnel liquid outlet, the peripheral edge portion of sealed film is higher than mid portion, the dropping funnel liquid outlet of dropping funnel body bottom portion extends to form protruding fluid structure to dropping funnel inner chamber side, the peripheral dimension of protruding fluid structure upper end is not more than the diameter of the mid portion of sealed film, is provided with transition chamfering between the mid portion of sealed film and peripheral edge portion.
When (after namely the intrinsic medicinal liquid of dropping funnel all flows out) after medicinal liquid infusion-completed, buoyancy aid can fall to the bottom of dropping funnel body automatically, sealed film bottom buoyancy aid is by the protruding fluid sealing structure of dropping funnel body bottom portion, guarantee to enter infusion pipeline below whole dropping funnel without air, thus ensure the safety of patient; Transition chamfering between the mid portion of sealed film and peripheral edge portion, can make buoyancy aid undercut place bubble discharge along transition chamfering direction, thus the bubble under preventing buoyancy aid accumulates, and is conducive to the bleeding before transfusion operation, easy to use.
Preferably, by back-off, sealed film is fixed bottom buoyancy aid.When the lower surface of the peripheral edge portion of sealed film position lower than back-off lower surface or concordant with the lower surface of back-off time, this transition chamfering can cover the back-off bottom sealed film and buoyancy aid, be a complete transition chamfering, thus be conducive to the discharge of buoyancy aid undercut place bubble; When lower surface higher than back-off of the position of the lower surface of the peripheral edge portion of sealed film, this transition chamfering cannot cover back-off, now sealed film peripheral edge portion may and back-off between have step, discharge more easily for the ease of bubble, make back-off to possess the second chamfering, seamlessly transit between second chamfering and transition chamfering, form a complete transition chamfering, thus be conducive to the discharge of buoyancy aid undercut place bubble.
Preferably, the position limiting structure of restriction buoyancy aid floating height is provided with in dropping funnel body.
Preferably, sealed film, buoyancy aid carry out hydrophilic process.
Transfusion device described in the utility model, comprises dropping funnel, and described dropping funnel adopts above-mentioned Anti-bubble buoyancy aid to stop drop bucket.
The beneficial effect that this utility model is compared with prior art had is:
This Anti-bubble float valve stops drop bucket structure advantages of simple, by the setting of buoyancy aid and sealed film transition chamfering, effectively can promote the discharge of buoyancy aid undercut place bubble, be conducive to the bleeding before transfusion operation, easy to use; The transfusion device adopting Anti-bubble float valve to stop drop bucket has the equivalent technology effect that this Anti-bubble float valve stops drop bucket.

Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Fig. 1 ~ 5, Anti-bubble buoyancy aid described in the utility model stops drop bucket, comprise dropping funnel body 1, buoyancy aid 4 is provided with in dropping funnel body 1, the bottom fixing seal film 5 of buoyancy aid 4, the outer rim of sealed film 5 is thick, intermediate thin, in the side towards dropping funnel liquid outlet 7, the peripheral edge portion 9 of sealed film 5 is higher than mid portion 8, dropping funnel liquid outlet 7 bottom dropping funnel body 1 extends to form protruding fluid structure 6 to dropping funnel inner chamber 2 side, the peripheral dimension of protruding fluid structure 6 upper end is not more than the diameter of the mid portion 8 of sealed film 5, transition chamfering 11 is provided with between the mid portion 8 of sealed film 5 and peripheral edge portion 9, this transition chamfering 11 can make buoyancy aid 4 undercut place bubble discharge along transition chamfering 11 direction, thus prevent the bubble under buoyancy aid 4 from accumulating, be conducive to the bleeding before transfusion operation, easy to use.In the present embodiment, in dropping funnel body 1, be provided with the position limiting structure 3 of restriction buoyancy aid 4 floating height; Sealed film 5 is fixed to projecting inward back-off 10 by level bottom buoyancy aid 4; Sealed film 5, buoyancy aid 4 all carry out hydrophilic process.
For coordinating of buoyancy aid 4 and sealed film 5, in this utility model, provide following two schemes (but being not limited to following two schemes):
Scheme one:
The position of the lower surface of the peripheral edge portion 9 of sealed film 5 is lower than the lower surface of back-off 10 or concordant with the lower surface of back-off 10, as shown in Figure 2 and Figure 3, now, transition chamfering 11 between the mid portion 8 of sealed film 5 and peripheral edge portion 9 can cover the back-off 10 bottom sealed film 5 and buoyancy aid 4, therefore this transition chamfering 11 is complete transition chamferings, thus is conducive to the discharge of buoyancy aid 4 undercut place bubble.
Scheme two:
The position of the lower surface of the peripheral edge portion 9 of sealed film 5 is higher than the lower surface of back-off 10, as shown in Figure 4, Figure 5, now, transition chamfering 11 between the mid portion 8 of sealed film 5 and peripheral edge portion 9 cannot cover back-off 10 (having step between the peripheral edge portion 9 of sealed film 5 and back-off 10), discharge more easily for the ease of bubble, make back-off 10 to possess the second chamfering 12, seamlessly transit between second chamfering 12 and transition chamfering 11, form a complete transition chamfering, thus be conducive to the discharge of buoyancy aid 4 undercut place bubble.
As shown in Figure 6; transfusion device in the present embodiment comprises protective sleeve 13, bottle plug puncture unit 14, air intake 15, dropping funnel 16 and flow regulator 18, liquid medicine filter 19, venoclysis needle 20; connected by infusion pipeline 17 between above-mentioned each parts, described dropping funnel 16 adopts above-mentioned Anti-bubble buoyancy aid to stop drop bucket.
During use, take off protective sleeve 13, bottle plug puncture unit 14 is inserted in medicinal liquid bottle or Blood bottle, liquid flows in dropping funnel 16 through infusion pipeline 17, buoyancy aid 4 floats, and then flows in the infusion pipeline 17 below dropping funnel 16, utilizes the flow velocity of flow regulator 18 scalable liquid, again through liquid medicine filter 19, flow out eventually through venoclysis needle 20; When (medicinal liquid namely in dropping funnel 16 all flows out rear) after medicinal liquid infusion-completed, buoyancy aid 4 can fall to the bottom of dropping funnel body 1 automatically, protruding fluid structure 6 bottom dropping funnel body 1 seals by the sealed film 5 bottom buoyancy aid 4, guarantee to enter infusion pipeline 17 below dropping funnel 16 without air, thus ensure the safety of patient.
