[0004] However, when removing the needle, the above device needs to fix the syringe by hand and then remove the needle, which may cause residual medicine to drip onto the operator's hands and corrode the skin. In addition, when removing the needle, the above device can only remove a straight needle like a 2 ml needle, and a 20 ml spiral needle cannot be removed by the above device. Utility Model Content

[0005] The problem to be solved by the present invention is to overcome the disadvantages of the prior art that the needle needs to be removed by holding the syringe in a handheld manner, which easily causes residual medicine to drip onto the operator's hands and corrode the skin, and the above device can only remove a straight needle like a 2 ml needle when removing the needle, and a 20 ml spiral needle cannot be removed by the above device.

[0006] A needle separation device is proposed, comprising a barrel body and a barrel cover, and also comprising a fixed box, an electric clamp for clamping a syringe, a clamping assembly for clamping the needle and a rotating device for rotating the needle, wherein the barrel cover is threadedly connected to the top of the barrel cover, the fixed box is arranged inside the barrel body and fixedly connected to the barrel cover, the electric clamp is transversely arranged inside the fixed box and fixedly connected to the top plate of the fixed box, the rotating device is arranged inside the fixed box and fixedly connected to the bottom plate of the fixed box, the clamping assembly is arranged inside the fixed box and fixedly connected to the top of the rotating device, and the clamping assembly is located directly below the electric clamp.

[0007] In the technical solution of the utility model, when it is necessary to remove the needle, after the syringe is inserted into the interior of the fixing component, the electric clamp is started, and the electric clamp will clamp the barrel of the syringe after tightening, and then the clamping component will clamp the needle and rotate it to remove the needle. Because the electric clamp has clamped the barrel of the syringe, the syringe will not rotate with the needle during the process of rotating the clamping component to remove the needle. After the clamping component removes the needle, the syringe can be taken out of the fixing component by hand, and the residual medicine liquid inside the syringe will also drip into the barrel body and will not splash onto the hands of medical staff. This is used to solve the problem mentioned in the technical background that in the process of removing the needle, the syringe needs to be fixed by hand before the needle can be removed, which easily causes residual medicine to drip onto the operator's hands and corrode the skin.

[0008] After the jacket inside the clamping assembly clamps the needle, the rotating device will drive the clamping assembly to rotate. During the rotation of the clamping assembly, the electric push rod will also drive the jacket to fall slowly. Because the jacket has clamped the needle, the needle will be driven to rotate and fall together during the falling and rotation of the jacket. The 20 ml spiral needle will also spiral out of the syringe during the rotation. Similarly, the 2 ml straight needle can be removed from the syringe in the same way, so as to solve the problem mentioned in the technical background that the above-mentioned device can only remove the 2 ml straight needle when removing the needle, and the 20 ml spiral needle cannot be removed by the above-mentioned device.

[0009] Preferably, the technical solution of the utility model is that the rotating device includes a first motor, a main gear, a sleeve and a sub-gear. The first motor is vertically fixedly connected to the bottom plate of the fixed box, the main gear is fixedly connected to the output end of the first motor, the sleeve is located on one side of the first motor and is also vertically connected to the bottom plate of the fixed box, the top of the sleeve is rotatably connected to the sub-gear, the clamping assembly is fixedly connected to the sub-gear, and the sub-gear and the main gear are meshed with each other. When the first motor drives the main gear to rotate, the main gear will drive the sub-gear to rotate together, and when the sub-gear rotates, it will drive the clamping assembly to rotate together, and when the clamping assembly rotates, it will drive the needle to rotate together, and the needle will also spirally withdraw from the syringe during the rotation.

[0010] In the preferred embodiment of the technical solution of the utility model, the clamping assembly includes a shell, a fixed assembly, a bearing seat, a slider, an electric push rod, a sleeve, a guide rod, a lead screw and a second motor. The shell is fixedly connected to the top of the sub-gear, and the top of the shell is vertically connected to the fixed assembly. Two groups of bearing seats are arranged inside the shell according to the length direction of the shell, and the two groups of bearing seats are respectively arranged on both sides of the fixed assembly and the two groups of bearing seats are fixedly connected to the bottom plate inside the shell. Two groups of sliders are horizontally arranged inside the shell, and the two groups of sliders are respectively located at both ends of the fixed assembly. The middle position of each group of sliders is vertically fixedly connected to an electric push rod, and the output end of each electric push rod is fixedly connected to a sleeve. The guide rod passes through the two groups of sliders One end of the block is fixedly connected to the bearing seat on one side of the fixed component, the other end of the lead screw passes through the two sets of sliders and is rotatably connected to the bearing seat on the other side of the fixed component, and the guide rod and the lead screw are parallel to each other. A second motor is fixedly connected to the bearing seat at one end of the lead screw, and the output end of the second motor passes through the bearing seat and is fixedly connected to the lead screw. After the needle is inserted into the interior of the clamping component, the second motor will drive the sliders at both ends of the fixed component to move synchronously in the direction of the needle through the lead screw until the jackets on the two sets of sliders completely clamp the needle, and then in the process of the sub-gear driving the clamping component to rotate, the jacket will drive the needle to rotate synchronously, and the electric push rod will also slowly move downward. At this time, the spiral needle can be removed from the syringe.

