DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Specific embodiment 1 See also Figure 1-8The present invention is a multifunctional medical weight scale, comprising a base 1, a mounting groove 2 is provided inside the base 1, a weighing plate 3 is provided inside the mounting groove 2, a weighing sensor 4 is provided at the bottom of the weighing plate 3; an isolation component is provided inside the mounting groove 2, the isolation component comprises a bottom plate 5, the bottom plate 5 is slidably connected to the inside of the mounting groove 2, a bracket 6 is installed on the top of the bottom plate 5, a driving motor 7 is installed on the rear side of the bracket 6, a winding roller 8 is fixedly connected to the output end of the driving motor 7, an isolation film 9 is provided on the surface of the weighing plate 3, and the contact between the patient and the weighing plate 3 is isolated by the isolation component; a detection component is provided on the top of the base 1 The detection component includes a vertical frame 10, which is fixedly connected to the top of the base 1. A support plate 11 is installed on the rear side of the vertical frame 10. A near-infrared vein detector 12, a photoelectric sensor finger sleeve 13 and a body fat measuring instrument 14 are installed on the top of the support plate 11 respectively. The patient's physical condition is preliminarily checked through the detection component; a clamping component is provided on the front side of the bottom plate 5, and the clamping component includes a moving plate 15, which is fixedly connected to the front side of the bottom plate 5. A moving groove 16 is opened inside the moving plate 15, and a limit rod 17 is slidably connected inside the moving groove 16. The weighing sensor 4 is protected by the clamping component.

[0026] Specifically: the weighing sensor 4 includes multiple strain gauges, which are made of sensitive materials. When external weight is applied, the material will undergo a slight deformation, which will cause a change in the material's resistance. The resistance change sensed by the strain gauge will be converted into an electrical signal. After amplification and processing, the signal is displayed as a weight value, which can be used to measure the patient's weight. The isolation film 9 is made of medical polyethylene film, which can isolate the patient's feet from the weighing plate 3 and is scratch-resistant and wear-resistant. The winding roller 8, driven by the drive motor 7, can wind up the isolation film 9 to play a conveying role. Specific embodiment 2 See also Figure 1-8 On the basis of the specific embodiment 1, a top plate 18 is fixedly connected to the top of the weighing sensor 4, and telescopic rods 19 are fixedly connected to the four corners of the top plate 18. The top and bottom of the telescopic rod 19 are fixedly connected to the weighing plate 3 and the bottom plate 5 respectively. One side of the isolation film 9 is fixedly connected to the winding roller 8, and the bottom of the weighing sensor 4 is fixedly connected to the bottom plate 5. The detection component also includes a ruler 20, which is arranged on the front side of the vertical frame 10. An infrared height measuring instrument 21 is fixedly connected to the top of the vertical frame 10. A body temperature probe 22 is installed on the front side of the vertical frame 10. An ID card reader 23 is installed on the top of the support plate 11, and a display screen 24 is installed on the rear side of the vertical frame 10. One side of the photoelectric sensor finger sleeve 13 is fixedly connected to a reading device 25 through a wire, and the bottom of the reading device 25 is fixedly connected to the support plate 11.

