Embodiment 1

[0026] Basic as attached figure 1 Shown: Push injection pump for nerve block anesthesia, including:

[0027] The body of the infusion pump, the body of the infusion pump includes a microcomputer system, a pump device, a detection device, an alarm device and a display device. The pump device is used to provide power for infusion and withdrawal. Liquid velocity and flow rate, blockage pressure, leakage and air bubbles are detected and the above signals are fed back to the microcomputer system. The alarm device is used to issue an alarm according to the instructions of the microcomputer system. The display device is used to display the working status of the infusion pump body.

[0028] The body of the infusion pump can use the existing BYZ-810D syringe pump, which has been equipped with a microcomputer system, pump device, detection device, alarm device and display device. The input device in the pump is removed, and the alarm condition of the alarm device needs to be modified. ...

Embodiment 2

[0035]Compared with Embodiment 1, the only difference is that it also includes a solenoid valve. The solenoid valve is used to prevent the liquid in the hose from flowing backward when the motor stops working. The solenoid valve is arranged on the hose, and the solenoid valve is connected to the microcomputer system. The solenoid valve is open when the motor is working, and the solenoid valve is closed when the motor is not working.

Embodiment 3

[0037] The pump device is a finger-shaped peristaltic pump, including a stepping motor and a camshaft driven by the motor. The stepping motor is connected with a microcomputer system, and the microcomputer system controls the running direction and speed of the stepping motor.

Abstract

The invention belongs to the field of medical appliances, and discloses a syringe pump for nerve block anesthesia and having a suction function in order to solve the technical problem that the conventional nerve block operations are completed by many workers. The syringe pump includes an infusion pump body; the infusion pump body includes a microcomputer system, a pump device, a detection device,an alarm device, and a display device; the pump device is used for providing power for infusion and pumping-back; the microcomputer system is used for controlling a working state of the pump device; the detection device is used for detecting the flow speed and the flow amount of liquid, the blocking pressure, leakage and bubbles and feeding the signals back to the microcomputer system; the alarm device is used for sending an alarm according to a command of the microcomputer; a dual-pedal type control device includes a pumping-back pedal and an infusion pedal; the pumping-back pedal is connected to a first signal input device for sending a pumping-back signal to the microcomputer system; and the infusion pedal is connected to a second signal input device for sending an infusion signal to the microcomputer system.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a push injection pump for nerve block anesthesia. Background technique [0002] In clinical surgical anesthesia, nerve block anesthesia is often performed on the patient. The principle of nerve block anesthesia is to puncture the patient's skin with the needle core of the puncture needle, and then adjust the position of the needle tip according to the feedback information of the ultrasonic probe, so that when the needle tip is near the nerve root that needs anesthesia, the anesthetic is injected. During the whole process, intermittent withdrawal is also required, and the angle and position of the puncture needle are kept fixed to ensure that the anesthetic drug will not enter the blood vessel by mistake. [0003] At present, when performing this kind of anesthesia operation, usually one person performs puncture through ultrasound positioning, and the other person injects local ane...
