Description

Technical Field

[0001] The present invention relates to the technical field of airway humidification and oxygen inhalation, and particularly relates to an airway humidification and oxygen inhalation device. Background Art

[0002] After tracheotomy in the intensive care unit, the loss of respiratory tract moisture increases and the movement of respiratory tract cilia weakens in patients with artificial airways. If the humidification is insufficient, it will lead to the formation of artificial airway sputum crusts, dyspnea, and an increase in pulmonary infections. Airway humidification is the key to ensuring the patency of the artificial airway, and is the core measure to maintain respiratory function and prevent complications. By simulating the temperature and humidity of the physiological environment, it ensures the patency of the airway, promotes the clearance of secretions, and ultimately reduces the risk of pulmonary infection.

[0003] Currently, the airway humidification methods include active heating and humidification methods and passive heating and humidification methods:

[0004] Active heating and humidification is to heat the humidifying liquid to the target temperature (usually set at 37°C) through an electric heating device, and convey the gas through the respiratory pipeline to ensure that the temperature and humidity of the gas entering the airway meet the physiological requirements. However, this method requires continuous electric heating and has the disadvantages of high energy consumption and high cost.

[0005] The passive heating and humidification method uses the heat and moisture of the patient's exhaled gas to passively heat and humidify the inhaled gas. For example, an artificial nose captures the heat and moisture in the patient's exhaled gas through a special material and releases it into the inhaled gas during the next inhalation to achieve recycling. However, the heating and humidification effect of the artificial nose highly depends on the temperature and humidity of the patient's exhaled gas and is not suitable for critically ill patients with weak breathing;

[0006] Another example is the prior art CN111658923A, an intelligent respiratory rehabilitation device that can assist in expectoration, pronunciation, and evaluation. It absorbs and stores the moisture in the exhaled gas through materials such as sponges, and during the subsequent inhalation process, the new air drives the moisture and heat on the water-absorbing component to re-enter the human lungs. However, in this prior art, the moisture in the exhaled gas has been stored in the sponge material, and long-term use will cause bacteria to breed on the sponge due to humidification residues, which is likely to endanger the health of patients.

[0007] Based on the above problems, the present invention provides an airway humidification and oxygen inhalation device that combines active and passive heating and humidification, has low energy consumption, and high safety. Summary of the Invention

[0016] Preferably, a plurality of partition plates are fixed to the inner wall of the outer shell and are distributed up and down, and the partition plates are fixed to the outer ends of the spiral tubes. The plurality of partition plates divide the space inside the outer shell into a plurality of flow chambers distributed up and down. The other end of the air outlet pipe is communicated with the lowermost flow chamber; openings are provided at the front ends of the partition plates of odd layers, and openings are provided at the rear ends of the partition plates of even layers. The plurality of flow chambers are communicated through the openings, which is convenient for the exhaled gas to fully exchange heat with the oxygen in the spiral tube.

[0017] Preferably, the passive heating and humidifying component further includes a water collecting component arranged at the top of the water chamber. The water collecting component includes a partition plate fixed to the top inside the outer box, and a water collecting member is fixed inside the partition plate.

[0018] Preferably, a through hole is provided on one side of the outer box close to the outer shell, and the partition plate is communicated with the uppermost flow chamber inside the outer shell through the through hole.

A waterproof and breathable film for blocking moisture is fixed inside the installation cylinder; the gas after heat exchange inside the outer shell enters the partition plate, the moisture in the gas is collected by the water collecting member, and then the gas is discharged through the exhaust pipe;

[0019] The waterproof and breathable film is a new type of polymer waterproof material with the functions of air permeability, waterproofness, and oil resistance. Its principle is as follows: there are many tiny holes on the waterproof and breathable film, and the aperture of the holes is usually below 10 microns. The diameter of gas molecules is smaller, and they can smoothly pass through these micropores for diffusion movement, thus realizing the air permeability function. The intermolecular distance of liquid water is smaller, and the surface tension is larger, so that liquid water cannot pass through these tiny holes and is blocked on one side of the film, achieving the waterproof effect.

Some have on-site displays, while some do not. Due to characteristics such as small size and stable performance, temperature and humidity sensors are widely used in various fields of production and life.

