AI Technical Summary
Existing waste injection needle separation devices cannot adapt to different needle lengths and needle hub shapes, resulting in low separation efficiency, especially when the adhesion strength between the needle hub and the needle is high, it is difficult to separate, and different needle hub types need to be handled separately.
A waste injection needle separation device was designed. It uses a specific meshing tooth shape formed on the gear and accommodates the non-meshing part. It achieves rapid separation through 180-degree rotation, uses high-frequency induction heating to reduce the strength of the adhesive, and combines a guide clamp and a start button to improve operational convenience.
The rapid separation of needles is achieved, which can significantly shorten the separation time and reduce power consumption regardless of the needle length and needle hub shape. It can also effectively separate needle hubs with high bonding strength and improve separation efficiency.

Abstract
Description
Technical Field
[0001] The present invention relates to a waste injection needle separation device having a driving rotation meshing tooth shape formed along one side of the circumference and a non-meshing portion for accommodating non-injection needles and a separation meshing tooth shape for waste injection needles formed along the other side of the circumference. Background Art
[0002] There are many types of syringes depending on their usage, such as ordinary syringes, syringes for blood collection, syringes for insulin, catheters for intravenous injection, vacuum needles for blood collection, etc.
[0003] In addition, the needle hub of the syringe is integrated at the end of the syringe body, inserted, or Luer lock type.
[0004] In addition, reference Figure 16 , when the needle 3 is fixed to the hub 2, the syringe needle hub 1 inserts only a portion of one side of the needle 3 into the hub 2, and this portion may be coated with an adhesive.
[0005] Furthermore, the length or thickness of the needle 3 of the needle hub 1 may also be different.
[0006] In addition, depending on the type of syringe, the diameter of the hub 2 can be a large diameter, a small diameter, etc., and its shape can also be a cylinder, a cross, etc.
[0007] For example, Korean Patent Publication No. 10-1588170 discloses a device for separating used syringe needles.
[0008] The automatic needle sorting device disclosed in the patent document pulls the needle that has passed through a pair of rotating needle separation gears back into a pair of needle processing gears to separate it from the syringe.
[0009] However, the automatic needle sorting device in the patent document has the following problems.
[0010] First, as described in the patent document, when the needle length is appropriate, since the needle tip is pulled from the state of contacting the meshing portion of the needle processing gear, a working time as long as the needle length is required.
[0011] Secondly, when the needle of an insulin syringe is very short, although it enters the needle penetration hole, the needle tip does not contact the meshing portion of the needle handling gear, which may cause the needle to be unable to be separated.
[0012] Third, when the needle is very long, even if the needle tip hits the meshing portion of the needle handling gear, the user needs to hold the syringe body to handle it, which is very inconvenient and may take a longer time to separate the needle.
[0013] Fourth, depending on the diameter or shape of the needle hub, the needle hub may not be mounted on the syringe mounting portion.
[0014] This existing automatic needle sorting device cannot be processed according to the type of needle and needle hub, and therefore must be equipped with a separate processing device.
[0015] On the other hand, the blood collection needle or the catheter needle has a blood collection needle hub 5, such as Figure 24 As shown, the needle 7 passes through the hub 6, and the hub 6 and the needle 7 are fixed with adhesive.
[0016] Since the needle hub 5 for blood collection or the needle hub for catheter is fixed in the case of puncture, this is different from the conventional syringe in which only a part of the needle tip is inserted (see Figure 16 ) is different, the adhesive bonding strength is so high that the needle cannot be pulled out and only the Figure 25 The lower portion of the needle 7' is shown cut off.
[0017] Furthermore, since the needle 7 passes through the hub 6, the needle 7 is blocked and the hub 6 cannot be cut alone with a knife or the like.
[0018] Therefore, a needle hub 5 used only for blood sampling or a needle hub for an IV catheter can only be discarded without the needle 7 ′ being completely removed.
[0019]

[0064] Example Figure 1 1 is a perspective view of a waste injection needle separation device 10 according to a preferred embodiment of the present invention. Figure 2 is to remove Figure 1 A perspective view of the cover housing 130, Figure 3 yes Figure 2 A three-dimensional diagram of the main parts of Figure 4 is a top view of the bottom case 110, Figure 5 It is a perspective view of the appearance of the cover housing 130 .
[0065] refer to Figure 1 The waste injection needle separating device 10 according to the embodiment of the present invention may include a housing 100 . The housing 100 may include a plate-shaped bottom housing 110 and a barrel-shaped cover housing 130 .
[0066] like Figure 2 As shown, the bottom case 110 can fix or support various components. Figure 3 and Figure 4As shown, the bottom housing 110 may include a discharge hole 111 located at the front center. The discharge hole 111 allows the separated needles to fall into the needle collecting barrel 900. A sloped surface 112 may be formed in front of the discharge hole 111, sloping downward toward the discharge hole 111. When the separated needles rebound, the sloped surface 112 may guide them to slide toward the discharge hole 111.
