Description

An adjustable chest and abdomen air cushion for prone position ventilation

technical field

The utility model relates to a medical and health care device, in particular to an adjustable chest and abdomen air cushion for prone position ventilation.

Background technique

Prone position ventilation is recognized as one of the effective conventional treatments for severe acute respiratory distress syndrome (ARDS). Patients with ARDS (PaO ₂ /FiO ₂ <100mmHg) should be ventilated in prone position during mechanical ventilation, but there are several problems in the implementation of prone position ventilation:

1. Tube-related adverse events are prone to occur. Patients with severe ARDS are in critical condition, and multiple tubes may be placed on the body, such as artificial airway, nasogastric (intestinal) tube, central venous catheter, indwelling urinary catheter, chest and abdominal catheter, and even bone traction frame etc. Patients are prone to adverse events such as tubing prolapse, compression, twisting, and folding during body position conversion;

2. Prone to pressure sores. Prone position ventilation lasts for a long time each time, and the incidence of pressure sores is high, which increases the suffering of patients, prolongs the length of hospital stay, and increases the cost of patients;

3. Poor effect of ventilation therapy. Since the abdomen cannot be effectively suspended, the movement of the diaphragm will be restricted after being squeezed, which is not conducive to the patient's breathing and affects the therapeutic effect;

4. It is difficult to take the prone position. When the patient changes from the supine or lateral position to the prone position, the operation is difficult and usually requires the cooperation of 5 people at the same time, which is time-consuming and laborious.

Aiming at the above-mentioned problems in prone position ventilation, the current clinical practice is to place pillows of different shapes on different parts of the patient’s body to keep the abdomen in the air and prevent pressure sores at bony prominences. However, all kinds of pillows are soft Pillow, and there is no cavity reserved for various pipelines, which is prone to pipeline folding and pressure. However, the soft pillow is prone to dislocation during turning over, and needs to be adjusted after turning over, which greatly increases the difficulty of taking the prone position, and is time-consuming and laborious. In order to prevent pressure sores, air mattresses are usually used clinically. However, the entire mattress of the air mattress currently used in clinical practice is on the same plane, and the inflation pressure of each part is the same. The lack of personalized design cannot meet the needs of different parts of the body. The requirement of choosing different inflation pressures cannot meet the requirements of keeping the abdomen in the air during ventilation in the prone position, nor can it meet the requirements of allowing different parts of the body to be pressurized in turn.

In order to ensure the safety of patients with prone position ventilation, improve the effect of ventilation therapy, prevent pressure sores, improve their comfort, and make the operation of prone position easy and standardized, a new type of air cushion is urgently expected to solve the above problems in clinical work.

Contents of the invention
