In order to facilitate the understanding of the disposable visible tracheal intubation kit provided by the embodiment of the present application, its application scenario is firstly explained below. To improve the difficulty of intubation, the embodiment of the present application provides a disposable visible endotracheal intubation kit, which will be described in detail below with reference to the accompanying drawings.

Referring first to FIG. 1 , FIG. 1 shows a schematic structural diagram of a disposable visible endotracheal intubation kit provided by an embodiment of the present application. The disposable visible tracheal intubation set firstly includes a handle 10, which is elongated and has a certain curvature. When the handle 10 is specifically set, it conforms to ergonomics and is convenient for doctors to hold. One end of the handle 10 is detachable (the specific detachable method can adopt the existing clamping or threaded connection, etc.) connected to a pipeline, the pipeline is provided with a working channel, and the set working channel includes a plurality of side-by-side One end of the dedicated oxygen supply channel is connected to the working channel interface, and the other end of the standard interface can be connected to the Y-type connector of the anesthesia ventilator. In addition, the end of the handle 10 away from the pipeline is provided with a signal interface 11 .

The pipeline is divided into two parts during specific arrangement, which are respectively named rigid pipeline 20 and flexible pipeline 30 for the convenience of description, and the rigid pipeline 20 and the flexible pipeline 30 are connected. When setting up the pipeline, the rigid pipeline 20 is detachably fixedly connected to the handle 10 . And the flexible pipe 30 communicates with the end of the rigid pipe 20 away from the handle 10 . As shown in FIG. 2 , the rigid pipeline 20 includes an inner tube 22 and a PE medical grade catheter 21 wrapped around the inner tube 22 . And the inner tube 22 is a 304 stainless steel capillary. Stainless steel is annealed to make it flexible and easy to shape. Alternatively, an aluminum core, a copper hose or a serpentine tube can be used, so that the tube body can be molded while maintaining a certain strength. In addition, the outer sheath of the stainless steel capillary is PE medical grade catheter 21 . In specific setting, the wall thickness of the inner tube 22 is 0.2mm-0.6mm, such as 0.2mm, 0.4mm, 0.6mm and other thicknesses. The outer diameter of the rigid pipe 20 is 2.5mm-6mm. To adapt to endotracheal tubes of different sizes. In addition, when setting the length of the rigid pipe 20, it can be 30cm-45cm, such as 30cm, 35cm, 40cm, 45cm and so on. In addition, the inner tube 22 is marked with a scale for prompting the placement position of the rigid pipe 20 .

Continuing to refer to FIG. 1 , a balloon 40 is fitted on the rigid pipe 20 , and the balloon 40 is located at the end of the rigid pipe 20 away from the handle 10 . The balloon 40 is used to inflate after insertion to stretch the trachea, and to deflate the balloon 40 when the pipeline is pulled out so that the pipeline can be pulled out conveniently. Therefore, when the balloon 40 is set, the balloon 40 is required. It has good elasticity and avoids sticking to the trachea. For this reason, the balloon 40 provided by the embodiment of the present application adopts the balloon 40 made of TPU material. The TPU material has outstanding physical and mechanical properties. In addition, it has good compatibility, which is beneficial to protect the airway mucosa and avoid damage to the airway. In addition, after the balloon is deflated, the balloon can be completely attached to the tube wall, making extubation smoother. Of course, the balloon 40 can also be a balloon made of silica gel or PVC.

When the balloon 40 is specifically arranged, as shown in FIG. 3 , the balloon 40 adopts a double-layer balloon body. Specifically, the balloon 40 includes a nested first balloon body 41 and a second balloon body 42, wherein , the first balloon body 41 is located outside the second balloon body 42, and the material of the first balloon body 41 is made of the above-mentioned TPU material, so as to improve the effect of sticking to the trachea. In addition, a sensor for detecting the air pressure in the first bag body 41 is arranged on the second bag body 42, the situation of the air pressure in the second bag body 42 can be detected by the sensor provided, the pressure in the balloon body can be observed in real time, and the air pressure in the bag body can be improved. Effect of balloon support.

When in use, the trachea where the end of the flexible tube 30 is located can be stretched by the balloon 40 , so as to facilitate the flow of oxygen or medicinal liquid input by the flexible tube 30 .

Continuing to refer to FIG. 1 , when specifically setting the flexible tube 30 , the flexible tube 30 is located outside the balloon 40 , and the flexible tube can be bent as required. A camera assembly is disposed inside the flexible pipe 30 , the camera assembly is located at an end of the flexible pipe 30 , and the camera assembly is at least partially located at an end of the flexible pipe 30 away from the balloon 40 .

As shown in FIG. 4 and FIG. 5 , wherein FIG. 4 shows a schematic structural view of the part where the camera assembly is located in the flexible pipe, and FIG. 5 shows a schematic view of the end face of this part. The part of the camera assembly located in the flexible pipe includes: a sleeve 51 fixed in the flexible pipe 30 , the sleeve 51 has a certain strength, and the length direction of the sleeve 51 is arranged along the length direction of the flexible pipe 30 . In addition, the end of the sleeve 51 facing the end of the flexible pipe is sealed with a lens 52 ; wherein, a camera 55 is fixed inside the sleeve 51 , and the camera 55 is sealingly connected with the sleeve 51 . When setting the camera 55 specifically, the lens of the camera 55 faces the lens 52, and a foam 56 is arranged between the lens 52 and the lens; in addition, a plurality of LED lights 54 are arranged around the lens on the camera 55. When the above-mentioned structure is adopted, the lens package is in the form of sleeve 51 + lens 52 + foam 56 + camera 55 . The sleeve 51 is used to fix the lens 52 , as shown in FIG. 4 , a black aperture 53 is printed on the lens 52 . In addition, the foam 56 is fixed on the front of the lens to isolate the LED light 54 from the lens. During assembly simultaneously, the foam 56 withstands the black aperture 53 on the lens 52 to prevent light spots from appearing. Adopting this packaging method of the camera 55 avoids using glue to package the lens, and can greatly shorten the packaging time of the camera 55 without affecting the image quality.

