Description

Technical Field

[0001] This invention relates to the field of medical urination device technology, and specifically to an extended urination device. Background Technology

[0002] For patients with difficulty urinating, hospitals now mostly use medical urination devices to perform active urination. These devices are mostly pump-driven and perform active urination.

[0003] However, pumps are usually installed outside the urinary tube and connected to it; as a result, the required pump power is relatively large, increasing the equipment cost. At the same time, as the length of the urinary tube increases, the negative pressure suction force generated by the pump gradually decreases.

[0004] This requires a relatively larger pump power, increasing equipment costs. At the same time, as the length of the urination tube increases, the suction pressure generated by the pump gradually decreases.

[0005] Therefore, there is a need for a urination device that can effectively increase attractiveness and facilitate voluntary urination. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides an extended urination device to improve suction and facilitate urine discharge.

[0007] An extended urination device includes: a urination tube, one end of which extends into the urethra; the urination tube includes an extension main tube; a fixing part disposed on the urination tube; the fixing part includes an expansion flexible tube disposed on the outer surface of the extension main tube and communicating with the extension main tube; and an internal pump installed inside the urination tube, the internal pump including a motor, a rotary reciprocating mechanism, and a piston; the motor drives the rotary reciprocating mechanism to move; the piston is mounted on the rotary reciprocating mechanism and reciprocates within the urination tube.

[0008] Furthermore, it also includes a one-way valve, which is installed inside the urination tube and close to the internal drainage pump. In practical applications, the one-way valve in this design is a miniature one-way valve; this setting ensures that the liquid flowing through this point will not flow back, greatly facilitating the formation of liquid flow.

[0009] Furthermore, the urination tube also includes an installation tube disposed at one end of the extension main tube; the installation tube has an outer tube and an inner tube, the inner tube being disposed inside the outer tube; the inner tube has a sealing partition; the sealing partition has a one-way installation hole; the one-way valve is installed in the one-way installation hole. In actual design, this design provides installation space for the aforementioned one-way valve and allows the urination tube to be divided into two areas by the sealing partition; one area is the extension main tube, which extends into the urethra and bladder, similar to a suction tube; and the other area is the device area for achieving the urine suction function.

[0010] Furthermore, the inner tube is also provided with an installation sleeve; the installation sleeve is disposed on the sealing partition; the internal discharge pump is installed inside the installation sleeve. In actual operation, this installation sleeve is mainly used to facilitate the components of the internal discharge pump; thus ensuring the stability of the aforementioned internal discharge pump and making its installation stable.

[0011] Furthermore, the internal pump also includes a cylinder liner, and the mounting sleeve has at least one drain hole; the drain hole is located on the wall of the mounting sleeve; the cylinder liner is installed inside the mounting sleeve and is located below the drain hole and closer to the motor. In actual design, this design references the principle of a piston pump, facilitating the reciprocating motion of the cylinder liner and piston to achieve urination; when the piston is working, as the piston moves away from the one-way valve, the one-way valve opens, and urine flows into the mounting sleeve through the one-way valve, with some urine flowing out from the drain hole; until the piston moves closer to the one-way valve, the one-way valve closes under pressure, and the piston continues to move closer to the one-way valve; urine continues to flow out through the drain hole under pressure. In this way, active urination is achieved.

[0012] Furthermore, the rotary reciprocating mechanism includes at least two spirally wound lines; one end of each of the two lines is mounted on the motor, and the other end of each of the two lines is mounted on the other side of the piston. In practical design, the purpose of this design is to achieve two effects: the rotation of the piston and its up-and-down reciprocating motion. To achieve this effect, the lines are made of high-strength carbon fiber, and during operation, the motor operates in a combination of forward and reverse rotation; in this way, the technical effects of the piston's up-and-down reciprocating motion and rotation can be achieved.

[0013] Furthermore, the piston is installed inside the cylinder liner and reciprocates within the cylinder liner; one side of the piston is also provided with at least one helical blade, located away from the motor. In practical applications, the purpose of this design is to enhance the urination effect. The helical blade design is intended to achieve a spiral suction effect similar to a waterspout; when the helical blade descends with the piston's rotation, the negative pressure it generates is similar to a spiral pressure airflow, thus suctioning out more urine and making urination more convenient.

[0014] As can be seen from the above technical solution, the present invention provides an extended urination device with the following beneficial effects;

[0015] (1) In actual work, the design of the extension tube that can be extended into the urethra is adopted, which achieves a closer distance and better urination effect. Of course, if the patient's body allows, it can also be extended to the bladder, which makes it closer and more convenient to urinate.

[0016] (2) In order to avoid the extension tube suddenly detaching from the urethra during urination, the design also adopts the design of an expansion flexible tube, which allows urine to flow into the expansion flexible tube when it flows out of the extension tube, so as to facilitate fixation and avoid sudden detachment; of course, in order to achieve this effect, the opening of the expansion flexible tube is larger than the diameter of the extension tube; so that urine can flow out of the expansion flexible tube.

[0017] (3) Furthermore, by placing the internal drainage pump inside the urination tube, it is close to the urine source, making it convenient to drain the urine. Attached Figure Description

[0024] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0025] The basic implementation examples are as follows: Figures 1 to 3 As shown:

[0026] Example 1:

[0027] Example 1:

[0028] like Figures 1-3 As shown, this embodiment provides an extended urination device that can improve suction and facilitate urine discharge.

