Description

Technical Field

[0001] This utility model relates to the field of blood collection needle packaging technology, specifically a needle handle reversing mechanism for blood collection needle packaging. Background Technology

[0002] Blood collection needles are medical devices used to collect blood samples during medical testing. They are prohibited from being reused. Therefore, medical personnel should avoid contact between their fingers and the needle tip when unpacking to prevent injury and contamination. It is necessary to ensure that the needle handle of the blood collection needle inside the packaging faces outwards from the coiled portion for easy handling. Current packaging methods for blood collection needles include: 1) manual winding, which is inefficient and prone to errors, leading to needle pricks and contamination; and 2) machine packaging, which, for efficiency, simply winds the needle and packages it without specifying the needle handle orientation. This requires extra care from medical personnel when unpacking to prevent needle pricks and wastes resources. Therefore, a needle handle reversing mechanism is needed for blood collection needle packaging. Utility Model Content

[0003] To address the problems existing in the prior art, the purpose of this utility model is to provide a needle handle reversing mechanism for blood collection needle packaging. This mechanism not only ensures that the needle handle faces outward after packaging, protecting the safety of medical personnel and saving resources, but also enables automated mass production, thereby improving production efficiency.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a needle handle reversing mechanism for blood collection needle packaging, comprising a frame and a blood collection needle, the blood collection needle comprising a needle handle and a connecting tube, a conversion component installed at the end of the frame, a guide rail fixedly connected to the side of the frame near the conversion component, a pulling component slidably connected to the guide rail, the conversion component comprising a fixed frame, a first cylinder installed on the fixed frame, a movable plate installed on the telescopic part of the first cylinder, the movable plate being slidably connected to the fixed frame, a movable rod fixedly connected to the movable plate, a second cylinder installed at the end of the fixed frame, a movable frame installed on the telescopic part of the second cylinder, a fixed block installed on the movable frame, a conversion block fixedly connected to the fixed block, the side of the conversion block away from the movable rod being a helical curved surface, the pulling component comprising an electric push rod, a support frame installed on the telescopic part of the electric push rod, a transverse cylinder installed on the support frame, and a clamp installed on the transverse cylinder.

[0005] In some embodiments, a support plate is fixedly connected to one end of the frame near the conversion assembly.

[0006] In some embodiments, a support plate is mounted on the side of the transverse cylinder.

[0007] In some embodiments, ten of each of the moving rod, the fixing block, the conversion block, the transverse cylinder, and the clamp are provided. In some embodiments, the clip is divided into two parts, and the middle part is a hollow circle when the two parts are joined together.

[0008] In some embodiments, the blood collection needle includes a needle handle and a connecting tube, the diameter of which is larger than the diameter of the hollow circle in the middle when the clamps are closed.

