Description

Technical Field

[0001] This utility model relates to the technical field of medical devices, and in particular to the technical field of air mattresses. Background Technology

[0002] Pressure ulcers are a common complication of bedridden patients. To minimize the occurrence of pressure ulcers, the use of air mattresses is a common nursing method. However, ordinary air mattresses on the market can only monitor the pressure of the entire air mattress and lack real-time monitoring of the pressure distribution within the air mattress. When the pressure of the air mattress is insufficient, nurses need to check the pressure of each individual air balloon tube, which is time-consuming and labor-intensive. Adjusting the pressure of each individual air balloon tube is even more time-consuming and labor-intensive, which not only increases the workload of nurses but also reduces patient satisfaction.

[0003] Existing patent CN107019373A discloses an air mattress that can monitor temperature and pressure. It monitors the pressure of the air mattress by setting a monitoring device inside the mattress layer, and automatically adjusts the pressure of the air mattress by a control system connected to the monitoring device. However, since the monitoring device is located inside the mattress layer, it is easily damaged when the air mattress is deflated and stored. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art by proposing an air mattress with single-tube pressure regulation function. This allows the device to monitor the pressure of each airbag tube in real time and automatically adjust the pressure, while the pressure sensing device is not easily damaged.

[0005] To achieve the above objectives, this utility model proposes an air mattress with single-tube pressure regulation function, including a control device, an air mattress, connecting hoses, and a pressure sensing device. The air mattress is composed of several airbag single tubes connected in sequence. Each airbag single tube has a second quick-connect female connector installed at one end, which communicates with the inside of the airbag single tube. The control device consists of a housing, an operation panel, a controller, an air pump, an air delivery pipeline, a fixed pipe, an electric control valve, a pressure sensing device, and a first quick-connect female connector. The controller, air pump, and air delivery pipeline are fixed inside the housing, and an operation panel that cooperates with the controller is embedded in the housing. The air pump is connected to the air delivery pipeline. The gas supply line is connected to several fixed tubes that correspond one-to-one with the single tube of the airbag. An electric control valve and a pressure sensing device are installed on the fixed tube. The electric control valve is located upstream of the pressure sensing device. The electric control valve and the pressure sensing device are located inside the outer shell. The electric control valve and the air pump are controlled by a controller. The pressure sensing device is electrically connected to the controller. A first quick-connect female connector is installed at the end of the fixed tube. The first quick-connect female connector is located outside the outer shell. The corresponding fixed tube and the single tube of the airbag are equipped with a connecting hose. The two ends of the connecting hose are respectively equipped with a first quick-connect male connector and a second quick-connect male connector. The first quick-connect male connector is connected to the first quick-connect female connector, and the second quick-connect male connector is connected to the second quick-connect female connector.

[0006] Preferably, all the second quick-connect females on the air mattress are located on the same side of the air mattress.

[0007] Preferably, the operation panel includes a display screen, a buzzer, selection buttons, setting buttons, confirmation buttons, and adjustment buttons, with each selection button corresponding to a fixed tube.

[0008] Preferably, the first quick-connect female, the first quick-connect male, the connecting hose, the second quick-connect male, and the second quick-connect female are all marked with the same number. The corresponding selection buttons and the fixed tube are marked with the same number, but the number markings on different selection buttons are different.

[0009] Preferably, the airbag tube has an elastic dividing membrane inside, which divides the airbag tube into an upper cavity and a lower cavity. A second quick-connect female connector is connected to the upper cavity, and a third quick-connect female connector is installed on the airbag tube. The third quick-connect female connector is the same as the second quick-connect female connector and is connected to the lower cavity.

[0010] Preferably, when the upper cavity is inflated, the elastic separator membrane is attached to the inner bottom wall of the airbag tube, and when the lower cavity is inflated, the elastic separator membrane is attached to the inner top wall of the airbag tube.

[0011] The beneficial effects of this utility model are as follows: By combining an electronically controlled valve and a pressure sensing device, the pressure inside the single airbag tube can be monitored in real time, and the pressure inside the single airbag tube can be automatically adjusted under the control of the controller, making it more convenient to use; the first quick-connect male and first quick-connect female connectors, and the second quick-connect male and second quick-connect female connectors, allow the connecting hose to easily connect the fixing tube and the single airbag tube; the pressure sensing device is located inside the outer shell, making it less prone to damage; the elastic dividing membrane separates the single airbag tube into an upper cavity and a lower cavity, so that even if the upper end of the single airbag tube is worn through, the single airbag tube can still be inflated and provide support, making it more reliable in use.

[0012] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description

Detailed Implementation

[0018] Example 1:

[0019] See Figure 1The present invention relates to an air mattress with single-tube pressure regulation function, comprising a control device 1, an air mattress 3, a connecting hose 2, and a pressure sensing device 17. The air mattress 3 is composed of several airbag single tubes 30 connected in sequence. Each airbag single tube 30 has a second quick-connect female connector 24 installed at one end, and the second quick-connect female connector 24 is connected to the inside of the airbag single tube 30.

[0020] The control device 1 consists of a housing 10, an operation panel 11, a controller 12, an air pump 13, an air supply line 14, a fixed pipe 15, an electric control valve 16, a pressure sensing device 17, and a first quick-connect female connector 23. The controller 12, the air pump 13, and the air supply line 14 are fixed inside the housing 10. An operation panel 11 that cooperates with the controller 12 is embedded on the housing 10. The control range of the internal pressure of each airbag tube 30 by the controller 12 is set through the operation panel 11.

