Description

Technical Field

[0001] The present invention belongs to the technical field of heart failure treatment, and in particular relates to an implantable heart failure treatment device. Background Art

[0002] Heart failure (HF) is a disease caused by abnormal cardiac pumping function, which results in the heart's inability to meet the body's basic metabolic needs. Common causes include myocardial infarction, cardiomyopathy, myocarditis, etc. The high-risk population includes the elderly over 70 years old, with an incidence rate of more than 10% and a 5-year mortality rate of up to 50%. Heart failure can be divided into left heart failure, right heart failure and total heart failure according to the site of the lesion. The main symptoms of heart failure include dyspnea, limited movement and fluid retention. When the condition worsens, symptoms such as pulmonary congestion, shortness of breath, chest tightness, lower limb edema, fatigue and dizziness may occur.

[0003] Methods for treating heart failure include drug therapy, cardiac resynchronization therapy (CRT) and implantable cardioverter defibrillator (ICD). Normal living habits and diet control are also very important parts of the treatment process.

[0004] During the treatment of heart failure patients, a heart failure treatment device is generally implanted on the surface of the heart of the patient in order to synchronize the contraction of the heart, improve the heart's pumping function, automatically deliver electric shocks for defibrillation, and restore normal heart rhythm.

[0005] Most existing heart failure treatment devices, after being implanted on the surface of the patient's heart, monitor, treat and record the patient's heart through a processor and various sensors, making it easier for medical staff to observe the heart condition of heart failure patients and allowing doctors to adjust the treatment methods for heart failure patients.

[0006] However, although most heart failure treatment devices can monitor the condition of heart failure patients in real time and respond quickly during use, in the process of treating heart failure patients, it is necessary not only to defibrillate the patients through the heart failure treatment devices to restore their normal heart rate, but also to give them medication so that they can recover to normal more quickly.

[0007] However, most of the existing heart failure treatment devices are unable to automatically administer drugs, and still use traditional manual drug administration, which results in the inability to ensure timely drug administration during the treatment of heart failure patients, which may lead to untimely treatment of patients and affect the treatment of heart failure patients, threatening the lives of heart failure patients. Therefore, there is a problem in the existing technology that it is not convenient to automatically administer drugs to patients in a timely manner. Summary of the invention

Preferably, the temperature sensor 414 in the present application can select an infrared temperature sensor 414.

[0052] The electrode assembly 1 further includes a motion sensor 102 and a physiological parameter sensor 103, both of which are mounted on the upper surface of the electrode plate 101, and a heart pressure monitor 104 is fixed on the lower surface of the electrode plate 101;

By setting the main rod 201 and the auxiliary rod 202, when the electrode assembly 1 and the treatment body 3 are offset, the main rod 201 and the auxiliary rod 202 slide relative to each other, reducing the influence of the pulling force on the treatment body 3 and the electrode assembly 1, and avoiding the displacement of the position of the electrode assembly 1 due to the relatively fixed setting of the adjustment mechanism 2.
