Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to an endotracheal cannula with an anti-dropout teeth pad. Background Art

[0002] Endotracheal intubation is a method of inserting a special endotracheal tube into the trachea or bronchus through the oral or nasal cavity and the glottis, which provides the best conditions for airway patency, ventilation and oxygen supply, and airway suction, and is an important measure to rescue patients with respiratory dysfunction. Endotracheal intubation usually requires the use of a dental pad, which usually serves as a support for the endotracheal tube to prevent the patient from biting the endotracheal tube due to unconsciousness, irritability, etc., causing the tube to be compressed, deformed, or blocked, to ensure that the airway is unobstructed.

[0003] Prior art, such as Chinese patent "CN106377825A", provides an anti-bite tube and gum protection device for tracheal intubation, including a first sleeve with a hollow structure, the inner diameter of the first sleeve is adapted to the outer diameter of the tracheal intubation, and also includes a baffle component, which is arranged on the first sleeve to divide the first sleeve into an inner body and an outer body; a second sleeve, which is sleeved on the outer body, and its inner diameter is adapted to the outer diameter of the outer body. The beneficial effects of the invention are as follows: first, the sleeve component cooperates with the outer body on the tooth pad body to reduce the damage caused by the trachea to the patient's oral cavity in the tracheal intubation technology; second, the baffle component can prevent the tooth pad body in the oral cavity from shifting and falling out; third, the protective component increases the comfort of the tooth pad body when it is placed in the oral cavity, and reduces the damage caused by the tooth pad body to the oral cavity.

[0004] However, in actual use, after the endotracheal tube is inserted into the patient's body, one end outside the body is fixed to the patient's face with tape. Long-term use of the tape may cause the secretions on the patient's face to reduce its viscosity and cause it to fall off, making the endotracheal tube easy to slip out of the airway, causing the patient to have poor ventilation. In addition, since the dental pad is usually set on one side of the trachea for support, when the patient's mouth is closed, the force on the gums will be concentrated and unbalanced, which will reduce the comfort of the patient wearing the dental pad. In addition, when the patient's sputum is more viscous or more, it is easy to adhere to the inner wall of the endotracheal tube, and the gradual accumulation may cause tracheal obstruction. Summary of the invention

[0005] The purpose of the present invention is to provide an endotracheal tube with an anti-dislocation tooth pad in order to solve the above-mentioned problems and overcome the defects of the prior art, as described in detail below.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] The present invention provides an endotracheal tube with an anti-dislocation tooth pad, comprising an endotracheal tube for connecting a ventilator to oxygen, a guide wire being placed inside the endotracheal tube, and a supporting mechanism being arranged outside the endotracheal tube for supporting the endotracheal tube;

[0008] The head of the tracheal tube is provided with a sputum clearing mechanism for sucking sputum;

[0009] The supporting mechanism includes two bite pads, which are respectively attached to the two sides of the endotracheal tube. The two bite pads are fixedly connected to brackets at the positions outside the oral cavity, and one of the brackets is provided with a plug hole, and the other bracket is fixedly connected with a plug rod for inserting into the plug hole for fixing. The two groups of brackets are fixedly connected with fixing belts, and the fixing belts are provided with pin buckles for connection.

[0010] Preferably, the outside of the dental pad is wrapped with a rubber sleeve, and a depression for embedding teeth is provided on the surface of the dental pad, and rounded corners are made on the edges and corners of the dental pad.

[0011] Preferably, the sputum clearing mechanism comprises a plurality of negative pressure airways, wherein the plurality of negative pressure airways are provided on the tracheal tube, wherein the tracheal tube is provided with a plurality of humidified airways, wherein the humidified airways and the negative pressure airways are arranged in an alternating manner, and the humidified airways and the negative pressure airways at corresponding positions are connected through an arc-shaped cavity, and the arc-shaped cavity is connected to the interior of the tracheal tube through a negative pressure port.

[0012] Preferably, the top of the humidified airway is fixedly connected to a humidified air tube via a ventilation ring for receiving the gas humidified by the humidification tank, and the top of the negative pressure airway is fixedly connected to a negative pressure air tube via a ventilation ring.

[0013] Preferably, the sputum clearing mechanism also includes a collecting tank, which is fixedly connected to the negative pressure air pipe, the top of the collecting tank is fixedly connected to an exhaust pipe, the inner wall of the exhaust pipe is fixedly connected to an exhaust fan, and the top of the collecting tank is fixedly connected to a hook.

