Description
Technical Field
[0001] The invention relates to the technical field of medical waste treatment, in particular to a device for recovering medical waste syringes. Background Art
[0002] A syringe is a common medical device that mainly uses a needle to extract or inject gas or liquid. When in use, the syringe often comes into contact with liquids such as medicine and blood. Medical syringes are disposable medical devices and need to be disposed of as medical waste after use.
[0003] At present, syringes are divided into needles, syringes and core rods. Since the needles, syringes and core rods are made of different materials, they also need to be recycled separately during recycling. The needles and syringes on the existing syringes on the market can be assembled and separated, and there are also connected needles and syringes that are fixed and integrated. This leads to the following two situations in the recycling of discarded syringes: 1. The first type of syringe recycling process requires medical personnel to separate the needle and put it into a sharps recycling box first, and then pull the core rod out of the syringe and put it into a plastic recycling box. In this process, since the top of the needle is embedded in the liquid outlet of the syringe, when the medical personnel pulls out the needle, the medical personnel's hand needs to be close to the needle, which is dangerous. At the same time, when the connection between the needle and the syringe is 1. When the needles are too tight to be separated, medical personnel will use pliers to directly shorten the connection at the end of the needle tube to achieve the separation purpose, which is time-consuming and labor-intensive. 2. The second type of syringe recycling process requires medical personnel to clamp the needle on the recycling box, pull the needle tube horizontally, thereby breaking the needle, and then separate the needle tube and the core rod. The broken needle will leave a very small part of the connection at the top of the needle at the bottom of the needle tube. When the needle tube is put into the plastic recycling box, there is a performance part at the connection at the bottom of the needle tube that is easy to form a sharp metal object, which is a sharp weapon. In fact, this recycling method does not meet the recycling standards for discarded syringes. At the same time, it is relatively laborious and slow for medical personnel to pull out the core rod needle tube. Therefore, we proposed a medical waste syringe recycling device to solve the above problems. Summary of the invention

Figure 2 As shown, the destroying blade 24 can destroy the outer wall of the needle tube in the discarded injection original device 18, thereby preventing the needle tube of the discarded injection original device 18 from being reused and reducing safety regrets.
[0037] The functional principle of the present invention can be explained through the following operation mode: when medical personnel use the device to recycle the discarded injection device 18, they need to let the medical personnel decompose the discarded injection device 18 into the needle, the needle tube, and the core rod, put the metal needle into the sharp waste recycling box 1, and then put the needle tube and the core rod into two plastic waste recycling boxes 2 respectively;
[0038] Ask the medical staff to move the needle on the used discarded injection device 18 downward, so that the needle on the discarded injection device 18 passes through the indented cone-shaped limit block 16, the limit ring 17 and the anti-sway ring block 25 in sequence, and let the outer wall of the needle tube on the discarded injection device 18 and the inner wall of the indented cone-shaped limit block 16 slide until the bottom of the discarded injection device 18 contacts the top of the limit ring 17, so that the discarded injection device 18 stays in the feed hole 7;
[0039] Then let the medical staff press the start button in the switch button 29, such as Figure 1 As shown, the start button will start the output shaft of the servo motor 12 to rotate forward, the output shaft of the servo motor 12 will drive the bidirectional threaded rod 11 to rotate forward, the bidirectional threaded rod 11 will drive the two moving plates 13 thereon to move together toward the feeding hole 7, and the moving plate 13 will drive the clamping sleeve 21 to slide on the inner wall of the extrusion hole 14;
[0040] At the same time, the moving plate 13 will drive the cutting blade 20 to slide on the inner wall of the cutting opening 15 until the inner wall of the semicircular clamping groove 23 on the clamping sleeve 21 is attached to the outer wall of the discarded injection device 18. As the clamping sleeve 21 continues to move, the two clamping sleeves 21 will clamp the discarded injection device 18. When the clamping sleeve 21 clamps and fixes the discarded injection device 18, the medical staff will pull out the core rod of the discarded injection device 18 upwards and put the core rod into one of the plastic waste recycling boxes 2 through the feed port 8. At this time, the outer wall of the T-shaped support rod 19 slides on the inner wall of the clamping sleeve 21, so that the end of the T-shaped support rod 19 will also cause the spring 22 to compress;
[0041] After the indented conical stopper 16 clamps the discarded injection device 18, the cutting blade 20 slides on the inner wall of the cutting opening 15, and the cutting blade 20 moves toward the connection between the needle tube and the needle of the discarded injection device 18, until the two cutting blades 20 can cut off the connection between the needle tube and the needle of the discarded injection device 18, and the cut needle will fall into the sharp waste recycling box 1 through the anti-swing ring block 25. At the same time, as the T-shaped support rod 19 moves, the T-shaped support rod 19 will drive the destroying blade 24 to move on the sliding opening. When the moving destroying blade 24 contacts the needle tube of the discarded injection device 18, the destroying blade 24 will destroy the needle tube of the discarded injection device 18 as it moves, so that a cut appears on the outer wall of the needle tube of the discarded injection device 18, thereby destroying the integrity of the needle tube in the discarded injection device 18, and then the medical staff presses the reset button in the switch button 29;
[0042] The reset button will drive the output shaft of the servo motor 12 to reverse, and the output shaft of the servo motor 12 will drive the bidirectional threaded rod 11 to reverse, and the bidirectional threaded rod 11 will drive the two moving plates 13 to move away from the feed hole 7, and the moving plate 13 will drive the T-shaped support rod 19 and the cutting blade 20 to move, and the spring 22 will rebound until the moving plate 13, the T-shaped support rod 19 and the cutting blade 20 return to the initial position. At this time, the servo motor 12 is turned off, allowing the medical staff to take out the needle tube in the damaged discarded injection original device 18 from the feed hole 7, and put the needle tube in the damaged discarded injection original device 18 into another plastic waste recycling box 2, so that the recycling of the discarded injection original device 18 can be completed;
[0043] When the recyclables inside the sharp waste recycling box 1 and the plastic waste recycling box 2 need to be transported, the transport personnel hold the handle 28 and first lift up the two side protective shells 4 so that the limit bolts 6 on the side protective shells 4 slide on the inner wall of the limit ring block 5, and at the same time, the inner wall of the side protective shells 4 slides on the outer wall of the plastic waste recycling box 2, thereby removing the side protective shells 4 from the plastic waste recycling box 2. At this time, the transport personnel can lift up the middle protective shell 3 to facilitate removing the middle protective shell 3 from the sharp waste recycling box 1, so that the transport personnel can transport the recyclables in the sharp waste recycling box 1 and the plastic waste recycling box 2.
[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
