A handheld precision liquid dosing device with single-use oral solution pods, designed around a clinician’s plan.
Explore the proposed design below. Bonsai is pre-production, not available to buy or preorder.
The proposed design
Explore the display, controls, pod, and charging port. These are proposed features, not working hardware.
Select a number to read about that feature. Every explanation is also available below its view.
The display is intended to show the planned amount and device status. These screen studies illustrate individual prompts, not a live session.
The completion symbol does not confirm delivery or bodily intake.
Planned amount
Not shown in these screen examples.
Would show the clinician’s planned amount alongside device status. The screen examples illustrate the design, not live readings.
Would indicate a connection between Bonsai and the patient app. Hardware connectivity is in development; connections in the demo are simulated.
Would show the clinician-set amount for a session. This is a planned amount, not a measurement of what a person consumed.
Would show the battery’s charge level. Battery life and charging performance are unannounced.
Would estimate how much remains in the pod based on device activity. It would not be an exact contents measurement or a measure of bodily intake.
Three proposed buttons would let the patient start a session and adjust its planned amount within clinician-set limits. Final button layout and behavior are unconfirmed.
Physical controls
Choose a button to read about its intended purpose.
Would increase the planned session amount only within the clinician’s limits, not allow independent treatment changes. Button behavior and the amount changed by each press are not yet defined.
Would decrease the planned session amount within the clinician’s limits. Button behavior and the amount changed by each press are not yet defined.
Plan boundary
The clinician sets the limits. The buttons would not let patients set their own treatment dose.
A single-use pod would hold the oral solution. An internal reader would link the pod to product information, not verify its physical contents.
Inside the device
The reader is not pictured.
Would link a pod to product, batch, and available lab records. Physical pod reading is in development; a linked record cannot verify the pod’s physical contents.
A proposed single-use pod for an oral solution. Pod capacity and product compatibility have not been announced.
The concept places a charging port at the base. Its appearance does not confirm charging speed or a connector standard.
A proposed charging port at the base. The USB-C-shaped design does not confirm a connector standard or charging speed.
Connection
Hardware connectivity is in development. The software demo uses simulated connections; records reach the care team after upload, not as a continuous live feed.
The patient would start a session on the device within the clinician’s plan. Bonsai would record device activity, not measure bodily intake.
Patients can see the plan, follow a simulated session, add feedback, and check whether records have uploaded.
The patient’s linked care team can set the plan and review uploaded records alongside patient feedback.
The software demos use fictional example data, not a live device. Recorded activity does not prove intake or benefit, and an uploaded record has not necessarily been reviewed.
External research · not Bonsai results
Evidence boundaryExternal research describes different problems and populations, not Bonsai study results. Bonsai is pre-production; improved dosing accuracy, adherence, and outcomes have not been established.
40%
12 of 30 oral cannabis oils were outside the ±15% THC label tolerance.
Products sampled from the Ontario Cannabis Store, November 2021–January 2022.
Small, nonrepresentative sample—not all cannabis. This measured label accuracy, not delivered dose. Labels mostly overstated contents; this is not evidence of widespread excess THC.
Current status
The patient app and Care Portal demonstrate the software workflow with fictional example data. Physical device operation is not part of the demo.
No clinical benefit, safety validation, certification, or regulatory approval is established.
The device, controls, and charging port remain concepts. Hardware Bluetooth connectivity and physical pod reading are in development; the demo simulates them.
