Description

Hemostatic device for obstetrics and gynecology department

Technical Field

The utility model belongs to the technical field of medical appliances, and particularly relates to a hemostatic device for obstetrics and gynecology.

Background

The general bleeding after the gynaecology and obstetrics operation is a common clinical disease and frequently encountered disease, if the general bleeding is not controlled in time, the puerperal death can be caused, at present, the bleeding is controlled clinically mainly by using medicines to promote uterine contraction or filling gauze into uterine cavities and absorbent cotton, so that the operation is very troublesome, time-consuming and labor-consuming, and the great working difficulty is increased for medical staff. The irregular geometry of the filler is difficult to cling to the uterine wall, thereby being unfavorable for effective hemostasis. The hemostatic bag is a medical article, is applied to the condition of massive hemorrhage in the operation process, can endanger the life of a puerpera if the condition of massive hemorrhage occurs in the gynecological operation, can possibly cause the puerpera to be put in a very dangerous condition, and is an inflatable air bag from one aspect. Meanwhile, the existing hemostatic air bag is inconvenient to apply medicine to the uterus and discharge intrauterine waste liquid.

In view of this, patent grant publication No. CN11289090B proposes an intrauterine hemostat for obstetrics and gynecology, comprising a disposable hemostatic rod and an air intake device detachably connected to the disposable hemostatic rod; when not using, the negative magnet that is arranged in the elastic air bag can attract each other with the positive magnet that sets up in the casing, and then accomodate the elastic air bag in the recess of casing, accomodate simple structure, use the elastic air bag to realize stopping bleeding to the vagina inside, because hemostasis needs a period of time, so can separate disposable hemostasis stick with air inlet unit in hemostatic process, the cotton that absorbs blood of device can adsorb the filth in the vagina simultaneously, takes out it together when taking out disposable hemostasis stick, improved security performance. There is still room for improvement: because the hemostatic cotton of this device sets up in the casing, and area of contact with the uterus wall is little, so inhale blood less, can also use hemostatic medicine for hemostasis, accelerate hemostasis, use hemostatic medicine after, liquid medicine and hemorrhage all are liquid, and liquid can increase, can set up the hemostatic cotton outside the vaginal orifice, absorbs and blocks up the mixture of blood and liquid medicine.
