A simple water bag and a simple water bag tool kit for mid-term induction of labor

Technical Field

The utility model relates to an induction labor instrument, in particular to a simple water bag used for mid-term induction labor, and also to a simple water bag tool kit used for mid-term induction labor.

Background technique

Clinically, some pregnant women have many comorbidities and complications, and their conditions are serious. Because of maternal diseases, such as serious heart, liver, kidney, blood system, hypertension and other diseases, it is not suitable to continue the pregnancy. In addition, due to abnormal liver and kidney function, it is often not suitable to use drugs such as rivanol, mifepristone combined with misoprostol to induce labor. In this case, water bag induction of labor is an appropriate choice.

Water bag induction of labor refers to placing a sterile water bag between the uterine wall and the fetal membrane, and inducing uterine contractions through the mechanical stimulation of the water bag, promoting the expulsion of the fetus and placenta. In addition to mechanical stimulation, the mechanism of action of water bag induction of labor can also cause local detachment of fetal membranes, degeneration of the decidua, focal necrosis, and release of endogenous prostaglandins to cause uterine contractions. The uterine contractions of water bag induction of labor are relatively mild and more controllable. If forced uterine contractions occur, the water bag can be removed at any time. Patients have good tolerance, and it is especially suitable for patients with heart, liver, kidney and other diseases in the mother, or those with liver and kidney dysfunction who are not suitable for drug induction of labor, or patients with scarred uterus who are not suitable for other induction methods.

The advantages of water bag induction of labor are mechanical action, no drug effect on the human body, simple and safe operation. At present, the water bag induction of labor in the second trimester used in clinical practice is often a ready-made product, but the ready-made product is expensive, such as the cook water bag, which is difficult to popularize in primary hospitals.

Embodiment 2

A simple water bag tool kit for mid-term induction of labor comprises: a. a simple water bag for mid-term induction of labor, b. an auxiliary guide wire temporarily placed in a water injection hose to assist the water injection hose in inserting an elastic water bag, c. a syringe connected to the rear end of the water injection hose to perform air tightness detection and water injection on the elastic water bag, and d. a packaging bag for placing the simple water bag that is not filled with water.

The elastic water bag, the water injection hose and the two fixing lines are tied as a whole and placed in a packaging bag, one sealing rope is placed in the packaging bag in an untied state, and another sealing rope is also placed in the packaging bag in an untied state as a spare sealing rope.

If the first tying point, the second tying point or the sealing tying point becomes loose or leaks during the water filling process or use, the spare sealing tying rope shall be tied at the loose or leaking place so that the simple water bag can continue to be filled with water or used normally.

The auxiliary guide wire is a steel wire.

The method of making a simple water bag is as follows:

Step 1: Use scissors to cut off the rear end of the single-lumen urinary catheter 29 cm away from the catheter end.

Step 2: Place the steel wire into the single-lumen urinary catheter, and insert two condoms into the single-lumen urinary catheter respectively, so that the two condoms form a double-layer water bag structure.

Step 3: Use a silk thread to tie the condom to form a first tying point 4.5 cm away from the front end of the single-lumen catheter, and use another silk thread to tie the condom to form a second tying point 1.5 cm away from the first tying point. The tightness of the tying should be appropriate. On the one hand, it should be able to manually remove the steel wire from the single-lumen catheter and keep the single-lumen catheter conductive after the steel wire is removed. On the other hand, it should be able to ensure that the condom fits tightly against the single-lumen catheter without leaking air or water during air-tightness testing or water injection.

Step 4: Remove the steel wire from the single-lumen catheter, connect the rear end of the single-lumen catheter to a 50ml syringe, pump air into the condom, and test the air tightness of the simple water bag. During the inflation process, the syringe is disconnected from the single-lumen catheter when sucking air. At this time, the auxiliary clamp can be used to temporarily clamp the rear end of the single-lumen catheter to prevent the simple water bag from leaking. After the syringe is fully pumped with air, it is connected to the rear end of the single-lumen catheter and continues to pump air; inject 300ml of air into the simple water bag, and after observing that the simple water bag has no leakage, remove the auxiliary clamp and syringe.

Step 5: Place the simple water bag without water filling and a hemp rope made in step 4 into the packaging bag without tying them. Place another hemp rope as a spare into the packaging bag without tying them. Disinfect the packaging bag and the contents therein.

Step 6. Before using the simple water bag, connect the rear end of the single-lumen urinary catheter with a syringe, slowly inject 200-500 ml of normal saline into the simple water bag, fold the rear section of the water injection hose back and tie it with a hemp rope to form a sealed binding point, and keep the other hemp rope for later use.