[0009] In summary, this utility model has the following beneficial effects: This utility model is equipped with a pulling component and a conversion component. Through the cooperation of the conversion block in the conversion component and the pulling component, after the blood collection needle is fixed, the pulling component is used to pull it so that the needle handle of the blood collection needle is guided by the conversion block to unify the orientation of the needle handle. This makes it convenient to ensure that the needle handle of the blood collection needle faces the outside of the winding part after subsequent winding and packaging, ensuring that medical staff will not be pricked by the needle when unpacking, and avoiding contamination and waste of the blood collection needle.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] See Figures 1-5 A needle handle reversing mechanism for blood collection needle packaging includes a frame 1 and a blood collection needle 5. The blood collection needle 5 includes a needle handle 51 and a connecting tube 52. A conversion component 3 is installed at the end of the frame 1. A guide rail 11 is fixedly connected to the side of the frame 1 near the conversion component 3. A pulling component 4 is slidably connected to the guide rail 11. The conversion component 3 includes a fixed frame 31. A first cylinder 33 is installed on the fixed frame 31. A movable plate 32 is installed on the telescopic part of the first cylinder 33. The movable plate 32 is slidably connected to the fixed frame 31. A movable rod 34 is fixedly connected to the movable plate 32. A second cylinder 35 is installed at the end of the first cylinder 34. A movable frame 36 is installed on the telescopic part of the second cylinder 35. A fixed block 37 is installed on the movable frame 36. A conversion block 38 is fixedly connected to the fixed block 37. The side of the conversion block 38 away from the moving rod 34 is a spiral curved surface 381. The pulling assembly 4 includes an electric push rod 41. A support frame 42 is installed on the telescopic part of the electric push rod 41. A transverse cylinder 43 is installed on the support frame 42. A clamp 44 is installed on the transverse cylinder 43. Ten moving rods 34, fixed blocks 37, conversion blocks 38, transverse cylinders 43 and clamps 44 are provided. In use, the operator places ten lancets 5 into the device using a robotic arm. Initially, the pulling component 4 is positioned close to the conversion component 3, and the telescopic part of the first cylinder 33 is extended, while the telescopic part of the second cylinder 35 is retracted. This keeps the conversion block 38 far from the moving rod 34, facilitating the quick insertion of the lancets 5. At this time, the telescopic part of the electric push rod 41 is extended. Then, when the robotic arm places the ten lancets 5 onto the conversion component 3 and the pulling component 4, the needle handle 51 is located in front of the conversion block 38, while the connecting tube 52 is located behind the clamp 44. Then, the existing intelligent program controls the retraction of the telescopic part of the first cylinder 33, which moves the moving plate 32, and the extension of the telescopic part of the second cylinder 35, which moves the moving frame 36. This causes the conversion block 38 and the moving rod 34 to move towards each other and move closer together, jointly restraining the lancets 5. At the same time, the transverse cylinder 4... 3 also controls the clamp 44 to restrain the blood collection needle 5, and then controls the extension and retraction of the electric push rod 41 to drive the support frame 42 to move away from the conversion component 3 on the frame 1, so that the clamp 44 moves the blood collection needle 5. During the movement of the blood collection needle 5, the needle handle 51 rotates along the spiral surface 381 of the conversion block 38, so that the needle handle 51 rotates to face the direction of the moving rod 34, and the needle handle 51 is uniformly oriented, thus completing the reversal of the needle handle 51 of the blood collection needle 5. Finally, it is wound and bagged, so that the needle handle 51 of the blood collection needle 5 in the packaging bag faces the outside of the winding part. In this way, when medical staff unpack and use it, they do not need to carefully avoid the needle tip to prevent being pricked by the needle tip, thus saving blood collection needle 5 resources. The guiding direction of the spiral surface 381 of the conversion block 38 can be screened according to the direction of the winding machine to ensure that when the blood collection needle 5 is bagged, the needle handle 51 always faces the outside of the winding part.

[0014] In some embodiments, a support plate 2 is fixedly connected to one end of the frame 1 near the conversion component 3. The support plate 45 can support the needle handle 51 of the blood collection needle 5 when the robot arm places the blood collection needle 5 onto the conversion component 3, so as to prevent the needle handle 51 of the blood collection needle 5 from drooping due to gravity, and prevent the needle handle 51 from being stuck and unable to move when the pulling component 4 pulls the blood collection needle 5, thus preventing it from being pulled off, and ensuring that the needle handle 51 of the blood collection needle 5 can be reversed smoothly.

[0015] In some embodiments, a support plate 45 is mounted on the side of the transverse cylinder 43. The support plate 45 can support the connecting tube 52 of the blood collection needle 5 when the robot arm places the blood collection needle 5 onto the clamp 44, so as to prevent the connecting tube 52 of the blood collection needle 5 from drooping too much and being jammed by other parts, which would cause the connecting tube 52 to be jammed and unable to move when the clamp 44 moves the blood collection needle 5, thereby pulling the blood collection needle 5 off.

[0016] In some embodiments, the clamp 44 is divided into two parts, and the middle part is a hollow circle when the two parts are joined together. Before the clamp 44 clamps the blood collection needle 5, the transverse cylinder 43 controls the two parts of the clamp 44 to be spaced apart. After the robot arm places the blood collection needle 5 onto the clamp 44, the transverse cylinder 43 controls the two parts of the clamp 44 to be joined together, clamping the blood collection needle 5 through the hollow circle in the middle.

[0017] In some embodiments, the diameter of the connecting tube 52 is larger than the diameter of the hollow circle in the middle when the clamp 44 is closed. This ensures that when the clamp 44 clamps the connecting tube 52 and pulls the blood collection needle 5, even if the connecting tube 52 can slide within the hollow circle in the middle of the clamp 44, the clamp 44 can still pull the connecting tube 52 to move, ensuring that the direction of the needle handle 51 of the blood collection needle 5 is successfully changed.

[0018] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
