Quick facts
- A nonpneumatic tourniquet is a named Class I device in the United States at 21 CFR 878.5900.
- Canada names no blood collection tourniquet. A strap applied over intact skin is a non-invasive device, and Rule 7(1) of the Medical Devices Regulations places it in Class I.
- The class is the same on both sides; the route is not — the United States sorts by named entry and product code, Canada by the contact it makes.
- A pneumatic tourniquet is a separate US entry at 21 CFR 878.5910, still Class I, but a different device.
- A tourniquet left on a patient is a clinical event, not a device class; the class does not change with a prolonged draw.
- The regulation text quoted here is current to 2026-09-21 and was last amended on 2026-06-17.
A blood collection tourniquet is a strap or band wrapped around the arm and tightened to make a vein easier to see before a needle is placed. It is one of the most common objects in a blood draw tray, and it is the object most often assumed to need no classification work at all. Both countries place it in Class I, but they reach that class by two different paths, and a supplier may have to cite the right one.
What is a blood collection tourniquet?
It is a band that is wrapped around a limb and constricted for a short time to slow venous return and fill the vein. A nonpneumatic tourniquet is a simple elastic strap or a roll of latex-free band; a pneumatic tourniquet uses a cuff and a pump to set a pressure.
The nonpneumatic version has no gauge, no pump and no power source. It is a mechanical strap that presses on the arm. It does not enter the body, it does not touch injured skin, and it does not deliver or withdraw energy. Those facts decide its class in Canada, and they are the reason a strap with no electronics still has a defined place in both rulebooks.
How do Canada and the United States classify a blood collection tourniquet?
The strap lands in Class I on both sides of the border, but through two different doors.
| Item | Canada | United States |
|---|---|---|
| Nonpneumatic tourniquet | Class I by Rule 7(1) | Class I, 21 CFR 878.5900 |
| Pneumatic tourniquet | Class I by Rule 12 if active | Class I, 21 CFR 878.5910 |
| Basis named in the rulebook | Rule and intended use | Device entry and product code (GAX) |
| What decides the class | Contact made and energy source | Which named entry it is filed under |
| Tourniquet kit | Class follows the highest component | Entry and accessory |
In the United States the nonpneumatic tourniquet is a named entry at 21 CFR 878.5900, and the pneumatic version is a separate entry at 21 CFR 878.5910. Both are Class I. In Canada no entry names a blood collection tourniquet. It is a non-invasive device that presses on intact skin, so Rule 7(1) places all other non-invasive devices in Class I. A pneumatic cuff that depends on a pump is an active device, but it does not treat or diagnose, so Rule 12 keeps any other active device in Class I as well.
Which documents differ between Canada and the United States for a tourniquet?
The class is identical, which is exactly why the paperwork trap is easy to miss.
In the United States the named Class I entry carries the design and labelling controls that entry sets out, and a supplier works from the entry number and product code. In Canada the strap is a Class I medical device under Rule 7(1), subject to the establishment and record requirements the Regulations set for that class, with the labelling rules applied. The difference is not the class number; it is the reference a supplier cites when a laboratory buyer or an inspector asks why the device is Class I at all.
That is why two tourniquets that look the same can arrive with two different file references. One file cites a US entry and a product code; the other cites a rule and an intended use. A supplier selling into both markets has to hold both, because a reference that is correct in one country is not accepted in the other.
Why does a strap over intact skin stay Class I in Canada?
Because the rulebook asks what the device touches, then where its energy comes from, and stops if neither answer raises the class.
The strap does not penetrate the body and does not touch the surface of the eye, so the invasive rules do not reach it. It is intended to contact intact skin, not injured skin, so Rule 4 does not apply. It does not channel or store gases or fluids into the body, so Rule 5 does not apply. It does not modify the composition of blood for reintroduction into the body, so Rule 6 does not apply. It is a non-invasive device that is not a calibrator and not connected to an active device in a higher class, so Rule 7(1) classifies it as Class I.
