Description

Technical Field

[0001] The present invention relates to medical devices, and in particular to a medical device production line. Background Art

[0002] Some medical devices include an inner needle assembly and an outer needle assembly. The inner needle assembly includes an inner needle hub and an inner needle, while the outer needle assembly includes an outer needle hub and an outer needle. The outer needle sleeve fits over the inner needle, while the outer needle hub fits over the inner needle hub. Automating the production of these medical devices and improving production efficiency is a pressing issue. Summary of the Invention

[0003] In view of this, it is necessary to provide an improved medical device production line, which can realize the automated production of medical devices including an inner needle seat, an inner needle, an outer needle seat, and an outer needle, thereby improving production efficiency.

[0004] The present invention first provides a medical device production line, the materials of which include an inner needle seat, an inner needle, an outer needle seat and an outer needle, and the process steps include an outer needle seat loading device, an outer needle loading device, an external glue dispensing device and an external curing device. The outer needle seat loading device is used to assemble the outer needle seat to the inner needle seat, the outer needle loading device is used to assemble the outer needle to the outer needle seat and sleeve it on the outside of the inner needle, the external glue dispensing device is used to apply glue to the connection between the outer needle and the outer needle seat, and the external curing device is used to cure the glue at the connection between the outer needle and the outer needle seat.

[0005] By adopting the above technical solution, the assembly of the inner needle seat, the outer needle seat and the outer needle can be automated, thereby improving production efficiency.

[0006] In one embodiment of the present invention, the medical device production line also includes an external alignment device, which is used to align the blade surface of the outer needle and the blade surface of the inner needle. The external dispensing device, the external alignment device and the external curing device are distributed in sequence according to the process.

[0007] By adopting the above technical solution, if the outer needle holder feeding device only provides the outer needle holder without assembling the outer needle holder and the inner needle holder, and the outer needle holder and the inner needle holder are assembled after the outer needle feeding device completes the assembly of the outer needle and the outer needle holder, and if the inner needle holder and the outer needle holder are to be assembled, then the relative positions of the outer needle holder and the outer needle have been determined, that is, the outer needle and the outer needle holder need to pass through the external glue dispensing device and the external curing device so that the glue at the connection between the outer needle and the outer needle holder has been cured, otherwise the outer needle holder and the outer needle are likely to separate when the inner needle holder and the outer needle holder are assembled. After the relative positions of the inner needle holder and the outer needle holder have been determined, the external alignment device needs to ensure that the blade surface of the inner needle and the blade surface of the outer needle are in an aligned state, which will result in the inner needle holder and the outer needle holder being unable to be assembled when the blade surface of the inner needle and the blade surface of the outer needle are in an aligned state. In other words, after the inner needle holder and the outer needle holder are assembled, it may interfere with the alignment of the blade surface of the inner needle and the blade surface of the outer needle. Therefore, the outer needle seat and the inner needle seat are first assembled by the outer needle seat loading device, and then the outer needle and the outer needle seat are assembled by the outer needle loading device. The external alignment device can align the blade surface of the outer needle and the blade surface of the inner needle when the relative position of the outer needle and the outer needle seat has not been completely determined, thereby realizing both the assembly of the outer needle seat and the inner needle seat and the alignment of the blade surface of the outer needle and the blade surface of the inner needle.

[0008] In one embodiment of the present invention, the external alignment device includes an external detection component and an external adjustment component. The external detection component is used to detect whether the blade surface of the inner needle and the blade surface of the outer needle are in an aligned state, and the external adjustment component is used to drive the outer needle to move until the blade surface of the outer needle and the blade surface of the inner needle are aligned.

[0009] By adopting the above technical solution, the external detection component detects whether the blade surface of the outer needle and the blade surface of the inner needle are in an aligned state. If the blade surface of the outer needle and the blade surface of the inner needle are in a non-aligned state, the external adjustment component drives the outer needle to move so that the blade surface of the outer needle and the blade surface of the inner needle are aligned. The external detection component again detects whether the blade surface of the outer needle and the blade surface of the inner needle are in an aligned state. If the blade surface of the outer needle and the blade surface of the inner needle are in an aligned state, the external adjustment component does not need to drive the outer needle to move. Finally, the blade surface of the outer needle and the blade surface of the inner needle are automatically aligned.

[0010] In one embodiment of the present invention, the medical device production line also includes a testing device, which is used to detect whether the outer needle seat and the inner needle seat can be separated and assembled. The external dispensing device, the external curing device and the testing device are distributed in sequence according to the process.

