Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an anti-pollution tool for endotracheal intubation. Background Art

[0002] Tracheal intubation is an airway control technique that inserts a tracheal tube into the trachea through the oral or nasal cavity, which also causes the loss of the defense function of the laryngopharynx. During the intubation operation, the tracheal tube must pass through the oral and nasopharyngeal cavity, and the secretions in the oral and nasal cavities contain a large number of microorganisms. When the tracheal tube passes through the oral and nasal cavities, it will be contaminated with secretions and bring pathogens into the trachea, which can easily cause lung infection after tracheal intubation.

[0003] Currently, oral hygiene is usually cleaned before intubation, and then a drug coating is prepared on the surface of the tracheal tube to inhibit bacterial growth to prevent lung infection after tracheal intubation. However, the above method not only easily enhances bacterial resistance to antibiotics, but also fails to isolate pollutants in the oral cavity.

[0004] Therefore, in view of the above technical problems, a tracheal intubation anti-pollution tool is proposed. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model proposes an endotracheal intubation anti-contamination tool, which can isolate pollutants in the oral cavity, while continuously protecting the endotracheal tube, and avoid the microbial aerosol in the respiratory tract being discharged through the endotracheal tube during the endotracheal intubation operation to infect the operator.

[0006] An anti-contamination tool for endotracheal intubation comprises an endotracheal tube and a protection component, wherein the protection component comprises:

[0007] The intubation guide rail has an open notch portion formed on its circumference; and

[0008] The protective cover has a first port and a second port opposite to each other. The protective cover can be detachably placed in the intubation guide rail through the notch. One end of the tracheal tube can be inserted into the protective cover through the first port. The second port can be folded toward the inside of the protective cover so that the second port is inserted into the tracheal tube and seals the tracheal tube.

[0009] The beneficial effects of the above-mentioned endotracheal intubation anti-contamination tool are:

[0010] During oral intubation, the endotracheal tube and the protective cover are driven into the oral cavity and positioned in front of the glottis by moving the intubation guide rail. The intubation guide rail can prevent the protective cover from directly contacting the oral cavity structure during the process of the protective cover entering the oral cavity and reaching the glottis, thereby preventing the second port of the protective cover from coming out. At the same time, the second port seals the endotracheal tube, thereby preventing the microbial aerosol in the respiratory tract from being discharged through the endotracheal tube and causing infection to the operator. Then, force is applied to the endotracheal tube to advance the endotracheal tube, and the advancement of the endotracheal tube can resist the second port folded in the endotracheal tube, so that the second port The protective cover is gradually turned out from the tracheal tube. When the second port is completely turned out, the tracheal tube can move forward to extend the protective cover and enter the trachea. At this time, the protective cover can isolate the pollutants in the oral cavity outside the protective cover before the tracheal tube enters the trachea, thereby preventing the tracheal tube from bringing pollutants in the oral cavity into the lungs. When the tracheal tube reaches the required intubation depth, the protective cover is moved out of the notch together with the tracheal tube, and then withdrawn from the intubation guide rail. Finally, the tracheal tube is conventionally fixed to complete the intubation operation. At this time, the protective cover is arranged on the tracheal tube to continuously protect the tracheal tube.

[0011] In one embodiment, the inner wall of the protective sleeve is coated with a lubricant. The lubricant coating can reduce the friction between the inner wall of the protective sleeve and the outer wall of the tracheal tube, thereby facilitating the movement of the tracheal tube in the protective sleeve and saving effort in moving the tracheal tube into the trachea.

[0012] In one embodiment, the lubricant is an anesthetic agent. When the tracheal tube moves in the protective sleeve, the anesthetic agent can adhere to the outer wall of the tracheal tube. When the tracheal tube enters the trachea, the anesthetic agent on the outer wall of the tracheal tube can play an anesthetic role, thereby reducing the patient's discomfort when the tracheal tube enters the trachea.

[0013] In one embodiment, a limiting ring is provided at the edge of the first port, and the limiting ring can abut against the end of the intubation guide rail, and one end of the tracheal tube is inserted into the protective cover through the limiting ring. By providing the limiting ring to abut against the end of the intubation guide rail, when the tracheal tube moves forward in the protective cover, the limiting ring can prevent the protective cover from following the tracheal tube forward, thereby facilitating the tracheal tube to extend from the protective cover.

[0014] In one embodiment, it also includes an elastic airbag, on which an interface for air in and out is provided, and the interface can be connected to the other end of the tracheal tube. When the resistance of the tracheal tube against the second port folded in the tracheal tube is large, by pressing the elastic airbag, the gas in the elastic airbag can enter the tracheal tube through the interface and impact the second port folded in the tracheal tube, so that the second port is turned out from the tracheal tube. It is convenient for the second port to be turned out from the tracheal tube, which is convenient for the tracheal tube to extend from the protective cover into the trachea later. At the same time, when the interface is connected to the tracheal tube, the elastic airbag seals the end of the tracheal tube again, improves the sealing effect of the tracheal tube, further avoids the microbial aerosol in the respiratory tract from being discharged through the tracheal tube to cause infection to the operator, and improves the protection effect on the operator.

