Pressure sensor telescopic quick mount

Abstract

The invention relates to a telescopic fast fixing frame for a pressure sensor, belonging to the technical field of medical devices. A telescopic fast fixing frame for a pressure sensor comprises an outrigger adjustment structure, a telescopic adjustment structure and an angle adjustment structure; the outrigger adjustment structure includes The base, the bearing, the worm, the outrigger adjusting rod, the worm wheel and the outrigger; the telescopic adjustment structure includes a fixed outer telescopic sleeve, an inner telescopic rod, a guide keyway structure, an upper end surface gear and a height adjustment structure. The angle adjustment structure includes a lower end surface gear, a baffle plate, a compression spring and a sensor fixing panel. By setting the worm gear and worm structure to drive the change of the angle between the two outriggers, it is stable and reliable during use. By setting the guide keyway structure, the expansion and contraction are guided and will not rotate during the expansion and contraction process; by setting two meshing end gears The adjustment of the angle of the fixed panel of the sensor is realized, and the rotating structure is simpler and more reliable.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a telescopic fast fixing frame for a pressure sensor. 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, and through the pressure sensor and monitor, the liquid pressure in the catheter is converted into numbers and waveforms, and displayed on the screen, which can accurately measure the blood pressure value 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 t...

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
