1. In this utility model, when in use, the user separates the push pen from the cannula through the second connection mechanism, holds one of the handles to insert the cannula into the puerpera’s vagina, and holds the other handle to insert the push pen into the insertion tube. The tube pushes several expansion rods away from the center of the intubation tube. One end of the expansion rod drives the push shell to expand outward, and the push shell drives the medical elastic bandage on its surface to stretch. The surface of the medical elastic bandage is also equipped with medical absorbent cotton. , used to absorb vaginal secretions after the absorbent cotton touches the inner wall of the vagina. After a while, the user pulls out the push pen. Under the action of the rebound mechanism, several expansion rods rebound to their original positions, and finally The user pulls out the intubation tube, and removes the medical elastic bandage through the first connection mechanism for testing. This setting realizes a large-scale sampling of the inside of the puerpera's vagina and ensures the accuracy of the sampling results.

Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model.

As shown in Figures 1, 2, 3, and 4, a vaginal secretion sampler includes two handles 1, a first connection mechanism 2, a rebound mechanism 3, and a second connection mechanism 4, and the two handles 1 are far away from each other. One end is fixedly installed with pushing pen 5 and connecting ring 6 respectively, and one side of connecting ring 6 is fixedly installed with intubation tube 7, and the surface of intubation tube 7 is sleeved with several medical elastic bandages 8 along its length, and several medical elastic bandages The inner surface of 8 is sleeved with several push shells 9, and the outer surface of several medical elastic bandages 8 is fixedly equipped with medical absorbent cotton 10, and the first connecting mechanism 2 is used to connect the two ends of several medical elastic bandages 8, The other end of the intubation tube 7 is fixedly equipped with a closing plate 11, and the surfaces of several push shells 9 are fixedly equipped with several expansion rods 12, and the plurality of expansion rods 12 are all slidably inserted into the inner wall of the intubation tube 7, and the rebound mechanism 3 It is used to limit the distance between one end of several expansion rods 12 in the horizontal direction and the horizontal center of the cannula 7 , and the second connecting mechanism 4 is used to connect two handles 1 .
