一种压力输液设备用输液管路Infusion pipeline for pressure infusion equipment

技术领域technical field

本发明涉及医疗器材技术领域。具体地说是一种压力输液设备用输液管路。The present invention relates to the technical field of medical equipment. Specifically, it is an infusion pipeline for pressure infusion equipment.

背景技术Background technique

压力输液设备目前在临床上已广泛应用，特别是重症监护室，医护人员通过使用输液设备和输液管路，针对不同病人症状情况来设定相应的输液流速以及输液总量。Pressure infusion equipment has been widely used in clinical practice, especially in the intensive care unit. By using infusion equipment and infusion pipelines, medical staff can set the corresponding infusion flow rate and total infusion volume according to the symptoms of different patients.

往往医护人员在使用过程中发现实际输液速度与设定值相差较大，其原因通常由于输液管路材料本身导致。一般实际使用的输液管路材料为PVC，但PVC在长期受输液设备蠕动泵碾压使用过程中，易产生疲劳磨损、弹性降低，最终造成输液流速不稳定。两种不同材质的管路在接头处不易进行间接，当内部压力过大时有崩开的风险。中文专利文献号CN203898844U中公开的泵用输液器虽然使用硅胶材料作为蠕动泵管，“蠕动泵管路套在管路接头上，装配完毕后，可以在二者的配合处增加夹持部件”，但是其夹持部采用硬质塑料环形夹，需借助工具方可夹牢，加工过程中力量难以把控，可能会压伤泵管。同时常规输液管路进液端采用单纯的瓶塞穿刺器，用于穿刺输液瓶胶塞。但目前市面有部分大容量输液袋或营养液袋未配有易于穿刺的胶塞或其他相应连接机构，临床使用不便。主流输液器产品都配备有流量调节器，用作重力输液时调节滴数控制流量，而输液设备用输液管路通常由蠕动泵挤压压力控制流速，且普通流量调节器极易被接触而产生误操作，如果压力输液过程中误操作流量调节器，会造成流量误差或者阻塞误报警等异常情况。Often medical staff find that the actual infusion speed is quite different from the set value during use, and the reason is usually caused by the infusion pipeline material itself. Generally, the material of the infusion pipeline used in practice is PVC, but in the long-term use of PVC by the peristaltic pump of the infusion equipment, it is prone to fatigue and wear, the elasticity is reduced, and eventually the infusion flow rate is unstable. Pipes of two different materials are not easy to be indirect at the joint, and there is a risk of collapse when the internal pressure is too large. Although the infusion set for pump disclosed in Chinese Patent Document No. CN203898844U uses silicone material as the peristaltic pump tube, "the peristaltic pump pipeline is sleeved on the pipeline joint, and after the assembly is completed, a clamping part can be added at the matching place of the two", However, the clamping part adopts a hard plastic ring clamp, which requires tools to be clamped firmly. It is difficult to control the force during processing, which may crush the pump tube. At the same time, the liquid inlet end of the conventional infusion pipeline adopts a simple cork puncture device, which is used to puncture the rubber stopper of the infusion bottle. However, at present, some large-capacity infusion bags or nutrient solution bags on the market are not equipped with a rubber stopper or other corresponding connection mechanism that is easy to puncture, which is inconvenient for clinical use. Mainstream infusion set products are equipped with flow regulators, which are used for gravity infusion to adjust the number of drops to control the flow rate, while the infusion pipeline for infusion equipment is usually squeezed by a peristaltic pump to control the flow rate, and ordinary flow regulators are easily contacted. Misoperation, if the flow regulator is misoperated during the pressure infusion process, it will cause abnormal conditions such as flow error or blockage false alarm.
