Abstract
The utility model belongs to the field of medical apparatus and instruments and particularly relates to an automatic liquid-stop bubble-prevention infusion apparatus. The automatic liquid-stop bubble-prevention infusion apparatus comprises a bottle stopper puncture device. The bottle stopper puncture device is sheathed with a protecting jacket; the bottom part of the bottle stopper puncture device is connected with a dropping funnel, a flow regulator, a liquid medicine filter and an intravenous infusion needle in sequence through an infusion conduit; the side edge of the bottle stopper puncture device is provided with an air inlet part; a floating body is arranged in the dropping funnel; a seal rubber sheet capable of freely moving is arranged in the floating body; and the seal rubber sheet is communicated with the outside through an opening at the bottom part of the floating body. The automatic liquid-stop bubble-prevention infusion apparatus is simple and reasonable in structure. Through the floating body in the dropping funnel, liquid can be effectively and automatically prevented, and bubbles can be prevented from being brought into the infusion conduit. The automatic liquid-stop bubble-prevention infusion apparatus is safe and convenient in use and is in favor of treatment on clinical patients.
Description
Technical field
This utility model relates to a kind of automatic solution stopping bubble-proof transfusion device, belongs to medical instruments field.
Background technology
At present, hospital carries out venous transfusion or when transfusing blood, generally uses disposable transfusion device clinical patients, like this, has played useful effect to preventing the cross infection between the patient.Yet, use this disposable transfusion device also to exist weak point, promptly current disposable transfusion device is after the medicinal liquid transfusion finishes; Because of there not being the automatic-diversion closure function, the liquid bottle (bag) or pull out transfusion needle of in time changing dressings can bring unsafe factor to the patient otherwise air will get into transfusion catheter; Be unfavorable for the treatment of clinical patients; Can cause malpractice when serious, also giving originally makes troubles with regard to the nursing staff with big workload, is unfavorable for the nursing of nursing staff to clinical patients.
The utility model content
According to above deficiency of the prior art, the technical problem that this utility model will solve is: a kind of simple in structure, easy to use and safe and reliable automatic solution stopping bubble-proof transfusion device is provided.
This utility model solves the technical scheme that its technical problem adopted: described automatic solution stopping bubble-proof transfusion device; Comprise bottle plug puncture unit; Suit protective sleeve on the bottle plug puncture unit; The bottom of bottle plug puncture unit connects dropping funnel, flow regulator, liquid medicine filter and venoclysis needle successively through transfusion catheter, and the side of bottle plug puncture unit is provided with the air inlet part, it is characterized in that: be provided with buoyancy aid in the dropping funnel; The inside of buoyancy aid is provided with the sealed film that can move freely, and sealed film communicates with the external world through the opening of buoyancy aid bottom.
Described sealed film outside thickness is greater than interior thickness, and sealed film outside thickness is 2mm～5mm.Wherein, buoyancy aid bottom through rivet welding with the sealed film fixed position in buoyancy aid; Buoyancy aid and sealed film all pass through the surface hydrophilicity defoaming treatment.
This transfusion device is after the medicinal liquid transfusion finishes; After being whole outflow of medicinal liquid in the dropping funnel, buoyancy aid can fall to the bottom of dropping funnel automatically, and the sealed film of buoyancy aid bottom seals the transfusion catheter that the dropping funnel bottom connects; Guarantee not have the air admission transfusion catheter, thereby guarantee patient's safety.
For the ease of producing assembling, dropping funnel adopts following preferred version:
Described dropping funnel is combined by loam cake, dropping funnel body and base, and loam cake is installed in the upper/lower terminal of dropping funnel body respectively with base and is connected with transfusion catheter.
In order to prevent the inlet of the excessive height obstruction dropping funnel that buoyancy aid floats, stopping means is set in dropping funnel, following two kinds of preferred versions are specifically arranged:
Scheme one:
Described base top snaps in the dropping funnel body and base top has the flow of liquid port, and buoyancy aid is arranged in base, and the size of flow of liquid port is less than the buoyancy aid size.The size that can make the flow of liquid port through rivet welding in base top is less than the buoyancy aid size, thereby plays the position-limiting action to buoyancy aid.
Scheme two:
Buoyancy aid come-up limited block is set on the inwall of described dropping funnel.
The beneficial effect that this utility model had is:
Automatically solution stopping bubble-proof transfusion device is simple and reasonable for this, can effectively automatic solution stopping and prevent bubble is brought in the transfusion catheter through the buoyancy aid in the dropping funnel, and safe and convenient to use, help treatment to clinical patients.
Description of drawings
Fig. 1 is the structural representation of this utility model.
Among the figure: 1, protective sleeve; 2, bottle plug puncture unit; 3, air inlet part; 4, transfusion catheter; 5, loam cake; 6, dropping funnel body; 7, base; 8, buoyancy aid; 9, sealed film; 10, transfusion catheter; 11, flow regulator; 12, liquid medicine filter; 13, venoclysis needle.
The specific embodiment
Below in conjunction with accompanying drawing the embodiment of this utility model is done and to further describe:
As shown in Figure 1; Automatic solution stopping bubble-proof transfusion device; Comprise protective sleeve 1, bottle plug puncture unit 2, air inlet part 3, transfusion catheter 4, dropping funnel, buoyancy aid 8, transfusion catheter 10, flow regulator 11, liquid medicine filter 12 and venoclysis needle 13, dropping funnel is combined by loam cake 5, dropping funnel body 6 and base 7, and loam cake 5 is installed in the upper/lower terminal of dropping funnel body 6 respectively with base 7 and is connected with transfusion catheter 4,10 respectively; The top of base 7 snaps in the dropping funnel body 6 and base top has the flow of liquid port; Buoyancy aid 8 is arranged in base 7, and the size of flow of liquid port is less than the buoyancy aid size, but is provided with the sealed film 9 that easy on and off moves in the buoyancy aid 8; Buoyancy aid 8 bottoms through rivet welding with sealed film 9 fixed positions in buoyancy aid, sealed film 9 communicates with the external world through the opening of buoyancy aid 8 bottoms.Wherein, the size that can make the flow of liquid port through rivet welding at base 7 tops is less than the buoyancy aid size, thereby buoyancy aid 8 is played spacing effect; Buoyancy aid 8 all passes through the surface hydrophilicity defoaming treatment with sealed film 9; Sealed film 9 outside thickness are greater than interior thickness, and sealed film outside thickness is 2mm～5mm.
During use, take off protective sleeve 1, bottle plug puncture unit 2 is inserted in medicinal liquid bottle or the Blood bottle; Liquid flows in the dropping funnel through transfusion catheter 4; Buoyancy aid 8 floats, and flows into then in the transfusion catheter 10, utilizes the flow velocity of flow regulator 11 scalable liquid; Pass through liquid medicine filter 12 again, finally flow out through venoclysis needle 13.
After the medicinal liquid transfusion finished, after promptly the medicinal liquid in the dropping funnel all flowed out, buoyancy aid 8 can fall to the bottom of dropping funnel base 7 automatically, and the sealed film 9 of buoyancy aid bottom is guaranteed that transfusion catheter 10 sealings do not have in the air admission transfusion catheter 10, thereby guaranteed patient's safety.
