Description

Multifunctional perioperative patient uses intelligent heat preservation device

Technical Field

The invention relates to the technical field of operation auxiliary equipment, in particular to a multifunctional perioperative patient intelligent heat preservation device.

Background

Body temperature, blood pressure, pulse, respiration and pain together make up five vital signs. Keeping body temperature constant is a necessary condition for ensuring body metabolism and normal life activities. The phenomenon of body core body temperature below 36 ℃ due to various causes during perioperative period is called perioperative hypothermia. According to the general knowledge of hypothermia prevention and treatment experts of perioperative patients (2017) jointly issued by the national anesthesia professional quality control center and the anesthesia academic society of the Chinese medical society, the incidence rate of hypothermia of perioperative patients is high (7% -90%), the reported data of the Beijing area in 2015 is 39.9%, and the cross section survey reported data of the national part of the area in 2017 is 44.5%.

The temperature in the operating room is generally kept at 22-25 ℃ which is more suitable for human bodies. However, such temperatures are relatively low during surgery, especially for patients under anesthesia. First, the patient undergoing the procedure wears a thin drape, and the surgical drape does not completely cover the patient. Secondly, the heat loss in the body cavity is larger when the operation incision is exposed, especially when the operation is performed for opening the abdomen and the chest. Again, the procedure may infuse large amounts of fluids, blood products, etc., and also lower the temperature of the patient. In addition, the voluntary thermogenic function is lost due to the relaxation of the patient's skeletal muscles during anesthesia.

Abnormal body temperature can cause metabolic dysfunction and even be life threatening. Perioperative hypothermia can lead to a number of adverse outcomes, such as: perioperative hypothermia increases the incidence of perioperative cardiovascular adverse events (ventricular arrhythmias, myocardial ischemia, post-operative myocardial infarction); increase the infection rate of surgical wounds, prolong the stitch removing time of the wounds and prolong the hospitalization time; coagulation/fibrinolysis dysfunction; transfusion demand increases; changes the efficacy and metabolism of the anesthetic, delays the postoperative recovery of the patient, prolongs the stay time, increases the discomfort of shivering and the like.

At present, the most common clinical patient body surface warming device is an inflatable warm air blanket (forced-air warming blanket), and domestic and foreign literature reports show that the warming device is a safe, effective and widely used heat preservation device. But limitations of its use can also be found from our clinical application. Firstly, the inflatable heat preservation blanket is a hollow blanket which is covered on the body surface of a patient and contains a plurality of small holes by the heated air filled by the host machine. The accelerated hot air may rush to the surgical field, contaminating the surgical field. Second, for small and short-term surgery, the inflatable thermal blanket has a good thermal insulation effect, but for large surgery (such as liver transplantation), the thermal insulation effect is not ideal, and multiple thermal blankets may be needed together. Thirdly, the host of the warming blanket has larger volume and generates obvious noise during working. Fourthly, the heat-insulating blanket is a disposable article, which can not be repeatedly sterilized, thus increasing the medical expense of patients and polluting the environment. Therefore, clinically, a perioperative heat preservation device which has good heat preservation effect, is far away from an operation area, has small volume and low noise and is environment-friendly is urgently needed.

In addition, perioperative venous thrombosis also occurs at a very high rate, especially in the deep veins of the lower extremities. If the venous thrombus is shed, it can move with the blood flow and block the blood vessel, causing pulmonary embolism, myocardial infarction, cerebral infarction, and even sudden death. However, the lower limbs of the patients can not move during the operation, and the venous blood flow is stagnated, especially for the patients who have long-term major operations. The intermittent inflation pressurization treatment can obviously play a role in preventing the venous thrombosis. The volume of the intermittent inflation and pressurization treatment machine used clinically at present is also large, which causes great inconvenience to an operating room with limited space.

Therefore, the multifunctional device with the functions of intraoperative heat preservation and intermittent pressurization and inflation can improve the perioperative treatment effect of the patient, reduce complications, improve the safety and reduce the medical expense.
