    Abstract: 1277762 Blood sampling apparatus MICROMEDIC SYSTEMS Inc 16 July 1969 [26 July 1968] 35716/69 Heading A5R Apparatus is provided for obtaining a blood sample from a patient's finger using a collector device 15, Fig. 11, of the type disclosed in Specification 1277761 having a tube 32 and a resilient funnel member 35 with incisor lancets 38a, 38b, the apparatus having a mounting 12, Fig. 2, having a through passage 12c in which the collector 15 is supported, a striker mechanism having a releasable member 17 adapted to strike a lower end of tube 32 to force lancets 38a, b into a patients' finger placed over funnel 35, a finger holder 8, and means for periodically varying the intensity of clamping of said holder. Holder 8 is pivoted at 7 and has a pin 8c which during pivoting of the holder engages member 17, to pivot the latter against springs 14, and then releases member 17 which consequently strikes tube 32. Holder 8 is retained in its clamping position by engagement of teeth 8f with a grooved rod 29 on a lever 25, the degree of clamping being varied by a massaging-type movement of a finger support 6 on a lever 19 driven through an eccentric by a motor. The first drops of impure blood are absorbed by a pad 40 in funnel 35, the remaining sample passing into tube 32 until a light beam, passing through tube 32 from a source to a photo cell in mounting 12, is interrupted, whereupon a solenoid coil 23 is energised and attracts an armature 22 on a lever 21, the end of which lever thus becomes engageable with a projection 19a on lever 19 to move levers 21 and 25 thus releasing holder 8 which is acted on by a return spring 11, the actuation of the solenoid also stopping the motor. Holder 8 may alternatively be released and the motor stopped via a push button 4. In an alternative embodiment, Figs. 13-16 (not shown) the finger is clamped and massaged between a fixed swell (45) on a casing (42) and a sponge pad (46) secured to a stirrup (41) pivoted on an eccentrically driven pin (43).

    Abstract: 1281353 Reciprocating pumps MICROMEDIC SYSTEMS Inc 15 Aug 1969 [16 Aug 1968] 40900/69 Heading F1A A pump, e. g. for metering liquids in laboratories, comprises a piston 3 reciprocable in a cylinder 1 in synchronism with a rotary face valve 6 driven by a wheel 72, the cylinder 1, valve 6 and a coupling member 30 being mounted in a casing 37, 38 which is removably mounted by bayonet pins 50, 51 in bayonet slots 53, 54 in a ring 55 pivoted in a frame 59, a releasable locking pin, Fig. 4 (not shown), preventing rotation of the casing in the ring. A spring 34 biases valve member 6 against valve seat 5 to provide sealing when the casing is detached from the frame, additional spring-loading during operation being provided by spring 63 acting through ball 60 and coupling member 30. Valve 6 may be of P. T. F. E. and has grooves 25, 26 for alternately connecting cylinder port 12 to inlet and outlet ports 20 in seat 5, Figs. 2 and 3 (not shown). The grooves 25, 26 may be arranged in the form of a cross, or may be arcuate. Coupling member 30 has sawtooth projections, Figs. 4 and 5 (not shown), for engaging drive pins 70, 71 of wheel 72. The locking pin passes through one of the trunnions supporting ring 55 and is spring-loaded into an axial slot in casing 38, a bevel 69 depressing the pin for entry of the casing into the ring.
