Definitions
- the sample strip is arranged to produce a detectable change, depending upon characteristics of the urine sample, and the reader is arranged to measure this change and display the result to a user via a display screen.
- the latch may comprise mutually cooperating formations formed on the cover and remainder of the cartridge respectively.
- the cartridge may comprise a test strip, or other sensor element, for receiving a sample.
- the cover may cover at least part of the test strip.
- the apparatus may comprise a plurality of cartridges. Each cartridge may be supplied in a sealed package.
- Figure 1 is a perspective view from above of a reader and cartridge of test apparatus
- Figure 4 is a perspective view from below of the apparatus of figure 1 ;
- Figure 5 is a simplified cross-sectional view of part of the cartridge of the test apparatus of figure 1 ;
- Figures 6 to 8 are simplified cross- sectional views of part of the cartridge of the test apparatus of figure 1, and part of the reader of figure 1, showing the cartridge separate from, partially introduced into and fully engaged with the cartridge; and Figure 9 is a perspective view of part of an inside surface of the cartridge.
- test apparatus for analysing urine, or other liquid, samples.
- the tester is particularly intended for analysing a urine sample for the purposes of pregnancy or ovulation testing, but it could be used for making other tests.
- the apparatus comprises an electronic reader 1 and a cartridge 2 having a cap 3.
- the cartridge comprises a moulded plastics body comprising a moulded plastics support 4 supporting a test strip 5.
- the test strip 5 is for receiving a urine sample and providing a detectable change to indicate a property of the sample, such as, in the case of a pregnancy test strip, the concentration of human Chorionic Gonadotrophin in urine. Test strips, sticks and other test or assay apparatus are well known in the art and so need not be described in further detail. Any suitable sensor element could be used in place of the test strip 5 shown.
- the test strip 5 is supported in the cartridge so that it extends from opposite ends of the cartridge.
- the cartridge 2 is provided with a moulded plastics cap 2.
- the cap 2 fits snugly over one end of the cartridge with a close sliding fit. When fitted, the cap encloses the test strip 5 extending from that end of the cartridge ' .
- the electronic reader 1 comprises a moulded plastics body.
- the body is configured to engage with the opposite end of the cartridge 2 to the cap 3 with a snap fit.
- the body comprises an interface portion 6 which, when the cartridge and body are engaged with each other, extends into the cartridge and receives the test strip 5.
- Resiliency flexible formations 7 are provided on an inside surface of the body of the cartridge 2 which capture a part of the interface portion 6 of the body of the electronic reader, causing the reader and the cartridge to releasably engage with each other with a snap fit.
- the body of the electronic tester houses electronic components and circuitry arranged to read a test strip 5 of a cartridge 2 engaged with the tester, and to display a result to a user via an LCD screen 8. Electronic readers are known, and so will not be described in further detail here.
- the cartridge 2 and cap 3 are respectively provided with mutually cooperating components of a latch, operative to prevent removal of the cap 3 from the cartridge 4 unless the cartridge 2 is engaged with the electronic reader 1.
- the latch comprises a wedge-shaped protrusion 9 formed on the inside surface of an elongate projection 10 to the wall of the cap 3. The thin end of the wedge faces out from the opening into the cap. Owing to the material from which the cap is moulded the projection is resiliently flexible relative to the remainder of the cap.
- the latch further comprises an aperture 11 in an indented region of the outside of the cartridge 2 over which the cap fits, spaced from the edge of the cartridge.
- the wedge shaped protrusion contacts the outside of the cartridge causing the elongate projection to the wall of the cap to flex outwards allowing the protrusion to ride over the cartridge until it snaps into the aperture 1 1 allowing the protrusion 10 in the wall of the cap to return to its original state. If the cap is urged away from the cartridge the thick end of the wedge shaped protrusion will bear against the edge of the aperture 1 1, preventing removal of the cap from the cartridge.
- the latch may be implemented in a variety of different ways whilst still providing the same functionality,
- a protrusion on the cartridge could be received into an aperture or recess in the cap.
- Cartridges are supplied with a cap fitted. They must therefore be engaged with a reader before the cap can be removed to enable a urine sample to be applied to the test strip. It is therefore impossible for a sample to be introduced to the test strip without the cartridge being engaged with a reader. This eliminates, or at least substantially reduces, the risk of a test strip being incorrectly read as a result of the test strip being contaminated before use, or coming into contact with a sample before being monitored by the reader.
