Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a tracheal intubation tube for general anesthesia during surgery. Background Technology

[0002] Endotracheal intubation is a crucial technique for ensuring airway patency during general anesthesia, effectively maintaining airway openness and ensuring normal gas exchange. By inserting an endotracheal tube, endotracheal intubation not only facilitates the delivery of anesthetic drugs but also ensures patient safety during surgery. Anesthesiologists assess the patient's airway status before surgery to ensure successful intubation. With advancements in technology, the safety and success rate of endotracheal intubation have significantly improved, further guaranteeing the smooth execution of surgeries.

[0003] However, during actual dental general anesthesia surgery, if the external oxygen supply equipment malfunctions and cannot continue to supply oxygen, it is necessary to manually supply oxygen by pressing the balloon. However, during the pressing process, there will be relative shaking between the balloon and the endotracheal tube. Prolonged shaking may loosen the connection between the balloon and the endotracheal tube, preventing all the gas from entering the patient's body, reducing oxygen delivery efficiency, and increasing the risk of hypoxia. Summary of the Invention

[0004] The purpose of this invention is to solve the problem in the prior art that during the compression process, there will be relative shaking between the balloon and the endotracheal tube. Prolonged shaking may loosen the connection between the balloon and the endotracheal tube, preventing all the gas from entering the patient's body, reducing oxygen delivery efficiency, and increasing the risk of hypoxia. Therefore, this invention proposes a endotracheal intubation method for general anesthesia.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A surgical endotracheal intubation tube for general anesthesia, including a medical three-way valve, and further comprising: The connecting component is located on the outside of the air inlet end of the medical three-way valve; A limiting ring is located inside the connecting component; A sealing component, located on the side of the limiting ring near the medical three-way valve, is used to seal the internal channel of the connecting component; The locking component, located on the outside of the connecting component, can be used to quickly connect to an external manual air supply device by cooperating with the connecting component. The top support assembly is located inside the air inlet end of the locking assembly and is used in conjunction with the sealing assembly to open and close the air passages of the connecting assembly and the locking assembly. The balloon, located on the air inlet end of the locking assembly, is used for manual air supply; The ventilation tube is located on the outside of the air inlet end at the bottom of the medical three-way valve; Leak-proof components are located on the inner side of the middle section of the ventilation tube to seal between the ventilation tube and the patient's trachea and prevent air leakage. The anti-bite component, located on the top of the outer side of the airway, is used to support the patient's mouth and prevent tongue biting.

[0006] Optionally, the connecting assembly includes a connecting tube fixed to the side wall of a medical three-way valve, and the outer wall of the connecting tube has a slot.

[0007] Optionally, the sealing assembly includes slide rods fixed to both ends of the outer wall of the limiting ring near the medical three-way valve. A sealing plate is slidably connected to the outside of the slide rods. Two second springs corresponding to the slide rods are fixedly connected to the outer wall of the sealing plate near the medical three-way valve. The second springs are fixedly connected to the end of the slide rod away from the limiting ring.

[0008] Optionally, a silicone sealing ring is fixedly connected to the outer wall of the sealing plate near the limiting ring, and a first groove is formed in the middle section of the sealing plate near the limiting ring.

[0009] Optionally, the outer wall of the limiting ring near the sealing plate is provided with a second groove corresponding to the sealing plate.

[0010] Optionally, the outer wall of the middle section of the sleeve has evenly distributed through holes, the two ends of the through hole opening are designed to be constricted, a limit ball is slidably connected to the inner side of the through hole, a support ring is fixedly connected to the outer wall of the sleeve, a first spring is fixedly connected to the outer wall of the support ring near the medical three-way valve, a sliding sleeve is fixedly connected to the end of the first spring away from the support ring, an extension chamber is opened in the middle section of the inner wall of the sliding sleeve, a retaining ring is fixedly connected to the outer wall of the sleeve away from the support ring, and the retaining ring is engaged with the sliding sleeve.

[0011] Optionally, the top support assembly includes a support frame fixed to the middle section of the inner side of the sleeve tube, a top rod fixedly connected to the middle section of the outer wall of the support frame near the medical three-way valve, a top plate fixedly connected to the end of the top rod away from the support frame, and the top plate engaging with a groove opened on the outer wall of the sealing plate near the support frame.

[0012] Optionally, the leak-proof assembly includes a first air supply pipe fixed to the inner wall of the ventilator, a first airbag fixedly connected to the bottom of the first air supply pipe, and the first airbag fixedly connected to the outer wall of the bottom of the ventilator.

[0013] Optionally, the anti-bite component includes a second airbag slidably connected to the outside of the top of the air tube, and a second air supply tube is fixedly connected to the top of the second airbag.

[0014] Optionally, the outer end of the first gas pipeline is provided with a controllable one-way valve, the same as the inner side of the second gas pipeline.

