Description
技术领域
本发明主要涉及手术洞巾的技术领域,具体涉及一种促进医疗手术血液导流的手术洞巾。
背景技术
手术洞巾,就是专门用于给患者特定部位做外科手术的手术单,在该手术单上带有为特定手术位置而开设的孔洞,外科手术师可以在这个预设好的孔洞部位进行手术。在现有的手术洞巾结构中,都是采用简单的单层式结构,即利用无纺布加工成单层布料结构,在再布料中间位置处裁剪一个手术圆形孔洞出来,这样的结构设计,能够极大的减少手术洞巾的成本,但是由于设计的结构简单,导致在手术过程中,无法实现其他的促进效果,比如,在圆形孔洞的手术位置处,由于是需要切开患者的肌肤,会造成患者大量出血,当手术衣不能够实现吸血导流现象时,就会造成血液积留在圆形孔洞周边,长时间下,会造成血液滴落的现象,当血液滴落回患者伤口处时,就会造成伤口的细菌感染等现象,进而对患者的身体健康造成具大的影响;基于此,就需要研制一种全新结构的手术衣,对吸附到洞孔周边的血液进行导流目的,实现避免出现血液滴落到伤口处的现象。
发明内容
本发明主要提供了一种促进医疗手术血液导流的手术洞巾,用以解决上述背景技术提出的,现有的手术洞巾结构单一,对吸附到手术洞孔周边的血液无法实现导流而导致血液滴落易发生伤口感染的技术问题。
本发明解决上述技术问题采用的技术方案为:
一种促进医疗手术血液导流的手术洞巾,包括手术洞巾本体,其特征在于,所述手术洞巾本体包括内导流层、抗戳破层和吸水层,所述抗戳破层对称设在导流层的两侧,所述吸水层对称设在抗戳破层的两侧;所述内导流层内导流线网,所述导流线网是由导流线编织而成,所述导流线是由PVC材料混合蜘蛛丝、MAPAH纤维丝和植物纤维丝制得。

进一步的,所述抗戳破层的加工材料包括PET涤纶、PP聚丙烯、Ag+、纳米氧化石墨烯片和植物纤维混合去离子水。
进一步的,所述抗戳破层内各材料质量含量如下:15%-30%重量份的PET涤纶、20%-30%重量份的PP聚丙烯、0.05%-0.1%重量份的Ag+、0.5%-0.8%重量份的纳米氧化石墨烯片和3%-5%重量份的植物纤维混合去离子水。
进一步的,加工所述导流线的各材料含量占比如下:20%-30%重量份的混合蜘蛛丝、10%-20%重量份的MAPAH纤维丝和30%-40%重量份的植物纤维丝。
进一步的,所述手术洞巾的加工方法如下:
S01:制取吸水层无纺布
AS-1:混合溶液的配制:将膜材料、海绵体材料、聚酯纤维、添加剂,逐一加入到去离子水中,充分搅拌,得到均匀的混合溶液;
AS-2:无纺布的制备:将上述步骤得到的混合溶液加入注射泵,调节喷丝头到接收装置的距离为8~18cm;启动装置进行静电纺丝,设置纺丝电压为10~35kV,纺丝溶液的流量为0.75~2.5mL/h,在接收装置上得到了无纺布,将收集到的无纺布在真空干燥箱中干燥24小时,得到干燥的复合无纺布;
S02:制取抗戳破层无纺布
AS-1:混合溶液的配制:将PET涤纶、PP聚丙烯、Ag+、纳米氧化石墨烯片、植物纤维,逐一加入到去离子水中,充分搅拌,得到均匀的混合溶液;
AS-2:无纺布的制备:将上述步骤得到的混合溶液加入注射泵,调节喷丝头到接收装置的距离为8~18cm;启动装置进行静电纺丝,设置纺丝电压为10~35kV,纺丝溶液的流量为0.75~2.5mL/h,在接收装置上得到了无纺布,将收集到的无纺布在真空干燥箱中干燥24小时,得到干燥的复合无纺布;
S03:制取内导流线网
AS-1:混合溶液的配制:将PVC材料混合蜘蛛丝、MAPAH纤维丝和植物纤维丝,逐一加入到去离子水中,充分搅拌,得到均匀的混合溶液;
AS-2:无纺布的制备:将上述步骤得到的混合溶液加入注射泵,调节喷丝头到接收装置的距离为8~18cm;启动装置进行静电纺丝,设置纺丝电压为10~35kV,纺丝溶液的流量为0.75~2.5mL/h,在接收装置上得到了无纺布,将收集到的无纺布在真空干燥箱中干燥24小时,得到干燥的复合无纺布;
S04:裁减
将步骤S01-S03得到的无纺布利用放置到裁减台上,按照指定规格裁减;
S05:复合
利用热压复合机将步骤S01得到的吸水层无纺布、S02得到的抗戳破层无纺布和步骤S03得到的内导流线网按照结构要求进行复合、冷却、压合定型。
进一步的,所述蜘蛛丝的处理工艺如下:将称取出的蜘蛛丝加入到去离子水溶液中,在混有蜘蛛丝的水溶液中插入正负极电击棒,通入50V-80V的电流,持续通电15min后即止,蜘蛛丝直径达到15-30nm,再将通电后的蜘蛛丝加入到氢氧化钠溶液中,将其PH值调节到7.8-9.3之间,浸泡0.5h小时以上,取出、烘干,备用。
进一步的,所述MAPAH纤维丝的加工工艺如下:称取二甲基亚砜,加入到去离子水中,混合搅拌,得粘稠状液体,在将粘稠状液体经过聚合加工成粘稠纺丝液,在经过拉丝形成凝胶纤维,经过热处理,形成无机纤维---PAAS纤维长丝,再在PAAS纤维长丝表面涂覆一层聚丙烯酸甲酯,形成MAPAH纤维。
与现有技术相比,本发明的有益效果为:
本发明的结构设计合理,加工方便,主要通过吸水层的作用,能够将血液吸附,并且血液被吸附后,就会渗透到内部的内导流层,血液进入到内导流层后,就会吸附到导流线网上,由于MAPAH纤维丝和植物纤维丝对对血液拥有较强的吸附性,内导流线就会将血液牢牢地吸附,被吸附的血液会顺着编织的导流线网顺流到手术洞巾的四周,因此,手术孔洞周边吸附的血液会顺着导流线网逐渐扩散到手术洞巾周边,从而,就会避免发生吸附后的血液在手术洞口造成积留,并且发生滴落而造成患者伤口被感染的技术问题。
