Description

Technical Field

[0001] The utility model relates to the technical field of therapeutic instruments, in particular to a cold-heat contrast therapeutic device. Background Art

[0002] When an acute sprain or collision occurs during exercise, it will cause local congestion and edema of the soft tissue. At this time, cold or hot compress therapy can reduce the congestion and edema of the soft tissue. However, for high-intensity professional athletes, cold compress alone may cause irreversible stiffness of muscle tissue and affect athletic ability, so cold and hot compresses need to be used alternately for treatment. Usually, cold and hot compresses are applied with ice packs and hot water bags on the affected area. Not only will cold compresses cause the ice to come into direct contact with the skin, but the temperature of hot compresses cannot be adjusted, which can easily cause secondary frostbite or burns to the patient.

[0023] Example

[0024] Cold compress and hot compress are often used in medical care as auxiliary treatment methods.

[0025] Cold compress: Applying a low-temperature object (the medically effective temperature is usually 5-10°C) to the injured part of the patient's body can cause the blood vessels to contract and reduce blood flow. This can effectively reduce inflammation, inhibit pain nerves and thus reduce pain.

[0026] Hot compress: Applying warm objects (the effective temperature for medical students is usually 38-42°C) to the injured part of the patient's body can dilate blood vessels and speed up blood flow. This can increase the flow of oxygen and essential nutrients to the injured part of the body and speed up recovery and healing.

[0027] By alternating between the two states of cold and hot compresses, hot and cold contrast therapy can produce a "pumping" effect to help expel metabolic waste from body tissues and enhance the delivery of oxygen and nutrients, thereby helping muscle tissue to recover and regenerate, and avoiding muscle tissue stiffness, muscle weakness, etc.

[0028] Usually, cold and hot compresses are chosen by applying ice bags and hot water bags to the affected area. Not only will cold compresses cause the ice to come into direct contact with the skin, but the temperature of hot compresses cannot be adjusted, which can easily cause frostbite and burns to the patient.

[0029] Based on this, see Figure 1 The working principle diagram of the hot and cold contrast therapy device shown and refer to Figure 2 The three-dimensional structural diagram of the cold and heat contrast therapy device shown in the figure, this embodiment proposes a cold and heat contrast therapy device, which includes: a device body 10 and a pad; the device body 10 includes: an inner cavity, an energy storage bin 13, a buffer bin 14, a working bin 15 and a heating component; the energy storage bin, the buffer bin and the working bin are all located in the inner cavity; the buffer bin 14 is fixed on the side wall of the energy storage bin 13, and the buffer bin 14 and the working bin 15 are arranged side by side; the working bin 15 is connected to the pad through a second infusion tube and a liquid reflux tube; the heating component is located in the working bin 15; the storage bin 13 A plurality of filter holes 16 connected to the buffer bin 14 are arranged on the side wall of the energy bin 13 close to the buffer bin 14; a first water pump and a first infusion tube are arranged in the buffer bin 14, one end of the first infusion tube is connected to the first water pump, and the other end of the first infusion tube extends to the top of the working bin 15; the working bin 15 is provided with: a one-way overflow component and a second water pump 19; the one-way overflow component is connected to the energy storage bin 13, and the second water pump 19 is connected to the pad through the second infusion tube; the pad is connected to the working bin 15 through the liquid reflux pipe.

[0030] In this embodiment, both the first infusion tube and the second infusion tube are flexible hoses. A delivery port connected to the outside is provided on the top of the energy storage bin 13, and a device cover 11 is installed on the delivery port. When the device cover 11 is opened, only the energy storage bin 13 is directly exposed to the outside, and a sealing plate is additionally installed on the top of the buffer bin 14 and the working bin 15. The filter hole 16 is provided at the bottom of the buffer bin 14, and the one-way overflow component is provided at the top of the working bin 15.

[0031] It should be noted that due to the presence of the filter hole 16, the energy storage bin 13 and the buffer bin 14 are equivalent to communicating vessels, and the liquid level of the energy storage bin 13 is always consistent with the liquid level of the buffer bin 14. However, the buffer bin 14 and the working bin 15 are independent of each other, and the liquid inside them cannot flow freely. The liquid in the buffer bin 14 can only be transported to the working bin 15 in one direction through the first pump. When pouring room temperature water and ice cubes into the energy storage bin 13, it should be noted that the liquid level in the energy storage bin 13 should be lower than the height of the one-way overflow component. Therefore, a water filling scale line lower than the one-way overflow component is set on the side wall of the energy storage bin 13, and the volume of the energy storage bin 13 needs to be greater than the volume of the working bin 15.

