Description

Technical Field

[0001] This utility model relates to the technical field of pharmaceutical preparation preservation devices, and in particular to a sterile preservation device for pharmaceutical preparations. Background Technology

[0002] In pharmaceutical preparation storage, it is necessary to ensure that the drugs are always kept in a sterile environment to prevent deterioration, while also ensuring that the drugs can be easily accessed and placed to improve operational efficiency.

[0003] However, existing drug preservation devices have significant shortcomings: due to the lack of dedicated sealing and protection mechanisms, most devices use simple caps or single-layer seal designs, which can easily allow external bacteria and moisture to seep into the box, causing drug contamination and deterioration. In addition, some devices rely on bolts to fix the sealing cap, making opening and closing operations cumbersome and inefficient when used in scenarios with frequent drug retrieval. If negative pressure preservation is required, additional equipment is needed, resulting in poor compatibility. Furthermore, existing devices lack pop-out drug bottle storage mechanisms, so drug bottles are often directly stacked or fixed deep inside the box. When retrieving them, hands must be inserted into the box, which can easily lead to contact with other drug bottles or contamination of the sterile environment inside the box. Moreover, the lack of an independent sealing structure means that retrieving one drug can expose other drugs, further increasing the risk of contamination. Additionally, retrieving drug bottles deep inside the box is difficult and prone to collisions and tipping, leading to drug leakage.

[0004] Therefore, those skilled in the art have provided a sterile preservation device for pharmaceutical preparations to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide a sterile preservation device for pharmaceutical preparations. Through a specially designed sealing mechanism, multiple sealing elements isolate external bacteria, dust, and moisture. An elastic locking mechanism allows for quick opening and closing of the sealing cap and secure fixation. Simultaneously, a pop-out drug bottle storage mechanism facilitates easy access to and from the bottles, reducing hand contact with the sterile environment and minimizing the risk of contamination. A separate sealing cover and cam-based fixing structure prevent the exposure of other drug bottles during handling, ensuring stable placement and preventing spillage. This combination allows the sterile preservation device for pharmaceutical preparations to achieve both strict sterility protection and convenient access, meeting the dual requirements of sterility and practicality in pharmaceutical preparation preservation.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A sterile preservation device for pharmaceutical preparations includes a preservation box and a sealing cap, wherein a sealing protection mechanism is provided between the preservation box and the sealing cap, and a pop-out drug bottle preservation mechanism is provided inside the preservation box.

[0008] The sealing protection mechanism includes two upper limit plates, which are fixedly connected to the lower part of the outer walls on both sides of the sealing cover. Lower limit plates are fixedly connected to the upper part of the middle of the outer walls on both sides of the storage box. The upper end face of each of the two lower limit plates is provided with an assembly port. The lower end face of each of the two upper limit plates is fixedly connected with an assembly column. An adjustment groove is provided on the opposite side of each of the two assembly columns. A return spring is fixedly connected to the inner wall of one side of each of the two adjustment grooves. A movable seat is fixedly connected to the opposite end of each of the two return springs. A locking rod is fixedly connected to the opposite side of each of the two movable seats. A locking hole is provided on the opposite side of each of the two lower limit plates. The locking rod is locked in the locking hole.

[0009] Through the above technical solution, a sealing base structure with elastic locking and precise fixation can be constructed through the sealing protection mechanism. When the assembly column is inserted into the assembly port, the locking rod is squeezed and compressed to return the spring. After full insertion, the spring pushes the locking rod into the locking hole, realizing the quick fixation of the sealing cover and the storage box. It can be opened and closed without tools, solving the problems of traditional devices that rely on bolt fixation and are cumbersome to operate. It is suitable for scenarios where drugs are frequently taken out and put in. At the same time, the locking fixation ensures that the sealing cover is not easy to loosen, providing a stable foundation for subsequent multiple sealing.

