Description

Technical Field

[0001] The present invention relates to the technical field related to blood oxygen analysis devices, and in particular to a portable blood oxygen analysis device for mobile health examinations. Background Art

[0002] Measuring blood oxygen helps to understand the body's oxygen supply, improve health awareness and prevent diseases. Blood oxygen saturation refers to the ratio of oxygen to hemoglobin in the blood, which reflects the body's oxygen supply. Measuring blood oxygen can detect hypoxemia in time and increase sensitivity to the patient's condition. Therefore, if blood oxygen measurement can be performed during outdoor activities, it can help people detect hypoxia in time and avoid discomfort symptoms such as fatigue and dizziness.

[0003] At present, portable blood oxygen analysis devices (i.e., blood oximeters) on the market generally use light emission modules to emit two light beams of different wavelengths to detect deoxyhemoglobin and oxygenated hemoglobin. However, in addition to deoxyhemoglobin and oxygenated hemoglobin, the human body also has other hemoglobins, such as the common carboxyhemoglobin. Therefore, only detecting deoxyhemoglobin and oxygenated hemoglobin will not meet the health monitoring that users are increasingly paying attention to. In addition, only detecting deoxyhemoglobin and oxygenated hemoglobin under two wavelengths of light beams without other wavelengths of light for comparison will also fail to meet users' needs for higher-precision blood oxygen measurement. Summary of the invention

The matching cylinder is installed on the back of the wedge-shaped clamping body. One end of it is provided with a universal plug electrically connected to the light emission module or the light receiving module, and a support spring connecting the wedge-shaped clamping body and the inner wall of the support body is also sleeved outside it;

The elastic adaptor includes a strengthening part connected to the universal port and two V-shaped connecting parts connected to the strengthening part through arc parts. The V-shaped connecting parts can be folded, and one end of it is connected with an installation part through an arc part.

[0013] As a preferred technical solution of the present invention, the bottom of the detection chamber is symmetrically provided with wire passing holes I. One side of the wire passing holes I is provided with a U-shaped bracket for installing the elastic adaptor, and the U-shaped bracket is arranged inside the detection chamber.

[0014] As a preferred technical solution of the present invention, the constraint component includes a fixing ring for connecting with the end cap and an annular constraint airbag connected to the inner wall of the fixing ring. A pressing inflation valve I is provided through the annular constraint airbag.

[0015] As a preferred technical solution of the present invention, the support unit further includes two straps with adjustable lengths. The two straps are connected by a buckle.

[0016] As a preferred technical solution of the present invention, two press-inflation valves are provided through the support airbag, and two connecting straps for connecting the hanging straps are provided on the top of the support airbag.

[0017] As a preferred technical solution of the present invention, a rechargeable battery is provided in the control compartment, and the battery is electrically connected to the control module and the control motor respectively through wires.

[0018] The beneficial effects of the present invention are:

[0019] 1. This portable blood oxygen analysis device for mobile health check-up can not only compare the contents of deoxyhemoglobin and oxygenated hemoglobin detected under red light and infrared light of different wavelengths by switching the blood oxygen detection component, but also detect other hemoglobins, such as carboxyhemoglobin, thereby meeting the user's demand for higher-precision blood oxygen measurement. The coordinated use of the blood oxygen detection component and the adaptive component can not only make the elastic pad fit the detection finger more closely, but also limit the detection finger, which can effectively avoid inaccurate detection results caused by finger movement and further improve detection accuracy.

[0020] 2. This portable blood oxygen analyzer for mobile health examination can be hung around the neck or across the shoulder with a strap, and the human body is used as a support for the blood oxygen analyzer. There is no need to carry a table, bracket or other supporting device to support the blood oxygen analyzer. During the test, the forearm is supported by the support plate and the support airbag, which can prevent inaccurate test results caused by the difficulty in maintaining the test posture due to the lack of support for the arm. The support airbag can not only adapt to different arms, but also improve comfort.

