[0025] The following is a detailed description of the automatic rebound infusion needle. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0026] The following describes the present application in detail with reference to the accompanying drawings and specific implementation methods. Figure 1-7 In this embodiment, an automatic rebound infusion needle is provided, comprising: a main body 1, a receiving cavity 101 is provided inside the main body 1, an infusion tube 102 is provided inside the receiving cavity 101, an infusion needle 103 is provided at one end of the infusion tube 102, a rebound component is provided inside the receiving cavity 101, and is used to retract the infusion tube 102 into the receiving cavity 101. The rebound component comprises: a rotating shaft 2, a tape spring 201, a connecting block 202 and a transmission tube 203.

[0027] The rotating shaft 2 is rotatably connected to the axis of the accommodating chamber 101, the surface of the rotating shaft 2 is connected to the tape spring 201, the connecting block 202 is connected to one end of the tape spring 201, the transmission tube 203 is arranged on one side of the connecting block 202, a positioning plate 4 is provided on one side of the body 1, a through hole 401 is provided on one side of the positioning plate 4, a rotating block 402 is provided inside the through hole 401, the top and bottom of the rotating block 402 are connected to the slider 403, and the through hole 401 is provided with a matching slider 403. The sliding groove 404 is connected to the rotating block 402, one side of the rotating block 402 is connected to two positioning rods 405, one side of the rotating shaft 2 is provided with a positioning hole 406 that matches the positioning rod 405, one side of the positioning plate 4 is connected to two connecting rods 407, one side of the main body 1 is provided with a connecting hole 408 that matches the connecting rod 407, and a fixing ring is connected to the surface of the connecting rod 407 and the inside of the connecting hole 408. One end of the infusion tube 102 is connected to the connecting block 202, and the transmission tube 203 is connected to the connecting block 202.

[0028] When it is necessary to adjust the length of the infusion tube 102, you can grab the infusion needle 103 and pull it outwards, so that the infusion needle 103 will move with the infusion tube 102 when it moves, and the infusion tube 102 will move with the connecting block 202 when it moves, and the connecting block 202 will move with the tape spring 201 when it moves, so that the tape spring 201 begins to tighten, allowing more of the infusion tube 102 to be exposed outside the body 1. At this time, you can grab the exposed infusion tube 102 and the top part of the body 1 with your hands to prevent the exposed infusion tube 102 from retracting. After the adjustment is completed, you can align the sliding groove 404 on the inner side of the positioning plate 4 with the slider 403 with your other hand and insert it. After alignment, place the positioning plate 4 on one side of the body 1. At the same time, the connecting rod 407 is allowed to enter the connecting hole 408, so that the positioning plate 4 cannot rotate through the cooperation between the connecting rod 407 and the connecting hole 408, thereby preventing the rotating block 402 from rotating, and then fixing the tape spring 201 through the positioning plate 4, so that the tape spring 201 cannot be restored, and the infusion tube 102 that has left the accommodating chamber 101 cannot return to the accommodating chamber 101. To restore the tape spring 201, the positioning plate 4 can be grasped, and after grasping, the positioning plate 4 can be pulled outward to make the slider 403 leave the slide groove 404, thereby releasing the limit on the rotating block 402, allowing the rotating shaft 2 to start rotating, and allowing the infusion tube 102 to return to the accommodating chamber 101.

[0029] Among them, a storage groove 3 that cooperates with the infusion needle 103 is opened on one side of the main body 1, and a fixing groove 301 that cooperates with the infusion tube 102 is opened inside the storage groove 3.

[0030] When the infusion needle 103 is to be used, the baffle 302 is grasped and then pulled away from the body 1, so that the baffle 302 moves with the fixing rod 303, and the fixing rod 303 moves with the limiting ring 305, and the limiting ring 305 gradually leaves the limiting groove 306 when moving, thereby releasing the restriction on the fixing rod 303, so that the baffle 302 can be away from the body 1, exposing the storage groove 3, so that the infusion needle 103 can be taken out for use. When the infusion needle 103 is to be stored, the infusion needle 103 can be placed in the storage groove 3, and the fixing rod 303 is aligned with the fixing hole 304 after placement. After alignment, push the baffle 302 toward the direction of the body 1, so that the fixing rod 303 enters the fixing hole 304, and the limiting ring 305 enters the limiting groove 306, so as to limit and fix the fixing rod 303, and then fix the baffle 302 to protect the infusion needle 103. A pressing button is installed on the outside of the bottom of the baffle 302, and a buckle head adapted to the pressing button is installed on the outside of the body 1. When the baffle 302 is pulled outward, the side of the baffle 302 with the pressing button is aligned with the buckle head and fastened to fix the baffle 302 on the outside of the body 1. It does not block the storage slot 3 and can also prevent the baffle 302 from being lost, achieving the purpose of taking and using it.

[0031] The specific workflow is:

[0032] When the infusion needle 103 is to be used, the baffle 302 is grasped and then pulled away from the body 1, so that the baffle 302 moves with the fixing rod 303, and the fixing rod 303 moves with the limiting ring 305, and the limiting ring 305 gradually leaves the limiting groove 306 when moving, thereby releasing the limit of the fixing rod 303, so that the baffle 302 can be away from the body 1, exposing the receiving groove 3, and the infusion needle 103 can be inserted. 3 is taken out for use. When the infusion needle 103 is to be stored, the infusion needle 103 can be placed in the storage slot 3. After placement, the fixing rod 303 is aligned with the fixing hole 304. After alignment, the baffle 302 is pushed toward the body 1 so that the fixing rod 303 enters the fixing hole 304, and the limiting ring 305 enters the limiting groove 306. In this way, the fixing rod 303 is limited and fixed, and the baffle 302 is fixed to protect the infusion needle 103.

[0033] When it is necessary to adjust the length of the infusion tube 102, you can grab the infusion needle 103 and pull it outwards, so that the infusion needle 103 will move with the infusion tube 102 when it moves, and the infusion tube 102 will move with the connecting block 202 when it moves, and the connecting block 202 will move with the tape spring 201 when it moves, so that the tape spring 201 begins to tighten, allowing more of the infusion tube 102 to be exposed outside the body 1. At this time, you can grab the exposed infusion tube 102 and the top part of the body 1 with your hands to prevent the exposed infusion tube 102 from retracting. After the adjustment is completed, you can align the sliding groove 404 on the inner side of the positioning plate 4 with the slider 403 with your other hand and insert it. After alignment, place the positioning plate 4 on one side of the body 1. At the same time, the connecting rod 407 is allowed to enter the connecting hole 408, so that the positioning plate 4 cannot rotate through the cooperation between the connecting rod 407 and the connecting hole 408, thereby preventing the rotating block 402 from rotating, and then fixing the tape spring 201 through the positioning plate 4, so that the tape spring 201 cannot be restored, and the infusion tube 102 that has left the accommodating chamber 101 cannot return to the accommodating chamber 101. To restore the tape spring 201, the positioning plate 4 can be grasped, and after grasping, the positioning plate 4 can be pulled outward to make the slider 403 leave the slide groove 404, thereby releasing the limit on the rotating block 402, allowing the rotating shaft 2 to start rotating, and allowing the infusion tube 102 to return to the accommodating chamber 101.
