Description

Double-bag butterfly wing tide type nose-mouth combined skirt edge double-joint mask

Technical Field

The utility model relates to the field of medical auxiliary equipment, in particular to a double-sac butterfly wing tide type nose-mouth combined skirt edge double-joint mask.

Background

Along with the global development of 2019 new coronaries pneumonia, the Omik virus is spread in China, the epidemic situation of Shanghai is still severe, and meanwhile, serious illness, critical illness and death cases of Shanghai are increased gradually, so that the country pays more attention to pulmonary diseases, and in the development process of various pulmonary diseases, such as: in the acute exacerbation stage, the severe stage and the severe-to-return stage, more efficient oxygen ventilation, in particular non-invasive ventilation, assisted ventilation, mechanical ventilation and the like are often required.

The air of the general mask reaches the trachea from lips to oral cavity, to pharynx and to throat, and finally to throat, so that the lung generates respiratory function, the passing cavity is composed of soft tissues, respiratory obstruction is easy to occur, and the tongue body has large movement, so that the tongue is a common cause of tongue drop.

The nose vestibule can be pressed by the general mask, the nose vestibule can be pressed by the patient when the mask is moved, so that the nostril is narrowed and even blocked, the ventilation of the nasal cavity is not smooth or lost, meanwhile, the pressure of the mask is pressed from outside the nose vestibule to inside, the nose vestibule is pressed, the nostril is narrowed, and various shaping, filling and the like of the nose are added, so that the shape of the nose vestibule is changed, tissues are softened, the supporting force of the nose vestibule is greatly reduced, and the deformation of the nose vestibule is further aggravated.

The ordinary face mask has difficult oxygen supply to noninvasive ventilation, auxiliary ventilation and mechanical ventilation, the tightness of the ordinary face mask is poor, the air leakage probability is high, meanwhile, the ordinary face mask is difficult to operate, the operation difficulty is gradually increased, the breathing is easier to control, the stress response of a patient is stronger, if the strong stress response of the patient is to be restrained, the physiological balance of the patient is often disturbed, and the longer the time is, the more serious the operation difficulty is.

And when the conventional common mask achieves noninvasive mechanical ventilation, auxiliary ventilation and mechanical ventilation, the operation difficulty is high, the problems of displacement, air leakage, falling and the like are easy to occur between maintenance, and the correction difficulty is high and complex due to the high operation difficulty, and meanwhile, the damage to patients is also increased.

The mask ventilation is also an important circle in the emergency treatment process, and is more important due to the characteristics of short time in emergency treatment, complex condition, critical illness state, simple operation, quick use, high effectiveness and the like.

The first aid is complicated, and female nurses and women's arms, palms, fingers and other muscle forces are smaller than those of men, and the operation difficulty of the EC method is high, so that the ventilation of the mask is difficult to achieve for general medical staff.

In modern clinical medicine, a respirator is used as an effective means capable of replacing autonomous ventilation by manpower, is widely used for respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support treatment and emergency resuscitation, and occupies a very important position in the field of modern medicine. The breathing machine is a vital medical device which can prevent and treat respiratory failure, reduce complications, save and prolong the life of patients.

The breathing machine controls and assists the breathing of a patient, and when the patient breathes noninvasively, the breathing machine can be matched with a breathing mask to be used, in order to ensure the supply amount of oxygen, the current common mask is used for covering the whole mouth and the nose or is used for supplying oxygen through a single nasal catheter, the nasal mask supplies oxygen and the like, but when the patient supplies oxygen through positive pressure, the pressure of the throat is reduced after the gas flows out of the oral cavity of the patient, so that the gas does not enter the air pipe to supply the internal breathing of the lung at higher pressure.

If the breathing machine is required to achieve sufficient air supply, the pressure needs to be increased, but after the pressure is increased, the mask possibly generates air leakage due to the overlarge pressure, at the moment, the mask needs to be firmly fixed on the face of a patient, the pressure needs to be increased, the mask presses the tissues under the mask more seriously, the ischemia is more serious, and the nose bridge and the forehead of the patient are all bones under the extrusion of the mask for a long time, so that the buffering is smaller, the blood circulation is less, and necrosis, infection and the like caused by long-time ischemia are easy to occur.

