Abstract

An automatic infusion detection and alarm device comprises a strain gauge pressure measurement module, a signal amplification module, an AD module, a microprocessor module, a display module, an alarm module and a communication module. The working steps are as follows: When the "drum needle" situation occurs, the pressure measurement module senses the pressure change, converts it into an analog signal and then transmits it to the signal amplification module. The amplified signal is converted by the AD module and then sent to the microprocessor module. After processing the signal, the processor transmits the data to the main processor module through the communication module, and the display module shows the location of the situation, and the alarm device simultaneously alarms to remind the medical staff to deal with it in time, so as to realize remote monitoring and reflect a more humanized heart-warming service.

Description

An automatic detection and alarm device for transfusion

technical field

The utility model relates to an intelligent infusion alarm device, in particular to an electronic infusion "drum needle" condition alarm device based on strain gauge pressure measurement, which can detect hand infusion status and prompt nurses.

Background technique

Infusion is now the main way to treat diseases, mainly relying on manual care, but they cannot accompany the patient all the time. When the patient falls asleep or accidentally causes the "bulging needle", it is generally too late to deal with it , Swelling will leave a psychological shadow on the patient.

Contents of the invention

In order to reduce unnecessary harm caused by momentary negligence during infusion and ensure the physical and mental health of patients, the utility model provides an automatic infusion detection and alarm device, which can detect the state of hand infusion at all times and achieve the purpose of personal service.

The technical scheme of the utility model: a strain gauge pressure measuring type intelligent infusion alarm device, the intelligent alarm device includes a strain gauge pressure measurement module, a signal amplification module, an AD conversion module, a microprocessor module, a main processor module, and an alarm module , display module and communication module. When the "drum needle" situation occurs, the pressure measurement module senses the pressure change, converts it into an analog signal and then transmits it to the signal amplification module. The amplified signal is converted by the AD module and then sent to the microprocessor module. After the microprocessor processes the signal, the The data is transmitted to the main processor module through the communication module, and the display module shows the location of the situation, and the alarm device simultaneously alarms to remind the medical staff to deal with it in time, so as to realize remote monitoring and reflect a more humanized heart-warming service.

Detailed ways

As shown in Figure 2, the utility model can be divided into: strain gauge pressure sensor (9), signal amplification device (10), AD conversion device (11), single-chip microprocessor (12), 24L01 wireless module (13) , single-chip main processor (14), 1602 display screen (15), buzzer (16).

When the smart alarm is in use, the strain gauge load cell (9) is placed on the hand, and fixed on the outside of the needle inserted into the hand with medical adhesive tape, 1 to 2 millimeters away from the needle. When the "drum needle" situation occurs, the pressure measurement module (1) senses the pressure change, converts it into an analog signal and transmits it to the signal amplification module (2), and the amplified signal is converted by the AD module (3) and then sent to the microprocessor Module (4), the microprocessor processes the signal and transmits the data to the main processor module (6) through the communication module (5), the display module (7) displays the status position, and the alarm device (8) simultaneously alarms to remind the medical staff Deal with it in a timely manner.

When the "drum needle" situation occurs, the skin of the hand swells rapidly, and the thin surface of the hand that is in contact with the sensor (9) is squeezed to generate a current signal. The electrical signal is amplified by the AD602 (10), and then converted into a voltage analog signal by the AD conversion device (11), and the data is initially processed by the 51 single-chip microprocessor (12).

The processed data is transmitted to the main processor (14) of the 51 single-chip microcomputer through the wireless transmission module 24L01 (13), and the single-chip microcomputer (14) compares the data to calculate the relative difference. When the difference is large, the 51 single-chip microcomputer (14) controls the buzzer (16) Alarm, at the same time 1602 liquid crystal (15) displays the bed or patient position where the situation occurs. After the above processing, real-time monitoring of patient infusion and caring service are realized.
