Respiratory mask and guide connecting member thereof

Abstract

The present invention relates to a respiratory mask and a guide connecting member thereof. The respiratory mask comprises a mask body, an air duct and the guide connecting member. The mask body includes an air inlet and a through hole close to the air inlet, wherein the air duct is connected with the air inlet and is used to transmit air into the air inlet. The guide connecting member comprises aplug body installed to the through hole and a sealing plug connected with the plug body, wherein the plug body includes an annular elastic retaining piece which defines an insertion aperture and a first fracture line extending from the inner rim to the outer rim to make the insertion aperture opened up for external expansion. A conduit is inserted in the insertion hole and is clamped by the elastic retaining piece. The sealing plug is inserted in the insertion hole in a detachable manner to seal the insertion hole.

Description

technical field [0001] The invention relates to a breathing mask, in particular to a breathing mask for installing a catheter. Background technique [0002] For patients with chronic obstructive pulmonary disease (COPD) or other patients with breathing difficulties caused by respiratory failure, the commonly used treatment methods are intubation, tracheotomy intubation or wearing a mask, and the positive pressure of the mask is used to ventilate the patient. It is a non-invasive ventilation (Non-invasive Ventilation, NIV) method, through the long-term use of face mask ventilation by patients who need to pump sputum or use nasogastric tube, because it must continuously provide stable positive pressure ventilation For patients, the design of the mask should not have any doubts about air leakage. [0003] refer to figure 1 and figure 2 , is a kind of respiratory mask 1 convenient for nasal feeding and sputum suction disclosed by the Chinese Utility Model Patent No. CN282976...

AI Technical Summary

Problems solved by technology

[0004] Yet in fact the aperture size of nasogastric tube can be different because of patient's situation, therefore, for the design of sealing plug pair 13 of above-mentioned respiratory mask 1, will not be able to fit the nasogastric tube with each aperture size different elastically, However, it may happen that the nasogastric tube aperture is too large to be inserted into the insertion hole 150, or the nasogastric tube aperture is too small and is easy to loosen and slip from the insertion hole 150, so as to cause inconvenience in use and air leakage.

Moreover, the patient does not need to insert the nasogastric tube at the sealing plug pair 13 of the respiratory mask 1 and removes the nasogastric tube, the insertion hole 150 of the sealing plug cover 132 of the sealing plug pair 13 will leak air, and must Replacement of a sealing plug cover 132' without an insertion hole 150 such as the sealing plug pair 13', such a design structure undoubtedly causes another inconvenience in use, and air leakage is prone to occur during the replacement process

[0005] This shows that above-mentioned existing breathing mask obviously still has inconvenience and defect in structure and use, and urgently needs to be further improved

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and the general products do not have a suitable structure to solve the above-mentioned problems. This is obviously related. The problem that the industry is eager to solve
