Description

Technical Field

[0001] This utility model relates to the field of monitoring equipment technology, and in particular to a connecting strap for a wrist monitor. Background Technology

[0002] A pulse oximeter and blood pressure monitor are used to detect the concentration and pressure of blood within the human body. Pulse oximetry checks the oxygen concentration in the blood, while blood pressure is measured at both systolic and diastolic pressures. Generally, normal blood oxygen saturation is 95%-100%. Higher blood oxygen levels correlate with higher metabolic efficiency and better health. However, excessively high blood oxygen levels are not ideal, as the body has a certain saturation point. Too high levels can accelerate cell aging, while too low levels can lead to insufficient oxygen supply and health problems. Therefore, it is necessary to regularly monitor blood oxygen and blood pressure using a pulse oximeter and blood pressure monitor to monitor changes in health.

[0003] For example, a wrist-type multifunctional monitor with publication number CN204765590U includes a wristband and a monitor. The monitor is glued and fixed to the wristband, which forms a closed loop structure adapted to the human wrist through a fixing adhesive strip. A blood oxygen sensor, a body temperature sensor, and an ECG touch electrode are located on the side of the wristband near the wrist. An air bladder is located inside the wristband. The monitor has a display screen and function switches, and contains a battery, an inflation pump, a deflation valve, and functional circuitry. This device integrates various electrodes and sensors for ECG, non-invasive blood pressure, blood oxygen saturation, body temperature, respiration, and pulse, and can monitor and transmit six vital signs data in real time. It is small, lightweight, easy to wear, and simple to use. It can also issue alarms via a voice module when parameters are abnormal or the wearer's health is at risk, and transmit data wirelessly to a corresponding smart terminal or PC via Bluetooth.

[0004] In summary, the following technical problems exist in the existing technology: the existing wearable blood oxygen and blood pressure monitors are not securely fixed when worn. Utility Model Content

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] Reference Figures 1-6 A connecting strap for a wrist monitor includes a dial 1, a display screen 2 inside the top of the dial 1 to display the detected data, a protective plate inside the bottom of the dial 1, the protective plate being made of acrylic, a blood pressure sensor and a blood oxygen sensor inside the dial 1 and on top of the protective plate, so that the light emitted by the blood pressure sensor and blood oxygen sensor during detection can be emitted outward through the acrylic protective plate;

[0029] In this embodiment, the display screen 2 has a mature and widespread application in the field of network information display, and will not be described in detail in this embodiment. The blood pressure sensor and the blood oxygen sensor are both mature existing mechanisms. The blood pressure sensor is used to sense blood pressure and convert it into a usable output signal, and the blood oxygen sensor is used to sense the partial pressure of oxygen in the blood and convert it into a usable output signal.

[0030] One end of the dial 1 is fixed with a first fixing strap 3, and the other end of the dial 1 is fixed with a second fixing strap 4. The end of the second fixing strap 4 away from the dial 1 is fixed with a fixing shell 5. The top of the fixing shell 5 is fixed with a photoelectric receiver 8. The inside of the fixing shell 5 and the top of the photoelectric receiver 8 is fixed with a transparent plate 9. The transparent plate 9 is also made of acrylic, so that the light emitted by the blood pressure sensor and the blood oxygen sensor can be received by the photoelectric receiver 8.

[0031] In this embodiment, the photoelectric receiver 8 is an existing mature device with mature applications in the fields of blood pressure and blood oxygen detection. It measures the light emitted by the blood pressure sensor and blood oxygen sensor by measuring the sensitivity and transmittance of oxygen and hemoglobin to light. As the pulse lengthens or contracts, when blood passes through the circulatory extremities, the oxygen content is measured by light irradiation. The transmittance is received by the photoelectric receiver 8. Based on the transmittance and a certain algorithm, the oxygen saturation or blood pressure is calculated and then displayed on the display screen 2.

[0032] The fixed shell 5 is also equipped with a positioning mechanism for connecting the first fixing band 3. The positioning mechanism includes a rotating column 13, a positioning block 15, and a second return spring 16. The outer side of the top of the rotating column 13 is rotatably connected to the fixed shell 5, so that the rotating column 13 can rotate inside the fixed shell 5. The outer side of the bottom of the rotating column 13 is slidably connected to the first fixing band 3. A sliding groove is opened on the inner side of the rotating column 13, and the rotating column 13 and the first fixing band 3 are slidably connected through the sliding groove. Positioning blocks 15 are slidably connected to the inner sides of the bottom of the rotating column 13. The bottom of the two positioning blocks 15 is inclined at one end away from each other, so that when the positioning blocks 15 are squeezed, they can be driven to move into the interior of the rotating column 13 through the inclined surface. The second return spring 16 is set inside the rotating column 13 and between the two positioning blocks 15, so that when the positioning blocks 15 move into the interior of the rotating column 13, they squeeze the second return spring 16. The rebound of the second return spring 16 after compression drives the two positioning blocks 15 to return to their original position.

