Description

IMPROVEMENTS IN OR RELATING TO INJECTOR DEVICES
This invention relates to an injector device.
It is known to deliver drugs through the skin, i.e. transdermally, by using a needle.
According to a first aspect of the invention there is provided an injector device comprising: a device body;
a needle moveable relative to the device body between a retracted position, in which the needle is fully housed within the device body, and an injected position, in which a portion of the needle is exposed beyond the device body;
a resiliently deformable member configured to deform from a start state to an end state via an intermediate state upon actuation thereof; and an injector mechanism operatively coupling the needle and the resiliently deformable member, the injector mechanism being configured to pull the needle from the retracted position to the injected position as the resiliently deformable member deforms from the start state to the intermediate state, the injector mechanism being further configured to continue to pull the needle from the injected position back to the retracted position as the resiliently deformable member continues to deform from the intermediate state to the end state.
The inclusion of such an injector mechanism means that the needle is injected and retracted into the device body upon a single actuation. This means that the needle is automatically hidden within the device body after use which may prevent needle injuries. Moreover, the injection and automatic retraction is provided by a single mechanism, which reduces the complexity of the device.
Therefore, the injector device of the invention permits the injection and retraction of a needle using a single mechanism and upon a single actuation.
The injector mechanism may include a guide member positioned between the resiliently deformable member and the needle, the injector mechanism may further include a coupling member attached to the needle and to the resiliently deformable member, the coupling member being configured to track along the surfaces of the guide member as the resiliently deformable member deforms from the start state to the end state.
Preferably, the coupling member includes a tracking portion positioned partway along the coupling member, the tracking portion being configured to track along a first surface of the guide member as the resiliently deformable member deforms from the start state to the intermediate state, and being configured to track along a second surface of the guide member as the resiliently deformable member further deforms from the intermediate state to the end state.
Such a configuration provides a simple means of pulling the needle from the retracted position to the injected position and back to the retracted position again.
More specifically, the coupling member may include a first coupling member portion attached to the needle, and a second couple member portion attached to the resiliently deformable member, the first and second coupling member portions being joined to one another at the tracking portion.
The second coupling member portion may be configured to track along the first surface of the guide member as the resiliently deformable member deforms from the start state to the intermediate state and is configured to track along the second surface of the guide member as the resiliently deformable member deforms from the intermediate state to the end state.
Furthermore, the first coupling member portion may be configured to track along the first surface of the guide member as the resiliently deformable member deforms from the start state to the intermediate state and is configured to slide along a bridging surface of the guide member when the resiliently deformable member deforms from the intermediate state to the end state, the bridging surface bridging the first and second surfaces of the guide member.
Optionally, the guide member extends along the device body such that it lies adjacent to the resiliently deformable member in the start state and the end state, and adjacent to the needle in the retracted position and the injected position.
The guide member extending along the device body in this manner means that its length spans the distance travelled by the resiliently deformable member as it deforms from the start state to the end state, and the distance travelled by the needle as it moves from the retracted position to the injected position. The guide member having such a length means that is can provide guiding support to both the resiliently deformable member and the needle in use.
In an embodiment of the invention, the injector device further includes a stop member releasably engaged with the device body and configured to prevent the resiliently deformable member from deforming from the start state to the end state until the stop member is released from the device body, wherein actuation of the resiliently deformable member occurs when the stop formation is released.
In such an embodiment of the invention, the injector device may include a release member located on the device body, the release member being configured to be depressed so as to release the stop formation and thus actuate the resiliently deformable member.
Such an arrangement provides a simple means for a user to press the release member (e.g. a button) so as to activate the injection and retraction of the needle.
The release member may be flush with the surrounding part of the device body.
The release member being flush with the surrounding part of the device body prevents accidental activation of the injector mechanism.
Preferably, in the start state the resiliently deformable member is in a deformed state and in the end state the resiliently deformable member is in a relaxed state. The resiliently deformable member may be a compression spring.
The resiliently deformable member being a compression spring makes use of the natural deformation of the compression spring to extend to its rest position to pull the injector mechanism, and thus the needle to the injected and retraction positions.
The needle may be configured to deliver a solid dose drug to a patient upon the needle exiting the device body.
According to second aspect of the invention there is provided a method of administering a drug to a patient using the injector device described hereinabove.
The drug may be a solid dose drug.
The advantages of the injector device of the first aspect of the invention and its embodiments applies mutatis mutandis to the method of the second aspect of the invention and its embodiments.
A preferred embodiment of the invention will now be described, by way of a non-limiting example, with reference to the accompanying drawings in which:
Figure 1 shows an injector device according to the invention;
Figure 2 shows the interior of the injector device of Figure 1; and
Figures 3a to d show the movement of the injector device components in use.
