oncometern.

1882 C. S. Roy in Jrnl. Physiol. 3 205 For convenience of description I have been recommended to give a name to this form of instrument, and will, therefore, refer to it under the name of Oncometer.

1896 T. C. Allbutt et al. Syst. Med. I. 826 It has been demonstrated by means of Roy's onkometer.

1899 Philos. Trans. (Royal Soc.) B. 191 239 The oncometer lever falls with the fall of blood-pressure, but continues to fall and remains down as the blood-pressure rises. This shows the cause of the rise of blood-pressure to be constriction of the peripheral blood vessels.

1935 C. J. Wiggers Physiol. in Health & Dis. xxxv. 528 The registration of volume changes in organs..is readily accomplished by placing an organ such as a kidney or spleen in a closed receptacle..called an oncometer or a plethysmograph.

1962 Proc. Royal Soc. 1961–2 B. 155 503 This type of container may be used as an oncometer to record changes in volume of the foetus.

1975 Amer. Jrnl. Physiol. 229 1596 The GP [sc. glomerular capillary pressure] was estimated from the sum of stop-flow pressure and the plasma colloid osmotic pressure (membrane oncometer).

1983 Amer. Jrnl. Clin. Pathol. 80 170 The colloid osmotic pressure..was measured on the serum of 250 individuals (healthy persons and patients) using a commercial oncometer.

2000 European Jrnl. Vascular & Endovascular Surg. 19 598 Interstitial fluid was collected by applying blister suction cups on the dorsolateral part of the foot and colloid osmotic pressure of this fluid..was measured in a colloid oncometer.