[0011] The preferred technical solution of the utility model is that the fixing assembly includes a sleeve, a buffer pad, a clamping block and a spring. The sleeve is vertically fixedly connected to the shell body, the buffer pad is arranged inside the sleeve and below the clamping block, and two clamping blocks are vertically arranged inside the sleeve and respectively located on both sides of the sleeve. A spring is laterally arranged on one side of each clamping block, and one end of the spring is connected to the clamping block, and the other end of the spring is connected to the inner wall of the sleeve. After the syringe is vertically inserted into the fixing assembly, the bottom of the syringe will contact the buffer pad to ensure the height of the syringe, and then the clamping block will clamp the barrel of the syringe under the drive of the spring to prevent the syringe from tipping over inside the fixing assembly. Because the clamping block is connected to the sleeve through the spring, the clamping block will move laterally after being squeezed. When there is no syringe inside the filter cartridge, the two clamping blocks will contact each other under the push of the spring. Therefore, no matter what specifications of the syringe are placed in the filter cartridge, they can be clamped by the clamping block.

[0012] Preferably, the fingertips of the electric clamp are fixedly connected with rubber pads, which have great friction. Therefore, after clamping the syringe, a great friction is applied to the barrel of the syringe to prevent the syringe from rotating together with the needle during rotation. Meanwhile, the rubber pads have good elasticity to prevent the syringe from rupturing due to excessive pressure on the fingertips of the electric clamp.

[0013] Preferably, a filter cartridge is vertically inserted into the interior of the barrel body, and the clamping assembly can be loosened after the needle on the syringe is removed by the clamping assembly. The needle will fall into the filter cartridge by its own gravity, and after being disinfected with medical alcohol inside the barrel body, it will wait to be processed.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The needle is fixed by the jacket in the clamping assembly instead of the hand-held method, and then the clamping assembly is driven to rotate by the rotating device. The clamping assembly will drive the needle to rotate synchronously when rotating, until the needle is spirally removed from the syringe, and then the clamping assembly is released. The needle will fall into the filter cartridge by its own gravity and wait for processing. This method replaces the previous hand-held method of medical staff, and avoids the residual drug in the syringe dripping onto the operator's hand and corroding the medical staff's skin during the process of removing the needle. This spiral method of removing the needle is suitable for spiral needles like 20 ml. Similarly, straight needles like 2 ml can also be removed in this way. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following will be combined with the attached embodiment of the present utility model Figure 1-6 , the technical solutions in the embodiments of the utility model are described in detail.

[0024] like Figure 1-2 As shown, a needle separation device includes a barrel body 1 and a barrel cover 2, the barrel cover 2 is threadedly connected to the top of the barrel body 1, and the barrel cover 2 is also provided with a through hole at the position of the through hole on the top plate of the fixing box 3, the fixing box 3 is arranged inside the barrel body 1 and fixedly connected to the barrel cover 2, a through hole is provided on the top of the fixing box 3, and the through hole on the top plate of the fixing box 3 is perpendicular to the through hole on the barrel cover 2, after all the needles are removed by the clamping assembly 5 inside the fixing box 3 and fall into the filter cartridge 11, the barrel cover 2 can be spirally removed from the barrel body 1, and then all the needles disinfected with medical alcohol inside the barrel body 1 are taken out and processed through the filter cartridge 11, the filter cartridge 11 is vertically arranged inside the barrel body 1, and the top of the filter cartridge 11 is plug-in connected to the top of the barrel body 1, so when needed, the filter cartridge 11 can be taken out from the barrel body 1 by simply holding and moving it upward.

