Hemostatic bag for obstetrics and gynecology department

Abstract

The invention discloses a hemostatic bag for the obstetrics and gynecology department and belongs to the field of medical instruments. The hemostatic bag comprises a uterine cavity bag body, a vaginalbag body, an inflation tube, a dirt discharging tube, a medicine feeding tube, an inflation airbag and a medicine injector, the outer side wall of a medicine feeding cavity comprises a first bag membrane and a second bag membrane, the second bag membrane is provided with a plurality of diversion grooves connected with the front and rear ends of the uterine cavity bag body, and each diversion groove is internally provided with a series of elastic curved rods whose elastic modulus increases from the front end to the rear end of the uterine cavity bag body; medicine passing micropores are uniformly distributed in the bottoms of the diversion grooves and the outer surface of the second bag membrane respectively, and a plurality of strip-shaped holes parallel to the diversion grooves are uniformly formed in the circumference of the first bag membrane; the rear end of the uterine cavity bag body is connected with the dirt discharging tube which is sleeved with the vaginal bag body, and thedirt discharging tube is provided with a diversion port between the uterine cavity bag body and the vaginal bag body. According to the hemostatic bag, control over discharge of dirt is relatively clear and simple, and closed discharge of the dirt can be achieved completely; the dirt can be prevented from infiltrating into a medicine feeding cavity before inflation, and convenience is provided forensuring a hemostatic function of medicine.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an obstetrics and gynecology hemostatic bag. Background technique [0002] In clinical obstetrics and gynecology, postpartum hemorrhage is the most common complication, and any hemodynamic instability after delivery is defined as postpartum hemorrhage. At present, the commonly used treatment methods are uterine cavity gauze filling and uterine cavity water bag filling. The process of uterine cavity filling takes a long time, and the pain stimulation to the parturient is severe. It is difficult for patients to bear it under non-anesthesia state, and vaginal packing The procedure cannot avoid gauze contamination, which greatly increases the risk of intrauterine infection. Due to the relaxation of the cervix after delivery, the water sac in the uterine cavity is easy to slip out, resulting in the failure of compression and hemostasis, and the expansion of the water sac is uniform, an...

Problems solved by technology

But it has the following disadvantages: during the expansion process of the uterine cavity capsule, the dirt remaining in the uterine cavity is pushed to the upper and lower ends of the uterine cavity, and is exported through two drainage tubes respectively. Although the dirt is discharged relatively completely, the The export control is relatively complicated, and the export control process of the residual dirt pushed to the lower end of the uterine cavity is not clear. It is only drawn out through a drainage tube located on one side of the vaginal capsule, which is easy to contaminate the vaginal capsule. During the removal process of the device, it may External leakage leads to contamination of the hospital bed; the drug application hole is always directly connected to the drug delivery cavity, and the residual dirt in the uterine cavity may seep into the drug delivery cavity, resulting in contamination of the drug and reducing the hemostatic function of the drug
