The specific embodiment
With the following Examples this utility model is further described.
A kind of from aerofluxus Anti-bubble dropping funnel, as shown in Figure 1 to Figure 3, be provided with body 100, input pipe 200, exhaust apparatus, dosing end 500 and pumping equipment.
The structure setting of protuberance 130, in infusion process, how no matter dropping funnel placed can normally be carried liquid, easy to use and flexible.
Need to prove, also can dosing end 500 be set according to practical situation.
Concrete, exhaust apparatus is provided with exhaust end 320 and exhaustor 310, and exhaust end 320 fixedly is assemblied in upper end cover 110, and exhaustor 310 is fixedly connected with upper end cover 110, and exhaustor 310 is communicated with exhaust end 320.
The part that input pipe 200 inserts upper end covers 110 is length H, length H less than exhaustor 310 apart from the distance B between upper end cover 110.When infusing, the liquid of outside medicated bag is connected with input pipe 200, and siphunculus input pipe 200 splashes in dropping funnel, and medical personnel observe the speed of dripping of liquid by input pipe 200 usually.Apart from the distance B between upper end cover 110, the gas in dropping funnel will can be lower than exhaustor 310 ends like this less than exhaustor 310 for the length H that input pipe 200 inserts upper end covers 110, and the liquid level in dropping funnel can be higher than exhaustor 310 ends yet.Like this, just can effectively observe the speed of dripping of input pipe 200 ends.
Pumping equipment is arranged at body 100 inside and pumping equipment and the fixing assembling of bottom end cover 120.
Pumping equipment is provided with outlet tube 410, and outlet tube 410 is provided with inlet opening 420, and inlet opening 420 is arranged at the upper end of outlet tube 410.
Usually, inlet opening 420 is set to more than two usually, as five, seven.Also can be set to as required an inlet opening 420.
Pumping equipment also is provided with assembling stand 430, and outlet tube 410 passes assembling stand 430 and is fixedly connected with assembling stand 430, and assembling stand 430 fixedly is assemblied in bottom end cover 120.
Assembling stand 430 lower surfaces are provided with filtration membrane 440, and filtration membrane 440 is assemblied between assembling stand 430 and bottom end cover 120.The aperture of filtration membrane 440 is not more than 5 microns, can accurately filter the granule more than 5 microns, and good filtration effect can effectively prevent particle contamination.
In infusion process, the liquid in body 100 enters outlet tube 410 by inlet opening 420, is discharged by bottom end cover 120 after diaphragm 440 filters after filtration by outlet tube 410.Because apocenosis passage only has inlet opening 420, outlet tube 410, therefore liquid can only be discharged by this passage.
The setting of exhaust apparatus, pumping equipment, no matter which kind of state dropping funnel is in, and air all can not enter downcomer, can prevent that gas from passing through outlet tube 410 and discharging, guarantee that in infusion process, gas enters vein blood vessel, can guarantee infusion safety, avoid the blood back phenomenon to occur.
In addition, of the present utility model also have characteristics simple in structure, that cost is low, easy to use from aerofluxus Anti-bubble dropping funnel.
Should be noted that at last; above embodiment only is used for the explanation the technical solution of the utility model but not to the restriction of this utility model protection domain; although with reference to preferred embodiment, this utility model has been done detailed description; those of ordinary skill in the art is to be understood that; can modify or be equal to replacement the technical solution of the utility model, and not break away from essence and the scope of technical solutions of the utility model.
