[0002] Infusion training simulators are widely used in medical colleges, nursing training institutions, hospitals, and other settings. As a teaching tool for training skills such as intravenous puncture, infusion, and blood drawing, they are an indispensable teaching tool in medical education and training. Through repeated practice, trainees can master skills such as intravenous puncture, infusion, and blood drawing, laying a solid foundation for future clinical work.

[0003] When using a traditional infusion training simulated arm, the surface and internal simulated blood vessels of the simulated arm will be damaged as the number of punctures increases, affecting the puncture feel and increasing the deviation from the actual clinical puncture effect, thus affecting the effectiveness of puncture training. Furthermore, frequent replacement of the arm model is not conducive to controlling the cost of infusion training. Utility Model Content

[0004] This disclosure relates to an infusion training arm made of silicone material, which addresses the problem that when using traditional infusion training simulation arms, as the number of punctures increases, the surface of the simulation arm and the internal simulation blood vessels will be damaged, affecting the puncture feel, increasing the deviation from the actual clinical puncture effect, affecting the effect of puncture training, and the frequent replacement of the arm model is not conducive to the control of infusion training costs.

[0005] In a first aspect, this disclosure provides an infusion training arm made of silicone material, specifically comprising: an arm model, wherein an adhesive groove is formed on the surface of the arm model, a puncture silicone pad is adhesively fixed inside the adhesive groove, a simulated blood vessel is provided inside the puncture silicone pad, an infusion tube is fixedly connected inside the arm model, the inner end of the infusion tube is connected to the simulated blood vessel, a reservoir is fixedly connected to the left end of the arm model, and the left end of the infusion tube is fixedly connected to the right end of the reservoir, the infusion tube being in communication with the reservoir.

[0006] Furthermore, a mating slot is provided on the left edge of the adhesive groove surface.

[0007] Furthermore, a connecting sleeve is fixedly connected to the right end of the infusion connecting tube. The connecting sleeve is a circular sleeve and is located inside the docking port.

[0008] Furthermore, the lower end of the simulated blood vessel is fixedly connected to a blood vessel docking cannula, and a cannula through hole is provided on the left side of the cannula wall.

[0009] Furthermore, a movable plug is movably connected inside the connecting tube sleeve, and a plug return spring is fixedly connected to the lower end of the movable plug, while the upper end of the plug return spring is fixedly connected to the lower end of the connecting tube sleeve.

[0010] Furthermore, an injection port is provided on the right edge of the liquid storage cylinder wall, and a pressure piston is tightly slidably connected inside the liquid storage cylinder. A piston rod is fixedly connected to the left end of the pressure piston, and the piston rod moves through the left wall of the liquid storage cylinder.

[0011] Furthermore, a pressure spring is fixedly connected to the left end face of the pressure piston, and the left end of the pressure spring is fixedly connected to the left wall of the liquid storage cylinder.

[0012] This invention provides an infusion training arm made of silicone material, which has the following beneficial effects:

[0013] The infusion training arm model of this invention has a puncture silicone pad attached to the puncture area. When the puncture silicone pad is damaged, it can be removed from the adhesive groove and a new puncture silicone pad can be installed. The replacement cost is low and it helps to control the cost of infusion training.

[0014] In addition, a simulated blood vessel is installed inside the puncture silicone pad. When the puncture silicone pad is installed normally, the simulated blood vessel is connected to the reservoir through the internal pipe of the arm model.

At the same time, the outlet end of the infusion tube is automatically sealed to prevent simulated blood pressure from flowing out. After installing the new puncture silicone pad, the simulated blood vessel is connected to the infusion tube, so that the infusion tube and the simulated blood vessel are automatically connected. The replacement method is quick and easy. Attached Figure Description

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] Example 1: Please refer to Figures 1 to 9 :

[0032] This utility model proposes an infusion training arm made of silicone material, comprising: an arm model 1, an adhesive groove 101 on the surface of the arm model 1, a puncture silicone pad 2 glued and fixed inside the adhesive groove 101, a simulated blood vessel 201 inside the puncture silicone pad 2, an infusion tube 3 fixedly connected inside the arm model 1, the inner end of the infusion tube 3 connecting to the simulated blood vessel 201, a reservoir 5 fixedly connected to the left end of the arm model 1, and the left end of the infusion tube 3 fixedly connected to the right end of the reservoir 5, with the infusion tube 3 communicating with the reservoir 5; and a puncture silicone pad 2. The pad 2 is pasted inside the pasting groove 101. The puncture silicone pad 2 serves as the puncture area for puncture training. As the number of punctures increases, when the puncture silicone pad 2 is damaged, it can be removed and discarded, and a new puncture silicone pad 2 can be installed inside the pasting groove 101. There is no need to discard the entire arm model 1, which helps control the cost of infusion training. Simulated blood is stored in the reservoir 5 and transported to the simulated blood vessel 201 through the infusion tube 3. The simulated blood vessel 201 imitates human blood vessels, improving the realism of puncture training.

