Intended Use

The Instrumentation Industries, Inc. RTC 24-V MDI Adapter is an actuator for intermittent delivery of prescribed aerosol medication dispensed in cylindrical-style metered dose inhalers. The RTC 24-V MDI Adapter is intended for use only when connected to ventilator tubing or tracheal tubes. The RTC 24-V MDI Adapter is intended to be prescribed for any patient who is ventilator-dependent and to whom a metered dose inhaler has been prescribed. The expected clinical environment for the RTC 24-V MDI Adapter is Critical Care and/or long term or short term ventilation. The RTC 24-V MDI Adapter is intended for single patient reuse. This device is intended for sale by or on the order of a physician. The Instrumentation Industries, Inc. RTC 24-V KIT includes the RTC 24-V MDI Adapter actuator for intermittent delivery of prescribed aerosol medication dispensed in cylindrical-style metered dose inhalers. The RTC 24-V KIT is intended for use only when connected to ventilator tubing or tracheal tubes. The RTC 24-V KIT is intended to be prescribed for any patient who is ventilator-dependent and to whom a metered dose inhaler has been prescribed. The expected clinical environment for the RTC 24-V KIT is Critical Care and/or long term or short term ventilation. The components of the RTC 24-V KIT consist of one RTC 24-V MDI Adapter, one four inch length of 22 mm inner-diameter tubing, and one 15 mm inner-diameter/22 mm outer-diameter adapter. The RTC 24-V KIT is intended for single patient reuse. This device is intended for sale by or on the order of a physician.

Device Story

The RTC 24-V is an actuator for delivering aerosolized medication from cylindrical metered dose inhalers (MDIs) into ventilator circuits or tracheal tubes. It features an integrated gear mechanism designed to interface with specific MDI brands that include dose counters, allowing for monitoring of remaining medication. The device is used in critical care or ventilation settings by respiratory therapists or clinicians. It is provided as a standalone adapter or as a kit including 22mm tubing and a 15mm/22mm connector. The device facilitates medication delivery to ventilator-dependent patients, potentially improving therapeutic efficiency compared to previous models.

Clinical Evidence

Bench testing only. Laboratory performance compared the RTC 24-V to the RTC 22-D using Ventolin HFA, Atrovent HFA, and QVAR. Metrics included MMAD, GSD, and medication captured on USP throat. Results showed no statistically significant differences in particle size or throat deposition, while the RTC 24-V demonstrated statistically significant improvements in total dose delivered, respirable fraction, and total respirable dose delivered.

Technological Characteristics

Actuator for MDI; materials: Polystyrene Butadiene (body), Thermoplastic Rubber (cap). Dimensions: 15mm I.D. inlet, 15mm I.D./22mm O.D. outlet. Features integrated gear for MDI dose counter compatibility. Flow direction indicated by molded-in arrow. Single patient reuse. Latex-free.

Indications for Use

Indicated for ventilator-dependent patients prescribed aerosol medication via cylindrical-style metered dose inhalers. Used in critical care, long-term, or short-term ventilation settings. Prescription use only.

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.

| Technological<br>Characteristics | Similarities: The function, inlet and outlet end dimensions, and the materials of both the<br>RTC 22-D predicate device and the RTC 24-V are the same. Both the RTC<br>22-D and the RTC 24-V will accept plastic or metal tipped, cylindrically-<br>shaped MDI canisters. All materials are latex-free.<br>Materials - Body - Polystyrene Butadiene<br>Cap - Thermoplastic Rubber<br>Functional Dimensions - Inlet - 15mm I.D<br>Outlet - 15mm I.D./22 mm O.D.<br>Markings - Both the RTC 24-D and the RTC 22-D are marked with a molded-in arrow defining direction of flow. |
| | Differences: The RTC 24-V design includes a gear that is designed to mate with a limited<br>number of brands of metered dose inhalers that have an integral dose counter.<br>The interaction of the adapter gear and the dose counter permits accurate |
| | monitoring of the amount of doses remaining in the inhaler device. The RTC<br>22-D does not include a similar gear. |
| | There currently is not a kit version of the RTC 22-D. Users must purchase the<br>MDI adapter, the tubing and the straight connector separately. |
| Aerosol<br>Performance | The RTC 24-V was tested in the laboratory with the following MDI<br>medications:<br>- Ventolin® HFA<br>- Atrovent® HFA<br>- QVAR® |
| | In the tests (shown below) that were performed upon the RTC 24-V and the<br>RTC 22-D predicate device, actual differences were not statistically<br>significant:<br>Particle Size (MMAD)<br>Geometric Standard Deviation (GSD)<br>Medication Captured on USP Throat |
| | In the tests (shown below) that were performed upon the RTC 24-V and the<br>RTC 22-D predicate device, actual differences were statistically significant,<br>with the RTC 24-V out-performing the RTC 22-D.<br>Total Dose Delivered<br>Respirable Fraction<br>Total Respirable Dose Delivered<br>Medication Retained in Device |
| Conclusion: | In laboratory testing the RTC 24-V is substantially equivalent to the RTC 22-D<br>predicate device. |
