Description
技术领域technical field
本发明涉及医疗用品技术领域，特别是涉及一种一次性血液净化管路的固定器。The invention relates to the technical field of medical supplies, in particular to a fixer for a disposable blood purification pipeline.
背景技术Background technique
血液透析是肾功能衰竭患者肾脏替代治疗方式之一。血液透析通过将患者血液引流至体外，经过透析器，血液与含机体浓度相似的电解质溶液通过弥散、对流进行物质交换，清除患者体内代谢废物及多余的水分，从而维持患者体内电解质、酸碱平衡。在透析过程中，需将动静脉端管路进行相对固定，避免患者在治疗过程中牵拉血液净化管路，引起动静脉端管路的移动，进而避免引起机器报警、停泵导致体外血液的凝固、丢失；避免穿刺针、导管滑脱等不安全事件的发生。Hemodialysis is one of the renal replacement treatments for patients with renal failure. Hemodialysis drains the patient's blood out of the body, passes through a dialyzer, and exchanges substances between the blood and the electrolyte solution containing similar concentrations in the body through diffusion and convection to remove metabolic waste and excess water in the patient's body, thereby maintaining the electrolyte and acid-base balance in the patient's body . During the dialysis process, it is necessary to relatively fix the arteriovenous end line to prevent the patient from pulling the blood purification line during the treatment process, causing the movement of the arteriovenous end line, thereby avoiding machine alarms and stopping the pump to cause extracorporeal blood. Coagulation and loss; Avoid unsafe events such as puncture needles and catheter slippage.
目前临床上最常见的血液净化管路的固定方法有两种：一种是采用血管钳，另一种是使用粘条简单固定。然而，临床中使用的血管钳的材质是不锈钢，反复使用且自重较重，为保证单人单次使用，避免交叉感染，需每班患者使用结束后进行消毒灭菌。而采用粘条固定，则导致管路绝对固定，当遇到危重症、躁动患者时，牵拉管路，增加了管路或穿刺针滑脱的风险。At present, there are two most common methods of fixing the blood purification pipeline clinically: one is to use blood vessel clamps, and the other is to simply fix with sticky strips. However, the material of the vascular forceps used in clinical practice is stainless steel, which is used repeatedly and has a heavy weight. In order to ensure a single use by a single person and avoid cross-infection, it is necessary to disinfect and sterilize the patients after each shift. The use of sticky strips for fixation leads to absolute fixation of the pipeline. When encountering critically ill or agitated patients, the pipeline is pulled, which increases the risk of the pipeline or puncture needle slipping off.
如何设计一种结构简单，便于医护人员对血液净化管路的妥善固定，避免院内交叉感染，是本领域技术人员需要解决的问题。How to design a simple structure that is convenient for medical staff to properly fix the blood purification pipeline and avoid cross-infection in the hospital is a problem that those skilled in the art need to solve.

本发明的一次性血液净化管路的固定器中，下盖体200可通过黏贴件300进行固定，血液净化管路穿过下盖体200的下盖进管凹槽221和下盖出管凹槽222后，翻转上盖体100，使血液净化管路穿过上盖进管凹槽121和下盖进管凹槽221形成的进孔以及上盖出管凹槽122和下盖出管凹槽222形成的出孔，然后将锁扣130与卡口230卡接，使上盖体100和下盖体200形成一个盒体，则血液净化管路被限制在进孔和出孔中，使血液净化管路不会沿着进孔和出孔的径向，向外移动。In the fixer of the disposable blood purification pipeline of the present invention, the lower cover body 200 can be fixed by the adhesive member 300, and the blood purification pipeline passes through the lower cover inlet tube groove 221 of the lower cover body 200 and the lower cover outlet tube After the groove 222, flip the upper cover 100 so that the blood purification pipeline passes through the inlet hole formed by the upper cover inlet groove 121 and the lower cover inlet groove 221 and the upper cover outlet groove 122 and the lower cover outlet groove. The outlet hole formed by the groove 222, and then the lock 130 is engaged with the bayonet 230, so that the upper cover 100 and the lower cover 200 form a box body, and the blood purification pipeline is limited in the inlet hole and the outlet hole, The blood purification pipeline will not move outward along the radial direction of the inlet hole and the outlet hole.
由于血液净化管路一般为圆柱形，上盖进管凹槽121与下盖进管凹槽221均为半圆形，且尺寸相同；上盖出管凹槽122与下盖出管凹槽222均为半圆形，且尺寸相同，则进孔和出孔能够形成圆形。该结构便于血液净化管路穿过进孔和出孔，且便于血液净化管路在进孔和出孔中，沿着轴向移动。Since the blood purification pipeline is generally cylindrical, the inlet groove 121 of the upper cover and the inlet groove 221 of the lower cover are semicircular and have the same size; the outlet groove 122 of the upper cover and the outlet groove 222 of the lower cover Both are semicircular and have the same size, so the inlet hole and the outlet hole can form a circle. This structure facilitates the blood purification pipeline to pass through the inlet hole and the outlet hole, and facilitates the axial movement of the blood purification pipeline in the inlet hole and the outlet hole.
上盖进管凹槽121、下盖进管凹槽221、上盖出管凹槽122和下盖出管凹槽222的数量均相等，且数量均大于等于两个，上盖进管凹槽121与上盖出管凹槽122一一对应；下盖进管凹槽221与下盖出管凹槽222一一对应。该结构能够使每个进孔对应一个出孔，使不同的血液净化管路之间保持距离。The upper cover pipe inlet groove 121, the lower cover pipe inlet groove 221, the upper cover pipe outlet groove 122 and the lower cover pipe outlet groove 222 have the same number, and the number is greater than or equal to two. 121 is in one-to-one correspondence with the pipe outlet groove 122 of the upper cover; the pipe inlet groove 221 of the lower cover is in one-to-one correspondence with the pipe outlet groove 222 of the lower cover. This structure can make each inlet hole correspond to an outlet hole, and keep distances between different blood purification pipelines.
