Technical Field
[0001] The utility model relates to the field of medical instruments, in particular to a venipuncture training device. Background Art
[0002] Medical nursing mainly studies basic knowledge and skills in human physiology and pathology, basic medicine, clinical nursing, preventive health care, etc. In hospitals, doctors need to teach nursing to some intern nurses, such as acupuncture training for patients, and intern nurses usually need to use arm models for acupuncture training.
[0003] When trainees are doing acupuncture training on an arm model, there is only one blood vessel structure on the existing training arm to simulate an actual patient's blood vessel. However, after a single blood vessel is punctured during training, the plasma inside will flow out and the blood vessel needs to be replaced, which is very inconvenient. In addition, the thickness of blood vessels varies from person to person, and the actual condition of a patient's arm cannot be simulated, making it difficult to improve the training effect. Utility Model Content
[0004] The utility model designs a venipuncture training device to solve the technical problems raised in the background technology and proposes the following technical solutions:
[0005] A venous puncture training device comprises a support plate, a simulation arm and multiple groups of simulated blood vessels of varying thicknesses, wherein the upper ends of both sides of the support plate are fixedly connected to support frames, the upper end of the support plate is also fixedly connected to a mounting seat, and the simulation arm is rotatably connected to the mounting seat via a bearing, the outer wall of the simulation arm is evenly provided with multiple groups of blood vessel grooves that are snap-fitted with the simulated blood vessels, the simulated blood vessels are spliced from multiple strip-shaped branch pipes, one end of the simulation arm movably passes through the mounting seat and is fixedly connected to a rotating disk, the upper end of the support plate is fixedly connected to a fixed plate at the outer end of the rotating disk, and a limit pin snap-fitted to the rotating disk is movably inserted through the outer side of the fixed plate.
[0006] Preferably, a rubber pad is provided at the bottom of the support plate.
[0007] Preferably, a threaded rod is threadedly connected to the upper end of the support frame, and a suction cup is rotatably connected to the bottom of the threaded rod.
[0008] Preferably, a friction pad is provided on the inner wall of the blood vessel groove, and the friction pad is frictionally engaged with the outer wall of the simulated blood vessel.
[0009] Preferably, a plurality of groups of limiting holes are evenly arranged on the outer side surface of the rotating disk, the plurality of groups of limiting holes are arranged in a ring shape, and the plurality of groups of limiting holes correspond to the plurality of groups of simulated blood vessels in a one-to-one manner.
[0010] Preferably, one end of the limit pin is plug-fitted into the limit hole, the other end of the limit pin is fixedly connected to the limit block, and the limit block is connected to the outer side of the fixed plate through a spring.
[0011] Preferably, the spring is in a contracted state by default.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] The utility model rotatably installs the simulation arm through the support plate and the support frame, and installs multiple groups of simulated blood vessels of different thicknesses on the outer side of the simulation arm. When performing acupuncture training, the simulation arm can be rotated to select simulated blood vessels of different thicknesses, so that patients with blood vessels of different thicknesses can be simulated for acupuncture training and the training effect of medical staff can be improved. At the same time, the simulated blood vessel is spliced with multiple groups of strip blood vessels. One simulated blood vessel can be used for acupuncture training multiple times without the need to frequently replace the simulated blood vessel, thereby increasing the overall portability of use, having a significant improvement in practical effect, and worthy of promotion and use in the existing market.

DETAILED DESCRIPTION
[0018] In order to make the purpose, technical scheme and advantages of the implementation examples of the utility model clearer, the technical scheme in the implementation examples of the utility model will be clearly and completely described below in combination with the implementation examples of the utility model. Obviously, the implementation examples described are part of the implementation cases of the utility model, not all of the implementation cases. Based on the implementation examples in the utility model, all other implementation examples obtained by general technical and technical personnel in this field without creative work are within the scope of protection of the utility model.
[0019] Reference Manual Attached Figure 1-3A venous puncture training device includes a support plate 1, a simulation arm 4 and multiple groups of simulated blood vessels 7 of different thicknesses. The upper ends of both sides of the support plate 1 are fixedly connected with a support frame 2, and the upper end of the support plate 1 is also fixedly connected with a mounting seat 3. The simulated arm 4 is rotatably connected to the mounting seat 3 through a bearing 5. The outer wall of the simulated arm 4 is evenly provided with multiple groups of blood vessel grooves 6 that are engaged with the simulated blood vessels 7. The simulated blood vessels 7 are spliced by multiple strip-shaped branches 8. Based on the above structure, the device can directly engage the simulated blood vessels 7 of different thicknesses in the corresponding blood vessel grooves 6 on the outer side of the simulated arm 4. During the needle-piercing training, the medical staff can rotate the simulated arm 4 in turn and select simulated blood vessels of different thicknesses for needle-piercing operations, which can effectively improve the overall training effect. During the needle-piercing, the pillow enters a strip-shaped branch 8 in the simulated blood vessel 7. When the strip-shaped branch 8 is used, the subsequent training can continue to perform needle-piercing training on other strip-shaped branches 8 in the group of simulated blood vessels 7. There is no need to frequently replace the simulated blood vessels 7 for training, and it is very portable to use.
[0020] It should be noted that the strip tube 8 can be filled with plasma or similar simulated training liquid, and the outer wall of the strip tube 8 is wrapped with silicone material to simulate the scene of the combination of human skin and blood vessels, making it easier for medical staff to engage in actual usage scenarios for training.
[0021] Among them, a rubber pad 101 is arranged at the bottom of the support plate 1, which can increase the overall anti-slip effect of placement, and a threaded rod 201 is threadedly connected to the upper end of the support frame 2, and a suction cup 202 is rotatably connected to the bottom of the threaded rod 201. When in use, the threaded rod 201 can be rotated to press the suction cup 202 down to adsorb to the work surface, thereby ensuring the overall stability during acupuncture training.
[0022] Among them, a friction pad is fitted on the inner wall of the blood vessel groove 6, and the friction pad is frictionally engaged with the outer wall of the simulated blood vessel 7, which is convenient for replacing the simulated blood vessel 7 or adjusting the installation position, and is very convenient to use.
[0023] Among them, one end of the simulation arm 4 movably passes through the mounting seat 3 and is fixedly connected to the rotating disk 9, and the upper end of the support plate 1 is located at the outer end of the rotating disk 9 and is fixedly connected to the fixed plate 10, and the outer side of the fixed plate 10 is movably penetrated and plugged with a limit pin 11 that is clamped to the rotating disk 9, and a plurality of groups of limit holes 901 are evenly arranged on the outer side of the rotating disk 9, and the plurality of groups of limit holes 901 are arranged in a ring shape, and the plurality of groups of limit holes 901 correspond one-to-one with the plurality of groups of simulated blood vessels 7, one end of the limit pin 11 is plugged into the limit hole 901, and the other end of the limit pin 11 is fixedly connected to the limit block 1101, and the limit block 1101 is connected to the outer side of the fixed plate 10 through a spring, and the spring is in a contracted state in the default state. During the acupuncture training process, when adjusting blood vessels of different thicknesses, the staff will pull the limit block 1101 in advance and stretch the spring to disengage the limit pin 11 from the outside of the limit hole 901. Then, the simulated arm 4 can be rotated to adjust the position of the simulated blood vessels 7 of different thicknesses. After the adjustment is completed, the limit pin 1101 is released and the limit pin 11 is driven by the elastic contraction of the spring to engage in the limit hole 901 corresponding to the outside of the rotating disk 9 at the outer end of the simulated arm 4, thereby completing the angle fixation of the simulated arm 4, which is convenient for the relative stability of the arm during acupuncture training.