[0024] In the above technical solution, the technical effects and advantages provided by the present invention are as follows:

[0025] 1. By heating the sterilized distilled water in the water chamber with an electric heating tube to generate water vapor, the water vapor is carried into the patient's airway by oxygen to achieve active heating and humidification; the exhaled gas of the patient exchanges heat with the oxygen to heat the oxygen, and at the same time, the moisture in the gas is recovered into the water chamber, and the water vapor generated by reheating the moisture is carried into the patient's airway by oxygen to achieve passive heating and humidification.

[0046] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further introduced in detail below with reference to the accompanying drawings.

[0047] The present invention provides as Figures 1-9An airway humidifying oxygen inhalation device shown in the figure includes an oxygen inhalation mask 1. An oxygen inlet pipe group is provided at the air inlet of the oxygen inhalation mask 1. The oxygen inlet pipe group includes an inlet pipe 2, a delivery pipe 21, a connecting pipe 22, a spiral pipe 23, and an oxygen connection pipe 24 that are connected in sequence. One end of the inlet pipe 2 away from the delivery pipe 21 is connected to the air inlet of the oxygen inhalation mask 1, and a one-way valve that only allows oxygen in the inlet pipe 2 to enter the oxygen inhalation mask 1 is installed at the air inlet of the oxygen inhalation mask 1. The oxygen connection pipe 24 is connected to the oxygen pipe of an oxygen tank;

[0048] Moreover, an outlet pipe 5 is provided at the air outlet of the oxygen inhalation mask 1. One end of the outlet pipe 5 is connected to the air outlet of the oxygen inhalation mask 1, and a one-way valve that only allows the gas in the oxygen inhalation mask 1 to enter the outlet pipe 5 is installed at the air outlet of the oxygen inhalation mask 1;

[0049] After the patient wears the oxygen inhalation mask 1, the oxygen connection pipe 24 is connected to the oxygen pipe, and oxygen is transported into the oxygen inhalation mask 1 along the path of the spiral pipe 23, the connecting pipe 22, the delivery pipe 21, and the inlet pipe 2 to supply oxygen to the patient. The gas exhaled by the patient enters the outlet pipe 5, and a passive heating and humidifying component 4 is connected to the outlet pipe 5.

[0050] Then, an active heating and humidifying component 3 is provided on the oxygen inlet pipe group. Specifically, the active heating and humidifying component 3 includes an outer box 31. A water chamber 32 and a heating chamber 33 are arranged up and down in the outer box 31. A water inlet pipe 36 is fixed on one side of the outer box 31 away from the passive heating and humidifying component 4, and a drain pipe 37 is provided at the rear end of the outer box 31. Both the water inlet pipe 36 and the drain pipe 37 are communicated with the water chamber 32, and a sealing cover needs to be installed at the port of the water inlet pipe 36. Sterilized distilled water can be added into the outer box 31 through the water inlet pipe 36. A liquid level gauge 7 for monitoring the water level in the water chamber 32 is fixed at the top of the outer box 31, and a disinfection lamp 38 is also fixed at the top inside the water chamber 32 for disinfecting and sterilizing the water in the water chamber 32. After use, the remaining water in the water inlet pipe 36 can be discharged through the water inlet pipe 36.

[0051] An electric heating pipe 34 for heating the water in the water chamber 32 is fixed in the heating chamber 33. An air pipe 35 is fixed at the top of the outer box 31, and the air pipe 35 is communicated with the delivery pipe 21; the water in the water chamber 32 is heated by the electric heating pipe 34, and the water vapor enters the delivery pipe 21 through the air pipe 35. The oxygen in the delivery pipe 21 carries the water vapor and is transported to the oxygen inhalation mask 1 to realize active airway humidifying oxygen inhalation for the patient.

