Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

The embodiment of the application provides a blood oxygen detector. The main measurement indexes of the oximeter are pulse rate, oxygen saturation (abbreviated as SpO2), and Perfusion Index (PI), respectively. Blood oxygen saturation is one of the clinically important basic data. Oxygen saturation refers to the percentage of the bound O2 volume in total blood volume to the total bindable O2 volume.

Fig. 1 is a schematic perspective view of an oximeter in accordance with an embodiment of the present invention, and fig. 2 is a schematic exploded view of the oximeter shown in fig. 1. As shown in fig. 1 and fig. 2, the blood oxygen detector in the embodiment of the present invention is a portable blood oxygen detector, has a small structure, and has a body-integrated feature, wherein the body-integrated feature specifically means that a blood oxygen probe of the blood oxygen detector and the body are integrated together, so as to reduce the volume of the whole blood oxygen detector and improve the portability of the blood oxygen detector. The blood oxygen saturation detector can be conveniently worn on the body, so that the blood oxygen saturation of the human body can be detected.

As shown in fig. 1 and 2, the blood oxygen detector in one embodiment is shaped like a ring, and can be worn on a finger to continuously detect the blood oxygen saturation value of a human body for a long time. This blood oxygen detector small in size, convenient to use, in order to improve blood oxygen detector's performance, for example make people normally wear in humid environment such as rainy day, require blood oxygen detector to have good waterproof performance. Of course, in other embodiments, the blood oxygen detector in the present application may also not be limited to the ring shape, and for example, may also be wearable such as a bracelet. Introduce with the blood oxygen detector of ring molding in the embodiment of this application, the technical personnel in the field can be according to the record of embodiment, and the corresponding is made a change the ring molding into models such as bracelet.

The oximeter in one embodiment of the present invention includes a main housing 100, a circuit module 200, and an outer cover 300. As shown in fig. 3, fig. 3 is a schematic structural diagram of the main housing 100 in an embodiment of the present invention, the main housing 100 includes a main body portion 110 and an inner cover 120 connected to the main body portion 110, an inner cavity 140 is disposed in the main body portion 110, and the inner cover 120 is used for covering an opening of the inner cavity 140. An opening groove 130 is formed between the edge of the inner cap 120 and the main body 110. Specifically, one end of the inner cap 120 is connected to the main body 110, and an open slot 130 is formed between the other end of the inner cap 120 and the main body 110. The inner cover 120 and the main body 110 may be integrally formed or may be fixedly connected by glue. The inner cover 120 can be opened from the open slot 130 to place the circuit module 200 into the inner cavity 140. That is, the inner cover 120 is made of at least a flexible material, the state shown in fig. 3 is a state where the inner cover 120 is opened, and when the inner cover 120 is opened, the opening of the inner cavity 140 is exposed, so that the circuit module 200 can be installed in the inner cavity 140 from the opening of the inner cavity 140. The inner cover 120 is then resealed over the opening of the interior cavity 140. In this embodiment, since the inner cavity 140 communicates with the outside through the elongated opening groove 130, rather than communicating with the outside through the opening of the entire inner cavity 140, the outer cap 300 is connected to the main housing 100 and at least seals the opening groove 130, thereby reducing the sealing range and improving the sealing performance.

Specifically, as shown in fig. 2 and 3, the inner cover 120 and the main body 110 are both made of a rubber material, and the inner cover 120 is integrally formed with the main body 110. The opening of the inner cavity 140 is substantially rectangular or circular in shape, etc. When the opening of the inner cavity 140 is rectangular, the connecting portion 173 of the inner cover 120 and the main body 110 is located at one side of the rectangle, and the opening groove 130 extends along the other three sides of the rectangle. The open groove 130 is a long and narrow slit which is bent and thus facilitates sealing of the long and narrow slit by glue. Sealing can be done in two ways. For example, after the circuit module 200 is mounted in the inner cavity 140, glue is applied to the outer surface of the main housing 100 near the open slot 130, and then the outer cover 300 is adhered to the main housing 100. For another example, after the circuit module 200 is installed in the inner cavity 140, glue is applied in the open slot 130, and after the glue is solidified, a sealant is formed in the open slot 130, so that even if the inner cover 120 is not installed, the open slot 130 can be sealed by the sealant; to further improve the sealing effect, glue may be continuously applied to the outer surface of the main housing 100 near the open slot 130, and then the outer cover 300 is adhered to the main housing 100; therefore, the double sealing effect can be achieved through the sealing glue and the outer sealing cover 300, and the blood oxygen detector has better sealing performance.

