Problems solved by technology

Therefore, high-pressure injectors usually require simple, convenient, efficient and safe operation. However, the high-pressure injector head usually needs to be installed with a fixed motor to push the syringe. The entire high-pressure injector head is too close to the MRI environment, so the motor will generate a strong magnetic field after power-on. As a result, there is mutual electromag

Abstract

The invention discloses a high-pressure syringe driving device with flexible shaft connection. The high-pressure syringe driving device comprises a shielding case, a motor, a flexible shaft, a flexible shaft fixing screw sleeve, a bent tube assembly, a driving gear, a transmission gear and a pair of lead screws, wherein the shielding case is made of a metallic material through enclosing, the motor is arranged in the shielding case and is shielded, one end of the flexible shaft is correspondingly connected with an output shaft of the direct-current motor, the flexible shaft fixing screw sleeve is used for correspondingly fixing the flexible shaft to the output shaft of the motor, the bent tube assembly sleeves the outer side of the flexible shaft and at least comprises one bend, the driving gear is in fit with the other end of the flexible shaft, the transmission gear is engaged with the driving gear, and the lead screws are in fit with the center of the transmission gear. According to the high-pressure syringe driving device, the motor can be used in an MRI nuclear magnetic environment and can meet the requirements of a thrusting rod on relatively high thrust during needle cylinder thrusting, the power and torque are relatively high, and the reliability is high.

Description

technical field [0001] The invention relates to a high-pressure injector transmission device with flexible shaft connection. Background technique [0002] A high-pressure injector is one of the devices often used in medical equipment, which is used to inject liquids such as contrast agents and saline into the human body, and to enhance the effects of medical imaging such as X-ray or electromagnetic imaging. Therefore, high-pressure injectors usually require simple, convenient, efficient and safe operation. However, the high-pressure injector head usually needs to be installed with a fixed motor to push the syringe. The entire high-pressure injector head is too close to the MRI environment, so the motor will generate a strong magnetic field after power-on. As a result, there is mutual electromagnetic interference with the surrounding equipment, so that the equipment in the entire MRI environment cannot be normal. For this reason most of the products currently on the market u...
