Description
Technical Field
[0001] This utility model relates to the field of human arm models, and in particular to a human arm model for practical training. Background Technology
[0002] In medical education, human arm models are an indispensable core teaching tool for medical students' practical training. They can highly simulate the anatomical structure, joint mobility, and surface characteristics of a human arm, providing medical students with repeated training scenarios for practical skills such as intravenous puncture, intramuscular injection, wound suturing, and blood pressure measurement. This helps learners accumulate clinical experience without real human subjects, reducing medical risks and improving practical proficiency and accuracy. Whether for basic medical skills training or specialized training in nursing and surgical procedures, human arm models, with their reusability and lack of ethical restrictions, have become a key vehicle bridging theory and practice in medical education.
[0003] During practical training, to ensure the stability and accuracy of operations, the human arm model usually needs to be fixed in a specific position to avoid operational errors or poor skill training results due to model displacement. However, traditional human arm model designs generally lack dedicated fixing structures. During training, users have to rely on external straps, clamps, or supports for fixation, which is cumbersome and time-consuming. This method of fixation, which relies on external tools, increases the complexity of training preparation and is difficult to meet the needs of practical training. Utility Model Content
[0004] The main purpose of this invention is to provide a human arm model for practical training, which can effectively solve the problems in the background technology.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A training human arm model includes an arm model body. An installation tube is fixedly installed inside the arm model body. A suction cup assembly is inserted into the lower side of the installation tube. The suction cup assembly consists of a support rod, a suction cup, and an installation block. The suction cup is fixedly installed at the lower end of the support rod, and the installation block is fixedly installed at the upper end of the support rod. Two fixing members are symmetrically installed on the installation block, both located inside the installation tube. Each fixing member consists of a fixing block, a connecting plate, an anti-detachment plate, and a return spring. The connecting plate is fixedly installed at the lower end of the fixing block, the anti-detachment plate is fixedly installed at the lower end of the connecting plate, and the return spring is fixedly installed at the outer end of the anti-detachment plate. A limiting member is inserted inside the installation tube between the two fixing blocks on the two fixing members. The limiting member consists of a base column, a handle plate, and an insert plate. The handle plate is fixedly installed at the upper end of the base column, and the insert plate is fixedly installed at the lower end of the base column.
[0006] Preferably, the main body of the arm model has mounting through holes.
[0007] Preferably, the mounting tube is fixedly inserted into the mounting through hole, and two fixing slots are symmetrically opened on the upper inner wall of the mounting tube.
[0008] Preferably, the support rod and mounting block on the suction cup assembly are inserted into the mounting tube, the mounting suction cup is located below the mounting tube, the mounting block has an anti-detachment guide groove, and the upper end of the mounting block has a connecting guide groove, the connecting guide groove and the anti-detachment guide groove are interconnected.
[0009] Preferably, the insert plate on the limiting member is inserted between the two fixing blocks on the fixing member.
[0010] Preferably, the connecting plate on the fixing member is slidably installed in the connecting guide groove, the anti-detachment plate is slidably installed in the anti-detachment guide groove, the reset spring is located in the anti-detachment guide groove, the fixing block is located at the upper end of the mounting block, and the fixing block is embedded in the fixing slot under the push of the insert plate.
[0011] Compared with the prior art, the present invention has the following beneficial effects: By setting an installation tube inside the main body of the arm model, and installing a suction cup assembly consisting of a support rod, a suction cup, and an installation block inside the installation tube, and setting a fixing component consisting of a fixing block, a connecting plate, an anti-detachment plate, and a return spring on the suction cup assembly, and setting a limiting component consisting of a base column, a handle plate, and an insert plate between the two fixing components, the suction cup assembly can be attached to a flat worktable, thus stably fixing the main body of the arm model on the worktable, avoiding model displacement during training and affecting operational accuracy, and eliminating the need for external straps, clamps, or other auxiliary tools, simplifying the training preparation process and improving training efficiency. The fixing component, together with the limiting component, facilitates the assembly and disassembly of the suction cup assembly and the installation tube. The insert plate pushes the fixing block into the fixing slot of the installation tube to achieve a stable fixation of the suction cup assembly and the installation tube. After pulling out the limiting component, the return spring can drive the fixing block to disengage from the fixing slot, thus releasing the fixation of the suction cup assembly and the installation tube, thereby facilitating disassembly and maintenance. At the same time, the overall structure design is compact and does not affect the simulation of the model's anatomical structure and its use in training operations, effectively improving the convenience and practicality of medical training.