Description

Technical Field

[0001] The utility model relates to the technical field of medical treatment, in particular to an arterial blood sampling auxiliary pillow. Background Art

[0002] Arterial blood sampling is a basic technical operation that is commonly used in clinical practice. Drawing arterial blood for blood gas analysis can help us determine the acid-base balance and hypoxia in the patient's body, and is one of the important means of clinical diagnosis and treatment. Clinically, arterial blood sampling usually uses the radial artery, brachial artery, femoral artery, dorsalis pedis artery, etc., with the radial artery being the first choice, followed by the femoral artery. The most commonly used site for arterial blood sampling in clinical practice, and the one with the highest puncture success rate, is the radial artery. However, in actual operation, when performing radial artery blood sampling on patients, the patient needs to keep the upper limb slightly abducted, the palm facing forward, and the dorsiflexion position. Only in this way can blood be successfully collected from the radial artery of the patient's upper limb.

[0003] However, the existing arterial blood sampling devices have the following defects when in use: first, for comatose patients, it often requires the cooperation of multiple people to achieve radial artery blood sampling. A single person, especially when the patient is unaccompanied, cannot complete the radial artery blood sampling operation, which reduces the blood sampling efficiency; second, for patients with lower limb hemiplegia, since their feet are tilted to the outside, when blood is collected from the dorsal artery of the foot, the nurse often needs to bend over or lean back or others need to help the patient to straighten his foot before blood can be collected, which makes the nurse's waist easily damaged.

[0004] Based on the above defects, there is an urgent need to design an arterial blood sampling auxiliary pillow to achieve efficient and convenient arterial blood sampling operations for patients. Utility Model Content
