Contrast injector syringe assembly

Contrast injector syringe assemblies · CT, MRI and angiography power-injector syringes, injector compatibility, pressure rating against the injector limit, 125–200 mL volumes, connecting tubes and fill spikes, sterility and regulatory class

A contrast injector syringe assembly is the single-use, sterile syringe set loaded into a CT, MRI or angiography power injector: a barrel and plunger sized to the injector head, a connecting tube to the patient line, and a quick-fill tube or spike for drawing contrast media or saline. Ask three things first: which injector model it must fit, what pressure and flow it must withstand compared with the injector's limits, and what sterility, shelf life and registration the hospital or distributor requires.

Disposable syringe assemblies for contrast media power injectors used in CT, MRI and angiography (DSA), with their connecting and fill tubes. Power injectors themselves, hand syringes, prefilled contrast media, dispensing syringes for adhesives and general-purpose hypodermic syringes are outside this page.

01

Match the injector model and pressure limits

FDA 510(k) summary K042744 for the Mallinckrodt OptiVantage DH CT injection system lists syringes of all pre-filled volumes of 125 mL contrast syringes and a 200 mL front-loading empty syringe, a fill rate of 2–15 mL/s, a flow rate of 0.1–10 mL/s, a maximum pressure limit of 325 psi with user-settable or automatic limiting, a syringe heater, and an electromechanical drive in which a motor, gearbox and ball screw drive a ram attached to the syringe plunger. It is classified under 21 CFR 870.1650, angiographic injector and syringe, Class II, product code DXT, and states that syringes and disposables are provided sterile. [1]

The predicate CT9000ADV summary (K031339) likewise accepts 125 mL pre-filled syringes and a 200 mL syringe, and describes injections controlled by microprocessor for flow rate, volume and timing. [2]

Editorial calculation: a syringe rated 350 psi (2.4 MPa) leaves about 8% margin over a 325 psi injector pressure limit, and one rated 600 psi about 85%; ask the supplier for the burst and leak test pressure of the exact syringe and the injector models it is validated with. [1] [3] [4]

Give the supplier the injector make and model (CT, MRI, DSA; single or dual head), syringe volume, pressure rating needed, kit contents (connecting tube length, quick-fill tube or spike, T-connector), packaging and sterilisation, shelf life, registration needed in the target market (FDA, CE, NMPA), labelling language, OEM branding and quantities.

02

Check the kit contents, sterility and compliance

LnkMed lists a 200 mL CT syringe kit with one 200 mL syringe, a 1,500 mm coiled connecting tube and a quick-fill tube, a stated maximum pressure of 2.4 MPa (350 psi), EO sterilisation, single use, latex free, a 3-year shelf life, blister packaging at 50 per carton, and CE 0123 and ISO 13485 certification. [3]

WEGO lists a CT-200-LF high-pressure syringe for single use with DSA, CT and MRI injection equipment, a highest pressure limit of 600 psi, and connecting tube, quick-fill tube or spike accessories, and lists ISO and CE certificates. [4]

Editorial note: each syringe fits named injector models; confirm the compatibility list against your installed injectors, and confirm the registration status in your market before purchase.

03

Buyer questions

What pressure does a CT injector syringe need to withstand?

One FDA-cleared CT injector has a 325 psi maximum pressure limit; supplier syringes are listed at 350 psi and 600 psi. [1] [3] [4]

How are contrast injector syringes regulated in the US?

Under 21 CFR 870.1650, angiographic injector and syringe, Class II, product code DXT, in the FDA clearance reviewed. [1]

What does a CT syringe kit include?

One listing includes a 200 mL syringe, a 1,500 mm coiled connecting tube and a quick-fill tube, EO-sterilised for single use. [3]

Sources and what still needs a direct check

Sources checked 2026-10-11. The FDA 510(k) summaries describe cleared CT injector systems and their syringes; LnkMed and WEGO describe their own products. Compatibility and ratings for your order must come from the supplier's validation for your injector model.