[0011] With this technical solution, when the external dispensing device dispenses glue at the connection between the outer needle holder and the outer needle, the outer needle holder is already assembled to the inner needle holder. Therefore, the inner and outer needle holders may become stuck together and unable to be separated. However, during normal use, the inner and outer needle holders must be separated. Therefore, a test device is required to verify that the outer and inner needle holders can be separated and reassembled to avoid affecting normal use.

[0012] In one embodiment of the present invention, the medical device production line also includes a waste rejection device and a material replenishing device. The waste rejection device is used to reject unqualified materials after testing by the testing device, and the material replenishing device is used to replenish qualified materials to the waste rejection device or remove the remaining qualified materials. The testing device, the waste rejection device, and the material replenishing device are distributed in sequence according to the process.

[0013] By adopting this technical solution, materials are not automatically produced one by one, but rather are automatically produced simultaneously in batches of multiple materials. If some materials are rejected by the reject device because they are deemed unqualified by the testing device, the refill device needs to replenish the reject device with qualified materials, so that the same batch of materials can complete subsequent automated production.

[0014] In one embodiment of the present invention, the material also includes a sheath, and the medical device production line also includes a sleeve device, which is used to assemble the sheath and the outer needle seat. The testing device is also used to detect whether the sheath is sleeved on the outside of the outer needle. The external curing device, the sleeve device and the testing device are distributed in sequence according to the process.

[0015] By adopting the technical solution, the testing device can not only test whether the outer needle seat and the inner needle seat can be separated and assembled, but also test whether the sheath is arranged outside the outer needle, thereby improving utilization.

[0016] In one embodiment of the present invention, the material also includes a sheath, and the medical device production line also includes a flipping device, a siliconizing device and a sleeve connecting device. The flipping device is used to flip the outer needle and the inner needle so that the needle tip of the outer needle and the needle tip of the inner needle are located at the lowest position of the material. The siliconizing device is used to siliconize the needle tip of the outer needle and the needle tip of the inner needle. The sleeve connecting device is used to assemble the sheath and the outer needle seat. The external curing device, the flipping device, the siliconizing device and the sleeve connecting device are distributed in sequence according to the process.

[0017] By adopting the above technical solution, the sheath covers the tips of the outer needle and the inner needle. Therefore, the siliconization device needs to be placed before the sleeve connection device to prevent the sheath from interfering with the siliconization of the tips of the outer needle and the inner needle seat. When siliconization is required, the tips of the outer needle and the inner needle need to be at the lowest position in the entire material to prevent silicone oil from flowing along the outer needle into the connection between the outer needle and the outer needle seat, and the inner needle from entering the connection between the inner needle and the inner needle seat. Therefore, before the siliconization device is installed, the outer needle and the inner needle need to be flipped to ensure that the tips of the outer needle and the inner needle are at the lowest position in the entire material.

[0018] In one embodiment of the present invention, the medical device production line further includes an inner needle seat loading device, an inner needle loading device, an internal glue dispensing device, and an internal curing device in sequence according to the process. The inner needle seat loading device is used to provide the inner needle seat, the inner needle loading device is used to assemble the inner needle to the inner needle seat, the internal glue dispensing device is used to apply glue to the connection between the inner needle and the inner needle seat, and the internal curing device is used to cure the glue at the connection between the inner needle and the inner needle seat.

[0019] In one embodiment of the present invention, the medical device production line also includes an internal alignment device, which is used to align the blade surface of the inner needle and a specific part of the inner needle seat. The internal gluing device, the internal alignment device and the internal curing device are distributed in sequence according to the process.

[0020] In one embodiment of the present invention, the internal alignment device includes an internal detection component and an internal adjustment component. The internal detection component detects whether the blade surface of the inner needle and the specific part of the inner needle seat are in an alignment state. The internal adjustment component is used to drive the blade surface of the inner needle to move to align with the specific part of the inner needle seat.

[0021] In one embodiment of the present invention, the medical device production line also includes a first conveying device, which conveys materials in sequence through the outer needle seat loading device, the outer needle loading device, the external dispensing device and the external curing device. The first conveying device includes a clamping member and a clamping drive member, and the clamping drive member drives the clamping member to clamp the inner needle or the outer needle.

The terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] The embodiment of the present invention first provides Figure 1 and Figure 2 The medical device production line shown includes, in order of process steps, an inner needle seat loading device 100, an inner needle loading device 200, an inner glue dispensing device 300, an inner alignment device 400, an inner curing device 500, an outer needle seat loading device 600, an outer needle loading device 700, an outer glue dispensing device 800, an outer alignment device 900, an outer curing device 1000, a flipping device 1100, a siliconizing device 1200, a sleeve connection device 1300, a testing device 1400, a waste rejection device 1500, and a refilling device 1600. The assembly of the inner needle seat 1712, outer needle seat 1722, and outer needle 1721 can be automated, improving production efficiency.

[0033] Reference Figure 3 and Figure 4 Material 1700 includes an inner needle assembly 1710, an outer needle assembly 1720, and a sheath 1730. The inner needle assembly 1710 includes an inner needle 1711 and an inner needle seat 1712, and the outer needle assembly 1720 includes an outer needle 1721 and an outer needle seat 1722. The outer needle 1721 is sleeved on the outside of the inner needle 1711, the sheath 1730 is sleeved on the outside of the outer needle 1721, and the outer needle seat 1722 is sleeved on the outside of the inner needle seat 1712.

[0034] Reference Figure 1 The inner needle seat loading device 100 is used to provide the inner needle seat 1712, the inner needle loading device 200 is used to assemble the inner needle 1711 to the inner needle seat 1712, the internal glue dispensing device 300 is used to apply glue to the connection between the inner needle 1711 and the inner needle seat 1712, the internal alignment device 400 is used to align the blade surface of the inner needle 1711 and the specific part of the inner needle seat 1712, and the internal curing device 500 is used to cure the glue at the connection between the inner needle 1711 and the inner needle seat 1712.

[0035] The internal alignment device 400 includes an internal detection component 410 and an internal adjustment component 420. The internal detection component 410 detects whether the blade surface of the inner needle 1711 and a specific part of the inner needle seat 1712 are in an aligned state. The internal adjustment component 420 is used to drive the blade surface of the inner needle 1711 to move to align with a specific part of the inner needle seat 1712. The internal adjustment component 420 includes an internal clamping member 421, an internal clamping drive member 422 and an internal rotating member 423. The internal clamping member 421, the internal clamping drive member 422 and the internal rotating member 423 are connected in sequence. The internal clamping member 421 is used to clamp the inner needle 1711, and the internal clamping drive member 422 is used to drive the internal clamping member 421 to clamp the inner needle 1711 and release the inner needle 1711. The inner rotating member 423 is used to drive the inner clamping driving member 422 to rotate relative to a specific part of the inner needle seat 1712, thereby driving the blade surface of the inner needle 1711 to rotate relative to the specific part of the inner needle seat 1712 through the inner clamping driving member 422 and the inner clamping member 421.

[0036] The outer needle seat loading device 600 is used to assemble the outer needle seat 1722 to the inner needle seat 1712, the outer needle loading device 700 is used to assemble the outer needle 1721 to the outer needle seat 1722 and sleeve it on the outside of the inner needle 1711, the external glue dispensing device 800 is used to apply glue to the connection between the outer needle 1721 and the outer needle seat 1722, the external alignment device 900 is used to align the blade surface of the outer needle 1721 and the blade surface of the inner needle 1711, and the external curing device 1000 is used to cure the glue at the connection between the outer needle 1721 and the outer needle seat 1722.

[0037] If the outer needle seat loading device 600 only provides the outer needle seat 1722 without assembling the outer needle seat 1722 and the inner needle seat 1712, and the outer needle seat 1722 and the inner needle seat 1712 are assembled after the outer needle 1721 and the outer needle seat 1722 are assembled by the outer needle loading device 700, then the outer needle seat 1722 and the inner needle seat 1712 are assembled. To assemble the inner needle seat 1712 and the outer needle seat 1722, the relative positions of the outer needle seat 1722 and the outer needle 1721 must be determined. That is, the outer needle 1721 and the outer needle seat 1722 must pass through the external glue dispensing device 800 and the external curing device 1000 so that the glue at the connection between the outer needle 1721 and the outer needle seat 1722 has been cured. Otherwise, the outer needle seat 1722 and the outer needle 1721 may be easily separated while the inner needle seat 1712 and the outer needle seat 1722 are assembled. After the relative positions of the inner needle hub 1712 and the outer needle hub 1722 have been determined, the outer alignment device 900 needs to ensure that the blade surface of the inner needle 1711 and the blade surface of the outer needle 1721 are aligned. This may result in the inner needle hub 1712 and the outer needle hub 1722 being unable to be assembled when the blade surface of the inner needle 1711 and the blade surface of the outer needle 1721 are aligned. In other words, after the inner needle hub 1712 and the outer needle hub 1722 are assembled, they may interfere with the alignment of the blade surface of the inner needle 1711 and the blade surface of the outer needle 1721. Therefore, the outer needle seat 1722 and the inner needle seat 1712 are first assembled by the outer needle seat loading device 600, and then the outer needle 1721 and the outer needle seat 1722 are assembled by the outer needle loading device 700. The external alignment device 900 can align the blade surface of the outer needle 1721 and the blade surface of the inner needle 1711 when the relative position of the outer needle 1721 and the outer needle seat 1722 has not been completely determined, thereby realizing both the assembly of the outer needle seat 1722 and the inner needle seat 1712 and the alignment of the blade surface of the outer needle 1721 and the blade surface of the inner needle 1711.

