Description

Technical Field

[0001] This invention relates to a pressure hot and cold compress machine, belonging to the field of medical auxiliary equipment technology. Background Technology

[0002] In daily life, it is often necessary to use physical methods to cool or warm the affected areas of the body, such as applying cold or hot compresses, to treat local swelling and pain during the acute phase of bone injuries, sprains, contusions, and lacerations within 24 to 48 hours. After the acute phase, hot compresses are used. Cold compresses are needed to quickly reduce swelling and relieve pain after orthopedic or surgical procedures. Cold and hot compresses are usually applied to the patient's skin using towels or water bags. However, the temperature cannot be maintained continuously, and the towels or water bags need to be changed frequently. Furthermore, the temperature is difficult to control, and the temperature of the towels or water bags is inconsistent each time they are used.

[0003] To address the problems associated with hot and cold compress therapy using towels or water bags, Chinese utility model patent CN202051891U discloses an intelligent hot and cold compress system. This system includes a hot and cold compress bag, a water tank, a circulating pump, a thermoelectric cooler, a temperature sensor, and a main control circuit module. The water tank has an openable lid, and the circulating pump is connected to the water tank and the hot and cold compress bag via pipes. The thermoelectric cooler is equipped with a thermoelectric cooling chip, and several transducers are located within the water tank above the thermoelectric cooler. A radiator is located below the thermoelectric cooler. The main control circuit module is electrically connected to the circulating pump, the thermoelectric cooler, and the temperature sensor.

[0004] The hot and cold compress system disclosed in the aforementioned patent has the following defects: First, its pressure is constant and cannot be changed during the hot and cold compress process, leaving considerable room for improvement in treatment effectiveness; second, the patent lacks a structure for observing the water level, requiring the water tank cover to be opened to observe the water level in the storage tank, making it impossible to add water to the storage tank in a timely manner; third, the cooling fan in the aforementioned patent is located at the bottom of the hot and cold compress machine to dissipate the heat generated by the semiconductor cooling chip from the bottom of the casing, but the bottom space of the casing is small and easily obstructed by the work surface supporting the hot and cold compress machine system, resulting in poor heat dissipation; furthermore, since the cooling fan is located outside the casing, it requires relatively tall support feet to support the casing and provide sufficient space for the cooling fan, and the higher the support feet, the worse the overall stability; fourth, the aforementioned patent lacks a built-in power supply, making it unusable in environments without power supply facilities; fifth, the aforementioned patent has a large water tank cover, requiring the water tank cover to be completely removed from the storage tank before water can be added; sixth, its function is relatively limited, as it cannot monitor the patient's vital signs or other physical indicators besides performing hot and cold compresses. Summary of the Invention

[0005] The purpose of this invention is to provide a pressurized hot and cold compress machine that solves the technical defects of existing hot and cold compress machines that perform hot and cold compress treatment on patients under constant pressure, cannot change the pressure during the treatment process, and still have considerable room for improvement in treatment effect.

[0006] To solve the above problems, the technical solution adopted by the present invention is: a pressurized hot and cold compress machine, comprising a chassis assembly, a water tank, N semiconductor air conditioning systems, N water pumps, a controller, and a touch screen display. An installation space is formed within the chassis assembly, and the touch screen display is mounted on the chassis assembly. The water tank, semiconductor air conditioning systems, water pumps, and controller are all installed within the installation space of the chassis assembly. The water tank is used to store water during use. A water inlet is provided on the chassis assembly for filling the water tank. The chassis assembly has N pairs of water inlets and outlets, where N is an integer greater than or equal to 1. Each pair of water inlets and outlets is used to connect the outlet and inlet of an external compress bag via an insulated hose during use. The external compress bag is fixed to the area requiring treatment on the patient during use. Each outlet is connected to the water tank via an inlet pipe within the chassis assembly. A water valve is installed on the inlet pipe. Closing the water valve stops the flow of water in the inlet pipe and adjusts the water pressure inside the outer bag. Each outlet is connected to a semiconductor air conditioning system and the water tank via an outlet pipe within the chassis assembly. The semiconductor air conditioning system is used to adjust the temperature of the water flowing through the outlet pipe. A water pump is installed on the outlet pipe connecting the water tank and the semiconductor air conditioning system. The controller is electrically connected to the semiconductor air conditioning system, the water pump, and the touch screen display. The touch screen display is operated by the controller to control the circulation of water between the water tank, the water pump, the semiconductor air conditioning system, and the outer bag. The semiconductor air conditioning system individually controls the water temperature entering each outer bag, and the water pump individually adjusts the pressure inside each outer bag. This invention allows for adjustment of the water pressure within the outer compressive bag. When the water valve is closed, the water pump pumps water into the bag, increasing the water volume and pressure. Opening the valve allows the water to flow back to the water tank, thus adjusting the water pressure to suit the different needs of patients requiring hot and cold compresses. By increasing and decreasing the intervals of water pressure within the outer compressive bag, this invention provides pulsating pressure during hot and cold compresses, promoting blood circulation and enhancing the therapeutic effect. Furthermore, this invention can connect to multiple compressive bags, allowing for simultaneous hot or cold compresses to multiple patients. Moreover, it allows for tailored treatment of different patients at the same time, addressing their individual needs by providing either hot or cold compresses.

