The utility model discloses a cardiovascular expander, which comprises a guide tube, one end of which is provided with a handle, the other end with a guide head, the guide end of the guide tube is closed, the end of the guide tube handle is provided with an air inlet, and two cylindrical air bags are sleeved near the guide head on the guide tube. The two cylindrical air bags are of the same size and shape, and are arranged on the guide tube at series intervals. A through hole is arranged on the wall of the tube, and the circumferential uniform interval of the balloon is provided with a liquid guide hole, which is parallel to the air guide tube, and a radial dilator is arranged on the outer covering of the two balloons. The dilator tube is especially suitable for the situation where the blood vessels need to be dilated for a long time. The gap between the two balloons is arranged, and the liquid guide hole is arranged on the balloon, so that the blood circulation is smooth and the comparison can be completed at one time. Long blood vessel dilation, thereby alleviating patient pain, simple structure, easy to use.
【技术实现步骤摘要】
心血管扩张器
本技术涉及医疗设备,特别涉及一种心血管扩张器。
技术介绍
临床上给患者进行心血管扩张时,多数在患者心血管内安装支架或者球囊,但因为心血管管道比较细,手工装入支架或球囊比较困难,且扩张过程中完全阻断血液循环的话,易引起低血压、意识丧失、抽搐等症状,特别是对于血管堵塞较长的情况,在扩张过程中易使病人出现生命危险。
技术实现思路
有鉴于此,本技术的目的是提供一种心血管扩张器,在进行心血管扩张时,血液循环流畅,能最大程度减小对病人的伤害。本技术的目的是通过以下技术方案实现的:心血管扩张器,包括导气管,所述导气管一端设置手柄,另一端设置导向头,所述导气管导向头端封闭,所述导气管手柄端设置有进气口,所述导气管上临近导向头处套设有两圆柱形气囊,两圆柱形气囊大小、形状相同,且串联间隔设置在导向管上,所述气囊内导向管壁上设置有通孔,所述气囊周向均匀间隔设置有导液孔,所述导液孔与导气管平行,两气囊外共同套设有一径向扩张管。进一步,所述径向扩张管为褶皱的压缩管,所述压缩管上设置有通孔。进一步,所述径向扩张管为网状结构,相邻网孔之间通过褶皱的弹片连接。进一步,所述导向头为圆头。本技术的有益效果是:本技术的心血管扩张器,特别适应于需扩张血管较长的情况,两个球囊间成间隙设置,球囊上设置导液孔,使得在进行扩张操作时,血液循环流畅,能一次性完成较长血管的扩张,从而减轻病人痛苦,结构简单,使用方便。本技术的其他优点、目标和特征在某种程度上将在随后的说明书中进行阐述,并且在某种程度上,基于对下文的考察研究对本领域技术人员而言将是显而易见的,或者可以从本技术的实践中得到教导。本技术的目标 ...
