AI Technical Summary
Technical Problem
Existing light distribution structures in medical pumps struggle to evenly distribute light over the entire inside and edge of a tube, limiting their effectiveness in detecting bubbles and blockages.
Method used
A light distribution structure with a specific configuration of reflective surfaces and a light guide member that directs light from a light source to the interior and edges of a tube, using reflective surfaces with defined angles and a light-shielding mechanism to ensure comprehensive illumination.
Benefits of technology
Enables efficient and compact light distribution to the entire area of the tube, enhancing detection of bubbles and blockages with improved light intensity and reduced unnecessary light interference.

Abstract
The present invention provides a compact light distribution structure, detection device, and medical pump that can distribute light from a light source to the entire interior and edge of a tube. [Solution] The light distribution structure is a light distribution structure that distributes light from a light source toward a tube, and comprises: a light receiving surface that receives light from the light source; a first reflecting surface that reflects light incident from the light receiving surface; a second reflecting surface that folds and reflects the light reflected from the first reflecting surface toward the first reflecting surface side; a third reflecting surface that forms a mountain shape with a first slope that reflects the light reflected from the first reflecting surface toward the tube side and a second slope that reflects the light reflected from the second reflecting surface toward the tube side; and an emitting surface that emits both the light reflected from the first slope and the light reflected from the second slope toward the interior and edges of the tube.