Meanwhile, because the mouth and face conditions of different people are different, especially the old people cause facial depression due to factors such as tooth fall-off when using the air supply mask, the mask is generally pressed from the outside of the mask to the inside of the mask for oxygen supply, the cheek is increased to be depressed into the oral cavity, the probability of mask air leakage is increased, and therefore the problems of air leakage and the like can be caused.

The double-bag butterfly wing tidal type nose-mouth combined skirt edge double-joint mask comprises a mask body 1, an oxygen inlet mechanism and a tidal type sealing mechanism;

the oxygen inlet mechanism and the tidal type closing mechanism are arranged outside the mask body 1;

the oxygen inlet mechanism comprises a first connecting pipe 2 communicated with the lower part of the outer surface of the mask body 1, a partition plate 3 is fixedly connected to the inner part of the first connecting pipe 2, the partition plate 3 divides the inner wall of the first connecting pipe 2 into an outer cavity 27 and an inner cavity 26, three communication holes 4 are formed in the surface of the partition plate 3 in a penetrating mode, two nasal tubes 5 which are respectively communicated with the two communication holes 4 and extend to the inner part of the mask body 1 are fixedly connected to the surface of the inner cavity 26 on one side of the partition plate 3, one-way valve 6 is arranged at the outer end of the other communication hole 4 and positioned on one side of the outer cavity 27, and a first ventilation pipe 7 is communicated with the other end of the first connecting pipe 2.

The other end of the first breather pipe 7 in the oxygen inlet mechanism is communicated with an air outlet pipe of a breathing machine, when a patient wears the mask, the tail ends of the two nasal pipes 5 are inserted into the two nostrils of the patient, when the breathing machine is used for supplying air, air enters the outer cavity 27 of the first connecting pipe 2 through the first breather pipe 7, then enters the two nasal pipes 5 through the two communicating holes 4 and finally enters the air passage of the patient, and when the breathing machine is used for supplying air intermittently, the patient exhales, and the exhaled air is discharged through the unidirectional valve 6 at the moment and cannot be accumulated in the mask, so that the smoothness of the breathing of the patient is ensured.

The middle part of the outer surface of the mask body 1 is communicated with a second connecting pipe 11, the outer end of the second connecting pipe 11 is communicated with a second vent pipe 12, and the other end of the first vent pipe 7 is communicated with the second vent pipe 12.

When the breathing machine is used for feeding gas, the gas directly enters the body of a patient through the two nasal tubes 5, but the nasal tubes 5 cannot control the breathing of the patient, and oxygen entering through the nasal tubes 5 can be discharged through the mouth of the patient, so the breathing machine is further communicated with the second connecting tube 11 on the mask body 1, the second connecting tube 11 is externally communicated with the second ventilation tube 12, the second ventilation tube 12 is communicated with the first ventilation tube 7, and the two ventilation tubes are used for feeding gas through the breathing machine, so that when the breathing machine is used for feeding gas, the oxygen can enter the body of the patient through the nasal tubes 5 and can fill the interior of the mask body 1, and thus the oxygen enters the body of the patient through the oral cavity of the patient, and the oxygen is prevented from being discharged from the mouth of the patient.

The outer surface of the first connection pipe 2 is fixedly connected with a connection pipe 10, and both ends of the connection pipe 10 are respectively communicated with the interiors of the inner cavity 26 and the outer cavity 27.

On a common single-hole mask, the communicating pipe 10 is arranged on the surface of the first connecting pipe 2, so that the inner cavity 26 and the outer cavity 27 are mutually communicated, when the breathing machine is used for feeding air, oxygen enters the patient through the nose pipe 5 and simultaneously enters the inner cavity 26 through the communicating pipe 10, and finally the interior of the mask body 1 is filled, and the function of preventing the oxygen from being discharged from the mouth of the patient can be realized.

When the nasal cavity is ventilated and the second connecting pipe 11 is closed, gas reaches the throat from the nasal cavity, then reaches the oral cavity from the mouth, finally reaches the mask body 1, and the pressure in the mask body 1 is minimum through the poiseuille law, so that the tightness of the mask is greatly improved and the difficulty of sealing the mask is reduced.

The unidirectional valve 6 can ensure the smooth breath of the patient.

