Description

Technical Field

[0001] This invention relates to the field of medical devices, and more particularly to medical containers and accessories for storing or arranging drugs, specifically an adapter and a medical container with an adapter. Background Technology

[0002] Medical containers refer to containers used to store medical devices, medical materials, pharmaceuticals, liquid medicines, and biochemical solutions, and have closed or semi-closed openings. These containers utilize puncture-proof, movable, or adjustable structures to alter the connection between the opening and the external environment. These structures are often designed as caps or plugs that cover or snap onto the container opening. Simultaneously, the cap or plug structure must serve as a channel for inserting or removing pharmaceuticals or materials, especially for multiple uses. The ease of use, airtightness, and protection against repeated use of the cap or plug structure are crucial for maintaining pharmaceutical quality and preventing contamination. Furthermore, cap or plug structures can also serve functions such as dosage statistics, structural protection, and assisting in the injection and removal of pharmaceutical solutions / medications.

[0003] For example, a relatively economical storage method for medical containers used to store vaccines is to store several doses of vaccine in a single medical container, i.e., a single container stores multiple doses of vaccine. This setup facilitates protection and preservation during transportation. When preparing to administer the vaccine, the corresponding dose is drawn from the medical container and injected into the target body. It must be used within a specified storage condition and time frame, otherwise it will be discarded. Therefore, the medical container will undergo multiple vaccine extraction processes, and the capping structure may be exposed to contamination of the liquid or medicine inside the medical container due to multiple punctures.

[0004] For example, in biological and chemical experiments, it is often necessary to take out several doses of solution in batches from a container containing multiple doses of solution to meet the needs of repeated or comparative experiments. For example, multiple blood samples, urine samples, bacterial solutions or drug solutions may be drawn to prepare multiple experimental samples. In the skin test, multiple draws may be made from the drug solution bottle to prepare the skin test solution. Therefore, the stability of the quality and consistency of the properties of the solutions taken out in batches are very important for the experimental results.

[0005] Therefore, adopting a reasonable structure or method to ensure the quality stability of drugs or solutions obtained by puncture in batches from containers containing multiple doses of drugs or solutions is of great significance for obtaining effective treatment results or accurate experimental results.

[0006] In the prior art, patent CN101495381B discloses a sealing cap for a container filled with medical liquid, the container having an opening sealed by a permeable membrane. The sealing cap has a cap-like closure body and a drinking nozzle with a drinking opening, the drinking nozzle being pivotable between a first position and a second position. In the first position, the drinking nozzle rests against the closure body, while in the second position, the drinking nozzle stands upright away from the closure body. This patent's technical solution provides a medical container sealing cap that is easy for patients to draw from, based on a structural design. The sealing cap establishes an adjustable connection between the rotating drinking nozzle and the interior of the container, and a venting structure balances the internal air pressure, facilitating the patient's absorption of nutritional or pharmaceutical liquids from the medical container. Patent CN107820421B also discloses a connector for a medical container. The connector includes a connector element that connects to the medical container to provide a port to the medical container. The connector element includes a head and a clamping portion adjacent to the head. The head includes an opening, and the clamping portion encloses an inner cavity that is fluidly connected to the opening of the head to provide a fluid path through the connector element. The clamping portion is flexibly deformable to clamp the fluid path through the connector element. The technical solution of this patent provides a head arranged at the connection position of the medical container. The head is provided with a deflection element that limits the puncture range, which significantly reduces the risk of damaging the clamping portion of the connector element during the puncture process.

[0007] Patent CN104220038B discloses an adapter for connection to a medical container. The adapter includes a tubular body receiving a puncturable elastic element that defines an internal lumen of the adapter. The puncturable elastic element is movable within the tubular body between the first position and the second position, proximally spaced from the first position. In the first position, a distal portion of the puncturable elastic element forms a seal of the lumen, and in the second position, the distal portion opens the seal of the lumen. This patent provides a solution that ensures the spacer remains sterile during injection or throughout the lifespan of a multi-dose vial, and prevents drug waste even if the multi-dose vial is not stored under sterile conditions. The patent with announcement number CN103565646B provides a dosage counting device for connection with medical containers. This device can perform dosage statistics on the internal liquid of a medical container containing multiple doses to guide injection operations. In the case of multiple retrievals, the device can also ensure that the internal liquid is in a sterile state based on the design of the clamping part and the cover to avoid drug waste.

