Description

[Technical Field]

[0001] The present invention relates to a used needle separation device in which a drive rotation engaging tooth profile is formed along one periphery, and a used needle storage non-engaging portion and a used needle separation (withdrawal) engaging tooth profile are formed along the other periphery. [Background technology]

[0002] There are various types of syringes depending on the use, such as general-purpose syringes, syringes for collecting blood, syringes for insulin, intravenous injection catheters, and vacuum needles specifically for collecting blood.

[0003] The needle hub of the syringe may be of an integrated type, an insert type, or a luer lock type, which is attached to the end of the syringe body.

[0004] Also, referring to FIG. 16, when the needle 3 is fixed to the hub 2, the syringe needle hub 1 is configured so that only a portion of the needle 3 is inserted into the hub 2, and this portion can be coated with adhesive.

[0005] Furthermore, the length and thickness of the needle 3 of the needle hub 1 may vary.

[0006] Furthermore, the diameter of the hub 2 (large diameter, small diameter, etc.) and the shape (cylindrical, cross-shaped) may also differ depending on the type of syringe.

[0007] A conventional used syringe needle separation device is disclosed in, for example, a patent document (Korean Patent Registration No. 10-1588170).

[0008] In the automatic needle separating and retrieving device disclosed in the patent document, the needle that has passed through a pair of rotating needle separating gears is pulled again by a pair of needle handling gears to separate it from the syringe.

[0009] However, the automatic injection needle separating and retrieving device disclosed in the patent document has the following problems.

[0010] First, when the needle length is moderate as in the patent document, the needle tip is pulled from the state where it is in contact with the meshing part of the needle processing gear, so it needs to be operated for a long time corresponding to the length of the needle.

[0011] Secondly, when the needle is very short, such as in an insulin syringe, it may be possible to insert the needle through the needle hole, but the needle tip may not reach the meshing part of the needle handling gear, making it impossible to separate the needle.

[0012] Third, if the needle is very long, even if the needle tip reaches the meshing part of the needle processing gear, the user must hold the syringe body in order to process it, which is very inconvenient and may require additional time to separate the needle.

[0013] Fourth, depending on the diameter and shape of the needle hub, it may not be possible to attach it to the syringe mounting part.

[0014] As described above, conventional automatic injection needle separating and collecting devices are unable to process needles and needle hubs according to their types, and therefore it is necessary to provide a device for processing them individually.

[0015] On the other hand, in a dedicated blood collection needle or catheter needle, for example, as shown in FIG. 24, which shows a dedicated blood collection needle hub 5, the needle 7 penetrates a hub 6, and the hub 6 and needle 7 are fixed with an adhesive.

[0016] Unlike a typical syringe where only part of the needle tip is inserted (see Figure 16), such blood collection needle hubs 5 and catheter needle hubs are fixed in a pierced state, and the adhesive strength is so strong that the needle cannot be pulled out, leaving behind a partially cut needle 7' that does not separate completely, as shown in Figure 25. Furthermore, since the needle 7 penetrates the hub 6, the needle 7 blocks the hub 6, and it is not possible to cut only the hub 6 with a blade or the like.

[0017] Therefore, the blood collection needle hub 5 and the IV catheter needle hub had to be discarded with the needle 7' remaining in the hub, which could not be completely removed. [Prior art documents] [Patent documents]

[0018] [Patent Document 1] Korean Patent Registration No. 10-1588170 Summary of the Invention [Problem to be solved by the invention]

[0019] The present invention aims to solve the above-mentioned problems and other problems.

[0020] Another object of the present invention is to provide a used injection needle separation device that can quickly separate needles regardless of the shape of the needle hub or the length of the needle.