[0033] In this embodiment, an injection port 501 is provided on the right edge of the wall of the storage cylinder 5. A spiral sealing plug is installed on the injection port 501, allowing simulated blood to be injected into the storage cylinder 5. A pressure piston 502 is tightly slidably connected inside the storage cylinder 5. A piston rod 503 is fixedly connected to the left end of the pressure piston 502, and the piston rod 503 moves through the left wall of the storage cylinder 5. A pressure top spring 504 is fixedly connected to the left end face of the pressure piston 502, and the left end of the pressure top spring 504 is fixedly connected to the left wall of the storage cylinder 5. Under normal conditions, the simulated blood is stored in the space to the right of the pressure piston 502 inside the storage cylinder 5. The pressure top spring 504 applies a thrust to the pressure piston 502, giving the simulated blood a certain pressure, mimicking human blood pressure. When the puncture needle enters the simulated blood vessel 201, the blood inside the simulated blood vessel 201 can enter the puncture needle, mimicking the phenomenon of "blood return". This makes the training process closer to the real scene and helps trainees better adapt to actual operation psychologically.

[0034] In Example 2, based on Example 1, a docking port 102 is provided on the left edge of the adhesive groove 101. A connecting sleeve 301 is fixedly connected to the right end of the infusion connecting tube 3. The connecting sleeve 301 is a circular sleeve located inside the docking port 102. A blood vessel docking tube 202 is fixedly connected to the lower end of the simulated blood vessel 201. A tube through hole 203 is provided through the left side of the tube wall of the blood vessel docking tube 202. A movable plug 4 is movably connected inside the connecting sleeve 301. A plug return spring 401 is fixedly connected to the lower end of the movable plug 4. The upper end of the plug return spring 401 is fixedly connected to the lower end of the connecting sleeve 301. When the puncture silicone pad 2 is installed inside the adhesive groove 101, the vascular docking cannula 202 is inserted into the connecting sleeve 301, and the cannula through hole 203 is aligned with the infusion connecting tube 3, allowing the simulated blood inside the infusion connecting tube 3 to enter the simulated blood vessel 201. When the puncture silicone pad 2 is removed, the vascular docking cannula 202 is pulled out from inside the connecting sleeve 301. Under the pulling force of the plug reset spring 401, the movable plug 4 moves upward and blocks the channel connecting the infusion connecting tube 3 and the connecting sleeve 301, preventing the simulated blood inside the infusion connecting tube 3 from flowing out and avoiding leakage of simulated blood during the replacement of the puncture silicone pad 2, which would cause pollution to the training environment.

[0035] The working principle of this embodiment is as follows: First, while the piston rod 503 is pulled to the left, simulated blood is injected into the reservoir 5 through the injection port 501. After the injection is completed, the injection port 501 is sealed with a screw plug. The puncture silicone pad 2 is then attached to the adhesive groove 101 with double-sided tape, and the vascular docking cannula 202 is inserted into the connecting tube sleeve 301. During puncture practice, the puncture needle is held and used to puncture the puncture silicone pad 2. When the puncture needle pierces the simulated blood vessel 201, the simulated blood inside the simulated blood vessel 201 enters the puncture needle under the pressure of the pressure spring 504, simulating the phenomenon of "blood return". This makes the training process closer to the real scene, helps trainees to better adapt to the actual operation psychologically, and allows them to judge whether the puncture has successfully entered the blood vessel. After repeated punctures, the puncture silicone pad 2 becomes damaged. It is then removed from the adhesive groove 101, and simultaneously, the vascular docking cannula 202 is removed from the connecting sleeve 301. Under the tension of the plugging column reset spring 401, the movable plugging column 4 moves upward and blocks the channel connecting the infusion tube 3 and the connecting sleeve 301, preventing simulated blood from flowing out of the infusion tube 3. This avoids leakage of simulated blood during the replacement of the puncture silicone pad 2, which could contaminate the training environment. A new puncture silicone pad 2 is then installed. As the vascular docking cannula 202 is inserted into the connecting sleeve 301, the movable plugging column 4 is pushed downward, aligning the cannula through-hole 203 with the outlet of the infusion tube 3. This reconnects the reservoir 5 with the simulated blood vessel 201, allowing simulated blood to be injected into the simulated blood vessel 201, thus completing the refurbishment of the infusion training arm model.
