Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a multifunctional glove with adaptive electro-thermal synergistic intervention. Background Technology

[0002] With advancements in technology and increasing demands for health management, the function of gloves has expanded beyond traditional warmth and protection. Modern gloves need breakthroughs in warmth, comfort, versatility, and intelligence to meet the needs of various scenarios. However, existing glove technology still suffers from the following major shortcomings:

[0003] First, most gloves only have basic warmth or protection functions and cannot simultaneously meet the needs of warmth and health care. Second, the current level of intelligence of gloves is low, and they cannot interact with human physiological signals in real time, making it difficult to meet the needs of modern users for health monitoring and intelligent intervention. Third, the control methods of existing gloves are relatively simple. The gloves cannot dynamically adjust the output power of the heating element or the intensity of electrical stimulation based on micro-environmental information such as internal pressure, temperature and humidity, and cannot achieve coordinated control of multiple parameters. Fourth, existing gloves lack a feedback mechanism based on pressure, temperature and electrical stimulation intensity, and cannot achieve dynamic adjustment between changes in internal pressure and heating temperature and electrical stimulation intensity, making it difficult to meet the needs of use in complex environments. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a multifunctional glove with adaptive electro-thermal synergistic intervention that is reasonably designed, simple in structure, easy to wear, and combines adaptive temperature regulation and warmth retention with electrostimulation health care and therapeutic effects.

[0005] The technical solution adopted to achieve the purpose of this utility model is:

[0006] A multifunctional glove with adaptive electro-thermal synergistic intervention includes a glove body, a pressure sensing unit, a temperature and humidity sensing unit, an electrical stimulation unit, a heating unit, and a controller. The pressure sensing unit and the temperature and humidity sensing unit are connected to the controller to collect microenvironment information inside the glove. The controller is connected to the electrical stimulation unit and the heating element to control the start or stop of the electrical stimulation element and the heating element.

[0007] The glove body includes a back of hand layer and a palm layer, and adopts a combination of active and passive warmth. The palm layer adopts a passive warmth method and includes a 3-layer structure design, namely the inner glove layer, the glove filling layer and the glove outer layer. The back of hand layer adopts an active warmth method and includes a 5-layer structure design, namely the electrical stimulation layer, the inner glove layer, the glove functional layer, the glove filling layer and the glove outer layer.

[0008] The pressure sensing unit is a miniature pressure sensor, mainly distributed at the junction of the proximal interphalangeal joint (second finger joint) and the distal interphalangeal joint (third finger joint) on the back of the hand. It is used to monitor the bending, stretching, shearing and their combined forces on the glove during actual use, and transmit the real-time monitored force information to the data processing and control unit in the form of electrical signals.

[0009] The temperature and humidity sensing unit is a miniature temperature and humidity sensor, mainly distributed on the metacarpophalangeal joints (first joints of the fingers) on the back of the hand. It is used to collect temperature and humidity information inside the glove and transmit the real-time monitored temperature and humidity information to the data processing and control unit in the form of electrical signals.

[0010] The electrostimulation unit is a metal patch electrode with a diameter of 0.5cm. The back of the metal electrode is welded with an ultra-fine wire for current signal transmission. The metal electrode corresponds to the finger well points such as Shaoshang, Zhongchong, Shaochong, Shangyang, Guanchong and Shaoze.

[0011] The heating element is a carbon nanotube film or other carbon material, which is set at the fingers and the back of the hand. The heating area is planar, providing comprehensive and uniform heating from all directions.

[0012] The controller is divided into two parts: an upper shell and a lower shell. It includes a power switch, a touch screen, a portable electric-thermal control module, a centralized power supply, a power indicator light, and a Type-C charging port. The upper shell is equipped with a touch screen and a power switch, while the lower shell is equipped with a portable electric-thermal control module and a centralized power supply. A Type-C charging port is located at the connection between the upper and lower shells, supporting 5V charging and discharging.

[0013] The portable controller is mounted on the glove body and fixed to the wrist of the glove body by a metal snap fastener with a mortise and tenon structure. The metal snap fastener is divided into a female snap fastener and a male snap fastener. One end of the female snap fastener is welded with a wire harness, and the other end is connected to a metal button. The metal button has the functions of signal transmission and fixing the main monitor.

[0014] The portable electro-thermal control module is equipped with a wireless communication module, which can upload information such as pressure, temperature, humidity, heating, electrical stimulation, and power supply inside the glove to a mobile phone and cloud server terminal in real time. The cloud server terminal analyzes and processes the data and provides heating temperature settings and electrical stimulation adjustment prescriptions that meet the user's skin needs. The main control unit operates according to the control signals given by the terminal.

[0015] The lumped power management module has a core circuit of a multi-channel DC-DC converter, which has a small number of discrete components, high reliability, and is easy to maintain and debug.

[0016] The controller receives micro-environmental information such as internal pressure, temperature, and humidity of the glove, uses algorithms to perform multi-parameter collaborative analysis and temperature control, automatically adjusts the output power and electrical stimulation current of the heating element, and intelligently adjusts the working temperature and electrical stimulation intensity prescription of the internal heating element of the glove. It also incorporates a principle and model algorithm based on pressure sensing and electrothermal conversion, enabling feedback between changes in internal pressure of the glove, heating temperature, and electrical stimulation intensity.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This invention uses a pressure sensing unit to monitor in real time the bending, stretching, shearing, and combined forces exerted on the glove during actual use. Based on the force information and microenvironmental data obtained from the temperature and humidity sensing unit, the main control unit calculates and processes the skin pressure, glove space changes, and skin comfort temperature. By predicting the optimal temperature requirements of human skin, the main control unit autonomously adjusts the heating temperature and electrical stimulation intensity to meet the body's needs. Furthermore, based on tactile information obtained from the pressure sensing unit, the main control unit determines the hand pressure and adjusts the current applied to the user's epidermis accordingly, achieving precise electrical stimulation control.

