Achilles EXPII ultrasound densitometer: membrane assembly LU43996 — replacement and purchasing
Membrane assembly LU43996 for the Achilles EXPII ultrasound bone densitometer: purpose, signs of wear, replacement and purchasing of the original for Russia.
Achilles EXPII ultrasound densitometer: membrane assembly LU43996 — replacement and purchasing
Ultrasound densitometry is a non-invasive method of assessing bone density, widely used for diagnosing osteoporosis. An Achilles-type device measures the speed at which ultrasound travels through the calcaneus, which correlates with bone density.
In this guide we look at a replaceable component — the membrane assembly LU43996 for the Achilles EXPII densitometer — its role, the signs of wear, replacement and purchasing.
1. How the Achilles ultrasound densitometer works
The device uses an ultrasound transducer that is applied to the patient's heel. An ultrasound signal is passed through the calcaneus, and the receiving transducer records the speed at which it travels. Bone density parameters are calculated from the propagation speed and the attenuation of the signal (for example SOS — speed of sound, BUA — broadband ultrasound attenuation).
The key condition for a correct measurement is stable acoustic contact. That is exactly what the membrane assembly between the transducer and the heel provides.
2. The role of the membrane assembly LU43996
The membrane assembly performs several functions:
- It provides acoustic contact between the transducer and the patient's heel.
- It transmits the ultrasound signal without excess attenuation.
- It protects the transducer from moisture, gel and contamination.
- It maintains compression of the heel for stable contact.
A worn or damaged membrane distorts the signal and reduces diagnostic accuracy.
3. The LU43996 item
PN: LU43996
Category: membrane assembly for the Achilles EXPII ultrasound densitometer.
- •A replaceable membrane assembly to provide acoustic contact.
- •It belongs to the "other" equipment category in the Medicaparts catalogue.
- •Selected by densitometer model and generation of the assembly.
4. Signs of wear or damage
- •Reduced accuracy and repeatability of measurements.
- •Errors/failures during scanning.
- •Visible damage, cracks or a rupture of the membrane.
- •Deterioration of acoustic contact (unstable values).
If these signs appear, the membrane assembly should be replaced.
5. How to replace the membrane assembly
- Disconnect the densitometer from the mains.
- Remove the old membrane assembly.
- Clean the seating surface of gel residue and contamination.
- Fit the new LU43996 assembly, observing the orientation and the fixings.
- Switch the device on and take a control measurement to check the contact.
Replacement is carried out by trained/service personnel.
6. Service recommendations
- •Check the integrity of the membrane periodically.
- •Use gel of the appropriate type.
- •Follow the consumable replacement schedule in the device manual.
- •Keep a spare membrane assembly to prevent downtime.
7. Compatibility table
| PN | Item | Equipment type | Note |
|---|---|---|---|
| LU43996 | membrane assembly | Achilles EXPII ultrasound densitometer | check the model and the assembly generation |
Exact compatibility depends on the model. Before ordering, send the device model to an engineer.
8. Common mistakes
- •Buying without the device model. Assemblies are tied to the densitometer model.
- •Using a damaged membrane. It reduces diagnostic accuracy.
- •Fitting without cleaning the surface. Gel residue degrades the contact.
- •Ignoring the replacement schedule. Wear happens gradually and is not always noticeable.
9. Delivery and purchasing
Medicaparts supplies membrane assemblies and spare parts for diagnostic equipment to Russia and the CIS:
