Abstract

The invention relates to a bubble-proof transfusion device, comprising a dripping pipe (1), a dripping bucket (2), medical liquid (3), a bubble proof pipe (40) and a duct (5); wherein the bubble-proofpipe (40) is sealed at the upper part and provided with at least two notches (41) at a cylindrical side. The invention has the advantages that bubble in the medical liquid is prevented from enteringthe duct, degassing operation time during clinic transfusion is greatly shortened, and the transfusion speed during transfusion requiring a large amount can be enhanced due to vacuum negative pressurein the pipe as designed, thereby meeting the clinic first-aid effect.

Description

technical field

[0001] The invention relates to an infusion set, in particular to an anti-bubble tube in a dropping funnel in the infusion set. Background technique

[0002] A single-use infusion set is a product used by patients for infusion in medical care.

[0003] Depend on figure 1 It can be seen that the infusion set is composed of a dropper 1, a drip funnel 2, a medicinal solution 3, an anti-bubble tube 4, and a catheter 5; wherein the anti-bubble tube 4 communicates with the catheter 5, and the catheter 5 is connected with the infusion needle (not shown in the figure).

[0004] Depend on figure 2 It can be seen that the anti-bubble tube 4 is a cylindrical tube with an upper opening. In order to solve the purpose of anti-bubble, artificial exhaust must be carried out: first hang the drip funnel upside down, and after the liquid passes through the nozzle of the anti-bubble tube, hang the drip funnel upright to achieve the purpose of anti-bubble. Great inconvenienc...

Embodiment Construction

[0014] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0015] Depend on image 3 , Figure 4 , Figure 5 It can be seen that the present invention includes: dropper 1, drip funnel 2, medicinal liquid 3, anti-bubble tube 40, catheter 5; 41 above the notch.

[0016] The number of at least two notches 41 is three.

[0017] The operation of the present invention is basically the same as that of a common infusion set, but no manual exhaust is required, and the exhaust time is no more than 10 seconds (generally more than 30 seconds for common tubes). Its working principle is that when the air bubbles in the liquid flow through the narrow slit of the anti-bubble tube, they are blocked outside the anti-bubble tube due to the surface tension of the bubbles, and cannot continue to flow into the infusion line.

[0018] The present invention utilizes the surface tension of liquid and gas and the kinetic pr...
