Abstract

The invention discloses a pre-loaded pen ICI injection device and an operation method. The device comprises a syringe and a push rod, wherein the inner cavity of the syringe is stepped and comprises acoaxial piston cavity and a push rod cavity, a cylindrical drug outlet is formed in the end wall of the piston cavity, and a sealing film is arranged on one side of the drug outlet close to the piston cavity for sealing; a push rod is arranged in the push rod cavity, the two ends of the push rod are respectively fixed with a piston and a push disc, the piston is connected with the inner wall of the piston cavity in a gapless sliding fit manner, the push rod is connected with the inner wall of the push rod cavity in a sliding fit manner, a tension spring surrounding the outer wall of the pushrod is arranged between the push disc and the end surface of the tail part of the syringe, the two ends of the tension spring are respectively fixed on the inner end surface of the push disc and the end surface of the tail part of the syringe, a limiting ring is formed in the periphery of the tension spring; an opening is formed in the limiting ring along the thickness direction; a groove is formed in the tail end of the push disc, and a hole; is formed in the bottom of the groove; and the piston is positioned at the tail of the piston cavity and an ICI liquid medicine is pre-loaded in the piston cavity. The device can solve the technical problems of complicated ICI drug injection operation, complicated structure and high cost of the existing pen syringe.

Description

technical field [0001] The invention belongs to the field of medical aids, in particular to a preinstalled pen-type ICI injection device and an operation method. Background technique [0002] Intracavernous injection of vasoactive drugs (ICI) to induce penile erection can be used to treat male erectile dysfunction. Vasoactive drugs include prostaglandin E1 and so on. Advantages of ICI: easy operation, less interference from the outside world, good repeatability of results, and rapid results. [0003] The operation method of ICI injection: the patient lies on his back, the root of the penis is tied with a rubber band, and the operation is performed under strict aseptic principles after disinfection. The injection site is generally on both sides of the middle and rear part of the penis, and the neurovascular bundle and urethra should be avoided. After fixing the skin at the injection site with your fingers, the needle is vertically inserted into the cavernous body of the pe...
