Water level and catheter flow velocity monitoring system of medical water bag for infusion

Abstract

The invention discloses a water level and catheter flow rate monitoring system of a medical water bag for transfusion, which comprises a light emitting module, a light receiving module, a data processing module, a liquid drop counting module and a flow rate calculation module, which are used for calculating the flow rate V of liquid in a catheter; a display module and a prompt module, which are connected with the data processing module, and the prompt module is connected with the alarm. The water level and catheter flow rate monitoring system of the medical water bag for infusion is provided with the liquid drop counting module, the number of liquid drops is accurately measured through the wave transmitting module and the wave frequency detector, the liquid drops are monitored in real time, and then the real-time flow rate can be accurately measured through a calculation formula in the flow rate calculation module; According to the invention, the light emitting module and the light receiving module are arranged on the two sides of the medical water bag, the position of liquid in the water bag is judged according to the energy difference of light penetrating through the medical water bag, and therefore the height of the medical water bag can be accurately judged in real time and accurately.

Description

technical field [0001] The invention belongs to the field of medical technology, and in particular relates to a water level and catheter flow rate monitoring system of a medical water bag for infusion. Background technique [0002] The vast majority of existing infusion treatments are performed through infusion tubes, which require manual monitoring by nurses or family members during the infusion, which consumes a lot of manpower, and is prone to dripping empty during the infusion under manual supervision, or the needle is blocked during the infusion process , may cause certain danger to the patient. On the other hand, some devices that detect the drip rate usually estimate the rate by checking the drip rate of the liquid in the Murphys tube, actively control the drip rate through a peristaltic pump, and even calculate the weight by weighing However, the method for detecting the liquid velocity in the infusion tube has the disadvantages of bulky equipment, high power consump...

AI Technical Summary

Problems solved by technology

[0004] Although the liquid flow rate detection system for the infusion tube can detect the flow rate in the catheter, it can only judge whether there is liquid flow in the catheter, but cannot accurately detect the flow rate, which is inconvenient to use, and the water level of the water bag cannot be checked. detection
