Description

Technical Field

[0001] The invention belongs to the technical field of medical auxiliary equipment, and in particular relates to a mask specially used for artificial respiration. Background Art

[0002] Artificial respiration is an emergency treatment method when spontaneous breathing stops. It can provide oxygen supply to the body's important organs to prevent them from being damaged due to lack of oxygen. There are two common artificial respiration methods, namely mouth-to-mouth respiration and mouth-to-nose respiration. Mouth-to-mouth respiration is the most commonly used method. The method is as follows: the patient lies on his back, the rescuer puts one hand on the patient's forehead, and pinches the patient's nostrils with the thumb and index finger, then takes a deep breath, opens his mouth to close the patient's mouth, and blows into the patient's mouth twice in a row until the chest rises, stops blowing, releases the mouth that is tightly pressed against the patient, and relaxes the hand pinching the nostrils, turns the face to the side, listens with the ears to see if there is airflow exhaled, and then takes a deep breath of fresh air to prepare for the second blow. When the patient has finished exhaling, start the next same blow.

[0003] The biggest drawback of mouth-to-mouth breathing is that it is unhygienic. If the patient also suffers from an infectious disease, it is very easy to cause the spread of the disease, so the rescuer often has a psychological barrier of being infected with the disease, which affects the rescue effect. Chinese patent document CN 210020757 U discloses an artificial respiration mask, which is provided with two elastic bands on the mask body, and a breathing mouth and a one-way valve are attached to the mask body by strong glue, and an air inlet pipe and an air outlet pipe are installed on the one-way valve. It has good sealing performance, the gas will not flow back, and direct contact between mouths is avoided. The disadvantage of this solution is that it is difficult for the breathing mouth to wrap around the patient's mouth, resulting in the exhalation of the patient's mouth. Leakage, that is, although it solves the problem of isolating the mouth from the mouth, affects the air tightness, which will affect the rescue effect. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a special mask for artificial respiration, which can improve the airtightness between the mask and the patient's mouth while avoiding direct contact between the mouths, and also enable the rescuer to observe the patient's chest rise and fall in the exhalation position and observe the airflow out of the patient's nose after the exhalation is completed.

[0005] In order to achieve the above object, the technical solution of the present invention is as follows:

[0006] A mask for artificial respiration comprises a mask body and a temporary connection portion for fixing the mask body to a human head, a gas conduction pipeline is arranged on the mask body, the gas conduction pipeline comprises an inner end located inside the mask body and an outer end located outside the mask body, a cheek covering portion is fixed to the side of the mask body, a proximal end of the cheek covering portion is connected to the side of the mask body, and an outer end of the gas conduction pipeline is located between the middle position of the mask body and the distal end of the cheek covering portion.

[0007] As an improvement, the cheek covering portion is square, and the width of the cheek covering portion is 1 / 3-1 / 2 of the width of the mask body.

[0008] As an improvement, the inner end of the gas conduction pipeline is located between the middle position of the mask body and the side edge of the mask body.

[0009] As a further improvement, the gas conduction pipeline is overall S-shaped, and the gas conduction pipeline is formed by a plurality of sections of hard circular tubes connected in series flexibly.

[0010] As a further improvement, the temporary connection portion is an elastic band for covering the head, and the inner end of the gas conduction pipeline is in a bell-mouth shape.

[0011] As an improvement, the temporary connection parts are ear straps located on both sides of the mask body, and the ear straps on the side where the cheek covering part is located are located on the outer surface of the cheek covering part.

[0012] As an improvement, the temporary connection parts are ear straps located on both sides of the mask body, and the ear straps on the side where the cheek covering part is located are fixed to the side of the cheek covering part.

[0013] As an improvement, the cheek covering portion has a three-layer structure, which includes a water-absorbing layer, a waterproof layer, and a water-absorbing layer from the outside to the inside.

[0014] As an improvement, the mask body has a three-layer structure, which includes a waterproof layer, a filter layer, and a water absorption layer from the outside to the inside.

