Description

Technical Field

[0001] This invention relates to the field of endotracheal intubation technology, and in particular to a device for humidifying endotracheal intubation in a disconnected state. Background Technology

[0002] Endotracheal intubation is a specially designed endotracheal tube used in endotracheal intubation surgery. It plays an important role in medical treatment. Usually, a ventilator needs to be connected to the intubation tube to assist the patient's breathing or control the patient's respiratory rate. It is suitable for patients who cannot breathe spontaneously or need complete respiratory control. Through the built-in heated guidewire and temperature probe, the gas temperature is monitored and adjusted in real time to ensure that the preset target temperature is reached, thereby providing effective airway humidification, helping to protect the airway mucosa, and avoiding irritation and damage caused by dry gas.

[0003] Existing technologies typically use humidifiers or connections to ventilators for humidification. However, in some scenarios, such as weaning training, a ventilator connection is unnecessary, aiming to gradually reduce reliance on the ventilator. A standalone endotracheal tube lacks humidification, leading to tracheal dryness when the patient inhales air, causing discomfort and potentially triggering complications, especially sputum crust formation causing severe airway obstruction and death. In such cases, nurses often use saline infusion into the endotracheal tube, but this increases the risk of sputum crusts dislodging into the trachea. Therefore, this application provides a device for humidifying endotracheal tubes during weaning to meet this need. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a device for humidifying endotracheal tubes in the off-ventilator state, so as to solve the problem that existing standalone tubes do not have a humidifying function, which can cause tracheal dryness when patients inhale gas, causing patient discomfort and even easily leading to a series of complications.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A device for humidifying an endotracheal tube in a disconnected state includes a humidification device and an intubation tube body. One end of the intubation tube body is provided with a detachable front end tube, and the other end of the intubation tube body is connected to the humidification device and provided with a ventilation tube. One end of the ventilation tube is fixedly connected to an air bladder component near the front end tube. The front end tube has side holes on both opposite side walls. The device also includes a processing component for processing the gas entering the intubation tube body. The processing component is connected to the front end tube.

[0007] Optionally, the processing component includes an inner tube, one end of which is fixedly connected to a fixed tube. The inner surface of the fixed tube includes a lower water-blocking ring and multiple upper water-blocking rings, the multiple upper water-blocking rings forming a step, wherein the lower water-blocking ring is the lowest point of the step, and the highest point of the step faces the opening of the front end tube. A second groove is formed between each of the multiple upper water-blocking rings, and multiple second leakage holes are formed on the surface of the multiple second grooves. A water storage cavity communicating with the multiple second leakage holes is also formed inside the fixed tube. A cotton block is installed inside the fixed tube; the cotton block can be a sponge or other permeable material. The cotton pad is made of a material with good air permeability, absorbency, and safety. Multiple curved pores are formed within the cotton pad, and the outer surface of the pad protrudes outwards to form multiple raised points that contact the second groove. When connection to a humidification device or external ventilator is not required, a humidifying solution, such as a proportionally mixed saline solution, can be injected into the water reservoir and sealed with the cotton pad. The curved pores increase the pore length, improving the contact between the gas and the cotton pad. When external gas passes through the multiple pores on the wet cotton pad, it increases the moisture content of the cotton pad. It comes into contact with oxygen, thus increasing the humidity of the gas, preventing the trachea from drying out, and further improving the humidification effect. Therefore, when a humidification device or external ventilator is not needed, the cotton pad can humidify the gas. Furthermore, the cotton pad is elastic; when installed inside the fixed tube, multiple protrusions on its surface insert into multiple second leak holes, allowing the humidifying liquid in the reservoir to contact the cotton pad, which helps maintain humidity. The cotton pad can be removed as needed; the step without the cotton pad can guide condensate flow. As the humidified gas flows within the cannula... When condensation occurs, the condensate first contacts the steps formed by multiple upper water-retaining rings inside the front tube before entering the patient's trachea. It then enters the water storage chamber through the second leakage hole on the step, preventing a large amount of condensate from entering the patient's trachea and causing a series of complications. In addition, when condensate is generated on the step, it can slide down the step step by step and enter the water storage chamber through the second groove and the second leakage hole. Since the lower water-retaining ring and multiple upper water-retaining rings are all inclined surfaces facing the second groove, the combination of the above structures can further improve the water guiding effect and facilitate the entry of condensate into the water storage chamber.