[0052] Then, as Figures 1-5 shown, the passive heating and humidifying component 4 is arranged on one side of the outer box 3 and extends into the outer box 31 for recovering the temperature and water in the exhaled gas of the patient to heat and humidify the oxygen. Specifically, the passive heating and humidifying component 4 includes a housing 41 fixed on one side of the outer box 31, and the spiral pipe 23 is arranged inside the housing 41;

[0053] A air treatment device is fixed to the bottom of the rear end of the outer shell 41. The other end of the air outlet pipe 5 is communicated with the inside of the outer shell 41 through the air treatment device. The gas exhaled by the patient enters the air outlet pipe 5, and then the gas is treated and enters the inside of the outer shell 41 to heat the oxygen in the spiral pipe 23. The spiral pipe 23 is made of materials with good thermal conductivity such as copper and aluminum.

[0054] Furthermore, a plurality of partition plates 42 distributed up and down are fixed to the inner wall of the outer shell 41, and the partition plates 42 are fixed to the outer ends of the spiral pipes 23. The plurality of partition plates 42 divide the space inside the outer shell 41 into a plurality of circulation cavities 43 distributed up and down. The other end of the air outlet pipe 5 is communicated with the lowermost circulation cavity 43. Openings 44 are formed at the front ends of the partition plates 42 on the odd-numbered layers, and openings 44 are formed at the rear ends of the partition plates 42 on the even-numbered layers. The plurality of circulation cavities 43 are communicated through the openings 44. After the gas exhaled by the patient enters the outer shell 41, it is blocked by the partition plates 42, extending the flow path of the gas and increasing the heat exchange time between the gas and the oxygen in the spiral pipe 23, facilitating the full heat exchange between the gas exhaled by the patient and the oxygen in the spiral pipe 23.

[0055] In addition to having temperature, the gas exhaled by the patient also contains water vapor. At body temperature (about 37 °C), the absolute humidity of the exhaled gas is close to 44 mg / L (that is, each liter of gas contains 44 mg of water). In order to recover the water in the exhaled gas and continue to recover the temperature in the gas, as Figure 3 , Figure 4 , Figure 6 and Figure 7 shown, the passive warming and humidifying assembly 4 further includes a water collection assembly 6 provided at the top inside the water cavity 32. The water collection assembly 6 includes a partition plate 61 fixed to the top inside the outer box 31 close to one side of the passive warming and humidifying assembly 4. A water collection member 62 is fixed inside the partition plate 61. The water collection member 62 can be made of a biomimetic water collection material. The biomimetic water collection material is a special functional material inspired by natural organisms, which can efficiently collect water vapor, fog or dew in the air. Its core principle is to achieve the rapid condensation, directional transportation and efficient collection of droplets by mimicking the micro-nano structure and wettability regulation on the surface of organisms.

[0056] A through hole 39 is formed on one side of the outer box 31 close to the outer shell 41. The partition plate 61 is communicated with the uppermost circulation cavity 43 inside the outer shell 41 through the through hole 39. An exhaust pipe 64 communicated with the partition plate 61 is provided at the rear end of the outer box 31. A waterproof and breathable membrane 66 for blocking moisture is fixed inside the installation cylinder 65. The installation cylinder 65 and the exhaust pipe 64 can be detachably connected through structures such as threads, facilitating the replacement of the installation cylinder 65;

[0057] The gas after heat exchange inside the outer shell 41 enters the partition plate 61, and the moisture in the gas is collected by the water collecting member 62, and then the gas is discharged through the exhaust pipe 64. At the same time, the partition plate 61 is made of materials with good heat properties such as copper and aluminum, which is convenient for the temperature of the gas in the partition plate 61 to be conducted into the water chamber 32, and is beneficial to reducing the energy consumption of the electric heating tube 34.

[0058] A water outlet pipe 63 is also fixed at the inner bottom end of the partition plate 61. An electric valve is fixed on the water outlet pipe 63, and a float switch for controlling the opening and closing of the electric valve is fixed inside the partition plate 61.

[0059] In addition, as Figures 1-4 shown, a temperature monitoring component 8 is fixed on one side of the top end of the outer box 31 close to the outer shell 41. The temperature monitoring component 8 includes a hollow cylinder 81. The hollow cylinder 81 is located between the delivery pipe 21 and the connecting pipe 22, and the delivery pipe 21, the hollow cylinder 81 and the connecting pipe 22 are communicated in sequence. A temperature sensor 82 is fixed at the top end of the hollow cylinder 81 for monitoring the temperature of the oxygen after heat exchange with the exhaled gas.