[0008] Based on the above analysis, existing technologies for adjusting the isolation / connection state between the internal and external environments of medical containers have set up various medical container cap structures for structural protection, sealing and cleaning, and functional assistance. Generally, the injection device used to extract the liquid medicine inside the medical container needs to puncture the cap structure or membrane structure of the sealed medical container. However, due to the structural setting of the cap opening, existing technologies rarely involve adjusting the puncture point to reduce the risk of cross-infection caused by syringe exposure. This is especially true for medical containers that require multiple punctures to extract the liquid medicine. In other words, the puncture path in the existing technology is relatively simple under the limitation of the cap structure. Repeated puncture paths increase the risk of cross-infection of the syringe and contamination of the liquid medicine. Continuous punctures at the same location will continuously damage the cap structure or membrane structure, resulting in a decrease in sealing effect or even sealing failure.

[0009] In addition, existing devices for measuring and counting medical containers are mostly manual or mechanical, with few involving automatic detection and counting. This makes it inconvenient for accurate management and planning of dosage data. Furthermore, automatic detection technology is not linked to puncture path management to improve the quality of liquid extraction from multi-dose medical containers. The improvement of this liquid extraction structure and method can also be applied to the puncture and liquid extraction operation of multi-dose drug solutions in the laboratory to ensure the quality of liquid extraction.

[0010] Furthermore, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the inventors studied a large number of documents and patents when making this invention, but due to space limitations, not all details and contents were listed in detail. However, this does not mean that the present invention does not possess the features of these prior art. On the contrary, the present invention already possesses all the features of the prior art, and the applicant reserves the right to add relevant prior art to the background art. Summary of the Invention

[0011] To address at least some of the shortcomings of existing technologies, this application provides an adapter device applicable to medical containers or other types of containers requiring multiple punctures for fluid extraction. The container includes a container body, an opening, and a bottle neck. The adapter device includes: a first module for providing an auxiliary seal for the bottle neck, the first module being connected to the container in a manner that surrounds at least a portion of the opening, allowing the first module to cover the bottle neck with an auxiliary membrane disposed within the first module; and a second module for puncture point management, the second module being positioned in a direction away from the opening of the first module and connected to the first module. The module is connected, and the second module includes an adjustment surface placed on the side of the auxiliary membrane away from the bottle opening. When the adjustment surface and the second module are arranged coaxially, the adjustment surface is configured with a first plane and a second plane that cover at least a portion of the bottle opening area at different heights. When the first plane, which rotates around the axis of the adjustment surface, is provided with a radially arranged position, the puncture position for determining the puncture point is set in the direction away from the bottle opening in a manner that allows it to reciprocate in the area of ​​the second plane corresponding to the radial position, so that the adjustment surface can perform circumferential and radial adjustments of the puncture point through the radial position and the puncture position.

[0012] For medical containers holding medications, the storage conditions are extremely stringent. To prevent contamination and deterioration, the medical containers and the structures used to seal them must meet requirements regarding airtightness, water resistance, and light protection. Common medical containers are tubular or bottled. To facilitate storage or meet transportation needs, a single medical container can hold several doses of medication. Upon reaching the destination, medical personnel perform several punctures to extract the medication and administer a single dose to several patients. Due to limitations in usage scenarios or storage conditions, the intervals between punctures are difficult to control, resulting in medications or solutions not being used up in time. The repeated punctures with sharp instruments such as syringes further complicate storage by damaging the bottle's seal and increases the probability of contamination of the medication inside the container. Therefore, addressing the problem in existing technologies where puncture extraction from multi-dose medical containers is concentrated in a localized area, leading to cross-infection or seal failure, this application proposes an adapter device that provides auxiliary sealing for multi-dose medical containers and intelligently manages puncture points and dosages.

[0013] The adapter in this application is equipped with a first module for providing an auxiliary seal. The first module is arranged around the opening, so that an auxiliary membrane disposed inside the first module can cover the bottle opening. The bottle opening generally has a membrane structure or a stopper structure. When performing puncture to extract fluid, if the stopper structure is removed, the bottle opening of the medical container will be completely open, and the medication that cannot be used in time will be contaminated by air. The damage to the membrane structure under puncture is unpredictable, especially in the case of repeated punctures in a local area. Therefore, it is necessary to provide an auxiliary seal for the bottle opening to further protect the liquid inside the medical container. Specifically, the auxiliary membrane in this application can be configured to be made of an elastic material with a more prominent ability to recover its shape under puncture, so that the auxiliary membrane based on the first module covering and limiting the bottle opening can provide an auxiliary seal for the medical container. The first module provides additional sealing protection; the second module is used for managing puncture points. The second module is configured with a first plane and a second plane. The first plane can rotate around the central axis of the second module. The first plane has radial positions arranged in the radial direction. The annular surface formed by the radial positions rotating around the central axis can at least cover the bottle mouth. The second plane has puncture positions that can move back and forth in the radial direction. The puncture positions are used to define the puncture point for the current puncture operation. The radial positions can achieve circumferential adjustment of the puncture point based on rotational movement. The puncture positions can achieve radial adjustment of the puncture point based on reciprocating movement in the radial direction. The combined effect of circumferential and radial adjustment can achieve full coverage of the puncture point within the inner diameter range of the bottle mouth. This is of great significance for improving the planning, management and automatic adjustment of puncture points.

