The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is made a detailed explanation.
Embodiment 1:
A kind of stone sacculus equipment of getting as shown in Figure 1, comprise conduit 5 and the sacculus 6 that is arranged on conduit 5 heads, conduit 5 is connected with syringe 1, be provided with Air Valve Control switch 2 between conduit 5 and the syringe 1, as Fig. 2～shown in Figure 5, described Air Valve Control switch comprises valve body 26 and rotates the rotary valve 21 that is plugged in the valve body 26, valve body 26 is provided with syringe interface 261 that is connected with syringe 1 and the catheter interface 262 that is connected with injection port 3 on the conduit 5 by outer locking joint 25, wherein, 21 hermetic seals are connected described valve body 26 with rotary valve, described rotary valve 21 is provided with first communication passage that only is communicated with syringe interface 261 and catheter interface 262 when switch opens, and this first communication passage is by passage A211, centre bore and passage B212 constitute; Also be provided with the single-way gas-discharge structure on the described valve body 26, this single-way gas-discharge structure comprises spring 22, connecting axle 23 and button 27, connecting axle 23 is plugged in the valve body 26 and can moves axially, connecting axle 23 1 ends offset by spring 22 and rotary valve 21, connecting axle 23 other ends stretch out valve body 26 and affixed with button 27, wherein, be arranged with packing ring 24 on the described connecting axle 23, packing ring 24 cooperates with valve body 26 conical surface of inboard wall, as shown in Figure 4, second communication passage of connecting tube interface 262 and valve body 26 inner spaces only that described rotary valve 21 is provided with switch when closing, this second communication passage is made of passage C213 and centre bore.Wherein, passage A211, passage C213 and passage B212 interval 90 degree angles in same plane.