[0008] Optionally, a pair of connecting pieces are fixedly connected to the other end of the inner tube. A sleeve is fixed to the end of the pair of connecting pieces away from the inner tube, and the sleeve is fitted onto the inner tube. The end of the front tube away from the side hole is the insertion end. The front tube is fixed to the insertion end and the insertion tube body by threads. Multiple slots are opened on the peripheral side of the insertion end. Multiple insert plates are fixedly connected to the outer end of the fixed tube. The multiple insert plates and multiple slots are inserted and matched. The number of multiple slots and multiple insert plates corresponds to each other, and the height of the insert plates is lower than the height of the insertion end. The multiple insert plates and the pair of connecting pieces are all elastic structures, which helps to adjust the position during installation. During installation, the sleeve is fitted onto the inner tube, so that the connecting piece at one end of the sleeve enters the side hole through the connection between the side hole and the opening of the front tube, and the insert plate at the other end of the sleeve is inserted into the slot. At this time, the sleeve is fixed. Then, the insertion end on the front tube and the insertion tube body are screwed together. This facilitates disassembly, cleaning, and replacement of parts. The installation method is not limited to the above structure.

[0009] Optionally, an outlet pipe is fixedly connected to the end of the inner tube away from the fixed tube. Multiple dispersion holes are formed on the circumferential side of the outlet pipe, which is located between two side holes. These dispersion holes are evenly distributed on the circumferential side of the outlet pipe. Therefore, when humidifying gas exits from the inner tube through the outlet pipe, it can exit not only through the outlet pipe opening but also through the multiple evenly distributed dispersion holes, facilitating uniform humidification when the humidifying gas is introduced into the air tube. The inner tube includes a recessed portion, which has a V-shaped structure. Multiple first leakage holes are formed on the surface of the recessed portion, communicating with the interior of the inner tube. The first leakage holes are located at the lowest point of the V-shaped structure. The inner surface of the inner tube and the outer surface of the front end tube are both burred surfaces, and a first... The two-chamber design allows sputum to slide gradually along the V-shaped slope of the inner tube towards the first leak hole, eventually entering the second chamber through the first leak hole. This reduces the amount of sputum remaining in the inner tube and its impact on ventilation. Because sputum is viscous, the roughened surface of the second chamber reduces its flowability, preventing it from rapidly flowing out of the second chamber and re-entering the trachea when the tube is removed. Furthermore, the V-shaped structure on the inner tube surface facilitates the drainage of condensate from the tube wall, further improving condensate collection. The surface of the tube body has a groove adapted to the size of the ventilation tube. The ventilation tube is secured in the groove, and when the tube body is in the groove, its height does not exceed the tube body, thus not affecting the insertion of the tube.

[0010] Optionally, the airbag component is fixedly sleeved on the outer periphery of the cannula. The airbag component includes an airbag, the peripheral side of which is concave inward to form a folded portion. An outer airbag ring is fixedly connected to the outer wall of the airbag, and an inner airbag ring is fixedly connected to the inner wall of the airbag. A first cavity is formed between the inner and outer airbag rings. By providing a foldable airbag, with the outer wall of the airbag being the outer airbag ring and the inner wall being the inner airbag ring, and the outer and inner airbag rings communicating, when the airbag expands, it can cause the outer and inner airbag rings on its surface to expand, thereby opening the first cavity. When phlegm is present on the inner wall of the trachea... When the fluid slides into the first cavity, it is collected. After the shape of the airbag is restored, the first cavity is not in a completely closed state. At the same time, since multiple protrusions are fixedly connected to the inner surface of the outer ring and a first groove that matches the size of the multiple protrusions is fixedly connected to the inner surface of the inner ring, the distance between the multiple protrusions can be shortened when the airbag is restored and contracted, so that the multiple protrusions fit together and form a circular block structure. When the circular block formed by the multiple protrusions fits together with the first groove, the opening of the first cavity can be closed, thereby preventing sputum leakage when the intubation body is removed later.

[0011] Compared with the prior art, the present invention has at least the following beneficial effects:

[0012] In the above solution, by setting up a processing component, the humidity of the gas entering the trachea can be increased when there is no need to connect to a humidification device or an external ventilator, thus preventing the trachea from drying out; it can also collect condensate when it needs to be connected to a humidification device or an external ventilator, reducing the amount of condensate entering the trachea, thereby facilitating use in the weaning state or mechanical ventilation state.

[0013] By incorporating an airbag component, sputum that has slipped into the first cavity from the inner wall of the trachea can be collected; and the airbag component can keep the intubation tube fixed inside the trachea, thus stabilizing the position of the treatment component.