[0010] Furthermore, the pop-out medicine bottle storage mechanism includes two sealing covers and multiple limiting grooves. A fixed column is fixedly connected to the center of the lower inner wall of the storage box. Reset grooves are provided on the lower outer walls of both sides of the fixed column and on the lower inner walls of both sides of the storage box. Limiting slide rods are fixedly connected between the upper and lower inner walls of the multiple reset grooves. Auxiliary springs are movably sleeved on the lower outer walls of the multiple limiting slide rods. Movable sleeve columns are movably sleeved at the middle of the outer walls of the multiple limiting slide rods. A connecting plate is fixedly connected between two movable sleeve columns on the same side. Mounting seats are fixedly connected to the upper end faces of the two connecting plates. Placement grooves are provided on the upper end faces of the two mounting seats. Medicine preparation bottles are movably sleeved in the two placement grooves.

[0011] The above technical solution allows for the construction of a medicine bottle storage structure using a pop-out medicine bottle storage mechanism. An auxiliary spring supports the mounting base via a movable sleeve and connecting plate. After the medicine bottle is placed in the placement slot, the elasticity of the auxiliary spring buffers the impact during placement, preventing damage from collisions. Furthermore, the cooperation between the limiting slide rod and the movable sleeve ensures smooth lifting and lowering of the mounting base, preventing the medicine bottle from tipping over and leaking. This solves the problem of traditional devices where medicine bottles are easily tipped over when directly stacked, while also providing structural support for the subsequent pop-out retrieval function.

[0012] Furthermore, the two sealing covers are respectively fitted onto the upper end face of the corresponding drug preparation bottle, and cams are rotatably connected to both sides of the upper end face of the two sealing covers. Restriction grooves are provided on the upper part of the outer walls on both sides of the fixing column and on the upper part of the inner walls on both sides of the storage box. The cams are fitted into the restriction grooves, and a torsion head is fixedly connected to the center of the upper end face of the cams.

[0013] The above technical solution isolates external contamination by locking the upper part of the medicine bottle with a sealing cover. Rotating the twisting head causes the cam to engage with the limiting groove, which fixes the position of the sealing cover and the mounting base, preventing the mounting base from accidentally popping out. When taking out or putting out medicine, simply rotate the cam to unlock it, avoiding the exposure of other medicine bottles when taking out or putting out one medicine bottle. This solves the problem of traditional devices lacking independent sealing and being prone to cross-contamination, further ensuring the sterility of medicines.

[0014] Furthermore, the lower end faces of the two assembly columns are fixedly connected to limit plates, and the lower inner walls of the two assembly ports are provided with limit slots, and the limit plates are engaged in the limit slots.

[0015] Through the above technical solution, after the assembly column is inserted, the limiting plate engages with the limiting slot, restricting the up and down movement of the assembly column. This prevents the assembly column from shifting during device handling or vibration, causing the locking rod to disengage from the locking hole. It also avoids the sealing cover from loosening and causing sealing failure, ensuring the long-term stability of the sealing structure and reducing the risk of drug contamination.

[0016] Furthermore, the upper and lower end faces of the movable seat are fixedly connected to limit sliders, and the inner walls of the upper and lower ends of the adjustment groove are provided with limit grooves, and the limit sliders are slidably disposed in the limit grooves.

[0017] With the above technical solution, when the moving seat drives the locking rod to move, the limiting slider slides along the limiting groove to prevent the moving seat from tilting and causing the locking rod to deviate. This ensures that the locking rod can be accurately aligned with the locking hole, avoids failure of the sealing cover due to misalignment, ensures the reliable operation of the sealing protection mechanism, and reduces operational errors.

[0018] Furthermore, a sealing gasket is fixedly connected to the lower end face of the sealing cover, and the sealing gasket is movably fitted inside the storage box.