[0014] Preferably, the first module includes a lower housing arranged around the opening. A fastening ring is provided at one end of the lower housing near the container body, allowing the fastening ring, which connects to the auxiliary membrane, to be connected to the surface of the opening in an adjustable manner. When the auxiliary membrane covers the bottle opening and is subjected to the force of the fastening ring, the auxiliary membrane is divided into a flat portion covering the bottle opening and a folded portion covering the opening, depending on the coverage position. The adjustable fastening ring can fix the first module and the auxiliary membrane to the outer surface of the opening. The second module is connected to the first module, allowing the adapter to be stably positioned at the opening of the medical container, and the fastening ring also provides the auxiliary membrane with the force required to cover the bottle opening.

[0015] Preferably, the second module is configured with an upper shell connected to the lower shell. The adjustment surface is connected to an annular structure arranged inside the upper shell in a manner that allows it to rotate relative to the upper shell. When the adjustment surface and the upper shell are coaxially arranged, an openable top cover is provided at the end of the upper shell away from the lower shell. The adjustment surface is arranged inside the second module and can move relative to the inner wall of the second module. The top cover allows the second module to be sealed in a non-puncture state to prevent contamination by airborne pathogens.

[0016] Preferably, at least a portion of the first plane is provided with radial positions, and when the radial positions rotate one revolution with the first plane, the area swept by the radial positions forms an annular surface around the central axis of the first plane, such that the annular surface can cover at least a portion of the bottle opening, wherein the radius of the first plane is greater than or equal to the outer diameter of the bottle opening.

[0017] Preferably, the second plane is configured to at least cover the radial position, and the second plane is provided with an adjustment track for arranging the puncture position. The adjustment track is connected to the central axis of the adjustment surface, so that the adjustment track and the puncture position of the second plane can rotate with the first plane. At least a portion of the length of the adjustment track facing the puncture position is provided with a toothed chain, and the puncture position is configured as a ring structure with ribs or teeth on its outer surface. When the puncture position reciprocates inside the adjustment track, the puncture position contacts the adjustment track to form a first engagement point and a second engagement point. The first engagement point experiences meshing movement between the ribs or teeth and the toothed chain, and the second engagement point experiences rolling movement of the ribs or teeth relative to the fixed surface, allowing the adjustment track to perform radial adjustment of the puncture position based on forward or reverse rotation. Only one side of the toothed chain of the adjustment track meshes with the puncture position, while the other side of the puncture position rolls without slipping against the fixed surface or fixed track, allowing the puncture position to achieve radial adjustment above the defined position based on the forward or reverse rotation of the adjustment track.

[0018] Preferably, the adjustment surface is provided with a rotary motor and a rotating shaft inside the central shaft. The rotating shaft is equipped with a first output end and a second output end that are respectively connected to the first plane and the adjustment track. The first output end and the second output end can operate independently, so that the rotating shaft can control the circumferential adjustment of the radial position and the radial adjustment of the puncture position respectively.

[0019] Preferably, the adapter is equipped with a controller for automatic adjustment of puncture sites and management of dosage. The controller is connected to a puncture sensor for obtaining the number of punctures and a bottle mouth sensor for obtaining the inner diameter of the bottle mouth. The controller is connected to a rotary motor and also to an interactive device for inputting and outputting dosage information.

[0020] To achieve automatic adjustment of puncture points and intelligent dosage management, the adapter is equipped with a controller. The controller can obtain puncture operation signals and bottle opening inner diameter data, and based on this, determine the range of radial adjustment of the puncture point, ensuring that all puncture points are within the bottle opening inner diameter to avoid puncture failure. The interactive device is used for dose data input and output. After the controller obtains the total dose, it can determine the circumferential adjustment rotation interval angle and radial adjustment movement distance based on the total dose and the radial adjustment range of the puncture point. This allows the controller to preset puncture points to achieve optimal distribution of puncture points. At the same time, it can also achieve accurate management and display of dose data based on sensors and the interactive device, significantly improving the intelligent management effect of the adapter for puncture points and dose data, and greatly improving the efficiency and safety of multi-dose puncture and fluid extraction operations.