[0014] By incorporating an inner tube, sputum entering the inner tube can be diverted, reducing the amount of sputum remaining in the inner tube and affecting ventilation. In conjunction with the aforementioned processing components, it further enhances the collection capacity of condensate, reducing the amount of condensate entering the trachea. Additionally, the multiple evenly distributed dispersion holes on the inner tube help to uniformly humidify the humidified gas as it is circulated into the trachea. In summary, the intubation humidification process has been optimized to meet different clinical needs. Attached Figure Description

[0039] Example 1

[0040] like Figures 1 to 4 As shown, an embodiment of the present invention provides a device for humidifying endotracheal intubation in a disconnected state, including a humidification device 1 and an intubation body 2. Both the humidification device 1 and the intubation body 2 are prior art. One end of the intubation body 2 is provided with a detachable front end tube 6, and the other end of the intubation body 2 is connected to the humidification device 1 and is provided with a ventilation tube 5. Both the intubation body 2 and the ventilation tube 5 are made of medical-grade polymer materials in the prior art, which have good biocompatibility and flexibility. One end of the ventilation tube 5 is fixedly connected to an air bladder component 7 near the front end tube 6. The front end tube 6 has side holes 8 on both sides of its opposite side walls, and the two side holes 8 communicate with the opening of the front end tube 6. It also includes a processing component for processing the gas entering the intubation body 2. The processing component is connected to the front end tube 6.

[0041] The processing assembly includes an inner tube 11, one end of which is fixedly connected to a fixed tube 14. The inner surface of the fixed tube 14 includes a lower water-blocking ring 31 and multiple upper water-blocking rings 30, which form a step. The lower water-blocking ring 31 is the lowest point of the step, and the highest point of the step faces the opening of the front end tube 6. A second groove 32 is formed between the multiple upper water-blocking rings 30, and multiple second leakage holes 33 are formed on the surface of the multiple second grooves 32. A water storage chamber 34 communicating with the multiple second leakage holes 33 is also formed inside the fixed tube 14. When connected to the humidification device 1 or an external ventilator, the steps on the inner wall of the fixed tube 14 can guide the condensate. The process is as follows: when the humidifying gas flows through the intubation tube body 2, condensation is generated. Before entering the patient's trachea, the condensation will first come into contact with the steps formed by multiple upper water-blocking rings 30 in the front tube 6, and enter the water storage chamber 34 through the second leakage hole 33 on the steps, preventing a large amount of condensation from entering the patient's trachea and causing a series of complications. In addition, when condensation is generated on the steps, the condensation can slide down the steps step by step and enter the water storage chamber 34 through the second groove 32 and the second leakage hole 33. Since the lower water-blocking ring 31 and multiple upper water-blocking rings 30 are all inclined surfaces facing the second groove 32, the cooperation of the above structures can further improve the water guiding effect and facilitate the entry of condensation into the water storage chamber 34.

[0042] Example 2

[0043] like Figure 4 , Figure 7 and Figure 11 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0044] A cotton block 16 is installed inside the fixed tube 14. The cotton block can be replaced by a sponge or other materials with good air permeability, water absorption, and safety. Multiple air holes 35 are formed inside the cotton block 16, and each air hole 35 is curved. Multiple protrusions 36 are formed on the outer periphery of the cotton block 16, and these protrusions 36 abut against the second groove 32. When there is no need to connect it to the humidification device 1 or an external ventilator, a humidifying liquid, such as a proportionally mixed saline solution, can be injected into the water storage chamber 34 using a syringe, and then sealed with the cotton block 16, causing the cotton block 16 to be stuck inside the fixed tube 14. External air flows out through the multiple protrusions on the wet cotton block 16. When the vent 35 passes through, it increases the contact between the moisture in the cotton block 16 and the oxygen, thereby increasing the humidity of the gas and preventing the trachea from drying out. The curved hole increases the hole length and improves the contact between the gas and the cotton block 16, thereby further improving the humidification effect of the gas. Therefore, when it is not necessary to connect to the humidification device 1 or an external ventilator, the cotton block 16 can humidify the gas. In addition, the cotton block 16 is elastic. When the cotton block 16 is installed in the fixed tube 14, the multiple protrusions 36 on the surface of the cotton block 16 are inserted into the multiple second leakage holes 33, so that the humidifying liquid in the water storage chamber 34 comes into contact with the cotton block 16, which helps the cotton block 16 maintain humidity.

