[0002] The main measurement indicators of the oximeter are pulse rate, blood oxygen saturation, and perfusion index. Blood oxygen saturation is one of the important basic data in clinical medicine. Blood oxygen saturation refers to the percentage of the combined O2 capacity in the total blood volume to the total combined O2 capacity. The circuit board is a highly reliable and excellently flexible printed circuit board made of polyimide or polyester film as the substrate. It has the characteristics of high wiring density, light weight, thin thickness, and good bendability. The circuit board is one of the important components of the oximeter, so a combined oximeter circuit board is needed.

[0003] When operators assemble the oximeter, they often use the corresponding combined oximeter circuit board. However, in actual use, the circuit board is mostly fixed or welded, which is inconvenient to install and disassemble the circuit board. In addition, the circuit board has a single fixing method, which may cause it to slip during long-term use, affecting the normal use of the oximeter and reducing its practicality.

[0012] In the daily use of the combined oximeter circuit board, the operator places the circuit board between the bottom plate, the inside of the mounting plate and the fixed plate, and then continues to slide the circuit board. At this time, the outer surface of the circuit board will continuously press the outer surface of the fixed plate, and then the fixed plate will drive the moving rod to slide. At the same time, the moving rod will push the slider to slide inside the strip groove and on the surface of the round rod. Then the slider will squeeze the spring and put it in a compressed state, so that the circuit board can be installed, otherwise it can be disassembled.
