[0020] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.
[0021] The pulse oximeter probes currently available on the market typically employ a multi-layered stacked structure. However, this stacking structure is often flawed, resulting in misalignment between the light-emitting and receiving sensors and inaccurate measurement data.
[0022] To resolve this issue, please refer to Figure 1-5 A reusable fabric butterfly-shaped strap-on pulse oximeter includes: a pulse oximeter 1 and a strap 19 for use with the pulse oximeter 1. The pulse oximeter 1 includes a first piece of fleece 10 and a second piece of fleece 11. The first piece of fleece 10 has a pair of perforated holes 12, and the second piece of fleece 11 has a pair of perforated holes 13. The first pair of perforated holes 12 and the second pair of perforated holes 13 are positioned opposite each other. A pair of transparent sheets 14 are fixed between the first piece of fleece 10 and the second piece of fleece 11, and the transparent sheets 14 are located inside the perforated holes 13. A transparent sheet 14 is sandwiched between perforated holes 12 and 13 by heat pressing between velvet fabric 10 and velvet fabric 2. An FPC component 15 is provided below velvet fabric 2. A light-shielding layer 16 is provided at the bottom of the FPC component 15. A velvet fabric 3 17 is provided at the bottom of the light-shielding layer 16. Velvet fabric 2 11 and velvet fabric 3 17 are fixed together by heat pressing. A Velcro hook side 18 is fixed at the bottom of velvet fabric 3 17. A groove 110 is opened on the back of the strap 19. Velcro fleece 111 is fixed in the groove 110.
[0023] When in use, the wrapping layer is surrounded by multiple layers of butterfly-shaped fabric, which provides strong wrapping and good comfort. The fabric is also highly breathable. After being installed on the instep, the light-emitting device 154 and the receiving device 155 are aligned after bending. With the addition of the light-blocking layer 16 on the back, the accuracy of the measurement data can be improved. The Velcro hook surface 18 at the bottom of the fleece 3 17 is attached to the Velcro fleece 111 in the groove 110 of the strap 19, so that it can be attached and fixed to the strap 19. The shape of the groove 110 is offset from the blood oxygen probe 1 by a certain distance, so that the two can be positioned and aligned. It is fixed on the foot by the strap 19 for blood oxygen detection.
[0024] In the actual implementation process, the pulse oximeter probe body is subjected to significant bending and wrapping force, which affects the comfort of the product. Figure 2 and Figure 3 As shown, the FPC assembly 15 includes a welding plate 151, a pair of flexible FPC boards 152, and a data transmission line 156. The pair of flexible FPC boards 152 are located on opposite sides of the welding plate 151. The welding plate 151 and the pair of flexible FPC boards 152 are connected by a flexible bending member 153. A light-emitting device 154 is fixedly mounted on one flexible FPC board 152, and a receiving device 155 is fixedly mounted on the other flexible FPC board 152. The cable at the end of the data transmission line 156 is heat-fused to the welding plate 151, and the data transmission line 156 is electrically connected to the light-emitting device 154 and the receiving device 155.
[0025] In use, the flexible FPC board 152 and the flexible bending component 153 make the FPC assembly 15 more flexible, reducing the bending force of the pulse oxygen probe 1 during binding and improving the comfort of using the product. The better flexibility allows the light-emitting device 154 and the receiving device 155 to correspond vertically, improving the accuracy of measurement. The detection data is transmitted through the data transmission line 156, making it convenient to view and analyze the detection data.
[0026] In the specific implementation process, such as Figure 4 and Figure 5 As shown, the front of the strap 19 is fixed with Velcro loop 2 193, the front of the strap 19 is fixed with Velcro loop 3 194, the back of the strap 19 is fixed with Velcro hook 2 191, and the back of the strap 19 is fixed with Velcro hook 3 192.
[0027] When in use, the strap 19 is removed and replaced using Velcro. When in use, pull the third Velcro hook 191 around the instep and attach it to the Velcro loop 194. Then pull the Velcro hook 192 around the ankle and attach it to the Velcro loop 193. This Y-shaped strap 19 structure utilizes the foot structure to securely fix the blood oxygen probe 1. The use of Velcro makes it more convenient for users to use.
[0028] In the specific implementation process, such as Figure 2 As shown, a pair of transparent sheets 14 are punched in a convex shape. The convex surfaces of the transparent sheets 14 pass through the hollow holes 12 and are parallel to the surface of the velvet cloth 10. The velvet cloth 10 is made of light-colored Lycra fabric.
[0029] When in use, the transparent sheet 14 is parallel to the surface of the velvet cloth 10 so that it can fit against the skin. During testing, the transparent sheet 14 fits against the skin, making the test data more accurate. The velvet cloth 10, which comes into contact with the skin, should be made of a more skin-friendly and breathable material. Light-colored Lycra fabric can be used to observe whether it is dirty and whether it needs to be replaced, making it more comfortable to use.
[0030] In the specific implementation process, such as Figure 3 , Figure 6 and Figure 7 As shown, the light-emitting device 154 and the receiving device 155 are symmetrically arranged on a pair of flexible FPC boards 152. The light-emitting device 154 on the right is offset vertically by one millimeter from the receiving device 155 on the left.
[0031] In use, the light-emitting device 154 and the receiving device 155 are misaligned so that the light-emitting device 154 of the pulse oximeter probe 1 can directly face the receiving device 155, improving the accuracy of the measurement. Since the sole of the foot is flat and the back of the foot is sloping, the receiving sensor of the probe is attached to the foot, while the light-emitting device 154 needs to go around the thickness of the foot to the arched back of the foot. There is a deviation in curvature and angle between them, so the light-emitting device 154 needs to be misaligned by a certain distance to align with the receiving device 155. The light-emitting device 154 and the receiving device 155 are respectively located under a pair of transparent thin films 14.
[0032] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
