Hanging-free scale speed regulation pressure infusion bracelet based on grating sensor

Abstract

The invention relates to a hanging-free scale speed regulation pressure infusion bracelet based on a grating sensor. The hanging-free scale speed regulation pressure infusion bracelet comprises an annular bottle capable of being worn on an arm, wherein the middle of the annular bottle is broken to form a mounting gap, a left blocking plate and a right blocking plate are arranged on the left side and the right side of the mounting gap of the annular bottle respectively, a liquid inlet pipe is connected to the left side of the annular bottle, a liquid inlet valve is arranged on the liquid inlet pipe, and an infusion tube is connected to the left side of the annular bottle; and a manual speed regulator is arranged on the infusion tube, a piston is arranged in the annular bottle in a sliding and sealing mode, and a power device used for driving the piston to move in the annular bottle is arranged in the mounting gap. The hanging-free scale speed regulation pressure infusion bracelet has great portability in the injection period of a patient, a threshold value is set in each microprocessor, when liquid in the annular infusion bottle is less than the preset threshold value, an alarm is given to remind the patient and a nurse to replace medicines in time, and the medical problems that the patient is inconvenient to move in the infusion period, and timely accompanying of nurses and family members is not realized, are solved, and the high efficiency of the infusion progress and the working efficiency of hospitals are greatly improved.

Description

technical field [0001] The invention belongs to the field of medical equipment machinery, and in particular relates to a free-hanging scale speed-regulating pressure infusion wristband based on a grating sensor. Background technique [0002] Infusion is one of the most common medical methods. There are a large number of patients who need infusion in every hospital. Traditional infusion bottles or infusion bags need to be hung on the infusion stand to infuse patients. Patients can only lie on the bed or It is extremely inconvenient to sit on the bed and wait for the medicine to be infused. It needs to be accompanied by family members and nursing staff at any time. The number of doctors and patients in the hospital is relatively small, and the number of nurses is relatively small, so the overall work efficiency is not high. In addition, because the long-term infusion leads to mental fatigue of the patient, it is necessary to monitor the progress of the infusion from time to ti...

Problems solved by technology

Although this technique is simple, the elastic element needs to be in direct contact with the drug liquid, which may contaminate the infused liquid, thereby endangering the health of the patient. At the same time, the pressure sensing infusion instrument is also limited by the interference of external factors, and a slight movement of the patient will cause The elastic element misjudged the drop of water and issued an alarm, with a high error rate

[0006] The above three infusion technologies all have technical loopholes, the safety of patients is difficult to guarantee, and it is difficult to promote and further improve in the market
