Technical Field
The invention relates to the technical field of medical equipment, in particular to an arteriovenous puncture sensitivity-improving balloon indwelling needle.
Background
At present, patients with poor hemodynamics are always encountered during the puncture of a clinical arteriovenous indwelling needle, such as: the blood of patients with respiratory circulation failure and intravascular coagulation is often in a high-coagulation state and has low blood flow speed, the effective circulating blood volume of patients with excessive body fluid loss is insufficient, the peripheral circulation is poor, the blood vessels collapse, when the patients are directly punctured to construct a venous access or an arterial access, the indwelling needle is not punctured with negative pressure, the venous blood return is slow or is not returned, and when the arterial indwelling needle is used, the negative pressure-free blood return is slow, so that the puncturing sensitivity and accuracy are influenced. The puncture is failed, and the rescue time of the patient is delayed.
However, when the arteriovenous indwelling needle is clinically used, the needle is punctured by a syringe and then is sucked to produce negative pressure, the syringe is used for continuously keeping the influence of the negative pressure, so that one operator cannot complete the operation, the negative pressure sucked by the syringe is too large to damage local tissues and the needle mouth adheres to the wall, the pressure is too small to play a role, the puncturing difficulty is increased, the stability is low, and the safety is low.
Therefore, we propose a arteriovenous puncture sensitivity-enhancing balloon indwelling needle so as to solve the problems proposed in the above.
