Abstract

This utility model discloses a stool specimen collection auxiliary device, belonging to the field of excrement collection technology. It includes a specimen collection assembly comprising an L-shaped push-pull support rod positioned above the toilet, two inverted U-shaped retaining plates symmetrically and movably connected to the support rod portion of the L-shaped push-pull support rod, a detachable auxiliary collection tube for receiving the stool specimen disposed between the two U-shaped retaining plates, and a collection box threadedly connected to the bottom end of the auxiliary collection tube. The two U-shaped retaining plates are symmetrically engaged at the top ends of the toilet. When the L-shaped push-pull support rod is pushed and pulled, the two U-shaped retaining plates slide along the top edge of the toilet, adjusting the position of the auxiliary collection tube and collection box within the toilet cavity, aligning them with the patient's anus. This utility model ensures that the auxiliary collection tube and collection box are accurately aligned with the patient's anus, improving the accuracy of the collection process.
