The device description and intended use focus on a simple mechanical shield to reduce taste effect, with no mention of computational analysis, learning, or adaptive behavior.
No
Explanation: The device is intended to reduce the taste effect of MDI drugs by covering the tongue, not to treat or diagnose a disease or condition. It acts as a shield to prevent drug deposition on the tongue.
No
The device's intended use is to reduce the taste effect of Metered Dose Inhaler (MDI) drugs by covering the tongue. It does not analyze, measure, or interpret any physiological data to diagnose a medical condition.
No
The device description clearly describes a physical, single-patient-use device that attaches to an MDI elbow and shields the tongue. It discusses physical features like a universal clip and patient end variations, and mentions testing for structural integrity and choke hazards, all indicative of a hardware device.
Based on the provided information, the DHD MedShield is not an IVD (In Vitro Diagnostic) device.
Here's why:
- Intended Use: The intended use is to reduce the taste effect of MDI drugs by covering the tongue. This is a physical interaction with the patient's body to alter a sensory experience, not to diagnose a condition or provide information about a patient's health status based on in vitro examination of specimens.
- Device Description: The description focuses on the physical mechanism of shielding the tongue from medication spray and attaching to an MDI elbow. It describes a physical barrier and attachment mechanism, not a method for analyzing biological samples.
- Lack of IVD Characteristics: There is no mention of analyzing biological specimens (blood, urine, tissue, etc.), detecting analytes, or providing diagnostic information. The device's function is purely mechanical and related to drug delivery and taste perception.
Therefore, the DHD MedShield falls under the category of a medical device, but not specifically an In Vitro Diagnostic device.
N/A
Intended Use / Indications for Use

Device Description
The MedShield product reduces drug deposition in the tongue when used in conjunction with metered dose inhaler (MDI) medications. The device attaches to an MDI elbow and shields the tongue of the user from the medication spray. Drug that deposits on the device would otherwise be on the users tongue. Based on this, the taste effect of the medications is reduced.
This simple device includes two different features.
- The patient end of the device covers the tongue. The patient end may vary to maximize the comfort of a wide range of users.
- The elbow end of the device includes a universal clip, which attaches the device to all MDI elbows. To satisfy the preferences of various customers, the force required to separate (or attach) the device to various elbows can be modified by adjusting the clip or modifying the taper around the clip.
The MedShield product has been designed to conform with ASTM F963-92, "Standard Consumer Safety Specification on Toy Safety, under Section 4.6, Small Objects, specifically 4.6.2, Mouth-Actuated Toys, and CFR 16-1511.1, "Requirements For Pacifically, 1511.5 Structural integrity tests for Small Parts, 1511.5 (d), to ensure that the device does not present a choke hazard.
The MedShield is designed for single patient use. Patients may be given the product for use either in a hospital or home environment for extended time periods. Recommendations for cleaning, in cases of extended time, are included in the instructions for use.
As a prescription item, the labeling of the device contains the required caution statement: "Caution: Federal (USA) law restricts this device to sale by or on the order of a physician."

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Comparative Performance Testing: In each instance tested, the medication deposited on the MedShield was less than that with other devices are cylindrical providing significantly more surface area to collect medication. The lower values for MedShield indicate that only medication that would be deposited on the tongue is affected.
Nonclinical tests included:
Chemical Resistance: The plastic selected for the MedShield is an Acetal resin - Celcon M90. This material has been tested by the manufacturer (Hoeschet Celanese Corp.-Attachment 1) for the effect of various chemicals on physical properties (see tables provided). The three sodium compounds listed are found in dishwasher powders. The Freon, Alcohol and Oleic Acid compounds are found in MDI canisters.
Cleaning Test: MedShield units were soaked for 5 days in alcohol, dishwashing liquid and vinegar with no physical or cosmetic degradation noted. Units were subjected to 5 cycles of a standard dishwasher with no physical or cosmetic degradation noted. These are considered to be typical cleaning agents/conditions available to users.
Drop Test: MedShield units were dropped 10 times from a height of 1 meter onto a tile covered cement floor without breakage.

