Definitions

  • the invention relates to a speculum for allowing a user to inspect a body cavity, to a kit comprising said speculum and to a method of obtaining a cell sample from a body cavity comprising said speculum.
  • a speculum is a medical tool well known in the art that is used by health practitioners for inspecting a variety of body cavities.
  • the device contains adjustable blades that move from a first position, where the blades lie adjacent to one another in a closed formation, to a second position, where the blades are moved apart from one another into an open formation. Once the blades are moved apart, an inspection channel forms which allows the inside of the body cavity to be seen.
  • a speculum is commonly used to perform a cervical smear test on a female patient by using the speculum to open the vagina to gain access to the cervix and collect a sample of cells. The collected cells are then 'smeared' onto a slide or suspended in a vial of fluid and sent to the appropriate testing facility.
  • a cervical smear test is used in the diagnosis of cervical cancer, one of the most common types of cancer in women.
  • speculums are used by health practitioners to view body cavities of their patients.
  • Health practitioners usually have to use a light source located behind them which can be positioned so as to illuminate the body cavity. This can often be awkward if the cavity needs to be inspected closer or a sample needs to be collected because movement of the health practitioner can obscure the light and cast a shadow on the inspected cavity.
  • WO2006/136844 discloses a speculum with an attached mirror for use in performing cervical smear tests.
  • a single light source is incorporated into the cell collecting brush to act as a light guide.
  • An object of the invention is to provide an improved speculum to enhance the cell sampling procedure.
  • a speculum for allowing a user to inspect a body cavity which comprises more than one light source characterised in that each of said light sources emits a light beam which is angled towards a position of interest within the inspected body cavity.
  • a speculum for allowing a user to inspect a body cavity which comprises at least one light source configured to illuminate at least a portion of said body cavity.
  • kits comprising a speculum as defined herein and a cell sample collector.

Speculums may have adjustable blades that can be moved from a first, closed position to a second, open position allowing the formation of an inspection channel which allows the user to obtain a direct visual of the inside of a body cavity. Such references include speculum devices with two blades (“bivalve speculums”), four blades and multiple blades. The blades can be shaped in such a way so as to provide the most comfortable fit for insertion into a body cavity.
  • Speculums can be constructed from a variety of materials, such as hard, rigid plastics suitable for medical use. Such plastics include acrylonitrile butadiene styrene (ABS), styrene, polycarbonate, polypropylene, polyvinyl chloride (PVC), acrylic or ABS-polycarbonate mixes. Speculums can also be constructed from metal, such as stainless steel. In one embodiment, the internal surfaces of the speculum are white and/or have a polished surface finish. This embodiment provides the advantage of minimizing light loss and reflects the maximum amount of light into the body cavity.
  • Speculums may have various mechanisms that allow the opening of the blades, such as involving a ring having a cam surface that is movable along a path that lies around or outside the opening.
  • the blades may then be locked into an open position through use of a locking mechanism, such as a screw thread, or without the use of a locking mechanism, such as friction of an outer ring against an inner ring with a series of outwardly projecting protrusions along a cam surface.
  • the friction created by the inner ring protrusions against the outer ring may be such that it prevents the blades from closing against the natural closing effect of the body cavity, but can be easily overcome by the user applying manual force on the ring handles when they wish to close the speculum blades.
  • This arrangement has the advantage that it creates a degree of friction which maintains the blades in the open position without the need for a locking mechanism.
  • the protrusions on the inner ring can be positioned at various intervals so that the blades can be held open at a range of angles. This allows the user to choose the best angle to open the blades for maximizing the visibility of the inside of the body cavity.
  • the speculum body can include a grip to assist in insertion of the device into a body cavity and help with its correct placement.
  • the ring may include at least one handle extending away from the opening in the speculum body, enabling the user to rotate the ring.
  • the design of the handle on the ring could be such that it is suitable for right and left handed users.

  • the direction of the LEDs may be accurately maintained by virtue of the presence of a moulded plastic component which has a tubular channel for each LED and which points in the correct direction.
  • the light sources may be in a fixed parallel position relative to each other and the light beams emitted may be angled by the presence of additional component, such as a lens, light guide or equivalent component.