[0021] Another object of the present invention is to provide a used needle separation device that allows a needle dedicated to blood collection or catheterization to be easily withdrawn from the hub. [Means for solving the problem]

[0022] In order to achieve the above and other objects, according to one aspect of the present invention, there is provided a used needle separation device comprising: a case formed with an insertion port for a used needle; first and second gears supported by a gear support bracket mounted on the case and separating a used needle inserted into the insertion port; and a drive unit for rotating the first and second gears, wherein the first and second gears are formed with first and second driving rotation meshing tooth profiles along one side peripheral edges, and are formed with first and second accommodating non-meshing portions that accommodate the used needle, and first and second separating meshing tooth profiles that mesh with and separate the used needle, along the other side peripheral edges. [Effects of the Invention]

[0023] The effects of the used syringe needle separating device according to the present invention will be explained as follows.

[0024] According to at least one embodiment of the present invention, a used injection needle separation device can be provided in which the first gear and the second gear that separate the needle are formed with a first non-meshing receiving portion and a second non-meshing receiving portion, so that the needle start portion is directly positioned on the first separation meshing tooth profile and the second separation meshing tooth profile, thereby significantly shortening the needle separation time regardless of the needle length.

[0025] According to at least one embodiment of the present invention, by providing a guide jig portion according to the shape of the needle hub, the needle hub is placed directly on the first separation engaging tooth form and the second separation engaging tooth form, thereby providing a used injection needle separation device that quickly separates needles regardless of the shape of the needle hub.

[0026] According to at least one embodiment of the present invention, by forming the receiving non-engagement portion in both directions by 180 degrees, it is possible to provide a used needle separation device that can be rotated by 180 degrees to reduce power consumption.

[0027] According to at least one embodiment of the present invention, a start button is disposed on one side of the case of the insertion port, and after a user inserts the needle hub into the insertion port, the user pushes the syringe body sideways to press the start button to activate the device, thereby providing a used syringe needle separation device that improves separation efficiency.

[0028] According to at least one embodiment of the present invention, when a dedicated needle hub is placed inside a high-frequency coil that heats metal and heated, the heat from the heated needle is transferred to the adhesive, reducing the adhesive strength, and therefore a used injection needle separation device can be provided that allows the entire needle to be easily pulled out from the dedicated needle hub.

[0029] According to at least one embodiment of the present invention, a used injection needle separation device can be provided that can further improve convenience of use by touching a first start switch at the same time as inserting a needle hub, thereby sequentially applying power to the high-frequency induction heater and the driving unit.

[0030] Further scope of applicability of the present invention will become apparent from the following detailed description, however, the detailed description and specific embodiments, such as preferred embodiments of the invention, should be understood as illustrative only, since various changes and modifications within the spirit and scope of the invention will be apparent to those skilled in the art.

[0041] FIG. 1 is an external perspective view of a used syringe needle separation device 10 according to a preferred embodiment of the present invention, FIG. 2 is an external perspective view of the device with the lid case 130 of FIG. 1 removed, FIG. 3 is an external perspective view of the device with the main parts of FIG. 2 separated, FIG. 4 is a plan view of the bottom case 110, and FIG. 5 is an external perspective view of the lid case 130.

[0042] 1, a used syringe needle separation device 10 according to an embodiment of the present invention may include a case 100. The case 100 may include a plate-shaped bottom case 110 and a cylindrical cover case 130.

[0043] Various components may be fixed or supported on the bottom case 110 as shown in FIG. 2. The bottom case 110 may include a discharge hole 111 at the front center as shown in FIGS. 3 and 4. The discharge hole 111 allows separated needles to fall into the needle collection container 900. An inclined surface 112 that slopes downward toward the discharge hole 111 may be formed in front of the discharge hole 111. The inclined surface 112 can guide the separated needles so that they slide down toward the discharge hole 111 if they bounce down.

[0044] As shown in FIG. 4, the bottom case 110 may include an additional discharge hole 113 at the rear center. The additional discharge hole 113 allows needles that have been manually separated to pass through. An additional inclined surface 114 that slopes downward toward the additional discharge hole 113, similar to the inclined surface 112, may be formed behind the additional discharge hole 113. As shown in FIGS. 2 and 3, a shielding wall 115 may be formed to protrude upward and cover the left, right, and front of the additional discharge hole 113 and the additional inclined surface 114. The shielding wall 115 may be a U-shaped pillar. The shielding wall 115 allows needles that have been manually separated to fall into the additional discharge hole 113 even if they bounce.

