Non-contact medical infusion tube liquid outlet amount control method

Abstract

The invention relates to a non-contact medical infusion tube liquid outlet amount control method. The method comprises the steps that after the original volume and the original weight of liquid medicine in an infusion bottle are obtained, the cross sectional area of a medical infusion tube and the cross sectional area of a needle are obtained respectively, once that the liquid medicine flows in the medical infusion tube is detected, the initial flowing speed of the liquid medicine in the medical infusion tube is obtained, the real-time weight of the liquid medicine in the infusion bottle, an environmental characteristic parameter set of the environment where a patient is located and a personal physiological characteristic parameter set of the patient are detected in real time, the liquid outlet speed, suitable for the current state of the patient, of the medical infusion tube is obtained finally based on the obtained data, the obtained liquid outlet speed of the medical infusion tube serves as the liquid outlet speed for controlling the liquid medicine in the medical infusion tube in real time, and therefore the liquid outlet amount of the medical infusion tube is adjusted in a personalized mode based on the actual condition of the patient.

Description

technical field [0001] The invention relates to the field of medical infusion control, in particular to a method for controlling the output volume of a non-contact medical infusion tube. Background technique [0002] At present, when medical institutions infuse patients with fluids, medical staff usually adjust the fluid output speed in the medical infusion tube according to the patient's condition, monitor the patient's infusion status, and control the fluid output volume (including the fluid output speed) of the medical infusion tube and the infusion rate. The remaining infusion volume in the bottle, etc.; once the infusion speed of the medical infusion tube is too fast or too slow, the medical staff need to adjust and control the corresponding infusion volume according to the actual situation; of course, the infusion in the medicine bottle is about to reach the usual When the remaining liquid level threshold is reached, the medical staff will promptly connect the liquid i...

Problems solved by technology

[0003] However, there are some problems in the current traditional method of controlling the output of medical infusion tubes: since medical staff usually need to monitor multiple patients, and are not limited to detecting the infusion status of patients, once the medical staff is insufficient or the medical staff is busy, It is difficult to control the output of the medical infusion tube in a timely manner, resulting in the discomfort of the infusion to the patient due to the failure of timely and appropriate control of the output of the medical infusion tube, and even affecting the patient's health due to air input or blood return.

Not only that, medical staff usually touch the medical infusion tube with their hands to control the output of the medical infusion tube, which will inevitably have an adverse effect on the hygiene of the medical infusion tube; since the control of the output of the medical infusion tube is mainly based on medical care Due to the experience of the staff, it is difficult for the medical staff to make targeted individual adjustments according to the actual situation of each patient, and it is impossible to adjust the output volume of the medical output tube to the best output volume in line with the actual situation of the patient.
