Abstract

The utility model relates to a medical flushing and sucking apparatus head, which can be used for abdominal operations. The utility model comprises an outer sucking and filtering tube whose inside is embedded with an inner sucking and guiding tube, wherein, the handle end of the outer sucking and filtering tube is provided with the other flushing tube and a pressure regulating hole communicated with the outer sucking and filtering tube. The utility model has the advantages of simple structure, convenient operation, little blocking, convenient cleaning, operation time saving, pollution reduction, etc. As flushing liquor is drawn in and a negative pressure sucking apparatus is connected, patient's abdomen can be conveniently flushed, and pus and blood and polluted liquor can be sucked out.

Description

Medical flushing aspirator head

This utility model relates to the flushing aspirator head that a kind of surgical operation medical apparatus and instruments, particularly abdominal operation are used.

In the prior art, as No. 94240656.7, Chinese patent disclosed " disposable use suction aspirator tip ", it is provided with suction pipe, handle, and handle rear end is provided with a union joint, the adjustment hole in hole is inhaled at the connection center that also radially is provided with on the handle, and it can adjust the negative pressure pressure in the suction catheter at any time.No. 93227884.1, Chinese patent disclosed " blockage resisting suction aspirator tip " and for example, negative pressure catheter and outer to attract filter tube be conical pipe in it, and be provided with the interior attraction filter tube of its UNICOM and attract outer negative pressure catheter in the filtration in being fixed at the heavy caliber end of interior negative pressure catheter.The former does not have filtering holes, and the latter does not have adjustment hole, and both all do not have syringe pipe, and the anti-property stopped up is undesirable.

Being of the purpose of this utility model provides medical flushing aspirator head a kind of not only flushable but also that can attract, to overcome the deficiencies in the prior art.

Abdominal operation flushing aspirator head according to this purpose design, comprise outer filter tube and the insertion interior negative pressure catheter wherein of attracting, the outer surperficial uniform filtering holes that attracts the filter tube blind end, its architectural feature are that the outer handle end of filter tube that attracts is provided with another syringe pipe and the regulator hole that communicates with it.Interior negative pressure catheter one end is provided with a joint gradual change extra heavy pipe footpath, so as with the outer tube sleeve fixed bit.

The utlity model has simple in structure, easy to operate, be difficult for to stop up, be convenient to advantage such as cleaning.When syringe pipe insert flushing liquor, vacuum extractor tap in during negative pressure catheter, can wash patient's abdominal cavity easily, the sucking-off purulent blood contaminated fluid.Both operating time can be saved, pollution can be reduced again.

Details are as follows below in conjunction with accompanying drawing embodiment:

Fig. 1 is this utility model one example structure sketch map;

Fig. 2 is Fig. 1 structure and cleaning liquid bottle and vacuum extractor connection diagram.

Referring to accompanying drawing, regulator hole 1 that attracts the handle end of filter tube 3 to be provided with outward to communicate with it and Y-shaped syringe pipe 2, the uniform filtering holes 4 in other end surface, the length L of its fillter section is the 1/2-1/4 of whole pipe range.One end of interior negative pressure catheter 5 is provided with a joint gradual change extra heavy pipe footpath 6, so that overlap fixed bit with outer tube 3 ends.When syringe pipe 2 insert cleaning liquid bottles 7, vacuum extractor 8 tap in during negative pressure catheter 5, just can operate.Push down or decontrol regulator hole 1 with finger, promptly scalable negative pressure pressure prevents to stop up.Present embodiment attracts filter tube 3 to be about 21cm outward, diameter 1.5cm.

Material of the present utility model is metal materials such as non-toxic plastic or stainless steel tube.Its profile also can be Taper Pipe shape or straight tube-like.

Claims
