Problems solved by technology

However, when using this traditional method of manually pushing the medicine, the medicine liquid will follow the blood flow direction in the blood vessel to all parts of the body after entering the blood vessel, which cannot be compared with the patient's blood pressure value, heart rate, etc., which will respond to the patient's own adjustment mechanism. The parameters are connected, so that only part of the liquid medicine enters the tumor blood vessels, resulting in the result that the liquid medicine kills both cancer cells and normal cells; It will also cause many clinical problems, which will not only increase the financial burden of patients, but also increase the workload of medical staff.

Embodiment

[0038] A predictive adaptive control system for liquid medicine bolus injection, such as figure 1 As shown, it includes a main control module and a medicinal solution injection module. The main control module includes a detection module for collecting human blood pressure values. The detection module transmits the blood pressure values ​​to the memory area for storage to form an array of blood pressure values. The memory area is connected with an identification module, and the identification module identifies the array of blood pressure values ​​in the memory area to obtain the real-time cardiac cycle and the characteristic parameters in the cycle. The identification module is also connected with a predictive control algorithm module, and the predictive control algorithm module The injection time of the next cardiac cycle is obtained by calculating the characteristic parameters;

Abstract

The invention discloses a predictive adaptive control method and a predictive adaptive system for liquid medicament push-injecting, and relates to the technical field of automatic control of the liquid medicament push-injecting in clinical surgery. The predictive adaptive control method for injecting the liquid medicament provided by the invention comprises the following steps of: (1) acquiring a blood pressure value; (2) obtaining related parameters; (3) calculating liquid medicament injecting time; (4) starting a liquid medicament injecting module; and (5) self-adapting the push-injection. In the method and the system, the liquid medicament push-injecting speed, the push-injecting time, the push-injecting stop time and the liquid medicament push-injecting amount in the liquid medicament injecting module are controlled by a master control module, so that the response speed and the real-time control capability of the liquid medicament push-injecting module are improved; the scientific, reasonable and safe medicament application is realized, namely local organs obtain maximum medicament concentration and the maximum medicament concentration remains long enough time without backflow by little medicament dose; and therefore, the damage to healthy tissue is reduced.

Description

technical field [0001] The invention relates to the technical field of automatic control of medicine pushing in clinical operations, in particular to a predictive self-adaptive control system for medicine liquid injection. Background technique [0002] At present, in the clinical treatment of cancer, chemotherapy through vascular intervention is commonly used, that is, puncture and catheterization under the monitoring of digital subtraction X-ray machine (DSA), and the catheter is introduced into the entrance of the branch of the tumor blood supply artery. , inject chemotherapy drugs at the inlet end of the catheter. This method was first used for cardiovascular diseases, and was soon applied to the diagnosis and treatment of various diseases in various parts of the body, such as the nervous system and tumors. In my country, interventional therapy is especially used for tumors, accounting for the majority of interventional therapy, and has become a commonly used therapy in ...
