Description

Inflatable non-invasive ventilator mask

technical field

The utility model belongs to the technical field of medical equipment, in particular to an inflatable non-invasive ventilator mask.

Background technique

Non-invasive ventilation connects the patient with the ventilator through a mask, and is used for the treatment of acute respiratory failure. It is easy to operate, avoids endotracheal intubation and tracheotomy, and saves the patient from the pain of endotracheal intubation or tracheotomy. Reduce the complications associated with endotracheal intubation and its ventilator therapy, such as the incidence of ventilator-associated lung infection, difficulty weaning off after prolonged ventilator therapy, and prolonged hospital stay. In short, non-invasive ventilation is simple and easy, medical treatment and nursing are more convenient, the hospitalization time of patients is reduced, and medical expenses are reduced.

When using a non-invasive ventilator, the mask is the link between the patient and the ventilator, and the airtightness and comfort of the mask are directly related to the therapeutic effect. Then, the problem that often occurs in the actual use of the mask is air leakage or pressure on the facial skin. Air leakage will make the pressure in the mask less than the predetermined pressure and affect the therapeutic effect. Therefore, it is very important to eliminate air leakage. However, it is often thought that the tighter the headgear is, the less likely it is to cause air leakage, and this air leakage problem can be solved , In fact, this is not the case. On the contrary, not only the air leakage phenomenon has not been eliminated, but local indentations or skin redness may appear on the face due to excessive compression, and severe skin ulcers may also occur.

In order to solve the problem of pressure sores on the face caused by masks, Patent No. CN201410102028.6 discloses a ventilator mask pad. The mask pad is composed of a nose pad and an oral pad. The "herringbone" shape structure adapted to the side. The mouth pad is composed of a support pad and a covering layer. The support pad is in an arc-shaped structure suitable for the mouth of the human body. The edge is fixedly connected with the support pad, and the two tails of the herringbone structure of the nose pad and the two tails of the arc structure of the support pad are provided with a nylon adhesive layer that cooperates with each other, and the nose pad and the mouth pad pass through the nylon adhesive layer Butt into the mask cushion as described. The ventilator mask cushion is placed between the mask and the face to effectively prevent pressure sores on the face, but the mask and the ventilator mask cushion are designed separately, which is inconvenient to use and increases the labor intensity of the nursing staff.

Because the existing mask does not have a gastric tube insertion port, the usual method is: 1. The gastric tube is coiled in the mask, which will increase the airflow resistance and bring discomfort to the patient. 2. Place the gastric tube outside the mask, but the mask has to be tightly pressed against the gastric tube to prevent air leakage, so that the patient will have a strong sense of oppression, which also brings discomfort to the patient, and the facial skin will be damaged after a long time There will be redness, swelling, crushing, even ulceration and infection; at the same time, no matter how tight the pressure is, the mask will leak, which will lead to a decline in the efficacy of the non-invasive ventilator. In order to solve the technical problem of gastric tube insertion, a non-invasive ventilator mask disclosed in Patent No. 201420529836.6 includes a mask shell, and the upper surface of the mask shell is provided with a ventilator ventilation tube connector, a nasogastric tube insertion port and a liquid diet insertion port , its side surface is provided with an elastic fixing belt interface for fixing it to the patient's head, and it is characterized in that: a decompression patch is provided on the part of the mask shell that is in contact with the patient's face, and the decompression patch is filled with elastic It is composed of an outer cover covered with material and elastic filler, one side of the outer cover is provided with a pressure-sensitive adhesive layer to fix it on the patient's face, and the other side is provided with an elastic sleeve to fix it on the mask shell. This patent directly inserts the gastric tube by setting the nasogastric tube insertion port on the mask shell, but the actual gastric tube head is larger than the tube of the gastric tube, so in order to ensure that the gastric tube head can be inserted from the nasogastric tube insertion port, the nasal The size of the gastric tube insertion port must be consistent with the size of the gastric tube head, and after the gastric tube head is inserted into the patient's nose, the gastric tube tube is at the insertion port of the nasogastric tube, which will cause the gas in the mask to be inserted from the nasogastric tube Mouth leaks.

In addition, because the existing masks do not have insertion ports for sputum suction tubes and drinking water tubes, etc., when patients suck sputum or drink water, they need to remove the mask before sucking sputum or drinking water, etc., resulting in deoxygenation in the middle of the patient, which will cause hypoxia in the patient. Produce tissue damage and dysfunction, affect the normal treatment of patients, and increase the labor intensity of nursing staff.
