Abstract
Description
Technical Field

[0002] In the medical field, medical gloves are important protective equipment for medical staff in their daily work. Their main function is to prevent cross-infection and protect the safety of medical staff's hands.
[0003] However, traditional medical gloves usually adopt a fixed-size design at the wrist, which is difficult to adapt to the differences in wrist thickness among different users, and can easily cause the gloves to be too loose or too tight. Gloves that are too loose may slip during operation, affecting work efficiency and increasing the risk of infection; while gloves that are too tight may cause blood circulation in the hands to be blocked, causing discomfort or even fatigue.
[0004] Furthermore, the palms and fingers of gloves often lack the dynamic adaptability to bending movements. When medical personnel perform delicate operations, the inadequate fit of the gloves to the hands can lead to operational inconvenience and even affect the accuracy of surgery or treatment. Existing solutions attempt to improve glove fit by adding elastic materials or adjusting structural designs, but these solutions often lack real-time pressure regulation and dynamic deformation sensing, making them difficult to meet the stringent requirements of complex medical environments. Summary of the Invention
[0005] Through research, the inventors discovered that a medical glove wrist clamp device that can adjust pressure in real time according to the thickness of the user's wrist and has the ability to dynamically sense finger bending and deformation will become an important research direction in the current field of medical protective equipment.
[0006] The purpose of the present invention is to provide a modular medical glove wrist clip based on 3D printing. By setting a sensing unit and an adjustment device inside the glove and combining it with a flexible connection structure, precise fit and real-time pressure adjustment of the palm and wrist are achieved, thereby solving the technical problem of poor comfort caused by insufficient fit or uneven pressure distribution on the wrist and palm during wearing of medical gloves.
[0007] The present invention provides a combined medical glove wrist clip based on 3D printing, comprising a 3D-printed wrist and a palm connected to the wrist via a flexible connector, wherein a tension sensing unit and a pressure regulator are provided on the inner side of the wrist; the palm comprises at least a first finger joint deformation sensor, a second finger joint deformation sensor, a third finger joint deformation sensor, a fourth finger joint deformation sensor, and a fifth finger joint deformation sensor, between the wrist and the palm.

[0023] EMBODIMENT
[0024] The specific implementation of the printing type combined medical glove wrist clamp provided by the present application is described in detail in combination with the accompanying drawings and the specific implementation of the printing type combined medical glove wrist clamp provided by the present application. Figure 1 and the specific implementation of the printing type combined medical glove wrist clamp provided by the present application. Figure 2 are described in detail.
[0025] Figure 1 This is a schematic diagram of the overall appearance, showing the design features of the glove's wrist and palm. Figure 2 A schematic diagram of the wrist clamp structure of the present invention is shown, wherein the wrist 1 and the palm 2 are physically connected through a flexible connector, and the wrist 1 includes at least a tension sensing unit 3 and a pressure regulator 4, and the palm 2 includes a first finger joint deformation sensor 5, a second finger joint deformation sensor 6, a third finger joint deformation sensor 7, a fourth finger joint deformation sensor 8 and a fifth finger joint deformation sensor 9.
[0026] Specifically, the tension sensing unit 3 of the wrist 1 is composed of a plurality of piezoresistive sensor arrays, and the sensitive area of each sensor is designed to be 4mm 2 Up to 6mm 2 The aforementioned sensors are connected in series via a flexible circuit board to form a mesh structure, covering the primary stress-bearing area on the inside of the wrist. When a healthcare worker puts on the glove and their palm enters the glove, the tension sensor unit 3 on wrist 1 generates a deformation signal based on changes in wrist thickness. This signal is converted into an electrical signal and transmitted to the pressure regulator 4. The pressure regulator 4 employs a modular design and comprises a signal processing unit, an execution unit, and a power supply module. The signal processing unit filters and amplifies the received electrical signal and then calculates the appropriate pressure value based on a preset algorithm. Based on the calculated result, the execution unit drives the built-in micro-airbags or elastic material layer to expand or contract, adjusting the pressure distribution between the wrist and the glove. For thinner wrists, the pressure regulator 4 reduces the airbag inflation volume to reduce wrist pressure; conversely, it increases the airbag inflation volume to increase pressure. This dynamic pressure regulation mechanism ensures a tight fit without excessively compressing the skin tissue.
