[0029] Please refer to Figure 1 , Figure 1 which is a schematic three-dimensional structure diagram of an infusion set injection part with an anti-pollution component provided by an embodiment of the present application.

[0030] An embodiment of the present application provides an infusion set injection part 100 with an anti-pollution component. The infusion set injection part 100 with an anti-pollution component includes a base tube 110, a liquid inlet tube 120, a liquid adding tube 130, and a dust-proof cap. The base tube 110, the liquid inlet tube 120, the liquid adding tube 130, and the dust-proof cap are integrally connected structures.

[0031] Among them, the base tube 110, the liquid inlet tube 120, and the liquid adding tube 130 are integrally formed by using a rigid plastic with a certain transparency.

[0032] The liquid inlet tube 120 is obliquely connected to and communicates with the base tube 110. The angle of inclination between the liquid inlet tube 120 and the base tube 110 can be about 45 degrees. The specific angle does not limit the present invention.

[0033] The liquid adding tube 130 is arranged at the top of the base tube 110. A valve core 131 is provided inside the top of the liquid adding tube 130. The valve core 131 can be made of flexible silicone material and is limited and inserted into the liquid adding tube 130. The valve core 131 is used to temporarily block the top of the liquid adding tube 130 and can be penetrated by the needle of a syringe when needed for liquid medicine addition. In previous operations, before liquid medicine addition, it was necessary to disinfect the surface of the valve core 131 first and then perform the liquid medicine addition operation.

[0034] Therefore, an embodiment of the present application adds a dust-proof cap to solve this problem. The dust-proof cap provided by the embodiment of the present application is integrally connected to the base tube 110. The dust-proof cap is opened relative to the liquid adding tube 130 when temporarily adding liquid medicine is needed, and the dust-proof cap is hermetically closed relative to the liquid adding tube 130 when temporarily adding liquid medicine is not needed to protect the valve core 131. By adding the dust-proof cap, the liquid adding tube 130 can be better protected from being polluted, and at the same time, cumbersome disinfection operations do not need to be carried out during liquid addition.

[0035] Specifically, in the application embodiment, the dust cover includes a cylindrical body portion 141 and a cover plate portion 142. The cylindrical body portion 141 is used to be matched and connected with the liquid adding tube 130, and the cover plate portion 142 is connected to one end of the cylindrical body portion 141. Of course, in some embodiments, the dust cover can also be a split structure with the base tube 110. It can be understood that when the dust cover adopts a split structure, it is relatively easy to be lost. The dust cover preferably adopts a structure integrally connected with the base tube 110.

[0036] An assembly step matching the cylindrical body portion 141 may be provided at the top of the liquid adding tube 130, and the cylindrical body portion 141 is sleeved on the outer peripheral side of the assembly step.

[0037] The cylindrical body portion 141 may be made of hard plastic, and the cover plate portion 142 is made of soft plastic and integrally formed by a secondary injection molding method.

[0038] In the application embodiment, the infusion device injection part 100 with an anti-pollution component further includes a first rib plate 151. The first rib plate 151 extends in the radial direction of the liquid adding tube 130 and is integrally connected with the cover plate portion 142. The first rib plate 151 can make it easier for medical staff to grasp when adding liquid.

[0039] Between the cover plate portion 142 and the first rib plate 151, there are included a first connecting portion 161 and a second connecting portion 162. The first connecting portion 161 and the second connecting portion 162 have good anti-bending properties. Preferably, the first connecting portion 161 and the second connecting portion 162 are respectively provided with a first groove 163 and a second groove 164 to further facilitate the bending of the first connecting portion 161 and the second connecting portion 162.

[0040] Between the cover plate portion 142 and the first rib plate 151, there is also included a third connecting portion 165. The third connecting portion 165 is arranged between the first connecting portion 161 and the second connecting portion 162 and protrudes in a V shape from the connection surface formed by the cover plate portion 142 and the first rib plate 151.

[0041] The infusion device injection part 100 with an anti-pollution component further includes a second rib plate 152. The second rib plate 152 extends in the axial direction of the liquid inlet tube 120 and is integrally connected with the first rib plate 151, further improving the overall mechanical strength of the infusion device injection part 100 with an anti-pollution component and facilitating the grasping by medical staff when adding liquid. Both the first rib plate 151 and the second rib plate 152 are made of hard plastic.

[0042] Please refer to Figure 2 , Figure 2 which is a schematic side structure diagram of the infusion device provided by the application embodiment.

[0043] As Figure 2As shown in the figure, an embodiment of the present application further provides an infusion device, which includes the aforementioned infusion syringe 100 with an anti-pollution component. The infusion device further includes a bottle stopper puncture device 200, a drip chamber 300, a flow rate regulator 400, a connector 500, and an infusion needle 600 connected by an infusion hose. The bottle stopper puncture device 200 is further connected with an air inlet tube 210, and an air filter can generally be arranged at the free end of the air inlet tube 210. An infusion switch clamp 220 is further arranged between the bottle stopper puncture device 200 and the drip chamber 300. The bottle stopper puncture device 200, the drip chamber 300, the flow rate regulator 400, the connector 500, and the infusion needle 600 are existing conventional components and will not be elaborated in this application.

[0044] In summary, those skilled in the art can easily understand that the infusion syringe 100 with an anti-pollution component provided by the present application is provided with a dust-proof cover. The dust-proof cover can be opened relative to the liquid adding tube 130 when it is necessary to temporarily add liquid medicine, and the dust-proof cover can be hermetically closed relative to the liquid adding tube 130 to protect the valve core 131 when it is not necessary to temporarily add liquid medicine. Therefore, the liquid adding operation of medical staff can be simplified and the infection risk of patients can be greatly reduced.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
