Description

Technical Field

[0001] This invention relates to the field of medical auxiliary technology, specifically to a rapid-response humidified oxygen inhalation device. Background Technology

[0002] Oxygen therapy is one of the most common emergency and treatment methods in hospitals, playing an irreplaceable role in clinical applications. During oxygen inhalation, to avoid irritating the patient's nasal cavity or causing dryness and discomfort, a humidifier is usually used to increase the humidity of the oxygen, thereby ensuring patient comfort and treatment effectiveness.

[0003] Currently, the most common humidification method in hospitals is to humidify oxygen with purified water. This method is the simplest and, while it can increase oxygen humidity to some extent and reduce irritation to the patient's respiratory tract, medical conditions are often limited in special scenarios such as emergency rescues. For example, at the scene of an emergency or during transport, medical staff usually have to rely on portable oxygen bags or cylinders to provide oxygen to patients. Although these devices can meet the patient's oxygen needs in emergencies, the lack of a corresponding humidification device may expose the patient to the risk of nasal dryness or even damage to the respiratory mucosa.

[0004] Existing oxygen humidification devices, such as the ventilator and humidifier for the ventilator disclosed in patent number 201510119616.5, primarily use heating to promote water evaporation, generating more water vapor per unit time. This water vapor is then mixed with oxygen to increase its humidity. While this method provides better humidification, heating the water takes time to produce sufficient water vapor, especially in low-temperature environments like winter. Therefore, this humidification method has a slow response time and cannot be quickly activated in emergency situations. Summary of the Invention

[0005] The present invention aims to provide a fast-response humidification oxygen absorption device to solve the problem of slow response time and inability to start up quickly in existing humidification devices.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rapid-response humidification oxygen inhalation device, comprising a humidification unit, the humidification unit including a liquid storage bottle, a venturi tube, and an air inlet pipe, the air inlet pipe being connected to the air inlet end of the venturi tube, and the liquid storage bottle being connected to the throat of the venturi tube; further comprising a buffer unit and a main body, the main body having a buffer cavity, the buffer unit being located within the buffer cavity, the buffer unit including a first baffle and a second baffle, a passage gap being formed between the first baffle and the second baffle, the first baffle and the second baffle dividing the buffer cavity into an air inlet cavity and an air outlet cavity, the air inlet cavity being located on the side of the second baffle away from the first baffle, the air outlet end of the venturi tube being connected to the air inlet cavity; the air outlet cavity being located on the side of the first baffle away from the second baffle, the air outlet cavity also being connected to an air outlet pipe.

[0007] The beneficial effects of this plan are:

[0008] 1. In emergency situations, oxygen is stored in oxygen cylinders. To increase the oxygen storage capacity, the pressure inside the cylinders is typically 12-15 MPa, and for some high-pressure oxygen cylinders, the pressure can even reach 20 MPa. When using the humidified oxygen delivery device in this solution, the inlet pipe is connected to the oxygen cylinder. The valve on the oxygen cylinder controls the amount of oxygen entering the inlet pipe per unit time, thereby controlling the oxygen supply to the breathing mask.

[0009] When oxygen enters the venturi tube, it creates a negative pressure at the throat of the venturi tube, thereby drawing in water from the storage bottle and mixing it with the oxygen to fully humidify the oxygen. In this process, there is no need to heat the water, so the device in this solution can respond quickly and is suitable for rapid use.

[0010] 2. In this solution, the amount of liquid that can be inhaled into the larynx can be increased by increasing the pressure difference between the two ends of the venturi tube, thereby increasing the amount of water mist in the oxygen. Therefore, the reservoir in this solution can also be filled with nebulized medication. In this case, the device can be used as a nebulizer. When a patient has an emergency such as acute laryngitis and needs medication to be delivered to the larynx quickly, doctors can save the patient's life in the ambulance.

[0011] 3. In this design, the first and second baffles are located inside the buffer chamber and can come into contact with the oxygen mixed with water mist that enters the buffer chamber. This allows the larger water mist particles in the oxygen to adhere to the first and second baffles, thereby reducing the humidity of the oxygen and making the oxygen humidity more suitable during oxygen inhalation.