[0029] An extended urination device includes: a urination tube 1, one end of which extends into the urethra; the urination tube 1 includes an extension main tube 11; a fixing part 2, which is disposed on the urination tube 1; the fixing part 2 includes an expandable flexible tube 21; the expandable flexible tube 21 is disposed on the outer surface of the extension main tube 11 and communicates with the extension main tube 11; and an internal pump 3, which is installed inside the urination tube 1, the internal pump 3 including a motor 31, a rotary reciprocating mechanism 32, and a piston 33; the motor 31 drives the rotary reciprocating mechanism 32 to move; the piston 33 is mounted on the rotary reciprocating mechanism 32 and reciprocates within the urination tube 1. In practical applications, this design utilizes an extension main tube 11 that extends into the urethra, achieving a closer distance and better urination efficiency. Of course, if the patient's physical condition permits, it can be extended all the way to the bladder, further reducing the distance and facilitating urination. To prevent the extension tube 11 from suddenly detaching from the urethra during urination, the design also incorporates an expandable flexible tube 21. This design allows urine to flow into the expandable flexible tube 21 as it flows from the extension tube 11, facilitating fixation and preventing sudden detachment. To achieve this, the opening of the expandable flexible tube 21 is larger than the diameter of the extension tube 11, allowing urine to flow out easily. Furthermore, by placing the internal pump 3 inside the urination tube 1, it is positioned close to the urine source, facilitating the dispensing of urine.

[0030] In this embodiment, a one-way valve 4 is also included. The one-way valve 4 is installed inside the urination tube 1 and close to the internal drainage pump 3. In actual use, the one-way valve 4 in this design is a miniature one-way valve 4; this setting ensures that the liquid flowing through this point will not flow back, greatly facilitating the formation of liquid flow.

[0031] In this embodiment, the urination tube 1 further includes an installation tube 12, which is disposed at one end of the extension tube 11. The installation tube 12 has an outer tube 121 and an inner tube 122, with the inner tube 122 disposed inside the outer tube 121. The inner tube 122 has a sealing partition 101. The sealing partition 101 is provided with a one-way installation hole 102. The one-way valve 4 is installed in the one-way installation hole 102. In actual design, this design provides installation space for the one-way valve 4 and divides the urination tube 1 into two areas by the sealing partition 101. One area is the extension tube 11, which is similar to a suction tube and can extend into the urethra and bladder. The other area is the device area that can perform the suction function.

[0032] In this embodiment, the inner tube 122 is further provided with an installation sleeve 201; the installation sleeve 201 is disposed on the sealing partition 101; the internal discharge pump 3 is installed inside the installation sleeve 201. In actual operation, the installation sleeve 201 is mainly used to facilitate the components of the internal discharge pump 3; thus ensuring the stability of the internal discharge pump 3 and making its installation stable.

[0033] In this embodiment, the internal pump 3 further includes a cylinder liner 34, and the mounting sleeve 201 also has at least one drain hole 202. The drain hole 202 is disposed on the pipe wall of the mounting sleeve 201. The cylinder liner 34 is installed inside the mounting sleeve 201, located below the drain hole 202, and close to the motor 31. In actual design, this design references the principle of the piston 33 pump, which facilitates the reciprocating motion of the cylinder liner 34 and the piston 33 to achieve urination. When the piston 33 is working, when the piston 33 moves away from the one-way valve 4, the one-way valve 4 opens, and urine flows into the mounting sleeve 201 through the one-way valve 4, with some urine flowing out from the drain hole 202. Until the piston 33 moves closer to the one-way valve 4, the one-way valve 4 closes under pressure, and the piston 33 continues to move closer to the one-way valve 4. Under pressure, urine continues to flow out through the drain hole 202. In this way, active urination is achieved.

[0034] In this embodiment, the rotary reciprocating mechanism 32 includes at least two spirally wound lines 321; one end of each line 321 is mounted on the motor 31, and the other end of each line 321 is mounted on the other side of the piston 33. In practical design, the purpose of this design is to achieve two effects: rotation and reciprocating motion of the piston 33. To achieve this effect, the lines 321 are made of high-strength carbon fiber. During operation, the motor 31 operates in a combination of forward and reverse rotation; thus, the technical effects of reciprocating motion and rotation of the piston 33 can be achieved.

[0035] In this embodiment, the piston 33 is installed inside the cylinder liner 34 and reciprocates within the cylinder liner 34. One side of the piston 33 is also provided with at least one spiral blade 331, located away from the motor 31. In practical applications, the purpose of this design is to enhance the urination effect. The spiral blade design aims to achieve a spiral suction effect similar to a waterspout. When the spiral blade descends with the piston 33, the negative pressure it generates is similar to a spiral pressure airflow, thus suctioning out more urine and making urination more convenient.

[0036] In actual work, firstly, the extension tube 11 of the urinary catheter 1 is inserted into the urethra, and depending on the patient's physical condition, it can be extended into the bladder; then the motor 31 is started to rotate, and after 5-10 seconds, the motor 31 is reversed; after urine is found to be discharged, wait for a certain period of time until it is completely discharged, then the motor 31 is turned off; and the extension tube 11 is removed.

[0037] In summary, this extended urination device is not only reasonably designed but also simple to operate. Through its rotating, lifting, and reciprocating structure, it can achieve a spiral liquid flow similar to a dragon sucking water, greatly improving the drainage effect. Therefore, it is suitable for industry promotion.
