Abstract

The invention discloses an infusion speed regulating device. The infusion speed regulating device comprises a shell, an adjusting wheel, a connecting rod, and a compression spring, wherein one end ofthe connecting rod is connected with the middle of the adjusting wheel, and the other end of the connecting rod is provided with a first sliding block cooperating with a first sliding groove; the compression spring is located opposite to the connecting rod, one end of the compression spring is connected with the middle of the adjusting wheel, a connecting block is arranged at the other end of thecompression spring, and a pressing block is arranged on the other side of the connecting block; and the pressing block is abutted against the side wall of the shell under the action of the compressionspring, and then the position of the adjusting wheel is locked. The infusion device is characterized in that the infusion speed regulating device is arranged on an infusion tube. The device has the beneficial effects that the position of the adjusting wheel can be locked, and movement is avoided.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an infusion speed regulating device and an infusion device thereof. Background technique [0002] Intravenous infusion is a method of injecting a large amount of sterile liquid, electrolytes, and drugs into the body through the vein using the principles of atmospheric pressure and hydrostatic pressure. Injecting large amounts of fluids, electrolytes, or blood into a vein is called intravenous infusion. Depending on the site of injection and infusion, it can be divided into peripheral venous infusion, central venous infusion, high nutrition infusion (TPN) and blood transfusion. [0003] The existing infusion device has the following defects: first, during the infusion process, the adjustment wheel is prone to displacement, resulting in a change in the drip rate, which makes the patient uncomfortable; second, the infusion bag needs to be hung on the bracket all the time, which is ...
