Description

Technical Field

[0001] This utility model relates to the field of infusion device technology, specifically to a wear-resistant infusion device. Background Technology

[0002] For disease types requiring long-term management of drug levels in the body, daily injection therapy is necessary, with insulin or other essential medications being common treatments. With continuous technological advancements, needle-free injectors, as a more convenient and pain-reducing injection method, are increasingly attracting widespread attention from patients and the medical community.

[0003] However, traditional needle-free injectors used for long-term drug injection do have some shortcomings during use, one of which is that their internal precision components are easily damaged by impacts. Specifically, the drawbacks of traditional needle-free injectors for long-term injection include: 1. The internal structure of needle-free injectors is highly precise, containing many key components such as springs, pistons, and nozzles. These delicate parts are easily damaged or deformed when subjected to external impacts, thus affecting the accuracy and overall lifespan of the injector; 2. Impact sensitivity: Since needle-free injectors rely on high pressure to inject drugs through tiny orifices into the skin, their internal mechanical structure is extremely sensitive to impacts. Even a slight collision can cause misalignment or damage to components, thereby affecting the injection effect.

[0004] In light of this, in-depth research into the aforementioned issues led to the creation of this case. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model is implemented through the following technical solution:

[0006] A wear-resistant infusion set includes: an infusion tube, a protective sleeve, and a protective infusion structure. The infusion tube is installed inside the protective sleeve via the protective infusion structure. The protective infusion structure includes: two pairs of rotating sliders, a pressing air bladder, an expansion air bladder, a circular ring limiting sleeve, a pneumatic drainage tube, a limiting circular ring block, a pressing dumbbell-shaped cylindrical block, a pair of check valves, and protective components.

[0007] The inner side of the protective sleeve is provided with two pairs of L-shaped rotating limiting grooves. Two pairs of rotating sliders are installed on the outer side of the infusion tube, and the two pairs of rotating sliders are respectively movably inserted into the inner side of the two pairs of L-shaped rotating limiting grooves. The expansion airbag is installed on the inner side of the annular limiting sleeve. The annular limiting sleeve is installed on the infusion tube. The limiting annular block is installed on the inner side of the protective sleeve. The pressing airbag is installed on the limiting annular block. The pressing dumbbell-shaped cylindrical block is movably inserted into the protective sleeve and connected to the pressing airbag. A pair of check valves are installed on the pressing airbag. The air pressure drainage tube is connected to the expansion airbag and the check valves on the pressing airbag. The protective assembly is installed on the inner side of the protective sleeve.

[0008] Preferably, the protective assembly includes: a rotating adjusting rod, a rotating extrusion ring, two pairs of arc extrusion blocks, and two pairs of arc extrusion rubber rings;

[0009] The protective tube of the set has a spider web annular groove. Two pairs of arc extrusion rubber rings are evenly installed on the inner side of the spider web annular groove. The rotating extrusion ring is inserted into the inner side of the spider web annular groove by a support. Two pairs of arc extrusion blocks are installed on the rotating extrusion ring.

[0010] Preferably, the protective tube of the kit is provided with a number of auxiliary balls.

[0011] Preferably, the protective tube of the kit is provided with an observation plastic block.

[0012] Preferably, the protective tube of the kit is provided with graduations.

[0013] Preferably, the ratio of the inner diameter of the compression airbag to that of the expansion airbag is 5:1.

[0014] Beneficial effects

[0015] This invention provides a wear-resistant infusion set, which has the following beneficial effects:

[0016] First, it boasts excellent wear resistance. Through the precise fit between the protective components and the protective sleeve, the infusion tubing maintains high stability and wear resistance even during frequent movements and adjustments. In particular, the observation plastic block on the outside of the protective sleeve not only enhances the wear resistance of the entire device but also effectively prevents damage caused by external impacts.

[0017] Secondly, the protection has been comprehensively upgraded. The ingenious combination of two pairs of rotating sliders and L-shaped rotating limiting grooves ensures the precise positioning of the infusion tube during rotation and extension; at the same time, the arc-shaped compression rubber ring in the protective component provides flexible secondary cushioning, further protecting the infusion tube from accidental impacts.

[0018] Furthermore, it is simple and flexible to operate. Pressing the dumbbell-shaped cylindrical block easily controls the inflation and deflation of the compression and expansion airbags, enabling precise adjustment of the infusion tube position; while the combination of rotating the squeezing ring and the arc squeezing block makes limiting and unlocking the infusion tube simple and quick.

[0019] Furthermore, the design details demonstrate a human-centered approach. The auxiliary ball on the protective tube reduces friction, while the scale facilitates monitoring of the dosage. In particular, the design of the ratio of the inner diameter of the pressing airbag and the inflating airbag not only allows for adjustment of the high-pressure effect but also makes the expansion and contraction effect more precise and controllable.

