本发明涉及胰岛素注射器件，针对开环胰岛素注射，为一种智能胰岛素泵系统。The invention relates to an insulin injection device, which is an intelligent insulin pump system for open-loop insulin injection.
背景技术Background technique
胰岛素泵是用来模拟人体胰腺分泌胰岛素的一种胰岛素输注系统，它的作用是模拟人体提供持续的基础胰岛素分泌量，还可在进餐前提供大剂量的胰岛素，控制餐后高血糖，基本上达到了模拟胰腺分泌胰岛素的功能，使其接近生理昼夜胰岛素水平，从而使糖尿病患者24小时血糖控制在一个理想水平。Insulin pump is an insulin infusion system used to simulate the secretion of insulin by the human pancreas. Its function is to simulate the human body to provide continuous basal insulin secretion, and it can also provide large doses of insulin before meals to control postprandial hyperglycemia. It achieves the function of simulating the secretion of insulin from the pancreas, making it close to the physiological circadian insulin level, so that the 24-hour blood sugar of diabetic patients can be controlled at an ideal level.
目前的开环胰岛素泵仅仅包括一个泵体，泵体主要由以下部分组成：泵主机、储药器和与之相连的输注管路，而输注管路前端有一引导针扎入皮下。泵主机主要由电池、MCU、控制电路、LCD显示、按键和驱动马达及其调速机构、传动系统等组成。其原理是：由MCU和控制电路驱动马达推动储药器上的活塞，按照设定的剂量，通过输注管路将胰岛素注入病人体内。医生必须利用泵体上安装的几个按键开关，按患者实际的需求设置不同的时段和剂量以及其它相关参数，并将其存入存储器中，胰岛素注射量由MCU控制，可设置基础量和餐前大剂量，以使全天血糖控制在理想水平。但为了便于携带，胰岛素注射泵的体积通常都不大，受体积限制，设置胰岛素泵的按键也不大，且都是通过4～6个按键来进行设置，这种设置方法对医生来说是一件极其复杂的任务，而患者本身根本没有能力进行相关参数的设置，胰岛素泵的设置过程具有很强的专业性，泵体本身体积很小，狭小的空间上少数几个按键配合LCD分层菜单操作起来异常复杂，并且极易出错，一旦患者的饮食和生活习惯改变，就要重新调整胰岛素基础剂量和餐前剂量等设置，又要重复上述复杂的设置过程，这也极大地限制了胰岛素泵的使用和推广，也是其价格高昂，通常只能在医院中，由医生操作使用的一个重要原因。The current open-loop insulin pump only includes a pump body, and the pump body is mainly composed of the following parts: a pump host, a drug storage device and an infusion line connected thereto, and a guide needle is inserted into the subcutaneous area at the front end of the infusion line. The main engine of the pump is mainly composed of battery, MCU, control circuit, LCD display, buttons, drive motor and its speed regulating mechanism, transmission system and so on. The principle is: the motor is driven by the MCU and the control circuit to push the piston on the drug storage device, and inject insulin into the patient's body through the infusion line according to the set dose. The doctor must use several key switches installed on the pump body to set different time periods, doses and other related parameters according to the actual needs of the patient, and store them in the memory. The insulin injection volume is controlled by the MCU, and the basic volume and meal can be set. Take a large dose beforehand to keep your blood sugar under control throughout the day at an ideal level. However, for portability, the volume of insulin injection pumps is usually not large. Due to volume limitations, the buttons for setting insulin pumps are not large, and they are all set by 4 to 6 buttons. This setting method is very convenient for doctors. It is an extremely complicated task, and the patient is not capable of setting related parameters at all. The setting process of insulin pump is very professional. The menu operation is extremely complicated and error-prone. Once the patient’s diet and living habits change, the settings such as insulin basal dose and pre-meal dose must be re-adjusted, and the above-mentioned complicated setting process must be repeated, which greatly limits insulin The use and promotion of the pump is also an important reason why it is expensive and can only be operated and used by doctors in hospitals.

After setting the number of segments, you can further set the total infusion dose and basal infusion rate in each segment step by step; after entering the temporary high-dose option, you can The dose and infusion basal rate required for the temporary bolus infusion mode are determined according to whether it is exercise or eating. The second-level menu of the charging option is divided into two options: motor reset and exhaust. Motor reset is the motor homing operation performed when the insulin solution in the liquid storage cartridge is used up, and the purpose is to install a new liquid storage cartridge; exhaust is Action performed after replacing a reservoir to purge air from the entire fluid line. The secondary menu of the review option is divided into review of the total dose of daily infusion, review of large doses of three meals, review of temporary doses, and review of exhaust times, which can help doctors and patients to keep abreast of the records of insulin infusion doses within a period of time. Control the situation so as to guide the formulation of infusion plans for patients in the future.