[0007] As a further improvement of the present invention, a blood pressure sensor and a heart rate sensor are provided on the external dressing bag. The chassis assembly includes interfaces for the blood pressure sensor and the heart rate sensor, which are connected to the controller. In use, the sensor cables for the blood pressure sensor and the heart rate sensor are connected to the respective interfaces. The blood pressure sensor detects the patient's blood pressure and displays it on the touchscreen display, while the heart rate sensor detects the patient's heart rate and displays it on the touchscreen display. By incorporating the blood pressure sensor and the heart rate sensor, the present invention can measure the patient's blood pressure and heart rate and display them on the touchscreen display, offering more functionality compared to existing technologies.

[0008] As a further improvement of the present invention, a water level indicator is provided on one side of the chassis, with its bottom end communicating with the bottom of the water tank. This water level indicator has high water level markings, medium water level markings, and low water level markings arranged from top to bottom to indicate the water level in the tank. When the water level indicated on the indicator is between the medium and low water level markings, water is added to the tank through the water inlet. The present invention allows for direct observation of the water level in the tank via the water level indicator. During use, water can be added to the tank promptly as needed, ensuring the safe operation of the invention.

[0009] As a further improvement of the present invention, several heat dissipation holes are provided on both sides of the semiconductor air conditioning system in the chassis assembly, and fans are provided on both sides of the semiconductor air conditioning system inside the chassis assembly. These fans are used to dissipate heat from the semiconductor air conditioning system to the outside of the chassis assembly through the heat dissipation holes. When the semiconductor air conditioning system in the present invention adjusts the water temperature, the heat generated is promptly dissipated from the heat dissipation holes by the fans. The fans in the present invention are located on both sides of the chassis assembly, providing a larger and unobstructed space for hot air to escape from the chassis assembly. Compared with the prior art where the cooling fan is placed at the bottom of the hot and cold compress machine, and the exhausted hot air is blocked by the table supporting the hot and cold compress machine, the present invention facilitates the heat to escape from the chassis assembly more easily, and avoids the need for higher support feet at the bottom of the chassis due to the fans being installed at the bottom. The fans in the present invention are located inside the chassis assembly, which can effectively reduce the space occupied by the present invention and make the overall appearance structure of the present invention more regular.

[0010] As a further improvement of the present invention, a drain valve is installed at the bottom of the chassis assembly. The inlet end of the drain valve is connected to the bottom of the water tank, and the height of the drain valve is less than the height of the bottom of the water tank. The outlet end of the drain valve extends outside the chassis assembly. Opening the drain valve allows water in the water tank to be discharged from the bottom of the chassis assembly. Because the drain valve is lower than the height of the water tank in the chassis assembly, the water in the tank can be completely drained promptly after use, ready for the next use. This is especially important when there are long intervals between uses, as timely drainage prevents water from being stored in the tank for extended periods and becoming contaminated or spoiled.

