Embodiment 1

[0023] Embodiment one, such as Figure 1-2 As shown, the obstetrics and gynecology delivery rupture device includes a syringe 1, the upper and lower sides of the syringe 1 are smooth planes and the front and back are arc surfaces respectively, the interior of the syringe 1 is a cavity structure, and the syringe 1 1 can be made of existing hard non-toxic silica gel, and the inner side of the left end of the syringe 1 is slidingly installed with a rupture needle 2. The membrane rupture needle 2 can be selected from an existing sterilized membrane rupture needle. The right end of the film needle 2 is fixedly installed with a push plate 3 that is slidably installed in the cavity of the syringe 1 from left to right, and a compression spring 4 is respectively installed between the front and rear ends of the push plate 3 and the left end of the syringe 1. The model of stage clip 4 is selected according to specific needs, and the right end of described push plate 3 is fixedly installe...

Embodiment 2

[0026] Embodiment two, on the basis of embodiment one, such as figure 1 with image 3 As shown, the upper and lower sides of the syringe 1 are respectively slidably mounted with fan-shaped plates 6 up and down. The upper and lower sides of the two fan-shaped plates 6 are respectively arc-shaped surfaces and are arranged away from each other. The two fan-shaped plates 6 are respectively optional. Made of non-toxic rubber material, the upper and lower sides of the syringe 1 are respectively fixed with limit rods that run through the two fan-shaped plates 6. Through the action of the two limit rods, the two fan-shaped plates 6 Can only move up and down, can not swing freely, the right end of the syringe 1 is fixedly installed with a support round rod 7, the right end of the push rod 5 is set through the support round rod 7, and the support round rod 7 is coaxially slid left and right There is a push ring 8, and connecting rods 9 are respectively hinged between the right ends of ...

Embodiment 3

[0028] Embodiment three, on the basis of embodiment two, such as Figure 2-3 As mentioned above, the lower end of the push rod 5 is fixedly equipped with a rack 12, the density of teeth on the rack 12 is selected according to specific needs, and the lower end of the syringe 1 is rotatably equipped with an adjusting gear meshed with the rack 12. 13, such as figure 1 As shown, the right end of the fan-shaped plate 6 below is provided with a display groove, the adjustment gear 13 is rotatably mounted on the lower end of the syringe 1 and is located in the display groove, and a scale 14 is provided on the front side of the adjustment gear 13 to display The setting of the groove can facilitate reading the scale 14, and the bottom surface of the syringe 1 is fixedly equipped with a pointer 15 positioned in front of the scale 14;

[0029] When in use, the medical staff holds the syringe 1 in one hand, and pushes the push rod 5 to slide to the left with the other hand. At this time, ...

Abstract

The invention provides a membrane rupture device for delivery in the obstetrics and gynecology department. The problems that an existing pricking needle is inconvenient to hide, amniotic fluid in a fetal membrane cannot be collected, and the pricking depth is difficult to control when the existing pricking needle is used are effectively solved. The membrane rupture device comprises a needle cylinder, wherein a membrane rupture needle is mounted on the inner side of the left end of the needle cylinder in a left-right sliding mode, a push plate mounted in the needle cylinder in a left-right sliding mode is fixedly mounted at the right end of the membrane rupture needle, pressure springs are mounted between the push plate and the left end of the needle cylinder, and a push rod penetrating through the right end surface of the needle cylinder is fixedly mounted at the right end of the push plate. Through cooperative use of the push rod, the push plate and the pressure springs, the membrane rupture needle can be rapidly contracted, and damage to the birth canal of a puerpera or damage to other tissues is avoided; and through cooperative use of liquid collecting bins and a negative pressure device, amniotic fluid can be collected, pollution caused by the amniotic fluid is prevented, membrane rupture work can be performed more conveniently, and pains of pregnant women are correspondingly reduced.

Description

technical field [0001] The invention relates to the technical field of obstetrics and gynecology, in particular to a delivery membrane rupturer for obstetrics and gynecology. Background technique [0002] With the rapid development of society and the improvement of medical level, the treatment of problems during gynecological childbirth is becoming more and more standardized. During childbirth, if the amniotic membrane of the parturient is not ruptured normally, the amniotic membrane of the parturient needs to be ruptured by a membrane rupture device. , so as to ensure the normal delivery of the mother. [0003] The traditional method is to rupture the amniotic membrane of the parturient by puncturing needles. However, the existing puncturing needles have the following problems during use: [0004] 1. The existing puncture needles are inconvenient to hide, which may easily cause maternal birth canal damage or other tissue damage, and the amniotic fluid in the fetal membrane...
