Description

Anesthetic mask
Technical Field
The invention belongs to the technical field of medical instruments, and particularly relates to an anaesthetic mask.
Background
When a patient is subjected to a large-scale operation, anesthesia is firstly carried out, and inhalation anesthesia is usually carried out by means of an anesthesia mask, so that the patient is free from the painful experience in the operation. When covering the face guard in the oronasal department of disease and giving oxygen and carrying out the narcotic administration, it has fine leakproofness to guarantee that face guard and patient's face generally has, can guarantee on the one hand so that the narcotic can not expose and cause the waste, and protect medical staff can not inhale the narcotic by mistake, in addition good leakproofness also can guarantee when giving patient's oxygen suppliment, the sufficient of oxygen is given, if there is gas leakage phenomenon, not only influence the anesthesia effect, also can make when anesthesia induction pressurization oxygen suppliment, the oxygen suppliment is not enough, hypoxemia appears, lead to unnecessary medical affairs.
However, in clinical practice, some diseases often cause poor air tightness of the mask in the anesthesia process because the face and the anesthesia mask cannot be well attached, for example, teeth of some old people fall off, or the diseases are too thin, or the two sides of the face are sunken because the stomach tube is arranged on the face, the face is difficult to attach to the bottom air bag of the common anesthesia mask on the market, and then the air leakage phenomenon is caused.
At present, the Chinese published patent of 'leak-proof anaesthetic mask' (publication number: CN201807050U) has elliptical leak-proof air bags respectively arranged on two sides of the air bag of the mask close to the lower jaw end of the mask, and the size of the leak-proof air bag is adjusted to be matched with the cheek shape of a patient, thereby preventing air leakage.
As a new type of multifunctional mask for anesthesia department (publication No. CN204395183U), the bottom of the mask is provided with an air bag through an air bag cushion layer, two auxiliary air bags are arranged in the air bag, the outer wall of the air bag is provided with an adjusting hole, and the air bag cushion layer, the auxiliary air bag and an air exhaust hole which are sticky are arranged on the outer wall of the air bag, so that the problem that the existing mask is easy to leak air is solved.
However, in both of the above two kinds of anesthetic masks, the two sides of the depressed face of the patient are only compensated by adding two auxiliary small airbags to the cheek of the patient, in practical use, the face shapes of the patients are different, the shapes of the auxiliary small airbags are limited to a certain extent, the auxiliary small airbags cannot be well adapted to various face curves of the patients, the auxiliary small airbags are still not suitable for some patients, and the air leakage phenomenon still often occurs.
In addition, the fixing rope of the current anaesthetic mask is generally fixed in position, sometimes when the anaesthetic mask is fixed on a patient with head trauma, the fixing path is difficult to select, but good fixing needs a certain fastening degree, and the phenomenon of pressing the wound is inevitable at this time, which brings unnecessary pain to the patient.
Disclosure of Invention
