All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
In the prior art, when the air bag is inflated, an air pump is generally used for directly inflating the air bag with external air, and when the air bag needs to be depressurized, the air in the air bag is directly released to the outside. Although the method can realize the normal function of the air wave pressure therapeutic apparatus, the air filled in the air bag is room temperature air, when the room temperature is low, the temperature of the air bag is low, and the air bag needs to be repeatedly inflated and deflated, so that the temperature inside the air bag is always kept at a low level, and a patient continuously feels uncomfortable cold during the use, which is unfavorable for the treatment of the patient.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an air bag circulation heating device provided by the present application, which includes a first air tank 2, a first air pump 3, a second air pump 4, a heater 5, a controller 1, and a plurality of air bags corresponding to an air inlet valve 6 and an air outlet valve 7;
The air inlet end of the first air storage tank 2 is connected with the air outlet end of the first air pump 3, and the air outlet end of the first air storage tank 2 is respectively connected with the air inlet end of each air inlet valve 6; the air outlet end of each air inlet valve 6 is connected with the air inlet end of the air bag corresponding to the air inlet valve 6;
The air inlet end of the first air pump 3 is respectively connected with the air outlet end of the second air pump 4 and the air outlet end of each air outlet valve 7; the air inlet end of each air outlet valve 7 is connected with the air outlet end of the air bag corresponding to the air outlet valve 7; the air inlet end of the second air pump 4 is connected with the outside; the heater 5 is arranged inside the first air storage tank 2 and is used for heating the internal temperature of the first air storage tank 2;
The control end of a first air pump 3 of the controller 1 is connected with the control end of the first air pump 3, the control end of a second air pump 4 of the controller 1 is connected with the control end of the second air pump 4, the control ends of a plurality of air valves of the controller 1 are respectively connected with the control ends of a plurality of air inlet valves 6 and the control ends of a plurality of air outlet valves 7, the temperature control end of the controller 1 is connected with the control end of a heater 5, and the controller 1 is used for controlling the first air pump 3 and the second air pump 4 to charge air.
In the air wave pressure therapeutic apparatus, a first air storage tank 2 is additionally arranged for storing a certain amount of air, the air volume of the first air storage tank 2 needs to be far greater than the sum of the air volumes of all the air bags, and the maximum air pressure needs to be far greater than the sum of the maximum air pressures of all the air bags, so that each air bag can be conveniently inflated and deflated. The first air pump 3 is used for pumping the air in the air bag into the first air storage tank 2, and simultaneously exhausting the air bag and inflating the first air storage tank 2 is equivalent to being responsible for the air circulation inside the whole air wave pressure therapeutic apparatus. The second air pump 4 is responsible for filling the external air into the first air storage tank 2, and considering that the air bag is continuously in air interaction with the external air in the prior art, the air in the air bag is continuously replaced and is not heated, so that the internal temperature of the air bag is always at a lower level; therefore, the second air pump 4 is only used when the air wave pressure therapeutic apparatus just starts to work, and after the first air storage tank 2 is filled with the air with sufficient volume, the second air pump 4 stops working, and the air interaction between the air wave pressure therapeutic apparatus and the external environment is disconnected. The heater 5 sets up inside first gas holder 2, and at the air wave pressure therapeutic instrument during operation, the heater 5 begins to work according to user's demand, heats inside first gas holder 2 for the inside gas temperature of first gas holder 2 heats to higher level, in order to improve user's comfort level. The air wave pressure therapeutic apparatus is provided with a plurality of air bags, the air inlet and the air outlet of each air bag are respectively provided with a corresponding air valve, the air valves are controlled by the controller 1, and the controller 1 controls different air bags to perform inflation and deflation actions at different times according to the working mode selected by a user on a control page of the air wave pressure therapeutic apparatus.
Specifically, for the first air tank 2, in order to meet the requirement of rapid inflation of the air bags, the capacity of the first air tank 2 needs to be far greater than the capacity of a single air bag, the assumed air wave pressure therapeutic apparatus is provided with X air bags in total, the maximum gas capacity of the single air bag is T, the maximum gas pressure is P, the maximum gas pressure of the first air tank 2 needs to be equal to or greater than p×x, and the maximum gas capacity of the first air tank 2 also needs to be equal to or greater than t×x.
