Description

Technical Field

[0001] This invention relates to the field of medical protective equipment technology, specifically to a pressure-applying ice-cooling glove. Background Technology

[0002] Chemotherapy is a core clinical treatment for malignant tumors. Paclitaxel, UTD, and other chemotherapeutic drugs are widely used in the clinical treatment of various malignant tumors, including breast cancer, lung cancer, and ovarian cancer, due to their broad antitumor spectrum and definite efficacy. However, these drugs have significant peripheral neurotoxicity, causing chemotherapy-induced peripheral neuropathy. Clinical symptoms mainly include numbness, tingling, paresthesia, and limited movement in the hands. In severe cases, it can lead to chemotherapy interruption and a significant decline in quality of life, becoming a key adverse reaction restricting the clinical application of these drugs.

[0003] Current clinical prevention of this type of peripheral neuropathy mainly employs a double-layer protective approach using a smaller-sized sterile rubber glove and an ice glove. This approach relies on passive compression from the rubber glove and physical icing from the ice glove to attempt to reduce drug damage to peripheral nerves. However, in practical application, it suffers from several unresolved technical limitations: First, the procedure is cumbersome and has poor clinical suitability. Wearing double gloves requires putting on rubber gloves and ice gloves in sequence, which is complicated and time-consuming, increasing the workload of medical staff and failing to meet the preparation needs of rapid clinical chemotherapy. The multiple layers of gloves severely restrict hand movement, affecting basic operations such as chemotherapy infusion and limb movement, resulting in extremely low patient compliance.

[0004] Second, the pressure is not adjustable and there is insufficient individual adaptability. Traditional methods rely on the elasticity of a smaller rubber glove to achieve passive pressure. The pressure is fixed and cannot be adjusted. It cannot adapt to the physiological characteristics of patients of different ages, hand shapes, and wrist circumferences, nor can it adjust the pressure according to the patient's tolerance. It is easy to cause insufficient pressure, resulting in prevention failure, or excessive pressure, which hinders blood circulation in the hand and causes swelling and discomfort in the limb.

[0005] Third, the temperature control is imprecise and the safety of use is low; traditional ice gloves do not have a dedicated temperature control structure and temperature monitoring device, and the temperature of the cold source fluctuates greatly. This can easily lead to frostbite or allergic irritation due to excessively low temperatures, or situations where the temperature is too high to reach the effective prevention range. Neither the protective effect nor the safety of use can be guaranteed.

[0006] To address the aforementioned shortcomings of existing technologies, this invention provides a pressurized ice-applying glove that integrates pressurization, ice application, precise temperature control, and adjustable pressure functions. Summary of the Invention

[0007] In order to overcome the shortcomings of the prior art, the present invention provides a pressure-cooling glove that can actively prevent peripheral neuropathy caused by chemotherapy drugs, thereby improving the protective effect and the patient's experience.

[0008] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A pressure-cooling glove includes a glove body comprising an outer glove layer and an inner glove layer. A medical cold source chamber is installed in the interlayer between the outer and inner glove layers. A display screen and a temperature sensor are installed on the wrist of the glove body. An annular elastic pressure band is provided on the outer glove layer and is embedded in the palm, back of hand, and wrist. A mechanical adjustment knob is provided on the wrist of the glove body, and the mechanical adjustment knob and the annular elastic pressure band are connected by a transmission mechanism.

[0009] Preferably, a 2mm thick heat insulation buffer layer is provided in the interlayer between the outer and inner layers of the glove, and the heat insulation buffer layer is located between the medical cold source compartment and the inner layer of the glove.

[0010] Preferably, the transmission mechanism includes a cylinder fixedly installed on the wrist of the glove body, and a winding shaft is rotatably installed inside the cylinder, with one end of the winding shaft fixedly connected to a mechanical adjustment knob.

[0011] Preferably, both ends of the annular elastic pressure belt are fixedly connected to the winding shaft, and slots are provided on both sides of the cylinder for the annular elastic pressure belt to pass through.

[0012] Preferably, the inner layer of the glove is made of medical-grade soft cotton material, the outer layer of the glove is made of heat-insulating material, the main body of the glove is designed with separate fingers, the wrist is a stretchable elastic structure, and the fingertips are provided with ventilation holes.

