Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to a urination function exercise device. Background Art

[0002] After prostate surgery, the urination function often needs to be restored and exercised. Traditional urinary catheters are simply urine drainage tools and lack the function of exercising the patient's urination function. During the rehabilitation process, the patient needs to gradually restore the ability of autonomous urination, but the existing technology has deficiencies in this regard and cannot effectively adjust the urination pressure according to the patient's recovery situation, which is not conducive to the patient's rapid restoration of normal urination function. Therefore, a device that can help prostate patients exercise their urination function after surgery is needed.

[0003] The methods described in this section are not necessarily methods that have been previously conceived or adopted. Unless otherwise specified, no method described in this section should be considered prior art solely because it is included in this section. Similarly, unless otherwise specified, the problems mentioned in this section should not be considered to have been recognized in any prior art. Summary of the Invention

[0004] To overcome the problems existing in the related art, the present invention discloses a urination function exercise device.

[0005] To achieve the above object, a technical solution adopted by the present invention is:

[0006] A urination function exercise device includes a urinary catheter and a pressure switch communicated with the urinary catheter. The pressure switch includes an upper shell, a lower shell, a first piston and an elastic member. The upper shell is a hollow structure with an open lower end, and the lower shell is a hollow structure with an open upper end. The upper end of the upper shell is communicated with the urinary catheter, and the lower shell is threadedly connected to the outside of the upper shell. When the lower shell rotates relative to the upper shell, it can move up and down relative to the upper shell. The lower side of the lower shell has a liquid discharge port. The first piston is longitudinally and sealingly slidably connected in the upper shell. A liquid guide channel penetrating the circumferential surface of the first piston is opened at the upper end of the first piston. The elastic member is arranged in the lower shell to push the first piston upward so that the upper end of the first piston abuts against the top wall of the upper shell. When the upper end of the first piston abuts against the top wall of the upper shell, the side end of the liquid discharge port will be closed by the inner wall of the upper shell.

[0007] Further, the upper end of the upper shell has a liquid inlet, and the urinary catheter is connected to the liquid inlet.

[0008] Further, a limiting member is arranged on the side surface of the upper shell. When the lower shell moves upward relative to the upper shell until it abuts against the limiting member, the limiting member will limit the lower shell from continuing to move upward.

[0009] Further, it further includes a sealing assembly disposed inside the lower shell. The sealing assembly includes a first piston chamber, a second piston chamber, a second piston, and a third piston. The upper parts of both the first piston chamber and the second piston chamber are open and the lower parts communicate with each other. The second piston is longitudinally and sealingly slidably connected inside the first piston chamber. The third piston is longitudinally and sealingly slidably connected inside the second piston chamber. The shape of the third piston matches the shape of the upper shell. The parts of the first piston chamber and the second piston chamber between the second piston and the third piston are filled with hydraulic liquid. The elastic member is further configured to push the second piston downward, so that the second piston pushes the hydraulic liquid inside the first piston chamber downward, and the hydraulic liquid inside the second piston chamber pushes the third piston upward, so that the upper end of the third piston tightly abuts against the lower end of the upper shell to form a seal.

[0010] Further, the sealing assembly further includes a sealing ring located between the upper end of the third piston and the lower end of the upper shell.

[0011] Further, the sealing ring is fixedly connected to the upper end of the third piston.

[0012] Further, the sealing assembly further includes an inner sliding cylinder and an outer sliding cylinder. The inner sliding cylinder and the outer sliding cylinder are fixedly connected to the inner bottom wall of the lower shell at intervals inside and outside. The liquid discharge port is located inside the inner sliding cylinder. The second piston is sealingly slidably connected between the inner sliding cylinder and the outer sliding cylinder. The circumferential outer side wall of the inner sliding cylinder, the circumferential inner side wall of the outer sliding cylinder, and the inner bottom wall of the lower shell jointly enclose the first piston chamber. The third piston is sealingly slidably connected between the inner sliding cylinder and the lower shell. The circumferential outer wall of the inner sliding cylinder, the circumferential inner wall of the lower shell, and the inner bottom wall of the lower shell jointly enclose the second piston chamber.

[0013] Further, a plurality of through slots penetrating inside and outside are formed on the lower side of the outer sliding cylinder. The first piston chamber and the second piston chamber communicate through the through slots.

[0014] Further, the elastic member is a threaded spring, and the upper and lower ends of the threaded spring respectively abut against the first piston and the second piston.

[0015] Further, both the upper shell and the lower shell are made of transparent materials, and anti-slip patterns are provided on the outer sides of both the upper shell and the lower shell.

[0016] The postoperative urination function exercise device for prostate patients of the present invention has significant advantages compared with the prior art.

