Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an airway heating humidifier. Background Art

[0002] An artificial airway is a gas channel established by inserting a tube into the trachea through the mouth, nose, or tracheotomy to ensure the patient's airway is unobstructed. It is an effective connection established between the airway, air, and other gas sources. Establishing and using an artificial airway is an important way to rescue critically ill patients. The main purpose of establishing an artificial airway is to facilitate the use of mechanical ventilation or pressurized oxygen; to keep the airway unobstructed and facilitate the removal of airway secretions or foreign matter; to effectively prevent the accidental aspiration of vomitus and oral and nasal secretions into the lungs for patients who are unconscious, especially those in coma; to increase the effective ventilation of the alveoli, reduce airway resistance, and improve the efficiency of respiratory gas exchange; and to facilitate atomization humidification and intra-airway drug delivery.

[0003] However, for patients who have an artificial airway established through a tracheotomy, many have lost their ability to protect their airway (e.g., prolonged unconsciousness, inability to effectively cough up sputum, upper airway obstruction, etc.). When these patients are weaned from the ventilator but temporarily unable to remove the tracheostomy tube, airway humidification becomes particularly important. Because the tracheotomy is directly open, when inhaling cold, dry air, the airway easily becomes dry, and sputum becomes viscous and difficult to expel, ultimately increasing the chance of lung infection and delaying hospitalization. Therefore, a heated airway humidifier has been proposed to address the above problems. Summary of the Invention

[0004] In response to the problems in the prior art, the present invention provides an airway heating humidifier that realizes automatic oxygen and water supply, ensures full contact between oxygen and water, heats evenly and is highly safe, and has a good humidification effect.

The spring telescopic rods are arranged through the multiple arc grooves. The spring-type telescopic rod automatically expands and contracts, causing the first and second hollow rotating rods to rotate during expansion and contraction, thereby changing the orientation of the first and second water spray holes, as well as the height of the third and fourth water spray holes, further enhancing oxygen humidification and heating. The heating tube is disposed within the hollow tube, and water in the humidification tank flows through the hollow tube, thereby fully heating the water in the humidification tank.

Ring 91, multiple arc grooves 92 equidistantly distributed in an annular manner on the fixed ring, multiple spring telescopic rods 93 equidistantly distributed in an annular manner and fixed at one end on the hollow tube, a roller 94 rotatably arranged at the other end of the spring telescopic rod, a first hollow rotating rod 95 rotatably arranged at one end of the spring telescopic rod, a second hollow rotating rod 96 rotatably arranged at the other end of the spring telescopic rod and rotatably arranged at the other end of the first hollow rotating rod, a first connecting hose 97 with both ends inserted into the hollow tube and the first hollow rotating rod respectively, and a second connecting hose 97 with both ends inserted into the second hollow rotating rod respectively. A second connecting hose 98 is provided in a hollow rotating rod and a second hollow rotating rod; a plurality of first water spray holes 99 are provided on the first hollow rotating rod at equal intervals and facing downward; a plurality of second water spray holes 910 are provided on the second hollow rotating rod at equal intervals and facing downward; a plurality of third water spray holes 911 are provided on both sides of the first hollow rotating rod at equal intervals; and a plurality of fourth water spray holes 912 are provided on both sides of the second hollow rotating rod at equal intervals; the liquid absorbing plate 8 is provided with a plurality of fourth through holes 81, the apertures of the plurality of fourth through holes being gradually increased from the inside of the liquid absorbing plate to the outside;First, cover the patient's mouth and nose with the breathing mask, and inject water into the humidification tank through the water injection device. When the water volume reaches the requirement, the water injection will stop automatically, and water will be automatically injected when the water volume is low. Turn the temperature control switch to heat the heating tube to control the temperature of the heating tube, that is, to control the temperature of the water in the humidification tank. Start the water pump to generate suction at the lower end of the hollow tube to suck the water in the humidification tank into the hollow tube. The water in the hollow tube enters the first hollow rotating rod through the first connecting hose, and the first hollow rotating rod and the second hollow rotating rod are connected through the second connecting hose, so that the water in the hollow tube enters the first hollow rotating rod and the second hollow rotating rod respectively, and finally flows from the first water spray hole to the fourth water spray hole. The water sprayed out of the spray hole falls back into the humidifier tank. The above arrangement forms a circulation system for the water in the humidifier tank. The water in the humidifier tank circulates from top to bottom, and the gas injection device injects gas into the gas distribution plate, causing oxygen to be sprayed out from the gas distribution plate. Finally, the oxygen moves upward from the bottom of the humidifier tank, in the opposite direction of the water circulation, thereby accelerating the contact between oxygen and water. The oxygen is humidified again by the spray device, making the humidification of oxygen more comprehensive. The humidified and heated oxygen enters the oxygen mask through the exhaust pipe and is inhaled by the patient. The temperature control switch has a protection mechanism. If the temperature is too high, it will automatically disconnect, that is, the heating tube stops heating, improving the safety of the heating process.