[0014] Preferably, a partition is fixedly connected to the inner wall of the collecting tank to separate the internal space of the collecting tank. The space on one side of the negative pressure trachea is used to collect sputum, and the space on the side of the exhaust pipe is used to store disinfectant. The partition is fixedly connected to a downward air pipe that connects the spaces on both sides of the collecting tank.

[0015] Preferably, the collecting tank is slidably connected to a suction box on one side of the negative pressure trachea for collecting sputum, and an observation window for observing the liquid level in the space on both sides of the collecting tank is provided on the collecting tank.

[0016] Preferably, the collecting tank is fixedly connected to a partition plate at a position below the space on one side of the exhaust pipe, and the downward air pipe extends to below the partition plate, and the collecting tank is fixedly connected to a waterproof breathable membrane at a position above the space on one side of the exhaust pipe.

[0017] Preferably, an airbag is fixedly sleeved on the outer wall of the tracheal tube near the head, a pressurized tube is fixedly connected to the top of the tracheal tube, and a pressurized airway is opened on the inner wall of the tracheal tube for connecting the pressurized tube and the airbag.

[0018] Preferably, the end of the pressurizing tube away from the endotracheal tube is fixedly connected to a gas injection joint, and a one-way valve is provided inside the gas injection joint. A pressure indicating balloon is fixedly connected to the position of the pressurizing tube near the gas injection joint.

[0019] The beneficial effects are:

[0020] First, the present invention adopts the mode of using two groups of bite pads to fit on both sides of the endotracheal tube for coordinated use, so as to provide good support for the endotracheal tube, effectively prevent the patient from biting the endotracheal tube, avoid deformation or blockage of the tube due to pressure, and ensure the unobstructed airway. When the two groups of bite pads are fitted on both sides of the endotracheal tube, a certain clamping force is also generated to fix the position of the bite pads on the endotracheal tube. The mode of using the two groups of bite pads in coordination makes the force on the gums more dispersed and balanced, which can improve the comfort of the patient wearing the device. The mode of using a fixing belt around the patient's head and fixing it with a pin buckle can be coordinated and fixed. The bite pad and the fixing belt can fix the endotracheal tube firmly in the patient's mouth to prevent the endotracheal tube from shifting or falling out, avoiding the conventional operation of fixing it on the patient's face with tape. After long-term use, the tape may fall off due to the decrease in viscosity caused by the secretions on the patient's face, making it easy for the endotracheal tube to slip out of the airway, causing the patient to have poor ventilation.

[0021] 2. The present invention adopts the method of combining suction through the negative pressure airway with injection of humidified gas through the humidified airway, so that the humidified gas is sucked into the negative pressure airway through the arc cavity. Since the gas flow rate of the arc cavity is faster than the air flow inside the tracheal tube, a slight suction force is generated at the negative pressure port, so that the sputum produced in the patient's body is sucked by the negative pressure port when it enters the position of the head of the tracheal tube. The humidified gas can reduce the viscosity of the patient's sputum and increase the fluidity of the sputum, making it easier to clean, so as to avoid the problem that the patient's sputum adheres to the inner wall of the tracheal tube and gradually accumulates to cause tracheal blockage.

[0022] 3. The present invention can divide the internal space of the collection tank into a sputum collection area and a gas disinfection area by arranging a partition on the inner wall of the collection tank. When the gas enters the sputum collection area of ​​the collection tank through the negative pressure air pipe, the space becomes larger, resulting in a slower flow rate at the position where the negative pressure air pipe outlets the gas. At this time, the sputum carried by the gas in the negative pressure air pipe will drip into the extraction box due to its own gravity, and the gas separated from the sputum will enter the disinfectant in the gas disinfection area through the sinking air pipe for disinfection, so as to avoid the discharge of harmful substances in the gas and polluting the surrounding environment. After the gas in the sinking air pipe enters the disinfectant, bubbles will be formed. During the rising process of the bubbles, they will be divided into smaller and denser bubbles by the dividing plate and evenly distributed in the disinfectant, which can effectively increase the contact area between the gas and the disinfectant, and slow down the floating speed of the bubbles to a certain extent, increase the contact time between the gas and the disinfectant, thereby improving the disinfection and purification effect.

[0023] 4. According to the present invention, after the tracheal tube is correctly inserted into the designated position, the syringe can be inserted into the gas injection joint and a certain amount of gas can be injected. The gas is injected into the air bag through the pressurized tube and the pressurized airway. After the air bag is inflated, it fits tightly with the human tracheal wall, and a closed space can be formed between the tracheal tube and the human tracheal wall to prevent gas leakage from around the tracheal tube, ensure the positive pressure ventilation effect during mechanical ventilation, ensure sufficient gas volume and oxygen supply, effectively prevent the tracheal tube from sliding up and down or moving left and right in the airway, ensure the stability of the intubation position, ensure the ventilation effect, and evenly distribute the pressure around the human tracheal wall to avoid compressive damage to the airway mucosa caused by excessive local pressure.

