This application claims priority to Taiwanese Utility Model Patent Application No. 110206551, filed on Jun. 7, 2021.
The disclosure relates to a urethral catheterization system, and more particularly to a urethral catheterization system, a urinary catheter conveying device thereof, and a method of using the same.
A urinary catheter is used for being inserted through a patient's urethra into the patient's bladder to help the patient drain his bladder. However, since the urinary catheter is flexible, when it is manually inserted into an external urethral orifice of a glans of a patient by a person, usually, a nursing staff, the nursing staff must have substantial experiences to achieve accurate insertion of the urinary catheter. Inaccurate or incorrect insertion of the urinary catheter may require repeated insertion into the glans, which can discomfort the patient. In addition, in some cases, a patient needs to insert the urinary catheter into his external urethral orifice by himself or by his family member when the patient is not at a medical institution. Therefore, there is a need to facilitate assembly of a urinary catheter onto a patient's penis.
Therefore, an object of the disclosure is to provide a urinary catheter conveying device that can alleviate at least one of the drawbacks of the prior art.
According to the disclosure, the urinary catheter conveying device is adapted for guiding a urinary catheter to a penis, and includes a sleeve assembly, a conveying assembly and a controller. The sleeve assembly is adapted to be disposed on the penis, and includes a sleeve member that is adapted for sleeving onto a glans of the penis and that has a guiding hole adapted to be registered with an external urethral orifice of the glans. The conveying assembly includes a casing and a conveying mechanism. The casing is removably mounted to the sleeve member. The conveying mechanism is disposed in the casing, and is adapted for advancing the urinary catheter to the guiding hole such that the urinary catheter is inserted into the external urethral orifice through the guiding hole. The controller is electrically coupled to the conveying mechanism and is adapted for controlling the conveying mechanism to advance the urinary catheter to the guiding hole.
Another object of the disclosure is to provide a urinary catheterization system that can alleviate at least one of the drawbacks of the prior art.
According to the disclosure, the urinary catheterization system includes a urinary catheter and the urinary catheter conveying device as mentioned above.
Still another object of the disclosure is to provide a method of using a urinary catheterization system that can alleviate at least one of the drawbacks of the prior art.
According to the disclosure, the method for using the urinary catheterization system includes steps of: a) assembling a sleeve assembly onto a penis; b) assembling the sleeve assembly with a conveying assembly and a urinary catheter; c) controlling the conveying assembly to advance the urinary catheter to a guiding hole of a sleeve member of the sleeve assembly by a controller so that the urinary catheter is inserted into an external urethral orifice of a glans of the penis through the guiding hole.

The accommodating space 715 is adjacent to the rear surface 713, accommodates the conveying mechanism 73, opens upwardly at a top end of the casing body 710, and has two opposite ends. The lid body 711 is removably disposed on the casing body 710 so that the lid body 711 closes the accommodating space 715 and is operable to be opened. By virtue of the lid body 711 being operable to be opened, maintenance of the conveying mechanism 73 in the accommodating space 715 is relatively convenient. The first casing passage 716 is recessed in the rear surface 713, spatially communicates with one of the opposite ends of the accommodating space 715, and directs the inserting end 21 of the urinary catheter 2 to extend through the accommodating space 715. The second casing passage 717 spatially communicates with the positioning groove 714 and the other one of the opposite ends of the accommodating space 715, is aligned with the guiding hole 613 of the sleeve member 61, and directs the inserting end 21 of the urinary catheter 2 to extend through the guiding hole 613. In the first embodiment, a cross section of each of the first casing passage 716 and the second casing passage 717 corresponds in shape to the cross section of the urinary catheter 2 (i.e., the cross section of each of the first casing passage 716 and the second casing passage 717 is circular).
The casing 71 further includes a casing connector unit 720 that is removably connectable to the sleeve connector unit 615, and a plurality of mounting grooves 722. Specifically, the mounting grooves 722 are recessed in the inner dome-shaped surface 718, are spaced apart from each other, and spatially communicate with the positioning groove 714. In the first embodiment, the mounting grooves 722 are angularly spaced apart from each other, and the casing connector unit 720 includes a plurality of magnetic components 721 that are respectively bonded into the mounting grooves 722, that are flush with the inner dome-shaped surface 718, and that are respectively and magnetically attracted to the magnetic components 616 of the sleeve connector unit 615.