[0017] In terms of urination pressure regulation, the existing technologies either lack effective regulation functions or are complex to regulate, making it difficult to accurately adjust according to the patient's recovery situation. In contrast, for the present invention, the opening pressure of the first piston can be adjusted by simply rotating the lower shell to change the compression degree of the elastic member. Medical staff can easily set an appropriate urination pressure threshold according to the patient's postoperative recovery stage, realizing personalized and progressive exercise, which is more conducive to the recovery of the patient's autonomous urination function.

[0018] In terms of sealing performance, other similar devices often have urine leakage problems due to poor sealing structures, affecting the use and easily causing infections. The sealing component of the present invention uses hydraulic transmission. The elastic member is used to push the second piston, causing the hydraulic liquid to act on the third piston to tightly abut against the upper shell. A sealing ring is provided to further enhance the effect. At the same time, each piston seals and slides in the corresponding cavity, and structures such as the inner sliding cylinder and the outer sliding cylinder cooperate to prevent urine from leaking through channels such as the installation gap, greatly improving the reliability and safety.

[0019] In addition, during the use of traditional urination devices, it is difficult for medical staff to observe the internal situation and the operation is inconvenient, increasing the work difficulty. The upper shell and the lower shell of the present invention are made of transparent materials, facilitating medical staff to observe internal situations such as urine flow and piston position, enabling timely problem discovery. Moreover, the anti-slip pattern design of the outer shell makes it more convenient and stable for medical staff to rotate the lower shell, effectively improving the efficiency and quality of medical care, and providing a better solution for the postoperative urination function exercise of prostate patients.

Detailed implementation mode

[0028] The present invention will be further described below with reference to the accompanying drawings.

[0029] Refer to Figures 1-5 As shown, the postoperative urination function exercise device for prostate patients in this embodiment includes a urinary catheter (not shown in the figure) and a pressure switch 2 communicated with the urinary catheter. The pressure switch 2 is a key part of this device, and it includes an upper shell 21, a lower shell 22, a first piston 23 and an elastic member 24.

[0030] The upper shell 21 is a hollow structure with an open lower end, and the lower shell 22 is a hollow structure with an open upper end, and the two cooperate with each other. The upper end of the upper shell 21 is communicated with the urinary catheter, and the lower shell 22 is threadedly connected to the outside of the upper shell 21. By rotating the lower shell 22, the lower shell 22 can move up and down relative to the upper shell 21. The lower side of the lower shell 22 has a liquid discharge port 221 for discharging urine.

[0031] The first piston 23 is longitudinally and sealingly slidably connected inside the upper shell 21, and a liquid guiding channel 231 penetrating the circumferential surface of the first piston 23 is opened at its upper end. The elastic member 24 is arranged inside the lower shell 22, and its function is to push the first piston 23 upward so that the upper end of the first piston 23 keeps abutting against the top wall of the upper shell 21. When the upper end of the first piston 23 abuts against the top wall of the upper shell 21, the side end of the liquid discharge port 221 will be closed by the inner wall of the upper shell 21 to achieve a closing effect and prevent the urine in the urinary catheter from leaking out.

[0032] In this embodiment, the upper end of the upper shell 21 has a liquid inlet 211, and the urinary catheter is connected to the liquid inlet 211 to ensure that urine smoothly enters the pressure switch from the urinary catheter. A limiting member 212 is arranged on the side surface of the upper shell 21. When the lower shell 22 moves upward relative to the upper shell 21 until it abuts against the limiting member 212, the limiting member 212 will limit the lower shell 22 from continuing to move upward to prevent damage to the device caused by excessive rotation.

[0033] The device further includes a sealing assembly 3 disposed within the lower housing 22. The sealing assembly 3 includes a first piston chamber 31, a second piston chamber 32, a second piston 34, and a third piston 35. The upper portions of both the first piston chamber 31 and the second piston chamber 32 are open and the lower portions communicate with each other. The second piston 34 is longitudinally and sealingly slidably connected within the first piston chamber 31, and the third piston 35 is longitudinally and sealingly slidably connected within the second piston chamber 32. The shape of the third piston 35 matches the shape of the upper housing 21. The portions of the first piston chamber 31 and the second piston chamber 32 between the second piston 34 and the third piston 35 are filled with hydraulic fluid. The elastic member 24 not only pushes the first piston 23 upward but also is used to push the second piston 34 downward, causing the second piston 34 to push the hydraulic fluid within the first piston chamber 31 downward, enabling the hydraulic fluid within the second piston chamber 32 to push the third piston 35 upward, such that the upper end of the third piston 35 is in close contact with the lower end of the upper housing 21 to form a seal, preventing urine from leaking through the installation gap between the upper housing 21 and the lower housing 22.

[0034] The sealing assembly 3 further includes a sealing ring 33 located between the upper end of the third piston 35 and the lower end of the upper housing 21 to enhance the sealing effect. The sealing ring 33 can be fixedly connected to the upper end of the third piston 35.