[0021] The air pump 13 is connected to the air supply line 14. The air supply line 14 is connected to several fixed pipes 15 that correspond one-to-one with the single tubes 30 of the airbag. An electric control valve 16 and a pressure sensing device 17 are installed on the fixed pipes 15. The electric control valve 16 is located upstream of the pressure sensing device 17. The electric control valve 16 and the pressure sensing device 17 are located inside the outer shell 10, so that the electric control valve 16 and the pressure sensing device 17 can be fully protected and avoid being hit or squeezed.

[0022] The electrically controlled valve 16 and the air pump 13 are controlled by the controller 12. The pressure sensing device 17 is electrically connected to the controller 12. In order to ensure the stability of signal transmission, the pressure sensing device 17 and the controller 12 are connected by a wired connection.

[0023] The fixed tube 15 is equipped with a first quick-connect female connector 23 at its end. The first quick-connect female connector 23 is located outside the outer shell 10. The corresponding fixed tube 15 and airbag single tube 30 are equipped with a connecting hose 2. The two ends of the connecting hose 2 are respectively provided with a first quick-connect male connector 21 and a second quick-connect male connector 22. The first quick-connect male connector 21 is connected to the first quick-connect female connector 23, and the second quick-connect male connector 22 is connected to the second quick-connect female connector 24.

[0024] In order to facilitate the installation of the connecting hose 2, all the second quick-connect females 24 on the air mattress 3 are located on the same side of the air mattress 3.

[0025] Before use, the pressure control range of each airbag tube 30 needs to be set via the operation panel 11. During use, the pressure sensing device 17 will feed back the internal pressure of the corresponding airbag tube 30 to the controller 12. If the pressure of a certain airbag tube 30 is lower than the lower pressure limit, the controller 12 will start the air pump 13 and open the corresponding electric control valve 16 after receiving feedback from the pressure sensing device 17. The air pump 13 pressurizes the airbag tube 30. When the pressure reaches the median of the pressure control range, the electric control valve 16 and the air pump 13 will be closed in sequence. If the pressure of a certain airbag tube 30 is higher than the upper pressure limit, the controller 12 will open the corresponding electric control valve 16 after receiving feedback from the pressure sensing device 17. The airbag tube 30 will release pressure through the fixed tube 15. When the pressure reaches the median of the pressure control range, the electric control valve 16 will be closed.

[0026] Example 2:

[0027] See Figure 2 Based on Embodiment 1, the operation screen 11 includes a display screen 110, a buzzer 111, a selection button 112, a setting button 113, a confirmation button 114, and an adjustment button 115, with the selection button 112 corresponding to the fixed tube 15.

[0028] To prevent the connecting hose 2 from being connected to the wrong airbag tube 30, the first quick-connect female connector 23, the first quick-connect male connector 21, the connecting hose 2, the second quick-connect male connector 22, and the second quick-connect female connector 24 between the corresponding fixing tube 15 and the airbag tube 30 are all provided with the same numerical markings. The corresponding selection button 112 and the fixing tube 15 are provided with the same numerical markings, but the numerical markings on different selection buttons 112 are different.

[0029] When it is necessary to set the pressure control range of the single airbag tube 30 connected to a fixed tube 15, first press the corresponding selection button 112, then press the setting button 113, first adjust the lower pressure limit by adjusting the lower pressure limit value using the adjustment button 115 (which includes a button to increase the value and a button to decrease the value), then press the confirm button 114, then adjust the upper pressure limit by adjusting the upper pressure limit value using the adjustment button 115, and then press the confirm button 114 again. At this point, the setting is complete.

[0030] The display screen 110 shows the real-time pressure inside each airbag tube 30. When the pressure of a certain airbag tube 30 is lower than the lower limit and cannot be adjusted to the set range after a period of pressurization, the buzzer 111 will sound an alarm, and the corresponding display value will flash rapidly. In this case, it is generally because there is a large air leak in the airbag tube 30. The pressurization time can be modified by connecting the computer to the controller 12. Otherwise, the factory default setting is used. When the pressurization frequency of a certain airbag tube 30 is higher than a certain frequency, the buzzer 111 will sound an alarm, and the corresponding display value will flash slowly. In this case, it is generally because there is a small air leak in the airbag tube 30. The pressurization frequency can be modified by connecting the computer to the controller 12. Otherwise, the factory default setting is used.

[0031] Example 3:

[0032] See Figure 3 and Figure 4 Based on Embodiment 1 or 2, the airbag single tube 30 is provided with an elastic partition membrane 31 inside, which divides the airbag single tube 30 into an upper cavity 35 located above and a lower cavity 36 located below. The second quick-connect female connector 24 is connected to the upper cavity 35. A third quick-connect female connector 25 is installed on the airbag single tube 30. The third quick-connect female connector 25 is the same as the second quick-connect female connector 24. The third quick-connect female connector 25 is connected to the lower cavity 36.

[0033] When the upper cavity 35 is in an inflated state, the elastic separator 31 is attached to the inner bottom wall of the airbag tube 30, and when the lower cavity 36 is in an inflated state, the elastic separator 31 is attached to the inner top wall of the airbag tube 30.

[0034] During normal use, the connecting hose 2 is connected to the second quick-connect female connector 24 via the second quick-connect male connector 22. When the upper cavity 35 leaks air, if the patient is not suitable for transfer or there is no spare air mattress 3, the second quick-connect male connector 22 and the second quick-connect female connector 24 on the connecting hose 2 can be separated and connected to the third quick-connect female connector 25 to inflate the second cavity 36. At this time, the second cavity 36 can replace the first cavity 35 to support the patient.

[0035] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
