The specific embodiment
According to the preferred embodiment of the present invention micro neddle roller assembly is described with reference to the accompanying drawings in more detail.
The first embodiment
Fig. 1 is the axonometric chart according to the micro neddle roller assembly of first embodiment of the invention, and Fig. 2 is the exploded perspective view according to the micro neddle roller assembly of first embodiment of the invention.
See figures.1.and.2, micro neddle roller assembly 100 (below be called " neddle roller assembly ") comprises roller head 120 and handle component 110.
Roller head 120 comprises outside hollow barrel-type member 121 (below be called " external member ") and places the inner hollow member 122 of external member 121 (below be called " internals ").Internals 122 is fixed thereon and a plurality of support members 123 of radially extension are supported to external member 121.The quantity of support member 123 and the length of each support member are not limit.Yet preferably the length of each support member 123 is identical with external member 121, thus this external member distortion when preventing externally that member 121 is stressed.
External member 121 and internals 122 coaxial arrangement, the shape of internals is not limited to given shape.The reception space 124 of internals 122 is as the space that receives the particular elements that consists of following handle component 110.
Externally form a plurality of microneedle 125 (below be called " pin ") on the outer surface of member 121.Preferably, the external member 121 of roller head 120 and pin 125 are integrally formed and made by polymer resin each other, described polymer resin for example comprises the thermosetting resin of epoxy resin, phenolic resins, polyurethane resin, perhaps comprises the thermoplastic resin of PC (Merlon), PEI (Polyetherimide), PMMA (polymethyl methacrylate), POM (polyacetals), PLA (polylactic acid), PSU (polysulfones) etc.
Here, preferably use biodegradable polymers as polymer resin, for example PLA (polylactic acid), PLGA (polylactic acid alkyl acetate multipolymer).Because above material, when pin 125 was stayed in the skin, the pin of being made by above-mentioned material can not damage human body and can decompose at short notice.
Each pin 125 stretches out certain altitude from the outer surface of external member 121.The height of pin 125 can change according to the purposes of micro neddle roller assembly 100.For example, form the passage that arrives skin corium if pin 125 passes epidermis, then the height of pin 125 from 200 μ m in the scope of 750 μ m.Usually, the height of pin 125 determines that from 20 μ m to 2, in the scope of 000 μ m, yet the height of necessary hour hands can exceed above scope.
On the other hand, pin 125 can be partitioned into to arrange with rule and put on the outer surface of member 121 externally.Because above structure can obtain uniform passage and distribute on the specific region of skin.Yet, in order to form a large amount of passages in the specific region of skin by pin 125, expectation be to make the distance between the row who consists of pin 125 on the outer surface of external member 121 narrower in possible limit.
In addition, Fig. 2 illustrates each pin 125 and has cone shape.Yet the shape of pin is not limited to this.
On the other hand, different from roller head shown in Figure 3, roller can only utilize one therein the heart Cylinder shape constructional element that partly forms the tubular space consist of.Yet the roller head volume that inevitably has above structure is larger, so previous materials is subject to very large heat affecting in the forming process of making the roller head.
Consider above-mentioned situation, comprise internals 122, external member 121 and be connected a plurality of support members 123 of two members according to the roller head 120 of this embodiment, therefore the whole volume of roller head reduces greatly, thereby can obviously reduce the distortion that heat causes in the forming process.
Specifically, in the micro neddle roller assembly according to present embodiment, the tubular external member, be formed on that a plurality of pins on the outer surface of tubular external member and internals are made by polymer resin and integrally formed each other, the roller head can form by only carrying out shot forming process.
On the other hand, handle component 110 comprises handle 111 and the first and second linking arms 112 and 113 that extend to both sides from an end of handle.The first and second linking arms 112 and 113 free end are corresponding to the two side ends of the internals 122 of roller head 120.It is outstanding at the inner surface of the free end of the first and second linking arms 112 and 113 respectively to have the stud bump 112A of certain-length and 113A.
In the both side ends in the reception space 124 of the internals 122 that inserts roller head 120 by the stud bump 112A that will form at the inner surface of the free end of the first and second linking arms 112 and 113 and 113A, finished the assembling of handle component 110 and roller head 120.
The diameter of each projection 112A and 113A is less than the diameter in the reception space 124 of internals 122, so each projection 112A and 113A can rotate in the receiving member of internals 122.
On the other hand, hinder projection 112A and 113A after receiving the space by from receiving space 124 taking-ups in order easily to insert with the reception space 124 of projection 112A and 113A insert member 122 and in projection, preferably the first and second linking arms 112 of handle component 110 and 113 are made by having elastic material.
The function according to the neddle roller assembly 100 of this embodiment of structure is as mentioned above described with reference to the accompanying drawings.
As mentioned above, will insert in the both side ends in reception space 124 of internals 122 of roller head 120, with assembled handle member 110 and roller head 120 at the first and second linking arms 112 of handle component 110 and the 113 projection 112A that form and 113A.
Then, user is caught the handle 111 of handle component 110 and the external member 121 of roller head 120 is placed on the skin.At this moment, the percutaneous medicine is coated on the skin.
Under this state, in case user application of force on handle 111, roller head 120 is just around being received in projection 112A and the 113A rotation and mobile at skin that receives in the space 124.
Because the rotation of roller head 120 and mobile at skin, the pin 125 that is formed on the external member 121 penetrates a part of epidermis or the transport path (passage) of whole epidermis to be formed for the percutaneous medicine that consists of skin.In above process, be coated in the passage transdermal that the percutaneous medicine on the skin forms by pin 125.