[0021] Preferably, this application provides a method for using the adapter, which is implemented based on the above-described adapter and includes the following steps:

[0022] The controller obtains the total dose input by the user based on the interactive interface and displays dose information, including at least the dose balance, on the interactive interface;

[0023] The controller obtains the inner diameter of the bottle opening based on the bottle opening sensor to determine the maximum radial dimension that the puncture position can move in the radial position. The controller controls the second output terminal of the rotary motor to drive the adjustment track to rotate and adjust the puncture position to the initial position of the radial position, wherein the initial position is at the minimum radius or the maximum radial dimension of the radial position.

[0024] The controller calculates the rotation interval angle for circumferential adjustment of the radial position and the movement distance for radial adjustment of the puncture position based on the total dose and the maximum radial dimension, so that the number of puncture points preset by the controller is not less than the total dose.

[0025] In response to the puncture completion signal from the puncture sensor, the controller performs a cyclic action of several circumferential adjustments and one radial adjustment based on the rotary motor, or the controller performs a cyclic action of several radial adjustments and one circumferential adjustment based on the rotary motor.

[0026] When the controller performs several circumferential adjustments and one radial adjustment cycle based on the rotary motor, the controller controls the first output end of the rotary motor to drive the radial position to perform circumferential adjustment to change the unit rotation interval angle. When the circumferential adjustment is completed, the controller controls the second output end of the rotary motor to drive the piercing position in the adjustment track to perform radial adjustment to change the unit movement distance, so that the controller can control the radial position to continue to perform circumferential adjustment.

[0027] When the puncture site is adjusted to different radial dimensions based on the radial adjustment movement, the controller uses different rotation interval angles for different radial dimensions, so that the rotation interval angle of the circumferential adjustment decreases as the radial dimension increases.

[0028] Preferably, this application also provides a medical container with an adapter, which performs multi-dose drug puncture and extraction operations based on the above-mentioned adapter and usage method. Attached Figure Description

Detailed Implementation

[0036] The present invention will now be described in detail with reference to the accompanying drawings.

[0037] Example 1

[0038] This application provides an adapter device, which is mainly suitable for medical containers or other types of containers that require multiple punctures for fluid extraction or injection, such as... Figure 1As shown, a medical container or other container has a container body 1, which serves as the main container for the medicine or other liquid. The container body 1 is commonly configured with a circular or polygonal cross-section. The upper part of the container body 1 tapers symmetrically or asymmetrically towards the center to form an opening 2, allowing the container body 1 to communicate with the external environment through the bottle mouth 3 provided in the opening 2. The bottle mouth 3 can serve as a channel for the medicine to enter and exit inside the container body 1. For medical containers that hold medicine, the storage conditions for the medicine are more stringent. To prevent the medicine from being contaminated and deteriorated, the medical container and the structure used to seal the medical container must meet requirements regarding airtightness, water resistance, and light protection.

[0039] Common medical containers are typically tubular or bottled. For ease of storage or to meet transport needs, a single medical container can hold several doses of medication. Upon arrival at the destination, medical personnel perform several punctures to extract the medication and administer a single dose to several patients. Due to limitations in usage scenarios or storage conditions, the intervals between punctures are difficult to control, resulting in medications or solutions not being used promptly. The repeated punctures with sharp instruments such as syringes damage the sealing structure of the bottle opening, further increasing the difficulty of preservation and the probability of contamination of the medication inside the container. For example, when used for different patients... After unpacking, all syringes are exposed to air. Compared to single-dose medical containers, the contact time between multi-dose medical containers and syringes is significantly increased. This means the cumulative exposure time of multiple syringes to air significantly increases the probability of contamination of the medication inside the container. Furthermore, when multiple syringes puncture the same or similar points on the bottle neck's sealing structure, repeated puncture paths increase the risk of cross-infection and medication contamination. Repeated punctures at the same location also continuously damage the bottle neck's sealing structure, leading to decreased sealing effectiveness or even seal failure. Therefore, the adapter device of this application addresses these problems with a corresponding structure to overcome at least some of the shortcomings of the prior art.

