TECHNICAL FIELD
[0001] The utility model relates to medical supplies technical field, concretely is a kind of adjustable radial artery fixing device. BACKGROUND
[0002] With the improvement of medical technology, the large-scale operations such as heart, brain and lung are increasing, and invasive arterial continuous pressure measurement can accurately and timely find hemodynamic fluctuations, providing reliable data for the diagnosis and treatment of patients. Radial artery puncture is the first invasive arterial continuous pressure measurement, and it is necessary to find a method to improve the success rate of radial artery puncture. The project is to improve the success rate of radial artery puncture, so as to improve work efficiency and reduce the failure rate of puncture, thereby reducing the harm to patients. The project has high production feasibility, can be reused, is practical and economical, and is worthy of clinical application. There are relatively few reports on the application of adjustable radial artery fixing device in clinic, and this research is based on this point, aiming to provide help for clinical operation.
[0003] Invasive arterial continuous pressure measurement is widely used in rescue of critically ill patients and large-scale operations such as heart, brain and liver, which can accurately and timely find hemodynamic fluctuations and guide medical staff to handle the condition in the first time, making up for the shortcomings of non-invasive cuff, such as continuous pressure measurement, data delay and inaccuracy. Radial artery is superficial, pulsatile and convenient for puncture and fixation, and is currently the preferred method for arterial puncture and catheterization. The common puncture method is to bend the patient's palm, pad a infusion bag under the wrist and fix the palm with tape to make the radial artery more clear. Although this method is simple and practical.
[0004] However, the infusion bag is easy to move during puncture, and the success rate of puncture is low due to the different sizes of patients' wrists and the different bending amplitudes of palms, and the incidence of complications increases significantly. After a failed puncture, medical staff need to press the puncture point for 5-10 minutes to stop bleeding, which not only causes physical and mental pain to patients, but also increases the work intensity of medical staff, greatly reducing the work efficiency.
[0005] Therefore, the skilled person in the art provides an adjustable radial artery fixing device to solve the problems raised in the background art. CONTENT OF THE UTILITY MODEL