[0019] By using the above technical solution, the sealing gasket is attached to the inner wall of the storage box to fill the tiny gap between the sealing cover and the box, which can prevent external bacteria and moisture from seeping in from the gaps in the inner wall. This solves the problem of traditional devices relying only on edge sealing and easy leakage of the inner wall, further improving the overall sealing effect of the device and ensuring a sterile environment inside the box.

[0020] Furthermore, an annular sealing ring is fixedly connected to the lower end face of the sealing cover, and an annular sealing groove is provided on the upper end face of the storage box, with the annular sealing ring fitted into the annular sealing groove.

[0021] The above technical solution uses an annular sealing ring inserted into an annular sealing groove to form a surrounding sealing structure, which blocks external contaminants from entering from the edge of the device. This solves the problem of easy failure of the single seal in traditional devices, greatly reduces the probability of drug contamination, and meets the requirements for strict aseptic preservation.

[0022] Furthermore, an air extraction connector and a one-way valve are fixedly fitted on one side of the storage box, a viewing window is fixedly fitted on the front end of the storage box, and a handle is fixedly connected to the upper end of the sealing cover;

[0023] The above technical solution improves the sterile preservation and usage functions of the device by using an air extraction connector, a one-way valve, and a viewing window. The air extraction connector can connect to the device to extract air from the chamber to achieve negative pressure preservation. The one-way valve prevents air backflow from disrupting the negative pressure environment, further enhancing the sterile preservation effect. The viewing window allows for easy observation of the drug status inside the chamber without opening the sealed cover, reducing the risk of contamination caused by opening the cover. This solves the problems of traditional devices lacking negative pressure function and inconvenient observation, thus improving the practicality of the device.

[0024] This utility model has the following beneficial effects:

[0025] 1. The present invention proposes a sterile preservation device for pharmaceutical preparations. Through the addition of a sealing protection mechanism and a multi-seal design, it can effectively isolate external bacteria, dust and moisture from entering the preservation box, solving the problem of pharmaceutical preparations being contaminated and deteriorated due to poor sealing in traditional preservation devices. It ensures the sterility of pharmaceutical preparations, extends the shelf life, and the elastic locking structure allows for quick opening and closing of the sealing cap without tools. It is convenient to operate and suitable for scenarios where drugs are frequently taken out and put in. At the same time, the locking and fixing and the limiting plate provide double reinforcement to prevent the sealing cap from accidentally loosening and causing the seal to fail.

[0026] 2. The present invention proposes a sterile preservation device for pharmaceutical preparations. Through the addition of a pop-out drug bottle preservation mechanism, the elastic pop-out design avoids the need to directly reach deep into the box to retrieve drug bottles, solving the problems of inconvenience and easy collision contamination in traditional preservation devices. It reduces hand contact with the sterile environment inside the box, reducing the risk of contamination. Moreover, the sealing cover and cam fixing structure can individually seal each drug bottle, preventing other drug bottles from being exposed to the air when one drug bottle is retrieved or placed, further ensuring the sterility of the pharmaceutical preparations inside the box. The guiding effect of the mounting base and the limiting slide rod ensures that the drug bottle is placed stably, avoiding tipping and drug leakage. At the same time, the buffering effect of the auxiliary spring can reduce the impact during placement and protect the integrity of the pharmaceutical preparation bottle.

