Detailed description of the invention
Preferred implementation of the present utility model is described in detail below in conjunction with accompanying drawing.
In order to reach the purpose of this utility model, in the some of them embodiment of safe ear washing bulb,
As it is shown in figure 1, safe ear washing bulb includes air bag main body 1 and the connecting tube 2 connected with air bag main body 1, connecting tube 2 is rubber tube. Opening part at air bag main body 1 is provided with air bleeding valve 3. Connecting tube 2 includes: link 21 in T set up of character patt ern, imbibition end 22 and move liquid end 23, and link 21 and imbibition end 22 are arranged on same straight line. Link 22 is connected with air bag main body 1, is provided with filling-valve 4 on link 21. Imbibition end 22 is connected with external pipet or pipette. Moving, liquid end 23 is provided with fluid-delivery valve 5.
Air bleeding valve 3, filling-valve 4 and fluid-delivery valve 5 be not by external force time, in closed mode, after being subject to external force, in opening.
The work process of the safe ear washing bulb of this utility model is as follows:
1) first the imbibition end 22 of connecting tube 2 is connected with pipet.
2) firmly pin air bleeding valve 3, extruding gasbag main body 1, the gas in air bag main body 1 is discharged so that air bag main body 1 is in low-pressure state.
3) pinning filling-valve 4, by pressure difference, liquid is inhaled in pipet, now, liquid can extended stationary periods in pipet.
4) pin fluid-delivery valve 5, due to pressure difference, liquid can be discharged pipet.
Compared with prior art, the having the beneficial effect that of the safe ear washing bulb of this utility model:
Continuous use by air bleeding valve 3, filling-valve 4 and 5 three valves of fluid-delivery valve, ensure that ear washing bulb continuous and stable in imbitition process carries out, and the liquid in pipet can be allowed for a long time to rest on required scale, overcome tradition ear washing bulb that the liquid in pipet cannot be allowed to rest on the drawback of required scale, thus causing certain loss in pipetting processes. Tradition ear washing bulb can be avoided because of misoperation, and the liquid being drawn is inhaled into ear washing bulb air bag, directly contributes the solution being drawn contaminated simultaneously. This utility model device, it is possible to improve the accuracy of experimental implementation, increase substantially conventional efficient.
As in figure 2 it is shown, in order to optimize implementation result of the present utility model further, in other embodiment, all the other feature technologies are identical, are different in that, being provided with air bag 6 in the outside of fluid-delivery valve 5, the opening part moving liquid end 23 is located at by air bag 6.
Adopt the scheme of above-described embodiment, pin fluid-delivery valve 5, due to pressure difference, liquid can be discharged pipet, and utilize air bag 6 to connecting tube 2 air-blowing, more fast and effectively liquid can be removed pipet.
As it is shown on figure 3, in order to optimize implementation result of the present utility model further, in other embodiment, all the other feature technologies are identical, are different in that, the bore of imbibition end 22 is gradually reduced to opening direction.
Adopt the scheme of above-described embodiment, be more convenient for being connected with pipet or pipette.
Novel preferred implementation, it is noted that for the person of ordinary skill of the art, under the premise creating design without departing from this utility model, it is also possible to making some deformation and improvement, these broadly fall into protection domain of the present utility model.