[0013] Preferably, the medical cold source compartment is a sealed structure, filled with temperature-controlled gel, with a temperature control range of 2-8℃. The medical cold source compartment can be removed independently and frozen at -20℃ for 2 hours before use.

[0014] Preferably, the temperature sensor monitors the temperature of the medical cold source chamber in real time, and the temperature display screen has a temperature display accuracy of ±0.5℃.

[0015] Preferably, the pressure adjustment range of the annular elastic pressure belt is 0.02-0.05 MPa, and the mechanical adjustment knob is marked with scales, with each scale corresponding to a pressure adjustment value of 0.005 MPa.

[0016] The beneficial effects of this invention are as follows: 1. This invention integrates pressurization, ice application, temperature control, and monitoring functions into a single glove, eliminating the need for multiple layers and allowing for complete protective preparation with a single wear. This significantly shortens the preparation time before chemotherapy, meets the needs of rapid clinical operations, and the integrated structure facilitates cleaning, storage, and reuse, reducing clinical usage costs.

[0017] 2. By setting up a mechanical knob and transmission mechanism, the pressure can be precisely adjusted within the range of 0.02-0.05MPa, so that it can be personalized according to the patient's hand shape and tolerance, replacing the traditional passive pressure method, avoiding insufficient pressure or excessive tightness and discomfort, and suitable for patients of all ages and multiple hand shapes.

[0018] 3. By maintaining the medical cold source chamber at an effective preventive temperature of 2-8℃, and with the help of high-precision sensors and displays, the temperature is monitored in real time to prevent frostbite or ineffective temperature measurement; the 2mm heat insulation buffer layer disperses the cold energy and avoids local low temperature stimulation, greatly improving the safety of use.

[0023] The following will refer to the attached reference. Figures 1 to 3 The various embodiments of the present invention will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0024] A pressure-cooling glove includes a glove body 1, which comprises an outer glove layer 101 and an inner glove layer 102, which are sewn together to form a sealed interlayer. The inner glove layer 102 is made of medical-grade soft and skin-friendly non-woven fabric, which is non-irritating and non-allergenic when in direct contact with the skin and is suitable for long-term wear. The outer glove layer 101 is made of medical heat-insulating fabric to reduce the loss of cold source temperature and prolong the effective duration of ice application. The glove body 1 adopts a finger-separated design to retain the freedom of finger movement and does not affect actions such as infusion and gripping during chemotherapy. The wrist has a highly elastic and stretchable structure to adapt to patients with different wrist circumferences and improve the fit. Circular ventilation holes are reserved at the fingertips to dissipate the heat and moisture inside the fabric in time, avoiding problems such as stuffiness, itching and sweating during long-term wear, and further optimizing the wearing experience.

[0025] A 2mm thick heat-insulating buffer layer 103 is provided in the interlayer between the outer layer 101 and the inner layer 102 of the glove. The heat-insulating buffer layer 103 is made of flexible medical sponge material and is located between the medical cold source chamber 104 and the inner layer 102 of the glove. Its core function is to evenly distribute the cold energy of the medical cold source chamber 104, avoid local low temperature from directly contacting the skin and causing frostbite, and at the same time buffer the pressure brought by the pressure, thereby improving the wearing comfort.

[0026] The interlayer also houses a sealed medical cold source compartment 104, which is a detachable and independent structure filled with medical temperature-controlling gel. This gel has been tested and can stably maintain a clinically effective preventive temperature of 2-8℃. Before use, the cold source compartment can be removed separately and placed in a -20℃ medical refrigerator for 2 hours. After the cold storage is completed, it can be put back into the interlayer for use. The operation is simple and the cold energy is long-lasting.

[0027] The wrist of the glove body 1 is equipped with a display screen 105 and a temperature sensor 106. The probe end of the temperature sensor 106 is in close contact with the outer wall of the medical cold source chamber 104 to collect the internal temperature data of the cold source chamber in real time. The display screen 105 and the temperature sensor 106 are electrically connected through built-in wires. The temperature display accuracy can reach ±0.5℃. Medical staff and patients can intuitively view the real-time temperature. If the temperature exceeds the range of 2-8℃, the cold source chamber can be replaced in time to ensure the ice pack effect and safety of use.

