Detailed implementation manners

[0034] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0035] Embodiment 1

[0036] As Figures 1 to 10 shown, a tracheal intubation includes a tracheal intubation body 100. A spraying unit is installed on the tracheal intubation body 100. The spraying unit includes a spraying mechanism and a protection mechanism. When the tracheal intubation body 100 is pulled out, the spraying unit performs a spraying function through the spraying mechanism, and the protection mechanism is used to protect the spraying mechanism.

[0037] Embodiment 2

[0038] As Figures 1 to 4 shown, in the detailed implementation manner, the spraying unit further includes a manifold chamber 200. The manifold chamber 200 is movably sleeved outside the tracheal intubation body 100. The spraying mechanism includes a nozzle 205. The nozzle 205 is located outside the manifold chamber 200. The protection mechanism includes a closing component. The closing component is used to close the nozzle 205. A delivery pipe 206 is installed on one side of the manifold chamber 200. The delivery pipe 206 is used to deliver medicament. In this setting, the medicament includes an anesthetic, which is used to prevent discomfort in the patient's throat when the tracheal intubation body 100 is pulled out.

[0039] As Figures 1 to 4As shown in the figure, further, the closing component includes an overcurrent chamber 201, which is fixedly installed outside the current collecting chamber 200 and communicates with the current collecting chamber 200. An external ring 202 is fixedly installed outside the overcurrent chamber 201, and a clamping groove 203 is formed on the external ring 202. The closing component further includes a connecting pipe 204, one end of the connecting pipe 204 is connected to the overcurrent chamber 201, and the other end is connected to the spray head 205. One end of the spray head 205 is adapted to the clamping groove 203. In this setting, the end face of the spray head 205 is inclined, so that when the spray head 205 is attached to the clamping groove 203, the axial direction of the spray head 205 itself forms an acute angle with the direction of the side where the clamping groove 203 is attached, so as to better hold the spray head 205.

[0040] The implementation principle of an endotracheal tube in this embodiment is as follows: When spraying is not carried out, the connecting pipe 204 is bent and the spray head 205 is abutted against one side of the clamping groove 203. At this time, the spray head 205 is protected. When the endotracheal tube body 100 needs to be taken out, a spraying operation is required. At this time, a medicament is injected into the delivery pipe 206 through a syringe. The medicament enters the current collecting chamber 200 through the delivery pipe 206 and is delivered to the overcurrent chamber 201. Since the connecting pipe 204 is in a bent state, the flow rate of the bent part is small. Continuously delivering the medicament increases the pressure in the overcurrent chamber 201, so that the bent part is straightened under the action of the pressure. At the same time, the spray head 205 also moves accordingly to be exposed, and the medicament is sprayed out through the spray head 205, thereby achieving the anesthetic effect.

[0041] Embodiment 3

[0042] As Figures 5 to 7 shown, this is another specific implementation manner of an endotracheal tube of the present application.

In this setting, a plurality of nozzles 305 are provided to spray the medicament more evenly.

[0043] As Figures 6 to 7 shown, further, the protection mechanism includes symmetrically arranged protection shells 302, the protection shells 302 are movably sleeved on the installation pipe 300, the protection mechanism further includes a first spring 301, the first spring 301 is movably sleeved on the installation pipe 300, and the elastic force of the first spring 301 acts on the protection shell 302 to make the protection shell 302 seal the nozzle 305. In this setting, the first spring 301 is always in a compressed state, so that the protection shell 302 always protects the nozzle 305.

[0044] As Figure 5 、 Figure 7 、 Figure 8As shown, further, the spray unit also includes an injection unit connected thereto, an air duct 307 and a drug duct 308 are connected between the injection unit and the spray unit, and the injection unit injects air and drugs into the spray unit through the air duct 307 and the drug duct 308.

In this configuration, a detachable connector is installed between the first connecting tube 309 and the air conduit 307, and between the second connecting tube 310 and the drug conduit 308.

[0046] like Figures 7 to 8 As shown, further, an air cushion 303 is installed inside the protective shell 302, a valve 304 is installed on one side of the air cushion 303, the valve 304 is connected to the air duct 307, the first injection mechanism injects air into the air cushion 303 through the valve 304 to expand the air cushion 303, the nozzle 305 is movably connected to the air cushion 303, a connecting pipe 306 is installed at one end of the nozzle 305, and the connecting pipe 306 is connected to the medicine duct 308. In this configuration, after the air cushion 303 expands, the protective shell 302 is opened to expose the nozzle 305.

[0047] like Figures 8 to 10 As shown, further, the first injection mechanism includes a first piston 314, the first piston 314 is slidably sealed and connected in the first chamber 312, a movable groove 315 is provided in the first piston 314, a piston block 317 is movably installed in the movable groove 315, and a second spring 316 is installed between the piston block 317 and the movable groove 315. In this configuration, the piston block 317 and the second spring 316 are adaptively changed after being subjected to air pressure, so as to prevent the air cushion 303 from exploding due to too much air injected by the first injection mechanism.

[0048] like Figures 8 to 10As shown, further, the second injection mechanism includes a second piston 319, which is slidably and sealingly connected in the second chamber 313. A locking assembly is arranged on the second piston 319, and the locking assembly includes an insertion rod 320, which is movably inserted into the second piston 319, and one end of the insertion rod 320 extends to the outside of the injection tube 311, and a guide rod 322 is fixedly installed on the other end of the insertion rod 320.

A third spring 321 is installed inside the second piston 319, and the third spring 321 is fixedly connected to the insertion rod 320. In this configuration, the first piston 314 is moved so that the side wall of the first piston 314 blocks the first connecting pipe 309. At this time, the air cushion 303 remains in an expanded state. While the first piston 314 moves, it drives the guide rod 322 to move through the guide groove 318. The guide rod 322 drives the insertion rod 320 to move so that the second piston 319 can move. At this time, the first piston 314 presses against the second piston 319 and drives it to move. The second piston 319 delivers the medicine to the nozzle 305 through the second connecting pipe 310 and the medicine conduit 308.

[0049] The implementation principle of a tracheal intubation in this embodiment is as follows: when spraying is not performed, the elastic force of the first spring 301 acts on the protective shell 302 to close the protective shell 302 and seal the nozzle 305. When spraying is required, the first piston 314 is pressed, and the elastic force of the third spring 321 pushes the insertion rod 320 to insert into the side wall of the injection tube 311, so that the second piston 319 remains stationary. When the first piston 314 moves, air is transported to the air cushion 303 through the first connecting pipe 309 and the air duct 307. At this time, the air cushion 303 expands and opens the protective shell 302, so that the nozzle 305 is exposed;

[0050] Continue to move the first piston 314 so that the side wall of the first piston 314 blocks the first connecting pipe 309. At this time, the air cushion 303 remains in an expanded state. While the first piston 314 moves, it drives the guide rod 322 to move through the guide groove 318. The guide rod 322 drives the insertion rod 320 to move so that the second piston 319 can move. At this time, the first piston 314 presses against the second piston 319 and drives it to move. The second piston 319 delivers the medicine to the nozzle 305 through the second connecting pipe 310 and the medicine conduit 308.