[0067] like Figure 4 As shown, the bottom shell 110 may include an additional discharge hole 113 located at the center of the rear portion. The additional discharge hole 113 may be manually separated by a needle. At the rear of the additional discharge hole 113, an additional inclined surface 114 may be formed that is inclined downward toward the additional discharge hole 113, similar to the inclined surface 112. Figure 2 and Figure 3 As shown, a blocking wall 115 covering the left, right, and front sides of the additional discharge hole 113 and the additional inclined surface 114 can be formed to protrude upward. The blocking wall 115 can be a U-shaped column. Even if the manually separated needle bounces up, the blocking wall 115 can make it fall into the additional discharge hole 113.
[0068] like Figure 4 As shown, the bottom housing 110 may include a light irradiation through-hole 116. The light irradiation through-hole 116 may be arranged between the drain hole 111 and the additional drain hole 113. The light irradiation through-hole 116 may be a passage for light from the sterilization lamp 700 to irradiate the needle collection tube 900. When powered on, the sterilization lamp 700 may illuminate the UVC-LED to sterilize the separation needles accumulated in the needle collection tube 900.
[0069] like Figure 5 As shown, the cover housing 130 may be in the shape of a hexahedron covering the upper portion of the bottom case 110. The cover housing 130 may include a front plate 130a, a rear plate 130b, a left plate 130c, a right plate 130d, and a top plate 130e.
[0070] The edge portions of the front plate 130a and the top plate 130e may be formed by an inclined plate 130f pressed at an angle of 45 degrees.
[0071] An insertion port 131 is formed in the inclined plate 130f. The insertion port 131 allows the needle hub of the waste injection needle to be inserted through the insertion port 131. A step 132 may be formed on the circumference of the insertion port 131, and the main body of the waste syringe is stuck on the step 132.
[0072] A second start switch 340 is provided in the tilt plate 130f.
[0073] The inclined plate 130 f may form a long hole 134 in which a gripping portion 530 described later is slidably disposed.
[0074] A through hole 138 may be formed on the side where the front plate 130a, the inclined plate 130f, and the top plate 130f of the housing intersect. The through hole 138 may be vertically adjacent to the insertion port 131. A start button 350 that contacts the first start switch 330 may be disposed in the through hole 138.
[0075] A through-hole 135 can be formed in the top plate 130e, into which the display window 810 of the counter 800 will be placed. In the counter 800, a rectangular barrel can be mounted on the top surface of the sterilization lamp 700. This rectangular barrel of the counter 800 can cause the separated needles to rebound, collide, and fall into the discharge hole 111. A metal plate (not shown) can be placed where the separated needles collide to prevent scratches. Furthermore, if the needles are very long, for example, longer than 5 cm, the needle tips will contact the metal plate (not shown), directing the separated needle tips toward the floor, allowing them to be reliably collected in the needle collection barrel 900. Furthermore, the metal plate (not shown) is preferably made of stainless steel, which will not rust due to blood or medication on the needle tips. The pulse counter 800 can display a number on the display window 810 that increments as the needles are energized and disconnected.
[0076] A manual needle detaching hole 136 and a manual knife detaching hole 138 may be formed in top plate 130e. These holes may be formed directly above barrier wall 115. Manual needle detaching hole 136 allows for detaching needle 3 by inserting needle hub 1 from above, pulling it sideways, and then bending it. Manual knife detaching hole 138 allows for detaching a scalpel when the scalpel's fixed portion is inserted or removed with the fixed portion facing downward.
[0077] A groove 137 may be formed on the top plate 130e for temporarily placing a waste syringe without a detached needle.
[0078] Figure 6 It is enlarged to show Figure 3 A three-dimensional view of the first gear 200a and the second gear 200b.
[0079] refer to Figure 6 The waste injection 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 and pulling out waste injection needles. The first gear 200a and the second gear 200b may be a pair of spur gears.
[0080] The first gear 200a and the second gear 200b, which are the core of the present invention, can include a first driving rotation meshing tooth profile 210a and a second driving rotation meshing tooth profile 210b formed along the entire circumference of one side. The first driving rotation meshing tooth profile 210a and the second driving rotation meshing tooth profile 210b can mesh and rotate the first gear 200a and the second gear 200b. In this embodiment, the first gear 200a serves as the driving gear and the second gear 200b serves as the driven gear, but the opposite functions can also be used.
