Description

Technical Field

[0001] This utility model relates to the field of medical rehabilitation equipment, and in particular to a portable cold compress therapy device that uses EPP material as the structural shell and is combined with a plastic liner, which is suitable for local cold compress therapy in postoperative rehabilitation, sports injury and other scenarios. Background Technology

[0002] A cold compress therapy device is a medical aid that provides a low-temperature environment to a localized area of ​​the body to relieve pain, suppress inflammation, and promote recovery. A typical cold compress system consists of a main unit, connecting pipes, and a cold compress water bladder. The main unit stores a cold source medium or integrates a cooling module, and a water pump continuously delivers cold water to the water bladder, creating a closed-loop cold compress process on the affected area. Traditional cold compress main units mostly use injection-molded shell structures. While these have advantages in appearance and molding precision, they generally suffer from problems such as large size, heavy weight, weak heat retention, and poor impact resistance, making them inconvenient for portability and home rehabilitation use.

[0003] Utility model patent CN211213814U discloses a cold compress therapy device. This device can be adjusted to different heights via an electric push rod, making it more convenient for medical staff to work and increasing the adaptability of the device. It also reduces the labor intensity of medical staff. After adjustment, the cold compress band is fixed to the injured area of ​​the patient with Velcro. At this time, the switch is turned on to turn on the condenser and water pump, and cold water is sent into the cold compress tube. A water outlet pipe is connected to one end of the cold compress tube, which is connected to a water storage tank to circulate the water. This keeps the water in the cold compress tube at a constant temperature, improves the cold compress effect on the patient, and is beneficial to the patient's recovery.

[0004] While the aforementioned device can be adjusted to different heights via an electric push rod, making it more convenient for medical staff and increasing its adaptability, its overall structure is relatively complex, and its large size and weight result in poor portability and mobility, making it difficult for medical staff to move around easily. Furthermore, the lack of insulation in the water tank accelerates the temperature rise of the cold source medium, reducing its cooling effect and requiring more electrical energy for refrigeration. In addition, the rectangular shape of the aforementioned cold compress band does not match the irregular joint structures of the human body (such as the knee, ankle, and shoulder), making it difficult to achieve effective fit and full coverage, resulting in poor cold compress effect. Therefore, to address the above problems, a cold compress treatment device using an EPP outer shell and a plastic inner liner is proposed. Utility Model Content

[0005] To address the technical problems of poor portability and mobility of the devices in the comparative technologies, the lack of effective heat preservation measures, and the difficulty in achieving a close fit between the cold compress and the human body structure, thus making it difficult to achieve complete coverage, this utility model provides a cold compress treatment device with an EPP shell and a plastic inner liner.

[0006] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0007] A cold compress therapy device employing an EPP outer shell and a plastic inner liner includes a cold compress medium tank with an internal partition plate dividing the tank into a cold source chamber and a working chamber. The cold source chamber contains the cold source medium, and the working chamber contains a water pump. A bifurcated water bladder is connected to the cold compress medium tank in a sealed manner via an insulated tube, and the water pump circulates the cold source medium within the bifurcated water bladder. The cold compress medium tank is composed of an EPP outer shell and a plastic inner liner disposed therein, with the plastic inner liner and the EPP outer shell forming a sealed insulated chamber. The plastic inner liner has bottom and side locking protrusions machined inside for locking and fixing the partition plate.

[0008] In one possible implementation, the bottom of the partition plate has a circulation port on one side and a plurality of filter holes arranged in a rectangular array on the other side. The circulating cold source medium enters the working chamber through the filter holes and is pumped by the water pump to the branched water bag. The cold source medium flowing back returns to the cold source chamber through the circulation port. The partition plate has a pump mounting hole for installing the water pump.

[0009] In one possible implementation, the bifurcated water bladder includes a bifurcated water bladder layer, which is formed by molding two layers of membrane material and a layer of velvet. Both ends of the bifurcated water bladder layer are sealed with water bladder pipes, and a water channel structure is formed on the bifurcated water bladder layer.

[0010] In one possible implementation, the insulation pipe includes two flexible hoses, which are connected in parallel and integrally by an externally fitted insulation layer, wherein the two flexible hoses are respectively and sealed to two water bladder connectors.

