Description

Technical Field

[0001] The present invention relates to the technical field of endotracheal intubation for severe pneumonia, and particularly relates to a humidifying device for endotracheal intubation in severe pneumonia. Background Art

[0002] The severity of pneumonia depends on the degree of local inflammation, the spread of pulmonary inflammation, and the degree of systemic inflammatory response. For example, if a pneumonia patient presents with severe hypoxemia or acute respiratory failure requiring ventilation support, or shows manifestations of circulatory failure such as hypotension and shock, and other organ dysfunctions, it can be identified as severe pneumonia. Severe pneumonia will have manifestations of respiratory failure. Therefore, it is necessary to intubate patients with severe pneumonia. By inserting the trachea into the patient's body, it is ensured that sufficient oxygen can be maintained in the patient's body.

[0003] During the normal breathing process, dry and cold air becomes gradually moist and warm after flowing through the upper respiratory tract to facilitate gas exchange in the alveoli. Under normal circumstances, the respiratory tract must maintain a certain humidity to ensure the normal movement of cilia and mucus secretion. The gas introduced into the human body through the artificial airway loses the normal heating and humidifying function of the human body, which will bring great discomfort to the patient. After conventional severe pneumonia patients undergo endotracheal intubation, it is necessary to heat and humidify the delivered gas. The traditional heating and humidifying device connects a heating humidifier to one end of the ventilator, and the oxygen is heated and humidified by the heating humidifier.

[0004] The heating humidifier energizes the heating rod, and the heating rod heats the sterile water. When oxygen enters the heated sterile water, the oxygen can be humidified and heated. When the sterile water humidifies the oxygen, the sterile water is in a continuous consumption state. Therefore, the amount of sterile water in the heating humidifier will decrease over time. It is necessary to regularly observe the amount of sterile water in the heating humidifier and regularly add sterile water to the heating humidifier. If the sterile water is not added in time, it will cause the heating rod to dry burn. The dry-burning heating rod is prone to overheating risks and will also make the oxygen drier. Based on the above problems, the present application proposes a humidifying device for endotracheal intubation in severe pneumonia. Summary of the Invention

