Catheter occlusion detection sensor

An intravenous (IV) catheter occlusion detector, the detector comprising:

• a panel comprising a distal surface configured to be pressed against a skin of a patient, a proximal surface opposite the distal surface, a first portion configured to be positioned proximate to an IV catheter when the distal surface is pressed against the skin of the patient, and a second portion opposite the first portion;
• an optical absorption sensor positioned at the second portion of the panel, the optical absorption sensor comprising:
• a light source configured to transmit red light and infrared light through the skin of the patient towards a vein of the patient;
• and
• one or more photodetectors configured to receive and measure the red light and the infrared light reflected off the vein of the patient, thereby determining an absorption ratio of a fluid in the vein of the patient;
• and
• a display screen on the proximal surface, the display screen being configured to display the absorption ratio.

An intravenous (IV) catheter occlusion detector, the detector comprising:

• an optical absorption sensor comprising:
• a light source configured to transmit red light and infrared light through skin of a patient towards a target site;
• and
• one or more photodetectors configured to receive and measure the red light and the infrared light reflected off a vein of the patient, thereby determining an absorption ratio of a fluid in the target site;
• and
• a display screen, the display screen being configured to display the absorption ratio.
