Abstract
The utility model discloses a film breaking machine for the obstetrics and gynecology department, which comprises an air pocket, a piston pump, a suction tube, a sucking disk and a puncture needle, wherein the suction tube is thin and long, and integrated with the piston pump; the front end of the suction tube is connected with the bell-mouth-shaped sucking disk; the rear end of the piston pump is connected with the air pocket; the piston pump is internally provided with a piston; one end of the needle body inside the suction tube is fixed on the piston pump; and the sucking disk is provided with a plurality of suction holes communicated with the suction tube. The distance from the piston to the step where the suction tube is connected with the piston pump is equal to the length of the needle body extending out of the plain mouth of the sucking disk, namely the depth for film breaking; as the distance is set before the film breaking machine leaves the factory, when in use, the length of the extended-out needle, namely the depth for film breaking, is determined, thus overcoming the defect that as the depth of the needle can not be controlled better, a common film breaking machine injures a fetus only by experience.
Description
Technical field
This utility model belongs to the clinical assistive device of department of obstetrics and gynecology, especially relates to the membrane-repturing device that a kind of obstetrics' rupture of membranes of active phase uterine inertia is used.
Background technology
In the clinical obstetrics, for the puerpera of active phase uterine inertia and uterine contraction difficulty, generally the method by means of artificial rupture of membrane helps to produce.There are problems in the membrane-repturing device that uses.As the patent No. is 200620160991.0 " a kind of artificial membrane-repturing device ", and the structure of this artificial membrane-repturing device is: be fixed with operating grip on the needle guard guide wire, the rupture of membranes pin passes the needle guard guide wire, and needle handle is fixedlyed connected with the rupture of membranes pin.This membrane-repturing device is rational in infrastructure, Nover practical, but have the problem of function singleness, and promptly only playing the effect of rupture of membranes, the drainage problem behind the rupture of membranes does not solve, and easily causes the amniotic fluid overflow, causes infection.
The patent No. is 200320106862 " multifunction manual membrane-repturing device ", its structure is made of negative pressure cylindrical shell, exhaust tube, end at negative pressure cylindrical shell contact amniotic fluid film is established the bell mouth of covering arcuation, cover is loaded onto transparent elastic film on the lural mouth of covering arcuation, fibre-optic bundle on the lural inboard bonding of covering arcuation, establish cone-shaped funnel in the outer end of negative pressure cylindrical shell, thin layer of glass plate in the oral area shutoff of cone-shaped funnel is established flexible rotating blade in inboard, negative pressure cylindrical shell middle part.Though function is more, solved rupture of membranes and amniotic fluid drainage problem simultaneously, there is complex structure, troublesome poeration, the problem that manufacturing cost is high.
Simultaneously, more than two kinds of membrane-repturing devices only rely on experiential operating, often owing to can accurately not control the degree of depth that syringe needle thrusts, injure fetus, the safety of rupture of membranes is relatively poor relatively.
Summary of the invention
The purpose of this utility model is exactly for overcoming the problem that existing artificial membrane-repturing device exists, a kind of novel obstetrics' membrane-repturing device is provided, it has promptly solved the problem of rupture of membranes and amniotic fluid drain simultaneously, the more important thing is the degree of depth that syringe needle penetrates in the time of controlling rupture of membranes preferably, and safety is good.Simultaneously, have simple in structure, easy to operate, advantage of low manufacturing cost.
The purpose of this utility model is achieved through the following technical solutions, this department of obstetrics and gynecology membrane-repturing device comprises air bag, piston pump, suction pipe, sucker, puncture needle, described suction pipe is elongated tubulose, described suction pipe and piston pump are one, the diameter of described piston pump is a bit larger tham the diameter of suction pipe, form step-like at piston pump and suction pipe joint, the front end of described suction pipe connects the sucker of a bell mouth shape, the rear end of described piston pump connects an air bag, be provided with a piston in the described piston pump, a described end that is positioned at the needle body of suction pipe is fixed on the piston, the front end of described needle body stretches out sucker, described sucker is provided with a plurality of suctions hole and communicates with suction pipe, the distance of a is a piston to the distance at the step place that suction pipe and piston pump join on the described piston pump, equal the length that needle body stretches out flat mouthful of sucker, it is the degree of depth of rupture of membranes, because the distance of a has just configured when dispatching from the factory, during use, the length that syringe needle stretches out, the degree of depth that is rupture of membranes is also just certain, overcome that common membrane-repturing device exists only by rule of thumb, often, injure the drawback of fetus because the syringe needle degree of depth can not be controlled preferably.
During use, hold air bag, the gas in the air bag enters piston pump, promote piston advances forward, this moment, needle body stretched out the sucker mouth under the promotion of piston, when the distance of a is zero, be that the forward position of piston and step place are when joining, the length of stretching out of needle body just in time stabs out fetal membrane, at this moment, unclamps air bag, piston moves backward, form negative pressure in the suction pipe, effusive amniotic fluid enters in the suction pipe by the suction hole on the sucker behind the rupture of membranes, has prevented the complication that the amniotic fluid overflow causes.
The beneficial effects of the utility model: 1, simple in structure, easy to operate, only need utilize air bag fill, exit can finish rupture of membranes, to two actions of drain of amniotic fluid.2, because when manufacturing is dispatched from the factory, the distance of a on the piston pump, promptly the needle body degree of depth of stretching out rupture of membranes just configures, has overcome common membrane-repturing device rupture of membranes by rule of thumb, the problem of poor stability.