[0040] like Figure 1 As shown, the adapter of this application includes a first module 7 and a second module 11. The first module 7 provides an auxiliary seal for the sealing structure at the bottle opening 3, and the second module 11 manages the puncture path and performs dose counting. The second module 11 is arranged on top of the first module 7, so that the first module 7 and the second module 11 can be arranged with the bottle opening 3 in a manner that coincides with each other along the central axis 20. Figure 2As shown, the first module 7 is equipped with a lower housing 12 surrounding at least a portion of the opening 2. The lower housing 12 can be configured as a cylindrical or frustum-shaped surface surrounding the bottle mouth 3. A fastening ring 10 with an adjustable inner diameter is arranged at one end of the lower housing 12 near the container body 1. The fastening ring 10 can be adjusted in inner diameter by rotating relative to the medical container, so that the fastening ring 10 can fit tightly against the outer surface of the opening 2. To ensure the fastening effect or the ease of fastening, the fastening ring 10 can also be equipped with an elastic sealing strip on its inner surface to enhance the fastening effect and prevent the fastening ring 10 from not fitting firmly with the opening 2 or from causing unnecessary relative slippage. In addition, the fastening ring 10 can also be equipped with a one-way toothed chain similar to a cable tie. Compared with the rotating fastening ring 10, the one-way toothed chain can more easily achieve a tight fit between the fastening ring 10 and the opening 2 without loosening, making it more convenient to use and more economical.

[0041] like Figure 2 As shown, the first module 7 has an auxiliary membrane at the lower end of the lower housing 12 to close the opening of the lower housing 12. The circumferential edge of the auxiliary membrane is connected to the inner side of the fastening ring 10. When the first module 7 is fitted onto the opening 2 of the medical container, a sealing membrane or sealing plug is generally arranged at the rim 4 of the bottle mouth 3. The sealing membrane covers the rim 4 and is connected to the outer edge 5. The sealing plug is interference-fitted with the inner edge 6. The auxiliary membrane covers the sealing structure at the bottle mouth 3 and surrounds at least a part of the opening 2, so that the auxiliary membrane forms a flat part 9 covering the sealing structure of the bottle mouth 3 and a folded part 8 surrounding at least a part of the circumferential area of ​​the opening 2. The folded part 8 is connected to the fastening ring 10 and fits against the outer surface of the opening 2. The auxiliary membrane is made of an elastic material so that the force of the fastening ring 10 on the folded part 8 can keep the flat part 9 and the sealing structure of the bottle mouth 3 tightly fitted.

[0042] like Figure 3 As shown, the second module 11 is equipped with an upper shell 13 connected to the lower shell 12, so that the adapter of this application can form a semi-open structure surrounding the opening 2 of the medical container and the space above the opening 2 based on the combined action of the lower shell 12 and the upper shell 13. The upper shell 13 can also be provided with an openable top cover 26 on its upper surface, so that the upper shell 13, the lower shell 12 and the final draft form a closed structure. The openable connection between the top cover 26 and the upper shell 13 can be achieved by a flip-type structure or a push-pull structure. In the flip-type structure, the final draft and the upper shell 13 are connected by a shaft. The top cover 26 can be rotated relative to the shaft to realize the angle change between the top cover 26 and the upper surface of the upper shell 13, thereby opening or closing the space surrounded by the upper shell 13. The push-pull type refers to the top cover 26 and the upper shell 13 being connected by a sliding track, so that the top cover 26 can be opened or closed by changing the overlapping area with the upper surface of the upper shell 13.

