Description

Technical Field

[0001] This utility model belongs to the field of human skin impedance acquisition or measurement technology, and in particular relates to a vertical hand mold for a meridian impedance acquisition device. Background Technology

[0002] Meridian impedance testing is a technique that assesses health status by measuring the electrical properties of acupoints on the human body. In this type of device, the user typically holds a hand model (hand mold), on which integrated electrodes contact specific acupoints to collect impedance signals. Therefore, the structural design of the hand mold directly affects the accuracy and repeatability of the measurement data.

[0003] Currently, existing meridian impedance acquisition hand molds mainly have the following defects: First, the repeatability of grip posture is poor. Traditional hand molds are mostly simple cylindrical or spherical structures, lacking effective grip guidance and positioning structures. Each time a user grips the mold, the position, angle, and contact point of the palm with the electrode pads may differ. This random error introduced by inconsistent grip postures causes repeated measurements to be inconsistent, seriously affecting the reliability and comparability of the test results.

[0004] Secondly, insufficient grip stability can easily lead to poor contact. Many existing hand molds have relatively smooth and rounded surfaces, and when held, the palm can easily slide relative to the mold surface due to gravity or slight movements. This sliding can cause unstable contact pressure between the electrode pads and acupoints on the skin, changes in contact area, or even momentary disconnection, resulting in fluctuations, distortion, or inaccuracy in the collected meridian impedance signals, which cannot truly reflect the physiological state of the human body.

[0005] For example, Chinese patent document CN 215937353 U discloses a meridian impedance acquisition device. Although it improves the comprehensiveness of information acquisition by setting multiple electrode plates and loop electrodes, its detection hand mold still lacks the necessary limiting and anti-slip structure, and fails to fundamentally solve the problem of measurement consistency and accuracy caused by human grip factors.

[0006] Therefore, there is an urgent need in this field for a novel hand mold structure that can effectively guide and fix the grip posture, ensure that the height of the hand in contact with the electrode is consistent during each measurement, and prevent accidental slippage during the measurement process, thereby comprehensively improving the accuracy and repeatability of meridian impedance acquisition data.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0020] Please refer to Figures 1 to 5 A vertical hand mold for a meridian impedance acquisition device includes a hollow hand mold shell 1. The hand mold shell 1 has a palm root support part 11 at the bottom, a collection area 12 in the middle, and a grip posture guide part 13 at the top. The hand mold shell 1 has an overall conical structure that is smaller at the top and larger at the bottom. The collection area 12 includes a thumb collection area 14, collection areas for the other four fingers 15, and a tiger's mouth collection area 151. The intersection of the thumb collection area 14 and the other four finger collection areas 15 is the tiger's mouth collection area, which is provided with a tiger's mouth positioning part 16. The four finger collection areas 15 are provided with interfinal isolation parts 17 to separate adjacent fingers. The thumb collection area 14, the other four finger collection areas 15, and the tiger's mouth collection area are respectively provided with electrode plate mounting grooves 18 along the direction of each finger for mounting electrode plates. A bottom cover 19 is detachably installed at the bottom of the hand mold shell 1.

[0021] This design, through its overall conical structure and partitioned design, effectively guides users to hold the device in a side-grip manner. Combined with the tiger's mouth positioning section and the interfinal isolation section, it significantly improves positioning accuracy and stability during repeated gripping, preventing poor electrode contact caused by hand slippage. The palm heel support provides reliable support, reducing hand tremors during prolonged measurements and ensuring close contact between the electrode pads and acupoints, thereby significantly improving the accuracy and repeatability of meridian impedance data. The removable bottom cover facilitates internal maintenance and electrode replacement, enhancing the product's practicality and lifespan.

[0022] Further preferably, the grip posture guide 13 includes a tapered guide structure, suitable for guiding the palm to grip along a preset direction, thereby limiting the palm position and improving positioning accuracy during repeated gripping. This solution, by limiting the grip path and direction through the tapered guide structure, ensures that the user's palm position is consistent each time they grip, effectively solving the problem of poor repeated positioning accuracy caused by the lack of a restrictive structure in the old model. This structure effectively avoids changes in electrode contact points caused by grip posture deviations, significantly improving the consistency of multiple measurement data and providing a reliable basis for meridian impedance detection.