For the second air pump 4, when the air wave pressure therapeutic apparatus just starts to work, the air is continuously inflated to the first air storage tank 2, and when the current air pressure and the current air capacity of the first air storage tank 2 meet the requirements, the air is stopped from being inflated to the first air storage tank 2, so that the air wave pressure therapeutic apparatus is prevented from being damaged due to the overlarge air pressure. During normal operation of the airwave pressure therapeutic apparatus, the second air pump 4 is again activated and inflates the first air tank 2 until the current air pressure and the gas capacity of the first air tank 2 return to the above levels, in consideration of the fact that the air may slowly leak from the passage between the first air tank 2 and the air bag due to poor air tightness of the air passage, and thus the current air pressure of the first air tank 2 or the current gas capacity is detected to be too low.
For each air valve corresponding to the first air pump 3 and the air bag, the air valves are controlled by the controller 1, the controller 1 can determine the inflation and deflation time of each air bag according to the current working mode of the air wave pressure therapeutic apparatus, when a certain air bag needs to be inflated, the air inlet valve 6 of the air bag needing to be inflated is controlled to be opened, and the air inlet valve 6 of the air bag needing not to be inflated is controlled to be closed, and similarly, when a certain air bag needs to be deflated, the air outlet valve 7 of the air bag needing to be deflated is controlled to be opened, and the air outlet valve 7 of the air bag needing not to be deflated is controlled to be closed. When a certain air bag needs to be deflated, in order to accelerate the deflation speed of the air bag, the first air pump 3 can start to work at the moment, and the air in the air bag needing to be deflated is filled back into the first air storage tank 2, so that the circulation of the air in the air wave pressure therapeutic apparatus is realized. As a simple example, assuming a total of A, B, C, D air bags, if the current mode of operation of the airwave pressure therapy device requires that the four air bags be inflated and deflated simultaneously, the controller 1 will control the intake valves 6 of the four air bags to open, and then because the gas pressure inside the first air reservoir 2 is much greater than the gas inside the air bags, the first air reservoir 2 will rapidly inflate each air bag, and when the air bags are inflated with sufficient volume of gas, the controller 1 will control the intake valves 6 to close; then after a period of time, the controller 1 controls the air outlet valves 7 of the four air bags to be opened and controls the first air pump 3 to be opened, at the moment, the first air pump 3 can pump out the internal air of the four air bags, and the air is filled back into the first air storage tank 2 through the air passage of the air wave pressure therapeutic apparatus, so that the purposes of rapidly deflating each air bag and circulating the internal air of the air wave pressure therapeutic apparatus are achieved.
For the heater 5, a target temperature of the heater 5 may be set in advance for the controller 1, and when the air wave pressure therapeutic apparatus starts to operate, the controller 1 continuously controls the heater 5 to heat the internal temperature of the first air tank 2 so that the internal temperature of the first air tank 2 reaches the target temperature; when the inlet valve 6 of the air bag is opened, warm air in the first air tank 2 is charged into the air bag to avoid a decrease in the temperature of the air bag.