5. Intended Use
The DHD MedShield is a single-patient-use device. The Intended Use of the device is to reduce the taste effect of Metered Dose Inhaler (MDI) drugs by covering the tongue in the taste sensor area.
Technological Information 6.
MedShield, Microspacer and Aerochamber are used by attaching to a Metered Dose Inhaler (MDI) 6.1 elbow, placing part of the device in the mouth and administering the MDI. After activation of the MDI the user inhales the medication while keeping the device in the mouth.
MedShield attaches to the patient end of the MDI elbow via an integral clip. The patient end of the 6.2 MedShield masks the area of the tongue that it covers and medication that would have been deposited on that section of the tongue, is deposited on the MedShield.
Aerochamber attaches to the patient end of the MDI elbow via a flexible thermoplastic opening which 6.3 surrounds the outer diameter of the elbow patient end. A chamber is affixed to the opening which terminates in a valved mouthpiece at the patient end. After activation of the MDI, large particles impact and deposit within the walls and valving thereby reducing the amount released into the oral cavity of the patient.
Microspacer attaches to the patient end of the MDI elbow via a conical flexible opening. A small 6.4 (relative to Aerochamber) chamber is terminated by plastic grating at the patient end. After activation of the MDI, larger particles impact and deposit on the walls and grate reducing the amount released in the oral cavity of the patient.
6.5 Features and Specifications
MedShield is one piece and is positioned by on top of the patient's tongue. 6.5.1
Microspacer and Aerochamber have a patient end that serves as mouthpiece. The patient's lips 6.5.2 surround the mouthpiece and the patient then inhales through the device.
MedShield is opaque and approximately 1.5 inches by 2.5 inches, rectangular. 6.5.3
Microspacer is opaque and approximately a 1.75 inch long cylinder with a tapered diameter ranging 6.5.4 from 1.0 to 0.75 inches. The patient end of the cylinder contains an integral grate.
Aerochamber is opaque at each end and transparent in the center. The device consists of a 4.5 inch 6.5.5 long cylinder (1.75 inch inner diameter) with a 1.25 inch x 1.25 inch x 0.75 inch mouthpiece at the patient end and a flexible elliptical opening in which the MDI elbow is inserted.
A brief discussion of nonclinical tests conducted on this device and how the results support a 7. determination of substantial equivalent follows:
7.1 Environmental testing was completed to determine the effects of:
Chemical Resistance
The plastic selected for the MedShield is an Acetal resin - Celcon M90. This material has been tested by the manufacturer (Hoeschet Celanese Corp.-Attachment 1) for the effect of various chemicals on physical properties.

---|---|---|---|
Alcohols | Excellent | Freon | Excellent |
Ethyl Alcohol | Excellent | Oleic Acid | Good |
Methyl Alcohol | Excellent | Sodium Sulfate | Excellent |
Propyl Alcohol | Excellent | Sodium Carbonate | Good |
Trisodium Phosphate | Excellent |
Cleaning Test: MedShield units were soaked for 5 days in alcohol, dishwashing liquid and vinegar with no physical or cosmetic degradation noted. Units were subjected to 5 cycles of a standard dishwasher with no physical or cosmetic degradation noted. These are considered to be typical cleaning agents/conditions available to users.
Drop Test: MedShield units were dropped 10 times from a height of 1 meter onto a tile covered cement floor without breakage.
Comparative Performance Testing: In each instance tested, the medication deposited on the 7.2 MedShield was less than that with other devices are cylindrical providing significantly more surface area to collect medication. The lower values for MedShield indicate that only medication that would be deposited on the tongue is affected.
Based on the foregoing information, DHD believes the MedShield performs substantially equivalent to the predicate device(s) and in the opinion of DHD it is substantially equivalent to the predicate device(s) and does not adversely affect safety and effectiveness compared to the predicate device.
