For the description of the structure of the other parts of the membrane rupturing device in this embodiment, reference may be made to embodiment one, and details are not repeated here.
The using method comprises the following steps:
when the membrane rupture device in the embodiment is used, the following steps can be referred to:
1. firstly, the elastic piece 205 is pushed to draw outwards and abut against the limiting ring B103, at the same time, the baffle ring 204 is positioned in the second conventional section 112, the insertion end of the membrane breaking device is inserted into the pudendum part, the flexible layer 5 is tightly attached to the amnion, then the adsorption piston is outwards rotated through the outward-rotating handle, the space of the adsorption chamber is increased, namely the distance between the adsorption piston and the limiting ring B103 is increased, the vacuum degree of the adsorption chamber is increased, and the amnion is adsorbed on the flexible layer through the adsorption channel;
2. the cylinder body 1 is pulled outwards, so that the amnion and the infant generate a certain separation distance;
3. the blocking ring 204 is pushed forwards quickly through the push rod, so that the blocking ring 204 enters the ventilation section from the second conventional section under the action of inertia force, a ventilation gap is formed between the outer peripheral wall of the blocking ring 204 and the wall of the ventilation section, in the process, gas between the tool bit seat 201 and the amnion is divided into two paths, one path is discharged outwards through a drainage channel, the path is a main exhaust path, the other path enters the ventilation section through the mixing hole 20101 and then enters a vacuum area between the blocking ring 204 and the adsorption piston from the ventilation gap, and the mixing hole 20101 has a flow limiting effect, so that the flow of the path is small, the pressure compensation effect is only achieved, the tool bit seat 201 is pushed forwards conveniently and continuously, and the adsorption on the amnion is not influenced;
4. when the scalpel head seat 201 is pushed forward to exceed the head hole 301 quickly and impacts the amnion quickly, the scalpel head 202 on the scalpel head seat 201 breaks the amnion before the adsorption force on the amnion is released.
In this embodiment, the reasonable structural design of rupture of membranes ware for the amnion can be adsorbed and draw outward and with the intra-amniotic baby certain distance apart, on the one hand because the amnion is adsorbed when rupture of membranes props up, tool bit 202 can be comparatively easy accurate with the amnion rupture, rupture of membranes degree of accuracy and efficiency all improve greatly, on the other hand because the amnion is with the intra-amniotic baby certain distance apart during rupture of membranes, can further prevent that the baby from being stabbed, improved the security of operation greatly.
The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.