It should be noted that, besides the glue can be applied to the outer surface of the outer cap 300 near the open slot 130, the application area of the glue can also be enlarged, so that the glue is applied to the area where the outer cap 300 contacts the main body 110, thereby further improving the sealing effect. It should be noted that the glue is applied to the outer surface of the outer cover 300 and near the open slot 130, specifically, the glue is applied to the outer surface of the outer cover 300, and the glue application area forms a closed circle around the open slot 130, so that the open slot is separated from the outside by the glue, and a sealing effect is formed.

Fig. 4 is a perspective view of another view of the blood oxygen detector in an embodiment of the present invention. In one embodiment, the blood oxygen measuring device has a contact slot 111 disposed in the body portion 110 for communicating the outside with the inner cavity 140, and the circuit module 200 includes electrical contacts disposed in the contact slot 111. It should be noted that the above-mentioned external environment is relative to the inner cavity 140, and the space outside the inner cavity 140 of the oximeter is referred to as the external environment. For example, in the embodiment shown in fig. 4, there are four contact slots 111, and there are four corresponding electrical contacts, two electrical contacts being used to charge the oximeter, and two electrical contacts being used to transmit data. It should be understood that although the contact groove 111 communicating with the inner cavity 140 is provided on the body portion 110, the electrical contact is inserted into the contact groove 111, and the outer peripheral wall of the electrical contact is fitted to the inner wall of the contact groove 111, which can perform a sealing function. In addition, a sealant may be provided at a portion where the outer peripheral wall of the electrical contact is attached to the contact groove 111, thereby performing a sealing function to prevent moisture from entering the inner cavity 140.

It should be understood that processor 210 serves as a core electrical component of the oximeter, and serves as a comprehensive control for the other electrical components of the oximeter. For example, the battery 220 and the electrical contacts are electrically connected to the processor 210, and when the battery 220 is charged through the electrical contacts, the processor 210 can intelligently analyze the charging time to reduce the charging current after the battery 220 is fully charged to protect the battery 220.

In one embodiment, as shown in fig. 5, the circuit module 200 includes a processor 210, and a wireless charging coil 250, a battery 220 and an oximetry sensor 230 electrically connected to the processor 210, wherein the processor 210 is used for analyzing and processing the data detected by the oximetry sensor 230. In this embodiment, the electrical contact in the above-mentioned embodiment is replaced by the wireless charging coil 250, so that the main body 110 in this embodiment does not have to be provided with the contact slot 111 communicating with the inner cavity 140, thereby further improving the sealing performance of the inner cavity 140 and improving the waterproof performance of the blood oxygen detector.

Wireless charging coil 250 is attached to first surface 271 of PCB board 270 by double-sided adhesive tape 280 and battery 220 is attached to second surface 272 of PCB board 270 by double-sided adhesive tape 280. The Circuit module 200 further includes an FPC board 290, wherein the FPC board 290 is also called a Flexible Printed Circuit (FPC) board, which is a Flexible Printed Circuit board having high reliability and excellent performance and is made of polyimide or polyester film as a base material. The high-density light-weight LED lamp has the characteristics of high wiring density, light weight, thin thickness and good bending property. The blood oxygen sensor 230 is electrically connected to the FPC 290, and the FPC 290 is electrically connected to the PCB 270. The FPC board 290 has two flexible branches 291, and each branch 291 is provided with the blood oxygen sensor 230.