[0011] As a further improvement of the present invention, a temperature sensor is also included. The temperature sensor is installed on the water outlet pipe between the semiconductor air conditioning system and the water outlet. This temperature sensor is used to detect the water temperature entering the external dressing bag. The temperature sensor is electrically connected to the controller, sending the water temperature information to the controller, which then controls the semiconductor air conditioning system to adjust the water temperature. The present invention uses a temperature sensor to detect the water temperature in the outlet pipe, thereby confirming the water temperature entering the external dressing bag, ensuring the most suitable temperature for the patient. Furthermore, the temperature sensor can continuously monitor the water temperature entering the external dressing bag, providing a basis for the controller to adjust the water temperature by controlling the semiconductor air conditioning system. When the temperature difference between the water temperature and the set temperature exceeds a set value, the water temperature is adjusted, allowing the patient to receive hot and cold compress therapy within the set temperature range.

[0012] As a further improvement of the present invention, a pressure sensor is also included. The pressure sensor is disposed on the external dressing bag and electrically connected to the controller. The pressure sensor is used to detect the pressure of the external dressing bag and send the pressure of the external dressing bag to the controller, which then controls the start and stop of the water pump. The present invention improves the therapeutic effect of hot and cold compresses on the patient by using a pressure sensor on the external dressing bag to detect the pressure of the water inside the bag and supplying water to the bag via a water pump to change the pressure of the external dressing bag on the patient.

[0013] As a further improvement of the present invention, a power supply is also included. The power supply is located within the installation space of the chassis and is connected to and supplies power to the semiconductor air conditioning system, water pump, controller, and touch screen. A power socket is provided on the chassis and is electrically connected to the power supply. In use, the power socket is connected to an indoor power strip via a power cord. By incorporating a built-in power supply within the chassis, the present invention can power its own operation, enabling its use in environments without power supply facilities and thus expanding its applicability.

[0014] As a further improvement of the present invention, a handle is also included, which is disposed on the top of the housing assembly for lifting and moving the pressurized hot and cold compress machine. The present invention provides a handle on the top of the housing assembly, allowing the invention to be moved by lifting it with one hand. Compared to the prior art, which requires both hands to apply force from both sides before lifting and moving, this reduces the need for one hand, thus allowing the present invention to be moved more conveniently as needed.

[0015] As a further improvement of the present invention, it also includes three or more foot pads, which are fixed to the bottom of the chassis assembly and arranged in a non-linear pattern to support the chassis assembly. The foot pads in this invention support the chassis assembly on one hand, and on the other hand, raise the chassis assembly of the present invention, separating it from the support platform supporting the present invention. This prevents water from spilling onto the support platform when water is poured into the water tank, thus avoiding potential electrical leakage that could affect the safe use of the present invention. It also prevents water from adhering to the present invention on the support platform during use, making it easier to lift and move the present invention.

[0016] As a further improvement of the present invention, the water inlet is connected to the water tank inside the chassis assembly via a water inlet pipe, and a cover is provided at the water inlet. The cover is threaded into the water inlet, and unscrewing the cover allows water to be added to the water tank through the water inlet. By connecting the water inlet and the water tank with a water inlet pipe, the present invention ensures that water added through the water inlet flows smoothly into the water tank, effectively preventing water from flowing into parts outside the water tank within the chassis assembly when adding water, thus avoiding damage to the internal components of the chassis assembly. Furthermore, the cover effectively prevents impurities from entering the water tank through the water inlet and prevents water from flowing out of the water inlet.

[0017] In summary, the beneficial effects of this invention are as follows: During use, this invention can maintain a constant temperature, and can also provide hot and cold compresses to patients under normal pressure as needed, or perform pulsating pressurization to improve the therapeutic effect; this invention allows for direct observation of the water level in the tank, facilitating timely replenishment; this invention facilitates heat dissipation during use and has a simpler structure; this invention allows for timely drainage of the water tank after use for future use; and this invention has a wider range of applications compared to existing technologies.