[0012] Furthermore, the first baffle includes a first upper plate and a first lower plate. The first upper plate is hinged to the top of the buffer cavity, and the first lower plate is hinged to the first upper plate. The included angle between the first upper plate and the first lower plate is an obtuse angle.

[0013] Furthermore, the second baffle includes a second upper plate and a second lower plate, the second lower plate is hinged to the second upper plate, and the included angle between the second upper plate and the second lower plate is an obtuse angle; the second upper plate is connected to a buffer member, the upper end of which is connected to the top of the first upper plate or the buffer cavity.

[0014] The beneficial effects of this solution are as follows: The first and second baffles in this solution increase the contact area with oxygen, thereby promoting the precipitation of larger water mist particles and providing attachment space for water mist. At the same time, since the device in this solution is used in emergency rescue, the device is located inside the ambulance. During the ambulance's movement, the device is under vibration. At this time, the design of the first and second baffles in this solution can amplify the shaking of the first and second baffles, thereby causing the droplets attached to the first and second baffles to drip downwards for collection.

[0015] Furthermore, the buffer is a spring.

[0016] The beneficial effect of this solution is that the spring can further aggravate the vibration of the second baffle.

[0017] Furthermore, a torsion spring is provided between the first upper plate and the first lower plate.

[0018] The beneficial effects of this solution are as follows: the design of the torsion spring allows the lower end of the first lower plate to remain close to the second lower plate under its own weight and the action of the torsion spring, thereby promoting the contact between the first lower plate and the second lower plate and improving the contact effect between oxygen and the first lower plate.

[0019] Furthermore, the buffer chamber is connected to a drain pipe.

[0020] The beneficial effect of this solution is that when a certain amount of liquid water is stored in the buffer chamber, the liquid water is discharged from the drain pipe in a timely manner.

[0021] Furthermore, a flexible sealing sheet is provided between the first upper plate and the first lower plate. The upper and lower ends of the flexible sealing sheet are fixed to the first upper plate and the first lower plate, respectively, and are used to seal the gap between the first upper plate and the first lower plate.

[0022] The beneficial effects of this solution are: the flexible sealing sheet can prevent oxygen from escaping from the gap between the first upper plate and the first lower plate, promote the contact between oxygen and the first and second lower plates, and is more conducive to removing larger droplets of oxygen.

[0023] Furthermore, the lower end of the second lower plate is lower than the lower end of the first lower plate, and the lower end of the first lower plate abuts against the second lower plate.

[0024] The beneficial effects of this design are: the bottom of the first lower plate is higher, providing space for oxygen to flow into the exhaust chamber.

[0025] Furthermore, a piston is slidably sealed inside the buffer chamber, the upper end of the first upper plate is hinged to the piston, and the drain pipe is connected to the air outlet chamber; a torsion spring is also provided between the second upper plate and the second lower plate, and the connection part between the second upper plate and the second lower plate is opposite to the first upper plate; the bottom of the second lower plate is lower than the bottom of the first lower plate, and the bottom of the second lower plate abuts against the bottom of the buffer chamber.

[0026] The beneficial effects of this design are as follows: The second lower plate, under the action of the torsion spring, abuts against the bottom of the buffer chamber. When the first lower plate is suspended, it maintains an obtuse angle with the first upper plate under the action of gravity and the torsion spring. When the piston slides downwards, it increases the air pressure in the inlet and outlet chambers. At this time, opening the drain pipe allows for the rapid discharge of water accumulated in the inlet chamber. Simultaneously, because the air pressure in the outlet chamber is also high, oxygen can continuously flow out, thus maintaining oxygen supply to the patient.