[0023] Further preferably, the tiger's mouth positioning part 16 is a protrusion adapted to the shape of the human tiger's mouth, used to restrict the position of the tiger's mouth when gripping, and enhance the stability of hand posture. This solution, through the ergonomically designed protruding tiger's mouth positioning part, allows the user's tiger's mouth to naturally lock in place when gripping, effectively restricting lateral movement of the hand and enhancing overall grip stability. This design avoids the palm slippage caused by the smooth surface of the old model, ensuring that the electrode plate maintains constant contact pressure with the finger acupoints, thereby improving the quality and accuracy of impedance signal acquisition.

[0024] Further preferably, the interdigital isolator 17 is a protruding structure extending along the finger direction, its height and shape suitable for guiding the fingers to be placed separately, and ensuring that each finger corresponds to the corresponding electrode mounting slot 18. This solution achieves natural finger separation through the protruding structure of the interdigital isolator, avoiding interference or overlap between adjacent fingers, and ensuring that each finger is accurately aligned with the corresponding electrode mounting slot. This design improves the alignment accuracy between the electrode and the acupoint, effectively prevents signal acquisition errors caused by finger position deviation, and enhances grip comfort and stability, making it suitable for users with different hand shapes.

[0025] More preferably, the palm heel support 11 is an arc-shaped structure that matches the shape of the palm heel. This design provides uniform support to the user's palm heel through the arc-shaped palm heel support, effectively distributing hand pressure and reducing fatigue and shaking caused by prolonged gripping. This design ensures that the palm fits tightly against the model during measurement, avoiding changes in electrode contact caused by slight hand movements, thereby ensuring the continuity and accuracy of the collected data.

[0026] Preferably, the bottom cover 19 is fixedly connected to the bottom of the hand mold housing 1 via a snap-fit, threaded, or bolted connection. This solution achieves reliable fixation between the bottom cover and the housing through multiple detachable connection methods, facilitating quick opening for internal cleaning, electrode replacement, or circuit maintenance, greatly improving the product's maintainability and service life. The modular design reduces maintenance costs while ensuring the overall sealing and structural strength of the housing.

[0027] More preferably, the electrode mounting slot 18 has an elongated structure. This design, by creating an elongated structure for the electrode mounting slot, provides a longer contact range in the finger direction. This design can accommodate differences in finger length and acupoint location among users. When the user holds the device, the electrode can effectively contact the acupoints within the area covered by the elongated slot, solving the problem of poor electrode contact or signal loss caused by varying hand sizes, and significantly improving the device's versatility and measurement success rate.

[0028] Further preferably, the length direction of the electrode mounting groove 18 on the thumb acquisition area 14 and the other four finger acquisition areas 15 is consistent with the finger gripping direction; the length direction of the electrode mounting groove 18 in the tiger's mouth positioning part 16 is perpendicular to and / or consistent with the tiger's mouth direction. This solution optimizes the direction of the electrode mounting groove in different functional areas to make it highly compatible with the human anatomical structure. The groove direction in the finger area follows the finger extension direction to ensure that the electrode is naturally aligned with the acupoint on the finger; the groove direction in the tiger's mouth area is designed according to the physiological direction of the tiger's mouth, either perpendicular or consistent, to ensure that the electrode in this key area has full and stable contact with the skin. This zoned orientation design maximizes the effective contact area of ​​the electrode, further improving the accuracy and stability of signal acquisition.

[0029] Working Principle Description: During use, the user holds the hand mold with a side grip, moving from the outside in. The base of the palm rests against the palm support 11, and the web of the hand engages with the web positioning part 16. Each finger is naturally placed between the interdigital isolation parts 17, ensuring a consistent grip posture each time. The electrode pads in the electrode mounting slots 18 contact specific acupoints on the fingers. The signal control unit generates a measurement signal, which forms a circuit through the electrode pads and human tissue to collect meridian impedance data. The tapered structure of the grip posture guide 13 further restricts the palm position, preventing slippage and ensuring the continuity and accuracy of signal acquisition during measurement. The overall design makes the measurement process stable and reliable, suitable for repetitive medical tests.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