[0015] The beneficial effects of the present invention are as follows: (1) the three prescribed actions of the rescuer in artificial respiration, namely, "blowing with the mouth, looking with the eyes, and listening with the ears", are completed in the same body position, so that the rescuer does not need to change body position frequently, thereby improving the rescue efficiency; (2) when the rescuer performs the three prescribed actions, his face is pressed against the patient's mouth, which can achieve sealing around the patient's mouth, and also helps to put the patient's head in a backward state, which is beneficial to keep the patient's airway unobstructed; (3) by means of a gas transmission pipeline, the exhaled air can be directly introduced into the deep of the patient's mouth, and the rescuer blows with his mouth closed and holding the end of the gas transmission pipeline, so the probability of exhaled air leakage is small, and there is no need to install a one-way valve, thereby reducing the production cost and difficulty; (4) during artificial respiration, the rescuer's mouth is staggered with the patient's mouth, which can reduce the rescuer's psychological burden. In case the patient vomits, the rescuer does not need to worry about the vomit affecting his mouth, thereby facilitating the rescuer to devote himself to the rescue work.

[0021] Example 1

[0022] like Figure 1As shown, a mask for artificial respiration includes a mask body 10 and a temporary connection part 20 for fixing the mask body 10 to the human head. The mask body 10 is rectangular, and a cheek covering part 40 is fixed to the side of the mask body 10, and the proximal end of the cheek covering part 40 is connected to the side of the mask body 10. The cheek covering part 40 is square, the height of the cheek covering part 40 is equal to the height of the mask body 10, and the width of the cheek covering part 40 is 1 / 2 of the width of the mask body 10. The temporary connection part 20 is an ear strap located on both sides of the mask body 10, and the ear strap on the side where the cheek covering part 40 is located is fixed to the side of the cheek covering part 40. The mask body 10 is a three-layer structure, which is a waterproof layer, a filter layer, and a water absorbing layer from the outside to the inside. The waterproof layer is a waterproof non-woven fabric, the filter layer is an activated carbon fiber cloth, and the water absorbing layer is a medical non-woven fabric. The cheek covering part 40 is a three-layer structure, which includes a water-absorbing layer, a waterproof layer, and a water-absorbing layer from the outside to the inside. The outermost water-absorbing layer is cotton cloth, the waterproof layer is waterproof non-woven fabric, and the innermost water-absorbing layer is medical non-woven fabric.

[0023] The mask body 10 is provided with a gas conduction pipeline 30, which includes an inner end 31 located inside the mask body 10 and an outer end 32 located outside the mask body 10. The gas conduction pipeline 30 is generally S-shaped, the inner end 31 of the gas conduction pipeline 30 is located between the middle position of the mask body 10 and the side of the mask body 10, the middle section of the gas conduction pipeline 30 is fixed to the inside of the mask body 10, and the outer end 32 of the gas conduction pipeline 30 is located between the middle position of the mask body 10 and the distal end of the cheek covering part 40. The gas conduction pipeline 30 is formed by a plurality of sections of hard circular tubes connected in series flexibly. The hard circular tube is made of hard plastic, and when the hard circular tube is compressed by the face of the rescuer, the air flow can still be unobstructed. The gas conduction pipeline 30 can also be formed by arranging a plurality of sections of hard circular tubes on the outer surface of a hose.

[0024] The usage status of the invention is shown in the figure below. Figure 2 As shown, when in use, the rescuer presses his face sideways toward the patient's mouth, and at the same time inserts the outer end 32 of the gas conduction pipeline 30 between the patient's teeth. The rescuer uses facial compression and pipeline conduction to exhale, which can reduce the leakage of exhaled air around the patient's mouth. In the above position, the rescuer's ears are just near the patient's nose, so the rescuer can observe the rise and fall of the patient's chest with his eyes and listen to the patient's nasal breathing with his ears without changing positions. At the same time, because the patient's mouth is pressed by the rescuer's face, the patient's head can also be tilted back, which is conducive to the smooth flow of the patient's airway.

[0025] Example 2

[0026] like Figure 3As shown, the difference between this embodiment and embodiment 1 is that the width of the cheek covering portion 40 is 1 / 3 of the width of the mask body 10. When in use, part of the mask body 10 can be used to compress the patient's mouth. The temporary connection portion 20 is an ear strap located on both sides of the mask body 10, and the ear strap on the side where the cheek covering portion 40 is located is located on the outer surface of the cheek covering portion 40. The inner end 31 and the outer end 32 of the gas conduction pipeline 30 are respectively located on both sides of the mask body 10.

[0027] Example 3

[0028] like Figure 4 As shown, the difference between this embodiment and embodiment 1 is that the temporary connection part 20 is an elastic band for covering the head. When in use, the elastic band is covered on the head of the rescuer. The inner end 31 of the gas conduction pipeline 30 is in a bell-shaped shape and is located in the middle of the mask body 10. The bell-shaped inner end 31 covers the mouth of the rescuer to reduce the leakage of exhaled air around the mouth of the rescuer.
