Description

Technical Field

[0001] The utility model relates to the technical field of sterile product production, in particular to an isolation frame structure of a powder filling machine. Background Art

[0002] The powder-liquid dual-chamber bag is a ready-to-mix infusion product consisting of a liquid chamber containing the injection solvent and a powder chamber containing the drug powder. The two chambers are separated by a weakly welded divider. During use, medical personnel simply need to gently squeeze the liquid chamber to open the weakly welded divider between the two chambers, allowing the injection solvent and drug powder in both chambers to be fully mixed.

[0003] Currently, the production of powder-liquid dual-chamber bags requires the use of powder filling machines for aseptic production. Aseptic production requires strict control of the cleanliness of raw materials, equipment, and the workshop environment to ensure the sterility of the product. During the long-term production of sterile products, temporary or planned maintenance of production equipment is inevitable. In such cases, the mechanical transmission and electrical control areas of the powder filling machine must be opened to perform maintenance on the relevant components.

[0004] However, the above maintenance operations, which are routine in ordinary factories, will have a huge impact in sterile workshops with very high cleanliness requirements, and may even destroy the clean environment. As a result, the entire equipment or even the entire workshop needs to be thoroughly cleaned and sterilized after the maintenance operation, resulting in long-term production stoppages.

[0005] Furthermore, the mechanical transmission and electrical control areas of existing powder filling machines are typically located at the bottom or in corners where ventilation is difficult. These areas are more susceptible to dust accumulation and bacterial growth, thus contaminating the sterile environment of the production area. Therefore, existing powder filling machines need improvement. Utility Model Content

[0006] In response to the problems existing in the prior art: the mechanical transmission area and electrical control area in the existing powder filling machine are prone to contamination of the sterile environment of the production area. The purpose of this utility model is to provide an isolation frame structure for a powder filling machine. By effectively isolating the mechanical transmission area and electrical control area in the powder filling machine while meeting production needs, the equipment can maintain a highly sterile production environment during maintenance, avoiding long-term production stoppages due to comprehensive cleaning and sterilization, which is conducive to improving production efficiency.

[0007] In order to achieve the above-mentioned purpose, the technical solution of the utility model is:

[0008] A powder filling machine isolation frame structure is provided. The powder filling machine is provided with a clean production area, a mechanical transmission area, and an electrical control area. The clean production area is located above the mechanical transmission area and the electrical control area. The isolation frame structure includes a maintenance box and a partition plate. The mechanical transmission area and the electrical control area are both enclosed in the maintenance box. The clean production area is located above the partition plate, and the maintenance box is arranged below the partition plate.

[0009] The utility model is further configured to include an isolation pipe, which is used to connect the maintenance box and the clean production area.

[0010] The utility model is further configured as follows: the clean production area includes a closed aseptic isolation system and an open aseptic isolation system, and the isolation pipeline connects the maintenance box and the open aseptic isolation system.

[0011] The present invention is further configured as follows: the isolation pipe vertically passes through the partition plate, and a cover plate and a cable channel are provided on the isolation pipe, the cover plate is used to cover the top pipe opening of the isolation pipe, and the cable channel is located on the side wall of the isolation pipe.

[0012] The utility model is further configured as follows: the open aseptic isolation system includes a feed end and a discharge end, and the feed end and the discharge end are respectively located on both sides of the closed aseptic isolation system.

[0013] The utility model is further configured as follows: the maintenance box body is provided with an openable operating door.

[0014] The utility model is further configured as follows: the maintenance box body is provided with a plurality of independently openable operating doors, and the plurality of operating doors are all provided on the same side of the maintenance box body.

[0015] The utility model is further configured as follows: the operating door is located on the side wall of the maintenance box.

They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or components referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limiting the present application.

[0025] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.

[0026] As attached Figure 1 As shown, an isolation frame structure of a powder filling machine includes a maintenance box 3, a partition plate 4 and an isolation pipe 5.

[0027] The powder filling machine is an existing mature equipment, which is equipped with a clean production area, a mechanical transmission area, and an electrical control area. Generally speaking, the clean production area of ​​the powder filling machine is located directly above the mechanical transmission area and the electrical control area.