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0015] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, a training human arm model includes an arm model body 1. An installation tube 2 is fixedly installed inside the arm model body 1. A suction cup assembly 3 is inserted into the lower side of the installation tube 2. The suction cup assembly 3 consists of a support rod 8, a suction cup 9, and an installation block 10. The suction cup 9 is fixedly installed at the lower end of the support rod 8, and the installation block 10 is fixedly installed at the upper end of the support rod 8. Two fixing parts 4 are symmetrically installed on the installation block 10, and the fixing parts 4 are located inside the installation tube 2. The fixing parts 4 consist of a fixing block 13, a connecting plate 14, an anti-detachment plate 15, and a return spring 16. The connecting plate 14 is fixedly installed at the lower end of the fixing block 13, the anti-detachment plate 15 is fixedly installed at the lower end of the connecting plate 14, and the return spring 16 is fixedly installed at the outer end of the anti-detachment plate 15. A limiting member 5 is inserted into the mounting tube 2 between the two fixing blocks 13 on the two fixing members 4. The limiting member 5 consists of a base column 17, a handle plate 18, and an insert plate 19. The handle plate 18 is fixedly installed at the upper end of the base column 17, and the insert plate 19 is fixedly installed at the lower end of the base column 17. By setting the mounting tube 2 inside the arm model body 1, and setting the support rod 8 and mounting suction inside the mounting tube 2, a limiting member 5 is installed. The suction cup assembly 3, consisting of a plate 9 and a mounting block 10, has a fixing member 4 consisting of a fixing block 13, a connecting plate 14, an anti-detachment plate 15, and a return spring 16. A limiting member 5 consisting of a base column 17, a handle plate 18, and an insert plate 19 is placed between the two fixing members 4. The suction cup assembly 3 can adhere to a flat worktable, thus stably fixing the main body 1 of the arm model to the worktable, preventing model displacement during training and ensuring operational accuracy. Furthermore, it eliminates the need for external straps, clamps, or other auxiliary tools, simplifying the training preparation process and improving efficiency. Training efficiency; the fixing part 4, together with the limiting part 5, can facilitate the assembly and disassembly of the suction cup assembly 3 and the mounting tube 2. The fixing block 13 is pushed into the fixing slot 7 of the mounting tube 2 by the insert plate 19, so as to achieve a stable fixation between the suction cup assembly 3 and the mounting tube 2. After the limiting part 5 is pulled out, the return spring 16 can drive the fixing block 13 to disengage from the fixing slot 7, thereby releasing the fixation between the suction cup assembly 3 and the mounting tube 2, which facilitates disassembly and maintenance. At the same time, the overall structure is compact and does not affect the simulation of the anatomical structure of the model itself and the use of training operations, effectively improving the convenience and practicality of medical training.
[0016] Specifically, the main body 1 of the arm model has a mounting through hole 6, and the mounting tube 2 is fixedly inserted into the mounting through hole 6. Two fixing slots 7 are symmetrically opened on the upper inner wall of the mounting tube 2. The support rod 8 and the mounting block 10 on the suction cup assembly 3 are inserted into the mounting tube 2. The mounting suction cup 9 is located below the mounting tube 2. The mounting block 10 has an anti-detachment guide rail groove 11. The upper end of the mounting block 10 has a connecting guide rail groove 12, which is connected to the anti-detachment guide rail groove 11. The insert plate 19 on the limiting member 5 is inserted between the two fixing blocks 13 on the fixing member 4. The connecting plate 14 on the fixing member 4 is slidably installed in the connecting guide rail groove 12 to prevent detachment. Plate 15 is slidably installed in anti-detachment guide groove 11, return spring 16 is located in anti-detachment guide groove 11, fixing block 13 is located at the upper end of mounting block 10, and fixing block 13 is embedded in fixing slot 7 under the push of insert plate 19. Mounting tube 2, suction cup assembly 3, fixing part 4, and limiting part 5 are pre-installed on the arm model body 1. When using this training human arm model, first place the arm model body 1 on a flat workbench, make the mounting suction cup 9 of suction cup assembly 3 closely adhere to the workbench surface and press it to ensure that the mounting suction cup 9 is firmly attached to the workbench. At this time, the fixing of the arm model body 1 on the workbench is completed, and then static installation can be performed. After training in procedures such as vein puncture and intramuscular injection, the suction cup 9 can be separated from the workbench after the training is completed. When disassembling and maintaining the suction cup assembly 3, fixing component 4, and limiting component 5, or storing them separately, pull upwards the handle 18 of the limiting component 5 to pull the base column 17 out of the installation tube 2, and pull the insert plate 19 out between the two fixing blocks 13 on the two fixing components 4. At this time, the return spring 16 of the fixing component 4 returns to its elastic deformation, pushing the anti-detachment plate 15, connecting plate 14, and fixing block 13 inwards, causing the fixing block 13 to disengage from the fixing slot 7. Then, pull downwards the suction cup assembly 3 and fixing component 4 to remove them from the mounting tube. Remove the suction cup assembly 3, fixing component 4, and limiting component 5 from the mounting tube 2. Then, the suction cup assembly 3, fixing component 4, and limiting component 5 can be maintained or stored separately. When installing the suction cup assembly 3, fixing component 4, and limiting component 5 into the mounting tube 2, first insert the support rod 8, mounting block 10, and fixing component 4 of the suction cup assembly 3 into the mounting tube 2, while aligning the fixing block 13 on the fixing component 4 with the fixing slot 7. Finally, insert the insert plate 19 of the limiting component 5 between the two fixing blocks 13. At this time, under the push of the insert plate 19, the fixing block 13 is embedded into the fixing slot 7. At this time, the anti-detachment plate 15 will compress the return spring 16, thereby completing the assembly of the suction cup assembly 3, fixing component 4, and limiting component 5 into the mounting tube 2.
[0017] It should be noted that the mounting through hole 6 is located on the main body 1 of the arm model in a position that does not affect training operations such as intravenous puncture, intramuscular injection, wound suturing, and blood pressure measurement. This ensures the installation requirements of the fixed structure without interfering with the normal training use of the model.
[0018] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