An injector device according to the invention is shown in Figures 1 to 3d and is designated generally by reference numeral 10.
The injector device 10 includes a device body 12 which, as shown in Figure 1, forms an outer casing 14 of the injector device 10. The device body 12 has an injector surface 16 with an opening 18 (shown in Figure 2) to allow a needle to exit the device body 12 to penetrate the skin of a patient.
As shown in Figure 2, the injector device 10 also includes a needle 20 which comprises of a needle hub 22 and a needle stick 24, the needle stick 24 being the part that penetrates the skin.
The needle 20 is in a retracted position in Figure 2 in which the needle 20 is fully housed within the device body 12. The needle 20 is moveable, in a linear fashion, relative to the device body 12 between the retracted position and an injected position in which a portion of the needle 20, in particular at least a portion of the needle stick 24, is exposed beyond the device body 12 (i.e. through the opening 18). The injected position of the needle 20 can be seen in Figure 3b.
The injector device 10 further includes a resiliently deformable member 26 which is attached at one end to the device body 12, and is configured to deform from a start state to an end state via an intermediate state upon actuation thereof. The resiliently deformable member 26 is housed within a casing 28 in the embodiment shown and the casing 28 is moveable with the resiliently deformable member 26 as it deforms.
The resiliently deformable member 26 can be seen in more detail in Figures 3a to 3d and in this embodiment the resiliently deformable member 26 is a compression spring 30 which is deformed in the start state (i.e. compressed -as shown in Figure 3a) and is relaxed in the end state (i.e. extended -as shown in Figures 3c and 3d).
In other embodiments of the invention (not shown), the resiliently deformable member 26 may take any other form which allows deformation from a start state to an end state.
The injector device 10 furthermore includes an injector mechanism 32 which operatively couples the needle 20 and the compression spring 30.
The injector mechanism 32 in the embodiment shown includes a guide member 34, in the form of an elongate rib 36, which is positioned between the compression spring 30 and the needle 20. The injector mechanism 32 also includes a coupling member 38 which is configured to track along the surfaces of the rib 36 as the compression spring 30 deforms from the start state to the end state.
In particular, the rib 36 includes a first surface 40a which lies adjacent to the needle 20 and a second surface 40b which lies adjacent to the compression spring 30. The rib 36 also includes a bridging surface 40c which bridges the first and second surfaces 40a, 40b of the rib 36, i.e. a top surface of the rib 36 as shown in Figure 2. The rib 36 also includes a curved rib end 37 joining the first and second surfaces 40a, 40b.
Meanwhile, as shown in more detail in Figure 3a, the coupling member 38 includes a first coupling member portion 42a which is attached to the needle 20 (in particular the needle hub 22) and a second coupling member portion 42b which is attached to the compression spring 30 (in particular the casing 28 of the spring 30). The first and second coupling member portions 42a, 42b are joined to one another at a tracking portion 44.
The first coupling member portion 42a and the second coupling member portion 42b, when the compression spring 30 is in the start state, run parallel with one another but are spaced from one another by the tracking portion 44.
The first and second coupling member portions 42a, 42b and the tracking portion 44 in the embodiment shown are integrally formed from a single piece of material, preferably a plastics material, but may instead be made from separate pieces of material which are joined to one another.
The rib 36 in the embodiment shown is integrally formed with the device body 12 and extends from a first end 46 of the device body 12 towards a second end 48 of the device body 12, the second end 48 having the injector surface 16 formed thereon. The rib 36 is spaced from the second end 48 of the device body 12 so as to leave a gap between the device body 12 and the rub 36 which allows the coupling member 38 to track around the curved rib end 37.
The rib 36 lies adjacent to and in parallel with the compression spring 30 and its casing 28 when the compression spring 30 is in the start state and the end state, and it lies adjacent to and in parallel with the needle 20 when the needle is in the retracted position and the injected position. The needle hub 22 and the casing 28 of the compression spring 30 are slidably engaged with respective first and second surfaces 40a, 40b of the rib 36.
The injector device 10 also includes a stop member 50 which is releasably engaged with the device body 12. The stop member 50 in the embodiment shown is a resiliently deformable portion 52 extending from the compression spring casing 28 which is biased away from the casing 28. Because the stop member 50 forms part of the casing 28, and the casing 28 is moveable with the compression spring 30, the stop member 50 prevents the compression spring 30 from deforming when the stop member 50 is engaged with the device body 12.
The injector device 10 further includes a release member 54 in the form of a release button 56 which is located on the device body 12 and is accessible from the outer of the device body 12. In the embodiment shown, the release button 56 is a resiliently deformable portion extending from the outer casing 14 which is biased away from the outer casing 14.
