Description

Technical Field

[0001] This utility model relates to the field of ice therapy technology, specifically to a wearable ice therapy device. Background Technology

[0002] For knee or limb injuries, applying ice within 24 hours of injury (during the acute phase) is crucial. Ice application causes local capillary constriction through low-temperature stimulation, reducing tissue bleeding and inflammatory exudation, thus effectively inhibiting further swelling. Simultaneously, low temperatures reduce the sensitivity of nerve endings, blocking pain signal transmission and providing rapid pain relief. Furthermore, ice application slows the local metabolic rate and inhibits the release of inflammatory mediators such as prostaglandins and histamine, thereby reducing the inflammatory response.

[0003] Traditional ice packs are often applied by wrapping an ice pack in a towel, but this method has significant drawbacks in practical applications: 1. Due to their hard material and fixed shape, ice packs are difficult to fit snugly to the limbs and are prone to slipping off. 2. Ice packs lack a temperature regulation mechanism. When first applied, the local temperature is too low, which may cause frostbite. As the ice pack melts, the temperature will quickly rise back to the ineffective range, resulting in a decrease in the effectiveness of cold therapy. 3. Ice packs need to be repeatedly refilled and replaced after melting, which increases the workload of medical staff. Utility Model Content

[0004] The purpose of this invention is to provide a wearable ice pack device that fits more closely to the patient's limbs and is less likely to slip off, making it easier to control the temperature and duration of the cold compress, and can relieve swelling in the acute phase with good cold compress effect.

The temperature sensor is located inside the ice pack to monitor the temperature of the coolant inside the ice pack. An mounting cavity is provided at the bottom of the cooling chamber inside the mounting box, and a control chip, a Bluetooth module, a timer, and a power supply battery are provided in the mounting cavity.

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] This utility model provides, for example Figure 1-9 The wearable ice pack device shown includes an ice pack component 1, which includes multiple ice packs 11 connected in sequence. Each ice pack 11 is filled with coolant. Cloth pieces 13 are fixed to both sides of the front end of each ice pack 11. Multiple snap fasteners 14 and snap fasteners 15 are fixed to each of the two cloth pieces 13. Adjacent cloth pieces 13 are fastened together by snap fasteners 14 and snap fasteners 15. This allows for the installation of different numbers of ice packs 11 according to the size of the patient's limbs, thus expanding the scope of application.

[0018] At least one strap 3 is provided on both sides of the ice pack component 1. The strap 3 and the adjacent cloth piece 13 are also fastened together by snap fasteners 14 and snap fasteners 15, which facilitates the assembly and disassembly of the strap 3 and the ice pack 11.

[0019] like Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, each ice pack 11 is provided with a cooling mechanism 12 for cooling the coolant on the front side. The cooling mechanism 12 includes a mounting box 121 fixed to the front end of the ice pack 11. A cooling cavity 122 is opened at the top inside the mounting box 121. A semiconductor cooling chip 123 is fixed inside the cooling cavity 122.

[0020] The semiconductor refrigeration chip 123 is a cooling device composed of semiconductors. In principle, the semiconductor refrigeration chip 123 is a heat transfer tool. When current flows through a thermocouple pair formed by connecting an N-type semiconductor material and a P-type semiconductor material, heat transfer will occur between the two ends. Heat will be transferred from one end to the other end, thereby generating a temperature difference and forming hot and cold ends. The cold end of the thermoelectric cooler 123 faces the ice pack 11, and a heat-conducting plate 126 is provided on the side of the thermoelectric cooler 123 near the ice pack 11. The heat-conducting plate 126 is fixed inside the cooling chamber 122 to facilitate temperature transfer between the cold end of the cooling chamber 122 and the coolant in the ice pack 11, that is, the thermoelectric cooler 123 cools the coolant in the ice pack 11. A miniature fan 124 is fixed inside the cooling chamber 122. The miniature fan 124 is located on the hot end side of the thermoelectric cooler 123. A heat dissipation port 125 communicating with the cooling chamber 122 is opened on the side of the cooling chamber 122 away from the ice pack 11. The miniature fan 124 is located on the hot end side of the thermoelectric cooler 123 to dissipate heat from the hot end of the thermoelectric cooler 123 to ensure the normal operation of the thermoelectric cooler 123.

