Negative-pressure clamping type membrane rupture device for obstetrical department and use method thereof

Abstract

The invention discloses a negative-pressure clamping type membrane rupture device for the obstetrical department and a use method thereof. The negative-pressure clamping type membrane rupture device comprises a working barrel; a piston is slidably connected into the working barrel; a piston space is formed between the piston and a fetal membrane; the working barrel is fixedly connected with a fixing plate; the piston is fixedly connected with an air path sealing rod, and the air path sealing rod penetrates through the fixing plate and is slidably connected with the fixing plate; a membrane clamping mechanism is connected to one end, close to the fetal membrane, of the air path sealing rod; a positioning groove matched with the air path sealing rod is formed in one end, close to the fetal membrane, of the fixing plate; an air inlet channel is further formed in the air path sealing rod; a sliding groove is further formed in the piston; an ejection connecting rod is slidably connected into the sliding groove; the ejection connecting rod penetrates through the fixing plate and is slidably connected with the fixing plate; and a membrane rupture mechanism is connected to the end, close to the fetal membrane, of the ejection connecting rod. The device is easy to operate, membrane rupture work is carried out after the fetal membrane is clamped, a membrane rupture needle automatically rebounds after the membrane rupture work is carried out, a fetus is prevented from being scratched, amniotic fluid collection work is facilitated, and the use safety of a product is improved.

Description

Technical field [0001] The present invention belongs to the technical field of broken membrane, and in particular, a negative pressure clamping film apparatus for obstetrics and its use. Background technique [0002] In obstetrics and gynecology, the amniotic fluid will naturally break the amniotic fluid in general, so that the fetus is released, but the maternal woman is in a matrix, and the mother-in-law, The method helps production, at which time medical staff are required to puncture amniotic fluid drainage. Artificial breakage, is the human way to intervene, to tear the mounted membrane of the palace, in order to observe the color of the amniotic fluid, strengthen the contrast, accelerate the progress of the production, and apply the film. [0003] At present, the existing broken membrane devices are mostly pierced by the needle of the fetus, so that the amniotic fluid flows out; this instrument is completely experienced by the medical staff during the film, and the accuracy...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the existing membrane rupture devices directly puncture the amniotic membrane including the fetus through a needle, so that the amniotic fluid flows out; this kind of device completely relies on the experience of medical staff to operate the membrane rupture, and the accuracy of membrane rupture is low. Moreover, the size of the opening cannot be controlled during the operation, which often leads to the opening being too large, and the amniotic fluid flows out quickly and in large quantities, resulting in the inability to collect the amniotic fluid. and maternal life-threatening; and the cleaning of amniotic fluid is also more troublesome