[0011] In one possible implementation, the cold compress medium box has a first interface slot, in which a sealed water circulation interface is embedded, the water circulation interface being divided into an outlet and an inlet; the end of the insulation pipe is provided with a quick connector, which is plugged into the water circulation interface; wherein, the outlet of the water circulation interface is sealed to the water pump output port, and the inlet of the water circulation interface is connected to the circulation port.

[0012] In one possible implementation, the cold compress medium box has a second interface slot, in which a sealed power interface is embedded and a power cord for electrical connection is plugged in.

[0013] In one possible implementation, the cold compress medium box is provided with a rotatably connected flip-top cover and a fixedly connected cover plate, wherein the cover plate completely closes the working chamber, the flip-top cover is used to close the cold source chamber, and silicone handles are connected to both sides of the cold compress medium box.

[0014] In summary, this utility model has the following beneficial technical effects:

[0015] The device is mainly composed of three parts: a cold compress medium box, a branched water bladder, and an insulated tube. The cold compress medium box is made of an EPP outer shell and a plastic inner liner. Because EPP material has excellent heat insulation performance, lightweight, high strength and impact resistance, it can significantly improve the portability and durability of the device. Therefore, the above structural design can successfully complete the cold compress treatment while ensuring a simple structure, small size and light weight, meeting the current lightweight requirements and making it easy for users to carry and move.

[0016] Because the plastic inner liner and the EPP outer shell form a sealed heat-insulating cavity, and the EPP outer shell itself has a strong heat insulation effect, the cold compress medium box with the above structure has a good heat insulation effect, which can significantly slow down the rate of temperature rise of the cold source medium, thereby prolonging the effective time of cold compress treatment. Furthermore, when the plastic inner liner or the EPP outer shell is damaged, it can be replaced separately.

[0017] Because the bifurcated water bladder is bifurcated in shape and both bifurcated ends can move independently, it has a variety of wrapping methods. Through this large-area ergonomic structure, it can fit multiple parts such as the knee and ankle, and supports wrapping of the back of the knee, thereby improving the overall fit and coverage of the bifurcated water bladder and enhancing the effect of cold compress therapy.

[0025] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0026] like Figure 1-2 As shown, this embodiment provides a cold compress therapy device with an EPP shell and a plastic inner liner structure, including a cold compress medium tank 1 and a branched water bladder 2, which are connected in a sealed manner by an insulation pipe 3. The cold compress medium tank 1 stores a cold source medium for cooling. The cold source medium is pumped to the branched water bladder 2 and circulated therein to achieve a continuous cold compress effect. When the branched water bladder 2 comes into contact with the human body, it can continuously absorb heat through the flowing cold source medium to achieve a cold compress therapy effect. In addition, silicone handles 13 are connected to both sides of the cold compress medium tank 1.

[0027] Since the device is mainly composed of three parts: a cold compress medium box 1, a branched water bladder 2, and an insulation tube 3, the cold compress medium box 1 is composed of an EPP outer shell 101 and a plastic inner liner 102. Therefore, the above-mentioned structural configuration can successfully complete the cold compress treatment, and the structure is simple, with a small size and light weight, thus meeting the current requirements for lightweighting and making it easy for users to carry and move.

[0028] The cold compress medium box 1 consists of an EPP outer shell 101 and a plastic inner liner 102 disposed therein. The plastic inner liner 102 and the EPP outer shell 101 enclose a sealed, insulated cavity 103. This structural design, combined with the strong thermal insulation effect of the EPP outer shell 101 itself, ensures that the cold compress medium box 1 has good thermal insulation properties, significantly slowing down the rate of temperature rise of the cold source medium, thereby extending the effective time of cold compress therapy. Furthermore, when the plastic inner liner 102 or the EPP outer shell 101 is damaged, it can be replaced individually. Figure 2-3 As shown.

[0029] To distinguish the working space and the cold source filling space within the cold compress medium tank 1, a partition plate 14 is installed inside. The partition plate 14 divides the inner cavity of the cold compress medium tank 1 into a cold source chamber and a working chamber. The cold source chamber contains the cold source medium, and the working chamber is equipped with a water pump. Correspondingly, a bottom locking protrusion 104 and a side locking protrusion 105 are machined into the aforementioned plastic inner liner 102 to lock and fix the partition plate 14. Figure 2-3 As shown, the above technical solution can separate the working space of the water pump from the storage space of the cold source medium, making the overall structure more aesthetically pleasing, neat, and easy to use.

