Embodiment Construction

[0025] refer to figure 1 , the ruptured membrane sucker, comprising a sucker disc body (1), the tail end of the disc body (1) is connected with a rod tube (2), and the rod tube (2) is connected to an air pressure controller through a flexible pipe (21) The air compressor (22) is connected. The disc body (1) is made of flexible material, and the disc body can also be wrapped with flexible material, and the flexible material can be selected from silica gel which is non-irritating to the human body.

[0026] The air compressor (22) is also provided with an amniotic fluid collection chamber (not marked in the figure), and the present invention can collect the amniotic fluid that punctures the amniotic membrane and flows out within a certain range through the suction cup and the rod tube.

[0027] refer to Figure 2 to Figure 5 , the disc body (1) is provided with a main suction duct (3) that runs through the disc body (1) and a pair of auxiliary parts that communicate with the m...

Abstract

The invention discloses a film breaking suction disk which comprises a suction disk body, wherein the tail end of the disk body is connected with a rod pipe; a main air suction pipeline penetrating through the disk body and an auxiliary air suction pipeline with one end communicated with the main air suction pipeline and the other end penetrating through the surface of the disk body are arranged in the disk body; a thin film leaf valve is arranged at the communicated part of the auxiliary air suction pipeline and the main air suction pipeline; a chamber is arranged in a position where the auxiliary air suction pipeline penetrates through the surface of the disk body; an air plug plate is arranged in the chamber; one end of the air plug plate is hinged to the inner wall of the chamber, and the other end of the air plug plate is fixed at one end of a spring; the other end of the spring is fixed on the inner wall of the chamber; and a film breaking hook is fixed on the outer side of the air plug plate. The film breaking suction disk disclosed by the invention can break a film at one step through blind operation with one hand, and is convenient to use, simple in step, scientific and reasonable in structure, ingenious in design and high in safety.

Description

technical field [0001] The invention relates to a membrane rupture sucker, which belongs to the technical field of IPC No. A61B17. Background technique [0002] Artificial rupture of membranes is a basic clinical technique commonly used in obstetrics. It is a way of inducing labor by artificially intervening to tear the amniotic membrane at the cervix in order to observe the color of amniotic fluid, strengthen uterine contractions, and accelerate the progress of labor. [0003] At present, most of the artificial rupture of membranes is carried out with the help of tactile instruments under non-direct vision. Most of the membrane rupture devices used are forceps or needles, which are clumsy in operation and may easily cause damage to the cervix and fetal scalp. [0004] And though some tools are improved in structure, there are still certain difficulties in operation, such as Chinese Patent Publication No.: CN204814111U disclosed disposable artificial rupture crochet needle, ...
