Abstract

Medicament delivery devices are described herein. In some embodiments, an apparatus includes a medicament delivery device and an electronic circuit system. The medicament delivery device includes a housing, a medicament container, and a medicament delivery member. The electronic circuit system is coupled to the housing and includes an audible output device and a cover. The housing of the medicament delivery device and the cover of the electronic circuit system collectively define an acoustic enclosure. The audible output device is configured to be disposed within the acoustic enclosure.

Claims

1. An apparatus, comprising:

a simulated medicament delivery device devoid of a medicament delivery mechanism that causes a medicament to be delivered, the simulated medicament delivery device including a housing; and

an electronic circuit system coupled to the housing, the electronic circuit system including an audible output device and a cover, a first portion of the audible output device configured to produce a first plurality of sound waves, a second portion of the audible output device configured to produce a second plurality of sound waves having a phase difference with the first plurality of sound waves, the housing and the cover collectively defining an acoustic enclosure, at least one of the housing or the cover defining a first opening, at least one of the housing or the cover defining a second opening,

the audible output device configured to be disposed within the acoustic enclosure such that the first plurality of sound waves travels from the first portion of the audible output device to a region outside of the housing via the first opening and the second plurality of sound waves travels from the second portion of the audible output device to the region outside of the housing via the second opening,

the second opening spaced apart from the first opening such that the phase difference between the first plurality of sound waves and the second plurality of sound waves is shifted when the first plurality of sound waves exits the first opening and the second plurality of sound waves exits the second opening.

2. The apparatus of claim 1, wherein:

the audible output device is a speaker, the speaker includes a front portion and a back portion, the front portion of the speaker configured to output a first audible output including a first plurality of sound waves, the back portion of the speaker configured to output a second audible output including a second plurality of sound waves;

the cover defines a first opening through which the first plurality of sound waves is configured to travel; and

the housing defines a second opening through which the second plurality of sound waves is configured to travel,

the first second opening and is spaced apart from the second first opening collectively configured such that the first plurality of sound waves are is substantially in phase with the second plurality of sound waves when the first plurality of sound waves exits the first opening and the second plurality of sound waves exits the second opening.

3. The apparatus of claim 1, wherein the acoustic enclosure defines at least one acoustic resonant frequency within the acoustic frequency range of the audible output device.

4. The apparatus of claim 1, wherein the audible output device is a speaker configured to output an audible output having a sound pressure level greater than about 61 decibels.

5. The apparatus of claim 1, wherein the audible output device is a speaker configured to output an audible output having a sound pressure level greater than about 61 decibels at a distance of about 6 inches from the speaker.

6. The apparatus of claim 1, wherein the audible output device is a speaker configured to output an audible output having a sound pressure level greater than about 61 decibels within a distance of about 20 feet from the speaker.

7. The apparatus of claim 1, wherein:

the electronic circuit system is configured to output to the audible output device an electronic signal having a power of less than 100 milliwatts; and

the audible output device is configured to output a recorded speech output in response to the electronic signal, the recorded speech output having a sound pressure level greater than about 61 decibels.

8. The apparatus of claim 1, wherein the audible output device is a speaker, the housing includes a spacer configured to be disposed adjacent the speaker such that a front portion of the speaker is in contact with a portion of the cover.

9. The apparatus of claim 1, wherein at least a portion of the housing that defines the acoustic enclosure includes a flexible wall.

10. An apparatus, comprising:

a simulated medicament delivery device devoid of a medicament delivery mechanism that causes a medicament to be delivered, the simulated medicament delivery device including a housing; and

an electronic circuit system coupled to the housing, the electronic circuit system including a speaker and a cover, the speaker includes a front portion and a back portion, the front portion of the speaker configured to output a first audible output including a first plurality of sound waves, the back portion of the speaker configured to output a second audible output including a second plurality of sound waves, the housing cover defining a first opening exit path through which the first plurality of sound waves is configured to travel from the front portion of the speaker to a region outside of the housing, the cover housing defining at least a portion of a second opening exit path through which the second plurality of sound waves is configured to travel from the back portion of the speaker to the region outside of the housing, a length of the first exit path different from a length of the second exit path such that the first plurality of sound waves is substantially in phase with the second plurality of sound waves when the first plurality of sound waves exits the first exit path and the second plurality of sound waves exits the second exit path.

11. The apparatus of claim 10, wherein the length of the first opening and exit path is less than the length of the second exit path opening are collectively configured such that the first plurality of sound waves are substantially in phase with the second plurality of sound waves when the first plurality of sound waves exits the first opening and the second plurality of sound waves exits the second opening.

12. The apparatus of claim 10, wherein:

the cover defines a first opening through which the first plurality of sound waves is configured to travel; and

the housing defines a second opening through which the second plurality of sound waves is configured to travel,

a distance between the first opening spaced apart from and the second opening has by a length distance of between about 2.5 inches and about 3 inches.

13. The apparatus of claim 10, wherein the second opening is configured to be selectively covered by a moveable member of the medicament delivery device.

14. The apparatus of claim 10, wherein the second opening is configured to be selectively covered by a moveable member of the medicament delivery device, the moveable member being at least one of a sleeve, a safety lock, or a needle guard.

15. The apparatus of claim 10, wherein the medicament delivery device includes a member movably coupled to the housing, the member configured to prevent the medicament delivery device from delivering a medicament when in a first position, a portion of the member disposed about within the second opening exit path when in the first position.
