Abstract
A foldable brush self-sampling device for collecting of cell specimens from a body cavity, such as cervix, endometrium, rectum, nasal cavity and fauces, for diagnostic purposes, allows a user to collect cell specimens in the privacy of home. The device includes a sheath and a brush bar. The brush bar would fold into the sheath, which is with smaller diameter. The user inserts the sheath into the cavity easily and pushes the brush bar to expose the brush elements. After insertion of the sheath and push of the brush bar, the brush bar is rotated to obtain the specimen from the body cavity and then retracted in order to return the sheath.
Claims14
A foldable brush self-sampling device, comprising:
- a sheath;
- and
- a brush bar mounted in the sheath and comprising a elongated stem and a plurality of brush elements formed in a front end portion of the stem by a base, the base is greater than the sheath and would be folded into the sheath together with the brush elements, wherein in using, the base is exposed from the sheath by pushing the stem, and the base would extend to permit collecting interior specimen of humans.
The foldable brush self-sampling device of claim 6, wherein the cover is connected to the sheath by a hinge.
The foldable brush self-sampling device of claim 6, wherein the cover includes multiple caps, each connected to the sheath by a hinge.
A foldable brush sampling device, comprising:
- a tubular outer shell comprising an outer diameter almost the same as woman vagina, a proximal end and a distal end that has a circular position unit formed therein;
- a guide assembly selectively mounted in the outer shell and comprising a smooth head formed in a proximal end thereof and exposing from the outer shell;
- and
- a sampling assembly selectively mounted in the outer shell and comprising:
- a sheath;
- and
- a brush bar mounted in the sheath and comprising a elongated stem and a plurality of brush elements formed in a front end portion of the stem by a base, the base is greater than the sheath and would be folded into the sheath together with the brush elements, wherein in using, the base is exposed from the sheath by pushing the stem, and the base would extend-to permit collecting interior specimen of humans;
- whereby, the guide assembly mounted in the outer shell guides the personal cervical cell collector to insert into the vagina guided by the head, and the head touches the woman cervix and the position unit locks with a peripheral of the cervix for achieving position effect, continuously, the guide assembly is taken out and the sampling assembly is put into the outer shell to sample.