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Refer to Figure 1-8, A humidifying device for tracheal intubation in severe pneumonia, comprising a heating and humidifying box 1. A oxygen outlet pipe 2 is fixedly arranged at the top of the heating and humidifying box 1. A heating rod 3 is fixedly arranged inside the heating and humidifying box 1. An oxygen inlet pipe 4 is fixedly arranged on the left side wall of the heating and humidifying box 1. Oxygen inlet holes 5 are arranged through the surface of the oxygen inlet pipe 4. An intake assembly is fixedly arranged at the intake end of the oxygen inlet pipe 4. A liquid level detection assembly for facilitating the detection of the liquid level inside it is arranged inside the heating and humidifying box 1. A sterile water inlet assembly for facilitating the addition of sterile water into it is arranged on the right side of the heating and humidifying box 1. A height adjustment assembly for facilitating the adjustment of its height is arranged at the bottom of the heating and humidifying box 1. The liquid level detection assembly includes a protective shell 13 fixedly installed on the left side of the heating and humidifying box 1. A sliding rheostat 14 is arranged inside the protective shell 13. The sliding rheostat 14 is fixedly installed on the left side of the heating and humidifying box 1. A sliding piece is arranged on the sliding rheostat 14. A connecting block 15 is installed on the surface of the sliding rheostat 14 through the sliding piece. A moving rod 16 is fixedly arranged at the top of the connecting block 15. The moving rod 16 is slidably arranged inside the protective shell 13. A moving plate 17 is fixedly arranged at the top of the moving rod 16. A vertical connecting rod 18 is fixedly arranged at the bottom of the moving plate 17. The vertical connecting rod 18 is slidably arranged inside the heating and humidifying box 1. A buoyancy ball 19 is fixedly arranged at the bottom end of the vertical connecting rod 18. The buoyancy ball 19 is made of medical plastic. The inside of the buoyancy ball 19 is hollow. The buoyancy ball 19 is located inside the heating and humidifying box 1. The buoyancy ball 19 made of medical plastic with a hollow inside has better buoyancy, avoiding the situation that the buoyancy ball 19 has too small buoyancy during the moving process and enters the water, resulting in the sliding rheostat 14 being unable to reach the stop resistance value. The sterile water inlet assembly includes a water outlet pipe 20 fixedly installed on the left side of the heating and humidifying box 1. A connecting pipe 21 is fixedly arranged at the left end of the water outlet pipe 20. A water inlet pipe 22 is fixedly arranged on the left side of the connecting pipe 21. A mounting plate 23 is fixedly arranged inside the connecting pipe 21. A connecting frame 24 is fixedly arranged on the right side of the mounting plate 23. A mounting shaft 25 is fixedly arranged inside the connecting frame 24. A blocking plate 26 is rotatably arranged on the surface of the mounting shaft 25. The blocking plate 26 is located inside the connecting pipe 21. The blocking plate 26 is made of medical rubber. The blocking plate 26 made of medical rubber has a certain elasticity, making the sealing of the blocking plate 26 to the mounting plate 23 better, and the medical rubber is safer to use. When the liquid level of the sterile water drops, the buoyancy ball 19 drives the moving rod 16 to move downward through the vertical connecting rod 18 and the moving plate 17, so that the connecting block 15 drives the sliding piece to slide on the sliding rheostat 14. When the resistance value of the sliding rheostat 14 decreases to the minimum preset value, an external conveying device conveys the sterile water into the water inlet pipe 22. The sterile water enters the connecting pipe 21 through the water inlet pipe 22, so that the sterile water pushes the blocking plate 26 to flip on the surface of the mounting shaft 25, and the sterile water enters the heating and humidifying box 1 through the water outlet pipe 20. As the liquid level rises, the buoyancy ball 19 drives the moving rod 16 to move upward through the vertical connecting rod 18 and the moving plate 17, so that the connecting block 15 drives the sliding piece of the sliding rheostat 14 to move upward.When the resistance value of the sliding rheostat 14 reaches the maximum preset value, the delivery of sterile water is stopped. Under the action of gravity, the baffle plate 26 contacts the mounting plate 23, which can block the backflow of sterile water, thus avoiding insufficient sterile water in the heating and humidifying box 1 resulting in the inability to humidify oxygen, avoiding dry burning and damage of the heating rod 3 due to the absence of sterile water in the heating and humidifying box 1, and avoiding the oxygen delivered becoming drier during the dry burning process of the heating rod 3.

[0030] Specifically, the air inlet assembly includes a connecting elbow 6 fixedly installed at the air inlet end of the oxygen inlet pipe 4. A connecting box 7 is fixedly arranged at the top of the connecting elbow 6. An oxygen inlet pipe 8 is fixedly arranged at the top of the connecting box 7. A mounting frame 9 is fixedly arranged inside the connecting box 7. A spring 10 is fixedly arranged at the top of the mounting frame 9. The top end of the spring 10 is fixedly provided with a switching plate 11. A connecting plate 12 is lapped on the surface of the switching plate 11, and the connecting plate 12 is fixedly installed inside the connecting box 7. The oxygen inlet pipe 8 is connected to the oxygen supply device through a delivery hose. The oxygen supply device delivers oxygen into the oxygen inlet pipe 8 through the delivery hose. The oxygen enters the inside of the connecting box 7 through the oxygen inlet pipe 8. The oxygen pushes the switching plate 11 to move downward, causing the switching plate 11 to compress the spring 10, and the switching plate 11 moves out of the connecting plate 12. The oxygen entering the connecting box 7 is delivered to the oxygen inlet pipe 4 through the connecting elbow 6 and is delivered to the water in the heating and humidifying box 1 through the oxygen inlet holes 5 on the surface of the oxygen inlet pipe 4. The water in the heating and humidifying box 1 is heated by the heating rod 3 to keep the water in the heating and humidifying box 1 at an appropriate temperature. The oxygen entering the heating and humidifying box 1 is uniformly dispersed in the warm water in the form of tiny bubbles. The oxygen is humidified and heated by the warm water. The heated and humidified oxygen enters above the heating and humidifying box 1 and is delivered to the inside of the oxygen delivery pipe through the oxygen outlet pipe 2 and is delivered to the inside of the patient's breathing mask through the oxygen delivery pipe, facilitating the delivery of oxygen. Moreover, by inserting or removing the switching plate 11 from the connecting plate 12, the backflow of sterile water in the heating and humidifying box 1 into the oxygen delivery device can be avoided, thus facilitating the protection of the oxygen delivery device.

