Specific embodiment
By the technology contents of detailed the utility model, structure feature, reach purpose and efficacy, below with reference to specification
Attached drawing is described in detail.
As shown in Figure 1, the utility model provides a kind of Rigid bronchoscope protective device, it mainly include ladder cylinder 1, negative pressure group
Part 2, end cap 3 and serum cap 4.Ladder cylinder 1 includes cylinder, stepped end 11 and straight tube end 12, and 1 cylinder of ladder cylinder is hollow tubular
Structure, vertical with the upper short cylinder 21 of negative pressure component 2 to be connected, internal duct communicates.The stepped end 11 of ladder cylinder 1 is stepped, packet
The port minor diameter D1 111 and the port major diameter D2 112 are included, stepped end 11 is connected with the attraction interface tube 51 of Rigid bronchoscope 5, such as
Shown in Fig. 3, it can match with various types of Rigid bronchoscopes.Preferably, stepped end 11 and attraction interface tube 51 can pass through rubber
Sebific duct is connected, and 11 surface of stepped end is trapezoidal thread shape, and sealing effect is good.The straight tube end 12 of ladder cylinder 1 is connect with end cap 3, end
Lid 3 is generally closed state, can inwardly be overturn by external force, and end cap 3 is multi-disc sector elastic slice, is bisected into two layers inside and outside, it is preferable that
Every layer of fan-shaped elastic slice quantity is 2 or 3.It is set as shown in Fig. 2, internal layer sector elastic slice 32 is opposite with internal layer sector 34 same layers of elastic slice
