[0026] The drawings of the utility model will be described below in conjunction with Figures 1-5 ​The utility model discloses further detailed explanation to the specific embodiment of the utility model.

[0027] By Figures 1-5 Give, the utility model discloses a bag body 1, the upper and lower sides of bag body 1 are communicated with liquid inlet pipe 2, liquid outlet pipe 3 respectively, to reduce the probability of non-liquid material causing the blockage in the process of drainage, the rear side of the middle part of bag body 1 is provided with a connecting port 4, the inside of bag body 1 is fixedly connected with a connecting bag 5 at the position corresponding connecting port 4, the upper and lower sides of connecting bag 5 are provided with through hole 6, the inside of connecting bag 5 is equipped with a detachable filter frame 7, filter frame 7 is inclined to set relative to bag body 1, the upper side of filter frame 7 is provided with a plurality of filter area 8, filter area 8 is filter screen structure, can filter the non-liquid material in the process of drainage, the middle part of every filter area 8 is equipped with a cleaning mechanism 9 for cleaning filter area 8;

[0028] Need to explain, bag body 1, connecting bag 5 are made of medical high polymer material, such as polyethylene, polyamide or polyvinyl chloride etc., can produce deformation, the upper side of bag body 1 is fixedly connected with a hanging rope,

[0029] When using, bag body 1 can be hung by hanging rope, in the process of drainage, liquid inlet pipe 2 can be connected with the drainage tube of patient, and the drainage liquid can enter bag body 1 through liquid inlet pipe 2, then pass through hole 6, and the non-liquid material is filtered under the action of filter frame 7, the liquid enters the lower side of filter frame 7, and the non-liquid material is filtered and retained on the upper side of filter frame 7, since filter frame 7 is inclined to set, in the process of drainage, the non-liquid material can be accumulated in the lower half of filter frame 7 under the action of gravity, which can reduce the probability of filter frame 7 being blocked, when the non-liquid material is filtered more, filter frame 7 is blocked, the upper surface of filter frame 7 can be cleaned by cleaning mechanism 9, so that the accumulated liquid on the upper side of filter frame 7 can be filtered and emptied, and filter frame 7 can be conveniently cleaned.

[0030] Further, by Figures 1-5 Give, to improve the purpose of filtering efficiency, cleaning mechanism 9 includes a limiting frame 10 fixedly connected with filter frame 7, the left and right sides of limiting frame 10 are provided with a knob slot 11, the inside of limiting frame 10 is equipped with a sliding block 12 that can slide up and down along limiting frame 10, the left and right sides of sliding block 12 are connected with a plurality of connecting blocks 13, the side, away from sliding block 12 of every connecting block 13 is fixedly connected with a cleaning plate 14, the lower side of cleaning plate 14 contacts with filter area 8;

[0031] Further, by Figures 1-5 Give, the upper and lower sides of knob slot 11 are wave-shaped, the side, close to sliding block 12 of every connecting block 13 is provided with two inclined surfaces;

[0032] Further, by Figures 1-5 It is given that in order to facilitate the staff operation, the lower side of the sliding block 12 is fixedly connected with a reset rod 15, the outer side of the reset rod 15 is sleeved with a reset sleeve 16 fixedly connected with the limiting frame 10, and the inner side of the reset sleeve 16 is provided with a reset spring 17 abutting against the reset rod 15 and the reset sleeve 16 at the upper and lower sides respectively;

[0033] It should be noted that the connecting block 13 is made of plastic material and can produce elastic deformation. By providing the inclined surface on the connecting block 13, the contact area between the connecting block 13 and the sliding block 12 can be reduced, so that the sliding block 12 and the connecting block 13 are rotatably connected. The two sides of the connecting block 13 are always in contact with the side wall of the driving groove 11. Since the driving groove 11 is wave-shaped, the connecting block 13 will rotate relative to the sliding block 12 and the driving groove 11 under the action of the driving groove 11 during the upward and downward movement of the sliding block 12, so as to clean the filtering area 8 by the cleaning plate 14. As the displacement distance of the sliding block 12 increases, the connecting block 13 will eventually move with the sliding block 12 relative to the driving groove 11. Further, the total length of the cleaning plate 14 is greater than the width of the filtering area 8 on one side of the limiting frame 10. When the displacement distance of the sliding block 12 is too large, the cleaning plate 14 can be driven to push the non-liquid substances downward.

[0034] In use, each connecting block 13 and cleaning plate 14 is in a downwardly inclined state. When it is necessary to clean the filtering area 8, the pressing plate 20 can be pressed downward, and the pressing plate 20 drives each sliding block 12 to slide downward. Due to the mutual cooperation and jamming of the connecting block 13 and the driving groove 11, the connecting block 13 drives the cleaning plate 14 to rotate relative to the sliding block 12, so as to clean the filtering area 8.

[0035] Further, by Figures 1-5 It is given that in order to facilitate the cleaning of the filtering frame 7, the left and right sides of the upper side of the limiting frame 10 are fixedly connected with a cooperating block 18, and the inner side of the connecting bag 5 is provided with a cooperating groove corresponding to the position of the cooperating block 18. The cooperating block 18 and the cooperating groove form a detachable structure of the filtering frame 7.

[0036] Further, by Figures 1-5 It is given that in order to facilitate the disassembly of the filtering frame 7 by medical staff, the rear side of the filtering frame 7 is provided with a pressing plate 20, the rear side of each sliding block 12 is fixedly connected with the pressing plate 20, the lower side of the pressing plate 20 is provided with an operating plate 21 fixedly connected with the filtering frame 7, and the lower side of the operating plate 21 is provided with an arc-shaped groove.

[0037] In use, medical staff can use the arc-shaped groove to apply downward pressure to the pressing plate 20 for cleaning the filtering area 8.

[0038] Further, by Figures 1-5 It is given that the back side of the bag body 1 is fixedly connected with a first magnet 22 on the left and right, and the back side of each first magnet 22 is provided with a second magnet 23 fixedly connected with the filter frame 7.

[0039] In use, the bag body 1 can be hung by the hanging rope first, and in the process of drainage, the liquid inlet pipe 2 is connected with the drainage tube of the patient, and the drainage liquid enters the bag body 1 through the liquid inlet pipe 2, and then passes through the hole 6 and is filtered by the filter frame 7, and the liquid enters the lower side of the filter frame 7, and the non-liquid substance is filtered and retained on the upper side of the filter frame 7. Since the filter frame 7 is inclined, the non-liquid substance will accumulate in the lower half of the filter frame 7 under the action of gravity in the process of drainage, so as to reduce the probability of blockage of the filter frame 7. When the non-liquid substance is filtered more, the upper surface of the filter frame 7 can be cleaned by the cleaning mechanism 9, so that the accumulated liquid on the upper side of the filter frame 7 can be filtered and emptied, and the filter frame 7 can be conveniently cleaned. When it is necessary to empty the bag body 1, the liquid can be emptied through the liquid outlet pipe 3.

[0040] The utility model discloses novel structure, clever idea, simple and convenient operation, through the design effectively reduce the probability of blockage caused by non-liquid substance in the process of drainage, improve the filtering efficiency, make the staff operation convenient, and the medical staff is convenient to the filter frame 7 is dismantled and cleaned.

[0041] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
