[0002] Arterial blood gas analysis is an index reflecting the acid-base state of body fluids and gas content in blood. The arterial blood collection sites include radial artery, brachial artery, femoral artery, and dorsalis pedis artery. To expose the artery, a paper roll is usually placed on the elbow and wrist, so that the hand is dorsiflexed, forming an arc of about 135°-155°, and then blood is drawn from the patient. The arm is at a bending angle for a long time and there is no response The support device may cause the patient to involuntarily move the arm, causing the needle to move

The invention discloses an arterial auxiliary blood taking device. The device includes a fixing plate. A rotating plate is rotatably connected with the fixing plate. A connecting column is arranged atthe joint of the fixing plate and the rotating plate. A clamping ring is arranged on the rotating plate corresponding to the connecting column. A sliding groove is arranged at the position corresponding to the clamping ring on the fixing plate. A clamping block is arranged in the sliding groove corresponding to the clamping ring. Gaskets are arranged on both the fixing plate and the rotating plate. The fixing plate and the rotating plate on one side of the gasket are provided with fixing belts. The fixing plate and the rotating plate on the other side of the gasket are provided with fixing holes corresponding to the fixing belts. The fixing plate and the rotating plate on the side surface of the fixing hole are provided with adjusting holes. The arterial auxiliary blood taking device adjusts the fixing and rotating plates to a certain angle, thereby supports the patient's arm. The patient's arm is then immobilized with a fixing band, which effectively prevents the patient's arm from moving when the blood is drawn.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to an arterial auxiliary blood collection device. Background technique [0002] Arterial blood gas analysis is an index reflecting the acid-base state of body fluids and gas content in blood. The arterial blood collection sites include radial artery, brachial artery, femoral artery, and dorsalis pedis artery. To expose the artery, a paper roll is usually placed on the elbow and wrist, so that the hand is dorsiflexed, forming an arc of about 135°-155°, and then blood is drawn from the patient. The arm is at a bending angle for a long time and there is no response The support device may cause the patient to involuntarily move the arm, causing the needle to move. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide an arterial assisted blood collection device, which can fix the patient'...