[0045] like Figure 12 , Figure 13 and Figure 15 As shown, a pair of connecting pieces 10 are fixedly connected to the other end of the inner tube 11. A sleeve 15 is fixed to the end of the pair of connecting pieces 10 away from the inner tube 11, and the sleeve 15 is fitted onto the inner tube 11. The end of the front tube 6 away from the side hole 8 is the insertion end 27. The front tube 6 is threadedly fixed to the insertion tube body 2 via the insertion end 27. Multiple slots 28 are provided on the circumferential side of the insertion end 27. Multiple insert plates 29 are fixedly connected to the outer end of the fixed tube 14. The multiple insert plates 29 and multiple slots 28 are inserted into each other. The number of slots 28 and multiple insert plates 29 corresponds to each other, and the number of insert plates 29 is... The height of section 9 is lower than that of the insertion end 27. Multiple insertion plates 29 and a pair of connecting pieces 10 are elastic structures, which helps to adjust the position during installation. During installation, the sleeve 15 is fitted onto the inner tube 11, so that the connecting piece 10 at one end of the sleeve 15 enters the side hole 8 through the opening of the side hole 8 and the front tube 6. The insertion plate 29 at the other end of the sleeve 15 is inserted into the slot 28. At this time, the sleeve 15 is fixed. Then, the insertion end 27 on the front tube 6 and the insertion tube body 2 are screwed together. This facilitates disassembly, cleaning, and replacement of parts. The installation method is not limited to the above structure.

[0046] like Figure 12As shown, the end of the inner tube 11 away from the fixed tube 14 is also fixedly connected to an air outlet pipe 12. Multiple dispersion holes 13 are opened on the circumferential side of the air outlet pipe 12. The air outlet pipe 12 is located between two side holes 8. The multiple dispersion holes 13 are evenly distributed on the circumferential side of the air outlet pipe 12. Therefore, when the humidifying gas exits from the inner tube 11 through the air outlet pipe 12, it can not only exit through the opening of the air outlet pipe 12, but also through the multiple evenly distributed dispersion holes 13, which helps to achieve uniform humidification when the humidifying gas is introduced into the air pipe.

[0047] like Figure 8 and Figure 10 As shown, the airbag component 7 is fixedly sleeved on the outer periphery of the sleeve 15. The airbag component 7 includes an airbag 37, with the peripheral side of the airbag 37 recessed inward to form a folded portion 22. An outer airbag ring 18 is fixedly connected to the outer wall of the airbag 37, and an inner airbag ring 17 is fixedly connected to the inner wall of the airbag 37. A first cavity 19 is formed between the inner airbag ring 17 and the outer airbag ring 18. By providing a foldable airbag 37, with the outer wall of the airbag 37 being the outer airbag ring 18 and the inner wall of the airbag 37 being the inner airbag ring 17, and the outer airbag ring 18 and the inner airbag ring 17 communicating, when the airbag 37 expands, it can drive the outer airbag ring 18 and the inner airbag ring 17 on its surface to expand, causing the first cavity 19 to open. When sputum from the tracheal wall slides into the first cavity 19, it is collected. After the shape of the air bag 37 is restored, the first cavity 19 is not completely closed. At the same time, since multiple protrusions 20 are fixedly connected to the inner surface of the outer bag ring 18, and a first groove 21 that matches the size of the multiple protrusions 20 is fixedly connected to the inner surface of the inner bag ring 17, the air bag 37 can shorten the distance between the multiple protrusions 20 when it is restored and contracted, so that the multiple protrusions 20 can fit together and form a circular block structure. When the circular block formed by the multiple protrusions 20 fits together with the first groove 21, the opening of the first cavity 19 can be closed to prevent sputum leakage when the intubation tube body 2 is removed later.

[0048] like Figure 12 and Figure 14As shown, the inner tube 11 includes a recessed portion 26, which has a V-shaped structure. Multiple first leakage holes 23 are formed on the surface of the recessed portion 26, and these holes communicate with the interior of the inner tube 11. The first leakage holes 23 are located at the lowest point of the V-shaped structure. The inner surface of the inner tube 11 and the outer surface of the front end tube 6 are both burred surfaces 25. A second cavity 24 is formed between the inner tube 11 and the insertion tube body 2. When sputum enters the inner tube 11, it can gradually flow along the inclined surface of the V-shaped structure towards the first leakage holes 23. The tube slides in through three points and finally enters the second cavity 24 through the first leak hole 23, reducing the amount of sputum remaining in the inner tube 11 and affecting the ventilation effect. Since the sputum is viscous, after the sputum enters the second cavity 24, the burr surface 25 inside the second cavity 24 can reduce the flow of the sputum, preventing the sputum from flowing out of the second cavity 24 quickly and re-entering the trachea when the tube body 2 is removed. In addition, the V-shaped structure on the surface of the inner tube 11 is conducive to the drainage of condensate from the tube wall, further improving the condensate collection capacity.