[0027] 3. The sterile preservation device for pharmaceutical preparations proposed in this utility model, through its sealing and protection mechanism, uses a multi-layer sealing design to isolate external bacteria, dust, and moisture. The elastic locking mechanism allows for quick opening and closing of the sealing cap and secure fixation. Simultaneously, the pop-out drug bottle preservation mechanism facilitates easy access to and from the bottles, reducing hand contact with the sterile environment inside the box and lowering the risk of contamination. The separate sealing cover and cam-fixing structure prevent other drug bottles from being exposed during handling, while ensuring stable placement of the bottles and preventing tipping and leakage. The combination of these features allows the sterile preservation device for pharmaceutical preparations to achieve both strict sterility protection and convenient access, meeting the dual requirements of sterility and practicality for pharmaceutical preparation preservation.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Reference Figure 1 , Figure 2 , Figure 3 and Figure 6 This utility model provides a specific embodiment: a sterile preservation device for pharmaceutical preparations, including a preservation box 1 and a sealing cover 2. A sealing protection mechanism 5 is provided between the preservation box 1 and the sealing cover 2. A pop-out drug bottle preservation mechanism 6 is provided inside the preservation box 1. An air extraction connector 7 and a one-way valve 8 are fixedly sleeved on one side of the preservation box 1. A viewing window 3 is fixedly sleeved on the front end of the preservation box 1. A handle 4 is fixedly connected to the upper end of the sealing cover 2. The sterile preservation and use functions of the device are improved by the air extraction connector 7, the one-way valve 8 and the viewing window 3. That is, the air extraction connector 7 can be connected to the equipment to extract air from the box to achieve negative pressure preservation. The one-way valve 8 prevents air backflow from destroying the negative pressure environment, further improving the sterile preservation effect. The viewing window 3 makes it easy to observe the state of the drugs in the box. The situation can be understood without opening the sealing cover 2, reducing the risk of contamination caused by opening the cover. This solves the problems of traditional devices not having negative pressure function and inconvenient observation, and improves the practicality of the device.

[0038] The sealing protection mechanism 5 includes two upper limit plates 501, which are fixedly connected to the lower part of the outer walls on both sides of the sealing cover 2. Lower limit plates 502 are fixedly connected to the upper part of the middle of the outer walls on both sides of the storage box 1. Assembly ports 504 are provided on the upper surfaces of both lower limit plates 502. Assembly columns 503 are fixedly connected to the lower surfaces of both upper limit plates 501. Adjustment grooves 505 are provided on opposite sides of both assembly columns 503. Return springs 506 are fixedly connected to the inner walls of one side of each adjustment groove 505. Movable seats 507 are fixedly connected to opposite ends of both return springs 506. Locking rods 508 are fixedly connected to opposite sides of both movable seats 507. The lower limit plates 502 are fixedly connected to opposite sides of each lower limit plate 502. A locking hole 509 is provided, and a locking rod 508 is locked inside the locking hole 509. Through the sealing protection mechanism 5, a sealing base structure with elastic locking and precise fixation can be constructed. That is, when the assembly column 503 is inserted into the assembly port 504, the locking rod 508 is compressed and the return spring 506 is compressed. After full insertion, the spring pushes the locking rod 508 into the locking hole 509, realizing the rapid fixation of the sealing cover 2 to the storage box 1. It can be opened and closed without tools, solving the problems of traditional devices relying on bolt fixation and cumbersome operation. It is suitable for scenarios involving frequent drug handling. At the same time, the locking fixation ensures that the sealing cover 2 is not easily loosened, providing a stable foundation for subsequent multiple seals. Limiting plates 512 are fixedly connected to the lower end faces of both assembly columns 503, and the lower ends of the two assembly ports 504... Each end of the device has a limiting slot 513 on its inner wall. A limiting plate 512 engages with the limiting slot 513. After the assembly column 503 is inserted, the limiting plate 512 engages with the limiting slot 513, restricting the vertical movement of the assembly column 503. This prevents the assembly column 503 from shifting during device handling or vibration, causing the engaging rod 508 to disengage from the engaging hole 509. This also prevents the sealing cover 2 from loosening and causing sealing failure, ensuring the long-term stability of the sealing structure and reducing the risk of drug contamination. The upper and lower end faces of the moving seat 507 are fixedly connected to limiting sliders 510. The upper and lower end inner walls of the adjusting groove 505 have limiting grooves 511. The limiting sliders 510 are slidably disposed in the limiting grooves 511. When the moving seat 507 moves the engaging rod 508, the limiting sliders 510 move along the limiting grooves 511. The limiting slide groove 511 slides to prevent the moving seat 507 from tilting and causing the locking rod 508 to shift, ensuring that the locking rod 508 can be accurately aligned with the locking hole 509. This avoids the sealing cover 2 from failing to stay in place due to misalignment, ensuring the reliable operation of the sealing protection mechanism 5 and reducing operational errors. A sealing gasket 516 is fixedly connected to the lower end face of the sealing cover 2. The sealing gasket 516 is movably fitted inside the storage box 1. By adhering to the inner wall of the storage box 1, the sealing gasket 516 fills the tiny gap between the sealing cover 2 and the box, preventing external bacteria and moisture from seeping in from the gaps in the inner wall. This solves the problem of traditional devices relying solely on edge sealing and being prone to leakage from the inner wall, further improving the overall sealing effect of the device and ensuring a sterile environment inside the box. An annular sealing ring 514 is fixedly connected to the lower end face of the sealing cover 2.An annular sealing groove 515 is provided on the upper surface of the storage box 1. An annular sealing ring 514 is fitted into the annular sealing groove 515. By engaging the annular sealing ring 514 into the annular sealing groove 515, a surrounding sealing structure is formed, preventing external contaminants from entering from the edge of the device. This solves the problem of easy failure of the single seal in traditional devices, significantly reducing the probability of drug contamination and meeting the requirements for strict aseptic preservation.

