Description

Technical Field

[0001] The invention belongs to the field of medical devices, and in particular relates to an anesthesia mask. Background Art

[0002] The anesthesia mask is a medical device used to cover the patient's mouth and nose during anesthesia administration or oxygen delivery. It mainly includes an interface, a mask body, an air bag and a one-way valve. When in use, the standard connector on the anesthesia mask body is connected to the anesthesia breathing circuit, and the anesthesia breathing circuit is connected to the anesthesia breathing machine or oxygen supply equipment. The soft cushion that allows the gas to enter is covered with the patient's mouth and nose, and a passage is formed to deliver fresh oxygen gas to the patient's respiratory tract. Although the performance of the existing anesthesia mask is relatively stable, there are still some problems during use, which are mainly manifested in the following aspects: First, due to the irregular and different facial shapes of patients, especially for the elderly, the mask cannot play a good sealing effect, and it is easy to leak, thereby affecting the anesthesia effect; second, when the patient needs centralized oxygen supply, the oxygen cannot be fully delivered to the patient's nostrils in the first time, causing the patient's treatment to be dangerous; third, when leakage occurs, the concentration of anesthetic gas in the mask body cannot be accurately controlled, resulting in unsatisfactory anesthesia effect, and there will be a situation of lighter anesthesia, which is prone to medical accidents. Summary of the invention

[0003] The present invention is intended to provide an anesthesia mask to solve the problem that when the anesthesia mask in the prior art does not match the facial contour of the patient, air leakage easily occurs and oxygen or anesthetic gas cannot be fully delivered to the patient's nostrils in the first place.

[0004] An anesthesia mask in the present scheme includes a mask body, one end of the mask body is connected to an interface, the other end of the mask body is connected to an air bag, and a one-way air outlet valve is provided at the connection between the air bag and the mask body; a hollow nasal plug is provided in the mask body, the nasal plug is connected to an elastic trachea, the end of the trachea away from the nasal plug extends to the interface, a connecting rod is rotatably connected to the nasal plug, the end of the connecting rod away from the nasal plug is rotatably connected to a rotating block, the end of the rotating block away from the connecting rod is fixedly connected to a rotating shaft, the rotating shaft is perpendicular to the length direction of the rotating block, the end of the rotating shaft away from the rotating block is connected to a ratchet, the ratchet is connected to a pawl, and the ratchet and the pawl are both located on the outer surface of the mask body; an elastic and airtight air bag is provided in the interface, the trachea passes through the air bag, and a blocking piece for sealing the air bag is provided on the outer wall of the mask body.

[0005] The working principle and beneficial effects of this solution: When in use, the anesthesia mask covers the patient's mouth and nose, and is connected to the anesthesia breathing circuit or oxygen machine through the joint on the anesthesia mask body. The anesthesia breathing circuit or oxygen machine is connected to the anesthesia breathing machine or oxygen supply equipment, and the soft cushion that allows gas to pass covers the patient's mouth and nose, forming a passage to deliver fresh oxygen gas to the patient's respiratory tract. During the delivery process, when the patient's face does not match the anesthesia mask, the air bag can be inflated until it completely blocks the interface by opening the blocking piece, and then the blocking piece can be closed. At this time, the gas directly enters the patient's nasal cavity through the trachea. In addition, as needed, the ratchet can be rotated, the ratchet drives the rotating block, the rotating block drives the connecting rod, and the connecting rod drives the trachea to rise and fall, thereby achieving control of the trachea length to meet the needs of different groups of people.

[0006] The anesthesia mask in this solution introduces mechanisms such as a trachea, a plug and a ratchet, so that the gas can enter the body directly through the nasal cavity, avoiding the problem of air leakage caused by the mismatch between the mask and the patient's face and the patient's inability to fully inhale the required gas, which is beneficial to the normal progress of the patient's treatment.

[0007] Furthermore, a tooth plug for separating the upper and lower teeth is also provided in the mask body. The tooth plug is provided to help keep the respiratory tract unobstructed and help the normal treatment.

[0008] Furthermore, the inner edge of the airbag is provided with a groove for collecting saliva. When the anesthesia mask is used, the patient often drools unconsciously due to sleeping posture or drug effects. By providing the groove, the saliva is prevented from directly contacting the patient's face, which is conducive to keeping the patient's face clean.

[0009] Furthermore, a collecting box connected to the groove is provided on the outer wall of the airbag, and the collecting box is located at the bottom of the airbag. By providing the collecting box, the saliva collected in the groove can be discharged in time.

[0010] Furthermore, a sewage outlet is provided at the bottom of the collection box. By providing the sewage outlet, the saliva in the collection box can be directly discharged, or the saliva in the collection box can be led out using a pipe. BRIEF DESCRIPTION OF THE DRAWINGS
