[0054] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0055] The following description, in conjunction with the accompanying drawings, describes an embodiment of the present invention: an anal tube drainage bottle and a pipe connector.

[0056] like Figures 1-11 As shown, the pipe joint of this utility model embodiment includes a male pipe joint 1 and a female pipe joint 7 that are mutually adapted to each other.

[0057] The male pipe connector 1 includes a holding block 101, an outlet pipe 102, an inner pipe 109, a ring clamping member 106, and a groove 103. The inner pipe 109 is sleeved and fixed to the inner side of the holding block 101, and one end of the inner pipe 109 is connected to the outlet pipe 102.

[0058] The ring clamp 106 is movably sleeved on the outside of the inner tube 109;

[0059] Multiple card slots 103 are opened around the outer periphery of the holding block 101;

[0060] The female connector 7 includes an outer ring 701, a connector 703, and a retaining block 702. The connector 703 is a tubular structure with an internal channel for the inner tube 109 to be inserted.

[0061] The outer ring 701 is sleeved and fixed to the outer peripheral wall of the connector 703, and a space for accommodating the holding block 101 is formed between the inner side wall of the outer ring 701 and the outer peripheral wall of the connector 703.

[0062] The locking block 702 protrudes from the inner side wall of the outer ring 701. The number, shape and position of the locking blocks 702 are adapted to the locking slot 103 one by one, and can form a separable locking engagement with the locking slot 103.

[0063] Specifically, during the connection, the inner tube 109 of the male connector 1 is aligned with the channel of the female connector 7 connector 703 and inserted, and the holding block 101 enters the receiving space between the outer ring 701 and the connector 703 simultaneously with the inner tube 109.

[0064] During insertion, the locking block 702 on the inner sidewall of the outer ring 701 slides along the outer periphery of the holding block 101 until it aligns with the locking groove 103 on the outer periphery of the holding block 101. The locking block 702 is embedded into the locking groove 103 under its own elasticity or assembly force, forming a locking and docking.

[0065] At this time, the ring clamp 106 moves along the outer side of the inner tube 109 toward the holding block 101 under the action of the insertion force, forming a pre-tightening on the snap-fit ​​part.

[0066] When separating, the ring pressing member 106 is pushed towards the holding block 101. The ring pressing member 106 squeezes the locking block 702, causing it to undergo elastic deformation and disengage from the locking groove 103, thus releasing the lock.

[0067] Then, pull the male connector 1 in the opposite direction, and the inner tube 109 is pulled out from the channel of the connector 703. The holding block 101 exits the space between the outer ring 701 and the connector 703, completing the separation.

[0068] In one embodiment of this utility model, such as Figure 2 , Figure 7 As shown, the inner diameter of the channel of connector 703 is clearance-fitted with the outer diameter of inner tube 109, and a tapered guide section is provided at the channel entrance.

[0069] During the pipe joint connection process, the tapered guide section at the inlet of the connector 703 first plays a role: when the inner tube 109 is inserted into the channel of the connector 703, the tapered guide section corrects the centripetal deviation through the tapered inner wall, guiding the end of the inner tube 109 to be precisely aligned with the channel axis.

[0070] As the inner tube 109 is continuously inserted, the clearance fit between the inner diameter of the channel and the outer diameter of the inner tube 109 begins to take effect, ensuring a smooth insertion process and guaranteeing that the inner tube 109 and the connector 703 remain coaxial at all times.

[0071] In one embodiment of this utility model, such as Figures 4-5As shown, the male pipe connector 1 also includes a tension spring 107, which is sleeved on the outside of the inner pipe 109, and the two ends of the tension spring 107 are respectively connected to the holding block 101 and the ring pressing member 106.

[0072] The locking block 702 is an elastic protrusion with a guide slope on one side facing the insertion direction of the male pipe connector 1 and a vertical stop surface on the other side. The locking groove 103 is a groove that fits the locking block 702. When the male pipe connector 1 is inserted into the female pipe connector 7, the locking block 702 slides into the locking groove 103 along the guide slope and is locked by abutting against the side wall of the locking groove 103 through the vertical stop surface.

