Description

Technical Field

[0001] This utility model relates to the field of cold compress technology, and more specifically, to a composite cold compress. Background Technology

[0002] Cold compresses are a common medical adjunct, widely used to relieve localized pain, inflammation, and fever on the face. With technological advancements, the manufacturing process of cold compresses has gradually evolved towards composite structures. High-molecular-weight gel materials, due to their excellent hydration properties and natural cooling components, have become a crucial component of cold compresses. The high-molecular-weight gel removes heat through vaporization, achieving a localized cooling effect on the face. Simultaneously, the drug components in the gel, combined with the hydrogel, can effectively promote rapid penetration of the drug through the skin's fat layer and into the subcutaneous tissue, directly reaching the lesion site to relieve pain and provide therapeutic effects. Due to the slow-release characteristics of the drug, composite cold compresses not only provide continuous therapeutic effects but also gradually release the drug through transdermal absorption, reducing patient discomfort.

[0003] However, existing cold compresses face some significant problems in practical applications. While traditional cold compresses can quickly remove heat and achieve a cooling effect, their cooling capacity is lost rapidly, making it difficult to provide a prolonged cooling effect, especially when continuous cooling is required. Furthermore, most cold compresses are designed for single use only, leading to resource waste and increased costs for patients. Therefore, improving the duration of cooling effect and developing reusable, more cost-effective products has become a pressing issue. This need has driven innovation in cold compress technology, aiming to improve the durability of the cooling effect and increase the ease of use and cost-effectiveness of the products.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a composite cold compress patch with the following beneficial effects:

[0017] 1. The heat exchange mechanism of the composite cold compress, through the inclusion of a water storage bag and a related liquid delivery system, effectively achieves internal cooling through water injection, thereby promoting a continuous cooling effect. This mechanism utilizes air pressure to push a push plate away from the sealing groove, allowing the cold water in the storage bag to drain smoothly. The temperature of the cold water is regulated through a drain pipe, maintaining a constant temperature for the cold compress. This design ensures that the cold compress provides a stable cooling effect during continuous use, meeting the patient's need for prolonged cold compresses during treatment.

[0018] 2. The sealing mechanism design further enhances the stability and safety of the cold compress during use. The push plate, through the cooperation of the screw and transmission sleeve, achieves pressure regulation and automatic disengagement of the sealing ring during water injection into the reservoir bag, thus preventing water leakage or uncontrolled cold water temperature. The presence of the compression spring also ensures that a certain pressure can be overcome during drainage, precisely controlling the cooling time and effect of the cold compress, making the use process more accurate and reliable.

[0019] 3. The positioning mechanism, through a precise adjustment system, ensures accurate control of liquid flow during the heat exchange process. The cooperation between the positioning block and the positioning groove guarantees smooth flow of the drain pipe and liquid, avoiding poor cooling effect caused by inaccurate positioning. The combination of the tension spring and the pressure block allows for flexible adjustment of the cooling effect of the cold compress to meet the needs of different patients. This design not only provides stable cooling but also improves flexibility and safety during use. Attached Figure Description

[0030] A positioning mechanism is provided at the top of the drain pipe 4. The positioning mechanism includes a positioning block 12, a positioning groove 13, a pressure block 14, and a tension spring 15. The positioning block 12 has multiple sets that slide on the outer wall of the drain pipe 4. The positioning groove 13 has multiple sets that are distributed on the outer wall of the mating block 7. The pressure block 14 has multiple sets that abut against the top of the multiple sets of positioning blocks 12. The tension spring 15 is connected to the inner side of the multiple sets of pressure blocks 14 and is connected to the outer wall of the drain pipe 4. It is used to achieve stable fixation between the drain pipe 4 and the mating block 7 through elastic tension and mechanical limiting, so as to prevent displacement during the cold compress process.

[0031] A sealing ring 16 is provided on the outer side of the push plate 5, and a sealing groove 17 is provided inside the drain pipe 4. The sealing ring 16 abuts against the sealing groove 17. The liquid isolation between the push plate 5 and the drain pipe 4 is achieved through the sealing structure to prevent liquid leakage and ensure the airtightness of the cold compress system.

[0032] A limiting sleeve 18 is fixedly installed inside the drain pipe 4. A limiting hole 19 is opened on the limiting sleeve 18. A limiting block 20 is fixedly installed on the top surface of the push plate 5. Multiple sets of limiting holes 19 and limiting blocks 20 are provided and slidably connected. The movement range of the push plate 5 is limited by the cooperation of the limiting holes 19 and the limiting blocks 20, so as to achieve precise control of the liquid propulsion stroke.

