Abstract

The invention provides a medicine expiration date identification system based on color change, which comprises a storage basket body, an expiration date setting module and a central control module, wherein the medicine expiration date state is marked through the color change of the storage basket body, and a user does not need to check medicine packaging labels one by one manually, so that the user can identify which medicine expiration dates are safe and which are about to expire and which are expired at a glance, the efficiency of checking and managing the expiration date is greatly improved, the manual burden and the error rate are reduced, the central control module continuously calculates the residual duration and drives the color change, when the medicine enters an early warning period or a critical period from the expiration date sufficient state, the color of the basket body can be automatically and timely changed to form strong visual reminding, the medicine expiration and the use risk caused by negligence are effectively prevented, and electrochromic materials are directly applied to the storage basket body or a specific area thereof and integrated with the expiration date setting and the control module to form an independent intelligent management unit.

Claims (6)

1. A drug expiration date identification system based on color change, comprising: a storage basket made of a member including an electrochromic material, capable of changing its display color under the control of an applied electric field; The expiration date setting module is fixedly arranged on the storage basket body or is in communication connection with the storage basket body and is used for a user to input or select a preset expiration date time point of medicines stored in the storage basket body; The central control module is respectively and electrically connected with the expiration date setting module and the electrochromic member of the storage basket body, and a first early warning threshold value and a second early warning threshold value are preset in the central control module; The central control module calculates the residual time between the current time and the preset validity time point in real time or periodically, compares the residual time with the first early warning threshold value and the second early warning threshold value, controls the storage basket to display a first color when the residual time is larger than or equal to the first early warning threshold value, controls the storage basket to display a second color different from the first color when the residual time is smaller than the first early warning threshold value and larger than or equal to the second early warning threshold value, and controls the storage basket to display a third color different from both the first color and the second color when the residual time is smaller than the second early warning threshold value.
2. The color change-based drug expiration date identification system of claim 1, wherein a specific identification area is arranged on the storage basket body, the specific identification area is made of electrochromic materials, and the specific identification area is a frame, a label clamping groove or a bottom of the storage basket body.
3. The color change-based drug expiration date identification system of claim 1, wherein the expiration date setting module is a physical key combination.
4. The drug expiration date identification system based on color change according to claim 1, wherein the first pre-warning threshold is 6 months, the second pre-warning threshold is 3 months, the first color is blue, the second color is yellow, and the third color is red.
5. The drug expiration date identification system based on color change according to claim 1, further comprising a wireless communication module, wherein the wireless communication module is connected with the central control module and is used for sending the identity information of the storage basket, the preset expiration date time point and the current color state to a remote management server, and the central control module is further connected with an audible and visual alarm, and when the remaining duration is smaller than the second early warning threshold value, the audible and visual alarm is triggered to alarm.
6. The medicine validity period identification method based on the color change is characterized by comprising the following steps of: the method comprises the steps of inputting a preset expiration time point of a target medicine through an expiration setting module, obtaining current time by a central control module, calculating residual time between the current time and the preset expiration time point, comparing the residual time with a preset first early warning threshold value and a preset second early warning threshold value, generating a corresponding color control instruction according to a comparison result, and sending the corresponding color control instruction to an electrochromic component of a storage basket body, wherein the electrochromic component responds to the color control instruction to change the display color of the storage basket body.

Description

Drug expiration date identification system and method based on color change Technical Field The invention relates to the technical field of medicine management, in particular to a medicine validity period identification system and method based on color change. Background Drug expiration management is a critical and tedious task in medical institutions, pharmacies, nursing homes, and home settings. At present, common drug expiration date management mainly relies on manual checking of expiration date labels on drug packages, and checking and arrangement are performed regularly. The manual inspection is low in efficiency, and easy to cause missed inspection due to visual fatigue or negligence, especially when the quantity of medicines is numerous or the storage positions are scattered, the real-time dynamic monitoring of the effective period cannot be realized, the state change of the medicines from the effective period safety to the near failure cannot be intuitively and timely perceived, and the medicines are easy to expire unknowingly, so that the medicine waste or the safety risk of misusing the expired medicines is caused. Disclosure of Invention In view of this, the present invention proposes a drug expiration date identification system and method based on color change in order to solve the problems existing in the technical background. The method specifically comprises the following steps: a drug expiration date identification system based on color change, comprising: a storage basket made of a member including an electrochromic material, capable of changing its display color under the control of an applied electric field; The expiration date setting module is fixedly arranged on the storage basket body or is in communication connection with the storage basket body and is used for a user to input or select a preset expiration date time point of medicines stored in the storage basket body; The central control module is respectively and electrically connected with the expiration date setting module and the electrochromic member of the storage basket body, and a first early warning threshold value and a second early warning threshold value are preset in the central control module; The central control module calculates the residual time between the current time and the preset validity time point in real time or periodically, compares the residual time with the first early warning threshold value and the second early warning threshold value, controls the storage basket to display a first color when the residual time is larger than or equal to the first early warning threshold value, controls the storage basket to display a second color different from the first color when the residual time is smaller than the first early warning threshold value and larger than or equal to the second early warning threshold value, and controls the storage basket to display a third color different from both the first color and the second color when the residual time is smaller than the second early warning threshold value.