[0073] Specifically, during docking, as the inner tube 109 is inserted into the channel of the connector 703, the ring pressing member 106 is pushed by external force to move towards the holding block 101, at which time the tension spring 107 sleeved on the outside of the inner tube 109 is compressed.

[0074] The tension spring 107 transmits the force to the ring clamp 106, forming a continuous reverse thrust that causes the ring clamp 106 to tightly press against the engagement part of the locking block 702 and the locking groove 103.

[0075] During separation, when the external force pushes the ring pressing member 106 to release the locking block 702 and the slot 103, the external force is removed, the tension spring 107 releases the stored elastic potential energy, and pushes the ring pressing member 106 to reset along the outside of the inner tube 109 in a direction away from the holding block 101, returning to the initial position, and preparing for the next docking.

[0076] In one embodiment of this utility model, such as Figures 3-7 As shown, the male pipe connector 1 also includes a sealing ring 108, which is sleeved and fixed to the outside of the free end of the inner pipe 109.

[0077] The female connector 7 also includes an adapter groove 704, which is formed on the inner wall of the connector 703 and is adapted to the sealing ring 108.

[0078] During the pipe joint connection process, the sealing ring 108 and the adapter groove 704 cooperate to achieve the sealing function:

[0079] As the inner tube 109 is inserted into the channel of the connector 703 and gradually reaches its final position, the sealing ring 108, fitted onto the outside of the free end of the inner tube 109, moves synchronously with the inner tube 109 and eventually embeds itself into the fitting groove 704 on the inner wall of the connector 703. Due to the fit between the two shapes, the sealing ring 108 undergoes elastic deformation under radial compression within the groove. Its outer circumferential surface fits tightly against the inner wall of the fitting groove 704, and its inner circumferential surface fits tightly against the outer wall of the inner tube 109, forming a double seal that blocks the path of fluid leakage from the gap between the inner tube 109 and the connector 703.

[0080] When the male pipe connector 1 and the female pipe connector 7 are locked together by the locking block 702 and the locking groove 103, the compression state of the sealing ring 108 in the adapter groove 704 remains stable, ensuring a continuous and reliable sealing effect.

[0081] In one embodiment of this utility model, such as Figures 3-7 As shown, the male pipe connector 1 also includes multiple sets of alignment posts 104. The alignment posts 104 are asymmetrically spaced along the outer peripheral wall of the holding block 101 and are circumferentially offset from the slot 103.

[0082] The female connector 7 also includes multiple sets of alignment grooves 705, which are opened on the inner side wall of the outer ring 701. Their number, distribution position and extension direction are adapted to the alignment column 104.

[0083] When the inner tube 109 is inserted into the connector 703 channel, the alignment post 104 can be inserted into the alignment slot 705 to achieve a unique angle connection.

[0084] During the pipe joint connection process, the alignment column 104 and the alignment groove 705 work together to achieve precise positioning and prevent mis-insertion:

[0085] When the inner tube 109 is inserted into the channel of the connector 703, multiple sets of alignment posts 104 on the outer peripheral wall of the holding block 101 move synchronously with the holding block 101, gradually approaching the inner sidewall of the outer ring 701. Since the alignment posts 104 are asymmetrically distributed circumferentially and are matched one-to-one with the number and distribution position of the alignment grooves 705, the alignment posts 104 can be accurately aligned with the alignment grooves 705 on the inner sidewall of the outer ring 701 and smoothly inserted along the extension direction of the groove only when the male connector 1 and the female connector 7 are at the same preset angle.

[0086] During insertion, the sliding fit between the alignment post 104 and the alignment groove 705 forms a guiding constraint, limiting the circumferential rotational offset of the holding block 101 and ensuring precise alignment between the slot 103 on the outer periphery of the holding block 101 and the locking block 702 on the inner side of the outer ring 701. Simultaneously, because the alignment post 104 and the slot 103 are circumferentially offset, they do not interfere with each other during the fit, further ensuring the smoothness of the docking action and ultimately achieving stable docking of the male connector 1 and the female connector 7 at the only correct angle.

