Referring to fig. 5, 6 and 7, the gynecological examination sampling device of the present invention has the following working principle:
firstly, a doctor holds the rear end of the outer cylinder of the sampling device with one hand, and inserts the front end of the sampling device into the body of a patient until the locating sleeve is contacted with the body of the patient;
then, the other hand of the doctor pushes the sliding blocks 201 on the two sides, and simultaneously observes the scale on one side of the sliding chute 101, after the sliding blocks 201 reach a proper position, the sliding blocks 201 on the two sides are stopped being pushed, the pressing parts 2031 of the elastic positioning parts 203 are pressed towards the axis of the outer cylinder by the forefinger and the thumb, so that the elastic positioning parts 203 on the two sides slide along the positioning sliding chutes 202 on the sliding blocks 201, the elastic positioning parts 203 slide until the supporting feet 2033 on the two sides leave the positioning sliding chutes 202 and are abutted against the two sides of the sliding chute 101 of the outer cylinder 1, the sliding blocks 201 can not slide forwards any more under the action of friction force, and the;
In the process that the inner cylinder 2 slides forwards relative to the outer cylinder 1, the volume of a sealed cavity formed between an inner cylinder end cover 6 at the bottom of the inner cylinder 2 and an outer cylinder end cover 5 of the outer cylinder 1 is gradually increased, the internal air pressure is gradually reduced, an air vent 305 arranged on a sampling pipe 302 is communicated with the sealed cavity, the air pressure in a sampling bag 301 communicated with the sampling pipe is reduced along with the air vent, and the sampling bag 301 is gradually contracted;
after the inner cylinder 2 is positioned along with the slide block positioning device 8, the rotating base 303 is held and starts to rotate, the outer cylinder end cover 5 in threaded connection with the inner wall of the outer cylinder 1 pushes the outer cylinder sealing sleeve 501 to move forwards, the sampling tube 302 fixedly and hermetically connected with the outer cylinder end cover 5 pushes the sampling capsule 301 to slide forwards along the axis of the inner cylinder, meanwhile, the volume of a sealing cavity formed between the inner cylinder end cover 6 at the bottom of the inner cylinder 2 and the outer cylinder end cover 5 of the outer cylinder 1 is gradually reduced, the internal air pressure is gradually increased, the air pressure in the sampling capsule 301 communicated with the sampling tube is increased, and the sampling capsule 301 is gradually expanded;
When the outer cylinder end cover 5 pushes the outer cylinder sealing sleeve 501 to move to contact with the inner cylinder end cover 6 at the bottom of the inner cylinder 2, the sampling bag 301 extends out from the front end outlet of the inner cylinder and expands to the maximum volume, the sampling soft bristles 304 arranged on the outer surface of the sampling bag 301 contact with the sampling part of a patient, after the outer cylinder is slightly rotated, the rotating base 303 is reversely rotated, the outer cylinder end cover 5 drives the outer cylinder sealing sleeve 501 to reversely move, the sampling tube 302 fixedly and hermetically connected with the outer cylinder end cover 5 pushes the sampling bag 301 to slide forwards along the axis of the inner cylinder, meanwhile, the volume of a sealing cavity formed between the inner cylinder end cover 6 at the bottom of the inner cylinder 2 and the outer cylinder end cover 5 of the outer cylinder 1 is gradually increased, the internal air pressure is gradually reduced, the air pressure in the sampling bag 301 is reduced along with the reduction, and the sampling bag 301 is gradually contracted until;
Pushing the pressing portion 2031 of the elastic positioning member 203 upwards to make the elastic positioning members 203 abutted against the two sides of the chute 101 of the outer barrel 1 leave the chute 101 and slide along the positioning chute 202 on the sliding block 201, and the two side supporting feet 2033 abut against the two sides of the positioning chute 202 respectively after the elastic positioning members 203 slide to the top end of the positioning chute 202; the sliding blocks 201 on the two sides are pushed to slide to the initial position of the sliding groove 101, and the inner cylinder 2 connected with the sliding blocks 201 slides to the inside of the outer cylinder 1;
Finally, the sampling device is withdrawn from the patient, and the physician pushes out the sampling capsule 301 by rotating the rotating base 303, and performs corresponding tests on the sample collected on the sampling capsule 301.
Before sampling, the sampling bag 301 is always in the inner cylinder 2 and cannot be contacted with the body of a patient, after sampling is completed, the sampling bag 301 is withdrawn into the inner cylinder 2 and then is drawn out of the body of the patient, and other parts in the body of the patient cannot be adhered to the sampling bag during the sampling, so that the sample cannot be adhered to samples of other parts in the body of the patient, the sampling is more accurate, the precision of a test result is higher, and the sampling difficulty of medical staff is reduced; according to the invention, the outer cylinder 1 is inserted into a patient body, and the inner cylinder 2 and the sampling device 3 slide relative to the outer cylinder 1 to enter a sampling position in the body and finish sampling, and because the front ends of the inner cylinder 2 and the outer cylinder 1 are provided with the soft sleeves, the pain caused by friction between the outer cylinder and the human body when the inner cylinder and the outer cylinder are inserted can be avoided; meanwhile, when sampling, the sampling sac is easy to contact with the wall surface of the vagina or cervix of a patient after being expanded, so that the sampling is easy and the pain to the patient is small in the sampling process; in addition, the positioning device is arranged on the sliding block, so that the sliding block of the inner barrel can be positioned at any position of the sliding groove relative to the outer barrel, the depth length of the inner barrel is controlled, different positions in the body of a patient are sampled according to the condition of the patient, and the device is simple in structure and higher in practicability.