[0021] 3. This portable blood oxygen analysis device for mobile health examination can inflate and deflate the annular restraint airbag by pressing the inflation valve 1. The inflated annular restraint airbag can well wrap the detection fingers of different thicknesses, and position and support the detection fingers, effectively preventing the fingers from moving or shaking, and can also effectively isolate the influence of external ambient light on the detection, further improving the detection accuracy.

[0022] 4. For this portable blood oxygen analysis device for mobile health checkup, after the universal plug is inserted into the universal port, due to the different thicknesses of different detection fingers, the V-shaped connecting part will be folded to different degrees due to pressure, which is very conducive to the V-shaped clamp to fit with fingers of different thicknesses.

[0023] 5. In this portable blood oxygen analysis device for mobile health checkup, the universal port does not rotate with the switching of the blood oxygen detection components, thereby avoiding the occurrence of tangling. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0038] Embodiment: As Figure 1-4 shown, a portable blood oxygen analysis device for mobile health examination of the present invention includes a support unit 1, which is composed of a support airbag 12 that can adapt to different arms and a support plate 13 for supporting the support airbag 12; the forearm is supported by the support plate 13 and the support airbag 12 to prevent inaccurate detection results caused by the difficulty of maintaining the detection posture unchanged due to the lack of support for the arm, and the support airbag 12 can not only adapt to different arms, but also improve comfort; if it is necessary to prevent the arm from moving, a strap that can tie the forearm can be provided on the support airbag 12;

[0039] A blood oxygen analysis unit provided at one end of the support unit 1, which includes a housing composed of a detection chamber 5, a control chamber 6 connected to one end of the detection chamber 5, and an end cap 4 connected to the other end of the detection chamber 5. A control module is installed in the control chamber 6. Two adaptive components are arranged face to face in the detection chamber 5. A blood oxygen detection module 8 is provided in the housing. The blood oxygen detection module 8 includes at least two groups of blood oxygen detection components 83 that can perform dual-wavelength detection. The blood oxygen detection components 83 are electrically connected to the control module through the adaptive components, and the housing is connected to the support plate 13 through the adjustment bracket 3. The adjustment bracket 3 can adjust the height of the blood oxygen analysis unit and the distance from the support plate 13, which is beneficial to meeting the use requirements of different people;

[0040] A restraint component provided at one end of the end cap 4 can position and restrain the detection finger.

[0041] In addition, the blood oxygen analysis unit further includes a display module and a power button of the wake-up device that are electrically connected to the control module. The display module is used to display blood oxygen detection data, and the power button is used to start and stop the device. The specific structures and installation positions of the display module and the power button are not limited herein, so they are not marked in the drawings. For example, both the display module and the power button are arranged through the control chamber 6.

[0042] Among them, Figure 5-9 As shown, the blood oxygen detection module 8 also includes a control motor 82 installed in the control compartment 6. The output end of the control motor 82 is connected to a cylindrical support body 81. The support body 81 is provided with a plurality of matching holes. After the control motor 82 is started, it will drive the support body 81 to switch the blood oxygen detection component 83 through the rotation of the support body 81.

