Description

Fixation device for radial artery puncture

technical field

The utility model relates to the field of medical equipment, in particular to a fixing device for radial artery puncture.

Background technique

Radial artery blood gas collection is more difficult than venipuncture, and the skin at the puncture site 2 cm above the volar wrist joint of the forearm is routinely disinfected. The operator touches the artery along the radial head with the index finger, middle finger and ring finger of the left hand. The middle finger is placed at the most obvious pulsation point, the middle finger is raised, and the index finger and ring finger are used to fix the skin to insert the needle. In the traditional blood collection site, the strongest part of the radial artery is used as the fixed point for puncture, and the blood collection needle point is determined by the operator's feeling. The radial artery is thin, the pulsation point is cord-like, and the pulsation can be palpated in a long section, and the location of blood sampling needs to be carefully manipulated.

When the nurses perform radial artery puncture, they need to abduct the patient's palm, tighten the skin at the puncture site, and fully expose the part with the strongest radial artery pulse. During the puncture, the nurse holds the patient's wrist with the left hand and holds the needle with the right hand to perform the puncture. At this time, a high degree of patient cooperation is required. The high degree of patient cooperation is proportional to the success rate of radial artery blood gas collection. If the patient cannot fully expose the part with the strongest radial artery pulsation, the success rate of the nurse puncture will be reduced, the patient's pain will be increased, and the nursing There are certain differences in personnel operating techniques, so there is a great risk in puncture surgery. Especially for critically ill elderly patients, patients with poor physical activity, and patients with poor coordination, two nurses are required for blood gas collection, one for blood collection and the other for fixing the patient's hand, which will increase the number of nursing staff. .

In order to further standardize the operation of puncture surgery and improve the success rate of puncture, medical workers in the field have designed a variety of tools suitable for assisting radial artery puncture. Pad, and then place the patient's wrist on the infusion bag, with the palm up and the back of the hand down, effectively exposing the patient's wrist, which is beneficial to the doctor's puncture success rate. Although this method is simple and practical, the infusion bag is easy to move during use, and the comfort of its use is not high. On the other hand, different patients have different wrist sizes, especially female patients, whose wrists do not match and are not suitable directly on the infusion bag. Moreover, this kind of auxiliary tool table is simple, and it will appear a little cold in the cold winter, which is not conducive to the radial artery puncture.
