A kind of B-ultrasound central venous puncture auxiliary deviceTechnical field
The invention belongs to technical field of medical auxiliary equipment, specially a kind of B-ultrasound central venous puncture auxiliary dressIt sets.
Background technique
Ultrasonic examination has the characteristics that non-invasive, repeatability and accuracy, therefore has clinically obtained extensiveUsing, be not only able to the lesion of the substantial visceras such as early detection liver, spleen, pancreas, kidney, guidance interventional therapy and vascular puncture etc.Aspect also has apparent advantage, especially the patient for establishing central vein access is needed gradually to increase in recent years, including need bloodThe renal failure and poisoning patient of liquid purification, need the tumor patient etc. of chemotherapy, and ultrasound is known as " observable stethoscope ",Key effect is played.
But at present in the central vein of B-ultrasound (mainly jugular vein and femoral vein) puncture, often firstIt is checked with the probe of ultrasound machine in the corresponding position of body surface, is carried out after finding the target blood of quasi- puncture in skin surfaceLabel, then removes probe, and local skin is punctured along the label done before after carrying out disinfection, do not accomplished real-timeIt is operated under monitoring.Sometimes due to the factors such as part pressing, patient body position change, anesthesia cause blood vessel traveling to vary slightly,It is unsuccessful just to will appear puncture, generally requires to position and puncture repeatedly.It is worn moreover, requiring to sterilize again row after positioning again every timeThorn, increases the work difficulty of clinician and the pain of patient.In order to increase the science and accuracy of central venous puncture,It needs a kind of auxiliary device, clinician is assisted to carry out the overall process of central venous puncture under " direct-view ", therefore it is proposed thatA kind of B-ultrasound central venous puncture auxiliary device.
Summary of the invention
