Description

Arteriopuncture assistor

Technical Field

The utility model relates to the technical field of medical auxiliary equipment, in particular to an arterial puncture assistor.

Background

The collection of blood and gas in the radial artery is more difficult than that of venipuncture, and the skin of a puncture part at the position of 2cm above the palm wrist joint of the forearm is disinfected conventionally. The operator touches the artery along the radius bone with the index finger, middle finger and ring finger of the left hand, lifts the middle finger at the most obvious position of the pulsation, and fixes the skin insertion with the index finger and ring finger. In the traditional blood sampling site, the strongest radial artery is used as a fixed point for puncture, and the needle inserting point for blood sampling is determined by the feeling of an operator. The radial artery is thin, the beating point is in a cord shape, the pulse can be touched within a long period, and the blood sampling position needs to be carefully operated.

When a nursing staff performs radial artery puncture, the palm of a patient needs to be stretched outwards, the skin of a puncture position is tightened, the strongest part of the radial artery pulsation is fully exposed, the wrist of the patient is held up by the left hand of the nursing staff during the puncture, the patient needs to be highly matched when the patient performs the puncture by holding a needle by the right hand, the patient has high matching degree which is in direct proportion to the success rate of collecting the blood gas of the radial artery, if the strongest part of the radial artery pulsation cannot be fully exposed by the patient, the success rate of the puncture of a nurse can be reduced, the pain of the patient is increased, meanwhile, certain differences exist in operation methods of the nursing staff, and therefore, great risks exist in the puncture operation. Especially to the critically ill old patient, the relatively poor patient of limbs activity degree and the relatively poor patient of cooperation degree, when carrying out the blood gas collection, need two nurses, alone take a blood sample, the fixed patient hand of another person will increase nursing staff like this and drop into quantity. Therefore, an arterial puncture assisting device has been produced, which is used to fix the wrist of a patient to assist a medical staff in arterial puncture. However, the existing arteriopuncture assisting device is hard, so that the device is not suitable for patients with different hand sizes, and causes discomfort for the patients.
