[0042] The present invention will be described more clearly and completely below by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the following embodiments.

[0043] Please combine Figure 1 and Figure 2For understanding, the utility model provides a drug packaging component, which includes a cylindrical member 1, wherein both ends of the cylindrical member 1 are respectively provided with a feed port 11 and a discharge port 12 which are interconnected, and the interior of the cylindrical member 1 is provided with a drug storage cavity 13, and the drug storage cavity 13 is used to place solid drugs; the cylindrical member 1 is provided with a piston 14 near the feed port 11, and the piston 14 is detachably connected to the cylindrical member 1, and the outer peripheral wall of the piston 14 matches the inner peripheral wall of the cylindrical member 1, and the piston 14 is configured to slide relative to the cylindrical member 1. The medicine storage cavity 13 of the cylindrical member 1 is filled with pre-prepared solid medicine, the connection between the piston 14 and the cylindrical member 1 is released, the feed port 11 is opened, the solvent (such as water) is introduced into the medicine storage cavity 13 through the feed port 11, and a medicine solution, suspension or gel is formed by simple shaking, the piston 14 is installed at the feed port 11, and the piston 14 is pushed to move in the direction close to the feed port 11, so that the solution, suspension or gel is released from the discharge port 12, and then the medicine can be administered to the administration site. The solid medicine can be a dry tablet, granule, powder, low-temperature dried product or extract paste, including a freeze-dried product.

[0044] In this embodiment, the solid medicine and the solvent are mixed and formulated into a solution, suspension or gel before use for administration. On the one hand, since the active ingredients in the form of dry solid particles or powders are usually more stable than those in the form of solutions, suspensions or gels, including physical stability, chemical stability and biological stability, they are durable in storage and do not require the addition of a large amount of stabilizers, and can avoid the addition of preservatives, antioxidants, thickeners and suspending agents, thereby extending the shelf life of the product, reducing the complexity of the formula, saving costs, and improving the safety of medication; on the other hand, the solid form of the drug occupies a smaller volume, which is convenient for storage and transportation; on the third hand, the solvent is directly introduced into the drug storage chamber 13 through the feed port 11, and the drug for administration can be formed after simple shaking, and the drug administration can be achieved by pushing the piston 14, which is convenient to operate and can enable patients to administer the drug by themselves.

[0045] In this embodiment, a one-way valve 15 is installed in the middle of the piston 14, and the one-way valve 15 is configured to be able to introduce the solvent into the drug storage chamber 13. The one-way valve 15 installed at the feed port 11 can directly introduce the solvent, without releasing the connection between the piston 14 and the cylindrical member 1 when introducing the solvent, which is convenient for operation; and in the process of introducing the solvent, it is prevented that the solvent flows out from the feed port 11, thereby destroying the drug administration environment; in the process of drug administration, that is, in the process of pushing the piston 14 to push the configured solution, suspension or gel out of the discharge port 12, it is prevented that the drug flows out from the feed port 11 and affects the drug administration effect. Specifically, the piston 14 is provided with a mounting hole, and the one-way valve 15 is mounted on the piston 14 through the mounting hole.

[0046] In this embodiment, if Figure 2As shown, the one-way valve 15 includes a liquid channel 151 and an exhaust hole 152 arranged at intervals, the liquid channel 151 is configured so that the solvent enters the medicine storage cavity 13 through the liquid channel 151, and the exhaust hole 152 is located at the outer peripheral side of the liquid channel 151. While the solvent is introduced into the medicine storage cavity 13 through the liquid channel 151, the gas in the medicine storage cavity 13 can be discharged from the exhaust hole 152, and the excess gas in the medicine storage cavity 13 is discharged through the exhaust hole 152, so that the solvent is smoothly introduced.

[0047] In this embodiment, there are multiple exhaust holes 152, which are evenly spaced around the circumference of the liquid channel 151, so that excess gas in the drug storage cavity 13 can be evenly discharged from the feed port 11. In other embodiments, there is only one exhaust hole 152.

[0048] In this embodiment, the drug packaging assembly further includes a pusher (not shown in the figure), which is mounted on the side of the piston 14 away from the discharge port 12, and the pusher presses the piston 14 toward the drug storage chamber 13. The piston 14 is pushed toward the drug storage chamber 13 by the pusher, so that the prepared solution, suspension or gel in the drug storage chamber 13 can be discharged from the discharge port 12, which is convenient for operation. Specifically, the pusher abuts against the side of the piston 14 away from the discharge port 12 and covers the exhaust hole 152, so as to prevent the solution in the drug storage chamber 13 from flowing out of the exhaust hole 152 during the process of pushing the piston 14.

[0049] In this embodiment, the pusher is a push rod, a pump or a cylinder. The push rod, pump or cylinder is used as a pusher to realize the linear movement of the piston 14, which has high reliability. Among them, when the push rod is used as the pusher, the push rod can be set as an integral part with the piston 14; the push rod can also be set separately from the piston 14. When medication is required, the push rod is abutted against the side wall of the piston 14 away from the discharge port 12, thereby pushing the piston 14 to move in the direction close to the discharge port 12. When a pump is used as a pusher, the pump is clamped with the piston 14, and the linear movement of the piston 14 is realized after the pump is started.

[0050] Of course, in other examples, as an alternative means, the pusher may adopt other devices for applying pressure to make the piston 14 output movement along the axis direction of the cylindrical member 1 .

Aseptic process can be implemented, such as irradiation or ultraviolet light sterilization process, to effectively control the contamination of microorganisms during the shelf life of the product. Of course, in other embodiments, the material of the tubular member 1 can be selected from other current drug packaging materials.

[0059] The solid medicine in the medicine packaging component in this embodiment can be traditional Chinese medicine, chemical medicine, microbial preparation or biological preparation, preferably a medicine for anorectal and gynecological system diseases to achieve cavity administration.

[0060] In the specific implementation, the outer packaging is removed, the cylindrical member 1 is taken out, the first sealing member installed at the feed port 11 is removed, and the solvent is pushed into the one-way valve 15 through a syringe or other drug storage device, so that the solvent can be introduced into the drug storage cavity 13, and the solvent can be mixed with the solid drug by simple shaking to form a solution, suspension or gel to be used. The second sealing member installed at the discharge port 12 is removed, the drug delivery pipeline is connected with the connecting member 16, and the pusher is abutted against the piston 14 and pushes the piston 14 to move in the direction close to the discharge port 12, so that the solution, suspension or gel prepared in the drug storage cavity 13 is delivered to the drug delivery pipeline through the discharge port 12, so as to realize the combination of drug packaging and drug delivery device, and avoid the drug transfer process.
