  • Publication number: 20250044224
    Abstract: A substance component detection apparatus and a method are provided to reduce absorption of an infrared signal by a window medium, thereby obtaining abundant fingerprint region signals. The apparatus includes: a sample pool, an infrared optical window, an infrared light source, and a detector. The infrared optical window has a first surface that faces an inner side of the sample pool and that is configured to be in contact with a to-be-detected substance, and a second surface exposed on an outer side of the sample pool. A protruding portion is formed between two adjacent grooves on the second surface, and any protruding portion has an incident surface and an emergent surface. An infrared signal emitted by the infrared light source is irradiated on the incident surface. The detector determines a component of the to-be-detected substance and/or content of the component.

  • Publication number: 20240341737
    Abstract: Disclosed are a method and control device for adjusting an opening size of a sampling window of a biopsy surgical device. The biopsy surgical device includes a motor, an outer cutter tube and an inner cutter tube. The outer cutter tube includes a sampling window on a side of the front end. The motor drives the inner cutter tube to move axially through a transmission mechanism, changing the axial relative position of the inner cutter tube and the sampling window. The method includes: obtaining an input instruction that includes a set value of an sampling window opening length; determining an axial movement distance of the inner cutter tube according to the current position of the inner cutter tube and the set value; calculating the number of rotations of the motor corresponding to the axial movement distance; and controlling the motor to rotate until the sampling window reaches the opening length.
