การพัฒนาต้นแบบอุปกรณ์รักษาอุณหภูมิสำหรับยาแช่เย็น

Abstract

This research aims to study the specification design and the development of a temperature control pack prototype for refrigerated medicine by applying Quality Function Deployment (QFD) technique. The samples include pharmacists or related medical staff, outside patients, and patients’ relatives or representatives. The research method uses an interview to query pharmacists about the sample's basic needs, then gathers and combines to design questionnaire on the level of importance for each factor and design questionnaire on the satisfaction level of the current method for refrigerated medicine distribution services. Sample groups weight calculations have applied the use of the Analytic Hierarchy Process (AHP) technique to calculate the average level of demands, and the Planning Matrix or House of Quality (HOQ) to determine the process to meet samples’ requirements. Start with analyzing technical descriptors, followed by the relation between technical descriptors and user’s requirements to set a target for device development, and the relation on each factor of technical descriptors. This component can create a specification design of a temperature control pack prototype for refrigerated medicine which meets users’ requirements. The specification can conclude the design concept for developing a device from an experiment, selection of materials, and raw materials that are suitable in terms of safety, performance, and cost. The result of the development can create a temperature control pack prototype for refrigerated medicine which can maintain the temperature for 4 hours and have a manufacturing cost of 38.28 Baht/set. The prototype consists of thermal insulation packaging, a self-cooling gel pack, and a temperature indicator. The developed device also has a higher satisfaction level than an old device which currently used for service by pharmacists, indicating that this new device can satisfy the higher needs of the user.
