Embodiment Construction
[0011] The invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0012] Such as figure 1 As shown, the precision automatic anti-liquid infusion device proposed by the present invention includes an infusion tube 1 and a flow regulator 2 sleeved on the infusion tube. Connector 5 and infusion needle 6, the water outlet in dripping funnel 4 protrudes upwards a diversion tube 7, and the tube wall of diversion tube 7 is provided with a row of openings 71 for the inflow of dripping liquid, and the nozzle upper cover of diversion tube 7 There is an anti-bubble valve 8, the anti-bubble valve includes a tube cover 81 and a valve body 82 protruding from the bottom of the tube cover 81 to match and insert into the guide tube 7, and a pair of valve bodies corresponding to the opening 71 are provided on the valve wall of the valve body 82. Hook 83.
[0013] The top of the guide tube 7 is also provided with an automatic liquid-stopping...

The invention discloses a precise automatic liquid-stopping air-bubble-proof infusion device which comprises an infusion tube, a flow adjuster, a puncture device, a drip bucket, a Luer taper and an infusion needle, wherein a flow guide tube used for preventing liquid drops from falling and forming air bubbles is arranged in the drip bucket; an air-bubble-proof valve is mounted on the flow guide tube; an automatic liquid-stopping layer is arranged in the drip bucket; a precise filtering film is used for automatically stopping liquid. During an infusion process, the precise automatic liquid-stopping air-bubble-proof infusion device can prevent the liquid drops from forming the air bubbles in the drip bucket; when the liquid is completely infused, the liquid can be automatically stopped under the effect of the hydrophily of the precise filtering film; the negative phenomenon, such as blood return, is avoided; the safety during the infusion process is ensured.
Description
technical field [0001] The invention relates to the field of medical devices, in particular to a precision automatic liquid-stopping and bubble-proof infusion set. Background technique [0002] At present, the medical disposable infusion set used for infusion, such as the blood will flow back when the liquid is infused, and it is dangerous not to vent the gas when changing the bottle, but it is very troublesome to exhaust the gas. Some infusion sets are equipped with self-closing valves of various styles at the mouth of the drip funnel. Although the liquid preservation can be automatically closed after the liquid medicine has been transfused, it is difficult to open the valve when changing bottles, and the operation is troublesome. The average diameter of capillaries in the human body is only 7 μm to 9 μm, and the smallest is 4 μm. If the liquid is infused frequently, particles with a diameter exceeding 4 μm in the liquid medicine will accumulate in capillaries such as the ...