[0045] 4, the bottom case 110 may include a light irradiation hole 116. The light irradiation hole 116 may be disposed between the discharge hole 111 and the additional discharge hole 113. The light irradiation hole 116 may be a passage through which light from the sterilization lamp 700 is irradiated onto the needle collection container 900. When power is applied to the sterilization lamp 700, the UVC-LED lights up, thereby sterilizing the separated needles collected in the needle collection container 900.

[0046] 5, the cover case 130 may have a hexahedral shape that covers the top of the bottom case 110. The cover case 130 may include front, rear, left and right sides and front plates 130a to 130e.

[0047] The corners of the front plate 130a and top plate 130e may be formed as angled plates 130f pressed at a 45 degree angle.

[0048] The inclined plate 130f may be formed with an insertion port 131. A needle hub of a used injection needle can be inserted through the insertion port 131. A step 132 for locking the body of a used syringe may be formed around the insertion port 131.

[0049] The inclined plate 130f may have a through-hole 133 formed therein in which the second start switch 340 is disposed.

[0050] The inclined plate 130f may be formed with an elongated hole 134 in which a gripping portion 530 (described later) is slidably disposed.

[0051] A through-hole 138 may be formed in a side surface of the case where the front plate 130a, the inclined plate 130f, and the upper plate 130e intersect. The through-hole 138 may be adjacent to the insertion opening 131 in a direction perpendicular to the insertion opening 131. A start button 350 that touches the first start switch 330 may be disposed in the through-hole 138.

[0052] The upper plate 130e may have a through-hole 135 through which a display window 810 of the counter 800 is disposed. The counter 800 may have a rectangular cylinder mounted on the top surface of the sterilization lamp 700. The rectangular cylinder of the counter 800 may have the function of bouncing the separated needles backward, colliding with them, and dropping them into the discharge hole 111. A metal plate (not shown) may be provided at the location where the separated needles collide to prevent scratches, etc. Furthermore, if the needle is very long, for example, 5 cm or longer, the tip of the needle may strike the metal plate (not shown), causing the separated needle tip to face downward and ensure collection in the needle collection container 900. Furthermore, the metal plate (not shown) is preferably made of stainless steel, which does not rust due to blood or medication on the needle tip. The pulse-type counter 800 may display a number in the display window 810 that increments by one each time power is applied and a needle is separated.

[0053] The upper plate 130e may be formed with a manual needle separation through-hole 136 and a manual scalpel blade separation through-hole 138. The manual needle separation through-hole 136 and the manual scalpel blade separation through-hole 138 may be formed directly above the shielding wall 115. The manual needle separation through-hole 136 allows the needle 3 to be separated by inserting the needle hub 1 from top to bottom, pulling it sideways, and then bending it. The scalpel blade separation through-hole 138 allows the scalpel blade to be separated by inserting the scalpel with the fixing part of the scalpel to which the scalpel blade is fixed facing downwards and pulling it out.

[0054] The upper plate 130e may be formed with a groove 137 in which a used syringe with an unseparated needle can be temporarily placed.

[0055] FIG. 6 is an enlarged perspective view of the first gear 200a and the second gear 200b of FIG.

[0056] 6, a used needle separation device 10 according to an embodiment of the present invention may include a first gear 200a and a second gear 200b for separating (pulling out) a used needle. The first gear 200a and the second gear 200b may be a pair of spur gears.

[0057] The first gear 200a and the second gear 200b, which are essential components of the present invention, may include a first driving rotational meshing tooth profile 210a and a second driving rotational meshing tooth profile 210b formed along the entire periphery of one side. The first driving rotational meshing tooth profile 210a and the second driving rotational meshing tooth profile 210b can mesh with and rotate the first gear 200a and the second gear 200b. In this embodiment, the first gear 200a acts as a driving gear and the second gear 200b acts as a driven gear, but the reverse is also possible.

