According to the above description and with various injection methods, each drawing is only shown in the area to be described. For the actual completeness, please see the first figure. The first injection area 30 mainly provides PORT-A injection methods. The so-called PORT-A, also known as artificial blood vessel, is a type that can be used for patients who need long-term and repeated infusion of drugs, blood, high-nutrient fluids or other fluids. It can avoid infection or discomfort caused by repeated venous puncture and reduce the time when receiving chemotherapy. The probability of drug extravasation. This kind of artificial blood vessel is mainly a siliceous component that must be implanted in the body. Generally, it can be indwelled for a long time under the condition of no infection and obstruction of the pipeline. It is usually placed on the flat surface of the chest under the clavicle. On the outside, a bump about the size of a ten yuan coin does not affect personal daily life, leisure and sports. Its advantages are that it is convenient to inject, placed under the skin, can be used repeatedly and for a long time, and does not require special care in ordinary times.

Continuing the above, so when practicing, medical staff mainly need to practice the feel of inserting the relevant needle assembly suitable for PORT-A injection into at least one base 3.

Moreover, when the at least one base 3 is installed on the human body, most of it is carried out in an surgical manner, and it is difficult to provide a general simple injection operation by the nursing staff. Therefore, the assembly of the at least one base 3 and the metal sheet 31 is only a simple plug-in connection in this creation. No need to use any medical knowledge.

Please see the fifth and sixth pictures again. The second injection zone 40 of this creation provides intravenous injection exercises. Intravenous injection means direct injection of liquid substances such as blood, medicinal solution, nutrient solution into the vein, and the injection method is to use a needle 20 Incline upwards, and at an angle of 15°~30° with the skin, pierce into the subcutaneous from above or from the side of the vein, and then sneak into the vein along the direction of the vein. Therefore, a plurality of second pipelines 6 are provided inside the second injection area 40. The setting of each second pipe 6 is to simulate the distribution of human veins. Therefore, when the user uses the injection needle 20 for simulation exercises, he only needs to align the needle 20 with any of the second pipes 6 and insert it in a related manner. Then use the syringe 70 to inject food coloring. As mentioned above, if the injection needle 20 is accurately inserted into any of the second pipes 6, the food coloring can be injected from the injection needle 20 into the second pipe 6 and overflow the second pipe 6. The perfusion hole 7 can confirm that the user's technique accurately allows the injection needle 20 to be inserted into the second pipe 6, and the user can practice repeatedly to increase the accuracy of the injection needle 20 insertion.

Next, the third injection area 50 will be described. The third injection area 50 provides users with practice subcutaneous injection methods.