[0019] 2. The controller of this invention uses a microcontroller as its core and incorporates a built-in wireless communication module, enabling data interaction with terminal devices. Users can send control signals via the terminal; the controller receives and parses the signals, then outputs heating temperature control signals and electrical stimulation control signals tailored to the needs of human skin. The control system executes heating and electrical stimulation adjustment operations based on the control signals, dynamically adjusting the internal temperature of the glove and the intensity of electrical stimulation to enhance the user experience.

[0020] 3. The controller of this invention incorporates a model algorithm based on pressure sensing and electrothermal conversion principles, enabling dynamic feedback adjustment between changes in internal glove pressure and heating temperature and electrical stimulation intensity. Compared to existing technologies, this invention, through an adaptive collaborative intervention adjustment program, can intelligently adjust the glove's working state, simplifying the operation process, reducing energy consumption, and minimizing unnecessary power consumption and energy waste. This feature not only enhances the glove's intelligence but also expands its applicable population, making it more suitable for various scenarios such as medical treatment, rehabilitation, and sports.

Detailed Implementation

[0027] The present invention will be further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0028] See Figure 1-4 A multifunctional glove with adaptive electro-thermal synergistic intervention includes: glove body 1, multiple pressure sensing units 2, multiple temperature and humidity sensing units 3, multiple electrical stimulation units 4, multiple heating units 5, and portable controller 6.

[0029] The glove body is divided into a back hand layer and a palm layer with the palm as the dividing line. The back hand layer includes an electrical stimulation unit layer 4, an inner glove layer 11, a functional glove layer, a filling layer 13, and an outer glove layer 13. The functional layer includes a pressure sensing unit 3, a temperature and humidity sensing unit 3, and a heating unit 5. The palm layer includes an inner glove layer 11, a filling layer 13, and an outer glove layer 13. The electrodes of the electrical stimulation unit are placed in the inner layer to facilitate direct contact with the epidermal layer of the skin, and the heating unit layer is placed in the middle layer to avoid direct contact with the patient's skin and cause burns.

[0030] During implementation, the device is first worn on the user's hand, and the functional devices are adjusted to a fixed position. Multiple pressure-sensitive elements 3 are adjusted to the junction of the proximal interphalangeal joint (second finger joint) and the distal interphalangeal joint (third finger joint) on the back of the hand. The temperature and humidity-sensitive element 3 is adjusted to the metacarpophalangeal joint (first finger joint) on the back of the hand. The electrical stimulation unit 4 is aligned with the acupoints on the fingers. The diameter of the circular electrodes of the electrical stimulation unit 4 is 0.5cm. The first electrical stimulation point 41 corresponds to the Shaoshang acupoint, the second electrical stimulation point 43 corresponds to the Shangyang acupoint, the third electrical stimulation point 43 corresponds to the Zhongchong acupoint, the fourth electrical stimulation point 44 corresponds to the Guanchong acupoint, the fifth electrical stimulation point 45 corresponds to the Shaochong acupoint, and the sixth electrical stimulation point 46 corresponds to the Shaoze acupoint. The heating units are adjusted to the fingers and the back of the hand respectively. Among the heating units 5, the first heating unit 51 is 3cm*3cm in size, the second heating unit 53 is 5cm*3cm in size, the third heating unit 53 is 7cm*3cm in size, the fourth heating unit 54 is 6cm*3cm in size, the fifth heating unit 55 is 4cm*3cm in size, and the sixth heating unit 56 is 5cm*5cm in size.

[0031] Working principle: During implementation, the pressure sensing unit collects information from the glove body 1. Based on the pressure information obtained by the pressure sensing unit 3, the main control unit calculates and processes the skin pressure situation in the glove-human-microenvironment, the amount of change in glove space, and the skin comfort temperature. Combined with the data obtained by the temperature and humidity sensing unit 3, the main control unit analyzes the data to predict the optimal skin temperature requirement and performs autonomous regulation.

[0032] Based on tactile information, the main control unit judges the pressure on the hand and adjusts the current applied to the user's epidermis to regulate the intensity of electrical stimulation. Through the coordinated intervention of electrical stimulation and heating, the temperature of the fingers is increased, acupoints are stimulated, and the microcirculation of blood in the hand is accelerated.

[0033] The portable controller 6 is mounted on the wrist of the glove body. The metal snap on the back of the controller aligns and secures with the snap on the wrist of the glove body. The controller 6 has a built-in electro-thermal co-intervention module connected via wires to the pressure sensing unit 3, temperature and humidity sensing unit 3, electrical stimulation unit 4, and heating unit 5. This module is used for pressure and temperature / humidity monitoring and electrical stimulation heating control of the glove body 1. Pressing and holding the power button 61 activates the controller 6; the display screen illuminates when the device is powered on. Operation is performed according to the display screen. The device can be charged via a Type-C charging port 65. When the battery is low, the power indicator light 64 flashes to remind the user to charge it promptly.

[0034] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” are used in the embodiments to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that, in addition to the orientations shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figures is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations. The device may be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0035] Moreover, relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.

[0036] The above description is only a preferred embodiment of the present utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