[0058] Furthermore, the first gear 200a and the second gear 200b, which are essential components of the present invention, may include a first storage non-meshing portion 220a and a second storage non-meshing portion 220b formed along the other side periphery, and a first separation meshing tooth profile 225a and a second separation meshing tooth profile 225b. The first storage non-meshing portion 220a and the second storage non-meshing portion 220b can store a used injection needle 3 as close as possible to the first separation meshing tooth profile 225a and the second separation meshing tooth profile 225b. The first separation meshing tooth profile 225a and the second separation meshing tooth profile 225b can mesh with and separate a stored used injection needle 3. The first storage non-meshing portion 220a and the second storage non-meshing portion 220b may be formed on only one side, or may be formed at 180-degree intervals as in this embodiment. Furthermore, the space between the first accommodating non-mating portion 220a and the second accommodating non-mating portion 220b can be disposed at a position opposite the insertion opening 131 and communicating with each other.

[0059] In this embodiment, the number of the first driving rotation meshing tooth profiles 210a and the second driving rotation meshing tooth profiles 210b is 30 each, the first accommodating non-meshing portion 220a and the second accommodating non-meshing portion 220b each have six teeth removed from both sides, and the first separating meshing tooth profiles 225a and the second separating meshing tooth profiles 225b have nine teeth capable of separating used injection needles 3.

[0060] By forming such first and second accommodating non-meshing portions 220a and 220b, in the case of a needle of a normal length, the needle can be inserted as much as possible into the space between the first accommodating non-meshing portion 220a and the second accommodating non-meshing portion 220b as shown in FIG. 12, thereby extremely shortening the separation time, and in the case of a needle of a very short length, the needle hub 2 can be inserted as much as possible into the space between the first accommodating non-meshing portion 220a and the second accommodating non-meshing portion 220b as shown in FIG. 13, thereby allowing separation.

[0061] The first gear 200a and the second gear 200b may be rotatably supported by a first gear support bracket 230a and a second gear support bracket 230b, as shown in Figures 2 and 3. The first gear support bracket 230a and the second gear support bracket 230b may be a pair.

[0062] The first gear support bracket 230a and the second gear support bracket 230b may include a first foot bracket 231a and a second foot bracket 231b coupled to the bottom case 110, and a first gear bracket 232a and a second gear bracket 232b that rotatably support the first gear 200a and the second gear 200b.

[0063] A first rotating shaft (not shown) connected to the output shaft of the driving unit 300 is provided at the center of the first gear 200a, and both ends of the first rotating shaft (not shown) may be rotatably supported between the first gear bracket 232a and the second gear bracket 232b. The first rotating shaft (not shown) may be a driving shaft of the first gear 200a.

[0064] The second gear 200b may be rotatably supported between the first gear bracket 232a and the second gear bracket 232b via a second rotation shaft (not shown). The second rotation shaft (not shown) may be configured with a bearing (not shown). The bearing (not shown) may be a driven shaft of the second gear 200b.

[0065] The first gear support bracket 230a and the second gear support bracket 230b may include a plurality of first cross bars 233a and second cross bars 233b that secure the first gear bracket 232a and the second gear bracket 232b together. The first cross bars 233a and the second cross bars 233b may be fastened together by fastening elements.

[0066] Such first crossbar 233a and second crossbar 233b stably hold the first gear 200a and the second gear 200b without twisting, and prevent the second gear 200b from falling off during the process of separating the used injection needle 3.

[0067] 3, the first and second rotation shafts (not shown) of the first gear 200a and the second gear 200b may be arranged in parallel at the bottom and top, with at least the first rotation shaft (not shown) being arranged forward relative to the second rotation shaft (not shown). Such misalignment of the first and second rotation shafts (not shown) may cause the used syringe to fall under its own weight immediately after needle 3 is automatically detached, when a used syringe is inserted into insertion port 131 at a 45-degree angle as shown in FIG.

[0068] 2 and 3, the used needle separating device 10 according to the embodiment of the present invention may include a driving unit 300. The driving unit 300 can transmit a rotational force to the first gear 200a.

