Embodiment Construction

[0048] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0049] The oxygen supply parameter monitoring method disclosed in the present invention is specifically implemented as follows:

[0050] The oxygen supply parameter monitoring method disclosed in the present invention comprises the following steps:

[0051] Step 1, through the Hb-SO placed in the esophagus 2 The sensor detects the optical density OD and optical density change △OD of the blood in the adjacent descending aorta through the esophageal wall, and the Hb-SO 2 The sensor emits three beams of near-infrared light with different wavelengths;

[0052] Step 2. Use formula (1) and formula (2) to calculate the change amount ΔC of the reduced hemoglobin concentration in the blood respectively HHb , oxygen and hemoglobin concentration changes

Abstract

An oxygen supply parameter monitoring method and detection device for use in same. By arranging an Hb-SO2 sensor (1) in the esophagus, an optical density OD and an optical density change value △OD of the blood in the adjacent descending aorta (7) is detected through the wall of the esophagus (3), and corresponding calculation is performed to obtain a hemoglobin concentration of the blood. The present invention achieves routine monitoring of the hemoglobin concentration and even oxygen supply for a patient during a perioperative period to facilitate maintaining of the oxygen supply of the patient within a safe range, so as to prevent damage from oxygen deprivation, and greatly improve safety of anesthesia and surgical procedures. Furthermore, the present invention reduces the use of complicated invasive monitoring, and lighten the workload of anesthesiologists.

Description

technical field [0001] The invention relates to the medical field, in particular to a detection method and detection device for oxygen supply parameters. Background technique [0002] Perioperative blood loss and cardiopulmonary dysfunction will lead to a decrease in the body's oxygen supply. Real-time monitoring and maintenance of oxygen supply is the best strategy to prevent perioperative oxygen debt and hypoxic injury. Oxygen supply is based on the patient's actual cardiac output ( CO), arterial oxygen saturation (SaO 2 ) and hemoglobin content (Hb) three different measurement results estimated the body's oxygen supply in milliliters per minute. In addition to SaO 2 In addition to conventional pulse oximetry monitoring, CO is a special monitoring that requires the placement of a special pulmonary artery floating catheter or PiCCO catheter, which has high risks and costs and requires sufficient time. Hb can only be obtained by taking blood samples for analysis. At prese...
