Technical Field

[0001] The utility model relates to the technical field of medical appliances, and particularly relates to a simulation radial artery puncture practice device. Background Art

[0002] The radial artery is one of the terminal branches of the brachial artery, slightly smaller than the ulnar artery. The radial artery is a common part for clinical palpation of the pulse, and its pulsation can be felt above the inner side of the radial styloid process. It is mainly responsible for the blood supply of the upper limb, participates in the formation of the arterial network of the elbow joint, and maintains the normal physiological functions of the human body. If the radial artery is diseased, bleeding, pain, skin changes, etc. may occur.

[0003] In clinical medicine, radial artery puncture has relatively high requirements for operators and requires a large amount of pre-simulation practice before starting the operation. In the prior art, puncture practice is generally carried out through a soft limb practice mold. This method has instability. Firstly, the mold is not effectively fixed. Secondly, the mold is not placed in an appropriate position and cannot simulate the real operation scenario.

[0004] Therefore, it is very necessary to invent a simulation radial artery puncture practice device to solve the above problems. Content of the Utility Model

The elastic binding strap is inserted into this gap, and the elastic binding strap has left and right ends that are far away from each other.

[0013] Preferably, the left and right ends of the elastic binding strap extend out of the notch, and the left and right ends of the elastic binding strap extend to directly above the horizontal section. A hook surface of Velcro is provided at the left end of the elastic binding strap, and a fuzzy surface of Velcro is provided at the right end of the elastic binding strap. The left and right ends of the elastic binding strap can be attached and connected into one body through the cooperation of the hook surface and the fuzzy surface of Velcro.

The bottom surface of the needle groove is an inclined surface, and the bottom surface of the needle groove gradually inclines away from the pull handle. In order to facilitate taking out the needle, the bottom surface of the needle groove is set as an inclined surface. As shown in the figure, when in use, the thinner needle can be felt out along the bottom surface of the needle groove, which is convenient to use;

The height of the second end 5 is higher than that of the first end 4, and the outer side surfaces of the first end 4 and the second end 5 are both hemispherical surfaces.

[0032] In order to adapt to the shape of the practice mold, the bending direction of the surface of the arc surface 3 is downward. It is convenient for the practice mold to be correctly placed on the supporting main body 1 and the supporting sub-body 2. Specifically, the hand part of the practice mold (not shown) is placed on the arc surface 3 of the supporting main body 1 to form a fit with the arc surface 3, and the forearm part of the practice mold is placed on the supporting sub-body 2 to obtain horizontal support. The horizontal section 6 and the vertical section 7 are of an integrally formed structure.

[0033] For simulating the real pressurization step and for stability purposes, an elastic strap 9 is provided inside the notch 8. A cross bracket 10 is provided on the top surface of the notch 8. There is a gap between the cross bracket 10 and the top surface of the notch 8. The elastic strap 9 is inserted into this gap, and the elastic strap 9 has left and right ends that are far away from each other. The left and right ends of the elastic strap 9 extend out of the notch 8, and the left and right ends of the elastic strap 9 extend to directly above the horizontal section 6.

[0035] Embodiment 2

[0036] The rest of the structure remains unchanged. To improve the adaptability of the overall structure, the distance between the supporting main body 1 and the supporting auxiliary body 2 is set to be adjustable by pulling.
