Description

TECHNICAL FIELD

[0001] The present disclosure relates to a needle cover recovery method, a needle cover insertion and extraction system, and an adjustment device, in particular, a needle cover recovery method, a needle cover insertion and extraction system, and an adjustment device for a syringe. BACKGROUND

[0002] In current automated devices, although a mechanical device (e.g. a robot arm) can be used to grip a syringe to perform the operation of inserting and extracting a needle cover, if the needle of the syringe is tilted after use (e.g. after drawing liquid or injection), the needle cover recovery operation to insert the needle cover back into the syringe can cause the tilted needle to pierce the transparent needle cover, or the needle can leak, causing the solution remaining in the syringe to spill out, which can cause environmental pollution or affect the safety of the syringe operator (e.g. medical staff). If the spilled solution is a toxic liquid, it can also affect the surrounding environment and even public safety. Furthermore, the tilted needle can also cause the needle cover to be placed in a tilted position, resulting in deviation in the clamping of the syringe, or even clamping failure.

[0003] Therefore, it is necessary to provide a novel needle cover recovery method, a needle cover insertion and extraction system, and an adjustment device to improve the above problems. SUMMARY

[0108] Next, the use of the needle cover plugging device 10 in step A5 or step B6 is described. Figure 3A is a step flow chart of the needle cover plugging system of an embodiment of the present application performing the needle cover recovery (hereinafter referred to as covering), and please refer to Figure 4 is a schematic diagram of the needle cover plugging system of an embodiment of the present application performing the covering, wherein the needle cover plugging system comprises a first clamping element 41 and a needle cover plugging device 10 as shown in Figure 1 , the first clamping element 41 is for example but not limited to a mechanical arm, the first clamping element 41 is suitable for fixing a syringe 42, and the syringe 42 has a needle 422, the second clamping element 17 of the needle cover plugging device 10 is suitable for fixing a needle cover 423, and the needle cover 423 has a containing space SS for containing the needle 422 of the syringe 42, the extension direction (Y direction) of the containing space SS of the needle cover 423 is parallel to the extension direction (Y direction) of the needle 422, and the limiting element 12 of the needle cover plugging device 10 is suitable for contacting the needle cover 423 to provide a limiting function for the needle cover 423. First step C1 is performed to make the first clamping element 41 clamp the syringe 42 without the needle cover, wherein the syringe 42 is provided first, the syringe 42 is fixed on the first clamping element 41 and has a needle 422, and then the needle cover 423 is provided, the needle cover 423 can be fixed on the second clamping element 17 in advance and has a containing space SS. Since the used syringe 42 must be covered before being discarded, the first clamping element 41 clamping the syringe 42 without the needle cover can be controlled to move in the +Y direction, and stop at a distance D1 between the upper edge of the barrel 421 of the syringe 42 and the adjusting element 18, at this time the needle 422 is skewed.