[0032] In particular, a first liquid level monitor linked to the first water pump is provided in the buffer bin 14 , a second liquid level monitor linked to the second water pump 19 is provided in the working bin 15 , and a temperature monitor linked to the heating assembly is also provided in the working bin 15 .

[0033] Specifically, when performing a cold compress, first pour room temperature water and ice cubes into the energy storage bin 13. At this time, the room temperature water and ice cubes are exchanged for heat and become cold water. The cold water flows into the buffer bin 14 through the filter hole 16, and the impurities such as crushed ice in the cold water are isolated outside the buffer bin 14 by the filter hole 16. When the liquid level of the cold water in the buffer bin 14 is higher than the height of the first liquid level monitor, the first liquid level monitor triggers and controls the first pump to start, and the first pump delivers the cold water in the buffer bin 14 to the working bin 15 through the first infusion tube. When the liquid level of the cold water in the working bin 15 is higher than the second liquid level monitor again, the second liquid level monitor is triggered and controls the second pump 19 to start, and the second pump 19 delivers the cold water in the working bin 15 to the pad through the second infusion tube. The pad is in direct contact with human skin, and the cold water in the pad directly performs a cold compress operation on the skin. After absorbing the heat of the skin, the cold water in the pad flows back to the working bin 15 through the liquid reflux tube. The first pump continuously injects cold water into the working chamber 15. The subsequently injected cold water will neutralize the liquid in the pad that absorbs a small amount of skin heat and flows back to the working chamber 15. After neutralization, the liquid in the working chamber 15 will always remain at a low temperature. Therefore, the liquid in the pad that flows back to the working chamber 15 through the liquid return pipe will not change the overall liquid temperature in the working chamber 15. The liquid delivered to the pad by the second pump 19 is still cold water. When the liquid level in the working chamber 15 rises to the height of the one-way overflow component, the excess liquid in the working chamber 15 will be discharged to the energy storage chamber 13 through the one-way overflow component. At this point, the cold compress is completed.

[0034] When performing hot compress, set the starting temperature of the temperature monitor. After turning on the hot compress mode, the temperature monitor monitors the temperature of the liquid in the working chamber 15. When the temperature of the liquid in the working chamber 15 is lower than the set temperature, the temperature monitor controls the heating component to start, and the heating component heats the liquid in the working chamber 15 until the liquid in the working chamber 15 meets the set temperature. At this time, the temperature monitor controls the heating component to stop heating and starts the second water pump 19, and the second water pump 19 delivers hot water to the pad through the second infusion tube. The process of the liquid in the pad flowing back to the energy storage chamber 13 is the same as that of cold compress. Please refer to the above-mentioned cold compress reflux process, so it will not be repeated.

[0035] Among them, see Figure 5As shown in the third cross-sectional view of the cold and hot contrast therapy device, the one-way overflow assembly comprises: a one-way valve and an overflow port 21; the overflow port 21 is arranged at the top of the side wall of the working bin 15 close to the energy storage bin 13; the one-way valve is installed in the overflow port 21, and the overflow port 21 is also connected to the energy storage bin 13.

[0036] In this embodiment, the one-way valve is a conventional reverse water check valve. In order to facilitate the discharge of excess liquid in the working chamber 15 to the energy storage chamber 13, the overflow port 21 is tilted downward toward the side of the energy storage chamber 13 to facilitate the liquid to quickly fall to the energy storage chamber 13 when passing through the overflow port 21.

[0037] See also Figure 3 The first cross-sectional view of the thermal contrast therapy device shown and the Figure 4 In the second cross-sectional view of the cold and hot contrast therapy device shown in the figure, the above-mentioned heating component includes: a box body 18, a circuit board 17, a resistance wire and a hollow heat-conducting plate 20; the box body 18 is installed on the side wall of the working chamber 15, and the hollow heat-conducting plate 20 is fixed to the bottom of the box body 18; the circuit board 17 is located in the box body 18; one end of the resistance wire is located in the hollow heat-conducting plate 20, and the other end extends into the box body 18 and is connected to the circuit board 17.

[0038] Specifically, in addition to the above structure, the heating assembly can also be replaced by a heating rod. Therefore, the specific heating structure of the heating assembly is not limited here.

[0039] In one embodiment, the working chamber 15 further includes: a secondary filter assembly; the secondary filter assembly includes: a frame and a filter; the frame is installed on the side wall of the working chamber 15, and the frame is located below the first infusion tube; the filter is fixed in the frame.

[0040] Specifically, the first pump drains the liquid in the buffer bin 14 downward from the top of the working bin 15 through the first water delivery pipe, and the liquid first passes through the filter screen and then enters the working bin 15 during the falling process. The filter screen will filter the liquid again.