DETAILED DESCRIPTION

[0034] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0035] See also Figure 1 - Figure 8As shown, the present invention provides an endotracheal tube with an anti-detachment tooth pad, comprising an endotracheal tube 1 for connecting a ventilator to oxygen, a guide wire 12 is placed inside the endotracheal tube 1, a supporting mechanism is arranged outside the endotracheal tube 1 for supporting the endotracheal tube 1, a sputum clearing mechanism is arranged at the head of the endotracheal tube 1 for sucking sputum, wherein the supporting mechanism comprises two tooth pads 2, the two tooth pads 2 are respectively attached to the two sides of the endotracheal tube 1, the two tooth pads 2 are fixedly connected to brackets 3 at the positions outside the oral cavity, and one of the brackets 3 is provided with a plug hole 5, and the other bracket 3 is fixedly connected with a plug rod 6 for inserting into the plug hole 5 for fixing, the two groups of brackets 3 are fixedly connected with fixing belts 4, and the fixing belts 4 are provided with pin buckles for connection, by setting the pin buckles, the fixing belts 4 can be fixed according to the size of the patient's head circumference by adjusting the length of the fixing belt 4, the outside of the tooth pads 2 is wrapped with a rubber sleeve, and The surface of the tooth pad 2 is provided with a depression for embedding teeth, and the corners of the tooth pad 2 are rounded to improve the wearing comfort of the patient. By using two sets of tooth pads 2 to fit on both sides of the endotracheal tube 1 for use in combination, the endotracheal tube 1 can be provided with good support, which can effectively prevent the patient from biting the endotracheal tube 1, avoid the tube from being compressed, deformed or blocked, and ensure the airway is unobstructed. When the two sets of tooth pads 2 are fitted on both sides of the endotracheal tube 1, a certain clamping force will be generated to fix the position of the tooth pad 2 on the endotracheal tube 1. The two sets of tooth pads 2 are used in combination, so that the force on the gums will be more dispersed and balanced, which can improve the wearing comfort of the patient. The fixing belt 4 is used to surround the patient's head and is fixed by a pin buckle, so that coordinated fixation can be performed. The tooth pad 2 and the fixing belt 4 can firmly fix the endotracheal tube 1 in the patient's mouth to prevent the endotracheal tube 1 from shifting or falling out.

[0036] In this embodiment, please refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7The sputum clearing mechanism includes a plurality of negative pressure airways 15, and the plurality of negative pressure airways 15 are provided on the tracheal tube 1. The tracheal tube 1 is provided with a plurality of humidification airways 18, and the humidification airways 18 and the negative pressure airways 15 are arranged in a staggered manner, and the humidification airways 18 and the negative pressure airways 15 at corresponding positions are connected through the arc cavity 13, so that the humidification airways 18 and the negative pressure airways 15 form a relatively independent gas flow path, which can effectively reduce the influence on the internal airflow of the tracheal tube 1, and the arc cavity 13 is connected with the inside of the tracheal tube 1 through the negative pressure port 14, and the negative pressure port 14 is used to inhale sputum adhering to the inside of the endotracheal tube 1, the top of the humidified airway 18 is fixedly connected to the humidified airway 19 through the ventilation ring 16, which is used to access the gas humidified by the humidification tank. The humidified gas injected by the ventilator can reduce the viscosity of the sputum and increase the viscosity and fluidity of the sputum, making the sputum easier to absorb. The top of the negative pressure airway 15 is fixedly connected to the negative pressure airway 17 through the ventilation ring 16. The sputum clearing mechanism also includes a collecting tank 20, which is fixedly connected to the negative pressure airway 17, and the top of the collecting tank 20 is fixedly connected to The exhaust pipe 21 is fixedly connected to the inner wall of the exhaust pipe 21 with an exhaust fan 22, and the top of the collection tank 20 is fixedly connected with a hook 28, so that the collection tank 20 can be hung on the bedside or on an infusion stand. By arranging the exhaust fan 22 at the position of the exhaust pipe 21 to blow air to the outside of the exhaust pipe 21, a negative pressure is generated inside the collection tank 20, so that a negative pressure is also generated inside the negative pressure airway 15 connected to the negative pressure airway 17, and the ventilator injects humidified gas into the humidified airway 18 through the humidified airway 19, so that the pressure in the humidified airway 18 increases, forcing the humidified airway 18 to be ventilated. The humidified gas enters the arc-shaped cavity 13 and is sucked into the negative pressure airway 15. Since the gas flow rate of the arc-shaped cavity 13 is faster than the air flow inside the tracheal tube 1, a slight suction force is generated at the negative pressure port 14, so that the sputum produced in the patient's body is sucked by the negative pressure port 14 when it enters the head of the tracheal tube 1. The humidified gas reduces the viscosity of the patient's sputum and increases the fluidity of the sputum, making it easier to clean, so as to avoid the problem that the patient's sputum adheres to the inner wall of the tracheal tube 1 and gradually accumulates to cause tracheal obstruction.

