Abstract

The utility model relates to the technical field of medical equipment, and in particular to an inflatable chest belt. It comprises a chest belt body and an airbag. The chest belt body is used to surround the patient's chest and be fixed on the back; there are multiple airbags, which are detachably mounted on the outside of the chest belt body, located at symmetrical positions on both sides of the sternum, and are used to support patients in a prone position; the top of the airbag is a plane, and the multiple airbags are respectively provided with vents, and each vent is provided with a valve for controlling the inflation and deflation of the airbag. The chest belt of the prior art only plays the role of fixing and protecting, and cannot effectively support the patient's chest. There is still pressure on the chest during ventilation in the prone position, which may affect the patient's breathing and blood circulation. In addition, the fixing device of the existing chest belt is relatively complicated and requires multiple adjustments and disassembly, which is not conducive to the patient's turning over and nursing.

Inflatable chest strap

Technical Field

The utility model relates to the technical field of medical equipment, in particular to an inflatable chest strap.

Background

Cardiac surgery is a common method of treating heart disease, but there are many risks and challenges in the procedure. First, cardiac surgical procedures are complex, time consuming, and often require procedures to be performed at low temperatures, all of which increase the likelihood of complications such as patient temperature drop, reduced blood flow, hypoxia, etc. Secondly, due to the influence of factors such as anesthesia, the patient is extremely easy to suffer from hypoxia after operation, namely, the number of red blood cells carrying oxygen in blood is insufficient, so that oxygen is deficient in all parts of the body. Hypoxia can lead to serious consequences such as prolonged mechanical ventilation time for the patient, increased post-operative mortality, and an impact on the patient's quality of life. The incidence rate can reach 51% in some researches.

In order to improve the hypoxemia condition of patients, prone position ventilation is an important therapeutic measure. Prone position ventilation refers to placing a patient in a prone position, i.e., face down, back up, to improve lung ventilation/blood flow ratio by gravity, increase alveolar ventilation, and increase arterial blood oxygen partial pressure. However, prone position ventilation also presents a certain risk and inconvenience to patients after cardiac surgery who have a median sternal incision. Because the chest is a very easily extruded part in the prone position, if proper protection measures are not taken, the prone position ventilation can cause compression and stimulation to the chest wound, and complications such as wound infection, bleeding, dehiscence, displacement and the like are caused.

In order to prevent compression of chest wounds during prone ventilation, chest bands specifically designed for patients after cardiac surgery are currently available. For example, CN205215522U discloses a post-operative elastic chest band for the heart. The chest strap comprises a chest strap body made of elastic material and a fixing device. The chest strap body is used for surrounding the chest of a patient and is fixed on the back of the chest strap body; the fixing device is used for fixing the chest strap body in a proper position.

However, the chest strap serves only a fixing and protecting function and does not effectively support the chest of the patient, and pressure on the chest still exists when ventilation is performed in the prone position, which may affect the breathing and blood circulation of the patient. In addition, the fixing device of the prior chest belt is complex, needs to be adjusted and detached for many times, and is not beneficial to the turning over and nursing of patients.