[0049] like Figure 5 As shown, the surface of the intubation tube body 2 is provided with a groove 4 that is adapted to the size of the ventilation tube 5. The ventilation tube 5 is fixed in the groove 4. When the intubation tube body 2 is fixed in the groove 4, its height does not exceed the height of the intubation tube body 2.

[0050] The working principle of the technical solution provided by this invention is as follows: During use, depending on the clinical situation, it is selected whether to connect to the humidification device 1 or an external ventilator. When not connected to the humidification device 1 or an external ventilator, humidifying liquid is injected into the water storage chamber 34 and sealed with cotton pads 16. When external gas passes through the multiple pores 35 on the wet cotton pad 16, the moisture in the cotton pad 16 comes into contact with oxygen, thereby increasing the humidity of the gas and preventing the trachea from drying out. The curved holes increase the hole length, improving the flow of gas and cotton pad 16. The cotton block 16 can humidify the gas by contacting the humidifier 1 or an external ventilator. In addition, the cotton block 16 is elastic. When the cotton block 16 is installed in the fixed tube 14, the multiple protrusions 36 on the surface of the cotton block 16 are inserted into the multiple second leak holes 33, so that the humidifying liquid in the water storage chamber 34 comes into contact with the cotton block 16, which helps the cotton block 16 maintain humidity. The above-mentioned humidification component can provide humidification when it is not connected to the humidifier 1 or an external ventilator.

[0051] When connecting to the humidification device 1 or an external ventilator, first remove the cotton pad 16. The step without the cotton pad 16 can guide the condensate. When the humidified gas flows in the tube body 2, condensate is generated. Before entering the patient's trachea, the condensate will first contact the step formed by multiple upper water-blocking rings 30 in the front tube 6, and enter the water storage chamber 34 through the second leakage hole 33 on the step, preventing a large amount of condensate from entering the patient's trachea and causing a series of complications. In addition, when condensate is generated on the step, the condensate can slide down the step step by step and enter the water storage chamber 34 through the second groove 32 and the second leakage hole 33. Since the lower water-blocking ring 31 and multiple upper water-blocking rings 30 are all inclined surfaces facing the second groove 32, it is convenient for condensate to enter the water storage chamber 34. The above-mentioned humidification components can collect condensate when connected to the humidification device 1 or an external ventilator, reducing the amount of condensate entering the trachea.

[0052] After the intubation tube 2 is inserted, the cuff 37 is expanded through the ventilation tube 5. When the cuff 37 expands, it can cause the outer cuff ring 18 and the inner cuff ring 17 on its surface to expand, so that the first cavity 19 opens. When the sputum on the inner wall of the trachea slides into the first cavity 19, it can be collected. After the air is released through the ventilation tube 5 and the cuff 37 returns to its original shape, the first cavity 19 is not in a completely closed state. At the same time, since multiple protrusions 20 are fixedly connected to the inner surface of the outer cuff ring 18, and the inner surface of the inner cuff ring 17 is fixedly connected to the first groove 21 that matches the size of the multiple protrusions 20, after the cuff 37 returns to its original shape and contracts, the multiple protrusions 20 and the first groove 21 fit together, so that the opening of the first cavity 19 is closed, preventing sputum leakage when the intubation tube 2 is removed.

[0053] When sputum enters the inner tube 11, it can gradually slide along the inclined surface of the V-shaped structure towards the first leak hole 23, and finally enter the second cavity 24 through the first leak hole 23, reducing the amount of sputum remaining in the inner tube 11 and affecting the ventilation effect. Since sputum is viscous, after entering the second cavity 24, the burr surface 25 inside the second cavity 24 can reduce the flow of sputum, preventing the problem of sputum flowing out of the second cavity 24 quickly and re-entering the trachea when the tube body 2 is removed. In addition, the V-shaped structure on the surface of the inner tube 11 is conducive to the drainage of condensate from the tube wall, further improving the condensate collection capacity.
