[0026] like Figure 1 As shown, the utility model provides a medical mattress with inflation and heating functions, including a controller 1 and an integrally formed mattress 2, the mattress 2 is provided with an air inlet 3 and a pressure relief port 4, the air inlet 3 is connected to an air pump 5, the air pump 5 is connected to a gas heating device 6 through a gas transport pipe, the pressure relief port 4 is provided with a pressure relief valve, the pressure relief port is connected to a return air pipe 7, a temperature sensor is provided in the return air pipe 7, a pressure sensor is provided in the mattress 2, the controller 1 is electrically connected to the gas heating device 6, the pressure relief valve, the temperature sensor and the pressure sensor, and when the air pump 5 is inflated, the internal pressure value of the mattress 2 is made greater than a preset fixed value, so that the pressure relief valve continuously releases gas.
[0027] It can be understood that, since the user will achieve heat transfer with the gas in the mattress 2 when lying on the mattress 2, and the heat of the mattress 2 will gradually dissipate, at this time, the temperature of the gas in the mattress 2 detected by the temperature sensor in the return air pipe 7 does not reach the specified warming temperature. At this time, the controller 1 controls the heating device 6 to heat, and allows the air pump 5 to inflate the mattress 2. When the air pump 5 inflates, the internal pressure value of the mattress 2 is greater than the preset fixed value, that is, the pressure relief valve can continuously release gas. This process can maintain the gas temperature in the mattress 2 at a better warming temperature, thereby achieving a better warming effect for the user, and the warming method is changed from the surface covering method to the method of laying flat under the patient to facilitate the doctor's operation.
[0028] It should be noted that when the user lies on the mattress 2, the user squeezes the mattress 2, which increases the pressure of the gas in the mattress 2 on the mattress 2. If the pressure value exceeds the preset pressure value, the controller 1 will control the pressure relief valve to release a certain amount of gas to reduce the pressure of the gas in the mattress 2, ensuring that the mattress 2 remains in a relatively soft state and achieving the best comfort. While reducing the pressure of the gas in the mattress 2, it can prevent the mattress 2 from being damaged due to excessive gas pressure, and can effectively increase the service life of the mattress 2.
[0029] It can be understood that the gas flowing out of the return air pipe 7 can represent the approximate temperature of the gas in the mattress 2. The temperature of the gas in the return air pipe 7 can be used as a reference. The temperature in the return air pipe 7 can be detected by the temperature sensor, that is, the temperature of the gas in the mattress 2 can be roughly determined. At this time, the controller 1 can control the gas heating device 6 to heat the gas according to the detection result of the temperature sensor, so that the gas in the mattress 2 is maintained at an optimal temperature to achieve the best use comfort.
[0030] Preferably, at least two temperature sensors are arranged at the same position in the return air duct 7. It is understandable that the temperature difference of the two temperature sensors at the same position is controlled within a certain error range, the measured data is more accurate, and at the same time, when one of the temperature sensors is damaged, the other one can ensure the detection of the mattress temperature to avoid scalding the patient.
[0031] Preferably, the outer wall of the return air duct 7 is provided with a heat insulation layer, which can prevent the loss of heat in the return air duct 7, avoid a large difference between the temperature in the return air duct 7 and the temperature in the mattress 2, and can more accurately detect the temperature of the mattress, so that the mattress temperature can be controlled more timely within the preset temperature range.
[0032] Furthermore, the gas heating device 6 includes a gas heating box, and the outer wall of the gas heating box is provided with a heat insulation layer. It can be understood that the gas heated by the gas heating device 6 is actually heated in the gas heating box, and the heat insulation effect of the gas heating box directly affects the heating effect of the gas. Therefore, the heat insulation layer located on the outer wall of the gas heating box can effectively prevent the heat loss in the gas heating box, and effectively improve the heating efficiency of the gas heating device 6.
[0033] Furthermore, a plurality of pressure sensors are provided and are evenly distributed inside the mattress 2 .
[0034] It can be understood that when the user lies on the mattress 2, since different parts of the mattress 2 are squeezed to different degrees, the pressure sensors of the present application are evenly distributed inside the mattress 2, and can be used to detect the squeezing of various parts of the mattress 2, that is, the internal pressure of the mattress 2 can be better detected, and the data collected by the multiple pressure sensors can reduce the error caused by the detection of a single pressure sensor, that is, the data collected by the pressure sensor of the present application more accurately reflects the pressure of various parts of the mattress, which is convenient for the controller 1 to control the pressure relief valve so that the mattress 2 can achieve the best comfort.
[0035] It should be noted that, after the preset fixed pressure value is set, the air pump 5 will inflate and maintain 5% higher than the preset fixed pressure value, so as to promote the pressure relief valve to continuously release a portion of gas to detect the temperature through the temperature sensor arranged in the return air pipe 7. When the preset temperature is reached, the controller disconnects the gas heating device, thereby realizing the controllable temperature of the mattress 2.
[0036] Furthermore, the air inlet 3 is provided with a one-way valve, which can prevent the gas inside the mattress 2 from flowing back to the air pump 5 through the air inlet 3, thereby effectively improving the working efficiency of the air pump 5.
[0037] Furthermore, the mattress 2 is oval in shape, which conforms to the shape of the human body, which is convex in the middle and narrow at both ends, ensuring that the heat of the mattress 2 can be maximized to provide heating for the user.
[0038] Furthermore, the mattress 2 is arranged with high sides and low center, which can ensure the uniformity of gas pressure distribution in the mattress 2.
[0039] Furthermore, the material of the mattress 2 is polyester fiber, which is soft and can improve the user's comfort.
[0040] In summary, the medical mattress with inflatable heating function provided by the utility model detects the temperature in the return air pipe, that is, the temperature of the gas in the mattress, through the temperature sensor, and achieves the temperature control function through the controller. Two temperature sensors are arranged at the same position in the return air pipe, which reduces the risk of scalding caused by the failure of measuring the temperature due to damage of a single temperature sensor. The outer wall of the return air pipe is provided with a heat insulation layer, which can prevent the heat loss in the return air pipe, thereby reducing the risk caused by the temperature difference. The one-way valve can prevent the gas inside the mattress from flowing back to the air pump 5 through the air inlet 3. Compared with the prior art, in the technical solution of the utility model, the mattress can be heated by the gas heating device, the temperature is controllable, and the gas is continuously released through the pressure relief valve, so that the gas in the mattress is stably maintained at a better warming temperature, the warming effect is better, and the warming method is changed from the surface covering method to the method of laying flat under the patient's body to facilitate the doctor's operation. And according to the pressure detected by the pressure sensor, the pressure relief valve can be deflated to achieve the best comfort level, and the different requirements of patients of different weights for the comfort level of the mattress can be adjusted by changing the set pressure value.
[0041] The embodiments of the utility model are described above in conjunction with the accompanying drawings, but the utility model is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the enlightenment of the utility model, ordinary technicians in this field can also make many forms without departing from the scope of protection of the utility model and the claims, which all belong to the protection scope of the utility model.
