Description
技术领域
本实用新型涉及医学上教学模型的技术领域，尤其涉及一种会阴切开缝合的仿真教学模型。
背景技术
产妇在分娩时，为了使胎头顺利娩出，且不使外阴受到撕裂伤，往往需要将外阴切开，以减轻胎头对外阴的挤压。医学生和刚参加工作的医护人员想要学习这项技术，原先都是在临床上用病人来学习，靠看老师的现场操作和自己的实际操作来掌握这门技术。但随着社会进步和产妇维权意识的增强，在真实人体上进行会阴的切开及缝合的临床示教与练习已不可行。近几年来，各医学院校为了达到教学目的购置了橡胶缝合模型或购买新鲜猪肉进行教学，但教学效果均不尽人意。使用新鲜猪肉虽然缝合质感更接近人体组织，但猪肉同纱布一样只能平铺在操作台上，没有立体的体位，学生缝合的操作姿势与临床实际操作姿势有一定差距，操作难度降低。橡胶缝合模型不仅价格昂贵而且多次缝合后会留下针眼且易裂开；同时，橡胶还易老化变硬而无法再使用。
发明内容
本实用新型的目的是提供一种成本低、可操作性强、仿形效果好的会阴切开缝合的仿真教学模型。
为实现上述目的，本实用新型一种会阴切开缝合的仿真教学模型，其包括底板，底板中心设有圆形孔，底板表面套设有布套，布套上设有模拟会阴结构。
所述布套由三层以上的弹性布料组成，布套上对应底板的圆形孔处设有模拟会阴结构，布套中间设有会阴联合中线，会阴联合中线中部一侧设有一道4-5cm且与会阴联合中线成45°夹角的模拟会阴切口。
所述布套的模拟会阴切口的三层布料分别模拟粘膜层、肌肉层、皮肤层三层组织，中间模拟肌肉层的布料中设有海绵。该三层布料采用不同颜色，这样学生在分层缝合过程中不易搞错。中间模拟肌肉层的布料中设有海绵，从而使模拟会阴切口层次感强，更加形象；而且由于布套具有多层结构，便于学生对模拟会阴切口进行分层缝合方法的练习。
所述布套的结构还可以是：布套上对应底板的圆形孔处设有模拟产后阴道，布套在模拟产后阴道的一侧设有模拟会阴切口。这样使模拟会阴切口具有立体感，更接近真人。
所述模拟会阴结构下方设有肛门直肠布套，便于模拟会阴切口缝合后指导学生进行肛门指诊操作，使整个实验操作更完整。
所述底板背部设有可开合的支架，当需要携带时，可将支架与底板合拢，便于学生带回宿舍练习，节约实验室有限的练习空间。当需要进行操作时，将支架支起，从而使底板具有一定的斜度，可以更加形象地模拟产妇的正常会阴体位，使学生操作姿势与临床一致，从而加快了学生下临床实习时的上手速度，增加了学生的自信心。
采用本实用新型的会阴切开缝合的仿真教学模型，底板具有一定的斜度，可以更加形象地模拟产妇的正常会阴体位，复原了会阴部的解剖结构，仿形效果好，可操作性强；所采用的布套材料细腻，具有弹性，拆线后材料性能恢复良好，不易留下针眼，不易撕裂，可反复使用，成本低。
附图说明
下面结合附图和具体实施方式对本实用新型作进一步详细的说明：
图1为本实用新型会阴切开缝合的仿真教学模型使用实施例1布套的结构示意图；
图2为本实用新型会阴切开缝合的仿真教学模型使用实施例2布套的结构示意图；
图3为底板的结构示意图。
具体实施方式
如图1-3之一所示，本实用新型一种会阴切开缝合的仿真教学模型，其包括底板1，底板1中心设有圆形孔2，底板1表面套设有布套3，布套3上设有模拟会阴结构4。
实施例1
如图1所示，本实用新型的底板1上套设布套3，其套设的布套3结构可如下：所述布套3由三层以上的弹性布料组成，布套3上对应底板1的圆形孔2处设有模拟会阴结构4，布套3中间设有会阴联合中线31，会阴联合中线31中部一侧设有一道4-5cm且与会阴联合中线成45°夹角的模拟会阴切口5。
所述布套3的模拟会阴切口5的三层布料分别模拟粘膜层、肌肉层、皮肤层三层组织，中间模拟肌肉层的布料中设有海绵。该三层布料采用不同颜色，这样学生在分层缝合过程中不易搞错。中间模拟肌肉层的布料51中设有海绵，从而使模拟会阴切口5层次感强，更加形象；而且由于布套3具有多层结构，便于学生对模拟会阴切口5进行分层缝合方法的练习。
本实用新型采用以上的结构，复原了会阴部的解剖结构，在实验操作过程中，还能帮助学生复习盆底解剖，使学生从解剖基础上掌握了缝合的层次感。所述布套3材料细腻，具有弹性，拆线后材料性能恢复良好，不易留下针眼，不易撕裂，可反复使用，成本低。
实施例2
如图2所示，本实用新型的底板1上还可套设另一套布套3，其具体结构为：所述布套3上对应底板1的圆形孔2处设有模拟产后阴道8，布套3在模拟产后阴道8的一侧设有模拟会阴切口5。布套3、模拟产后阴道8及模拟会阴切口5用不同颜色的布料以示区别，这样使模拟会阴切口5具有立体感，更接近真人。
不管是实施例1中还是实施例2中，所述模拟会阴结构5下方设有肛门直肠布套6，便于模拟会阴切口5缝合后指导学生进行肛门指诊操作，使整个实验操作更完整。
如图3所示，所述底板1背部设有可开合的支架7，当需要携带时，可将支架7与底板1合拢，便于学生带回宿舍练习。当需要进行操作时，将支架7支起，从而使底板1具有一定的斜度，可以更加形象地模拟产妇的正常会阴体位，使学生操作姿势与临床一致，从而加快了学生下临床实习时的上手速度，增加了学生的自信心。
