[0024] As Figure 1 and Figure 2 shown, an auxiliary intubation device 10 includes a guiding block 100 and an intubation assembly 200. The guiding block 100 includes a tongue-depressing portion 110 and a holding portion 120. A sliding groove 111 extending from the tongue-depressing portion 110 to the holding portion 120 is formed on one side surface of the guiding block 100. The intubation assembly 200 includes a flexible tube 210 and a tube-pushing member 220. A clamping block 230 is provided at one end of the flexible tube 210. The flexible tube 210 is embedded in the sliding groove 111 so that the clamping block 230 is located at the end of the holding portion 120 away from the tongue-depressing portion 110. The tube-pushing member 220 is provided on the holding portion 120. The tube-pushing member 220 is used to drive the flexible tube 210 to slide along the sliding groove 111 so that the end of the flexible tube 210 away from the clamping block 230 extends out or retracts from the end of the tongue-depressing portion 110 away from the holding portion 120.

[0025] It should be noted that the tongue depressor part 110 is used to be inserted into the mouth of a patient. The tongue depressor part 110 is designed to have a structure similar to that of a tongue depressor in the prior art, and both are in a curved shape. In this way, it is convenient for medical staff to use the guiding block 100 to apply a certain external force to the root of the tongue by means of the tongue depressor part 110. A chute 111 that changes along the shape of the guiding block 100 is formed on the side wall of the guiding block 100, and the chute 111 extends from the tongue depressor part 110 to the holding part 120. The hose 210 is fittingly embedded in the chute 111. When the hose 210 is embedded in the chute 111, the clamping block 230 located at one end of the hose 210 is on the holding part 120. Further, the tube-pushing part 220 is installed in the holding part 120. The tube-pushing part 220 is used to apply an external force to the clamping block 230 so that the hose 210 can slide along the chute 111. The usage process of the auxiliary intubation device 10 will be described below. When in use, first embed the hose 210 into the chute 111, where the clamping block 230 is in the holding part 120 and the clamping block 230 is connected to the tube-pushing part 220, and the end of the hose 210 away from the clamping block 230 is on the end of the tongue depressor part 110 away from the holding part 120. The medical staff holds the holding part 120, inserts the tongue depressor part 110 into the patient's mouth, uses the tongue depressor part 110 to hook and pull the root of the patient's tongue to lift it by a certain distance, then uses the tube-pushing part 220 to push the clamping block 230 so that the hose 210 slides along the chute 111 to accurately pass through the opened epiglottis, then takes out the hose 210 from the inside of the chute 111, then takes away the guiding block 100, and continues to insert the hose 210 into the patient's body. In this way, rapid and accurate intubation operation is achieved. Compared with the method that requires at least two medical staff in the prior art, the auxiliary intubation device 10 of the present application can be operated by a single person, which is convenient and fast, and effectively improves the intubation success rate and avoids damage to the patient caused by repeated intubation.

[0026] As Figure 1 and Figure 2 shown, in one embodiment, the guiding block 100 further includes a middle connecting part 130. The two ends of the middle connecting part 130 are respectively connected to the tongue depressor part 110 and the holding part 120, and the chute 111 extends from the tongue depressor part 110 through the middle connecting part 130 to the holding part 120.

[0027] It should be noted that the middle connecting part 130 is located between the tongue depressor part 110 and the holding part 120. As a connecting structure between the tongue depressor part 110 and the holding part 120, the middle connecting part 130 can prevent medical staff from directly contacting the tongue depressor part 110. At the same time, when it is convenient for medical staff to insert the tongue depressor part 110 into the patient's mouth, the end of the tongue depressor part 110 can accurately reach the position of the root of the tongue.

[0028] As Figure 1 and Figure 2 shown, in one embodiment, a tube-pressing part 140 is provided on the middle connecting part 130. The tube-pressing part is used to extend into the chute 111 to press the hose 210.

[0029] It should be noted that in order to ensure that the hose 210 can be stably maintained in the chute 111 when it is not driven by the shifting member 220 to slide, a pressing member is provided on the middle connecting portion 130. The pressing member is used to apply a clamping force to the hose 210 so that the hose 210 is clamped and fixed in the chute 111. When the shifting member 220 needs to slide the hose 210 along the chute 111, only the pressing member needs to be loosened.

[0030] As Figure 3 shown, in one embodiment, the pressing member is a pressing rod 141. The pressing rod 141 is screwed to the middle connecting portion 130. When the pressing rod 141 is stressed and rotates, one end of the pressing rod 141 extends into the chute 111 or exits from the chute 111.

[0031] It should be noted that in this embodiment, the pressing member is a pressing rod 141 with a threaded structure. A threaded hole is provided on the middle connecting portion 130. The pressing rod 141 is screwed into the threaded hole. By rotating the pressing rod 141, the end of the pressing rod 141 can extend into the chute 111 or exit from the chute 111. When the end of the pressing rod 141 extends into the chute 111, the end of the pressing rod 141 can press and clamp the hose 210. In one embodiment, an anti-slip layer is provided on one end of the pressing rod 141 close to the chute 111. For example, the anti-slip layer is a silicone coating. In this way, the friction between the pressing rod 141 and the hose 210 can be effectively increased.