The one distinction a supplier has to keep straight is the difference between a strap and a cuff. A pneumatic tourniquet adds a pump and a gauge, which makes it an active device, but Rule 12 still classes any other active device as Class I because the cuff does not administer or withdraw energy to or from the body for treatment. The class stays put; only the route changes.
There is one more line a blood collection service should keep in view. A device that is intended to contact injured skin reaches Class II under Rule 4(1), and only a device used as a mechanical barrier, for compression or for the absorption of exudations stays in Class I under Rule 4(2). A strap used over intact skin on a healthy arm does not engage that rule at all, which is why the base non-invasive rule applies. The rule only becomes relevant when the device is intended for broken skin, such as a dressing or a compression bandage, and that is a different product with a different class.
Which consumables does a blood collection tray restock?
A draw station runs on a short list of items that are used on every patient. The sterile graduated 90 mL specimen cups and the 120 mL sterile screw-cap container carry collected samples away from the bench, and the double-tipped cotton swabs handle site preparation. Where a laboratory also monitors its own steriliser, the sterilization monitoring collection pairs with the 24-hour monitoring five-pack trial. Laboratories and multi-site groups ordering at case level use the wholesale ordering page, and the B2B wholesale collection lists the lines held for institutional buyers. Reselling? become a distributor.
What do the two rulebooks actually say?
The two texts are short, and reading them side by side shows why a strap still needs a citation.
| Rule or entry | Verbatim wording | Effect on a blood collection tourniquet |
|---|---|---|
| Rule 7(1), Canada | all other non-invasive devices are classified as Class I | The strap presses on intact skin, so Class I |
| Rule 4(1), Canada | intended to come into contact with injured skin | Does not apply, because the skin is intact |
| Rule 12, Canada | any other active device is classified as Class I | Keeps a pneumatic cuff in Class I |
| 21 CFR 878.5900, US | Tourniquet, nonpneumatic | Named Class I entry |
| 21 CFR 878.5910, US | Tourniquet, pneumatic | Separate named Class I entry |
Read together, the lines give a supplier a simple check. Name what the device touches, then name where its energy comes from, then name what it is connected to. A strap that presses on intact skin and does nothing else stays where Rule 7(1) puts it, and the US entry is a different way of saying the same thing.

A draw that is not logged cannot be reviewed when a sample is rejected. The printable blood collection log is a blank sheet with columns for the patient, the time, the tourniquet type, the site and the tubes drawn, so a repeat draw follows a written record. The collection record generator on the same page sizes the sheet to the number of chairs a laboratory runs. No account and no sign-up are needed to open either one.
Every laboratory layout is different. Ask a compliance specialist and you will get a written answer specific to your equipment and province, with the regulation or standard it is based on cited.

Frequently Asked Questions
Is a blood collection tourniquet a Class I device in the United States?
Yes. A nonpneumatic tourniquet is a named Class I entry at 21 CFR 878.5900, filed under product code GAX. A pneumatic tourniquet is a separate Class I entry at 21 CFR 878.5910.
How does Canada classify the same strap?
Canada names no blood collection tourniquet. It is a non-invasive device that presses on intact skin, so Rule 7(1) places all other non-invasive devices in Class I.
Does a pneumatic tourniquet change the class in Canada?
No. A pump and gauge make the cuff an active device, but it does not administer or withdraw energy to or from the body for treatment, so Rule 12 keeps any other active device in Class I.
Why does the class not change with a long draw?
The class follows the intended use and the contact the device makes, not how long a clinician leaves it on. A prolonged draw is a clinical event and is handled by procedure, not by reclassifying the strap.
What does the class change for a supplier?
The class is the same, but the reference is not. A US supplier cites a named entry and product code; a Canadian file cites a rule and an intended use, and the establishment and record requirements for a Class I device apply.
Does a tourniquet kit follow the strap?
A kit that adds another device takes the class of its highest-class component. A plain strap kit stays Class I in both countries, but a kit with a higher-class item does not.
