Skin retention device for a medical jet injection unit

摘要: A skin retention device 10 for a medical jet-injection unit 20 comprises contact face provided with adhesive 12 in the area surrounding and close to injection opening(s) 1 of nozzle 21 which ensures god between 30 subject chosen an injection. Consequently force can be lowered dramatically. In case two-stage jet-injections, initial because point significantly reduces energy consuming elastic expansion area, second high degree fixed positioning opening relative channel made during stage. Thus safety is achieved, minimizing risk whet shots, while lift lower decreases damage underlying tissue.
