[0036] Example 1

[0037] Reference Figures 1 to 6 This embodiment is an optional embodiment of the present application, which discloses an enema device, including an enema tube 1 and a stoma 2. The stoma 2 body has the same structure as the stoma 2 in the prior art, and an enema port 3 coaxial with the stoma 2 is provided at its center. At the same time, a first connecting tube 4 and a second connecting tube 8 are provided on one end surface of the stoma 2. The first connecting tube 4, the enema port 3 and the second connecting tube 8 are coaxially arranged. The inner diameter of the first connecting tube 4 is 1.5-2 times the outer diameter of the second connecting tube 8, and the inner wall of the second connecting tube 8 is flush with the inner wall of the enema port 3; the area between the first connecting tube 4 and the second connecting tube 8 is the buffer cavity 5;

[0038] Furthermore, a flexible sealing cover 6 is also provided on the enema tube 1, and the flexible sealing cover 6 includes a connecting piece 601, a bellows 602 and a connector 18 connected in sequence, the connecting piece 601 is in a circular ring structure, the outer edge of the connecting piece 601 is integrally connected to one end of the bellows 602, and the other end of the bellows 602 is integrally connected to the connector 18; the connecting piece 601, the bellows 602 and the connector 18 are made of silicone or rubber;

[0039] A fixing groove 19 in an annular structure is also provided on the outer peripheral surface of the first connecting pipe 4, and a fastening tie 20 is also provided on the connecting head 18, and the fastening tie 20 fastens part of the connecting head 18 into the sealing groove;

[0040] During use, the sealing cover and the first connecting pipe 4 can be quickly and tightly connected by fastening the cable tie 20. At the same time, the cable tie 20 is recessed with the fixing groove 19. Therefore, the fastening cable tie 20 squeezes part of the connector 18 into the fixing groove 19 when it is firmly tied, thereby forming a U-shaped sealed gap in the fixing groove 19, which effectively improves the airtightness. After use, the device can be disassembled by simply cutting the fastening cable tie 20, which is convenient to use.

[0041] Secondly, the setting of the bellows 602 can give the flexible sealing cover 6 good elasticity in the axial direction, which is beneficial to reducing the difficulty of operating the flexible sealing cover 6; at the same time, the setting of the bellows 602 can also effectively improve the structural strength of the entire flexible sealing cover 6, avoiding its rupture during frequent reciprocating compression and folding, thereby increasing the service life of the equipment.

[0042] Furthermore, a vent pipe 7 is provided on the connecting piece 601, and the vent pipe 7 is communicated with the external atmosphere. At the same time, a plugging head 701 is threadedly connected to the inlet end of the vent pipe 7, and a plurality of flexible plugging pieces 702 are provided in the plugging head 701. The flexible plugging pieces 702 are radially arranged around the axis of the plugging head 701, and one end of each flexible plugging piece 702 is respectively connected to the plugging head 701, and the free ends thereof overlap each other;

[0043] The plugging head 701 can be used to adjust the on-off state of the vent pipe 7. In actual use, in the compressed state, the air pressure in the buffer cavity increases, thereby pushing each flexible plugging piece 702 to expand outward, thereby connecting to the external environment and reducing the air pressure. On the contrary, the air pressure in the buffer cavity decreases, and the external atmosphere pushes each flexible plugging piece 702 to expand inward, thereby connecting the atmosphere and the buffer cavity. That is, the air pressure in the buffer cavity 5 is adjusted by the vent pipe 7 to avoid air pressure imbalance, and at the same time, a large number of leakage points on the flexible sealing cover 6 can be avoided.

[0044] Furthermore, a folded bellows 602 is inserted into the ventilation tube 7, and an adjusting plug is provided at the free end of the metal tube. Compared with the ventilation tube 7 made of rubber or silicone, the folded bellows 602 has flexibility and better shape retention ability. Therefore, it can be folded arbitrarily according to needs to adjust the position of the pipeline, thereby ensuring that the exhaust port of the ventilation tube 7 is always higher than the enema port 3 to avoid backflow and leakage of enema liquid.

