A cervical sampling brush includes a sampling head and a handle, the sampling head is provided with a brush, the sampling head and the handle are provided with an inner chamber, the sampling head is provided with a plurality of blood conduction grooves which are the same as the axial direction of the head and separate the brush from several large blocks on the lateral wall of the sampling head, and the outer surface of the sampling head is provided with a layer from the root of the brush. Tear up the bristles along the brush from the root to the head and fill the stem with a sponge corresponding to the blood conduction trough. The lumen in the stem is communicated with the lumen in the sampling head. The sponge is exposed to the lumen in the sampling head and does not touch the wall of the lumen in the sampling head. The blood conduction trough can make the secretory mucus mixed with blood into the inner chamber while conducting blood. In addition, the tissue cells on the brush hair can be pulled out by the setting of the blood conduction trough, and the whole sampling head does not need to be taken down and loaded into the cell preservation solution, which is convenient and effective, and avoids mixing with more other materials. Matter and interference.
【技术实现步骤摘要】
宫颈取样刷
本专利技术涉及一种取样刷,具体涉及宫颈取样刷,属于IPC分类第A61B
技术介绍
宫颈细胞学检查是宫颈病变筛查的最基本方法,即妇检时做的薄层液基细胞学检查(简称TCT),医生通过一个小小的刷子在宫颈上刷取细胞,然后通过图片和计算机辅助等方法进行检测,以早期发现宫颈异常细胞。HPV检测,跟细胞学检查的过程相似,也是利用一个小小的刷子来获取宫颈的组织和分泌物等样品来检测是否携带有HPV病毒。在上述获取组织细胞中,因步骤的需要,所取得的组织细胞会存在一定的干扰,主要来自于所采集的组织细胞会混有血液、分泌物和某些润滑剂,这样会影响检测的结果。现有中国专利公开号:CN2694904Y所公开的宫颈及颈管细胞取样器,该取样器设有器具外套管、器具插芯、海绵套、器具插芯插入器具外套管内,器具外套管头部为半橄榄形,半橄榄形的头部后面还有一小孔,器具插心的头部连接海绵套,使用时,头部上方的小孔能让人体自身流血或因操作触血通过小孔渗透一部分,但并不能解决血液多时的技术问题。另外如中国专利公开号:CN205144616U所公开的一种一次性宫颈取样器,则直接采用海绵做为取样接触的头部,吸收性能是比刷毛强,但同时吸收的血液与细胞样本极易混在一起。还有如中国专利公开号:CN203647388U所公开的吸入式子宫颈活体取样装置亦是如此,只不过采用了注射器作为一个负压产生源,但所吸入的血液跟细胞样本还是混在一海绵体上。