[0043] like Figure 3 and Figure 4As shown, the second module 11 has a central shaft 20 arranged at the center of the upper housing 13. The central shaft 20 is connected to the adjustment surface 14, so that the adjustment surface 14 can cover the upper part of the planar part 9 around the central shaft 20 to control the selection and adjustment of the puncture point. The central shaft 20 and the adjustment surface 14 can be connected to the upper housing 13 by means of an annular boss suspended on the inner surface of the upper housing 13, so that the adjustment surface 14 can rotate relative to the annular boss around the central shaft 20. The central shaft 20 has a rotary motor 21 and a rotating shaft 19 arranged inside. The rotating shaft 19 is configured with a first output end 28 and a second output end 28 to output different rotation states respectively. The output end 29 can have different rotation parameters and / or rotation timing for different rotation states; the adjustment surface 14 includes a first plane 15 and a second plane 16, which are arranged around the central axis 20 and are arranged vertically with partial overlap. Specifically, the first plane 15 is connected to the first output end 28 of the rotating shaft 19, so that the first plane 15 can rotate around the rotating shaft 19 continuously or intermittently. The outer diameter of the first plane 15 is smaller than the inner diameter of the upper housing 13 and larger than the outer diameter of the bottle mouth 3, so that the first plane 15 can completely cover the flat portion 9 above the bottle mouth 3 to fill. The first plane 15 is configured with radial positions 17 arranged radially and penetrating the upper and lower surfaces of the first plane 15. The radial positions 17 serve as channels through which the syringe can pass through the first plane 15 for puncture. The radial positions 17 can cover the puncture positions of the plane 9 by rotating with the rotating shaft 19, so that the first plane 15 can control the circumferential adjustment of the puncture point through the radial positions 17. The second plane 16 is arranged on the upper part of the first plane 15. The arrangement range of the second plane 16 can at least cover the radial positions 17. The second plane 16 is configured with an adjustment rail 22 that connects to the second output end 29 of the rotating shaft 19. The range of action of the adjustment rail 22 covers the area that can be punctured. The radial position 17 and the adjusting track 22 are connected to the puncture position 18, so that the puncture position 18 can be adjusted in the radial direction under the action of the adjusting track 22. That is, the second plane 16 controls the radial adjustment of the puncture point based on the cooperation of the adjusting track 22 and the puncture position 18. The adjusting surface 14 can achieve maximum coverage of the puncture positions available on the planar part 9 through the cooperation of the first plane 15 and the second plane 16. The interval adjustment of the puncture points in the circumferential and radial directions can obviously provide more puncture point selections, which facilitates the interval liquid extraction operation of multi-dose liquid containers to ensure liquid extraction quality and avoid sealing failure or cross-infection.

[0044] Preferably, the shape and size of the radial position 17 can be adapted to the shape and size of the adjusting track 22. For example, the puncture position 18 is configured as an annular shape to mark the current position available for syringe puncture. The outer surface of the puncture position 18 is provided with ribs or teeth parallel to the central axis of the annulus. At least a portion of the length of the adjusting track 22 facing inward toward the puncture position 18 is provided with a movable toothed chain that engages with the ribs or teeth on the outer surface of the puncture position 18. The remaining length of the adjusting track 22 facing inward toward the puncture position 18 is provided with a fixed surface. During the movement of the puncture position 18 inside the adjusting track 22, the puncture position 18 and the adjusting track 22... A first mating point and a second mating point are formed. The first mating point has a rib or tooth meshing motion with the tooth chain, and the second mating point has a rib or tooth rolling relative to the fixed surface, so that the adjusting track 22 can achieve radial adjustment of the puncture position 18 based on the forward or reverse rotation of the second output end 29. The second plane 16 is arranged above the radial position 17. In order to ensure the mating adjustment of the puncture position 18 and the radial position 17 in the adjusting track 22, when the first plane 15 rotates under the action of the first output end 28, the second plane 16 rotates with the first plane 15, so that the effective range of the adjusting track 22 is always kept above the radial position 17.

[0045] Preferably, such as Figures 3 to 5 As shown, to achieve automatic adjustment of the puncture site and accurate management of the drug dosage, this application also includes a controller 24. The controller 24 is connected to the puncture sensor 23 and the bottle mouth sensor 27. The puncture sensor 23 is located on the side wall of the puncture position 18, allowing the controller 24 to obtain a signal from the puncture sensor 23 indicating that the syringe has been inserted into the puncture position 18. The bottle mouth sensor 27 is located on the lower surface of the first plane 15, allowing the controller 24 to obtain information on the inner and outer diameters of the bottle mouth 3. Figure 1 and Figure 5 As shown, the controller 24 is connected to the interactive device 25. The interactive device 25 is equipped with buttons for information input and a display screen for information output. The user can set the number of doses to be extracted according to the packaging information or capacity information and transmit it to the controller 24. The controller 24 can also transmit the current extracted dose and the remaining dose to the interactive device 25 and display it on the display screen, which facilitates dose management and resource allocation. The controller 24 is also connected to the rotary motor 21, so that the controller 24 can adjust the first output end 28 and the second output end 29 of the rotating shaft 19 according to the need for puncture point adjustment, so that the adjustment surface 14 can realize circumferential and radial adjustment of the puncture point under the action of the controller 24.

