TECHNICAL FIELD

[0001] The present application relates to the technical field of drainage nursing, in particular to a drainage device for urology nursing. BACKGROUND

[0002] Urology is a branch of medicine that deals with the urinary tract in both men and women, and the male reproductive system. It is mainly subdivided from surgery. The male urinary and reproductive systems are closely related, while the female urinary tract opens on the vulva, and regardless of men and women, the urinary tract and reproductive tract are closely related, and the diseases of the two often affect each other. Urology can be further subdivided into urology, urinary tract stones, urinary disorders, pediatric urology, sexual dysfunction, male infertility, and other sub-specialties. The drainage device of the urology department is developed for patients who cannot urinate independently. The urinary catheter is directly inserted into the patient's bladder to help the patient urinate.

[0003] The search index in the authorized publication number: CN 117180535 A discloses a urology drainage nursing device, which comprises a bottom connecting rod, an intermediate position of the upper side wall of the bottom connecting rod is movably connected with a drainage bag mounting rod, an intermediate position of the upper side wall of the drainage bag mounting rod is movably connected with a top connecting rod, one side wall top of the top connecting rod is fixedly connected with a pipe clamp fixing pipe, the pipe clamp fixing pipe is movably connected with a telescopic pipe, the front side wall of the pipe clamp fixing pipe and located away from the top connecting rod one end is threadedly connected with a top butterfly bolt, and the pipe clamp fixing pipe is fixed in the pipe clamp fixing pipe through the top butterfly bolt. The growing pipe clamp fixing pipe and the anti-backflow valve solve the problem that the existing drainage nursing device is easy to be closed when used, and the urine is easy to backflow under the change of the pressure in the patient's bladder.

Subsequently, the screw handle is rotated in the opposite direction until the locking screw is tightly against the rectangular groove of the side wall of the movable shaft and stops, thereby realizing convenient adjustment of the height of the pipe clamp.

[0021] 3. In the present invention, through the provided pitch adjustment unit, when it is necessary to adjust the pitch angle of the pipe clamp fixing pipe, the connecting seat can be pulled to make the electric telescopic tube rotate synchronously with the rotating rod until the anti-bending pipe clamp at the telescopic end of the electric telescopic tube reaches the appropriate pitch angle and stops. At this time, under the elastic force of the telescopic spring, the engaging seat automatically engages between the adjacent gear teeth of the gear plate, thereby realizing convenient adjustment of the pitch angle of the pipe clamp fixing pipe. When it is necessary to change the position of the pipe clamp, the telescopic end of the electric telescopic tube is extended and retracted, thereby driving the anti-bending pipe clamp to move in the horizontal direction. In conjunction with the lifting unit, the height adjustment of the anti-bending pipe clamp can be realized. In conjunction with the steering unit, the direction adjustment of the anti-bending pipe clamp can be realized, thereby realizing convenient change of the position of the pipe clamp.

[0037] As Figure 3 indicated, the steering unit 2 comprises a fixed box 201 mounted on the top of the moving unit 1, a rotating through hole opened on the top of the fixed box 201, a rotating shaft 202 movably penetrating and arranged in the rotating through hole, and a driving piece 203 arranged in the fixed box 201. The driving piece 203 is arranged to drive the rotating shaft 202 to rotate.

[0038] As Figure 1 indicated, the lifting unit 3 comprises a containing groove 301 opened on the top of the rotating shaft 202, a moving shaft 302 movably penetrating and arranged in the containing groove 301, a locking piece 303 arranged between the moving shaft 302 and the rotating shaft 202, an anti-backflow valve 304 mounted on the side wall of the moving shaft 302, and a drainage tube speed adapter 305 arranged on the input end and the output end of the anti-backflow valve 304.

[0039] As Figure 3 indicated, the pitch adjusting unit 4 comprises a rotating seat 405 movably mounted on the top of the moving shaft 302, a U-shaped seat 401 mounted on the side wall of the rotating seat 405, a limiting piece 404 arranged on the side of the U-shaped seat 401, a rotating rod 402 movably mounted in the U-shaped seat 401 and extending into the U-shaped seat 401, and a connecting seat 403 mounted on the side wall of the rotating rod 402. The rotating rod 402 rotates to drive the connecting seat 403 on the side of the rotating rod 402 to rotate synchronously.

[0040] As Figure 1 indicated, the moving unit 1 comprises a base 101 and a locking universal wheel 102 mounted on the bottom of the base 101. The locking universal wheel 102 is arranged to facilitate the convenient movement of the entire drainage device.

[0041] As Figure 4As shown, the driving member 203 comprises a worm gear 2031 mounted on the side wall of the rotating shaft 202, a worm 2032 movably arranged in the fixed box 201 and engaged with the worm gear 2031, and a first driving motor 2033 mounted on the input end of the worm 2032. When the first driving motor 2033 drives the worm 2032 to rotate, the worm 2032 can drive the worm gear 2031 to rotate.

[0042] As shown in Figure 3 As shown, the locking member 303 comprises a threaded hole formed in the side wall of the accommodating groove 301, a rectangular slot formed in the side wall of the moving shaft 302, a locking screw 3031 movably arranged in the threaded hole, and a screw handle 3032 mounted on the input end of the locking screw 3031.

[0046] As shown in Figure 2 As shown, the fixing member 502 comprises an anti-bending pipe clamp 5021 mounted on the telescopic end of the electric telescopic pipe 501, and an anti-slip leather pad 5022 mounted on the inner side wall of the anti-bending pipe clamp 5021. The anti-slip leather pad 5022 prevents the drainage tube from accidentally falling out of the anti-bending pipe clamp 5021.

[0047] When the orientation of the pipe clamp needs to be adjusted, the first driving motor 2033 drives the worm 2032 to rotate, the worm 2032 meshes with the worm gear 2031 to drive the worm gear 2031 to rotate synchronously with the rotating shaft 202, so that the orientation of the clamping unit 5 changes, thereby conveniently adjusting the orientation of the pipe clamp; when the height of the pipe clamp needs to be adjusted, the screw handle 3032 is rotated to drive the locking screw 3031 to move away from the rectangular groove in the side wall of the moving shaft 302 until it is completely separated, at which time the moving shaft 302 can be pulled to move up and down in the accommodating groove at the top of the rotating shaft 202 until the appropriate height is reached, then the screw handle 3032 is reversely rotated until the locking screw 3031 abuts against the rectangular groove in the side wall of the moving shaft 302, thereby conveniently adjusting the height of the pipe clamp.
