The invention relates to a peripherally inserted central venous catheter (PICC) puncture bed, and effectively solves the problems that existing puncture beds are inconvenient to cathetering appliances, arm support of patients and defecation of patients. The PICC puncture bed comprises a bed plate placed left and right; a fixed plate is fixed at the rear side of the bed plate in a vertical direction; a rib plate capable of swinging back and forth is hinged at the upper end of the fixed plate; a sliding sleeve is slidably connected with the fixed plate; the sliding sleeve is hinged with the ribplate through a connecting rod; a placing plate is fixed on the rib plate; the middle part of the bed plate is provided with a through groove which is through up and down; the through groove is internally and slidably connected with two base plates which can move towards or away from each other along the front-back direction; the bed plate is fixedly provided with a supporting block which is positioned right below the base plates; a supporting rod capable of moving up and down is slidably connected in the supporting block; a urine receiver with an upward opening is fixed at the upper end of the supporting rod; a first magnetic steel is arranged at the right side of the lower end of the supporting rod; and a second magnetic steel which is positioned at the right side of the first magnetic steel and has opposite polarity to the first magnetic steel is arranged in the upper part of the supporting block. The PICC puncture bed has the advantages of novel conception, ingenious structure, convenient operation and high practicability.
