Description
Technical Field
The invention belongs to the technical field of auxiliary medical instruments, and particularly relates to a negative pressure uterine cavity hemostasis device and a using method thereof.
Background
Postpartum hemorrhage is a serious complication of obstetrics and is one of the main causes of death of pregnant and lying-in women. The most common reason for postpartum hemorrhage is uterine hypodynamia, and the uterus needs to be resected by an emergency operation under the condition that the conventional conservative hemostasis is ineffective, so that the organs of a patient are deficient and the patient is regrettable to be infertile for the whole life. In recent years, uterine cavity balloon compression is gradually an alternative solution for treating postpartum hemorrhage, and water is injected into the balloon to enable the balloon to be continuously expanded so as to form a compression effect on blood vessels at a bleeding part, so that a hemostatic function is realized.
At present, the postpartum hemorrhage caused by uterine contraction and hypodynamia is clinically cured by filling a water sac or a uterine sliver for stopping blood in a uterine cavity to stop bleeding by compression. When major bleeding occurs, the hemostatic water sac is put into the uterus through the vagina to avoid contacting the vaginal wall, and after the uterine cavity water sac reaches the uterine bottom, 400 plus 800ml of water is injected into the uterine cavity water sac by an injector, so that the water sac is full to play a role in hemostasis. However, the existing uterine cavity compression balloon device has the following disadvantages: (1) because the volume of the postpartum uterus is indefinite and the shape of the uterine cavity is irregular, the water injection amount of the water sac is difficult to accurately quantify so as to achieve the optimal fit with the wound surface of the uterus, thereby being difficult to exert the optimal hemostatic effect; (2) postpartum uterine contraction weakness is usually manifested as poor uterine lower segment contraction, and the existing hemostatic sac cannot locally compress the poor uterine lower segment local contraction, so that the compression hemostatic effect on the uterine lower segment is poor; (3) for the cases of serious uterine contraction and large uterine cavity volume, a large amount of liquid (about 1000 ml) needs to be injected into the saccule to press the uterine wall, but the large-volume saccule can prevent the effective contraction and involution of the uterus, thereby causing clinical doubt; (4) after the conventional water sac is placed, the position of the water sac is moved downwards after being pressed due to uterine contraction, and even falls out of the uterine cavity. Based on the above, the invention provides a negative pressure hemostatic device for uterine cavity to solve the above problems.
