DESCRIPTION OF THE EMBODIMENTS
FIG. 1 is a partial schematic view illustrating a glucose test device according to an embodiment of the invention. FIG. 2 is an exploded schematic view illustrating a carrying unit of FIG. 1. FIG. 3 is a schematic view illustrating the glucose test device of FIG. 1 pushing a lancet and a strip out of the carrying unit, wherein for the description clarity, housing 1100 and first body 1212 are illustrated with dashed lines. Referring to FIG. 1 and FIG. 2, in the present embodiment, a glucose test device 1000 includes a housing 1100, a carrying unit 1200, a first push rod 1300, and a second push rod 1400, wherein the housing 1100 may be fabricated with plastic, acrylic, metal, carbon fiber, composite material or other suitable material.
The carrying unit 1200 is detachably assembled in the housing 1100 and includes a first cartridge 1210, a plurality of lancets 1220, a second cartridge 1230 and a plurality of strips 1240. The first cartridge 1210 has a plurality of first perforated grooves 1211, and the lancets 1220 are slidably disposed in the first perforated grooves 1211 respectively. The second cartridge 1230 is adjacent to the first cartridge 1210, wherein the second cartridge 1230 has a plurality of second perforated grooves 1231, and the strips 1240 are slidably disposed in the second perforated grooves 1231 respectively. Herein, the first cartridge 1210 and the second cartridge 1230 are substantially appeared to be semicylindrical in shapes and are adapted to assemble with each other to constitute a main cartridge body 1201. The main cartridge body 1201 constituted by assembling the first cartridge 1210 and the second cartridge 1230 is substantially appeared to be cylindrical in shape and is pivoted in the housing 1100 along a main axis AX.
On the other hand, an amount of the second perforated grooves 1231 and an amount of the first perforated grooves 1211 are equal, wherein the first perforated grooves 1211 surround the main axis AX and are equidistantly arranged on the first cartridge 1210, and the second perforated grooves 1231 surround the main axis AX and are equidistantly arranged on the second cartridge 1230. In the present embodiment, the first perforated grooves 1211, for example, are radially arranged on the main cartridge body 1201 along a counter-clockwise direction R2, and the second perforated grooves 1231, for example, are lined-up after the first perforated groove 1211 with a line-up order being the last, and are radially arranged on the main cartridge body 1201 along the counter-clockwise direction R2 until the second perforated groove 1231 with a line-up order being the last is adjacent to the first perforated groove 1211 with a line-up order being the first. In view of the above design principles, in an embodiment (not shown), the first perforated grooves 1211 and the second perforated grooves 1231 may also be radially arranged on the main cartridge body 1201 along a clockwise direction R1, and the invention is not limited thereto.
In the present embodiment, the first push rod 1300 as corresponding to the first cartridge 1210 is movably disposed in the housing 1100, and second push rod 1400 as corresponding to the second cartridge 1230 is movably disposed in the housing 1100, wherein the first push rod 1300 and the second push rod 1400 are parallel to each other and respectively located at opposite corners of the main cartridge body 1201. Specifically, a cross-sectional profile of the first push rod 1300 is identical to a cross-sectional profile of each of the first perforated grooves 1211, and a cross-sectional profile of the second push rod 1400 is identical to a portion of the cross-sectional profile of each of the second perforated grooves 1231. Therefore, in a subsequent process where the first push rod 1300 pushes any one of the lancets 1220 from its corresponding first perforated groove 1211 to the outside of the first cartridge 1210, the first push rod 1300 may smoothly move into the said first perforated groove 1211 to push out the said lancet 1220. And, in a subsequent process where the second push rod 1400 pushes any one of the strips 1240 from its corresponding second perforated groove 1231 to the outside of the second cartridge 1230, second push rod 1400 may smoothly move into the said second perforated groove 1231 to push out the said strip 1240.
On the other hand, the first cartridge 1210 may include a first body 1212, a first cover 1213, a second cover 1214, a carrier 1215, and an elastic element 1216. The second cartridge 1230 includes a second body 1232 and two film layers 1233 and 1234. The first body 1212 has a plurality of slots 1212a, and the second body 1232 has a plurality of hooks 1232a disposed corresponding to the slots 1212a. Therefore, in a processing of assembling the first cartridge 1210 with the second cartridge 1230, the first body 1212 may be fixed to the second body 1232 by engaging the hooks 1232a into the slots 1212a. 
