Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an autologous repair nutrition injection needle. Background Art

[0002] The current injectable products can be roughly divided into two categories: one is absorbable hyaluronic acid, collagen, botulinum toxin, etc., which need to be injected repeatedly because they can be absorbed and metabolized; the other is some non-absorbable foreign body fillings, which have a longer time limit. Syringes are a common injectable medical device, which mainly uses a needle to extract or inject gas or liquid. Syringes can also be used in medical equipment, containers, such as some scientific instruments in chromatography that inject through rubber diaphragms. The emergence of syringes is an epoch-making revolution in the field of medical devices. The process of extracting or injecting gas or liquid with a needle is called injection.

[0003] After the injection is completed, the medical staff will cover the needle of the injection tube with the injection protective cover, and then place the injection tube on the table or in the trash can, so as to free up their hands to bandage the patient's injection site to avoid infection. However, when the medical staff covers the injection tube with the protective cover or pulls out the injection tube to move it, the needle can easily scratch and injure the skin of the medical staff or others under the pressure of emergency or external force collision. People are prone to drug infection or viral cross-infection due to the bacteria on the needle after injection.

[0004] For this reason, a self-repair nutrition injection needle is proposed. Utility Model Content

[0027] like Figures 1 to 2 As shown, an autologous repair nutrition injection needle comprises an outer needle tube 1 storing medicine, a needle 2 and an inner needle tube 3 of a piston, two smooth moving components 5 are arranged in mirror image on the outer wall surface of the outer needle tube 1 storing medicine, and the side walls of the two smooth moving components 5 close to each other are connected by multiple groups of connecting and stabilizing components 6, and a protective tube 4 for surrounding protection of the needle 2 is arranged on the smooth moving component 5, and three circumferentially distributed dragging rods 7 are threadedly connected to the bottom of the protective tube 4, and the other end of the dragging rod 7 is connected to the outer wall surface of the hand-gripping end of the inner needle tube 3 of the piston through a bearing, and the dragging rod 7 is made of "L"-shaped rubber material;

[0028] In order to ensure that the protective tube 4 can protect the needle 2 after the injection is completed, the height of the protective tube 4 is twice the sum of the heights of the outer needle tube 1 and the needle 2;

[0029] In order to ensure that the protection tube 4 does not collide with the connection and stabilization component 6 during the up and down movement, the inner wall of the protection tube 4 is one to two centimeters away from the outermost end of the connection and stabilization component 6;

[0030] Specifically, the protective tube 4 can provide a surrounding protective effect for the needle 2 after the injection of the items used to repair the body's nutrition is completed, preventing the needle 2 from scratching and injuring the exposed skin of people around due to urgent pressure, external force collision and other pressures before the injection protective cover is covered and when the needle 2 is pulled out after the injection, effectively preventing people from being infected by drugs or cross-infected by viruses due to the bacteria on the needle 2 after the injection, and effectively enhancing the safety of the treatment during the entire treatment process of injecting drugs; the stable moving component 5 can be used to drag the support rod 7 to drive the protective tube 4 to move up and down smoothly, so as to provide a surrounding protective effect for the needle 2 after the drug is injected, preventing the needle 2 from scratching and injuring people around; the connection and stabilization component 6 can be used to assemble and connect the two stable moving components 5, preventing the protective tube 4 from accidentally falling from the stable moving component 5 during use, and effectively ensuring the protective effect of the needle 2;

[0031] When in use, medical staff can mirror-image the two smooth moving components 5 on the outer wall surface of the outer medicine storage needle tube 1, so that the lowest end of the smooth moving component 5 is flush with the lowest end of the outer medicine storage needle tube 1, and then the protective tube 4 is plugged into the smooth moving component 5, and then the movable ends of the three drag support rods 7 set on the outer wall surface of the piston inner needle tube 3 can be connected to the bottom of the protective tube 4. After the assembly is completed, pulling the piston inner needle tube 3 can suck the medicine into the inner cavity of the outer medicine storage needle tube 1. At this time, the distance between the upper end of the protective tube 4 and the injection end of the needle 2 gradually increases. When the piston inner needle tube 3 is pushed for injection, the upper end of the protective tube 4 gradually approaches the injection end of the needle 2. When the injection is completed, the upper end of the protective tube 4 and the injection end of the needle 2 are on the same horizontal axis, and then the protective tube 4 can play a surrounding protective effect on the needle 2 after the injection of the medicine, to prevent the needle 2 from scratching and injuring people around, and to prevent people from forming drug infection or virus cross-infection due to the bacteria carried on the needle 2 after injection.

