Abstract

An artificial membrane rupturing device for a delivery room solves the problems that the existing artificial membrane rupturing device is easy to puncture a fetus and other tissues in a delivery passage and is easy to puncture an operator; the puncture device comprises a handle, wherein a moving rod is connected with the handle in a threaded manner, the moving rod penetrates through the handle forwards and backwards, a puncture piece is fixedly connected to the front end of the moving rod, the puncture piece is arranged at the eccentric position of the front end of the moving rod, and an operation rotating cap is fixedly connected to the rear end of the moving rod; the utility model has low cost and simple operation, which can make it have the condition of disposable articles and prevent and reduce the chance of cross infection in operation; and the safety is higher, thereby avoiding stabbing fetuses and operators and reducing the physical and psychological pressure of the lying-in women.

Description

Artificial membrane rupture device for delivery room

Technical Field

The utility model belongs to the technical field of medical instrument, especially, relate to an artificial rupture of membranes ware in delivery room.

Background

The manual membrane rupturing device is an important measure for promoting labor progress and observing the indoor condition of a fetus, the previous operation is often implemented by means of a device through touch under non-direct vision, the used device is mostly a clamp and a needle, and doctors mostly use a syringe needle to puncture a fetal membrane to make amniotic fluid flow out clinically, however, the mode is inconvenient to operate, the needle is relatively sharp, the fetus and other tissues in a birth canal are easily punctured, an operator is also easily punctured, and more physical and psychological pressure is brought to a parturient.

SUMMERY OF THE UTILITY MODEL

To the technical problem, the utility model provides a delivery room manual membrane rupture device has solved current manual membrane rupture device and has easily stabbed other tissues in foetus and the birth canal, also easily stabbed operator's problem simultaneously.

In order to achieve the above purpose, the utility model provides the following technical scheme; the handle is connected with a moving rod in an internal thread mode, the moving rod penetrates through the handle from front to back, a membrane puncturing piece is fixedly connected to the front end of the moving rod, the membrane puncturing piece is located at the eccentric position of the front end of the moving rod, and an operation rotating cap is fixedly connected to the rear end of the moving rod.

Preferably, the membrane puncturing piece is knife-shaped and made of a hard plastic sheet.

Preferably, the length of the membrane puncturing piece is not more than 0.5 cm.

Preferably, the length of the handle is 8-12 cm.

Preferably, the rear end of the handle is provided with a mark area.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model has low cost and simple operation, which can make it have the condition of disposable articles and prevent and reduce the chance of cross infection in operation; and the safety is higher, thereby avoiding stabbing fetuses and operators and reducing the physical and psychological pressure of the lying-in women.

The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention, and together with the description serve to explain the invention and not to limit the invention. In the drawings:

fig. 1 is a schematic view of the overall structure of the present invention.

Fig. 2 is a schematic structural view of the connection between the handle and the moving rod of the present invention.

Fig. 3 is an enlarged schematic view of a portion a in fig. 1.

Fig. 4 is an enlarged schematic view of a portion B in fig. 1.

In the figure: 1-handle, 2-moving rod, 3-membrane puncturing piece, 4-operating screw cap and 5-marking area.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. The attached drawings are simplified schematic diagrams, and only illustrate the basic structure of the present invention in a schematic manner, and thus only show the components related to the present invention.

Referring to fig. 1-4, the utility model discloses a

handle

1, 1 female connection of handle has carriage release lever 2, carriage release lever 2 runs through handle 1 around to, the front end fixed connection of carriage release lever 2 has thorn membrane piece 3, thorn membrane piece 3 is in the eccentric position department of 2 front ends of carriage release lever, the rear end fixed connection of carriage release lever 2 has the operation to revolve cap 4.

When the puncture membrane device is used, sterile gloves are worn firstly, the handle 1 is held by a hand, the hand is inserted into the vagina in a hand posture with the middle finger and the index finger in parallel, the cervix and the amniotic sac are instructed to be probed, after the probing is finished, the movable rod 2 is rotated by operating the screw cap 4 when the membrane is to be broken, the handle 1 is held and fixed while the movable rod 2 is rotated, so that the movable rod 2 can slowly move towards the front end of the handle 1 and penetrate out of the handle 1 at the same time of the rotation, the puncture membrane 3 can scratch the fetal membrane in the process of driving the puncture membrane device 3 to move towards the uterus by the movable rod 2, as the movable rod 2 is in threaded connection with the handle 1, and the screw pitch of the thread is small, the amount of inward movement of the movable member 2 is small when the screw cap 4 is operated once, thus the puncture membrane device can avoid the injury to the advantages of the fetus and other tissues in the birth canal, is safer, and the puncture membrane device 3 is arranged in the handle 1 at the beginning, the operator is not hurt when the puncturing film is inserted and rotated.

Wherein, in order to avoid the puncture of the fetus by the metal sharp object, the puncture membrane member 3 is knife-shaped and made of hard plastic sheet.

Wherein the length of the membrane puncturing piece is not more than 0.5 cm.

Wherein, the length of the handle 1 is 8-12 cm.

Wherein, in order to facilitate the operator to distinguish the insertion depth of the handle 1, the back end of the handle 1 is provided with a mark area 5.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
