    摘要： Provided is an IV flow controller which adjusts the amount of an IV material supplied to a patient through an IV tube and to which a flushing feature is added. The IV controller according to the present invention includes: a first body unit, a second body unit, a fixed roller, and a driving roller. The fixed roller is fixedly and rotatably arranged, and has a first gear unit and a second gear unit. The driving roller is accommodated such that a portion thereof is exposed, and the driving roller is moved along the lengthwise direction while controlling the flow of the IV when the exposed portion is turned. Also, in the flushing position, the driving roller rotates in cooperation with the first gear unit of the fixed roller across the IV tube so as to flush the latter. The second gear unit of the fixed roller may be configured so as to have a ratchet gear, and the second body unit has a pawl which meshes with the ratchet gear of the fixed roller in order to prevent reverse rotation. According to the present invention, flushing in the reverse direction is prevented by the ratchet gear, and thus medical accidents caused by reverse flushing can be prevented.

    摘要： A technique to encode a group of vectors by quantizing the group with each of a number of different codes (44) and selecting the quantization results which are most favorable. This technique may include providing several vectors to an encoder (40) of a communication system (20) and quantizing each of the vectors with a number of different codebooks (44) to generate a corresponding number of codeword sets with the encoder (40). The codeword sets are each representative of the vectors. Each of the codeword sets is evaluated by determining a corresponding distortion value. The codeword set with the lowest distortion is selected to encode the vectors based on this evaluation. The codebook (44) or sequence of codebooks (44) used to generate the selected codeword set may differ from one vector sample to the next to provide a sample adaptive coding scheme. Transmission of the encoded data to a decoder (50) of communication system (20) may also be performed where the original vectors are reconstructed.
