技术领域technical field
本发明属于医疗器械领域，尤其涉及一种静脉留置通路采血器。The invention belongs to the field of medical devices, in particular to a blood sampling device for indwelling veins.
背景技术Background technique
临床上，对病人血标本进行检验是一项重要的诊断及病情判断依据，尤其是重症病人，为准确掌握病人病情变化，适时调整治疗措施，往往需定时采血检查。目前临床多采用重新对病人末梢静脉穿刺采血的办法获得血标本，对于重症病人、有静脉留置通路病人和末梢循环欠佳，不具备外周末梢采血条件的病人往往采用已有的静脉留置通路，使用多个注射器采血。具体方法为：使用三个注射器。对静脉留置通路接头进行消毒后，用第一个注射器抽出大于两倍静脉留置通路容积的液体，弃去（因此段液体可能含有封管用的肝素等其他药物，及细菌污染的风险，不宜重新注入静脉留置通路）；接上第二个注射器，抽取5-10ml液体置于一旁（为了使静脉留置通路中残留的少量封管溶液尽可能的被抽出，以免影响血标本的检验结果）；接上第三个注射器，抽取所需要的血液标本，注入采血管内；再重新接上第二个注射器，将刚刚抽出的5-10ml液体注入静脉留置通路中。最后接上输液器继续输液治疗。有时为了简化操作，将第一个注射器抽取5-10ml液体弃去，再用一个注射器直接抽取血标本，如此会对病人体内血液造成医源性流失，影响病人预后。Clinically, the examination of blood samples of patients is an important basis for diagnosis and condition judgment, especially for critically ill patients. In order to accurately grasp the changes in the patient's condition and adjust treatment measures in a timely manner, regular blood sampling is often required. At present, blood samples are mostly obtained by puncture of the patient's peripheral vein again in clinical practice. For critically ill patients, patients with indwelling venous access, and patients with poor peripheral circulation who do not have peripheral peripheral blood collection conditions, the existing indwelling venous access is often used. Multiple syringes for blood collection. The specific method is: use three syringes. After sterilizing the venous indwelling access connector, use the first syringe to draw out the liquid that is more than twice the volume of the venous indwelling access, and discard it (therefore, the liquid may contain other drugs such as heparin for locking the tube, and the risk of bacterial contamination, so it is not suitable to re-inject intravenous indwelling access); connect the second syringe, draw 5-10ml of liquid and put it aside (in order to draw out a small amount of locking solution remaining in the intravenous indwelling access as much as possible, so as not to affect the test results of blood samples); connect The third syringe draws the required blood sample and injects it into the blood collection tube; then reconnects the second syringe and injects the 5-10ml of liquid just drawn into the intravenous indwelling access. Finally connect the infusion set and continue the infusion therapy. Sometimes in order to simplify the operation, 5-10ml of liquid is extracted from the first syringe and discarded, and then a blood sample is directly drawn with a syringe, which will cause iatrogenic loss of blood in the patient's body and affect the prognosis of the patient.
有研究证明，方法得当时通过静脉留置通路采集的血标本与外周末梢血标本检查结果一致，因此可以通过静脉留置通路采集血标本。而目前所采取的措施存在以下不足：多次更换静脉留置通路与注射器的接头，造成污染风险增加，增加整个操作过程中整个装置开放污染的几率。如减少一个步骤，将会造成病人体内血液的医源性流失，有失伦理道德和病人疗效。过程复杂，耗时较长，影响护士其他工作。过程复杂，消耗较多的医疗用品。基于以上，有必要发明一种专门针对静脉留置通路采血的采血器，使操作简化、科学、安全。Studies have shown that when the method is appropriate, blood samples collected through an indwelling venous access are consistent with peripheral blood samples, so blood samples can be collected through an indwelling venous access. However, the measures currently taken have the following disadvantages: multiple replacements of the joints between the intravenous indwelling access and the syringe, resulting in an increased risk of contamination, and increasing the probability of open contamination of the entire device during the entire operation. If one step is reduced, it will cause iatrogenic loss of blood in the patient's body, which will lose ethics and morality and curative effect of the patient. The process is complicated and time-consuming, which affects other work of nurses. The process is complicated and consumes more medical supplies. Based on the above, it is necessary to invent a blood collection device specially for blood collection through venous indwelling access, so that the operation is simplified, scientific and safe.
