技术领域technical field
本发明涉及医疗器械领域，尤其涉及一种连续外周神经阻滞导管固定装置及其使用方法。The invention relates to the field of medical devices, in particular to a continuous peripheral nerve block catheter fixing device and a method for using the same.
背景技术Background technique
连续外周神经阻滞技术因其效果确切、并发症少、对生理干扰小等因素的存在，目前在临床上广泛应用于麻醉、术后镇痛和疼痛治疗等领域。现在临床常用的外周神经阻滞套件在穿刺成功后直接使用医用贴膜将导管粘于皮肤表面用于固定。对此常出现导管固定不牢固，导管脱出或者末端位移的现象，由此导致治疗效果消失，从而患者增加痛苦，医师不得已需要重新穿刺置管(患者费用增加)或更换治疗方式(加重工作量)。还有一部分医师采用皮下隧道的办法将导管固定于皮下，此种方法创伤较大，患者存在牵拉疼痛的症状，隧道的建立增加了患者感染的危险，对于需要长期治疗或者镇痛的患者这种办法还可能出现窦道的可能。此外这两种固定方法在最后都需要使用医用贴膜固定导管，但因为很多治疗的靶点位置是比较小的组织间隙，治疗浓度容量的限制，使得在很短的时间后，药液因为压力的原因会渗至皮肤表面，使得贴膜与皮肤分离，增加感染风险，导管脱出或位移几率加大。The continuous peripheral nerve block technique is widely used in the fields of anesthesia, postoperative analgesia and pain treatment because of its definite effect, few complications, and little interference to physiology. Now clinically commonly used peripheral nerve block kits directly use medical patches to stick the catheter to the skin surface for fixation after successful puncture. In this case, the catheter is often not fixed firmly, the catheter prolapses or the end is displaced, which leads to the disappearance of the treatment effect, which increases the pain of the patient, and the doctor has to re-puncture the catheter (increased patient costs) or change the treatment method (increased workload) . There are also some doctors who fix the catheter under the skin by using a subcutaneous tunnel. This method is more traumatic, and the patient has symptoms of traction pain. The establishment of the tunnel increases the risk of infection for the patient. For patients who need long-term treatment or analgesia This method may also have the possibility of sinus tract. In addition, both of these two fixation methods require the use of medical film to fix the catheter at the end, but because many treatment targets are relatively small tissue gaps, the concentration and capacity of the treatment are limited, so that after a short period of time, the liquid medicine will be lost due to pressure. The cause will seep to the surface of the skin, causing the patch to separate from the skin, increasing the risk of infection and increasing the chance of catheter prolapse or displacement.