The first vent pipe 7, the second vent pipe 12 and the communicating pipe 10 are all provided with a gas pipe clamp 8.

The air pipe clamp 8 can adjust the ventilation diameters of the first ventilation pipe 7, the second ventilation pipe 12 and the communication pipe 10, thereby adjusting the air supply amounts of the three.

The tidal type closing mechanism comprises an annular air bag 14 fixedly connected to the outer outline of the mask body 1, an air pipe 13 is communicated with the outer surface of the annular air bag 14, a connecting block 15 is fixedly connected to the top end of the mask body 1, a forehead air bag 16 is fixedly connected to the top end of the connecting block 15, a first through pipe 17 is communicated between the forehead air bag 16 and the annular air bag 14, a jaw air bag 18 is fixedly connected to the bottom end of the inside of the mask body 1, and the inside of the jaw air bag 18 is communicated with the inside of the annular air bag 14.

When the mask is used, besides a breathing machine for oxygen supply, one tidal breathing machine for oxygen supply is also used, the air pipes of the tidal breathing machine for oxygen supply are directly communicated with the air pipe 13 of the annular air bag 14, the air supply intervals of the two breathing machines are kept synchronous, when oxygen is supplied, the tidal breathing machine for oxygen supply is used for inflating the inside of the annular air bag 14, part of air filled into the annular air bag 14 enters the inside of the forehead air bag 16 through the first through pipe 17, part of air enters the inside of the jaw air bag 18 communicated with the inside of the annular air bag 14, at the moment, the annular air bag 14, the forehead air bag 16 and the jaw air bag 18 are simultaneously inflated, the outer surfaces of the air bags are tightly attached to the face of a patient, and when oxygen is supplied, even if the pressure of the mask body 1 is large, the phenomenon of air leakage cannot easily occur.

The tidal breathing machine for supplying air to the plurality of air bags can work before the oxygen supplying breathing machine, so that the plurality of air bags are firstly inflated to be tightly attached to the face, and oxygen supply is performed after sealing is realized.

The combined use method of the double respirators comprises the following steps: coordinated respiration of tidal ventilator and ventilator: tidal ventilators and oxygen ventilators are quite different, tidal breathing is mainly regulated to be in a pressure mode, pressure is mainly passed through a tidal air bag of a face mask, and the oxygen ventilators can be used in a capacity mode, a pressure mode or other modes according to the condition of a patient.

Before the oxygen supply breathing machine breathes the mask, the tidal breathing machine ventilates in advance for a period of time (0.05 seconds), the annular air bag 14 is filled in advance, the mask ventilates and the face is closed, when the oxygen supply breathing machine ventilates at positive pressure, the annular air bag 14 is filled, air leakage in the mask is reduced, and ventilation of a patient is guaranteed. Other masks may be used with this design.

However, when the tidal breathing machine is deflated, the mask is ensured not to leak air when the breathing machine is in the later period of ventilation when the breathing machine is in the end of breathing and the expiration is started, or 0.05 seconds later.

When the single breathing machine is used with the mask in a matched mode, a ventilation pipeline is communicated between the first ventilation pipe 7 and the annular air bag 14, and when the single breathing machine is used for supplying air, air can enter the annular air bag 14 through the ventilation pipeline communicated between the first ventilation pipe 7 of the annular air bag 14, so that the annular air bag 14 and a plurality of other air bags are supported to play a role in sealing, and the principle is the same as that of the double breathing machine.

When guaranteeing normal ventilation, reduced the pressure in oral cavity and face guard (because gas is from the nasal cavity, to the pharyngeal portion, to the oral cavity finally to the face guard in), reduced medical personnel especially woman nurse, doctor and general personnel carry out the degree of difficulty that the face guard ventilates, improve the success rate. Because the diameter of the nostril is much smaller than that of the lip, the air leakage amount is also much smaller, the nasal cavity is guaranteed to be airtight, and the ventilation amount of the lung of a patient can be better guaranteed.

When the air supply is intermittent, the air in the plurality of air bags flows back to the air supply pipeline of the breathing machine under the action of the pressure, the air pressure in the plurality of air bags is reduced after the air is discharged, the air bags are not inflated, the pressure applied to the face of a patient is reduced, and the face blood vessel is prevented from being pressed and damaged due to the fact that the patient wears the mask for a long time.

