Description
Technical Field
The utility model relates to the technical field of hysteroscope filters, in particular to a hysteroscope filter capable of preventing air bubble embolism.
Background
Hysteroscopic surgery is an endoscope technology which is simple in operation, visual, reliable and high in safety, is an important diagnosis and treatment means for intrauterine lesions, is a new technology for recent gynecological development, and has complications along with the widening of operation indications, while serious air embolism is a rare but fatal complication in hysteroscopic surgery. The disease is sudden, the development is rapid, and the fatal consequences are always generated, so that the high importance is worthy of being brought.
The incidence of air embolism of the hysteroscope is 0.06%. The surface of the womb wound has broken vein blood vessels and increased intrauterine pressure, and the head is often taken down and the hip is high when the gynecological operation is performed, and the heart is lower than the level of the womb. Lowering uterine venous pressure; when the uterus expanding medium is injected, an obvious pressure difference exists between the uterine cavity and the central circulation, and if the uterus expanding liquid is not replaced in time at the moment, the uterus expanding instrument directly presses air into the uterine cavity, so that the air enters the human blood circulation. After the air enters the right heart, the air and the blood in the heart chamber are stirred to form a large amount of foam due to the heart beating. The pulmonary artery pressure is increased due to the obstruction of blood flow, and the end-expiratory C02 pressure is reduced, so that severe cardiogenic shock is caused; air enters the pulmonary circulation, blocking the main passage of pulmonary arteries, and emboli from the lungs block the cerebral vessels, thereby causing emboli in the brain and other organs.
At present, uterus expanding devices are generally used clinically, and a double-bottle type transfusion system is adopted. A connecting pipe is adopted between the two bottles, one bottle is connected with the uterus swelling instrument through a one-way vent pipe, and the other bottle is connected with the water inlet of the hysteroscope. Pre-filling before operation, connecting a double-bottle type transfusion system, adjusting the uterine expansion pressure, connecting a hysteroscope, and evacuating air in the skin tube before operation. During operation, a nurse closely monitors the amount of the uterine distention medium, and the uterine distention medium is replaced in time before a bottle of uterine fluid is completely transfused, so that air embolism caused by air entering the uterine cavity is prevented.
The prior art has the following defects: the infusion bottle lacks filter equipment, can't thoroughly prevent that air gets into the palace chamber and causes the bubble to appear in the hysteroscope, takes place the air embolism, and secondly, the liquid in the infusion gets into the palace chamber, and liquid probably contains impurity and is not removed, still can take place to suck backwards. Therefore, we improve the above and provide a hysteroscope filter capable of preventing air bubble embolism.
