Description

Technical Field

[0001] This invention relates to medical devices, specifically a powder-liquid integrated piston. Background Technology

[0002] When administering medication to patients, the fastest and most effective method is direct intravenous infusion. Before traditional infusion, doctors or nurses need to use a syringe to inject some of the medication solution into various powder vials for mixing, and then use the syringe to inject the mixed liquid back into the original IV bag. The entire process is relatively laborious.

[0003] Although some manufacturers mix the powder and liquid medicines during production, some patients are often allergic to certain medications during treatment, making this method extremely impractical. Summary of the Invention

[0004] In order to overcome the above-mentioned defects in the mixing of powder and liquid medicine, the present invention proposes a powder-liquid integrated piston.

[0005] The technical problem to be solved by this invention is achieved by the following technical solution:

[0006] A medical infusion bottle includes a main body with a hook at the top and an infusion port, a sealing ring, and several powder inlets at the bottom. Each powder inlet is sealed with a sealing paper. The main body primarily holds liquid medication. The infusion port is used to connect to an infusion tubing. The sealing paper seals the corresponding powder inlets, and each powder inlet can be used to connect to different medications.

[0007] As a further improvement of the present invention, a sealing cap is installed at the infusion interface, and a plastic plug is provided in the middle of the sealing cap. That is, before actual infusion, it is only necessary to insert the upper part of the infusion tubing into the plastic plug.

[0008] As another improvement of the present invention, a powder-liquid integrated piston is provided, comprising an outer ring plug integrally formed with a sealing convex ring, and an inner ring plug that can slide vertically within the inner cavity of the outer ring plug. The inner ring plug has several threaded holes, and a connecting component is provided above each threaded hole. A threaded rod is threadedly fitted into each threaded hole. The sealing convex ring and the outer ring plug are tightly joined vertically and are of the same diameter and concentric, thus forming a common, relatively sealed inner cavity. The connecting component connects the interior of the main bottle with the inner cavities of the sealing convex ring and the outer ring plug to facilitate drug mixing. Each threaded rod can be raised or lowered by screwing.

[0009] As a further improvement of the present invention, a limiting ring is provided on the inner side of the outer ring plug; a lower step is provided on the upper part of the inner ring plug; a spring is provided connecting the limiting ring and the lower step. The lower step abuts against the inner side of the outer ring plug, and the limiting ring abuts against the outer side wall of the inner ring plug. This structure allows the inner ring plug to automatically and elastically return to its original position after use, while maintaining a tight seal, thus ensuring the stability of the inner cavity.

[0010] As a further improvement of the present invention, each threaded hole is located directly below the corresponding powder interface. The number and distribution of the threaded holes are set according to the number and distribution of the powder interfaces.

[0011] As a further improvement of the present invention, each threaded rod has a vial fixedly connected to its upper end, and each threaded rod has a threaded head at its lower part. Each vial is used to hold different types of medicinal powder. The threaded head is provided for ease of manual operation.

[0012] As a further improvement of the present invention, the connecting component comprises a fixed collar that is vertically slidably installed within the sealed cavity formed by the sealing convex ring and the inner ring plug, and several metal tubes installed on the fixed collar, each metal tube having pointed conical ends. The upper and lower ends of the metal tubes can puncture the mouth of the vial and the sealing paper. The number and distribution of the metal tubes are also correspondingly set according to the number and distribution of the powder interface.

[0013] As a further improvement of the present invention, the upper part of the outer ring plug is provided with a lateral sliding groove, and a top cover is slidably installed at the lateral sliding groove. The mixing operation can only be carried out after the top cover is slid open.

[0014] As a further improvement of the present invention, the upper end of the inner ring plug is provided with an upper step that abuts against the limiting ring. The upper step serves as a limiting element.

[0015] The beneficial effects of this invention are:

[0016] This invention facilitates the mixing of powdered and liquid medicines, and provides excellent sealing during mixing to prevent leakage. Furthermore, it allows for selective mixing of powdered medicines, thus possessing significant practical applications in the medical field. Attached Figure Description

[0023] To enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be described more clearly and completely below with reference to the accompanying drawings in the embodiments. Of course, the described embodiments are only a part of the present invention and not all of it. Based on this embodiment, other embodiments obtained by those skilled in the art without creative effort are all within the protection scope of the present invention.

