Abstract
The utility model discloses a floating piece type automatic stagnation flow burette infusion apparatus, which comprises a medicine bag puncture needle communicated with a tube body, wherein the lower part of the tube body is communicated with a burette which is communicated with an intravenous infusion needle; a lower cover of a cylinder body is arranged at the bottom of the tube body and is provided with a communicating pipeline communicated with the burette; a lug boss is formed by the part of the communicating pipeline, which is positioned at the part in the tube body; and a floating piece for closing the communicating pipeline is arranged in the tube body. By matching the floating piece with the communicating pipeline on the lower cover of the tube body, the floating piece floats on the liquid level when the liquid level in the tube body is higher; and when the liquid flows out, due to the actuating force of the liquid, the automatic closing and the stagnation flow can be realized; and in addition, the utility model can prevent air from entering the human body and prevent an air bolt from forming to avoid the risk.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, is specifically related to a kind of floating chip automatic flow-stop burette transfusion device.
Background technology
Existing titration tubular type transfusion device, though in use can be from defeated, can not be when transfusion be finished automatic flow-stop, when the medicinal liquid in dropper flows to end, if unmanned nursing in front of the patient just has a large amount of gas and is full of transfusion device, even enter in the venous patient, cause air embolus; Or in venous blood adverse current syringe needle and the tube for transfusion, solidify the back and block syringe needle, if transfusion just need be done venipuncture again again, both increased patient's misery, when having increased nursing staff's workload, particularly critical patient or infantile infusion again, cause danger easily.
The utility model content
The technical problems to be solved in the utility model is the deficiency at technique scheme, provides to prevent the air admission human body, forms a kind of floating chip automatic flow-stop burette transfusion device of air embolus.
For addressing the above problem the technical solution of the utility model be:
A kind of floating chip automatic flow-stop burette transfusion device, comprise the medicated bag puncture needle, the medicated bag puncture needle is communicated with body, the bottom of body is communicated with burette, burette is communicated with venoclysis needle, it is characterized in that: the bottom of described body has the cylindrical shell lower cover, covers under the described cylindrical shell to have the connecting pipe that is communicated with burette, described connecting pipe is positioned at the intravital part of pipe and forms boss, and having in the described body can be with the floating sheet of connecting pipe sealing.
Below be to further improvement in the technical proposal:
Described floating sheet comprises disk portion, and the periphery of described disk portion has annulus portion, and the thickness of annulus portion is greater than the thickness of disk portion.
Be provided with infusion tube between burette and the venoclysis needle, described infusion tube is provided with filter and actuator.
This utility model adopts cooperating of the connecting pipe that covers under floating sheet and the cylindrical shell, and when liquid level was high in the body, floating sheet floated on the liquid level, when liquid flows to end, because the suction-combining force of liquid is realized automatic airtight and fluid stopping, to stop the further decline of liquid level, when infusing once more, actuator to cut out, medicinal liquid is to after good, the extruding dropping funnel promptly can float floating sheet, infuse once more, use this utility model can prevent the air admission human body, avoided the formation air embolus to cause danger.
Below in conjunction with drawings and Examples technique scheme is described further.
Description of drawings
Accompanying drawing 1 is the structural representation of floating chip automatic flow-stop burette transfusion device among this utility model embodiment;
Accompanying drawing 2 is the partial enlarged view of I part in the accompanying drawing 1;
Accompanying drawing 3 is the structural representation of floating sheet among this utility model embodiment.
Among the figure: 1-medicated bag puncture needle; The 2-body; 3-floats sheet; 4-cylindrical shell lower cover; The 5-burette; The 6-infusion tube; The 7-actuator; The 8-filter; The 9-venoclysis needle; The 10-boss; 11-disk portion; 12-annulus portion; The 13-connecting pipe; 14-titration pin.
The specific embodiment
Embodiment, as shown in Figures 1 and 2, a kind of floating chip automatic flow-stop burette transfusion device, comprise medicated bag puncture needle 1, medicated bag puncture needle 1 is communicated with body 2, the bottom of body 2 is communicated with burette 5, burette 5 is communicated with venoclysis needle 9, be provided with infusion tube 6 between burette 5 and the venoclysis needle 9, described infusion tube 6 is provided with filter 8 and actuator 7, the bottom of described body 2 has cylindrical shell lower cover 4, has the connecting pipe 13 that is communicated with burette 5 on the described cylindrical shell lower cover 4, and the part that described connecting pipe 13 is positioned at body 2 forms boss 10, the end that described connecting pipe 13 is positioned at burette 5 is provided with titration pin 14, having in the described body 2 can be with the floating sheet 3 of connecting pipe 13 sealings, and described floating sheet 3 is made for non-toxic plastic, as shown in Figure 3, described floating sheet 3 comprises disk portion 11, the periphery of described disk portion 11 has annulus portion 12, and the thickness of annulus portion 12 is greater than the thickness of disk portion 11, and the diameter of described floating sheet 3 is less than the internal diameter of body 2.
This utility model adopts cooperating of connecting pipe 10 on floating sheet 3 and the cylindrical shell lower cover 4, when liquid level is high in the body 2, floating sheet 3 floats on the liquid level, when liquid flows to end, because the suction-combining force of liquid is realized automatic airtight and fluid stopping, begin transfusion after opening actuator 7, when liquid flows to end, floating sheet 3 falls and cylindrical shell lower cover 4 closures, because the suction-combining force of liquid is realized automatic airtight and fluid stopping, to stop the further decline of liquid level, when infusing once more, actuator to cut out, medicinal liquid is to after good, extruding dropping funnel 5 promptly can float floating sheet 3, infuse once more, the simple and practical convenience of this utility model prevents the air admission human body, prevent to form air embolus, result of use is good.