[0025] like Figure 3 As shown, the interior of the fixed box 3 is provided with an electric clamp 4, a clamping assembly 5, a rotating device 6 and a fixed assembly 7. The rotating device 6 is arranged in the interior of the fixed box 3 and is fixedly connected to the bottom plate of the fixed box 3. The clamping assembly 5 is located above the rotating device 6 and is fixedly connected to the sub-gear 64 of the rotating device 6. Therefore, when the sub-gear 64 rotates, the sub-gear 64 will drive the clamping assembly 5 to rotate the rod synchronously. A through hole is arranged at the center of the sub-gear 64. Through holes are opened on the top plate and the bottom plate of the shell 51 of the clamping assembly 5. The through hole at the center of the sub-gear 64 is perpendicular to the through holes on the top plate and the bottom plate of the shell 51. Therefore, after the clamping assembly 5 removes the needle, the needle is guided by the through hole at the center of the sub-gear 64 and the through holes on the top plate and the bottom plate of the shell 51 and then falls into the filter cartridge 11 to be processed. A fixing assembly 7 is arranged above the clamping assembly 5. The fixing assembly 7 is arranged inside the fixing box 3 and is vertically fixedly connected above the clamping assembly 5. Therefore, when the clamping assembly 5 is driven to rotate by the secondary gear 64, the clamping assembly 5 will also synchronously drive the fixing assembly 7 to rotate.

[0026] like Figure 3 As shown, the sleeve 71 in the fixing assembly 7 is perpendicular to the through hole on the top plate of the fixing box 3, so the syringe can fall into the sleeve 71 after passing through the through hole on the top plate of the fixing box 3. The electric clamp 4 is horizontally arranged inside the fixing box 3 and fixedly connected to the side plate of the fixing box 3, and the electric clamp 4 is located above the fixing assembly 7. After the syringe is placed in the fixing assembly 7, the electric clamp 4 can be started. After tightening, the electric clamp 4 can clamp the body of the syringe through the fingertips. The fingertips of the electric clamp 4 are fixedly connected with a rubber pad 41. The rubber pad 41 itself has a large friction force. Therefore, after the fingertips of the electric clamp 4 clamp the syringe, a large friction force will be applied to the body of the syringe through the rubber pad 41 to prevent the syringe from rotating together during the rotation of the needle. At the same time, the rubber pad 41 has good elasticity to prevent the syringe from being broken due to excessive pressure on the fingertips of the electric clamp 4.

[0027] like Figure 4 As shown, the rotating device 6 includes a first motor 61, a main gear 62, a sleeve 63 and a sub-gear 64. The first motor 61 is vertically arranged inside the fixed box 3, and the first motor 61 is fixedly connected to the bottom plate of the fixed box 3. The main gear 62 is horizontally arranged inside the fixed box 3 and fixedly connected to the output shaft of the first motor 61. Therefore, after the first motor 61 is started, the output shaft of the first motor 61 will drive the main gear 62 to rotate. The sleeve 63 is located on one side of the first motor 61 and is also vertically fixedly connected to the bottom plate of the fixed box 3. The sleeve 63 is hollow inside and is located above the through hole of the bottom plate of the fixed box 3. The sub-gear 64 is horizontally arranged inside the fixed box 3 and rotatably connected above the sleeve 63. The through hole at the center of the sub-gear 64 is perpendicular to the through hole of the sleeve 63. The main gear 62 and the sub-gear 64 are meshed with each other. Therefore, when the main gear 62 is driven to rotate by the first motor 61, the main gear 62 will synchronously drive the sub-gear 64 to rotate.

[0028] like Figure 5As shown, the clamping assembly 5 includes a housing 51, a bearing seat 52, a slider 53, an electric push rod 54, a jacket 55, a guide rod 56, a lead screw 57 and a second motor 58. The housing 51 is transversely arranged inside the fixing box 3 and fixedly connected above the secondary gear 64. Therefore, when the secondary gear 64 is driven to rotate by the main gear 62, the secondary gear 64 will also synchronously drive the housing 51 to rotate. Through holes are provided on the top plate and the bottom plate of the housing 51, and the through holes on the top plate and the bottom plate of the housing 51 are perpendicular to the through hole at the center of the secondary gear 64. The bearing seat 52 has two groups and respectively Located on both sides of the through hole of the bottom plate of the shell 51, the two bearing seats 52 are fixedly connected to the bottom plate of the shell 51, there are two groups of sliders 53 and they are respectively located at the two ends of the through hole of the bottom plate of the shell 51, the guide rod 56 passes through one end of the two groups of sliders 53 and is fixedly connected to the bearing seat 52 on one side of the through hole of the bottom plate of the shell 51, the lead screw 57 passes through the other end of the two groups of sliders 53 and is rotatably connected to the bearing seat 52 on the other side of the through hole of the bottom plate of the shell 51, and a second motor 58 is also arranged on the bearing seat 52 at one end of the lead screw 57, and the output end of the second motor 58 is fixedly connected to the lead screw 57.

