[0022] Embodiment 1
[0023] Please refer to the accompanying drawings Figures 1-3 The application provides a connecting device for medical air cushion and inflation pump, comprising a first connecting pipe 1, a first joint 2, a second connecting pipe 3 and a second joint 4, one end of the first connecting pipe 1 is a sharp head, the sharp head of the first connecting pipe 1 is inserted into the air cushion joint 5, the first connecting pipe 1 is connected with the second connecting pipe 3 through the first joint 2, and the second connecting pipe 3 is connected with the air pump pipe 7 of the inflation pump 6 through the second joint 4.
[0024] As shown in Figure 1 and Figure 2 , the air cushion joint 5, the first connecting pipe 1, the first joint 2, the second connecting pipe 3, the second joint 4 and the air pump pipe 7 are connected in sequence, wherein one end of the first connecting pipe 1 is a sharp head, the sharp head of the first connecting pipe 1 is inserted into the air cushion joint 5, which improves the connection efficiency of the device, preferably, the outer diameter of the first connecting pipe 1 is equal to the inner diameter of the air cushion joint 5, and the tight fit between the outer wall of the first connecting pipe 1 and the inner wall of the air cushion joint 5 avoids leakage during inflation, thereby improving the air tightness of the device. Since the diameter of the first connecting pipe 1 is smaller than that of the air cushion joint 5, in order to connect the first connecting pipe 1 with the inflation pump 6, the first connecting pipe 1 is connected with the second connecting pipe 3 through the first joint 2, and the second connecting pipe 3 is connected with the air pump pipe 7 through the second joint 4, thereby realizing the sealed connection between the air cushion bed and the inflation pump 6. The first joint 2 and the second joint 4 not only can connect connecting pipes with different diameters into a continuous whole, but also can facilitate the replacement of damaged parts in the connecting device, thereby improving the practicability of the device. By using the first connecting pipe 1, the first joint 2, the second connecting pipe 3 and the second joint 4 to form the connecting device, the air cushion joint 5 and the inflation pump 6 are connected together, thereby prolonging the service life of the medical air cushion bed with broken joints, and the overall structure is simple and the manufacturing cost is very low, so the device has a wide range of applications. Preferably, the first connecting pipe 1 is obtained by cutting an oxygen pipe at a universal joint of a nasal oxygen pipe, the first joint 2 and the second joint 4 are medical universal joints, and the second connecting pipe 3 is a suction pipe, all of which are common hospital equipment and have low cost, thereby greatly reducing the manufacturing cost of the device.
[0025] Specifically, the first joint 2 is provided with a throat 8 at the connection with the first connecting pipe 1, the first joint 2 is provided with a throat 8 at the connection with the second connecting pipe 3, the second joint 4 is provided with a throat 8 at the connection with the second connecting pipe 3, and the second joint 4 is provided with a throat 8 at the connection with the air pump pipe 7. The first joint 2 and the first connecting pipe 1, the first joint 2 and the second connecting pipe 3, the second joint 4 and the second connecting pipe 3, and the second joint 4 and the air pump pipe 7 are respectively sealed and fixed by the throats 8, so as to avoid leakage during inflation, increase the connection strength, and ensure the overall structural strength during inflation. Preferably, the model of the throat 8 is KG127D2144, the width of the throat 8 is 12.7 mm, and the fastening range of the throat 8 is between 21-44 mm.
[0026] Specifically, the diameter of the first connecting pipe 1 is smaller than the diameter of the second connecting pipe 3. The air pump 6 inflates the first connecting pipe 1 with a smaller diameter through the second connecting pipe 3 with a larger diameter. After the pipeline becomes smaller, the inflation time becomes longer, the sensitivity to the pressure change of the air mattress is higher, and the precise pressure control is more easily achieved. The air mattress is prevented from being over-inflated, and the service life of the air mattress is prolonged.
[0027] Embodiment 2
[0028] Please refer to the accompanying drawings Figures 1-5 The difference between the embodiment and the embodiment 1 is that the first connecting pipe 1 is provided with a sealing element at the connection with the air mattress joint 5. The sealing element includes an outer pipe 9 fixed at the connection of the first connecting pipe 1 and the air mattress joint 5, and a sealing ring 10 fixed on the inner wall of the through hole of the outer pipe 9. The inner wall of the sealing ring 10 tightly abuts the outer wall of the first connecting pipe 1 and the air mattress joint 5. By sleeving the hollow outer pipe 9 at the connection of the first connecting pipe 1 and the air mattress joint 5, and tightly abutting the sealing ring 10 at the through hole of the outer pipe 9 with the outer wall of the first connecting pipe 1 and the air mattress joint 5, the sealing ring 10 generates friction with the first connecting pipe 1 and the air mattress joint 5, which plays a role in fixed connection of the first connecting pipe 1 and the air mattress joint 5, and simultaneously plays a role in sealing at the connection, thereby improving the air tightness of the device.
[0029] Specifically, the sealing ring 10 is made of flexible rubber material. The sealing ring 10 is made of flexible rubber material, which facilitates the air mattress joint 5 and the first connecting pipe 1 to pass through the through hole of the sealing ring 10, and the flexible rubber material can more closely abut the outer wall of the air mattress joint 5 and the first connecting pipe 1, thereby avoiding leakage.
[0030] Specifically, the outer tube 9 is communicated with the exhaust pipe 11, and the exhaust pipe 11 is communicated with the balloon 12 at the gas outlet end. If the air leakage occurs at the connection between the air cushion connector 5 and the first connecting pipe 1, since the outer tube 9 arranged at the connection is sealed, the leaked gas can only enter the balloon 12 through the exhaust port of the outer tube 9, and the balloon 12 is inflated. The device can effectively send an alarm when the air leakage occurs, and the practicability of the device is improved. Preferably, the exhaust port is sealingly connected with the balloon 12.
[0031] Specifically, the outer tube 9 is fixedly installed with a support 13 above the exhaust pipe 11, and the support 13 is provided with a sharp 14 above the gas outlet end of the exhaust pipe 11. By arranging the support 13 above the exhaust pipe 11 and arranging the sharp 14 above the gas outlet end of the exhaust pipe 11 opposite to the support 13, when the device leaks and the balloon 12 is inflated, the balloon 12 is broken when it collides with the sharp 14, a sound is emitted, the medical staff is reminded that the air cushion bed leaks, and the warning effect is achieved.
[0032] The above is only a specific implementation manner of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. The protection scope of the present application should be subject to the protection scope of the claims.
