Oxygen mask suitable for being used after nasal cavity operation

Abstract

An oxygen mask suitable for being used after a nasal cavity operation comprises a mask body, the mask body is provided with connecting holes, an oxygen inhalation position, a nose support position and a lower jaw support position, a through oxygen inhalation hole is formed in the oxygen inhalation position, a connecting pipe head is fixed to the position, located on the outer side of the oxygen inhalation hole, of the mask body, and the connecting pipe head is used for being connected with an oxygen inhalation pipe connector; the nose support position and the lower jaw support position are used for being attached to the outer sides of the nose bridge and the lower jaw of the face respectively; the mask body is located at the two connecting holes and can be attached to the portion, close to the ears, of the face; and the inner side of the mask body gradually expands outwards from the oxygen inhalation position to the connecting hole position, the nose support position and the lower jaw support position to form a semi-open petal shape. Open petal-shaped design is adopted, due to the fact that the nasal cavity of a patient is filled after a nasal cavity operation, a double-nasal-cavity oxygen inhalation pipe cannot be used, and most patients breathe through the mouth, the semi-open petal-shaped oxygen mask design provides enough breathing space for the patients, discomfort symptoms such as oppressed feeling of the patients are relieved, and psychological burdens of the patients are relieved.

Description

technical field [0001] The invention relates to medical equipment, in particular to an oxygen mask suitable for use after nasal cavity surgery. Background technique [0002] Pituitary tumor is a common benign tumor type in neurosurgery ［1］ , accounting for 16.7% of the total incidence of intracranial tumors ［２］ . The transsphenoidal approach has become a common resection method for this type of tumor due to its advantages of low trauma, rapid recovery, low recurrence rate, and easy acceptance by patients ［3-4］ . [0003] Most of the patients still use Vaseline gauze, expansion sponge, iodophor gauze, silicone tube, absorbent cotton and other materials to stuff the nasal cavity after nasal endoscopic surgery to prevent bleeding, nasal adhesion and other complications. [5-7] . The main purpose of nasal surgery is to improve the quality of life of patients, however, nasal packing brings more discomfort to patients [8] . [0004] Under normal circumstances, the outside ai...

Problems solved by technology

[0008] ①Double-plug method—two smaller nasal plugs are placed in both nostrils at the same time. There is still a space around the nasal plugs, and the air can be breathed at the same time. The patient is more comfortable, but the oxygen concentration is not stable enough

Due to the stuffing of the patient's nasal cavity after nasal cavity surgery, the nasal dual-channel oxygen inhalation method cannot be used for oxygen supply, and the conventionally used oxygen mask is designed for patients who breathe through the nasal cavity and does not reserve enough oral breathing space in the oral cavity. Oxygen masks are less comfortable for patients with nasal congestion, and it is easy to increase patients' discomfort such as oppressive feeling.