[0026] Specifically, the air equalizing plate 2 includes a circular plate 21 fixedly mounted on the hollow tube, a cavity 22 provided in the circular plate, a plurality of first through holes 23 provided at the upper end of the circular plate, and a plurality of second through holes 24 corresponding to the plurality of first through holes and provided at the lower end of the circular plate; the plurality of first through holes are gradually enlarged from the inside to the outside of the circular plate, and the apertures of the first through holes and the second through holes are the same; the gas injection device injects oxygen into the cavity of the circular plate, and the oxygen in the cavity is eventually ejected from the plurality of first through holes. The circular plate is fixedly mounted on the hollow tube, so that the circular plate rotates during the rotation of the hollow tube, so that the ejected oxygen is more comprehensive, and the water in the humidification tank flows through the first through holes and the second through holes, so that the oxygen and water convect, and the flow rate of the water increases when passing through the first through holes and the second through holes, so that the oxygen is fully in contact with the water.

[0027] Specifically, the gas injection device 3 includes a joint 31 connected to the cavity and rotatably arranged on the circular plate, an air inlet pipe 32 fixed on the humidification tank and with one end inserted into the joint, a base 33 fixed in the air inlet pipe, a third through hole 34 provided on the base, a movable plate 35 located above the base and movably arranged in the air inlet pipe, a first spring 36 with two ends respectively fixed on the movable plate and the base, a pull rod 37 with one end fixed on the movable plate, a sealing plate 38 fixed on the other end of the pull rod, a plurality of guide rods 39 equidistantly distributed in an annular manner and with one end fixed on the top of the humidification tank, and a plurality of guide rods 39 movably provided on the guide rod. The conical plate 310 on the guide rod, the second spring 311 which is sleeved on the guide rod and fixed at both ends on the conical plate and the humidifying tank, the through groove 312 provided on the humidifying tank, the slide 313 which is perpendicular to the through groove and provided on the humidifying tank, the slide 314 which is movable in the slide groove, the L-shaped push rod 315 which is fixed on the slide and one end of which is fixed on the conical plate, the push rod 316 which is fixed on the other end of the L-shaped push rod, and the fifth through hole 317 provided on the movable plate; oxygen enters the bottom of the movable plate through the fifth through hole and pushes the sealing plate to move through the third through hole, so that oxygen enters from the third through hole. The air enters the air inlet pipe, and the oxygen in the air inlet pipe enters the air equalizing plate. That is, the above arrangement enables the oxygen to enter the air equalizing plate through the third through hole. When the pressure in the humidifier tank is too high, that is, when the patient exhales, the first spring is used to reset the movable plate, so that the movable plate drives the pull rod to move together, so that the sealing plate re-seals the third through hole, playing a good one-way valve role. At the same time, the conical plate moves on the guide rod, so that the second spring is compressed, and the movement of the conical plate drives the L-shaped push rod to move, so that the push rod moves, so that the push rod pushes the sealing plate to move, so that the sealing plate seals the third through hole, and the oxygen stops The air in the air intake duct is rotated in a direction of the air intake pipe, and the air inlet is rotated in a direction of the air intake duct to form an L-shaped groove, which is used to draw the air into the humidifier.