[0029] like Figure 5 As shown, an electric push rod 54 is fixedly connected to the middle position of the two groups of sliders 53, and a jacket 55 is fixedly connected to the output end of the electric push rod 54. After the electric push rod 54 is started, the jacket 55 can be driven to move up and down. When in use, the electric push rod 54 can start the second motor 58 after the height of the jacket 55 is increased. The output end of the second motor 58 will drive the lead screw 57 to rotate synchronously when rotating. When the lead screw 57 rotates, the two groups of sliders 53 will be guided by the guide rod 56 and then move synchronously in the direction of the through hole of the bottom plate of the shell 51 until the jacket 55 on the two groups of sliders 53 clamps the needle. Then, when the sub-gear 64 drives the shell 51 to rotate, the shell 51 will drive the jacket 55 on the slider 53 to rotate synchronously through the guide rod 56, the lead screw 57 and the bearing seat 52. When the jacket 55 rotates, it will drive the needle to rotate. When the jacket 55 drives the needle to rotate, the electric push rod 54 will also slowly fall down to spirally remove the needle from the syringe.

[0030] like Figure 6As shown, the fixing assembly 7 includes a sleeve 71, a buffer pad 72, a clamping block 73 and a spring 74. The sleeve 71 is arranged inside the fixing box 3 and is vertically connected above the shell 51 of the clamping assembly 5. The interior of the sleeve 71 is hollow and the sleeve 71 is perpendicular to the through hole on the top plate of the shell 51. The buffer pad 72 is horizontally arranged inside the sleeve 71 and located at the bottom of the sleeve 71. A through hole is also opened in the central part of the buffer pad 72, and the through hole of the buffer pad 72 is perpendicular to the through hole on the top plate of the shell 51. There are two clamping blocks 73, which are vertically arranged inside the sleeve 71 and are respectively located on both sides of the sleeve 71. A spring 74 is arranged on one side of the two clamping blocks 73, one end of the spring 74 is connected to the clamping block 73, and the other end of the spring 74 is connected to the inner wall of the sleeve 71.

[0031] like Figure 6 As shown, when the syringe is placed in the sleeve 71, the two clamping blocks 73 will be squeezed by the outer wall of the syringe and will move laterally toward the inner wall of the sleeve 71 synchronously. The clamping blocks 73 will squeeze the spring 74 when moving, and the spring 74 will accumulate force after being squeezed. After the syringe is completely placed in the sleeve 71 and the bottom of the needle contacts the buffer pad 72, the clamping blocks 73 will clamp the outer wall of the needle under the action of the spring 74 to prevent the syringe from tipping over in the sleeve 71. After the needle is removed, the syringe can be taken out. After the syringe is taken out, the spring 74 can use the force accumulated when the clamping blocks 73 move toward the inner wall of the sleeve 71 to pop out the clamping blocks 73 in the axial direction of the sleeve 71 for reset, until the two clamping blocks 73 contact each other to complete the reset.

[0032] The movement process of this embodiment is as follows: after the syringe is vertically placed into the fixing assembly 7 inside the fixing box 3 through the through hole on the barrel cover 2, the clamping block 73 inside the fixing assembly 7 will clamp the syringe under the action of the spring 74 until the bottom of the syringe contacts the buffer pad 72 inside the sleeve 71. At this time, the needle will pass through the through hole at the center of the top plate of the shell 51 and extend into the interior of the clamping assembly 5, and then continue to start the electric clamp 4. After the electric clamp 4 clamps the syringe, start the second motor 58 inside the clamping assembly 5 to drive the lead screw 57 to rotate. When the lead screw 57 rotates, it will drive the two sets of sliders 53 to move in the direction of the needle. At this time, the electric push rod 54 will also push the jacket 55 upward to adjust the height of the jacket 55. After the jacket 55 clamps the needle, the electric push rod 54 will also stop lifting the jacket 55 upward.

[0033] After the jacket 55 clamps the needle, the first motor 61 is started to drive the main gear 62 to rotate. The main gear 62 will drive the sub-gear 64 to rotate while rotating. The sub-gear 64 will drive the needle to rotate synchronously through the jacket 55 when rotating. When the jacket 55 drives the needle to rotate, the output end of the electric push rod 54 will also drive the jacket 55 to move downward synchronously until the needle is spirally removed from the syringe. The sub-gear 64 will stop rotating. At this time, the second motor 58 drives the lead screw 57 to rotate in the reverse direction. When the two sets of sliders 53 move in the reverse direction driven by the lead screw 57, the jacket 55 will release the needle. At this time, the needle falls into the interior of the filter cartridge 11 through its own gravity and after being guided by the sleeve 63, and then the electric clamp 4 is started again to release the syringe. At this time, the syringe can be taken out of the fixing assembly 7.

[0034] The above embodiments are only for illustrating the technical idea of ​​the present utility model, and cannot be used to limit the protection scope of the present utility model. Any changes made on the basis of the technical solution in accordance with the technical idea proposed by the present utility model shall fall within the protection scope of the present utility model.
