Description

Technical Field

[0001] The present application relates to the technical field of medical equipment, and in particular to a peripheral vascular puncture assist device. Background Art

[0002] For patients who are unable to cooperate with puncture (such as those who are unconscious, sedated with drugs, and children), the operator usually needs to fix the patient's limb by himself or others to help fix the patient's limb for puncture. Venous puncture is usually for collecting blood samples, placing intravenous catheters for intravenous medication, etc. Arterial puncture is usually for collecting arterial blood gas samples, placing arterial catheters for hemodynamic monitoring. Venous puncture is usually performed on the dorsum of the hand, forearm, dorsum of the foot, and ankle joint veins. Radial artery puncture is the first choice for arterial puncture, followed by dorsalis pedis artery puncture. The above sites are close to the joints and have strong mobility. During the puncture process, patients often have voluntary or involuntary contraction, resistance and other limb activities. Arterial and venous puncture operations require high technical skills of nurses, and the degree of cooperation of the patient is also one of the factors affecting the success of puncture.

[0003] In the prior art, for continuous intravenous drug administration and continuous invasive arterial hemodynamic monitoring, soft tube indwelling needles are used. The tube diameter is small and it is easy to be completely folded. Once the tube is folded, it will directly lead to the slowing down of intravenous infusion or no dripping of the intravenous fluid. For hemodynamic monitoring, the monitor cannot measure accurate data. In view of the above situation, intervention can be carried out by adopting straight fixation plates, etc., but for long-term infusion treatment or 24-hour continuous monitoring, patient compliance is high. Traditional straight fixation plates are mostly suitable for children. Due to large individual differences, straight infusion fixation plates can fix the patient's wrist and ankle joints, but the tube still sticks to the wall and folds. It is often necessary to add pads to adjust the position of the limb to ensure the normal position of the tube. Utility Model Content