[0109] Then, the step C2 is performed, the needle cover plugging device 10 aligns the needle 422 and the first clamping element 41 continuously clamps and moves the syringe 42 without the needle cover so that the needle 422 starts to be inserted into the needle cover 423, please refer to Figure 5 Fig. 6 shows another schematic view of the needle cover plugging system of an embodiment of the present application, the part marked by the dashed frame is enlarged to facilitate the description, wherein, when the first clamping element 41 and the second clamping element 17 are close to each other so that the needle 422 is adjacent to the needle cover 423, the adjusting element 18 is provided to adjust the needle 422 to face the accommodation space SS of the needle cover 423, that is, the first adjusting unit 181 and the second adjusting unit 182 of the adjusting element 18 can be close to each other along the X direction to adjust the needle 422, and the skew needle 422 is aligned, as shown in the enlarged view of the dashed frame of Figure 5 Fig. 7 shows another schematic view of the needle cover plugging system of an embodiment of the present application, more particularly, in a cross section of the needle cover plugging device 10, the second adjusting unit 182 can have a protrusion PP, and the first adjusting unit 181 has a recess RR corresponding to the protrusion PP, therefore, by the close to each other of the first adjusting unit 181 and the second adjusting unit 182, the protrusion PP exerts force on the needle 422 and the corresponding recess RR, so that the skew needle 422 can be adjusted. Then, please refer to Figure 8 Fig. 8 shows another schematic view of the needle cover plugging system of an embodiment of the present application, the first clamping element 41 continues to move upwards along the +Y direction so that the first clamping element 41 and the second clamping element 17 are continuously close to each other, the needle 422 can be adjusted by the adjusting element 18 to face and be inserted into the accommodation space SS, that is, the extending direction (such as the Y direction) of the needle 422 is parallel to and faces the extending direction (such as the Y direction) of the accommodation space SS, at this time, the needle 422 can touch the adjusting element 18 and continuously move, the distance between the upper edge of the barrel 421 and the adjusting element 18 is shortened to D2 (D2 < D1), to ensure that the needle 422 is inserted into the accommodation space SS of the needle cover 423, and when the needle 422 has entered the needle cover 423 (for example, more than 1 / 2 of the length of the needle 422 has entered the accommodation space SS of the needle cover 423, but not limited to this), the adjusting element 18 can move outward along the X direction to leave the needle 422, at this time, the first clamping element 41 can continue to move upwards along the +Y direction to complete the covering action, at this time, the distance between the upper edge of the barrel 421 and the adjusting element 18 is the smallest. In particular, as in the order of time, the above-mentioned covering process can be divided into a first time interval and a second time interval later than the first time interval, in the first time interval, the adjusting element 18 contacts the needle 422, and the needle cover 423 and the needle 422 are partially overlapped and gradually increase the overlapping part, in the second time interval, the needle cover 423 and the needle 422 are completely overlapped, and then the adjusting element 18 can move outward so that the adjusting element 18 and the needle 422 are spaced apart by a distance greater than 0 to be able to leave or not to touch the needle 422.

[0110] Next, step C3 is performed, the second clamping element 17 of the needle cover plugging device 10 is opened outwardly in the X direction to release the needle cover 423, and the first clamping element 41 moves the syringe 42 containing the needle cover 423 in the -Y direction to leave the needle cover plugging device 10. Thus, the use mode of the needle cover plugging device 10 for covering can be understood.

[0111] In addition, it should be noted that the above step C2 for aligning the needle 422 is completed by the adjusting element 18 which is a part of the needle cover plugging device 10, but the present application is not limited thereto, in an embodiment of the present application, a separate adjusting device 61 (shown in Figure 6A and 6B ) can be provided to align the needle 422 of the syringe 42 for covering or to adjust the needle 422 of the syringe 42 to accurately insert into the insertion hole (not shown in the figure) of the container with liquid medicine, or the adjusting device 61 replaces the adjusting element 18 of the needle cover plugging device 10 to align the needle 422 of the syringe 42 for covering.

