The invention relates to a device for the administration of injectable products with a controlled flow rate, including: a container (23) filled with an injectable product and taking the form of a syringe and ampule, an injection port (25), and a valve (21, 41, 61, 81, 91) controlling the outlet pressure and flow rate, disposed between the injectable product and the injection port (25), as well as means for varying the outflow rate according to the pressure applied during the administration of the injectable product, with the administration of the product being stopped with the closure of the valve (21, 41, 61, 81, 91 ) when the pressure exceeds a pre-defined threshold, and means for preventing the backflow of fluids as the injectable product is being administered. The valve (21, 41, 61, 81, 91 ) can be positioned either in the container (23) or at an injection end (27) including the injection port (25) which is coupled to the container (23). |
