Venous puncture device and puncture method

Abstract

The invention discloses a venous puncture device and puncture method. The venous puncture device comprises an arterial and venous ultrasonic apparatus, a puncture module, a negative pressure module and a control terminal, wherein the control terminal is electrically connected with the modules, and the negative pressure module is connected with the puncture module through a catheter. The arterial and venous ultrasonic apparatus is used for determining a puncture point. The puncture module is used for performing puncture at the puncture point under the control of the control terminal. The negative pressure module is used for monitoring the pressure of the catheter when the puncture module punctures the puncture point and sends a monitored pressure value to the control terminal. Negative pressure is pumped at the puncture point under the control of the control terminal. The control terminal is used for controlling the puncture module to puncture the puncture point, judges the puncture process according to the pressure value sent by the negative pressure module and controls the negative pressure module to form negative pressure or controls the puncture module to stop puncturing. By accurately positioning the puncture point, monitoring the pressure situation in the puncturing process and controlling puncture, the puncture accuracy and success rate are improved.

Description

technical field [0001] The invention belongs to the technical field of arteriovenous puncture, and in particular relates to an arteriovenous puncture device and a puncture method. Background technique [0002] Arteriovenous puncture is the most common catheterization procedure in medicine. A central venous catheter (Central Venous Catheter, CVC) is a catheter that is punctured through the skin into the central vein. Similarly, Peripherally Inserted Central Catheter (PICC) has developed into a safe and effective catheterization technique, which is widely used clinically due to its obvious advantages. Patients receiving chemotherapy and parenteral nutrition provide a painless infusion channel. CVC or PICC can provide direct and convenient venous access for various treatments, and can also be used to measure various physiological parameters; applicable departments include anesthesiology, emergency department, intensive care unit (Intensive Care Unit, ICU), surgery, Internal ...

AI Technical Summary

Problems solved by technology

[0003] At present, the traditional CVC and PICC puncture is a blind puncture method that relies entirely on the experience of medical staff. Complications, the main complications include infectious complications (catheter-related blood infection), thrombotic complications (such as catheter-related deep vein thrombosis) and mechanical complications (such as pneumothorax); and there are Defects such as long time-consuming, large local tissue damage, failure of puncture, abandonment of puncture, etc.
