Description

Technical Field

[0001] The utility model relates to the technical field of ventilator masks, in particular to a ventilator mask capable of inserting a gastric tube to prevent facial pressure damage. Background Art

[0002] A ventilator mask usually refers to an auxiliary treatment device that delivers oxygen or mixed gases into the patient's respiratory tract through a mask, increases the patient's oxygen intake and the gas pressure in the respiratory tract, and improves the patient's respiratory function. Existing medical ventilator masks usually consist of a mask, a connecting tube, a flow meter, and an oxygen or mixed gas delivery device. In the actual treatment process, facing some special situations, such as the patient needs to undergo a gastroscopy while breathing oxygen, or cannot actively eat and needs to use a gastric tube to assist the patient in eating, etc., the existing fully enclosed ventilator mask is obviously not applicable. Therefore, it is very necessary to develop a ventilator mask with strong adaptability.

[0003] The authorized patent with announcement number CN211096854U discloses "a ventilator mask through which a gastric tube can be passed, comprising: a ventilator mask, comprising at least one gastric tube connection port with an internal thread; a gastric tube, which can pass through the gastric tube connection port; a sealing joint, which is detachably fixed to the gastric tube connection port and can be sleeved on the gastric tube to fix the gastric tube in the gastric tube connection port; wherein the sealing joint comprises: a pipe joint, which is an externally threaded tube and has an axial through-notch, which can be inserted into the gastric tube connection port and threadedly cooperate with the gastric tube connection port; a sealing plug, which is arranged at one end of the pipe joint through a connecting rib and can block the pipe joint". After specific implementation, "the utility model designs and develops a ventilator mask through which a gastric tube can be passed. A gastric tube connection port is arranged on the mask, which is conducive to food drainage, and the gastric tube can be detachably connected through the sealing joint. There is no need to repeatedly insert and remove the gastric tube, which ensures the sealing effect and prevents the gastric tube from falling out of the ventilator mask."
