Description

Technical Field

[0001] This application relates to the field of medical auxiliary equipment technology, and in particular to a multifunctional hot and cold compress therapy device. Background Technology

[0002] A hot and cold compress therapy device is a therapeutic instrument that simultaneously provides heating and cooling functions. It is widely used in the medical and sports fields, primarily to help patients promote blood circulation, relieve pain, and provide hot and cold compresses to sprained areas in athletes. The device consists of a main unit and a water bladder. The main unit contains a water tank and a temperature control module for heating or cooling the water tank. The water bladder is connected to the main unit and communicates with the water tank. When using the device, the user attaches the water bladder to the injured area and then adjusts the temperature control module to heat or cool the water tank as needed, thus providing either hot or cold compresses.

[0003] In related technologies, hot and cold compress therapy devices can only achieve the hot and cold compress function through the temperature control module. If patients have other auxiliary treatment needs, other medical auxiliary equipment is required, which makes the function of hot and cold compress therapy devices relatively simple. Summary of the Invention

[0004] To enhance the functionality of hot and cold compress therapy devices, this application provides a multifunctional hot and cold compress therapy device.

[0005] This application provides a multifunctional hot and cold compress therapy device, which adopts the following technical solution:

[0006] A multifunctional hot and cold compress therapy device includes a therapy body, a hot and cold compress water bag, and a massage air bag. The therapy body is provided with a water bag interface for connecting the hot and cold compress water bag and an air bag interface for connecting the massage air bag. The therapy body is provided with a gas massage driving component that inflates the massage air bag through the air bag interface. The massage air bag is provided with multiple independent massage inflation chambers that correspond to different acupoints. The gas massage driving component can drive each independent massage inflation chamber to inflate or deflate individually.

[0007] Optionally, the gas massage drive assembly includes an atmospheric pump, a gas diversion solenoid valve connected to the atmospheric pump, and a gas diversion pipe installed on the gas diversion solenoid valve. The number of gas diversion pipes is consistent with the number of massage inflation chambers and they are connected in a one-to-one correspondence.

[0008] Optionally, the outer wall of the massage airbag is provided with multiple air nozzles at intervals. The number of air nozzles is consistent with the number of massage inflation chambers and corresponds one-to-one. Each air nozzle is equipped with an air tube. An air inlet plug is installed at the end of the air tube away from the air nozzle. Multiple air tubes are connected to the air inlet plug, and the air inlet plug is connected to the airbag interface.

[0009] Optionally, multiple massage airbags are provided, and an air circuit exchanger capable of controlling the simultaneous air intake and exhaust of multiple massage airbags is installed on the air tube. The air circuit exchanger is located between the air nozzle and the air intake plug.

[0010] Optionally, the therapeutic device body is provided with a water-holding chamber, and the therapeutic device body is provided with a heating module for heating the water in the water-holding chamber, a cooling module for cooling the water in the water-holding chamber, and a water pump for controlling the circulation of water in the water-holding chamber and the hot and cold compress water bag.

[0011] Optionally, the water-holding chamber is provided with a heat-insulating baffle, which divides the water-holding chamber into an interconnected transfer water chamber and a hot and cold water-holding chamber. The volume of the transfer water chamber is larger than the volume of the hot and cold water-holding chamber. The water in the hot and cold compress water bag flows back into the transfer water chamber. The heating module heats the water in the hot and cold water-holding chamber, and the cooling module cools the water in the hot and cold water-holding chamber.

[0012] Optionally, a return port is provided on the wall of the intermediate water chamber, and a return pipe connected to the water pump is inserted into the return port. A diversion pipe is provided on the return pipe, and a spiral pipe is connected to the end of the diversion pipe away from the return pipe. The spiral pipe is located inside the intermediate water chamber and is in communication with the intermediate water chamber.

[0013] Optionally, the intermediate water chamber is provided with a floating block that blocks the return port as the water level rises, and the cavity wall of the intermediate water chamber is provided with a connecting hole that communicates with the hot and cold water chamber, and the connecting hole is located above the return port.

