CT room high-pressure injector auxiliary device convenient for realizing pressure alarm

Abstract

The invention discloses a CT room high-pressure injector auxiliary device capable of achieving pressure alarm conveniently. The CT room high-pressure injector auxiliary device can automatically give an alarm and cut off injection when the pressure exceeds a patient bearing value and can be suitable for high-pressure injectors of different models. The CT room high-pressure injector auxiliary device facilitating pressure alarm comprises a main machine and an arm pressure feedback device. A pressure display is arranged on the host; universal wheels are arranged at the bottom of the main machine; a supporting rod is arranged at the top of the main machine; a mounting bracket is arranged at the upper end of the supporting rod; a high-pressure injector is arranged on the mounting bracket; the high-pressure injector is provided with a needle cylinder; a pressure head is arranged on the needle cylinder; the arm pressure feedback device is arranged on the supporting rod; by adopting the CT room high-pressure injector auxiliary device convenient for realizing the pressure alarm, the use safety of the high-pressure injector can be improved, and the application range is wide.

Description

technical field [0001] The invention relates to the safe use of a CT high-pressure injector, in particular to an auxiliary device for a high-pressure injector in a CT room which is convenient for realizing pressure alarm. Background technique [0002] It is well known that with the development of X-ray, rapid film changer, image intensifier and artificial contrast agent, it is gradually applied in clinical practice. The high-pressure injector has become an auxiliary device in the radiology diagnosis and treatment system. The basic function of the high-pressure syringe is to inject a sufficient amount of high-concentration X-ray contrast agent into the examination site quickly and accurately through percutaneous puncture into the blood vessel or through the original orifice of the human body within a certain period of time, which can diagnose the lesion. Angiography and treatment. [0003] The existing high-pressure injector realizes the pressure alarm generally through ext...

AI Technical Summary

Problems solved by technology

[0003] Existing high-pressure injectors usually achieve pressure alarm through external detection, and then control the high-pressure injector to stop injection. It is impossible to realize automatic alarm and automatic cut-off of injection when the pressure exceeds the value; in order to ensure the safety of injection, it is necessary to design a high-pressure injector. Alarm and automatic cut-off device, thus improving the safety of high-pressure injector use
