Description

Technical Field

[0001] This utility model relates to the field of physiological sensor technology, specifically a physiological sensor for a contact detection device. Background Technology

[0002] In recent years, with the development of electronic technology, computer technology, digital signal processing technology, and automation, the acquisition of human physiological signals has shifted from mechanization to electronicization. This has facilitated research on the physiological and pathological conditions of life, resulting in a greater diversity of acquired signals and more accurate and reliable results, which is of great significance in clinical diagnosis, medical treatment, and medical teaching and research. Human physiological signals are diverse. From an electrical perspective, they can be divided into electrical signals and non-electrical signals. Electrical signals include electrocardiograms (ECG), electromyograms (EMG), and electroencephalograms (EEG), while non-electrical signals include respiration, invasive and non-invasive blood pressure, blood oxygen saturation, end-tidal carbon dioxide, body temperature, cardiac output, and pulse. Because the human body is a complex organism, various signals are affected by many factors, including the body itself and the external environment. Therefore, to ensure the accuracy of the measured signals, appropriate physiological signal acquisition equipment is needed. While existing patch-type physiological sensors can be directly attached to the skin surface for detection, prolonged use and sweating can easily cause these sensors to fall off, affecting the detection results.

[0003] Therefore, this utility model provides a physiological sensor for a contact detection device. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a physiological sensor for a contact detection device, thereby solving the problems mentioned in the background section. This invention, by installing a slider on one side of the outer shell and a compression fixing structure on the slider, allows the device to be mounted on a strap or watchband, ensuring contact between the patch-type physiological sensor and the skin and preventing it from falling off during use. A positioning structure is installed between the outer shell and the slider for easy disassembly and installation. A heating resistor is installed between the two sliders to heat localized areas of the body, stimulating sweating and allowing the patch-type physiological sensor to detect physiological activity through sweat.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a physiological sensor for a contact detection device, including a housing, a display screen, two sliders slidingly fitted on one side of the housing, a pressing and fixing structure mounted on the sliders, a positioning structure between the housing and the sliders, a patch-type physiological sensor body fixed on one side of the sliders, a heating resistor sheet mounted between the two sliders, and a locking block mounted on both sides of the heating resistor sheet, with the locking block corresponding to the slider.

[0006] Furthermore, the patch-type physiological sensor body is connected to the display screen via wires, and a strap is installed on one side of the housing, which corresponds to the slider.

[0007] Furthermore, a groove is provided on one side of the outer shell, and the groove corresponds to the slider, which has an L-shaped structure.

[0008] Furthermore, the positioning structure includes an iron sheet fixed in the groove and an electromagnet fixed on the slider, with the electromagnet connected to the display screen via wires.

[0009] Furthermore, multiple springs are fixed between the groove and the slider, and the compression fixing structure includes a friction block fixed to one end of the slider.

[0010] Furthermore, the slider has a slot that corresponds to the block.

[0011] Furthermore, a first electrode plate is fixed in the slot, and a second electrode plate is fixed on the card block. The first electrode plate corresponds to the second electrode plate, and the first electrode plate is connected to the display screen through a wire.

[0012] Furthermore, a connecting wire is installed between the heating resistor sheet and the card block, and the connecting wire is connected to the second electrode sheet.

[0013] The beneficial effects of this utility model are as follows: This utility model provides a physiological sensor for a contact detection device, comprising a housing; a slider; a compression fixing structure; a strap; a patch-type physiological sensor body; a positioning structure; and a heating resistor sheet.

[0014] A slider is installed on one side of the outer shell, and a compression fixing structure is installed on the slider to install the device on a strap or watch strap. This ensures that the patch-type physiological sensor body is in contact with the skin and prevents the patch-type physiological sensor body from falling off during use. A positioning structure is installed between the outer shell and the slider to facilitate the disassembly and installation of the device. A heating resistor is installed between the two sliders to heat local parts of the body, thereby stimulating the body to sweat, so that the patch-type physiological sensor body can detect human physiological functions through sweat.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a physiological sensor for a contact detection device, including a housing 2, a display screen 1 mounted on the housing 2, two sliders 5 slidingly fitted on one side of the housing 2, a compression fixing structure mounted on the sliders 5, a positioning structure mounted between the housing 2 and the sliders 5, a patch-type physiological sensor body 8 fixed on one side of the sliders 5, a heating resistor 17 mounted between the two sliders 5, and a locking block 12 mounted on both sides of the heating resistor 17, the locking block 12 corresponding to the slider 5.

[0022] In this embodiment, the patch-type physiological sensor body 8 is connected to the display screen 1 by wires, and a strap 10 is installed on one side of the housing 2, which corresponds to the slider 5.

[0023] The results detected by the patch-type physiological sensor body 8 can be displayed on the screen 1, so that one can know one's physical condition at any time.

[0024] The device can be clipped onto the watch strap using slider 5, so that the patch-type physiological sensor body 8 is attached to the inner side of the wrist, or the device can be clipped onto the strap 10, so that it can be attached to other parts of the body, thereby facilitating the detection of the body's physiological condition.

[0025] A groove 3 is provided on one side of the outer casing 2. The groove 3 corresponds to the slider 5. The slider 5 has an L-shaped structure. The positioning structure includes an iron plate 4 fixed in the groove 3 and an electromagnet 7 fixed on the slider 5. The electromagnet 7 is connected to the display screen 1 through a wire. Multiple springs 6 are fixed between the groove 3 and the slider 5. The compression fixing structure includes a friction block 9 fixed to one end of the slider 5.

[0026] Specifically, when the device needs to be installed on the strap 10, the slider 5 can be pulled, and the strap 10 can be placed between the two sliders 5. Then, the sliders 5 can be released, causing them to move closer together under the action of the spring 6, thereby clamping the strap 10. Alternatively, the electromagnet 7 can be activated, causing it to attract and fix itself to the iron plate 4, thus securing the slider 5. Similarly, the device can be installed on the watch strap.

[0027] The slider 5 has a slot 11, which corresponds to the block 12. A first electrode plate 13 is fixed in the slot 11, and a second electrode plate 14 is fixed on the block 12. The first electrode plate 13 and the second electrode plate 14 correspond to each other. The first electrode plate 13 is connected to the display screen 1 through a wire. A connecting wire 18 is installed between the heating resistor 17 and the block 12, and the connecting wire 18 is connected to the second electrode plate 14.

[0028] Specifically, when the patch-type physiological sensor body 8 is attached, the card block 12 can be inserted into the card slot 11 separately, so that the first electrode plate 13 and the second electrode plate 14 are energized, thereby energizing the heating resistor plate 17, which will cause the heating resistor plate 17 to heat up, thereby stimulating local sweating of the human body, and the sweat can be detected by the patch-type physiological sensor body 8.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
