Device

Last updated: 24 Sep 2025

Introduction #

The Device model represents a type of a manufactured item that is used in the provision of healthcare without being substantially changed through that activity. The device may be a medical or non-medical device.

Basic usage #

To get a device by identifier, use the get method on the Device model manager:

from canvas_sdk.v1.data.device import Device

device = Device.objects.get(id="b80b1cdc-2e6a-4aca-90cc-ebc02e683f35")

If you have a patient object, the devices for a patient can be accessed with the devices attribute on a Patient object:

from canvas_sdk.v1.data.patient import Patient

patient = Patient.objects.get(id="1eed3ea2a8d546a1b681a2a45de1d790")
devices = patient.devices.all()

Filtering #

Devices can be filtered by any attribute that exists on the model.

Filtering for devices is done with the filter method on the Device model manager.

By attribute #

Specify an attribute with filter to filter by that attribute:

from canvas_sdk.v1.data.device import Device

devices = Device.objects.filter(manufacturer="ACME Biomedical", lot_number="M320")
