the outer diffusion layer 82 is made of hard materials, the gas change layer 83 is made of elastic materials, the central bearing layer 81, the outer diffusion layer 82 and the gas change layer 83 are of an integral structure, when gas is blown into the outer diffusion cavity 10, the gas change layer 83 deforms under the extrusion action of the gas, so that the outer diffusion layer 82 approaches to the inner wall of the annular spherical groove and performs mutual extrusion action, the connection strength between the outer sealed air bag 11 and the gas compression ring 2 is effectively enhanced, one ends of the outer diffusion layer 82 and the gas change layer 83, which approach to the inner wall of the annular spherical groove, are fixedly connected with a plurality of silica gel bulges 13 which are uniformly distributed, the silica gel bulges 13 are of hemispherical structures, when the outer diffusion layer 82 approaches to the inner wall of the annular spherical groove under the extrusion action of the gas, the silica gel bulges 13 firstly contact with the inner wall of the annular spherical groove, and meanwhile, under the condition that more and more gas is filled, the extrusion force applied to the silica gel bulges 13 is increased, will deform gradually and become flat, thus can form multiunit to cut off between external seal gasbag 11 and expander ring 8, make joint strength and leakproofness show and improve.
Please refer to fig. 6, a plurality of embedded recessive balls 7 are embedded in the handle 3 and are uniformly distributed, the embedded recessive balls 7 are completely located inside the handle 3, so that the surface of the handle 3 is kept in a smooth state, friction on the birth canal of a puerperal woman is not easy to cause, the pain degree of the puerperal woman is effectively reduced, the handle 3 is made of latex materials, the embedded recessive balls 7 are formed by pressing the latex materials, the compression ratio is 1.5-2 times, the hardness of the embedded recessive balls 7 is larger than that of the handle 3, when a doctor holds the handle 3, the touch sense with different obvious hardness can be realized, so that the surface of the handle 3 is kept smooth, the antiskid effect can be realized, the doctor is effectively helped to hold the handle 3 to place the obstetric apparatus into the birth canal, the birth canal is expanded, smooth and accurate operation is effectively guaranteed, and the pain.
By the double-layer air bag structure of the outer sealed air bag 11 and the inner semi-permeable air bag 12, when the air bag expands the birth canal, the speed of inflation is not easy to be too fast, the occurrence of discomfort of the lying-in woman caused by too fast opening of the birth canal is effectively avoided, meanwhile, in the later stage of the augmentation birth canal, after the outer sealed air bag 11 and the inner semi-permeable air bag 12 are separated, the air is gradually introduced between the outer sealed air bag 11 and the inner semi-permeable air bag 12 under the action of the expansion pressing ring 8, at the moment, under the action of the air, the two sides of the expansion pressing ring 8 extend and extrude towards the inner wall of the annular ball groove, the extrusion force of the air is increased along with the gradual increase of the air, the effect that the joint strength and the leakproofness of external seal gasbag 11 and atmospheric pressure ring 2 are stronger and stronger can be realized, the condition that gas leakage or gasbag drop takes place effectively, the security when effectively improving the boosting.
The above; but are merely preferred embodiments of the invention; the scope of the invention is not limited thereto; any person skilled in the art is within the technical scope of the present disclosure; the technical scheme and the improved concept of the invention are equally replaced or changed; are intended to be covered by the scope of the present invention.
