Description

Teaching aids for difficult vascular puncture

This creative department is related to teaching tools, especially a kind of difficult vascular puncture teaching aid.

Clinical medical education is patient-oriented life education. In view of the increase in clinical dialysis patients and the increase in invasive treatments such as hemodialysis and dialysis, patient safety and patient rights are more important. Medical staff's correct judgment of clinical work and technical operations required to be completed in the first place, As an important factor in patient's life protection, the training of medical related personnel through simulation implementation can promote and implement medical services centered on patient safety and ethical considerations.

Due to the diversity of blood vessels in clinical dialysis patients, including upstream and downstream stenosis, distortion, pseudoaneurysm, obstruction, small blood vessels and other blood vessel variations, if not handled properly, it will not only increase patient discomfort, but also cause serious medical disputes . Therefore, how to extend the puncture training for difficult blood vessels during the training of medical-related personnel should be touched on in clinical education.

Therefore, the main purpose of this work is to provide a teaching tool for difficult blood vessel puncture, which is to reproduce the clinical difficult blood vessels as a teaching aid, as a teaching tool for the education and training of medical personnel.

The reason is that in order to achieve the above purpose, the vascular puncture teaching aid provided by this creation includes a vascular component with a body part made of a material that can be punctured, and a vascular channel is formed in the body The inside of the part; wherein, the vascular channel is an arterial blood vessel, a venous blood vessel, an arteriovenous coil, or a difficult arteriovenous coil with vascular variation.

The vascular variations of the difficult arteriovenous tube are upstream stenosis, downstream stenosis, twisting, pseudoaneurysm, thrombosis, obstruction, or small blood vessels.

In order to provide a more complete education and training for medical personnel, the difficult vascular puncture teaching aid is a human body part such as a human arm that is often used as a puncture site, so that the difficult vascular puncture teaching aid further includes an arm component in structure, which has The contour shape of the arm or the palm is similar; a fitting hole is recessed on the arm element; and the blood vessel element is combined with the arm element by being embedded in the fitting hole.

In order to provide a communication channel between the blood vessel element and the arm element for blood flow detection, the blood vessel element can further include two openings, which are arranged on both sides of the body and communicate with the blood vessel channel Communication, and the arm element has a first channel and a second channel connected in series with each of the openings.

First of all, please refer to FIG. 1 to FIG. 4, the difficult blood vessel puncture teaching aid (10) provided in the first preferred embodiment of the present invention mainly includes an arm element (20) and a fitting hole ( 30) and a vascular element (40).

The arm element (20) has a shape similar to the upper limb of the human body, including upper arm, lower arm and palm parts, and the fitting hole (30) is recessed on the arm element (20), wherein the arm The element (20) further includes a tubular first channel (not shown in the figure) and a second channel (not shown in the figure) for forming an arterial vascular channel and a venous vascular channel in the limb similar to the human upper limb The number is not limited to a single one, and can be increased or decreased according to the actual training needs. In this embodiment, the number of the first channel and the second channel are two, and each is in the fitting hole ( 30) Channel openings are formed on both sides of the hole wall.

The vascular element (40) is integrally formed by 3D printing from a suitable material, and can be repeatedly punctured without the risk of leakage. As for the structure, the vascular element (40) has a shape The upper part and the fitting hole (30) are complementary body parts (41), a vascular channel (42) with an arteriovenous coil as an existing shape is formed inside the body part (41), and two openings (43) ) Are provided on both sides of the body (41) and are in communication with the vascular channel (42).

In use, the vascular element (40) is inserted into the fitting hole (30) with the body (41), and each opening (43) is respectively connected with the corresponding first channel and second channel Connect and connect to fully reproduce the distribution of blood vessels in the upper limbs for puncture training.

It should be explained here that although in the first preferred embodiment disclosed above, the shape of the vascular channel is similar to that of the arteriovenous tube, the actual use of this creation is not limited to this, and Vascular information that can be obtained clinically, for example, through the establishment of different vascular computer models of CT images of clinical patients, including arterial blood vessels, venous blood vessels, arteriovenous shunt tubes, mutated blood vessels, or vascular shunt tubes of mutated blood vessels. Difficult blood vessel models, such as the vascular channel (42a) of the variant blood vessel of the vascular component (40a) shown in FIGS. 5 and 6, or the vascular channel of the arteriovenous coil of the vascular component (40b) shown in FIGS. 7 and 8. (42b), etc., can be made into the vascular component through 3D printing, to reproduce the clinical vascular appearance, so that the education and training of medical personnel can be more in line with clinical practice, so that patients can get better Care.
