Outreach Clinic Checklist for Portable Ultrasound
An outreach clinic and an outpatient room are two different things.
In the outpatient room there is mains power, a network and a fixed space, so the equipment can be set up however suits the workflow. Out in a village there may be none of these, and there are still as many people to see as possible in the time available. The criteria for choosing equipment are therefore quite different.
This article works from the three hard constraints of an outreach setting and sets out a checklist for choosing portable ultrasound.
1. The three hard constraints first
1. Uncertain power. A village clinic or a temporary site does not necessarily have a working socket, and even where there is one it may be in use. A power bank or a vehicle supply is often the more realistic answer.
2. Uncertain network. In a village even the mobile signal can be patchy, let alone Wi-Fi. Any device that depends on an external network will run into trouble here.
3. Tight time and staffing. Several dozen to over a hundred people in a day means the equipment has to be quick to pick up, quick to switch between examinations, and free of repeated setup.
These three constraints drive the checklist below.
2. The checklist: six points
1. Portability: can one person carry it, does it fit in one bag
Conventional portable ultrasound is "portable" but still means carrying a main unit. A wireless probe puts the main unit inside the probe, so going out means one probe plus a phone or tablet.
Size and weight decide directly how many units you can bring, how far you can walk, and whether one person can manage the load.
The rule: configure for "one person can carry it all", not for "two people can lift it".
2. Power: does it last a day, can it charge while in use
Scanning continuously at a normal working pace, the device runs for about 3 hours; a full charge takes about 2-3 hours.
Charging can be through a USB cable, or with a wireless charging pad or power bank. With wireless charging the probe simply goes back on the pad between examinations, so the work does not have to stop while it tops up.
The rule: prepare at least two power arrangements (built-in battery plus power bank) and rotate them, rather than waiting for the battery to run out and then looking for a socket.
3. Network: it must not depend on the venue's Wi-Fi
This matters most in the field, in a village clinic or at a temporary site.
The device sends images over the Wi-Fi signal generated by the probe itself, so no Wi-Fi is required at the venue. Images reach the phone or tablet even where there is no network at all.
"What do we do in the field with no Wi-Fi?" is one of the first questions customers ask, and this is the answer.
4. One device, several examinations: can one probe cover more than one site
The people attending an outreach clinic need very different examinations: abdomen for some, thyroid for others, gynaecological examination for others. Bringing several systems is not realistic, so one device covering several examination types matters most.
| Configuration | Composition | Covers |
|---|---|---|
| Dual-head probe | Convex + linear | Abdomen + superficial |
| Three-in-one probe | Convex + linear + cardiac | Abdomen + superficial + cardiac |
Models to look at: 5CP (dual-head, convex 3.2MHz-H5MHz / linear 10-12MHz) and 5CL (three-in-one, convex 3.2MHz-H5MHz / linear 7.5MHz-H10MHz / cardiac 3.2-5MHz).
The rule: where there are many people and a wide mix of conditions, a dual-head or three-in-one probe saves more effort than carrying two single-head probes.
5. Cleaning and protection
Examining one person after another means the probe has to be turned around quickly. Because the device is small and has no probe cable to get in the way, it can be covered entirely with a single-use sheath, which makes handling quick when several people are seen in succession.
Coupling gel has to be stocked for the expected number of patients - this is the item most often underestimated.
6. Display and records
Images are displayed on a phone or tablet, so there is no separate screen to carry. Images can be stored and exported, which makes it easy to keep a record on site, to review afterwards, or to ask a clinician at a higher-level hospital for a reading.
3. A checklist you can pack from
| Group | Item | Suggestion |
|---|---|---|
| Equipment | Probe | Dual-head or three-in-one, covering abdomen and superficial |
| Equipment | Display device | Phone or tablet; a spare is advisable |
| Power | Supply | Built-in battery plus power bank or wireless charging pad |
| Power | Cables | USB charging cable |
| Consumables | Coupling gel | Enough for the expected number of patients |
| Consumables | Sheaths | Single-use probe sheaths |
| Consumables | Interventional accessories | Single-use needle guide if guided procedures are planned |
| Other | Cleaning supplies | Probe cleaning and disinfection supplies |
| Other | Records | Examination record sheets, so that follow-up and referral can be traced |
4. Three reminders for the day itself
1. Set the image up before starting. The light is awkward and time is short, and precisely because of that it is worth one minute on gain, depth and focus first. If the image is not readable, everything that follows is wasted.
2. Be clear about the limits. What an outreach clinic does is initial screening. When something abnormal is found, the advice should be further examination at a higher-level institution, not a conclusion on the spot. That is the right thing both for the patient and for the organising body.
3. Save the images as you go. It makes later review and follow-up easier, and allows a senior clinician to be asked for a reading.
5. Common questions
Q: What if the power runs out on site?
A: Connect a power bank, or top up on a wireless charging pad. With wireless charging, the probe goes on the pad between examinations and the work does not have to stop.
Q: Can it be used in a village with no network?
A: Yes. The device uses the Wi-Fi signal generated by the probe itself, so no Wi-Fi at the venue is required.
Q: Can it connect to a laptop?
A: Laptops are generally Windows machines, and a Windows version of the software is available, so a laptop can be used.
Q: Can one person examine several patients at the same time?
A: A probe connects to one phone or tablet at a time. On Android devices, Wi-Fi Direct can be set up to mirror the display to more than one screen.
6. Selection guidance
If the outreach work is mainly abdomen plus superficial, a dual-head configuration usually covers it; if cardiac examination is also needed, consider the three-in-one configuration.
The exact model depends on which examinations are done, how many patients are expected and the budget.
The above is the general version. The Outreach Clinic Equipment Checklist and the full Ultrasound Probe Selection Table set out probe configurations and parameters for each model; ask our product team for a copy.
Summary
- Three hard constraints on outreach work: power, network, time
- Configure portability for "one person can carry it all"
- Runtime is about 3 hours - always prepare a second power arrangement
- Choose a device that does not depend on the venue's Wi-Fi; it then works in the field and in a village clinic alike
- For a wide mix of conditions, a dual-head or three-in-one probe saves both effort and money
- What happens on site is initial screening; anything abnormal should be referred for further examination
