[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4 , the present utility model provides a technical solution: a urinary catheter inserter, including a first urinary catheter insertion tube body 1 and a second urinary catheter insertion tube body 2. The second urinary catheter insertion tube body 2 is fitted and installed on the outer side of the first urinary catheter insertion tube body 1. A positioning annular groove 3 is provided on the outer surface of the top ends of the first urinary catheter insertion tube body 1 and the second urinary catheter insertion tube body 2. Anti-slip strips 4 are installed on the inner walls of the first urinary catheter insertion tube body 1 and the second urinary catheter insertion tube body 2. A positioning ring body 5 is sleeved and installed outside the positioning annular groove 3. A connecting pull rod 6 is installed inside the first urinary catheter insertion tube body 1 and the second urinary catheter insertion tube body 2. An operation joint 7 is provided at the top end of the connecting pull rod 6. A central positioning circular plate 8 is installed at the bottom end of the connecting pull rod 6, and the central positioning circular plate 8 is located inside the first urinary catheter insertion tube body 1 and the second urinary catheter insertion tube body 2. An auxiliary insertion rod 9 is provided at the center of the bottom surface of the central positioning circular plate 8, and the auxiliary insertion rod 9 passes through the bottom outlets of the first urinary catheter insertion tube body 1 and the second urinary catheter insertion tube body 2.

[0022] The structures of the first urinary catheter insertion tube body 1 and the second urinary catheter insertion tube body 2 are the same. The diameters of the top ends of the first urinary catheter insertion tube body 1 and the second urinary catheter insertion tube body 2 are larger than the middle of the bottom ends of the first urinary catheter insertion tube body 1 and the second urinary catheter insertion tube body 2. And the first urinary catheter insertion tube body 1 and the second urinary catheter insertion tube body 2 form a tube body structure, so that the first urinary catheter insertion tube body 1 and the second urinary catheter insertion tube body 2 form a tube body, which is beneficial to the subsequent insertion work of the bottom ends of the first urinary catheter insertion tube body 1 and the second urinary catheter insertion tube body 2.

[0023] The positioning ring body 5 is provided with an opening, and the connection mode of the positioning ring body 5 with the first urinary catheter insertion tube body 1 and the second urinary catheter insertion tube body 2 through the positioning annular groove 3 is snap connection. Through the snap connection of the positioning ring body 5 and the positioning annular groove 3, the combination of the first urinary catheter insertion tube body 1 and the second urinary catheter insertion tube body 2 can be positioned and kept stable. And subsequently, the positioning ring body 5 can be separated from the urinary catheter through the opening.

[0024] The connecting rod 6, the operating joint 7 and the central positioning circular plate 8 are integrally structured. And the connection mode of the central positioning circular plate 8 with the first urinary catheter insertion tube body 1 is rotational sliding, which enables the connecting rod 6 and the operating joint 7 to drive the central positioning circular plate 8 to slide into the combination, facilitating central positioning and avoiding shaking.

[0025] The connection mode of the central positioning circular plate 8 with the anti-slip strip 4 is extrusion fitting. And the top end of the anti-slip strip 4 is inclined. And the anti-slip strips 4 are equally angularly distributed on the first urinary catheter insertion tube body 1 and the second urinary catheter insertion tube body 2, facilitating the extrusion of the central positioning circular plate 8 with the anti-slip strip 4 after sliding in, improving the stability of the combination and avoiding shaking.

[0026] The auxiliary insertion rod 9 and the central positioning circular plate 8 are integrally structured. And the connection mode of the auxiliary insertion rod 9 with the first urinary catheter insertion tube body 1 and the second urinary catheter insertion tube body 2 is sliding fitting. And the bottom end of the auxiliary insertion rod 9 is provided with a rounded structure. The auxiliary insertion rod 9 can pass through the first urinary catheter insertion tube body 1 and the second urinary catheter insertion tube body 2. According to the bottom end of the auxiliary insertion rod 9, the insertion operation can be quickly carried out.

[0027] Working principle: According to Figures 1-4, first, the first urinary catheter insertion tube body 1 and the second urinary catheter insertion tube body 2 can be held by hand to perform auxiliary work. The first urinary catheter insertion tube body 1 and the second urinary catheter insertion tube body 2 can drive the auxiliary insertion rod 9 to move, so that the auxiliary insertion rod 9 inserts into the urinary orifice, and can assist the bottom ends of the first urinary catheter insertion tube body 1 and the second urinary catheter insertion tube body 2 to insert. Subsequently, the operation joint 7 and the connection pull rod 6 are pulled. The connection pull rod 6 pulls the central positioning circular plate 8. The central positioning circular plate 8 slides and separates inside the first urinary catheter insertion tube body 1 and the second urinary catheter insertion tube body 2. The central positioning circular plate 8 separates from the anti-slip strip 4. At the same time, the central positioning circular plate 8 drives the auxiliary insertion rod 9 to slide and separate from the first urinary catheter insertion tube body 1 and the second urinary catheter insertion tube body 2. Subsequently, the urinary catheter can be passed through the first urinary catheter insertion tube body 1 and the second urinary catheter insertion tube body 2 and then inserted into the urinary orifice. Then, the first urinary catheter insertion tube body 1 and the second urinary catheter insertion tube body 2 can be pulled, so that the first urinary catheter insertion tube body 1 and the second urinary catheter insertion tube body 2 separate from the urinary orifice. At the same time, the positioning ring body 5 is pulled, and the positioning ring body 5 separates from the positioning annular groove 3, which facilitates the separation of the first urinary catheter insertion tube body 1 and the second urinary catheter insertion tube body 2, and thus the outer side of the urinary catheter separates. At the same time, the positioning ring body 5 separates from the urinary catheter through the opening. The above is the working process of the entire device, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
