Description

Technical Field

[0001] This invention relates to the field of ice pack equipment technology, specifically to an ice pack device for soft tissue injuries during military training. Background Technology

[0002] During military training, running, jumping, tactical confrontation, and weight-bearing exercises can easily cause soft tissue injuries such as sprains and contusions to the joints and muscles of soldiers' limbs. In the acute phase of the injury, ice packs are commonly used in clinical practice to constrict local blood vessels, reduce swelling, relieve pain, and inhibit inflammatory exudation.

[0003] Current ice pack methods mostly involve directly applying ordinary ice packs or ice towels to the affected area. However, these methods have several drawbacks in military field training environments: ordinary ice packs lack a fixed structure, making them prone to shifting and slipping during limb movement, and difficult to maintain a stable position during casualty transport and temporary treatment in military training scenarios. Melting ice packs can easily cause condensation and leakage, wetting training uniforms and potentially leading to secondary frostbite in low-temperature outdoor environments. Direct contact between ice and skin, without temperature buffering, can easily cause frostbite. Traditional ice packs lack breathable cushioning padding, resulting in poor comfort during prolonged use. Existing ice pack equipment has an integrated structure; the padding and cold storage components cannot be disassembled and replaced, making overall cleaning difficult and unsuitable for large-scale emergency response scenarios in military training. Summary of the Invention

[0004] The purpose of this invention is to provide an ice pack device for soft tissue injuries in military training, in order to solve the problems mentioned in the background art, such as ice packs easily producing condensation and leakage after melting, wetting training clothes, easily causing secondary frostbite in low-temperature outdoor environments, ice blocks directly contacting the skin, the ice temperature not being buffered, easily causing frostbite, and traditional ice packs lacking breathable cushioning padding, resulting in poor comfort during long-term ice application.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an ice pack device for soft tissue injuries in military training, comprising a tightening clamp, an inner padding patch installed inside the tightening clamp, a heat insulation protective component assembled and installed outside the inner padding patch, and the heat insulation protective component being able to be completely removed from the inside of the tightening clamp.

[0006] The heat-insulating protective component includes a heat-insulating shell, which, together with an inner pad, forms a placement cavity. Ice pillars are arranged inside the placement cavity. The ice pillars release low-temperature cold energy, which passes through the heat-insulating layer and vents to act on the soft tissue of the affected area. The heat-insulating layer forms a buffer layer to prevent the ice pillars from directly contacting the skin and causing frostbite. The vents ensure a small amount of air circulation on the skin surface, reducing sweating. The outer heat-insulating shell prevents external heat from entering the placement cavity, slowing down the melting rate of the ice pillars and prolonging the duration of the ice application.

[0007] Furthermore, the heat insulation shell is detachably installed on the outer layer of the tightening clamp. Multiple ice pillars are fitted into the inner wall of the heat insulation shell and surround the inner padding. Each ice pillar is a prefabricated, individually replaceable cold storage component. By using a heat insulation shell to protect the placement cavity, heat exchange with the external environment is isolated, slowing down the melting rate of the ice pillars. Compared to traditional ice packs, this effectively extends the duration of a single ice application, reduces the frequency of ice source replacement in the field, and is suitable for scenarios with limited supply conditions during military training.

[0008] Furthermore, the heat insulation shell is an arc-shaped rigid shell, the placement cavity is an accommodating cavity open towards the inner pad, and the ice pillars are made of polymer cold-storing gel material, with the ends of multiple ice pillars abutting against the outer side of the inner pad. By setting up a leak-proof protective strip, in conjunction with the silicone sealing gasket inside the mounting groove, the gaps at the inner pad fitting assembly position are sealed. The condensate after the ice pillars melt is confined inside the equipment, preventing leakage and wetting of training clothing, and avoiding secondary frostbite caused by damp cold in low-temperature outdoor environments.

[0009] Furthermore, the tightening clamp includes a leak-proof protective belt. The surface of the leak-proof protective belt is provided with elastic straps. Two sets of elastic straps are provided, each fixed to the upper and lower ends of the leak-proof protective belt. Each set of elastic straps has a snap-fit ​​buckle at both ends. When the icicle melts and produces condensation, the condensation is confined to the inside of the leak-proof protective belt. A silicone sealing gasket seals the gap between the connecting strip and the mounting groove, preventing condensation from seeping out and wetting clothing. After the equipment is worn, the injured person can perform small limb movements, and the elastic straps and snap-fit ​​buckles prevent the equipment from falling off or shifting.

