DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0021] Please refer to Figs. 1-3 The urine drainage device with convenient control has the advantage of high applicability.

[0022] Specifically, the sleeve 1 is provided with a urine inlet 2 and a urine outlet 3 at the upper end and the bottom outer wall, respectively;

[0023] The blocking piece 4 is arranged in the sleeve 1.

[0024] The elastic support 5 is arranged in the blocking piece 4 and can be used to elastically support the blocking piece 4 to block or connect the urine inlet 2 and the urine outlet 3.

[0025] The adjusting piece 6 is arranged in the elastic support 5 and penetrates the blocking piece 4, and is used to adjust the elastic strength of the elastic support 5 to control the bladder urine drainage pressure.

[0026] In the embodiment, when in the initial state, the blocking piece 4 abuts against the inner wall of the sleeve 1 to block the urine inlet 2 and the urine outlet 3; when urine flows into the sleeve 1 and accumulates on the top of the blocking piece 4, the blocking piece 4 always maintains the blocking state, and when the urine pressure exceeds the pre-tightening force of the elastic support 5, the blocking piece 4 compresses the elastic support 5 downward and separates from the sleeve 1, so that the urine flows into the sleeve 1 through the gap between the blocking piece 4 and the sleeve 1 and is discharged through the urine outlet 3; as the urine flows out, the pressure of the urine on the blocking piece 4 decreases until it is less than the pre-tightening force of the elastic support 5, the elastic support 5 releases and pushes the blocking piece 4 to abut against the sleeve 1 to block the urine inlet 2 and the urine outlet 3. Before use, the elastic strength of the elastic support 5 can be adjusted by the adjusting piece 6 arranged, the elastic strength of the elastic support 5 changes, the water pressure of the urine pushing the blocking piece 4 to shrink also changes, and then different pressures are adjusted according to different application scenarios, so as to improve the comfort of the patient's urination place and increase the applicability.

[0027] Specifically, referring to Figs. 2-3 The blocking piece 4 includes a bottom shell 41 arranged inside the sleeve 1, a blocking frame 42 arranged in a sliding manner at the outer wall of the bottom shell 41, and a sealing ring 43 arranged in a sleeving manner at the outer wall of the blocking frame 42 and abutting against the inner wall of the sleeve 1.

[0028] In the embodiment, the blocking frame 42 can slide up and down on the outer wall of the bottom shell 41, and when the blocking frame 42 pushes the sealing ring 43 to abut against the inner wall of the sleeve 1 under the elastic action of the elastic support 5, the urine inlet 2 and the urine outlet 3 can be blocked or connected.

[0029] Specifically, referring to Figs. 2-3The elastic support 5 comprises two limiting racks 51 arranged in the bottom shell 41 respectively, two sliding shafts 52 arranged in the two limiting racks 51 respectively, a bearing rack 53 arranged between the two sliding shafts 52, and a spring 54 arranged on the top of the bearing rack 53 and abutting against the inner wall of the blocking rack 42.

[0030] In the embodiment, the spring 54 can push the blocking rack 42 upward by the elastic force, and when the water pressure of the urine formed on the top of the blocking rack 42 is too large, the spring 54 can be pressed downward by the blocking rack 42. The bearing rack 53 can slide up and down between the two limiting racks 51 through the sliding shaft 52, so as to change the compression state of the spring 54 by changing the distance between the bearing rack 53 and the blocking rack 42. After the compression state of the spring 54 is changed, the elastic force generated by the spring 54 will also change, thereby changing the water pressure of the urine pushing the blocking rack 42 downward.

[0031] Specifically, referring to Figs. 2-3 , the adjusting part 6 comprises a rotating rod 61 arranged in the bottom shell 41 and penetrating the bottom shell 41 at the bottom end, a plug rod 62 arranged in the rotating rod 61, an adjusting screw rod 63 threadedly penetrating the bottom shell 41 and slidingly sleeved on the outer wall of the plug rod 62 at the lower end, the upper end of the adjusting screw rod 63 being rotatably arranged in the bearing rack 53, a limiting strip 64 arranged on the outer wall of the plug rod 62 and slidingly inserted into the bottom of the adjusting screw rod 63, and a fixing screw rod 65 arranged on the outer wall of the bottom shell 41 and threadedly penetrating the bottom shell 41 at one end and abutting against the outer wall of the rotating rod 61.

[0032] In the embodiment, before use, the rotating rod 61 can be rotated to drive the adjusting screw rod 63 through the limiting of the limiting strip 64. When the adjusting screw rod 63 is rotated, the thread pushing generated by the adjusting screw rod 63 can change the height of the bearing rack 53, thereby adjusting the compression state of the spring 54. The limiting strip 64 arranged can keep the adjusting state of the adjusting screw rod 63 after the adjusting screw rod 63 is lifted on the outer wall of the plug rod 62. After adjustment, the fixing screw rod 65 can be screwed to the rotating rod 61 to fix the rotating rod 61.

[0033] Specifically, referring to Figs. 2-3 , the bottom shell 41 is embedded with a piston ring 7, and the outer wall of the piston ring 7 is slidingly abutted against the inner wall of the blocking rack 42.

[0034] In the embodiment, the piston ring 7 arranged can slidingly seal between the bottom shell 41 and the blocking rack 42, so as to prevent the urine from entering the bottom shell 41 through the gap therebetween.

[0035] Specifically, referring to Figs. 2-3 , the bottom of the sleeve 1 is arranged in an inclined manner and recessed in the middle, and the urine outlet 3 is arranged at the lowest position of the outer wall of the sleeve 1.

[0036] In this embodiment, the inclination of the bottom of the sleeve 1 can better guide the urine to the urine outlet 3 through the slope generated, and urine accumulation in the sleeve 1 is avoided as much as possible.

[0037] Although the embodiments of the present application have been shown and described, it should be understood by those ordinary skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
