Description

Alarm reminding device for measuring angle of bedside

Technical Field

The utility model relates to a medical treatment auxiliary assembly technical field especially relates to a warning reminding device to bedside angle measurement.

Background

Given that Ventilator Associated Pneumonia (VAP) is a particular type of nosocomial pneumonia that occurs 48h after mechanical ventilation, reflux and aspiration are considered to be important causes of many of the VAPs in patients, aspiration of infected oral and gastric secretions, including both dominant and recessive, is considered to be a major cause in the etiology of VAP, with aspiration being an independent factor in the etiology. Patient position can affect gastric content reflux and therefore VAP infection rate. And related researches prove that the incidence of VAP can be effectively reduced by adjusting the angle of the bed head to 30-45 degrees, and the effect below 30 degrees is not obvious. The diagnosis and treatment guidelines for pneumonia related to breathing machine and acquired pneumonia in Chinese adult hospital are definitely proposed in 2018: for mechanically ventilated patients, the bed head should be raised by more than 30 degrees without contraindications, and the effect of raising the bed head by more than 30 degrees on reducing VAP by mechanically ventilated patients is better than that of raising the bed head by less than or equal to 30 degrees. However, the research evidence at home and abroad shows that the higher the bed head is, the better the bed head is, the higher the bed head is, the risk of pressure injury, hypotension and high IAP (platelet aggregation protein) can be increased when the elevated bed head is used for preventing VAP (VAP), the influence of the body position on intracranial pressure and cerebral perfusion pressure is also considered for patients with craniocerebral diseases, and the elevation angle of the bed head for ICU (intensive care unit) patients is also closely related to hemodynamics. Thus a 30 elevation of the head of the bed may be a compromise between the conflicting recommendations for VAP prevention and other adverse effects, while in a related study of intra-abdominal pressure it was found that 30 may be the best position to maintain proper IAP and prevent VAP. The posture of the patient can be adjusted by adjusting the angle of the bed head, and the pillow has positive clinical significance for patients suffering from asthma, nasal feeding, cerebral apoplexy, abdominal diseases or brain diseases and the like.