[0010] Furthermore, the leak-proof protective belt is an arc-shaped semi-enclosed shell structure, and the leak-proof protective belt is made of rigid engineering plastic. The elastic strap is a high-elasticity nylon webbing. The upper and lower sets of elastic straps wrap around the limb and are locked together by snap-fit ​​buckles.

[0011] Furthermore, the tightening clamping component includes a clamping bend, the inner side of which has an installation groove. A retaining strip is engaged with the surface of the installation groove, and a silicone sealing gasket is embedded inside the retaining strip. By setting up the tightening clamping component, the limb is secured by an elastic strap and a retaining buckle. The C-shaped clamping bend adapts to the cylindrical shape of the limbs, making it less likely for the equipment to slip or shift during the transport of military casualties or during minor movements. It eliminates the need for personnel to hold it for support, meeting the needs of emergency response in field training. The elastic strap is stretchable and adjustable to accommodate arms and legs of different thicknesses.

[0012] Furthermore, the locking strip is integrally formed along the inner edge of the clamping bend, and the locking strip cooperates with the mounting groove to achieve the limiting and locking of the connecting strip. The clamping bend is set as a C-shaped arc structure, and the clamping bend is wrapped around the outside of the limb by an elastic strap. The pre-frozen heat insulation protective component is installed into the inner space of the tightening clamping component, with the heat insulation shell facing outward and the ice column facing inward. Then, the connecting strips on both sides of the inner pad are aligned with the mounting groove on the inner side of the clamping bend of the leak-proof protective strip, and pushed into the mounting groove along the locking strip to complete the locking and fixing. After assembly, the end face of the ice column is attached to the outer side of the heat insulation pad of the inner pad, and the coldness of the ice column is transmitted to the affected area through the heat insulation pad and the vent holes.

[0013] Furthermore, the silicone sealing pad is installed in the groove bottom, and the silicone sealing pad is made of medical-grade silicone. The silicone sealing pad is pressed and adhered to the outer periphery of the limb to achieve a leak-proof seal at the assembly position of the inner padding. The assembled device is then wrapped around the injured limb with the inner surface of the insulating padding aligned with the swollen area. The upper and lower elastic straps are pulled around the outer periphery of the limb, and the stretch of the elastic straps is adjusted according to the limb's thickness. The buckles on both sides are then fastened accordingly. The elastic straps, relying on their own elasticity, pull the leak-proof protective straps and the inner padding to hold the limb tightly, completing the overall clamping and tightening. The clamping bend has a C-shaped arc structure, which adapts to the cylindrical shape of the limb and will not cause localized hard pressure injuries.

[0014] Furthermore, the inner pad includes a connecting strap, the surface of which is connected to an insulating pad layer, and the surface of the insulating pad layer is arrayed with ventilation holes. After the ice application process is completed, press the buckle to release the fastener, untie the elastic strap to remove the entire device, and directly pull the entire heat insulation protective component out of the tightening clamp. After the ice column is consumed, a brand new pre-cooled heat insulation protective component can be replaced to achieve rapid continuation of ice application. Apply outward pulling force to the inner pad, and the connecting strap will disengage from the mounting groove, completing the removal of the inner pad.

[0015] Furthermore, the connecting strip is detachably snapped into the mounting groove. The thermal insulation pad is made of EPE pearl cotton, and the ventilation holes are evenly distributed throughout the strip of the thermal insulation pad. The connecting strip is a rigid plastic edge strip, and the connecting strip is sewn to the edge of the thermal insulation pad. The disassembled inner pad can be cleaned and disinfected separately, and the leak-proof protective strip and thermal insulation protective components can be wiped and disinfected. Each component is disassembled and processed, suitable for repeated use by wounded soldiers in military multi-person training. After all components are cleaned, the inner pad is re-snapped, and a new thermal insulation protective component is installed, ready for the next use.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] (i) The ice pack for soft tissue injury in this military training is designed with a tightening clamp and elastic straps with buckles to hold and lock the limbs. The C-shaped clamping plate is adapted to the cylindrical shape of the limbs. The equipment is not easy to slip or move during the transfer of military wounded soldiers or during minor activities. It does not require personnel to hold it for support and meets the needs of emergency treatment at the field training site. The elastic straps can be stretched and adjusted to fit arms and legs of different thicknesses.