[0032] As Figure 4 shown, in one embodiment, the pressing member includes a pressing rod 142 and an elastic member 143. The pressing rod 142 passes through the middle connecting portion 130. The elastic member 143 is respectively in contact with the pressing rod 142 and the middle connecting portion 130. The elastic member 143 is used to push the pressing rod 142 so that once the pressing rod 142 extends into the chute 111.

[0033] It should be noted that in this embodiment, the pressing member is composed of a pressing rod 142 and an elastic member 143. Specifically, a through hole is provided on the middle connecting portion 130. The pressing rod 142 passes through the through hole. The elastic member 143 is respectively in contact with the pressing rod 142 and the middle connecting portion 130. In this way, the elastic thrust of the elastic member 143 is used to push the pressing rod 142 so that one end of the pressing rod 142 extends into the chute 111 to press and clamp the hose 210. In one embodiment, the elastic member 143 is a spring. In this way, the pressing rod 142 is always pushed by the elastic member 143, so that one end of it always extends into the chute 111 to press and clamp the hose 210. When the hose 210 needs to be pulled out from the inside of the chute 111, only the pressing rod 142 needs to be pulled in the opposite direction to compress the elastic member 143.

[0034] In one embodiment, there are two pressing pipe fittings, and the two pressing pipe fittings are respectively located on two opposite sides of the sliding groove 111. In this way, the hose 210 is clamped from two opposite directions, so that the hose 210 is reliably clamped and fixed in the sliding groove 111.

[0035] As Figure 1 shown, in one embodiment, an LED lamp 150 is provided at one end of the pressing tongue portion 110 away from the holding portion 120.

[0036] It should be noted that the LED lamp 150 is located at that end of the pressing tongue portion 110 away from the holding portion 120. In this way, the LED lamp 150 provides light, which is convenient for medical staff to see the intubation position of the patient during intubation.

[0037] As Figure 1 and Figure 2 shown, in one embodiment, an avoidance groove 121 is formed on the holding portion 120. The avoidance groove 121 is communicated with the sliding groove 111, and the clamping block 230 is located in the avoidance groove 121.

[0038] It should be noted that in order to facilitate the pressing pipe fitting 220 to apply an external force to the clamping block 230, the avoidance groove 121 is formed on the holding portion 120, and the clamping block 230 is located in the avoidance groove 121. On the other hand, when the end of the hose 210 located at the pressing tongue portion 110 is driven by the pressing pipe fitting 220 to insert through the epiglottis, the medical staff can conveniently pinch the hose 210 from the avoidance groove 121, so that the hose 210 can be easily pulled out laterally from the sliding groove 111.

[0039] As Figure 1 and Figure 2 shown, in one embodiment, the pressing pipe fitting 220 includes a driving member 221 and a sliding rod 222. The sliding rod 222 is slidably arranged in the holding portion 120 along the extending direction of the sliding groove 111, and one end of the sliding rod 222 extends into the avoidance groove 121 to be detachably connected to the clamping block 230. The driving member 221 is arranged in the holding portion 120, and the driving member 221 is connected to the sliding rod 222. The driving member 221 is used to drive the sliding rod 222 to drive the clamping block 230 to slide in the avoidance groove 121, so that the hose 210 slides along the sliding groove 111.

[0040] It should be noted that a sliding hole is formed in the holding portion 120 along the extending direction of the sliding groove 111. The sliding hole is communicated with the avoidance groove 121, and the sliding rod 222 slides in the sliding hole. In this way, when the clamping block 230 is connected to the sliding rod 222, the driving member 221 can drive the sliding rod 222 to slide, so that the sliding rod 222 drives the clamping block 230 to slide in the avoidance groove 121, and further makes the hose 210 slide along the sliding groove 111.

[0041] As Figure 5As shown, in one embodiment, the driving member 221 is a lever 2211 or a motor. It should be noted that the sliding rod 222 can be manually driven by a human or electrically driven by a motor. Specifically, in one embodiment, when manually driven, one end of the lever is fixedly connected to the sliding rod 222, and the other end of the lever passes through the holding portion 120. By applying an external force to the lever by a medical staff, the sliding rod 222 can be driven to slide within the holding portion 120. In another embodiment, when electrically driven, the output shaft of the motor is screwed to the sliding rod 222. In this way, by pressing the start switch to start the motor, the sliding rod 222 can be driven to slide within the holding portion 120, so that the sliding rod 222 drives the hose 210 to slide within the chute 111 through the clamping block 230, enabling the end of the hose 210 located at the tongue depressor portion 110 to be quickly and stably inserted and passed through the epiglottis of the patient.

