Description

Medical instrument cleaning machine

Technical Field

The invention relates to the technical field of medical instrument cleaning, in particular to a medical instrument cleaning machine.

Background

In the medical field, and particularly in the field of infusing fluid to a patient or aspirating fluid from a patient, there is a need to prevent the transmission of pathogens from potentially contaminated surfaces, or "stains," of medical implements into or onto the patient. Such pathogens include microorganisms, such as bacteria and viruses. The transmission of pathogens into patients can lead to infections, which can be life threatening. In particular to the context of medical hygiene, the term "nosocomial infections" describes those infections that originate from or occur in a hospital or hospital-like environment. In the united states, nosocomial infections are estimated to occur in at least 5% of acute care hospitalizations. The estimated incidence is over two million cases per year, with an additional cost of over 45 billion dollars. It is estimated that nosocomial infections increase the mortality and morbidity risk of any inpatient more than two-fold, likely resulting in approximately 90000 deaths annually in the united states. Common stains of such transmission are found on such medical devices as luer ports, vials, needleless valves, or injection ports for vessels, tubes, or catheters. Even non-invasive medical instruments such as stethoscopes can transmit pathogens to patients. The incidence of infections in patients is currently numerous and increasing, and Infection Control Physicians (ICP) often list inappropriate cleaning of stains as a major source of these infections.

The medical equipment cleaning machine is a popular term, the medical equipment cleaning equipment used in the hospital is mainly divided into 2 types, one type is a medical full-automatic cleaning machine, the other type is a medical ultrasonic cleaning machine, the two types are used respectively, the medical full-automatic cleaning machine sprays foam by high-pressure jet flow, and is widely disinfected, rinsed and dried by 90-degree hot water, and the medical full-automatic cleaning machine is a main device for replacing manpower in the hospital at present. However, the general medical equipment cleaning machines on the market only simply wash the equipment with water, so that the purpose and the requirement of cleaning cannot be met, residues still exist on the surface of the equipment, the cleaning is not thorough enough, and the cross infection of patients is easily caused.
