Collection of biological fluids. At least one example is a polymeric sleeve including: an elongate body that defines a main passageway; an internal chamber defined within the main passageway; a first flange suspended within the internal chamber at a first position along the longitudinal central axis; and an aperture through the first flange, the aperture at least partially aligned with the longitudinal central axis.

A modular system which may aid in collection of bodily fluids, and more particularly collection of sperm. The system may include a plurality of components including a sleeve, a core and at least one cap. The system may be easily assembled and disassembled for interchangeability of each of its components as well as for cleaning and disinfection. The system may include a substantially rigid outer shell with a more malleable inner core. The core may be a single piece or multiple pieces and may be interchangeable depending on a user's preference and may reside within the outer shell but may be easily removable from the outer shell. A first end cap may include a face of substantially the same material as the inner core and may be interchangeable based on user preference as well.

A sampling device for collecting, storing and processing fluid samples for analysis is disclosed. The sampling device comprises a porous polymer monolith sampling substrate housed within a substantially impermeable housing. The housing surrounds the sampling substrate and further comprises a sampling aperture via which the sampling substrate is accessible externally from the sampling device.

To include a rotating holder 30 that is rotatably arranged in an opening of a casing 10 and detachably holds a part of a sperm sampler, a motor 50 that rotates and drives the rotating holder, a control unit 60, a battery 70, a single switch 20, 67, and an angular speed sensor 61 that detects an angular speed of the casing 10, where the control unit changes a rotation direction and a rotation speed of the motor according to a change in a turning angle of the casing 10.

Disclosed herein is method and system for determining quality of semen sample. Trajectories of objects, identified in each of plurality of image frames of semen sample, are generated by tracking movement of the objects across image frames, and compensating a drift velocity of the semen sample. Further, generated trajectories are classified into sperm and non-sperm trajectories. Finally, total concentration estimate and total motility estimate of the semen sample are computed to generate a semen quality index, which indicates quality of the semen sample. In an embodiment, the method of present disclosure uses a multi-level Convolutional Neural Network (CNN) analysis technique for effectively classifying the object trajectories into sperm and non-sperm objects. Also, since the present method includes estimating and compensating drift velocity in the semen sample, it enhances overall accuracy of motility estimation and semen quality analysis.

The straw comprises a tube (11) and a gas-permeable liquid-tight stopper (12), which stopper is disposed in the tube in the neighborhood of one end (16), which tube and which stopper are configured for the stopper to be able to slide in the tube towards the other end (17), said tube being transparent or translucent, said stopper comprising an identifier component (13) configured to emit, when it is illuminated with ultraviolet light, light of which the spectrum comprises at least one peak having a crest of predetermined wavelength in visible light, whereas when it is illuminated by visible light said identifier component does not emit said light of which the spectrum comprises said peak.

A cup used to receive, hold, measure and pour liquids, such a specimens, such as for a medical assay, is described. The cup comprises an open receiving upper chamber, two or more open sample-directing channels, and an open, calibrated and marked measuring column. When sitting on a level surface, fluid flows freely from the upper chamber through the sample-directing channels into the measuring column. A foot is under each fluid-directing channel. The base of the measuring column functions as an additional, such as a third, foot. Cups nest, with the two feet of the upper cup sitting into two sample-directing columns of lower cup. The measuring column and upper chamber taper to permit nesting. If the cup is tipped, it rests on two of three of: the two feet and the base of the measuring column, and a point on a lower perimeter of the upper chamber, such that fluid will not spill.

Bodily fluid collection systems are described where the system may be used for collecting and transferring sperm into a syringe. The syringe is configured to have a distal collection tip which is gently tapered or radiused to present a smooth and atraumatic surface and which is specifically configured and shaped to be inserted within and received by the collection receptacle. The distal collection tip has a shape which corresponds directly to a tapered reservoir defined at the bottom of the collection receptacle such that a distal opening defined through the tip is optimally positioned within the concentrated bodily fluid pooled within the reservoir for collection. Moreover, the gentle taper of the collection tip may present an atraumatic surface for inhibiting damage to the sperm contained within the ejaculate as the sperm is suctioned into the distal opening for insemination into the female.

A fluid analysis device can include a fluid inlet opening configured to receive a test fluid, and one or more fluid distribution channels in fluid communication with the fluid inlet opening and configured to receive and distribute the test fluid from the fluid inlet opening using a passive self-loading mechanism. The device can include a plurality of assays fluidly isolated from each other and configured to receive the test fluid from the one or more fluid distribution channels.

A device for testing the quality of a biological sample, preferably semen, in cooperation with an electronic apparatus, the device comprising; a slide slot adapted for receiving a slide containing a biological sample; a receiving surface adapted for receiving an electronic apparatus containing a camera, where the receiving surface comprises a through hole extending through said receiving surface; a light source arranged opposite the through hole; a lens arranged between the slide slot and the receiving surface, and adapted to magnify the image received at the receiving surface; where the slide slot is arranged between the light source and the through hole, the device further comprising a housing attached opposite the receiving surface, the housing having a shape allowing for a plurality of stable resting conditions in which the electronic apparatus lies on the receiving surface, and alignment between the camera and the through hole is maintained by friction.
