Description

Technical Field

[0001] This utility model belongs to the field of dialysis indwelling needle technology, specifically a novel dialysis indwelling needle. Background Technology

[0002] Dialysis can be divided into peritoneal dialysis and hemodialysis. Peritoneal dialysis uses the peritoneum as a membrane, periodically injecting peritoneal fluid and then promptly draining the replaced waste fluid. Hemodialysis involves artificially filtering blood and returning the filtered clean blood back into the patient's body to improve their quality of life. An indwelling needle is required during hemodialysis.

[0003] The existing indwelling needles are not securely fixed during use. When the patient moves, the needle can easily shift. If the needle punctures a blood vessel, the indwelling needle needs to be pulled out and reinserted, causing the patient to suffer considerable pain. Summary of the Invention

[0004] The purpose of this invention is to provide a novel dialysis indwelling needle to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a novel dialysis indwelling needle is provided, including a fixing clamp, a needle tip is movably connected to the inner side of the fixing clamp, a needle cap is placed on the outer side of the needle tip, a connecting tube is fixedly connected to the left end of the needle tip, a connector is fixedly connected to the left end of the connecting tube, a single-hand clamp is placed on the outer side of the connecting tube, the needle tip includes a rotating post movably connected to the inner side of the fixing clamp, a connecting cylinder is fixedly connected between the rotating posts, a fixing cylinder is fixedly connected to the right side of the connecting cylinder, a groove is provided on the outer side of the fixing cylinder, and a needle body is fixedly connected to the middle of the right side of the connecting cylinder.

[0026] Reference Figures 1 to 7 The present invention will now be described. A novel dialysis indwelling needle includes a fixing clip 1, a needle 2 movably connected to the inner side of the fixing clip 1, a needle cap 3 placed on the outer side of the needle 2, a connecting tube 4 fixedly connected to the left end of the needle 2, a connector 6 fixedly connected to the left end of the connecting tube 4, and a single-hand clamp 5 placed on the outer side of the connecting tube 4. The needle 2 includes a rotating column 202 movably connected to the inner side of the fixing clip 1. The rotating column 202 can rotate around a rotating groove 105 on the inner side of the fixing clip 1. A connecting cylinder 201 is fixedly connected between the rotating columns 202. A fixing cylinder 203 is fixedly connected to the right side of the connecting cylinder 201. A groove 204 is provided on the outer side of the fixing cylinder 203. The groove 204 is used for the needle cap 3 to be inserted. By pressing the needle cap 3 into the groove 204, the fixing sleeve 302 can deform and enter the groove 204, making the needle cap 3 more firmly fixed. A needle body 205 is fixedly connected to the middle of the right side of the connecting cylinder 201. The needle body 205 is used to insert into the patient's body.

[0027] Furthermore, the fixing clamp 1 includes a lower clamping plate 101 and an upper clamping plate 104. A fixing block 102 is fixedly connected to the top of the lower clamping plate 101, and a fixing shaft 106 is fixedly connected to the inner side of the fixing block 102. A connecting block 103 is fixedly connected to the lower part of the upper clamping plate 104. The connecting block 103 is movably connected to the fixing shaft 106 and can rotate outside the fixing shaft 106, thereby allowing the upper clamping plate 104 and the lower clamping plate 101 to rotate relative to each other. A rotating groove 105 is provided on the inner side of the upper clamping plate 104 for the rotation of the rotating column 202. A first spring 107 is fixedly connected between the lower clamping plate 101 and the upper clamping plate 104. By moving the lower clamping plate 101 and the upper clamping plate 104 inward... The compression allows it to rotate relative to the first spring 107, which in turn compresses the first spring 107. The compression of the first spring 107 generates a reverse force, and it will return to its original position after the upper clamp 104 and lower clamp 101 are released, so as to clamp the object and fix the position of the fixing clamp 1, thereby making the position of the needle 2 more stable and preventing the needle body 205 from moving due to the movement of the patient. The upper clamp 104 is made of PVC. Since the opening at the connection between the upper clamp 104 and the needle 2 is relatively long, when the connection between the upper clamp 104 and the needle 2 is compressed, the upper clamp 104 will deform in the middle, thereby applying pressure to the needle 2 and ensuring that the position of the needle 2 is fixed.

[0028] Furthermore, the rotating column 202 includes a column 2021 fixedly connected to the outside of the connecting cylinder 201. A movable block 2023 is movably connected inside the column 2021, allowing the movable block 2023 to move within the column 2021. A second spring 2022 is fixedly connected between the column 2021 and the movable block 2023. A top column 2024 is fixedly connected to the side of the movable block 2023 away from the second spring 2022. Under the action of the second spring 2022, the top column 2024 can firmly press against the upper clamping plate 104, thereby preventing the rotating column 202 from rotating and ensuring a more stable position for the needle 2. During use, the needle 2 can be rotated between the upper clamping plates 104 by moving it. The needle 2 can be adjusted to a suitable position, and then the two sides of the upper rotating column 202 of the upper clamp 104 can be pinched to make the upper clamp 104 firmly clamp the needle 2, preventing the needle 2 from rotating and ensuring that the needle 2 can be stably inserted into the patient's body. After insertion, the needle 2 can be fixed with infusion tape first, and then the upper clamp 104 can be made to fit the patient's skin. Then, the lower clamp 101 can be turned so that the infusion tape can fix both ends of the upper clamp 104. Then, the lower clamp 101 can be released to clamp it on the infusion tape, making it more firmly fixed, thereby making the position of the needle 2 more stable and preventing the connecting tube 4 from moving due to pulling or the patient's movement.

[0029] Furthermore, the needle cap 3 includes a cap body 301 placed outside the needle head 2, and a fixing sleeve 302 is fixedly connected to the left side of the inner side of the cap body 301. The fixing sleeve 302 is made of rubber and can be deformed by compression, so that it can be inserted into the groove 204, so that the needle cap 3 can be stably fixed on the needle head 2.

[0030] Furthermore, the single-hand clamp 5 includes an upper clamping strip 504 placed on the outside of the connecting pipe 4. The lower part of the upper clamping strip 504 is provided with a pipe groove 505 for the connecting pipe 4 to pass through. A connecting plate 501 is fixedly connected to the rear side of the upper clamping strip 504. A lower clamping strip 503 is fixedly connected to the lower part of the front side of the connecting plate 501. A pressure block 502 is fixedly connected to the top of the lower clamping strip 503. The single-hand clamp 5 is made of PVC. By applying pressure to the upper clamping strip 504 and the lower clamping strip 503 towards the middle, the single-hand clamp 5 deforms towards the middle, so that the pressure block 502 can squeeze the connecting pipe 4 in the pipe groove 505. By squeezing, the connecting pipe 4 is closed. After releasing, the pressure block 502 returns to its original position, so that the connecting pipe 4 is connected, which facilitates the control of the opening and closing of the connecting pipe 4.

[0031] Furthermore, the connector 6 includes a first connector 601 fixedly connected to the left end of the connecting tube 4, a plastic needle 602 fixedly connected to the left side of the first connector 601, a sealing cap 603 fixedly connected to the outside of the first connector 601, and a second connector 604 fixedly connected to the outside of the first connector 601. The connector 6 is used to connect a syringe, aspirate blood, or administer intravenous medication in an emergency.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
