Description

Intrauterine liquid collecting device

Technical Field

The utility model relates to the technical field of medical equipment, in particular to intrauterine liquid collecting equipment.

Background

The fluids that are required to be expelled in the uterus of women generally contain blood and amniotic fluid. Blood includes intrauterine bleeding before, during and after gynecological surgery or before and after vaginal delivery, and also includes menstrual bleeding in women. Amniotic fluid is the fluid that flows out after rupture of the fetal membranes. Both of these fluids need to be removed from the body, and even collected, metered and analyzed to prevent occult bleeding, in order to develop a gynecological or obstetrical treatment regimen.

In the prior art, a chinese patent document with publication number CN106039432A and publication date 2016, 10, month 26 is proposed to solve the above-mentioned technical problems, and the technical scheme disclosed in the patent document is as follows: a blood collecting device comprises a vaginal bleeding collecting device, a catheter and a negative pressure container assembly, wherein the vaginal bleeding collecting device is placed in a human vagina and drains blood into the negative pressure container assembly through the catheter.

In the actual use process, the following problems can occur in the technical scheme:

(1) the collecting device is positioned in the vagina of a human body, although the collecting effect of partial liquid in the uterus can be completed, because an annular recess is formed between the cervix and the vagina, partial liquid can be deposited in the annular recess, namely the vagina fornix, the liquid cannot be discharged in time, potential safety hazards exist, the liquid output amount is different from an estimated value, the liquid output amount cannot be judged correctly, and the treatment and rescue time is delayed.

(2) The collected fluid does not identify intrauterine or vaginal bleeding and may mislead the medical personnel to make an incorrect treatment plan, with serious life-threatening consequences. If the bleeding of the vaginal wound is not sutured in time, the ligation is performed to stop bleeding, the bleeding is misjudged as the intrauterine bleeding, the contraction of the uterus is continuously strengthened, the vagina is not treated, the vaginal wound is continuously bled, and the treatment cannot be performed according to the cause.