[0069] The driving unit 300 may include a motor 310. The motor 310 may be supplied with power from a battery (not shown) installed in the bottom case 110 as in this embodiment, or may be supplied with an external power source.

[0070] The driving unit 300 may include a reduction gear unit 320. The reduction gear unit 320 may be supported by the first gear support bracket 230a. The reduction gear unit 320 may support the motor 310. The reduction gear unit 320 may reduce the rotation speed of the motor 310. An output shaft (not shown) of the reduction gear unit 320 may be connected to a rotation shaft (not shown) of the first gear 200a. Of course, the reduction gear unit 320 and the motor 310 may be mounted and supported on the bottom case 110.

[0071] When the first start switch 330 or the second start switch 340 is activated, power is applied to the driving unit 300, thereby driving the first gear 200a and the second gear 200b.

[0072] First start switch 330 may be configured as a limit switch. A start button 350 may be provided on the lever of first start switch 330. Start button 350 can be activated by inserting a used syringe into insertion port 131 and then pulling and pushing it sideways, as shown in FIG. 14. That is, first start switch 330 may be applied when only needle 3 is inserted into small diameter hole 513, as shown in FIG. 12a. Since needle 3 can be bent by pulling it sideways, first start switch 330 can be operated by the syringe body.

[0073] The user can directly press the second start switch 340 to apply power. The second start switch 340 may be configured as a push button switch. That is, as shown in FIG. 13a, the second start switch 340 may be used when the hub 2 is inserted into the large diameter hole 513 or the cross hole 514. When the hub 2 is fully inserted into the large diameter hole 513 or the cross hole 514 and is difficult to bend sideways like the needle 3, the start button 350 may not be operable on the syringe body. In such cases, the user can press the second start switch 340. When the stop switch 360 cuts off the power supply to the drive unit 300, the drive of the first gear 200a and the second gear 200b can be stopped. The stop switch 360 may be configured as a limit switch as shown in FIG. 3. The stop switch 360 may be engaged and disengaged by a stop cam 370. The stop cam 370 may include a disk 371, touch protrusions 373 formed at 180-degree intervals on the periphery of the disk 371, and a rotation shaft 375 formed at the rotation center of the disk 371. The touch protrusions 373 may come into contact with a roller 363 attached to a lever 361 of the stop switch 360. The rotation shaft 375 may be inserted into the central rotation shaft of the first gear 200a through a hole 234 in the second gear bracket 232b.

[0074] Of course, as described above, power can be turned off by a mechanical mechanism, but it is also possible to stop the rotation of the first gear 200a and the second gear 200b after they have rotated 180 degrees by using an electrical circuit configuration.

[0075] In addition, when power is applied, a RED LED (not shown) around the second start switch 340 lights up, and when power is cut off, the RED LED (not shown) goes out, allowing the user to visually check the operating status.

[0076] 7 and 8 are front and rear perspective views showing the front and rear of the holder portion 400. FIG.

[0077] 3, 7 and 8, a used syringe needle separation device 10 according to an embodiment of the present invention may include a holder unit 400. The holder unit 400 may hold the first start switch 330, the second start switch 340 and the guide jig unit 500. In particular, the holder unit 400 may support the guide jig unit 500 so that it can slide left and right.

[0078] The holder part 400 may include a first holder 410. The first holder 410 may include a holder communication hole 411. The holder communication hole 411 may be connected to the insertion opening 131. The first holder 410 may have a holder support bracket 413. Four holder support brackets 413 may be formed on the left, right, top, and bottom of the first holder 410. When the first cross bar 233a and the second cross bar 233b are screwed together as shown in FIG. 2, the holder support bracket 413 may be supported by the second gear support bracket 230b by pressure from the screw heads.

[0079] The holder part 400 may include a second holder 420. The second holder 420 may be formed on the left side of the first holder 410. The second holder 420 may include a mounting base 421 on which the first start switch 330 is fastened and mounted, and a mounting groove 423 into which a portion of the first start switch 330 is fitted. The second holder 420 can hold the first start switch 330 in a dual manner.

