Detailed Description
The present invention will be further explained with reference to the attached drawings.
A uterus support with shape memory function, including the non-enclosed type filler ring 1 that a compound area was made, filler ring 1 middle part is memory alloy skeleton 5, 2 cladding memory alloy skeletons of silicon rubber 5, memory alloy skeleton 5 has 3 flat memory alloy pieces to be longitudinal arrangement to constitute, sets up clearance L between per two flat memory alloy pieces1An opening 12 is formed in the circumference of the supporting ring 1, a pull rod 7 is vertically connected with the horizontal plane of the supporting ring 1, the outer end of the pull rod 7 is connected with a pull ring 8, and the pull rod 7 is located on one side of the opening 12.
The supporting ring of the utility model is a non-closed ring made of a composite band-shaped structure. The ring carrier in the structure radially supports intensity height, and axial strength is lower. The lower axial strength enables the supporting ring to be deformed by external force before entering a human body, the supporting ring is extremely easy to be sent into the human body, no damage is caused to human tissues, the supporting ring recovers the original shape after entering the human body, the radial deformation stretching force of the supporting ring can be provided under high radial strength, the supporting ring has stronger supporting strength in the human body, and the phenomenon that a user does not fall off during movement is ensured. Due to the flexibility of the silicon rubber, the memory alloy framework can not be rapidly heated in the pushing process under the condition that the pushing and pulling do not damage the soft tissue of the human body contacted with the supporting ring, and the temperature comfort of the patient using the uterine support is further ensured.
Opening on the trunnion ring in the structure, the easy compressive deformation's of trunnion ring characteristics have formed the combination of just right under the shape memory function that makes the uterus support and low temperature, under the condition in easily sending into the human body, can resume the ring shape of trunnion ring in the short time under the body temperature again, have reached the design purpose that makes the trunnion ring have higher radial support intensity and lower axial deformation intensity.
Pull rod and pull ring all adopt the silicon rubber materials of silicon rubber materials and memory alloy skeleton outsourcing cover in the structure, a compression molding.
The thickness of the memory alloy sheet of the utility model is 0.05-2.5mm, preferably 0.2-1.2mm, and the width is generally 3-10 mm.
The utility model discloses preferred scheme is: there are two inclined planes at opening 12, and the two inclined planes are parallel, namely: the first inclined plane 4 is parallel to the second inclined plane 3, and the included angle alpha between the first inclined plane 4 and the plane where the lower edge of the supporting ring is located is 20-35 degrees. The above structure is the preferred solution of the opening 12 of the present invention. The opening 12 of the ring, when stretched outwards, enables the ring to be pulled out of the body in an approximately elongated shape. Because the ring is in a composite belt shape after being straightened, two inclined planes are arranged at the opening 12. The structure of the opening 12 can lead the supporting ring to generate deformation in the process of pulling out the supporting ring from the body, and the opening distance at the opening 12 is gradually increased to lead the supporting ring to be deformed into a strip shape similar to an ellipse or a strip shape, thus leading the supporting ring to be conveniently pulled out of the body and injuring any human tissue in the process of pulling out the supporting ring from the body.
Distance L between two inclined planes at opening 122Is 0.01-5 mm, this distance being preferred. It is further preferred that the distance L between the two inclined surfaces at the opening 12 is2Is 0.2-2 mm, but of course this distance may also exceed 5 mm. The utility model discloses a these preferred schemes are the global design who combines with the global scheme, and it is more suitable for the pessary and frequently passes in and out the human body, under the prerequisite of easy operation, does not produce the damage to human tissue during the business turn over.
The distance L between the connecting part of the pull rod 7 and the supporting ring 1 and the opening 124Is 2-15 mm. Distance L between pull rod 7 and inclined plane at opening 124Further preferably 2-6 mm. The distance is easy to make the opening 12 gradually enlarged under the action of pulling force, so that the supporting ring is approximately in a long strip shape after being deformed from a circular shape.
The cross section of the 3 flat memory alloy sheets after longitudinal arrangement is oval. The 3 flat memory alloy pieces have different widths, the first flat memory alloy piece 9Width W1Width W of the third flat memory alloy sheet 113The same width W of the second flat memory alloy sheet 102Is larger than the width W of the first flat memory alloy sheet 911-5 mm. The further preferred scheme is as follows: width W of second flat memory alloy sheet 102Is larger than the width W of the first flat memory alloy sheet 91Is 2-3 mm. The cross section of the 3 flat memory alloy sheets after being longitudinally arranged is approximately elliptical so as to further enhance the supporting strength of the supporting ring.
The width of the upper surface and the width of the lower surface of the supporting ring 1 in the horizontal direction are the same, and the width H of the supporting ring is larger than the longitudinal thickness L of the supporting ring3For further increasing the radial support strength of the ring. The width H of the supporting ring is larger than the longitudinal thickness L of the supporting ring3The preferred design is that the width H of the supporting ring is 6-16 mm, and the longitudinal thickness L of the supporting ring3Is 3-6 mm.
The utility model discloses further preferred scheme is: the circumferential surface of the outer ring of the supporting ring 1 is provided with a first arc-shaped groove 6, and the circumferential surface of the inner ring of the supporting ring 1 is provided with a second arc-shaped groove 13. The utility model provides an aim at of this scheme reduces the internal stress of silica gel ring, better performance alloy material's temperature sensitive memory characteristic. The preferred scheme of the depth and the length of the arc-shaped groove is as follows: depth L of first arc groove 65Is 2-4 mm, length L6Is 3-7 mm, and the shape of the second arc-shaped groove 13 is the same as that of the first arc-shaped groove 6. The utility model provides an arc wall structure is in order to further reduce 1 axial strength of ring, and easily fix a position when making ring and human tissue contact, this scheme can reduce the internal stress intensity of silicon rubber ring, it is easy to make ring 1 warp more easily at low temperature to be convenient for, the operator of being convenient for presses the ring into the shape that wants, further improve the deformability of ring, further guarantee that the uterus holds in the palm frequent business turn over internal do not harm human tissue, still can increase maneuverability, and make the uterus hold in the palm the location firm, do not produce the displacement.
The composite belt of the utility model is a state of a framework formed by silicon rubber coated memory alloy sheets after being stretched under the action of external force.
