Problems solved by technology

[0006] Although the above-mentioned structure has anti-bubble effect, secondary bubbles will be generated indefinitely. After the bubbles are generated, they cannot be automatically separated or removed. It is still necessary to remove them from the lower end or perform manual secondary exhaust. The effect is not ideal.

Abstract

The invention relates to a self-venting bubble-free infusion set, which comprises a body comprising a venting tube connected with a lower catheter and a buffer body arranged in a dipper. The upper and lower ends of the venting tube are communicated; at least one venting groove is formed on a middle part of a side wall of the venting tube; the upper part of the venting tube is connected with the buffer body; the buffer body comprises a buffer surface and a handle connected with the buffer surface, wherein the handle has a hollow structure and is sealed on a part close to the buffer surface; and a circular air vent is formed at the lower end of the handle close to the sealed part. The self-venting bubble-free infusion set has the advantages that: automatic venting is realized through only one bottle inserting action during infusion, bubbles are not generated, and the infusion set is easy to operate and safe and reliable.

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] At present, there is no big difference in the disposable infusion set products generally used at home and abroad, all of which are made up of a cork puncturer, a drip funnel, a catheter, a regulator, a filter, and an intravenous infusion needle. During clinical use, at the beginning of the infusion, after inserting the cork piercer into the infusion bottle, the dropping funnel needs to be turned upside down, and turned upside down after the liquid reaches a certain height, so as to prevent air bubbles from occurring. However, this operation is cumbersome and time-consuming. If there is a slight carelessness or other reasons, a large number of air bubbles will be generated. After the air bubbles are generated, the nursing staff need to squeeze or pinch the air bubbles to get rid of them. In most of the a...
