Definitions
- the invention relates to an applicator for applying a microarray.
- Microarrays have a multiplicity of microneedles, which are usually arranged on a carrier element, such as a patch, a plaster or the like, or are connected to a carrier element. Such microarrays have a high number of microneedles, for example 500-600 needles per cm 2 .
- the needles have a short length, so that when the microneedles are pressed into the skin of a patient, the needles only penetrate into the skin to such an extent that nerves and blood vessels are not touched by needle tips if possible.
- the microneedles have an active ingredient or a medicament.
- the corresponding active ingredient can be applied to a surface of the needle or can be arranged in the needles. It is preferred that the needles be made from a material that dissolves in the patient's skin.
- microarrays in human skin
- the problem with the application of microarrays in human skin is that the insertion of the microneedles into the skin must be reproducible, in particular to ensure reliable drug delivery.
- the insertion of the microneedles must also be independent of the user or patient, since otherwise reproducibility would not be guaranteed.
- the insertion of the microneedles should also be independent of the Skin texture, so that a certain depth of penetration is always ensured.
- the object of the invention is to provide an applicator for applying a microarray, with which the reproducibility of the introduction of the microarray is improved.
- the applicator according to the invention for applying a microarray has a housing in which a stamp is arranged so as to be linearly movable. Furthermore, a holding element is provided for receiving a microarray, in particular connected to the housing or arranged on it. Here, the microarray can be picked up directly or indirectly by the holding element. In particular, a support element, such as a patch or the like, which is connected to the microarray or carries the microarray, can be received by the holding element. Furthermore, the applicator according to the invention has a pressure element for displacing the stamp.
- the microarray held by the holding element can be acted upon by a corresponding displacement of the stamp.
- the pressure element in particular applies a short-term force to the microarray, so that the needles are pressed into the patient's skin.
- the applicator according to the invention has an actuating element for actuating the stamp.
- the actuating element holds the stamp indirectly or directly in an inner or retracted position, ie in a position before the microarray is pressed into the patient's skin.
- the actuating element can either act directly on the stamp, be positively connected to it, for example, or also on the pressure. act on the element.
- a release in particular by manual actuation of the actuation element, so that the stamp is released for displacement.
- the microarray is pressed into the skin correspondingly quickly by the stamp by a particularly sudden or sudden movement of the stamp.
- a particularly clearly defined force acts on the microarray, so that a good reproducibility of the pressing of the microarray into the patient's skin is achieved.
- the holding element has a receiving surface for arranging a carrier element connected to the microarray, such as a patch, a plaster or the like.
- the carrier element can, for example, be arranged on the receiving surface by gluing.
- the receiving surface which is in particular flat, is at least partially ring-shaped and, particularly preferably, fully ring-shaped.
- the housing of the applicator preferably has an outlet opening through which the stamp can exit.
- the stamp is pushed out by the pressure element through the outlet opening or acts on the microarray in the region of the outlet opening.
- the stamp and / or the outlet opening for the stamp is at least partially, in particular completely, surrounded by the receiving surface.
- the stamp is particularly in its outer position, i.e. H. in the position in which the stamp of the microarray is or has been pressed into the skin, surrounded by the receiving surface.
- the pressure element is biased and / or compressed in the inner position of the stamp.
- the pressure element is a spring, such as a spiral spring, a pneumatic chamber and / or the hydraulic chamber, or combinations.
- the pressure element can also have, for example, an elastic element, such as a compressible plastic, which acts on the stamp.
- the pressure element is preferably arranged on a rear side of the stamp opposite the outlet opening.
- the pressure element can, for example, also be arranged laterally and at other points and interact with the stamp in such a way that when the stamp is actuated or triggered, the stamp moves linearly in the direction of the microarray in order to press it into the patient's skin.
- it is preferred that the pressure element is arranged on the back of the stamp.
- the actuating element interacts directly with the stamp.
- An actuating element that can be actuated manually by a patient, a doctor or the like is particularly preferred here.
- the actuating element for holding the stamp in the inner position is positively connected to the stamp and thus holds the stamp in its lower position.
- the actuating element can also be connected to the pressure element, as a result of which the actuating element expands or relaxes the pressure element, since it causes actuation or linear displacement of the stamp.
- the stamp does not necessarily have to be held in a lower position by the actuating element. This is essentially preferred if the pressure element is held in a controlled position by the stamp itself and the pressure element is not triggered separately.
- the stamp has a recess or an extension which interacts with the actuating element.
- the actuating element or an extension of the actuating element can protrude into the recess.
- the actuating element is loaded out of the recess. moves, so that the stamp is released and can be moved linearly by the printing element.
- the actuating element is displaced and / or rotated in order to release the stamp.
