Description

Technical Field

[0001] The present invention relates to the field of medical assistance technology, and in particular to a fast-response humidification oxygen inhalation device. Background Art

[0002] Oxygen inhalation is one of the most common emergency and treatment methods in hospitals, playing an irreplaceable and important role in clinical applications. During oxygen inhalation, to prevent nasal irritation or dryness, a humidifier is often used to increase the humidity of the oxygen, thereby ensuring patient comfort and therapeutic efficacy.

[0003] Currently, the most common humidification method used in hospitals is to humidify oxygen with purified water. This method is the simplest and, while it can increase the humidity of oxygen to a certain extent and reduce irritation to the patient's respiratory tract, it is often limited in special scenarios such as emergency rescue. For example, at the emergency scene or during transport, medical staff are usually forced to rely on portable oxygen bags or oxygen cylinders to supply oxygen to patients. While these devices can meet patients' oxygen needs in emergency situations, the lack of supporting humidification devices may put patients at risk of nasal dryness and even respiratory mucosal damage.

[0004] Existing oxygen humidification devices, such as those disclosed in Patent No. 201510119616.5, which describes a ventilator and humidifier for a ventilator, use heating to promote water evaporation, generating more water vapor per unit time. This water vapor is then mixed with oxygen to increase the humidity of the oxygen. While this method provides better humidification, it takes time to heat the water to generate sufficient water vapor, especially in winter, when the ambient temperature is lower. Therefore, this humidification method is slow to respond 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 that the existing humidification device has a slow response time and cannot start quickly.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a fast-response humidification oxygen inhalation device, comprising a humidifying unit, the humidifying unit comprising 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, and the liquid storage bottle is connected to the throat of the venturi tube; it also comprises a buffer unit and a main body, a buffer cavity is provided in the main body, the buffer unit is located in the buffer cavity, the buffer unit comprises a first baffle and a second baffle, a through gap is formed between the first baffle and the second baffle, the first baffle and the second baffle divide the buffer cavity into an air inlet cavity and an air outlet cavity, the air inlet cavity is located on the side of the second baffle away from the first baffle, the air outlet end of the venturi tube is connected to the air inlet cavity; the air outlet cavity is located on the side of the first baffle away from the second baffle, and the air outlet cavity is also connected to the air outlet pipe.

[0007] The beneficial effects of this program are: 1. During first aid and other procedures, oxygen is stored in oxygen cylinders. To maximize oxygen storage capacity, the pressure of the oxygen inside the cylinders is typically between 12 and 15 MPa. For some high-pressure cylinders, the pressure can even reach 20 MPa. With the humidified oxygen inhalation device described in this solution, an intake pipe is connected to the oxygen cylinder. A valve on the cylinder controls the amount of oxygen entering the pipe per unit time, thereby controlling the amount of oxygen delivered to the breathing mask.

[0008] When oxygen enters the venturi tube, negative pressure is formed at the throat of the venturi tube, thereby sucking in the water in the liquid storage bottle and mixing it with the oxygen to fully humidify the oxygen. There is no need to heat the water in this process, so the device of this scheme can respond quickly and is suitable for quick use.

[0009] 2. In this solution, the amount of liquid that can be inhaled by the throat can be increased by increasing the pressure difference at both ends of the Venturi tube, thereby increasing the amount of water mist in the oxygen. Therefore, the liquid storage bottle in this solution can also be added with a nebulizer for atomization treatment. At this time, the device of this solution can be used as a nebulizer. When the patient suffers from an urgent disease such as acute laryngitis and needs to quickly deliver the medicine to the throat, the doctor can race against time to rescue the patient in the ambulance.

[0010] 3. The first baffle and the second baffle in this solution are located in the buffer chamber and can come into contact with the oxygen mixed with water mist entering the buffer chamber, so that the water mist with larger particle size in the oxygen adheres to the first baffle and the second baffle, thereby reducing the humidity of the oxygen, making the oxygen humidity more suitable when oxygen inhalation is performed.

[0011] 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 chamber, the first lower plate is hinged to the first upper plate, and the angle between the first upper plate and the first lower plate is an obtuse angle.

[0012] Furthermore, the second baffle includes a second upper plate body and a second lower plate body, the second lower plate body is hinged to the second upper plate body, and the angle between the second upper plate body and the second lower plate body is an obtuse angle; the second upper plate body is connected to a buffer member, and the upper end of the buffer member is connected to the top of the first upper plate body or the buffer cavity.