[0030] Corresponding to the aforementioned space separation measures, the cold compress medium box 1 is equipped with a rotatably connected flip-top cover 11 and a fixedly connected cover plate 12. The cover plate 12 completely seals the working chamber, while the flip-top cover 11 seals the cold source chamber. Figure 1-2 As shown.

[0031] Traditional water bladders have poor adaptability and enveloping properties. Therefore, the bifurcated water bladder 2 includes a bifurcated water bladder layer 21, which is formed by hot pressing two layers of membrane material and one layer of fleece through a high-frequency mold. Both ends of the bifurcated water bladder layer 21 are sealed with water bladder connecting pipes 23, which are used to achieve circulation communication with the insulation pipe 3 for the cold source medium. Furthermore, a water channel structure 22 is formed on the bifurcated water bladder layer 21 to guide the cold source medium to flow evenly within the bifurcated water bladder layer 21. Figure 4 As shown.

[0032] The membrane side serves as the treatment surface, directly adhering to the user's affected area, while the velvet side faces outwards, facilitating the secure fixation of the bifurcated water bladder 2 to the target treatment area, such as the knee, ankle, or shoulder, using Velcro elastic straps, thus enhancing wearing comfort and fit stability.

[0033] In practical applications, the bifurcated water bladder 2 has a Y-shaped structure, and the two forks can be independently adjusted to wrap around different parts of the body, improving the coverage and flexibility of cold compress. This allows for a variety of wrapping methods. Through this large-area ergonomic structure, it can fit multiple parts such as the knee and ankle, and supports wrapping the back of the knee, thereby improving the overall fit and coverage of the bifurcated water bladder 2, enhancing the effect of cold compress treatment, and reducing the risk of displacement during exercise.

[0034] In the cold source medium circulation system of this device, a water pump serves as the power source, mounted on the partition plate 14 through the pump mounting hole 142. The insulation pipe 3 forms the circulation loop. A circulation port 141 is located on one side of the bottom of the partition plate 14, and several filter holes 143 arranged in a rectangular array are located on the other side. Furthermore, a first interface groove 151 is provided on the cold compress medium tank 1, in which a sealed water circulation interface 15 is embedded. The water circulation interface 15 has an outlet and an inlet. A quick connector 31 is provided at the end of the insulation pipe 3, which is plugged into the water circulation interface 15. The outlet of the water circulation interface 15 is sealed to the water pump output port, and the inlet of the water circulation interface 15 is connected to the circulation port 141. Figure 3-5 As shown.

[0035] The insulation pipe 3 includes two flexible hoses, which are fixedly connected together by an external insulation layer pipe. The two flexible hoses are respectively sealed to two water bladder pipes 23.

[0036] During operation, the water pump pumps the cold source medium through the outlet of the water circulation interface 15 and the insulation pipe 3 to the branched water bladder 2. The cold source medium flows through the branched water bladder 2 and then flows back through the insulation pipe 3, flows in through the inlet of the water circulation interface 15, and finally returns to the cold source chamber through the circulation port 141 to complete the circulation. When the medium in the cold source chamber flows into the working chamber, it is filtered by the filter hole 143 to remove impurities, which protects the water pump. In addition, the water pump is equipped with a remote control 4, which is used to control the operation of the water pump to meet different usage needs.

[0037] The cold compress medium box 1 has a second interface slot 161, in which a sealed power interface 16 is embedded and a power cord 5 is plugged in. The above technical solution can provide power for the operation of the water pump.

[0038] The working principle and usage process of this utility model:

[0039] When in use, add cold source medium, such as ice water, to the cold source chamber of the cold compress medium tank 1. At this time, some of the cold source medium will enter the working chamber through the filter hole 143. Then, start the water pump to make it work, and pump the cold source medium in the working chamber to the heat preservation tube 3 through the water circulation interface 15. The heat preservation tube 3 sends it into the branched water bag 2. The cold compress treatment is achieved by the cold source medium absorbing heat in contact. After absorbing heat, the temperature of the cold source medium will rise and fall back through the heat preservation tube 3 under pressure, and finally return to the cold source chamber through the circulation port 141 to complete the circulation.

[0040] Before or shortly after the water pump starts, the bifurcated water bag 2 needs to be strapped to the area requiring cold compress treatment. Under the action of the activated water pump, the cold source medium flows and comes into contact with the area of ​​the body requiring cold compress treatment, thus completing the cold compress.

[0041] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
