Blood measuring apparatus

A blood measuring apparatus comprising:

• first and second chambers which communicate with each other through an aperture;
• first and second electrodes which are provided with the first and second chambers, respectively;
• a liquid supply source which is configured to store a sheath liquid, and which is configured to apply a pressure to supply the sheath liquid to the first and second chambers, a pressure of the sheath liquid to be supplied to the first chamber different from a pressure of the sheath liquid to be supplied to the second chamber;
• a sheath flow generator which is configured to send a blood sample supplied to the first chamber, to the aperture while causing the blood sample to be converged by a sheath flow due to the sheath liquid supplied from the liquid supply source;
• and
• a swirling flow generator which is configured to cause the blood sample in the second chamber, to be converged by a swirling flow due to the sheath liquid supplied from the liquid supply source, thereby allowing the blood sample to flow in a direction separating from the aperture;
• wherein the liquid supply source includes:
• a single liquid supply source which is configured to supply the sheath liquid to the first and second chambers;
• a first supply path through which the sheath liquid is supplied to the first chamber;
• and
• a second supply path through which the sheath liquid is supplied to the second chamber,
• wherein the blood measuring apparatus further comprises a flow controller which is disposed in the second supply path, which is configured to adjust a flow rate in the second supply path, and which is configured by changing at least one of a length and a diameter of the second supply path.
