The traditional tracheal intubation operation is performed with the assistance of a traditional laryngoscope, the patient lies flat and the head is tilted back, the operator uses external force applied by the traditional laryngoscope to lift the patient's "epiglottis-larynx", the operator observes the exposed glottis through the patient's mouth with the naked eye and sends the tracheal catheter into the patient's trachea. This operation has a small field of view, is inconvenient to operate and requires the operator to have rich operating experience. This operation method can cause damage to the patient's larynx.

[0003] And the existing respiratory tract mirror is generally of a whole structure, in order to clean and disinfect, the rear-end camera part cannot be subjected to high-temperature disinfection, so as to prolong the service life, thus a split structure is needed, and the existing split structure is generally inconvenient to disassemble and assemble, and cannot guarantee the cooperation of the optical fiber and the light source.

[0026] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0027] Example 1, as Figures 1 to 8As shown, a portable visual ventilator includes a display device 1 and a handle 2. The display device 1 includes a display 101 and a connecting device. The connecting device includes a connecting housing 102. The display 101 is movably connected to the connecting housing 102 via a fixed shaft. A mounting groove 103 is formed on the lower surface of the connecting housing 102. A terminal post 104 is fixedly installed in the middle of the inner surface of the mounting groove 103. First wiring through holes 111 are evenly formed on the lower surface of the terminal post 104. A positioning hole 105 is formed in the middle of the terminal post 104. The positioning hole 105 is fixed inside. A light source 106 is fixedly installed. A control switch 107 is installed in the middle of the upper surface of the connecting housing 102. The control switch 107 is connected to the light source 106 via a signal. A stepped surface 108 is provided on the inner surface of the mounting groove 103. A retaining ring 109 is fixedly installed on the stepped surface 108. A button 110 is movably connected to the outer surface of the connecting housing 102. A reset spring 113 is provided between the button 110 and the side surface of the retaining ring 109. A limit ring 112 is movably connected to the bottom of the mounting groove 103. The side surface of the limit ring 112 is fixedly connected to the button 110.

[0028] A connector 201 is fixedly installed at the end of the handle 2. A groove 202 is provided on the end face of the connector 201. A second wiring through hole 203 is evenly opened on the inner surface of the groove 202. The first wiring through hole 112 matches the second wiring through hole 203. A positioning post 204 is fixedly installed in the middle of the inner surface of the groove 202. An optical fiber mounting hole 205 is opened in the middle of the positioning post 204. The end position of the optical fiber mounting hole 205 corresponds to the light source 106. An annular limiting groove 215 is provided on the outer surface of the connector 201. The limiting ring 112 matches the annular limiting groove 215. A connecting tube 207 is provided at the end of the handle 2 away from the connector 201. The connecting tube 207 is assembled and fixed to the insertion tube 208 through a connector assembly. An optical fiber 209 is fixedly installed inside the insertion tube 208. A camera assembly is installed at the end of the insertion tube 208. The upper end of the optical fiber 209 is fixedly installed in the optical fiber mounting hole 205. The wiring contact inside the handle 2 is fixedly installed in the second wiring through hole 203.

[0029] During installation, align the mounting slot 103 below the display device 1 with the connector 201 at the upper end of the handle 2. Press the button 110 to compress the return spring 113, causing the limit ring 112 to move inward. Then, directly install the connector 201 into the mounting slot 103, ensuring that the wiring contacts in the second wiring through hole 203 are connected to the wiring terminals of the display 101 in the first wiring through hole 112. Release the button 110, and the elasticity of the return spring 113 on the inner surface of the button 110 will activate the connection. The limiting ring 112 is moved into the annular limiting groove 215 on the outer surface of the connector 201, thereby achieving the snap-fit ​​and fixation of the connector 1. After fixation, since the upper end of the optical fiber 209 corresponds to the light source 106 inside the positioning hole 105, the operation of the optical fiber 209 can be directly controlled by the control switch 107. Similarly, when disassembling, the button 110 is pressed to move the limiting ring 112 out of the annular limiting groove 215, and then the connector 201 can be taken out from the mounting groove 103.

[0030] In Embodiment 2, as a further improvement to Embodiment 1, the display 101 is a circular display screen. By setting the display 101 as a circular display screen, it is ensured that the edge position of the display 101 corresponds to the imaging circular surface of the camera component.

[0031] In Example 3, as a further improvement to Example 1, a first limiting plane 114 is provided on the inner wall of the positioning hole 105, and a second limiting plane 210 is provided on the outer surface of the positioning post 204. The first limiting plane and the second limiting plane 210 correspond to each other. Through the cooperation of the second limiting plane 210 and the first limiting plane 114, the degree of freedom of rotation of the connector 201 can be limited, thereby further ensuring that the wiring contacts in the second wiring through hole 203 and the wiring terminals in the first wiring through hole 112 can be quickly connected.

[0032] In Example 4, as a further improvement to Example 1, the surface of the limiting ring 112 near the outer side of the mounting groove 103 is provided with a first guide slope, and the end side surface of the connector 201 is provided with a second guide slope, with the first guide slope matching the second guide slope. Thus, when connecting the handle 2 and the display device 1, the matching of the first and second guide slopes allows the connector 201 to be inserted into the mounting groove 103 and fixed by the limiting ring 112 without pressing the button 110.

[0033] In Example 5, as a further improvement to Example 1, the button 110 is provided with a first latch 115 and a second latch 116, and a latching block 117 is provided on the side surface of the limiting ring 112. The first latch 115 is connected and fixed to the latching block 117, and the latching end of the second latch 116 is in movable contact with the inner wall of the mounting groove 103. Through the latching action of the first latch 115 and the latching block 117, the limiting ring 112 is fixed to the button 110 and is also easy to separate during maintenance. The second latch 116 is used to limit the button 15. At the same time, in this example, the latching end of the second latch 116 is a certain distance from the inner surface of the button 110 to ensure that the button 110 has one degree of freedom in the translational direction.

[0034] In Example 6, as a further improvement to Example 1, a turntable 211 is provided inside the handle 2. The turntable 211 is rotatably connected to the inner wall of the handle 2 via a rotating shaft 212. One end of the rotating shaft 212 passes through the inner wall of the handle 2 and is fixedly mounted with an adjusting plate 213. The other end of the rotating shaft 212 is assembled and fixed to a winding wheel 214. Thus, by controlling the adjusting plate 213, the winding wheel 214 is rotated circumferentially to wind and unwind the wire, thereby adjusting the angle of the camera component to facilitate image acquisition.

[0035] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
