Abstract: An incident light beam from a light source (7) is guided by a light guide (11) onto the skin surface (5). Infra-red radiation is removed from the reflected beam by a filten20 located between the skin surface and two phototransistors (14, 15). The phototransistors (14, 15) detect the reflected light and has red and blue filters respectively. The outputs of the phototransistors are compared in a differential amplifier (27) and the differential amplifier output signal (29) is adjusted to zero by an offset bias circuit (28) for no colour change. When the surface changes colour the red and blue optical filters pass different amount of light and a difference is produced between the phototransistor outputs. This difference is amplified by the differential amplifier to provide an output signal representative of the colour change of the surface.

Abstract: A lancet device has a two part housing (1) integrally moulded in a folded out configuration with a spring (2), a lancet body (3) encasing a needle (4), and a needle cap (5) concealing the needle tip. The spring (2) is a zig-zag connected at one end to one housing part (7) by a web (19) and merging at the other end into the lancet body (3). This is folded over with the spring (2) about the web (19) into the housing part (7), and the other housing part (6) is closed over about web hinges (8) and fastened. A trigger (9) is incorporated in the other housing part (6) and is deformable inwardly to release the lancet body (3) from a catch arrangement (14, 21) which holds the lancet retracted with the spring energised. The needle cap (5) can be used for the retraction before being removed.

Abstract: A blood sampling device has a tubular body (1, 2) housing a spring loaded (7) lancet (8) whose needle (17) is initially protected by a cap (20) which projects out from the forward end of the body. A rocker-like trigger (9) is formed as part of the moulded body (1, 2) and holds the lancet (8) in a retracted position when the lancet is pushed back by the projecting cap (20). The cap can then be removed by a twist and pull action, breaking it free from the lancet body, which is prevented from rotating. Pressure on the trigger (9) releases the lancet (8), which is shot forward by the spring (7) for momentary projection of the needle tip (19), and then retracts to bring the needle tip within the body.

Abstract: A disposable reagent unit including a base strip (12) with a plurality of spaced holes (24, 18, 20, 22), a double face tape (32), a reagent and a lot identification paper in side-by-side adjacent relationship, a wick (38), and a cover strip with a hole for engagement with a diagnostic instrument quantitative of an analyte in a liquid such as glucose in blood. Blood is deposited in the blood bowl (28) and is wicked to the reagent (36) for subsequent color change or other detectable change to be measured by a diagnostic instrument. The color intensify of the reagent is proportional to the analyte such as glucose in the blood. A blood or fluid guard of a predetermined geometrical shape can be secured to the reagent unit to protect the diagnostic instrument from transmission of fluid, such as blood. Any particular portion of the surface of the diagnostic reagent unit can be covered by the blood or fluid guard so as to protect, shield and cover the predetermined surfaces of the diagnostic instrument.

Abstract: A blood taking device has a cylindrical needle holder (1) carrying or adapted to carry a double needle (6, 7) and being slidably mounted in a safety shield (4). A resilient finger grip (13) is fixed to the unbroken wall of the holder (1) and extends out of a longitudinal slot (15) of the shield (4). Outside the shield the finger grip has parts (74, 75) which are resiliently urged from outside towards the shield (4) and are constructed with a locking nose (76) engageable from outside in a first widened slot (19) and a second widened slot (20) of the shield to define an advanced blood taking position and a retracted holding position of the finger grip (13), respectively. The longitudinal slot (15) extends rearwardly beyond the second widened slot to permit further retraction of the finger grip (13) to a definitive locking position. Preferably, the shield (4) has a third widened slot (77), through which a rearwardly directed tongue (75) of the finger grip (13) can be pressed inwards to a shielding position behind the rear needle (7) to establish the definitive locking position. In a device having a fixedly mounted double needle (6, 7) the front needle (6) can advantageously be encapsulated in a needle sheath (40) which is removably connected with the front end of the holder (1) in contamination-proof manner.

Abstract: A blood collector system (20) utilizes a standard disposable needle assembly (22) and standard blood collecting and receiving tubes (38) of the type sealed by a pierceable septum (40). The system (20) has a hollow cylinder (42), including an internally apertured sleeve (46) into which the needle assembly (22) is mounted and into which the sealed blood collecting tubes (38) are inserted to be pierced by a needle (34) of the needle assembly (22). A member (48), such as a plate, is pivotably mounted to the cylinder (42). A hole (56) in the plate accommodates the needle assembly (22) while the needle assembly (22) is retained in the cylinder (42). When the blood specimen collection is complete, the plate (48) is moved in a pivoting motion whereby it catches the needle assembly (22) and ejects it from the cylinder (42). The apparatus of the invention eliminates the need for a protective sheath to be replaced on the needle assembly (22) before the needle assembly (22) is discarded, and thereby minimizes the health care worker's exposure to accidental needle pricks.
