Description

An artificial membrane rupture device

technical field

The utility model relates to a medical auxiliary device, in particular to an artificial membrane rupturer.

Background technique

Artificial rupture of membranes is an artificial way of intervening to tear the amniotic membrane at the cervix in order to observe the color of the amniotic fluid, strengthen the contractions, and accelerate the progress of the labor process. At present, puncture needles or needle holders are often used in clinical practice. The puncture needle is easy to puncture the operator, increasing the chance of occupational exposure, and also causing adverse effects on the mother and the fetus; sometimes the puncture needle only pierces a small eye, and after the amniotic fluid flows out, the amniotic sac is still wrapped around the fetal head, and there is no risk. Complete rupture of the membrane. The needle holder tip is blunt, and the success rate of puncture is low.

SUMMARY OF THE INVENTION

In order to overcome the deficiencies of the prior art, the purpose of this utility model is to provide a kind of artificial membrane rupture device, by manually twisting the inner cylinder to achieve artificial membrane rupture, the membrane rupture success rate is high.

The technical scheme of the utility model is: an artificial membrane rupture device, which is characterized in that: it comprises three parts: an outer cylinder, an inner cylinder and a membrane-breaking cutting blade; the inner diameter of the outer cylinder is larger than the inner diameter of the inner cylinder, and the outer cylinder (1) A finger collar (4) is attached on the outside, the finger collar is fixedly connected with the outer cylinder, and is located 2cm away from the head end of the outer cylinder; thread;

The inner cylinder (2) is provided with 6 cutting blades (3) at the head end of the inner cylinder; the outer surface of the inner cylinder is provided with an external thread that fits with the outer cylinder, and the outer side of the tail end of the inner cylinder is provided with an anti-slip concave The slot (8) and two wings (5) are provided with holes (6) at the top of the tail end.

The utility model is a hollow structure with a length longer than that of the outer cylinder, and when the inner cylinder rotates forward, the protruding length of the cutting blade does not exceed 1 mm.

The inner cylinder of the utility model has a hollow structure, and sharp cutting blades are scattered at the head end of the inner cylinder, which can be used to cut the amniotic sac. The other end of the inner cylinder of the utility model, that is, the outer tail end, is provided with anti-skid threads and two wings, which is convenient for the left hand to rotate the membrane during operation.

There is a rotating thread between the inner cylinder and the outer cylinder, which is easy to rotate. The thread restricts the cutting blade of the rotating rod to protrude out of the outer cylinder at most 1mm, which can cut the amniotic sac and prevent the head of the newborn from being cut.

The working principle of the utility model is as follows: during the vaginal inspection of the utility model, the head end of the utility model is brought into the vagina by inserting the index finger of the right hand into the finger loop arranged on the side of the outer cylinder; during the interval of contractions, the head end of the outer cylinder is touched. For the amniotic sac, fix the outer tube with the thumb and middle finger of the right hand, and rotate the inner tube with the left hand. When amniotic fluid is found to gush out of the hole of the inner tube, it indicates an effective membrane rupture.

The beneficial effects of the utility model are as follows: 1. The utility model has a simple structure and is convenient to operate, and the membrane can be ruptured manually by manually twisting the inner cylinder, and the success rate of membrane rupture is high. 2. The utility model is safe to use, not only can effectively avoid occupational exposure of the operator, but also will not cause harm to the mother and the fetus. 3. The inner tube of the utility model can drain part of the amniotic fluid, which is convenient for observing the properties of the amniotic fluid. When the outflow rate of the amniotic fluid is too fast, the right thumb can be used to block the hole of the inner tube to prevent the umbilical cord from prolapse, which has a good clinical application prospect.

Description of drawings

Figure 1 is an overall schematic diagram of an artificial membrane rupturer of the present invention.

Detailed ways

As shown in Figure 1, an artificial membrane rupture device includes three parts: an outer cylinder, an inner cylinder and a membrane rupture cutting blade. The outer side of the outer cylinder 1 is fixed with a finger collar 4, the head end of the inner cylinder 2 is provided with a cutting blade 3, the tail end is provided with two wings 5, an eyelet 6 and an anti-slip groove 8, and the inner cylinder and the outer cylinder are provided with matching threads. 7.

The utility model also designs that the inner cylinder is a hollow structure, the inner cylinder can be rotated, and the rotation sends the cutting blade into the membrane rupture, and can be turned back immediately after the membrane rupture is completed.

The utility model also designs the cutting blade, and the purpose of designing a plurality of cutting blades is to improve the success rate of membrane rupture, pierce the amniotic sac as much as possible, and avoid incomplete membrane rupture.

The use method of the utility model is as follows: when the utility model is inspecting the vagina, the utility model is brought into the vagina by inserting the index finger of the right hand into the finger loop arranged on the side of the outer cylinder. During the interval of uterine contractions, touch the head of the outer tube to the amniotic sac, fix the outer tube with the thumb and middle finger of the right hand, and rotate the inner tube with the left hand.