In order to improve the shooting effect, the camera assembly 50 adopts a digital camera assembly, and at least three LED lights 54 are arranged around the periphery of the digital camera assembly 50, and the LED lights 54 are cold light sources. When in use, the trachea is irradiated by an LED light to improve the image collection effect of the camera assembly 50 . For example, in a specific embodiment, the use of 6 LED lights can ensure that the camera assembly 50 has sufficient illumination in the airway environment; and through processing, the heat generation of the camera assembly 50 can be effectively controlled within 35 degrees to reduce the temperature of the camera assembly 50. Protect the patient's airway to the greatest extent. And the diameter of the camera assembly 50 is set to be between 3.0 mm and 6.0 mm, such as 3 mm, 3.9 mm, 4.5 mm and other different sizes for endotracheal tubes of different specifications. In addition, the pixel of the camera component 50 is 1 million imaging pixels, which has a good imaging effect.

As shown in FIG. 6 , the camera component provided by the embodiment of the present application further includes a chip 57 , which may specifically be an image digital processing chip (DSP). Wherein, the chip 57 is connected with the camera 55 . During specific setting, the chip 57 is located in the handle 10, and the camera 55 communicates with the image digital processing chip through a data line. Among them, the camera 55 itself adopts a mipi camera. The DSP is arranged in the handle 10, and the signal interface 11 connected to the DSP adopts a Type-C port as an image transmission signal interface. It can be seen from FIG. 3 that after the DSP is installed in the rear, only the camera 55 and its accessories are included in the flexible pipe 30, so the inflexible part arranged in the flexible pipe 30 can be effectively shortened and the bendable radius can be reduced. It is convenient for shaping, and at the same time, the temperature of the tip of the camera 55 is well controlled. In addition, the data transmission of the 10-pin pin port of the Type-C port can effectively solve the problem of data transmission.

In addition, when the camera assembly is specifically set up, it also includes a rigid guide wire threaded in the pipeline, and a camera assembly (a component of the camera assembly located in the flexible pipeline) that is rotatably connected to the rigid guide wire. The camera assembly is defined by a rigid guide wire, and the camera assembly can rotate relative to the rigid guide wire. And the kit provided by the embodiment of the present application further includes an adjusting device connected with the camera assembly and used to adjust the rotation angle of the camera assembly. In a specific setting, the adjusting device includes: a driving device connected with the rigid guide wire, a transmission device passing through the rigid guide wire, and the transmission device is connected with the camera assembly (the camera assembly is located in the flexible pipe). Wherein, the specific transmission device includes that the driving device includes a first synchronous wheel that is rotatably connected with the rigid guide wire; Timing belt on the second timing pulley. The driving device can be a turntable that rotates with the first synchronous wheel. By rotating the turntable, the first synchronous wheel is driven to rotate. The first synchronous wheel drives the second synchronous wheel to rotate through the synchronous belt, and then drives the camera 55 to rotate. The above-mentioned drive is relatively common synchronous drive structure, so it will not be repeated here. Of course, the above-mentioned adjusting device can also use other known methods to drive the camera head 55 to rotate. I won't go into details here.

As shown in FIG. 7 , in order to directly observe the shooting effect, the disposable visible endotracheal intubation kit also includes a display device detachably connected to the camera assembly through a data cable during setting. Therefore, the shooting effect can be directly observed through the display device. During specific connection, the display device includes a display screen 60 , and the display screen is connected to the signal interface 11 of the camera assembly 50 through a data line 70 . In order to ensure the stability of the connection, the end provided on the data line 70 is provided with a buckle, that is, when connecting, the end is first connected to the display screen 60, and then the port and the display screen 60 are fixed by the buckle. In this way, the force on the terminal is reduced, and the terminal and the display screen 60 are fixed by buckles, thereby improving the stability of data transmission. When displaying, the imaging is very clear through the use of brand-new digital imaging technology. And through the data line 70, a large screen can be connected, and the resolution is guaranteed to a large extent, which is conducive to teaching and training of related knowledge and skills, and the display device has a two-hour power reserve, so it is more secure to use.

When setting up the display device, the display device also includes a bracket that is rotatably connected with the display screen 60 and can be locked at a set position. When specifically set, the bracket is a telescopic bracket, and its specific structure may include a first telescopic tube and a second telescopic tube nested in the first telescopic tube, and the first telescopic tube and the second telescopic tube are connected by a lock The locking screw is locked and fixed, and the locking screw is a relatively common locking method, which will not be described in detail here. In addition, when the display screen 60 is locked with the second telescopic tube, it can also be locked by locking screws.

In addition, the rigid tube and the flexible tube in the disposable endotracheal tube kit are disposable tubes, so as to completely prevent the risk of cross-infection.

At present, the intubation tools on the market for matching with disposable endotracheal tubes include red light sticks and intubation guide wires. The biggest advantage of the optical rod is that it directly exposes the glottis, which greatly improves the success rate of intubation under visual conditions. At present, there are various types of light sticks for visible endotracheal intubation on the market, but they are basically reused because of the high cost. It is therefore of great advantage to have the cheapest placement of the camera in the endotracheal tube using a low-cost solution.

Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these modifications and variations.