The conveying mechanism 73 is adapted for advancing the urinary catheter 2 to the guiding hole 613 of the sleeve member 61 such that the urinary catheter 2 is inserted into the external urethral orifice 114 of the glans 112 through the guiding hole 613. The conveying mechanism 73 includes a circuit board 731, two motors 732, two conveyor wheels 733, a processing unit 734, a wireless communication unit 735, a rechargeable battery 736 and an electrical connector 737. The motors 732 are mounted to the circuit board 731. The conveyor wheels 733 are respectively connected to top ends of the motors 732. The processing unit 734, the wireless communication unit 735, the rechargeable battery 736 and the electrical connector 737 are mounted to the circuit board 731. The conveyor wheels 733 are spaced apart from each other, and cooperatively clamp the urinary catheter 2 when the urinary catheter 2 extends through the first casing passage 716 into the accommodating space 715. Referring further to
The processing unit 734 is electrically coupled to the motors 732, the wireless communication unit 735 and the rechargeable battery 736, and controls the motors 732 to switch between an on state, in which the motors 732 urge the conveyor wheels 733 to rotate, and an off state, in which the conveyor wheels 733 cease to rotate. The wireless communication unit 735 transmit electrical signals via Bluetooth or Wi-Fi. The rechargeable battery 736 supplies electric power to the motors 732, the processing unit 734 and the wireless communication unit 735. A portion of the electrical connector 737 is exposed from the casing body 710, and is adapted to be connected to a power cable (not shown). Via the power cable, the electrical connector 737 transmits external electrical energy to the rechargeable battery 736 to charge the rechargeable battery 736.
The pressure sensor 3 is wirelessly and electrically coupled to the wireless communication unit 735 of the conveying mechanism 73. When the processing unit 734 of the conveying mechanism 73 receives one of the first and second pressure signals from the pressure sensor 3, the processing unit 734 switches the motors 732 into the off state so that the motors 732 cease to rotate or advance the conveying wheels 733.
The controller 8 is configured to be portable, and is wirelessly and electrically coupled to the wireless communication unit 735 of the conveying mechanism 73 so that the controller 8 is operable to wirelessly control the conveying assembly 7. Specifically, the controller 8 includes a power on button 81, a power off button 82, a forward movement button 83, a rearward movement button 84 and an emergency stop button 85. When the power on button 81 is pressed, the conveying assembly 7 is switched to a power-on state. When the power off button 82 is pressed, the conveying assembly 7 is switched to a power-off state. When the forward movement button 83 is pressed, the conveying assembly 7 is switched to a forward conveying state to advance the urinary catheter 2. When the rearward movement button 84 is pressed, the conveying assembly 7 is switched to a rearward conveying state to move the urinary catheter 2 rearward. When the emergency stop button 85 is pressed, the conveying assembly 7 is in a stop state to stop the urinary catheter 2 from moving. By pressing the different buttons of the controller 8, the conveying assembly 7 can be switched among the abovementioned operation states.
It is noted that, in certain embodiments, the controller 8 may be, but not limited to, a smart phone that is operable to control the conveying assembly 7 to switch among the abovementioned operation states via a mobile application therein.
By virtue of the first and second bands 63, 64 winding around the penis shaft 111, and by virtue of the first and second bands 63, 64 being fastened to each other via the hook-surfaced components 632 and the loop-surfaced components 642 thereof, the sleeve assembly may suit penis shafts in different girth and length. Furthermore, by virtue of the loop-surfaced components 642 being respectively disposed on the opposite surfaces of the band body 641 of the second band 64, and by virtue of the hook-surfaced components 632 being respectively disposed on the opposite surfaces of the band body 631 of the first band 63, the first and second bands 63, 64 can stick to each other without needing to turn over the first and/or second bands 63, 64 from one side to the other side thereof, thereby saving time for the user.
