Embodiment Construction

[0011] The invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0012] like figure 1 , 2 As shown in the figure, the precision automatic liquid stopper and anti-return blood infusion set proposed by the present invention includes an infusion tube 1 and a flow regulator 2 sleeved on the infusion tube. The infusion tube 1 is also connected with a puncture device 3, a drip bucket 4, a luer The joint 5 and the infusion needle 6, compared with the traditional technology, the improvement of the present invention is that the drip hopper 4 is provided with an automatic liquid stop valve. The automatic liquid stop valve includes a valve body 7 and an automatic liquid stop layer 8. The valve body 7 is installed on the The lower part of the drip bucket 4, and the valve wall of the valve body 7 is provided with a circle of strip-shaped openings 71 for dripping circulation, and the bottom of the valve body 7 is also provided with a cyl...

Abstract

The invention discloses a precise automatic liquid-stopping blood-return-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 an automatic liquid-stopping valve is arranged in the drip bucket and a precise filtering film is used for automatically stopping liquid. 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 by an anti-reflux valve; 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 precise automatic liquid stopper and blood-return prevention infusion set. Background technique [0002] At present, the single-use infusion set used for medical infusion liquid, if the blood will flow back after the liquid infusion, it is dangerous to not exhaust the gas when changing the bottle, but it is very troublesome to exhaust the gas. Some infusion sets are equipped with various types of self-closing valves at the mouth of the drip bucket. Although the liquid can be automatically closed after the liquid is infused, it is difficult to change the bottle and open the valve, 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 fluid is infused frequently, particles with a diameter of more than 4 μm in the medicinal solution will accumulate in the capillaries of the heart, liver, lung, ...
