Leading Speech: With the continuous development of science and technology and economy, medical devices play an increasingly important role in modern diagnostic and therapeutic activities, maximizing the level of diagnosis and treatment of a hospital. The advanced technology is continuously applied to medical devices, which makes the degree of automation and complexity of medical devices higher and higher. This places higher requirements on the maintenance and management of medical devices in hospitals, and medical device maintenance management has become increasingly The more important it is. At present, medical device maintenance management has become an important part of hospital quality assessment.
Reporter: As medical devices play an increasingly important role in modern diagnostic and therapeutic activities, the phenomenon of “re-medical care” has gradually changed. But another phenomenon can not be ignored, that is, the "reuse of light management" of medical devices, highlighting the maintenance management. At present, what are the main problems in hospital medical device maintenance management?
Li Haoyue: Indeed it is. Although most hospitals currently have a relatively complete management system for medical devices, medical device maintenance is a blind spot for management, and medical device maintenance and management is relatively weak. Outstanding performance in three aspects: First, the maintenance of technical means behind. It should be said that the medical equipment repair status in our country is very similar to that of the United States in the 1970s. It belongs to the nature of a "maintenance shop." Although medical equipment maintenance conditions have improved in some hospitals with the continuous development of medical devices, this improvement is far from the maintenance requirements of modern medical devices. Maintenance tools and detection methods are still old.
Second, the maintenance management system lags behind. The standardized maintenance management of medical devices plays an important role in improving the integrity of medical devices. Without a standardized maintenance management organization and method, it is difficult to do a good job in the maintenance of medical devices, not to mention the effective acquisition of human physiological parameters related to clinical diagnosis and treatment, and to study the structure and physiology of the human body from the aspects of engineering biology and basic medicine. However, at present, the maintenance management system of most hospitals is incompatible with the requirements of modern medical device maintenance management, and lacks a standardized management system. Even hospitals that have established medical device maintenance management systems cannot easily revise and supplement related systems.
The third is the lack of regular maintenance management. The daily inspection and periodic inspection of medical devices is a regular maintenance work and the basis for equipment maintenance. It is a preventive work to check the accuracy, performance, and state of the equipment. It is to reduce equipment losses, eliminate hidden troubles, and maintain normal work. Extend the useful life of the preventive measures. In reality, many hospitals, especially small and medium-sized hospitals, cannot obtain effective maintenance and regular maintenance for their commonly used medical devices, which greatly reduces the service life and efficiency of the devices, thereby increasing the medical costs of the medical units.
Reporter: What are the reasons for the above problems?
Li Yumin: To explain the reasons, the most fundamental point is that hospitals themselves are reluctant to invest more in the equipment (facilities) necessary for maintenance, because the return on this investment is not obvious, and it is difficult to have immediate economic benefits. In addition, because of capacity problems, the hospital's planning and development strategy lacks clear construction and management standards for medical device maintenance organizations. It is difficult to accurately grasp the development and management strategies and quality requirements of medical devices, and it is difficult to timely formulate or modify related Management System.
At the same time, heavy medical work has also led caregivers to neglect the management of medical devices for a long time. Because the proportion of the number of patients and nursing staff is extremely unbalanced, the nursing staff often care only about the heavy nursing work, without taking care of others. Even if some deficiencies in the management of equipment were discovered during the work process, they could not be promptly corrected for fear of influencing the more important work. When shifts were made, they forgot the succession of nurses, which led to problems that could not be solved in time.
Reporter: In the face of this situation, from which aspects should hospitals improve the level of medical device maintenance and management?
Li Haoyue: I think the hospital should start with the two most fundamental aspects: First, to strengthen the inspection and maintenance of medical devices. This inspection is divided into two types, one is daily inspection. The daily inspection of medical devices is a regular maintenance work and the basis of equipment maintenance, which can prevent malfunctions and accidents. This work is generally performed by users. Careful daily maintenance is essential to ensure the normal operation of instruments and equipment. Routine maintenance should mainly be done: keep the surface of the instrument clean; check whether the voltage, power supply or voltage regulator is normal before use; check whether the corresponding circuit, optical path and waterway are normal and unobstructed; if the waterway is not smooth, rinse it in time; Observe that the function and performance of the instrument are normal and fill in the use records in time; after the instrument is shut down, the dust cover should be promptly closed; when the instrument and equipment fail, besides making the necessary records, the maintenance personnel should be promptly notified and must not be disassembled privately. . The other is regular inspections. Regular inspections are periodic preventive maintenance of medical devices. The purpose is to check the accuracy, performance, condition and pre-repair inspection of the equipment. This is usually done by maintenance personnel. In order to ensure the normal use of instruments and equipment, according to the performance requirements of the instrument and equipment, regular meticulous maintenance, such as regular dust and cleaning instruments and equipment, and performance testing; regular lubrication of operating parts, timely inspection and replacement of wearing parts Check the stability and grounding conditions of large or precision medical equipment.
The second is to develop a medical device maintenance management system. These include the establishment of an access system for medical device maintenance personnel, the introduction of a reasonable competition mechanism, and the full mobilization of the enthusiasm of maintenance personnel; the improvement of the maintenance system, the division of labor for maintenance personnel, the clear responsibility, and the need for specialized maintenance personnel for large-scale equipment Maintenance. At the same time, the management system should be divided into maintenance organization organization management system, leadership responsibility system, maintenance personnel responsibility rules, maintenance facility management system, accident liability rules, maintenance equipment file management system, retirement compensation system, personnel assessment and training system, and maintenance funding guarantees. Management system, etc. In particular, it is necessary to strengthen the leadership and management of hospital maintenance organizations, give full play to the role of engineering and technical personnel, improve maintenance quality, and reduce maintenance costs. The job responsibilities of the supervisory leader shall include: Organizing the establishment or supervising the implementation of the medical device maintenance management system, organizing the review of the maintenance organization's work plan, supervising the implementation, and approving the maintenance agency's expenditure plan. The engineering and technical personnel should do a reasonable division of labor and strict management so that they can continuously improve the quality and speed of maintenance, thereby maximizing the service life of medical devices.
Li Yumin: To add that, in addition to the implementation of standardized inspection and maintenance management, we must also explore scientific modern management methods. The maintenance of medical devices is a very complicated task. It is not enough to have practical experience and mental memory. While mastering maintenance techniques, it is also necessary to set up technical files with the aid of technical records of medical devices. This is for large-scale precision instruments. If necessary, it must have certain written records for other instruments and equipment, otherwise it will bring great difficulties to the maintenance work. Therefore, hospitals need to gradually establish a state library of medical devices, which has important reference value for equipment fault diagnosis. At the same time, we must establish an information feedback system, the core is to collect and sort out the existing data and classify and archive, such as: the use of testing equipment, repair tools; storage of spare parts, the use of funds; maintenance records; failure analysis; maintenance plan; maintenance information, etc. . Conditional units can establish medical equipment maintenance management computer systems, and organize computer networking to expand information capacity to meet the needs of maintenance management. Generally speaking, the supply of medical equipment parts is difficult to solve. This is related to the continuous updating of equipment and parts. It is difficult to rely on the supply of manufacturers and maintenance costs of repair stations are relatively expensive. Therefore, it is necessary to realize the socialization of spare parts for medical equipment maintenance.