[0087] In one embodiment of this utility model, such as Figures 3-7 As shown, when the alignment post 104 of the male pipe connector 1 is fully inserted into the alignment groove 705 of the female pipe connector 7, the end of the inner pipe 109 extends beyond the bottom of the groove of the connector 703, and the length of the inner pipe 109 extending beyond the bottom of the groove is 2-5mm.

[0088] Specifically, as the alignment post 104 is fully inserted, the end of the inner tube 109 simultaneously extends beyond the bottom of the groove of the connector 703, i.e., the bottom of the fitting groove 704, and the extension length is controlled within 2-5mm. This length design ensures that the fluid outlet of the inner tube 109 is completely separated from the sealing area of ​​the connector 703, allowing the fluid to be directly delivered to the interior of downstream containers such as the drainage bottle, avoiding contamination or blockage caused by fluid residue near the sealing groove; and also avoids shaking caused by excessive insertion of the inner tube 109 by extending the short distance.

[0089] In one embodiment of this utility model, such as Figures 8-9 As shown, the male connector 1 also includes a movable tube 110, a movable tube end 111, and a return spring;

[0090] The movable tube 110 is movably sleeved inside the inner tube 109, and its inner wall is in sliding fit with the outer wall of the inner tube 109.

[0091] The reset spring is sleeved on the outside of the inner tube 109, with one end abutting against the holding block 101 and the other end abutting against the end of the moving tube 110 near the holding block 101;

[0092] The inner tube 109 has a limiting protrusion 112 on its wall, and the movable tube 110 has a pressing ball 113 that is adapted to the limiting protrusion 112 on its wall.

[0093] An elastic sealing membrane is provided between the movable tube end 111 and the inner tube 109.

[0094] Specifically, when the inner tube 109 is inserted into the channel of the connector 703, the moving tube end 111 first contacts the port of the connector 703 or the downstream structure and is subjected to thrust, which drives the moving tube 110 to slide along the outer wall of the inner tube 109 toward the holding block 101.

[0095] At this time, the reset spring sleeved on the outside of the inner tube 109 is compressed; at the same time, the pressing ball 113 on the wall of the moving tube 110 moves synchronously with the tube body until it contacts the limiting protrusion 112 on the wall of the inner tube 109. The limiting protrusion 112 blocks the pressing ball 113 from continuing to move, thereby limiting the maximum sliding distance of the moving tube 110 and preventing it from getting too close to the holding block 101.

[0096] During this process, the elastic sealing membrane between the inner tube 109 and the moving tube end 111 stretches and deforms synchronously with the extension of the moving tube 110, always covering the gap between the two to prevent fluid or contaminants from entering the gap.

[0097] When the male connector 1 and female connector 7 are unlocked and the inner tube 109 needs to be pulled out in reverse, the thrust during docking is released, and the moving tube 110 is pushed to reset along the outer wall of the inner tube 109 in a direction away from the holding block 101. The pressing ball 113 returns to the initial position with the moving tube 110, and the end of the moving tube 111 is simultaneously retracted to a state close to the free end of the inner tube 109.

[0098] At the same time, the elastic sealing membrane shrinks and deforms as the moving tube 110 resets, and tightly seals the gap between the inner tube 109 and the end of the moving tube 111 again, avoiding the residue of contaminants on the outside of the end of the moving tube 111 during the separation process, and ensuring cleanliness during the next docking.

[0099] In one embodiment of this utility model, such as Figures 3-5 As shown, the male pipe connector 1 also includes a split connector 105;

[0100] One end of the opening connector 105 is connected to the outer wall of the ring clamp 106, and the other end of the opening connector 105 extends to the outer side of the holding block 101.

[0101] The operator can push the exposed end of the opening connector 105 towards the holding block 101. The opening connector 105 stably transmits the external force to the ring pressing member 106, causing the ring pressing member 106 to slide along the outside of the inner tube 109, squeezing the locking block 702 out of the slot 103 to release the lock.

[0102] After unlocking, the ring clamp 106 is pushed back to its original position by the tension spring 107, and the opening connector 105 also returns to its initial extended position, ready for the next docking.

