In addition, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0023] Reference Figures 1-4 This utility model provides an embodiment of a pipe connector with a noise reduction function, comprising a flexible gas supply pipe 3 and quick-connect fittings installed at both ends of the gas supply pipe 3. One end of the gas supply pipe 3 is fitted with a bladder via the quick-connect fitting, and the other end of the gas supply pipe 3 is connected to a noise reduction component via the quick-connect fitting. The noise reduction component connects to a built-in air pump, enabling communication between the built-in air pump and the external gas supply pipe 3. The noise reduction component effectively silences the gas being rapidly pumped into or extracted from the gas supply pipe 3. In this embodiment, the noise reduction component is not directly connected to the air pump; it is connected to the air pump through other pipes and valve assemblies.

[0024] In this embodiment, the gas delivery tube 3 is used to rapidly inflate or deflate the connected bladder, allowing the bladder to compress the limbs through rapid expansion or contraction, thus aiding blood circulation. However, prolonged rapid inflation and deflation of the gas delivery tube 3 can cause it to vibrate and generate noise. This technical solution reduces the impact of rapidly inflating and deflation on the gas delivery tube by installing a sound-absorbing component at one end of the tube 3, and also reduces the noise generated by the gas delivery. This technical solution provides noise reduction and vibration damping for the externally mounted gas delivery tube 3, significantly improving the comfort of wearing the bladder.

[0025] As a further improved embodiment, the quick-connect fitting includes a quick-connect fitting sleeve 31 and a second straight-through fitting 32, wherein a fifth channel 321 is provided through the second straight-through fitting 32.

[0026] The second straight pipe seat 32 and the quick pipe connector sleeve 31 are movably connected. One end of the second straight pipe seat 32 is installed in the gas transmission pipe 3, and the other end of the second straight pipe seat 32 is installed on the silencer. The second straight pipe seat 32 is used to connect to the silencer.

[0027] As a further improved embodiment, the silencing component includes a first straight pipe seat 73 for connecting the second straight pipe seat 32 and a first straight pipe 71 installed at one end of the first straight pipe seat 73, wherein the second straight pipe seat 32 is installed on the first straight pipe seat 73 via a quick pipe fitting sleeve 31, and the end of the second straight pipe seat 32 is inserted into the first straight pipe seat 73.

[0028] The first through-tube seat 73 has a third channel 731 and a fourth channel 732 at its two ends, respectively. The diameter of the third channel 731 is not less than the diameter of the fourth channel 732. In this embodiment, the diameter of the third channel 731 is greater than the diameter of the fifth channel 321, and the diameter of the fourth channel 732 is equal to the diameter of the third channel 731. Alternatively, the diameter of the fourth channel 732 is less than the diameter of the third channel 731, and the size of the third channel 731 is equal to the size of the fifth channel 321.

[0029] The first straight tube 71 is provided with a first channel 711 and a second channel 712 at its two ends, wherein the diameter of the second channel 712 is not less than the diameter of the first channel 711.

[0030] One end of the first through pipe seat 73 is installed in the first channel 711.

[0031] In this embodiment, the gas output to the first through-tube 71 passes sequentially through the fifth channel 321, the third channel 731, the fourth channel 732, the first channel 711, and the second channel 712, so that the discharged gas gradually passes through the large-size channel for depressurization and is quickly discharged from the bag. Conversely, the gas output to the gas delivery pipe 3 gradually bulges from the large-size channel to the small-size channel, and then passes through the third channel 731 for transition processing, reducing the noise generated by the first through-tube 71 bulging into the gas delivery pipe 3 and increasing the bag expansion.

[0032] As a further improved embodiment, the diameter of the fourth channel 732 is smaller than the diameter of the third channel 731, and the size of the third channel 731 is equal to the size of the fifth channel 321. In this embodiment, the third channel 731 serves as a transition channel for the gas conveying of the silencer, and the conveyed gas is noise-reducing by increasing the diameter between the fifth channel 321 and the fourth channel 732. The silencer has a noise-reducing function by setting the fifth channel 321, the third channel 731, the fourth channel 732, the first channel 711, and the second channel 712 with different diameters between the gas delivery pipe 3 and the first straight pipe 71, thereby reducing the impact force of the pulsed gas on the gas delivery pipe 3 and also reducing the noise between the gas delivery pipe 3 and the first straight pipe 71.

[0033] As a further improved embodiment, the silencing component also includes a second straight pipe 72 abutting against the other end of the first straight pipe 71. The first straight pipe 71 and the second straight pipe 72 are the same in size and shape, that is, the two ends of the second straight pipe 72 are also provided with a first channel 711 and a second channel 712, wherein the second channel 712 of the first straight pipe 71 is directly connected to the second channel 712 of the second straight pipe 72.

[0034] A straight connecting pipe 9 is connected between the first straight pipe 71 and the second straight pipe 72. In this embodiment, the installation of the straight connecting pipe 9 between the first straight pipe 71 and the second straight pipe 72 further reduces the noise of the transported gas and improves the sealing performance of the first straight pipe 71 and the second straight pipe 72.

[0035] As a further improved embodiment, the silencing component also includes a quick connector straight pipe 8 installed at one end of the second straight pipe 72, wherein the quick connector straight pipe 8 and the first straight pipe 71 are respectively located at both ends of the second straight pipe 72;

[0036] The quick connector straight-through 8 is inserted into the second straight-through pipe 72. The quick connector straight-through 8 has an integrated annular protrusion 81 inside. The annular protrusion 81 is used to further improve the noise reduction effect of the noise reduction component and at the same time enable the noise reduction component to have a quick connection function.

[0037] As a further improved embodiment, the outer surface of the first through pipe seat 73 is equipped with a first arc-shaped clamping plate 51 and a second arc-shaped clamping plate 52. The first through pipe seat 73 is clamped by fixing the first arc-shaped clamping plate 51 and the second arc-shaped clamping plate 52 together. The first arc-shaped clamping plate 51 and the second arc-shaped clamping plate 52 are fixed on the bed body 1, and the first arc-shaped clamping plate 51 and the second arc-shaped clamping plate 52 are installed inside the bed body 1.

[0038] The bed body 1 is provided with air supply pipes 3 on both sides, and a bed board 11 is provided at the upper end of the bed body 1. The bags are placed on the bed board 11, and the bags include an upper limb bag 22 and a hip bag 21.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