- the actuating element is preferably arranged in a receptacle of the housing. This can be a recess, a slot-shaped opening or the like.
- the housing comprises a fixing element and / or is connected to a fixing element.
- the fixing element is used to fix the applicator on a patient's skin.
- a fixing element for example, a vacuum element could be hen. With this, a vacuum is created, similar to a suction cup, so that the applicator is sucked into the patient's skin.
- the suppression could be generated by pressing the applicator onto the patient's skin.
- the negative pressure can also be generated by the pressure element.
- the pressure element could be designed in such a way that when the stamp is triggered and the microarray is pressed into the skin, a suppressive force is simultaneously generated which sucks the applicator onto the patient's skin.
- the fixing element has an abutment surface, which is designed in particular in particular.
- the contact surface surrounds the receiving surface, which is used to arrange the carrier element for the microarray, at least partially.
- the contact surface in particular corresponding to the receiving surface, is partially ring-shaped and in particular fully ring-shaped.
- an adhesive layer is provided on the contact surface in order to fix the applicator or the fixing element on the patient's skin.
- the contact surface provided with an adhesive layer is preferably provided with a removable or removable protective film or the like.
- the microarray can be held in the pressed-in position by the pressure element. This is possible, for example, by applying a residual force to the pressure element.
- Fig. 1 is a schematic perspective plan view of an embodiment of the applicator and Invention
- Fig. 2 is a schematic sectional view of that shown in Figure 1
- the applicator has a housing 10. In the illustrated embodiment, this is composed of a cover 12, an intermediate element 14 and a base element 16, wherein the intermediate element 14 and the base element 16 can be formed in one piece. In the illustrated embodiment, the cover element 12 is fixed by means of pins or screws 18, it also being possible to fix it by gluing, a snap connection, a screw connection or the like.
- a stamp 20 is arranged within the housing 10. The stamp 20 is formed in the exemplary embodiment shown approximately rotationally symmetrical about a central axis 22.
- the stamp 20 has a stamp element 26 on a front side 24 which, when the applicator is used, points in the direction of the patient's skin.
- the stamp Element 26 has a cross section which corresponds to the dimensions of a microarray 28.
- the microarray 28 can be round or square, for example, or can have another geometric shape.
- a pressure element 34 is arranged on a rear side 32 of the stamp 20 opposite the front side 24 or an outlet opening 30.
- the pressure element 34 is a spiral spring. In the inner position of the plunger 20 shown in FIG. 2, the compression spring 34 is compressed, being supported on an inside of the housing cover 12.
- the base element which is also rotationally symmetrical to the central axis 22 in the exemplary embodiment shown, has a flat underside 36.
- the flat underside 36 on the one hand has an inner annular region 38 which serves as a holding element and which serves as a receiving surface for the patch 40 which carries the microarray 28 or is connected to it.
- the patch 40 can in this case be arranged in particular by gluing to the receiving surface 38.
- the annular receiving surface 38 is surrounded by a likewise annular contact surface 42.
- the contact surface 42 is used for contact with the upper surface of the patient's skin.
- the contact surface 42 is preferably also provided with an adhesive layer which may be covered by a peelable film.
- the underside 36 can also be stepped, so that in particular the receiving surface 38 is formed as a depression in relation to the contact surface 42, so that the patch 40 together with the microarray 28 in particular does not protrude beyond the contact surface 42.
- the applicator has an actuating element 44.
- the actuation supply element 44 is essentially L-shaped in the illustrated embodiment and has an extension 46, via which the actuating element can be actuated by hand.
- the actuating element can move from the position shown in FIG. 2 in the direction of an arrow 48 be moved inside.
- an opening or recess 50 of the actuating element in FIG. 2 is shifted to the right, and an extension 52 of the actuating element 44 is pushed out of a recess 54 provided in the stamp 20 by displacing it in FIG. This results in a release of the stamp 20, which can then be moved linearly downward through the opening 50 in Figure 2.
- the actuating element 44 As soon as the actuating element 44 is pushed inward in the direction of the arrow 48 and the stamp is released, it is immediately moved downward in FIG. 2 in the direction of the microarray 28. This is done by the compressed spring 34. A linear displacement of the stamp 20 results in an especially sudden pressing of the microarray 28 into the patient's skin, not shown.
- the microarray 28 is held in the pressed-in position in the skin by the residual force exerted by the spring 34. Since the applicator in the exemplary embodiment shown is designed as an adhesive surface and has a fixing element 42, the applicator is also held on the patient's skin. By providing a fixing element according to the invention in a preferred embodiment, it is possible to keep the microarray in the pressed-in position in the patient's skin and to prevent the microarray from being squeezed out, in particular due to the elasticity of the skin.
