Eccentric self-air discharging drip bucket

Abstract

The invention discloses an eccentric self-air discharging drip bucket. The eccentric self-air discharging drip bucket includes a drip bucket cover, a drip bucket body, and a drip bucket base which arecoaxially arranged successively; the drip bucket cover includes a drip bucket cover body, a guide bar, a catheter seat, a dropper, and a baffle sheet; the drip bucket seat includes a drip bucket seatbody, a drainage column, and a catheter connection seat; the drainage column and the catheter connection seat are corresponding and eccentrically arranged on an upper side and a lower side of the drip bucket seat body in an one-to-one manner; the drainage column and the catheter connection seat are positioned on the same central line; and a distance between the central line of the drainage columnand the central line of the drip bucket seat body is 4-5 mm. The eccentric self-air discharging drip bucket can effectively discharge air during transfusion, the numbers of inner assemblies of the drip bucket can be minimized, the risk of micro particles and binding agent residue can be avoided, and the performance of the drip bucket is improved.

Description

technical field [0001] The invention relates to a dripping funnel for an infusion set, in particular to an eccentric self-venting dripping funnel, which belongs to the field of medical instruments. Background technique [0002] Infusion set products for automatic exhaust on the market at present, in terms of product structure, add a drainage column inside the dropping funnel, and slot the column for drainage, so that the liquid in the infusion set product is closed first during the infusion process Drainage groove, and make the liquid level reach a certain height before discharging the liquid. During this process, air bubbles cannot enter the drainage groove to avoid the formation of air bubbles in the lower end of the infusion set [0003] At the same time, the current products on the market are all designed for the drainage groove at the center of the dripping funnel. Usually, when the liquid in the dripping tube directly enters the dripping funnel, it will directly impact...

Problems solved by technology

[0003] At the same time, the current products on the market are all designed for the drainage groove at the center of the dripping funnel. Usually, when the liquid in the dripping tube directly enters the dripping funnel, it will directly impact the drainage groove. Once a drop of water enters the drainage The groove will cause air bubbles to enter the catheter of the infusion set, making the automatic exhaust invalid

Some manufacturers also design to avoid the impact of the drainage groove, and install a baffle or baffle on the top of the exhaust groove that can block the liquid from falling, which adds an accessory to the dripping funnel of the infusion set. Introduce risks such as particles and adhesive residues that may exist in product assembly, which increases the overall risk level of infusion sets
