Description

一种肿瘤化疗穿刺辅助装置 技术领域
本实用新型涉及医疗器械技术领域，具体为一种肿瘤化疗穿刺辅助装置。
背景技术
肿瘤(tumour)是指机体在各种致瘤因子作用下，局部组织细胞增生所形成的新生物(neogrowth)，因为这种新生物多呈占位性块状突起，也称赘生物(neop lasm)，根据新生物的细胞特性及对机体的危害性程度，又将肿瘤分为良性肿瘤和恶性肿瘤两大类，而癌症即为恶性肿瘤的总称。要提请注意的是，癌症与癌是两个不同的概念，癌指的是上皮性的恶性肿瘤，如由大肠黏膜上皮形成的恶性肿瘤称为大肠黏膜上皮癌，简称大肠癌。由皮肤上皮形成的称皮肤上皮癌，简称皮肤癌等等。所以，若医生说某某人患的是癌症，即表明患者长的是恶性肿瘤；若说某某人患的是胃癌，意思是患者的胃黏膜上皮形成的癌症，若说患者得的是胃肉瘤，则表明这种恶性肿瘤不是由黏膜上皮细胞所形成的，可能由平滑肌细胞恶变引起，或是属于胃的恶性淋巴瘤等。
在肿瘤患者的治疗过程中，化疗是治疗肿瘤的一种手段，在肿瘤患者的治疗过程需要定期对患者进行穿刺抽取患者的体液进行检验，然而对于处于晚期的肿瘤患者，有部分患者心理承受能力太弱，导致其脾气暴躁，经常不愿配合医护人员进行治疗，尤其是在做穿刺的工作时，他们经常暴力反抗，导致医护人员无法进行穿刺抽取患者的体液，有时在穿刺工作结束后，患者不配合，导致患者穿刺的部位发生出血现象，不利于患者的治疗，为此，提出一种肿瘤化疗穿刺辅助装置。

优选的，所述第二圆柱型通槽的内壁上开设有与所述筒体外部外螺纹相匹配的内螺纹，且所述第二圆柱型通槽的内径大于所述圆形压板的直径。
通过采用上述技术方案，使得筒体便于通过螺纹的方式安装在第二圆柱型通槽的内部，第二圆柱型通槽的内径大于圆形压板的直径，可保证圆形压板能够顺利通过第二圆柱型通槽与患者穿刺的部位进行接触。
优选的，所述基座的棱角处均为倒圆角结构。

具体的，如图1和2以及5和6所示，所述基座1的两侧面上对称固定安装有两个固定套5，每个所述固定套5的内部均穿插有扁平状布带6，所述扁平状布带6的两端均为自由端。
在将患者胳膊插入两个第一圆柱型通槽3的内部时，可方便的通过扁平状布带6将患者的手腕系住，可防止患者暴力反抗，可保证穿刺能够顺利的进行。
具体的，如图1和2以及5和6所示，所述第二圆柱型通槽8的内部还设有压迫单元7，所述压迫单元7包括外部带有外螺纹的筒体16，所述筒体16螺接在所述第二圆柱型通槽8的内部，且所述筒体16的上端为封闭端，所述筒体16的底端为开口端，且筒体16的底端固定安装有中心位置带有圆孔的端盖19，所述筒体16的内部从上至下依次活动安装有弹簧17和导向块18以及连接杆20，所述弹簧17的上端与所述筒体16的内顶壁相抵触，且所述弹簧17的底端与所述导向块18的上部相抵触，所述导向块18的底部与所述连接杆20的上端固定连接，所述连接杆20的底端穿过所述端盖19中心位置的圆孔与位于所述筒体16下方的圆形压板21的上部中心位置处固定连接。
在穿刺工作结束以后可通过旋转操作筒体16将压迫单元7螺接在第二圆柱型通槽8的内部，此时圆形压板21对患者穿刺的部位进行压迫，可有效防止患者穿刺的部位出血，从而使得该装置具备压迫止血的功能，实用性较好。
具体的，如图5所示，所述第二圆柱型通槽8的内壁上开设有与所述筒体16外部外螺纹相匹配的内螺纹，且所述第二圆柱型通槽8的内径大于所述 圆形压板21的直径。
使得筒体16便于通过螺纹的方式安装在第二圆柱型通槽8的内部，第二圆柱型通槽8的内径大于圆形压板21的直径，可保证圆形压板21能够顺利通过第二圆柱型通槽8与患者穿刺的部位进行接触。
具体的，所述基座1的棱角处均为倒圆角结构。
可防止基座1的棱角磕碰患者或者医护人员，从而使得该装置安全可靠。
工作原理：该肿瘤化疗穿刺辅助装置，弧形凹槽2用于容纳患者的腹部，两个第一圆柱型通槽3用于容纳患者的胳膊，第二圆柱型通槽8用作穿刺的通道，两组固定单元4用于将基座1固定在患者病床上，可通过横杆14操作螺纹杆11，进而利用圆板13顶紧病床床板的底部，进而将基座1固定在患者病床上，通过弧形凹槽2和两个第一圆柱型通槽3的束缚作用，可防止暴躁不安的患者乱动，导致无法进行穿刺抽取患者的体液，此外，通过将螺纹杆11的上端通过滚动轴承12安装在圆板13的底部内部，可使得在调节螺纹杆11的时候，圆板13不会随着转动，可防止圆板13刮伤患者病床床板的底部，从而使得该装置安全可靠；在穿刺工作结束以后可通过旋转操作筒体16将压迫单元7螺接在第二圆柱型通槽8的内部，此时圆形压板21对患者穿刺的部位进行压迫，可有效防止患者穿刺的部位出血，从而使得该装置具备压迫止血的功能，实用性较好。
使用方法：使用时，将基座1横跨患者的腹部，将两组固定单元4卡持在患者病床的床板两边上，然后通过横杆14操作螺纹杆11，进而利用圆板13顶紧病床床板的底部；将压迫单元7拆下，通过第二圆柱型通槽8对患者进行穿刺工作，在穿刺工作结束以后可通过旋转操作筒体16将压迫单元7螺接在第二圆柱型通槽8的内部，此时圆形压板21对患者穿刺的部位进行压迫，可有效防止患者穿刺的部位出血。
安装方法：
第一步、首先将立板22固定安装在基座1的底部，然后将横板9安装在立板22的底部，再将螺纹杆11贯通安装在立板22上，然后将螺纹杆11的上端均通过滚动轴承12安装在圆板13的底部内部；
第二步、安装固定套5，然后将扁平状布带6安装在固定套5的内部；
第三步、安装压迫单元7，按照附图5和6组装压迫单元7，然后将组装 好的压迫单元7螺接在第二圆柱型通槽8的内部即可。
尽管已经示出和描述了本实用新型的实施例，对于本领域的普通技术人员而言，可以理解在不脱离本实用新型的原理和精神的情况下可以对这些实施例进行多种变化、修改、替换和变型，本实用新型的范围由所附权利要求及其等同物限定。