[0028] An annular elastic pressure band 2 is provided on the outer layer 101 of the glove, and a mechanical adjustment knob 3 is provided on the wrist of the glove body 1. The annular elastic pressure band 2 is made of high-elasticity medical silicone material and is evenly embedded in the palm, back of hand and wrist of the outer layer 101 of the glove, completely conforming to the contour of the hand to achieve all-round uniform pressure. The transmission mechanism includes a cylinder 4 fixed to the wrist of the glove body 1 and a winding shaft 6 rotatably installed in the cylinder 4. One end of the winding shaft 6 is fixedly connected to the mechanical adjustment knob 3. Both ends of the annular elastic pressure band 2 pass through the slots 5 on both sides of the cylinder 4 and are fixed on the winding shaft 6. The slots 5 play a limiting and guiding role for the pressure band to avoid deviation and wrinkles during winding. There is a constant rotational friction between the winding shaft 6 and the cylinder 4. When the knob is rotated without external force, the mechanical adjustment knob 3 remains in a fixed position, and the contraction state of the annular elastic pressure band 2 is locked to maintain stable pressure without the need for continuous manual adjustment.

[0029] The pressure adjustment range of the ring-shaped elastic pressure band 2 is 0.02-0.05MPa. The mechanical adjustment knob 3 has clear scale markings on its surface, with each scale corresponding to a pressure adjustment value of 0.005MPa. Patients can rotate the knob to precisely adjust to a comfortable pressure according to their own hand size and tolerance. The clinically recommended pressure is 0.03MPa, which can meet the physiological needs of most patients.

[0030] Working principle In the initial state, the mechanical adjustment knob 3 is in the initial position, the winding shaft 6 has not wound up the annular elastic pressure band 2, the pressure band is in a naturally stretched state, and the glove body 1 can be easily worn on the patient's hand.

[0031] Pressurization operation: Rotate the mechanical adjustment knob 3 in the forward direction. The knob drives the winding shaft 6 to rotate synchronously inside the cylinder 4. The winding shaft 6 winds up the annular elastic pressure belt 2, causing the pressure belt to contract circumferentially along the hand, generating uniform radial pressure on the palm, back of the hand, and wrist. The pressure changes synchronously with the rotation angle of the knob, and the knob scale can accurately correspond to the pressure value.

[0032] Pressure Locking: After adjusting to the target pressure, the friction between the winding shaft 6 and the cylinder 4 locks the knob position, and the contraction state of the annular elastic pressure belt 2 remains unchanged, continuously and stably outputting pressure.

[0033] Pressure reduction operation: Rotate the mechanical adjustment knob 3 in the opposite direction to release the annular elastic pressure belt 2 from the winding shaft 6. The pressure belt gradually expands, and the radial pressure decreases synchronously until it returns to the initial state, thus completing the pressure reduction.

[0034] Ice pack temperature control principle: The temperature-controlling gel inside the medical cold source chamber 104 stores a large amount of cold energy after freezing. After being placed in the glove interlayer, the low temperature is evenly released to the hand through the heat insulation buffer layer 103, stably maintaining an effective preventive temperature of 2-8℃. The temperature sensor 106 collects the temperature of the cold source chamber in real time and transmits it to the display screen 105 to realize the visual monitoring of the temperature. The heat insulation buffer layer 103 disperses the cold energy and avoids the local low temperature from directly stimulating the skin, thus structurally eliminating the risk of frostbite and ensuring the safety of ice pack application.

[0035] Synergistic prevention principle: Compression and ice application form a dual protective synergistic effect. Compression can constrict peripheral blood vessels in the hand, reducing the concentration of chemotherapy drugs in the peripheral nerves of the hand, and directly reducing the toxic damage of drugs to nerves. Ice application can reduce the metabolic activity and pain sensitivity of nerve endings in the hand, and alleviate the numbness, tingling and other irritation symptoms caused by drugs. The combination of the two achieves proactive early intervention, transforming traditional passive care into active protection, and fundamentally reducing the incidence and severity of peripheral neuropathy caused by chemotherapy drugs such as paclitaxel and UTD.

[0036] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
