[0027] The present embodiment provides a blood vessel puncture angle guiding model, as shown in Figures 1 to 3As shown, it comprises a simulated blood vessel 1, an angle guiding assembly 2 and a blood vessel depth adjusting assembly 3, the blood vessel depth adjusting assembly 3 comprises a multi-layer simulated skin tissue 32, the simulated blood vessel 1 is arranged in the simulated skin tissue 32, and the angle guiding assembly 2 is located above the simulated skin tissue 32. The simulated blood vessel 1 and the simulated skin tissue 32 simulate the blood vessel and skin environment of the human body, providing more realistic tactile and visual feedback for medical training. The angle guiding assembly 2 ensures the accuracy of the angle during puncture, and the blood vessel depth adjusting assembly 3 makes the depth of the simulated blood vessel 1 adjustable to adapt to different training needs. The simulated blood vessel 1 is filled with red liquid, which facilitates observation of blood return during simulated puncture to determine the success of puncture. The simulated skin tissue 32 is made of transparent flexible silicone material (white jelly); the angle guiding assembly 2 is arranged in close contact with the simulated skin tissue 32.

[0028] The angle guiding assembly 2 comprises an angle guiding plate 21 and a telescopic rod 22, and the angle guiding plate 21 is connected to the telescopic rod 22. The telescopic rod 22 is used to adjust the height of the angle guiding plate 21, and the angle guiding plate 21 is adjusted to be in close contact with the upper surface of the simulated skin tissue 32, so as to ensure the accuracy of angle adjustment as much as possible.

[0029] The plate body 211 has an angle scale 2111, and the baseline of the angle scale is parallel to the simulated skin tissue. The angle scale 2111 provides an accurate angle reference, and the trainer can adjust the pointer 212 to the desired angle position according to the angle scale 2111, so as to ensure the consistency of the angle of each puncture. The baseline of the angle scale is parallel to the simulated skin tissue to ensure the accuracy of angle adjustment. This can better simulate clinical operation and improve the success rate of puncture and the quality of training.

[0030] The pointer 212 is provided with a ray indicator 2121. The ray indicator 2121 indicates the puncture direction by light or laser, so that the trainer can more intuitively see the puncture angle and direction. This design can significantly improve the visibility and accuracy of operation and reduce errors.

[0031] The blood vessel depth adjusting assembly 3 comprises a plurality of fixed rods 31 arranged in parallel and a multi-layer simulated skin tissue 32, and each layer of the simulated skin tissue 32 is detachably mounted on the fixed rod 31. Through the parallel arrangement of the fixed rods 31, the layers of the simulated skin tissue 32 can be stably fixed and easily detached and replaced. Different layers of the simulated skin tissue 32 can adjust the depth of the simulated blood vessel 1, simulate the blood vessel conditions of different patients, and improve the flexibility and practicality of training.

[0032] The simulated skin tissue 32 is provided with a limiting hole, and the fixing rod 31 penetrates into the corresponding limiting hole to limit the simulated skin tissue 32. The limiting hole ensures the accurate position of the simulated skin tissue 32 on the fixing rod 31, prevents the skin layer from sliding or shifting during the training process, and thus maintains the stability and consistency of the training environment. This design ensures that the relative position of the simulated skin tissue 32 and the simulated blood vessel 1 is fixed, so that the conditions of each training are consistent, facilitating repetitive training and effect evaluation.

[0033] Specific application cases:

[0034] In medical training, precise venipuncture skills are one of the basic skills required for medical personnel. In order to improve the training effect and the operation level of students, the model simulates the real blood vessel and skin environment, combines angle guidance and depth adjustment functions, and provides systematic training for students.

[0035] Specific use method of the embodiment:

[0036] In the embodiment, the fixing rod 31 extends from the plate surface of the connecting plate perpendicular to the bottom surface, is arranged horizontally, and penetrates through each layer of simulated skin tissue 32. The used ray indicator 2121 is an infrared ray spotlight arranged in parallel and installed on the head of the pointer 212.

[0037] For example, by adjusting the simulated skin tissue 32, the depth of the simulated blood vessel 1 is 3-4 mm. Then adjust the pointer 212 to 15-20 degrees, which can be specifically determined according to the lecture of the lecturer or the requirements of the courseware. Turn on the infrared ray spotlight, and use the light of the infrared ray spotlight as the needle entry angle to perform the puncture training.

[0038] Application method:

[0039] 1. Set up the training model:

[0040] Initial configuration: stably install the model on the operation platform. According to the training requirements, adjust the fixing rod 31 and the limiting hole to set the simulated skin tissue 32 with different layers to simulate different blood vessel depths.

[0041] 2. Angle guidance training:

[0042] Angle setting: use the telescopic rod 22 to adjust the position of the angle guide plate 21 to set a suitable puncture angle. The students can intuitively adjust and confirm the puncture direction by using the angle scale 2111 and the ray indicator 2121.

[0043] Practical practice: the students perform puncture operation under the assistance of the angle guide plate 21, and through repeated practice, ensure the accuracy of the angle of each puncture, and gradually improve the operation proficiency.

[0044] 3. Depth adjustment training:

[0045] Simulate different depths: By increasing or decreasing the number of layers of simulated skin tissue 32, the model can simulate the location of blood vessels at different depths. Students practice puncture under these settings, learning how to adjust the puncture force and angle to adapt to different depth conditions.

[0046] Operation training: Students perform multiple puncture operations, constantly adjusting and practicing to master puncture skills under different depth conditions.

[0047] 4. Comprehensive training:

[0048] Combined training: After completing individual training, students conduct comprehensive training of angle guidance and depth adjustment. Through continuous puncture operations under various simulation conditions, overall operation skills are improved.

[0049] Feedback and optimization: Training instructors provide real-time feedback based on student performance to help students identify and improve operational problems, further improving training effectiveness. Example two

[0050] Reference Figure 3 With Figure 4 In example two, compared with example one, the two different depth simulation blood vessels 1 in this embodiment can perform two different depth puncture angle training in one blood vessel depth adjustment.

[0051] As a preferred, the fixed rod 31 is perpendicular to the bottom surface, which can fix multiple layers of simulated skin tissue 32 on the bottom plate at the same time, and has more advantages in limiting in the horizontal direction. During the simulation of puncture, different blood vessel depth puncture simulation is performed according to the depth of the two simulation blood vessels 1, without the need to adjust the number of layers of simulated skin tissue 32 during the simulation process.

[0052] As a preferred, the angle guide plate 21 is rotatably connected with the telescopic rod 22 through the rotating rod 221, so as to rotate the angle guide plate 21 to adjust the blood vessel depth, and also improve the flexibility of the angle guide plate 21.
