Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a dialysis concentrate preparation device. Background Technology

[0002] The principle of online dialysate preparation in hemodialysis machines is as follows: A metering pump draws in concentrates A and B in specific proportions and mixes them with reverse osmosis water to generate dialysate of the required concentration. Because a chemical reaction occurs and precipitates form after the A and B concentrates are mixed and left for a period of time, the dialysate concentrate is usually separated into A and B components, which are then drawn into the machine separately, mixed with reverse osmosis water, and used for treatment.

[0003] Currently, there are three main sources of sodium bicarbonate (B) concentrate: 1. Manual preparation using dialysis dry powder; 2. Direct preparation by the manufacturer; 3. Online preparation using B dry powder. Manual preparation of B dry powder requires a dedicated preparation room and sterilization and maintenance of the equipment, resulting in high labor costs. Manufacturer-produced concentrates are expensive to transport and store, and are prone to bacterial growth, making long-term storage inconvenient. Online preparation of B dry powder involves placing the powder in a special container and installing it on the dialysis machine to prepare a saturated sodium bicarbonate solution for machine use. This method is convenient, eliminates the need for manual preparation, and facilitates transportation and storage, while also preventing bacterial growth. Sodium bicarbonate (A) concentrate is mainly sourced in two ways: 1. Manual preparation using dialysis dry powder; 2. Direct preparation by the manufacturer. The disadvantages of both methods are the same as those mentioned for B dry powder.

[0004] To address the shortcomings of existing technologies, numerous improvements have been made to dialysis concentrate preparation devices in this field. For example, the applicant has filed a patent application with publication number CN221384594U entitled "A Dialysis Concentrate Preparation Device," which includes: a body with a movable cover, the body having an upwardly inclined guide section; a pipeline interface module, vertically movable and disposed on the body and connected to the cover, the pipeline interface module having a first channel for communication with an external device; a loop interface module, movably disposed on the body, the loop interface module having a second channel, which, when connected to the first channel, forms a sterilization loop; a storage container, which can be hung on the guide section and slid along it to push the loop interface module to move longitudinally; the storage container having a third channel communicating with its inner cavity, which, when connected to the first channel, forms a preparation loop.

[0005] The aforementioned patent discloses an online preparation device for A dry powder and B dry powder for blood purification. This technical solution can, on the one hand, connect A dry powder and B dry powder simultaneously or separately to a hemodialysis machine for online preparation of concentrated solution. On the other hand, when the dry powder mechanism is removed, the machine's own cleaning and disinfection function can be used to clean and disinfect the channels and interfaces inside the preparation mechanism.

[0006] Although the aforementioned patents have solved the problems of complex structure and inconvenient operation in the prior art, they still have certain defects. For example, the cover is prone to collision with the main body during the flipping process, causing the main body to be bumped or worn; the frictional resistance between the pipeline interface module and the main body is large, resulting in difficulty in opening the cover and easy wear of the device; concentrated liquid crystals are prone to precipitate at the interface of the loop interface module; the torsion spring on the cover is exposed and prone to rust; and the misalignment between the loop interface module and the pipeline interface module during docking affects the normal closing of the cover. Utility Model Content

[0007] The purpose of this invention is to provide a dialysis concentrate preparation device that solves at least one technical problem mentioned in the background art, such as limiting the degree of flipping of the cover during the flipping process, thereby preventing the cover from directly colliding with the body and causing structural damage, and extending the service life of the device.

[0008] To achieve the above objectives, this utility model proposes a dialysis concentrate preparation device, comprising a main body, a cover, a pipeline interface module, and a loop interface module. The top of the cover is hinged to the upper end of the main body; the pipeline interface module is located above the loop interface module, and both the pipeline interface module and the loop interface module are movably connected to the main body, with the pipeline interface module hinged to the cover via a connecting rod; it also includes a hook assembly for suspending a storage container located below the loop interface module. When the hook assembly suspends the storage container, the storage container can push the loop interface module to slide along the interior of the main body.

[0009] It also includes a limiting component set on the top of the pipeline interface module and a fixing component set on the upper end of the main body; during the process of the cover flipping upward, the limiting component moves upward to abut against the fixing component, thereby limiting the cover from continuing to flip backward and collide with the main body.

