A light-protected elastomeric infusion pump with a hard shell is a single-use pump that runs without electricity, for continuous infusion of light-sensitive cytotoxic drugs. The reservoir sits in a light-blocking rigid bottle, and the line and the accessories are protected from light too, so no separate sleeve is fitted. The drug flows through a flow restrictor tube at a constant rate.

A single-use elastomeric infusion pump with a rigid body whose reservoir, line and accessories are all protected from light: 100 and 275 ml, fixed rates of 1.5 to 5 ml/h.
| Factor | What the instructions for use say |
|---|---|
| Temperature | The stated rate was measured at room temperature (23 ± 2 °C) with water for injection, and temperature can change it. A refrigerated pump is brought to room temperature before use; a large-volume pump can take up to 12 hours. |
| Height | With the pump body above the flow restrictor, pressure and rate go up; below it, both go down. The hanging height relative to the patient can also change the rate. |
| Drug and diluent | The nominal rate holds with 5 per cent dextrose or 0.9 per cent sodium chloride as the diluent. The drug's composition and concentration, the fluid's viscosity and the injection pressure can change it. |
| Fill volume | Filling below or above the nominal volume generally makes the rate inaccurate; overfilling can also break the reservoir. |
| Time from filling to start | Infusion is preferably started 0 to 8 hours after filling; a filled pump kept longer than 8 hours can take longer to deliver. |
| First hours | In the first 1 to 2 hours of infusion the rate can be faster than stated. |

A patient going home with the pump can scan this code with a phone to open our home chemo pump guide. At discharge you can also print the A5 patient card and fill it in together.

A catalogue number writes the type, the volume, the flow rate and the filter pore together: NUCBI10040L12 is the light-protected rigid body at 100 ml, 4 ml/h and a 1.2 micrometre filter. Ten items are supplied.
The drug's own instructions for use and its label say whether it must be protected from light, and the hospital pharmacy keeps the list. For such drugs this pump protects the reservoir, the line and the accessories together.
The light protection is the same on both and covers the reservoir, the line and the accessories together. On the hard-shell type the reservoir sits in a light-blocking rigid bottle. On the soft-shell type the outer body takes less room in storage and in transport, and the infused volume is followed on the body of the pump.
No sleeve is fitted on this pump, because the reservoir, the line and the accessories are protected together. A light-protective sleeve covers a bag, a syringe or a line.
The price depends on the model, volume and quantity. The volume (100 and 275 ml), the flow rate and the filter pore make up the catalogue number. Use the Request an export quote button in the Export and Bulk Orders section of this page for a fast quote.
The reservoir, the tubing and the accessories are protected together, so no separate sleeve is fitted for the infusion.
Bottles of 100 ml and 275 ml, at 1.5, 2, 4 and 5 ml/h, one fixed rate per item. The models table gives the volume, the rate and the filter pore of every catalogue number.
The instructions for use do not cover showering; they say only that cleaning agents such as soapy water or alcohol must not touch the filter, which can then leak. Our patient guide tells the patient to shower only if the nurse allows it, to keep the pump in a plastic bag outside the shower and never to put the pump or the line in water.
If the pump body or one of its parts breaks or leaks, the instructions say to stop the infusion by clamping the tubing, inform the responsible caregiver and replace the pump if necessary. Our patient guide tells the patient to close the clamp, put on gloves, use the spill kit the hospital gave them and call the hospital straight away. The spilled drug is cleaned up under your unit's own spill procedure.
The mean rate stays within plus minus 10 per cent of the nominal rate and can be faster than stated in the first 1 to 2 hours. Temperature, the height of the pump body against the flow restrictor, the drug's composition, concentration and viscosity, a fill other than the nominal volume and a filled pump kept longer than 8 hours before the start can all change the time. At the end at most 3 ml stays behind, tubing included. Our patient guide tells the patient to call the hospital if the pump finishes much earlier than they were told, or is still full well after the expected time.
No. The pump is for single use: it is not used again and not re-sterilised. The instructions warn that reuse or re-sterilisation can make the flow unpredictable and cause infection in the patient. After use it is discarded under local regulations.
In a cool, dry and well-ventilated place, protected from moisture and direct sunlight. It is not frozen, because freezing can damage the tubing and the plastic parts. Shelf life is 5 years. A refrigerated pump is brought to room temperature before use; a large-volume pump can take up to 12 hours, and dew inside the case meanwhile does not affect its use.
