Description

Technical Field

[0001] This utility model relates to the field of injection device technology, specifically to a tracer quantitative injection device. Background Technology

[0002] A tracer metering device is an important piece of equipment used in scientific research experiments, medical diagnosis, and industrial production processes to precisely control the amount of tracer injected.

[0003] Traditional tracer injection devices are mostly manually operated, using a manual piston or knob to control the injection volume of tracer. However, manually operated tracer injection devices have the drawback of not being able to achieve completely quantitative operation. Since manual operation relies on the operator's subjective judgment and experience, it is difficult to achieve precise quantitative injection, especially in scientific research experiments and medical diagnosis where strict control of injection volume is required. This error may have a significant impact on experimental results or diagnostic accuracy. In addition, manual operation is also easily affected by external environmental factors, such as operator fatigue and unstable operating environment, which further increases the uncertainty of injection volume. Therefore, a tracer quantitative injection device is proposed to solve the above-mentioned problems. Utility Model Content

[0026] Please see Figure 1-3 A tracer quantitative injection device includes a housing 1 and a quantitative adjustment component. The housing 1 is composed of an inner shell 101, an outer shell 102 and a connecting end 103. The quantitative adjustment component is provided between the inner shell 101 and the outer shell 102 and outside the outer shell 102.

[0027] The quantitative adjustment assembly includes two connecting rods 7 and two stop blocks 11. The inner shell 101 is cylindrical, and the outer shell 102 is installed outside the inner shell 101. An adjustment groove 6 is provided between the outer shell 102 and the top and bottom of the inner shell 101. The two connecting rods 7 are located in the two adjustment grooves 6 respectively. Two sets of symmetrically distributed fixing holes 10 are provided at the top and bottom of the outer shell 102. The two stop blocks 11 are installed at the top and bottom of the outer shell 102 near the two sets of fixing holes 10 respectively.

[0028] In this embodiment, the connecting end 103 is installed at one end of the connection between the inner shell 101 and the outer shell 102, and the inner shell 101, the outer shell 102 and the connecting end 103 are integrally formed, and the injection end 2 is inserted into the connecting end 103.

[0029] In this embodiment, a push block 3 is inserted into the inner shell 101, and a push rod 4 is provided on the side of the push block 3 away from the connecting end 103. The push block 3 and the push rod 4 are integrally formed, and a rubber block is provided on the outside of the push block 3.

[0030] It should be noted that the integrated molding design of push block 3 and push rod 4 enhances the overall structure and the efficiency of force transmission, and the rubber block increases the sealing between push block 3 and inner shell 101.

[0031] In this embodiment, the push rod 4 is located away from the push block 3. After passing through the other end of the connection between the inner shell 101 and the outer shell 102, a hand-held block 5 is welded to it. The two connecting rods 7 also pass through the outer shell 102 and are welded to the hand-held block 5.

[0032] It should be noted that the design of the hand-held block 5 allows the operator to easily grasp and push the push rod 4. At the same time, the welding of the two connecting rods 7 to the hand-held block 5 enhances the stability of the structure and prevents the push rod 4 from shaking or deviating during the pushing process.

[0033] In this embodiment, the two connecting rods 7 are respectively welded with guide blocks 8 at the end away from the hand-held block 5 and the side away from the inner shell 101. The top and bottom of the outer shell 102 are respectively provided with guide grooves 9 corresponding to the two guide blocks 8, and are respectively slidably connected to the two guide blocks 8.

[0034] It should be noted that the sliding connection design between guide block 8 and guide groove 9 ensures the stability and straightness of push rod 4 and push block 3 during the pushing process.

[0035] In this embodiment, each stop 11 consists of an arc-shaped connecting plate 1101, two inserts 1102, and a hand ring 1104. The two inserts 1102 are symmetrically distributed and welded to the inner wall of the arc-shaped connecting plate 1101, and their ends are fixedly installed with magnets 1103. The hand ring 1104 is welded to the middle of the outer wall of the arc-shaped connecting plate 1101.

[0036] It should be noted that the design of the stop block 11 allows the operator to easily adjust its position to limit the stroke of the push block 3, thereby determining the injection unit amount. The design of the magnet 1103 and the iron block in the fixing hole 10 magnetically fixed not only enhances the stability of the stop block 11, but also makes the adjustment process more convenient and faster. The design of the hand ring 1104 provides a convenient grip point, making it easy for the operator to make adjustments.

[0037] In this embodiment, an iron block is fixedly installed in each fixing hole 10. The two inserts 1102 on the stop block 11 are respectively inserted into two corresponding holes on a set of fixing holes 10, and the magnets 1103 at their ends are attracted to the iron blocks in the fixing holes 10.

[0038] Beneficial effects:

[0039] The tracer quantitative injection device is integrally formed by push block 3 and push rod 4 and inserted into inner shell 101. By operating hand block 5, the tracer can be smoothly pushed for quantitative injection. Two connecting rods 7 not only pass through outer shell 102 and are welded to hand block 5, but also have guide blocks 8 welded to their other ends, which are slidably connected to guide grooves 9 on outer shell 102. This ensures the stability and straightness of push rod 4 and push block 3 during the pushing process, thereby further improving the accuracy of injection volume. In addition, two stops 11 are magnetically fixed to iron blocks in fixing holes 10 by insert blocks 1102 on them. This not only makes it easy to adjust the position of stops 11 to limit the stroke of push block 3 and thus determine the injection volume, but also ensures the firmness of stops 11 and the convenience of operation.
