Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the A portion enlarged diagram of Fig. 1 of the present invention.
In figure: 1 puncture sheath pipe, 2 ventilation sacculus, 3 perforator sacculus, 4 perforator inner cores, 5 ventilation interfaces, 6 valve lobes, 7 silica gel sealing sets, 8 pipelines, 9 airtight tablettings, 10 be tightly connected set, manage in 11,12 outer tubes.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is specifically described.
Fig. 1 show the structural representation of the present invention.
The present invention includes puncturing sheath pipe 1, ventilation sacculus 2 and perforator inner core 4.
The front end of described puncture sheath pipe 1 is provided with perforator sacculus 3.
Described perforator sacculus 3 is oval, kidney shape or circle.
It is 300-1500ml that described perforator sacculus 3 can hold gas flow.
Described puncture sheath pipe 1 rear end is provided with ventilation interface 5, and described ventilation interface 5 is connected with ventilation sacculus 2 by pipeline 8.
Fig. 2 show the A portion enlarged diagram of Fig. 1 of the present invention.
The tail end of described puncture sheath pipe 1 is double-decker, including interior pipe 11 and outer tube 12.
Interior pipe 11 end of described puncture sheath pipe 1 is provided with valve lobe 6, is sequentially provided be tightly connected set 10 and silica gel sealing set 7, it is prevented that gas leakage, it is achieved the reverse circulation of closed for second time gas outside valve lobe 6.
Outer tube 12 tail end of described puncture sheath pipe 1 is provided with airtight tabletting 9, and valve lobe 6, silica gel sealing set 7 and airtight adapter sleeve 10 are fixed in perforator inner core 4 by described airtight tabletting 9, it is achieved prevent gas leakage and back flow of gas.
Shown perforator inner core 4 end is smooth passivity structure, and its size is longer than puncture sheath pipe 1, and perforator inner core 4 inserts from the rear end valve lobe 6 puncturing sheath pipe 1 and punctures in sheath pipe 1, and its front end is stretched in perforator sacculus 3.
