Description
技术领域technical field
本实用新型涉及一种医疗器具，特别是一种采血针。The utility model relates to a medical appliance, in particular to a blood collection needle.
背景技术Background technique
目前，根据2010版SOP标准要求：血常规、肾功能、血电解质(包括血钾、血钙、血磷、HCO3 -或CO2CP等)，建议每月检查1次。一旦发现异常应及时调整透析处方和药物治疗。血糖和血脂等代谢指标，建议有条件者每1～3个月检测1次；以及危重患者需及时留取血标本以便动态了解患者病情变化以方便医师及时调整患者的治疗方案，更好的提高患者生存质量。Currently, according to the 2010 version of the SOP standard requirements: blood routine, renal function, blood electrolytes (including blood potassium, blood calcium, blood phosphorus, HCO 3 - or CO 2 CP, etc.), it is recommended to check once a month. Once an abnormality is found, the dialysis prescription and drug treatment should be adjusted in time. Metabolic indicators such as blood sugar and blood lipids are recommended to be tested once every 1 to 3 months; and critically ill patients need to take blood samples in time to dynamically understand the changes in the patient's condition so that doctors can adjust the patient's treatment plan in time to better improve Patient quality of life.
一般的维持性血液透析内瘘穿刺患者需留取血标本时，血液透析患者行血液透析治疗前，在进行内瘘血管评估后，先行内瘘穿刺并判断内瘘穿刺是否通畅后，打开内瘘穿刺针的尾端，随即打开真空采血试管的橡皮塞，通过内瘘穿刺针软管引血至打开的试管内，此时真空采血试管已经不具备真空的作用了，既不方便，同时采血量也不准确，而且血液容易外漏污染护士的手，拔除的橡皮塞在回套的过程中也可能污染血液或者橡皮塞的紧密性不够，从而导致配送人员在血标本转运的过程中发生血液的丢失，从而影响血标本的检测，影响患者的治疗。When blood samples need to be taken from patients with maintenance hemodialysis internal fistula puncture, before hemodialysis patients undergo hemodialysis treatment, after evaluating the internal fistula vessels, the internal fistula puncture should be performed first to determine whether the internal fistula puncture is unobstructed, and then the internal fistula should be opened Open the rubber stopper of the vacuum blood collection test tube at the end of the puncture needle, and draw blood into the opened test tube through the internal fistula puncture needle tube. It is not accurate, and the blood is easy to leak and pollute the hands of the nurse. The removed rubber stopper may also pollute the blood or the rubber stopper is not tight enough, which will lead to blood leakage during the transfer of the blood sample. Lost, thus affecting the detection of blood samples and affecting the treatment of patients.

具体实施方式detailed description
下面结合附图和具体实施例，进一步阐明本实用新型，应理解这些实施例仅用于说明本实用新型而不用于限制本实用新型的范围，在阅读了本实用新型之后，本领域技术人员对本实用新型的各种等价形式的修改均落于本申请所附权利要求所限定的范围。Below in conjunction with accompanying drawing and specific embodiment, further set forth the utility model, should be understood that these embodiments are only used for illustrating the utility model and are not intended to limit the scope of the utility model, after having read the utility model, those skilled in the art will understand this utility model The modifications of various equivalent forms of the utility model all fall within the scope defined by the appended claims of the present application.
一种内瘘穿刺采血针，如附图1、4所示，包括试管穿刺针头1、软管2、连接器3、内瘘穿刺针4。软管2一端连接了试管穿刺针头1，另一端连接了连接器3，三者形成连通，连接器3外部带有保护罩7，保护罩7内部与内瘘穿刺针4末端外部设有匹配的连接螺纹，使用时将连接器3末端与内瘘穿刺针4末端对接，并通过螺纹进行连接，使连接器3与内瘘穿刺针4形成连通。保护罩7一方面是方便连接器3末端与内瘘穿刺针4末端对接后固定，同时也可以防止血液外漏。A blood collection needle for internal fistula puncture, as shown in Figures 1 and 4, includes a test tube puncture needle 1, a flexible tube 2, a connector 3, and an internal fistula puncture needle 4. One end of the hose 2 is connected to the test tube puncture needle 1, and the other end is connected to the connector 3, and the three are connected. The connector 3 has a protective cover 7 on the outside, and the inside of the protective cover 7 and the outside of the end of the internal fistula puncture needle 4 are provided with a matching To connect the thread, when in use, the end of the connector 3 is docked with the end of the fistula puncture needle 4, and connected through the thread, so that the connector 3 and the internal fistula puncture needle 4 are connected. On the one hand, the protective cover 7 is to facilitate the docking of the end of the connector 3 with the end of the internal fistula puncture needle 4 and fix it, and it can also prevent blood from leaking out.
对连接器3设置有防护结构，防止连接器在使用前受到污染，进而污染与其连接的内瘘穿刺针及血液。The connector 3 is provided with a protective structure to prevent the connector from being polluted before use, and further contaminating the internal fistula puncture needle and blood connected thereto.
如附图2所示，一种防护结构是设置单独的保护帽5，保护帽5套在连接器3末端进行封闭，使用时拔除保护帽，将连接器3末端与内瘘穿刺针4末端对接。As shown in Figure 2, a protective structure is to set a separate protective cap 5, which is set on the end of the connector 3 to seal it. When in use, the protective cap is pulled out, and the end of the connector 3 is docked with the end of the internal fistula puncture needle 4 .
如附图3所示，一种防护结构是设置与连接器3形成一体的膜片6，连接器3末端通过该膜片6封闭，使用时随时对膜片破口，防护效果更好。最好是将膜片5的位置设置于凹陷在连接器3末端内部，形成下沉的台阶状，而不是直接设置在连接器3末端端面，防止将膜片误操作破坏。使用时对膜片破口的方式，可以是通过外部工具刺穿膜片，也可以是在内瘘穿刺针末端设置凸起，当连接器末端与内瘘穿刺针末端对接时，直接将膜片刺穿。As shown in Figure 3, a protective structure is provided with a diaphragm 6 integrally formed with the connector 3, and the end of the connector 3 is closed by the diaphragm 6, and the diaphragm is breached at any time during use, so that the protective effect is better. It is better to place the diaphragm 5 in a recessed position inside the end of the connector 3 to form a sunken step, rather than directly on the end face of the connector 3 to prevent damage to the diaphragm by misuse. The way to break the diaphragm during use can be to pierce the diaphragm with an external tool, or to set a protrusion at the end of the internal fistula puncture needle. When the end of the connector is docked with the end of the internal fistula puncture needle, directly insert the diaphragm pierce.
