Background

Pelvic effusion is a manifestation rather than a disease, and is exactly a description of pelvic fluid by imaging, which can be divided into physiological pelvic effusion and pathological pelvic effusion, and part of normal women have a small amount of pelvic effusion in menstrual period or ovulation period. This is because when there is a small amount of exudate, leakage or rupture bleeding in the visceral organs of the pelvic cavity, the fluid will accumulate in the pelvic cavity first, thus forming a pelvic effusion. For example, during menstruation, a small amount of menstrual blood flows back to the pelvic cavity to cause pelvic effusion; accumulation of follicular fluid in the pelvic cavity during mid-menstrual ovulation can also lead to pelvic effusion; for patients with constipation, the intestinal peristalsis is abnormal, which can cause a small amount of intestinal juice to seep out to cause pelvic cavity hydrops.

Physiological pelvic effusion does not need special treatment, and a small amount of pelvic effusion can be automatically absorbed. In the case of pelvic inflammation or neoplastic effusion, the effusion quantity is over 100 ml, and targeted treatment is required according to etiology.

Pathological pelvic cavity hydrops need use corresponding extraction element to extract the hydrops, and current pelvic cavity extraction element is when extracting the hydrops, and when inserting the vagina through will extracting needle body etc. during, it must can cause the muscle arm of vagina to appear the twitch situation to can cause the difficulty that is difficult to carry out the hydrops extraction, and current extraction element is not convenient for carry out the direction position adjustment after inserting, thereby the medical personnel of being not convenient for operate the adjustment.

9. A use method of a pelvic cavity effusion extraction device is characterized by comprising the following use steps:

the method comprises the following steps: when the vaginal dilator is used, the vaginal dilator (100) is inserted into a vagina, so that the vaginal dilator (100) can expand the vaginal opening to a certain degree, the position of the catheter (501) can be adjusted conveniently, the shaft cylinder (204) can rotate through the adjusting column (300), the rotating columns (201) at the two ends of the shaft cylinder (204) can rotate between the two bearing blocks (101), and the C-shaped vaginal dilator (100) can be adjusted to a certain direction, so that the direction of the adjusting column (300) can be adjusted, the direction of the catheter (501) can be adjusted when the catheter (501) is inserted, and the catheter (501) can reach the position of the pelvic cavity conveniently;

step two: then the adjusting column (300) can be slid, so that the two sliding grooves (301) on the adjusting column can slide on the two limiting columns (205), the sliding direction of the adjusting column (300) can be limited, the position of the inserted liquid suction catheter (501) can be adjusted conveniently, and medical staff can adjust the positions of the adjusting column (300) and the liquid suction catheter (501) conveniently under the searchlighting of B-ultrasonic instruments and other instruments;

step three: then, the inflating ball (401) needs to be pinched by hand, the annular column (403) can be ventilated through the hose (402), the first air bag (405) at one end of the annular column can be inflated through the two first communication pipes (404), and then air can be pressurized into the first air bag (405) through the ventilating column (406), so that the first air bags (405) can be swelled, the first air bags (405) in the swelled state can be abutted against the inner wall of the bearing block (101) in the vagina expanding column (100), and the first air bags (405) and the outer walls at two sides of one end of the rotating column (201) are wrapped, so that fillers are abutted against between the rotating column (201) and the bearing block (101), so that the two rotating columns (201) can be limited to rotate, the shaft barrel (204) can not rotate, and the adjusting column (300) and the catheter (501) are difficult to rotate;

step four: meanwhile, the communicating pipe II (407) in the positioning mechanism (400) can inflate the air bags II (408) on the two sides, so that the air bags II (408) in an inflated state can be abutted against the outer wall of the adjusting column (300), fillers are arranged between the two symmetrical sides of the adjusting column (300) and the shaft barrel (204) for abutting against each other, the adjusting column (300) can be limited to slide, the extracting catheter (501) can be prevented from being influenced when muscles twitch during extracting operation, and accordingly effusion extracting can be facilitated;

step five: the threaded rod (505) can be driven to rotate by the rotating handle (506) in the liquid pumping mechanism (500), so that the piston block (504) can slowly move in the liquid pumping column (503), and the liquid pumping needle head (502) at the end part of the catheter (501) can slowly pump pelvic effusion, thereby preventing overlarge pumping action and redundant air from being pumped in the pumped object.
