采血針爲什麽絕不能二次使用？背後的真相讓人細思極恐！

來源： | 發布日期：2025-09-10

在日常生活中，我們常常會遇到采血：無論是血糖監測、體檢還是疾病篩查，采血针都是不可或缺的小工具。但你是否也曾好奇：這麽細的一根針，爲什麽不能清潔後再次使用呢？?

答案其實很簡單，卻關系到健康與安全。接下來，仟龍就來揭開采血針“只用一次”的真正原因。

采血不能重复使用-封面

一、采血針爲什麽不能二次使用？

血液殘留風險：首次使用時，采血針會接觸血液，即使擦拭，仍可能殘留血液成分和潛在病菌。
材質結構變化：針尖在第一次穿刺後可能出現細微鈍化或變形，二次使用會影響穿刺精准度與穩定性。
一次性標准設計：采血針本身就是一次性醫療耗材，並未考慮重複使用後的安全性。

小知識： 采血針與注射針不同，它並非“消毒後可複用”的工具，而是嚴格限制一次性使用。

二、采血針重複使用會帶來哪些危害？

1. 交叉感染风险

如果同一根采血針被多個患者使用，不同個體間的病原體可能通过针头传播，引发交叉感染。这种风险不仅存在于患者之間，還可能從患者傳染給醫護人員，或反之，形成惡性循環。

2. 检测结果不准確

采血針在首次使用後可能受汙染或損傷，再次采集的血液樣本質量下降，導致檢測數據不准確。这会影响临床判断，甚至引发誤診或漏診。

3. 血管损伤风险

針尖若因重複使用而鈍化或變形，会增加血管损伤的概率。后果可能包括：炎症、瘢痕，甚至影響日常生活質量。

三、如何更安全地面對采血？

堅持一次一用：不圖省事，更不要嘗試“清洗後再用”。
正規渠道購買：選購符合醫療標准的采血針，避免劣質産品。
注意采血環境：保持清潔，必要時使用一次性手套，降低感染風險。

結論： 采血雖然只是一個小小的醫療操作，但任何環節的疏忽都可能埋下風險。記住：采血針只用一次，安全勝過僥幸。

But why, then, this ardent zeal to save the necks of the two traitors "whose roof this night--" etc.? Manifestly she was moved by passion, not duty; love drove her on; but surely not love for them. "No," I guessed in a reverent whisper, "but love for Ned Ferry." It must have been through grace of some of her nobility and his, caught in my heart even before I was quite sure of it in theirs, that I sat and framed the following theory: Ned Ferry, loving Charlotte Oliver, yet coerced by his sense of a soldier's duty, had put passion's dictates wholly aside and had set about to bring these murderers to justice; doing this though he knew that she could never with honor or happiness to either of them become the wife of a man who had made her a widow, while she, aware of his love, a love so true that he would not breathe it to her while this hideous marriage held her, had ridden perilously in the dead of night to circumvent his plans if, with honor to both of them, it could be done. The spiteful little ripple of laughter was hushed as Leona Lalage returned. There was a flush on her face and a glitter in her eyes that Lawrence did not fail to notice. A little sheaf of banknotes fluttered in her hands. "Go on," said Leona. "Nothing seems to be concealed from you. Now please tell me what happens next." By assuming this or any other well-proved example, and estimating larger or smaller shafts by keeping their diameters as the cube root of the power to be transmitted, the distance between bearings as the diameter, and the speed inverse as the diameter, the reader will find his calculations to agree approximately with the modern practice of our best engineers. This is not mentioned to give proportions for shafts, so much as to call attention to accidental strains, such as winding belts, and to call attention to a marked discrepancy between actual practice and such proportions as would be given by what has been called the measured or determinable strains to which shafts are subjected. Another sanctuary holds an idol made of seven metals mingled to a pale golden hue. The statue is loaded with jewellery of silver and precious stones. On its head is a fan-shaped diadem starred with rubies. The walls and columns, of a dull purple, are decorated with gaudy mosaic of scraps of looking-glass set in brass along the lines of the mouldings. Others of the troops were ordered in, and among them was Landor's. It had gone out for a twenty days' scout, and had been in the field two months. It was ragged and all but barefoot, and its pack-train was in a pitiable way. Weeks of storm in the Mogollons and days of quivering heat on the plains had brought its clothing and blankets to the last stages. He tried to make some sound himself, but his tongue was as hypnotized as his other muscles, and refused to obey his will. Yet at the moment he did not seem to care much. His wishes were as numb as his tendons and sinews. He became shadowly conscious of his comrades gathering around him, picking him up, carrying him back up the hill, and laying him down again. This relieved the sharp pain from the stone under his head; but when they laid him down again his head fell too low. He heard the murmur of their voices, and felt their hands searching his pockets for cartridges. The Sergeant turned back and looked at him attentively. "Does your Bible say that ere?" asked the rebel. Everybody did. Not that there's ever been a chance to use it. He looked into her face, then suddenly crimsoned—then paled, to flush again: "No, Reuben, I could never do anything but fight your schemes. I think you are wasting and spoiling your life, and there's no use expecting me to stand by you." "I don't ask for that to-night—all I ask is food and shelter, same as you'd give to a dog." Margaret had a brother—a monk in the abbey at Winchcombe, to whose care she was indebted for the instructions which had made her a skilful embroidress, and still more for the precautions which had preserved her opening beauty from the gaze of the self-willed Roland de Boteler. Though the daughter of a bondman, her services had never been demanded; and father John had ultimately removed her from Edith's roof to the little cottage already mentioned.
