Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to a sensor fixing device. Background Art
[0002] Arterial blood pressure monitoring is mainly divided into non-invasive and invasive. Invasive arterial pressure monitoring refers to a method of directly measuring arterial blood pressure by placing an arterial catheter into the artery. It is not affected by artificial pressurization, cuff width and tightness, is accurate and reliable, and can be taken at any time. Invasive arterial blood pressure monitoring mainly consists of anticoagulant saline, drip tube, valve, pressure sensor, monitor, pressure sensor interface cable, pressure tube and other components.
[0003] Existing pressure sensors used for invasive arterial blood pressure monitoring are generally placed at the edge of the bed or tied to the patient's arm. Medical staff can easily bump into the pressure sensor at the edge of the bed when passing or working, causing displacement. If tied to the arm, it can also easily cause displacement when the patient moves, thereby affecting the monitoring accuracy of the sensor, or causing the pipes and cables to be pulled loose or fall off.

[0013] Furthermore, the limit pin is slidably connected to the first clamping plate, and the limit pin is detachably connected to the second clamping plate.
[0014] By adopting the above technical solution, the staff moves the limit pin downward so that the limit pin passes through the second splint, thereby limiting the first splint and the second splint to prevent the second splint from opening.
[0015] Furthermore, the placement rack is slidably connected to the bracket, and the abutment rack abuts against the bracket.
