Hemostatic bag for obstetrics and gynecology department
Technical Field
The invention relates to the field of medical instruments, in particular to a hemostatic bag for obstetrics and gynecology department.
Background
In clinical obstetrics and gynecology, postpartum hemorrhage is the most common complication, and postpartum hemorrhage is defined as the hemorrhage after childbirth, where hemodynamics are unstable. At present, the commonly used treatment methods are uterine cavity yarn filling and uterine cavity water sac yarn filling, wherein the time consumption of the uterine cavity yarn filling process is long, the pain stimulation to a puerpera is heavy, a patient is difficult to bear in a non-anesthesia state, and the process of filling the uterine cavity yarn cannot avoid yarn pollution, so that the risk of uterine cavity infection is greatly increased. Because the postpartum cervix is loose, the water sac in the uterine cavity easily slides out, so that the compression hemostasis fails, the water sac expands uniformly, uniform pressure is generated towards the periphery, the dirt remained in the uterine cavity can not be well discharged through the cervical orifice in a directional manner, and the pressure impact force generated by the too fast increase of the pressure can cause the residue to be extruded into the fallopian tube at the lower part of the uterine cavity, so that the potential hazard is brought to the subsequent recovery.
The utility model discloses a in the patent of grant bulletin No. CN 206745409U, it includes palace chamber utricule, bracing piece, vagina utricule, upper end of the support bar is located to palace chamber utricule, and palace chamber utricule evenly is equipped with a plurality of medicine holes of scribbling including interior utricule and outside parcel for the medicine layer on the medicine layer, is equipped with the drainage chamber that runs through the bracing piece both ends in the bracing piece, is equipped with the water cavity of giving and the chamber of dosing of utricule and medicine layer in the intercommunication respectively in the bracing piece, sets up the connecting pipe outside the bracing piece, and the connecting pipe upper end is equipped with the vagina utricul. It can avoid the uterine cavity sac body from being polluted when passing through the vagina; the hemostasis by compression is performed while the hemostasis by drugs is performed; the dirt remained in the uterine cavity can be completely discharged; can also avoid extruding the uterine cavity sac body under the action of uterine contraction force. However, it has the following disadvantages: in the expansion process of the uterine cavity utricule, the residual dirt in the uterine cavity is pushed to the upper end and the lower end of the uterine cavity and is led out through the two drainage cavity pipes respectively, although the dirt is discharged completely, the leading-out control is complicated, the leading-out control process of the residual dirt pushed to the lower end of the uterine cavity is unclear, the residual dirt is led out only through one drainage pipe arranged on one side of the vaginal utricule, the vaginal utricule is easy to pollute, and the sickbed is polluted due to the possibility of leakage in the taking-out process of the device; the drug coating hole is always directly communicated with the drug administration cavity, and the residual dirt in the uterine cavity can more permeate into the drug administration cavity, thereby causing the drug pollution and reducing the hemostatic function of the drug.
