detailed description

In order to facilitate the understanding of the utility model, the utility model will be described in detail below in conjunction with the preferred embodiments of the utility model given in the accompanying drawings.

As shown in FIG. 1 , an intravenous injection simulation device of the present invention includes a plastic bracket 1 and an injection model 2 , and the injection model 2 is embedded in the plastic bracket 1 . The injection model 2 includes a transparent skin layer 3, a hydrogel subcutaneous tissue layer 4 and an anti-penetration barrier layer 5 from the outside to the inside. The transparent skin layer 3 can be made of PP, PE or PET material structure, which has good transparency and is easy to penetrate. The training process is clearly visible, easy to control the intensity and improve the training effect. The hydrogel subcutaneous tissue layer 4 has good water absorption and is suitable for injecting real liquid to simulate injection training. The simulation effect is good, the injection training can be repeated, and the puncture feels realistic. A number of silicone simulated blood vessels 6 are arranged in the hydrogel subcutaneous tissue layer 4, which can simulate intravenous injection training, and the effect is realistic. The anti-penetration barrier layer 5 selects a hard plastic structure, which can effectively prevent the needle from penetrating and hurting the training personnel. As an embodiment, the transparent skin layer 3 wraps around the hydrogel subcutaneous tissue layer 4 and is stitched or pressed into an integrated structure by an ultrasonic welding process. Furthermore, an adhesive layer can be provided between the hydrogel subcutaneous tissue layer 4 and the anti-penetration barrier layer 5, and fixed by bonding, which is convenient for disassembly, replacement and use. During the intravenous injection training process, the plastic bracket 1 can be placed flat on the desktop. It is also possible to set a card slot 7 that matches the arm at the bottom of the plastic bracket 1, and wear it on the arm for simulated injection training to increase the sense of reality of the training, and a self-adhesive silicone sheet can be set at the bottom of the card slot 7 8. Increase the stability of wearing on the arm through the viscous adsorption of the self-adhesive silicone sheet 8.
