Description

Speed-control heating infusion management device

Technical Field

The utility model relates to a manager, in particular to a speed-control heating infusion management device.

Background

When in transfusion for illness, patients often feel cold even accompanied with shivering and other discomforts due to lack of effective transfusion heating means, and the subjective feeling is very poor. Meanwhile, when the disease is ill, the immunity of the organism is reduced, the activity of various enzymes is reduced, the circulation is reduced, if the body temperature is reduced, the peripheral blood supply is reduced, the immunity of the organism is further reduced, even the disease is delayed to be cured, aggravated and even accompanied by other diseases due to the reduction of the body temperature, and the disease is extremely unfavorable for patients. Hypothermia easily induces chill, myocardial ischemia, cardiovascular and cerebrovascular accidents, cerebral thrombosis, respiratory tract and gastrointestinal tract diseases. For a common infusion patient, infusion heating is the simplest and most effective method for improving the feeling of the patient and avoiding the temperature drop of the patient.

During operation, the infusion amount is usually obviously increased, and is one of the important reasons for the reduction of the body temperature of a patient during operation. Hypothermia not only makes patients feel cold, but also influences physiological functions of the patients, and makes the cardiovascular and cerebrovascular of the patients increase unexpectedly; the activity of blood platelet and prothrombin is reduced, and the surgical bleeding is increased; the immune function is reduced, and the postoperative infection probability is increased; the blood supply of the brain is reduced, cerebral thrombosis is easy to occur, and anesthesia awakening delay is easy to occur; hypothermia increases pulmonary blood flow, which is detrimental to oxygenation; the binding force of hemoglobin and oxygen is increased, which is easy to cause hypoxia and metabolic acidosis. A large amount of medical data prove that the core temperature of a patient needs to be kept above 36 ℃ in the operation, so that wound infection can be reduced, the occurrence of cardiovascular and cerebrovascular accidents is reduced, the fatality rate is reduced, and the number of hospitalization days can be shortened. Infusion warming is the most important means to prevent patient intraoperative temperature loss.

Meanwhile, in operation, rapid transfusion is needed under certain conditions, such as heavy bleeding and various insufficient volumes. At the moment, an effective speed-up means is lacked, the infusion is often manually extruded by emergency personnel, the efficiency is low, the speed is not accurate, and medical personnel are wasted.

In addition, at present, the infusion speed is judged clinically by adopting a visual method: the input volume (ml) per hour is equal to the number of drops per minute multiplied by 4; the number of drops per minute (gtt/min) — the total ml of input liquid ÷ [ total time of infusion (h) × 4 ]; the time (h) required for infusion is divided by the total ml of the input liquid (drop per minute. times.4). A stopwatch is needed during speed regulation, counting is carried out for at least half a minute, efficiency is low, and accuracy is poor. Meanwhile, the thicknesses of the infusion tubes on the market are not consistent; even if the infusion tubes of the same type have different inner diameters at different temperatures, the infusion speed is difficult to keep stable. The treatment effect is reduced due to too slow infusion, the time and the medical resources are wasted; improper infusion speed is too fast, which may cause heart failure and pulmonary edema of the patient, with more serious consequences. Accurate infusion speed is particularly important for pediatric patients.

The clinical urgent need is a can be swift accurate control infusion speed, can control the infusion temperature simultaneously, makes the infusion experience improve, and infusion efficiency increases, and infusion is safe and reliable.
