Venous blood collection needle analysis and application of clinical nursing practice

Activity level, saving operating time, and to increase the passing rate of sample collection. Care workers in the blood is worth thinking about work and attention to one of the issues. I have a one-time use of disposable syringes and blood collection needles supporting disposable vacuum blood collection in clinical specimens of blood to make the analysis and used widely. A comparison and use of its comparative and uses are listed below. 1.1 Figure 1 How the blood is the most primitive method, which has the following several major drawbacks: high cost (the cost of scalp acupuncture and higher disposable syringe needle blood collection costs); easily lead to more disposable lancet blood sample hemolysis ...; blood collection process for a long time 【2】; more susceptible to blood contamination. Figure 11.2 Figure 2 How-to two-way connector for the connection of the scalp needle,[link widoczny dla zalogowanych], as shown in Figure 1, the difference is that needles can not demolish the scalp and connected with the infusion, and can only be used for venous blood collection, as series pipe, with Dosing in the closed and so on. However, blood transfusion and the separation step, is bound to increase once again the pain of patients, potentially increasing the psychological pressure of patients; and when encountered when there is less blood flow can not be connected to suction disposable syringes, syringe needles only penetrate through the adoption suction blood vessels, thus increasing negative pressure in vitro, but the possibility of increased hemolysis. Figure 2 A Figure 31.3 Figure 3 Operation Lancets soft fit, the use of negative pressure vacuum storage vessel in principle, the introduction of automatic quantification of the blood vessels in storage. Normal operation by intravenous infusion method process, the rubber sheath needle directly into the disposable vacuum blood stopper, through the automatic suction of blood into the test tube along the wall,[link widoczny dla zalogowanych], the first specimens were taken, after the first pumping enough blood and pull out the end of the needle tube fold, blood samples were left shaken, and then right hand to pull out scalp needle, needle stopper outer sheath with hemostasis. (1) After collecting blood samples for patients who required a transfusion, medical personnel may be after the discount end of the silicone tube and sealing rubber needle separation, quickly prepared and the separation of the scalp infusion needle connected to open the fluid adjustment valves, regulating the infusion speed, fixed fluid pipes. This process should pay attention to aseptic technique and operating speed of the silicone tube to prevent the lancet more than blood coagulation. Figure 1,2 How more significant advantages: reducing the number of patients with venous puncture, protect blood vessels and reduce the suffering of patients with multiple puncture to ease the patient's psychological stress. (2) act as a concatenation tube. If there are two kinds of liquid clinical need for transfusion and no incompatibility at the same time, can be disposable vacuum blood collection needles were inserted into 2 two bags of liquid, so that can play the role of serial control. Advantages: the first infusion in the use of a single tube without thread can still successfully execute correctly by your doctor. (3) temporarily to the liquid infusion dosing. Disposable vacuum blood collection needle end result of silicone rubber needle tube and sealed after the separation of the tail pipe size of just being able to meet the syringe, the needle through the blood dosing. After dosing, the sealing rubber liner and re-sets back to the needle, blood collection needle retention. Blood collection needles inserted into the liquid,[link widoczny dla zalogowanych], pay attention to the whole process of aseptic operations. Advantages: ① after dosing the liquid is still at a relatively sealed,[link widoczny dla zalogowanych], the liquid will not be re-dosing puncture leakage from the puncture site; ② For just another end of dosing and sealing of silicone rubber needle tube separated by the above method again the can. (4) when confronted by when there is less blood flow can be directly connected to suction disposable syringes, and you should avoid too much negative pressure pump to prevent hemolysis. 2 shortcomings 3f ~ Blood Sampling needle injection needle after the end of the blood are prone to mass, resulting in blood contamination or pollution-bed units. Therefore, the needle injection technique needs to be improved. At present, the author is for the study of. 3 Evaluation of soft-fit pin in the clinical application of blood, got the doctors,[link widoczny dla zalogowanych], nurses and patients alike. Disposable syringes disposable lancet for blood than patients more easily accepted by nurses in the use of disposable lancet operations less time, reducing the chance of contamination, but the amount of disposable syringes for blood is more accurate, therefore, in the application of soft-fit when blood lancet shall be in strict accordance with the scale of vacuum blood collection tube blood, to ensure the accuracy of specimen. Practice shows: Figure 3N shows a more flexible fit lancet for clinical work, more difficult to reduce the blood vessel puncture on patients, especially elderly and children, the suffering of patients, but also reduce the level of nurses working to save operating time and improve the specimen collection pass rate.
