Abstract

The invention discloses a thoracentesis positioning device for respiratory physicians. The thoracentesis positioning device comprises a bed board, wherein stand columns are fixed to four corners at the bottom of the bed board through bolts, a first fixing block and a second fixing block are fixed to the bottom of the bed board through bolts, a first lead screw is built in the second fixing block,a fixing sleeve sleeves one end close to the first fixing block, of the first lead screw, and the fixing sleeve and the first fixing block are fixed through a bolt. Movable wheels can be rotated, so that the first lead screw rotates, a vertical rod is driven to move on one side of the bed board, and position adjustment in the horizontal direction can be performed; a hand wheel is rotated, so thatthe second lead screw rotates to drive a sliding sleeve to move, further, position adjustment in the width direction can be realized, and accurate determination of a puncturing position can be realized; and besides, when the thoracentesis positioning device is used, swaying is avoided, safety is improved, a user can rotate a third lead screw to enable a clamping block to slide in a movable groove,and a puncture needle device can be convenient to fix, dissemble and use.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a thoracentesis positioning device for respiratory medicine. Background technique [0002] Respiratory Medicine is a department generally set up in hospitals to diagnose and treat patients' respiratory diseases. Thoracentesis is often required for diagnosis and treatment of patients. [0003] Thoracentesis refers to the operation of entering the pleural cavity with a sterile needle through the skin, intercostal tissue, and parietal pleura. In the clinical work of respiratory medicine, thoracentesis is a relatively common and convenient method of diagnosis and treatment. If through the examination, it is found that there is fluid in the patient's pleural cavity, the fluid can be extracted through thoracentesis, and various examinations can be performed to find the cause of the disease. [0004] In the past, when medical staff performed thoracentesis on patients, the med...
