Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an infusion controller for preventing a patient from adjusting the number of drops. Background Art

[0002] At present, the medical infusion devices used in the market are generally composed of an infusion bottle and an infusion needle connected to the infusion bottle. An infusion observation tube is provided at the front end of the infusion needle to facilitate observation of the dripping rate of the droplets. The rear end of the infusion observation tube is connected to the infusion tube, and the other end of the infusion tube is connected to the needle capillary. In order to control the dripping rate, an adjustment slider is generally placed on the infusion tube. By sliding the slider, the cross-sectional area of ​​the infusion hose is changed to achieve the purpose of controlling the infusion speed.

[0003] Normally, patients with heart disease should limit the infusion to 20-30 drops per minute. If they have heart failure, the infusion should be limited to no more than 20 drops per minute. If the infusion rate is too fast and the preload suddenly increases in a short period of time, the risk of heart failure will increase, leading to acute pulmonary edema and even acute left heart failure.

[0004] An adjustable slider is used to control the liquid dripping rate. During operation, the slider is easily affected by external forces and may accidentally slide, resulting in inaccurate dripping rate. At the same time, different types of drugs have different degrees of stimulation to blood vessels, and therefore have different requirements for infusion time. If the patient blindly adjusts the infusion speed, it will affect the treatment effect. Utility Model Content
