Problems solved by technology

If the patient does not live in the hospital or does not have medical staff around him, he has to operate the syringe to inject some parts of the body by himself. However, the existing syringe needs to continuously exert force during the injection, pushing the syringe until the drug is injected, which is not convenient for the patient to operate alone.

Abstract

The invention provides an injection pen sleeve convenient for injection. The injection pen sleeve convenient for injection comprises a first shell, a second shell, a push rod, a movable assembly, anda hidden needle sleeve; a syringe is movably arranged in a first chamber and a second chamber when the syringe is between quiescent state and working state; when the syringe is at the quiescent state,the syringe is located inside the first chamber and the second chamber; when the syringe is at the working state, the needle of the syringe extends out of the second chamber; the push rod is movablyarranged in the first shell when the push rod is between a locked position and an open position; when the push rod is at the locked position, no force is applied on the syringe, so that, the syringe is in stationary state; when the push rod moves from the locked position to the open position, the syringe is pushed to change from the stationary state to working state; and the movable assembly cooperates with the push rod so as to adjust configuration of the push rod. The injection pen sleeve convenient for injection disclosed by the embodiments of the invention is simple in structure, convenient to use, and feasible for injection depth adjustment.

Description

technical field [0001] The invention relates to the technical field of syringes, in particular to an injection pen cover for easy injection. Background technique [0002] When treating a certain disease, it is necessary to inject drugs to the patient on time. If the patient does not live in the hospital or does not have medical staff around him, he has to operate the syringe to inject some parts of the body by himself. However, the existing syringe needs to continuously exert force during the injection, pushing the syringe until the drug is injected, which is not convenient for the patient to operate alone. . In addition, some parts also have requirements for injection depth. Contents of the invention [0003] In view of this, the present invention provides an injection pen case for easy injection, which has a simple structure and is convenient to use. [0004] The injection pen case for easy injection according to the embodiment of the present invention includes: a fir...
