Telescopic quick mounting bracket for pressure sensor

Abstract

The invention relates to a telescopic quick mounting bracket for a pressure sensor, and belongs to the technical field of medical apparatus and instruments. The telescopic quick mounting bracket for the pressure sensor comprises a leg adjustment structure, a telescopic adjustment structure and an angle adjustment structure. The leg adjustment structure comprises a base, a bearing, a worm, leg adjustment rods, a worm wheel and legs. The telescopic adjustment structure comprises an outer telescopic sleeve, an inner telescopic rod, a guide key groove structure, an upper end face gear and a heightadjustment structure. The angle adjustment structure comprises a lower end face gear, a baffle, a pressure spring and a sensor fixing panel. According to the telescopic quick mounting bracket for thepressure sensor, because the worm and worm wheel structure is arranged to drive the two legs to change the included angle between, the mounting bracket is stable in use; because the guide key groovestructure is arranged, extension and contraction are oriented, and no turning happens in the process of extension or contraction; and because the two end face gears which are engaged with each other are arranged, adjustment on the angle of the sensor fixing panel can be implemented, and a turning structure is simpler and more reliable.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a pressure sensor telescopic fast fixing frame. Background technique [0002] Invasive blood pressure can quickly, directly and sensitively reflect the continuous dynamic changes of blood pressure, and can continuously and accurately measure the blood pressure of the subjects. It is a commonly used method for monitoring blood pressure after cardiac surgery. Invasive blood pressure monitoring is to place the cannula in the arterial blood vessel, convert the fluid pressure in the catheter into numbers and waveforms through pressure sensors and monitors, and display them on the screen, which can accurately measure the blood pressure values ​​at each moment in the cardiac cycle . In order to ensure the accuracy of the patient's blood pressure, the pressure sensor must be effectively fixed and kept at the same level as the patient's heart, and the invasive pipeline should be ...

AI Technical Summary

Problems solved by technology

The outriggers of the existing pressure sensor adopt a damping mechanism, which is easy to merge the outriggers due to human factors, resulting in the instability of the fixed bracket, causing the fixed bracket to be skewed and hit the patient; in addition, when the fixed bracket is stretched, because there is no guiding mechanism It is easy to shake and rotate during the telescopic process, and it is not easy to adjust the angle; in addition, the sensor holder panel is complicated to operate when rotating and fixing the angle, and it is not easy to fix and easy to shake
