Description

Technical Field

[0001] This utility model relates to the field of blood oxygen saturation sensor technology, specifically to an improved pulse oxygen saturation sensor. Background Technology

[0002] Prior art application number 202020867549.1 discloses an improved pulse oximetry sensor, including a saturation sensor body. A retaining ring is fixedly installed on the rear surface of the saturation sensor body. An elastic wristband is engaged inside the retaining ring. A photosensitive detector is fixed at the middle position of the inner surface of the elastic wristband. A dual-emission tube is fixed on one side of the photosensitive detector on the inner surface of the elastic wristband. By designing the elastic wristband inside the retaining ring and designing a first protective sponge and a second protective sponge on the lower surface of the saturation sensor body and the elastic wristband, the sensor avoids the discomfort and inconvenience of directly sticking it to the wrist during use. It also avoids the side mounting of the detector head during use, which can cause inaccurate measurements. The elastic wristband can be inserted through the inside of the retaining ring, and the retaining ring can be fastened at the wrist position, allowing the dual-emission tube and the photosensitive detector to directly contact the skin for accurate detection of blood oxygen saturation.

[0003] The aforementioned improved pulse oximetry sensor has several issues during use, including: 1. The sensor uses an elastic wristband, but the tightness of the wristband cannot be adjusted. Wearing it too tightly can cause discomfort, while wearing it too loosely can lead to data inaccuracies and affect the judgment of medical personnel. 2. Because the saturation sensor and the elastic wristband are connected, the sensor can shift during user movement, affecting the accuracy of the measurement. Therefore, improvements are needed to address these issues. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] In view of the problems existing in the current blood oxygen saturation sensor, this utility model is proposed.

[0006] Therefore, the purpose of this invention is to provide an improved pulse oximetry sensor. The Velcro, through-hole, and rubber ring on the fixing strap enhance the stability and comfort of the sensor during wear.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] This utility model provides the following technical solution: an improved pulse oximetry sensor, which improves the stability and comfort of wearing the sensor by using Velcro, through holes, and rubber rings on the fixing strap. The user can adjust the tightness of the sensor according to their own conditions through the Velcro on the fixing strap, so as not to make the saturation sensor too tight or too loose. The through holes can adhere the medical tape to the user's skin, further improving the stability of the saturation sensor during wear, thereby ensuring the accuracy of the detection data.

[0028] The heating ring installed in the second annular groove can heat the detection position, preventing the detection position from being too cold and affecting the accuracy of the detection, which greatly improves the practicality compared with the existing technology.

[0029] Figs. 1-3 The diagram shown is a structural schematic of the first embodiment of an improved pulse oximetry sensor according to this utility model. Please refer to [link / reference]. Figs. 1-3 An improved pulse oxygen saturation sensor according to this embodiment includes a saturation sensor 100 body as its main body.

[0030] The saturation sensor 100 body includes a dual-emission light source 110 and a photodetector 120. The bottom of the saturation sensor 100 body is provided with a first annular groove 130 and a second annular groove 140. A rubber ring 150 is installed in the first annular groove 130 and a heating ring 160 is installed in the second annular groove 140. The top of the saturation sensor 100 is provided with a display screen 170 and a battery mounting slot 180. Fixing straps 200 are provided on both sides of the saturation sensor 100. The ends of the fixing straps 200 are provided with Velcro 210. A through hole 220 is provided in the middle of the fixing straps 200.

[0031] There are several dual-emission light sources 110, which are evenly distributed at the center of the bottom of the saturation sensor 100 body. There are several photodetectors 120, which are evenly distributed in two rings at the bottom of the saturation sensor 100 body. A button battery is installed in the battery mounting slot 180. The heating ring 160 and the rubber ring 150 are higher than the bottom of the saturation sensor 100 body. Medical tape is adhered to the through hole 220 and the medical tape is adhered to the user's skin through the through hole 220.

[0032] The saturation sensor 100 emits light waves of a certain wavelength, such as green light, onto the skin through dual emission light sources 110. Since the absorption rate of light by blood vessels is different during the pulse, the light reflected back through the skin tissue is received by the photodetector 120, converted into an electrical signal and digitized. Based on the light absorption rate of the blood, the heart rate can be calculated, thereby obtaining the user's pulse and blood oxygen saturation.

[0033] The first annular groove 130 is used to support the rubber ring 150, which is used to contact the user's skin. Since the rubber ring 150 is made of a relatively soft material, it can increase the user's comfort. The second annular groove 140 is used to support the heating ring 160, which can heat the detection area and prevent the detection location from being too cold, thus affecting the accuracy of the detection. The display screen 170 is used to display the data after detection. The battery mounting slot 180 is used to support the button battery, which is used to provide power. The fixing strap 200 is used to fix the saturation sensor 100 body to prevent the saturation sensor 100 body from shifting during the detection process, thereby affecting the accuracy of its data. It includes Velcro 210 and through hole 220. Velcro 210 is used to connect the fixing straps 200 at both ends to fix it to the wrist, ankle, or other parts. Through hole 220 is used to fix the blood oxygen sensor body to the user's skin when Velcro 210 cannot be used.

[0034] The Velcro 210, through-hole 220, and rubber ring 150 on the fixing strap 200 can improve the stability and comfort of the saturation sensor 100 when worn. The user can adjust the tightness of the strap according to their own conditions through the Velcro 210, so that the saturation sensor 100 is not worn too tightly or too loosely. The through-hole 220 can bond the medical tape to the user's skin, further improving the stability of the saturation sensor 100 when worn, thereby ensuring the accuracy of the data during detection.

[0035] The heating ring 160 installed in the second annular groove 140 can heat the detection position, preventing the detection position from being too cold and affecting the accuracy of the detection, which greatly improves the practicality compared with the existing technology.

[0036] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