[0013] The beneficial effects of this solution are as follows: the first baffle and the second baffle in this solution increase the contact area with oxygen, thereby promoting the precipitation of water mist with larger particle size and providing attachment space for the attachment of water mist. At the same time, since the device in this solution is used during first aid, the device is located in the ambulance. During the driving of the ambulance, the device is in a vibration process. At this time, the design of the first baffle and the second baffle in this solution can intensify the shaking of the first baffle and the second baffle, thereby promoting the droplets attached to the first baffle and the second baffle to drip downward for collection.

[0014] Furthermore, the buffer member is a spring.

[0015] The beneficial effect of this solution is that the spring can further intensify the vibration of the second baffle.

[0016] Furthermore, a torsion spring is provided between the first upper plate and the first lower plate.

[0017] The beneficial effect of this solution is that the design of the torsion spring enables the first lower plate to maintain its lower end close to the first lower plate under the action of its own gravity and the torsion spring, thereby causing the first lower plate to offset the second lower plate and improving the contact effect between oxygen and the first lower plate.

[0018] Furthermore, the buffer chamber is connected to a drain pipe.

[0019] The beneficial effect of this solution is that when a certain amount of liquid water is stored in the buffer cavity, the liquid water is discharged from the drain pipe in a timely manner.

[0020] 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 respectively fixed to the first upper plate and the first lower plate, and are used to seal the gap between the first upper plate and the first lower plate.

[0021] The beneficial effect of this solution is that the flexible sealing sheet can prevent oxygen from being discharged from the gap between the first upper plate and the first lower plate, promote the contact between oxygen and the first lower plate and the second lower plate, and is more conducive to removing larger droplets in the oxygen.

[0022] Furthermore, the lower end of the second lower plate body is lower than the lower end of the first lower plate body, and the lower end of the first lower plate body abuts against the second lower plate body.

[0023] The beneficial effect of this solution is that the bottom of the first lower plate is higher, which provides space for oxygen to flow into the gas outlet cavity.

[0024] Furthermore, a piston is slidingly sealed in the buffer chamber, the upper end of the first upper plate is hinged to the piston, and the discharge 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 is against the bottom of the buffer chamber.

[0025] The beneficial effects of this solution are as follows: the second lower plate in this solution, 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 due to gravity and the torsion spring. When the piston slides downward, the air pressure in the inlet and outlet chambers increases. Opening the drain pipe at this time quickly drains water accumulated in the inlet chamber. Simultaneously, because the air pressure in the outlet chamber is simultaneously high, oxygen in the outlet chamber can continue to flow out, maintaining oxygen supply to the patient.

[0026] Secondly, since the lower end of the second lower plate body is against the bottom of the buffer chamber, when the liquid is discharged, the liquid in the air inlet chamber still remains in the air inlet chamber. Therefore, after the piston is reset, the remaining liquid can re-cover the bottom of the buffer chamber, and a liquid seal is formed between the lower end of the second lower plate body and the bottom of the buffer chamber. As a result, after the oxygen mixed with water mist enters the air inlet chamber, it passes between the first baffle and the second baffle and enters the air outlet chamber. In this process, the water mist is prompted to contact the first baffle and the second baffle, thereby removing large-sized droplets. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Example 1 Example 1 is basically as Figure 1 、 Figure 2 and Figure 3 As shown, a fast-response humidification oxygen inhalation device includes a main body 1, a humidifying unit and a buffer unit. The humidifying unit includes a liquid storage bottle, a venturi tube and an air inlet pipe 11. The air inlet pipe 11 is connected to the air inlet end of the venturi tube, and the lower part of the liquid storage bottle is connected to the throat of the venturi tube. The liquid storage bottle in this embodiment is provided with a liquid filling port, and the liquid filling port is threadedly connected to a cover body for sealing the liquid filling port.

[0030] A piston 2 is provided in 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 provided below the piston 2 and divides the buffer chamber into an air outlet chamber on the left and an air inlet chamber on the right. An air outlet pipe 22 is installed on the left side of the piston 2. The air outlet pipe 22 vertically passes through the piston 2 and is fixed to the piston 2 for discharging oxygen. The air outlet end of the venturi tube is connected to an air pipe 11, which passes through the right side wall of the main body 1 and is connected to the air inlet chamber. The buffer chamber in this embodiment is also connected to a drain pipe 12, and a valve is provided on the drain pipe 12 for discharging liquid settled in the buffer chamber.

[0031] The buffer unit includes a first baffle 3 and a second baffle 4, with a clearance formed 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. The top of the second lower plate 42 is 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 against the sidewalls of the buffer chamber, 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 both springs 5, with the ends of the spring 5 respectively abutting against the first upper plate 31 and the second upper plate 41. 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 hinged to the first upper plate 31 and the second upper plate 41 respectively. The spring 5 is sleeved on the telescopic rod and guided by the telescopic rod.

