Pop-up insulin pen

Abstract

The invention discloses a pop-up insulin pen. The pop-up insulin pen comprises an outer pen container, an insulin pen cartridge and an inner pen container, wherein the insulin pen cartridge is arranged inside the outer pen container, the inner pen container is arranged between the insulin pen cartridge and the outer pen container and is in threaded connection with the inner pen container, a protecting sleeve is arranged at the bottom of the outer pen container, a spring is arranged between the protecting sleeve and the insulin pen cartridge, the two ends of the spring are fixedly connected with the bottom of the insulin pen cartridge and the protecting sleeve respectively, an insulin syringe needle is connected to the bottom of the insulin pen cartridge and is arranged inside the spring, baffles are arranged at the top of the protecting sleeve, and limiting plates are arranged on the outer wall of the insulin pen cartridge. By means of the pop-up insulin pen, a patient conveniently adjusts the pressure inside the insulin pen cartridge according to actual demands to achieve the purpose of controlling the injection speed of insulin, the probability that the hands of the patient are punctured can also be greatly lowered, and the pop-up insulin pen is simple in structure and high in practicability.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a pop-up insulin pen. Background technique [0002] For more severe diabetic patients, insulin injections are required every day, and an insulin pen is a commonly used tool for injecting insulin. When injecting, the patient puts the insulin refill filled with insulin into the insulin pen, and after the patient penetrates the insulin needle into the skin, presses the insulin pen, and the insulin will be injected into the body. Insulin pen is a common insulin injection device. However, because the cap has a very small inner diameter in order to adapt to the needle, hand accidents often occur when the user puts the cap back on the needle. [0003] Therefore, it is necessary to invent a pop-up insulin pen to solve the above problems. Contents of the invention [0004] The object of the present invention is to provide a pop-up insulin pen to solve the problems raised in the above-me...