[0027] The five knuckle deformation sensors on the palm 2 correspond to the five finger joints of the human hand, and the sensitive area is designed to be 3mm 2 Up to 5mm 2 . Each finger joint deformation sensor adopts piezoresistive sensor technology and is equipped with an independent signal conditioning circuit to eliminate external interference and perform preliminary processing on the original signal. When the medical staff bends or stretches their fingers, each finger joint deformation sensor will sense the deformation of the finger joint and convert the deformation signal into an electrical signal, which is then transmitted to the pressure regulator 4. The pressure regulator 4 dynamically adjusts the pressure distribution in different areas of the palm according to the received signal. When the thumb is bent, the first finger joint deformation sensor 5 will generate a corresponding deformation signal. After receiving the signal, the pressure regulator 4 drives the elastic material layer in the corresponding area of the palm to make fine adjustments, thereby achieving precise fit between the gloves and the fingers. This design not only improves the comfort of wearing the gloves, but also can adapt to different hand shapes and finger activity requirements.
[0028] The wrist 1 and palm 2 are physically connected via a flexible connector made of a polymer elastic material with a thickness ranging from 0.5mm to 1.2mm, exhibiting excellent ductility and resilience. The two ends of the flexible connector are fixed to the edges of the wrist 1 and palm 2, respectively. Embedded wires electrically connect the tension sensor unit 3 on the wrist 1 and the knuckle deformation sensor on the palm 2 to the pressure regulator 4. In practice, the design of the flexible connector ensures a stable and flexible connection between the wrist 1 and palm 2, effectively preventing loosening or breakage due to hand movement.
[0029] In order to better illustrate and understand the present invention, the working principle of the present invention is as follows:
[0030] First, when a medical worker puts on a glove, the palm of the hand enters the glove. The tension sensor unit 3 on the wrist 1 senses the change in wrist thickness and transmits the deformation signal to the pressure regulator 4.
[0031] Next, the pressure regulator 4 analyzes the received signal and adjusts the pressure distribution on the wrist by driving the built-in airbag or elastic material layer;
[0032] Furthermore, during the finger movement, the five finger joint deformation sensors of the palm 2 sense the finger joint deformation and transmit the signal to the pressure regulator 4;
[0033] Next, the pressure regulator 4 dynamically adjusts the pressure distribution in different areas of the palm according to the received signal to ensure that the fit between the glove and the fingers is appropriate;
[0034] Finally, the whole process continues to adapt to different hand sizes and finger movement requirements.
[0035] It should be noted that to enhance the overall suitability and flexibility of the glove, all components are constructed from lightweight materials. Both the tension sensor unit 3 and the knuckle deformation sensor utilize flexible printed circuit boards as their substrates, ensuring accurate signal acquisition while accommodating the limited internal space of the glove. The elastic material layer of the pressure regulator 4 is made of silicone, offering excellent flexibility and durability, ensuring stable performance even after repeated use.
[0036] To facilitate large-scale production and practical application, all components of the present invention are designed as a modular structure, allowing for direct integration into existing medical glove production processes. The tension sensor unit 3 and the knuckle deformation sensor can be fixed to the inside of the glove via a heat-pressing process, while the pressure regulator 4 can be attached to the outside of the glove via snaps or adhesive.
[0037] The practical application scenarios of the present invention include but are not limited to operating rooms, laboratories and other occasions where medical gloves need to be worn.
[0038] During surgery, medical staff's hands move frequently and delicately. Traditional medical gloves often suffer from poor comfort and low stability due to insufficient fit or uneven pressure distribution. The present invention provides multiple sensing units and adjustment devices on the wrist 1 and palm 2, combined with a flexible connection structure, to achieve precise fit between the glove and the hand and real-time pressure adjustment. During long surgeries, medical staff's hands are prone to fatigue, and the pressure regulator 4 of the present invention can automatically adjust the pressure distribution according to the hand's movements, significantly reducing the burden on the hands. In addition, during laboratory operations, medical staff may need to change gloves frequently. The dynamic pressure adjustment mechanism of the present invention can quickly adapt to different hand shapes, reducing the time cost of changing gloves.
[0039] In summary, the present invention incorporates sensing units and adjustment devices on the wrist 1 and palm 2, combined with a flexible connection structure, to provide a novel and functionally complete printed modular medical glove wrist clip. The tension sensing unit 3 on the wrist 1 and the knuckle deformation sensor on the palm 2 work in tandem, enabling dynamic pressure regulation via the pressure regulator 4. This significantly improves the glove-wearing experience for medical personnel, enhancing not only the comfort and stability of the gloves but also their applicability and flexibility.