[0042] As Figure 6 shown, in one embodiment, the sliding rod 222 includes a connecting block 2221 and two rod arms 2222. The two rod arms 2222 are both slidably disposed within the holding portion 120, and one end of each of the two rod arms 2222 is located within the clearance groove 121. The other ends of the two rod arms 2222 are both connected to the connecting block 2221, and the driving member 221 is connected to the connecting block 2221.

[0043] It should be noted that the driving member 221 drives the two rod arms 2222 to slide synchronously relative to the holding portion 120 through the connecting block 2221. Specifically, when the driving member 221 is a manually operated lever, the lever is directly fixedly connected to the connecting block 2221. When the driving member 221 is an electrically operated motor, the output shaft of the motor is screwed to the connecting block 2221. In this way, the two rod arms 2222 respectively clamp the opposite sides of the clamping block 230, ensuring that the sliding rod 222 can stably drive the hose 210 to slide within the chute 111.

[0044] As Figures 5 to 8 shown, in one embodiment, a folding block 2223 is provided at the end of the rod arm 2222 away from the connecting block 2221, and a clamping groove 22231 is formed within the folding block 2223 for clamping the clamping block 230.

[0045] In this way, by inserting the clamping block 230 into the clamping groove 22231, the folding block 2223 and the clamping block 230 can be reliably fixed. When the clamping block 230 is pulled out from the clamping groove 22231, the clamping block 230 can be separated from the folding block 2223. In this way, the clamping block 230 and the sliding rod 222 are detachably connected.

[0046] As Figure 8 shown, in one embodiment, the auxiliary intubation device 10 further includes an endoscope 300, and the endoscope 300 is inserted through the hose 210.

[0047] It should be noted that the endoscope 300 can be used to examine the inside of a patient's body and can also be used to assist in the auxiliary insertion of the hose 210. Specifically, first insert the endoscope 300 into the hose 210, and then place the hose 210 in the chute 111. During this process, the endoscope 300 is always located inside the hose 210. After placing the hose 210 in the chute 111, snap the clamping block 230 into the clamping groove 22231 for clamping. Then, the medical staff holds the holding portion 120 of the guiding block 100 and inserts the tongue depressor portion 110 into the patient's mouth, and uses the tongue depressor portion 110 to hook and pull the patient's tongue root to lift it a certain distance. During this process, the medical staff can clearly view the specific position of the end of the hose 210 located in the patient's mouth through the endoscope 300. When the medical staff uses the tongue depressor portion 110 to hook and lift the patient's tongue root a certain distance and sees that the patient's epiglottis is pulled open through the endoscope 300, since the endoscope 300 is located inside the hose 210, it means that the hose 210 has been aligned with the open position of the patient's epiglottis. At this time, the medical staff drives the sliding rod 222 to slide through the driving member 221, and the sliding rod 222 pushes against the clamping block 230, causing the hose 210 to slide along the chute 111, so as to smoothly pass through the epiglottis and insert into the patient's body. During this process, the LED lamp 150 installed at the end position of the tongue depressor portion 110 facilitates the medical staff to view the specific position of the hose 210 in the patient through the endoscope 300, further improving the convenience of inserting the hose 210. Finally, after the hose 210 passes through the epiglottis and inserts into the patient's body, the medical staff pinches the hose 210 through the provided clearance groove 121. After loosening the pressing member to release the clamping of the hose 210, the hose 210 is withdrawn laterally from the chute 111. After the hose 210 is separated from the guiding block 100, the remaining part of the hose 210 is continued to be inserted into the patient's body to complete the intubation operation. In this way, compared with the method of using a tongue depressor in cooperation with a trachea in the prior art, the auxiliary intubation device 10 of the present application can be independently operated by one person, that is, the intubation operation can be completed quickly and accurately, not only effectively improving the intubation success rate, but also being convenient and fast for medical staff to operate, and can avoid damaging the patient due to intubation errors.

[0048] As Figure 1 shown, in an embodiment, an indicating airbag 211 is provided on the hose 210, a positioning airbag is provided on the hose 210, and the indicating airbag 211 is communicated with the positioning airbag.

[0049] It should be noted that when the hose 210 is inserted into the patient's body, in order to stably maintain the hose 210 in the inserted position, a positioning airbag is provided on the hose 210. By inflating the positioning airbag to make it expand, the outer wall of the positioning airbag is supported in the patient's body, so that the hose 210 can be stably retained in the patient's body. In order to make the positioning airbag be filled with an appropriate amount of gas, an indicating airbag 211 is provided and communicated with the positioning airbag, which is convenient for medical staff to obtain the accurate air pressure of the positioning airbag through the indicating airbag 211.

[0050] The above embodiments only represent several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. Among them, the installation / fixing / setting mentioned in the present invention can be understood as including but not limited to locking and fixing by using screws / screws, welding unless otherwise specifically defined.