[0032] 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 maintained in a state of being against the bottom of the buffer chamber under the action of the second torsion spring. Under the action of gravity and the first torsion spring, the lower end of the first lower plate 32 is tilted to the right. In actual implementation, the lower end of the first lower plate 32 can also be made to stick to the left wall of the second lower plate 42, so that the angle between the first upper plate 31 and the first lower plate 32 and the angle between the second upper plate 41 and the second lower plate 42 are both obtuse angles.

[0033] A flexible sealing sheet is provided between the first upper plate 31 and the first lower plate 32. The flexible sealing sheet in this embodiment is made of a 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.

[0034] The specific implementation process is as follows: When inhaling oxygen, first connect the outlet pipe 22 to the oxygen mask, then put pure water or physiological saline into the liquid storage bottle, then connect the inlet pipe 11 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 formed in the throat, which sucks the water in the liquid storage bottle and mixes with the oxygen to obtain humidified oxygen. After the humidified oxygen enters the air inlet cavity, it enters the air outlet cavity through the gap between the first baffle 3 and the second baffle 4. At this time, the larger particle size droplets in the oxygen adhere to the first baffle 3 and the second baffle 4. The oxygen in the air outlet cavity enters the oxygen mask through the outlet pipe 22, providing an oxygen environment for the patient. When there is a lot of water stored in the buffer chamber, open the drain pipe 12 and slide the piston 2 downward at the same time to quickly drain the water.

[0035] When rapid atomization therapy is required, the atomized medication is added to the liquid storage bottle, and a mixed gas of oxygen, medication, and water mist is formed. The patient can inhale the oxygen while also inhaling the medication into the throat. This allows the device to be used as a nebulizer for rapid treatment in cases such as acute laryngitis where rapid throat medication is required. When a large dose of medication is required, the piston 2 can also be slid upward, and the second lower plate 42 can be slid above the bottom of the buffer chamber, so that the oxygen mixed with the water mist enters the oxygen mask directly through the outlet pipe 22 without passing through the gap.

[0036] Example 2 On the basis of Example 1, Figure 4 and Figure 5As shown, the discharge pipe 12 in this embodiment is connected to the air outlet cavity, the buffer unit is located on the right side of the piston 2, and the connection part between the second upper plate 41 and the second lower plate 42 is opposite to the first upper plate 31. When the second lower plate 42 is against the bottom of the buffer cavity, when the piston 2 slides downward, the connection part between the second lower plate 42 and the second upper plate 41 can be against the first upper plate 31, so that the second upper plate 41 can push the first upper plate 31 to rotate clockwise.

[0037] When the device of this embodiment is in use, the downward sliding of the piston 2 causes the second upper plate 41 and the second lower plate 42 to rotate relative to each other, thereby increasing the force provided by the second torsion spring, thereby increasing the force between the second lower plate 42 and the buffer chamber. As a result, when the liquid is discharged, the liquid in the air inlet chamber is not discharged. During the upward return of the piston 2, the force between the second lower plate 42 and the buffer chamber decreases, and the liquid in the air inlet chamber is evenly distributed at the bottom of the buffer chamber, thereby forming a liquid seal between the second lower plate 42 and the bottom of the buffer chamber. In actual implementation, the end of the discharge pipe 12 away from the main body 1 can also be connected to the liquid storage bottle to recycle the clear water settled in the buffer chamber for reuse. In particular, when atomizing, recycling the medicine can extend the atomization time and ensure the atomization effect.

[0038] Example 3 On the basis of Example 2, 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 inlet cavity, and between the second lower plate 42 and the first lower plate 32. The two ends of one elastic band 6 are respectively fixed to the lower end of the second lower plate 42 and the bottom of the air inlet cavity; the two ends of the other elastic band 6 are respectively fixed to the lower end of the second lower plate 42 and the lower end of the first lower plate 32.

[0039] Specifically, the second lower plate 42 and the bottom of the air inlet chamber are each provided with a fixing hole. The two ends of one elastic band 6 are inserted through the fixing hole, fitted over it, and then secured with adhesive, thereby connecting the second lower plate 42 to the bottom of the air inlet chamber. After the second lower plate 42 slides upward, the elastic band 6 guides the second lower plate 42 back to its original position, ensuring that after the second lower plate 42 is reset downward, its lower end remains tilted rightward and abuts against the bottom of the buffer chamber. The two ends of the other elastic band 6 are respectively secured to the bottoms of the first lower plate 32 and the second lower plate 42 by adhesive. Therefore, after the piston 2 is reset downward, when the lower end of the second lower plate 42 tilts rightward, the elastic band 6 drives the lower end of the first lower plate 32 rightward, thereby maintaining the "<" shape between the first upper plate 31 and the first lower plate 32.

It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
