Pressure-adjustable infusion device for neurointervention operation

Abstract

The invention discloses a pressure-adjustable infusion device for a neurointervention operation. The pressure-adjustable infusion device comprises a pressure-adjustable infusion device body, a shell, a display screen, a key area, a handle, a motor control module, a data processing module, a dynamic balance module, an embedded plate, a limiting plate, an infusion tube, a driving motor, a driving shaft, a flat key, a conductor, an insulating sleeve, a supporting plate, a cam, an open hole, an electric push rod, an adjusting plate, a protrusion, an abutting rod, a pressure sensor, a controller, a connector, a push rod, a groove, a spring, a push block, an inclined surface, a threaded rod, a knob, an adjusting block, a cover plate, a limiting block, a friction strip, an opening, a guide plate, a baffle and a bolt. The pressure-adjustable infusion device has the advantages that infusion pressure can be adjusted while infusion is conducted in a peristaltic mode, the pressure-adjustable infusion device is also suitable for use of infusion tubes of different models and infusion of different liquid medicine, pressure adjustment can be achieved without resetting the infusion pressure, the pressure-adjustable infusion device is suitable for being used under the condition that the infusion precision requirement is high, and safe and stable infusion is realized.

Description

technical field [0001] The invention relates to a pressure-adjustable infusion device, in particular to a pressure-adjustable infusion device for nerve interventional surgery, which belongs to the technical field of nerve interventional surgery applications. Background technique [0002] Neurointerventional surgery is a minimally invasive surgical method for the treatment of intracranial vascular diseases developed in recent decades. The difference between it and traditional surgery is that traditional surgery is traumatic and painful, and it requires more functions of the heart, liver, lungs and kidneys. High, need craniotomy. However, minimally invasive surgery is also used to treat cerebrovascular diseases. It does not require craniotomy. The usual way to treat it from outside the blood vessel is to puncture the femoral artery, then enter the pipeline, and finally use a very thin tube to enter the brain. Blood vessels, embolization of aneurysms, expansion or placement of...

Problems solved by technology

[0003] In the patent document "CN104857595A Air Pump Portable Infusion Equipment", it effectively monitors abnormal conditions such as air bubbles, empty pipes, and infusion tube blockages. When an abnormality occurs, an alarm is issued and the infusion channel is automatically cut off. However, it lacks real-time detection of internal infusion pressure. It is difficult to use in the case of high infusion uniformity requirements, and it is impossible to control the infusion pressure in real time, especially for micro-infusion or the need to maintain consistent real-time infusion volume, and it is inconvenient to adjust the pressure, and it is difficult to maintain the pressure after pressure adjustment After the tube is changed, the pressure needs to be readjusted to adapt to the use of different types of infusion tubes, increasing the amount of operation, and it also brings inconvenience to the adjustment when delivering different concentrations of liquid medicine, which is prone to operational errors and accident risks

There is still no pressure-adjustable infusion device for neurointerventional surgery with a reasonable and reliable structure and real-time pressure adjustment