[0103] It also includes a block holder 13, the shape of which is adapted to the shape of the block holder 101. The block holder 13 is a block sleeve for further dustproof sealing.

[0104] An anal drainage bottle according to an embodiment of this utility model, such as Figures 1-11 As shown, the pipe joint in the above embodiment also includes a drainage pipe 2, a flushing pipe 3, and an anal tube 4;

[0105] The top of the drainage bottle 5 has two openings, one of which is fixedly connected to one end of the connector 703 of the female tube connector 7.

[0106] Another opening is provided with a partition 8, which has multiple sets of vent holes. The top edge of the drainage bottle 5 is fixedly connected to a sealing cap 6 by a connecting strap 9. The shape of the bottom cap of the sealing cap 6 is adapted to the shape of the opening at the partition 8.

[0107] One end of the drainage tube 2 is connected to the outlet tube 102 of the male connector 1;

[0108] Both the flushing tube 3 and the anal tube 4 are connected to the body of the drainage tube 2.

[0109] Specifically, the two openings at the top of the drainage bottle 5 have clearly defined functions. One opening is fixed to the connector 703 of the female tube connector 7 with an outwardly protruding butt joint structure, ensuring that the drainage fluid can flow stably into the bottle after the drainage tube 2 is connected through the outlet tube 102 of the male tube connector 1. The partition 8 at the other opening has multiple sets of concave ventilation holes, which can balance the air pressure inside and outside the drainage bottle 5 to avoid negative pressure hindering drainage. The ventilation holes of the partition 8 can also reduce the outflow of feces and reduce the risk of contamination when the drainage bottle 5 is accidentally tilted. The sealing cap 6, which is fixed to the top edge of the drainage bottle 5 by the connecting strap 9, is adapted to the patient's activity scenarios. When the patient needs to get out of bed or when an odor is generated in the drainage bottle 5, the sealing cap 6 can be placed on the opening with the partition 8 to prevent liquid leakage and block the spread of odor, improving the convenience and comfort of use.

[0110] Combining the characteristics of the pipe fittings, including male fitting 1 and female fitting 7, when the drainage bottle 5 needs to be replaced, the connection between the drainage tube 2 and the female fitting 7 can be quickly disconnected through the unlocking structure of the fittings. The drainage tube 2 is always connected to the outlet tube 102 of the male fitting 1, and with the relevant sealing design, liquid leakage is avoided during the separation process, further improving operational efficiency and hygiene safety.

[0111] In one embodiment of this utility model, such as Figure 10 As shown, the outer wall of the drainage bottle 5 is provided with scale lines 10, and the outer wall of the drainage bottle 5 is provided with a one-way chuck 11 and a chuck block 12.

[0112] One end of the one-way cassette 11 is fixed to the outer wall of the drainage bottle 5, and the other end of the one-way cassette 11 is detachably snapped into the cassette block 12.

[0113] Specifically, when the drainage bottle 5 needs to be fixed, it is snapped into the clip block 12. Through the one-way snap-fit ​​structure, the drainage bottle 5 is prevented from tipping over due to accidental collision or patient movement, thereby preventing drainage fluid leakage from polluting the environment or affecting the smoothness of drainage due to the tilt of the bottle.

[0114] In summary, the present invention provides an anal tube drainage bottle and pipe connector, in which a flushing tube is implanted inside the drainage tube. When drainage is blocked, flushing fluid can be injected directly to repeatedly clear the blockage without disassembling the pipe, thus avoiding drainage interruption or patient discomfort caused by tube disassembly. The vent not only balances the air pressure inside and outside the bottle, but also reduces the outflow of large amounts of feces when the drainage bottle is accidentally tipped over, thereby reducing the risk of environmental pollution.

[0115] The quick-release design of the male and female tube connectors allows for direct disconnection when changing drainage bottles, reducing the number of steps required. At the same time, the sealing ring and elastic sealing membrane at the connectors prevent liquid leakage during bottle changes, reducing the workload of medical staff in cleaning.