In combination, the first air storage tank 2, the first air pump 3, the second air pump 4, the heater 5, the controller 1 and the air inlet valve 6 and the air outlet valve 7 which are in one-to-one correspondence with the plurality of air bags are arranged. The air inlet end of the first air storage tank 2 is connected with the air outlet end of the first air pump 3, and the air outlet end of the first air storage tank 2 is respectively connected with the air inlet end of each air inlet valve 6; the air outlet end of each air inlet valve 6 is connected with the air inlet end of the air bag corresponding to the air inlet valve 6, and the air inlet end of the first air pump 3 is respectively connected with the air outlet end of the second air pump 4 and the air outlet end of each air outlet valve 7; the air inlet end of each air outlet valve 7 is connected with the air outlet end of the air bag corresponding to the air outlet valve 7; the air inlet end of the second air pump 4 is connected with the outside; the heater 5 is provided inside the first air tank 2 for heating the internal temperature of the first air tank 2. The control end of a first air pump 3 of the controller 1 is connected with the control end of the first air pump 3, the control end of a second air pump 4 of the controller 1 is connected with the control end of the second air pump 4, the control ends of a plurality of air valves of the controller 1 are respectively connected with the control ends of a plurality of air inlet valves 6 and the control ends of a plurality of air outlet valves 7, the temperature control end of the controller 1 is connected with the control end of a heater 5, and the controller 1 is used for controlling the first air pump 3 to charge air in an air bag into the first air storage tank 2 and controlling the second air pump 4 to charge air in the first air storage tank 2. The first air pump 3 and the first air storage tank 2 are utilized to form an internal air circulation mode of the air wave pressure therapeutic apparatus, so that external air does not need to be continuously filled into the air bag, and the problem of low air bag temperature caused by frequent air exchange is avoided; meanwhile, the heater 5 is used for heating the gas in the first gas storage tank 2 and filling the gas into the gas bag, so that the temperature of the gas bag can be effectively increased, and discomfort to a patient is avoided.
Based on the above embodiments:
In some embodiments, a first pressure sensor is also included;
The first pressure sensor is arranged in the first air storage tank 2, a first pressure signal end of the first pressure sensor is connected with a first pressure signal end of the controller 1, and the first pressure sensor is used for detecting a first air pressure value in the first air storage tank 2.
Referring to fig. 2, fig. 2 is a schematic structural diagram of another air bag circulation heating device provided by the present application, in order to ensure that the internal air pressure of the first air tank 2 is not too high, in the present application, considering that when the second air pump 4 is controlled to charge the external air into the first air tank 2, if the second air pump 4 is simply controlled to charge the first air tank 2 for a period of time, the second air pump 4 is easily charged with too much air for the reason that the real-time air flow of the second air pump 4 is continuously changed and the control accuracy is not high, so that the air pressure inside the first air tank 2 is too high. When the air pressure of the first air storage tank 2 is too high, because the air pressure difference between the first air storage tank 2 and the air bag is too large, excessive air is easily filled into the air bag, and a strong pressing sense is brought to a patient; therefore, a pressure sensor needs to be arranged in the first air storage tank 2, the pressure sensor continuously detects the pressure value in the first air storage tank 2 when the air wave pressure therapeutic apparatus works and sends the pressure value to the controller 1, when the controller 1 controls the second air pump 4 to charge the first air storage tank 2, the controller finds that the pressure value in the first air storage tank 2 is too large, and then controls the second air pump 4 to stop charging, so that the first air storage tank 2 is prevented from being charged with too much gas, and the internal gas pressure of the first air storage tank 2 is prevented from being too large.
Secondly, considering that the partial air wave therapeutic apparatus has poor air tightness, the internal air may leak through the air pipes everywhere, and thus, when detecting that the air pressure inside the first air tank 2 is lower than a certain value, the controller 1 may control the second air pump 4 to inflate the first air tank 2 again to supplement the air of the leaked portion.
In some embodiments, a temperature sensor is also included;
The temperature sensor is arranged in the first air storage tank 2, a temperature signal end of the temperature sensor is connected with a temperature signal end of the controller 1, and the temperature sensor is used for detecting the internal temperature value of the first air storage tank 2.
In order to avoid the air bag temperature from being too high, the present application considers that when the accuracy of the controller 1 controlling the heater 5 is low, the heater 5 is continuously heated, which may cause the temperature inside the first air tank 2 to be too high. Therefore, referring to fig. 2, fig. 2 is a schematic structural diagram of another air bag circulation heating device provided by the present application, a temperature sensor is further disposed in the first air tank 2, and the temperature sensor continuously detects the temperature in the first air tank 2 and sends the detected temperature to the controller 1 when the controller 1 detects that the temperature in the first air tank 2 is higher than a preset temperature, so that the controller 1 stops controlling the heater 5, thereby avoiding the temperature in the first air tank 2 from being too high, and further avoiding the gas temperature in the air bag from being too high.
In some embodiments, a wind wheel is also included;
the wind wheel is arranged inside the first air storage tank 2.
