Obstetrics and gynecology hemostatic bag

Abstract

The invention discloses an obstetrics and gynecology hemostatic sac, which belongs to the field of medical devices and includes a uterine cavity sac, a vaginal sac, an air tube, a sewage pipe, a drug delivery tube, an inflatable air bag and a drug injector. Membrane 1 and capsule 2, capsule 2 is provided with a plurality of diversion grooves connecting the front and rear ends of the uterine cavity capsule, and a row of elastic curved rods with increasing elastic modulus from the front end of the uterine cavity capsule to the rear end are arranged in the diversion grooves ; The bottom of the diversion groove and the outer surface of the second capsule are evenly distributed with drug-passing micropores, and the first capsule is evenly provided with a plurality of strip holes parallel to the diversion groove along its circumference; The sewage pipe is connected, the vaginal capsule is set on the sewage pipe, and the sewage pipe is provided with a diversion port between the uterine cavity capsule and the vaginal capsule. The present invention has relatively clear and simple export control of dirt, can realize relatively complete sealing and discharge of dirt; can prevent dirt from infiltrating into the administration cavity before inflation, and is beneficial to ensure the hemostatic function of the drug.

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
