Indications for Use
The Space Chamber Plus and Compact Space Chamber Plus are intended to be used by patients who are under the care or treatment of a licensed health care provider or physician. The devices are intended to be used by these patients to administer aerosolized medication from most pressurized Metered Dose Inhalers, prescribed by a physician or health care professional. The intended environments for use include home, hospitals and clinics.
Device Story
Space Chamber Plus and Compact Space Chamber Plus are valved holding chambers (VHCs) designed to assist patients in inhaling aerosolized medication from pressurized Metered Dose Inhalers (pMDIs). The device consists of a cylindrical chamber with an inhaler interface at one end and a mouthpiece (optionally used with a mask) at the other. A cross-slit valve system regulates airflow; the valve opens during inhalation and closes during exhalation, allowing the patient to visualize valve movement through the transparent chamber to confirm proper inhalation technique. The device is used by patients in home, hospital, or clinical environments. By providing a holding space for the aerosol, the device improves the respirable fraction of medication delivered to the patient compared to pMDI use alone, facilitating consistent dosing and effective treatment for respiratory conditions.
Clinical Evidence
Bench testing only. Particle size distribution testing (MMAD and respirable fraction) was conducted using three drug classes (ipratropium bromide, albuterol, beclomethasone dipropionate) to compare the subject devices against the predicate. Results showed equivalent respirable fractions and MMAD values with narrow 95% CIs, confirming consistent medication delivery. Additional testing included materials characterization, particulate analysis, drop testing, cleaning validation, and ISO 10993 biocompatibility testing (cytotoxicity, sensitization, irritation, genotoxicity, implantation).
Technological Characteristics
Valved holding chamber; cylindrical form factor; cross-slit valve system; compatible with standard pMDIs; mouthpiece or mask interface; transparent body for visual feedback; biocompatible materials (ISO 10993 compliant).
Indications for Use
Indicated for patients under the care of a licensed healthcare provider to administer aerosolized medication from pressurized Metered Dose Inhalers (pMDIs) in home, hospital, or clinical settings.
Regulatory Classification
Identification
A nebulizer is a device intended to spray liquids in aerosol form into gases that are delivered directly to the patient for breathing. Heated, ultrasonic, gas, venturi, and refillable nebulizers are included in this generic type of device.

The technological characteristics of the new devices are similar to the legally marketed predicate as summarised below:
The Space Chamber Plus, Compact Space Chamber Plus and the predicate all use a holding chamber and one-way valve system through which metered dose inhaler medication passes to the patient.
Particle size distribution testing confirms the substantial equivalence of respirable dose delivered to the patient between the proposed devices and the predicate.
Clinical Data:
The use of Valved Holding Chambers to assist with the administration of aerosolized medication is proven technology and is well accepted by the medical community. Non-clinical data is sufficient to demonstrate the safety and efficacy of the Space Chamber Plus and Compact Space Chamber Plus devices.

## Non-clinical Performance Data:
Evaluation of the new device and the predicate device was performed in accordance with the relevant sections of the CDRH Guidance Document "Reviewers Guidance for Nebulizers, Metered Dose Inhalers, Spacers and Actuators" (FDA/CDRH/ODF/DCRD/ADDB -1993).
Particle size distribution testing was performed using 3 drug classes ipratropium bromide (anti-cholinergic bronchodilator), albuterol (beta-agonist bronchodilator) and beclomethasone dipropionate (anti-inflammatory) comparing the Space Chamber Plus and Compact Space Chamber Plus with the predicate. The respirable fraction delivered by the spacers is greater than that delivered by the pMDI alone. The respirable fractions delivered by the Space Chamber Plus and Compact Space Chamber Plus are equivalent to those delivered by the predicate, Aerochamber Plus Flow Vu Anti-static. Likewise, the MMAD values obtained with Space Chamber Plus and Compact Space Chamber Plus are comparable to those obtained with Aerochamber Plus Flow Vu Antistatic. The 95% Cl is narrow for both the respirable fraction and MMAD results, indicating that medication doses can be consistently delivered by the spacers. Particle size distribution testing confirms the proposed devices to be substantially equivalent to the predicate device.

Particle size distribution testing was repeated post-cleaning. Performance testing demonstrates that the post-washed Space Chamber Plus and Compact Space Chamber Plus remain equivalent to the pre-washed devices and to the predicate device.
Other performance testing includes materials characterization, particulate analysis, drop test and cleaning validation.
ISO 10993 testing has been performed on the Space Chamber Plus components, including Cytotoxicity, Sensitization, Irritation, Genotoxicity and Implantation tests. The Space Chamber Plus and Compact Space Chamber Plus devices are made of identical materials; the Compact Space Chamber Plus is a smaller version of the Space Chamber Plus that allows for easier storage and handling.
Non-clinical and performance testing demonstrates that the Space Chamber Plus and Compact Space Chamber Plus devices raise no new issues of safety or effectiveness compared to the legally marketed predicate device.
Substantial Equivalence Conclusion:
The new devices, the Space Chamber Plus and Compact Space Chamber Plus, are considered to be substantially equivalent to the predicate device based on the following:
- . they have the same intended use and are indicated for the same user population:
- they have equivalent technological characteristics to the predicate: ●
- they do not raise any new questions of safety or effectiveness; .
- they are at least as safe and effective as the predicate. .
