Abstract
Infusion apparatus with IV fluid automatically infusing and stopping and air automatically draining comprises a drip chamber (1), a mesh enclosure (2), a floater (3) and an air-in cover (4). A sealing film (3-1) is placed on the bottom of the floater (3) which is arranged inside the mesh enclosure (2). An air exhaust opening (1-4) is formed in the side wall of the drip chamber (1), and an air filtering film (5) is placed on the air exhaust opening (1-4). The air-in cover (4) is provided with a hole, is placed on the air exhaust opening (1-4) of the drip chamber (1) and is attached to the air filtering film (5). The infusion apparatus has the advantages of automatically infusing IV fluid without squeezing, and automatically stopping infusing the IV fluid when infusion is finished. The air exhaust opening in the drip chamber can automatically drain liquid bubbles in the drip chamber out, inconvenience brought in the process of using is prevented, and potential safety hazard is reduced.

Technical field
The present invention relates to field of medical appliances, be specifically related to a kind of automatic lower liquid, automatic liquid-stopping and Automatic-exhaust transfusion system.
Background technology
At present, in medicine and hygiene fields, usually adopt disposable infusion set to carry out venous transfusion to the patient.And there is following defective in existing general infusion set:
1, in infusion process, the workload of health care worker is very large, a medical worker often needs to look after the multidigit transfusion patient, after completing, each transfusion patient transfusion all in time dispose, in time do not dispose, can cause the interior air of transfusion device to enter patient's blood vessel or patient blood refluence, have potential safety hazard.
2, the medical worker need to repeatedly push dropping funnel when medicinal liquid is introduced transfusion device, need to waste time and energy, and also easily produces and bubble in medicinal liquid, and bubble enters blood with medicinal liquid, has potential safety hazard.
Summary of the invention
Purpose of the present invention is exactly for the above-mentioned deficiency of present existing transfusion device, and provide a kind of automatic lower liquid, the transfusion complete after automatic liquid-stopping and Automatic-exhaust transfusion system.
This utility model comprises dropping funnel, the dropping funnel two ends have dropper interface and drain pipe interface, it also has guard, float and Intake Cover, be provided with bank of annular bottom the inwall of dropping funnel, the guard bottom is provided with down card, the annular that is installed on dropping funnel of guard is fallen on bank, the float bottom is provided with diaphragm seal, float is placed in guard, and is positioned at the drain pipe interface top of dropping funnel, has air vent on the sidewall of dropping funnel, air vent is provided with air-filtering membrane, have the hole on Intake Cover, Intake Cover is arranged on the air vent of dropping funnel, and is fitted on air-filtering membrane.
Dropping funnel is fabricated structure, dropping funnel is comprised of liquid pipe, upper cover and lower cover, upper cover and under cover and be respectively equipped with dropper interface and drain pipe interface, on cover and be provided with draw-in groove, liquid Guan Yiduan is positioned at the draw-in groove of upper cover, under cover and be provided with annular and fall bank, lower cover is arranged on the liquid pipe other end, and the annular of lower cover is fallen bank and is positioned at the liquid pipe, the annular that is installed on lower cover of guard is fallen on bank, and float is placed in guard, and is positioned at the drain pipe interface top of lower cover, have air vent on the sidewall of liquid pipe, Intake Cover is arranged on the air vent of dropping funnel.
The utility model has the advantages that: this infusion set need not to push dropping funnel automatically descend liquid, transfusion to complete after the automatic liquid-stopping function, the air vent on dropping funnel can be discharged liquid bubble in dropping funnel automatically, prevents the inconvenience that brings in use procedure, reduces potential safety hazard.
