Detailed Description

As shown in fig. 1-3, a fecal sampling device according to an embodiment of the present invention includes a sampling swab, a swab outer tube 4 and a cap 7.

Sampling swab includes sampling head 1, sampling rod 2 and push rod 3, and sampling head 2 is connected to the one end of sampling rod 1, and push rod 3 is connected to the other end, and push rod 3 sets up with sampling rod 2 is perpendicular, like the structure of L type. The swab outer tube 4 is open at both ends, a sealing baffle 5 is arranged inside (for example, in the middle section) the swab outer tube 4, and the sampling swab penetrates through the sealing baffle 5 and is arranged in the swab outer tube 4. Because the center of the sealing separation blade 5 is provided with a through hole for the sampling rod 2 to pass through, and the sealing separation blade 5 has elasticity, the sampling rod 2 can rotate in the through hole of the sealing separation blade 5 and move up and down along the radial direction, the outer edge of the sealing separation blade 5 is propped against the inner wall of the swab outer tube 4, the sealing separation blade 5 is relatively fixed in the swab outer tube 4 due to the friction effect of the sealing separation blade 5 and the inner wall of the swab outer tube 4, and a limit stop can be arranged for fixing if necessary. The length of the sampling swab is greater than that of the swab outer tube 4, at least one groove 6 is formed in the tube wall of one end, close to the push rod 3, of the swab outer tube 4 in the radial direction of the swab outer tube 4, and the push rod 3 can be pushed into the groove 6. The length of the push rod 3 is larger than the radius of the swab outer tube 4, and when the push rod 3 enters the groove 6, the push rod 3 can extend out of the swab outer tube 4, so that the push rod 3 can be conveniently pulled out of the swab outer tube 4. Alternatively, two grooves 6 may be provided, for example, as shown in fig. 5, the lengths of the two grooves 6 are different, the length interval of the grooves 6 is 0.5-1cm, and the lengths of the two grooves 6 may be 1.5cm and 2.5cm, for example. The groove 6 is used for quantitatively controlling the length of the sampling head 1 extending into the intestinal tract, usually, an infant chooses not to push the push rod into the groove, a child chooses to push the push rod 3 into the groove 6 with smaller length, and an adult chooses to push the push rod 3 into the groove 6 with larger length. Due to the limiting function of the groove 6, a user does not need to worry about the fact that the sampling head does not extend into the sampling head to a sufficient or excessive length.