Specifically, the first perforated grooves 1211 are disposed at the first body 1212, and the second perforated grooves 1231 are disposed at the second body 1232. The first cover 1213 and the second cover 1214 are respectively disposed at two opposite sides of the first body 1212, and the first cover 1213 and the second cover 1214 respectively have a plurality of through holes 1213a and 1214a disposed corresponding to the first perforated grooves 1211. The film layers 1233 and 1234 are respectively disposed at two opposite sides of the second body 1232 and cover the second perforated grooves 1231, wherein the film layers 1233 and 1234 are fabricated with aluminum foil, copper foil or other suitable material, and are configured to prevent the strips 1240 from easily falling out of the second cartridge 1230 from the second perforated grooves 1231. In addition, the carrier 1215 is movably disposed in the first body 1212, wherein the elastic element 1216, for example, is sleeved on a pillar portion 1215a of the carrier 1215 and abuts between the carrier 1215 and the first body 1212. Besides, a holder portion 1221 of each of the lancets 1220 leans against the carrier 1215, and a needle portion 1222 connected to the holder portion 1221 is located in the corresponding first perforated groove 1211. More specifically, the holder portion 1221 of each of the lancets 1220 has a protruding portion 1221a, and each protruding portion 1221a may respectively be positioned in a plurality of notches 1215b of the carrier 1215, so that each of the lancets 1220 may respectively be abutting against the carrier 1215.
Referring to FIGS. 1 through 3, in the present embodiment, when the main cartridge body 1201 rotates in relative to the housing 1100 along the main axis AX (e.g., rotates along the clockwise direction R1) to align any one of the first perforated grooves 1211 with the first push rod 1300 and any one of the second perforated grooves 1231 with the second push rod 1400, the first push rod 1300 may move into the said first perforated groove 1211 towards a firing direction D parallel to the main axis AX, and the holder portion 1221 of the lancet 1220 in the said first perforated groove 1211 is pushed by the first push rod 1300, thereby causing the needle portion 1222 of the lancet 1220 to move out of the first cartridge 1210. Since the holder portion 1221 of each of the lancets 1220 is leaned against the carrier 1215, in the above mentioned process where the first push rod 1300 pushes the needle portion 1222 of the said lancet 1220 out of the first cartridge 1210, the holder portion 1221 of the said lancet 1220 may push the carrier 1215 to move towards the firing direction D by using structural interferences with the carrier 1215, so that the elastic element 1216 is compressed. Now, the holder portions 1221 of the rest of the lancets 1220 not being pushed by the first push rod 1300 are separated from the carrier 1215 and are maintained at their original positions in the first body 1212.
The first push rod 1300, before moving into one of the first perforated grooves 1211 towards the firing direction D, must firstly pass through a through hole 1213a corresponded to the said first perforated groove 1211, wherein the first push rod 1300 matches an opening profile of the through holes 1213a, so that the first push rod 1300 may smoothly pass through the through hole 1213a and move into the said first perforated groove 1211, and thereby pushes the lancet 1220 in the said first perforated groove 1211, so that the needle portion 1222 of the lancet 1220 passes through the corresponding through hole 1214a and moves out of the first cartridge 1210. Specifically, the first cartridge 1210 further includes a buffer layer 1217, wherein the buffer layer 1217 is disposed between the second cover 1214 and the first body 1212 for separating the through holes 1214a on the second cover 1214 from the first perforated grooves 1211. Therefore, when the lancet 1220 is pushed by the first push rod 1300 to move towards the firing direction D, the needle portion 1222 of the lancet 1220 may firstly pass through the buffer layer 1217 and then pass through the corresponding through hole 1214a so as to sample a user's blood.
In general, a blood sample is usually obtained by using the needle portion 1222 to puncture finger pulp of the user. Under the condition that the holder portions 1221 of other lancets 1220 are separated from the carrier 1215, the needle portions 1222 of the other lancets 1220 may be blocked by the buffer layer 1217, and thereby would not easily move out of the first cartridge 1210 from each of the corresponding through holes 1214a. For example, the buffer layer 1217 may be a sponge containing alcohol or other disinfection substances, and thus a purpose of sterilizing the needle portion 1222 of the lancet 1220 may be achieved while the needle portion 1222 passes through the buffer layer 1217, thereby lowering the chances of having bacterial infection when the user uses the needle portion 1222 to sample the blood.