[0037] For further information, see Figure 7The inner wall of the collecting tank 20 is fixedly connected with a partition 23 for dividing the internal space of the collecting tank 20. The space on one side of the negative pressure air pipe 17 is used to collect sputum, and the space on the side of the exhaust pipe 21 is used to store disinfectant for disinfecting the gas discharged from the patient's body to avoid pollution of the surrounding environment. The partition 23 is fixedly connected with a sinking air pipe 24 for connecting the spaces on both sides of the collecting tank 20. The air intake position of the sinking air pipe 24 is higher than the exhaust position of the negative pressure air pipe 17, which can effectively prevent sputum from mixing into the disinfectant through the sinking air pipe 24 and causing contamination of the disinfectant. The space on one side of the collecting tank 20 in the negative pressure air pipe 17 is slidably connected with a pumping box 25 for collecting sputum. The collecting tank 20 is provided with Observation windows are provided for observing the liquid levels in the spaces on both sides of the collecting tank 20, which facilitates observing the liquid storage conditions in the spaces on both sides of the collecting tank 20. By arranging a partition 23 on the inner wall of the collecting tank 20, the internal space of the collecting tank 20 can be divided into a sputum collection area and a gas disinfection area. When the gas enters the sputum collection area of ​​the collecting tank 20 through the negative pressure air pipe 17, the flow rate at the outlet of the negative pressure air pipe 17 becomes slower due to the increase in space. At this time, the sputum carried by the gas in the negative pressure air pipe 17 will drip into the extraction box 25 due to its own gravity, and the gas separated from the sputum will enter the disinfectant in the gas disinfection area through the sinking air pipe 24 for disinfection, so as to avoid the discharge of harmful substances in the gas and polluting the surrounding environment.

[0038] For further information, see Figure 7 The collecting tank 20 is fixedly connected with a dividing plate 26 at a position below the space on one side of the exhaust pipe 21, and the sinking air pipe 24 extends to the bottom of the dividing plate 26. The collecting tank 20 is fixedly connected with a waterproof breathable membrane 27 at a position above the space on one side of the exhaust pipe 21. The gas in the sinking air pipe 24 will form bubbles after entering the disinfectant. During the rising process of the bubbles, they will be divided into smaller and denser bubbles by the dividing plate 26 and evenly distributed in the disinfectant, which can effectively increase the contact area between the gas and the disinfectant, and to a certain extent slow down the floating speed of the bubbles, increase the contact time between the gas and the disinfectant, thereby improving the disinfection and purification effect. After the bubbles burst, before the gas is discharged from the exhaust pipe 21, the waterproof breathable membrane 27 will also filter and intercept the droplets carried in the gas to prevent the droplets of the disinfectant from being discharged along with the airflow.

[0039] Also, see Figure 1 , Figure 3 , Figure 4 , Figure 6An air bag 10 is fixedly sleeved on the outer wall of the tracheal tube 1 near the head, a pressurizing tube 7 is fixedly connected to the top of the tracheal tube 1, a pressurizing airway 11 is opened on the inner wall of the tracheal tube 1, which is used to connect the pressurizing tube 7 and the air bag 10, and an injection joint 9 is fixedly connected to the end of the pressurizing tube 7 away from the tracheal tube 1, and a one-way valve is arranged inside the injection joint 9 to prevent gas backflow, and a pressure indicating balloon 8 is fixedly connected to the position of the pressurizing tube 7 near the injection joint 9 to display the pressure inside the air bag 10. After the tracheal tube 1 is correctly inserted into the designated position, the syringe can be inserted into the injection joint 9. A certain amount of gas is injected, and the gas is injected into the airbag 10 through the pressurized tube 7 and the pressurized airway 11. After the airbag 10 is inflated, it fits tightly against the human tracheal wall, and can form a closed space between the tracheal tube 1 and the human tracheal wall, preventing gas from leaking from around the tracheal tube 1, ensuring the positive pressure ventilation effect during mechanical ventilation, ensuring sufficient gas volume and oxygen supply, and effectively preventing the tracheal tube 1 from sliding up and down or moving left and right in the airway, ensuring the stability of the intubation position, ensuring the ventilation effect, and evenly distributing the pressure around the human tracheal wall, avoiding excessive local pressure from causing compressive damage to the airway mucosa.

