Description
技术领域technical field
本发明涉及溶液配制技术领域,具体地,涉及一种基于往复驱动装置的溶液配制及注射系统。The invention relates to the technical field of solution preparation, in particular to a solution preparation and injection system based on a reciprocating drive device.
背景技术Background technique
注射是指借助注射器一类的医疗器械将液体或气体注入人体,以达到诊断、治疗、预防疾病的目的,其与吃药不一样,药液经注射后可迅速到达血液并产生作用。药液经注射后可迅速到达血液并产生作用,但万一误用则药物不易清除,注射时有疼痛感,注射部位有时发生局部不良反应。Injection refers to injecting liquid or gas into the human body with the help of a medical device such as a syringe to achieve the purpose of diagnosis, treatment and prevention of diseases. After injection, the medicinal liquid can quickly reach the blood and have an effect, but in case of misuse, the medicine is not easy to be removed, and the injection is painful, and local adverse reactions sometimes occur at the injection site.
现有医疗技术领域,许多病人需要长期注射药物,以维持正常的生活,因此,病人需要花费大量的时间定期到医院注射,同时,医护人员也要定期花费大量的时间进行手工配药,其中,配药的过程中劳动强度大,效率低下,且容易操作失误,既浪费了病人和医护人员的时间,而且还存在不安全因素;尤其是对于许多药液的配制要求比较苛刻,各种药液的配制比例要求严格,因此给人工配制药液带来了更大的挑战。In the existing medical technology field, many patients need to inject drugs for a long time to maintain a normal life. Therefore, patients need to spend a lot of time in the hospital for injections on a regular basis. At the same time, medical staff also spend a lot of time on manual dispensing. It is labor-intensive, low-efficiency, and prone to operational errors during the process, which not only wastes the time of patients and medical staff, but also has unsafe factors; The ratio requirements are strict, which brings greater challenges to the manual preparation of liquids.
专利文献CN209154758U公开了一种智能注射系统,通过连续血糖监测仪获取用户的血糖值,并通过无线连接模块发送至单片机,所述单片机将所述血糖值发送至所述液晶显示屏显示,使用户能够实时获知自己当前的血糖值,当血糖值高于正常水平时,通过按键发送指令给所述单片机,所述单片机接收所述按键的指令控制所述第一电机驱动电路驱动所述双管注射泵注射胰岛素,当血糖值低于正常水平时,通过按键发送指令给所述单片机,所述单片机接收所述按键的指令控制所述第二电机驱动电路驱动所述双管注射泵注射胰高血糖素,从而能够实时监测和显示糖尿病患者的血糖值,并通过按键即时注射胰岛素或胰高血糖素维持体内血糖平衡,保证糖尿病患者的安全,但该设计不能实现多种药液配制的情况,且完全基于电能,有噪音。Patent document CN209154758U discloses an intelligent injection system, which acquires the user's blood glucose value through a continuous blood glucose monitor, and sends it to a single-chip microcomputer through a wireless connection module. It can know its current blood sugar level in real time. When the blood sugar level is higher than the normal level, it sends an instruction to the single-chip microcomputer through the button, and the single-chip computer receives the instruction of the button and controls the first motor drive circuit to drive the double-tube injection. The pump injects insulin, and when the blood sugar level is lower than the normal level, it sends an instruction to the single-chip microcomputer through the button, and the single-chip computer receives the instruction of the button and controls the second motor drive circuit to drive the double-tube syringe pump to inject glucagon. In this way, the blood sugar level of diabetic patients can be monitored and displayed in real time, and insulin or glucagon can be injected instantly to maintain the blood sugar balance in the body to ensure the safety of diabetic patients. However, this design cannot realize the preparation of multiple liquid medicines, and Entirely based on electrical energy and noisy.