It is noted that, in the first embodiment, the second band 64 may include only one loop-surfaced component 642, and the first band 63 may include only one hook-surfaced component 63.

In addition, if the magnetic components 721 of the casing 71 are not respectively registered with the magnetic components 616 of the sleeve member 61, a user may rotate the casing 71 relative to the sleeve member 61 to register the magnetic components 721 of the casing 71 with the magnetic components 616 of the sleeve member 61 so that the magnetic components 721 are respectively and magnetically attracted to the magnetic components 616. By virtue of the magnetic components 721 being respectively and magnetically attracted to the magnetic components 616, the sleeve member 61 is firmly sleeved into the casing 71 and the casing 71 is prevented from moving relative to the sleeve member 61.

By virtue of the cross section of each of the guiding hole 613, the first casing passage 716 and the second casing passage 717 corresponding in shape to the cross section of the urinary catheter 2, when the urinary catheter 2 is advanced, the urinary catheter 2 is prevented from shaking, and is smoothly and precisely inserted into the urethra 113 through the external urethral orifice 114.
If a patient has the problem of urethral stricture or benign prostatic hyperplasia, the pressure sensor 3 that is adjacent to the inserting end 21 of the urinary catheter 2 may detect a pressure whose value is larger than the preset value when the inserting end 21 of the urinary catheter 2 is in the urethra 113, and thus the pressure sensor 3 generates the first pressure signal. When the processing unit 734 receives the first pressure signal from the pressure sensor 3 via the wireless communication unit 735, the processing unit 734 switches the motors 732 to the off state so the motors 732 cease to urge the conveying wheels 733 to advance the urinary catheter 2. Therefore, misuse of an incorrect urinary catheter that does not fit the urethra 113 of the patient is avoided, and the patient is prevented from getting hurt by the urinary catheter 2. If the patient does not feel uncomfortable, the forward movement button 83 may be pressed again so that the conveyor wheels 733 continue to urge the urinary catheter 2 to move forward in the urethra 113.
If a patient does not has the urethral stricture or benign prostatic hyperplasia problems, the pressure sensor 3 may not detect a pressure whose value is larger than the preset value, and thus the urinary catheterization system will not suddenly cease to urge the urinary catheter 2 to move in the urethra 113.
When the pressure sensor 3 switches from the first detected state (described hereinbefore) to the second detected state where no pressure is detected (described hereinbefore), it indicates that the inserting end 21 of the urinary catheter 2 has been inserted into a bladder 12. Consequently, the pressure sensor 3 generates the second pressure signal. When the processing unit 734 receives the second pressure signal from the pressure sensor 3 via the wireless communication unit 735, the processing unit 734 switches the motors 732 to the off state so the motors 732 cease to urge the conveying wheels 733 to advance the urinary catheter 2. The operation for insertion of the urinary catheter 2 into the bladder 12 through the penis 11 is therefore completed. At this time, the urinary catheter 2 is able to drain urine from the bladder 12, and the urine will flow from the inserting end 21 through the rear end 22 of the urinary catheter 2 into the urine collector.
A user can remove the urinary catheter 2 from the bladder 12 and the penis 11 by pressing the rearward movement button 84. When the rearward movement button 84 is pressed, the conveying assembly 7 is switched to the rearward conveying state, and the processing unit 734 controls the motors 732 to urge the conveyor wheels 733 to respectively rotate in the second rotating direction (R2) and the first rotating direction (R1) (in

In the second embodiment, the sleeve connector unit 615 has a plurality of engaging grooves 620 that are formed at the sleeve main body 610 and that are spaced apart from each other. Specifically, the engaging grooves 620 are angularly spaced apart from each other. Each of the engaging grooves 620 is configured to be L-shaped, and has a guiding portion 621 that is elongated, and an engaging portion 622 that is perpendicularly connected to one end of the guiding portion 621. The guiding portion 621 is recessed in the outer dome-shaped surface 617 and the outer surrounding surface 618. The engaging portion 622 is recessed in the outer surrounding surface 618. The casing connector unit 720 includes a plurality of engaging protrusions 723 that are formed on the inner surrounding surface 719 of the casing body 710 at intervals to protrude into the positioning groove 714, that are adjacent to the inner dome-shaped surface 718 of the casing body 710, and that respectively engage the engaging grooves 620.