[0040] How it works

[0041] When in use, it is necessary to adjust the patient's position, place the patient in a supine position, tilt the head back, and make the axis of the mouth, pharynx, and larynx as straight as possible, which is helpful to expose the glottis and insert the endotracheal tube 1. First, slowly advance the laryngoscope and push the tongue to the left to fully expose the epiglottis and glottis, and then insert the endotracheal tube 1 shaped by the guide wire 12. When inserting the endotracheal tube 1, accurately align the tube with the glottis. When the head of the endotracheal tube 1 passes through the glottis, there will be a slight sense of disappearance of resistance. At the same time, white mist can be seen in the endotracheal tube 1, which indicates that the endotracheal tube 1 has entered the trachea. Immediately confirm the position. After the endotracheal tube 1 is correctly inserted into the designated position, the syringe can be inserted into the gas injection connector 9 and a certain amount of gas can be injected. The gas is injected into the gas through the pressurized tube 7 and the pressurized airway 11. In the airbag 10, after the airbag 10 is inflated, it fits tightly with the human tracheal wall, and a closed space can be formed between the tracheal tube 1 and the human tracheal wall to prevent gas leakage from around the tracheal tube 1. Then, the two bite pads 2 are slowly pushed into the oral cavity until the teeth are located in the depressions of the bite pads 2, and the two bite pads 2 are respectively fitted on both sides of the tracheal tube 1, so that the plug rods 6 on the bite pads 2 are inserted into the corresponding positions of the plug holes 5 for fixation. According to the size of the patient's head circumference, the length of the fixing belt 4 is adjusted, and the fixing belt 4 is wrapped around the patient's head and fixed by a pin buckle, which can play a role of coordinated fixation. The bite pad 2 and the fixing belt 4 can firmly fix the tracheal tube 1 in the patient's oral cavity to prevent the tracheal tube 1 from shifting or falling out. When facing patients with a lot of sputum, When the ventilator is in the state of being ventilated, an exhaust fan 22 is arranged at the position of the exhaust pipe 21 to blow air to the outside of the exhaust pipe 21, so that negative pressure is generated inside the collection tank 20, and negative pressure is also generated inside the negative pressure airway 15 connected to the negative pressure airway 17, and the ventilator injects humidified gas into the humidified airway 18 through the humidified airway 19, so that the pressure in the humidified airway 18 increases, and the humidified gas is forced to enter the arc-shaped cavity 13 and be sucked into the negative pressure airway 15. Since the gas flow rate of the arc-shaped cavity 13 is faster than the air flow inside the tracheal tube 1, a slight suction force is generated at the negative pressure port 14, so that the sputum produced in the patient's body is sucked by the negative pressure port 14 when it enters the position of the head of the tracheal tube 1, and the humidified gas can reduce the viscosity of the patient's sputum, increase the fluidity of the sputum, and make it The sputum collecting area 22 is easier to clean. By setting a partition 23 on the inner wall of the collecting tank 20, the internal space of the collecting tank 20 can be divided into a sputum collecting area and a gas disinfection area. When the gas enters the sputum collecting area of ​​the collecting tank 20 through the negative pressure air pipe 17, the flow rate at the outlet of the negative pressure air pipe 17 becomes slower due to the larger space. At this time, the sputum carried by the gas in the negative pressure air pipe 17 will drip into the suction box 25 due to its own gravity, and the gas separated from the sputum will enter the disinfectant in the gas disinfection area through the sinking air pipe 24 for disinfection. The gas in the sinking air pipe 24 will form bubbles after entering the disinfectant. During the rising process of the bubbles, they will be divided into smaller and denser bubbles by the dividing plate 26 and evenly distributed in the disinfectant, which can effectively increase the contact area between the gas and the disinfectant.It also slows down the speed of bubbles rising to a certain extent, increases the contact time between gas and disinfectant, and thus improves the disinfection and purification effect. After the bubbles burst, before the gas is discharged from the exhaust pipe 21, the waterproof breathable membrane 27 will also filter and intercept the droplets carried in the gas to prevent the droplets of disinfectant from being discharged along with the airflow.

[0042] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
