Embodiment Construction

[0060] To implement the present invention in detail, it is necessary to press the technical scheme of the present invention ( Image 6 shown), first build a hardware platform, and then insert the online blood pressure measurement component, predictive control component, drive micro-injection component, operation process, and display component described in the claim.

[0061] The construction of the hardware platform adopts the foolish "assembly method" of "checking the number of seats", and does not require the implementers to achieve the multidisciplinary basic theoretical knowledge and skills that the inventor should have. After the built-in self-diagnosis runs normally, it can be put into operation after calibration (blood pressure, time, nonlinear adaptability and real-time performance, etc.). Considering the professional limitations of hospital operation personnel and doctors, the present invention relates to the lack of basic theory and engineering technology basic knowl...

Abstract

The invention relates to a 'haemodynamics-based forecast self-adaptive automatic injection device', which consists of functional units such as a microcomputer system, a multifunctional interface card, a blood pressuresensor, a weak signal amplifier, a trace controller, a trace injector, a medical injector and the like. The device can detect the physiological blood pressure parameters of patients on line in real time, identify cardiac cycles and time phases automatically, and perform trace injection quantitatively and automatically at constant speed in a certain time period in each cardiac cycle according to injection modes selected by doctors. In the injection process, the time phase, speed and dose of the injection in each cardiac cycle are corrected automatically according to the blood pressure parameters, which are monitored in real time, of the patients to 'guide' the finite amount of liquid medicine which is free in pulsation blood to enter pathological change positions as much as possible, so that the maximum medicinal concentration is obtained, the bioavailability of medicines is improved, and the total amount of the medicines and toxic and side effects are reduced. After the injection is finished, the operation information of the patients is recorded automatically and is stored into a database for inquiry and remote access.

Description

technical field [0001] The invention belongs to an automatic control instrument for pushing medicine in clinical operations. It is an intelligent automatic drug push control device used in the injection of cancer chemotherapy drugs in clinical interventional operations. It is a drug pushing device that involves the interdisciplinary technology of cardiovascular hemodynamics, electricity, clinical medicine and computer science. Background technique [0002] A research report published at the 18th World Health Organization International Anti-Cancer Union Congress stated that the global cancer situation is getting worse, the number of new patients will increase from the current 10 million to 15 million per year in the next 20 years, and the number of deaths due to cancer will also increase. Will increase from 6 million to 10 million per year. Cancer has become the number one killer of human beings in the new century and will become the biggest public health problem in the wor...