[0038] The external alignment device 900 includes an external detection component 910 and an external adjustment component 920. The external detection component 910 is used to detect whether the blade surface of the inner needle 1711 and the blade surface of the outer needle 1721 are in an aligned state. The external adjustment component 920 is used to drive the outer needle 1721 to move until the blade surface of the outer needle 1721 is aligned with the blade surface of the inner needle 1711. The external adjustment component 920 includes an external clamping member 921, an external clamping drive member 922, an external rotating member 923 and an external translation member 924. The external clamping member 921, the external clamping drive member 922, the external rotating member 923 and the external translation member 924 are connected in sequence. The external clamping member 921 is used to clamp the outer needle 1721, and the external clamping drive member 922 is used to drive the external clamping member 921 to clamp the outer needle 1721 and release the outer needle 1721. The outer rotating member 923 is used to drive the outer clamping driver 922 to rotate relative to the inner needle 1711, thereby causing the blade surface of the outer needle 1721 to rotate relative to the blade surface of the inner needle 1711 through the outer clamping driver 922 and the outer clamping member 921. The outer translating member 924 is used to drive the outer rotating member 923 to translate relative to the inner needle 1711, thereby causing the blade surface of the outer needle 1721 to translate relative to the blade surface of the inner needle 1711 through the outer rotating member 923, the outer clamping driver 922, and the outer clamping member 921. The outer detection assembly 910 detects whether the blade surfaces of the outer needle assembly 1720 and the inner needle assembly 1710 are aligned. If the blade surface of outer needle assembly 1720 and the blade surface of inner needle assembly 1710 are not aligned, external adjustment assembly 920 drives outer needle assembly 1720 to move, aligning the blade surface of outer needle assembly 1720 with the blade surface of inner needle assembly 1710. External detection assembly 910 again detects whether the blade surface of outer needle assembly 1720 and the blade surface of inner needle assembly 1710 are aligned. If the blade surface of outer needle assembly 1720 and the blade surface of inner needle assembly 1710 are aligned, external adjustment assembly 920 does not need to drive outer needle assembly 1720 to move. Ultimately, the blade surface of outer needle assembly 1720 and the blade surface of inner needle assembly 1710 are automatically aligned. During the process of the outer adjustment assembly 920 driving the blade of the outer needle assembly 1720 to move relative to the blade of the inner needle assembly 1710, it is necessary to drive the blade of the outer needle assembly 1720 to face the same direction as the blade of the inner needle assembly 1710, and also to drive the blade of the outer needle assembly 1720 and the blade of the inner needle assembly 1710 to be aligned in the axial direction, so as to ensure that the blade of the outer needle assembly 1720 and the blade of the inner needle assembly 1710 are aligned. Therefore, it is necessary to drive the blade of the outer needle assembly 1720 to rotate relative to the blade of the inner needle assembly 1710 by the outer rotating member 923, and also to drive the blade of the outer needle assembly 1720 to translate relative to the blade of the inner needle assembly 1710 by the outer translation member 924, so as to finally achieve the alignment of the blade of the outer needle assembly 1720 with the blade of the inner needle assembly 1710.

