Description

Special mask for anesthesia

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to anaesthetic mask, anaesthetic mask somatic part skids when in particular to pressurization is ventilated.

Background

At present, a mask used in clinical anesthesia generally comprises a breathing circuit connector, a bell-shaped mask body, a facial air cushion, an air cushion inflation valve, four head straps and hooks and the like. When the mask is used for ventilation, the method of buckling the mask is divided into a single technique and a two-hand technique, namely the single technique is that an operator buckles the mask on the oronasal face of a patient, a thumb and an index finger are naturally opened, two fingers are respectively held at the nasal end and the lower jaw end of the mask body, a tiger mouth is held at the shoulder of the mask body, and the rest four fingers support the mandibular branch and the mandibular angle of the patient, support the lower jaw and seal and ventilate. The two methods are that the operator buckles the mask on the nose, mouth and face of the patient, and the thumbs and thenar of the two hands hold the shoulders on the two sides of the mask body or the gas potential connecting part of the mask body and the mask. The rest four fingers of the two hands support the lower jaw support and the angle of the lower jaw of the patient and support the lower jaw, and the patient is ventilated in a sealed way. When an obese patient encounters a large face or a large airway resistance, and is also a difficult airway person, pressurized ventilation is required. When the mask is ventilated by a single-hand method, the situation that the pressure applied to one side of the mask is larger, the pressure applied to the other side of the mask is smaller, the stress on the two sides of the mask is uneven, and the air cushion of the mask is poorly sealed with the mouth, nose and face to cause air leakage often occurs. If the mask is buckled by a two-hand method, because the outer wall of the shoulder part of the bell-shaped mask body is smooth, the thumb and the thenar of the two hands have no force points and are easy to slip, when the pressure applied to the mask is large, the force extruding towards the center of the mask is generated, and the mask is deformed and cannot be tightly attached to the mouth, nose and face parts to cause air leakage. Moreover, the time for holding the mask by two hands is long, the muscle fatigue of the hands of the doctor is slightly long, and the air leakage is more easily caused when the holding force is reduced.

The technical problem to be solved by the utility model is to solve the problem that the existing bell-shaped mask body is smooth and has no stress point. Ear-shaped convex clasps for holding the thumb and thenar of both hands are arranged on the shoulders at both sides of the bell-shaped mask body.

SUMMERY OF THE UTILITY MODEL

The utility model adopts the technical proposal that:

a special anesthetic mask comprising: a breathing circuit connector, a bell-shaped mask body, a mask air cushion, an air cushion inflation valve and four head hooks; the shoulder part of the bell-shaped mask body is provided with an ear-shaped convex buckle, and one side of the ear-shaped convex buckle, which is close to the mask air cushion, is bent downwards along with the cambered surface of the bell-shaped mask body;

the lug-shaped raised handle holding surface on the shoulder part of the bell-shaped mask body is provided with anti-skid grains or even small granular dots.

Optionally, the bell-shaped mask body shoulder ear-protruding attacker contact surface has a shape that conforms to the thumb and thenar anatomy of the two hands.

The anaesthetic mask consists of a breathing circuit connector, a bell-shaped mask body, a facial air cushion, an air cushion inflation valve, four head belts, a hook and the like. The special mask for anesthesia is based on an original bell-shaped mask, the shoulder parts on the two sides of the bell-shaped mask body are provided with lug-shaped convex buckles for holding the thumb and the thenar of two hands, when an operator holds the lug-shaped convex buckles to apply pressure to the mask by the hands, the applied pressure is uniform and is conducted to the whole mask air cushion through the bell-shaped mask body, the mask is not easy to deform, the mouth, nose and face of a patient are uniformly stressed, the bell-shaped mask is tightly attached to the mouth, nose and face of the patient, the sealing performance is improved, and air leakage is prevented.

The ear-shaped convex buckle hand contact surface is designed into a shape which is matched with the thumbs of the two hands and the thenar anatomical structure, is convenient to hold and is not easy to deform due to even stress.

On the lug-shaped convex buckle hand holding surface on the shoulder part of the bell-shaped mask body, anti-skid textures or even small granular dots are designed, so that the frictional resistance between the hand part and the lug-shaped convex buckle hand is increased.

reference numerals: a breathing circuit connecting port 1, a bell-shaped mask body 2, a mask air cushion 3, an air cushion inflation valve 4, a four-head hook 5 and an ear-shaped convex buckle 6.

Detailed Description

The invention is further described below by way of an example of embodiment with reference to the accompanying drawings.

The utility model discloses special face guard of anesthesia, include: a breathing circuit connecting port 1, a bell-shaped mask body 2, a mask air cushion 3, an air cushion inflation valve 4 and four head hooks 5; the shoulder part of the bell-shaped mask body 2 is provided with an ear-shaped convex buckle 6, and one side of the ear-shaped convex buckle 6, which is close to the mask air cushion 3, is bent downwards along with the cambered surface of the bell-shaped mask body 2; the gripping surface of the lug-shaped convex handle 6 on the shoulder part of the bell-shaped mask body 2 is designed with anti-skid grains or even small granular dots. The contact surface of the lug-shaped raised handle 6 on the shoulder of the bell-shaped mask body 2 has a shape which is matched with the thumb and the thenar anatomical structure of the two hands. When the example is implemented, the breathing circuit of the anesthesia machine is connected with the breathing circuit connector 1 of the anesthesia mask of the utility model. After anesthesia induction, the mask is used for ventilation and oxygen supply operation, an anaesthetist presses the ear-shaped convex buckle 6 on the shoulder of the bell-shaped mask body 2 by using the thumbs and the thenar of the two hands, the mandible and the mandible angle of a patient are supported by the four fingers of the two hands, the ear-shaped convex buckle 6 is downwards pressed by the thumbs and the thenar of the two hands, centripetal grip force is formed by the thumb and the thenar of the two hands and the four fingers of the two hands, pressure is applied to the bell-shaped mask body 2 and is transmitted to the mask air cushion 3, the pressure of the mask air cushion 3 is uniformly applied to the oronasal face of the patient, and the mask air cushion 3 is tightly attached to the oronasal face of the patient, so that the.