[0045] Furthermore, an adsorption module is also provided in the buffer chamber 5, and the adsorption module includes a shell 9 and a sealing cover 10. The shell 9 is annular in structure as a whole, and its top is completely open and sealed by the sealing cover 10. A plurality of liquid seepage holes 14 are also provided on the shell 9 and the sealing cover 10, and in particular, a plurality of liquid seepage holes 14 are provided on the inner circumferential surface of the shell 9; the shell 9 is also filled with an adsorbent 13, and it should be noted that the adsorbent 13 is a polymer water-absorbing resin, such as a water-absorbing agent used for diapers;

[0046] The bottom surface of the housing 9 is also provided with a threaded tube 11 coaxial therewith, and the outer circumferential surface of the second connecting tube 8 is provided with a connecting thread, and the threaded tube 11 is connected to the second connecting tube 8 through a connecting thread thread; at the same time, a sealing groove is also provided on the inner circumferential surface of the housing 9, and a sealing ring 12 is embedded in the sealing groove;

[0047] The threaded connection can ensure that the adsorption module and the second connecting tube 8 are stably and reliably connected together, especially when the enema tube 1 slides back and forth, the adsorption module can still be stable, thereby ensuring the stability of the entire structure;

[0048] Secondly, the sealing ring 12 can also achieve a sealing of the exudate gap, and the adsorbent 13 can completely absorb the leaked exudate, thereby avoiding the accumulation of a large amount of enema liquid in the buffer chamber 5, thereby minimizing the risk of enema liquid leakage through the technical means of combining physical blocking with active adsorption.

[0049] Furthermore, a guide groove 15 of an annular structure is provided on the inner circumferential surface of the shell 9; a guide cotton ring 16 coaxial with the shell 9 is also sleeved inside the shell 9, and along the axial direction of the shell 9, the inner surface of the guide cotton ring 16 passes through the guide groove 15 and fits with the enema tube 1, and the outer surface of the guide cotton ring 16 fits with the adsorbent 13;

[0050] In the above structure, the guiding cotton ring 16 is completely in contact with the outer wall of the enema tube 1. During the reciprocating motion of the enema tube 1 in the axial direction, the enema liquid contaminated on the surface thereof will be quickly absorbed by the guiding cotton ring 16. At the same time, the good water permeability of the guiding cotton ring 16 guides the enema liquid to quickly contact with the adsorbent 13, thereby reducing the absorption of the enema liquid at the first time when leakage occurs, and avoiding a large amount of leakage liquid from being infused into the buffer chamber 5.

[0051] Further, the guide cotton ring 16 completely fills the internal cavity of the entire shell 9, and at the same time, the inner ring surface of the guide cotton ring 16 passes through the guide groove 15 and is slidably sleeved with the enema tube 1, and at the same time, along the axial direction of the guide cotton ring 16, a plurality of layers of filling cavities 17 are arranged on the guide surface ring, each of which is arranged in an annular structure, and along the radial direction of the guide cotton ring 16, each of which penetrates the outer ring surface of the guide cotton ring 16; it should be pointed out that the number of the filling cavities 17 is determined according to actual conditions;

[0052] When in use, the guide cotton ring 16 is filled into the housing 9, and at the same time, the adsorbent 13 is filled into each filling cavity 17 respectively;

[0053] In the above-mentioned guide cotton ring 16, multiple layers of isolation cotton are arranged along its axial direction, so that the leaked enema liquid can be quickly guided to different areas along the radial direction of the guide cotton ring 16 and contact with the adsorbent 13, thereby shortening the contact time between the adsorbent 13 and the enema liquid as much as possible, improving the adsorption efficiency, and then improving the adsorption effect.

[0054] When the enema device of the present application is used, the stoma is installed on the human body, then the assembled adsorption module is connected to the second connecting tube, and then the outlet end of the enema tube is inserted into the human body through the adsorption module and the enema port, and finally the flexible sealing cover is connected to the first connecting tube;

[0055] During the adjustment process, the ventilation tube is opened, and then the enema tube is pulled back and forth in the axial direction to adjust its position. During the adjustment process, the movement of the enema tube will drive the flexible sealing cover to be compressed or extended synchronously, thereby ensuring the airtightness of the buffer chamber;

[0056] At the same time, the enema liquid that leaks during the enema process is directly absorbed by the adsorption module, thereby controlling the flow of the enema liquid to the maximum extent and avoiding leakage;

[0057] Secondly, compared with the prior art, the present application can achieve sealing of the stoma through a flexible sealing cover while ensuring the sliding adjustment function of the enema tube, thereby reducing the equipment cost and the difficulty of adjusting the equipment.

[0058] The above are only preferred embodiments of the present application, and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
