Artificial membrane rupture needle

Abstract

The invention relates to the technical field of medical treatment, in particular to an artificial membrane rupture needle, and aims to solve the problem that a fetus is likely to injure when an existing membrane rupture needle body is utilized to perform membrane rupture on a pregnant woman with an inconspicuous amniotic sac. For this purpose, the artificial membrane rupture needle of the invention comprises a needle body and a needle handle; the needle body is connected with the needle handle; the needle handle communicates with a suction cup; a negative pressure device is arranged in the needle handle; the negative pressure device provides negative pressure to the suction cup; a first through hole allowing the needle body to pass through is reserved in the middle part of the suction cup;the distance between the needle body and the needle handle can be adjusted. According to the artificial membrane rupture needle of the invention, the suction cup is installed, a fetal membrane is punctured after being moved backwards through negative pressure adsorption; the artificial membrane rupture needle is convenient to use, and for the pregnant woman with the inconspicuous amniotic sac, since the fetal membrane is next to the head of a fetus, the fetal membrane is punctured after being sucked and pulled backwards to avoid that the body of the fetus is injured, so that the risk of membrane rupture with an ordinary needle is greatly lowered, namely that blind zone operations are reduced, the safety factor is high, and medical disputes are avoided.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to an artificial water breaking needle. Background technique [0002] Doctors may consider artificially induced labor when continuing the pregnancy is at greater risk to the mother or fetus. Artificial water breaking is the use of sterile instruments to tear the amniotic fluid membrane, so that the amniotic fluid flows out, prompting the production of uterine contractions, and achieving the purpose of promoting the progress of the labor process. However, the water-breaking needles used in clinical practice are generally performed blindly during the operation. For pregnant women whose amniotic sac is not obvious, the risk is relatively high, and it is easy to damage the fetus and cause medical disputes. [0003] Correspondingly, a new artificial water breaking needle is needed in the art to solve the above problems. Contents of the invention [0004] In order to solve the above-...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above-mentioned problems in the prior art, that is, in order to solve the problem that pregnant women with inconspicuous amniotic sacs are likely to damage the fetus when using the existing water-breaking needle to break the water, the present invention provides an artificial water-breaking needle, which is improved in that it includes Needle body and needle handle, the needle body is connected with the needle handle; the needle handle is connected with a suction cup, the inside of the needle handle is provided with a negative pressure device, and the negative pressure device is the The suction cup provides negative pressure; the middle part of the suction cup is reserved with a first through hole that allows the needle body to pass through, and the distance between the needle body and the needle holding handle can be adjusted