[0112] Please refer to Figure 6A and 6B which respectively show a side view (Z direction) and a top view (Y direction) of an embodiment of the adjusting device 61, wherein the adjusting device 61 is suitable for adjusting the needle 422 of the syringe 42, and comprises a first adjusting unit 611 and a second adjusting unit 622, wherein the first adjusting unit 611 and the second adjusting unit 622 are located at different heights in the top view direction (Y direction), at least one of the first adjusting unit 611 and the second adjusting unit 622 has an opening 65, and in the top view direction (Y direction), the shape of the opening 65 is triangular. Figure 6B In the embodiment, the first adjusting unit 611 and the second adjusting unit 622 each have a triangular opening 65, accordingly, since the adjusting device 61 adopts the design that the distance W between the first adjusting unit 611 and the second adjusting unit 622 changes from large to small, it can align the needle 422 with different degrees of skew, that is, in the initial state, the syringe 42 is placed in the position so that the needle 422 falls between the first adjusting unit 611 and the second adjusting unit 622 (as shown in Figure 6B ), at this time, the distance W between the first adjusting unit 611 and the second adjusting unit 622 is the smallest, then the second driving unit 16 (shown in Figure 1, in this embodiment, the adjustment device 61 is used to replace the adjustment element 18) to drive the first adjustment unit 611 and the second adjustment unit 612 to move towards each other and to the center, so that the distance W gradually decreases. Since the first adjustment unit 611 and the second adjustment unit 612 have triangular openings 63, when the first adjustment unit 611 and the second adjustment unit 612 move towards each other, in the top view direction (Y direction), the first adjustment unit 611 and the second adjustment unit 612 will partially overlap, and the area of the opening 65 will decrease with the degree of mutual approach of the first adjustment unit 611 and the second adjustment unit 612. Therefore, as the first adjustment unit 611 and the second adjustment unit 612 continue to move towards the center, the needle 422 will also be guided to move towards the center, and finally be positioned or engaged at the tip 651 of the two triangular openings 65, as shown in Figure 6C Another top view of the adjustment device 61 is shown, according to which, after the adjustment device 61 is positioned, the needle 422 can be accurately inserted into the insertion hole (not shown) of the container due to the cross design on the left and right sides.

[0113] In addition, the aforementioned adjustment device 61 can also include a third adjustment unit 613, wherein the first adjustment unit 611, the second adjustment unit 612, and the third adjustment unit 613 can each have a triangular opening 65, and as shown in Figure 6A in the top view direction (Y direction), the second adjustment unit 612 is located between the first adjustment unit 611 and the third adjustment unit 613, according to which the needle 422 can be effectively guided and limited.

[0114] Furthermore, based on the design concept that the distance W between the first adjustment unit 611 and the second adjustment unit 612 decreases when they move towards each other, the shape of one of the first adjustment unit 611 and the second adjustment unit 612 can not be limited to the design of a triangular opening, but can also use a planar design, and at least one corner of the opening of the other of the first adjustment unit 611 and the second adjustment unit 612 has a circular arc shape, as shown in Figure 6D Another embodiment of the adjustment device 61 is shown in a top view (Y direction), wherein the first adjustment unit 611 has a triangular opening 63 and at least one corner 651 of the triangular opening 63 has an arc shape, i.e., the corner 651 of the triangular opening 63 has a circular arc shape, but the second adjustment unit 622 does not have an opening and is a rectangular design, i.e., one side of the second adjustment unit 622 relative to the triangular opening 63 of the first adjustment unit 611 is a straight line shape, according to which the needle 422 can still be effectively guided and / or limited, and the probability of affecting the function of the needle 422 of the adjustment device 61 when adjusting the needle 422 of the syringe 42 can be reduced.

[0115] The needle 422 of the syringe 42 can be adjusted by the adjustment device 61 to accurately insert into the insertion hole of the container with the medicine solution, Figure 7 The operation flow of the adjustment device 61 is shown in the following Figures 6A-6C First, the step E1 is performed to provide the syringe 62 and the inserted container (e.g. a medicine bottle or a medicine bag). Second, the step E2 is performed to insert the needle 422 into the container by the mutual approach of the first adjustment unit 611 and the second adjustment unit 612 for guidance. Third, the step E3 is performed to extract or inject the solution from or into the container by the syringe 62.

[0116] The use of the needle cover plugging device 10 in the above step A3 or step B4 is described as follows. Figure 3B is the step flow chart of the needle cover plugging system of an embodiment of the present application to remove the needle cover (hereinafter referred to as cover removal). Please refer to Figures 1-2B together. As shown, first, the step D1 is performed to clamp the syringe 42 with the needle cover 423 by the first clamping element 41. Next, the step D2 is performed to clamp the needle cover 423 by the needle cover plugging device 10.