[0031] Specifically, the height adjustment component includes an adjustment column 27 fixedly installed at the bottom of the heating and humidifying box 1. An adjustment hole 28 is provided on the front side of the adjustment column 27. The number of adjustment holes 28 is several, and the several adjustment holes 28 are arranged in a linear array. A mounting sleeve 29 is slidably arranged on the surface of the adjustment column 27. A threaded hole 30 is provided through the front side of the mounting sleeve 29. A threaded knob 31 is arranged inside the threaded hole 30 in a threaded manner. The threaded knob 31 is arranged in a lapping manner with the adjustment hole 28. A moving base 32 is fixedly arranged at the bottom end of the mounting sleeve 29. A self-locking universal wheel 33 is fixedly arranged at the bottom of the moving base 32. When the height of the heating and humidifying box 1 needs to be adjusted, rotate the threaded knob 31 to move the threaded knob 31 out of the adjustment hole 28, and pull the adjustment column 27 to move inside the mounting sleeve 29, so that the adjustment column 27 drives the heating and humidifying box 1 to move upward or drives the heating and humidifying box 1 to move downward. Then, rotate the threaded knob 31 in the reverse direction to insert the threaded knob 31 into the adjustment hole 28 at another position to fix the position of the adjustment column 27, thereby adjusting the height of the heating and humidifying box 1, so that the heating and humidifying box 1 can be used in cooperation with different oxygen delivery devices. Secondly, the moving base 32 can be moved through the self-locking universal wheel 33, so that the mounting sleeve 29 drives the heating and humidifying box 1 to move through the adjustment column 27, thereby moving the position of the heating and humidifying box 1, facilitating the movement of the heating and humidifying box 1, making the handling of the heating and humidifying box 1 more convenient. Moreover, the position of the moving base 32 can be locked through the self-locking function of the self-locking universal wheel 33, and the position of the heating and humidifying box 1 can be locked through the mounting sleeve 29 and the adjustment column 27, avoiding the deviation of the heating and humidifying box 1 during the use process.

[0032] During use: As the oxygen is humidified, the sterile water in the heating and humidifying box 1 continuously decreases. When the liquid level of the sterile water drops, the buoyancy ball 19 moves downward following the liquid level, and drives the vertical connecting rod 18 to move downward through the buoyancy ball 19, so that the vertical connecting rod 18 drives the moving rod 16 to move downward through the moving plate 17, and the moving rod 16 drives the sliding piece to slide on the slide rheostat 14 through the connecting block 15. At this time, the resistance value of the slide rheostat 14 decreases. When the resistance value of the slide rheostat 14 decreases to the minimum preset value, the external conveying device conveys the sterile water into the water inlet pipe 22. The sterile water enters the connecting pipe 21 through the water inlet pipe 22, so that the sterile water pushes the blocking plate 26 to flip on the surface of the mounting shaft 25, and the sterile water enters the water outlet pipe 20 through the connecting pipe 21 and enters the heating and humidifying box 1 through the water outlet pipe 20, so that the liquid level of the sterile water in the heating and humidifying box 1 rises. As the liquid level rises, the buoyancy ball 19 pushes the vertical connecting rod 18 to move upward, so that the vertical connecting rod 18 drives the moving rod 16 to move upward through the moving plate 17, and the connecting block 15 drives the sliding piece of the slide rheostat 14 to move upward. At this time, the resistance value of the slide rheostat 14 increases. When the resistance value of the slide rheostat 14 reaches the maximum preset value, the conveyance of the sterile water stops, and the blocking plate 26 flips to the right under the action of gravity, so that the blocking plate 26 contacts the mounting plate 23, and the backflow of the sterile water can be blocked.