[0060] A temperature and humidity monitoring mechanism 9 is fixed on one side of the top end of the outer box 31 away from the outer shell 41. The temperature and humidity monitoring mechanism 9 includes a hollow cylinder 91. The hollow cylinder 91 is located between the intake pipe 2 and the delivery pipe 21, and the intake pipe 2, the hollow cylinder 91 and the delivery pipe 21 are communicated in sequence. A temperature and humidity sensor 92 is fixed at the top end of the hollow cylinder 91 for monitoring the temperature and humidity of the oxygen delivered to the oxygen inhalation mask 1.

[0061] The working principle of the present invention for humidifying and oxygenating the patient's airway is as follows:

[0062] I. Active heating and humidifying of oxygen: First, sterile distilled water is added to the water chamber 32 of the outer box 31 through the water inlet pipe 36, and then the oxygen connection pipe 24 is connected to the oxygen pipe of the oxygen tank. The electric heating tube 34 is started to heat the water in the water chamber 32. The generated water vapor enters the delivery pipe 21 through the air pipe 35. At the same time, oxygen is delivered to the delivery pipe 21 through the spiral pipe 23 and the connecting pipe 22. Then the oxygen carrying water vapor is delivered to the oxygen inhalation mask 1 through the intake pipe 2. As Figure 8 shown ( Figure 8 the white arrow in is the oxygen flow direction, and the black arrow is the water vapor flow direction), when the patient inhales, the humidified oxygen enters the patient's airway, realizing humidification of the patient's airway, ensuring the patency of the patient's artificial airway, and being able to promote the clearance of secretions and reduce the risk of lung infection.

[0063] II. Passive oxygen heating and humidification: When the patient exhales, the exhaled gas enters the outlet pipe 5, and then the gas enters the passive heating and humidification component 4 after being sterilized by the air treatment device and exchanges heat with the oxygen in the spiral pipe 23 (the temperature of the gas exhaled by the human body is usually slightly lower than the body temperature, generally between 34 - 36 °C), achieving passive heating. Since the oxygen is pre-heated, the time and power consumption for the subsequent electric heating tube 34 to heat the water to the required temperature are reduced, which is beneficial to reducing the energy consumption of the electric heating tube 34 and saving costs;

[0064] Then, the gas after heat exchange in the housing 41 enters the partition plate 61 through the through hole 39, and the water in the gas is collected by the water collecting member 62, and the water flows into the partition plate 61 for collection, and the gas is discharged through the exhaust pipe 64. At the same time, the temperature of the gas in the partition plate 61 is transmitted into the water chamber 32, so that the time and power consumption for the electric heating tube 34 to heat the water to the required temperature are further reduced, and the energy consumption of the electric heating tube 34 is further reduced;

[0065] When the water level in the partition plate 61 rises to the set liquid level of the float switch, the electric valve on the water outlet pipe 63 opens, and the water in the partition plate 61 falls into the water chamber 32. The temperature of this water is transmitted into the water chamber 32, so that the time and power consumption for the electric heating tube 34 to heat the water to the required temperature are further reduced, and the energy consumption of the electric heating tube 34 is further reduced. At the same time, the recycled water can be heated to generate water vapor and then enter the delivery pipe 21, and then the oxygen carries this water vapor and is transported to the oxygen inhalation mask 1 through the inlet pipe 2, achieving passive humidification, as Figure 9 shown ( Figure 9 the black arrow in is the flow direction of the exhaled gas, and the white arrow is the flow direction of the recycled water and water vapor);

[0066] In addition, the frequency of adding water to the water chamber 32 by medical staff can be reduced, reducing the workload of medical staff. At the same time, since the water is recycled and reused immediately without long-term storage, and combined with the sterilization effect of the air treatment device and the disinfection lamp, the growth of bacteria is effectively avoided, thus avoiding harm to the health of patients.

[0067] Finally, it should be noted that the electrical equipment of the present invention is all controlled by a control panel installed on the outer box 31. The control panel adopts an existing automated control system, which will not be further elaborated here.

[0068] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of the claims of the present invention.
