技术领域technical field
本发明属于医疗器械领域，具体涉及一种用于混合血样和抗凝剂的采血器混匀装置，本发明还涉及一种自充盈式动脉采血器。The invention belongs to the field of medical devices, and in particular relates to a blood sampling device mixing device for mixing blood samples and anticoagulants, and also relates to a self-filling arterial blood sampling device.
背景技术Background technique
临床上经常需要从患者的桡动脉、前臂动脉、股动脉等部位进行动脉采血以进行血气分析。目前临床上使用的动脉采血器多为活塞推注式，如CN200920030045、CN201020554216等，这种采血器需要双手操作，采血的剂量难以准确控制，无法实现微量采血。另外，由于活塞推注式采血器的抗凝剂通常是直接涂在内壁上，抗凝剂的剂量和浓度也难以准确控制，造成血样抗凝效果较差，并且抗凝剂的剂量控制不好还会影响到血气分析结果的准确性。Clinically, it is often necessary to collect arterial blood from the patient's radial artery, forearm artery, femoral artery, etc. for blood gas analysis. At present, most arterial blood collection devices used clinically are piston injection type, such as CN200920030045, CN201020554216, etc. This kind of blood collection device needs to be operated by both hands, and the dosage of blood collection is difficult to accurately control, and it is impossible to realize micro-volume blood collection. In addition, since the anticoagulant of the piston push-injection blood collection device is usually directly applied on the inner wall, the dosage and concentration of the anticoagulant are also difficult to control accurately, resulting in poor anticoagulant effect of the blood sample, and the dosage of the anticoagulant is not well controlled. It will also affect the accuracy of blood gas analysis results.
目前，欧美国家的主流动脉采血器大多是利用动脉血管自身的压力，采用自充盈的方式，这种方式能准确控制采血量，但由于抗凝剂仍是直接涂在内壁上，抗凝剂的剂量仍未得到准确控制，而且抗凝剂溶解速度慢且在血液中难以分布均匀，常常导致血液凝固形成血栓，严重的还会导致采血管堵塞。At present, most of the mainstream arterial blood collection devices in Europe and the United States use the pressure of the arteries themselves and adopt a self-filling method. This method can accurately control the blood collection volume. The dose has not been accurately controlled, and the anticoagulant dissolves slowly and is difficult to distribute evenly in the blood, which often leads to blood coagulation and thrombus formation, and in severe cases, blood collection tubes are blocked.
因此，如果能将抗凝剂制成药片，并制造出单独的混合血样和抗凝剂的装置，那么无论是活塞推注式还是自充盈式动脉采血器都无需再采用将抗凝剂涂在采血管内壁的方式，这将有利于严格控制抗凝剂的剂量，提高血样抗凝效果和血气分析的准确性。Therefore, if the anticoagulant can be made into pills and a separate device for mixing the blood sample and anticoagulant can be manufactured, neither the plunger injector nor the self-filling arterial blood drawer needs to apply the anticoagulant on the This will help to strictly control the dose of anticoagulant, improve the anticoagulant effect of blood samples and the accuracy of blood gas analysis.
另外，由于现有的自充盈采血器尾端无进气通道，只能在注入血样时通过尾端透气孔内的透气不透液的密封膜排气，而无进气功能，当采血管内的血样注满时，密封膜被血液堵塞，采血管内无法进入空气，血样很难自动流出，取样操作极其麻烦，而且很容易污染血样。In addition, since the existing self-filling blood collection device has no air inlet channel at the tail end, it can only be exhausted through the air-permeable and liquid-impermeable sealing film in the air hole at the tail end when the blood sample is injected, and has no air intake function. When the blood sample is filled, the sealing membrane is blocked by the blood, the air cannot enter the blood collection tube, the blood sample is difficult to flow out automatically, the sampling operation is extremely troublesome, and it is easy to contaminate the blood sample.

具体实施方式Detailed ways
下面通过具体实施例对本发明进行详细地说明。The present invention will be described in detail below through specific examples.
