Notification number is CN2416900, its day for announcing is that the Chinese utility model patent in January 31 calendar year 2001 discloses a kind of treatment gynaecopathia topical delayed release device, comprise the ring body of being made by elastomeric material, ring body contains active pharmaceutical ingredient, i.e. danazol or estriol.Ring body structurc comprises: the homogenizing ring of pastille, liner be the cyclome and the recessed ring of periphery of cyclome, the liner drug-containing core ring of pastille skeleton core ring not, and the elastomeric material of making ring body is silicone rubber or polyurethane elastomer.This device cooperation is administered for the treatment gynaecopathia.

At present, along with the continuous development of medical level, need a kind of a kind of medication device that not only can be used for contraception of woman but also can be used for the treatment of female diseases especially.

The utility model content

At above-mentioned prior art, this utility model provides a kind of in utero medicament slow release device, just can realize making this device not only can be used for contraception of woman but also can be used for the treatment of female diseases by place different medicines in this device.

In order to solve the problems of the technologies described above, this utility model in utero technical scheme that is achieved of medicament slow release device is: comprise three long-armed, adjacent in twos be 90 ° to 180 ° angles between long-armed, wherein one to three long-armed be hollow structure, the long-armed of each hollow structure is cylindric, the barrel of its cylinder is a mesh shape, and one of them long-armed end is provided with through hole.

This utility model is the medicament slow release device in utero, is provided with the drug release body in described hollow structure long-armed.Described three long-armed layouts are T type or Y type.Be positioned at two adjacent long-armed impressions that are provided with on T type or Y type top, it is be positioned at T type or Y type bottom long-armed that the end is provided with the long-armed of through hole.Two adjacent long-armed end profile that are positioned at T type or Y type top are made of curved surface.

Compared with prior art, this utility model in utero the beneficial effect of medicament slow release device be:

Because three long-armed is to be designed to layout to be T type or Y type, can guarantee that this device is stabilized in utero, can not twist owing to the displacement of human body or come off, have at least one to be the network that has hollow during three of this device are long-armed, specifically selecting for use is several long-armed hollow structures that are, can discharge identical medicine according to not being both of the purpose of placing medicine, still need discharge different medicines and determine.

Description of drawings

Fig. 1 is an in utero medicament slow release device front view of this utility model;

Fig. 2 is an in utero medicament slow release device vertical view shown in Figure 1;

Fig. 3 closes up view before device shown in Figure 1 is placed.

The specific embodiment

Below in conjunction with the drawings and specific embodiments this utility model is done to describe in further detail.

This utility model main parts size and specification specified: 1. long-armed, 2. long-armed end, 3. hollow structure, 4. grid, 5. through hole.

As depicted in figs. 1 and 2, this utility model in utero structure of medicament slow release device is: comprise three long-armed 1, described three long-armed 1 layout is T type or Y type, be 90 ° to 180 ° angles between adjacent in twos long-armed 1, wherein one to three long-armed 1 is hollow structure 3, long-armed 1 of each hollow structure 3 is cylindric, the barrel of its cylinder is grid 4 shapes, one of them end of long-armed 1 is provided with the through hole 5 that is used for threading, this through hole 5 is arranged on the long-armed end that is positioned at T type or Y type bottom, have hollow structure 3 long-armed 1 in be provided with the drug release body.In the time of this device need being placed into the receptor uterine cavity, as shown in Figure 3, after device two long-armed 1 of the top closed up, the device that will have medicine with specific purpose tool passes cervix uteri by vagina and is placed in the cavity of uterus, for fear of in put procedure because the corner angle on the device can bring unnecessary misery to receptor to the stimulation that vagina or cervix uteri produce, preferably will be positioned at long-armed 1 adjacent end 2 of T type or Y type top two is made of the curved surface of slyness, in addition, in order to guarantee to be positioned at adjacent long-armed 1 not only the closing up conveniently of T type or Y type top two, and when after being placed into uterine cavity, withdrawing from specific purpose tool, two the long-armed 1 T type that is bent into or the Y types that can rely on elastic properties of materials interaction energy nature of this device top preferably are provided with impression at these two on long-armed.