[0081] Furthermore, the first gear 200a and the second gear 200b, which are the core of the present invention, can include a first non-meshing portion 220a and a second non-meshing portion 220b, and a first and a second separating meshing tooth profiles 225a and 225b, formed along the circumference of the other side. The first and second non-meshing portions 220a and 220b can hold the waste injection needle 3 as close as possible to the first and second separating meshing tooth profiles 225a and 225b. The first and second separating meshing tooth profiles 225a and 225b can engage and disengage with the stored waste needle 3. The first and second non-meshing portions 220a and 220b can be formed only on one side, or, as shown in this embodiment, at 180-degree intervals. Furthermore, a gap between the first and second non-meshing portions 220a and 220b can be provided opposite the insertion port 131.
[0082] In this embodiment, the number of the first driving rotating meshing tooth profile 210a and the second driving rotating meshing tooth profile 210b is 30 each, and the first accommodating non-meshing portion 220a and the second accommodating non-meshing portion 220b each have six teeth removed from both sides, and nine of the first separating meshing tooth profile 225a and the second separating meshing tooth profile 225b can separate the waste needle 3.
[0083] By forming the first non-engaging portion 220a and the second non-engaging portion 220b, when the needle has a normal length, as shown in FIG. Figure 12 As shown, the needle can be inserted into the gap between the first non-meshing portion 220a and the second non-meshing portion 220b at most, and the separation time can be very short. If the length of the needle is very short, such as Figure 13 As shown, the needle hub 2 can be inserted into the gap between the first accommodating non-engaging portion 220a and the second accommodating non-engaging portion 220b.
[0084] like Figure 2 and Figure 3 As shown, the first gear 200a and the second gear 200b are rotatably supported on the first gear support bracket 230a and the second gear support bracket 230b. The first gear support bracket 230a and the second gear support bracket 230b can be a pair.
[0085] The first and second gear supporting brackets 230a and 230b may include first and second leg brackets 231a and 231b connected to the bottom case 110 and first and second gear brackets 232a and 232b rotatably supporting the first and second gears 200a and 200b.
[0086] 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. Both ends of the first rotating shaft (not shown) are rotatably supported between the first gear bracket 232a and the second gear bracket 232b. The first rotating shaft (not shown) may serve as the driving shaft of the first gear 200a.
[0087] The second gear 200b can be rotatably supported between the first gear bracket 232a and the second gear bracket 232b via a second rotating shaft (not shown). The second rotating shaft (not shown) can be formed by a bearing (not shown). The bearing (not shown) can be a driven shaft of the second gear 200b.
[0088] 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 for supporting the first gear bracket 232a and the second gear bracket 232b. The first cross bars 233a and the second cross bars 233b may be fastened and fixed by fastening elements.
[0089] The first gear 200 a and the second gear 200 b are stably held by the first crossbar 233 a and the second crossbar 233 b without being deformed, thereby preventing the second gear 200 b from being separated during the separation process of the waste injection needle 3 .
[0090] refer to Figure 3 , the first rotation axis and the second rotation axis (not shown) of the first gear 200a and the second gear 200b are arranged in parallel at the bottom and the top, and at least the first rotation axis (not shown) can be located in front relative to the second rotation axis (not shown). Figure 14 As shown, the staggered arrangement of the first rotation axis and the second rotation axis (not shown) allows the needle 3 to automatically separate and fall due to the weight of the waste syringe when the waste syringe is inserted at a 45-degree angle and placed in the insertion port 131 .
[0091] Reference Figure 2 and Figure 3 The waste injection needle separating device 10 according to the embodiment of the present invention may include a driving unit 300. The driving unit 300 may transmit a rotational force to the first gear 200a.
[0092] The driving unit 300 may include a motor 310. As in the present embodiment, the motor 310 may be powered by a battery (not shown) installed in the bottom housing 110. Of course, an external power source may also be received.
[0093] The driving unit 300 may include a reduction gear unit 320. The reduction gear unit 320 may be supported on 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. The output shaft (not shown) of the reduction gear unit 320 may be connected to the rotation shaft (not shown) of the first gear 200a. Of course, the reduction gear unit 320 and the motor 310 may be placed and supported on the bottom housing 110.
[0094] When the first start switch 330 or the second start switch 340 is actuated, the driving portion 300 may be energized to drive the first gear 200 a and the second gear 200 b .
[0095] The first start switch 330 may be a limit switch. A start button 350 may be mounted on the lever of the first start switch 330. Figure 14 As shown in FIG. 1 , the start button 350 can be operated by inserting the waste syringe into the insertion port 131 and then pulling it to the side and pressing it. Figure 12 As shown in FIG. 1 a, the first activation switch 330 can be applied to the case where only the needle 3 is inserted into the small-diameter hole 513. Since the needle 3 can be pulled and controlled laterally, the first activation switch 330 can be operated by the syringe body.
