## Abstract

The present disclosure discloses an apparatus and a method for detecting level of the follicle fluid falling into a test tube during an aspiration process. The apparatus may be configured for detecting the level of the follicle fluid falling into the test tube. Upon detecting that the level reaches the pre-defined threshold level in the test tube, the apparatus may be further configured to notify a doctor about the level of the follicle fluid into the test tube via an audio alarm or visually through the ultrasound monitor. The notification enables the doctor to concentrate on the aspiration process and further facilitates to prevent spilling of the follicle fluid from the test tube, once the follicle fluid reaches the pre-defined threshold level of the test tube.

## Claims

### Claim 1

A method for detecting level of follicle fluid in a test tube , the method comprising:
positioning a first optical device and a second optical device, on a test tube, in a manner such that the second optical device is aligned opposite to the first optical device, wherein the first optical device emits beam of a pre-defined intensity, through the test tube, towards the second optical device;
extracting follicle fluid in the test tube by generating vacuum pressure using an aspirator;
monitoring, via a signal processing circuitry, intensity of the beam received by the second optical device;
comparing, via a signal processing circuitry, the intensity of the beam with the pre-defined intensity; and
detecting, via a signal processing circuitry, the level of the follicle fluid in the test tube when difference between the pre-defined intensity and the intensity is greater than a pre-defined threshold value, wherein the level indicates that the follicle fluid extracted in the test tube is reached to a pre-defined level.

### Claim 2 (depends on 1)

The method of claim 1 further generates an alert for indicating an operator that the follicle fluid extracted in the test tube is reached to the pre-defined level.

### Claim 3 (depends on 1)

The method of claim 1, wherein the alert is generated as an audio alert or a visual alert.

### Claim 4 (depends on 1)

The method of claim 1, wherein the difference is based on the opacity or transparency properties of the follicle fluid.

### Claim 5

An apparatus for detecting level of follicle fluid in a test tube, the apparatus comprising:
a test tube for storing follicle fluid;
a casing coupled with the test tube, wherein the casing comprises a first optical device and a second optical device, and wherein the first optical device and the second optical device are positioned, on the test tube, in a manner such that the second optical device is aligned opposite to the first optical device, and wherein the first optical device emits beam of a pre-defined intensity, through the test tube, towards the second optical device; and
a signal processing circuitry, coupled with the casing, facilitates to detect the level of the follicle fluid by
monitoring intensity of the beam received by the second optical device,
comparing the intensity of the beam with the pre-defined intensity, and
detecting the level of the follicle fluid in the test tube when difference between the pre-defined intensity and the intensity is greater than a pre-defined threshold value, wherein the level indicates that the follicle fluid extracted in the test tube is reached to a pre-defined level.

### Claim 6 (depends on 5)

The apparatus of claim 5 further an alert mechanism for generating an alert for indicating an operator that the follicle fluid extracted in the test tube is reached to the pre-defined level.

### Claim 7 (depends on 5)

The apparatus of claim 5, wherein the alert is generated as an audio alert or a visual alert.

### Claim 8 (depends on 5)

The apparatus of claim 5, wherein the difference is based on opacity or transparency properties of the follicle fluid.
