Saxsons™ Shielded Infusion Pump Shieldβ / γ Hybrid Cabinet for Lu-177 PRRT, Y-90 and I-131 Patient Infusion
Saxsons own-brand shielded cabinet that wraps the patient-side syringe pump and the radioactive syringe for the duration of the infusion. A configurable shielding-tier ladder covers the theranostic spectrum — lead-only tiers for routine SPECT, I-131 oral-solution and PET dispensing work, plus a β/γ hybrid variant that absorbs the Lu-177 / Y-90 beta before it reaches the lead, in the bremsstrahlung-minimising order that matters for the highest-dose phase of PRRT. Acrylic outer chassis, engraved lead-glass viewing window for tubing and flow inspection, IV-pole-cut variant for cart-mounted patient transport. ISO 9001 / ISO 13485 manufactured. Designed and manufactured in India by Saxsons Healthcare Pvt. Ltd. Sign in to view the full configuration matrix.
Key Features
- β / γ hybrid variant places a low-Z β-absorber inner layer inside the lead outer — the right shielding order for Lu-177 and Y-90: the low-Z layer absorbs the beta BEFORE it reaches the lead, eliminating the bremsstrahlung source; the lead outer layer then catches the primary Lu-177 113 / 208 keV gamma and any residual photons
- Lead-only variants for Tc-99m / I-131 oral-solution / lower-energy work where bremsstrahlung is not the dominant pathway — the right chassis weight for the right isotope class
- Configurable chassis form factors covering compact, standard and taller pump layouts, plus a high-volume syringe-well option for the PRRT infusion line
- High-volume syringe-well variant sized for the PRRT infusion line — the standard 7.4 GBq Lu-177 DOTATATE dose is delivered in a 50 mL infusion over ~30 minutes
- Engraved lead-glass viewing window lets the operator monitor the infusion flow, the syringe pump display and the patient tubing without unshielding the source

Applications
The cabinet for the highest-dose phase of theranostic therapy — patient administration
Lu-177 DOTATATE / PSMA-617 PRRT infusion
The standard 7.4 GBq Lu-177 dose is delivered over ~30 minutes via syringe pump into a slow IV drip. The β/γ hybrid variant wraps the pump and syringe — the low-Z inner absorbs the β before it reaches the lead, the lead outer catches the 113 / 208 keV γ. Published staff dose for PRRT administration is dominated by this step (Riveira-Martin 2023: 69 % of total staff dose in 19 % of procedure time). The cabinet is built for exactly that phase.
Y-90 microsphere or peptide infusion
Y-90 is essentially pure β (E_max 2.28 MeV). Raw lead in the β path generates bremsstrahlung at clinically meaningful rates. The β/γ hybrid variant is the right shielding order: low-Z inner first to absorb the β with minimal bremsstrahlung; lead second to handle anything else. Inverting the order — lead first — generates the worst-case bremsstrahlung the shield is supposed to prevent.
I-131 oral-solution decant and administration
I-131 at 364 keV is a lead-only pathway. The lead-only variant family covers the syringe-pump-driven oral-solution route used in some I-131 therapy workflows (paediatric, dysphagia, repeat fractionated dosing) in the right chassis form factors.
Routine Tc-99m / Tl-201 line infusion
At low-energy SPECT photopeaks, lead-only shielding in a compact form factor is sufficient. The compact lead-only variant fits the routine SPECT-isotope IV-line-shielding use case at lower chassis weight.
Bedside patient transport
The IV-pole-cut β/γ variant lets the cabinet ride on a standard IV pole from the radiopharmacy hot lab to the patient bedside or back to the ward — keeping the infusion shielded across corridor traverse and minimising the staff dose attributed to transport.
AERB-licensed theranostic suite
A theranostic-suite licence application has to identify the shielded equipment for each patient-administration step. The variant matrix lets the AERB licensee map per-isotope work onto a specific tier with traceable specs and ISO documentation.