[0014] Optionally, the intermediate water chamber has a mixing port on its wall that communicates with the hot and cold water chamber. The mixing port is located below the return port, and the therapeutic instrument body is provided with an elastic button assembly for blocking or opening the mixing port.

[0015] Optionally, the elastic button assembly includes a baffle plate that is slidably mounted on the wall of the transfer water chamber to block or open the mixing port, a button located outside the treatment device body and driving the baffle plate to slide, and a reset spring that drives the button to reset.

[0016] When a cold compress is needed after a hot compress, press the button, and the low-temperature water in the transfer water chamber will enter the hot and cold water chamber to mix with the hot water and lower the water temperature.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] 1. The therapeutic device, when used with the hot and cold compress water bag, can provide users with hot and cold compress functions. When the user wants a massage, the massage air bag is connected to the therapeutic device through the air bag interface. The gas supplied by the air pump is diverted to one of the gas diversion tubes according to the program settings through the diversion solenoid valve, so that the massage inflation chamber corresponding to the gas diversion tube is filled with gas to achieve compression massage. However, the other massage inflation chambers are not filled with gas at this time, thus realizing cyclic massage of different parts of the body.

[0019] 2. Because the volume of the hot and cold water chamber is smaller than that of the transfer water chamber, the heating or cooling module can heat or cool the water in the hot and cold water chamber more quickly. When switching between hot and cold compresses, pressing the button will allow the water in the transfer water chamber located between the mixing port and the connecting hole to enter the hot and cold water chamber through the mixing port and neutralize the water in the hot and cold water chamber, turning hot water into warm water or cold water into warm water. This makes it easier to switch between hot and cold compresses in a shorter time and reduces the waiting time for patients when switching between hot and cold compresses.

[0020] 3. When switching between hot and cold compresses, after the water in the intermediate water chamber located between the mixing port and the connecting hole enters the hot and cold water chamber through the mixing port, the water temperature in the hot and cold compress water bag is opposite to the switched state (that is, when switching from cold compress to hot compress, the water in the hot and cold compress water bag is initially cold water that has not been circulated, but at this time the heating module will heat the water in the hot and cold water chamber). The water in the hot and cold compress water bag will first enter the intermediate water chamber and mix with the water in the intermediate water chamber. The temperature of the mixed water will become room temperature, and then enter the hot and cold water chamber through the connecting hole. Compared with the case where the water in the hot and cold compress water bag that has not been circulated directly enters the hot and cold water chamber after the hot and cold compress function is switched, the above structure enables the corresponding heating module or cooling module to quickly heat or cool the water in the hot and cold water chamber.

[0021] 4. After switching between hot and cold compress functions, the water in the hot and cold compress water bag that was not fully circulated in the previous function will first enter the transfer water chamber through the return port. At this time, the floating block will rise with the water level until the floating block blocks the return port. Then, the remaining water in the hot and cold compress water bag will enter the spiral tube through the diversion pipe. The spiral tube increases the water flow time, which in turn reduces the water temperature and further reduces the waiting time required when switching between hot and cold compress functions.

[0030] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0031] Example 1: This application discloses a multifunctional hot and cold compress therapy device. (Refer to...) Figure 1 and Figure 2The multifunctional hot and cold compress therapy device includes a main body 1, a hot and cold compress water bag 2, and a massage air bag 3. The outer wall of one side of the main body 1 has a water bag interface 11 and an air bag interface 12. When hot and cold compresses are needed, the connector of the hot and cold compress water bag 2 is inserted into the water bag interface 11, and then the water bag 2 is attached to the area of ​​the body requiring hot or cold compresses. When a massage is needed, the connector of the massage air bag 3 is inserted into the air bag interface 12, and then the massage air bag 3 is attached to the area of ​​the body requiring massage. This increases the functionality of the hot and cold compress therapy device and can meet the needs of different people.