[0018] (ii) The ice pack equipment for soft tissue injury in this military training is designed with a leak-proof protective belt and a silicone sealing gasket inside the installation slot. The gap is sealed at the joint of the inner pad and the condensate after the ice column melts is contained inside the equipment and will not leak out and wet the training clothes, thus avoiding secondary frostbite caused by dampness and cold in the low temperature environment in the field.

[0019] (iii) The ice pack equipment for soft tissue injuries in this military training uses a removable inner pad and an insulating pad to act as a buffer between the cold source and the skin, preventing hard contact with the ice column. The insulating pad has ventilation holes to ensure skin breathability, reduce stuffiness and discomfort, and balance the cooling effect of ice pack with skin safety, avoiding the problem of frostbite caused by prolonged ice pack.

[0020] (iv) The ice pack for soft tissue injury in this military training is equipped with a heat-insulating shell with heat-insulating protective components. The heat-insulating shell covers the placement cavity, isolates the heat exchange with the external environment, and slows down the melting rate of the ice column. Compared with traditional ice packs, it effectively prolongs the single ice pack time, reduces the frequency of ice source replacement in the field environment, and is suitable for scenarios with limited supply conditions in military training.

[0021] (v) The ice pack equipment for soft tissue injuries used in this military training is designed with fully detachable components for easy disinfection and replacement, making it suitable for batch emergency use. The inner padding is connected to the leak-proof protective belt via a connecting strap, allowing for quick assembly and disassembly. The heat insulation and protective components can be removed as a whole, and the ice column can be replaced as a whole. Each component can be cleaned and disinfected separately, and the inner padding can be disassembled and cleaned individually after it becomes contaminated with sweat or dirt. This eliminates the need for the entire equipment to be scrapped, making it suitable for the cyclical treatment of multiple soft tissue injury patients in military training, thus reducing usage costs.

Detailed Implementation

[0031] Example 1, as Figures 1 to 8 As shown, the present invention provides a technical solution: an ice pack device for soft tissue injury in military training, including a tightening clamp 1, an inner pad 3 installed inside the tightening clamp 1, a heat insulation protective component 2 assembled and installed outside the inner pad 3, and the heat insulation protective component 2 can be completely removed from the inside of the tightening clamp 1.

[0032] The heat-insulating protective component 2 includes a heat-insulating shell 22, which, together with the inner padding 3, forms a placement cavity 23. Ice pillars 21 are arranged inside the placement cavity 23. The ice pillars 21 release low-temperature cold energy, which passes through the heat-insulating padding layer 32 and the venting holes 33 to act on the soft tissue of the affected area. The heat-insulating padding layer 32 forms a buffer layer to prevent the ice pillars 21 from directly contacting the skin and causing frostbite. The venting holes 33 ensure a small amount of air circulation on the skin surface, reducing sweating. The outer heat-insulating shell 22 isolates external environmental heat from entering the placement cavity 23, reducing the melting rate of the ice pillars 21 and prolonging the duration of the ice application.

[0033] The heat insulation shell 22 is detachably installed on the outer layer of the tightening clamp 1. Multiple ice pillars 21 are fitted to the inner wall of the heat insulation shell 22 and surround the inner padding 3. Each ice pillar 21 is a prefabricated cold storage component that can be replaced individually. The heat insulation shell 22, installed by the heat insulation protective component 2, encloses the placement cavity 23, isolating it from external heat exchange and slowing the melting rate of the ice pillars 21. Compared to traditional ice packs, this effectively extends the duration of a single ice application, reduces the frequency of ice source replacement in the field, and is suitable for scenarios with limited supply conditions during military training.

[0034] The heat insulation shell 22 is an arc-shaped rigid shell, the placement cavity 23 is a receiving cavity open towards the inner pad 3, and the ice pillars 21 are made of polymer cold-storing gel material, with the ends of multiple ice pillars 21 abutting against the outside of the inner pad 3. By setting a leak-proof protective strip 11, and cooperating with the silicone sealing gasket 112 inside the mounting groove 114, the gaps at the snap-fit ​​assembly position of the inner pad 3 are sealed, and the condensate after the ice pillars 21 melt is confined inside the equipment, preventing leakage and wetting of training clothes, and avoiding secondary frostbite caused by damp cold in the low-temperature environment of the field.