In the third embodiment, the urinary catheter 2 further has a transparent section 24 that is adjacent to the rear end 22. The urinary catheterization system further includes a photodetector 4 that is mounted to the transparent section 24, that generates a light signal when detecting passage of the urine through the transparent section 24, and that is electrically coupled (e.g., wirelessly) to the wireless communication unit 735 of the conveying mechanism 73.
When the inserting end 21 of the urinary catheter 2 is inserted into the bladder 12 and when the urine in the bladder 12 flows out of the urinary catheter 2, the photodetector 4 detects passage of the urine through the transparent section 24 and generates the light signal. When the processing unit 734 receives the light signal from the photodetector 4 via the wireless communication unit 735, the processing unit 734 switches the motors 732 to the off state so that the motors 732 cease to urge the conveying wheels 733 to advance the urinary catheter 2. So far, for the third embodiment, the insertion of the urinary catheter 2 into the bladder 12 through the penis 11 has been completed.
Referring to
In the fourth embodiment, the urinary catheter 2 further has a length measurement scale 25 that is engraved on the outer catheter surface 23 along an axial direction of the urinary catheter 2, and that has a plurality of numerical values for length measurement. In this embodiment, the length measurement scale 25 is configured to have a maximum length value, for example, 30 centimeters. Since the distance between the external urethral orifice 114 and the bladder 12 of an ordinary man is arranged to be about 20 centimeters, and the distance between the rear surface 713 of the casing 71 and the guiding hole 613 of the sleeve member 61 is arranged to be 5 centimeters, when the rear surface 713 of the casing 71 is aligned with one of the numerical values between 25 cm and 30 cm of the length measurement scale 25, it means that the inserting end 21 of the urinary catheter 2 has been inserted into the bladder 12. At this time, a user may press the emergency stop button 85 so that the motors 732 cease to urge the conveying wheels 733 to advance the urinary catheter 2.
Referring to
In the fifth embodiment, the urinary catheter 2 is configured to be an indwelling urinary catheter, and includes a tube body 26 and a balloon body 27. The tube body 26 has an inserting end 261, a rear end 262, a syringe connection end 263 and an outer catheter surface 264. The inserting end 261 is adapted to be inserted into the external urethral orifice 114 of the glans 112. The rear end 262 is adapted to be connected to a urine collector (not shown). The syringe connection end 263 is adapted to be connected to a syringe (not shown). The balloon body 27 is disposed on the tube body 26, is adjacent to the inserting end 261, and is adapted to be inserted into the bladder 12. The size of the balloon body 27 increases when the balloon body 27 is filled with fluid, such as water or gas, that is injected into the syringe connection end 263 by the syringe and that flows through the tube body 26 into the balloon body 27.
The sleeve member 61 is made from a resilient material, such as polysiloxane. By virtue of the sleeve member 61 being resilient, the sleeve member 61 can be sleeved onto the glans 112 of the penis 11 in a tight fit so that the first and second bands 63, 64 may be dispensed with. This reduces the manufacturing cost and facilitates assembly of the sleeve assembly 6 onto the penis 11. It is noted that, according to operational requirements, in other modifications of the fifth embodiment, the sleeve member 61 may be connected to the first and second bands 63, 64 as in the first embodiment.
The sleeve member 61 further includes a protruding ring 623 that extends centrally through and protrudes from the dome-shaped portion 611 opposite to the tubular portion 612, that defines the guiding hole 613, and that has a chamfered surface 624 surrounding the guiding hole 613. The chamfered surface 624 directs or guides the inserting end 261 of the urinary catheter 2 to extend into the guiding hole 613 when contacting the inserting end 261 of the urinary catheter 2.