In order to uniformly heat the gas in the first gas storage tank 2, in the present application, referring to fig. 2, fig. 2 is a schematic structural diagram of another circulation heating device for an air bag provided by the present application, and a wind wheel is further disposed in the first gas storage tank 2. The blade windward side of wind wheel is faced to the inlet end of first gas holder 2, and when second air pump 4 charges for first gas holder 2, the air current of the inlet end department of first gas holder 2 can promote the wind wheel and rotate, and when second air pump 4 stopped charging for first gas holder 2, the wind wheel still can continue to rotate for a period of time along with inertia. The wind wheel rotates and can stir the gas in the first gas storage tank 2, and when the heater 5 heats the gas in the first gas storage tank 2, the wind wheel also rotates due to the pushing effect of rising hot gas, so that the gas in the first gas storage tank 2 is fully stirred, and the purpose of uniform temperature of the gas in the first gas storage tank 2 is realized.
In some embodiments, the heater 5 is a heating wire.
In order to simply heat the gas in the first gas tank 2, the heater 5 used in the present application is a heating wire. The heating wire has high heat efficiency, can stably work in a high-temperature environment, is not easy to overheat, has high safety and reliability, can be heated by controlling the heating wire to be electrified by the controller 1 in actual use, is easy to operate and control, and can be used as the heater 5 well.
In some embodiments, the respective air bags are proportional control valves for the respective inlet valve 6 and outlet valve 7.
In order to flexibly inflate and deflate the air bag, the air inlet valve 6 and the air outlet valve 7 arranged at the air bag are proportional control valves. The proportional control valve is a valve for continuously adjusting the input or output gas flow of the proportional control valve according to the output signal, and compared with the traditional switch valve, the switch valve has only two states (full open and full close), and when the switch valve is used as the air inlet valve 6 and the air outlet valve 7 of the air bag, the gas flow which is instantaneously filled into or discharged out of the air bag can be too large due to the large internal air pressure of the first air storage tank 2. Considering that the partial air wave pressure therapeutic apparatus has poor air tightness, when the gas flow rate is too large, a large amount of gas may leak from the connection of the gas passages, resulting in the heated gas being wasted. Based on this, through the use of the proportional control valve, the gas flow rate of the air bag can be controlled to be filled and discharged, the reliability of the whole air wave pressure therapeutic apparatus is improved, and gas leakage is avoided.
In some embodiments, a refrigeration sheet is also included;
The refrigeration surface of the refrigeration piece is attached to the surface of the first air storage tank 2, the heating surface of the refrigeration piece is in contact with the atmosphere, and the control end of the refrigeration piece is connected with the refrigeration control end of the controller 1.
Considering that when the room temperature is high, if the patient is not in the environment where the patient is located, such as an air conditioner or a fan, the air bag is attached to the skin of the patient, which may cause a hot feeling to the patient. Therefore, a cooling plate is attached to a certain side surface of the first air storage tank 2, the cooling surface of the cooling plate is attached to the side surface of the first air storage tank 2, and the internal temperature of the first air storage tank 2 is reduced through the heat conduction principle, so that the temperature of gas filled into the air bag is reduced, and the heat sensation to a patient is avoided.
In some embodiments, a second air reservoir 8 and a circulation air valve 9 are also included;
The air inlet end of the second air storage tank 8 is respectively connected with the air outlet end of each air outlet valve 7, and the air outlet end of the second air storage tank is connected with the air inlet end of the circulating air valve 9;
The air outlet end of the circulation air valve 9 is respectively connected with the air inlet end of the first air pump 3 and the air outlet end of the second air pump 4;
the control end of the second air storage tank 8 of the controller 1 is connected with the control end of the circulation air valve 9;
Wherein the gas volume of the second gas reservoir 8 is smaller than the gas volume of the first gas reservoir 2.