[0028] The clean production area includes a closed sterile isolation system 1 and an open sterile isolation system 2. Sterile isolation systems, also called restricted access barrier systems (RABS), are physical partitions in the prior art that partially isolate the sterile process area from the surrounding environment to provide protection for the sterile process area. RABS are mainly of two types: open (O-RABS) and closed (C-RABS). O-RABS is non-sealed, and its sterile core area can be operated through a glove box, which can reduce personnel interference and potential contamination risks. C-RABS is fully enclosed and has an independent air purification system, which can better isolate people from the operating environment. The closed sterile isolation system 1 in the utility model has an independent air purification system, and the open sterile isolation system 2 is equipped with a high-efficiency filter.

[0029] The open sterile isolation system 2 includes a feed end 21 and a discharge end 22, and the feed end 21 and the discharge end 22 are respectively located on either side of the closed sterile isolation system 1. The open sterile isolation system 2 is in close contact with the closed sterile isolation system 1 and is combined into a whole, thereby effectively ensuring a sterile environment during the production process.

[0030] The open aseptic isolation system 2 further includes a protective door 23 that can be opened and closed, thereby facilitating production operations of workers.

[0031] The partition plate 4 is a rectangular plate structure, which is horizontally arranged between the clean production area and the mechanical transmission area and electrical control area of ​​the powder filling machine, thereby separating the clean production area with cleanliness requirements from the mechanical transmission area and electrical control area that are prone to contamination.

[0032] The mechanical transmission area and the electrical control area are located below the partition plate 4 , and a maintenance box 3 is provided on the periphery of the mechanical transmission area and the electrical control area.

[0033] The maintenance box 3 is a rectangular parallelepiped structure, which is used to accommodate mechanical parts, electrical components and cables in the mechanical transmission area and the electrical control area, and to enclose these structures that are likely to cause pollution to the production area inside the maintenance box 3.

[0034] The maintenance box 3 is provided with a plurality of independently openable operating doors 31 , and maintenance personnel can repair and maintain the equipment circuits inside the maintenance box 3 by opening the operating doors 31 .

[0035] All operating doors 31 are arranged on the side walls of the maintenance box 3. In this embodiment, the four operating doors 31 are arranged on the same side of the maintenance box 3 in the length direction, and an operating door 31 is also provided at the end of the maintenance box 3, so as to facilitate maintenance personnel to perform maintenance work on mechanical equipment or electrical circuits at any position in the maintenance box 3.

[0036] The isolation pipe 5 is a cylindrical tubular structure used to connect the maintenance box 3 and the open sterile isolation system 2. Specifically, the isolation pipe 5 is vertically arranged and passes through the partition plate 4, so that the bottom end of the isolation pipe 5 extends into the maintenance box 3 and the top extends into the open sterile isolation system 2.

[0037] The isolation duct 5 is provided with a cover plate 51 and a cable channel 52. The cover plate 51 is disc-shaped, with a diameter larger than that of the isolation duct 5, and is used to cover the top opening of the isolation duct 5. The cable channel 52 is a notch opened in the side wall of the isolation duct 5 and can be a square hole or a round hole.

[0038] In actual use, the cables in the maintenance box 3 enter the sterile isolation system through the isolation pipe 5 and finally pass through the cable channel 52. The cover 51 protects the isolation channel, allowing the electrical cables to pass through while also preventing foreign particles from passing through, thereby preventing direct contamination between the maintenance box 3 and the clean production area.

[0039] The implementation principle of the above embodiment is:

[0040] The isolated frame structure of the powder filling machine separates the clean production area from the mechanical transmission and electrical control areas by providing a partition 4 between the two, preventing them from contaminating the sterile production environment. Furthermore, the entire mechanical transmission and electrical control areas are enclosed within a maintenance box 3, preventing dust accumulation and bacterial growth, further reducing the possibility of contamination of the clean production area.

[0041] Although preferred embodiments of the present invention have been described, those skilled in the art may make additional changes and modifications to these embodiments once they are aware of the basic inventive concepts. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention. Clearly, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, to the extent such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to encompass such changes and modifications.
