Problems solved by technology
Generally, high-pressure injectors require simple, convenient, efficient and safe operation. However, the existing syringe state detection device for high-pressure injectors passes a sensor detection signal when the syringe rotates in place and disengages. When the signal cannot be detected, it will cause a blind spot in the syringe state detection device, which will affect the use and low reliability

Embodiment Construction
[0020] The technical solutions of the present invention will be clearly and completely described below through specific embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0021] Such as Figure 1-5 As shown, the present invention provides a specific embodiment of a detection device for fixing the high-pressure syringe syringe in place, which is used to detect whether the syringe knob 40 that drives the syringe to rotate is rotated in place and includes a rotation-cooperating with the syringe knob 40 The flange body 10 , the micro switch 20 disposed on the flange body 10 , and the friction member 30 disposed above the micro switch 20 and at least partly in contact with the flange body 10 . The...

The invention discloses a detection device for in-place fixation of a syringe of a high-pressure injector. The detection device comprises a flange body in rotating fit with the syringe, a micro switch arranged on the flange body and a friction piece arranged above the micro switch and at least partially contacting with the flange body, wherein a flange pressed against and contacting with the friction piece and an elastic plunger part arranged on the flange, extending along the axial direction of the syringe and capable of triggering the micro switch to act are arranged at the tail end of the syringe. According to the detection device, physical switch detection is adopted instead of signal detection, and the detection device is higher in stability and detection reliability and low in failure rate.
Description
technical field [0001] The invention relates to a detection device for fixing a needle barrel of a high-pressure injector in place. Background technique [0002] A high-pressure injector is one of the devices often used in medical equipment. It is used to inject liquids such as contrast agents and saline into the human body to enhance the effect of medical imaging such as X-ray or electromagnetic imaging. Generally, high-pressure injectors require simple, convenient, efficient and safe operation. However, the existing syringe state detection device for high-pressure injectors passes a sensor detection signal when the syringe rotates in place and disengages. When the signal cannot be detected, the syringe state detection device will have a blind area, which affects the use and has low reliability. Contents of the invention [0003] In view of this, the object of the present invention is to provide a detection device for fixing the syringe of a high-pressure injector in pla...
