The upper end face of the bearing shell 11 with an opening can support the lower end face of the drive element 6.

That is, the present application employs a special driving member 6 structure, which realizes the movement of the driving flushing plate 56 under specific conditions, avoids the long-term pressing of the stoma to influence the recovery of the stoma, and improves the stoma cleaning effect.

Furthermore, the top of the flushing plate 56 is provided with a limiting groove 57, the upper end of the ostomy bag 5 is provided with a limiting block 58 which can be matched with the limiting groove 57 in a penetrating way, and when the limiting block 58 is matched with the limiting groove 57, one side of the flushing plate 56 is propped against the inner wall of the ostomy bag 5. The connection mode between the limiting block 58 and the limiting groove 57 can be threaded connection, interference fit and the like, and further installation and positioning of the flushing plate 56 are achieved.

Further, the driving member 6 comprises a housing 64 having a liquid chamber 61, a piston chamber 62 and a sliding chamber 63, one end of the sliding chamber 63 is communicated with the piston chamber 62, a valve rod 65 slidably connected with the sliding chamber 63 is arranged in the sliding chamber 63, one end of the valve rod 65 penetrates through the ostomy bag 5 to be in threaded connection with the flushing plate 56, the other end of the valve rod 65 is detachably connected with a piston 66, the piston 66 is located in the piston chamber 62, a spring 67 is arranged on one side of the piston 66 facing the valve rod 65, and one end of the spring 67, which is far away from the piston 66, is connected with the inner wall of the piston chamber 62. Specifically, the following are mentioned: the cross-sectional width of the piston 66 is greater than the cross-sectional width of the slide chamber 63 so that the piston 66 can only move within the piston chamber 62.

The liquid chamber 61 is located above the sliding movement chamber 63, an outflow passage 68 communicating the liquid chamber 61 and the sliding movement chamber 63 is further provided in the housing 64, and the outflow passage 68 is located below the liquid chamber 61. A spray passage 69 is provided in the valve stem 65 for communicating the flush plate 56 with the slide chamber 63, and the valve stem 65 is slidable relative to the housing 64 to have a first position in which the spray passage 69 communicates with the outflow passage 68, and a second position in which the spray passage 69 and the outflow passage 68 are isolated from each other.

The liquid channel 70 and the gas channel 71 are both provided with a sealing plug 72, and the sealing plug 72 is a prior art, and the details can be seen in a rubber plug in an infusion bottle. In specific use, the needle of the syringe is inserted into the sealing plug 72, the external air is injected into the air passage 71, and the physiological saline is injected into the liquid passage 70.

The use process is as follows:

the position of the washing plate 56 is fixed by using the limiting block 58 to match with the limiting groove 57 above the washing plate 56, and then the valve rod 65 is in the second position, and the position of the piston 66 in the piston cavity 62 is kept unchanged, at this time, the spring 67 is in a stretching state. The syringe draws 10-30ml of saline and injects the saline into the fluid chamber 61 through the fluid passage 70 without being filled, and since the outflow passage 68 is located at the bottom of the fluid chamber 61, the saline may not flow through the outflow passage 68 to be discharged toward the outflow passage 68. Then, gas is injected into the liquid chamber 61 through the gas passage 71, so that the pressure in the space above the physiological saline is increased. In the above-described condition, the rinse plate 56 is disposed away from the stoma in the stoma area 54 and does not interfere with the normal discharge from the stoma.

When cleaning of the stoma is required. At this time, the limiting block 58 is only required to be separated from the matching with the limiting groove 57, the piston 66 is driven to move towards the stoma direction under the action of the elastic potential energy of the spring 67, the flushing plate 56 is driven to move towards the stoma direction, and the valve rod 65 is located at the first position at this time, so that the spraying channel 69 is communicated with the outflow channel 68. The physiological saline in the liquid cavity 61 is discharged to the outflow channel 68, the spraying channel 69 to the plurality of spraying ports 55 on the flushing plate 56 in sequence under the action of upper high pressure, and finally the close-range spraying cleaning of the stoma is realized, so that the sanitary condition of the stoma is improved, and the cleaning liquid can be temporarily stored in the drainage part. In the foregoing, the core innovation points of the present application are: since the stoma is mostly exposed to the outside of the body, the mucous membrane of the stoma is generally 1-2cm higher than the skin, and thus the stoma penetrates 1-2cm into the stoma area 54 when the connecting portion 53 of the ostomy bag 5 is attached to the skin. And this application is when not needing to making a mouthful wash, washes the distance between board 56 and the mouth of making and is drawn big as far as possible, avoids washing board 56 to make a mouthful extrusion, and does not influence the mouth of making and normally excretes. When the stoma is required to be cleaned, the valve rod 65 is changed from the second position state to the first position state, the plurality of spraying ports 55 on the flushing plate 56 automatically discharge water to realize spraying and cleaning of the wound, and the spraying and cleaning effect is good.

In addition, the driving member 6 of the present application is externally detachably connected to the flushing plate 56 in the ostomy bag 5, i.e. the driving member 6 may not be mounted when cleaning is not required, which facilitates use. Even if the driving member 6 is installed, the driving member 6 can be supported by the upper end of the bearing housing 1. When cleaning is required: one end of the valve rod 65 is threaded through the ostomy bag 5 to the flushing plate 56, and during assembly, the piston 66 at the end of the valve rod 65 is moved away from the flushing plate 56 due to the fixation of the flushing plate 56 until the end of the piston 66 abuts against the side wall of the inner wall of the piston chamber 62, at which point the spring 67 is stretched and the valve rod 65 is in the second position.

Further, with the diameter d of the shower opening 55 on the flushing plate 56, when the valve rod 65 is in the first position state, the distance between the shower opening 55 on the flushing plate 56 and the stoma is L1=150 d; when the valve rod 65 is in the second position, the distance between the shower opening 55 and the stoma in the flushing plate 56 is L2 > 200 d. Thus, the displacement of the piston 66 in the piston cavity 62 is greater than 50 d.

The essence of spray cleaning is as follows: the wastes on the surface of the stoma are cleaned by the impact force of the physiological saline, namely the impact force of the physiological saline is larger than the adhesive force of the wastes and the surface of the stoma, and the wastes can be peeled and washed away from the stoma. When the physiological saline is sprayed out from the spraying port 55, according to the research of the water jet theory, the optimal target distance exists, namely the target distance which generates the maximum cleaning effect on the surface of the object to be cleaned is generally the position which is 100-200 times of the diameter of the nozzle away from the outlet of the nozzle. In the present application, the water jet theory is adopted for practical application.

It is to be emphasized that: since the flush plate 56 is disposed in the stoma area 54, and therefore has exceptional circumstances such as being contaminated or clogged with fecal matter, the prior art has used a snap-fit connection, i.e., removable and replaceable, of the flush plate 56 to the stoma bag. In the present application, however, the flushing plate 56 is not only removable and replaceable, but also is used to creatively increase the distance between the flushing plate 56 and the stoma, thereby reducing the possibility of the flushing plate 56 becoming contaminated or clogged with fecal matter.

Further, the housing 64 includes a first housing 64 and a second housing 64 detachably connected to each other, and the first housing 64 and the second housing 64 enclose the piston chamber 62. By means of the above-described detachable connection arrangement, opening of the piston chamber 62 and thus assembly between the piston 66 and the valve stem 65 is achieved.
