Description

Technical Field

[0001] The utility model relates to the technical field of medical supplies, in particular to a scalp vein puncture model for nursing training. Background Art

[0002] The scalp vein puncture model for nursing training is a teaching model specifically designed for medical teaching, training, or skill practice. It primarily simulates the scalp vein puncture process in infants. This model is designed to help healthcare professionals, medical students, and related practitioners practice scalp vein puncture techniques in a safe environment, thereby improving their practical skills and proficiency. During an intravenous injection in a scalp vein puncture model for nursing training, a certain amount of simulated blood is typically contained within the model. If the puncture is successful, the simulated blood flows through the tubing system into the puncture needle. When the puncture needle correctly penetrates the simulated blood vessel, the simulated blood flows back through the needle into the puncture device, creating a noticeable blood return effect.

[0003] When performing multiple scalp injection experiments, using the same batch of simulated blood for a long time may cause contamination, coagulation or other problems, affecting the simulation effect. In multiple injection experiments, the needle will repeatedly pierce the skin part simulating the scalp vein, which will cause wear, deformation or even damage to the skin surface, thereby affecting the appearance and authenticity of the model. After a period of use, the model will become unreliable and even unusable for training purposes. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4 , the utility model provides a technical solution:

[0023] See Figure 2 and Figure 3 As shown, a scalp vein puncture model for nursing training includes a skull shell 1, which includes a scalp vein network 2 and a base 3. One end of the scalp vein network 2 is located inside the skull shell 1, and the end inside is connected to a connecting tube 5. A water pump box 6 is provided below the connecting tube 5, and a water pump 7 is provided in the water pump box 6. A pipe is installed between the connecting tube 5 and the water pump 7 to connect the two. A blood simulation liquid box 8 is installed on the side of the water pump 7 away from the connecting tube 5;

[0024] The blood simulation liquid box 8 is connected to the base 3. The upper and lower sides of the blood simulation liquid box 8 are respectively provided with a discharge valve 9 and a discharge valve 10. The discharge valve 9 and the discharge valve 10 are located on the outside of the base 3. A part of the scalp venous network 2 located on the outside of the skull shell 1 is covered with a silicone film 16, and a Velcro 17 is provided on the outside of the silicone film 16.

[0025] During the specific implementation process, the scalp venous network 2 is the core part of the model, simulating the venous network under the real scalp. One end of the scalp venous network 2 extends to the inside of the skull shell 1 and is connected to the water pump system through the connecting tube 5 to realize the circulation of the blood simulation liquid. The blood simulation liquid box 8 can store the liquid used to simulate blood. The liquid usually has a color, viscosity and flow characteristics similar to real blood. The feeding valve 9 is used to inject blood simulation liquid into the scalp venous network 2, and the discharge valve 10 is used to discharge or replace the old simulation liquid. The silicone membrane 16 covers the outer part of the scalp venous network 2 to simulate the real skin touch. The Velcro 17 is used to fix the silicone membrane 16 to ensure that it will not loosen or fall off during training, and it is convenient to replace the silicone membrane 16 at any time after frequent use.

[0026] See Figure 1 As shown, a scalp vein puncture model for nursing training is shown. The bottom of the base 3 is fixedly connected to a connecting rod 22, and the bottom end of the connecting rod 22 is installed with a universal ball 11. The universal ball 11 is rotatably connected to a connecting block 12. An electric telescopic rod 13 is provided under the connecting block 12, and the top of the electric telescopic rod 13 is detachably connected to the connecting block 12 by bolts.

[0027] During the specific implementation process, the universal ball 11 is installed at the bottom end of the connecting rod 22 and has the characteristic of multi-directional rotation. This design allows the model to rotate and tilt in all directions on the horizontal plane to adapt to the puncture practice needs of different angles and directions. The connecting block 12 is rotatably connected to the universal ball 11 and serves as the support point of the electric telescopic rod 13. The design of the connecting block 12 enables the electric telescopic rod 13 to be firmly installed on the universal ball 11 and rotate with it. The electric telescopic rod 13 is detachably connected to the connecting block 12 by bolts. This design facilitates maintenance and replacement. The main function of the electric telescopic rod 13 is to adjust the height of the model to adapt to medical staff of different heights and usage environments. By controlling the extension and retraction of the electric telescopic rod 13, the model can be easily adjusted to the appropriate height, thereby improving the comfort and effect of training.

