Description

High-pressure radiography syringe pipeline fixing device

Technical Field

The utility model belongs to the technical field of high-pressure radiography pipeline fixing, and particularly relates to a pipeline fixing device of a high-pressure radiography injector.

Background

CT/nuclear magnetic enhancement examination is a common examination technology for better diagnosis and treatment by rapidly injecting high-dose high-concentration high-osmotic pressure high-viscosity contrast agent through a high-pressure syringe by venous high pressure so as to increase the density difference between tissues and lesions. Currently, two types of high-pressure injectors are commonly used in inspection, namely a needle cylinder type high-pressure injector and a roller pump type high-pressure injector, and a straight tube high-pressure radiography injection pipeline system and a spiral spring type high-pressure radiography injector pipeline system are respectively used. Both pipeline systems need to be connected with a high-pressure-resistant indwelling needle which is reserved in advance by a patient for injecting contrast agent to complete enhancement examination. The puncture site of high pressure injection is mostly injected with contrast agent by elbow center, noble or head vein, the length of the pipeline part connected with the puncture site of the patient is generally about 1.8 meters, and the pipeline with a very long part can not be completely fixed by one person for one time, so that potential safety hazard exists.

The proper fixation of the section of the pipeline is not an effective method at present, and the section of the pipeline is usually fixed at the forearm of a patient by using an adhesive tape, and then the patient holds the pipeline in the hand for short time to inject the contrast agent to complete the enhanced examination. The simple adhesive tape fixation can not be properly fixed due to the problems of hair, sweat and the like, and the pipeline slipping is easily caused by tearing off. The patient can forcefully squeeze the pipeline due to factors such as tension in the process of examination, so that the injection speed of the contrast agent is influenced, and even the injection failure can not be completed due to the overlarge pressure of the pipeline. Meanwhile, as the patient cannot fully know the importance and the purpose of the pipeline in the inspection time, the pipeline is often loosened due to unintentional hands-off or excessive grasping in the inspection process, so that the pipeline is folded and dragged, and even the connected indwelling needle is shifted and pulled out in the blood vessel, so that the contrast agent is extravasated, and the inspection pain and damage of the patient are increased. Most patients with enhanced examinations are patients with end cancer or older age, and the condition of re-puncturing the blood vessel is poor, even affecting the subsequent diagnosis and treatment of the patient.

When the nuclear magnetism enhancement examination is carried out, the examination time of a patient is about half an hour, a syringe type high-pressure injector is adopted, a high-pressure radiography injection pipeline system is connected through a spiral spring-shaped connecting pipe, and the high-pressure radiography injection pipeline system is wound on the finger of the patient for fixing the pipeline conveniently. Therefore, unnecessary injuries such as skin temperature reduction and ischemia at the tail end of the limb can be caused by long-time winding and tightening of the pipeline. Whether CT or nuclear magnetic resonance examination is performed, there is a state in which the examination bed moves during the examination, and therefore, there are other potential safety hazards such as pipe clamping due to the fact that the pipeline cannot be properly fixed.

In view of the above, how to fix the high-pressure contrast injector pipeline system properly is a problem to be solved.