[0032] Combination Figure 1 Reference Figure 2 and Figure 3 The therapeutic device body 1 has a water-holding chamber 13 and an equipment mounting cavity 14 on its top. The water-holding chamber 13 and the equipment mounting cavity 14 are adjacent to each other, with the openings of the water-holding chamber 13 and the equipment mounting cavity 14 spaced apart. The water-holding chamber 13 is used to store water, while the equipment mounting cavity 14 is equipped with a gas massage drive assembly 15 that inflates the massage airbag 3 through the airbag interface 12. The waterbag interface 11 and the airbag interface 12 are located on the outer wall of the equipment mounting cavity 14 on the side opposite to the water-holding chamber 13. The bottom of the therapeutic device body 1 has a groove 16, in which a heating module 17 for heating the water in the water-holding chamber 13 and a cooling module 18 for cooling the water in the water-holding chamber 13 are installed. A bottom plate 161 covers the opening of the groove 16 to block the opening. In addition, a water pump 19 is installed in the equipment mounting cavity 14 to control the circulation of water in the water-holding chamber 13 and the hot and cold compress water bag 2.

[0033] Both the heating module 17 and the cooling module 18 are located at the bottom of the water-filling chamber 13. The heating module 17 can be an electric heating tube or a heating rod. If the heating module 17 is a heating rod, the heating rod needs to be placed inside the water-filling chamber 13. In this embodiment, the heating module 17 is preferably an electric heating tube. The cooling module 18 can be a semiconductor refrigeration chip or a compressor refrigeration assembly (i.e., a refrigeration system composed of a compressor, condenser, expansion valve, and evaporator). In this embodiment, the cooling module 18 is preferably a compressor refrigeration assembly. A battery 191, which supplies power to the heating module 17, the cooling module 18, and the water pump 19, is also installed inside the recess 16. The battery 191 is located at the bottom of the equipment mounting cavity 14.

[0034] The water-filled chamber 13 is provided with an outlet pipe connected to the inlet of the water pump 19 and an inlet pipe connected to the outlet of the water pump 19 on the side near the equipment installation chamber 14. The inlet pipe is located above the outlet pipe, so that the water in the water-filled chamber 13 enters the water pump 19 from the outlet pipe and enters the hot and cold compress water bag 2 under the action of the water pump 19. After that, the water circulated in the hot and cold compress water bag 2 re-enters the water-filled chamber 13 through the inlet pipe.

[0035] Combination Figure 2 Reference Figure 4 and Figure 5 The massage airbag 3 has multiple independent massage inflation chambers arranged internally. The gas massage drive assembly 15 includes an air pump 151, a gas diversion solenoid valve 152, and gas diversion pipes 153. Multiple gas diversion pipes 153 are provided, and the number of gas diversion pipes 153 corresponds one-to-one with the number of massage inflation chambers. Each gas diversion pipe 153 is mounted on the gas diversion solenoid valve 152, which controls whether air is emitted from each pipe. The air pump 151 and the gas diversion solenoid valve 152 are both installed in the device mounting cavity 14. The air pump 151 generates airflow, which is distributed through the gas diversion solenoid valve 152 and discharged from one of the gas diversion pipes 153 to inflate the corresponding massage inflation chamber, causing the massage airbag 3 to compress the user's body or acupoints to achieve a massage effect.

[0036] Since the massage airbag 3 has multiple independent massage inflation chambers inside, multiple air nozzles are spaced apart on the outer wall of the massage airbag 3. The number of air nozzles corresponds to the number of massage inflation chambers. Each air nozzle is equipped with an air tube 31, and an air inlet plug 32 is installed at the end of the air tube 31 opposite to the air nozzle. All air tubes 31 are connected to the air inlet plug 32, and the air inlet plug 32 is connected to the airbag interface 12.

[0037] When it is necessary to massage both legs or both arms simultaneously, two massage airbags 3 are provided. When it is necessary to massage both legs and waist or even other body parts simultaneously, multiple massage airbags 3 are provided. The multiple massage airbags 3 have the same structure but different appearances. The accompanying drawings of this embodiment show the massage airbag 3 located at the leg position as an example.

