Fecal specimen collector
View Patent ↗The present invention provides a fecal specimen collector. The fecal specimen collector consisting of a top cover, a bottle body, a specimen output end and a bottom cover, wherein a lower portion of the top cover forms a sampling end which may be inserted into the bottle body through an upper end of the bottle body, the top cover is connected with the upper end of the bottle body, the specimen output end is hermetically coupled with a lower portion of the bottle body, and the bottom cover surrounds the specimen output end and couples to the bottle body, wherein a convex is formed on the inner center of the bottom cover, and is inserted into a specimen output port of the specimen output end. The fecal specimen collector according to the present application has a small and delicate structure which has the advantages of easy operation, convenient portability and pollution free, etc.
1. A fecal specimen collector comprising:
a top cover comprising a sampling stick, the sampling stick comprising a plate and an elongated sampling end extending downwardly from the plate;
a bottle body into which the sampling stick is inserted;
a sealing ring and a spacing septum disposed within the bottle body, the sealing ring and the spacing septum dividing the bottle body into a first chamber and a second chamber, the second chamber containing diluent liquid;
a specimen output end having a fluid passageway in fluid communication with the second chamber of the bottle body, the specimen output end further having an orifice at the bottom wall of the specimen output end through which the diluent liquid is discharged;
a bottom cover comprising a convex being configured to engage the orifice of the specimen output end for preventing the diluent liquid from discharging upon being pressed; and
a through hole formed in the spacing septum and the sealing ring, through which the elongated sampling end of the top cover is inserted to sealingly engage the plate with the sealing ring;
wherein the orifice is configured to have a sufficiently small dimension, wherein when the convex is disengaged from the orifice and the orifice is positioned downwardly, the diluents liquid is not discharged unless the bottle body is pressed.
2. The fecal specimen collector of claim 1 , wherein the elongated sampling end comprises a brush structure.
3. The fecal specimen collector of claim 1 , wherein the elongated sampling end comprises a stick and includes a plurality of sheets protruding from the stick.
4. The fecal specimen collector of claim 1 , wherein the top cover comprises a handle from which the sampling stick extends, and the sampling stick further comprises a connection rod for connecting the handle to the plate.
5. The fecal specimen collector of claim 1 , wherein the bottle body comprises a hollow tube having a top end and a bottom end, the top end being provided with an internal screw structure, and the top cover comprises an external screw structure for operatively engaging the internal screw structure.
6. The fecal specimen collector of claim 1 , wherein the bottle body comprises a hollow tube having a top end and a bottom end, the top end being provided with an external screw structure, and the top cover comprises an internal screw structure for operatively engaging the external screw structure.
7. The fecal specimen collector of claim 1 , wherein the specimen output end is coupled to the bottle body by interference fit.
8. The fecal specimen collector of claim 1 , wherein the specimen output end comprises a sealing groove and a secondary sealing ring disposed within the sealing groove.
9. The fecal specimen collector of claim 1 , wherein the convex has a taper shape.
10. The fecal specimen collector of claim 1 , wherein the lower surface of the round plate which contacts the sealing ring is flat, and the upper surface of the sealing ring which contacts the lower surface of the round plate is flat.
11. The fecal specimen collector of claim 2 , wherein the brush structure has a diameter greater than the diameter of the through hole of the spacing septum.
12. The fecal specimen collector of claim 3 , wherein the plurality of sheets have a diameter greater than the diameter of the through hole of the spacing septum.
13. The fecal specimen collector of claim 1 , wherein the sealing ring has a diameter smaller than the diameter of the spacing septum.
