Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of perianal ostomy bags, in particular to a perianal ostomy bag drainage structure. Background Art
[0002] For some patients who are bedridden for a long time and lack the ability to take care of themselves, excrement disposal is a nursing problem. At present, medical staff generally place bedpans under the beds with defecation holes for post-defecation disposal. The operation is simple and convenient, but this method of treating excrement will expose the excrement to the outside world and easily pollute the environment. Therefore, some medical staff will also use ostomy bags pasted around the anus to receive the excrement, so as to avoid polluting the environment. However, the size of the perianal ostomy bags is limited and they need to be changed frequently, which increases the burden on medical staff.
[0003] Existing ostomy bags need to be replaced in time. In order to reduce the labor of accompanying personnel, there are also some ostomy bags that are continuously used on the market. However, there are the following defects during use: the form of excrement is affected by factors such as diet, work and rest, and disease. If the excrement is sticky, the excrement is easily stuck in the ostomy bag, forming a blockage that is difficult to discharge, and eventually causing the adhesive label of the ostomy bag to burst and fall off, polluting the surrounding environment. Medical staff need to deal with it in time, which increases manpower and material costs. Utility Model Content
[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a perianal ostomy bag drainage structure to solve the background technical problems.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;
[0025] See also Figure 1-5 In the utility model, a perianal ostomy bag drainage structure comprises an ostomy bag body 2 and a fixed tube 1, a docking tube 3 connected to the fixed tube 1 is installed on the right side of the fixed tube 1, a connecting tube 4 plugged into the inside of the docking tube 3 is installed on the left side of the ostomy bag body 2, an electric push rod 5 is installed on the fixed tube 1, the bottom end of the electric push rod 5 extends to the inside of the fixed tube 1 and is fixedly connected to a piston plate 6, the outer side of the piston plate 6 is slidably connected to the inside of the fixed tube 1, an opening and closing component 7 is arranged inside the docking tube 3, a discharge port 8 is opened inside the fixed tube 1, two closing plates 9 hinged to the inside of the fixed tube 1 are arranged inside the discharge port 8, the two closing plates 9 are symmetrically arranged on the left and right and are in contact with each other on the opposite sides, a first spring 10 is installed inside the discharge port 8, and the top end of the first spring 10 is fixedly connected to the bottom of the closing plate 9.
[0026] The opening and closing assembly 7 includes a fixed block 71, a sliding block 72 and a second spring 73. The fixed block 71 is installed to the inner top wall of the docking tube 3, the sliding block 72 is slidably connected to the inner bottom wall of the docking tube 3, the fixed block 71 is in contact with the opposite side of the sliding block 72, and the second spring 73 is installed between the inner bottom wall of the docking tube 3 and the left side of the sliding block 72.
[0027] In the utility model, when it is necessary to discharge excrement, the electric push rod 5 can be started to drive the piston plate 6 to move upward. At this time, due to the first spring 10 resisting the closing plate 9, negative pressure is then generated in the fixed tube 1, and the sliding block 72 will be sucked. At this time, the fixed block 71 is separated from the sliding block 72, and then the excrement will be introduced into the docking tube 3 along the connecting tube 4, and then be inside the fixed tube 1. Then the electric push rod 5 drives the piston plate 6 to reset. During this process, there is no negative pressure in the fixed tube 1, so that the second spring 73 will resist the sliding block 72 to reset, so that it contacts the fixed block 71, so that the inside of the docking tube 3 is in a closed state, and then the piston plate 6 will squeeze the excrement, so that the closing plate 9 is squeezed open, and then the discharge process is carried out. After the discharge contact, the first spring 10 will drive the closing plate 9 to reset. The user can regularly introduce water and disinfectant into the interior of the ostomy bag body 2 for cleaning and disinfection.
[0028] See also Figure 1-2 , wherein: an annular tube 11 is installed inside the ostomy bag body 2, a water guide pipe 12 passing through the ostomy bag body 2 is installed on the annular tube 11, and a group of evenly distributed drainage holes 13 are opened at the bottom of the annular tube 11.
[0029] In the utility model, an external water source can be introduced into the annular tube 11 along the water guide pipe 12, and then sprayed to the inner wall of the ostomy bag body 2 along the drainage hole 13 to dilute the excrement.
[0030] See also Figure 1-4 , wherein: the left side of the sliding block 72 is fixedly connected with a protective cover 14 , the lower side of the protective cover 14 is fixedly connected to the inner bottom wall of the butt pipe 3 , and the second spring 73 is located inside the protective cover 14 .
[0031] In the utility model, the protective cover 14 is used to protect the second spring 73, thereby reducing the rust caused by water and excrement and extending the service life.
[0032] See also Figure 1-3 , wherein: two abutment blocks 15 are integrally formed inside the fixed tube 1 , and the bottom of the abutment blocks 15 contacts the top of the closing plate 9 .
[0033] In the present invention, the abutment block 15 is used to limit the closing plate 9, so as to reduce the occurrence of excessive upward movement.
[0034] The above is a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
