Description

Pumping device

Technical field

This utility model belongs to medical instruments field, specifically pumping device.

Background technology

In the middle of medical events, sometimes medical personnel need to carry out drawing liquid process in patient body, under normal circumstances, all adopt syringe connecting duct, and then connecting puncture needle carries out drawing liquid in body, but so often consume the very large muscle power of medical personnel could extract, if accidentally overexert landing apparatus, also can cause actual bodily harm to patient.

Utility model content

The pumping device that this utility model provides can facilitate medical personnel to take out patient body fluid.

The technical solution of the utility model is as follows: pumping device, comprise puncture needle, stiff end, silica gel tube and negative pressure bottle, described stiff end has inner chamber, described puncture needle wherein one end is fixedly connected with described stiff end two ends respectively with described silica gel tube, puncture needle described in described inner space and described silica gel tube, the described silica gel tube other end is provided with sharp instrument, described negative pressure bottle is provided with drain end and end of bleeding, described negative pressure bottle is provided with drainage channel, described drainage channel inwall is provided with a circle rubber baffle, and described drainage channel matches with described sharp instrument.

End of bleeding on described negative pressure bottle of the present utility model is for extracting described negative pressure bottle inner air, thus allow described negative pressure bottle produce negative pressure, now described rubber baffle is for stopping that extraneous air enters in described negative pressure bottle, when described puncture needle reaches drawing liquid position through human skin, after described sharp instrument matches with described drainage channel, described rubber baffle is pierced through again by described sharp instrument, thus described silica gel tube is connected with described negative pressure bottle, due to puncture needle described in described inner space and described silica gel tube, negative pressure inside described like this negative pressure bottle will carry out drawing liquid by pressure difference to puncture place, reach the effect of negative pressure drawing liquid, bring convenience to medical personnel, practical.

Further, described drainage channel import is less than described sharp instrument length to the depth of described rubber baffle.

Further, described drain end is connected with the first lid by the first rubber band, and described drain end matches with described first lid.

Further, described in bleed end be connected with the second lid by the second rubber band, described in bleed end match with described second lid.

Further, described silica gel tube outer wall is provided with a circle sucker near described sharp instrument end.

Further, described stiff end outer wall is provided with the groove with radian.

Further, described sharp instrument is from close described silica gel pipe end to more and more less away from described silica gel pipe end internal diameter.