[0028] Specifically, the water injection device 4 includes a first limiting ring 41 fixed in the humidification tank and a second limiting ring 42 located above it, a counterweight plate 43 located between the first limiting ring and the second limiting ring, limiting rods 44 distributed equidistantly in an annular shape and fixed at one end on the counterweight plate, a floating plate 45 located between the second limiting ring and the counterweight plate and movably arranged on the limiting rod, a third spring 46 sleeved on the limiting rod and fixed at both ends on the floating plate and the counterweight plate, a plurality of conical holes 47 provided on the counterweight plate, and a plurality of conical holes corresponding to the plurality of conical holes and provided on the floating plate. A plurality of conical diversion columns 48, a plurality of diversion holes 49 equidistantly distributed around the conical diversion columns and provided on the floating plate, a water inlet pipe 410 fixed at one end and passing through the second limiting ring, a sealing ring groove 411 corresponding to the water inlet pipe and provided on the floating plate, and a first one-way valve provided in the water inlet pipe; water enters the humidification tank from the water inlet pipe, and when the water drives the floating plate to rise, so that the sealing ring groove on the floating plate coincides with the water inlet pipe, that is, when the water inlet pipe is inserted into the sealing ring groove, water stops entering the humidification tank, the floating plate rises, and the height of the floating plate is controlled by the second limiting ring. The height of the water is controlled by controlling the height of the counterweight plate through the second limit plate. When the floating plate rises, the third spring is set to pull the counterweight plate up together, so that the lower end of the counterweight plate is separated from the first limit ring. When oxygen passes through the conical hole, the conical hole setting plays a role in gathering oxygen, and then the gathered oxygen is diverted through the conical diversion column. Finally, the oxygen is diverted from multiple diversion holes into multiple small bubbles, which are set through the counterweight plate to exert a certain pulling force on the floating plate. However, the buoyancy of the floating plate is greater than the gravity of the counterweight plate, so that the floating plate floats more stably through the counterweight plate setting, avoiding The up and down movement of the floating plate causes unstable water injection, so that the amount of water in the humidification tank is constant; the floating plate rises through the third spring setting, so that the limit rod moves up together, so that the upper end of the limit rod abuts against the second limit ring, thereby controlling the gap between the floating plate and the counterweight plate, controlling the gap between the conical diversion column and the conical hole, and controlling the water flow rate and the oxygen discharge rate; when the water and oxygen collide at this place, the counterweight plate is set to make the counterweight plate move slightly up and down, and the floating plate remains stationary to adapt to the pressure change in the humidification tank; the first one-way valve is set to prevent water in the water inlet pipe from flowing back.

[0029] Specifically, the exhaust pipe 5 has two ends made of hard material and a middle made of soft material, and is provided with a second one-way valve 51 therein. The oxygen mask 6 is connected to the exhaust pipe 5 and is provided with a third one-way valve 61. The third one-way valve is close to the patient's nose. The oxygen mask is also provided with an elastic bandage 62. The elastic bandage is used to bind the patient's head so that the oxygen mask can cover the patient's mouth and nose and fix the oxygen mask. When the patient inhales, the oxygen in the humidifier enters the exhaust pipe, and the oxygen in the exhaust pipe enters the oxygen mask. At this time, the second one-way valve is opened and the third one-way valve is closed. When the oxygen in the oxygen mask is inhaled by the patient, the pressure in the humidifier tank decreases, the conical plate drops, and the third through hole opens, allowing the oxygen to enter the gas equalizing plate through the air inlet pipe; when the patient blows air, the pressure in the humidifier tank increases with the inflow of oxygen, causing the conical plate to rise, and finally the sealing plate to seal the third through hole, stopping the input of oxygen. At this time, the second one-way valve is closed, that is, the oxygen in the humidifier tank stops entering the oxygen mask, and the third one-way valve is opened, allowing the patient's exhaled gas to be discharged from the third one-way valve. The third one-way valve is close to the patient's nose, so that the patient's exhaled gas can quickly discharge from the oxygen mask.

[0030] Specifically, the driving device 15 includes a rotating shaft 151 rotatably sleeved on the fixed tube and with the lower end fixed on the hollow tube, a first gear 152 fixedly sleeved on the rotating shaft, a second gear 153 meshing with the first gear, and a reduction motor 154 fixed on the fixed frame and used to drive the second gear to rotate; the reduction motor drives the second gear to rotate, so that the first gear rotates, thereby rotating the rotating shaft, and the rotating shaft is fixed on the hollow tube, thereby rotating the hollow tube. The hollow tube is rotated by the above-mentioned drive, and the fixed tube does not rotate, that is, the water pump does not rotate. The wires on the water pump pass through the fixed tube and are connected to the external power supply to power the water pump; the reduction motor is purchased on the market.