[0035] Example 2, based on Example 1, such as Figures 3 to 6 As shown, the tightening clamp 1 includes a leak-proof protective belt 11. The surface of the leak-proof protective belt 11 is provided with elastic straps 12. Two sets of elastic straps 12 are provided, each fixed to the upper and lower ends of the leak-proof protective belt 11. Each set of elastic straps 12 is equipped with a snap-fit ​​buckle 13 at both ends. When the icicle 21 melts and produces condensation, the condensation is confined to the inside of the leak-proof protective belt 11. The silicone sealing gasket 112 seals the gap between the connecting strip 31 and the mounting groove 114, preventing condensation from seeping out and wetting clothing. After the equipment is worn, the injured person can perform small limb movements, and the elastic straps 12 and snap-fit ​​buckles 13 prevent the equipment from falling off or shifting.

[0036] The leak-proof protective belt 11 is an arc-shaped semi-enclosed shell structure, and the leak-proof protective belt 11 is made of rigid engineering plastic. The elastic strap 12 is a high-elasticity nylon webbing. The upper and lower sets of elastic straps 12 are wrapped around the limb and then locked together by snap fasteners 13.

[0037] The tightening clamp 1 includes a clamping bend 113. An installation groove 114 is formed on the inner side of the bend of the clamping bend 113. A locking strip 111 is engaged with the surface of the installation groove 114, and a silicone sealing gasket 112 is embedded inside the locking strip 111. By setting the tightening clamp 1, the limb is secured by the elastic strap 12 and the locking buckle 13. The C-shaped clamping bend 113 adapts to the cylindrical shape of the limbs, preventing the equipment from slipping or shifting during the transport of military casualties or minor activities. It eliminates the need for personnel to hold it for support, meeting the needs of emergency response in field training. The elastic strap 12 is stretchable and adjustable to accommodate arms and legs of different thicknesses.

[0038] The clip 111 is integrally formed along the inner edge of the clamping bend 113. The clip 111 cooperates with the mounting groove 114 to realize the limiting and locking of the connecting band 31. The clamping bend 113 is set as a C-shaped arc structure. The clamping bend 113 is wrapped around the outside of the limb by the elastic strap 12. The pre-frozen heat insulation protective component 2 is installed into the inner space of the tightening clamping component 1, with the heat insulation shell 22 facing outward and the ice column 21 facing inward. Then, the connecting bands 31 on both sides of the inner pad 3 are aligned with the mounting groove 114 on the inner side of the clamping bend 113 of the leak-proof protective band 11. The clip 111 is pushed into the mounting groove 114 to complete the locking and fixing. After assembly, the end face of the ice column 21 is attached to the outer side of the heat insulation pad 32 of the inner pad 3. The cold energy of the ice column 21 is transmitted to the affected area through the heat insulation pad 32 and the vent 33.

[0039] The silicone sealing pad 112 fills the bottom of the mounting groove 114. The silicone sealing pad 112 is made of medical-grade silicone. The silicone sealing pad 112 is pressed and adhered to the outer periphery of the limb to achieve a leak-proof seal at the assembly position of the inner padding 3. The assembled device is then wrapped around the injured limb with the inner surface of the insulating pad 32 aligned with the swollen area. The upper and lower elastic straps 12 are pulled around the outer periphery of the limb, and the stretch of the elastic straps 12 is adjusted according to the limb's thickness. The corresponding buckles 13 on both sides are then fastened. The elastic straps 12 use their own elasticity to pull the leak-proof protective strap 11 and the inner padding 3 to hug the limb, completing the overall clamping and tightening. The clamping bend 113 has a C-shaped arc structure, which adapts to the cylindrical shape of the limb and will not cause localized hard pressure injuries.

[0040] Example 3, based on Examples 1 and 2, such as Figures 7 to 8 As shown, the inner pad 3 includes a connecting strap 31, and a heat insulation pad 32 is connected to the surface of the connecting strap 31. The surface of the heat insulation pad 32 is arrayed with ventilation holes 33. After the ice application process is completed, press the buckle 13 to release the fastener, untie the elastic strap 12 to remove the entire set of equipment, and directly pull the heat insulation protective component 2 out of the tightening clamp 1. After the ice column 21 is consumed, a brand new pre-cooled heat insulation protective component 2 can be replaced to achieve rapid continuation of ice application. Apply outward pulling force to the inner pad 3, and the connecting strap 31 will disengage from the mounting groove 114, completing the disassembly of the inner pad 3.

