Abstract

The utility model discloses an intrauterine device having medicines, belonging to the human necessities class; the utility model is the general and effective contraceptive device for birth control, and comprises a bow and a bead string; the two arms of the bow is open and extended outwards, and the center is in complete pistil shape; the bead string connected with the bow is composed of a connecting string and a plurality of hollow copper beads. The utility model has the advantages that the intrauterine device is flexible and smooth, and conforms to the structural mechanics principle; the intrauterine device is uneasily fallen off from the uterine cavity, and can freely flex as the natural flexing degree of the uterus; the possibilities of injury and stimulation of the endometrium are reduced; the utility model also has the advantages of low cost, convenient operation, slow-release medicine and simple art.

Description

Intrauterine device having medicines

A kind of indometacin core pattern copper pearl intrauterine device that contains is a contraceptive device commonly used in the family planning work, effective, belongs to the human lives and needs class.

Laying intrauterine device is one of contraceptive device the most common in the family planning process, but normally used in the past intrauterine device has following comparatively obvious defects: (1) is on configuration, design in the past considers how intrauterine device carries because the factor of the external force that uterine contraction causes is too much, and ignore by changing the design of intrauterine device self structure, the characteristic that external force can be decomposed from the angle of structural mechanics, and the external form of intrauterine device is fixed and can't be adapted to the uterus curvature of different human body; (2) on material used, the pliability and the hot strength of materials such as Chang Yong plastics, silicone rubber or rustless steel were not good enough in the past, easily cause to uterine mucosa cause pain and hemorrhage than macrolesion, perhaps easily make iud expulsion and generation pregnancy with IUD in situ; (3) on structure connects, in the past the copper part of the copper intrauterine devices of Shi Yonging generally with copper wire twine, copper pipe overcoat or be connected with intrauterine device with modes such as copper powder and timbering material mixing, the copper surface is big and fixing with the uterine mucosa contact surface, and is higher to the local damage degree of uterine mucosa; (4) on the medication method, though the method for additional indometacin slow-released system on intrauterine device that adopted in recent years has certain effectiveness, but because intrauterine device and drug sustained release system are not once-formings, not only increased the difficulty of processing technology, and made former intrauterine device surface lose smoothness.In a word, since intrauterine device occurs, follow problems such as the expulsion of IUD, pregnancy with IUD in situ of existence, hemorrhage, pain and some other side effect, fail to obtain comparatively ideal solution always.

The purpose of this utility model is: a kind of indometacin core pattern copper pearl intrauterine device that contains practical, safe and reliable, rational in infrastructure is provided.

The indometacin core pattern copper pearl intrauterine device that contains described in the utility model mainly is made up of bow body and pearl line.Wherein: the bow body bends body, arc center bow body and pearl shape bow end by V-arrangement and forms, the middle-end of arc center bow body and V-arrangement bow body two arms is affixed, pearl shape bow end is fixed in the external top of stretching of V-arrangement bow, and whole bow body two arm openings stretch out, and the center is a complete flower core shaped; Bow system raw material and indomethacin powder when doing (trade name: indometacin) heat behind the mixing casting.The pearl line is made up of connecting line and move about hollow copper pearl and fixation hollow copper pearl, connecting line is with some move about hollow copper pearl and fixation hollow copper pearl series connection, one end of line is connected with the bottom of V-arrangement bow body, is fixed with connecting line to the outermost fixation hollow copper pearl of line other end direction.

The advantage that contains indometacin core pattern copper pearl intrauterine device described in the utility model is: the principle that the bow body pliability of intrauterine device is strong, meet structural mechanics, should not come off during use, and strengthened safety, reliability that intrauterine device uses; Intrauterine device smooth in appearance, and can bend the free flexing of degree naturally with the uterus of Different Individual significantly reduce the probability of uterine mucosa damaged and stimulation, and then has reduced because of damage and stimulate the pain that causes and hemorrhage; The slow releasing pharmaceutical of intrauterine device bow body contains the discomfort that indometacin core pattern copper pearl intrauterine device may cause to placement, and therapeutical effect is preferably also arranged; This intrauterine device has also that cost of manufacture is low, technology is simple and easy, places and takes out characteristics such as simple operation.

The utility model will be further described for the contrast accompanying drawing below:

Fig. 1 is the structural representation of this utility model embodiment.

Among the figure: 1. body is bent at the arc center; 2.V shape bow body; 3. pearl shape bow is held; 4. connecting line; 5. hollow copper pearl moves about; 6. fixation hollow copper pearl.

As shown in the figure, the bow body that contains indometacin core pattern copper pearl intrauterine device bends body (2), arc center bow body (1) and pearl shape bow by V-arrangement and holds (3) to form.Arc center bow body (1) is affixed with the middle-end of V-arrangement bow body (1) two arm, pearl shape bow end (3) is fixed in the overhanging top of V-arrangement bow body (2), whole bow body two arm openings stretch out, the center is a complete flower core shaped, when uterus contraction formation external force acts on the bow surface, V-arrangement bow body two arms stretch laterally by structural mechanics principle along continuous straight runs, prevent that effectively intrauterine device from skidding off from uterine cavity; When external force was removed, the bow body can restore to the original state again.The pearl line that contains indometacin core pattern copper pearl intrauterine device is made up of connecting line (4) and move about hollow copper pearl (5) and fixation hollow copper pearl (6), connecting line (4) hollow copper pearl (5) and fixation hollow copper pearl (6) series connection of will moving about, one end is connected with V-arrangement bow body (2), except that to line other end direction outermost fixation hollow copper pearl (6) is fixed with connecting line (4), other hollow copper pearl (5) that moves about all can move about on connecting line (4) flexibly; The pearl line has extremely strong adaptability for the different physiology curvatures in human body uterus, and shape can change arbitrarily with the curvature in uterus; Hollow copper pearl (5) can guarantee that copper body surface area increases and is beneficial to copper ion and discharge, and can reduce the contact area in copper body and uterus again and reduces its stimulation and damage to uterine mucosa.

Claims
