Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is structural representations of air bag;
In upper figure: fixing head 1, fixing band 2, hasp 3, positioning needle jacket casing 5, pressurization airbag 6, air bag 7, gas tube 8, gas-charging connection 7.1, gas tube 7.2, sealing top plug 7.3, gas exchange chamber 7.4, pneumatic jack spring 7.5, bag 7.6, convex annular back-up ring 7.7.
The specific embodiment
1-2 by reference to the accompanying drawings, the utility model will be further described:
This utility model comprises fixing head 1, fixing band 2, hasp 3, positioning needle jacket casing 5, pressurization airbag 6, air bag 7, gas tube 8, fixing head 1 is arcuate structure, the two ends of fixing head 1 are connected and fixed is with 2, fixing band 2 connects by hasp 3, the centre of described fixing head 1 is provided with locating hole 4, and the interior stationary positioned syringe cover 5 of described locating hole 4, is provided with pressurization airbag 6 between fixing head 1 and positioning needle jacket casing 5, the gas tube 8 that passes through of described pressurization airbag 6 connects air bag 7, and described air bag 7 comprises gas-charging connection 7.1, gas tube 7.2, sealing top plug 7.3, gas exchange chamber 7.4, pneumatic jack spring 7.5, bag 7.6, convex annular back-up ring 7.7, the inside of gas-charging connection 7.1 is provided with gas tube 7.2, gas-charging connection 7.1 connects bag 7.6 by gas exchange chamber 7.4, the inside in described gas exchange chamber 7.4 is provided with pneumatic jack spring 7.5 and sealing top plug 7.3, sealing top plug 7.3 passes through pneumatic jack spring 7.5 apical graftings in the gas outlet of gas tube 7.2, one end of pneumatic jack spring 7.5 connects sealing top plug 7.3, and the other end of pneumatic jack spring 7.5 is fixed on the convex annular back-up ring 7.7 of bag 7.6 entrances.
Described fixing band 2 is rigid plastics band.
During use, during puncture, stationary positioned syringe cover on fixing head, by transfusion syringe, in air bag, inflate, by the syringe portion of transfusion syringe is stretched into gas tube inside by sealing top plug jack-up, press transfusion syringe the air extrusion of syringe inside is arrived to gas exchange intracavity portion, by airbag, enter pressurization airbag inner, realize inflation, after gassy, the syringe of infusing is extracted out, pneumatic jack spring promotes sealing top plug and gas tube closely cooperates, prevent gas leakage, guarantee the accurate positioning of puncturing, after having punctured, positioning needle jacket casing is extracted out, the air of air bag inside compresses site of puncture, prevent that site of puncture liquid from flowing out, guarantee the healing of site of puncture after puncturing, avoid causing the infection of site of puncture.
The beneficial effects of the utility model are: can realize the healing of the site of puncture after puncture location and puncture simultaneously, can well realize the protection of site of puncture, the liquid outflow that prevents site of puncture causes the damage to wound, improves the healing effect of wound, reduces the secondary injury that patient is caused.
