Description

Technical Field

[0001] The invention belongs to the field of medical puncture guidance, and in particular relates to a puncture positioning guidance device for training. Background Art

[0002] As the number of patients with uremia increases, the demand for hemodialysis treatment is also growing. In hemodialysis treatment, arteriovenous fistula is an important channel connecting the patient's artery and vein, which is used to draw blood out of the body for purification and then return to the body. Due to the frequency of dialysis treatment, the fistula blood vessels need to be punctured frequently, which causes great damage and pressure to the patient's blood vessels. Therefore, the use of reasonable puncture methods, such as rope ladder puncture, is of great significance to reduce complications and protect the patient's lifeline.

[0003] The rope ladder puncture method avoids repeated damage to the same blood vessels in a short period of time by dispersing the puncture points, providing sufficient healing time for the blood vessels, thereby effectively reducing the occurrence of complications such as pseudoaneurysms, thrombosis, and infection. With the increasing emphasis on humanistic care in the medical field, it has become undesirable to use patients as direct practice objects for medical operations. At the same time, with the rapid development of simulation technology teaching, the demand for innovation in teaching tools and methods in medical education is also increasing. Especially for the training of young nurses, they need a visual and highly operable simulation model for repeated practice to improve their professional skills and ability to deal with complex situations.

[0004] In hemodialysis treatment, arteriovenous fistula rope ladder puncture is a crucial skill. Since this puncture method involves direct manipulation of blood vessels, it places extremely high demands on nurses' operating skills and experience. However, traditional training methods often fail to provide sufficient practice opportunities, resulting in many challenges that nurses may face in actual operations. In addition, general puncture models cannot adjust the position of blood vessels in real time, cannot simulate more puncture sites, and cannot provide more diverse training.

[0005] Based on this, the applicant considered designing a puncture positioning guide device for training. Summary of the invention

[0006] In view of the above problems, the present invention provides a puncture positioning guide device for training that overcomes the above problems or at least partially solves the above problems. The technical solution is as follows:

[0007] A puncture positioning and guiding device for training comprises an arm model, a fixed platform, a first movable pad, a first fistula body, a first simulated blood vessel and a rotating mechanism, wherein the fixed platform is a rectangular platform with a length, the fixed platform is installed in the arm model, and the length direction of the fixed platform is consistent with the length direction of the arm model, a movable surface is provided on the top surface of the fixed platform, and the first movable pad is movably installed on the movable surface, there are two transmission mechanisms, which are respectively arranged at two ends in the length direction of the fixed platform, the first fistula body is installed on the first movable pad, the first fistula body comprises a first end and a second end opposite to each other, the first simulated blood vessel is wound along the top and bottom surfaces of the fixed platform, and the winding direction is consistent with the length direction of the fixed platform, and at the same time, the two ends of the first simulated blood vessel respectively pass through and are wrapped around the two transmission mechanisms, and are respectively connected with the first end and the second end of the first fistula body, and the transmission mechanism is used to drive the first simulated blood vessel and the first fistula body to move.

[0008] Compared with the prior art, the puncture positioning guide device for training of the present invention has the following advantages:

[0009] By setting up the arm model, fixed platform, first movable pad, first fistula body, first simulated blood vessel and rotating mechanism, the positions of the first fistula body and the first simulated blood vessel can be adjusted in real time through the first movable pad to simulate more puncture positions and provide more diversified training. The structure is relatively simple and the movement is relatively convenient.

[0010] The above-mentioned puncture positioning and guiding device for training has the advantages of simple structure and easy implementation, is suitable for installation and use in existing vascular puncture training, and has low cost of use, which can improve benefits.

[0032] In this way, by providing a plurality of magnetic points 220 and plate-shaped magnets 311 , the first movable pad 310 can be better fixed on the movable surface 210 by magnetic attraction.

[0033] In this embodiment, Figure 1-6 As shown, a permanent magnet is disposed in each of the magnetic attraction points 220 .