[0041] Furthermore, an interlayer is formed between the equipment body 10 and the inner cavity, and a drainage component is arranged at the bottom of the equipment body 10; the drainage component includes: a first down liquid pipe, a second down liquid pipe, a liquid outlet pipe 22 and a cover body 12; the liquid outlet pipe 22 is installed at the bottom of the equipment body 10, one end of the liquid outlet pipe 22 is connected to the outside, and the other end is connected to the interlayer; one end of the first down liquid pipe is connected to the working bin 15, and the other end extends to the interlayer and is connected to the liquid outlet pipe 22; one end of the second down liquid pipe is connected to the energy storage bin 13, and the other end extends to the interlayer and is connected to the liquid outlet pipe 22; the cover body 12 is sleeved on one end of the liquid outlet pipe 22 connected to the outside, and is threadedly connected to the liquid outlet pipe 22.

[0042] In the embodiment of the utility model, a water blocking member inserted into the liquid outlet pipe 22 is provided on the side of the cover body 12 facing the liquid outlet pipe 22 to enhance the water blocking effect of the cover body 12 on the liquid outlet pipe 22. The first lower liquid pipe and the second lower liquid pipe need to be inserted into the liquid outlet pipe 22.

[0043] Specifically, when it is necessary to drain the liquid in the device body 10, the cover body 12 is rotated to loosen the threads at the cover body 12 and the threads at the liquid outlet pipe 22 until the cover body 12 is separated from the liquid outlet pipe 22. At this time, the liquid in the working chamber 15 flows downward into the first lower liquid pipe due to the action of gravity, and the liquid in the energy storage chamber 13 flows downward into the second lower liquid pipe due to the action of gravity. The liquids in the first lower liquid pipe and the second lower liquid pipe merge in the liquid outlet pipe 22 and are discharged to the outside. In particular, one end of the liquid outlet pipe 22 extending to the outside can be fixedly connected to a lengthened rubber hose, and a plug is provided at one end of the rubber hose away from the liquid outlet pipe 22. When it is necessary to drain the energy storage chamber 13 and the working chamber 15, the drainage direction can be controlled by controlling the direction of the rubber hose.

[0044] Furthermore, the device body 10 is also provided with an air pump and an air delivery pipe connected to the air pump, and the air delivery pipe is a flexible hose; the pad includes: a liquid storage chamber and a pressurizing chamber; the pressurizing chamber is located at the periphery of the liquid storage chamber and an air pressure sensor is provided in the pressurizing chamber; the liquid storage chamber is connected to the working chamber 15 through the second liquid delivery pipe and the liquid return pipe respectively; the pressurizing chamber is connected to the air pump through the air delivery pipe. The pressurizing chamber is provided with an air release hole connected to the outside and a plug that cooperates with the air release hole.

[0045] In the embodiment of the utility model, the pad needs to be attached to the skin to achieve the cold compress and hot compress functions on the skin. Therefore, the two ends of the pad are fixedly connected with straps. The pad is tied to the affected part of the patient that needs cold compress and hot compress through the straps.

[0046] Specifically, the air pump is turned on and injects gas into the pressurized chamber through the air pipe. At this time, due to the restraint of the strap, the gap between the pad and the skin gradually decreases, making the pad fit more closely to the skin, so that the temperature penetrates into the affected area more evenly and enhances the treatment effect.

[0047] Furthermore, the air pump is controlled by an air pressure sensor, which monitors the air pressure in the pressurized chamber. When the air pressure in the pressurized chamber reaches a set value, the air pump stops working. In particular, the set value includes three gear modes: low, medium and high. The low-range air pressure value is 25 mmHg, the medium-range air pressure value is 50 mmHg, and the high-range air pressure value is 75 mmHg. In this embodiment, the default is low.

[0048] In summary, the utility model provides a cold and hot contrast therapy device, by respectively arranging an energy storage bin 13, a buffer bin 14 and a working bin 15 in the device body 10, a filter hole 16 is arranged between the energy storage bin 13 and the buffer bin 14, a first water pump is arranged between the buffer bin 14 and the working bin 15, a heating component is arranged in the working bin 15, and the working bin 15 is connected with the pad through the second water pump 19; compared with the hot water bag and the ice bag for hot and cold compresses in the related art, ice water is directly poured into the energy storage bin 13 during cold compress, and when the ice water enters the working bin 15, the heating component can adjust the temperature of the ice water to avoid muscle damage caused by too low temperature during ice compress; during hot compress, the heating component is used to melt the ice water and accurately control the heating temperature, so that the hot compress temperature is more accurate, and through alternating hot and cold treatment, the cold compress temperature and the hot compress temperature will be maintained in the most scientific temperature range of clinical experiments, and through alternating hot and cold treatment, frostbite or scalds can be avoided.
