[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments of the present application. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0025] Please refer to Figure 1 and Figure 2 As shown in the drawings, a sputum suction tube measuring instrument includes a body 100, the body 100 is provided with a control part 110 and a measuring part 130. The measuring part 130 includes a plurality of light sources 131 and a circuit board 133, the plurality of light sources 131 are arranged at intervals along the length direction of the circuit board 133, the plurality of light sources 131 are connected in parallel and the spacing between adjacent light sources 131 is the same. In the present embodiment, the light source 131 is a 0201 type lamp bead, the size of which is 1.0*0.5*0.4mm, and the spacing between adjacent two light sources 131 is 1mm. The control part 110 is used for controlling the opening and closing of the light source 131.

[0026] The control part 110 includes a controller, a keying part 111 and a display part. The controller is a PLC, a multi-circuit parallel control program is written in advance, which is prior art. The keying part 111 is an existing keyboard input device, and the display part is an existing display screen. When a medical staff inputs an instruction such as opening, closing and numerical value through the keyboard part, the controller can perform corresponding actions according to the instruction, for example, the medical staff inputs a numerical value 1.2, and the corresponding 13th light source 131 is lit. In the present embodiment, the unit of the input numerical value is cm by default.

[0027] When the medical staff measures the length of the sputum suction tube by using the sputum suction tube measuring instrument, the measuring instrument needs to be turned on by the control part 110, at this time, the first light source 131 at the starting end of the measuring part 130 is lit. Then input the value according to the length of the sputum suction tube needed to enter the respiratory tract, at this time, the second light source 131 is lit, the straight line distance between the first light source 131 and the second light source 131 is the length of the sputum suction tube needed to enter the respiratory tract, the medical staff uses tweezers or other tools to clamp one end of the sputum suction tube in alignment with the first light source 131, and stretches the sputum suction tube along the length direction of the measuring part 130, the second light source 131 corresponds to the position of the sputum suction tube body, which is the critical point of the sputum suction tube entering the respiratory tract. Taking adult shallow sputum suction length 12.5cm and deep sputum suction length 21.2cm as an example, when the medical staff inputs two values, the 126th light source 131 and the 213th light source 131 are lit correspondingly.

[0028] It should be noted that the sputum suction tube measuring instrument provided by the utility model can be powered by an external power supply and a built-in power supply. In the embodiment, the built-in power supply is used for power supply, specifically, a third cavity 101 for installing a power supply is arranged in the body 100, a positive plate and a negative plate are arranged in the third cavity 101, and the positive plate and the negative plate are electrically connected with the control part 110.

A plurality of light transmission holes 107 are arranged on one side wall of the second cavity 106, and the light transmission holes 107 correspond to the light sources 131 one by one. The light emitted by the light source 131 passes through the light transmission hole 107, so that the medical staff can observe conveniently.

[0031] In addition, a partition plate 108 is arranged between adjacent light transmission holes 107, the partition plate 108 is connected with the cavity wall of the second cavity 106, the light source 131 is located between two adjacent partition plates 108, and when the measuring part 130 is installed in place in the second cavity 106, the end of the partition plate 108 away from the cavity wall abuts against the circuit board 133. The partition plate 108 can block the route of the light along the length direction of the circuit board 133, avoid the light transmission holes 107 except the light transmission hole 107 opposite to the lighted light source 131 from being in the lighted state, and thus facilitate the medical staff to judge the critical position of the sputum suction tube.

[0032] Preferably, a frosted plate 109 made of light transmission material is arranged in the light transmission hole 107, and the frosted plate 109 is bonded with the hole wall of the light transmission hole 107. The frosted plate 109 can increase the scattering of the light, so that the light is softer, and thus a more comfortable observation environment is provided.