[0043] The blood oxygen detection component 83 includes two wedge-shaped clamping bodies 831 arranged face to face, an elastic pad 833 arranged on the inclined surface of the wedge-shaped clamping body 831 and capable of adapting to fingers, a matching tube 832 slidably matched with the matching hole, a light emitting module capable of emitting light of two different wavelengths, and a light receiving module capable of receiving light from the light emitting module. The light emitting module can be capable of emitting 650nm red light and 910nm infrared light, or can be capable of emitting 650nm red light and 920nm infrared light, and can detect deoxyhemoglobin and oxygenated hemoglobin; the light emitting module can also be capable of emitting light of 500nm and 550nm wavelengths, and can detect carboxyhemoglobin. Therefore, by switching the blood oxygen detection component 83, not only can the comparison be performed, but also the detection of deoxyhemoglobin and oxygenated hemoglobin can be performed. The contents of deoxyhemoglobin and oxygenated hemoglobin detected under red light and infrared light of different wavelengths can also be used to detect other hemoglobins, such as carboxyhemoglobin when the light emitting module emits light of 500nm and 550nm wavelengths. The matching cylinder 832 is installed on the back of the wedge-shaped clamping body 831, and one end of the cylinder is penetrated by a universal plug 834 electrically connected to the light emitting module or the light receiving module, and the outside of the cylinder is also provided with a support spring 835 connected to the wedge-shaped clamping body 831 and the inner wall of the support body 81; the two wedge-shaped clamping bodies 831 and the elastic pads 833 thereon form a V-shaped clamping piece, which is convenient for fitting with fingers of different thicknesses; the specific number of blood oxygen detection components 83 can be set according to actual usage requirements, but at least two groups are required.

[0044] The wedge-shaped clamping body 831 is provided with an installation cavity for installing a light emitting module or a light receiving module, and a light-transmitting window for sealing the installation cavity is installed at one end of the installation cavity. The setting of the light-transmitting window is conducive to the emission and reception of light, and the elastic pad 833 is also provided with an accommodating hole for accommodating the light-transmitting window. The elastic pad 833 in contact with the detecting finger can improve comfort.

[0045] After switching the blood oxygen detection component 83, insert the detection finger into the housing. By pressing the elastic pad 833 with the detection finger, the wedge-shaped clamping body 831 drives the fitting cylinder 832 to move towards the adaptive component. The fitting cylinder 832 drives the universal plug 834 to insert into the universal port 10, completing the connection between the universal plug 834 and the universal port 10. The elastic force of the support spring 835 makes the elastic pad 833 fit more closely with the detection finger, which is beneficial to improving the detection accuracy. And after pulling out the finger, the wedge-shaped clamping body 831 can reset by the elastic force of the support spring 835, and the universal plug 834 can also be disengaged from the universal port 10 to disconnect the connection;

[0046] The unused blood oxygen detection component 83 is used to limit the detection finger, which can effectively avoid inaccurate detection results caused by the finger moving randomly.

[0047] In addition, a weight-reducing hole is also provided on the wedge-shaped clamping body 831 to reduce the weight of the wedge-shaped clamping body 831.

[0048] Among them, as Figure 4 、 Fig.10 and Fig.11 shown, the adaptive component consists of a universal port 10 that can be inserted and matched with the universal plug 834 and an elastic adaptor 9 for supporting the universal port 10. The universal port 10 does not rotate with the switching of the blood oxygen detection component 83, so the situation of wire winding can be avoided. The universal port 10 is electrically connected to the control module through a wire. The elastic adaptor 9 includes a strengthening part 91 connected to the universal port 10 and two V-shaped connecting parts 92 connected to the strengthening part 91 through arc-shaped parts. The V-shaped connecting part 92 can be folded, and one end thereof is connected with an installation part 93 through an arc-shaped part; a through hole for allowing the wire to pass through is provided on the strengthening part 91, which is beneficial to wire connection.

[0049] Due to the different thicknesses of different detection fingers, after the universal plug 834 is inserted into the universal port 10, the V-shaped connecting part 92 will be folded to different degrees due to pressure, so it is very beneficial for the V-shaped clamping part to fit with fingers of different thicknesses.

[0050] Among them, as Figure 4 and Fig.10 shown, the bottom of the detection bin 5 is symmetrically provided with a first wire passing hole, and the first wire passing hole can allow the wire connecting the universal port 10 to pass through the detection bin 5. A U-shaped bracket 7 for installing the elastic adaptor 9 is provided on one side of the first wire passing hole. The U-shaped bracket 7 is arranged inside the detection bin 5, and an avoidance opening is provided on the U-shaped bracket 7 to facilitate the wire connecting the universal port 10 to pass through the first wire passing hole.

