Technical Field
The invention belongs to the field of intelligent medical instruments, and particularly relates to an operation method and equipment for improving one-time success rate of superficial venipuncture and catheterization.
Background
Superficial venipuncture is the key operation of clinical venous blood collection, administration through the venous route and fluid infusion, and is basically completed manually by medical staff at present, and the success rate of one-time puncture is uneven. The result is that the medical efficiency is reduced, the pain of the patient is increased, and the serious patient even influences the harmony of doctor-patient relationship. Although the vein imaging device can be used for improving the identification degree of the vein and improving the success rate of venipuncture to a certain extent, the uncertainty of manual puncture still cannot be avoided. The existing automatic venous blood sampling equipment patent realizes the improvement of the success rate of venous puncture by positioning blood vessels and puncture needles and utilizing a mechanical arm to improve the fine degree of motion control of the puncture needle. However, human skin and subcutaneous soft tissue are soft tissues, the puncture needle tip firstly pushes the vein wall to move backwards before puncturing the vein wall, and only when the pressure in the vein is high enough, the front layer vein wall is not retracted or the puncture needle is sharp enough, the puncture speed is fast enough, and the puncture can be easily successful when the advance is stopped in time just before puncturing the front layer vein wall and not puncturing the back layer vein wall. When the device is used for venipuncture of patients with insufficient pressure in a blood vessel cavity, such as shock, puncture failure easily occurs, and therefore, one-time puncture success cannot be guaranteed. And the equipment is only designed for solving the problem of venipuncture blood sampling at present, does not have the function of vein catheterization, and cannot meet the requirement of clinical transfusion treatment.
