Cardiovascular patient nurses recovered apparatus

Technical Field

The invention belongs to the technical field of rehabilitation nursing equipment, and particularly relates to a cardiovascular patient nursing rehabilitation tool.

Background

A significant effort in the Interheart study, which was participated in by 52 countries, was published at the european cardiology society in 2004. Indicating that 90% of myocardial infarction can be predicted by 9 readily assessable risk factors: (1) abnormal blood lipid ratio (ApoB/ApoA-II); (2) smoking; (3) diabetes mellitus; (4) hypertension; (5) abdominal obesity; (6) tensioning; (7) daily lack of fruit, vegetable intake; (8) lack of motion; (9) drinking. Thus lifestyle changes can prevent most acute myocardial infarctions. Hygiene guidelines have shifted to the importance of prevention. Aerobic exercise, weight loss, prevention of obesity, influence on glycolipid metabolism, stress relief, etc., is associated with a number of risk factors for cardiovascular disease. Therefore, aerobic exercise has important significance for primary prevention and secondary prevention of cardiovascular diseases.

Exercise has long been considered as a forbidden area for heart disease, and cardiologists have given more orders to patients to take longer breaks, but this concept has changed drastically in recent years. Many scholars both at home and abroad have reported that exercise rehabilitation can prolong the life of patients and reduce the mortality rate. It is considered that appropriate exercise can not only prevent ischemic heart disease, but also be one of the main measures of cardiovascular diseases such as myocardial infarction, PTCA, CABG, congestive heart failure, etc.; proper exercise can increase the coordination of myocardial contraction, increase myocardial contractility and increase cardiac output. As energy and oxygen consumption are increased, weight is correspondingly reduced, and weight is effectively reduced, thereby reducing workload of the heart.

Because of the increase of energy and oxygen consumption during exercise, the normal breathing of some patients with cardiovascular diseases can not meet the aerobic requirement of the body, so oxygen is required to be inhaled during exercise; traditional recovered setting can only play the exercise effect, still needs oxygen bag or oxygen cylinder if the oxygen uptake, and it is very inconvenient to use, still needs to go the hospital filling, is not convenient for remove moreover.

Therefore, the invention is very necessary to develop a cardiovascular patient nursing and rehabilitation appliance.