[0051] Among them, as Figure 2 and Figure 3As shown, the constraint assembly includes a fixing ring connected to the end cover 4 and an annular constraint airbag 2 connected to the inner wall of the fixing ring. A press-inflatable valve 21 is provided through the annular constraint airbag 2. The annular constraint airbag 2 can be inflated and deflated by pressing the inflation valve 21. The inflated annular constraint airbag 2 can well wrap the detection fingers of different thicknesses, and position and support the detection fingers, effectively preventing the fingers from moving around or shaking, and can also effectively isolate the influence of external ambient light on the detection, further improving the detection accuracy.

[0052] Among them, Figure 1 and Figure 2 As shown, the support unit 1 also includes two straps 11 of adjustable length, which are connected by buckles. The blood oxygen analyzer can be hung around the neck or across the shoulders by means of the provided straps 11, and the human body is used as a support for the blood oxygen analyzer. There is no need to carry supporting devices such as tables and brackets for supporting the blood oxygen analyzer. A soft pad 14 is sleeved on one of the straps 11. The soft pad 14 is relatively wide and soft as a part in contact with the neck or shoulder, which can improve comfort. The soft pad 14 is bonded and connected to the Velcro fur surface on the strap 11 via a Velcro hook surface. The soft pad 14 can slide along the strap 11 to adjust its position, which is suitable for people with different arm lengths. The soft pad 14 can be fixed by bonding the Velcro hook surface to the Velcro fur surface to avoid displacement of the soft pad 14 due to neck twisting and the like.

[0053] The support airbag 12 is provided with a second push-in inflation valve, and the top of the support airbag 12 is provided with two connecting straps for connecting the hanging strap 11 . The support airbag 12 is inflated and deflated by pressing the second inflation valve.

[0054] Among them, Figure 4 As shown, a rechargeable battery is provided in the control compartment 6, and the battery is electrically connected to the control module and the control motor 82 through wires. The battery supplies power to drive the light emitting module to emit light through the control module. The control module can also receive electrical signals from the light receiving module and process and analyze the electrical signals to obtain blood oxygen detection results.

[0055] In addition, the control compartment 6 is provided with a second threading hole for allowing the wire to pass through; the second threading hole allows the wire connected to the universal port 10 to enter the control compartment 6 and connect to the control module; the control compartment 6 is also provided with a charging interface electrically connected to the battery for charging the battery.

[0056] When working, press the second inflation valve to inflate the support airbag 12, use the hanging strap 11 to hang the blood oxygen analyzer around the neck or across the shoulder, use the human body as the support of the blood oxygen analyzer, and place the forearm on the support airbag 12. After the finger to be tested is inserted into the shell, the annular constraint airbag 2 is inflated by pressing the inflation valve 1 21. The inflated annular constraint airbag 2 can wrap the detection finger well and position and support the detection finger. The detection finger presses the elastic pad 833 to make the wedge-shaped clamping body 831 move with the matching tube 832 toward the adaptive component. The matching tube 832 is inserted into the universal port 10 with the universal plug 834. After pressing the power button, the device is awakened, and the light emitting module is driven by the control module to emit light. The light passes through the finger and is received by the light receiving module. Then the light receiving module sends an electrical signal to the control module, and the control module processes and analyzes the electrical signal from the light receiving module to finally obtain the blood oxygen detection result.

[0057] After one test is completed, the testing finger is pulled out, and the control motor 82 is started. The control motor 82 drives the rotation of the support body 81 to switch the blood oxygen detection component 83, and then the test is performed. By switching the blood oxygen detection component 83, not only can the contents of deoxyhemoglobin and oxygenated hemoglobin detected under red light and infrared light of different wavelengths be compared, but other hemoglobins, such as carboxyhemoglobin, can also be detected.

[0058] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
