Background technology
Transfusion device is as conventional medical apparatus and instruments, in medical field, be widely used, usually be mainly used in venous transfusion, be a kind of common medical treatment consumptive materials, generally connected to form by bottle plug puncture unit, infusion tube, dropping funnel, air filter, liquid medicine filter, flow regulator, venoclysis needle etc.During use, under the effect of atmospheric pressure, make medicinal liquid flow into vein by transfusion device, but, because the traditional infusion device does not have safeguard procedures, such as the untimely intravenous needle that pulls out, be easy to cause the situation of blood backflow to occur after liquid is totally lost, its height hazardness has consisted of serious threat to patient's life.Although some research worker and research institution have developed transfusion device or the infusion set of some anti-backflow in succession at present, be that 200820223789.7 Chinese patent and application number are 200820223788.2 Chinese patent such as application number, all be to be provided with certain back-flow preventer in dropping funnel inside, but all there is design defect in these devices, and fail to realize safely and effectively good anti-return effect, in addition, also have some products to reach the effect of anti-return, but product structure is complicated, cost is high, production efficiency is low, is not suitable for large-scale popularization and batch production.
Summary of the invention
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of effective anti-return, disposable use backflow preventive transfusion apparatus safe, simple in structure simple to operate are provided.
The technical scheme that its technical problem that solves this utility model adopts is: this disposable use backflow preventive transfusion apparatus, comprise the air filter, bottle stopper puncture device, dropping funnel, flow regulator and the liquid medicine filter that connect by the flexible pipe order, it is characterized in that: set up the movable back-flow preventer of installing in described dropping funnel inside, back-flow preventer comprises buoy and the silicagel pad that is plugged to up and down one.In the infusion process, on the medicinal liquid plane of floatation suspension in dropping funnel of buoy because of medicinal liquid, infusion-completed relies on the gravity silicagel pad of self to contact with dropping funnel bottom arc surface, and pipeline is sealed.
The whole longitudinal section of described buoy is the font of falling the mountain, comprises top cover and plunger, and top cover is the housing that the longitudinal section is undercut shape, and plunger top is fixedly connected in the center of top cover end face.Buoy adopts two parts to peg graft and forms, and batch production is convenient in processing and the assembling of convenient scattered parts; And top cover adopts the inner structure that hollows out, and is more convenient for alleviating the weight of buoy itself, when liquid level raises, in time rises with liquid level, and is highly sensitive.
The area of described top cover horizontal top surface is greater than the bore of the inlet on dropping funnel top.
Uniform many fins that vertically arrange on the described top cover outer circle wall.The fin that evenly arranges is for increasing the component of top cover border, so that buoy can keep level floating following liquid level when floating, can steadily fall in dropping process to guarantee it, guarantees good sealing effectiveness.
Described silicagel pad integral body is inverted T-shaped, and the partial interior that top vertically arranges is provided with installing hole, and the size of installing hole matches with the size of plunger, and the area of the horizontally disposed baseplane of silicagel pad is greater than the bore of the liquid outlet of dropping funnel bottom.
Described plunger connects with the installing hole close-fitting on silicagel pad top.
Compared with prior art, the beneficial effect that has of this utility model is:
1, simple in structure, easy to use: as all to adopt the Dispoable medical plastic production, the buoy activity of setting up be installed in dropping funnel inside, the transfusion device that efficiently solves traditional structure can't be realized the safe and effective problem that prevents blood backflow, have simultaneously simple in structure, easy for operation, safe, etc. advantage, improved the safety in utilization of transfusion device, can effectively prevent and avoid blood backflow phenomenon in the infusion process, thereby reduce the difficulty of nursery work;
2, anti-return is effective, highly sensitive: buoy adopts two parts to peg graft and forms, and has realized automatic assembling, processing and the assembling of convenient scattered parts, and the part accessory can greatly be enhanced productivity and is convenient to batch production; The fin that evenly arranges is for increasing the component of top cover border, so that buoy can keep level floating following liquid level when floating, can steadily fall in dropping process to guarantee it, further guarantees good sealing effectiveness.And top cover adopts the inner structure that hollows out, and is more convenient for alleviating the weight of buoy itself, when liquid level raises, in time rises with liquid level, and is highly sensitive.
Description of drawings
Fig. 1 is this utility model front view schematic diagram.
Fig. 2 is the local amplification view of A part of this utility model Fig. 1.
Wherein: 1, bottle stopper puncture device 2, flexible pipe 3, air filter 4, dropping funnel 5, liquid outlet 6, flow regulator 7, liquid medicine filter 8, two pass joints 9, venoclysis needle 10, buoy 11, silicagel pad 12, inner arc surface 13, top cover 14, plunger 15, fin 16, inlet.
Fig. 1～2nd, most preferred embodiment of the present utility model is described further below in conjunction with 1～2 pair of this utility model of accompanying drawing.
The specific embodiment
With reference to accompanying drawing 1～2: this disposable use backflow preventive transfusion apparatus, mainly comprise the air filter 3, bottle stopper puncture device 1, dropping funnel 4, flow regulator 6, liquid medicine filter 7, two pass joints 8 and the venoclysis needle 9 that connect by flexible pipe 2 orders, set up the movable back-flow preventer of installing in described dropping funnel 4 inside.
