Abstract
An artificial membrane rupturing needle for a puerpera is characterized in that a needle sleeve is arranged outside the artificial membrane rupturing needle; and a needle head inside the artificial membrane rupturing needle is connected with a pusher through a spring. During artificial membrane rupture by the conventional method, the exposed needle head easily punctures hands of a doctor and injuries vagina and cervix of the puerpera accidentally to cause bleeding and infection of the puerperal and the doctor; and in order to avoid the problems and better protect the doctor and the puerpera, the artificial membrane rupturing needle is provided. When the artificial membrane rupturing needle is used, a thumb presses the pusher, the needle head pops out of the needle sleeve to rupture a fetal membrane, the thumb presses the pusher again, and the needle head retracts into the needle sleeve. Therefore, the artificial membrane rupture is easy, convenient and safe to operate.
Description
Technical field
This utility model relates to medical instruments field, and a kind of artificial rupture of membrane pin is used for puerpera's artificial rupture of membrane specifically, to understand amniotic fluid shape, induced labor, acceleration stages of labor.
Background technology
The traditional method of present artificial rupture of membrane: after hands is worn sterile gloves, hand-held needle enters vagina, cervix uteri, punctures fetal membrane, be exposed to outer syringe needle and easily stab doctor's hands, puerpera's vagina or cervix uteri, cause puerpera and doctor's hemorrhage, infection even cause some haematogenous infectious disease.For avoiding above problem, better protection doctor and puerpera have invented a kind of artificial rupture of membrane pin.
The utility model content
This utility model when solving puerpera's artificial rupture of membrane, with the operated in accordance with conventional methods inconvenience, dangerous, problem, invented a kind of artificial rupture of membrane pin.
The technical solution of the utility model is, a kind of artificial rupture of membrane pin, its special character be, needle guard is arranged outward, and syringe needle connects pusher by spring in it.Can effectively protect puerpera and doctor during artificial rupture of membrane, avoid stabbing, prevent hemorrhagely, prevent that the haematogenous infectious disease from taking place.
During use, vaginal speculum exposes cervix uteri behind the routine disinfection birth canal, and hand-held artificial rupture of membrane pin is sent into vagina, when the needle guard head end touches fetal membrane, thumb press pusher, syringe needle namely eject from needle guard, puncture fetal membrane, and amniotic fluid flows out, thumb is pressed pusher again, in the syringe needle withdrawal needle guard, withdraws from vagina.Make simple, convenient, the safety of artificial rupture of membrane.
Description of drawings
Fig. 1 is that structure of the present utility model is watched figure attentively, and the accompanying drawing that makes an abstract.
In Fig. 1,1. needle guard 2. syringe needles 3. springs 4. pushers.
The specific embodiment
Below in conjunction with drawings and Examples, this utility model is further specified.
As shown in Figure 1: in needle guard 1, have syringe needle 2 to connect pusher 4 by spring 3.
During use, vaginal speculum exposes cervix uteri behind the routine disinfection birth canal, hand-held artificial rupture of membrane pin is sent into vagina, when needle guard 1 head end touches fetal membrane, and thumb press pusher 4, syringe needle 2 namely ejects from needle guard 1 by spring 3, puncture fetal membrane, amniotic fluid flows out, and thumb is pressed pusher 4 again, in the syringe needle 2 withdrawal needle guards 1, withdraw from vagina.Make simple, convenient, the safety of artificial rupture of membrane.
At present existing 300 many cases puerperas are with artificial rupture of membrane pin of the present utility model, all effectively, artificial rupture of membrane safely, do not infect, hemorrhage situation, have obtained the effect of being satisfied with, and are worthy to be popularized clinically, use.