[0024] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Example

[0026] like Figure 1-3 As shown, the infusion tube 1 is installed inside the protective tube 2 via the protective infusion structure. The protective infusion structure includes: two pairs of rotating sliders 3, a pressing airbag 4, an expanding airbag 5, a circular ring limiting sleeve 6, a pneumatic drainage tube 7, a limiting circular ring block 8, a pressing dumbbell-shaped cylindrical block 9, a pair of check valves 12, and protective components.

[0027] Specifically, the inner side of the protective sleeve 2 is provided with two pairs of L-shaped rotating limiting grooves 13, the two pairs of rotating sliders 3 are installed on the outer side of the infusion tube 1, and the two pairs of rotating sliders 3 are respectively movably inserted into the inner side of the two pairs of L-shaped rotating limiting grooves 13. The expansion airbag 5 is installed on the inner side of the annular limiting sleeve 6, the annular limiting sleeve 6 is installed on the infusion tube 1, the limiting annular block 8 is installed on the inner side of the protective sleeve 2, the pressing airbag 4 is installed on the limiting annular block 8, the pressing dumbbell-shaped cylindrical block 9 is movably inserted into the protective sleeve 2, and the pressing dumbbell-shaped cylindrical block 9 is connected to the pressing airbag 4. A pair of check valves 12 are installed on the pressing airbag 4. The air pressure drainage tube 7 is connected to the expansion airbag 5 and the check valves 12 on the pressing airbag 4. The protective component is installed on the inner side of the protective sleeve 2.

[0028] It should be noted that, as described above, the infusion tube 1 on the protective component drives the two pairs of rotating sliders 3 on it. These sliders 3 then rotate and extend stably along the two pairs of L-shaped rotating limiting grooves 13 inside the protective tube 2, thus horizontally extending and retracting the infusion tube 1 inside the protective tube 2. Pressing the dumbbell-shaped cylindrical block 9 compresses the tube, which in turn drives the pressing airbag 4. The gas inside the pressing airbag 4 is then drained through the check valve 12 to the inside of the air pressure drainage pipe 7, and finally, through the air pressure drainage pipe 7, the gas is drained to the inflatable airbag 5. Inside, when the dumbbell-shaped cylindrical block 9 is pressed to rise and fall, the check valve 12 between the airbag 4 and the expansion airbag 5 becomes sealed due to the one-way drainage effect. Similarly, pressing the dumbbell-shaped cylindrical block 9 to rise and fall draws the air outside the other check valve 12 to the inside of the airbag 4, thereby driving the gas inside the airbag 4 to flow to the inside of the expansion airbag 5 one by one. Because the inner diameters of the airbag 4 and the expansion airbag 5 are different, the pressing and stretching effect is reduced. The infusion tube 1 is protected by the protective tube 2 to prevent shaking caused by bumps. The protective component provides secondary auxiliary buffering for the infusion tube 1.

[0029] like Figure 1-3 As shown, the protective assembly includes: a rotating extrusion ring 10, two pairs of arc extrusion blocks 11, and two pairs of arc extrusion rubber rings 15;

[0030] Specifically, the protective sleeve 2 has a spider web annular groove 14, two pairs of arc extrusion rubber rings 15 are evenly installed on the inner side of the spider web annular groove 14, the rotating extrusion ring 10 is inserted into the inner side of the spider web annular groove 14 by a support, and two pairs of arc extrusion blocks 11 are installed on the rotating extrusion ring 10.

[0031] As a preferred option, the protective tube 2 of the set is further provided with several auxiliary balls.

[0032] As a preferred option, the protective tube 2 of the set is further provided with an observation plastic block.

[0033] As a preferred option, the protective tube 2 is further provided with a scale 16.

[0034] As a preferred embodiment, the inner diameter ratio of the compression airbag 4 to the inflatable airbag 5 is 5:1.

[0035] It should be noted that, as described above, by rotating the extrusion ring 10, the circular extrusion block 11 on it is driven by the rotating extrusion ring 10. The rotating circular extrusion block 11 extrudes the circular extrusion ring 15, pressing the circular extrusion ring 15 onto the infusion tube 1, thereby limiting the infusion tube 1 to the inside of the protective tube 2. The flexible circular extrusion ring 15 provides cushioning. When the rotating extrusion ring 10 on the protective tube 2 is rotated in the opposite direction, the infusion tube 1 is released. The auxiliary balls on the protective tube 2 provide stable lifting, lowering, and rotation. Several auxiliary balls are combined to form a simple linear bearing, avoiding friction. At the same time, the observation plastic block fitted on the outside of the protective tube 2 provides comprehensive wear-resistant treatment for the entire device. The protective tube 2 is cleverly placed on the outside of the pressing device. Its design aims to provide an effective buffer and protective layer for the inner device, thereby significantly improving the wear resistance of the inner device and ensuring the safety and long-term use of the device. At the same time, the main functional components of the entire device are located inside the protective tube 2, avoiding wear and impact. The dosage is monitored by the scale 16 on the protective tube 2. Meanwhile, the pressure effect is adjusted by the different inner diameters of the pressing airbag 4 and the inflating airbag 5, and the expansion effect is proportional.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