[0041] The connecting strip 31 is detachably snapped into the mounting groove 114. The thermal insulation pad 32 is made of EPE pearl cotton. The vent holes 33 are evenly distributed throughout the strip of the thermal insulation pad 32. The connecting strip 31 is a rigid plastic edge strip, and the connecting strip 31 is sewn to the edge of the thermal insulation pad 32. The disassembled inner pad 3 can be cleaned and disinfected separately. The leak-proof protective strip 11 and the thermal insulation protective component 2 can be wiped and disinfected. Each component can be disassembled and processed to adapt to the cyclical use of wounded soldiers in military multi-person training. After all components are cleaned, the inner pad 3 is re-snapped and a new thermal insulation protective component 2 is installed, ready for the next use.

[0042] When in use, the pre-frozen heat insulation protective component 2 is installed into the inner space of the tightening clamp 1, with the heat insulation shell 22 facing outward and the ice column 21 facing inward. Then, the connecting strips 31 on both sides of the inner pad 3 are aligned with the mounting groove 114 on the inner side of the clamping bend 113 of the leak-proof protective strip 11. The strips 111 are pushed into the mounting groove 114 to complete the snap-fit ​​fixation. After assembly, the end face of the ice column 21 is attached to the outer side of the heat insulation pad 32 of the inner pad 3. The cold energy of the ice column 21 is transmitted to the affected area through the heat insulation pad 32 and the vent 33.

[0043] The assembled device is then wrapped around and fitted onto the injured limb with soft tissue damage. The inner surface of the insulating pad 32 of the inner dressing 3 is aligned with the swollen area. The upper and lower sets of elastic straps 12 are pulled around the limb, and the stretch of the elastic straps 12 is adjusted according to the limb's thickness. The buckles 13 on both sides are then fastened accordingly. The elastic straps 12, relying on their own elasticity, pull the leak-proof protective strap 11 and the inner dressing 3 to tightly hold the limb, completing the overall clamping and tightening. The clamping curved plate 113 has a C-shaped arc structure, which adapts to the cylindrical shape of the limb and will not cause localized hard pressure injuries.

[0044] The ice column 21 releases low-temperature cold energy, which passes through the heat insulation layer 32 and the vent 33 and acts on the soft tissue of the affected area. The heat insulation layer 32 forms a buffer layer to prevent the ice column 21 from directly contacting the skin and causing frostbite. The vent 33 ensures a small amount of air circulation on the skin surface and reduces sweating. The outer heat insulation shell 22 isolates the external environment heat from entering the placement cavity 23, reduces the melting speed of the ice column 21, and prolongs the duration of ice application.

[0045] When the icicle 21 melts and produces condensation, the condensation is confined to the inside of the leak-proof protective belt 11. The silicone sealing gasket 112 seals the gap between the connecting belt 31 and the mounting groove 114, preventing the condensation from seeping out and wetting clothing. After the equipment is put on, the injured person can perform small-amplitude limb movements. The elastic strap 12 and the buckle 13 keep the equipment from falling off or shifting.

[0046] After the disassembly, replacement, and cleaning process of ice application is completed, press the buckle 13 to release the fastener, untie the elastic strap 12 to remove the entire set of equipment, and directly pull the heat insulation protective component 2 out of the tightening clamp 1. After the ice column 21 is used up, a brand new pre-cooled heat insulation protective component 2 can be replaced to achieve rapid continuation of ice application. Apply outward pulling force to the inner pad 3, and the connecting strap 31 will disengage from the mounting slot 114, completing the disassembly of the inner pad 3. The disassembled inner pad 3 can be cleaned and disinfected separately, and the leak-proof protective strap 11 and the heat insulation protective component 2 can be wiped and disinfected. Each component can be disassembled and processed to adapt to the cyclical use of wounded soldiers in military multi-person training. After all components are cleaned, the inner pad 3 is re-clamped and a new heat insulation protective component 2 is installed, ready for the next use.
