Abstract
The utility model discloses a disposable medical membrane piercer which comprises a needle tube, a needlepoint, a piston and a cupule. The cupule is located at the front end of the slender needle tube; the piston which can move to-and-fro along the needle tube is arranged in the needle tube; the rear end of the piston is connected with a handspike which is provided with a handle; and the needlepoint is connected at the front end of the piston. When in use, the cupule is buckled on the embryolemma and after the needlepoint stretches out and pierces the embryolemma, the amniotic fluid is sucked into the needle tube by the cupule. The needlepoint is arranged at the front end of the piston in the needle tube, thereby realizing the combination of membrane rupture and amniotic fluid suction and drainage, and by adjusting the length of the needlepoint in the needle tube, the piercing depth can be accurately controlled, thus avoiding to injury to the fetus when the needlepoint goes too deep.
Description
Technical field
This utility model relates to the medical auxiliary apparatus that a kind of department of obstetrics and gynecology use, and especially relates to the just before giving birth rupture of membranes apparatus in the process of a kind of obstetrics.
Background technology
Artificial rupture of membrane is the artificial mode intervention to tear the uteri position amniotic membrane, so that observe amniotic fluid color, reinforcement uterine contraction, acceleration progress of labor, is a kind of induced labor mode comparatively common in the spontaneous labor process.Clinical manipulation is many to be implemented by apparatus with sense of touch under non-direct-view, and the utensil of use mostly is tonger and needle set.Exist the danger of poor, the fetal scalp easy damaged of operation degree of accuracy, and the rupture of membranes afterwaters overflows, may enter the maternal blood circulation along the blood vessel of cervix uteri damage and bring out amniotic embolism.
Summary of the invention
The purpose of this utility model is exactly to overcome the problem that existing artificial rupture of membrane exists, and a kind of Dispoable medical membrane-repturing device is provided, and this membrane-repturing device can accurately be controlled the rupture of membranes degree of depth, reduces rupture of membranes danger, and the drain amniotic fluid has safe and reliable advantage easily.
The purpose of this utility model is achieved through the following technical solutions, this Dispoable medical membrane-repturing device comprises needle tubing, syringe needle, piston, sucker, described sucker is positioned at the front end of elongated needle tubing, being provided with one in the described needle tubing can be along the piston of needle tubing back and forth movement, the rear end of described piston links to each other with the push rod of a band handle, described syringe needle is connected in the front end of piston, not during user mode, the front end of syringe needle is concordant with sucker, the length of the syringe needle that the length of described syringe needle in needle tubing requires when just in time equaling to sting rupture of membranes.
During use, sucker is buckled on the fetal membrane, promote push rod and make the piston reach, this moment syringe needle to stretch out sucker perverse to fetal membrane, when piston moves to the needle tubing front end can not be mobile again the time fully forward, the length that syringe needle stretches out just in time stabs out fetal membrane, after waiting to puncture fetal membrane, piston is moved to the rear end of needle tubing, in the ante-chamber formation negative pressure of piston and needle tubing formation, amniotic fluid is inhaled in the needle tubing by sucker, has prevented that amniotic fluid from overflowing the various complication that caused.
The beneficial effects of the utility model: 1, syringe needle is set, has realized rupture of membranes and absorbed combining of drain amniotic fluid by the piston nose in needle tubing.2, because the length of the syringe needle that the length of syringe needle in needle tubing requires when just in time equaling to sting rupture of membranes, so, by the length of syringe needle in needle tubing is set, just can controls accurately and puncture the degree of depth, prevented that the perverse film of syringe needle from crossing dark harm to fetus.
Description of drawings
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing
Fig. 1 is a cutaway view of the present utility model
Among the figure: 1, needle tubing 2, syringe needle 3, piston 4, sucker 5, push rod 6, handle
The specific embodiment
As shown in Figure 1, this Dispoable medical membrane-repturing device comprises needle tubing 1, syringe needle 2, piston 3, sucker 4, sucker 4 is positioned at the front end of elongated needle tubing, sucker 4 is selected soft elastomeric material for use, needle tubing 1 is selected transparent plastic material for use, being provided with one in the needle tubing 1 can be along the piston 3 of needle tubing 1 back and forth movement, the rear end of piston 3 links to each other with the push rod 5 of a band handle 6, syringe needle 2 is connected in the front end of piston 3, not during user mode, the front end of syringe needle 2 is concordant with sucker 4, the length of the syringe needle that the length of syringe needle 2 in needle tubing 1 requires when just in time equaling to sting rupture of membranes.
During use, sucker 4 is buckled on the fetal membrane, driving handle 6 makes piston 3 reach, this moment syringe needle 2 to stretch out sucker 4 perverse to fetal membrane, when piston 3 moves to needle tubing 1 front end can not be mobile again the time fully forward, the length that syringe needle 2 stretches out just in time stabs out fetal membrane, after waiting to puncture fetal membrane, piston 3 is moved to the rear end of needle tubing 1, in the ante-chamber formation negative pressure of piston 3 and needle tubing 1 formation, amniotic fluid is inhaled in the needle tubing 1 by sucker 4, has prevented that amniotic fluid from overflowing the various complication that caused.
Claims (2)
1, a kind of Dispoable medical membrane-repturing device, it is characterized in that this Dispoable medical membrane-repturing device comprises needle tubing, syringe needle, piston, sucker, described sucker is positioned at the front end of elongated needle tubing, being provided with one in the described needle tubing can be along the piston of needle tubing back and forth movement, the rear end of described piston links to each other with a push rod, and described syringe needle is connected in the front end of piston.
2, a kind of Dispoable medical membrane-repturing device according to claim 1 is characterized in that the length of the syringe needle that the length of described syringe needle in needle tubing requires when just in time equaling to sting rupture of membranes.
