Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a device for relieving limb neuropathy. Background Technology
[0002] Chemotherapy-induced peripheral neuropathy (CIPN) is a common drug-dose-limiting adverse reaction in cancer patients during chemotherapy. CIPN is mainly characterized by sensory neuropathy, such as numbness, tingling, and pain, which usually starts from the distal ends of the fingers and toes and may progress to the proximal ends.
[0003] Currently, in clinical practice, surgical glove compression therapy and cryotherapy can prevent and reduce the incidence of peripheral neuropathy induced by certain chemotherapy drugs (such as taxanes). Surgical glove compression therapy reduces blood flow to the hand by applying pressure during chemotherapy, thereby reducing the accumulation of chemotherapy drugs in the nerves of the hand and reducing the occurrence of neurotoxic symptoms. Cryotherapy reduces blood flow by lowering the temperature, thereby reducing the accumulation of chemotherapy drugs in the nerves of the hand.
[0004] Currently, surgical glove compression therapy for chemotherapy-induced peripheral neuropathy typically uses surgical gloves smaller than the patient's hand size. However, this method has some limitations. Because the glove size is fixed, pressure can only be applied to the area constricted by the glove, while other parts of the hand may not receive effective compression. This fixed pressure cannot be adjusted, making it difficult to meet the needs of different patients or the same patient at different stages of treatment. Therefore, the treatment effect is not ideal.

[0005] Based on the above analysis, the present invention aims to provide a device for relieving limb neuropathy, in order to solve the technical problem that existing surgical glove compression therapy cannot adjust the pressure.
[0006] The objective of this utility model is mainly achieved through the following technical solutions:
[0007] A device for relieving limb neuropathy includes an outer layer, an expansion sleeve, a temperature regulating sleeve, a skin contact sleeve, and a limb receiving cavity. The expansion sleeve is disposed inside the outer layer to adjust the size of the limb receiving cavity. The temperature regulating sleeve is disposed on the expansion sleeve to adjust the temperature of the limb receiving cavity. The skin contact sleeve is disposed on the temperature regulating sleeve and abuts against the skin.
[0008] The inflatable sleeve includes an inflatable balloon layer, a limiting plate, and a compression plate. The inflatable balloon layer is inflatable. The limiting plate is fixedly disposed on one side of the inflatable balloon layer to restrict the inflatable balloon layer from expanding away from the limb receiving cavity. The compression plate is fixedly disposed on the other side of the inflatable balloon layer to press against the skin as the inflatable balloon layer expands.

[0011] Furthermore, the limiting plate includes a limiting plate body and an elastic connecting strip, the elastic connecting strip being fixedly disposed between adjacent limiting plate bodies.
[0012] Furthermore, the temperature regulating sleeve includes a first sleeve, a second sleeve, and a medium tube. The first sleeve is sleeved on the outside of the second sleeve, and the medium tube is disposed between the first sleeve and the second sleeve. The medium tube is used to hold the temperature regulating medium.
[0013] Furthermore, the skin contact sheath includes a contact layer body and contact protrusions, the contact protrusions being fixedly disposed on the surface of the contact layer body, and the contact protrusions being pebble-shaped.
[0014] Furthermore, the limb neuropathy relief device also includes a fastening strap, which is fixedly mounted on the outer layer for binding the limb.

[0020] (1) The limb neuropathy relief device of this utility model includes an outer layer, an expansion sleeve, a temperature regulating sleeve, a skin contact sleeve, and a limb receiving cavity. The expansion sleeve includes an expansion balloon layer, a limiting plate, and a compression plate. The expansion balloon layer can expand. The limiting plate is fixedly disposed on one side of the expansion balloon layer to limit the expansion of the expansion balloon layer away from the limb receiving cavity.

[0041] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.
[0042] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments.
[0043] like Figure 1 and Figure 2 As shown, this utility model embodiment provides a device for relieving limb neuropathy. The device includes an outer layer 1, an expansion sleeve 2, a temperature regulating sleeve 3, a skin contact sleeve 4, and a limb receiving cavity 5. The expansion sleeve 2 is disposed inside the outer layer 1 to adjust the size of the limb receiving cavity 5. The temperature regulating sleeve 3 is disposed on the expansion sleeve 2 to adjust the temperature of the limb receiving cavity 5. The skin contact sleeve 4 is disposed on the temperature regulating sleeve 3 and abuts against the skin. The expansion sleeve 2 includes an expansion balloon layer 21, a limiting plate 22, and a compression plate 23. The expansion balloon layer 21 is inflatable. The limiting plate 22 is fixedly disposed on one side of the expansion balloon layer 21 to limit the expansion of the expansion balloon layer 21 away from the limb receiving cavity 5. The compression plate 23 is fixedly disposed on the other side of the expansion balloon layer 21 to press the skin as the expansion balloon layer 21 expands.