[0080] The holder part 400 may include a third holder 430. The third holder 430 may be formed on the right side of the first holder 410. The third holder 430 may include a holding through-hole 431 that holds the second start switch 340. FIG. 9 is a front perspective view showing the guide jig unit 500. As shown in FIG.

[0081] 3 and 9, the used needle separation device 10 according to an embodiment of the present invention may include a guide jig 500. The guide jig 500 may be plate-shaped. The guide jig 500 may be supported on the rear surface of the holder 400 so as to be slidable left and right. The guide jig 500 may guide syringe-specific needle hubs between the first non-engaging receiving portion 220a and the second non-engaging receiving portion 220b. That is, the guide jig 500 may include a plurality of jig connecting holes 510 into which needle hubs are inserted according to the syringe applications. The plurality of jig connecting holes 510 may be mutually connected to the holder connecting holes 411.

[0082] The jig communication hole 510 may include a large diameter hole 511 into which the cylindrical hub of the used injection needle is inserted, a small diameter hole 513 into which only the needle of the used injection needle is inserted, and a cross hole 515 into which the cross hub of the used injection needle is inserted.

[0083] The large diameter hole 511 has a diameter of, for example, 4.6 mm, and may be used for an insulin syringe (with a very short needle) into which the needle hub of a used injection needle is inserted, as shown in Figure 13. A step 512 onto which the syringe body is attached may be formed in the large diameter hole 511. The diameter of the step 512 may be formed to be 6.6 mm.

[0084] The small diameter hole 513 has a diameter of, for example, 2.5 mm, and can be used for a general syringe into which only the needle of a used syringe is inserted, as shown in FIG.

[0085] The cross hole 514 may be used for applications where the hub of a used needle is cross-shaped, such as a luer lock syringe or a short syringe with a needle length of 10 mm or less. The cross hole 514 may only allow insertion of a cross hub.

[0086] The guide jig unit 500 may include a gripping portion 530. The gripping portion 530 may be provided on the front right side of the guide jig unit 500 so as to be positioned over the elongated hole 134. A user can grasp and slide the gripping portion 530 to adjust the jig communication hole 510 to a position appropriate for the application of used injection needles.

[0087] Meanwhile, the first holder 410 of the holder unit 400 and the guide jig unit 500 may be plate-shaped and bent in a V-shape. The V-shape allows the jig communication hole 510 to be as close as possible to the meshing tooth portions of the first gear 200a and the second gear 200b, thereby enabling quick needle separation. Therefore, the first gear bracket 232a and the second gear bracket 232b may be formed with an L-shaped step on which the V-shaped guide jig unit 300 is placed (see FIG. 3).

[0088] Furthermore, the V-shape can stably guide the sliding of the guide jig part 500 relative to the holder part 400. That is, a plurality of support guide pieces 440 can be formed on the top and bottom of the rear surface of the first holder 410. The support guide pieces 440 can support and guide the top and bottom ends of the guide jig part 500 so that it can slide left and right, as shown in Fig. 10. Furthermore, the V-shape allows the first holder 410 to support the guide jig part 500 while making surface contact with it, thereby enabling stable sliding.

[0089] 10 is a rear view of the holder section 400 and the guide jig section 500 joined together, and FIG. 11 is a front view showing the operating position of the guide jig section 500 relative to the holder section 400. As shown in FIG.

The positioning groove 610 and the positioning protrusion 630 may be formed in three stages.

[0091] That is, the first, second and third steps can determine the positions of the large diameter hole 511, the small diameter hole 513 and the cross hole 514 as shown in (a), (b) and (c) of FIG.

[0092] 8, the positioning unit 600 may include a first-stage stopper 640 and a third-stage stopper 650. Therefore, the guide jig unit 500 can slide between the first-stage stopper 640 and the third-stage stopper 650.

[0093] FIG. 15 is a cross-sectional view showing the attachment and detachment operation of the staple recovery cylinder 800 and the bottom case 110.
