DETAILED DESCRIPTION

[0020] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0021] This embodiment provides an arm model for practicing arteriovenous puncture and infusion. The device is used to achieve the purpose of disassembling and separating the arm model main body 1 by providing an arm model main body 1 and a disassembly mechanism 2.

[0022] Please refer to Figure 1 , Figure 2 and Figure 4 An arm model for practicing arteriovenous puncture and infusion comprises two arm model main bodies 1, and a disassembly mechanism 2 is commonly arranged on the left side of the two arm model main bodies 1. The disassembly mechanism 2 comprises an upper limb model 201, and the internal thread of the upper limb model 201 is connected with a fixing bolt 222. The end of the fixing bolt 222 close to the upper limb model 201 passes through the arm model main body 1 and the upper limb model 201 in sequence and extends to the outside of the arm model main body 1. The outer surface of the fixing bolt 222 is threadedly connected with a nut 223. The fixing bolt 222 is used to thread the upper limb model 201 with the fixing bolt 222, and then the nut 223 is used to cooperate with the fixing bolt 222 to fix the upper limb model 201 on the arm model main body 1, thereby playing a role in adjusting the angle of the upper limb model 201.

[0023] Please refer to Figure 1 , Figure 2 and Figure 4A muscle model 202 is arranged inside each arm model body 1, and a blood vessel model 203 is fixedly installed on the inner wall of one of the muscle models 202. The left end of the blood vessel model 203 is fixedly connected to a connecting tube 217, and the bottom end of the connecting tube 217 is fixedly connected to a connecting balloon 218. The user continuously squeezes the connecting balloon 218, so that the connecting balloon 218 cooperates with the connecting tube 217 to simulate the blood vessel pulsation of the blood vessel model 203, thereby increasing the realism during puncture.

[0024] Please refer to Figure 1 , Figure 2 and Figure 3 Two sets of connection boxes 204 are fixedly installed on the outer surface of one arm model body 1, and a placement table 210 is arranged below the arm model body 1. The outer surface of each arm model body 1 is in contact with the upper surface of the placement table 210, and two first Velcros 211 are fixedly installed on the front of the placement table 210, and two elastic bands 212 are fixedly installed on the back of the placement table 210. The front of each elastic band 212 is fixedly installed with a second Velcro 213, so that the user can pass the elastic band 212 around the arm model body 1 and then adhere the second Velcro 213 to the first Velcro 211, thereby fixing the arm model body 1, thereby avoiding the movement of the arm model body 1 during the puncture process by medical staff as much as possible.

[0025] Please refer to Figure 1 and Figure 3 The interior of each connection box 204 is slidably connected to a limiting frame 205, and a base 214 is provided under the placement table 210. Two sets of suction cups 215 are fixedly installed on the bottom surface of the base 214. The suction cups 215 are used to fix the base 214 on the desktop, so as to minimize the phenomenon of the base 214 moving on its own, thereby ensuring the stability of the base 214.

[0026] Please refer to Figure 3 Two connecting springs 206 are fixedly installed on the side close to each other of each set of limit frames 205, and the ends of each set of connecting springs 206 close to each other are fixedly connected to the side far away from each other of each set of connection boxes 204, and two telescopic rods 219 are fixedly installed on the side far away from each other of each set of connection boxes 204, and the telescopic ends of each telescopic rod 219 are fixedly connected to the outer surface of the limit frame 205. The installation of the telescopic rods 219 plays a role in limiting the moving trajectory of the limit frame 205, thereby minimizing the phenomenon that the limit frame 205 deviates from the moving trajectory during movement, thereby ensuring the stability of the movement of the limit frame 205.

[0027] Please refer to Figure 1 and Figure 4Two groups of connecting blocks 207 are fixedly installed on the outer surface of the other arm model body 1, each connecting block 207 is clamped in the inside of the connecting box 204, each limiting frame 205 is clamped in the inside of the connecting block 207, and two groups of cylinders 216 are fixedly installed on the upper surface of the base 214, and the telescopic end of each cylinder 216 is fixedly connected to the bottom surface of the placement table 210. The power provided by the cylinder 216 is used to drive the placement table 210 to move up and down, thereby adjusting the height of the placement table 210, and thus facilitating the operation of medical staff of different heights.

[0028] Please refer to Figure 3 and Figure 4 Three magnets 208 are fixedly installed on the inner wall of each arm model body 1, and three magnetic columns 209 are fixedly installed on the outer surface of each muscle model 202. The ends of the two groups of magnetic columns 209 that are away from each other are respectively in contact with the ends of the two groups of magnets 208 that are close to each other. A connecting column 220 is fixedly installed on the side away from each other of each group of limiting frames 205. A pull ring 221 is rotatably connected to the inside of each connecting column 220. The installation of the connecting column 220 and the pull ring 221 makes it convenient for medical staff to pull the limiting frame 205, thereby facilitating the medical staff to disassemble and separate the two arm model bodies 1.

[0029] Working principle: When in use, the medical staff first places the arm model body 1 on the placement table 210, and after the elastic band 212 is passed around the arm model body 1, the second Velcro 213 is adhered to the first Velcro 211, and then the medical staff turns on the cylinder 216, and uses the power provided by the cylinder 216 to drive the placement table 210 to move, so that the medical staff can adjust the height of the placement table 210 according to their own needs. After that, the medical staff continuously squeezes the connecting balloon 218, so that the gas inside the connecting balloon 218 continuously flows inside the connecting tube 217 and the blood vessel model 203, thereby simulating the vascular pulsation. After that, the medical staff performs puncture training on the arm model body 1 according to the puncture needs. When the medical staff completes the puncture, the medical staff removes the elastic band 212. The medical staff then pulls the two sets of pull rings 221 toward the side away from the arm model body 1, so that the pull rings 221 cooperate with the connecting column 220 to drive the limit frame 205 to move toward the side away from the arm model body 1, thereby causing the limit frame 205 to slide away from the connecting block 207. The medical staff then pulls the arm model body 1 connected to the connecting block 207, thereby causing the connecting block 207 to slide away from the interior of the connecting box 204, thereby separating the two arm model bodies 1 from each other. The medical staff then pulls the muscle model 202 toward the side away from the arm model body 1, thereby separating the magnet 208 and the magnetic column 209 from each other, thereby removing the muscle model 202 from the arm model body 1, making it convenient for the medical staff to observe the insertion angle of the puncture needle, thereby facilitating the medical staff to correct the phenomenon of irregular insertion angle in a timely manner.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