[0033] The limiting sleeve 18 has through holes 21, and multiple sets of through holes 21 are provided. The limiting sleeve 18 is movably connected to the screw 6. The through holes 21 enable the screw 6 and the limiting sleeve 18 to form an adjustable connection structure, thereby realizing the flexible adjustment and locking function of the structural position.

[0034] The inner wall of the drain pipe 4 is provided with a slide bar 22. Multiple slide bars 22 are provided and are slidably connected to the transmission sleeve 8. The slide bar 22 guides the movement of the transmission sleeve 8, making the transmission process smooth and stable, reducing friction and deviation, and improving transmission efficiency and system stability.

[0035] The bottom ends of multiple positioning blocks 12 and the outer sides of positioning grooves 13 are all set in an arc shape and abut against each other. The arc structure enhances the contact area and adaptability between positioning blocks 12 and positioning grooves 13, thereby improving the stability and wear resistance of the positioning device.

[0036] The top of the cold compress is connected to a first strap 23, and a plug 24 is fixed on the first strap 23. The bottom of the cold compress body 1 is connected to a second strap 25, and a plug hole 26 is opened on the second strap 25. Multiple sets of plug holes 26 are provided. Through the snap-fit ​​structure between the plug 24 and the plug hole 26, the cold compress body 1 can be fixedly worn and its tightness can be adjusted, thereby improving the ease of wearing and fit.

[0037] In this embodiment, during use, the cold compress body 1 is fixed to the patient's head by inserting the insert 24 into the insert hole 26 and placing the cold compress body 1 on the patient's forehead. Then, the inlet 3 is connected to the external cold water delivery pipe to inject water into the water storage bag 2. During the water injection process, the air pressure in the water storage bag 2 pushes the push plate 5 to make the sealing ring 16 disengage from the sealing groove 17. At the same time, the screw 6 drives the transmission sleeve 8 to slide and squeeze the pressure spring 9 to overcome the preset threshold. At the same time, it pushes the mating block 7 and the rotating plate 11 to separate from the drain pipe 4 to form a flow channel, so that the air pressure in the water storage bag 2 is discharged. At the same time, after the temperature of the cold water in the water storage bag 2 rises, it is discharged through the drain pipe 4.

[0038] More specifically, when the preset threshold of the drain pipe 4 needs to be adjusted, the rotating plate 11 drives the mating block 7 to rotate, and pushes the positioning block 12 to disengage through multiple sets of positioning grooves 13 and pushes the pressure block 14, and stretches multiple sets of tension springs 15. The mating block 7 drives the screw 6 to rotate and engage with the transmission sleeve 8 through a threaded connection, so that the transmission sleeve 8 squeezes the pressure spring 9 to increase the preset threshold. Then, the multiple sets of tension springs 15 pull the pressure block 14 to push the positioning block 12 to abut against the positioning groove 13 to position the mating block 7.

[0039] In summary, when using or operating the entire device: During use, the cold compress body 1 is fixed to the patient's head by inserting the insert block 24 into the insert hole 26 and placing the cold compress body 1 on the patient's forehead. Then, the inlet 3 is connected to the external cold water delivery pipe to inject water into the water storage bag 2. During the water injection process, the air pressure in the water storage bag 2 pushes the push plate 5 to make the sealing ring 16 disengage from the sealing groove 17. At the same time, the screw 6 drives the transmission sleeve 8 to slide and squeeze the pressure spring 9 to overcome the preset threshold. Simultaneously, it pushes the mating block 7 and the rotating plate 11 to separate from the drain pipe 4 to form a flow channel, so that the air pressure in the water storage bag 2 is discharged. At the same time, after the temperature of the cold water in the water storage bag 2 rises, it is discharged through the drain pipe 4.

[0040] However, when the preset threshold of the drain pipe 4 needs to be adjusted, the rotating plate 11 drives the mating block 7 to rotate, and pushes the positioning block 12 to disengage through multiple sets of positioning grooves 13 and pushes the pressure block 14, and stretches multiple sets of tension springs 15. The mating block 7 drives the screw 6 to rotate and engage with the transmission sleeve 8 through a threaded connection, so that the transmission sleeve 8 squeezes the pressure spring 9 to increase the preset threshold. Then, the multiple sets of tension springs 15 pull the pressure block 14 to push the positioning block 12 to abut against the positioning groove 13 to position the mating block 7.

For all the fixed connections mentioned above, welding is preferred.