[0046] Preferably, when the adapter is placed at the opening 2 of the medical container, the fastening ring 10 is first adjusted to securely connect the lower shell 12 and the upper shell 13 to the opening 2 of the medical container. The auxiliary membrane covers the sealing device of the bottle mouth 3 and forms the flat part 9 and the folded part 8. The controller 24 controls the adapter to return to the initial state based on the input signal of the intercom 25. The initial state is to adjust the puncture position 18 to the position with the smallest radial dimension, so that the starting puncture point starts from a position close to the center of the flat part 9 or the edge of the flat part 9. The controller 24 obtains the inner diameter of the bottle mouth 3 based on the bottle mouth sensor 27. The controller 24 obtains the radially adjustable range of the puncture position 18 based on the inner diameter of the bottle mouth 3, i.e., the radial adjustment range. The controller 24 obtains the total dose in the medical container based on the intercom 25. The total number of puncture points is obtained based on the total dose. The controller 24 then calculates... The first output terminal 28 controls the rotation interval angle of the radial position 17 circumferentially adjusted and the second output terminal 29 controls the movement distance of the puncture position 18 radially adjusted, so that the preset puncture point value of the controller 24 is not less than the total number of puncture points. For example, when the medical container contains 100 doses of medicine, it means that 100 puncture points are required. Assuming that the puncture radius corresponding to the radial position 17 and the plane 9 is 20mm, the movement distance of the puncture position 18 radially adjusted can be set to 5mm, and the rotation interval angle of the radial position 17 circumferentially adjusted can be 18 degrees, so that the puncture points are arranged in sequence to form several rings with gradually increasing radii. That is, the ring radius size relative to the radial position 17 can be set to 0mm, 5mm, 10mm, 15mm, and 20mm in sequence, so that the positions of the puncture points are basically evenly distributed in the area of ​​the plane 9 that can be punctured.

[0047] Preferably, the puncture points are arranged in a series of concentric rings. For areas with smaller radial dimensions, the distance between puncture points on the same ring is significantly smaller due to the smaller circumference of the rings, compared to areas with larger radial dimensions, under the same circumferential adjustment rotation interval angle. This results in puncture points near the center of the planar portion 9 being too densely packed, which is not conducive to the uniform distribution of puncture points. Therefore, when the controller 24 obtains the total number of puncture points and the radial adjustment range of the puncture points 18, it can adopt different rotation interval angles for different radial dimensions, so that the rotation interval angle of the circumferential adjustment decreases as the radial dimension increases. For example, for radial dimensions of 0mm, 5mm, 10mm, 15mm, and 20mm, the rotation interval angles of the circumferential adjustment are 30 degrees, 25 degrees, 20 degrees, 16 degrees, and 12 degrees, respectively, making the spacing between each puncture point more even. Furthermore, the puncture points on different rings can be arranged in a staggered manner, which significantly improves the arrangement quality of the puncture points while meeting the puncture point spacing requirements.

[0048] Preferably, the controller 24 is connected to the puncture sensor 23, enabling the controller 24 to receive a signal that the syringe is inserted into the puncture position 18. When the syringe is inserted into the puncture position 18, the puncture sensor 23 is triggered and remains in a first state. When the syringe is withdrawn from the puncture position 18, the puncture sensor 23 is triggered and remains in a second state. In response to the change of the puncture sensor 23 from the first state to the second state, the controller 24 records a puncture and fluid extraction operation and transmits the signal to the interactive unit 25. The interactive unit 25 displays the current cumulative dose on the display screen. The display screen information may also include the remaining dose, total dose, and medication. Information such as material; after the current puncture and fluid retrieval operation is completed, if the circumferential adjustment of the current radial dimension is not completed, the controller 24 controls the radial position 17 and the puncture position 18 to perform circumferential adjustment based on the first output terminal 28 of the rotating shaft 19, that is, rotate the rotation interval angle under the current radial dimension; if the circumferential adjustment of the current radial dimension has reached 360 degrees, the controller 24 controls the puncture position 18 to perform radial adjustment based on the second output terminal 29 of the rotating shaft 19, that is, increase the radial dimension by one radial adjustment movement distance; so that the position of the puncture position 18 moves from the previous puncture point to the next puncture point in preparation for the fluid retrieval operation.

[0049] Preferably, the order of radial adjustment can be varied, that is, radial adjustment can be gradually adjusted from a position with a smaller radial dimension to a position with a larger radial dimension, or it can be gradually adjusted from a position with a larger radial dimension to a position with a smaller radial dimension; the order of radial adjustment and circumferential adjustment can also be varied to form a first mode and a second mode. The first mode is to perform circumferential adjustment at each radial adjustment node, that is, the position of the puncture point gradually expands outward or inward in a manner of several concentric rings; the second mode is to perform radial adjustment at each circumferential adjustment node, that is, the position of the puncture point is arranged radially without repetition and rotates and expands in accordance with the circumferential adjustment.

