Abstract
Description
Technical Field
[0001] The utility model relates to a medical appliance, in particular to a femoral artery puncture needle auxiliary fixing dressing. Background Art
[0002] In clinical work, blood gas analysis is an important means to understand the patient's respiratory function and acid-base balance. It is widely used in the diagnosis of hypoxemia and respiratory failure, acid-base balance diagnosis, and the selection of surgical indications. Blood gas analysis uses arterial blood samples, and the commonly used arteries for blood sampling are the femoral artery and the radial artery. For patients with cachexia caused by terminal cancer and other reasons, it is difficult to draw blood for testing in their superficial arteries such as the radial artery due to contracture of the inner diameter. The femoral artery has a large diameter and abundant blood circulation, and is often used as the puncture artery for blood gas analysis.
[0003] Clinically, the needle is usually inserted near the groin on one side, with the index and middle fingers of one hand touching the strongest part of the femoral artery to fix it, and the other hand holds a syringe to vertically pierce the artery between the two fingers and aspirate a blood sample. However, for novice medical personnel, since the needle needs to be fixed by two fingers during the needle insertion process, it is easy to injure the finger; the needle is easy to deviate during the needle insertion process and cannot be accurately inserted into the artery. Sometimes the operation needs to be repeated many times, which increases the pain of the patient.
[0004] At the same time, it requires high experience and level of the operator. Medical staff need multiple trainings to master the skills of femoral artery blood collection. Therefore, how to design an auxiliary tool to fix the blood collection tool and assist medical staff in operation can effectively reduce the operation requirements and reduce possible errors in the blood collection process.