On the other hand, the second push rod 1400 may move into one of the second perforated grooves 1231 towards the firing direction D, and the strip 1240 in the said second perforated groove 1231 is pushed out of the second cartridge 1230 by the second push rod 1400. Specifically, the second push rod 1400 must firstly pass through the film layer 1233 before move into the said second perforated groove 1231, so as to push the strip 1240 in the said second perforated groove 1231 towards the firing direction D. The strip 1240 as being pushed by the second push rod 1400 perforates the film layer 1234 in order to move out of the second cartridge 1230. Now, the blood sample obtained through using the lancet 1220 may drop on the strip 1240, and the strip 1240 containing the user's blood may further be tested for the user's glucose level through using a test element (not shown) in the glucose test device 1000, so as to achieve the purpose of timely monitoring the glucose level. In the above descriptions, the line-up order of the said first perforated groove 1211 on the first cartridge 1210 matches the line-up order of the said second perforated groove 1231 on the second cartridge 1230; and for the purpose of description herein, the line-up orders are, for example, the first of the first perforated grooves 1211 and the first of the second perforated grooves 1231, respectively.
After sampling of the blood, an elastic restoring force of the elastic element 1216 may drive the carrier 1215 to move towards a direction opposite to the firing direction D so as to return back to an initial position as shown in FIG. 1. At the same time, by using structure interferences between the carrier 1215 and the holder portion 1221 of the lancet 1220, when the carrier 1215 is driven by the elastic restoring force of the elastic element 1216 to move towards the direction opposite to the firing direction D, the lancet 1220 may be recover back into the first cartridge 1210, thereby preventing the used lancet 1220 from random disposal and causing environmental health distress. Now, the carrier 1215 as being returned back to the initial position may abut against the holder portion 1221 of each of the lancets 1220 so as to facilitate the subsequent use. On the other hand, the strip 1240 that containing the user's blood may be pulled back into the second cartridge 1230 by the second push rod 1400, or be recovered to a recovery tank (not shown) in the housing 1100, so as to prevent the used strip 1240 from random disposal and causing environmental health distress.
Since the carrying unit 1200 merely uses a single elastic element 1216 to recover the lancets 1220, which are being pushed out at different locations, back into the first body 1212, such that several lancets 1220 are sharing the same elastic element 1216, it does not require to individually install each of the lancets 1220 with an elastic element for recovering the lancet 1220 back into the first body 1212, thereby providing better competitiveness in the overall structure design and the cost consideration.
In view of the above, when the user is to perform the glucose level test again, the user may enable the main cartridge body 1201 to rotate in relative to the housing 1100 along the main axis AX (i.e., rotate towards the clockwise direction R1) to align the first push rod 1300 with the next first perforated groove 1211 in line and align the second push rod 1400 with the next second perforated grooves 1231 in line; namely, the first perforated groove 1211 with a line-up order being the second, and the second perforated groove 1231 with a line-up order being the second. The first push rod 1300 may move into the first perforated groove 1211 with a line-up order being the second towards the firing direction D so as to push the needle portion 1222 of the lancet 1220 out of the first cartridge 1210, and the second push rod 1400 may move into the second perforated groove 1231 with a line-up order being the second towards the firing direction D to push the strip 1240 out of the second cartridge 1230, so as to perform the blood sampling action, wherein the specific operational means of each components may be referred back to the descriptions provided in the above, and will not be repeated herein.
In the aforementioned embodiment, since the first perforated grooves 1211 and the second perforated grooves 1231 are, for example, radially arranged on the main cartridge body 1201 along the counter-clockwise direction R2, the main cartridge body 1201 has to rotate in relative to the housing 1100 along the clockwise direction R1 so as to achieve the purpose of automatically replacing the lancets 1220 and the strips 1240. In an embodiment (not shown), when the first perforated grooves 1211 and the second perforated grooves 1231 are, for example, radially arranged on the main cartridge body 1201 along the clockwise direction R1, the main cartridge body 1201 thus has to rotate in relative to the housing 1100 along the counter-clockwise direction R2 so as to achieve the purpose of replacing the lancets 1220 and the strips 1240.
In addition, since the carrying unit 1200 is detachably disposed in the housing 1100 of the glucose test device 1000, when the lancets 1220 in the first cartridge 1210 and the strips 1240 in the second cartridge 1230 are all being used, the user may detach the old carrying unit 1200 and replace a whole new carrying unit 1200 into the housing 1100 of the glucose test device 1000 for continue usage.