[0050] Example 2

[0051] For multi-dose medical containers used in clinical non-injection applications, such as containers containing disinfectant alcohol or iodine, the main method of use is to unscrew the cap and dip the swab in. However, the amount of liquid remaining inside the container has a significant impact on the convenience of the dipping operation, especially when the amount of liquid inside the container is small and the container is tall. When dipping the swab, the swab needs to be deflected with the hand to obtain an appropriate dipping depth. Therefore, in view of the above technical problems, the second module of the adapter device of this application can be configured as a structure for transferring the liquid inside the container to the bottle opening 3 or above the bottle opening 3, so as to facilitate the dipping operation by medical staff.

[0052] Specifically, the second module 11 may be equipped with an insertion part, a suction part, and a receiving part. The insertion part may be configured as a needle-like structure capable of piercing the auxiliary membrane of the first module, so that the insertion part can connect the bottom space of the container body 1 and the internal space of the second module in an adjustable insertion length manner. The insertion part is configured with a first section and a second section. The first section is connected to the internal space of the second module, and the second section is connected to the bottom space of the container body 1. The first section and the second section, configured with different radial sizes, are connected by a sliding sleeve. The sliding sleeve changes the superposition length between the first section and the second section based on the elasticity of the elastic component to change the length of the insertion part, so that the insertion part can adapt to containers of different depths. The sliding sleeve is provided with a locking device, which is provided in the suction part. The switch controls the insertion part to puncture the auxiliary membrane. Before the insertion part punctures the membrane, the locking device is turned on, so that the stacking length between the first and second sections of the insertion part does not change. After the insertion part punctures the auxiliary membrane and enters the internal space of the container body, the locking device is turned off, so that the first and second sections of the insertion part can change the stacking length through the sliding sleeve. The force that does work to overcome the elastic force of the sliding sleeve comes from the force on the second section when it contacts the bottom of the container body 1. Under the reaction of the elastic force of the sliding sleeve, the end of the second section away from the first section can maintain contact with the bottom of the container body 1. When the end of the second section away from the first section is configured with an opening with an inclined surface, a small amount of liquid medicine at the bottom of the container body 1 can enter the insertion part through the opening of the second section.

[0053] The end of the first section furthest from the second section is located outside the bottle opening 3 and connected to the inlet of the suction section. The outlet of the suction section is connected to the receiving section. The suction section draws liquid from the bottom of the container body 1 into the suction section based on the pressure difference and transfers it into the receiving section. The receiving section is configured as a semi-open concave shape with an opening, so that the bottom shape of the receiving section is more concentrated. Thus, the liquid transferred from the suction section can form a more suitable depth and concentrated shape for the cotton swab to absorb in the receiving section. The volume of liquid transferred into the receiving section can be determined according to the absorption requirements of the cotton swab. For example, the liquid absorption volume of a single dip of a cotton swab commonly used for skin surface disinfection is 5-10ml. Then, the liquid volume transferred to the receiving section by the suction section in a single suction action can be set to 7-12ml to ensure that the amount of liquid absorbed by the cotton swab is sufficient to adapt to the situation of a large area of ​​skin surface disinfection.

[0054] To reduce the cumbersome manual operation for users, the suction unit can be set to automatically suction via a motor and controller. The receiving unit also has an adjustable discharge port connected near the suction unit outlet. In response to a signal indicating that the swab has finished swabbing, the controller drives the motor to rotate, first discharging any remaining liquid in the receiving unit and then re-suctioning the single-use amount of liquid into the receiving unit based on the insertion unit. This means the suction unit operates without manual adjustment by the user, allowing for a cycle of draining and refilling the receiving unit. This significantly reduces the cumbersome manual operation for users and avoids the risk of contamination from frequent contact with the suction unit, helping to maintain the cleanliness of the adapter device. The adapter device equipped with the insertion unit, suction unit, and receiving unit is also suitable for multi-dose non-injectable medical containers in general volume conditions, significantly improving the convenience of swabbing liquid and avoiding repeated opening and unscrewing operations.

[0055] To avoid wasting liquid, the liquid discharged from the container can enter a storage chamber. The storage chamber is connected to a sprayer that is regulated and controlled by a controller, so that the liquid in the storage chamber can spray and disinfect the outer shell, top cover 26 and switch of the second module under the action of the sprayer. In response to the signal that the number of times the cotton swab has been dipped has reached the set value, the sprayer draws the liquid in the storage chamber and sprays it under the action of the motor.
