Description
技术领域technical field
本实用新型涉及医疗器械，尤其涉及一种静脉输液用留置套管针。The utility model relates to a medical device, in particular to an indwelling trocar used for intravenous infusion.
背景技术Background technique
静脉输液用留置套管针对于需要在一段时间内连续输液的非常适用，因为其在一次穿刺后可以在静脉内保留多日，而且穿刺完成后钢针就被拔除，不用但因由于患者在套管针留置期间活动而导致静脉血管被刺穿。The indwelling sleeve for intravenous infusion is very suitable for those who need continuous infusion for a period of time, because it can remain in the vein for many days after a puncture, and the steel needle is pulled out after the puncture is completed. The venous vessel is punctured due to activity during catheter indwelling.
现有的静脉输液用留置套管如图3-5所示，其主要包括两部分，即针部10和套部20；针部10在第一管体的第一端形成有套管针本体，其有柔性材料制成，例如硅胶；第一管体的侧部连接有管路13，以进行药液输入；第一管体中部形成有橡胶塞；第一管体第二端形成有接口15；套部20第一端形成有插头，用于插入所述接口中，由此将针部10和套部20连接在一起，套部20外可滑动地套有圆圈状的钢针底座21，钢针底座21的连接杆穿过套部20的引导槽而插入套部20内；钢针11的第二端固定在里连接杆上；钢针的第一端穿过套部20的第一端、橡胶塞14、套管针本体12后从套管针本体12的第一端的前开口12a出延伸到外部。静脉穿刺时，钢针11和套管针本体12一起刺入患者的静脉血管中，然后通过操作钢针底座21使得钢针11回退而完全进入套管部20中，最后自针部10取下套部20，仅仅将针部10用胶布或贴膜固定在患者的身体上。The existing indwelling cannula for intravenous infusion is shown in Figure 3-5, which mainly includes two parts, namely a needle part 10 and a sheath part 20; the needle part 10 is formed with a trocar body at the first end of the first tube body , which is made of flexible material, such as silica gel; the side of the first tube body is connected with a pipeline 13 for liquid medicine input; the middle part of the first tube body is formed with a rubber stopper; the second end of the first tube body is formed with an interface 15. A plug is formed at the first end of the sleeve part 20 for inserting into the interface, thereby connecting the needle part 10 and the sleeve part 20 together, and the sleeve part 20 is slidably covered with a circular steel needle base 21 , the connecting rod of the steel needle base 21 passes through the guide groove of the cover part 20 and is inserted into the cover part 20; the second end of the steel needle 11 is fixed on the inner connecting rod; the first end of the steel needle passes through the second end of the cover part 20 One end, the rubber stopper 14, and the trocar body 12 extend from the front opening 12a of the first end of the trocar body 12 to the outside. During venipuncture, the steel needle 11 and the trocar body 12 are inserted into the patient's venous blood vessel together, and then the steel needle 11 is retracted by operating the steel needle base 21 to completely enter the cannula part 20, and finally the needle part 10 is taken out. The lower cover part 20 only fixes the needle part 10 on the patient's body with an adhesive plaster or a sticking film.
由于要保持几天时间，所以，在这几天中，患者活动后经常会引起套管针本体12的前开口12a触壁，即前开口12a抵靠在静脉血管的血管内壁上，这样，以后通过该套管针输液时，液体的输入就会不畅甚至无法输入。Owing to keep several days time, so, in these few days, the front opening 12a of trocar body 12 often can be caused to touch the wall after the patient's activities, that is, the front opening 12a leans against the blood vessel inner wall of the venous blood vessel, like this, in the future When infusing fluid through the trocar, the input of the fluid will be blocked or even impossible.
实用新型内容Utility model content
鉴于上述问题，本实用新型新型旨在提出一种静脉输液用留置套管针，其在套管针本体前端的开口触壁后，仍能保证药液畅通地输入静脉血管中。In view of the above problems, the utility model aims to provide an indwelling trocar for intravenous infusion, which can still ensure the smooth input of medicinal liquid into the venous blood vessel after the opening at the front end of the trocar body touches the wall.
本实用新型的静脉输液用留置套管针，其包括针部和套部，套部可拆卸地结合在针部的第二端；针部的第一端形成有套管针本体，套管针本体的第一端形成有前开口，用于药液的输出；所述套管针本体的侧部开设有至少一个侧开口，用于药液从侧方输出。The indwelling trocar for intravenous infusion of the utility model comprises a needle part and a cover part, and the cover part is detachably combined with the second end of the needle part; the first end of the needle part is formed with a trocar body, and the trocar The first end of the body is formed with a front opening for the output of the medical solution; the side of the trocar body is provided with at least one side opening for the output of the medical solution from the side.
优选地，所述至少一个侧开口为两个侧开口。Preferably, the at least one side opening is two side openings.
优选地，所述两个侧开口分别开设在所述套管针本体的相反两侧。Preferably, the two side openings are respectively opened on opposite sides of the trocar body.
优选地，自所述两个侧开口到所述前开口的距离不同。Preferably, the distances from said two side openings to said front opening are different.
本实用新型的静脉输液用留置套管针，不但在前端有前开口，在侧面还有侧开口，即使前端触壁受到阻挡，药液还可以从侧开口中顺利流出。The indwelling trocar for intravenous infusion of the utility model not only has a front opening at the front end, but also has a side opening at the side. Even if the front end is blocked from touching the wall, the medicinal liquid can flow out smoothly from the side opening.
