Abstract
The utility model discloses a first-aid respiration mask, which belongs to an artificial respiration device for saving acute disease patients. The purpose of the utility model is to solve the problems that gastric contents easily flow back to the respiratory system to cause danger and infection usually during artificial respiration, that operation needs professional techniques, etc. The utility model has the advantages of convenient operation, convenient operation and a safe first-aid respiration mask, wherein, the mask is composed of parts such as a catheter, an anesthetic mask, an inflation bag, an inflation tube, etc. When the artificial respiration is carried out, the catheter is inserted in the oral cavity of the patient, and the inflation bag can block the esophagus to prevent the gastric contents from flowing back. Safety is ensured.
Description
A kind ofly when respiratory arrest, be used for the first aid breathing mask that the artificial respiration rescues the emergency case patient, belong to medical use artificial respiration apparatus.
When the respiratory arrest due to all kinds of wounds, disease need practice artificial respiration, general now face shield venting method or the endotracheal intubation venting method of adopting.The shortcoming of face shield method is because portion gas is pressed into gastric, makes the increased pressure of gastric, causes gastric content to backflow and is inhaled into trachea, causes the obstruction and the infection of trachea, bronchus and lung.Trachea interpolation rule needs special equipment and operation professional technique, and these are unapproachable under emergency and general curative condition.
The purpose of this utility model is in order to overcome above-mentioned shortcoming, can to avoid backflowing of gastric content, need not operate professional technique again, proposing the first aid breathing mask of a kind of energy safety operation.
Technical characterictic of the present utility model is as follows: this first aid breathing mask is formed by anaesthetic mask and catheter combination, conduit (1) passes anaesthetic mask (5), seal on conduit (1) top that anaesthetic mask (5) is inboard, connecting a gas cell (3) near catheter tip, in logical gas cell (3) cavity of gas tube (2) one terminations, the other end stretches out anaesthetic mask (5) is convenient to inflation, has several passages (4) on conduit (1).
The shape of cross section of conduit (1) can be circular, also can be oval-shaped, and circular pipe is convenient to make, elliptical catheter is more suitable for the physiological characteristics in the people, identical in conduit cross section, under the same traffic conditions of air, elliptical catheter can make the opening width in oral cavity littler.
The position of opening several passages (4) on the conduit (1) is more than gas cell (3) in 7～10 centimeters scopes, in the time of in conduit inserts the oral cavity esophagus, just in time between front tooth and epiglottis, the gross area sum in several holes is equal to or greater than the cross-sectional area of conduit to passage.Be convenient to the circulation of air like this.Conduit can be made with rubber or silicone rubber, and is both soft, is difficult for again flattening.
The shape of gas cell (3) and position can be positioned at the top globulate of conduit (1), also can be around the outside around the conduit rear circlewise.Gas cell (3), gas tube (2) can be made with latex or silicone rubber, softness and high resilience, and stimulate less to human body.
When rescuing when practicing artificial respiration to the emergency case patient of respiratory arrest, the conduit (1) of first aid breathing mask is inserted patient's mouth, anaesthetic mask (5) covers patient on the face, because human physilogical characteristic, conduit (1) enters esophagus smoothly, anaesthetic mask (5) is with mouth, nose sealing, inflate to gas cell (3) by gas tube (2), the gas cell of inner inflatable (3) covers esophagus, the gas of being sent into by conduit (1) enters trachea one bronchus one lung through passage (4), carry out gas exchange, can carry out artificial ventilation like this and breathe.
The conduit and the air bag of first aid breathing mask have stimulation to esophagus, and under waking state, patient can not tolerate.For abirritate, can coat anesthetis at catheter surface, as 1% tetracaine, 3～4% lignocaine.In most of the cases, the patient to be in comatose state be adaptable.Whether this stimulation can be used for monitoring patient clear-headed, as long as after patient regained consciousness, swallowing reflex was recovered, autonomous respiration also just recovers, and just can remove face shield.
The utility model has the advantages that simple in structurely, easy to operate, when practicing artificial respiration,, can not cause that gastric content backflows and cause into respiratory system and to infect and dangerous, safe and reliable because gassiness gas cell (3) can cover esophagus.
Description of drawings:
Fig. 1 is the structural representation of first aid breathing mask.Wherein (1) is conduit, and (2) are gas tubes, and (3) are gas cells, and (4) are passages, and (5) are anaesthetic masks.
Fig. 2 is the sketch map when with the first aid breathing mask patient being practiced artificial respiration.Wherein A is a tongue body, and B is an epiglottis, and C is an air flue, and D is an esophagus.
Embodiment, a first aid breathing mask as shown in Figure 1, its conduit (1) they are to make with medical F34 tracheal intubation, there are 6 side openings the both sides, lower end, 4 millimeters of the diameters in hole; Anaesthetic mask (2) is medical large size anaesthetic mask, conduit passes anaesthetic mask, pass place's adhering and sealing, ring-type gas cell (3) is enclosed within conduit (1) end, gas tube (2) and gas cell (3) are communicated with, in conduit (1), stretch out face shield from the other end beyond, be convenient in gas cell (3), inflate by gas tube (2).This kind first aid breathing mask can be used for rescuing the emergency case patient that grows up.
Claims (4)
1, a kind ofly when respiratory arrest, is used for the first aid breathing mask that the artificial respiration rescues the emergency case patient, mainly form by anaesthetic mask and catheter combination, it is characterized in that conduit (1) passes anaesthetic mask (5), seal on conduit (1) top that anaesthetic mask (5) is inboard, connecting a gas cell (3) near catheter tip, in logical gas cell (3) cavity of gas tube (2) one terminations, the other end stretches out anaesthetic mask (5) is convenient to inflation, has several passages (4) on conduit (1).
2, according to the described first aid breathing mask of claim 1, the shape of cross section that it is characterized in that conduit (1) can be circular, also can be oval-shaped.
3, according to the described first aid breathing mask of claim 1, in 7～10 centimeters scopes, the gross area sum in several holes is equal to or greater than the cross-sectional area of conduit more than gas cell (3) in the position that it is characterized in that opening on the conduit (1) several passages (4).
4, according to the described first aid breathing mask of claim 1, it is characterized in that the shape of gas cell (3) and the top globulate that the position can be positioned at conduit (1), also can center on around conduit (1) rear outside circlewise.
