Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a medical ice hand and foot cover. Background Technology

[0002] Hand-foot syndrome is a common skin toxicity symptom in patients receiving anthracycline or taxane chemotherapy. Also known as palmoplantar erythematous hypoesthesia, it typically occurs in the palms and soles, clinically manifesting as numbness, hypoesthesia, pain, swelling, or erythema in the toes. In severe cases, it can progress to ulcers and intense pain, making it impossible for patients to wear shoes, walk, or use their hands to pick up objects, significantly impacting their quality of life.

[0003] Studies have shown that wearing ice gloves and ice foot covers during chemotherapy can effectively reduce sweating, thereby reducing damage to nerve endings from chemotherapy drugs and alleviating patient pain. This therapy requires pre-freezing and preparing the ice caps, gloves, and foot covers. They are worn continuously for 30 minutes before chemotherapy begins, during chemotherapy, and 90 minutes after chemotherapy ends, and should be replaced promptly if they change temperature. Currently, they are frozen in a refrigerator at -20°C. After freezing, the temperature is extremely low, causing severe discomfort for patients, leading many to refuse to wear them.

[0004] Chinese patent CN222032826U discloses a constant-temperature medical ice glove, including an outer glove body. The outer glove body has a zipper extending along its edge, creating a fully open structure that can be opened from both sides. Adhesive plates are fixedly bonded to the inner walls of both sides of the outer glove body, with a latex glove body bonded to one side of the adhesive plate. Mounting frames are fixedly connected to the outer sides of both sides of the outer glove body. A heat sink is fixedly fitted to one end of the mounting frame, and a semiconductor cooling chip is attached to one end of the heat sink. A conductive sheet is attached to the side of the semiconductor cooling chip away from the heat sink. Both the semiconductor cooling chip and the conductive sheet are fixedly mounted within the mounting frame. The semiconductor cooling chip is electrically connected to one end of a connecting wire, and a controller is fixedly connected to the other end of the connecting wire. An elastic band is fixedly sewn to the open end of the outer glove body, and Velcro is fixedly connected to the outside of the elastic band.

[0005] The aforementioned patent achieves a slower temperature drop through the use of a semiconductor cooling chip, which can reduce patient discomfort. However, when a patient has a fever, they cannot use ice gloves to further cool their forehead and reduce their discomfort. Utility Model Content

[0006] To address the shortcomings of existing technologies, the purpose of this invention is to propose a medical ice hand and foot glove. By incorporating a layered pocket into which an ice pack is placed, the ice pack can be removed and used to cool the forehead of a feverish patient, thus accelerating fever reduction. Furthermore, the inclusion of a semiconductor cooling component enables the gradual reduction of the glove's temperature, minimizing patient discomfort and resolving the issue of patients refusing to wear ice gloves, which could lead to nerve damage from chemotherapy drugs.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A medical ice hand and foot glove includes a glove body, a semiconductor cooling component is installed on the back of the glove body, and the semiconductor cooling component is electrically connected to a controller; a padded pocket is installed on the front of the glove body; and an ice pack is installed inside the padded pocket.

[0009] The glove body includes an innermost soft layer, a cold conduction layer attached to the outer surface of the soft layer, an insulation layer attached to the side of the cold conduction layer away from the soft layer, and a rubber layer attached to the outer wall of the insulation layer; the interlayer pocket is opened at the cold conduction layer, and the groove formed on the front of the glove body by dividing the cold conduction layer into two layers is the interlayer pocket.

[0010] Preferably, the semiconductor cooling component includes an outer frame inserted into the back of the glove body, a semiconductor cooling chip installed inside the outer frame, the bottom surface of the semiconductor cooling chip being bonded to the cold conduction layer, a heat sink being fixedly bonded to the upper surface of the semiconductor cooling chip, a temperature sensor being installed at the bottom of the semiconductor cooling chip, and both the temperature sensor and the semiconductor cooling chip being electrically connected to the controller.

[0011] Preferably, the cold conductive layer is a filamentous metal cold conductive layer.

[0012] Preferably, the controller is a PID controller.

[0013] Preferably, a zipper is installed between the opening of the interlayer pocket and the glove body.

[0014] Preferably, the temperature sensor is a platinum resistance temperature sensor.

[0015] Preferably, the opening of the glove body is provided with an elastic opening.

[0016] Preferably, the material inside the ice pack is silicone or polymer gel.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) The design of the interlayered pocket of this utility model allows for the placement of an ice pack inside the interlayered pocket of the hand and foot sleeve while the patient is cooling down their hands and feet. After the zipper is closed, the cold conduction is accelerated. The ice pack is then cooled down through the cold conduction layer and taken out to cool down the forehead of the feverish patient, which has the effect of accelerating the patient's fever reduction.

[0019] (2) This utility model uses a semiconductor cooling component to control the semiconductor cooling chip 220 for cooling. During cooling, the side in contact with the cold conduction layer 120 is cooled and conducted to the inside of the hand and foot sleeves, achieving a cooling effect. The side connected to the heat sink 230 is heated, generating a higher temperature. The heat sink 230 dissipates heat from the heated side of the semiconductor cooling chip 220, achieving the cooling function. Furthermore, the temperature is detected by the temperature sensor 240 set at the bottom of the semiconductor cooling chip 220 and transmitted to the controller 300. The controller controls the current of the semiconductor cooling chip 220 based on the measured temperature to achieve gradual cooling and heat preservation, improve patient adaptability, reduce patient discomfort, and allow simultaneous use of the hands and feet. This can effectively reduce sweating of the hands and feet, thereby reducing the damage of chemotherapy drugs to nerve endings and alleviating patient pain. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Example

[0026] like Figures 1-3 As shown, a medical ice hand and foot glove includes a glove body 100, a semiconductor cooling component 200 is installed on the back of the glove body 100, and the semiconductor cooling component 200 is electrically connected to a controller 300; a double-layered pocket 400 is installed on the front of the glove body 100; and an ice pack is installed inside the double-layered pocket 400.

