Insulin injection pen with light flashing prompting function

Abstract

The invention relates to an insulin injection pen with a light flashing prompting function. The insulin injection pen with the light flashing prompting function comprises a pen body and a pen cap, wherein an injection amount indicating window is arranged on the pen body, and a button is arranged on the top of the pen body. The insulin injection pen with the light flashing prompting function is characterized in that a light flashing prompting device is further arranged in the pen body and comprises a flashing indicator lamp, a control circuit module, a power supply and a light flashing triggering mechanism, wherein the flashing indicator lamp is electrically connected with the control circuit module, the control circuit module is used for timing and controlling the flashing indicator lamp to work, and the control circuit module is electrically connected with a power supply through the light flashing triggering mechanism. According to the invention, by arrangement of the light flashing prompting device, when insulin is completely injected, the light flashing prompting device starts to work, the flashing indicator lamp prompts a patient to stay a needle under the skin for a period oftime in a flashing manner, the patient stops pressing and pulls the needle only when the flashing indicator lamp stops flashing, and an injection process is completed, so that it ensures that the stoptime of the needle under the skin is not less than 10 seconds, and the injection amount is accurate.

Description

technical field [0001] The invention relates to an insulin injection tool for diabetic patients, in particular to an insulin injection pen with a flashing light prompt function. Background technique [0002] There are many kinds of insulin injection pens in clinical use at present, but in the process of clinical use, we found that the existing insulin injection pens basically have the following two defects that easily lead to inaccurate injection doses: [0003] 1. Insufficient stop time of the needle under the skin: The needle diameter of the insulin pen is designed to be thinner and the flow rate is slower and slower. During the insulin injection process, in order to ensure that all the set insulin injection doses can be injected into the patient's skin, the patient is required to During the operation, the action of inserting the needle into the skin is paused for 10 seconds or even longer. However, during the injection process of many patients, the pause time of the need...

[0002] There are many kinds of insulin injection pens in clinical use at present, but in the process of clinical use, we found that the existing insulin injection pens basically have the following two defects that easily lead to inaccurate injection doses:

[0003] 1. Insufficient stop time of the needle under the skin: The needle diameter of the insulin pen is designed to be thinner and the flow rate is slower and slower. During the insulin injection process, in order to ensure that all the set insulin injection doses can be injected into the patient's skin, the patient is required to During the operation, the action of inserting the needle into the skin is paused for 10 seconds or more

However, during the injection process of many patients, the pause time of the needle under the skin is less than 10 seconds, and some do not even pause.

[0004] 2. Insulin injection dose setting is inaccurate: the existing injection dose indication window is small, and it is difficult for patients with poor eyesight to see the set dose clearly, especially in the initial use of elderly patients, the injection dose setting is often wrong.
