Breathing mask and manufacturing method thereof

Abstract

The invention relates to the technical field of masks and discloses a breathing mask and a manufacturing method thereof. The breathing mask comprises a framework, a mask body and a connector used forbeing connected with a pipeline; the framework comprises a fitting part; the fitting part can be attached to the face; the mask body covers the fitting part, so that the fitting part can support the fitting position of the mask body and the face; and the mask body is provided with a through hole, and the connector is installed on the edge of the through hole, so that the interior of the mask bodycan be communicated with the pipeline. According to the breathing mask and the manufacturing method thereof, by arranging the framework, when medical staff implement positive pressure ventilation to assist breathing and press the breathing mask, the breathing mask can be attached to the face of a patient, air leakage is reduced, and therefore the ventilation assisting effect is improved.

Description

technical field [0001] The invention relates to the technical field of masks, in particular to a breathing mask and a manufacturing method thereof. Background technique [0002] During the induction and recovery of general anesthesia, the breathing mask covers the patient's mouth and nose, and the pipeline on the breathing mask is connected to the anesthesia machine to achieve the purpose of breathing support. During mask pressurization ventilation, the medical staff presses the mask to provide positive pressure ventilation to the patient to assist breathing. However, the existing breathing masks are all made of plastic, and the contact surface between the mask and the patient is a fixed frame, so that the mask cannot fit the face of some patients, and air leakage occurs, resulting in poor effect of positive pressure ventilation to assist breathing. In critically ill patients, the poor ventilation effect may even cause hypoxemia, leading to medical accidents. [0003] At p...

Problems solved by technology

However, the existing breathing masks are all made of plastic, and the contact surface between the mask and the patient is a fixed frame, so that the mask cannot fit the face of some patients, and air leakage occurs, resulting in poor effect of positive pressure ventilation to assist breathing. In critically ill patients, the poor ventilation effect may even cause hypoxemia, leading to medical accidents

[0003] At present, a number of patents have been dedicated to solving this problem. For example, Chinese patent CN107263856A discloses a 3D printed medical mask for a sleep apnea machine and its manufacturing method. , there will be micro-cracks of 6-8 μm on the surface of the mask body, and there is still a risk of air leakage; and the mask frame, silicone card and silicone pad are all made of 3D printing, the economic cost is high, and they cannot be reused between different patients, increasing the risk of air leakage. medical costs

Chinese patent CN209996976U discloses a 3D printed medical mask and a non-invasive positive pressure ventilation machine composed of it. Although the mask is considered to adapt to the shape of the face, it does not consider the shape of the patient's bones
