Abstract

The invention discloses a high-pressure injector. The high-pressure injector comprises a push rod and a piston and further comprises a pressure sensor and a signal cable, and the pressure sensor is located between the push rod and the piston and connected to the push rod and the piston. The push rod is provided with a cavity extending in the axial direction, the side wall of the push rod is provided with a wiring channel, the wiring channel is communicated with the cavity, and the signal cable penetrates through the wiring channel, is inserted into the cavity and is electrically connected to the pressure sensor. The cavity and the wiring channel provide the accommodating space for the signal cable to protect the signal cable, so that the signal cable is limited in the push rod, the signalcable is isolated from an area outside the push rod, and the signal cable is prevented from being corroded by a liquid when the piston deforms to generate liquid leakage so that the service life of the signal cable is prolonged.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a high-pressure injector. Background technique [0002] In the high-pressure syringe of medical equipment, the real-time detection of the pressure during the injection process is one of the very important functions. The purpose is to prevent medical accidents caused by subcutaneous penetration. The pressure sensor is used to directly measure the pressure in the syringe, and improve the response speed and measurement accuracy. However, since the pressure sensor is connected to the piston, the signal cable of the pressure sensor will also enter the syringe with the piston and move in the syringe; if the piston leaks, the signal cable will be at risk of being corroded. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a high-pressure in...
