Description

一种颈部留置针固定装置 技术领域
本发明涉及医疗设备领域，尤其涉及一种颈部留置针固定装置。
背景技术
静脉留置针又称静脉套管针，其适用于间歇性、连续性或每日静脉输液治疗。留置针包括不锈钢的穿刺引导针芯和可以留置在血管内的柔软的导管，使用时将导管和针芯一起穿刺入血管内，当导管全部进入血管后，回撤出针芯，仅将柔软的导管留置在血管内从而进行输液治疗，而需要将接头部分固定于患者的输液的位置。
目前临床上传统固定留置针方式为使用多根橡皮胶布固定，过多的胶布与皮肤毛发相粘，单纯使用胶布由于数量过多在拔针撕胶布都会给患者带来疼痛，橡皮胶布使用时还经常会发生卷曲和移位，存在安全隐患。
发明内容
本发明的目的是克服现有技术的问题，提供一种颈部留置针固定装置。
本发明的一种颈部留置针固定装置，包括与颈部贴合设置的弹性弧形圈和分别设于弹性弧形圈两端的固定带，所述固定带上设有收缩连接件，所述固定带之间通过收缩连接件配合连接，所述弹性弧形圈上设有凹槽，所述凹槽内设有弹性限位卡条，所述弹性限位卡条分别与颈部留置针的针座贴合适配。
作为本发明的进一步改进，所述弹性弧形圈为带孔玻璃纤维、带孔硅胶或带孔高弹性聚脂材质的弹性弧形圈。
作为本发明的进一步改进，所述弹性弧形圈内侧设有防磨层，所述防磨层为硅胶、低压泡沫或高弹性聚脂材质的防磨层，所述弹性弧形圈与防磨层通过卯榫连接。
作为本发明的进一步改进，所述凹槽与弹性限位卡条通过卯榫连接。
作为本发明的进一步改进，所述固定带两面都设有收缩连接件，所述收缩连接件为魔术贴。
作为本发明的进一步改进，所述收缩连接件为软性磁铁片，所述软性磁铁片外设有棉布隔离层。
作为本发明的进一步改进，所述固定带穿设于弹性弧形圈两端并通过调节限位圈固定。
作为本发明的进一步改进，所述弹性限位卡条与凹槽开口处设有让位槽。
作为本发明的进一步改进，所述弹性限位卡条设有与针座轮廓相适配的让位槽。
本发明与现有技术相比，具有以下优点。
本发明的整体结构设计合理，各个部件相互配合使用能够稳固留置针，避免移位，消除安全隐患。
本发明弹性弧形圈能根据不同的使用者改变形状以贴合，通过固定带配合调节并通过收缩连接件将颈部留置针固定于颈部。由于弹性弧形圈上的凹槽内设有弹性限位卡条，弹性限位卡条分别与颈部留置针的针座贴合适配，弹性限位卡条能够变形并与针座贴合，从而固定留置针。
由于弹性弧形圈为带孔玻璃纤维、带孔硅胶或带孔高弹性聚脂材质的弹性弧形圈，带孔保证整体装置的透气性，避免对患者皮肤造成不适。由于弹性弧形圈内侧设有防磨层，所述防磨层为硅胶、低压泡沫或高弹性聚脂材质的防磨层，所述弹性弧形圈与防磨层通过卯榫连接。能够重复使用，弹性弧形圈消毒，而防磨层能够保证使用者的舒适感且通过卯榫配合可以拆卸替换。凹槽与弹性限位卡条通过卯榫连接可以拆卸替换。由于固定带两面都设有收缩连接件，收缩连接件为魔术贴或软性磁铁片，能够根据使用者的颈部的具体粗细调节固定，由于软性磁铁片外设有棉布隔离层能够保证患者的适用舒适度。固定带穿设于弹性弧形圈两端并通过调节限位圈固定，可以调节替换。弹性限位卡条与凹槽开口处设有让位槽，能够为留置针部件让出通道，保证使用效果。由于弹性限位卡条设有与针座轮廓相适配的让位槽，使得固定配合更紧密贴合。
