Embodiment Construction

[0040] Such as figure 1 , figure 2 As shown, the pre-filled syringe for continuous treatment includes a casing 2 and a push rod 5 and a piston slidably arranged in the casing 2. The front end of the casing 2 is provided with a cone, and the middle of the cone is provided with a cone communicating with the inside of the casing 2. Hole 8, the outside of the cone is provided with a protective cap 1. The piston includes a front plug 3 and a rear plug 4. The top surface of the front plug 31 and the inner wall of the outer casing 2, the cone hole 8, and the protective cap 1 form a closed space containing the first medicine 6 The top surface 41 of the rear plug, the inner wall of the outer casing 2 and the bottom surface 32 of the front plug form a closed space containing the rear drug 7. The front end of the inner wall of the outer casing 2 is provided with a groove 21 on the inner wall of the outer casing parallel to the axis of the outer casing 2. The depth is less than the thickne...

Abstract

The invention provides a pre-filled syringe for continuous treatment. The pre-filled syringe comprises a shell, a push rod and a piston; the push rod and the piston are arranged in the sleeve in a sliding mode, a cone head is arranged at the front end of the shell, a cone hole which is communicated with the interior of the shell is formed in the middle of the cone head, a protective cap is arranged outside the cone head, the piston comprises a front plug and a rear plug, a closed space containing a first drug is formed by the top face of the front plug, the inner wall of the shell, the cone hole and the protective cap, a closed space containing a post drug is formed by the top face of the rear plug, the inner wall of shell and the bottom face of the front plug, a shell inner wall groove parallel to the shell axis is formed in the front end of the inner wall of the shell, a shell front end groove is formed in the inner wall of the front end of the shell, one end of the shell front end groove is communicated with the front end of the shell inner wall groove, the other end of the shell front end groove is communicated with the cone hole, and the top face of the front plug is matched with the inner wall of the front end of the shell. According to the pre-filled syringe for continuous treatment, the problem of incompatibility of different drugs in the treatment process is solved.

Description

Technical field [0001] The invention belongs to the field of medical equipment, and particularly relates to a pre-filled syringe capable of continuous treatment. Background technique [0002] The pre-filled syringe is a new type of medicine packaging container with high technical content and suitable for injection and injection dosage forms. The pre-filled syringe is to directly fill the injection drug in the syringe, combine the syringe and the drug solution packaging container into one, and directly inject when used, which is very convenient. With the development of medical science and the promotion of various diagnosis and treatment technologies, especially the clinical application of new drugs and high-tech in recent years, the application of pre-filled syringes has become more and more extensive. [0003] With the development of the pharmaceutical industry, more and more new drugs have appeared, and some obvious drawbacks have also appeared, that is, drugs that are contraindi...