FIG. 4 is a partial schematic view illustrating a glucose test device according to another embodiment of the invention. FIG. 5 is a schematic view illustrating the glucose test device of FIG. 4 pushing a lancet and a strip out of a carrying unit. Referring to FIG. 4 and FIG. 5, different from the glucose test device 1000 of the previous embodiment, in a glucose test device 1000A of the present embodiment, a carrying unit 1200A further includes at least one third cartridge 1250 (illustrated as one in FIG. 4) and a plurality of supplementary elements 1260. The third cartridge 1250 has a plurality of third perforated grooves 1251, and the supplementary elements 1260 (e.g., insulin injection needles) are slidably disposed in the third perforated grooves 1251 respectively, wherein a first cartridge 1210a, a second cartridge 1230a and a third cartridge 1250 are assembled with each other to constitute a main cartridge body 1201a, and the main cartridge body 1201a is pivoted in the housing 1100a along the main axis AX. Component compositions in the first cartridge 1210a and the second cartridge 1230a are the same as in the first cartridge 1210 and the second cartridge 1230, and will not be repeated herein.
On the other hand, the glucose test device 1000A further includes at least one third push rod 1500 (illustrated as one in FIG. 4) parallel to the first push rod 1300a, wherein the third push rod 1500 as corresponding to the third cartridge 1250 is movably disposed in the housing 1100a. Specifically, a distance between the first push rod 1300a and the second push rod 1400a, a distance between the second push rod 1400a and the third push rod 1500 and a distance between the third push rod 1500 and the first push rod 1300a are equal to each other.
The third perforated grooves 1251 surround the main axis AX and are equidistantly arranged on the third cartridge 1250, and an amount of the first perforated grooves 1211 (not shown) in the first cartridge 1210a, an amount of the second perforated grooves 1231 (not shown) in the second cartridge 1230a and an amount of the third perforated grooves 1251 are equal. In the present embodiment, the third perforated grooves 1251, for example, are lined-up after the second perforated groove 1231 wither a line-up order being the last, and are radially arranged on the main cartridge body 1201a along the counter-clockwise direction R2 until the third perforated groove 1251 with a line-up order being the last is adjacent to the first perforated groove 1211 with a line-up order being the first. Namely, the third cartridge 1250, for example, is connected between the first cartridge 1210a and the second cartridge 1230a. In view of the above design principles, in an embodiment (not shown), the first perforated grooves 1211, the second perforated grooves 1231 and the third perforated grooves 1251 may also be radially arranged on the main cartridge body 1201a along a clockwise direction R1, and the invention is not limited thereto.
On the other hand, a cross-sectional profile of the third push rod 1500 is identical to a cross-sectional profile of each of the third perforated grooves 1251, and thus in a subsequent process where the third push rod 1500 pushes any one of the supplementary elements 1260 from its corresponding third perforated groove 1251 to the outside of the third cartridge 1250, the third push rod 1500 may smoothly move into the said third perforated groove 1251 to push out the said supplementary element 1260.
When the main cartridge body 1201a rotates in relative to the housing 1100a along the main axis AX (e.g., rotates along the clockwise direction R1) to align any one of the first perforated grooves 1211 with the first push rod 1300a, any one of the second perforated grooves 1231 with the second push rod 1400a and any one of the third perforated grooves 1251 with the third push rod 1500, the third push rod 1500 may also move into the third perforated grooves 1251 towards the firing direction D, and the supplementary element 1260 in the said third perforated groove 1251 is pushed out of the third cartridge 1250 by the third push rod 1500, wherein a line-up order of said first perforated groove 1211 on the first cartridge 1210, and a line-up order of the said second perforated groove 1231 on the second cartridge 1230 and a line-up order of the said third perforated groove 1251 on the third cartridge 1250 are matched with each other. For the purpose of description herein, the line-up orders are, for example, the first of the first perforated grooves 1211, the first of the second perforated grooves 1231 and the first of the third perforated grooves 1251. Wherein, specific operational means between the first push rod 1300a and the lancets 1220 and between the second push rod 1400a and the strips 1240 may be referred back to the above descriptions, and will not be repeated herein.
In view of the above design principles, in an embodiment (not shown), the first perforated grooves 1211, the second perforated grooves 1231 and the third perforated grooves 1251 may also be radially arranged on the main cartridge body 1201a along the clockwise direction R1, and the invention is not limited thereto. Then, the main cartridge body 1201 a has to rotate in relative to the housing 1100a along the counter-clockwise direction R2 so as to achieve the purpose of replacing the lancets 1220, the strips 1240 and the supplementary elements 1260.
