As medical sciences have progressed and new medicines discovered, the use of more precise and optimal methods of injecting medicinal fluids and more specifically injection in longer time spans has become evident. Peristaltic pump is used in almost all medical supervisions which require precision application of medicines more common in hospitals, elderly housings, clinics and private home patient care taking. This pump may be used for slow liquid medicine injections for the purpose of pain reduction in a wide spectrum of inpatient treatments as well as for tube feeding inpatients incapable of eating solid foods.
Due to the vital importance of peristaltic pump application precision medical institutions and in respect to previous design efforts done on this machine, the objective of this project is designing multipurpose model of it and preparing necessary plans for its industrial manufacturing using interaction design. In order to obtain the hospital nurses opinions as target population about the application and desired characteristics of a peristaltic pump, a survey research method (questionnaire, personal interview and observation) are applied. Finally, proposed plan for a novel product consists of a pump body taking into consideration the User Interface; ergonomics as well as aesthetics aspects are represented.
In this project we are willing to create and execute design solutions towards problems of user-Interface, form, usability and physical ergonomics. Whereby the aesthetics, ergonomics and usability of product will be improved for marketability and production.
The current consumers include the following groups:
Private Hospitals
Project focus ■ Public Hospitals
Personal Use
■ Develop a product and system that specifically support users ’activities, needs, and wants in unique and exciting ways.
■ Implementing a simple UI and short learning, To encourage widespread use for all users.
■ Improving accessibility to encompass the wide variety of the users ’disabilities.
■ Utilizing emerging technologies, materials, and processes.
■ Expanding the product into new areas of the market.
■ For patients with physical limitations, infusion pumps can be difficult to operate correctly.
■ With current infusion pumps, there is not appropriate feedback to the input controls of the unit. This allows erroneous entries without any warning.
■ Disabilities increase the risk of patient error in device operation.
■ At least one patient from our client list suffers from some form of a vision problem, a hearing impairment or an ailment that restricts motor function.
■ Carpal tunnel syndrome
■ Parkinson’s disease
■ Arthritis
■ Partial paralysis.
In order to meet project objectives, we will employ a “user-centered” development approach. This strategy focuses on the behavioral patterns and needs of potential users, rather than a more conventional product-centered development method which focuses on merely revamping existing designs.
By focusing exceptional amount of energy on user values and needs, I aimed to understand this topic sufficiently enough to drive the resulting concepts in the next phase. With such a thorough investigation into the user, I required the use of an analytical framework for research findings. The diagram at the bottom left shows my research framework, which indicates relationships between users and their context.
By collecting heavy amounts of data, true knowledge is not necessarily achieved. By using organizational frameworks and categorization, one can more quickly understand the subject researched; therefore, organizational methods was used to quickly progress from data to information (eventually creating knowledge and wisdom). The two forms shown below are examples of such tools, and were used during all user observation testing periods.
In this project I am considering what is valuable (to the user and society), possible (technologically and for the client) and what is desirable (in the marketplace). To understand these varying factors, I created an organized and comprehensive research approach, with four key topics. These topics are potential users, the client and its market, emerging technologies, and relevant socio-cultural trends. The diagram shows topic relationships, with the orange center suggesting the ideal synthesis of the collected information.
A survey research to determine groups of users of peristaltic infusion pumps was conducted mainly in central part of USA. The field study was conducted using Analytical Hierarchy Process (AHP) method and users most involved with applying and having interaction with peristaltic infusion pumps were determined to be nurses (80%), repair personnel (15%) and patients (5%). In this research in order to identify the target group and understand its perceptions for formulating design criteria a structured questioner, personal interview and observation techniques were used. Data was collected from twenty users including nurses, repairmen and patients from hospitals and private clinics in Houston during the winter of 2018. Data analysis and processing was performed to determine the design criteria for the infusion pump body and User-interface.
A hospital, in the modern sense, is an institution for health care providing patient treatment by specialized staff and equipment, and often, but not always providing for inpatient care or longer-term patient stays. Hospitals are usually funded by the public sector, by health organizations (for profit or nonprofit), health insurance companies, including by direct charitable donations. Conversely, modern-day hospitals are largely staffed by professional physicians, surgeons, and nurses, whereas in history, this work was usually performed by the founding religious orders or by volunteers.
All major activities occurring in the hospitals were listed. Further categorization allowed for the creation of the more simplified network at the right.
