Background
The venous indwelling needle is an infusion tool for venous transfusion, is suitable for patients needing long-term, continuous and intermittent transfusion, and consists of a stainless steel core, a soft outer sleeve and a plastic needle seat. When the puncture is performed, the outer sleeve and the needle core are penetrated into the blood vessel together, and after the sleeve is sent into the blood vessel, the needle core is pulled out, and only the soft outer sleeve is left in the blood vessel for transfusion.
The advantages that the frequency of frequent puncture can be reduced, the blood vessel of the patient is protected, and the pain of the patient is relieved; for the patient with operation, frequent administration is needed in the operation, and the left needle can keep a smooth venous channel at any time, thereby being convenient for first aid and administration; the infusion time of the patient is flexible and convenient, the infusion can be carried out at any time and stopped at any time, the comfort level of the infusion of the patient is enhanced, and the working efficiency of nurses is improved.
The intravenous puncture catheterization is a basic nursing operation technology which is mastered by operating room nurses, and the establishment of a good intravenous channel is a precondition for ensuring the safety of surgical patients and the normal operation of surgical anesthesia. However, most of operation patients clinically need to undergo fasted water forbidden for 6-8 hours before operation, some of the operation patients need to perform gastrointestinal tract preparation, preoperative radiotherapy and the like, and the factors cause dehydration of the body of the patient, insufficient blood vessels and vein spasm hardening, so that the difficulty of vein puncture is increased, and meanwhile, the trust degree of the patient to operating room nurses is reduced.
In clinical care work, such a state in which the body surface of a patient has no visible vein or is not touched to the vein due to various factors (obesity, frequent puncture, intravenous drug abuse, etc.), and thus a condition in which no venous access is established is called difficult venous access (difficult intravenous access, DIVA), is a common problem of operating room venipuncture. In the prior art, an operating room nurse can only judge to execute puncture operation by means of handfeel and experience, if judgment is inaccurate, if blood returns slowly due to the hypercoagulability state of blood, the nurse can be caused to take the state as puncture failure by mistake, and puncture is repeated. This is time consuming and painful for the patient and may even delay the surgical treatment of the patient. How to solve the problem of difficult peripheral venipuncture catheterization in operation is always the focus of nursing staff research
