Abstract
The application discloses a medicine-distribution type uterus stent, comprising a stent with a bionic structure having an inner cavity and an external shape matched with a uterus, and a balloon arranged in the inner cavity. When the balloon is inflated to be full, the balloon supports and holds the bionic form of the stent so as to achieve the purposes of stopping blooding of the uterus by compressing and preventing intrauterine adhesion by completely and physically isolating; before the balloon is inflated to be full, liquid or gelatinous medicine is sent to the inner cavity of the stent through a medicine feed tube, and filling liquid is delivered through a filling tube to fill the balloon; the stent is provided with medicine distributing holes, so that when the balloon is gradually inflated, the balloon like a propeller of a syringe extrudes the medicine in the inner cavity to reach affected parts of a patient through the medicine distributing holes; the balloon in fully inflated state has the shape matched with the inner cavity of the stent body, so that the balloon can completely extrude the medicine out of the inner cavity of the stent to the affected parts through the medicine distributing holes; According to the scheme, no medicine is residual.
Description
Technical field
The application belongs to technical field of medical instruments, specifically, relates to a kind of for preventing the cloth Types of Medicine uterus support of intrauterine adhesion.
Background technology
Intrauterine adhesion is the focus of clinic study in recent years, and in the middle of postoperative complication of artificial abortion, intrauterine adhesion accounting is larger, and artificial abortion posterior synechiae more and more obtains the attention of medical circle.
Due to adhesion position and degree varies, the Symptoms of intrauterine adhesion is also slightly different, but cardinal symptom is artificial abortion repeatedly, or after the dilatation and curettage, occurs that amenorrhea is with periodic abdominalgia, hypomenorrhea, and infertility etc.
(1), amenorrhea (or hypomenorrhea): the complete adhesion person of uterine cavity, can there is amenorrhea, amenorrhea is chronic.The adhesion of uterine cavity part and inner membrance partial destruction person, show as hypomenorrhea.
(2), periodic abdominalgia: generally after artificial abortion or the dilatation and curettage about one month, there is sudden lower abdomen spasmic pain, wherein have over half with rectal tenesmus sense; Some patient suffers from abdominal pain acutely, uneasy in either sitting or lying, and moving difficulty, even connects toilet and all likely produces violent pain.Pain generally continues to alleviate gradually, disappear after 3 to 7 days, and interval is about one month, and generating period is suffered from abdominal pain again, and gradual increasing the weight of.
(3), easily there is secondary infertility after infertile and habitual abortion, premature labor metrosynizesis, even if habitual abortion and premature labor also easily occur in pregnancy.Due to metrosynizesis, inner membrance damages, and uterine volume reduces, and affect the normal implantation of embryo, and affects fetus and in uterine cavity, survive extremely mature.
About the method for preventing and treating of intrauterine adhesion, research is more active both at home and abroad, wherein there are early stage placement intrauterine device, isolation diaphragm, uterus support, in utero administration, use adherence preventing material etc., these measures have all obtained certain effect, but still undesirable in clinical use, to exist in prior art defect following points:
(1), because uterus is not the spherical of standard, the uterus support of balloon structure of the prior art, can not support the shape in uterus completely, causes the phenomenon of locating still easily to stick together at angle, palace etc.;
(2), the shape in uterus is a cavity, the support of the uterus shape contraceptive ring of prior art and thin film composition, can not support the cavity in uterus fully, causes in the uterus of uterine cavity shaped de-vice edge and easily sticks together;
(3), existing administering mode is generally in intrauterine one end, directly to offer dosing holes at delivery tube, this administering mode is only suitable for feeding liquid medicinal liquid, be not suitable for and feed gel medicine, can not be for the intrauterine position administration that easily sticks together, medicine has necessarily residual in delivery tube, causes waste.
Summary of the invention
The application has overcome above-mentioned shortcoming of the prior art, a kind of cloth Types of Medicine uterus support is provided, it has abundant cooperation uterus shape, physical isolation comprehensively, prevention metrosynizesis, be applicable to feed liquid and gel medicine, and can be for intrauterine easily stick together position administration, the physical isolation that its prevent and intervene that is a kind of intrauterine adhesion problem producing for uteroventral operations such as artificial abortion is carried out provides and the carrier utensil that promotes the scheme implementation of endometrium healing.
In order to solve the problems of the technologies described above, the application is achieved through the following technical solutions:
A kind of cloth Types of Medicine uterus support, comprise rack body, described rack body is the biomimetic features that external shape and uterus adapt, in described rack body, have internal cavities, in described internal cavities, be provided with sacculus, described sacculus is under full state, adapt with the shape of the internal cavities of described rack body, described sacculus is connected with and is full of pipe, and described internal cavities is connected with delivery tube, and described rack body is provided with the cloth medicine hole being communicated with described internal cavities.
Further, be full of pipe and be connected with injection valve away from one end of described rack body, described delivery tube is connected with administration valve away from one end of described rack body.
Further, the injection valve that injection valve is one-way check, the administration valve that described administration valve is one-way check.
Further, the outside of injection valve and described administration valve is equipped with protective cover.
Preferably, injection pipe and described delivery tube are one-body molded.
Further, sacculus is the soft sacculus with high strength, high expansion coefficient.
Preferably, sacculus is latex balloon.
Preferably, rack body is silica gel support body.
Preferably, be arranged in described rack body cloth medicine hole unequal interval.
Preferred, the aperture in cloth medicine hole is identical.
Compared with prior art, the application's beneficial effect is:
A kind of cloth Types of Medicine uterus support described in the application, employing has internal cavities, and the support of the biomimetic features that external shape and uterus adapt and be arranged at the sacculus in its internal cavities, under sacculus full state, support and keep the bionical form of support, to reach compressing uterine hemostasis, comprehensively physical isolation, prevents the effect of intrauterine adhesion, before sacculus underfill, liquid or gelatinous medicine are sent into by delivery tube in the internal cavities of support, then by injection, manage and carry injection liquid that sacculus is full of, owing to being also provided with cloth medicine hole on support, therefore in the process expanding gradually at sacculus, sacculus is as the propeller of syringe, medicine in extruding internal cavities makes it pass through cloth medicine hole arrival patient's affected part, because sacculus is under the state being full of, to adapt with the shape of the internal cavities of rack body, therefore, sacculus can all squeeze out arrival affected part, cloth medicine hole from the internal cavities of support by medicine, therefore, this scheme can accomplish that medicine is not residual, prevent drug waste, because support is the biomimetic features with internal cavities, and coordinate the progradation of sacculus to carry out administration, cloth medicine hole can be set at the position that easily sticks together, make the medicine affected part of going directly, determined curative effect, after administration, sacculus remains full of state, can prevent that medicine is back in the internal cavities of support, make medicine long duration of action in affected part, and can multiple dosing, the administration that until uterus wound healing, that the application is applicable to is liquid, be particularly useful for gel medicine.