[0027] Secondly, since the lower end of the second lower plate abuts against the bottom of the buffer chamber, when the liquid is discharged, the liquid in the intake chamber remains in the intake chamber. Therefore, after the piston resets, the remaining liquid can cover the bottom of the buffer chamber again, forming a liquid seal between the lower end of the second lower plate and the bottom of the buffer chamber. Thus, after the oxygen mixed with water mist enters the intake chamber, it passes between the first and second baffles and enters the exhaust chamber. During this process, the water mist comes into contact with the first and second baffles, thereby removing large-diameter droplets. Attached Figure Description

[0036] Example 1

[0037] Example 1 is basically as follows Figure 1 , Figure 2 and Figure 3 As shown, a fast-response humidification oxygen inhalation device includes a main body 1, a humidification unit and a buffer unit. The humidification unit includes a liquid storage bottle, a venturi tube and an air inlet pipe. The air inlet pipe is connected to the air inlet end of the venturi tube. The lower part of the liquid storage bottle is connected to the throat of the venturi tube. In this embodiment, the liquid storage bottle is provided with a liquid filling port, and a cap is threadedly connected to the liquid filling port for sealing the liquid filling port.

[0038] A piston 2 is installed inside the main body 1. The piston 2 is horizontal and slides and seals with the main body 1. A buffer chamber is formed below the piston 2. A buffer unit is located below the piston 2 and divides the buffer chamber into an outlet chamber on the left and an inlet chamber on the right. An outlet pipe 22 is installed on the left side of the piston 2. The outlet pipe 22 passes vertically through the piston 2 and is snapped and fixed to the piston 2 for exporting oxygen. The outlet end of the venturi tube is connected to a gas pipe 11. The gas pipe 11 passes through the right side wall of the main body 1 and is connected to the inlet chamber. In this embodiment, the buffer chamber is also connected to a drain pipe 12, and the drain pipe 12 is equipped with a valve for discharging the liquid that has settled in the buffer chamber.

[0039] The buffer unit includes a first baffle 3 and a second baffle 4, with a passage gap between them. The first baffle 3 includes a first upper plate 31 and a first lower plate 32. The first upper plate 31 is hinged to the bottom of the piston 2, and the top of the first lower plate 32 is hinged to the bottom of the first upper plate 31. The second baffle 4 includes a second upper plate 41 and a second lower plate 42, with the top of the second lower plate 42 hinged to the bottom of the second upper plate 41. In this embodiment, the front and rear ends of the first upper plate 31, the first lower plate 32, the second upper plate 41, and the second lower plate 42 are all slidably sealed to the sidewalls of the buffer cavity, and the bottom of the second lower plate 42 is lower than the bottom of the first lower plate 32. Two buffer members are provided between the second upper plate 41 and the first upper plate 31. In this embodiment, the buffer members are all springs 5, with both ends of the springs 5 ​​abutting against the first upper plate 31 and the second upper plate 41, respectively. In this embodiment, a telescopic rod is provided between the first upper plate 31 and the second upper plate 41. The two ends of the telescopic rod are respectively hinged to the first upper plate 31 and the second upper plate 41. The spring 5 is sleeved on the telescopic rod, and the telescopic rod guides the spring 5.

[0040] A first torsion spring is provided between the first upper plate 31 and the first lower plate 32, and a second torsion spring is provided between the second upper plate 41 and the second lower plate 42. The lower end of the second lower plate 42 is tilted to the right and is kept in contact with the bottom of the buffer cavity under the action of the second torsion spring. The lower end of the first lower plate 32 is tilted to the right under the action of gravity and the first torsion spring. In actual implementation, the lower end of the first lower plate 32 can also be made to be in contact with the left wall of the second lower plate 42, so that the included angle between the first upper plate 31 and the first lower plate 32 and the included angle between the second upper plate 41 and the second lower plate 42 are both obtuse angles.

[0041] A flexible sealing sheet is provided between the first upper plate 31 and the first lower plate 32. In this embodiment, the flexible sealing sheet is a thin film. The upper and lower ends of the flexible sealing sheet are respectively glued and fixed to the first upper plate 31 and the first lower plate 32, and are used to seal the gap between the first upper plate 31 and the first lower plate 32.