The annular air bag 14 is internally provided with an inner annular air bag 28 along its outline shape, and the inner annular air bag 28 is fixedly connected to the mask body 1.

The inner ring air bag 28 is positioned in the annular air bag 14, a gap is formed between the inner ring air bag 28 and the annular air bag 14, when the breathing machine supplies air, the gas can fill the gap to expand the annular air bag 14, when the air supply is intermittent, the gas in the annular air bag 14 flows back to the air supply pipeline under the action of pressure, the inner ring air bag 28 is closed, the gas in the inner ring air bag 28 can not circulate, so that the inner ring air bag can always keep a shape, the annular air bag 14 is prevented from shrinking too severely when the air supply is intermittent, the mask leaks too much, the inner ring air bag 28 can enable the face of the mask to be better closed, and the fitting is better.

The inner ring air bag 28 is a closed air bag, is smaller than the annular air bag 14, is matched with a one-way air injection valve, can inject air into the inner ring air bag 28, can be shaped in advance, can reduce the air consumption of the annular air bag 14, can be better closed with the mouth, nose and face, and is better in fit, so that the damage of the mask can be reduced.

In the process of auxiliary breathing and mechanical control breathing, a synchronous intermittent instruction ventilation mode (SIMV) is a main mode of transition to normal breathing, and can ensure oxygen supply of a patient and cultivate double functions of autonomous breathing of the patient, so that a skirt edge is designed on the lower edge of the annular air bag 14 to form a valve structure, gas in the mask can go out and cannot be inhaled from the outside, only the gas in the mask can be inhaled at the moment, and the inhaled gas quantity can be reacted on the breathing machine to finally finish SIMV.

The outer surfaces of the tail ends of the two nasal tubes 5 are provided with nasal tube air bags 24, and the inner surfaces of the tail ends of the two nasal tubes 5 are provided with a plurality of air supply holes 25 communicated with the interior of the nasal tube air bags 24.

In the process that the gas enters the inside of the human body through the nasal tube 5, when the gas enters the tail end of the nasal tube 5, the gas enters the inside of the nasal tube air bag 24 through a plurality of air supply holes 25, and at the moment, the nasal tube air bag 24 is inflated to seal the inside of the nasal cavity, so that the defect of insufficient air supply caused by air leakage is avoided. The tidal air bag is formed, on one hand, when positive pressure ventilation is carried out, the air bag is expanded to be clung to the inner wall of the vestibule of the nose, so that the air leakage of the nasal cavity is reduced, and on the other hand, when the positive pressure ventilation is lost, the air bag is recovered, the compression of the inner wall of the nasal cavity is relieved, and the blood supply of the nasal cavity is recovered.

The tidal action of the nasal cannula balloon 24 is to apply the positive pressure of the nasal cannula 5 rather than the pressure of the tidal machine supplying the annular balloon 14, and all tides may be done with positive ventilator pressure but cannot be used for coordinated inflation.

The nasal cavity is soft tissue except the nasal vestibule, and the rest is bone tissue, so that the nasal cavity has a good supporting effect, can reduce airway obstruction, and simultaneously, the tongue body increases the airway obstruction from the original flap effect, converts the airway obstruction into the pressure increasing effect on the upper airway of the larynx due to the change of the air flow direction, thereby being beneficial to the air reaching the trachea from the larynx. Meanwhile, the nasal catheter has the function of reducing airway pressure for the mask, positive pressure is arranged in the nasal cavity, the nasal catheter has the function of supporting the nasal vestibule, and the nasal catheter also has the function of supporting the nasal vestibule, in particular to a tidal air bag at the front end of the nasal catheter, so that the nasal catheter has the function of supporting, and can recover blood supply in the nasal cavity.

Because the nasal cannula 5 of the present utility model is for ventilation and is thicker than typical oxygen delivery nasal catheters, for patient comfort, the nasal cavity may be coated with a local anesthetic prior to placement into the nasal cavity, which may increase the flexibility of the nasal cannula 5 and nasal cannula balloon 24 within the nasal cavity, and may reduce irritation to the nasal vestibule.