[0028] See Figure 4 As shown, a scalp vein puncture model for nursing training is provided. The electric telescopic rod 13 is provided with a box body 4 outside. A top cover 18 is installed on the top of the box body 4. There are two top covers 18, which are symmetrically arranged and have handles 20 on their upper surfaces. The two top covers 18 are connected to the box body 4 with hinges 19.

[0029] During the specific implementation process, the box body 4 serves as the external protective shell of the electric telescopic rod 13, and plays multiple protective roles such as dustproof, waterproof, and anti-collision. When the electric telescopic rod 13 is retracted to the initial state, the skull shell 1 can be stored in the box body 4, and the two top covers 18 are connected to the box body 4 through the hinge 19. The hinge 19 not only allows the top cover 18 to rotate freely within a certain range, but also ensures the tight connection and stability between the top cover 18 and the box body 4.

[0030] See Figure 1 As shown, a scalp vein puncture model for nursing training is shown. A controller 21 is installed on the side of the blood simulation liquid box 8 away from the base 3. The output end of the controller 21 is connected to the input end of the water pump 7 and the electric telescopic rod 13.

[0031] During the specific implementation process, the main function of the controller 21 is to receive the user's operating instructions and transmit the instructions to components such as the water pump 7 and the electric telescopic rod 13 through the internal circuit, thereby achieving precise control of these components. Through the controller 21, the user can control the start and stop of the water pump 7, thereby adjusting the circulation of the blood simulation fluid in the scalp venous network 2. This control method allows the user to simulate blood flow conditions with different flow rates to adapt to different training needs. Through the controller 21, the user can conveniently adjust the telescopic length of the electric telescopic rod 13, thereby changing the overall height of the model.

[0032] See Figure 3 As shown, a scalp vein puncture model for nursing training is shown. The skull shell 1 is made of rubber material, the scalp vein network 2 is made of silicone material, and a groove corresponding to a part connected to the scalp vein network 2 is opened on the skull shell 1.

[0033] During the specific implementation process, a groove corresponding to a part connected to the scalp venous network 2 is opened on the skull shell 1. This design enables the scalp venous network 2 to fit tightly on the skull shell 1 to form a whole. The shape and size of the groove match the scalp venous network 2, ensuring a seamless connection between the two. The groove design not only improves the tightness of the connection between the skull shell 1 and the scalp venous network 2, but also makes the model more realistic in appearance. Users can feel a more realistic skull shape and blood vessel distribution during operation, thereby improving the immersion and effect of training.

[0034] It should be noted that the skull shell 1 is made of rubber material, which has good flexibility and elasticity and can simulate the touch and shape of a real skull. The rubber material also has a certain durability and can withstand a certain degree of extrusion and distortion without being easily damaged.

[0035] See Figure 1As shown, a scalp vein puncture model for nursing training is shown, in which a support plate 14 is connected to the bottom of the box 4, and a universal wheel 15 is installed at the bottom of the support plate 14.

[0036] In the specific implementation process, the universal wheels 15 are installed at the bottom of the support plate 14, so that the model can be easily moved on different surfaces. They not only provide flexible steering capabilities, but also allow users to move the entire model through simple push and pull operations, greatly improving the convenience of use.

[0037] Working principle:

[0038] Step 1: The blood simulation liquid box 8 stores a liquid used to simulate blood. This liquid has a color, viscosity, and flow characteristics similar to real blood. The feed valve 9 and the discharge valve 10 are used to inject and discharge the blood simulation liquid into the scalp venous network 2, respectively. By controlling these two valves, precise management of the flow of the simulation liquid can be achieved. The water pump 7 is connected to the scalp venous network 2 through the connecting tube 5, driving the blood simulation liquid to circulate in the scalp venous network 2. The start and stop of the water pump 7 is controlled by the controller 21 to simulate blood flow conditions at different flow rates.

[0039] Step 2: The electric telescopic rod 13 is detachably connected to the connecting block 12 by bolts and is installed under the universal ball 11. The extension and retraction of the electric telescopic rod 13 is controlled by the controller 21, which is used to adjust the overall height of the model to adapt to medical staff of different heights and usage environments. The universal ball 11 and the connecting rod 22 allow the model to rotate and tilt in all directions on the horizontal plane, and are connected to the electric telescopic rod 13 through the connecting block 12 to achieve synchronous adjustment of height and angle.

[0040] Step 3: The top cover 18 is connected to the box body 4 through the hinge 19, allowing the user to easily open and close the box body 4. The handle 20 on the top cover 18 facilitates the transportation and movement of the entire model. The universal wheels 15 are installed at the bottom of the box body 4 to provide stable support and flexible mobility.