[0044] Specifically, the outermost layer 1, as the outermost layer of the entire device, protects the internal structure and provides support. The expansion sleeve 2, for example, can be attached inside the outer layer 1 to adjust the size of the limb receiving cavity 5. When the expansion sleeve 2 expands towards the limb receiving cavity 5, the limb receiving cavity 5 shrinks, thus compressing the limb. The temperature regulating sleeve 3 is located on the expansion sleeve 2 to regulate the temperature of the limb receiving cavity 5. Therefore, depending on the patient's specific condition and treatment needs, the temperature inside the limb receiving cavity 5 can be adjusted to a suitable range through heating or cooling. For example, when using cryotherapy, the temperature regulating sleeve 3 outputs cold energy to cool the limb. The cooling output is continuous and stable. The skin contact layer 4 is placed on the temperature regulating layer 3 and comes into direct contact with the patient's skin. Preferably, the skin contact layer 4 is breathable and elastic to reduce skin irritation and friction, while also providing a certain cushioning effect to protect the skin from direct pressure from components such as the compression plate 23. The limb receiving cavity 5 is the space inside the device used to accommodate the patient's limbs, such as the hands and feet. Its size and shape can be adapted and adjusted according to different limb parts (such as arms, legs, etc.) to ensure that the patient can comfortably place their limbs during use. In summary, the limb neuropathy relief device relieves peripheral neuropathy in the limbs through compression therapy and temperature therapy.
[0045] The inflatable balloon layer 21 can expand, for example, by inflating or filling with fluid to change its volume, thereby altering the size of the limb receiving cavity 5 to accommodate patients with different limb sizes. This allows the device to fit snugly against the limb, providing better support and compression. The limiting plate 22 is fixedly disposed on one side of the inflatable balloon layer 21, primarily to restrict the expansion of the inflatable balloon layer 21 away from the limb receiving cavity 5. The compression plate 23 is fixedly disposed on the other side of the inflatable balloon layer 21 and moves towards the limb as the inflatable balloon layer 21 expands, thereby pressing against the skin and applying a certain amount of pressure to the neuropathy site, which helps to relieve the pain symptoms caused by neuropathy. By allowing the inflatable balloon layer 21 to expand, limiting one side of the inflatable balloon layer 21 with the limiting plate 22, and pressing against the skin with the compression plate 23, the pressure of the compression plate 23 can be adjusted by the expansion of the inflatable balloon layer 21. This solves the technical problem that existing surgical glove compression therapy cannot adjust the pressure.
[0046] In a preferred embodiment of this utility model, such as Figure 2As shown, the inflatable balloon layer 21 includes inflatable balloons 211, which are interconnected and have flow ports for fluid inflow and / or outflow. Multiple inflatable balloons 211 are connected in the transverse and longitudinal directions to form a layer. For example, the inflatable balloons 211 can be made of synthetic rubber. Fluids (such as gas or liquid) can enter or leave the inflatable balloons 211 through the flow ports, thereby realizing the expansion or contraction of the balloons. The simultaneous expansion or contraction of multiple inflatable balloons 211 enables the inflatable balloon layer 21 to provide stable and uniform pressure.
[0047] In a preferred embodiment of this utility model, such as Figure 2 As shown, the compression plate 23 includes a compression plate unit 231, which is fixedly mounted on the inflatable balloon 211 and abuts against the temperature regulating sleeve 3. The compression plate 23 is located between the inflatable balloon 211 and the limb skin. When the inflatable balloon 211 inflates, the compression plate 23 can move towards the limb as the inflatable balloon 211 inflates, generating appropriate pressure on the skin. For example, the compression plate 23 is made of a material with a certain hardness, such as engineering plastic. By fixing the compression plate unit 231 to the inflatable balloon 211, the compression plate unit 231 can output pressure to different parts of the limb, which can further reduce the blood flow to the hand, thereby reducing the accumulation of chemotherapy drugs in the nerves of the hand and further reducing the occurrence of neurotoxic symptoms.
