Drop detection of human follicle fluid in a test tube
View Patent ↗The present disclosure discloses an apparatus and a method for detecting first and subsequent drops of follicle fluid falling into a test tube during an aspiration process. A pair of optical devices (emitter and detector) is positioned at opposite side of the test tube. The emitter emits a beam of light towards the detector. As soon as a drop of the follicle fluid falls into the test tube, a signal processing circuitry detects a change in intensity of the light received by the detector. Further, the intensity of beam is compared with a pre-defined intensity. Based on the comparison, if the difference between the pre-defined intensity and intensity is greater than a pre-defined threshold value, the signal processing circuitry generates an electrical signal indicating the detection of the first drop of the follicle fluid falling into the test tube.
1. An apparatus for detecting a drop of follicle fluid falling into a test tube, the apparatus comprising:
a test tube for storing follicle fluid, wherein the test tube has a cork fitted at open-end of the test tube, and wherein the cork has a passage allowing an inlet tube, carrying the follicle fluid, to pass through the test tube;
a pair of optical devices positioned at an opposite side of the test tube,
wherein the opposite side indicates a position on the test tube where an incoming follicle fluid flow breaks into a drop and detaches from the inlet tube, and wherein the pair of the optical devices comprises a first optical device and a second optical device, and wherein the first optical device emits a beam of light of a pre-defined intensity, through the test tube, towards the second optical device;
a signal processing circuitry, coupled with the test tube, to detect first and subsequent drops of the follicle fluid by monitoring an intensity of the beam of light received by the second optical device, comparing the intensity of the beam of light with the pre-defined intensity, and detecting the first and subsequent drops of the follicle fluid in the test tube based upon a difference between the pre-defined intensity and the intensity being determined as greater than a pre-defined intensity threshold value; and
wherein the apparatus further comprises an alert mechanism for generating an audio alert and a visual alert for indicating to an operator that the first and subsequent drops of the follicle fluid are falling into the test tube.
2. The apparatus of claim 1 , wherein the first optical device is an emitter and the second optical device is a detector.
3. The apparatus of claim 1 , wherein the difference is based on opacity or transparency properties of the follicle fluid.
4. A method for detecting a drop of follicle fluid falling into a test tube, the method comprising:
positioning a pair of optical devices at an opposite side of the test tube,
wherein the test tube has a cork fitted at open-end of the test tube, and
wherein the cork has a passage allowing an inlet tube, carrying the follicle fluid, to pass through the test tube, and wherein the opposite side indicates a position on the test tube where an incoming follicle fluid flow breaks into a drop and detaches from the inlet tube, and wherein the pair of the optical devices comprises a first optical device and a second optical device, and
wherein the first optical device emits a beam of light of a pre-defined intensity, through the test tube, towards the second optical device; and
detecting, by a signal processing circuitry coupled with the test tube, first and subsequent drops of the follicle fluid by monitoring an intensity of the beam of light received by the second optical device, comparing the intensity of the beam of light with the pre-defined intensity, and detecting the first and subsequent drops of the follicle fluid in the test tube based upon a difference between the pre-defined intensity and the intensity being determined as greater than a pre-defined intensity threshold value; and
wherein the method further comprises generating an audio alert and a video alert, by an alert mechanism, for indicating to an operator that the first and subsequent drops of the follicle fluid are falling into the test tube.
5. The method of claim 4 , wherein the first optical device is an emitter and the second optical device is a detector.
6. The method of claim 4 , wherein the difference is based on opacity or transparency properties of the follicle fluid.
