Abstract
An intrauterine device comprises a strip (1), a rod (2)interconnected with the strip (1)to form a t-shaped element therewith, a coil (3)fitted over the rod (2), and a thread (4)for dynamic monitoring of the iud while in the uterine cavity, connected to the rod (2); the coil (3)has at least two layers (5,6)of which the first layer (5)is made of an elastic polymer material, serves as a base and faces directly the rod (2), while the second layer (6)is made in metal.
Description
Technical Field
The present invention relates generally to contraceptives and more specifically to intrauterine devices (IUD).
Background-Art
Known in the art is an intrauterine device (US,· A, 4,198,966), comprising a strip, a rod carrying a copper coil and interconnected with the rod to form a T-shaped element therewith, and a dynamic monitoring thread attached to the rod.
The coil of the known device is made of a copper wire featuring high degree of purity, i.e., from chemically pure t .
copper, which adds to the weight of the entire device and <
to the danger of expulsion. The copper coil is liable to
AP 0 0 0 0 5 1 gradually dissolve in the course of a prolonged exploitation and finally to break, thus forming sharp sticking out ends which inflicts injury upon the uterine walls and causes bleeding.
Also known in the art is an intrauterine device Nova T Cu 200 Ay (Huhtamaki Co., Leiras, Finland) comprising a strip, a rod connected to the strip to form a T-shaped element, a coil from silver-based copper wire mounted on the rod, and a thread for dynamic monitoring of tne IUD while in the uterine cavity, fixed at the rod en<J.
The aforesaid known device is characterized, by the fact that the coil made from silver-based copper uvire adds to the weight of the entire device, thus enhancing the dangBAD ORIGINAL $ er of expulsion.
Summary of the Invention
It io a primary and essential ooject of tac invention to provide an intrauterine device cuich is less liable to expulsion in the course of operation due to improvements in the coil taereof.
§aid object is accomplished due to the fact that in an intrauterine device, comprising a strip, a rod connected to the strip to form a T-shaped element therewith, a coil mounted on tac rod, and a thread for dynamic monitoring of the intrauterine device while in the uterine cavity, connected to the rod, according to the invention, the coil is composed of at least two layers, the first layer be in.o made of an elastic polymer material serving as ε base and faces directly the rod, while the second layer is made of metal.
It is expedient that the coil of the intrauterine device of the invention have a third layer made of metal and located on the first layer so as to face the rod.
It is also expedient that in the intrauterine device of tne invention the coil have two lateral layers each made of metal and located on the first layer.
It is likewise expedient that in the intrauterine device of the invention the base of tide coil be holla., for performing complex contraception.
Thus, provision of the coil base made from an elastic polymer material in hll the embodiments mentioned above render the entire device light in weight and ensures
BAD ORIGINAL arainst breaking of the coil upon complete dissolution of its metallic layers, thereby making the coil fully atraumatic .
Brief Description of the Drawings
In what follows the invention will become^ more apparent from a consideration of some specific embodiments thereof witn reference to the accompanying drawings, wherein :
FIG. 1 a general schematic view of an intrauterine device, according to the inventionj and
FIG. 2 through FIG. 6 depict sectional views of the various coil embodiments, according to the invention.
Best Llode for Carrying Out the Invention
The intrauterine device, (FIG. 1) comprises a strip χ a rod 2 interconnected with the strip 1 to form a Tshaped element therewith, a coil J mounted on the rod 2, and a thread 4 for dynamic monitoring of the IUD while in the uterine cavity, connected to the rod.
Given below are some specific embodiments of the herein-disclosed intrauterine device featuring the various constructional arrangements of the coil.
The coil 3 is constituted by two layers (FIG. 2), a first layer 3 being made of an elastic polymer material, serves as the base and faces directly the rod 2 (FIG. 1>, while a second layer 6 (FIG. 2) is made in metal. In addition, the coil 3 (FIG. 1) has a third layer 7 (FIG. 3) made also in metal and located on the first layer 5 so as to face the rod 2 (FIG. 1). The coil 3 has two lateral
BAD ORIGINAL layers c, 9 (FIGS 4, 5) each made in metal and located on the first layer 5· The first layer 5 which serves as a ease, is made hollo;, for use of complex contraception.
In all the emoociments mentioned above the metallic layers applied to the base are made of, e.g., copper, silver, or nickel. .,
Tue intrauterine device of the invention operates as follows.
The IUD that has preliminarily been arranged in a straight line by bringing the strip 1 in alignment with the rod 2, together with the coil 3 and the dynamic monitoring tnread 4-, is fitted into a special syringe (not saown in the drawings). Then the IUD is inserted, with the aid of the syringe, directly into the uterine cavity, wherein the device assumes the position that suits the snape of the uterine cavity. When in the uterine cavity the device is pressed by the strip 1 against the uterine wall, while the free ends of the dynamic monitoring thread 4 emerge from the uterine cervix.
Tue metallic layers ofyfche coil 3 are liable to gradually dissolve in the course of the IUD operation, but upon their complete dissolution the coil base m&de of an elastic polymer material does not break, which rules out perforation of the uterine walls causative of bleeding.-nd reduces the danger of traumatic lesion. In addition, use of a coil provided with an elastic base and metallic layers applied thereto as described above, in the, described above IUD reduces the weight of the entire device and hence bad original $ renders the danger of expulsion and traumatism less possible .
Industrial Applicability
Tne invention can find application in gynecological practice for prevention of an undesirable pregnancy, as well as a preventive measure aimed birth control and family planning.