In other words, the glucose test device 1000A not only can achieve the purpose of automatically replacing the lancets 1220 and the strips 1240 by using the carrying unit 1200a, but also can push the supplementary elements 1260 out of the third cartridge 1250 by using the third push rod 1500, so as to inject insulin to lower the user's glucose level when the user's glucose level being too high. On the other hand, in an embodiment (not shown), depending on the actual needs, the glucose test device 1000A may be configured with more than two third cartridges 1250, and other needles, strips or medicines in need may also be installed in the corresponding third perforated grooves 1251 so as to fulfil the user's choices, and thereby enhances a flexibility of application.
FIG. 6 is a partial schematic view illustrating a glucose test device according to yet another embodiment of the invention. FIG. 7 is a schematic view illustrating the glucose test device of FIG. 6 pushing a lancet and a strip out of a carrying unit. Referring to FIG. 6 and FIG. 7, different from the glucose test device 1000 of the previous embodiment, in a glucose test device 1000B of the present embodiment, a carrying unit 1200b includes a first cartridge 1210b and a second cartridge 1230b disposed parallel to each other, wherein the first cartridge 1210b is pivoted in the housing 1100b along a first axis AX1, and the second cartridge 1230b is pivoted in the housing 1100b along a second axis AX2 parallel to the first axis AX1.
On the other hand, the first perforated grooves 1211 surround the first axis AX1 and are equidistantly arranged on the first cartridge 1210b, the second perforated grooves 1231 surround the second axis AX2 and are equidistantly arranged on the second cartridge 1230b, and an amount of the first perforated grooves 1211 and an amount of the second perforated grooves 1231 are equal. The first push rod 1300b and the second push rod 1400b, for example, are respectively located at two opposite sides of the carrying unit 1200b. When the first cartridge 1210b rotates in relative to the housing 1100b along the first axis AX1 to align any one of the first perforated grooves 1211 with the first push rod 1300b, the first push rod 1300b moves into the said first perforated groove 1211 towards a firing direction D1 parallel to the first axis AX1, and the needle portion 1222 of the lancet 1220 in the said first perforated groove 1211 is pushed out of the first cartridge 1210b by the first push rod 1300b, so as to sample the user's blood. Herein, for the purpose of description, the first cartridge 1210b is, for example, illustrated as rotating in relative to the housing 1100b along the clockwise direction R1, but the invention is not limited thereto.
When the second cartridge 1230b rotates in relative to the housing 1100b along the second axis AX2 to align any one of the second perforated grooves 1231 with the second push rod 1400b, the second push rod 1400b moves into the said second perforated groove 1231 towards the firing direction D1, and the strip 1240 in the said second perforated groove 1231 is pushed out of the second cartridge 1230b by the second push rod 1400b. Then, the blood sample obtained through the lancet 1220 may drop on the strip 1240 for the subsequent testing of the user's glucose level. Herein, for the purpose of description, the second cartridge 1230b is, for example, illustrated as rotating in relative to the housing 1100b along the clockwise direction R1, but the invention is not limited thereto.
In summary, the carrying unit of the invention at least include the first cartridge and the second cartridge, wherein the first cartridge is configured with a plurality of lancets therein, and the second cartridge is configured with a plurality of strips corresponding to the amount of the lancets. In addition, the first cartridge and the second cartridge may be parallelly disposed in the housing, or may be disposed in the housing after assembled with each other to constitute the main cartridge body. Therefore, each time when performing the glucose test, the user may use the carrying unit to automatically replace lancets and strips for performing the sampling and testing of blood, and thus avoids a process of repeatedly detaching the lancets and the strips, thereby improving a convenience of usage, and further preventing the lancets and the strips from being reused and causing bacterial infection or blood-borne infection.
On the other hand, since the carrying unit is detachably disposed in the housing of the glucose test device, when the lancets in the first cartridge and the strips in the second cartridge are all being used, the user may detach the old carrying unit and replace a whole new carrying unit into the housing of the glucose test device for subsequent use. Moreover, depending on the actual needs, the glucose test device may be configured with more than two third cartridges, and other needles, strips or medicines in need may also be installed in the corresponding third perforated grooves in the third cartridge so as to fulfil the user's choices, and thereby enhances the flexibility of application.