[0015] In one embodiment, a handle is provided on the peripheral side of the cannula guide rail near the first port. The handle is provided to facilitate the cannula guide rail to move, and the cannula guide rail can be moved conveniently. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0028] See also Figures 1 to 3 In one embodiment, a tracheal intubation anti-contamination tool includes a tracheal tube 10 and a protection component, and the protection component includes an intubation guide rail 20 and a protective cover 30.

[0029] An open notch 201 is provided around the intubation guide rail 20. The protective cover 30 has a first port 301 and a second port 302 opposite to each other. The protective cover 30 can be detachably placed in the intubation guide rail 20 through the notch 201. One end of the tracheal tube 10 can be inserted into the protective cover 30 through the first port 301. The second port 302 can be folded toward the inside of the protective cover 30 so that the second port 302 is inserted into the tracheal tube 10 and the tracheal tube 10 is sealed.

[0030] In the above embodiment, during oral intubation, the endotracheal tube 10 and the protective cover 30 are driven to extend into the oral cavity and be located in front of the glottis by moving the intubation guide rail 20. The intubation guide rail 20 can prevent the protective cover 30 from directly contacting the oral cavity structure during the process of the protective cover 30 entering the oral cavity and reaching the glottis, thereby preventing the second port 302 of the protective cover 30 from coming out. At the same time, the second port 302 seals the endotracheal tube 10, thereby preventing the microbial aerosol in the respiratory tract from being discharged through the endotracheal tube 10 and causing infection to the operator. Then, force is applied to the endotracheal tube 10 to advance the endotracheal tube 10, and the endotracheal tube 10 can advance to collide with the second port 302 folded in the endotracheal tube 10, so that the second port 302 can be closed. The second port 302 is gradually turned out from the tracheal tube 10. When the second port 302 is completely turned out, the tracheal tube 10 can move forward to extend the protective cover 30 and enter the trachea. At this time, the protective cover 30 can isolate the pollutants in the oral cavity outside the protective cover 30 before the tracheal tube 10 enters the trachea, thereby preventing the tracheal tube 10 from bringing the pollutants in the oral cavity into the lungs. When the tracheal tube 10 reaches the required intubation depth, the protective cover 30 and the tracheal tube 10 are moved out of the notch 201, and then the intubation guide rail 20 is withdrawn. Finally, the tracheal tube 10 is conventionally fixed to complete the intubation operation. At this time, the protective cover 30 is sleeved on the tracheal tube 10 to continuously protect the tracheal tube 10.

[0031] On the basis of the above embodiment, further, a lubricant is coated on the inner wall of the protective sleeve 30. Specifically, the lubricant is an anesthetic preparation. By coating the lubricant made of the anesthetic preparation on the inner wall of the protective sleeve 30, it can not only reduce the friction between the inner wall of the protective sleeve 30 and the outer wall of the tracheal tube 10, which is convenient for the tracheal tube 10 to move in the protective sleeve 30, and saves effort when moving the tracheal tube 10 into the trachea, but also can adhere to the outer wall of the tracheal tube 10 when the tracheal tube 10 moves in the protective sleeve 30, so as to play an anesthetic role when the tracheal tube 10 enters the trachea, thereby reducing the discomfort of the patient when the tracheal tube 10 enters the trachea.

[0032] See also Figure 1 , Figure 2 In one embodiment, a limiting ring 3011 is provided at the edge of the first port 301, and the limiting ring 3011 can abut against the end of the intubation guide rail 20, and one end of the tracheal tube 10 is inserted into the protective cover 30 through the limiting ring 3011. By setting the limiting ring 3011 to abut against the end of the intubation guide rail 20, when the tracheal tube 10 moves forward in the protective cover 30, the limiting ring 3011 can prevent the protective cover 30 from moving forward with the tracheal tube 10, thereby facilitating the tracheal tube 10 to extend out of the protective cover 30.

[0033] See also Figure 1 , Figure 2 In one embodiment, an elastic airbag 40 is further included, and an interface for gas in and out is provided on the elastic airbag 40, and the interface can be connected with the other end of the tracheal tube 10. When the resistance of the tracheal tube 10 against the second port 302 folded in the tracheal tube 10 is large, the elastic airbag 40 is pressed to allow the gas in the elastic airbag 40 to enter the tracheal tube 10 through the interface, and the gas entering the tracheal tube 10 can impact the second port 302 folded in the tracheal tube 10, so that the second port 302 is turned out from the tracheal tube 10, and the second port 302 is convenient to turn out from the tracheal tube 10, so that the tracheal tube 10 is subsequently extended from the protective cover 30 into the trachea. At the same time, when the interface is connected with the tracheal tube 10, the elastic airbag 40 seals the end of the tracheal tube 10 again, thereby improving the sealing effect of the tracheal tube 10, further preventing the microbial aerosol in the respiratory tract from being discharged through the tracheal tube 10 to infect the operator, and improving the protection effect of the operator.