[0026] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0027] like Figures 1 to 7 The pressurized hot and cold compress machine shown includes a chassis assembly 1, a water tank 2, N semiconductor air conditioning systems 3, N water pumps 4, a controller 5, and a touch screen display 6, where N is an integer greater than or equal to 1. In this invention, N is optimally 2. The chassis assembly 1 forms an installation space, and the upper front part of the chassis assembly 1 is tilted. The touch screen display 6 is located on the tilted front part of the chassis assembly 1; therefore, the touch screen display 6 in this invention is also tilted for ease of operation and observation. The water tank 2, semiconductor air conditioning systems 3, water pumps 4, and controller 5 are all installed within the installation space of the chassis assembly 1. Two semiconductor air conditioning systems 3 are stacked vertically, and two water pumps 4 are also stacked vertically. The water tank 2 stores water during use. In this invention... The top of the housing assembly 1 is provided with a water inlet for filling water into the water tank 2 before use. In this invention, the water inlet is connected to the top of the water tank 2 via a water inlet pipe (not shown in the figure) inside the housing assembly 1. A cover 19 is provided at the water inlet of the housing assembly 1. The cover 19 is threaded to the water inlet. Unscrewing the cover 19 allows water to be poured into the water tank 2 from the water inlet. When filling the water tank 2, the cover 19 is unscrewed and a funnel is placed at the water inlet. Water is poured into the water tank 2 through the funnel, which can effectively prevent water from splashing onto other parts of the housing assembly 1 when adding water to the water tank 2. The invention should be in a de-energized state when filling water to prevent leakage caused by water splashing onto the housing assembly 1 or other parts.

[0028] like Figure 1 and Figure 7As shown, the present invention has two pairs of water inlets 7 and water outlets 8 on the chassis assembly 1. Both water inlets 7 and water outlets 8 are located on the front side of the chassis assembly 1, below the touch screen display 6. Each pair of water inlets 7 and water outlets 8 is used to connect the outlet and inlet of an external dressing bag via a heat-insulating hose (not shown in the figure) during use. The external dressing bag is either placed over or pasted onto the area requiring treatment. Each water inlet 7 is connected to the water tank 2 inside the chassis assembly 1 via an inlet pipe (not shown in the figure). A water valve (not shown in the figure) is installed on the inlet pipe. This water valve can be a solenoid valve, electrically connected to the controller 5, to close the water valve. The pump 4 is used to prevent water from flowing from the inlet pipe into the water tank 2, allowing water to enter the outer bag under the action of the pump 4 to adjust the water pressure inside the outer bag. Opening the water valve on the inlet pipe allows water to flow freely in the inlet pipe, thus flowing back into the water tank 2 and reducing the water pressure inside the outer bag. The outlet 8 is connected to the semiconductor air conditioning system 3 and the water tank 2 in sequence by two outlet pipes (not shown in the figure) inside the casing assembly 1. The semiconductor air conditioning system 3 is used to adjust the temperature of the water flowing through the outlet pipe. The pump 4 is installed on the outlet pipe connecting the water tank 2 and the semiconductor air conditioning system 3. The controller 5 is electrically connected to the semiconductor air conditioning system 3, the pump 4, and the touch screen 6. By operating the touch screen 6, the controller 5 controls the operation of the pump 4. Water circulates between water tank 2, water pump 4, semiconductor air conditioning system 3, and external dressing bags. Controller 5 controls the semiconductor air conditioning system 3 to individually control the water temperature entering each external dressing bag, and also controls the water pump 4 to individually adjust the pressure inside each external dressing bag. The controller 5 in this invention is prior art, and will not be described in detail here. This invention includes cooling and heating indicator lights on the chassis assembly 1. During use, the cooling or heating mode is selected on the touch screen 6. When the semiconductor air conditioning system 3 is in cooling mode for cold compress treatment, the cooling indicator light illuminates; when the semiconductor air conditioning system 3 is in heating mode for hot compress treatment, the indicator light illuminates. When the heating indicator light is on, the present invention can select the cooling mode or heating mode and set the working temperature through the touch screen 6 to perform cold or hot compress treatment on the patient. The present invention has a blood pressure sensor (not shown in the figure) and a heart rate sensor (not shown in the figure) on the outer dressing bag. The chassis assembly 1 has a blood pressure sensor interface (not shown in the figure) and a heart rate sensor interface (not shown in the figure) connected to the controller 5. In use, the sensor cables of the blood pressure sensor and the heart rate sensor are connected to the blood pressure sensor interface and the heart rate sensor interface, respectively. The blood pressure sensor is used to detect the patient's blood pressure and display it on the touch screen 6, and the heart rate sensor is used to detect the patient's heart rate and display it on the touch screen 6.