[0039] Reference Figure 2 , Figure 4 and Figure 5 The pop-out medicine bottle storage mechanism 6 includes two sealing covers 610 and multiple limiting grooves 613. A fixing post 601 is fixedly connected to the center of the lower inner wall of the storage box 1. Reset grooves 602 are provided on the lower outer walls of both sides of the fixing post 601 and on the lower inner walls of both sides of the storage box 1. Limiting slide rods 603 are fixedly connected between the upper and lower inner walls of the multiple reset grooves 602. Auxiliary springs 604 are movably sleeved on the lower outer walls of the multiple limiting slide rods 603. Movable sleeve posts 605 are movably sleeved at the middle of the outer walls of the multiple limiting slide rods 603. A connecting plate 606 is fixedly connected between two movable sleeves 605 on one side. Mounting seats 607 are fixedly connected to the upper surfaces of the two connecting plates 606. Each mounting seat 607 has a placement groove 608 on its upper surface. A medicine preparation bottle 609 is movably fitted into each of the two placement grooves 608. A medicine bottle storage structure can be constructed using a pop-out medicine bottle storage mechanism 6. Specifically, an auxiliary spring 604 supports the mounting seats 607 via the movable sleeves 605 and connecting plates 606. After the medicine bottle is placed into the placement groove 608, the elasticity of the auxiliary spring 604 buffers the impact during placement. To prevent damage from collisions to the medicine bottles, the cooperation between the limiting slide bar 603 and the movable sleeve column 605 ensures smooth lifting and lowering of the mounting base 607, preventing the medicine bottles from tipping over and leaking. This solves the problem of easy tipping when medicine bottles are directly stacked in traditional devices, and also provides structural support for the subsequent pop-out and retrieval function. Two sealing covers 610 are respectively engaged and sleeved on the upper end face of the corresponding medicine preparation bottle 609. Cams 611 are rotatably connected to both sides of the upper end face of the two sealing covers 610. Restriction grooves 613 are provided on the upper part of the outer walls on both sides of the fixed column 601 and the upper part of the inner walls on both sides of the storage box 1. Cam 611 is fitted into the limiting groove 613. A torsion head 612 is fixedly connected to the center of the upper end face of cam 611. The sealing cover 610 locks the upper end of the medicine bottle to isolate external contamination. Rotating the torsion head 612 causes cam 611 to engage with the limiting groove 613, which can fix the position of sealing cover 610 and mounting base 607 and prevent mounting base 607 from popping out accidentally. When taking out or putting out medicine, only cam 611 needs to be rotated to unlock it, avoiding the exposure of other medicine bottles when taking out or putting out one medicine bottle. This solves the problem of traditional devices not having independent seals and being prone to cross-contamination, and further ensures the sterility of medicines.

