Abstract: 1346532 Electro-chemical analysis BECKMAN INSTRUMENTS Inc 13 March 1972 [18 March 1971] 11706/72 Heading G1N The invention relates to apparatus for the automatic analysis of a blood sample for simultaneous pH, pCO 2 , and PO 2  estimation, and including subsequent washing and calibration cycles. The sample is automatically injected from the disposable syringe in which it taken from the patient. The three indicator electrodes work with a common reference electrode. GENERAL ARRANGEMENT & ELECTRODE MOUNTING As shown Figs. 1, 8, 9 the cell is mounted on a rotatable plate 34 and comprises a transparent plastics block housing three electrodes 14, 16, 18, two controlled heaters 21, 24, and a container for calibrating solution (maintained at the same temperature). The electrodes are mounted in sleeves 192 with the same external dimensions and dip into recesses connected by a bore 276 terminating in a capillary liquid junction 234 connected to a reservoir 236 housing a reference electrode 238. A porous plug 261 backs-up the capillary and is bypassed by a pump 268 for flushing the capillary system.  ELECTRODE DETAILS  The pH electrode may be a standard glass electrode; pCO 2 , a glass electrode covered by an e.g. P.T.F.E. membrane spaced therefrom by a liquid permeable nylon mesh; pO 2 , a metal cathode covered by a membrane; reference electrode, calomel or Ag/Ag C1; electrolyte, K Cl including a bicarbonate (for pCO 2 ). OPERATION After the sample syringe has been attached to a suitable connection on plate 34, the cycle is started by a manually operated switch P1, and thereafter controlled by a 60-step time Fig.13 (not shown) illustrates the control circuit. The disc is rotated by a reversible motor 62 and runs till pin 76 on the disc engages tabs 78, 80 to open a micro switch and stop the motor with the syringe opposite the cell access bore. The syringe drive forces the plunger home to inject the sample in the cell. This drive comprises a block 90 slidable in a slot 92 and driven by a rack 100 and a reversible motor (108) Fig.3 (not shown). A latching mechanism 140 having fingers 148, 150 which grip the syringe head as rollers 152, 154 leave the guides 158, 160 causes the plunger to be withdrawn as the drive retracts. This sucks wash solution through the cell access bore. Fig. 9 which illustrates the "plumbing" for wash and calibration cycles together with Figs. 10, 11, 12 (not shown) illustrating the corresponding valve structure (which is operated from the syringe drive) are substantially self-explanatory. The calibration solution is recirculated and stored under a constant pressure of CO 2  and O 2 .
