Referring to FIG. 1 , FIG. 4 and FIG. 5 , the step S1 includes the following sub-steps: setting the sleeve, and wrapping and fixing the first strap and the second strap. In the sub-step of sheathing the sleeve, the sleeve 61 is sheathed on the glans penis 112 of the patient so that the glans penis 112 is inserted into the accommodating groove 614 . Since the socket assembly 6 is a portable structure, the user can The sleeve 61 can be easily and quickly set on the glans penis 112 , and the guiding through hole 613 can be accurately aligned with the urethral opening 114 . Since the hollow casing 611 is hemispherical and matches the shape of the glans head 112 , the fit of the sleeve 61 when being sleeved on the glans head 112 can be effectively improved, so as to reduce the shaking of the sleeve 61 relative to the glans head 112 .

Then, the sub-step of winding and fixing the first strap and the second strap is performed, for example, firstly, the first strap 63 is wound around the penis shaft 111 along the axial direction of the penis shaft 111 and tightened. Then, the second strap 64 is wound around the penis shaft 111 and the first strap 63 along the axial direction of the penis shaft 111 , and is tightened around the penis shaft 111 and the first strap 63 . Afterwards, one of the fleece pieces 642 of the second belt 64 is fastened to the corresponding hook piece 632 of the first belt 63, so that the second belt 64 and the first belt 63 can be connected together. are firmly fixed together, so that the socket assembly 6 can be firmly fixed on the penis 11 .

The penis shaft 111 is wound by the first strap 63 and the second strap 64 , and the hook surface 632 and the hair surface of the devil felt are passed between the first strap 63 and the second strap 64 The way that the pieces 642 are glued together can overcome the limitation on assembly caused by the different outer diameter and length of the penis shaft 111 of different patients, so that the user can adjust the penis shaft 111 according to the outer diameter and length of the patient's penis shaft 111 The length and tightness of the wrapping of the first strap 63 and the second strap 64 . Furthermore, the hook surface pieces 632 of the first belt 63 are respectively arranged on both sides of the first belt body 631, and the wool surface pieces 642 of the second belt 64 are respectively arranged on the second belt body 641 on both sides so that the first A strap 63 or/and the second strap 64 can be fastened together through the hook surface sheet 632 and the fur surface sheet 642 at the corresponding positions without additionally turning over. Thereby, the convenience of assembling the first strap 63 and the second strap 64 can be improved.

It should be noted that, the number of the hook surface pieces 632 and the number of the hair surface pieces 642 in the first embodiment can also be one, but not limited to two.

Referring to FIGS. 4 , 6 and 7 , in step S2 , the positioning groove 714 of the housing 71 of the conveying assembly 7 is first aligned with the sleeve 61 of the socket assembly 6 , and then the housing 71 is sleeved on the sleeve 61 so that the sleeve 61 is inserted into the positioning groove 714 . When the outer arc surface 617 of the sleeve 61 contacts and blocks the inner arc surface 718 of the casing 71 , the casing 71 can no longer move relative to the sleeve 61 . Since the first magnets 616 are respectively accommodated in the first grooves 619 and are flush with the outer arc surface 617 , and the second magnets 721 are respectively accommodated in the second grooves 722 and It is flush with the inner arc surface 718 , so the outer arc surface 617 can contact and block the inner arc surface 718 in a surface contact manner, so as to enhance the blocking effect of the housing 71 . Furthermore, by the outer arc surface 617 and the outer peripheral surface 618 respectively abutting on the inner arc surface 718 and the inner peripheral surface 719 , the casing 71 can be prevented from being relative to the sleeve after being sleeved on the sleeve 61 . The barrel 61 is shaken so that the second guide hole 717 can be accurately aligned with the guide through hole 613 .

When the second magnets 721 of the casing 71 are aligned with the first magnets 616 of the sleeve 61 respectively, the second magnets 721 magnetically attract the first magnets 616 respectively, thereby making the casing 71 can be firmly fixed on the sleeve 61 . if the When the positions of the second magnets 721 are not aligned with the positions of the first magnets 616 , the housing 71 is rotated relative to the sleeve 61 to adjust the positions of the second magnets 721 . When the housing 71 can no longer rotate, it means that the second magnets 721 are aligned and magnetically attract the first magnets 616 respectively.

4 and 8, in step S3, the insertion end 21 of the urinary catheter 2 is inserted into the first guide hole 716 through the rear end 713 of the housing 71 and passed through the first guide hole 716 penetrates into the accommodating space 715 , so that the urinary catheter 2 is inserted between the conveying wheels 733 and clamped by the conveying wheels 733 .

Referring to FIG. 1 , FIG. 3 , FIG. 4 and FIG. 9 , in step S4 , first, the user switches the conveying assembly 7 to the power-on state by pressing the power-on button 81 of the controller 8 . Next, the user presses the forward button 83 to switch the delivery assembly 7 to the forward delivery state. At this time, the processor 734 controls the motors 732 to turn on, so that the motors 732 drive the conveying wheels 733 to rotate along the first rotation direction R1 and the second rotation direction R2 respectively. During the reverse rotation of the conveying wheels 733, the catheter 2 is driven to move along a forward direction D1, so that the insertion end 21 of the catheter 2 passes through the second guide hole 717, the guide The through hole 613 and the urethral opening 114 penetrate into the urethra 113 .

Since the guide through hole 613 , the first guide hole 716 and the second guide hole 717 are all circular and the shape matches the shape of the urinary catheter 2 , the guide can be smoothly guided. The urinary catheter 2 is moved to reduce the shaking of the urinary catheter 2 during the movement The urethral opening 114 can be inserted into the urethra 113 straightly and accurately.

If the patient has problems such as urethral stenosis or prostate hypertrophy, and the pressure sensed by the pressure sensor 3 in the urethra 113 exceeds the preset value, the pressure sensor 3 generates the sensing signal. When the processor 734 receives the sensing signal generated by the pressure sensor 3 through the wireless communication module 735, the processor 734 turns off the motors 732, so that the conveying wheels 733 stop conveying the guide Urinary catheter 2 moves. Thereby, it can be avoided that the patient uses the urinary catheter 2 with an inappropriate size or the urinary catheter 2 causes damage to the patient's urethra 113 . If the patient does not feel discomfort, the user can press the advancing button 83 again to make the conveying wheels 733 continue to drive the catheter 2 to move in the urethra 113 along the advancing direction D1.

If the patient does not have the aforementioned problems such as urethral stricture or prostate hypertrophy, the movement of the urinary catheter 2 in the urethra 113 will not suddenly stop moving.
