[0037] like Figures 1 to 9 As shown, an embodiment of the present invention provides an excrement cleaner for urinary ostomy bag changing, comprising a base plate 1 and an ostomy bag 2 fixed on the outer wall of the base plate 1, wherein a bottom plate 4 is arranged on the side of the outer wall of the base plate 1 away from the ostomy bag 2; an auxiliary unit, wherein the auxiliary unit is connected to the bottom plate 4, and the unit assists in the replacement operation of the ostomy bag 2; a fixing unit, wherein the fixing unit is located inside and outside the base plate 1 and is connected to the bottom plate 4, and the fixing unit is used to fix the base plate 1 and the ostomy bag 2 to the bottom plate 4; the auxiliary unit comprises a base 3 arranged outside the base plate 1, wherein the two ends of the outer wall of the base 3 are symmetrically fixedly connected with fixing plates 8 located outside the lower end of the base plate 1, a plastic film 7 is arranged between the base 3 and the fixing plate 8, an upper mounting plate 12 is arranged on the top of the base 3, and the two ends of the top of the upper mounting plate 12 are symmetrically fixedly connected with side mounting plates 9, and the outer walls of one group of the side mounting plates 9 are fixedly connected with waterproof strips 10 extending to the surfaces of another group of the side mounting plates 9.

[0038] The auxiliary unit also includes a connecting ring 16 fixedly connected to the outer wall of the chassis 4 on one side close to the base plate 1, and blocks 15 are symmetrically fixedly connected at both ends of the outer wall of the connecting ring 16. Limiting strips 11 are symmetrically arranged on the top of the base 3. Two groups of the limiting strips 11 are respectively located on one side of the two groups of side mounting plates 9 close to the chassis 4. Elastic bands 13 are symmetrically arranged between the two groups of limiting strips 11. The lower ends of the two groups of elastic bands 13 are fixedly connected to the base 3, and the upper ends of the two groups of elastic bands 13 are respectively fixedly connected to the two groups of limiting strips 11. The ends of the two groups of limiting strips 11 close to each other are fixedly connected with multiple groups of latch teeth 14, and the outer walls of the latch teeth 14 and the latch blocks 15 close to each other are arranged as inclined structures.

[0039] First, the length of the connecting ring 16 and the fixing ring 5 is smaller than the protruding height of the stoma, and the bottom plate 4 is attached around the stoma of the patient. When the stoma bag 2 needs to be replaced, the connection between the base plate 1, the stoma bag 2 and the bottom plate 4 is first released by the fixing unit to take out the used base plate 1 and the stoma bag 2 for replacement. In this process, the plastic film 7 can be pulled first to form a bag opening between the plastic film 7 and the base 3 through the elasticity of the plastic film 7 itself, and then the stoma is cleaned with a cleaning liquid, and the liquid generated when cleaning the stoma and the secretions flowing out of the stoma can directly fall into the bag opening for temporary storage. After completing the cleaning of the stoma surface, the connection between the base plate 1, the stoma bag 2 and the bottom plate 4 is completed by the fixing unit, which is convenient for the patient's physiological use.

[0040] After the base plate 1 and the ostomy bag 2 are connected to the chassis 4, the upper ends of the two groups of limit strips 11 are pushed to bend the two groups of limit strips 11 in a direction away from each other. The deformation of the limit strips 11 drives the latch teeth 14 to separate from the latch blocks 15, thereby releasing the connection between the base 3 and the chassis 4. The base 3 can be taken out to clean the bag opening. Through the cooperation between the above parts, the entire bag opening replacement process can be disassembled to simplify the operating steps of each process and facilitate independent operation by the patient.

[0041] After flushing, the bag mouth can be restored under its own elastic force, and the base 3 is moved again to drive the two groups of limit strips 11 to be inserted back into the outer wall of the connecting ring 16. Through the restoring force of the elastic band 13 and the mutual engagement of the latch teeth 14 and the latch block 15, the connection operation between the base 3 and the chassis 4 can be completed.

[0042] like Figures 1 to 9As shown, the fixing unit includes a fixing ring 5 fixedly connected to the outer wall of the connecting ring 16 away from the chassis 4, one end of the inner wall of the fixing ring 5 is provided with a fixing hole 29, the outer wall of the fixing ring 5 is sleeved with a docking ring 6, one end of the outer wall of the docking ring 6 is fixedly connected with a mounting tube 17, the mounting tube 17 is internally movably provided with a limiting cross bar 19 extending to the inside of the fixing hole 29, the top of the mounting tube 17 is provided with a limiting slide groove 21, the fixing unit also includes a limiting pull rod 20 fixedly connected to the top of the limiting cross bar 19 and passing through the mounting tube 17, A spring 18 is arranged inside the mounting tube 17, and the two ends of the spring 18 are respectively abutted against the limiting cross bar 19 and the inner wall of the mounting tube 17, and a driving block 25 is arranged outside the upper end of the limiting pull rod 20. The fixing unit also includes an inner mounting plate 27 fixedly connected to the outer wall of the upper end of the docking ring 6, and a circular hole 28 is arranged inside the inner mounting plate 27. The top of the driving block 25 is fixedly connected to a limiting stopper 24, and the top of the limiting stopper 24 is fixedly connected to a connecting rod 23, and the connecting rod 23 passes through the ostomy bag 2 and extends to the top of the ostomy bag 2.