[0028] Specifically: the near-infrared vein detector 12 emits near-infrared light of a specific wavelength and irradiates it onto the skin surface. The near-infrared light penetrates the skin, and part of the light is absorbed by components in tissues and blood, while the rest is scattered. By detecting the returned light signal, the instrument analyzes the degree to which light of different wavelengths is absorbed. Different components have different absorption characteristics for near-infrared light, thereby estimating the blood sugar level. The photoelectric sensor cuff 13 includes a light source and a photodetector. The light source emits light to the finger, and the detector receives light that is scattered or transmitted after penetrating the finger. Oxygenated hemoglobin (HbO2) and deoxygenated hemoglobin (Hb) in the blood have different absorption characteristics for light of different wavelengths. When the heart beats, blood flow causes changes in the amount of blood in the fingertips, thereby affecting the intensity of the transmitted light. By detecting these changes in light intensity, the device can monitor the ratio of oxygenated hemoglobin to deoxygenated hemoglobin in the blood in real time. Specific embodiment three See also Figure 1-8 On the basis of the specific embodiment 1, a handle 26 is fixedly connected to the front side of the support plate 11, and a conductive sheath 27 is sleeved on the surface of the handle 26. The rear side of the conductive sheath 27 is fixedly connected to the body fat measuring instrument 14 through a connecting line. A heating wire 28 is installed inside the weighing plate 3, and a material roller 29 is fixedly connected to the other side of the isolation membrane 9. The front and rear sides of the material roller 29 are movably connected to a support, and the bottom of the support is fixedly connected to the bottom plate 5. The clamping assembly also includes a nut 30, which is threadedly connected to the front side of the limit rod 17. A clamping groove 31 is opened on the front side of the movable plate 15, and a reset groove 32 is opened inside the movable plate 15. A clamping rod 33 is slidably connected inside the reset groove 32. A push plate 34 is fixedly connected to one side of the clamping rod 33, and a mounting hole 35 is opened inside the mounting groove 2. A spring 36 is sleeved on the surface of the clamping rod 33, and the two ends of the spring 36 are respectively fixedly connected to the push plate 34 and the inner wall of the reset groove 32.

[0030] Specifically: the front side of the body fat measuring instrument 14 is electrically connected to the conductive sheath 27 through a connecting wire. When the patient holds the conductive sheath 27, a weak alternating current can be sent to the body through the electrodes of the body fat measuring instrument 14. Because the conductivity of fat tissue is low, while the conductivity of muscle and water is high, the propagation speed and impedance of the current in different tissues will be different, so as to achieve the function of detecting body fat rate. The infrared height measuring instrument 21 can detect the height of the patient, the body temperature probe 22 can detect the body temperature of the patient, and the heating wire 28 can preheat the weighing plate 3. Heat can be generated to avoid irritation to the patient's feet in cold weather. The nut 30 is the same size as the snap-in slot 31. When the nut 30 is rotated and inserted into the snap-in slot 31, the position of the limit rod 17 can be fixed. The spring 36 has the function of compressing and storing energy, and can elastically reset the snap-in rod 33. When the limit rod 17 slides to the bottom of the movable slot 16, the support for the weighing plate 3 can be cancelled. When the limit rod 17 moves, the push plate 34 and the snap-in rod 33 can be pushed to move. When the snap-in rod 33 is inserted into the mounting hole 35, the movable plate 15 can be fixed.

[0031] The working principle of the present invention is as follows: when the patient stands on the top of the weighing plate 3, the weighing plate 3 transmits the weight to the weighing sensor 4, and the patient's weight is measured by the weighing sensor 4, and a start signal is output to the external controller at the same time. When the patient leaves the weighing plate 3 after the weight measurement is completed, the top of the weighing sensor 4 loses pressure, and a secondary start signal is output to the external controller. At this time, the external controller starts the driving motor 7, and the driving motor 7 drives the winding roller 8 to rotate to wind up the isolation film 9, and the isolation film 9 that the patient has stepped on and touched is rolled up to achieve the effect of recycling, and a new isolation film 9 is covered on the top of the weighing plate 3, which can effectively avoid bacterial cross infection and improve the protection effect. After the patient's weight measurement is completed, the wrist can be pressed down to the top of the near-infrared vein detector 12, and the patient's blood sugar and blood oxygen can be detected by the near-infrared vein detector 12. At the same time, the photoelectric sensor finger cuff 13 can be worn to monitor the ratio of oxygenated hemoglobin and deoxygenated hemoglobin in the blood in real time, and the ratio of body fat and muscle can be estimated through the body fat meter 14, so as to facilitate the preliminary record of the patient's physical condition.
