Description

Technical Field

[0002] Vacuum extraction is a vaginal delivery method that uses the principle of negative pressure. The vacuum cleaner is placed on the fetal head. After a certain negative pressure is formed, traction or rotation is performed to assist the delivery of the fetus. Vacuum extraction is not used as a routine delivery method. It is only used as an auxiliary method when the cervix is ​​fully dilated and the doctor has ruled out contraindications such as birth canal obstruction, and the second stage of labor needs to be shortened as soon as possible. However, during the vacuum extraction process, some fetal heads may develop tumors or subcutaneous hematomas due to the negative pressure.

The connecting vertical pipe 10 is fixedly connected to the bottom of the upper placement pipe 9, and the adsorption end 11 is fixedly connected to the lower end of the connecting vertical pipe 10.

[0029] The outer wall diameter of the connecting vertical pipe 10 is consistent with the diameter of the push opening 34, the outer wall of the outer ring of the connecting bearing 23 is fixedly connected to the inner wall of the connecting vertical pipe 10, a sliding ring groove 36 is opened on the top of the connecting vertical pipe 10, and the bottom sliding ring 28 slides in the sliding ring groove 36, and a discharging protrusion 37 is fixedly connected to the inner wall of the connecting vertical pipe 10, and the adsorption end 11 is made of silicone material.

[0030] The internal movable member 4 is slidably arranged in the connecting vertical pipe 10, and the internal movable member 4 includes a vertical pipe shaft 12 and a rubber plug 13. The rubber plug 13 is fixedly arranged at the lower end of the vertical pipe shaft 12. The upper end of the vertical pipe shaft 12 is provided with spiral grooves 38 in a linear array. Double-sided snap-fit ​​grooves 39 are opened on both sides of the vertical pipe shaft 12, and the dispensing protrusions 37 are inserted into the double-sided snap-fit ​​grooves 39.

[0031] The spiral groove 38 is engaged with the spiral protrusion 29 .

[0032] During specific use, the operator holds the connecting vertical pipe 10, with the upper placement pipe 9 facing the operator and the side slot 40 of the upper placement pipe 9 facing upward, and adsorbs the adsorption end 11 on the top of the fetus's head. The contact area is increased by the friction slot 30, which is convenient for the operator to turn the package pushing ring 8, and the inner meshing ratchet ring 25, the connecting pipe 26 and the bottom connecting ring 27 rotate synchronously. The inner meshing ratchet ring 25 rotates outside the outer meshing gear 14, and the outer meshing gear 14 locks the inner meshing ratchet ring 25 to prevent the inner meshing ratchet ring 25 from rotating. As the internal rotating member 7 rotates, the bottom The upper connecting ring 27 rotates synchronously, and the spiral protrusion 29 is engaged with the spiral groove 38. When the bottom connecting ring 27 rotates, the expenditure protrusion 37 fixed to the inner wall of the connecting vertical tube 10 is engaged in the double-sided engaging groove 39, and the vertical pipe axis 12 moves upward in the connecting vertical tube 10. The rubber plug 13 moves upward in the connecting vertical tube 10, and the space in the connecting vertical tube 10 below the rubber plug 13 forms a negative pressure. The adsorption end 11 fits tightly to the fetal head, and the fetal head is pulled or rotated. When the occipital part of the fetal head reaches the lower edge of the pubic symphysis, the operator lifts the suction device to extend the fetal head for delivery.

[0033] During the operation, the external hand-gripping member 3 is held in the operator's hand throughout the whole process and is in a relatively static state. The rotating pushing member 2 is moved and rotated in the upper placement pipe 9. Since the insertion support member 6 is fixedly connected to the connecting pipe 26 of the internal rotating member 7, the rotation of the connecting pipe 26 has a certain impact on the insertion support member 6. However, since the support base plate 22 and the connecting pipe 26 are connected by the connecting bearing 23, the impact of the rotational force on the insertion support member 6 is greatly reduced. In addition, since the support column 21 of the insertion ring support member is inserted in the movable opening 19 of the external meshing gear 14, even if the support column 21 rotates, it will not have a substantial impact on the external meshing gear 14.

[0034] When the biparietal diameter of the fetal head is pulled out of the vaginal opening, the operator presses the pressing cover 18, and the engaging groove 20 of the pressing cover 18 moves downward along the engaging protrusion 35 on the inner wall of the wrapping tube 32, and the gasket 16 and the extension tube 15 fixed to the pressing cover 18 push the outer meshing gear 14 to move along the support column 21 toward the support base plate 22. During this process, the outer meshing gear 14 moves downward and is misaligned with the inner meshing ratchet ring 25, and the inner meshing ratchet ring 25 is no longer locked and restricted. The reset spring 17 is squeezed and compressed, and the support spring 24 is squeezed and compressed. The operator pushes the wrapping push ring 8 in the opposite direction, and the vertical pipe axis 12 moves downward. The rubber plug 13 moves downward in the connecting vertical pipe 10, and the space below the auxiliary rubber plug 13 restores positive pressure, quickly separating the adsorption end 11 from the fetal head, and assisting delivery according to the delivery mechanism to deliver the fetal shoulder and fetal body.

[0035] The above is the overall workflow of the present invention, and you can repeat this step next time you use it.

[0036] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0037] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