[0027] The glove body 100 includes an innermost soft layer 110, a cold conduction layer 120 is attached to the outer surface of the soft layer 110, an insulation layer 130 is attached to the side of the cold conduction layer 120 away from the soft layer 110, and a rubber layer 140 is attached to the outer wall of the insulation layer 130; the interlayer pocket 400 is opened at the cold conduction layer 120, and the interlayer pocket 400 is a groove formed on the front of the glove body 100 by dividing the cold conduction layer 120 into two layers.

[0028] The soft layer 110 comes into direct contact with the patient's hands and feet, making it more comfortable for the patient to wear. The cold conduction layer 120 conducts the cold generated by the semiconductor cooling component 200 to the inside of the gloves, achieving a cooling effect. The heat insulation layer 130 keeps the temperature inside the gloves warm. The rubber layer 140 protects the gloves from damage and improves their service life.

[0029] The interlayered pocket 400 is used to hold the ice pack. The inner walls of the interlayered pocket 400 are all cold conduction layers 120. When in use, the ice pack is placed in the interlayered pocket 400. During cold conduction, the cold conduction layers 120 surround the ice pack, accelerating the cooling of the ice pack. At the same time, it does not affect the use of the patient's hands and feet. After the ice pack has cooled down, it can be taken out and given to the patient with fever, which has the function of accelerating the reduction of fever.

[0030] In this embodiment, the semiconductor cooling component 200 includes an outer frame 210, which is inserted into the back of the glove body 100. A semiconductor cooling chip 220 is installed inside the outer frame 210. The bottom surface of the semiconductor cooling chip 220 is attached to the cold conduction layer 120. A heat sink 230 is fixedly attached to the upper surface of the semiconductor cooling chip 220. A temperature sensor 240 is installed at the bottom of the semiconductor cooling chip 220. Both the temperature sensor 240 and the semiconductor cooling chip 220 are electrically connected to the controller 300.

[0031] When the thermoelectric cooler 220 is powered on, the side in contact with the cold conduction layer 120 cools down, while the side connected to the heat sink 230 heats up, generating a higher temperature. The heat sink 230 then dissipates heat from the heated side of the thermoelectric cooler 220. It should be noted that the thermoelectric cooler 220 uses the Peltier effect, which is existing technology and will not be elaborated here.

[0032] When in use, the ice hand and foot gloves are worn on the patient's hands or feet. The controller 300 controls the semiconductor cooling chip 220 to cool the hands or feet. During cooling, the temperature sensor 240 detects the temperature and transmits it to the controller 300. The controller controls the current of the semiconductor cooling chip 220 based on the measured temperature to achieve gradual cooling and heat preservation, thus realizing the effect of ice application and reducing patient discomfort.

[0033] In this embodiment, the cold conductive layer 120 is a filamentous metal cold conductive layer.

[0034] In this embodiment, the controller 300 is a PID controller.

[0035] To precisely control the temperature, the controller 300 uses a PID controller, a very common method. The PID controller adjusts the current based on the temperature information fed back by the temperature sensor 240, thereby controlling the heating or cooling effect of the thermoelectric cooler 22.

[0036] In this embodiment, a zipper 410 is installed between the opening of the interlayer pocket 400 and the glove body 100.

[0037] Zipper 410 is used to prevent cold loss and achieve the function of heat preservation.

[0038] In this embodiment, the temperature sensor 240 is a platinum resistance temperature sensor.

[0039] Platinum resistance temperature sensors have excellent linear temperature response and are often used in high-precision applications.

[0040] In this embodiment, the opening of the glove body 100 is provided with an elastic opening 150.

[0041] The elastic opening 150 is used for heat preservation.

[0042] In this embodiment, the material inside the ice pack is silicone or polymer gel.

[0043] Using silicone or polymer gel will not generate moisture, causing the ice pack to leak, reducing cleaning and maintenance, and improving user comfort.

[0044] The working principle of this medical ice hand and foot glove is as follows:

[0045] In use, the ice pack is placed inside the interlayer pocket 400, and then the ice hand and foot gloves are worn on the patient's hands or feet. After the controller 300 is powered on, the semiconductor cooling chip 220 is controlled to cool. During cooling, the side in contact with the cold conduction layer 120 cools and conducts the cooling to the inside of the hand and foot gloves, achieving a cooling effect. The side connected to the heat sink 230 heats up, generating a higher temperature, which is then dissipated by the heat sink 230 to the heated side of the semiconductor cooling chip 220. The temperature is detected by the temperature sensor 240 at the bottom of the semiconductor cooling chip 220 and transmitted to the controller 300. The controller controls the current of the semiconductor cooling chip 220 based on the measured temperature to achieve gradual cooling and heat preservation, thus realizing the effect of ice pack and reducing patient discomfort.

[0046] While gradually lowering the temperature, the cold conduction layer 120 surrounds the ice pack, accelerating its cooling. At the same time, it does not affect the patient's use of the ice pack's hands and feet. After the ice pack has cooled down, it can be removed and given to the feverish patient for use, thus accelerating the reduction of fever.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