[0033] The slide groove consists of a first positioning groove 6 and two second positioning grooves 7. The two ends of the first positioning groove 6 are connected to the second positioning grooves 7, so that the first positioning groove 6 and the second positioning groove 7 pass through to form a whole. This allows the rotating column 13 to drive the positioning block 15 to rotate 90 degrees and then disengage from the first fixing belt 3 through the slide groove.

[0034] The interior of the fixed shell 5 is also equipped with a rotating assembly for driving the rotating column 13 to rotate. The rotating assembly includes a pressing plate 10, a transmission rack 11, a first return spring 12, and a transmission gear 14. The pressing plates 10 are slidably connected to the interior of both ends of the fixed shell 5. The transmission gear 14 is fixed to the outside of the rotating column 13 and inside the fixed shell 5. The transmission rack 11 is meshed with both sides of the transmission gear 14. The transmission rack 11 is fixed to the pressing plate 10, so that when one of the pressing plates 10 is pressed, it can drive one of the transmission racks 11 to move. The first return spring 12 is fixed to one end of one of the transmission racks 11 near the other pressing plate 10, and one end of the first return spring 12 is fixed to the other pressing plate 10, so that when the pressing plate 10 is pressed, it can drive the transmission gear 14 to rotate through the transmission rack 11, and when there is no external force, the transmission rack 11 is reset and moved by the reset after being compressed by the first return spring 12.

[0035] In another embodiment, the number of the extrusion plate 10, the transmission rack 11, and the first return spring 12 may all be one, thereby enabling the transmission gear 14 to rotate through the extrusion of a single extrusion plate 10.

[0036] In summary:

[0037] This utility model addresses the technical problem that existing wearable pulse oximeter and blood pressure monitors are not securely fixed during use; it employs the technical solutions described in the above embodiments. Furthermore, the implementation process of the above technical solutions is as follows:

[0038] When the detector needs to be worn, it is fixed to the outer side of one wrist by the second fixing strap 4, conforming to the wrist skin. Then, the first fixing strap 3 is fixed to the outer side of the other wrist and contacts the fixing shell 5. Then, the first fixing strap 3 slides on the outside of the positioning block 15 through the sliding connection between the rotating column 13 and the fixing shell 5. At the same time, the compression of the first fixing strap 3 causes the bottom inclined surface of the positioning block 15 to be compressed, which in turn causes the positioning block 15 to slide inside the rotating column 13. The movement of the two positioning blocks 15 compresses the second return spring 16. Then, when the positioning block 15 enters the interior of the rotating column 13, the first fixing strap 3 slides on the outside of the rotating column 13, so that the first fixing strap 3 is located at the top of the positioning block 15. At this time, the reset caused by the compression of the second return spring 16 causes the positioning block 15 to move outward. The outward movement of the positioning block 15 affects the second return spring 16. A fixing band 3 is fixed on the outside of the rotating column 13. When the first fixing band 3 needs to be removed from the rotating column 13, the pressing plate 10 is pressed to move the pressing plate 10 into the fixed shell 5. The movement of the pressing plate 10 drives the transmission rack 11 to move. The movement of the transmission rack 11 drives the meshing transmission gear 14 to rotate. The rotation of the transmission gear 14 drives the rotating column 13 to rotate. At the same time, the movement of the transmission rack 11 presses the first return spring 12. The rotation of the rotating column 13 drives the positioning block 15 to rotate 90 degrees so that the position of the positioning block 15 is the same as the position of the second positioning groove 7. Then, the first fixing band 3 is pulled to remove the first fixing band 3 from the rotating column 13. When the pressing plate 10 is released, the first return spring 12 can reset the rotating column 13 to rotate 90 degrees. At this time, the position of the positioning block 15 is perpendicular to the position of the second positioning groove 7.

[0039] With the above-mentioned settings, this application will certainly solve the above-mentioned technical problems, and at the same time achieve the following technical effects:

[0040] Through the cooperation of the first fixing strap 3, the fixing shell 5, the rotating column 13, the positioning block 15, and the second return spring 16, the first fixing strap 3 can be tightly fitted with the second fixing strap 4 and then fixed to the second fixing strap 4, so that the dial 1 can be securely worn on the outside of the user's wrist.

[0041] Through the cooperation of the pressing plate 10, the transmission rack 11, the first return spring 12 and the transmission gear 14, the rotation of the rotating column 13 can drive the positioning block 15 to rotate 90 degrees, thereby separating the first fixing belt 3 and the second fixing belt 4.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