实施例1Example 1
图1式出的是一种自充盈式动脉采血器，包括采血管2和设在采血管2末端的硅胶塞3，所述硅胶塞3内设有与采血管2相连通的透气孔4，所述透气孔4内设有透气不透液的密封膜5。该结构是自充盈式动脉采血器的基本结构，采血时，血样在动脉血管压力的作用下注入采血管2，由于采血管2的尾端设有透气孔4，能够保证血样注入时采血管2的排气，使血样能顺畅注入，同时由于透气孔4内设有透气不透液的密封膜5，从而保证了血样注满时不会从尾端溢出。What Fig. 1 shows is a kind of self-filling arterial blood collection device, comprises blood collection tube 2 and the silica gel plug 3 that is arranged at the end of blood collection tube 2, and described silica gel plug 3 is provided with the vent hole 4 that communicates with blood collection tube 2, An air-permeable and liquid-impermeable sealing film 5 is arranged inside the air hole 4 . This structure is the basic structure of a self-filling arterial blood collection device. When blood is collected, the blood sample is injected into the blood collection tube 2 under the action of arterial blood pressure. Since the tail end of the blood collection tube 2 is provided with a vent hole 4, it can ensure that the blood collection tube 2 Exhaust, so that the blood sample can be injected smoothly, and because the vent hole 4 is provided with a gas-permeable and liquid-tight sealing film 5, thereby ensuring that the blood sample will not overflow from the tail when it is filled.
普通的自充盈式动脉采血器是采用浸泡-干燥的方式将抗凝剂如肝素钠涂覆在采血管2的内壁，由于抗凝剂的剂量不容易控制，我们专门设计了一种采血器混匀装置1，该装置的结构如图2所示，它包括两端开口的柱状混匀池本体11，所述柱状混匀池本体11的一端开口处设有采血针连接座12，所述柱状混匀池本体11的另一端开口处设有采血管连接座13，所述柱状混匀池本体11的内壁设有肝素抗凝片14，所述柱状混匀池本体11的内部设有金属混匀球15。所述采血管2与所述采血管连接座13连接。Ordinary self-filling arterial blood collection device is to apply anticoagulant such as heparin sodium on the inner wall of blood collection tube 2 by soaking and drying. Since the dose of anticoagulant is not easy to control, we specially designed a blood collection device mixing Homogenizing device 1, the structure of which is shown in Figure 2, it includes a columnar mixing pool body 11 with two openings, one end opening of the columnar mixing pool body 11 is provided with a blood collection needle connection seat 12, the columnar The other end opening of the mixing tank body 11 is provided with a blood collection tube connection seat 13, the inner wall of the columnar mixing tank body 11 is provided with a heparin anticoagulant sheet 14, and the inside of the columnar mixing tank body 11 is provided with a metal mixer. Uniform 15. The blood collection tube 2 is connected to the blood collection tube connecting seat 13 .
采血时，将采血针安装在采血针连接座12上并放在采血部位上，由于柱状混匀池本体11内设有金属混匀球15，迫使血液改变流动方向，从金属混匀球15的外围向柱状混匀池本体11的内壁流动，从而冲刷肝素抗凝片14，促使其快速溶解。同时血液还带动金属混匀球15在柱状混匀池本体11内转动，从而搅拌肝素抗凝片14与血液混合均匀。When taking blood, install the blood collection needle on the connection seat 12 of the blood collection needle and put it on the blood collection site. Since the metal mixing ball 15 is arranged in the columnar mixing pool body 11, the blood is forced to change the flow direction, and the The periphery flows toward the inner wall of the columnar mixing tank body 11, thereby flushing the heparin anticoagulant tablet 14 and promoting its rapid dissolution. At the same time, the blood also drives the metal mixing ball 15 to rotate in the columnar mixing pool body 11, thereby stirring the heparin anticoagulant tablet 14 and mixing the blood evenly.
所述柱状混匀池本体11的内部还设有涡流片16，所述涡流片16位于采血针连接座12的末端。涡流片16的第一个作用是支撑金属混匀球15，防止其堵在采血针的出液口上阻碍血液进入柱状混匀池本体11；涡流片16的第二个作用是使血液在柱状混匀池本体11内形成涡流，能更好地冲刷肝素抗凝片14，使其溶解速度更快，混合更加均匀。The inside of the columnar mixing tank body 11 is also provided with a vortex sheet 16 , and the vortex sheet 16 is located at the end of the blood collection needle connection seat 12 . The first function of the vortex sheet 16 is to support the metal mixing ball 15, preventing it from blocking the liquid outlet of the blood collection needle and hindering the blood from entering the columnar mixing pool body 11; the second function of the vortex sheet 16 is to make the blood mix in the columnar A vortex is formed in the uniform pool body 11, which can better wash the heparin anticoagulant tablet 14, make it dissolve faster and mix more uniformly.
所述采血管连接座13为硅胶套，可以插入不同规格的采血管2。The blood collection tube connection seat 13 is a silicone sleeve, which can be inserted into blood collection tubes 2 of different specifications.
