Description
Technical field
This utility model belongs to medical instruments field, the special-purpose amnion aspirator of particularly a kind of department of obstetrics and gynecology.
Background technology
When the gynecologist delivers a child the baby,, adopt amnion aspirator that the amniotic fluid adventitia is punctured usually, amniotic fluid is flowed out in order to prevent amniotic embolism.Because existing amnion aspirator is not provided with check valve, can't prevent that amniotic fluid from refluxing, the amniotic fluid of backflow might cause amniotic embolism, to the parturient childbirth deleterious impact.
Summary of the invention
The purpose of this utility model provides a kind of special-purpose amnion aspirator of department of obstetrics and gynecology of anti-return, can prevent that amniotic fluid from refluxing.
Said purpose realizes through following scheme:
The special-purpose amnion aspirator of a kind of department of obstetrics and gynecology of anti-return; The special-purpose amnion aspirator of described department of obstetrics and gynecology comprises suction tube, protecting tube, push-pull bar and a plurality of syringe needle, and the front end of suction tube is a blind end, and the rear end of suction tube is an opening end; The blind end of suction tube is provided with and the corresponding to suction of syringe needle quantity connectivity port; Each sucks syringe needle of fixed installation on the connectivity port, and an end of the blind end of suction tube and protecting tube is connected to one, and the front end of push-pull bar places in the suction tube through the opening end of suction tube; The front end of push-pull bar is fixed with rubber stopper; Push-pull bar and rubber stopper and suction tube are airtight and be slidingly connected, and the rear end of push-pull bar is provided with push-pull handle, and each sucks in connectivity port and is provided with check valve.
This utility model is simple in structure, easy to use, faces dish or uses during high-order rupture of membranes the puerpera, and the protecting tube of the special-purpose amnion aspirator front end of department of obstetrics and gynecology of the anti-return of this utility model is contacted with fetal membrane; The pumpback push-pull bar makes fetal membrane to be sucked in the protecting tube the interior negative pressure that forms of protecting tube; And through syringe needle fetal membrane is punctured, amniotic fluid flows out into to suction tube then, owing in the suction connectivity port of suction tube, check valve is set; In the process of pumpback, can not make amniotic fluid reflux because of maloperation, effusive speed of amniotic fluid and pressure can artificially be controlled; Amniotic embolism can be effectively prevented to the puerpera, injury can be do not produced the baby.
Description of drawings
Fig. 1 is a kind of front view of this utility model.
Among the figure, suction tube 1, protecting tube 2, syringe needle 3, suction connectivity port 4, push-pull bar 5, rubber stopper 6, push-pull handle 7, check valve 8.
The specific embodiment
As shown in Figure 1, the special-purpose amnion aspirator of a kind of department of obstetrics and gynecology of anti-return, the special-purpose amnion aspirator of described department of obstetrics and gynecology comprises suction tube 1, protecting tube 2, push-pull bar 5 and a plurality of syringe needle 3; The front end of suction tube 1 is a blind end; The rear end of suction tube 1 is an opening end, and the blind end of suction tube 1 is provided with and the corresponding to suction of syringe needle 3 quantity connectivity port 4, and each sucks syringe needle 3 of fixed installation on the connectivity port 4; One end of the blind end of suction tube 1 and protecting tube 2 is connected to one; The front end of push-pull bar 5 places in the suction tube 1 through the opening end of suction tube 1, and the front end of push-pull bar 5 is fixed with rubber stopper 6, and push-pull bar 5 and rubber stopper 6 and suction tube 1 are airtight and be slidingly connected; The rear end of push-pull bar 5 is provided with push-pull handle 7, and each sucks in the connectivity port 4 and is provided with check valve 8.Other member except that syringe needle 3, rubber stopper 6 and check valve 8
Material all the material with existing syringe is identical, adopt medical plastic to be processed into, be convenient to the color that the doctor observes amniotic fluid, judge whether amniotic fluid normal.
