[0002] In the modern medical system, intravenous infusion is one of the most common and important drug administration methods in clinical treatment. Whether it is to supplement the water, electrolytes, and nutrients required by the human body, or to input various drugs to treat diseases, intravenous infusion plays a key role. However, the precise control of the infusion speed during the infusion process is crucial for the treatment effect and patient safety, which has also promoted the emergence of the automatic monitoring and speed regulation device for infusion. With the continuous progress of medical technology, simple electronic infusion devices have gradually been applied clinically. The existing electronic infusion devices mainly consist of a power drive system, a monitoring system, a control system, a display system, and an alarm system.

[0014] Compared with the prior art, the present invention has the following beneficial effects: Through the settings of the infusion regulation mechanism and the infusion monitoring mechanism, after placing the infusion tube inside the infusion driving housing, the hospital bed railing is snapped into the inside of the installation connecting piece, and the installation locking bolt is tightened. At this time, the fixation of the entire device is achieved. By rotating the infusion regulation bolt, the rotation of the infusion regulation bolt drives the limit moving part to move back and forth. Under the limitation of the limit fixing part during the back-and-forth movement of the limit moving part, at this time, through the clamping of the limit fixing part and the limit moving part, the fixation of infusion tubes with different diameters is achieved, improving the applicable range of the entire device.

[0015] Through the settings of the infusion regulation mechanism and the infusion monitoring mechanism, by rotating the regulation locking bolt, the rotation of the regulation locking bolt drives the regulation connecting part to move up and down. The up-and-down movement of the regulation connecting part drives the regulation connecting rod to move up and down. The up-and-down movement of the regulation connecting rod drives the infusion connection slider to slide. The sliding of the infusion connection slider drives the infusion extrusion part to slide. The sliding of the infusion extrusion part achieves the extrusion of infusion tubes with different diameters, improving the applicable range of the entire device. By turning on the infusion heating part, the infusion heating part realizes the heating of the infusion tube, reducing the stimulation of cold medicine liquid to the patient and improving the comfort of the patient during infusion. By turning on the infusion driving motor, the rotation of the shaft of the infusion driving motor drives the infusion driving part to rotate. The rotation of the infusion driving part drives the infusion extrusion part to rotate. The rotation of the infusion extrusion part achieves the extrusion of the infusion tube, and then realizes the delivery of the medicine liquid, enabling the medicine liquid delivery volume to be accurately controlled and improving the treatment effect on the patient.

[0016] Through the settings of the infusion regulation mechanism and the infusion monitoring mechanism, during normal infusion, the liquid medicine in the pipeline is transparent with a high light transmittance, and the output signal of the photosensitive receiving tube of the optical sensor is stable; when blood return occurs, the blood enters the detection area of the optical sensor, and the light transmittance decreases significantly. The light transmittance of the blood is about 60% lower than that of the liquid medicine. The signal received by the photosensitive receiving tube of the optical sensor drops suddenly, triggering the warning horn to turn on, and the warning horn emits an alarm, realizing the monitoring of blood return during infusion and improving the usage effect of the entire device.

[0017] Through the settings of the infusion regulation mechanism and the infusion monitoring mechanism, the ultrasonic sensor controls the rotation speed of the infusion driving motor by detecting the pressure of the infusion tube, enabling the stable delivery of the medicine liquid. At the same time, by adjusting the rotation speed of the infusion driving motor, the control of the infusion speed is achieved, making the entire device applicable to patients with different diseases and improving the applicable range of the entire device.

[0018] Through the settings of the infusion adjustment mechanism and the infusion monitoring mechanism, when there are no air bubbles, the intensity of the reflected signal received by the ultrasonic sensor is relatively stable. Once an air bubble passes through the detection area of the ultrasonic sensor, characteristics such as the intensity, phase, and frequency of the reflected signal will change. The ultrasonic sensor converts the received reflected signal into an electrical signal and then transmits it to the signal processing circuit to connect the circuit of the cut-off driving part. The connection of the circuit of the cut-off driving part generates magnetism, and the cut-off driving part attracts the cut-off magnetic block to move forward. The forward movement of the cut-off magnetic block drives the monitoring cut-off slider to move forward. The forward movement of the monitoring cut-off slider, under the action of the cut-off guide wheel and the cut-off transmission rope, realizes the opposite movement of the two groups of monitoring cut-off parts. The opposite movement of the monitoring cut-off parts realizes the cut-off of the infusion tube, avoids air bubbles entering the patient's body, realizes the protection of the patient, and improves the safety of medical treatment.