In order to accelerate the exhaust of the air bag, referring to fig. 2, fig. 2 is a schematic structural diagram of another air bag circulation heating device provided by the present application, and a second air tank 8 is further provided, wherein the second air tank 8 is disposed behind the air outlet valve 7 of the air bag and in front of the first air pump 3. When the air wave pressure therapeutic apparatus works normally, the first air pump 3 will pump the air in the second air storage tank 8 and send the air into the first air storage tank 2, the internal air pressure of the second air storage tank 8 decreases gradually, and the first air pump 3 will pump the second air storage tank 8 into an approximately vacuum environment because the air volume of the second air storage tank 8 is smaller than the air volume of the first air storage tank 2. When the air bag needs to be exhausted after the first air storage tank 2 is inflated into the air bag, the air in the air bag is quickly sucked into the second air storage tank 8 because of the approximate vacuum in the second air storage tank 8, so that the air bag is obviously exhausted.
In some embodiments, a second pressure sensor is also included;
Referring to fig. 2, fig. 2 is a schematic structural diagram of another air bag circulation heating device provided by the present application, wherein a second pressure sensor is disposed inside a second air tank 8, a second pressure signal end of the second pressure sensor is connected to a second pressure signal end of the controller 1, and the second pressure sensor is used for detecting a second air pressure value inside the second air tank 8.
In order to further accelerate the exhaustion of the air bag, in the present application, a pressure sensor is further provided in the second air tank 8, and the second pressure sensor transmits the acquired internal air pressure value of the second air tank 8 to the controller 1 so that the controller 1 detects whether the internal pressure of the second air tank 8 is approximately vacuum. When the internal air pressure of the second air storage tank 8 is higher than a certain value, the controller 1 controls the first air pump 3 to be turned on, so that the internal air of the second air storage tank 8 is filled into the first air storage tank 2, and after the air is filled, the circulation air valve 9 is turned off to ensure that the internal pressure of the second air storage tank 8 is approximately vacuum. By ensuring that the internal pressure of the second air tank 8 is approximately vacuum, when the air outlet valve 7 of the air bag is opened, the air pressure difference between the air bag and the second air tank 8 is ensured to be too large so as to rapidly discharge the air in the air bag.
Referring to fig. 3 in conjunction with the above embodiment, fig. 3 is a schematic diagram of a connection relationship of a controller according to the present application, which can determine an internal air circulation flow of an air wave pressure therapeutic apparatus:
1. When the air wave pressure therapeutic apparatus starts to work, the first air pump 3 will pump the air in the second air storage tank 8 into the first air storage tank 2, so that the second air storage tank 8 is approximately vacuum or reaches a certain negative pressure state.
2. The second air pump 4 is also required to be started to supplement the external air into the first air tank 2, so that the internal air pressure of the first air tank 2 at least reaches N times the rated pressure of the single air bag (specifically, the internal air pressure of the first air tank 2 is determined according to the air volume of the first air tank 2, the air volume of the air bag and the rated pressure of the air bag).
3. The heater 5 is started to heat the gas in the first gas storage tank 2, and after a period of heating, the air inlet valves 6 at different air bags are opened according to the treatment mode selected by the user on the human-computer interface of the air wave treatment instrument, so that the air bags are rapidly inflated.
4. In the process of inflating the air bag, the gas pressure value of the first gas storage tank 2 is monitored in real time, and when the internal gas pressure value of the first gas storage tank 2 is lower than the gas pressure threshold corresponding to the current treatment mode, the inflation valve is closed to avoid excessive gas inflating the air bag. After the pressure of the air bag is kept for a certain time, the air outlet valve 7 corresponding to the air bag is opened, and at the moment, the air in the air bag can be rapidly discharged into the second air storage tank 8 because the second air storage tank 8 is approximately in vacuum.
5. In the process of exhausting the air bag, the gas pressure value of the second air storage tank 8 is detected in real time, when the internal gas pressure value of the second air storage tank 8 is higher than a certain threshold value, the first air pump 3 and the circulating air valve 9 are controlled to be opened again, the gas in the second air storage tank 8 is pumped into the first air storage tank 2 until the second air storage tank 8 returns to a state similar to vacuum, and the circulating air valve 9 and the first air pump 3 are closed.
The application also provides an air wave pressure therapeutic apparatus, which comprises an air wave pressure therapeutic apparatus body and a circulating heating device of the air bag;
The air wave pressure therapeutic apparatus body is connected with the circulating heating device of the air bag.
