Description

Technical Field

[0001] The utility model relates to the technical field of injection, in particular to an injection positioning device. Background Art

[0002] An injection, which involves injecting liquids or gases into the body with the aid of a medical device such as a syringe, is different from taking medication. While medications can quickly reach the bloodstream and take effect, inexperienced trainee nurses are prone to manual manipulation during injections, which can lead to needle misalignment. Furthermore, prolonged contact between the positioning device and the syringe can wear away the markings on the syringe's outer wall, making it difficult for medical staff to accurately administer the injection.

[0003] After searching, the Chinese patent authorization number CN 214435665 U discloses an injection positioning device for endocrinology, including a positioning device, a sliding rod passing through the positioning device, a fixed block fixed to one side of the sliding rod by glue, a screw screwed on the fixed block, a pressing block provided below the sliding rod, a support rod provided inside the positioning device, a support block installed above the support rod, a slot provided on both the support block and the pressing block, a rubber pad connected to the inside of the slot. The above patent has the following shortcomings: when positioning and fixing the syringe, the sliding rod is fixed by rotating the fixed block, and the process is slow, making it impossible to quickly position the syringe, and when the injection is completed, the syringe cannot be quickly released from the position, making it impossible for medical staff to complete the fixing of the syringe in one step. Utility Model Content

[0004] The utility model aims to solve the problem in the prior art that a syringe cannot be quickly positioned and released, and proposes an injection positioning device.

The arc limiting plate 9 compresses the first spring 16 through the guide rod 10 to slide into the cavity of the mounting plate 8, and then the trapezoidal block 7 slides over the arc limiting plate 9. Under the action of the first spring 16, the arc limiting plate 9 is reset and clamped with the trapezoidal block 7 to limit the trapezoidal block 7, thereby limiting the trapezoidal block 7, so that the sliding rod 4 is fixed, thereby positioning the syringe.

[0027] The sliding rod 4 passes through the positioning shell body 1 and is slidably connected to the positioning shell body 1. A second spring 13 is sleeved on the surface of the sliding rod 4. One end of the second spring 13 is fixedly connected to the connecting plate 5, and the other end of the second spring 13 is fixedly connected to the mounting plate 8. When the sliding rod 4 slides downward to drive the first positioning plate 2 to position the syringe, the second spring 13 will be compressed. When the syringe is disassembled, the second spring 13 helps to automatically reset the sliding rod 4.

[0028] A limiting groove 14 that is compatible with the trapezoidal block 7 is provided on the surface of the mounting plate 8. A cavity is provided in the mounting plate 8 near the limiting groove 14. The arc-shaped limiting plate 9 is slidably connected in the cavity of the mounting plate 8. The arc-shaped limiting plate 9 can be guided and supported by the guide rod 10 during the sliding process, which helps to make the arc-shaped limiting plate 9 slide horizontally.

[0029] A rotation groove is provided on the surface of the arc-shaped limit plate 9 near the inner side of the cavity of the mounting plate 8, and the guide rod 10 is rotatably connected in the rotation groove of the arc-shaped limit plate 9. The guide rod 10 passes through the cavity of the mounting plate 8 and is slidably connected to the cavity of the mounting plate 8.

[0030] The cross-slot plate 12 has vertical and horizontal grooves that match the clamping plate 11. The vertical grooves of the cross-slot plate 12 are deeper than the horizontal grooves. A rectangular handle 15 is fixedly connected to the right end surface of the guide rod 10. The rectangular handle 15 is slidably connected to the vertical grooves of the cross-slot plate 12. The guide rod 10 passes through the cross-slot plate 12 and is slidably connected to the cross-slot plate 12.

[0031] The first spring 16 rotates through the circular groove of the mounting plate 8, so that the card plate 11 rotates to align with the vertical groove of the cross groove plate 12, and then drives the rectangular handle 15 and the card plate 11 into the vertical groove of the cross groove plate 12 under the action of the first spring 16, which can prevent the medical staff from accidentally touching the rectangular handle 15 and pulling, thereby making the syringe positioned more stable.

[0032] The first positioning plate 2 is fixedly connected to the bottom of the sliding rod 4, a support column 17 is fixedly connected to the bottom inner wall of the positioning shell body 1, the second positioning plate 3 is fixedly connected to the top of the support column 17, the surfaces of the first positioning plate 2 and the second positioning plate 3 are fixedly connected with an anti-slip sponge cover 18, and the back surface of the positioning shell body 1 is fixedly connected with four support rods 19. The four support rods 19 are fixedly connected to the end away from the positioning shell body 1 with a soft cotton pad 20. The anti-slip sponge cover 18 can protect the surface of the syringe from wear.

[0033] There are two groups of trapezoidal blocks 7 and arc-shaped limiting plates 9, and both are symmetrically arranged with the center line of the positioning housing body 1 as the symmetry axis.

[0034] When the syringe needs to be fixed, the syringe is placed on the second positioning plate 3, and the sliding rod 4 is pressed downward to drive the connecting plate 5 and the connecting rod 6 downward, thereby driving the trapezoidal block 7 downward into the limiting groove 14 of the mounting plate 8, and then the trapezoidal block 7 contacts the arc surface of the arc limiting plate 9, so that the arc limiting plate 9 drives the guide rod 10 to compress the first spring 16 and slide, and then the trapezoidal block 7 slides over, and the first spring 16 resets the arc limiting plate 9 and blocks it to limit the position, thereby positioning the syringe, and then the rectangular handle 15 is slightly pulled outward and rotated, so that the guide rod 10 drives the card plate 11 to disengage from the horizontal groove of the cross groove plate 12 and enter the vertical groove, so that the rectangular handle 15 and the card plate 11 both enter the vertical groove of the cross groove plate 12, which helps to prevent accidental contact and prevents the syringe from loosening during use.

[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
