[0032] A monitoring probe 103 is installed on the blood oxygen saturation monitoring body 102, and one side of the monitoring probe 103 penetrates to the bottom of the mounting base 101;

[0033] An elastic tightening belt 104 is provided on the mounting seat 101, and the elastic tightening belt 104 has a soft lining;

[0034] An adjustment mechanism 2 for adjusting the tightness of the elastic tightening band 104 is installed on the mounting seat 101;

[0035] The adjustment mechanism 2 includes a reel 203 disposed on both sides of the mounting seat 101, a strip frame 201 also fixed on both sides of the mounting seat 101, and a bevel gear 204 fixed on one end of the reel 203;

[0036] A connecting shaft 209 is provided on the front end surface of the mounting seat 101, and two ends of the connecting shaft 209 are fixed with a bevel gear 205 meshing with the bevel gear 1 204, a turbine 206 is fixed on the surface of the connecting shaft 209, and a worm 207 is meshingly connected on the surface of the turbine 206, and two ends of the elastic tightening belt 104 pass through the two groups of strip frames 201 respectively, and are fixedly connected to the surfaces of the two groups of winding shafts 203;

[0037] A mounting groove is provided on one side of the front end face of the mounting seat 101 close to the worm 207, the worm 207 is located in the mounting groove, and both ends of the worm 207 are rotatably connected to the mounting seat 101 through bearings, a symmetrically arranged support plate 1 is fixed to the front end face of the mounting seat 101, a connecting shaft 209 is rotatably connected to the support plate 1 through a bearing, symmetrically arranged support plates 2 are fixed to both sides of the mounting seat 101, and the winding shaft 203 is rotatably connected to the support plate 2 through a bearing;

[0038] An adjusting disk 208 is fixed on the surface of the worm 207, and anti-slip teeth are provided on the surface of the adjusting disk 208;

[0039] The interior of the strip frame 201 is rotatably connected to symmetrically arranged rollers 202 via bearings, and the elastic tightening belt 104 is located between two groups of rollers 202 to reduce the contact friction between the elastic tightening belt 104 and the strip frame 201 .

[0040] In this embodiment: the monitoring device for internal circulation blood oxygen saturation, when in use, when it is necessary to monitor the oxygen content in arterial blood;

[0041] The elastic tightening band 104 is put on the finger, and the elastic tightening band 104 has a certain elasticity. When the elastic tightening band 104 is tightened, the monitoring probe 103 under the mounting seat 101 can be attached to the skin. The monitoring probe 103, in cooperation with the blood oxygen saturation monitoring body 102, emits light through the monitoring probe 103 and monitors the blood oxygen saturation by measuring the intensity change of the light passing through the finger;

[0042] When adjusting the elastic tightening band 104 to a proper tightness according to different people, the adjusting disk 208 is first rotated, and the surface of the adjusting disk 208 is provided with anti-slip teeth, so as to increase the friction between the hand and the adjusting disk 208 and improve the rotation effect of the adjusting disk 208;

[0043] When the adjusting disk 208 rotates, the worm 207 is driven to rotate, and the worm 207 drives the turbine 206 to rotate, and the turbine 206 drives the connecting shaft 209 to rotate. The setting of the worm 207 and the turbine 206 can play a role in limiting the rotation of the connecting shaft 209.

[0044] When the connecting shaft 209 rotates, the two sets of bevel gears 205 are driven to rotate. Since the bevel gear 205 is meshed and connected with the bevel gear 1 204, the bevel gear 1 204 is driven to rotate. The winding shaft 203 is driven to rotate on the supporting plate 2 by the bevel gear 1 204. With the rotation of the two sets of winding shafts 203, the two ends of the elastic tightening belt 104 are wound or released, so that the elastic tightening belt 104 can adjust the tightness to adapt to fingers of different thicknesses, ensuring that the monitoring device is suitable for users of different ages and body shapes. The adjustable elastic tightening belt 104 can reduce the pressure on the skin, provide a more comfortable user experience, and improve the use effect of the device.

[0045] When monitoring a baby, the elastic tightening belt 104 is more flexible. By adjusting the tightness of the elastic tightening belt 104, the elastic tightening belt 104 can be put on the wrist for real-time monitoring, thereby improving the flexibility of the device.

