Reusable SpO2 sensors for GE: DS100A and the TruSignal line — selection, care and purchasing
Reusable SpO2 sensor DS100A and the TruSignal finger sensor (TS-SA-D) for GE monitors: how they work, selection, care, replacement and purchasing for Russia.
Reusable SpO2 sensors for GE: DS100A and the TruSignal line — selection, care and purchasing
Pulse oximetry (SpO2) is a non-invasive method of continuously monitoring blood oxygen saturation. It is one of the basic measurements in patient monitoring during anesthesia, in resuscitation and in intensive care.
In this guide we examine the reusable SpO2 sensors from the MediAccessori catalog — DS100A and the finger sensor TS-SA-D (TruSignal) — how they work, selection, care and purchasing.
1. How pulse oximetry works
A pulse oximeter shines light of two wavelengths — red and infrared — through tissue (usually a finger). Oxygen-saturated hemoglobin absorbs these wavelengths differently. The saturation SpO2 is calculated from the ratio of absorption in the pulsating (arterial) component.
A transmission (finger) sensor consists of a light emitter (LED) and a photodetector positioned opposite each other.
2. Key sensor parameters
- •Type — finger (transmission) or reflectance.
- •Design — reusable or disposable.
- •Patient category — adult / pediatric / neonatal.
- •Connector and standard — compatibility with the specific monitor.
- •Cable length — determines the radius of use.
3. Item breakdown
3.1. DS100A — reusable SpO2 sensor
PN: DS100A
Category: reusable SpO2 sensor.
- •Reusable design, intended for disinfection between patients.
- •Selected by monitor model and connector type.
- •Economical under intensive use.
3.2. TS-SA-D — GE TruSignal SpO2 sensor (finger, reusable, 1 m)
PN: TS-SA-D
Category: reusable finger SpO2 sensor.
- •GE TruSignal line.
- •For adults, finger type, transmission type.
- •Reusable, cable length 1 m.
- •Selected by monitor model.
4. Reusable or disposable?
| Aspect | Reusable (DS100A, TS-SA-D) | Disposable |
|---|---|---|
| Cost per patient | lower under intensive use | higher |
| Disinfection | required between patients | not required |
| Hygiene | depends on processing | maximum |
| Cross-infection | risk with poor processing | excluded |
| Scope | inpatient, long-term monitoring | septic/infectious patients, emergency care |
The choice depends on the department's protocol and the patient category.
5. How to select an SpO2 sensor
- •Determine the monitor model and the sensor connector standard.
- •Choose the patient category (adult/pediatric/neonatal).
- •Choose the type (finger) and design (reusable).
- •Verify the cable length (for example 1 m for TS-SA-D).
Sensor compatibility with the monitor is strict. Before ordering, send the monitor model to the engineer.
6. Care of a reusable sensor
- •Disinfect between patients according to the manufacturer's instructions.
- •Avoid immersing the optical part in liquid.
- •Do not use aggressive solvents.
- •Watch the integrity of the cable and connector.
- •Store in a clean, dry place.
7. Diagnosing incorrect readings
- •Check the fit and size of the sensor.
- •Make sure the limb has good perfusion.
- •Rule out nail polish/dirt on the nail bed.
- •Check the integrity of the cable and the connection.
- •If the error persists — replace the sensor.
8. Compatibility table
| PN | Item | Application | Note |
|---|---|---|---|
| DS100A | reusable SpO2 sensor | saturation monitoring | verify the monitor model and connector |
| TS-SA-D | TruSignal, finger, reusable, 1 m | adults, SpO2 monitoring | verify the monitor model |
Exact compatibility depends on the platform. Before ordering, send the device model.
9. Common mistakes
- •Selecting without the monitor model. SpO2 sensors are tied to the standard/connector.
- •Unsuitable size. An oversized finger sensor fits poorly and produces artifacts.
- •Poor processing of reusable sensors. Risk of cross-infection.
- •Ignoring the condition of the cable. A damaged cable produces false readings.
10. Delivery and purchasing
MediAccessori supplies original and compatible SpO2 sensors to Russia and the CIS:
- •The delivery time is confirmed when the order is confirmed.