[0021] A temperature sensor 127 is fixed at the bottom of the mounting box 121 near the ice pack 11. The temperature sensor 127 is located inside the ice pack 11 and is used to monitor the temperature of the coolant inside the ice pack 11.

[0022] An installation cavity is also provided at the bottom of the cooling chamber 122 inside the installation box 121. The installation cavity contains a control chip, a Bluetooth module, a timer, and a power supply battery. The temperature sensor 127 is connected to the input end of the control chip. The semiconductor cooling chip 123, the miniature fan 124, and the timer are all located at the output end of the control chip. The control chip is connected to the control terminal via the Bluetooth module, which makes it convenient for personnel to adjust the cooling temperature and time.

[0023] When using, select an appropriate number of ice packs 11 according to the thickness of the patient's limb. Connect multiple ice packs 11 together using snap buttons 14 and snap buttons 15 so that multiple ice packs 11 can wrap around the injured limb of the patient. Then, fasten the strap 3 to the cloth piece 13 on the outermost ice pack 11 using snap buttons 14 and snap buttons 15. After multiple ice packs 11 are wrapped around the injured limb of the patient, tie the strap 3 together or use Velcro to fix it so that this utility model can be worn on the injured limb of the patient. Then, the present invention is connected to a control terminal via a Bluetooth module. The control terminal can be a mobile phone of medical staff. Since the semiconductor cooling chip 123 on each ice pack 11 can be controlled individually, the semiconductor cooling chip 123 on the ice pack 11 that is in contact with the injured limb is activated to cool the coolant in the ice pack 11. The temperature sensor 127 in the ice pack 11 monitors the temperature of the coolant so that the coolant has a suitable temperature for applying cold compress to the affected area. At the same time, the timer controls the cold compress time to ensure that the affected area is adequately cooled.

[0024] like Figure 1 , Figure 2 , Figure 7 , Figure 8and Figure 9 As shown, the present invention also includes a pressurizing component 2, which is located on the rear side of the ice pack component 1. The pressurizing component 2 includes a plurality of airbags 21 connected in sequence. Air tubes 22 are fixed on both sides of each airbag 21. The air tubes 22 between two adjacent airbags 21 are connected by a connector to facilitate communication between the plurality of airbags 21.

[0025] One of the trachea 22 has a balloon 4 on one side. An air outlet tube 41 and an air inlet tube 42 are fixed on the balloon 4. The air outlet tube 41 is connected to the trachea 22 through a connector. Both the air outlet tube 41 and the air inlet tube 42 are fixed with one-way valves. The one-way valve on the air outlet tube 41 only allows air in the balloon 4 to enter the air outlet tube 41, and the one-way valve on the air inlet tube 42 only allows air in the air inlet tube 42 to enter the balloon 4.

[0026] A flexible pressure sensor 24 is fixed on the side of each airbag 21 away from the ice pack assembly 1. The flexible pressure sensor 24 is connected to the input of the control chip and is used to monitor the pressure applied to the affected area.

[0027] When multiple ice packs 11 are connected, the air tubes 22 of the airbags 21 on adjacent ice packs 11 are connected together, and then a tube plug is inserted into the leftmost air tube 22, and the rightmost air tube 22 is connected to the air outlet tube 41 of the balloon 4. During cold compress, the airbag 21 contacts the patient's skin. Then, the balloon 4 is squeezed and released, allowing external air to enter the balloon 4 through the inlet tube 42. The balloon 4 is then squeezed again, and the air in the balloon 4 enters the airbag 21 through the outlet tube 41 and the trachea 22, causing multiple airbags 21 to inflate. When the flexible pressure sensor 24 detects that the pressure is appropriate, the squeezing of the balloon 4 is stopped, the outlet tube 41 on the rightmost trachea 22 is removed, and a tube plug is inserted into the trachea 22. At this time, the inflated airbag 21 not only allows the device to fit more closely to the patient's limb and prevents it from slipping off, but also compresses the affected area. The increased pressure helps reduce intra-tissue bleeding and inflammatory exudation, thereby relieving swelling in the acute phase.

[0028] In addition, cotton pads 23 are fixed on both sides of the rear end of the airbag 21. The cotton pads 23 are located on the back side of the trachea 22. When applying cold compress, the cotton pads 23 separate the trachea 22 from the patient's skin to prevent the trachea 22 from pressing against the patient's skin and causing discomfort.

[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
