Multi-sensory feedback injection training device
In embodiments herein, a resettable injection training device is provided including an outer housing, an inner housing, said inner housing moving relative to the outer housing during actuation and reset, a tactile feedback indicator and/or a visual feedback indicator, wherein actuation of the device delivers a tactile and/or visual feedback; and a reset cap for resetting the device to a reset position, such that the reset cap resets the tactile and or feedback indicator to a pre-use position, for a subsequent use.
1. A resettable injection training device for simulating an injection, comprising:
an outer housing comprising a proximal end and a distal end, the proximal end comprising an aperture;
an inner housing comprising a protrusion for extending through the aperture during use of the device;
a first spring for interfacing with the inner housing,
a plunger for moving relative to the inner housing from a proximal end to a distal end, said plunger comprising a ramped portion;
a safety shield comprising a distal end for engaging with a target surface, said safety shield comprising a retracted position, an extended unlocked position and an extended locked position;
a rotating member for interfacing with the inner housing, said rotating member comprising an inner tab and an outer tab, wherein said rotating member rotates in a first direction during actuation and in a second direction during reset;
a second spring for interfacing with the rotating member;
wherein the inner housing, outer housing, first or second spring, plunger, safety shield and/or rotating member provides visual or tactile feedback; and
a reset cap comprising an elongated rod for resetting the device from a post-actuation position to a pre-actuation position.
2. The resettable injection training device of claim 1 , wherein the outer housing comprises an indicator window for indicating a status of the device during an injection simulation.
3. The resettable injection training device of claim 1 , wherein the outer tab of the rotating member interfaces with the inner housing to maintain the inner housing in a pre-actuation or reset position.
4. The resettable injection training device of claim 3 , wherein the inner tab of the rotating member interfaces with the ramped portion of the plunger during actuation of the device to rotate the rotating member in the first direction to disengage the outer tab from the inner housing, releasing the inner housing to move in a proximal direction.
5. The resettable injection training device of claim 4 , wherein the inner housing further comprises an inner housing groove for interfacing with the outer tab of the rotating member when the device is in the pre-actuation or reset position.
6. The resettable injection training device of claim 5 , wherein disengagement of the rotating member from the inner housing causes the second spring to activate, moving the rotating member distally.
7. The resettable injection training device of claim 4 , wherein distal movement of the plunger during actuation of the device releases the rotating member outer tab from the inner housing groove.
8. The resettable injection training device of claim 1 , wherein the second spring comprises a compression spring.
9. The resettable injection training device of claim 1 , wherein the first spring comprises a compression spring.
10. The resettable injection training device of claim 1 , wherein a force on the safety shield moves the safety shield from an extended, unlocked position to a retracted position to actuate the device.
11. The resettable injection training device of claim 10 , wherein movement of the safety shield to a retracted position releases the plunger, such that the plunger travels toward the distal end of the device.
12. The resettable injection training device of claim 1 , wherein rotation of the rotating member in the first direction allows the first spring to advance the inner housing toward the proximal end.
13. The resettable injection training device of claim 1 , wherein rotation of the rotating member in the first direction allows the second spring to advance the rotating member toward the distal end.
14. The resettable injection training device of claim 12 , wherein the protrusion extends through the aperture providing visual and/or tactile feedback of completion of a simulation.
15. The resettable injection training device of claim 1 , wherein during resetting the device, insertion of the reset cap into the distal end of the device causes the plunger to move proximally, causing proximal movement of the rotating member.
16. The resettable injection training device of claim 15 , wherein during reset, an interface between the ramped portion of the plunger and the inner tab of the rotating member causes the rotating member to rotate in the second direction until the outer tab interfaces with the inner housing groove.
17. The resettable injection training device of claim 16 , wherein the second spring causes the inner housing to move distally to reset the device by interface of the rotating member and the inner housing.
18. The resettable injection training device of claim 17 , wherein the outer housing comprises an indicator window for indicating a status of the device during an injection simulation, wherein distal movement of the inner housing resets the indicator window for a subsequent use.
19. The resettable injection training device of claim 1 , wherein the second spring comprises a greater force than the first spring.
20. The resettable injection training device of claim 1 , wherein a force on the distal end of the safety shield causing movement of the safety shield from an extended unlocked position to a retracted position causes a first audible signal during actuation to indicate initiation of actuation.
21. The resettable injection training device of claim 1 , wherein completion of distal plunger movement, rotation of the rotating member in the second direction, and proximal movement of the inner housing is accompanied by a second audible signal to indicate completion of an injection simulation.
