Description

A connection device for an infusion set and an infusion bottle

technical field

The utility model relates to the technical field of medical devices, in particular to a connecting device for an infusion set and an infusion bottle.

Background technique

Infusion, also known as drip or hanging water, is a large-dose injection that is injected into the body by intravenous drip, and the dose is more than 100ml at a time. Usually packaged in glass or plastic infusion bottles or bags, it contains no preservatives or bacteriostatic agents. When using, adjust the drip rate through the infusion set, and enter the vein continuously and steadily to replenish body fluids, electrolytes or provide nutrients. The development of intravenous infusion technology has experienced twists and turns for nearly 500 years, and gradually formed a complete system in the 20th century, becoming one of the most commonly used and most direct and effective clinical treatment methods.

The infusion set is mainly used for the sterile treatment of intravenous infusion, a common disposable medical consumable that establishes a channel between the vein and the medicinal liquid, and is widely used in the medical field. During infusion, one end of the infusion set is punctured into the infusion bottle, and the other end of the infusion set is used for intravenous injection. The infusion tube will inevitably be pulled during the infusion, especially children who often pull the infusion tube, which will cause the infusion set. The end punctured into the infusion bottle is disengaged from the infusion bottle, thereby affecting the normal infusion. Once the infusion tube is disconnected, it will be contaminated, and it needs to be replaced with a new infusion tube, causing unnecessary waste. Some patients even privately puncture the infusion set into the infusion bottle again, which will lead to drug contamination, which will seriously affect the patient's health after the contaminated drug is infused into the patient's body.

SUMMARY OF THE INVENTION

The purpose of the utility model is to provide a connecting device of an infusion set and an infusion bottle, which is connected to the bottle mouth of the infusion bottle and the bottle stopper piercer of the infusion set to prevent the two from being separated.

The connecting device adopts a two-part pluggable structure, and the distance between the inserting ring and the adjusting ring can be adjusted to a certain extent, so as to cope with the cork piercers of different lengths.

Preferably, the insertion rod is perpendicular to the insertion tape.

Preferably, the insertion rod and the insertion tape are located on the same straight line.

Preferably, teeth are provided on both sides of the inserting belt, and the inserting ring is a square ring. Compared with the single-sided toothed plug, it is more convenient to plug and pull, and the fixing effect is better.

Compared with the prior art, the beneficial effects of the present utility model are: 1. The adjusting ring and the adjusting buckle are respectively sleeved on the bottle mouth of the infusion bottle and the cork piercer of the infusion set, and the two are fixed to avoid the bottle stopper. The trocar falls off, which reduces the workload of nurses for changing the infusion set and the risk of fluid contamination, and at the same time avoids waste of medicinal fluid in the infusion tube.

2. Both the adjustment ring and the adjustment buckle are adjustable, which can be adjusted according to the size of the bottle mouth or the diameter of the infusion set.

3. The connecting device can be used repeatedly, avoiding the phenomenon that the existing adjustable cable ties need to be cut off and discarded after being bound, thereby saving resources.