[0038] Reference Figure 5 When multiple massage airbags 3 are provided, the multiple air tubes 31 on the multiple massage airbags 3 are all connected to an air circuit exchanger 33, which is located between the air nozzle and the air inlet plug 32. During massage, the massage inflation chambers at the same position of the multiple massage airbags 3 will be inflated synchronously through the air circuit exchanger 33, thereby squeezing and massaging.

[0039] To facilitate wearing or securing the massage airbag 3 to the user's body, the massage airbag 3 is equipped with a zipper 34, so that the massage airbag 3 can be better wrapped around the body for massage when in use.

[0040] The implementation principle of a multifunctional pressurized hot and cold compress therapy device according to an embodiment of this application is as follows: The therapy device body 1, together with the hot and cold compress water bag 2, can provide the user with hot and cold compress functions. When the user wants a massage, the massage air bag 3 is connected to the therapy device body 1 through the air bag interface 12. The gas supplied by the air pump 151 is diverted to one of the gas diversion pipes 153 according to the program setting through the diversion solenoid valve, so that the massage inflation chamber corresponding to the gas diversion pipe 153 is filled with gas to achieve compression massage. In this way, through the program control, multiple massage inflation chambers are sequentially filled with gas to achieve a sequential cyclic massage on the user's body or different acupoints.

[0041] Example 2: The difference between this example and Example 1 is that, in combination with... Figure 3 Reference Figure 6 and Figure 7 The water-filling chamber 13 is equipped with a heat-insulating baffle 4, which divides it into an interconnected transfer water chamber 41 and a hot / cold water-filling chamber 42. The hot / cold water-filling chamber 42 is located between the transfer water chamber 41 and the equipment installation chamber 14, allowing hot or cold water to be delivered to the hot / cold compress water bag 2 in a timely manner, reducing water temperature consumption. The volume of the transfer water chamber 41 is larger than that of the hot / cold water-filling chamber 42. The water in the hot / cold compress water bag 2 will first flow back into the transfer water chamber 41, then enter the hot / cold water-filling chamber 42, and finally enter the hot / cold compress water bag 2 through the water pump 19. The heating module 17 and the cooling module 18 are both located at the bottom of the hot / cold water-filling chamber 42. This can shorten the patient's waiting time after switching between hot and cold compresses, facilitating timely auxiliary treatment.

[0042] Combination Figure 2 Reference Figure 6 and Figure 7 Since the hot and cold water chamber 42 is close to the equipment installation chamber 14, the outlet pipe connected to the inlet of the water pump 19 is located on the wall of the hot and cold water chamber 42 near the equipment installation chamber 14. A return port is provided on the wall of the transfer water chamber 41 near the hot and cold water chamber 42 (i.e., the side of the heat insulation baffle 4 near the transfer water chamber 41). A return pipe 411 connected to the outlet of the water bag interface 11 is inserted into the return port, allowing water from the hot and cold compress water bag 2 to enter the transfer water chamber through the return pipe 411.

[0043] A floating block 412 is slidably installed on the wall of the transfer water chamber 41, where a return port is located. The floating block 412 rises or falls with the water level in the transfer water chamber 41. When the floating block 412 moves to the return port, it blocks the return port, preventing water from the hot / cold compress water bag 2 from entering the transfer water chamber 41 through the return port. A guide rail is fixedly installed on the wall of the transfer water chamber 41 to position the direction of movement of the floating block 412. The guide rail extends vertically, and the floating block 412 slides stably in the vertical direction via the guide rail. A limiting top plate is fixedly installed at the position of the guide rail where the return port is located to limit the rise of the floating block 412. When the top of the floating block 412 abuts against the limiting top plate, it blocks the return port.

[0044] Combination Figure 2 Reference Figure 6 and Figure 7 The intermediate water chamber 41 has a reflux port on one side, and a connecting hole 413 is provided to communicate with the hot and cold water chamber 42. The connecting hole 413 is located above the reflux port. When the floating block 412 blocks the reflux port, the water level in the intermediate water chamber 41 continues to rise with the water flow until it rises to the position of the connecting hole 413. At this point, the water in the intermediate water chamber 41 can enter the hot and cold water chamber 42 to be heated or cooled.

