Background technique

Microinjection pump (micropump for short) can pump a small amount of medicinal liquid into the patient's body accurately, evenly and continuously, so that the drug can maintain effective blood concentration in the body to rescue critically ill patients. It is often used in ICU critically ill patients, cardiovascular and cerebrovascular diseases For patient rescue, when the patient needs micro-pumping of multiple drugs, the currently commonly used clinical infusion connectors are one-way valve infusion connectors (horizontal five-way plate) and three-way connections, but there are the following problems:

1. The distance between each connector is too close to facilitate disinfection;

2. The distance between each interface and the patient is inconsistent. Especially when the patient uses vasoactive drugs, due to the distance problem, there is a gap in the time when the drug liquid enters the patient's body, which will cause the patient's blood pressure to fluctuate.

3. Since patients need to inject a variety of different medicinal solutions, when there are many infusion tubes, it is easy to get confused, and in serious cases, injection errors may occur.

4. Multiple pipelines are used at the same time, which is too messy and easily confused or entangled.

In response to the above situation, it is necessary to develop a new one-way valve infusion connector for micro-pumps to meet the needs.

Detailed ways

The present utility model will be further clarified below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present utility model and are not intended to limit the scope of the present utility model.

As shown in the figure, the utility model describes a new one-way valve infusion connector for a micropump, which includes a disk 1, an infusion set 2, and an anti-reflux infusion connector 3.

The disc 1 is a hollow disc, a collecting tube 4 is provided at the center of the disc, and a connecting hole 5 is provided on the side of the collecting tube 4;

The number of the anti-reflux infusion connectors 3 is 4-8 (preferably 6), and the 4-8 anti-reflux infusion connectors 3 are evenly arranged on the side of the disk 1, and the anti-reflux infusion connectors 3 pass through The internal channel 6 is connected to the connecting hole 5 (the internal channel 6 is a hard plastic tube, one end is connected to the anti-reflux infusion connector 3, and the other end is connected to the connecting hole 5);

The infusion set 2 (that is, the infusion hose) passes through the disc transversely, and the middle of the infusion set 2 is also connected to the connecting hole. The two ends of the infusion set are exposed outside the disc to form an inlet end 11 and an outlet end 12. The inlet end The end of 11 is connected to the anti-reflux infusion connector 13 of the infusion set, and the tail of the outlet end 12 is provided with a card connector 7 .
