Abstract
The utility model relates to a membrane rupturing drainage device, which adopts a round tube made of medical use plastic. The utility model is characterized in that a doroid shaped membrane touching circulus (1) is arranged at the head of the round tube, an upside down cone shaped membrane rupturing fossa cavity (2) is arranged inside the membrane touching circulus (1), and is connected with a drainage cavity (4), a membrane rupturing pricking needle (3) made of stainless steel is arranged at the front end of the drainage cavity (4), the top end of the membrane rupturing pricking needle (3) is positioned inside the membrane rupturing fossa cavity (2), the top end of the membrane rupturing pricking needle (3) is lower than the lower part of the membrane touching circulus (1), and a tube connector (5) is arranged at the back end of the round tube.
Description
Technical field
This utility model relates to technical field of medical instruments, belongs to obstetrics' apparatus, is a kind of apparatus that is used for artificial rupture of membranes, particularly a kind of rupture of membranes drainage device.
Background technology
The artificial rupture of membrane induced labor is obstetrics' induced labor commonly used method of hastening parturition, and the method for the artificial rupture of membranes of implementing clinically is at present: after the conventional vulvar disinfection, the practise midwifery doctor is with sterile gloves, behind left hand food, middle finger stripping, and amniotic sac before touching.The right hand is held rupture of membranes fork or gynecological's pincers, guides along the food middle finger of left hand to puncture or clip broken fetal membrane.Exist the operation precision relatively poor, easily cause the shortcoming of fetal scalp damage, exist when the rupture of membranes afterwaters flows out to enter the circulation of puerpera's maternal blood along the blood vessel of cervical canal damage, produce the risk of bringing out puerpera's amniotic embolism.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, and rupture of membranes drainage device a kind of simple in structure, easy to use is provided.
The technical solution of the utility model is as follows: the rupture of membranes drainage device, it is the pipe made from medical plastic, it is characterized in that the head of pipe is provided with the zona that touches of semi-annular shape, touch and have inverted cone-shaped rupture of membranes cavity in the zona and communicate with drainage lumens, the front end of drainage lumens is equipped with the rupture of membranes pricker of stainless steel, the top of rupture of membranes pricker is located in the rupture of membranes cavity, and promptly the vertical height of rupture of membranes pricker is lower than the height that touches the zona bottom, and the afterbody of pipe is provided with pipe joint.
This utility model is simple in structure, has advantage easy to use, safe and reliable.But the amniotic fluid of drain simultaneously reduces the risk that amniotic embolism takes place the puerpera.

The specific embodiment
The rupture of membranes drainage device, it is the pipe made from medical plastic, it is characterized in that: what the head of pipe was provided with semi-annular shape touches zona (1), touch and have inverted cone-shaped rupture of membranes cavity (2) in the zona (1) and communicate with drainage lumens (4), the front end of drainage lumens (4) is equipped with the rupture of membranes pricker (3) of stainless steel, the top of rupture of membranes pricker (3) is located in the rupture of membranes cavity (2), and promptly the vertical height of rupture of membranes pricker (3) is lower than the height that touches zona (1) bottom, and the afterbody of pipe is provided with pipe joint (5).
During use, this utility model multipara vagina enters cervix uteri, after touching zona (1) and touching fetal membrane, pipe joint (5) connects depression drainage device by flexible pipe, starts depression drainage device, makes drainage lumens (4) be negative pressure state, the suction fetal membrane enters rupture of membranes cavity (2), fine rotation this utility model, rupture of membranes pricker (3) punctures fetal membrane, and amniotic fluid is drawn out of along drainage lumens (4).
Claims (1)
1, rupture of membranes drainage device, it is the pipe made from medical plastic, it is characterized in that: what the head of pipe was provided with semi-annular shape touches zona (1), touch and have inverted cone-shaped rupture of membranes cavity (2) in the zona (1) and communicate with drainage lumens (4), the front end of drainage lumens (4) is equipped with the rupture of membranes pricker (3) of stainless steel, the top of rupture of membranes pricker (3) is located in the rupture of membranes cavity (2), and promptly the vertical height of rupture of membranes pricker (3) is lower than the height that touches zona (1) bottom, and the afterbody of pipe is provided with pipe joint (5).
