Description

Technical Field

[0001] The present invention belongs to the field of wearable medical equipment, and in particular relates to a lightweight suspended wearable device for body surface thermal management. Background Art

[0002] In recent years, with people's increasing emphasis on health management, wearable medical devices have gradually become a key development direction in the healthcare field. In addition to monitoring vital signs, wearable medical devices can also be used for disease treatment. For example, non-invasive treatment technologies, including electrotherapy, magnetic therapy, ultrasound therapy, and transdermal drug delivery, have been hot topics in recent research and are also key development areas for wearable therapeutic systems. The skin is the body's first line of defense and largest organ. Compared to traditional treatment methods, thermal therapy can target infected lesions, activate local lymphocytes, and induce systemic immunity, allowing the body's immune system to engage in a "precise counterattack."

[0003] Existing wearable devices for dermatology utilize thermal management with electric heating elements or phase change materials. These garments can adjust their temperature based on the wearer's body temperature, providing a certain level of comfort. However, these technologies often rely on batteries or complex temperature control systems, making the garments heavy and inconvenient to wear for extended periods. They also have limited effectiveness in managing moisture. Moisture-wicking fabrics can effectively wick away sweat, keeping the skin dry. However, these fabrics cannot effectively regulate the skin's surface temperature and can easily accumulate moisture in high-temperature environments, causing discomfort and potentially leading to infection.

[0004] Therefore, there is an urgent need to combine temperature control, moisture management and comfort, which can not only regulate body temperature, but also effectively remove sweat and reduce humidity to prevent skin irritation due to moisture accumulation. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a lightweight suspension wearable device for body surface thermal management, which solves the problems in the existing technology.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] A lightweight, suspended wearable device for body surface thermal management includes an annular bladeless fan disposed on the outside of the body surface, a heating sleeve coaxially disposed at one end of the annular bladeless fan to heat the body surface; a fan air inlet is disposed on one side of the annular bladeless fan, an air flow inlet is formed between the annular bladeless fan and the body surface, and a fan outlet is disposed in the annular bladeless fan;

[0008] When the annular bladeless fan is started, the gas is sent from the fan inlet to the fan outlet to form a low-pressure area, relying on the Bernoulli effect to attract the surrounding air to enter from the air inlet, forming an enhanced airflow.

[0009] Furthermore, a support frame is provided inside the annular bladeless blower to conform to the body surface.

[0010] Furthermore, the heating jacket comprises a three-layer structure, which includes, from the outside to the inside, a thermal insulation and waterproof layer, a metal heating layer, and an insulating protective layer.

[0011] Furthermore, the shell of the annular bladeless fan is a double-layer structure, and a gap is provided at one end of the double-layer structure away from the air inlet to form the fan outlet.

[0012] Furthermore, the annular bladeless fan includes: an air compressor, a main control module, a fan drive module and a heating control module; the main control module controls the opening of the fan drive module and the heating control module to respectively realize the start and stop control of the annular bladeless fan and the heating jacket.

[0013] Furthermore, the annular bladeless blower includes an air pressure feedback module for measuring an internal air pressure value.

[0014] Furthermore, the tail of the heating sleeve is connected to the air outlet, which is a closed air outlet. When the internal air pressure value measured by the air pressure feedback module reaches a threshold, the air flow can break through the closed air outlet and flow out.

[0015] Furthermore, the air outlet is provided with an elastic sealing ring, which automatically adjusts the size of the opening by external force or air pressure change.

[0016] Furthermore, the thermal insulation and waterproof layer is made of rubber-plastic thermal insulation material, the metal heating layer is made of aluminum, and the insulating protective layer is made of silicone rubber.

[0017] Furthermore, the air pressure feedback module includes an air pressure sensor to measure the air pressure inside the device.

[0018] Beneficial effects of the present invention:

[0019] 1. The lightweight suspended wearable device designed by the present invention fits the human body model, avoids the limitation of being too large, and is more portable.

[0020] 2. Designed with patient safety in mind, the device incorporates a three-layer structure that integrates heat preservation, heating, and insulation to achieve safe temperature control. The outer layer is a thermally insulating, waterproof layer that reduces internal heat loss and prevents liquid penetration. The center layer is a metal heating layer that generates Joule heat through electrical conduction, gently heating the skin surface from all angles. The inner layer is an insulating protective layer to prevent electrical shock during use. The three-layer structure works together to effectively activate the skin's immune system, promote blood circulation, and enhance local self-repair capabilities.

[0021] 3. To prevent bacterial infection, this invention not only provides heat therapy but also manages humidity. The Bernoulli effect of the circular bladeless fan multiplies airflow, removing sweat from the skin's surface. This effectively manages moisture while providing temperature control, preventing the adverse effects of excessive humidity on skin health and promoting self-repair and recovery. The overall design combines temperature control, moisture management, and comfort, fully addressing the specific needs of patients with skin diseases and providing an effective treatment aid.

DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0029] like Figure 1As shown, a lightweight suspension wearable device for body surface thermal management includes an annular bladeless fan 2 mounted on the outside of a human body 1, and a support frame 5 is provided inside the annular bladeless fan 2 to conform to the human body; after the annular bladeless fan 2 is started, air begins to flow toward the body surface;

[0030] A heating sleeve 6 is coaxially provided at one end of the annular bladeless fan 2 for heating the body surface; Figure 2 As shown, the heating sleeve 6 has a three-layer structure, wherein the outermost layer is a thermal insulation and waterproof layer 8 to reduce internal heat loss and prevent liquid penetration; the middle layer is a metal heating layer 9, which generates Joule heat through current conduction and gently heats the skin surface in all directions; the innermost layer is an insulating protective layer 10 to prevent the patient from being electrocuted during use of the device;

[0031] A fan air inlet 3 is provided on one side of the annular bladeless fan 2, and a wind inlet 4 is formed between the annular bladeless fan 2 and the skin of the human body 1. The tail of the heating sleeve 6 is connected to the wind outlet 7. Figure 3 As shown, the shell of the annular bladeless fan 2 is a double-layer structure, and a gap is provided at the end of the double-layer structure away from the air inlet 4 to form a fan outlet 11. After the airflow enters the double-layer structure from the fan inlet 3, it flows out from the fan outlet 11 at high speed.

[0032] like Figure 3 As shown, the annular bladeless fan 2 includes: an air compressor 12, a power module 13, a main control module 14, a fan drive module 15, a heating control module 16 and an air pressure feedback module 17; wherein: the power module 13 supplies power to the fan drive module 15 and the heating control module 16; the main control module 14 controls the opening of the fan drive module 15 and the heating control module 16 to respectively realize the start and stop control of the annular bladeless fan 2 and the heating sleeve 6; when the annular bladeless fan 2 is working, the air compressor 12 first transmits the gas from the fan air inlet 3 to the fan air outlet 11 to form a low-pressure area, and relies on the Bernoulli effect to attract more surrounding air to enter from the air flow inlet 4, forming a more concentrated and powerful airflow;

[0033] When working, the annular bladeless fan 2 displays the internal air pressure value through the air pressure feedback module 17, and controls the opening and closing of the air outlet 7 according to the internal air pressure value, on the one hand to avoid excessive air pressure inside the wearable device, and on the other hand to avoid excessive heat loss inside the wearable device.

[0034] When in use, the lightweight suspension wearable device is first worn on a human body 1 (such as an arm, leg, etc.). Then, the main control module 14 turns on the fan drive module 15 and the heating control module 16. The fan drive module 15 controls the annular bladeless fan 2 to start working. The air compressor 12 first transmits gas from the fan air inlet 3 to the fan air outlet 11. Due to the narrowness of the fan air outlet 11, the air is ejected at high speed to form a low-pressure area. Relying on the Bernoulli effect, more surrounding air is attracted to enter from the air flow inlet 4, forming a more concentrated and powerful airflow. This not only allows the airflow to carry away sweat from the skin surface and reduce humidity, but also helps maintain local temperature stability. When the heating control module 16 controls the heating sleeve 6 to work, it uses the Joule heating effect to provide stable heat, which can achieve uniform local temperature distribution and meet the thermal effect requirements in skin disease treatment. The annular bladeless fan 2 and the heating sleeve 6 cooperate with each other to achieve precise control of the temperature and humidity of the lightweight suspension device, improve treatment effects, and enhance patient comfort and safety. The wind outlet 7 at the end is designed to be closed, and the air pressure feedback module 17 displays the internal air pressure value. Only when the internal air pressure value reaches a certain threshold value can the air flow break through the seal of the wind outlet 7 at the end and flow out. The setting of the threshold value will not cause heat to be lost too quickly. The inflow and outflow of air can take away sweat from the human body surface, which can avoid irritation caused by moist skin, keep the skin dry, reduce the negative impact of moisture on skin diseases, and improve the treatment effect.

[0035] In this embodiment, the thermal insulation and waterproof layer 8 is made of rubber-plastic thermal insulation material, the metal heating layer 9 is made of aluminum, and the insulating protective layer 10 is made of silicone rubber.

[0036] In this embodiment, the air pressure feedback module 17 includes an air pressure sensor to measure the air pressure inside the device.

[0037] like Figure 4 As shown, in this embodiment, an elastic sealing ring 18 is provided at the air outlet 7. The diameter of the elastic sealing ring 18 can be naturally compressed or expanded according to the circumference of the wearer's arm to ensure a comfortable fit. When the air pressure reaches a set threshold, the elastic portion of the sealing ring is stretched to form a larger opening, allowing air to flow out.