[0096] The user can directly press the second start switch 340 to apply power. The second start switch 340 can be a push button switch. Figure 13 As shown in FIG. 1 a, the second start switch 340 can be applied when the hub 2 is inserted into the large-diameter hole 513 or the cross hole 514. Since the hub 2 is completely inserted into the large-diameter hole 513 or the cross hole 514 and is difficult to bend laterally like the needle 3, in some cases, the start button 350 cannot be operated by the syringe body, so that the user can press the second start switch 340.
[0097] When the power supply of the driving unit 300 is cut off by the stop switch 360, the driving of the first gear 200a and the second gear 200b can be stopped. Figure 3As shown, the stop switch 360 may be a limit switch. The stop switch 360 may be disconnected by a stop cam 370. The stop cam 370 may include a disk 371, contact protrusions 373 formed at 180-degree intervals around the disk 371, and a rotation shaft 375 formed at the rotation center of the disk 371. The contact protrusions 373 may contact a roller 363 mounted on the lever 361 of the stop switch 360. The rotation shaft 375 may be inserted into the central rotation axis of the first gear 200a through the hole 234 in the second gear bracket 232b.
[0098] Of course, as described above, the power supply can be turned off by a mechanical mechanism, but it can also be stopped by a circuit configuration after the first gear 200a and the second gear 200b rotate 180 degrees.
[0099] Furthermore, 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) turns off, and the user can confirm the operating status with the naked eye.
[0100] Figure 7 and Figure 8 1 and 2 are front and rear perspective views showing the front and rear of the holder segment 400 .
[0101] Reference Figure 3 、 Figure 7 and Figure 8 The waste injection needle separating device 10 according to an embodiment of the present invention may include a holder 400. The holder 400 may hold the first and second start switches 330 and 340 and the guide clamp 500. In particular, the holder 400 may support the guide clamp 500 so as to slide left and right.
[0102] The holder portion 400 may include a first holder 410. The first holder 410 may include a holder through hole 411. The holder through hole 411 may be in communication with the insertion port 131. A holder support bracket 413 may be formed on the first holder 410. Four holder support brackets 413 may be formed on the left side, right side, top, and bottom of the first holder 410.

[0106] refer to Figure 3 and Figure 9 The waste injection needle separation device 10 according to an embodiment of the present invention may include a guide clamp portion 500. The guide clamp portion 500 may be plate-shaped. The guide clamp portion 500 may be supported by the retainer portion 400 so as to slide left and right from the back side. Furthermore, the guide clamp portion 500 may guide the syringe needle hub between the first non-engaging portion 220a and the second non-engaging portion 220b. Specifically, the guide clamp portion 500 may include a plurality of clamp through-holes 510 into which the syringe needle hub is inserted. The plurality of clamp through-holes 510 may be connected to the retainer through-hole 411.
[0107] The clamp through hole 510 may include a large diameter hole 511 for inserting a cylindrical hub of a waste needle, and a small diameter hole 513 for inserting only a needle of the waste needle, that is, a cross hole 515 for inserting a cross hub of the waste needle.
[0108] like Figure 13 As shown, large-diameter hole 511 may be used to insert the needle hub of a used insulin syringe. The needle length is very short, for example, the hole diameter is 4.6 mm. A step 512 may be formed in large-diameter hole 511 for the syringe body to be stuck. The diameter of step 512 may be 6.6 mm.
[0109] like Figure 12 As shown, the diameter of the small-diameter hole 513 is, for example, 2.5 mm, and can be used for a normal syringe into which only the needle of a waste injection needle is inserted.
[0110] The cross hole 514 can be used for a waste syringe whose hub is cross-shaped, such as a Luer Lock syringe, or a short syringe with a needle length less than 10 mm. The cross hole 514 only allows the insertion of a cross hub.
[0111] The guide clamp portion 500 may include a gripping portion 530. The gripping portion 530 may be mounted on the front right side of the guide clamp portion 500 so as to be positioned over the long hole 134.

[0112] At the same time, the first retainer 410 of the retainer portion 400 and the guide clamp portion 500 can be in the shape of a plate bent into a V shape. The V-shaped shape allows the clamp through hole 510 to be positioned as close as possible to the meshing toothed portion of the first gear 200a and the second gear 200b to quickly separate the needle. Therefore, an L-shaped step can be formed in the first gear bracket 232a and the second gear bracket 232b, and the V-shaped guide clamp portion 300 is installed on the L-shaped step (see Figure 3 ).
[0113] In addition, the V-shape can stably guide the guide clamp portion 500 to slide relative to the holder portion 400. That is, a plurality of support guide pieces 440 can be formed on the top and bottom of the back surface of the first holder 410. Figure 10 As shown, the support guide piece 440 can guide while supporting the upper and lower ends of the guide clamp part 500 in a left-right sliding manner. In addition, since the first retainer 410 is in face-to-face contact with the guide clamp part 500, the V-shaped shape plays a supporting role, so stable sliding can be achieved.