[0032] like Figure 2 As shown, the protection tube 4 is made of a transparent and drop-resistant material (such as polycarbonate), and scale lines are provided on the outer wall surface of the protection tube 4;

[0033] Specifically, by providing a transparent protective tube 4 with scale lines, it is convenient to observe the drug capacity inside the drug storage outer needle tube 1 in real time, so that the pillow can monitor the amount of injected drug in real time.

[0034] like Figure 3 As shown, the stable movement component 5 includes a connecting outer column 502, a semi-circular connecting outer column 502 is arranged on the outer wall surface of the medicine storage outer needle tube 1, a plurality of "T"-shaped balancing sliding grooves 503 are opened on the outer wall surface of the connecting outer column 502, and the inner cavity of the balancing sliding groove 503 is slidably connected with a balancing slider 501 bonded to the inner wall surface of the protection tube 4;

[0035] Specifically, by inserting a balancing slider 501 with a protective tube 4 connected to one side into the balancing sliding groove 503, the purpose of sleeve-connecting the protective tube 4 on the outside of the medicine storage outer needle tube 1 can be achieved. When the needle tube 3 inside the piston is pulled, the protective tube 4 can be driven to move up and down smoothly with the cooperation of the dragging support rod 7, ensuring that the protective tube 4 can play a surrounding protective role for the needle 2 after injecting the medicine, preventing the needle 2 from scratching and injuring people around.

[0036] like Figure 3 As shown, a silicone pad is connected to the inner wall surface of the connecting outer column 502;

[0037] Specifically, the silicone pad can increase the contact area between the connecting outer column 502 and the outer wall of the outer medicine storage needle tube 1, thereby increasing the friction between the outer medicine storage needle tube 1 and the connecting outer column 502 and avoiding wear on the outer wall of the outer medicine storage needle tube 1.

[0038] like Figure 4 As shown, the connection and stabilization component 6 includes a first positioning block 601 and a second positioning block 602, and the first positioning block 601 and the second positioning block 602 are respectively bonded to the outer wall surfaces of the two balancing sliders 501 that are close to each other, and the first positioning block 601 and the second positioning block 602 are respectively provided with a second threaded through hole and a first threaded through hole 603, and the second threaded through hole and the first threaded through hole 603 are threadedly connected with the same fastening threaded rod 604;

[0039] Specifically, by mirror-setting the two connecting outer columns 502 on the outer wall surface of the medicine storing outer needle tube 1, the side walls of the first positioning block 601 and the second positioning block 602 on the same horizontal axis are fitted together, and then the fastening threaded rod 604 is threadedly connected between the threaded through hole 1 603 and the threaded through hole 2, the connection and fixing operation of the first positioning block 601 and the second positioning block 602 can be achieved, thereby effectively enhancing the installation firmness between the two connecting outer columns 502, avoiding loosening of the connection between the two stable moving components 5 during use, and ensuring the protective effect of the protective tube 4 on the needle 2.

[0040] In summary, the protective tube 4 can provide a protective surrounding effect on the needle 2 after the injection of the substance used to repair the body's nutrition is completed, preventing the needle 2 from scratching and piercing the exposed skin of people around due to urgent pressure, external force collision, etc. before being covered with the injection protective cover and during the process of pulling out the needle 2 after the injection, effectively preventing people from being infected by drugs or cross-infected by viruses due to the bacteria carried on the needle 2 after the injection, and effectively enhancing the safety of the treatment during the entire treatment process of injecting drugs;

[0041] By inserting the balancing slider 501 with the protection tube 4 connected to one side into the balancing sliding groove 503, the protection tube 4 can be sleeved on the outside of the outer needle tube 1 storing medicine. When the inner needle tube 3 of the piston is pulled, the protection tube 4 can be driven to move up and down smoothly under the cooperation of the dragging support rod 7, so as to play a surrounding protection role for the needle 2 after injecting medicine, so as to prevent the needle 2 from scratching and injuring people around.

[0042] The connection and stabilization component 6 provided can play an assembly and connection role for the two smoothly moving components 5, thereby preventing the protective tube 4 from accidentally falling off the smoothly moving component 5 during use. When in use, the two connecting outer columns 502 are mirror-imaged on the outer wall surface of the medicine storing outer needle tube 1. At this time, the side walls of the first positioning block 601 and the second positioning block 602 on the same horizontal axis are in contact with each other, and then the fastening threaded rod 604 is threadedly connected between the threaded through hole 1 603 and the threaded through hole 2, so as to realize the connection and fixing operation of the first positioning block 601 and the second positioning block 602, thereby effectively enhancing the installation firmness between the two connecting outer columns 502, preventing the two smoothly moving components 5 from loosening at the connection during use, and ensuring the protective effect of the protective tube 4 on the needle 2.