[0039] Reference Figure 2The flipping device 1100 is used to flip the outer needle 1721 and the inner needle 1711 so that the needle tips of the outer needle 1721 and the inner needle 1711 are located at the lowest position of the material 1700. The siliconizing device 1200 is used to siliconize the needle tips of the outer needle 1721 and the inner needle 1711. The sleeve device 1300 is used to assemble the sheath 1730 and the outer needle seat 1722. The sheath 1730 covers the needle tips of the outer needle 1721 and the inner needle 1711. Therefore, the siliconizing device 1200 needs to be installed before the sleeve device 1300 to prevent the sheath 1730 from interfering with the siliconization of the needle tips of the outer needle 1721 and the inner needle seat 1712. When siliconization is required, the tips of the outer needle 1721 and the inner needle 1711 must be at the lowest position in the entire material 1700 to prevent silicone oil from flowing along the outer needle 1721 into the connection between the outer needle 1721 and the outer needle seat 1722, and the inner needle 1711 from flowing into the connection between the inner needle 1711 and the inner needle seat 1712. Therefore, before siliconization device 1200 is used, outer needle 1721 and inner needle 1711 must be turned over to ensure that the tips of outer needle 1721 and inner needle 1711 are at the lowest position in the entire material 1700.

[0040] The testing device 1400 is used to detect whether the outer needle seat 1722 and the inner needle seat 1712 can be separated and assembled, and whether the sheath 1730 is positioned outside the outer needle 1721. The reject device 1500 is used to reject unqualified material 1700 after testing by the testing device 1400. The replenishing device 1600 is used to replenish qualified material 1700 to the reject device 1500 or remove the remaining qualified material 1700. When the external glue dispensing device 800 dispenses glue at the connection between the outer needle seat 1722 and the outer needle 1721, the outer needle seat 1722 is already assembled to the inner needle seat 1712. Therefore, the inner needle seat 1712 and the outer needle seat 1722 may be stuck together by glue and cannot be separated. However, during normal use of the material 1700, the inner needle seat 1712 and the outer needle seat 1722 need to be separated. Therefore, the testing device 1400 needs to test whether the outer needle seat 1722 and the inner needle seat 1712 can be separated and assembled to avoid affecting normal use. The materials 1700 are not automatically produced one by one, but are automatically produced synchronously in batches of multiple materials 1700. When part of the materials 1700 are rejected by the rejection device 1500 because they are judged as unqualified after being tested by the testing device 1400, the feeding device 1600 needs to replenish the rejection device 1500 with qualified materials 1700 so that the same batch of materials 1700 can complete subsequent automated production. The testing device 1400 can not only test whether the outer needle seat 1722 and the inner needle seat 1712 can be separated and assembled, but also test whether the sheath 1730 is mounted on the outside of the outer needle 1721, thereby improving utilization.

[0041] The medical device production line also includes a first transfer device 1800 and a second transfer device 1900. The inner needle holder loading device 100, inner needle loading device 200, inner glue dispensing device 300, inner alignment device 400, inner curing device 500, outer needle holder loading device 600, outer needle loading device 700, outer glue dispensing device 800, outer alignment device 900, and outer curing device 1000 are arranged in a circular pattern around the first transfer device 1800. The flipping device 1100, siliconizing device 1200, sleeve connection device 1300, testing device 1400, waste rejection device 1500, and feeding device 1600 are arranged in a circular pattern around the second transfer device 1900. Material 1700 is moved from the first transfer device 1800 to the second transfer device 1900 via the flipping device 1100.

[0042] The first transfer device 1800 includes a plurality of clamping members 1810 and a plurality of clamping driving members 1820. The clamping members 1810 and the clamping driving members 1820 correspond one to one. The clamping driving member 1820 drives the clamping member 1810 to clamp the inner needle 1711 or the outer needle 1721. When only the inner needle 1711 is present, the clamping driving member 1820 drives the clamping member 1810 to clamp the inner needle 1711. When the outer needle 1721 is sleeved outside the inner needle 1711, the clamping driving member 1820 drives the clamping member 1810 to clamp the outer needle 1721. When it is necessary to operate the material 1700 and this will interfere with the clamping member 1810, the clamping driving member 1820 drives the clamping member 1810 to be released. When material 1700 needs to be manipulated without interfering with clamping member 1810, or when no manipulation of material 1700 is required, clamping member 1820 drives clamping member 1810 into a clamping state. Inner needle 1711 and outer needle 1721 are relatively long, and clamping member 1810 clamps inner needle 1711 and outer needle 1721 as much as possible to prevent them from moving freely.

[0043] It is understandable that, referring to Figure 5 , the projections of the internal curing device 500 and the internal alignment device 400 in the horizontal plane overlap.

[0044] The various technical features of the above-described embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the various technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
