Description

Artificial fetal membrane breaking device

Technical Field

The utility model relates to the field of obstetrical medical equipment, in particular to an amnion puncture device.

Background

Women often suffer from uterine contraction and hypodynamia and prolonged labor course during childbirth, and need artificial rupture of membranes. In this case, it is a common practice to puncture the amnion with a needle of a disposable syringe, to discharge the amniotic fluid and then atrophy the amnion, thereby allowing the fetus to be produced through the birth canal. However, the disposable injector has many disadvantages, the penetration depth can not be accurately controlled, and the vagina wall of the fetus and the pregnant woman and medical care personnel are easy to be penetrated. And because the fetus wriggles in the amnion, the puncture position is not well determined, the puncture is easy to deflect, and the operation is difficult.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the defects in the prior art by customers, providing an artificial fetal membrane breaking device which can stably and accurately puncture the amnion.

The utility model adopts the following technical scheme: the utility model provides an artifical rupture of fetal membranes device, it includes a propelling movement section of thick bamboo, push rod, spring, felting needle, a propelling movement section of thick bamboo be both ends open-ended hollow cylinder, be equipped with two backing sheets in the both sides that the upper end of a propelling movement section of thick bamboo corresponds, the push rod upper end is equipped with the propelling movement piece, and the felting needle is installed to the lower extreme, in the propelling movement section of thick bamboo was arranged in to the push rod, the push rod intermediate position be equipped with the spring briquetting, be fixed with a support ring on the inner wall of a propelling movement section of thick bamboo, the centre bore of supporting the ring can make the push rod pass, the spring housing be located.

Preferably, the spring pressing block is of a circular ring structure, and the diameter of the spring pressing block is smaller than the inner diameter of the pushing cylinder.

Furthermore, the limiting block protruding inwards is arranged above the supporting circular ring on the inner wall of the pushing cylinder, and the limiting block can block the spring pressing block from continuing to move downwards.

Preferably, the limiting blocks are multiple and are uniformly distributed on the inner wall of the pushing barrel along a horizontal plane.

Preferably, the limiting block is in a circular ring shape.

Furthermore, the inner wall of the lower end of the pushing cylinder is connected with a conical supporting seat through threads.

Preferably, the lower edge of the supporting seat is provided with a silica gel ring.

The beneficial effects of the utility model reside in that: the spring device is adopted, when the needle is pushed for puncturing, the speed is more stable, the limiting block is utilized to limit the puncturing depth, and the damage to the fetus caused by the too deep needle puncturing can be effectively avoided. The supporting seat is adopted, when puncture is carried out, the supporting seat is attached to the outer portion of the amnion, the puncture position can be more accurate, the puncture position cannot be punctured, and safety is guaranteed. The whole device is ingenious and reasonable in structural design, high in practicability and suitable for popularization and use.

Drawings

Fig. 1 is a schematic diagram of a preferred embodiment of the present invention.

Detailed Description

The invention will be further described with reference to the following examples of the drawings.

As shown in fig. 1, the device for manually breaking the fetal membrane comprises a pushing cylinder 1, a pushing rod 2, a spring 3 and a puncture needle 4, wherein the pushing cylinder 1 is a hollow cylinder with openings at two ends, two supporting pieces 11 are arranged on two corresponding sides of the upper end of the pushing cylinder 1, a pushing block 21 is arranged at the upper end of the pushing rod 2, the puncture needle 4 is arranged at the lower end of the pushing rod 2, the pushing rod is arranged in the pushing cylinder 1, a spring pressing block 22 is arranged in the middle of the pushing rod 2, a supporting ring 12 is fixed on the inner wall of the pushing cylinder 1, a central hole of the supporting ring 12 can enable the pushing rod 2 to pass through, and the spring 3 is sleeved on the pushing rod 2 and positioned between the spring pressing block 22 and the supporting ring 12.

The spring pressing block 22 is of a circular ring structure, and the diameter of the spring pressing block is smaller than the inner diameter of the pushing cylinder 1. An inward-protruding limiting block 13 is arranged on the inner wall of the pushing cylinder 1 above the supporting ring 12, and the limiting block 13 can block the spring pressing block 22 from continuing to move downwards. The limiting blocks 13 are arranged in a plurality and are uniformly distributed on the inner wall of the pushing cylinder 1 along a horizontal plane. The inner wall of the lower end of the pushing barrel 1 is connected with a conical supporting seat 5 through threads. The lower edge of the supporting seat 5 is provided with a silica gel ring 51.