[0024] like Figures 1 to 4 As shown, a medical infusion bottle includes a main body 1. The upper end of the main body 1 has a hook 2, and the lower end of the main body 1 has an infusion port 1a, a sealing ring 1b, and several powder inlets 1c. Each powder inlet 1c is sealed with a sealing paper 3. The main body 1 primarily stores liquid medication. The infusion port 1a is used to connect to an infusion tubing. The sealing paper 3 is used to seal the corresponding powder inlet 1c. Each powder inlet 1c can be used to connect to different medications.

[0025] like Figure 1 As shown, a sealing cap 4 is installed at the infusion port 1a, and a plastic plug 4a is provided in the middle of the sealing cap 4. That is, before the actual infusion, simply insert the upper end of the infusion tubing into the plastic plug 4a.

[0026] like Figures 1 to 4 As shown, a powder-liquid integrated piston includes an outer ring plug 5 integrally formed with a sealing convex ring 1b. The inner cavity of the outer ring plug 5 has an inner ring plug 6 that can slide vertically. The inner ring plug 6 has several threaded holes 6b, and a connecting component is provided above each threaded hole 6b. Each threaded hole 6b has a threaded rod 8 threadedly engaged. The sealing convex ring 1b and the outer ring plug 5 are tightly joined vertically and are of the same diameter and concentricity, thus forming a common, relatively sealed inner cavity. The connecting component connects the interior of the main bottle 1 with the inner cavities of the sealing convex ring 1b and the outer ring plug 5 to facilitate drug mixing. Each threaded rod 8 can be raised or lowered by screwing.

[0027] like Figure 3 and Figure 4 As shown, the outer ring plug 5 has a limiting ring 5a on its inner side; the inner ring plug 6 has a lower step 6a on its upper part; a spring 7 connects the limiting ring 5a and the lower step 6a. The lower step 6a abuts against the inner side of the outer ring plug 5, and the limiting ring 5a abuts against the outer wall of the inner ring plug 6. This structure allows the inner ring plug 6 to automatically and elastically return to its original position after use, ensuring the stability of the inner cavity, while maintaining a tight seal.

[0028] like Figure 4 As shown, each threaded hole diameter 6b is located directly below the corresponding powder interface 1c. The number and distribution of threaded holes 6b are set according to the number and distribution of powder interfaces 1c.

[0029] like Figure 4 As shown, each threaded rod 8 has a vial 10 fixedly connected to its upper end, and each threaded rod 8 has a threaded head 8a at its lower part. Each vial 10 is used to hold different types of medicinal powder. The threaded head 8a is provided for ease of manual operation.

[0030] like Figure 4 As shown, the connecting component consists of a fixed collar 12, which is vertically slidably installed within the sealed cavity formed by the sealing protrusion 1b and the inner ring plug 6, and several metal tubes 9 installed on the fixed collar 12. Each metal tube 9 has pointed conical ends. The upper and lower ends of the metal tubes 9 can puncture the mouth of the vial and the sealing paper 3. The number and distribution of the metal tubes 9 are also set according to the number and distribution of the powder interface 1c.

[0031] like Figure 4 As shown, the upper part of the outer ring plug 5 is provided with a lateral sliding groove 5b, and a top cover 11 is slidably installed at the lateral sliding groove 5b. The mixing operation can only be carried out after the top cover 11 is slid open.

[0032] like Figure 4 As shown, the upper end of the inner ring plug 6 is provided with an upper step 6c that abuts against the limiting ring 5a. The upper step 6c serves as a limiting element.

[0033] The specific drug mixing operation of this invention is as follows:

[0034] First, pull open the top cover 11.

[0035] Furthermore, depending on the type of powder to be mixed, the threaded rod 8 corresponding to these powders is screwed upwards, causing the corresponding vials 10 to slide upwards. This causes the vials 10 to first squeeze the fixing ring 12 and the metal tube 9, that is, to allow the metal tube 9 to move upwards until it punctures the sealing paper 3, allowing the liquid in the main bottle 1 to enter the inner cavity.

[0036] Furthermore, the inner ring stopper 6 is manually pushed upwards, causing the lower end of the metal tube 9 to puncture the mouth of the vial 10 corresponding to the screwed threaded rod 8. The vial 10 corresponding to the unscrewed threaded rod 8 will only be displaced and cannot be punctured, thus allowing only specific powders to participate in the mixing.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely prisms of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this invention is defined by the appended claims and their equivalents.
