上述采血装置所采血液存于真空采血管内，能够用于检验，优点是结构简单，但由于真空采血管与血气分析仪器并不适配，不能用于血气分析，使用具有局限性，可采用图2、图5和图6所示方式予以避免，具体如下：The blood collected by the above-mentioned blood collection device is stored in the vacuum blood collection tube, which can be used for inspection. The advantage is that the structure is simple, but because the vacuum blood collection tube is not compatible with the blood gas analysis instrument, it cannot be used for blood gas analysis, and its use has limitations. 2. The methods shown in Figure 5 and Figure 6 should be avoided, as follows:
采血装置包括采血装置主体和采血接头4；The blood collection device includes a blood collection device main body and a blood collection connector 4;
采血装置主体包括依次设置并通过管路6连接的第一端部接头1、带有肝素帽3的连接器2、阀门5、抽血筒7和第二端部接头8；The main body of the blood collection device includes a first end connector 1 , a connector 2 with a heparin cap 3 , a valve 5 , a blood pumping cartridge 7 and a second end connector 8 arranged in sequence and connected by a pipeline 6 ;
采血接头4包括采血接头主体、存血管49、连接管46和真空采血管接头47；采血接头主体包括底板41、外套42、穿刺杆45和存血管接头48；外套42和穿刺杆45均与底板41的一面连接，存血管接头48与底板41的另一面连接；外套42上设置有两个管路通过槽43；穿刺杆45位于外套42内；接头主体内设置有采血孔44，采血孔44由穿刺杆端面或侧面延伸至存血管接头48；存血管49、连接管46和真空采血管接头47依次连接，存血管49与存血管接头48可拆卸连接；Blood collection joint 4 comprises blood collection joint main body, storage tube 49, connecting pipe 46 and vacuum blood collection tube joint 47; 41 is connected to one side, and the storage tube joint 48 is connected to the other side of the base plate 41; two pipeline passage grooves 43 are arranged on the jacket 42; the puncture rod 45 is located in the jacket 42; Extend from the end face or side of the puncture rod to the storage tube joint 48; the storage tube 49, the connecting tube 46 and the vacuum blood collection tube joint 47 are sequentially connected, and the storage tube 49 and the storage tube joint 48 are detachably connected;
穿刺杆45插入肝素帽3，外套42套在连接器2外，管路6从管路通过槽43内通过；The puncture rod 45 is inserted into the heparin cap 3, the jacket 42 is set on the outside of the connector 2, and the pipeline 6 passes through the pipeline passage groove 43;
存血管接头48为能够与现有技术的空针乳头连接的接头，存血管49与存血管接头48连接的部分的形状与现有技术的空针乳头的形状相同。The storage tube joint 48 is a joint that can be connected with the empty needle nipple of the prior art, and the shape of the part where the storage tube 49 is connected with the storage tube joint 48 is the same as that of the empty needle nipple of the prior art.
存血管49内所存血液用于血气分析，由于存血管49与存血管接头48连接的部分的形状与现有技术的空针乳头的形状相同，与血气分析仪器是适配的。根据血气分析所需血量，可得出存血管49的容积最好为0.25～0.3mL。The blood stored in the storage vessel 49 is used for blood gas analysis. Since the shape of the part where the storage vessel 49 is connected to the storage vessel joint 48 is the same as that of the empty needle nipple of the prior art, it is compatible with the blood gas analysis instrument. According to the required blood volume for blood gas analysis, it can be concluded that the volume of the storage vessel 49 is preferably 0.25-0.3 mL.
上述两种采血接头4不限于与本实用新型的采血装置主体连接，也可与现有的肝素帽连接，进行采血。能够减少病人采血时的穿刺次数，减少病人痛苦，尤其是采血困难的儿科病人。由于存血管接头48为能够与现有技术的空针乳头连接的接头，第二种采血接头主体也可与现有空针配合使用。The above two blood collection joints 4 are not limited to be connected with the main body of the blood collection device of the present invention, and can also be connected with the existing heparin cap for blood collection. It can reduce the number of punctures for patients when taking blood, and reduce the pain of patients, especially pediatric patients who have difficulty in taking blood. Because the storage tube joint 48 is a joint that can be connected with the nipple of the empty needle in the prior art, the second blood collection joint main body can also be used in conjunction with the existing empty needle.
