Description
Translated fromChinese技术领域technical field
本实用新型属于医疗器械技术领域，具体是涉及一种快速采血接头。The utility model belongs to the technical field of medical devices, in particular to a quick blood sampling connector.
背景技术Background technique
临床上有很多危重患者需要在使用留置针或头皮针开通静脉的同时进行抽血检验，而现有的操作通常是，先使用留置针或头皮针为危重患者开通静脉，再使用注射器经乳头连接留置针或头皮针进行抽血，最后打开采血试管的密封塞将血液注入采血试管里，这样操作较为繁琐，既增加了医务人员的工作量，又增加了医务人员的职业暴露风险。In clinical practice, many critically ill patients need a blood test while using an indwelling needle or scalp needle to open the vein, and the existing operation is usually to first use an indwelling needle or scalp needle to open the vein for critically ill patients, and then use a syringe to connect through the nipple. Indwelling needles or scalp needles are used to draw blood, and finally the sealing plug of the blood collection test tube is opened to inject blood into the blood collection test tube. This operation is cumbersome, which not only increases the workload of medical staff, but also increases the risk of occupational exposure of medical staff.

作为优选，所述钢针连接部的右端往外延伸设有紧配头，所述硅胶保护套的头部紧配在紧配头上，这样可以防止硅胶保护套由于意外原因脱离钢针而失去保护作用。Preferably, the right end of the steel needle connecting part is provided with a tight fitting head extending outward, and the head of the silicone protective sleeve is tightly fitted on the tight fitting head, so as to prevent the silicone protective sleeve from being detached from the steel needle due to accidental reasons and losing protection effect.
作为优选，所述手持部呈圆柱体状，其表面设有防滑条纹，便于护理人员抓握，防止发生意外情况。Preferably, the hand-held portion is in the shape of a cylinder, and the surface thereof is provided with anti-slip stripes, which is convenient for the nursing staff to grasp and prevents accidents.
临床上遇到一些危重患者的时候，使用留置针或头皮针为危重患者开通静脉后，使用本实用新型可以很方便地为患者抽血。抽血时，抓握住本实用新型的手持部，先将本实用新型的乳头连接部插接在留置针或头皮针的外接口内，再经手持部左端沉槽壁上的内螺纹将本实用新型螺接在留置针或头皮针的外接口上，这样本实用新型的乳头连接部与留置针或头皮针的外接口相连通且两者连接处密封，然后将采血试管插入保护套管的开口端头内，钢针的针体受压先后刺穿硅胶保护套和采血试管的密封塞，钢针的针体伸入到采血试管中，直接负压抽血，抽血完成后拔出采血试管即可，硅胶保护套回弹密封住钢针的开口，更换采血试管可以多次抽血。整个抽血操作一气呵成，钢针和血液均无外露，大大降低了医务人员的职业暴露风险，同时还减轻了医务人员的工作量。因此本实用新型具有结构简单、设计合理等特点。When encountering some critically ill patients clinically, after using an indwelling needle or a scalp needle to open a vein for the critically ill patient, the utility model can be used to draw blood for the patient conveniently. When drawing blood, grasp the hand-held part of the present invention, first insert the nipple connecting part of the present invention into the external port of the indwelling needle or scalp needle, and then connect the The utility model is screwed on the external interface of the indwelling needle or the scalp needle, so that the nipple connection part of the present invention is communicated with the external interface of the indwelling needle or the scalp needle, and the connection between the two is sealed, and then the blood collection test tube is inserted into the protective sleeve. In the open end, the needle body of the steel needle is pressurized to pierce the silicone protective sleeve and the sealing plug of the blood collection test tube successively. The test tube is enough, the silicone protective sleeve rebounds to seal the opening of the steel needle, and the blood collection test tube can be replaced for multiple times. The whole blood drawing operation is completed in one go, and neither the needle nor the blood is exposed, which greatly reduces the occupational exposure risk of medical staff, and also reduces the workload of medical staff. Therefore, the utility model has the characteristics of simple structure and reasonable design.