[0035] In addition, the sealing assembly 3 further includes an inner sliding cylinder 36 and an outer sliding cylinder 37. The inner sliding cylinder 36 and the outer sliding cylinder 37 are fixedly connected to the inner bottom wall of the lower housing 22 at intervals inside and outside. The liquid discharge port 221 is located inside the inner sliding cylinder 36. The second piston 34 is sealingly slidably connected between the inner sliding cylinder 36 and the outer sliding cylinder 37. The circumferential outer side wall of the inner sliding cylinder 36, the circumferential inner side wall of the outer sliding cylinder 37, and the inner bottom wall of the lower housing 22 jointly enclose to form the first piston chamber 31. The third piston 35 is sealingly slidably connected between the inner sliding cylinder 36 and the lower housing 22. The circumferential outer wall of the inner sliding cylinder 36, the circumferential inner wall of the lower housing 22, and the inner bottom wall of the lower housing 22 jointly enclose to form the second piston chamber 32. The lower side of the outer sliding cylinder 37 is provided with a plurality of through grooves 371 penetrating inside and outside, and the first piston chamber 31 communicates with the second piston chamber 32 through the through grooves 371, ensuring that the hydraulic fluid can flow smoothly between the two piston chambers.

[0036] In this embodiment, the elastic member 24 is a threaded spring, and its upper and lower ends are respectively in contact with the first piston 23 and the second piston 34, providing appropriate elastic force for the movement and sealing of the entire device. Both the upper housing 21 and the lower housing 22 are made of transparent materials, facilitating medical staff to observe the internal situation. Anti-slip patterns are provided on the outer sides of both the upper housing 21 and the lower housing 22, facilitating medical staff to operate and rotate the lower housing 22.

[0037] When urine enters the upper shell 21 from the catheter, under normal circumstances, due to the elastic member 24 pushing the first piston 23 upward so that it abuts against the top wall of the upper shell 21, the urine cannot flow out. As the urine in the bladder increases and the pressure rises, when the pressure overcomes the elastic force of the elastic member 24 and the sealing resistance inside the device, the first piston 23 moves downward. When the first piston 23 moves downward to the side end of the liquid guiding channel 231 to release the seal, the urine will enter the lower shell 22 through the liquid guiding channel 231, and thus the urine will be discharged from the liquid discharge port 221.

[0038] Medical staff can adjust the compression degree of the elastic member 24 by rotating the lower shell 22, thereby adjusting the pressure required for the first piston 23 to open, realizing the adjustment of the patient's urination pressure, and achieving the purpose of exercising the urination function.

[0039] The hydraulic transmission structure in the sealing assembly 3, under the action of the elastic member 24, ensures good sealing between the third piston 35 and the upper shell 21, preventing urine leakage.

[0040] When assembling the device, first install the first piston 23 into the upper shell 21 to ensure its longitudinal sealing and sliding, and then place the elastic member 24 into the lower shell 22. Then install each component of the sealing assembly 3, including the second piston 34, the third piston 35, etc., at the corresponding positions in the lower shell 22 according to the design, paying attention to the sealing and sliding connection of each piston and the filling of the hydraulic liquid. After that, connect the lower shell 22 to the outside of the upper shell 21 by means of threads, and finally connect the catheter to the liquid inlet 211 of the upper shell 21. A collection container can be connected to the liquid discharge port 221 to collect urine.

[0041] When using this device for prostate patients after surgery, medical staff adjust the compression degree of the elastic member 24 by rotating the lower shell 22 according to the patient's physical condition and recovery stage, so as to set an appropriate urination pressure threshold. When the urine accumulates in the patient's bladder and the generated pressure reaches the set threshold, the urine is discharged through the pressure switch 2. During the use process, medical staff can observe the internal situation of the device through the transparent upper shell 21 and lower shell 22, and at the same time use the anti-slip pattern to conveniently operate the rotation of the lower shell 22 to further adjust the urination pressure. As the patient's recovery improves, the urination pressure threshold can be gradually increased to continuously exercise the patient's urination function.

[0042] During the use process, the sealing performance of the device should be regularly checked, especially the sealing condition of the sealing ring 33. If there is wear or aging, it should be replaced in time. At the same time, check whether the elasticity of the elastic member 24 is normal and whether the sliding of each piston is smooth. During the use process, pay attention to keeping the device clean to avoid urine residue causing infection. When the patient's urination function recovers to a certain extent, the device can be removed according to the doctor's advice.

[0043] The urination function exercise device of the present invention can flexibly adjust the urination pressure by simply rotating the lower shell 22 according to the patient's recovery condition, effectively helping prostate patients recover the autonomous urination function after surgery.

[0044] In the device, the sealing component 3 ensures good sealing performance through designs such as hydraulic transmission and the sealing ring 33, preventing urine leakage and improving the reliability and safety of the device.

[0045] The upper shell 21 and the lower shell 22 are made of transparent materials and designed with anti-slip patterns, which are convenient for medical staff to observe and operate, and are conducive to improving the efficiency and quality of medical care.

Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