[0040] Working Principle: This aseptic preservation device for pharmaceutical preparations achieves aseptic preservation and convenient retrieval of pharmaceutical preparations through the coordinated operation of the sealing protection mechanism 5 and the pop-out drug bottle preservation mechanism 6. First, the pop-out drug bottle preservation mechanism 6 places the pharmaceutical preparation bottle 609. This is achieved by pressing the mounting base 607, causing the movable sleeves 605 of the connecting plates 606 on both sides to slide downwards along the limiting slide rod 603, compressing the auxiliary spring 604 in the reset groove 602. After placing the pharmaceutical preparation bottle 609 into the placement groove 608 of the mounting base 607, the mounting base 607 is released. The auxiliary spring 604 releases its elastic force, pushing the movable sleeves 605 and the mounting base 607 back to their original positions, thus stably placing the pharmaceutical preparation bottle 609 within the preservation box 1. Then, the sealing cover 610 is engaged. At the top of the pharmaceutical preparation bottle 609, rotate the torsion heads 612 on both sides of the sealing cover 610, causing the cam 611 to rotate and engage with the fixing post 601 and the limiting groove 613 on the inner wall of the storage box 1, fixing the position of the sealing cover 610 and achieving independent sealing of a single pharmaceutical preparation bottle 609 to prevent cross-contamination. Then, the sealing protection mechanism 5 completes the overall aseptic sealing of the storage box 1. Hold the handle 4 of the sealing cap 2, align the sealing cap 2 with the storage box 1, align the assembly post 503 of the upper limit plate 501 with the assembly port 504 of the lower limit plate 502, and at the same time align the annular sealing ring 514 at the lower end of the sealing cap 2 with the annular sealing groove 515 at the upper end of the storage box 1. Press down on the sealing cap 2, and during the process of the assembly post 503 being inserted into the assembly port 504, the sealing cap 610 is engaged. When the clamping rod 508 is pressed against the inner wall of the assembly port 504, it pushes the moving seat 507 to compress the return spring 506. When the assembly column 503 is fully inserted into the assembly port 504, the limiting plate 512 at the lower end of the assembly column 503 engages with the limiting groove 513. The clamping rod 508 aligns with the clamping hole 509 and engages under the action of the return spring 506, thus completing the fixation of the sealing cover 2 to the storage box 1. At this time, the sealing gasket 516 at the lower end of the sealing cover 2 is tightly attached to the inner wall of the storage box 1, and the annular sealing ring 514 engages with the annular sealing groove 515, forming a preliminary seal. The air is then extracted through the air extraction connector 7 to create a negative pressure environment inside the box, further improving the aseptic preservation effect. The operator can observe the condition of the medicine inside the box through the front viewing window 3 without opening the seal. The status of the medication can be checked by opening the cover 2. When the medication needs to be retrieved, first press the locking rods 508 on both sides of the lower limit plate 502 to disengage them from the locking holes 509. Pull the handle 4 upward to open the sealing cover 2. Rotate the torsion head 612 of the sealing cover 610 on the target medication bottle 609 in the opposite direction to disengage the cam 611 from the limiting groove 613. Remove the sealing cover 610, and the auxiliary spring 604 will pop out, moving the medication bottle 609 to a height that is easy to access. If continued storage is required, replace the sealing cover 610 and fix the cam 611. Then close the sealing cover 2 through the sealing protection mechanism 5. If necessary, supplement the air evacuation through the air extraction connector 7 to ensure that the box maintains a sterile negative pressure environment. The entire process ensures strict aseptic storage of the medication.This also allows for convenient handling and storage of medications, preventing contamination caused by improper operation.