[0048] In a preferred embodiment of this utility model, such as Figure 3 As shown, the limiting plate 22 includes a limiting plate body 221 and an elastic connecting strip 222. The elastic connecting strip 222 is fixedly disposed between adjacent limiting plate bodies 221. This gives the limiting plate 22 a certain degree of elasticity and flexibility, which can provide stable support when the inflatable balloon 211 is inflated, while allowing a certain degree of deformation to ensure that the inflatable balloon 211 can inflate evenly. For example, the limiting plate body 221 is made of engineering plastic material, and the elastic connecting strip 222 is made of silicone material.
[0049] In a preferred embodiment of this utility model, such as Figure 4 As shown, the temperature regulating sleeve 3 includes a first sleeve 31, a second sleeve 32, and a medium tube 33. The first sleeve 31 is sleeved on the outside of the second sleeve 32, and the medium tube 33 is disposed between the first sleeve 31 and the second sleeve 32. The medium tube 33 is used to hold the temperature regulating medium. The first sleeve 31 and the second sleeve 32 are used to surround the medium tube 33. The medium tube 33 adjusts the temperature by absorbing or dissipating heat.
[0050] In a preferred embodiment of this utility model, such as Figure 5As shown, the skin contact sleeve 4 includes a contact layer body 41 and contact protrusions 42. The contact protrusions 42 are fixedly disposed on the surface of the contact layer body 41 and are pebble-shaped. When the skin contact sleeve 4 comes into contact with the skin, it can provide a more comfortable touch and a better massage effect. By directly contacting the skin through the pebble-shaped contact protrusions 42, combined with the expansion of the expansion balloon layer 21, it can massage the skin.
[0051] In a preferred embodiment of this utility model, such as Figure 1 As shown, the limb neuropathy relief device also includes a fastening strap 8, which is fixedly disposed on the outer layer 1 for binding the limb. For example, the fastening strap 8 is an elastic band.
[0052] In a preferred embodiment of this utility model, such as Figure 6 As shown, the limb neuropathy relief device also includes a regulating pump 6, which is connected to the inflatable balloon layer 21 to inflate or contract the inflatable balloon layer 21. By controlling the inflow and outflow of fluid (such as gas or liquid) through the regulating pump 6, the inflatable balloon layer 21 is inflated or contracted, thereby regulating the pressure within the limb receiving cavity 5 and reducing pain and discomfort caused by neuropathy. Exemplarily, and also for portability, the regulating pump 6 is a micro pump, such as a micro peristaltic pump.
[0053] In a preferred embodiment of this utility model, such as Figure 6 As shown, the limb neuropathy relief device also includes an air conditioner 7, which is connected to the temperature regulating sleeve 3 to regulate the temperature of the limb receiving cavity 5. The air conditioner 7 is a miniature portable air conditioner; as a preferred embodiment, the air conditioner 7 can be a semiconductor cooling chip.
[0054] In a preferred embodiment of this utility model, such as Figure 1 and Figure 6 As shown, the limb neuropathy relief device also includes a controller 9, which is connected to the regulating pump 6 and the air conditioner 7 to send control commands. For example, the controller 9 uses an MCU, such as an STM32F103 chip. The limb neuropathy relief device also includes a temperature sensor, a pressure sensor, and a display screen 91. The temperature sensor and the pressure sensor are both disposed on the skin contact sleeve 4 to collect data. For example, the temperature sensor uses a DS18B20 sensor, and the pressure sensor uses an MPX5010DP sensor. The controller 9 is connected to the temperature sensor and the pressure sensor to receive the collected data. The display screen 91 is fixedly disposed on the outer sleeve 1 and is connected to the controller 9 to display the collected data.
[0055] Based on this, the limb neuropathy relief device also includes a power supply module, which is connected to the controller 9, temperature sensor, pressure sensor and display screen 91 to provide power. An exemplary power supply module uses a storage battery. The regulating pump 6 and the air conditioner 7 can be supplied by the storage battery or mains power. The connection between the regulating pump 6 and the inflatable balloon layer 21 and the connection between the air conditioner 7 and the temperature regulating sleeve layer 3 are both pluggable connections.
[0056] 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 changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