[0045] A spiral tube 414 communicating with the intermediate water chamber 41 is fixedly installed at the top of the intermediate water chamber 41. A diversion tube 415 communicating with the return pipe 411 is provided on the return pipe 411, and the other end of the diversion tube 415 is connected to the spiral tube 414. When the floating block 412 blocks the return port, the water in the hot and cold compress water bag 2 will flow into the spiral tube 414 through the diversion tube 415 and finally enter the intermediate water chamber.

[0046] The intermediate water chamber 41 has a return port, and a mixing port 416 is provided on its wall, which communicates with the hot and cold water chamber 42. The mixing port 416 is located below the return port. The main body 1 of the therapeutic instrument is provided with a flexible button assembly 5 for blocking or opening the mixing port 416. When switching between hot and cold compress functions, pressing the flexible button assembly 5 will allow room temperature water between the connecting hole 413 and the mixing port 416 to enter the hot and cold water chamber 42 and mix with the water in the hot and cold water chamber 42, thereby improving the heating or cooling efficiency.

[0047] Reference Figure 6 and Figure 7 The elastic button assembly 5 includes a baffle plate 51, a connecting post 52, a button 53, and a return spring 54. The button 53 is located on the outside of the top of the treatment device body 1. The baffle plate 51 blocks the mixing port 416 and is connected to the button 53 via the connecting post 52. The return spring 54 is used to drive the button 53 to reset. Under normal circumstances (when the button 53 is not pressed), the baffle plate 51 blocks the mixing port 416.

[0048] A directional guide rail is fixedly installed on the wall of the intermediate water chamber 41, and the baffle plate 51 slides directionally on the directional guide rail. One end of the connecting post 52 is threadedly connected to the baffle plate 51; the other end passes through the wall thickness of the top of the treatment device body 1 and is exposed to the outside and threadedly connected to the button 53. The reset spring 54 is sleeved on the protruding part of the connecting post 52, and one end of the reset spring 54 abuts against the top of the treatment device body 1; the other end abuts against the bottom of the button 53. Among them, a limiting plate is fixedly installed on the outer wall of the intermediate water chamber 41 of the connecting post 52. When the baffle plate 51 blocks the mixing port 416, the limiting plate abuts against the top of the intermediate water chamber 41.

[0049] The implementation principle of a multifunctional hot and cold compress therapy device in this application embodiment is as follows: Since the volume of the hot and cold water chamber 42 is smaller than that of the intermediate water chamber, the heating module 17 or the cooling module 18 can heat or cool the water in the hot and cold water chamber 42 more quickly.

[0050] When switching to the cold compress function after hot compress, since the water temperature in the transfer water chamber 41 is lower than the water temperature in the hot and cold water holding chamber 42, pressing button 53 will cause the water in the transfer water chamber located between the mixing port 416 and the connecting hole 413 to enter the hot and cold water holding chamber 42 through the mixing port 416 to neutralize the water in the hot and cold water holding chamber 42, turning the hot water in the hot and cold water holding chamber into warm water, thereby shortening the cooling time of the cooling module 18. At this time, since there is still hot water in the hot and cold compress water bag 2 that has not been circulated, some of the hot water in the hot and cold compress water bag 2 will first enter the transfer water chamber to mix with the water in the transfer water chamber. The temperature of the mixed water will become room temperature, and then the room temperature water will enter the hot and cold water holding chamber 42 through the connecting hole 413 as the water level rises. When the floating block 412 blocks the return port, the remaining water in the hot and cold compress water bag 2 will enter the spiral tube 414 through the diversion pipe 415. The spiral tube 414 increases the water flow time, thereby reducing water temperature and further reducing the waiting time required for switching between hot and cold compresses.

[0051] When switching to the hot compress function after a cold compress, the process is the same as described above, except that cold water is mixed with room temperature water to increase the temperature of the cold water, thereby reducing the heating time.

[0052] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