The stop member 50 abuts the outer casing 14 at the cut-out of the release button 56 so as to engage with the device body 12 and therefore hold the compression spring 30 in place in the start state.
Returning to Figure 1, the release button 56 is flush with the surrounding part of the outer casing 14. More specifically, the outer casing 14 includes grip portions 60 on opposing surfaces of the outer casing 14. The grip portions 60 each extend beyond the respective outer casing surfaces, and the release button 56 is located on the surface between the grip portions 60. In this way, the release button 56 is recessed between the protruding grip portions 60.
The injector device 10 also includes a plurality of small spikes 62 extending from the injector surface 16 which help to distract a patient from the needle injection.
The outer casing 14 also have a rounded first end 46 (i.e. the end opposite to the injector surface 16) to improve comfort of the injector device 10 when held.
In this regard, in use, a user (which may be the patient who is to be injected or another person such as a medical professional) holds the injector device 10 by gripping the device 10 at the grip portions 60 with the thumb on one side and the middle finger on the other. The index finger is then positioned over the release button 56 and the palm may be resting on the rounded first end 46.
The injector surface 16 is then placed onto the skin at an injection site with the small spikes 62 pressing onto the skin.
Turning to Figure 3a, before the release button 56 is pressed, the compression spring 30 is in the start, i.e. compressed, state and the stop member 50 is engaged with the device body 12 so as to hold the compression spring 30 and its casing 28 in the start state. The needle 20 is in the retracted state.
Moreover, the first coupling member portion 42a, the tracking portion 44 and the second coupling member portion 42b lie adjacent to the first surface 40a of the rib 36. The second coupling member portion 42b lies adjacent to the first surface 40a of the rib 36 and tracks around the curved rib end 37 to join with the compression spring casing 28.
When injection is to be made, the user presses the release button 56 with the index finger. Pressing the release button 56 pushes the stop member 50 towards the compression spring casing 28 and releases the stop member 50 from the device body 12. Such release means that the compression spring 30 is free to start expanding from the start (i.e. compressed) state to the end (i.e. relaxed) state.
As the compression spring 30 begins to extend, it pushes the casing 28 which slides, in a linear fashion, away from the injector surface 16 of the device body 12. In doing so, the second coupling member portion 42b is pulled by the casing 28 and tracks along the first surface 40a, around the curved rib end 37 and along the second surface 40b of the rib 36 until the tracking portion 44 has tracked along the first surface 40a of the rib 36 to the curved rib end 37.
In doing so, the second coupling member portion 42b pulls the first coupling member portion 42a such that the first coupling member portion 42a tracks along the first surface 40a of the rib 36. In turn, the first coupling member portion 42a pulls the needle hub 22 so that it slides towards the injector surface 16 of the device body 12 until the needle stick 24 exits the opening 18 in the injector surface 16. The needle 20 is now in the injected position, as shown in Figure 3b and penetrates the skin of the patient.
With the needle 20 in the injected position and the tracking portion 44 at the curved rib end 37, the compression spring 30 has reached the intermediate state (i.e. it is partially extended).
As the compression spring 30 continues to extend, the tracking portion 44 passes over the curved rib end 37 which causes the first coupling member portion 42a to cross over the bridging, i.e. top, surface 40c of the rib 36. In other words, the rib 36 is allowed to penetrate through the space beneath the first coupling member portion 42a because the second coupling member portion 42b has now tracked fully around the curved rib end 37 and is now on the second surface 40b of the rib 36.
As shown in Figures 3c and 3d, the compression spring 30 continues to extend from the intermediate state towards the end state and in doing so continues to push the casing 28 away from the injector surface 16. The casing 28 therefore continues to pull the second coupling member portion 42b which now tracks along the second surface 40b of the rib 36. The tracking portion 44 also tracks along the second surface 40b of the rib 36 which pulls the first coupling member portion 42a which slides along the bridging surface 40c of the rib 36.
In turn, the first coupling member portion 42a pulls the needle hub 22 but this time away from the injector surface 16 so as to retract the needle stick 24 back into the device body 12 until the needle stick 24 is fully retracted. The compression spring 30 stops extending such that it is in its relaxed (i.e. end) state and the needle 20 is in the retracted position.
The injector device 10 has therefore penetrated the skin of the patient with a needle 20 and thereafter safely retracted the needle 20 back into the device 10 upon a single actuation, i.e. a single press of the release button 56.
The needle 20 may be configured to deliver a drug to the patient and the drug may be a solid dose drug, e.g. a pellet.
Moreover, the injector device 10 may be a single-use device such that after the 5 compression spring 30 has deformed from the start state to the end state, the device 10 is disposed. Alternatively, there may be a mechanism (not shown) which allows the compression spring to be re-compressed and the needle 20 or needle stick 24 to be replaced, such that the device 10 can be reused.