The casing 71 further has a top surface 724 that interconnects the front surface 712 and the rear surface 713, a bottom surface 725 that interconnects the front surface 712 and the rear surface 713 and that is located under the top surface 724, and an inner space 728. The positioning groove 714 is recessed in the front surface 712 and the top surface 724. The top surface 724 is recessed to form the accommodating space 715 that accommodates a portion of the conveying mechanism 73, the first casing passage 716 that spatially communicates with a rear side of the accommodating space 715 opposite to the positioning groove 714, and the second casing passage 717 that is located between the positioning groove 714 and the accommodating space 715, and that is opposite to the first casing passage 716. The tube body 26 of the urinary catheter 2 extends through the positioning groove 714, the second casing passage 717, the accommodating space 715 and the first casing passage 716. The inner space 728 spatially communicates with a bottom side of the accommodating space 715, and accommodates another portion of the conveying mechanism 73.
Referring further to
The casing 71 further has a curved supporting surface 7161 and two restraining surfaces 7162. The curved supporting surface 7161 extends from the top surface 724 of the casing 71 to the accommodating space 715 and supports the urinary catheter 2. The restraining surfaces 7162 are respectively connected to two sides of the curved supporting surface 7161 which are opposite to one another in a direction transverse to an extending direction of the curved supporting surface 7161. The restraining surfaces 7162 cooperate with the curved supporting surface 7161 to define the first casing passage 716, and are adapted for restraining movement of the urinary catheter 2 in a direction transverse to the urinary catheter 2.

Specifically, the pressing unit 739 includes a hinge 740, a frame 741 and a driven conveyor wheel 742. The hinge 740 is connected to the casing 71. The frame 741 is mounted to the hinge 740 and is rotatable relative to the casing 71 via the hinge 740. The driven conveyor wheel 742 is rotatably mounted to the frame 741 and is co-movable with the frame 741 relative to the casing 71. The frame 741 is operable to rotate relative to the casing 71 between a first position (see

Afterwards, the conveying assembly 7 is removed from the sleeve assembly 6 and the urinary catheter 2. Specifically, the frame 741 is pushed in the first pushing direction (E1) (see
It is noted that the accommodating space 715 and the first casing passage 716 are adapted to positon the urine catheter 2 when the sleeve member 61 assembled with the urine catheter 2 is positioned in the positioning groove 714. The positioning groove 714 and the second casing passage 717 are configured in such a manner that the urine catheter 2 assembled with the sleeve member 61 is allowed to move past the positioning groove 714 and the second casing passage 717 for being placed into or removed away from the accommodating space 715 and the first casing passage 716.
By virtue of the positioning groove 714, the accommodating space 715, the first casing passage 716 and the second casing passage 717, all of which are recessed at the top surface 724 to be opened at the top surface 724, and by virtue of the pressing unit 739 being movably connected the casing 71 and being operable to move towards or away from the driving conveyor wheel 738, the casing 71 can be assembled with or removed from the urinary catheter 2 without much effort.
To remove the urinary catheter 2 from the bladder 12 and the penis 11, a user has to drain the fluid in the balloon body 27 through the syringe connection end 263 of the urinary catheter 2. Next, the conveying assembly 7 is reassembled with the sleeve assembly 6 and the urinary catheter 2 as described herebefore. Afterwards, the rearward movement press portion 873 is pressed so that the conveying assembly 7 is switched to the rearward conveying state. At this time, the driving conveyor wheel 738 and the driven conveyor wheel 742 cooperatively clamp the urinary catheter 2, and the motor 732 urges the driving conveyor wheel 738 to rotate in the first rotating direction (R1) so that the urinary catheter 2 is moved rearward. Consequently, the inserting end 261 of the urinary catheter 2 is sequentially removed from the bladder 12, the urethra 113, and the external urethral orifice 114.
In summary, by virtue of the controller 8 controlling the conveying assembly 7 to advance the urinary catheter 2 to the guiding hole 613 of the sleeve member 61 through the first and second casing passages 716, 717, the urinary catheter 2, which is flexible, can be held straight and inserted precisely into the external urethral orifice 114 through the guiding hole 613. This can reduce the risk of causing discomfort to a patient due to the operation of an operator having limited experiences and training.