Further, as shown in fig. 5, the circuit module 200 further includes a buzzer 260, and the buzzer 260 is electrically connected to the processor 210. When the blood oxygen saturation data detected by the blood oxygen sensor 230 is smaller than the preset threshold, the buzzer 260 makes a sound to remind the wearer in time. Of course, circuit module 200 also can be provided with the bluetooth unit, makes blood oxygen detector electric connection cell-phone end through the bluetooth unit, can operate on the APP of cell-phone end to control blood oxygen detector. For example, the time for starting the buzzer 260 can be controlled on the APP of the mobile phone end, and the buzzer 260 is not started in the sleep stage under control, so as to prevent the buzzer 260 from sounding to affect the sleep of the wearer.

In addition, the blood oxygen saturation data obtained by the processor 210 can be displayed through the APP at the mobile phone end. In some embodiments, as shown in fig. 5, the circuit module 200 may also include a display screen 240 electrically connected to the processor 210, wherein the display screen 240 is used for displaying the blood oxygen saturation data obtained by the processor 210. Further, referring to fig. 2 and 3, the inner cover 120 is provided with a display slot 121 for installing the display screen 240, and the content displayed on the display screen 240 can be conveniently viewed through the display slot 121. Further, the outer cover 300 may cover the display screen 240, and particularly, the outer cover 300 covers the display slot 121. The outer cover 300 may be made of a transparent material so that the contents of the display screen 240 can be viewed through the outer cover 300.

As shown in fig. 6, fig. 6 is a schematic cross-sectional structure view of the main body 110 in an embodiment of the invention. The main body 110 is provided with a finger cavity 150 for wearing on a finger, the main body 110 is provided with a window 160 communicating the finger cavity 150 and the inner cavity 140, and the blood oxygen sensor 230 is arranged at the window 160. The body portion 110 includes a first wrap 171 and a second wrap 172, and the internal cavity 140 extends to the first wrap 171 and the second wrap 172, respectively. Further, the inner cavity 140 includes a main cavity 143 and a first cavity 141 and a second cavity 142 connecting the main cavity 143, the first cavity 141 extends to the first wrapper 171, and the second cavity 142 extends to the second wrapper 172. Referring to fig. 5, FPC board 290 has two flexible legs 291, each leg 291 having an oximetry sensor 230 disposed thereon. One of the limbs 291 projects into the portion of the interior 140 extending into the first wrapper 171, i.e. the first cavity 141, and the other limb 291 projects into the portion of the interior 140 extending into the second wrapper 172, i.e. the second cavity 142. It should be appreciated that in order to improve the sealing of oximeter, the blood oxygen sensor 230 may be connected to the inner cavity 140 by glue sealing.

Referring to fig. 2, after the various electrical components of the circuit module 200 are assembled, the processor 210, the battery 220, the display screen 240, the wireless charging coil 250, the buzzer 260, and the PCB 270 may be disposed in the main housing 143. And two branches 291 of the FPC board 290 and the blood oxygen sensors 230 disposed on the branches 291 are disposed in the first and

second cavities

141 and 142, that is, one branch 291 and one blood oxygen sensor 230 are disposed in the first cavity 141 and one branch 291 and one blood oxygen sensor 230 are disposed in the second cavity 142. Referring to fig. 6, the first cavity 141 and the second cavity 142 are both elongated cavities, and the window 160 is disposed at the lower end of the elongated cavities, and the main cavity 143 is disposed at the upper end of the elongated cavities. Therefore, the window 160 is far from the main cavity 143, and even if moisture penetrates through the window 160, the moisture is difficult to reach the main cavity 143 through the long and narrow cavity, thereby ensuring that the electrical components in the main cavity 143 are not affected by damp. Further, a waterproof material may be filled in the first and

second cavities