Why Saxsons™ Shielded Infusion Pump Shield?
For Lu-177 and Y-90 the shielding order matters as much as the total thickness. A low-Z absorber inside stops the β with minimal bremsstrahlung; high-Z (lead) outside catches the residual γ and any bremsstrahlung that did get through. Inverted order — lead first — turns the lead into a bremsstrahlung source. The β/γ hybrid variant is built in the correct order; the low-Z absorber is the inner wall, the lead is the outer wall.
Riveira-Martin et al. (EJNMMI Physics 2023) measured 32 administrations of 7.4 GBq Lu-177 DOTATATE across 2 physicians and 4 nurses. Result: the administration step alone — patient-side, infusion pump running — accounted for 69 % of the total staff dose, even though it was only 19 % of the procedure time. This cabinet wraps exactly that step. Shielding the dispensary alone leaves the dominant dose pathway unprotected.
One-size-fits-all leaves you either over-shielded (chassis weight, transport ergonomics) or under-shielded (operator extremity dose). The variant matrix — lead-only tiers for SPECT / I-131 / lower-energy work, plus the β/γ hybrid — lets the radiopharmacist pick the right tier per isotope class, with the same lead-glass viewing window and the same acrylic chassis family across the matrix.

FAQ
Shielded infusion-pump cabinet — questions we hear from Indian theranostic teams
Why therapy infusions need shielding across the full delivery time, when to pick the β / γ hybrid variant for Lu-177 / Y-90, what the IV-pole-cut variant enables, and how the cabinet fits standard pump makes.
Q.Why do Lu-177 PRRT, Y-90 and I-131 infusions need a shielded pump cabinet rather than just a shielded syringe?
Therapy-scale infusions run 20–90 minutes with the full patient dose held in the syringe or IV bag on the infusion pump. Across that time the pump sits next to the patient bed, the nursing staff, and any family in the room. A shielded pump cabinet contains the entire pump + dose during the infusion — shielding the patient environment for the duration of the delivery, not just for the transit. On a 7.4 GBq Lu-177 PRRT dose that is the difference between a routine infusion and a room-scale dose incident.
Q.When does the department need the β / γ hybrid variant rather than lead-only?
Lu-177, Y-90, Sr-89 and P-32 emit beta particles alongside (or instead of) gamma. Pure-lead shielding on a beta emitter produces bremsstrahlung — secondary X-rays from beta deceleration in the lead — which then irradiates the patient environment. The β / γ hybrid variant uses a low-Z β-absorber inner (Perspex / PMMA / acrylic) to stop the beta before it reaches the lead, then the lead outer wall attenuates the gamma. Correct architecture for Lu-177 PRRT, Y-90 microsphere and Y-90 antibody infusions.
Q.What is the IV-pole-cut variant for?
Some therapy protocols wheel the shielded pump on the patient IV pole from the infusion room to a recovery bay after the therapy dose is administered — the residual activity in the tubing continues to decay after the bulk dose is delivered but still needs shielding. The IV-pole-cut variant has a back-panel cutout that mounts to the IV pole so the cabinet becomes cart-mounted for patient-transport shielding.
Q.Does the cabinet fit standard infusion-pump makes?
Yes — the cabinet is sized for standard clinical infusion-pump form factors used across Indian NM therapy suites. The tall-pump lead-only and standard variants match the common pump geometries; the high-volume syringe well fits the standard 50 mL infusion syringe used for 7.4 GBq Lu-177 PRRT delivery.
Q.Is this a distributor-supplied cabinet or Saxsons-manufactured?
The Infusion Pump Shield is a Saxsons own-brand product — designed and manufactured in India by Saxsons Healthcare Pvt. Ltd. The variant ladder (lead-only, β / γ hybrid, IV-pole-cut), pump-fit geometry and high-volume syringe well are engineered for the Lu-177 / Y-90 / I-131 therapy infusion workflows of Indian NM theranostic and endocrinology therapy programmes.
