技术领域Technical Field
本实用新型涉及医疗用具技术领域，更具体地涉及一种密封性好的采血管。The utility model relates to the technical field of medical appliances, and more specifically to a blood collection tube with good sealing performance.
背景技术Background Art
采血管是一种医用器材，用于采集血液样本或输液补液。常见的采血管有不同颜色的标签，标志着其用途和大小。采血管是由采血管体、采血针头和针套、橡胶塞和塑料盖、标签以及抗凝剂组成。Blood collection tubes are medical equipment used to collect blood samples or infuse fluids. Common blood collection tubes have labels of different colors, indicating their purpose and size. Blood collection tubes are composed of blood collection tube bodies, blood collection needles and needle sleeves, rubber stoppers and plastic caps, labels, and anticoagulants.
然而现有的采血管密封性较差，当需要对采血管进行使用时，将采血针头分别插入到患者的静脉血管和密封塞内，在采血管的负压作用下血液通过管道进入到采血管内储存，采血针头插入到橡胶塞内时会产生一个孔洞，当对患者抽血完成后，需要将采血针头取出，由于采血针头产生的孔洞难以保持采血管内部的密封性，容易导致采血管内部的血液与空气接触，造成血液受到污染，产生变质，降低了血液检测的准确性。However, the existing blood collection tubes have poor sealing performance. When the blood collection tube needs to be used, the blood collection needle is inserted into the patient's vein and the sealing plug respectively. Under the negative pressure of the blood collection tube, blood enters the blood collection tube through the pipeline and is stored in the blood collection tube. A hole is generated when the blood collection needle is inserted into the rubber plug. After the blood is drawn from the patient, the blood collection needle needs to be taken out. Due to the hole generated by the blood collection needle, it is difficult to maintain the sealing performance inside the blood collection tube, which can easily cause the blood inside the blood collection tube to contact with the air, causing the blood to be contaminated and deteriorate, thereby reducing the accuracy of blood testing.

The end of the connecting rod 232 away from the mounting seat 231 is fixedly connected to a clamping rod 233. Both sides of the outer wall of the blood collection tube body 1 are fixedly connected to a fixing block 13, and the fixing block 13 is clamped with the clamping rod 233. When in use, the connecting rod 232 is held and rotated on the mounting seat 231. The clamping rod 233 fixed at the bottom end of the connecting rod 232 is moved out or fixed from the fixing block 13 as the connecting rod 232 rotates, which facilitates the opening or closing of the blood collection tube body 1 and improves the stability of the connection of the blood collection tube body 1.
本实用新型的工作原理：首先，当需要对采血管主体1进行使用时，操作人员握住固定环121上的防滑块122，将采血管主体1进行取出，将采血针头分别插入到患者的静脉血管、橡胶塞22以及橡胶塞22底端的闭合页214内，闭合页214随着采血针头的插入产生挤压，进行张开，在采血管的负压作用下血液通过管道进入到采血管主体1内储存，接着，当对血液采集完成后，将放置在闭合页214和橡胶塞22上的采血针头拔出，闭合页214随着采血针头的拔出立即闭合，对空气进行隔绝，防止空气通过橡胶塞22上的针孔处进入到采血管主体1内，握住密封盖211在连接环213的外壁进行转动，固定在密封盖211内部的内环212随着密封盖211的转动在连接环213的内壁上进行转动，对连接环213进行密封，防止空气进入到橡胶塞22上的针孔处，通过密封盖211、内环212、连接环213以及闭合页214的配合使用，能够确保采血管主体1的内部保持密封，防止空气通过橡胶塞22上的针孔处进入到采血管主体1内，最后，当需要对血液进行抽取时，握住连接杆232在安装座231上进行旋转，固定在连接杆232底端的卡杆233随着连接杆232的转动从固定块13内移出，握住盖体2在采血管主体1上进行旋转，将采血管主体1进行打开，对采血管主体1内的血液进行抽取。The working principle of the utility model is as follows: first, when the blood collection tube body 1 needs to be used, the operator holds the anti-sliding block 122 on the fixing ring 121, takes out the blood collection tube body 1, and inserts the blood collection needle into the patient's venous blood vessel, the rubber stopper 22, and the closing page 214 at the bottom end of the rubber stopper 22 respectively. The closing page 214 is squeezed and opened as the blood collection needle is inserted. Under the negative pressure of the blood collection tube, the blood enters the blood collection tube body 1 through the pipeline for storage. Then, when the blood collection is completed, the blood collection needle placed on the closing page 214 and the rubber stopper 22 is pulled out. The closing page 214 is immediately closed as the blood collection needle is pulled out to isolate the air and prevent the air from entering the blood collection tube body 1 through the pinhole on the rubber stopper 22. The sealing cover 211 is held and rotated on the outer wall of the connecting ring 213. The inner ring 212 fixed inside the sealing cover 211 rotates on the inner wall of the connecting ring 213 as the sealing cover 211 rotates, thereby sealing the connecting ring 213 and preventing air from entering the pinhole on the rubber stopper 22. The coordinated use of the sealing cover 211, the inner ring 212, the connecting ring 213 and the closing page 214 can ensure that the interior of the blood collection tube body 1 remains sealed and prevent air from entering the blood collection tube body 1 through the pinhole on the rubber stopper 22. Finally, when blood needs to be extracted, the connecting rod 232 is held and rotated on the mounting seat 231, and the clamping rod 233 fixed at the bottom end of the connecting rod 232 is moved out of the fixing block 13 as the connecting rod 232 rotates. The cover body 2 is held and rotated on the blood collection tube body 1 to open the blood collection tube body 1 and extract blood from the blood collection tube body 1.
最后：以上所述仅为本实用新型的优选实施例而已，并不用于限制本实用新型，凡在本实用新型的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本实用新型的保护范围之内。Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