所述肝素抗凝片14是按以下方法制备的：将厚度为0.5～2mm的纤维布浸泡在浓度为1～10mg/ml的肝素钠溶液中，取出烘干，然后分切成片。采用该方法制备的肝素抗凝片性质最稳定，溶解效果最好。The heparin anticoagulant tablet 14 is prepared according to the following method: soak a fiber cloth with a thickness of 0.5-2 mm in a heparin sodium solution with a concentration of 1-10 mg/ml, take it out and dry it, and then cut it into slices. The heparin anticoagulant tablet prepared by this method has the most stable properties and the best dissolution effect.
所述金属混匀球15的直径小于采血管2的内直径。当采血管2内注满血样时，可通过振摇，使金属混匀球15进入采血管2搅拌血样，混匀效果更佳。The diameter of the metal mixing ball 15 is smaller than the inner diameter of the blood collection tube 2 . When the blood collection tube 2 is filled with blood samples, the metal mixing ball 15 can enter the blood collection tube 2 to stir the blood samples by shaking, and the mixing effect is better.
试验结果表明，采用以上混匀装置后，能够很准确地控制血样中抗凝剂的含量，使普通采血或微量采血都不会导致血液凝固形成血栓，采样成功率达100％，而且由于准确地控制了血样中抗凝剂的含量，使血气分析的结果更加准确。The test results show that after using the above mixing device, the content of anticoagulant in the blood sample can be accurately controlled, so that ordinary blood collection or micro blood collection will not cause blood coagulation to form thrombus, and the success rate of sampling is 100%. The content of anticoagulant in the blood sample is controlled, so that the result of blood gas analysis is more accurate.
需要强调的是，本实施例中的采血器混匀装置并非只能用于本实施例的自充盈式动脉采血器，理论上讲，凡是需要在血样中加入抗凝剂防止血液凝固的任何一种采血器都能使用该装置。It should be emphasized that the blood sampling device mixing device in this embodiment is not only applicable to the self-filling arterial blood sampling device in this embodiment. The device can be used with any blood sampler.
所述采血管2和采血器混匀装置1的外部设有套管6，所述套管6的两端分别与采血管连接座13和硅胶塞3连接。套管6的作用是使采血在密闭的条件下进行，防治血样污染，同时还使采血器成为一个整体，结构更加牢固，使用更加方便。A sleeve 6 is provided on the outside of the blood collection tube 2 and the blood collection device mixing device 1 , and the two ends of the sleeve 6 are respectively connected with the blood collection tube connection seat 13 and the silicone plug 3 . The function of the casing 6 is to make the blood collection under airtight conditions to prevent blood sample contamination, and simultaneously make the blood collection device as a whole with a firmer structure and more convenient use.
由于现有的自充盈式采血器尾端无进气通道，当采血管2内的血样注满时，密封膜5被血液堵塞，采血管2内无法进入空气，血样很难自动流出。因此，我们还在硅胶塞3内设了一个用于给采血管2通气的进气阀栓7，该进气阀栓7既可以为螺杆式，也可以为按压式，它的具体结构是本领域技术人员都能掌握的常规技术，本文不再赘述，本实施例所采用的进气阀栓7为按压式，所述透气孔4位于进气阀栓7内。Since the tail end of the existing self-filling blood collection device has no air inlet channel, when the blood sample in the blood collection tube 2 is filled, the sealing film 5 is blocked by blood, and air cannot enter the blood collection tube 2, so it is difficult for the blood sample to flow out automatically. Therefore, we have also set up an intake valve plug 7 for ventilating the blood collection tube 2 in the silica gel plug 3. This intake valve plug 7 can be a screw type or a push type, and its specific structure is the present invention. Conventional techniques that can be mastered by those skilled in the art will not be repeated here. The air intake valve plug 7 used in this embodiment is a push type, and the air vent 4 is located in the air intake valve plug 7 .
当需要将采血管2内的血样进行贮存或进行血气分析时，将进气阀栓7按下，进气阀栓7与硅胶塞3之间就能形成气流通道，该气流通道与采血管2相连通，当采血管2垂直放置并且硅胶塞3一端向上时，采血管2内的血样在上端气压和重力的作用下能顺利自动流出。松开进气阀栓7以后，它会在硅胶塞3的弹力作用下自动复原，气流通道关闭。When it is necessary to store the blood sample in the blood collection tube 2 or perform blood gas analysis, the air inlet valve plug 7 is pressed down, and an airflow channel can be formed between the air inlet valve plug 7 and the silica gel plug 3, and the air flow channel and the blood collection tube 2 When the blood collection tube 2 is placed vertically and one end of the silicone plug 3 is upward, the blood sample in the blood collection tube 2 can flow out smoothly and automatically under the action of air pressure and gravity at the upper end. After the air intake valve plug 7 is released, it will automatically recover under the elastic force of the silica gel plug 3, and the air flow channel will be closed.
