Description

Technical Field

[0001] The invention belongs to the technical field of medical supplies, and in particular relates to a cleaning agent kit for bedside pretreatment of flexible endoscopes. Background Art

[0002] As people's living standards improve, more and more people begin to pay attention to their health, and the use of medical devices is increasing. The safe use of medical devices has always been a focus of attention, especially the safe use of reusable medical devices, which has become the focus of attention of the whole society.

[0003] As a special medical device, endoscope plays an irreplaceable role in medical health. In recent years, endoscopes have been used more and more in minimally invasive procedures, physical examinations, and treatments. Whether the method of endoscope reprocessing is in compliance with the standards, whether the process is correct, and whether the selected cleaning consumables are appropriate all have an impact on the endoscope reprocessing results.

[0004] As the first step in endoscope reprocessing, bedside pretreatment of endoscopes directly impacts the subsequent cleaning and disinfection of endoscopes. Therefore, bedside pretreatment plays a crucial role in the endoscope reprocessing process. Selecting the appropriate bedside pretreatment cleaning agent or kit has long been a focus of hospitals and a key area of research for researchers in this field.

[0005] Bedside pretreatment agent is a special cleaning agent or cleaning kit that has the function of dissolving and decomposing proteins, fats, sugars, tissue fragments, blood stains, excrement, etc., while also softening and preventing dirt from drying out. It also has the function of moisturizing and maintaining the endoscope, thereby extending the service life of the endoscope.

[0006] Currently, the cleaning agents and wiping consumables used for bedside pretreatment are non-professional consumables, often consisting of water or alkaline detergents and gauze. Water only serves to moisten and flush, but its decontamination effectiveness is poor, making it difficult to remove organic matter such as body fat. While alkaline detergents are effective at removing tissue, protein, and blood stains, their strong alkalinity can cause endoscope material degradation, shortening the lifespan of endoscopes. Gauze, a common hospital consumable, plays an important role in various areas. While it can be used for wiping, it lacks the thoroughness of professional wipes. This method not only complicates pretreatment but, more importantly, makes it difficult to ensure effective treatment. Some of the substandard endoscope reprocessing in hospitals is related to bedside pretreatment. Summary of the Invention

[0007] To address the shortcomings of existing technologies, the present invention provides a cleaning agent kit for bedside pretreatment of flexible endoscopes. The cleaning agent features multiple enzymes, low foaming, antibacterial properties, and moisturizing properties. The specially formulated scrubbing pads perfectly conform to the endoscope structure, ensuring a more consistent cleaning experience. This makes bedside pretreatment of endoscopes more standardized and reliable.

[0008] The cleaning agent kit for bedside pretreatment of flexible endoscopes of the present invention is composed of a cleaning agent and a scrubbing cotton combination, wherein the cleaning agent is prepared from the following components in parts by mass:
