Abstract
The utility model relates to the technical field of medical instruments, which belongs to an obstetric instrument, and is an instrument for artificial rupture of fetal membranes, in particular to a membrane breaking flow diverter. The membrane breaking flow diverter substantially is a medical round tubular shell which is made of the plastics, and is characterized in that the head of the round tubular shell is equipped with a semicircle annular membrane touching ring, in which a membrane breaking recessed cavity with conical surfaces which is communicated with a drainage cavity is arranged, the front end of the drainage cavity is equipped with a membrane breaking prod which is made of a stainless steel, the tip of membrane breaking prod is arranged in the membrane breaking recessed cavity, the drainage cavity is communicated with a negative pressure cavity which is arranged on the lower of the drainage cavity, and a piston is arranged in the negative pressure cavity. The utility model has the advantages of simple structure, convenient operation, and safety and reliability, simultaneously, the utility model is capable of draining an amniotic fluid, and reducing the risk of amniotic fluid embolism of lying-in women.
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 a kind of rupture of membranes drainage device simple in structure, easy to use is provided.
The technical solution of the utility model is as follows: a kind of rupture of membranes drainage device, main body is the pipe shape housing that medical plastic is made, it is characterized in that: the head of pipe housing is provided with the zona that touches of semi-annular shape, touch the rupture of membranes cavity that is provided with taper seat 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, and the tip of rupture of membranes pricker is located in the rupture of membranes cavity, drainage lumens communicates with the negative pressure cavity that it is provided with below, and piston is housed in the negative pressure cavity.
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
A kind of rupture of membranes drainage device, main body is the pipe shape housing (6) that medical plastic is made, what the head that it is characterized in that pipe housing (6) was provided with semi-annular shape touches zona (1), touch the rupture of membranes cavity (2) that is provided with taper seat 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 tip of rupture of membranes pricker (3) is located in the rupture of membranes cavity (2), drainage lumens (4) communicates with its negative pressure cavity that is provided with below (5), and piston (7) is housed in the negative pressure cavity (5).
During use, this utility model inserts from vagina, make that its head is provided with touch zona (1) and touch fetal membrane after, outwards twitch piston (7), the interior negative pressure that produces of negative pressure cavity (5) is also passed to negative pressure in the rupture of membranes cavity (2) by drainage lumens (4), rotate 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, main body is the pipe shape housing (6) that medical plastic is made, what the head that it is characterized in that pipe housing (6) was provided with semi-annular shape touches zona (1), touch the rupture of membranes cavity (2) that is provided with taper seat 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 tip of rupture of membranes pricker (3) is located in the rupture of membranes cavity (2), drainage lumens (4) communicates with its negative pressure cavity that is provided with below (5), and piston (7) is housed in the negative pressure cavity (5).0
