The utility model content
For solving the problems of the technologies described above, this utility model provides a kind of deformability stronger, uses more for convenience, and comfort is a kind of r type shape memory nano plastic intrauterine device preferably.
A kind of r type shape memory nano plastic intrauterine device of the present utility model, comprise support and active matter carrier block, described support comprises trailing arm, transverse arm and arched arm, described transverse arm comprises the first transverse arm and the second transverse arm, described arched arm comprises the first arched arm and the second arched arm, described the first transverse arm is fixedly mounted on the top of described trailing arm by described the first arched arm, described the second transverse arm is fixedly mounted on the top of described trailing arm by described the second arched arm, described the first transverse arm, the first arched arm and trailing arm connect into the r type, described the second transverse arm, the second arched arm and trailing arm connect into the r type, described active matter carrier block is arranged on described trailing arm and/or transverse arm, described support is the shape memory plastic support.
Further, described trailing arm, transverse arm and arched arm are structure as a whole, and described the first transverse arm and the second transverse arm are point-blank.
Further, on described the first transverse arm, also be fixedly connected with the 3rd arched arm, on described the second transverse arm, also be fixedly connected with the 4th arched arm, the top of described the 3rd arched arm and the 4th arched arm is to the bending of trailing arm direction.
Further, described active matter carrier block comprises columned copper main body, and the lateral surface of described copper main body is coated with the active matter layer.
Further, the bottom of described trailing arm is provided with annular tailfiber.
Compared with prior art the beneficial effects of the utility model are: support comprises trailing arm, transverse arm and arched arm, transverse arm comprises the first transverse arm and the second transverse arm, arched arm comprises the first arched arm and the second arched arm, the first transverse arm is fixedly mounted on the top of trailing arm by the first arched arm, the second transverse arm is fixedly mounted on the top of trailing arm by the second arched arm, the first transverse arm, the first arched arm and trailing arm connect into the r type, the second transverse arm, the second arched arm and trailing arm connect into the r type, the active matter carrier block is arranged on trailing arm and/or transverse arm, and support is the shape memory plastic support; The support of r type can be fixed on birth control apparatus in cavity of uterus preferably, and shape memory plastic is a kind of at room temperature fixedly deformation and long-term storage, when being warming up to certain during specified temp, can return to very soon the high molecule nano material of shape before distortion again; This birth control apparatus with shape memory plastic support, can be in inserting the operation process of birth control apparatus, make birth control apparatus resting period in sleeve pipe longer, have voluntarily the function of recovering, after inserting, can also prevent effectively that birth control apparatus from coming off in uterine cavity, corrosion and fracture, reduced risk, in addition, this birth control apparatus can also effectively adapt to different cavity of uterus, and the metal sense is less, and comfort is also better.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for this utility model is described, but are not used for limiting scope of the present utility model.