On the other hand, as mentioned above, if receive therein and the reception space 124 that rotates has cylindrical form for the projection 112A that form at the first and second linking arms 112 and 113 and 113A, then the internals 122 of roller head 120 needn't form cylindrical form.In addition, form along the whole length of internals 122 although above description represents to receive space 124, this space can be formed in each of two ends of internals 122.
The second embodiment
Fig. 3 and Fig. 4 are according to the axonometric chart of the micro neddle roller assembly of second embodiment of the invention and exploded perspective view, show formation according to the structure of each member of the micro neddle roller assembly of second embodiment of the invention.
With reference to Fig. 3 and Fig. 4, micro neddle roller assembly 200 (below be called " neddle roller assembly ") also comprises roller head 220 and handle component 210.
Handle component 210 comprises handle 211 and the first and second linking arms 212 and 213 that extend to both sides from an end of handle.The first and second linking arms 212 and 213 free end are corresponding to the two side ends of the internals 222 of roller head 220.Have the stud bump 212A of certain-length and 213A respectively outstanding formation of inner surface of the free end of the first and second linking arms 212 and 213.
The 26S Proteasome Structure and Function of each element of formation handle component 210 is identical with the 26S Proteasome Structure and Function of each element that consists of handle component 110, therefore omits description of them.
Comprise outside hollow barrel-type member 221 (below be called " external member ") and place the inner hollow member 222 (below be called " internals ") of external member 221 according to the roller head 220 in the neddle roller assembly 200 of present embodiment.Internals 222 is fixed thereon and a plurality of support members 223 of radially extension are supported to external member 221.
External member in external member 221 in the present embodiment and the structure of internals 222 and relation and the first embodiment is identical with relation with the structure of internals, so omits description of them.
In addition, at the outer surface of the external member 221 of roller head 220 a plurality of pin pieces 230 are installed.Specifically describe the structure of roller head 200 and pin piece referring to Fig. 4 and Fig. 5.
As shown in Figure 4, roller head 220 comprises outside hollow barrel-type member 221 and inner hollow member 222, externally forms a plurality of groove 221-1 with certain-length on the outer surface of member 121.The both ends open of each groove 221-1, the width on each groove top is less than the width of bottom.
Fig. 5 is the axonometric chart that is installed to the pin piece 230 on the roller head 220.
Pin piece 230 shown in Figure 5 is installed on the outside hollow member 221 of constructing as mentioned above.
Pin piece 230 is received among each groove 221-1 that is formed on tubular external member 221 outer surfaces.Thereby pin piece 230 has identical overall cross-sectional shape with groove 221-1 on being formed at tubular external member 221.That is to say that the lower width W2 of pin piece 230 is greater than upper width W1, so the pin piece 230 of groove 221-1 can not be along the radial separation of outside hollow member 221.On the other hand, the height of each pin piece 230 is identical with the degree of depth of each groove 221-1, and arranges a plurality of pins 225 at the upper surface of pin piece 230.
Pin piece 230 and pin 225 are can be each other integrally formed and made by the polymer resin such as epoxy resin, phenolic resins, polyurethane resin or thermoplastic resin, and described thermoplastic resin is such as being PC (Merlon), PEI (Polyetherimide), PMMA (polymethyl methacrylate), POM (polyacetals), PLA (polylactic acid), PSU (polysulfones) etc.
Here, preferably use biodegradable polymer as polymer resin, for example PLA (polylactic acid), PLGA (polylactic acid alkyl acetate multipolymer).Because above material, if the pin 225 that separates with pin piece 230 is stayed in the skin, the pin of then being made by above-mentioned material can not damage human body and can decompose at short notice.
Each pin 225 stretches out certain altitude from the outer surface of pin piece 230.The height of pin 225 can change according to the purposes of micro neddle roller assembly 200.For example, form the passage that arrives skin corium if pin 225 passes epidermis, then the height of pin 225 from 200 μ m in the scope of 750 μ m.Usually, the height of pin 225 determines that from 20 μ m to 2, in the scope of 000 μ m, yet the height of necessary hour hands can exceed above scope.
Here, pin 225 can be arranged on the pin piece 230 with regular interval.Because above structure can obtain uniform passage and distribute in the specific region of skin.Yet, in order to form a large amount of passages in the specific region of skin by pin 225, expectation be to make on the pin piece 230 distance between the pin 225 narrower.In addition, Fig. 5 represents that each pin 225 has cone shape.Yet the shape of pin is not limited to this.
As shown in Figure 4, on the other hand, side cover 240 and 250 is installed to the both sides of external member 221, is used for preventing that pin piece 230 is along the axial separation of external member 221.Side cover 240 is identical with the diameter of external member 221 with 250 diameter.
In case side cover 240 and 250 is fixed to the both sides of external member 221, just expose by the opening 241 and 251 that is formed on side cover 240 and 250 middle bodies two ends of internals 224, and two opening sides of each groove 221-1 correspond respectively to side cover 240 and 250.Under this state, by side cover 240 or 250 the pin piece 230 that is received among the groove 221-1 can not be separated with groove.
Assembling process and function according to the neddle roller assembly 200 of this embodiment are described with reference to the accompanying drawings.
At first, by promoting pin piece 230 with among the opening slip insertion groove 221-1 of each pin piece 230 by corresponding groove 221-1, then in all pin piece insertion grooves, afterwards side cover 240 and 250 is respectively fixed to the both side ends of external member 221.
Under this state, be formed in two ends of exposing side cover 240 and 250 in reception space 224 of the internals 222 that projection 212A on first and second linking arms 212 and 213 of Handleset 210 and 213A insert roller head 120, with assembled handle member 210 and roller head 220.
