CN2478611Y - Active T-shape copper intrauterine device - Google Patents

Abstract

The utility model is composed of a longitudinal pole (3), two elastic beams (4) (5) on the pole (3), several turns of thin copper wires (2) on the pole (3), with a total surface area being 290-310mm<2>, and slow released carrier (1) for pain-killer and antibiotic medicine. This contraceptive device has the advantages of convenient placing and extraction, safety and excellent contraceptive rate, no damage, stimulation or side reaction.

Description

The copper intrauterine device of active T type

This utility model relates to and places the intrauterine contraceptive device of the women of child-bearing age.

In the prior art, female contraceptive agent (device) tool is various in style, but in clinical use, exist common issue with comprise: place with take out in operation inconvenient; Place the back and produce pain, amount of bleeding is big, side reaction is big, influences contraceptive effect; The long-pending size of copper containing surfaces is inaccurate, causes side reaction to increase or falls flat.

The purpose of this utility model is, designs the copper intrauterine device of a kind of active T type, have place with convenient to remove, can remove pain in using and prevent hemorrhagely, significantly reduce characteristics such as side reaction and contraceptive effect are good.

The technical solution of the utility model is, the copper intrauterine device of described active T type has vertical pole, its construction features is, it is arc structure and two elasticity transverse arms that are symmetrical in described vertical pole axis that there is its turning point this vertical pole upper end, the total surface that is wound with multiturn thin copper wire and described thin copper wire on the described vertical pole is 290～310mm2, on described vertical pole and elasticity transverse arm the anti-inflammation analgesic slow-released carrier is housed.

Make below in conjunction with accompanying drawing and to further specify.

Description of drawings:

Fig. 1 is the vertical sectional structure of this utility model;

Fig. 2 is respectively the anti-inflammation analgesic slow-released carrier that places two kinds of different embodiment stereochemical structures on the vertical pole (3) with Fig. 3.

In the accompanying drawings: 1-anti-inflammation analgesic slow-released carrier, 2-thin copper wire, 3-vertical pole, 4,5-elasticity transverse arm.

As shown in Figure 1, this utility model has vertical pole (3), its construction features is, it is arc structure and two the elasticity transverse arms (4) (5) that are symmetrical in described vertical pole (3) axis that there is its turning point this vertical pole (3) upper end, being wound with multiturn thin copper wire (2) and its total surface area on the vertical pole (3) is 290～310mm2, on vertical pole (3) and the elasticity transverse arm (4) (5) anti-inflammation analgesic slow-released carrier (1) is housed.

Described anti-inflammation analgesic slow-released carrier (1) can adopt the raw material of prior art and method to obtain.For example, it can in medical grade colloidal silicone rubber behind the corresponding anti-inflammation analgesic of mixing adding, make through sulfidization molding.Described anti-inflammation analgesic also adopts the related drugs of prior art, as uses commercially available " indometacin " medicine to be a kind of feasible example.

Design principle of the present utility model is, because elasticity transverse arm (4) (5) is an arc structure with the connecting portion of vertical pole (3) upper end, make described transverse arm (4) (5) have certain elasticity, the T type birth control apparatus that this structure is more traditional can significantly alleviate the stimulation to human body, and side effect and sense of discomfort are significantly reduced; Anti-inflammation analgesic slow-released carrier (1) in use can slowly discharge relative medicine (promptly having " activity "), removes pain thus, prevents hemorrhage and antiinflammatory, significantly reduces untoward reaction; Aspect copper wire surface area size definite, through clinical for many years actual exploration and summary, adopt the optimum surface area size about 300mm2, guaranteed burst size every day of copper ion like this, effectively stoped capacitation, realize best contraceptive effect.

As known from the above, this utility model is the copper intrauterine device of a kind of active T type, and it has places and convenient to remove and not damaged, non-stimulated, characteristics such as contraceptive effect is good.

Embodiment: vertical pole (3) and transverse arm (4) (5) are overall structure, adopt nontoxic polyethylene formation, wherein the diameter of vertical pole (3) and length are respectively 2mm and 34mm, transverse arm (4) (5) length is respectively about 16mm (containing the arc structure that radius is 4mm), and vertical pole (3) goes up around the copper wire of φ 0.4mm and to make total surface area be 300mm2.It is reached the contraception purpose in women of child-bearing age's uterine cavity.

Claims (1)

1, the copper intrauterine device of a kind of active T type, vertical pole (3) is arranged, it is characterized in that, it is arc structure and two the elasticity transverse arms (4) (5) that are symmetrical in described vertical pole (3) axis that there is its turning point this vertical pole (3) upper end, being wound with multiturn thin copper wire (2) and its total surface area on the vertical pole (3) is 290～310mm2, on vertical pole (3) and the elasticity transverse arm (4) (5) anti-inflammation analgesic slow-released carrier (1) is housed.
