Infusion monitoring apparatus and monitoring method thereof

Abstract

The invention discloses an infusion monitoring apparatus and a monitoring method thereof. The infusion monitoring apparatus consists of a gravity sensor, a data acquisition unit, a data processing unit, terminal equipment and a power source. The infusion monitoring method comprises the following steps of: leading the sum of the weight of an infusion container, the weight of liquid medicine in the container and the weight of accessories to be equal to the initial weight Wo of the liquid medicine, and automatically judging the weight WG of the liquid medicine in the container by analysis software according to the standard of the infusion container; computing the dynamic change numerical value of the infusion speed, the time required for infusing residual liquid and the liquid level liquid quantity in the infusion container by a microprocessor, and when the dynamic change numerical value of the infusion speed and the liquid level liquid quantity in the infusion container exceed the critical alarm points of the dynamic change numerical value of the corresponding infusion speed and liquid level liquid quantity in the infusion container, sending out an alarm signal; and displaying all data of infusion parameters by a displayer, and sending to a nurse center by a wire network or a wireless network, so that the dynamic change process of the infusion process can be timely monitored by medical workers, and the problem of various inconveniences of the medical workers and the patients during infusion can be solved.

Description

Technical field: [0001] The present invention relates to an infusion monitor and a monitoring method thereof, in particular to a method for digitally converting the infusion flow and voltage values ​​by using a gravity sensor, and using a data acquisition unit and a processing unit to perform calculation and analysis on the collected voltage signal to determine the infusion speed, and then An infusion monitor and a monitoring method thereof for calculating various parameters such as infusion time according to the speed. Background technique: [0002] Now there are a large number of patients in the hospital undergoing infusion every day. The traditional infusion process often lasts for several hours. During this process, someone needs to pay attention to the changes in the liquid in the infusion bottle, because once the infusion is completed, the drug solution is not replaced or the infusion needle is taken out in time.

Problems solved by technology

[0002] Now there are a large number of patients in the hospital undergoing infusion every day. The traditional infusion process often lasts for several hours. During this process, someone needs to pay attention to the changes in the liquid in the infusion bottle, because once the infusion is completed, the drug solution is not replaced or the infusion needle is taken out in time. Blood return phenomenon will occur, medical accidents will occur, and it will threaten the life of the patient in severe cases. During the infusion process, the person, his family members and medical staff generally adopt the method of manual monitoring to observe the infusion volume, liquid speed, infusion time and remaining time. liquid medicine, etc., which brings a great mental burden to the patients themselves, their families and medical staff

Most of the existing infusion devices only have an infusion alarm function, that is, an alarm signal is sent out at the end of the infusion. During the infusion process, patients may worry that the infusion speed is too fast or too slow, failure or interruption occurs, and the infusion alarm device cannot solve

In order to solve the above problems, a device that adopts a photoelectric sensor to measure the infusion speed has been invented in practice. Although this device can measure the infusion speed, there are the following disadvantages in the use process: (1) to adopt a photoelectric sensor, it must be placed on the infusion stand or the infusion tube. Install a special device on the top to fix the photoelectric tube. If the patient interrupts (such as going to the toilet, etc.) infusion and takes off the infusion container, the photoelectric sensor will not work, which is extremely inconvenient to use; (2) the photoelectric tube in the photoelectric sensor cannot automatically distinguish the infusion container. Specification parameters, if you need to set the alarm prompt, you need to set and adjust manually by the nurse, which will increase the workload of the nurse; (3) The photoelectric sensor needs AC power supply, and the photoelectric tube consumes a lot of power, but in the actual use process, the hospital Many occasions cannot be used without AC power (such as infusion halls, etc.)

Therefore, the photoelectric alarm speed measuring device is not practical and cannot be widely used in hospitals.
