Description

A new type of oxygen mask

technical field

The utility model relates to the technical field of medical appliances, in particular to a novel oxygen mask.

Background technique

Oxygen masks provide a way to transfer the oxygen needed for breathing from a storage tank to the human lungs. There are mainly medical oxygen masks, aviation oxygen masks, and oxygen masks used by airline passengers, which play an important role in treating diseases and protecting the safety of passengers and pilots. Oxygen masks are mainly made of plastic, silicone, or rubber, and are mainly used for oxygen delivery for patients with dyspnea and hypoxia. The oxygen mask is composed of a mask, an oxygen storage bag, a T-shaped tee, an oxygen delivery catheter and a fixed component. When in use, oxygen is directly injected into the oxygen storage bag, and then the mask is placed on the patient's face to seal the mouth and nose. The mask is fixed to the patient's head using a fixing member for oxygen inhalation. However, there are still various problems with various oxygen-inserted masks on the market.

For example, an oxygen mask disclosed by the authorization announcement number CN 208436207 U, although the safety of oxygen inhalation for critically ill patients has been improved, it has not solved the problem that the oxygen mask is made of plastic. Fixed later. In the medical process, if an oxygen mask is needed, it is usually because the patient is seriously ill and the blood oxygen saturation is low, and oxygen needs to be supplied through an oxygen mask. However, the existing ordinary plastic oxygen mask is not only hard, but also It is suitable for the face shape of each patient, and the size of some oxygen masks is not suitable. Often during use, the oxygen leakage is serious because the oxygen mask does not fit the patient's face and nose, which not only wastes oxygen resources, but also fails to achieve Effective oxygen inhalation seriously affects the development of the patient's condition, and the edge of the oxygen mask is hard, and it is easy to form pressure ulcers when it is attached to the cheek. To cause the problem of skin damage behind the ear, we propose a new type of oxygen mask.

The wing of the nose can be opened outward, and the nose pad 20 can be attached to the bridge of the nose to reduce the discomfort of the bridge of the nose. When the mask is fixed by the fixing rope 2, the non-woven fabric 23 on the protective cover 21 and the back of the ear The skin is close to the skin, which can not only reduce the appliance pressure sore on the skin behind the ear, but also make it more breathable and comfortable.

In summary, the new oxygen mask, through the design of the mandibular position adjustment mechanism, the cheek position adjustment mechanism and the nose alar position adjustment mechanism, enables the nose, cheeks, mandibles and other facial edges to be shaped according to the patient's face shape, and the patient's face. It is fully fitted to avoid air leakage, and the material is soft to avoid the formation of appliance pressure ulcers. Among them, the increased design of the mandibular inner gasket 8 increases the softness and comfort of the contact between the mandible and the mandibular outer gasket 7 , Through the design of the first limit bar hole 17 and the limit bar block 18, the two adjacent cheek pads 16 are prevented from being separated from each other when the sliding between the cheek pads 16 is realized. It is convenient to avoid damage to the skin behind the ear caused by the ordinary fixing belt. The design of the foam dressing 22 can prevent pressure sores, and the design of the non-woven fabric 23 can breathe and absorb sweat, which increases the comfort of use.
