1 to 3 of the drawings show an embodiment of the ventilation connector for an endoscope according to the present invention, and FIG. 1 shows an endoscope equipped with the ventilation connector connected to a control device. An external view when connected,
Fig. 2 shows only the upper half of the air supply connector in the process of being connected to the ventilation connector with two-dot chain lines, and also shows the main part configuration by cutting away only the upper half of the ventilation connector when it is closed and sealed. Figure 3 shows only the upper half of the air supply connector, which can be connected to the ventilation connector to supply air, with a two-dot chain line.
It is a diagram for explaining the configuration of the main part of the ventilation connector with only the upper half thereof cut away when ventilation is possible, and FIGS. 4 to 6 of the drawings show an example of a conventional ventilation connector of an endoscope. Fig. 4 is an external view similar to Fig. 1, and Fig. 5 is an external view of the air supply connector connected to the air supply device immediately before connecting it to the ventilation connector. FIG. 6 is a diagram for explaining the configuration of essential parts, showing only the lower half of both parts cut away, and FIG. 6 is a cross-sectional view of the connected state.
