Design Points of Handheld Medical Devices

Design Points of Handheld Medical Devices – Medical Device Coatings – Cheersonic

Compared with general medical devices, handheld medical devices have a wide range of functions, such as meeting patient requirements, occupying less space, convenient maintenance, and easy portability. Due to the widespread application of hand-held medical devices and great help to medical personnel and patients, many hand-held medical devices have begun to expand into new fields, and a series of products have been derived.

In the application of the actual medical industry, these products have not been well received as always, but have caused discussions in the society and debates in the academic circle. Overall use and subsequent development. The following is a brief analysis of the main points of hand-held medical device design, let’s take a look.

Safety

The market for hand-held medical devices is very broad. In order to further meet the needs of the majority of patients, in the process of designing hand-held medical devices, fixed requirements must be met, that is, the daily design points. At the same time, more design points must be achieved. A big breakthrough, otherwise it is difficult to meet the needs of real work. After long-term research, it was found that one of the design points of hand-held medical devices is safety.

First, when a hand-held medical device fails, it must be able to ensure the personal safety of the user instead of causing an accident.

Second, when hand-held medical devices are damaged during daily use, they should be displayed in prominent parts to inform patients that there is a problem with the medical device and prevent patients from continuing to use them.

Third, the daily contact part of hand-held medical devices is the user’s hand, so it is necessary to improve the protection measures for the hand to avoid wear and scratches.

Complexity

Modern medical devices integrate multidisciplinary research results, with complex functions and diverse modules. At the same time, the users of medical devices are also complicated. The users of hand-held medical devices are not all professional medical staff, and the user environment surrounding hand-held medical device products is not only medical staff. For example, in a home environment, users are mostly non-medical professionals, and may even be patients themselves. They do not have basic medical common sense and medical device operation knowledge.

The complexity of hand-held medical devices is the core part of hand-held medical devices. Its complex characteristics not only determine the performance of other characteristics, but also have a great impact on the practical application of this type of medical device. This study believes that the complexity of hand-held medical devices is not easy to grasp. In the future work, on the one hand, it is necessary to reduce the complex characteristics and improve other characteristics to help hand-held medical devices obtain more functions; on the other hand, it is necessary to grasp To avoid the impact of complexity, try not to affect the design and development of handheld medical devices.

Design

A key point that distinguishes hand-held medical devices from other medical devices is that the space occupied by this type of medical device is very small, and it is mainly operated by hand, and during the operation of smaller medical devices, the details of the operation are often determined. final result. Therefore, the design of the hand-held medical device is very important.

First, the shape of the hand-held medical device must be small, so that the operator can distinguish the function of this type of medical device in time. In terms of overall shape, it must have outstanding performance and can be found in time among many medical devices.

Second, the colors of hand-held medical devices should be clear, different colors represent different meanings, and the actual application situation should be considered. If the lighting is dim, the design of the hand-held medical device should be highlighted with bright colors; if the lighting is bright, use muted colors. The most important thing is that once encountering a special person with color blindness, the meaning expressed by color is very different. Therefore, in the grasp of color, a variety of situations must be considered.

Third, the design of the hand-held medical device should also be convenient for actual operation. Since this type of medical product is mainly used in the fields of delicate surgery and patient disability applications, the operational performance must reach a high level, and it must also have the characteristics of anti-pollution and anti-corrosion to ensure that it will not cause harm to patients and medical staff. harm.

Haptic Design

The haptic design of handheld medical devices is also a very important aspect. The tactile design mainly allows the operator to clearly feel that he is operating the medical device, and at the same time, it is more obvious in the feeling, so as to avoid unnecessary influence caused by excessive force or too small force.

Haptic design has always been an important aspect of hand-held medical device design, often serving as a design bottleneck. Membrane keys, for example, have become the dominant type of lightweight haptic controller. The functions on the membrane buttons of the pulse oximeter are not only the on/off control function used in the power supply, but also the conversion function for other on and off functions, and also have the step control function. Taking the pulse oximeter plus as an example, due to the influence of the structure and function of the pulse oximeter device itself, the design of the membrane keys should meet the operating procedures of one-handed holding, the control keys should be able to be operated with a single finger, and the arrangement of the control keys should not be easy to cause. Occurrence of misoperation. From the above statement, haptic design will directly affect the daily use, repair and optimization of handheld medical devices, and will have a greater impact on users.

In the future work, the haptic design must be more user-friendly. On the one hand, the sensitivity of the touch is improved, and on the other hand, the prohibition function of wrong operation is added. problems that occur are stopped. Conclusion This study analyzes the design points of hand-held medical devices. As far as the existing hand-held medical devices are concerned, they have largely met the needs of medical staff and patients. However, due to the increase in the number of patients and special cases The emergence of some handheld medical devices appears to be somewhat insufficient in performance, and needs to be further designed in the future.

Summarize

As we all know, the application fields of medical devices are very wide, and they have great positive significance for medical staff, disabled patients, and research work in the medical field, and can objectively change the status quo of medical work and the way of life of patients. It reaches a new level. Of course, there are many key points in the design of hand-held medical devices. In the design work, it is necessary not only to meet the specifications of the design points, but also to increase the value of hand-held medical devices and provide more help to medical staff and patients.

Ultrasonic nozzles are particularly suitable for a wide range of medical coating applications due to their very precise, non-blocking, repeatable spray performance and extremely low flow rate capability. For several years, Cheersonic has been providing ultrasonic medical coating system to medical device manufacturers worldwide. As medical device technology evolves, we will continue to design unique medical coating ultrasonic spray solutions to enhance patient safety and provide the highest quality medical device coating on the market.