[0015] Compared with the prior art, the technical solution provided by this invention has at least the following beneficial effects: In the above solution, the connecting components and locking components work together to lock and fix the connecting tube and sleeve, preventing the shaking of the external balloon during compression from affecting the connection between the balloon and the medical three-way valve. This ensures a stable connection between the endotracheal tube, balloon, and three-way valve, reduces the risk of gas leakage, improves oxygen supply efficiency, ensures complete oxygen delivery to the patient, and reduces the risk of hypoxia. At the same time, the fixed connection reduces airway damage. In addition, the stable connection also improves the safety of operation, reduces the problem of unstable oxygen supply caused by operator fatigue or improper operation, and thus ensures precise control of oxygen flow and pressure, maintains the patient's oxygenation status, and improves the safety and efficiency of the operation. By using the sealing and support components in conjunction, the internal airways of the connecting tube and sleeve can be simultaneously connected and closed during connection and disconnection. This not only ensures that the airway remains open during intubation but also effectively seals it during disconnection, preventing gas leakage and the entry of external contaminants, thereby reducing the risk of infection. It improves operational efficiency and safety, simplifies the operation steps, and reduces patient discomfort and complications. In addition, the support component provides extra support for the connecting tube and sleeve, enhancing the stability of intubation, preventing displacement of the intubation position, and ensuring airway patency. By installing an anti-bite component on the outside of the endotracheal tube, patients can be effectively prevented from unconsciously biting the endotracheal tube during general anesthesia, thus avoiding damage or displacement of the tube and ensuring a stable and unobstructed airway. This design not only reduces complications caused by endotracheal tube injury, such as airway bleeding or tracheal obstruction, but also improves patient comfort by avoiding discomfort or pain caused by biting the tube. In addition, the anti-bite component reduces the burden on medical staff in adjusting the tube position or handling tube problems, simplifies the operation process, and improves surgical efficiency and safety.

[0025] like Figures 1 to 7 As shown, an embodiment of the present invention provides an endotracheal intubation tube for general anesthesia, including a medical three-way valve 1, and further comprising: The connecting component is located on the outside of the air inlet end of the medical three-way valve 1, and the connecting component is supported by the medical three-way valve 1. The limiting ring 8 is located inside the connecting component and is limited by the connecting component. A sealing component is located on the side of the limiting ring 8 near the medical three-way valve 1, used to seal the internal channel of the connecting component, and the limiting ring 8 supports the sealing component; The locking component, located on the outside of the connecting component, can be used to quickly connect to an external manual air supply device by cooperating with the connecting component. The top support assembly is located inside the air inlet end of the locking assembly and is used in conjunction with the sealing assembly to open and close the air passages of the connecting assembly and the locking assembly. The balloon 6 is located on the air inlet end of the locking assembly and is used for manual air supply; The ventilation tube 11 is located on the outside of the air inlet end at the bottom of the medical three-way valve 1. The ventilation tube 11 is inserted into the patient's trachea to support the airway and deliver breathing gas to the lungs. A leak-proof component is located on the inner side of the middle section of the ventilation tube 11 to seal the ventilation tube 11 and the patient's trachea to prevent air leakage. The anti-bite component is located on the top of the outer side of the airway 11 to support the patient's mouth and prevent tongue biting.

[0026] The connecting assembly includes a connecting pipe 3 fixed to the side wall of the medical three-way valve 1. The connecting pipe 3 is supported and fixed by the medical three-way valve 1. A groove 31 is provided on the outer wall of the connecting pipe 3.

[0027] The sealing assembly includes slide rods 81 fixed to both ends of the outer wall of the limiting ring 8 near the medical three-way valve 1. The limiting ring 8 supports and fixes the slide rods 81 on both sides. A sealing plate 83 is slidably connected to the outer side of the slide rods 81. The slide rods 81 limit the sealing plate 83 on both sides, allowing the sealing plate 83 to slide along the slide rods 81 on the outer side. Two second springs 82 corresponding to the slide rods 81 are fixedly connected to the outer wall of the sealing plate 83 near the medical three-way valve 1. The second springs 82 are fixedly connected to the end of the slide rod 81 away from the limiting ring 8. The second springs 82 push the sealing plate 83 towards the limiting ring 8 with the end of the slide rod 81 away from the limiting ring 8 as the stress point.

[0028] A silicone sealing ring is fixedly connected to the outer wall of the sealing plate 83 near the limiting ring 8. The silicone sealing ring can increase the sealing between the limiting ring 8 and the sealing plate 83. A first groove is provided in the middle section of the sealing plate 83 near the limiting ring 8.

[0029] The outer wall of the limiting ring 8 near the sealing plate 83 has a second groove corresponding to the sealing plate 83. The second groove on the limiting ring 8 can engage with the sealing plate 83, making the connection area between the limiting ring 8 and the sealing plate 83 larger and the connection more stable.

