Noise and vibration dampening mounting module for injector
An independent mounting module is receivable within a housing of an injector configured to dispense a substance from a cartridge insertable into the housing through an injection needle of the injector. The mounting module includes a first mount and a second mount. The first mount is configured to receive a driving assembly engageable with the cartridge to expel the substance therefrom. The first mount is selectively securable to the injector housing and has a cantilevered mounting arm extending therefrom. The second mount is configured to receive an actuator operatively connectable with the driving assembly. The second mount is attached to the cantilevered mounting arm and suspended therefrom, thereby being supported by the cantilevered mounting arm.
1. An injector comprising:
an injector housing configured to receive a cartridge therein;
an injection needle fluidly connectable with the cartridge and configured to pierce a skin surface of a subject;
an independent mounting module receivable within the injector housing, the mounting module comprising:
a first mount selectively securable to the injector housing and the first mount having a cantilevered mounting arm extending therefrom; and
a second mount attached to the cantilevered mounting arm and suspended therefrom, thereby being supported by the cantilevered mounting arm;
a driving assembly mounted in and supported by the first mount, the driving assembly being engageable with the cartridge to expel a substance therefrom and through the injection needle;
an actuator mounted in the second mount, the actuator being operatively connected with the driving assembly; and
a battery mounted in the injector housing and connected to the actuator via a flexible electrical contact to power the actuator, whereby malleability of the flexible electrical contact contributes to absorbing vibration of the actuator.
2. The injector of claim 1 , further comprising a transmission gear connecting the actuator with the driving assembly.
3. The injector of claim 2 , wherein the cantilevered mounting arm is also configured to receive the transmission gear.
4. The injector of claim 1 , wherein the first mount comprises a sleeve slidably receiving the driving assembly.
5. The injector of claim 1 , wherein the second mount comprises a sleeve slidably receiving the actuator.
6. The injector of claim 1 , wherein the actuator is a motor.
7. The injector of claim 1 , further comprising at least one vibration reducing pad mounted between the actuator and the second mount.
8. The injector of claim 1 , further comprising a mounting plate configured to selectively, secure the independent mounting module to the injector housing.
9. The injector of claim 8 , wherein the mounting plate flexibly extends from the first mount.
10. The injector of claim 8 , wherein the mounting plate is selectively, removably securable to the injector housing.
11. The injector of claim 1 , wherein the first mount is selectively, removably securable to the injector housing.
12. An injector comprising:
an injector housing configured to receive a cartridge therein;
an injection needle fluidly connectable with the cartridge and configured to pierce a skin surface of a subject;
an independent mounting module receivable within the injector housing, the mounting module comprising:
a first mount, selectively securable within the injector housing, and having a cantilevered mounting arm extending therefrom; and
a second mount attached to the cantilevered mounting arm and suspended therefrom, thereby being supported within the injector housing by the cantilevered mounting arm without additional underlying support from the housing;
a driving assembly mounted in and supported by the first mount, the driving assembly being engageable with the cartridge to expel a substance therefrom and through the injection needle; and
an actuator mounted in the second mount, the actuator being operatively connected with the driving assembly.
13. The injector of claim 12 , wherein the independent mounting module further comprises a transmission gear connecting the actuator with the driving assembly.
14. The injector of claim 12 , wherein the first mount comprises a sleeve slidably receiving the driving assembly.
15. The injector of claim 12 , wherein the second mount comprises a sleeve slidably receiving the actuator.
16. The injector of claim 12 , wherein the injector includes a cradle structure configured to receive the first mount.
17. The injector of claim 12 , further comprising at least one vibration reducing pad mounted between the actuator and the second mount.
18. The injector of claim 12 , further comprising a power source, and wherein the actuator is connected to the power source via a flexible electrical contact.
19. An injector comprising:
an injector housing configured to receive a cartridge therein;
an injection needle fluidly connectable with the cartridge and configured to pierce a skin surface of a subject;
an independent mounting module receivable within the injector housing, the mounting module comprising:
a first mount, selectively securable within the injector housing, and having a cantilevered mounting arm extending therefrom; and
a second mount attached to the cantilevered mounting arm and suspended therefrom, thereby being supported within the injector housing by the cantilevered mounting arm without additional underlying support from the housing, thereby dampening transmission of vibration to the injector housing;
a driving assembly mounted in and supported by the first mount, the driving assembly being engageable with the cartridge to expel a substance therefrom and through the injection needle;
an actuator mounted in the second mount; and
a transmission gear mounted to the mounting module and connecting the actuator with the driving assembly.
20. The injector of claim 19 , wherein the injection needle is at least partially positioned within the injector housing.
