Description

HANDHELD ELECTRONIC DRUG-REQUESTING DEVICE FOR USE WITH PATIENT- CONTROLLED ANALGESIA TECHNICAL FIELD [0001] This application relates generally to control of infusion devices. BACKGROUND [0002] Patient-controlled analgesia (PCA) is a commonly-used method to relieve pain experienced by a patient that can be more convenient for both the clinician and the patient. The method typically involves using a syringe pump programmed to allow for delivery of a predefined amount (e.g., a dose) of analgesia when the patient desires it. Some implementations of PCA include a patient-controlled device (e.g., a PCA wand or a PCA requestor) for the patient to request delivery of the analgesia. SUMMARY [0003] There is a growing need for PCA implementations (e.g., including handheld electronic drug-requesting devices) that provide more efficient, intuitive, safe, and better overall treatment experiences to patients. The present disclosure discusses various implementations of devices, systems, and methods for providing patient interactions with drug-requesting devices (e.g., dose-requestors) to improve the patient care experience and/or reduce clinician work (e.g., by minimizing patient intervention). For example, some implementations include providing patients with information about their patient profile (e.g., timing of doses) and information that improves their use of the PCA system (e.g., minimizing and/or otherwise optimizing dose request times based on providing dose-timing information and/or data detected by sensors of the drugrequesting devices to the patient), including feedback to improve drug delivery (e.g., by optimizing dose levels) and to minimize drug diversion and/or mechanical failures (e.g., based on a patient sitting on a tube of a fluid infusion pump). A handheld drug-requesting device according to various implementations described herein can allow for bi-directional patient interactions to obtain feedback about an amount of pain that the user is in while at a same time receive input to cause delivery of a dose of a drug (e.g., an analgesic). For example, the bi-directionality of the feedback provided between the patient and a patient care device that is facilitating PCA delivery and/or delivery of other types of drugs can provide for improved functionality of the device (e.g., by minimizing and/or preventing drug delivery processes that are not safe, authorized, and/or otherwise appropriate). For example, feedback provided by the dose requester to the patient (e.g., when a dose will be available to be delivered) may prevent the amount of drug requests submitted by the patient, thereby reducing computation performed and/or power consumption, since the patient is more informed about when drug delivery is available. [0004] The handheld electronic drug-requesting further improves patient care feedback mechanisms by facilitating pain feedback after a dose of a drug has been delivered to the patient. In some implementations, patient feedback and/or other patient interactions with the handheld electronic drug-requesting devices (e.g., involuntary movements) can be provided to an artificial intelligence model (e.g., a machine-learning model stored at a server) to improve detections of issues related to the drug delivery. Allowing the patient to provide such inputs directly to the drugrequesting device also allows for a more seamless overall treatment experience by not requiring a clinician to manually assess and/or request information about levels of pain that a patient is experiencing. [0005] In addition to the improved functional capabilities described above, it is understood that structural aspects of the handheld electronic drug-requesting devices herein, either alone or in conjunction with the improved functional capabilities, contribute to an improved patient experience. For example, the patient can easily request drug boluses while performing other related operations and providing feedback with the handheld electronic drug-requesting device using one hand, and in some cases, as little as a single touch input (e.g., via a patient’s thumb can cause performance of any of the operations described herein). Other technical improvements of implementations described herein will be made apparent to one of skill in the art based on the discussion provided herein. [0006] According to various aspects, a handheld electronic drug-requesting device is provided. The handheld electronic drug-requesting device includes a handle configured to be grasped by a hand of a patient; a display integrated in the handle; a touch-activated control integrated in the handle or the display; one or more processors; and a memory comprising instructions stored thereon that, when executed by the one or more processors, cause operations comprising: determining the handheld electronic drug-requesting device is electronically coupled to a drug-delivery device for delivery of a drug to the patient; receiving, in response to determining the hand