[0030] The engaging assembly includes a sleeve 4 that slides outside the connecting tube 3. The connecting tube 3 supports and limits the sleeve 4. The outer wall of the middle section of the sleeve 4 has evenly distributed through holes 41. The two ends of the opening of the through holes 41 are designed to be tapered. A limiting ball 42 is slidably connected to the inner side of the through hole 41. The tapering on both sides of the through hole 41 allows the limiting ball 42 to slide freely inside the through hole 41 without falling out. A support ring 43 is fixedly connected to the outer wall of the sleeve 4. The sleeve 4 supports and fixes the support ring 43. A first spring 44 is fixedly connected to the outer wall of the support ring 43 on the side near the medical three-way valve 1. The first spring 44 is supported and fixed by the support ring 43. A sliding sleeve 5 is fixedly connected to the end of the first spring 44 away from the support ring 43. The first spring 44 pushes the sliding sleeve 5 towards the medical three-way valve 1 with the support ring 43 as the stress point. An extension chamber 51 is opened in the middle section of the inner wall of the sliding sleeve 5. The extension chamber 51 increases the stroke of the limiting ball 42 to move outward. A retaining ring 45 is fixedly connected to the outer wall of the sleeve 4 away from the support ring 43. The retaining ring 45 is supported and fixed by the sleeve 4. The retaining ring 45 is engaged with the sliding sleeve 5 and blocks the sliding sleeve 5.

[0031] The top support assembly includes a support frame 7 fixed to the middle section of the inner side of the sleeve 4. The sleeve 4 supports and fixes the support frame 7. A top rod 71 is fixedly connected to the middle section of the outer wall of the support frame 7 near the medical three-way valve 1. The support frame 7 supports and fixes the top rod 71. A top plate 72 is fixedly connected to the end of the top rod 71 away from the support frame 7. The top plate 72 is supported and fixed by the top rod 71. The top plate 72 is engaged with a groove on the outer wall of the sealing plate 83 near the support frame 7. The groove on the outer side of the sealing plate 83 cooperates with the top plate 72 to push the sealing plate 83 more stably and prevent side slippage.

[0032] The leak-proof assembly includes a first air supply tube 12 fixed to the inner wall of the ventilation tube 11. The first air supply tube 12 is supported and fixed by the ventilation tube 11. A first air bag 13 is fixedly connected to the bottom of the first air supply tube 12. The first air bag 13 is fixedly connected to the outer wall of the bottom of the ventilation tube 11. The first air bag 13 is supported and fixed by the ventilation tube 11. At the same time, gas is delivered into the first air bag 13 through the first air supply tube 12 to inflate the first air bag 13 and fit it against the patient's trachea.

[0033] The anti-bite component includes a second airbag 2 slidably connected to the outer side of the top of the air tube 11. A second air supply tube 21 is fixedly connected to the top of the second airbag 2. The air tube 11 limits the second airbag 2, allowing the second airbag 2 to slide on the air tube 11. Air can be delivered into the second airbag 2 through the second air supply tube 21. The second airbag 2 supports the patient's mouth, preventing the patient from biting the air tube 11 or biting their tongue in an emergency.

[0034] The outer end of the first air supply pipe 12 is provided with a controllable one-way valve that is the same as the inner side of the second air supply pipe 21. By controlling the one-way valve, the gas in the first airbag 13 and the second airbag 2 can be discharged after use, making it convenient to remove the air tube 11.

[0035] The working process of the technical solution provided by this invention is as follows: When using this invention, firstly, the ventilation tube 11 is inserted into the patient's trachea, and then air is delivered into the first air bag 13 through the first air delivery tube 12, which inflates the first air delivery tube 12 and makes the first air bag 13 fit against the patient's tracheal wall, thereby avoiding air leakage during the delivery process. After the ventilation tube 11 is fixed, the second air bag 2 is pushed into the patient's mouth, and air is injected into the second air bag 2 through the second air supply tube 21 to inflate the second air bag 2, thereby supporting the patient's mouth and preventing the patient from biting the tube or biting the tongue during use. After the external gas supply equipment malfunctions and can no longer supply gas, it is necessary to rotate the medical three-way valve 1 to connect the side air inlet end of the medical three-way valve 1 with the bottom air pipe 11. Then, push the sliding sleeve 5 away from the retaining ring 45. The sliding sleeve 5 drives the extension chamber 51 to move towards the support ring 43, so that the extension chamber 51 is aligned with the through hole 41 and the first spring 44 is compressed. Then, the sleeve 4 is sleeved on the outside of the connecting pipe 3, so that the groove 31 is aligned with the through hole 41. Then, release the sliding sleeve 5. The first spring 44 pushes the sliding sleeve 5 towards the retaining ring 45 with the support ring 43 as the stress point. The extension chamber 51 squeezes the limiting ball 42, forcing the limiting ball 42 to move inward towards the through hole 41 and engage with the groove 31, thereby connecting and fixing the connecting pipe 3 and the sleeve 4. During the process of attaching the sleeve 4 to the outside of the connecting tube 3, the sleeve 4 drives the support frame 7 to move synchronously. At the same time, the support frame 7 uses the push rod 71 to drive the top plate 72 to move, so that the top plate 72 engages with the groove on the sealing plate 83 and supports the sealing plate 83, causing the sealing plate 83 to move away from the limiting ring 8. At the same time, the second spring 82 is compressed, thereby canceling the engagement between the sealing plate 83 and the limiting ring 8, allowing the gas in the sleeve 4 to be delivered into the connecting tube 3, and then into the ventilation tube 11 through the medical three-way valve 1, and into the patient's body.