[0029] In this invention, water is cooled or heated to a set temperature by a semiconductor air conditioning system 3, and then pressurized and output by a water pump 4 to an external dressing bag fixed to the patient's affected area. This provides physical cooling or heating to the affected area for cold or hot compress therapy. Cold compress therapy is used for local swelling and pain during the acute phase (24 to 48 hours) caused by bone injuries, sprains, contusions, or lacerations. The cold compress temperature setting range of this invention is 6℃ to 15℃. After the acute phase, hot compress therapy is used. The hot compress temperature setting range of this invention is 38℃ to 50℃. Cold compresses are needed for rapid reduction of swelling and pain after orthopedic or surgical procedures. This invention is particularly suitable for patients with high fever or cold body who require physical cooling or heating.

[0030] like Figure 5 As shown, the present invention has a water level indicator 9 on the left side of the chassis assembly 1, the bottom of which is connected to the bottom of the water tank 2. The water tank 2 is located on the left side of the installation space of the chassis assembly 1. The water level indicator 9 is made of transparent material and has high water level, medium water level and low water level indicators from top to bottom. It is used to indicate the water level in the water tank 2 according to the changes in the water level in the water tank 2. During the use of the present invention, when the water level indicated by the water level indicator 9 is between the medium water level and the low water level, the power should be cut off in time, and water should be added to the water tank 2 through the water inlet. When adding water to the water tank 2, the water level indicated by the water level indicator 9 should be observed while adding water. When the water level reaches between the medium water level and the high water level, the water addition to the water tank 2 should be stopped, and the power should be turned on again for use.

[0031] like Figure 5 and Figure 6 As shown, the present invention provides several heat dissipation holes 10 on both sides of the semiconductor air conditioning system 3 on the chassis assembly 1. The semiconductor air conditioning system 3 is installed on the rear side of the installation space of the chassis assembly 1, so the heat dissipation holes 10 are opened at the rear of the left and right sides of the chassis assembly 1. Inside the chassis assembly 1, a fan 11 is provided on each side of the semiconductor air conditioning system 3. The fan 11 is detachably installed on the chassis assembly 1 with screws. The fan blades of the fan 11 rotate to dissipate the heat generated by the semiconductor air conditioning system 3 through the heat dissipation holes 10 to the outside of the chassis assembly 1 in a timely manner, thereby achieving the function of heat dissipation of the semiconductor air conditioning system 3, avoiding heat accumulation inside the chassis assembly 1, and improving the safety of use. The present invention provides an inspection hole on the rear side of the chassis assembly 1, and a mounting plate 21 is detachably installed on the chassis assembly 1 with screws. The mounting plate 21 closes the inspection hole when in use. The mounting plate 21 can be removed to inspect the semiconductor air conditioning system 3 and the fan 11 inside the chassis assembly 1.

[0032] like Figure 3 , Figure 5 and Figure 7As shown, the present invention has a drain valve 12 installed at the bottom of the installation space of the housing assembly 1. The drain valve 12 is detachably installed on the housing assembly 1 with screws. The water inlet 13 of the drain valve 12 is connected to the bottom of the water tank 2 through a drain pipe (not shown in the figure). The height of the drain valve 12 is less than the height of the bottom of the water tank 2, so that when the drain valve 12 is opened, all the water in the water tank 2 can flow to the drain valve 12. The water outlet 14 of the drain valve 12 extends out of the housing assembly 1. After the patient finishes using the pressurized hot and cold compress machine of the present invention, the drain valve 12 can be opened to drain the water in the water tank 2 from the bottom of the housing assembly 1, so that the water tank 2 is in a waterless state when the present invention is not in use, avoiding the water in the water tank 2 from being contaminated or deteriorating due to long-term disuse. When draining the water in the water tank 2, a hose can be connected to the water outlet 14 of the drain valve 12 to drain the water into a designated container.

