What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests whether a new device called Blood'up can help locate the radial artery in the wrist better than the traditional method of feeling for the pulse. Healthy volunteers will have arterial blood samples taken from both wrists, one using the device and the other using manual palpation, to compare success rates. The study also includes a group where low blood pressure is simulated with a blood pressure cuff, to see if the device helps when the pulse is harder to feel. The goal is to see if this technology could reduce the number of needle sticks needed and improve patient comfort.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Blood'up device (a non-invasive ultrasound-based device that projects a light signal to locate the radial artery) compared with manual palpation
What this could lead to
If effective, this device could help healthcare workers find arteries more easily, especially in patients with low blood pressure, reducing pain and complications from repeated punctures.
What could go wrong
This is a small pilot study in healthy volunteers, so results may not apply to real patients. The device is still under development and may not improve success rates as hoped.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 32 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start

Sep 2026

An estimate. Start dates often move.

Expected to finish

Sep 2027

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 years and older

Sex

Anyone

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Participant who has agreed to take part in the study * No history of cardiovascular disease and a positive Allen test (the Allen test confirms the presence of collateral circulation between the radial and ulnar arteries) * Age ≥ 18 years * Body mass index (BMI) \< 30 kg/m² Exclusion Criteria: * Raynaud's syndrome/disease * Damaged or injured skin at the puncture site or at the Blood'Up device contact area * Upper limb amputation * Contraindication to arterial puncture in one or both upper limbs (e.g., skin lesion, lymph node dissection, etc.) * Contraindication to extrinsic arterial compression * Therapeutic anticoagulation * Known allergy to thermoplastic (ABS) * Known allergy to EMLA patch (lidocaine or prilocaine) * Pregnant or breastfeeding women