[0042] The specific implementation process is as follows:

[0043] When administering oxygen, first connect the outlet tube 22 to the oxygen mask. Then, place purified water or saline solution into the reservoir. Next, connect the inlet tube to the oxygen cylinder and gradually open the valve of the oxygen cylinder. When oxygen enters the throat of the venturi tube, a negative pressure is created, drawing in the water from the reservoir and mixing it with the oxygen to produce humidified oxygen. This humidified oxygen then enters the inlet chamber and flows through the gap between the first baffle 3 and the second baffle 4 into the outlet chamber. At this point, larger droplets of oxygen adhere to the first baffle 3 and the second baffle 4. The oxygen in the outlet chamber then enters the oxygen mask through the outlet tube 22, providing an oxygen environment for the patient. When the buffer chamber contains a large amount of water, opening the drain tube 12 and simultaneously sliding the piston 2 downwards will quickly drain the water.

[0044] When rapid nebulization is needed, the nebulized medication is added to the reservoir, creating a mixture of oxygen, medication, and water mist. The patient inhales oxygen while simultaneously inhaling the medication into the throat, making it suitable for use as a nebulizer in cases of acute laryngitis requiring rapid throat medication. For larger doses, piston 2 can be slid upwards, moving the second lower plate 42 above the bottom of the buffer chamber. This allows the oxygen mixed with water mist to bypass the passage gap and directly enter the oxygen mask through the outlet tube 22.

[0045] Example 2

[0046] Based on Example 1, such as Figure 4 and Figure 5As shown, in this embodiment, the drain pipe 12 is connected to the air outlet chamber, the buffer unit is located on the right side of the piston 2, the connection part of the second upper plate 41 and the second lower plate 42 is opposite to the first upper plate 31, and when the second lower plate 42 abuts against the bottom of the buffer chamber, when the piston 2 slides down, the connection part of the second lower plate 42 and the second upper plate 41 can abut against the first upper plate 31, so that the second upper plate 41 can push the first upper plate 31 to rotate clockwise.

[0047] In this embodiment, when the device is in use, the piston 2 slides downward, causing the second upper plate 41 and the second lower plate 42 to rotate relative to each other. At this time, the force provided by the second torsion spring increases, increasing the force between the second lower plate 42 and the buffer chamber. Thus, when the liquid is discharged, the liquid in the air intake chamber will not be discharged. During the upward reset of the piston 2, the force between the second lower plate 42 and the buffer chamber decreases, and the liquid in the air intake chamber is evenly distributed at the bottom of the buffer chamber, forming a liquid seal between the second lower plate 42 and the bottom of the buffer chamber. In actual implementation, the end of the drain pipe 12 away from the main body 1 can also be connected to the storage bottle to recover and reuse the clear water settled in the buffer chamber. Especially during atomization, recovering and reusing the agent can extend the atomization time and ensure the atomization effect.

[0048] Example 3

[0049] Based on Example 2, such as Figure 6 As shown, in this embodiment, elastic bands 6 are provided between the lower end of the second lower plate 42 and the bottom side wall of the air intake cavity, as well as between the second lower plate 42 and the first lower plate 32. One elastic band 6 is fixed at both ends to the lower end of the second lower plate 42 and the bottom of the air intake cavity, respectively; the other elastic band 6 is fixed at both ends to the lower end of the second lower plate 42 and the lower end of the first lower plate 32, respectively.

[0050] Specifically, both the bottom of the second lower plate 42 and the air intake cavity are provided with fixing holes. One elastic band 6 has both ends passing through the fixing holes and then secured with adhesive, thus connecting the second lower plate 42 to the bottom of the air intake cavity. After the second lower plate 42 slides upward, the elastic band 6 guides its repositioning, ensuring that after repositioning downward, the second lower plate 42 remains tilted to the right at its lower end and abuts against the bottom of the buffer cavity. The other elastic band 6 is fixed to the bottom of the first lower plate 32 and the second lower plate 42 respectively with adhesive. Thus, after the piston 2 repositions downward, when the lower end of the second lower plate 42 tilts to the right, the elastic band 6 pulls the lower end of the first lower plate 32 to the right, ensuring that the first upper plate 31 and the first lower plate 32 remain in a "<" shape.
