Detailed Description

The following detailed description will be made in conjunction with embodiments and the accompanying drawings.

Examples

As shown in fig. 1-2, the utility model discloses a wholly constitute by gathering pipe 1, collection head 2, piston 3, spring 4, piston rod 5 and have end cap 8 of end cap hole 7. The inner wall of the collecting pipe 1 is provided with a limiting block 10, the limiting block 10 is preferably made into a ring shape, the limiting block can be formed by protruding the inner wall of the collecting pipe 1 to one side of the central axis line of the collecting pipe 1, or a single ring-shaped block can be fixed in the collecting pipe 1.

The collection head 2 is connected with one end of the collection tube 1, and the plug 8 is connected with the other end of the collection tube 1. In the collection tube 1, because the limiting block 10 is arranged, the inside of the whole collection tube 1 is divided into two cavity parts by the limiting block 10, one is a collection cavity 11 between the limiting block 10 and the collection head 2, and the other is a compression cavity between the limiting block 10 and the plug 8.

The piston 3 is arranged in the collection chamber 11, i.e. the piston 3 is located to the left of the stopper 10 and near one end of the collection head 2, as seen in the position shown in fig. 2. The spring 4 and the piston rod 5 are arranged in the compression chamber, i.e. the spring 5 and the piston rod 5 are both located on the right side of the stopper 10 as seen from the position shown in fig. 2. When the piston rod is connected, one end of the piston rod 5 penetrates through the plug hole 7 and then is fixedly connected with the piston 3, the spring 4 is sleeved on the piston rod 5, one end of the spring 4 is in contact with the limiting block 10, and the other end of the spring is fixed on the piston rod 5. After the plug 8 and the collection tube 1 are fixed, the spring 4 is always in a compressed state, so that the piston rod 5 is continuously supported towards the side of the plug 8.

For convenient operation, a bulge 9 is arranged on the outer side pipe wall of the collecting pipe 1, a push head 6 is arranged at the end of the piston rod 5, and the shape of the push head 6 can be any shape.

The collection head 2 is a component for collecting secretions, which can be implemented in two different configurations. In the first structure, the collecting head 2 is a semi-closed hollow cylinder, that is, the collecting head 2 has a closed end and a non-closed end, the end face of the closed end is provided with a plurality of collecting holes 12, and the non-closed end is fixedly connected with the collecting tube 1. The collecting head 2 and the collecting tube 1 are connected together in a threaded, buckling or inserting manner to ensure that the collecting head 2 can be detached from the collecting tube 1 and ensure that the piston 3 can be assembled inside the collecting tube 1.

A second configuration of the pick head 2 is that the pick head 2 is comprised of an inner liner 21, and an outer liner 22 disposed outside the inner liner 21. I.e. the inner liner 21 is completely inside the outer liner 22, the inner liner 21 needs to be in close contact with the outer liner 22 and the outer liner 22 can rotate along the central axis of the inner liner 21. Meanwhile, the inner liner 21 and the outer liner 22 are respectively provided with the collecting holes 12 with the number and the positions corresponding to each other one by one. While the inner liner 21 is connected to the collection tube 1 by threading, plugging or plugging.

When in use, the collecting holes 12 on the outer lining 22 are communicated with the collecting holes 12 on the inner lining 21 only by forcibly rotating the outer lining 22; when the collecting device is not used, the outer bushing 22 only needs to be rotated forcibly, so that the collecting holes 12 on the outer bushing 22 and the collecting holes 12 on the inner bushing 21 are staggered.

The utility model discloses an use flow does: after the whole collector is held in the palm of the hand, the pushing head 6 is extruded by the holding power, the pushing head 6 can transmit the power to the piston 3 through the piston rod 5, and the piston 3 can move in the collecting cavity 11, so that the air in the collecting cavity 11 is discharged through the collecting hole 12; at this time, the spring 4 is further in a compressed state.

The collection head 2 of the collection tube 1 is then inserted into the female genital tract, and the pushing head 6 is then released. After the collection chamber 11 is loosened, the piston rod 5 will bring the piston 3 back to the initial state under the action of the elastic force of the spring 4, so that negative pressure (i.e. suction) is formed inside the collection chamber 11, and then secretion inside the female genital tract is sucked into the collection chamber 11 through the collection hole 12, thereby completing the sample collection item.

The above description is only for the preferred embodiment of the present invention and should not be construed as limiting the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