[0046] When the elastic tightening belt 104 is rolled up, two sets of rollers 202 are arranged on the strip frame 201, and the two sets of rollers 202 are located on both sides of the elastic tightening belt 104, so that the friction between the elastic tightening belt 104 and the strip frame 201 can be reduced by the arrangement of the rollers 202, and the smoothness of the elastic tightening belt 104 can be improved;

[0047] The elastic tightening band 104 has a soft lining, which can reduce direct pressure on the skin, thereby reducing discomfort when worn for a long time, and can reduce friction between the skin and avoid skin wear or abrasion caused by long-term contact.

[0048] Going further;

[0049] In an optional embodiment, a protective shell 210 is fixed to the surface of the mounting base 101 , a rectangular opening is opened on the surface of the protective shell 210 , and a portion of the adjustment disk 208 extends out of the rectangular opening opened in the protective shell 210 .

[0050] In this embodiment, the protection shell 210 is provided to protect the bevel gear 1 204, the bevel gear 205, the turbine 206 and the worm 207, so as to avoid damage to the skin during the rotation process.

[0051] Going further;

[0052] In an optional embodiment, a second contact disk 213 is fixed to the surface of the worm 207, a first contact disk 212 is arranged below the second contact disk 213, the first contact disk 212 is sleeved on the worm 207 through the opened through hole, a spring 211 is fixed between the worm 207 and the mounting seat 101, the spring 211 is sleeved on the worm 207, the spring 211 is in a compressed state, a telescopic rod is fixed between the first contact disk 212 and the mounting seat 101, and the telescopic rod is used to limit the rotation of the first contact disk 212.

[0053] In this embodiment: while the worm 207 is rotating, since the spring 211 is in a compressed state, the rebound force of the spring 211 drives the contact plate 1 212 and the contact plate 2 213 to fit tightly together. Therefore, due to the friction force of the contact, after the worm 207 rotates a certain number of circles, the stability of the worm 207 can be improved, and unintentional rotation is not likely to occur.

[0054] Going further;

[0055] In an optional embodiment, a buffer cotton 105 is fixed to the lower surface of the mounting base 101 , and the buffer cotton 105 is provided with a docking hole adapted to the monitoring probe 103 , and the extended portion of the monitoring probe 103 is located in the docking hole provided in the buffer cotton 105 .

[0056] In this embodiment, by providing the cushioning cotton 105, when the mounting seat 101 contacts the skin, the cushioning cotton 105 is provided in the middle, thereby reducing the pressure of contact with the skin and improving the comfort of monitoring.

[0057] It should be noted that: the elastic tightening band 104 can be released to a fluffy state through the adjustment mechanism 2, and the elastic tightening band 104 can be pulled to one side so that the elastic tightening band 104 does not block the monitoring probe 103. At this time, the mounting base 101 can be attached to the abdominal position so that the monitoring probe 103 is in contact with the abdominal skin, and the measurement operation of the abdominal position can also be realized, thereby improving the practicability and flexibility of this device.

[0058] The working principle and use process of the present invention are as follows: when the monitoring device for internal circulation blood oxygen saturation is used, when it is necessary to monitor the oxygen content in arterial blood; the elastic tightening band 104 is put on the finger, and the elastic tightening band 104 has a certain elasticity. When the elastic tightening band 104 is tightened, the monitoring probe 103 under the mounting seat 101 can be attached to the skin. With the cooperation of the blood oxygen saturation monitoring body 102, the monitoring probe 103 emits light and monitors the blood oxygen saturation by measuring the intensity change of the light passing through the finger; and when the elastic tightening band 104 is adjusted to an appropriate tightness according to different people, the adjusting disk 208 is first rotated, and while the adjusting disk 208 is rotated, the worm 207 is driven to rotate, and the worm 207 drives the The turbine 206 rotates, and the turbine 206 drives the connecting shaft 209 to rotate; while the connecting shaft 209 rotates, it also drives the two sets of bevel gears 205 to rotate. Since the bevel gear 205 is meshed and connected with the bevel gear 1 204, the bevel gear 1 204 is driven to rotate, and the winding shaft 203 is driven to rotate on the support plate 2 through the bevel gear 1 204. With the rotation of the two sets of winding shafts 203, the two ends of the elastic tightening belt 104 are wound or released, so that the elastic tightening belt 104 can adjust the tightness to adapt to fingers of different thicknesses; when monitoring the baby, the elastic tightening belt 104 is more flexible. By adjusting the tightness of the elastic tightening belt 104, the elastic tightening belt 104 can be put on the wrist for real-time monitoring, thereby improving the flexibility of the device.