[0034] See also Figure 1 , Figure 2 In one embodiment, a handle 202 is provided on the peripheral side of the cannula guide rail 20 near the first port 301. The handle 202 is provided to facilitate the cannula guide rail 20 to move, and the cannula guide rail 20 is convenient to move.

[0035] On the basis of the above embodiment, further, a visualization component is further provided on the handle 202, and the visualization component includes a display 501, a video camera 502 and a power supply 50, the display 501 is provided at the end of the handle 202 away from the intubation guide rail 20, the video camera 502 is provided at the end of the handle 202 close to the second port 302, the video camera 502 is communicatively connected with the display 501, and the power supply 50 is provided on the handle 202, and is electrically connected with the display 501 and the video camera 502. It can be understood that by providing the visualization component, during intubation, the video camera 502 and the display 501 are started by turning on the power supply 50, and when the video camera 502 is extended into the oral cavity, the operator can observe the oral cavity through the display 501, so as to facilitate the movement of the tracheal tube 10 and the protective cover 30 to the front of the glottis by moving the intubation guide rail 20.

[0036] On the basis of the above embodiment, further, a tongue lifting piece 60 extending out of the intubation guide rail 20 is provided at the end of the handle 202 near the second port 302. It can be understood that by providing the tongue lifting piece 60, during intubation, the tongue lifting piece 60 can lift the tongue so that the operator can clearly see the laryngeal structure, such as the vocal cords, epiglottis, laryngeal chamber, etc., and can also reduce the obstruction of the tongue, so that the tracheal tube 10 can enter the trachea more easily.

[0037] The specific implementation of the above-mentioned endotracheal intubation anti-contamination tool is as follows:

[0038] During installation, firstly, the protective cover 30 is placed in the intubation guide rail 20 through the notch 201, and the limiting ring 3011 is abutted against the end of the intubation guide rail 20, then one end of the tracheal tube 10 is passed through the limiting ring 3011 and inserted into the protective cover 30, and finally, a clamping tool (not shown) is used to clamp the second port 302, and then the second port 302 is folded toward the inside of the protective cover 30 by moving the clamping tool, so that the second port 302 is inserted into the tracheal tube 10, and the tracheal tube 10 is sealed to complete the installation.

[0039] During oral intubation, first, the power supply 50 is turned on by holding the handle 202 to start the video camera 502 and the display 501, and then the handle 202 is moved to drive the intubation guide rail 20 to extend into the oral cavity. At this time, the operator can observe the oral cavity through the display 501, so that the tracheal tube 10 and the protective cover 30 can be moved to the front of the glottis by moving the intubation guide rail 20, and the tongue can be lifted by the tongue lifter 60. The operator can clearly see the laryngeal structure and reduce the obstruction of the tongue, so that the subsequent tracheal tube 10 can enter the trachea more easily. At the same time, in the process of the protective cover 30 entering the oral cavity and reaching the glottis, the intubation guide rail 20 can prevent the protective cover 30 from directly contacting the oral cavity structure, thereby avoiding the situation where the second port 302 of the protective cover 30 is detached, and the second port 302 seals the tracheal tube 10, thereby preventing the microbial aerosol in the respiratory tract from being discharged through the tracheal tube 10 and causing infection to the operator.

[0040] Then, force is applied to the tracheal tube 10 to move the tracheal tube 10 forward, and the tracheal tube 10 moves forward to hit the second port 302 folded inside the tracheal tube 10, so that the second port 302 is gradually turned out from the tracheal tube 10. When the second port 302 is completely turned out, the tracheal tube 10 moves forward to extend out of the protective cover 30 and enter the trachea. When the resistance of the tracheal tube 10 hitting the second port 302 folded inside the tracheal tube 10 is large, the interface on the elastic airbag 40 is connected to the tracheal tube 10, and then the second port 302 is pressed to release the airbag 40. The elastic airbag 40 allows the gas in the elastic airbag 40 to enter the tracheal tube 10 through the interface. The gas entering the tracheal tube 10 can impact the second port 302 folded in the tracheal tube 10, so that the second port 302 is turned out from the tracheal tube 10. At this time, the tracheal tube 10 can be moved out of the protective cover 30 and enter the trachea. At this time, the protective cover 30 can isolate the pollutants in the oral cavity outside the protective cover 30 before the tracheal tube 10 enters the trachea, thereby preventing the tracheal tube 10 from bringing the pollutants in the oral cavity into the lungs.

[0041] Finally, when the tracheal tube 10 reaches the required intubation depth, the protective cover 30 and the tracheal tube 10 are removed from the notch 201, and then the intubation guide rail 20 is withdrawn, and finally the tracheal tube 10 is conventionally fixed to complete the intubation operation. At this time, the protective cover 30 is placed on the tracheal tube 10 to continuously protect the tracheal tube 10.
