The flexible finger sleeve can deform according to the shape and size of the finger to adapt to the size of the finger, avoiding the compression of the finger caused by the spring structure in the prior art, making the detection process more comfortable. Meanwhile, the finger sleeve is a closed structure with an opening, so that the finger can be completely wrapped when inserted into the finger sleeve. The accommodation chamber 5 formed inside the finger sleeve body 1 has a structure with a large diameter at the inlet end and a small diameter at the other end. The front end is clamped more tightly, and the rear end is retracted to better fit the shape of the finger while inserting the finger. It can also prevent external light from penetrating into the inside of the finger sleeve, effectively avoiding the influence of external light on the test results, and greatly improving the test accuracy.

[0025] Specifically, the finger sleeve body 1 is a one-piece structure or a split structure. That is, the finger sleeve body 1 can be a one-piece structure or a split structure. The one-piece structure of the finger sleeve body 1 is formed by one-piece injection molding to form the shape of a finger sleeve. In this embodiment, the finger sleeve body 1 is a split structure. The split finger sleeve body 1 includes an upper finger sleeve 11, a lower finger sleeve 13, and a finger sleeve pressing assembly 15.

[0026] Furthermore, a mounting portion 17 is respectively extended outward on opposite sides of the upper finger sleeve 11 and the lower finger sleeve 13, and the finger sleeve pressing assembly 15 includes an upper fixing member 151, a lower fixing member 153 and a fastener. The upper fixing member 151 and the lower fixing member 153 are fixedly installed on the mounting portion 17, and the fastener passes through the upper fixing member 151, the mounting portion 17 and the lower fixing member 153 to clamp the upper fixing member 151 and the lower fixing member 153 on the mounting portion 17 to assemble the upper finger sleeve 11 and the lower finger sleeve 13 into one.

[0027] Specifically, in this embodiment, the fasteners are screws. Of course, in other embodiments, pins or rivets may also be used. The screws pass through the upper fixing member 151, the mounting portion, and the lower fixing member 153, clamping the mounting portions of the upper and lower finger sleeves 13 between the upper fixing member 151 and the lower fixing member 153, thereby pressing the upper and lower finger sleeves 13 together.

[0028] Preferably, the inner wall of the finger cuff body 1 protrudes toward its centerline to form a plurality of spaced-apart, strip-shaped finger-fitting portions 18, to better fit the finger and effectively block other light sources from entering from the rear end. Specifically, in this embodiment, the finger-fitting portions 18 are three spaced-apart, strip-shaped protrusions. Of course, in other embodiments, the finger-fitting portions 18 may also be three, four, or more, and the number can be increased or decreased depending on the length of the finger cuff.

[0029] Specifically, in this embodiment, the finger cuff body 1 is made of silicone. Silicone has a certain degree of deformability. Under the influence of elastic deformation, the finger cuff body 1 can fully adapt to the shape and size of the finger and can perfectly fit the finger, thereby effectively improving the test accuracy.

One end of each of the two FPCs 33 is connected to the PCB board 31, the LED 35 is mounted on the other end of one of the FPCs 33, and both are embedded in the periphery of the finger sleeve body 1 at the same time. The PD 37 is mounted on the other end of the other FPC 33, and both are embedded in the periphery of the finger sleeve body 1 at the same time. It should be noted that in this embodiment, as Figure 1As shown, the LED 35 is on the top and the PD 37 is on the bottom, of course, in other embodiments, the LED 35 can also be on the bottom and the PD 37 is on the top, so the positions of the two devices LED 35 and PD 37 can be interchangeable. Among them, the PCB 31 is a control circuit board, the FPC 33 is a flexible circuit board, the LED 35 is a light-emitting diode, the PD 37 is a sensor, the silicone finger sleeve and the blood oxygen FPC 33 form a blood oxygen test part, the sensor PD 37 and the light-emitting diode LED 35 on the finger sleeve can quickly detect the blood oxygen saturation, by measuring the light intensity difference between the emitted and transmitted light, the blood oxygen saturation in the blood is calculated, and the result is displayed on the screen. The detection assembly 3 and the finger sleeve body 1 combine to form a blood oxygen test part for detecting the blood oxygen value of the human body. Its main detection principle is to use infrared light and infrared light absorption principle. Hemoglobin is the main oxygen carrier in blood, and saturation refers to the proportion of oxygen combined on hemoglobin. The oximeter emits infrared light and infrared light into the blood, and then measures the light intensity change during transmission. When infrared light passes through blood, it encounters a decrease in light intensity due to the absorption of hemoglobin. However, when oxygen is combined on hemoglobin, it reduces its ability to absorb infrared light, thus causing an increase in transmitted light intensity. By measuring the light intensity difference between the emitted and transmitted light, the blood oxygen saturation in the blood is calculated. Blood oxygen detection usually displays the result as a percentage, indicating the oxygen content in the blood. During use, the finger is inserted into the top of the silicone finger sleeve, the sensor PD 37 and the LED 35 on the finger sleeve can quickly detect the blood oxygen saturation, and the FPC 33 connecting line transmits the signal to the main control circuit board for analysis, and the final result is displayed on the display screen.

[0033] It can be understood that the finger sleeve body 1 is contained in the shell 20, that is, the entire finger sleeve is installed inside the shell, further improving the anti-interference performance. Compared with the traditional technology, the internal structure is simple, the overall machine is small, and the carrying is convenient.

[0034] The blood oxygen detection finger sleeve and detector provided by the embodiment of the utility model can be deformed according to the shape and size of fingers through the flexible finger sleeve, so as to adapt to the size of fingers, avoid the compression feeling of fingers caused by the spring structure in the prior art, make the detection process more comfortable, meanwhile, the finger sleeve is a closed structure with an opening and a cylindrical shape, so that the finger can be completely wrapped when the finger is inserted into the finger sleeve, the accommodation chamber 5 formed in the inside of the finger sleeve main body 1 is arranged as a structure with a large port diameter at one end and a small port diameter at the other end, the front end is clamped more tightly, the rear end is retracted, so as to be more fitted to the shape of the finger while the finger is inserted, and external light can be prevented from penetrating into the inside of the finger sleeve, external light is effectively prevented from entering the inside of the finger sleeve and affecting the test result, and the test precision is greatly improved.