[0043] An angle limit block 30 is fixedly connected to the inside of the circular hole 28, the outer diameter of the limit block 24 matches the inner diameter of the circular hole 28, the limit block 24 is movably arranged inside the inner mounting plate 27 through the circular hole 28, the angle limit block 30 is fitted with the end of the limit block 24, and a positioning groove 26 is provided on the surface of the driving block 25 away from the end of the limit block 24.

[0044] The limit stop block 24 can be driven to rotate by rotating the connecting rod 23, and the limit stop block 24 drives the driving block 25 to rotate. The driving block 25 rotates its outer wall to contact the limit pull rod 20, and pushes the limit pull rod 20 to move laterally inside the limit slide groove 21 and drives the limit cross bar 19 to move. The limit cross bar 19 moves and separates from the fixing hole 29, and the connection between the base plate 1 and the ostomy bag 2 and the chassis 4 can be released to facilitate the operation of the auxiliary unit.

[0045] During this process, the connecting rod 23 is rotated 90 degrees clockwise, which can drive the limit block 24 to rotate 90 degrees, so that the plane of the outer wall of the limit block 24 is against the angle limit block 30. At this time, the driving block 25 also completes a 90-degree rotation driven by the limit block 24, and after the driving block 25 pushes the limit pull rod 20, the positioning groove 26 is sleeved on the outer wall of the limit pull rod 20. At this time, the connection between the base plate 1 and the ostomy bag 2 and the chassis 4 can be kept disconnected, so as to facilitate the user to use it.

[0046] like Figure 8 As shown, a sliding portion 22 is provided on a side of the limiting cross bar 19 away from the spring 18 , and a surface of the sliding portion 22 is also provided as an inclined structure.

[0047] Through this structure, when the limiting cross bar 19 contacts the docking ring 6, the sliding portion 22 is forced to shrink and retract into the interior of the mounting tube 17. After the mounting tube 17 is aligned with the fixing hole 29, the limiting cross bar 19 enters the interior of the fixing hole 29 under the resetting action of the spring 18 to complete the limiting operation of the connection between the base plate 1 and the ostomy bag 2 and the chassis 4.

[0048] The specific working process of the technical solution of the present invention is as follows:

[0049] First, by rotating the connecting rod 23, the limit stop block 24 can be driven to rotate, and the rotation of the limit stop block 24 drives the driving block 25 to rotate. The driving block 25 rotates its outer wall to contact the limit pull rod 20, and pushes the limit pull rod 20 to move laterally inside the limit slide groove 21 and drives the limit cross bar 19 to move. The limit cross bar 19 moves and separates from the fixing hole 29, and the connection between the base plate 1 and the ostomy bag 2 and the chassis 4 can be released to facilitate the operation of the auxiliary unit.

[0050] Then, the used base plate 1 and stoma bag 2 are taken out for replacement. In this process, the plastic film 7 can be pulled first to form a bag opening between the plastic film 7 and the base 3 through the elasticity of the plastic film 7 itself, and then the stoma is cleaned with a cleaning liquid. The liquid generated when cleaning the stoma and the secretions flowing out of the stoma can directly fall into the bag opening for temporary storage. After the cleaning of the stoma surface is completed, the connection between the base plate 1 and the stoma bag 2 and the bottom plate 4 is completed through the fixing unit, which is convenient for the patient's physiological use.

[0051] After the base plate 1 and the ostomy bag 2 are connected to the bottom plate 4, the upper ends of the two groups of limit strips 11 are pushed to bend the two groups of limit strips 11 in a direction away from each other. The deformation of the limit strips 11 drives the latch teeth 14 to separate from the latch blocks 15, thereby releasing the connection between the base 3 and the bottom plate 4. The separate base 3 can be taken out to clean the bag opening. Through the mutual cooperation between the above parts, the entire bag opening replacement process can be disassembled to simplify the operating steps of each process and facilitate independent operation by the patient.

[0052] After flushing, the bag mouth can be restored under its own elastic force. The base 3 is moved again to drive the two sets of limit strips 11 to be inserted back into the outer wall of the connecting ring 16. Through the restoring force of the elastic band 13, the locking teeth 14 and the locking blocks 15 are engaged with each other, and the connection operation between the base 3 and the chassis 4 can be completed.

[0053] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0054] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
