Description

anesthesia mask

technical field

The invention belongs to the field of medical devices, in particular to an anesthesia mask.

Background technique

An 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 anesthesia breathing circuit is connected to the anesthesia breathing circuit through the standard joint on the body of the anesthesia mask, and the anesthesia breathing circuit is connected to the anesthesia breathing machine or oxygen supply equipment, and the cushion for the gas is covered with the patient's mouth and nose, and the connection forms a passage to Fresh oxygen gas is delivered into the patient's airways. Although the performance of the existing anesthesia masks is relatively stable, there are still some problems during use, which are mainly manifested in the following aspects: 1. Due to the irregular and different facial shapes of patients, especially for the elderly, the masks cannot It has a better airtight effect, and it is prone to air leakage, which will affect the anesthesia effect; 2. When the patient needs concentrated oxygen supply, the oxygen cannot be sent to the patient's nostrils at the first time, causing the patient's treatment to be dangerous; 3. When an air leak occurs, the concentration of anesthetic gas in the mask body cannot be accurately controlled, resulting in unsatisfactory anesthesia effects, mild anesthesia, and medical accidents.

Contents of the invention

The present invention intends to provide an anesthesia mask to solve the problem that when the anesthesia mask in the prior art does not match the patient's facial contour, it is prone to air leakage and cannot send all the oxygen or anesthetic gas into the patient's nostrils at the first time.

A kind of anesthesia mask in this scheme comprises a cover body, one end of the cover body is connected with an interface, the other end of the cover body is connected with an air bag, and the joint between the air bag and the cover body is provided with a one-way air outlet valve; the cover body is provided with Hollow nasal plug, the nasal plug is connected to the elastic trachea, the end of the trachea away from the nasal plug extends to the interface, the nasal plug is rotatably connected with a connecting rod, the end of the connecting rod far away from the nasal plug is rotatably connected with a rotating block, and the end of the rotating block away from the connecting rod is fixedly connected with 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 with a ratchet, the ratchet is connected with a pawl, and the ratchet and the pawl are located on the outer surface of the cover; the interface is provided with an elastic and airtight An air bag, the air pipe passes through the air bag, and the outer wall of the cover body is provided with a plug for sealing the air bag.

The working principle and beneficial effect of this scheme: when in use, cover the patient's mouth and nose with an anesthesia mask, connect with the anesthesia breathing circuit or oxygen machine through the joint on the anesthesia mask body, and connect the anesthesia breathing circuit or oxygen machine with the anesthesia breathing machine or The oxygen supply equipment is connected to cover the gas-filled cushion with the patient's mouth and nose, and the connection forms a passage to deliver fresh oxygen gas to the patient's respiratory tract. During delivery, 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 member, and then closing the blocking member. At this time, the air enters the patient's nasal cavity directly through the trachea. In addition, according to needs, 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 go up and down, thereby realizing the control of the length of the trachea to meet the needs of different groups of people.

The anesthesia mask in this solution introduces mechanisms such as the trachea, plugs, and ratchets, so that the gas can enter the body directly through the nasal cavity, avoiding air leakage caused by the mismatch between the mask and the patient's face, and the patient being unable to fully inhale the required gas. problem, which in turn is conducive to the normal progress of patient treatment.

Furthermore, a tooth plug for separating the upper and lower teeth is also provided in the cover. By setting the dental plug, it helps to keep the airway unobstructed and helps the normal progress of the treatment.

Further, the inner edge of the airbag is provided with grooves for collecting saliva. During the use of the anesthesia mask, the patient often suffers from involuntary saliva leakage due to the sleeping position or the effect of drugs. By setting the groove, the saliva that flows out can avoid direct contact with the patient's face, which is conducive to keeping the patient's face clean.

Further, a collection box communicating with the groove is provided on the outer wall of the airbag, and the collection box is located at the bottom of the airbag. By setting the collection box, the saliva accumulated in the groove can be discharged in time.

Further, the bottom of the collection box is provided with a sewage outlet. By setting the sewage outlet, the saliva in the collection box can be directly discharged, or the saliva in the collection box can be led out by using a pipe.