[0033] This invention includes a temperature sensor (not shown in the figure), which is installed on the water outlet pipe between the semiconductor air conditioning system 3 and the water outlet 8. The temperature sensor detects the temperature of the water entering the outer bag by detecting the temperature of the water in the water outlet pipe. The temperature sensor in this invention is electrically connected to the controller 5. After detecting the water temperature in the water outlet pipe, the temperature sensor sends the water temperature information to the controller 5, and the controller 5 controls the semiconductor air conditioning system 3 to adjust the water temperature. At the same time, this invention can also directly display the temperature of the water entering the outer bag on the touch screen 6.

[0034] This invention includes a pressure sensor (not shown in the figure) to detect the water pressure inside the external dressing bag placed on the patient's treatment area during use. The pressure sensor is mounted on the external dressing bag and electrically connected to the controller 5. The invention also includes a pressure sensor connector (not shown in the figure) on the housing assembly 1, which is electrically connected to the controller 5. During use, the pressure sensor connection wire on the external dressing bag is connected to the pressure sensor connector on the housing assembly 1. The pressure sensor detects the pressure of the external dressing bag and sends this pressure to the controller 5, which then controls the water pump 4 to start and stop. When the solenoid valve is closed, the water pump 4 operates, filling the external dressing bag with water to increase the pressure inside. The pressure of the external dressing bag in this invention can also be directly displayed on the touch screen 6.

[0035] like Figure 3As shown, the optimal configuration of the present invention includes a power supply 15, which is installed in the installation space of the chassis assembly 1. The power supply 15 is connected to the semiconductor air-conditioning system 3, the water pump 4, the controller 5, and the touch display screen 6, and supplies power to the semiconductor air-conditioning system 3, the water pump 4, the controller 5, and the touch display screen 6. The present invention installs a power switch 20 on the chassis assembly 1. The power switch 20 is connected to the battery by a wire. The semiconductor air-conditioning system 3, the water pump 4, the controller 5, and the touch display screen 6 are connected to the power switch 20 by wires. When the power switch is turned on, the semiconductor air-conditioning system 3, the water pump 4, the controller 5, and the touch display screen 6 are powered on. When the power switch 20 is turned off, the semiconductor air-conditioning system 3, the water pump 4, the controller 5, and the touch display screen 6 are powered off simultaneously. The present invention provides a power socket 16 on the chassis assembly 1. The power socket 16 is connected to the power supply 15 by a wire. In the use state, the power socket 16 is connected to an indoor socket by a power cord to charge the power supply 15. The present invention is provided with a fuse between the power socket 16 and the power supply 15 through a fuse holder to further improve the safety of the present invention during use.

[0036] As Figures 1 to 2 and Figures 4 to 7 shown, the present invention is provided with a handle 17. The handle 17 is in a "U" shape with the opening facing downwards. The bottoms of both ends of the handle 17 are detachably installed on the top of the chassis assembly 1 by screws. Lifting the handle 17 upwards can move the pressure cold and hot compress machine of the present invention.

[0037] As Figures 1 to 2 and Figures 4 to 6 shown, the present invention is provided with more than three feet 18 on the chassis assembly 1. The more than three feet 18 are fixed at the bottom of the chassis assembly 1 and are distributed in a non-linear shape, used to support the chassis assembly 1. The present invention preferably has four feet 18. Two feet 18 are fixed on the left and right respectively at the front and rear of the lower surface of the chassis assembly 1. The four feet 18 are distributed at the four vertices of a rectangle. The feet 18 in the present invention are in the shape of a frustum of a cone with the upper end larger and the lower end smaller, and the feet 18 are detachably installed on the bottom of the chassis assembly 1 by hexagon socket head bolts.

[0038] Parts not specifically described in the above specification are all prior art or can be achieved through prior art. Moreover, the specific implementation cases described in the present invention are only the preferred implementation cases of the present invention, and are not used to limit the scope of implementation of the present invention. That is, equivalent changes and modifications made according to the content of the scope of the present invention patent should all be regarded as the technical scope of the present invention.
