Please continue to refer to Fig. 9 A, which may also include a gear unit 37, be separately connected the fixing piece 43 (i.e. waistband) and first actuation module 317 or second actuation module 327, the gear unit 37 is using the patient in exhaling The expansion of abdomen is done work when patient respiratory (also that is, tear actuation together with the waistband) with shrinking when suction, thus drive this first 327 actuation of actuation module 317 or the second actuation module.

Fig. 9 B is please referred to, in an embodiment, when being provided that second drainage pump 32 in driving structure 30, the transmission Unit 37 can couple (being fixedly connected) in the second actuation module 327 of second drainage pump 32, and using the patient in breathing When abdomen expansion and shrink work done and drive second actuation module 327 to carry out one-directional rotation actuation.

Specifically, the inner ring of unilateral bearing 3791 is fixedly connected with the second actuation module 327, outside unilateral bearing 3791 Circle connection waistband 43, and can be rotated under the effect of pullling of waistband 43.One end of wind spring 3792 is connected to the unilateral bearing 3791 Outer ring, the other end embedded in the driving assembly 33 shell on, for providing the reset of the unilateral bearing 3791.Upon inhalation, Abdominal circumference increases, outer ring rotation under the pullling of waistband 43 of the unilateral bearing 3791, and the inner ring of the unilateral bearing 3791 is also therewith Rotation, and then second actuation module 327 is driven to rotate synchronously；Upon exhalation, abdominal circumference reduces, and the outer ring of unilateral bearing 3791 exists Wind spring 3792 drives lower reset, at this point, the inner ring of unilateral bearing 3791 remains stationary, alternately with breathing, can drive The outer ring of unilateral bearing 3791 constantly rotates and resets, and the inner ring of unilateral bearing 3971 only rotates in one direction, thus Realize the intermittent one-directional rotation of the second actuation module 327.

Fig. 9 C to Fig. 9 F is please referred to, when being provided that first drainage pump 31 in the driving structure, then the gear unit 37 be the first actuation module 317 of first drainage pump 31 of being movably connected.Specifically, the gear unit 37 is movable Ground connects the operating bar 3173, converts the operating bar for the expansion of patient abdomen when breathing and contraction work done 3173 linear motion.Lead to shown in connection relationship such as Fig. 9 C between the gear unit 37 and first actuation module 317 It crosses pivot joint and interlocks；It is interlocked shown in Fig. 9 E by a cam mechanism；It is interlocked shown in Fig. 9 E by a crank mechanism；Or It is interlocked shown in person Fig. 9 F using the attraction principle of electromagnetism.

Referring to Fig. 10, the gear unit 37 further includes a shell 371, an elastic element 375 in specific embodiment An and cam 377 a, wherein guide rail 373 is provided on the shell 371, which is set on the guide rail 373, this is convex Wheel 377 one end connect the elastic element 375, the other end connects the fixing piece 43, wherein when the patient in breathing when, can draw The variation of its abdominal circumference is played, and pulls the fixing piece 43 (waistband), so that the cam 377 is in the elastic element 375 and the fixing piece 43 mutually pull down is moved back and forth along the guide rail 373, to drive first actuation module 317 or second actuation module 327 actuations.

Specifically, when the patient inhales, the fixing piece 43 is pullled because its abdominal circumference becomes larger, so that cam 377 is being located at It is slided to the right under the pullling of fixing piece 43 on the right side of it along guide rail 373；As the patient exhales, due to because its abdominal circumference becomes smaller consolidating of making Determine part 43 pull power disappearance so that cam 377 be located at its on the left of elastic element 375 pullling under along guide rail 373 to Left sliding, as a result, can reciprocatingly sliding and drive first actuation module 317 or second actuation module 327 by cam 377 Periodic actuation.

In conclusion the drainage device of the application is between stoma and storage of urine by being arranged driving structure, to be stagnant It stays and provides power in the urine of distal ureteral, so as to effectively drain the urine being stranded in ureter；In addition, by setting Set the adsorption piece of the inner tubal wall from the end for extending into the ureter by the skin surface of the stoma, be stoma with it is defeated It is formed and is tightly connected between urinary catheter, to prevent the leakage of urine, and the service life of stoma can be extended to reduce its replacement Frequency, and the adsorption piece effectively can also avoid stoma from falling off in use process；In addition, the stoma of the application need to only be stretched The end for entering the ureter can be convenient the replacement operation of stoma；Furthermore pass through the waist that driving structure is fixed on to patient Portion is driven the urine in stoma export ureter as driving force using the abdominal circumference variation generated using patient respiratory, is not necessarily to Be powered, thus the drainage device of the application also have the advantages that it is environmentally protective.

Finally, it should be noted that above embodiments are only to illustrate the technical solution of the embodiment of the present application, rather than it is limited System；Although the application is described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: its It is still possible to modify the technical solutions described in the foregoing embodiments, or part of technical characteristic is equal Replacement；And these are modified or replaceed, each embodiment technical solution of the application that it does not separate the essence of the corresponding technical solution Spirit and scope.