[0010] Furthermore, it also includes a slide rail set between the main body and the pipeline interface module. During the flipping process of the cover, the pipeline interface module moves vertically on the main body along the slide rail.

[0011] Furthermore, the top of the loop interface module is provided with two guide channels for draining liquid leaking from the pipeline interface module. Both guide channels are inclined, and the end of the guide channel near the middle of the loop interface module is higher than the other end. A water receiving tray is also provided on the main body below the lower end of the guide channel.

[0012] Furthermore, the loop interface module includes a helical spring, one end of which is connected to the main body and the other end of which is connected to the loop interface module. A guide tube is provided on the main body, and a guide groove matching the guide tube is provided on the loop interface module. The guide tube is sleeved on the outside of the helical spring, with one end of the guide tube fixed on the main body and the other end suspended in the guide groove. After the discharge container is configured, as the loop interface module slides along the inside of the main body, the guide tube enters the guide groove, and the helical spring is compressed.

[0013] Furthermore, the bottom of the pipeline interface module is provided with a snap-fit ​​groove; the top of the loop interface module is provided with a snap-fit ​​block that matches the snap-fit ​​groove, and the longitudinal section of the upper part of the snap-fit ​​block is triangular, bullet-shaped or teardrop-shaped; when the cover is in place, the snap-fit ​​block is embedded in the snap-fit ​​groove.

[0014] Furthermore, the width of the snap-fit ​​groove is 3 / 5 to 3 / 4 of the bottom width of the pipeline interface module, and the snap-fit ​​block and the snap-fit ​​groove are fitted with a clearance.

[0015] Furthermore, a torsion spring is provided at the connection between the cover and the main body, and a protective device for protecting the torsion spring is also provided on the inner side of the cover.

[0016] Furthermore, the bottom of the loop interface module is provided with a support block, and the support block is in contact with the hook assembly.

[0017] Furthermore, the width of the support block is set to 1 / 3 to 1 / 2 of the bottom width of the loop interface module.

[0018] The device of this utility model is mainly an improvement on the patent with publication number CN221384594U, and the two have the same working principle. Specifically, in this utility model, the pipeline interface module has a first channel that can be connected to an external device, and the loop interface module has a second channel. When the second channel is connected to the first channel, it forms a disinfection loop. The hook assembly includes a straight section and a guide section. The storage container can be hung on the guide section and slide along it to push the loop interface module to move along the interior of the body. The storage container has a third channel that is connected to its inner cavity. When the third channel is connected to the first channel, it forms a preparation loop.

[0019] The specific working principle of this utility model is as follows: Opening the cover causes the pipe interface module to move upwards, disengaging the first and second channels. Then, the storage container is hung on the guide section. The storage container slides downwards along the guide section under its own weight, ultimately pushing the loop interface module longitudinally until the second and first channels are misaligned and the third channel of the storage container aligns with the first channel. At this point, the cover is closed, causing the pipe interface module to move downwards until the first and third channels are connected, forming a preparation circuit. Connecting the first channel to external equipment allows for the preparation of dialysis concentrate as needed. After preparation, opening the cover and removing the storage container allows the loop interface module to move longitudinally back to its original position. Closing the cover causes the pipe interface module to move downwards until the first and second channels are connected, forming a disinfection circuit. Connecting external equipment allows disinfectant to flow through the disinfection circuit for device disinfection. During the opening and closing process, the cover, via a connecting rod, moves the pipe interface module up and down to connect and seal or disconnect with the loop interface module or storage container.

[0020] The only difference between this invention and existing devices is that this invention makes further improvements in structure, thereby making the device more stable and reliable in use.

[0021] The beneficial effects of this utility model are as follows:

[0022] 1. By setting a limiting component, this utility model can limit the degree of flipping of the cover during the flipping process, thereby preventing the cover from directly colliding with the body and causing structural damage, and extending the service life of the device;

[0023] 2. This utility model uses a slide rail between the main body and the pipeline interface module. On the one hand, it serves as a guide, ensuring that the pipeline interface module moves in a straight line during upward movement, avoiding deviation or shaking, and ensuring the stability of the pipeline interface module's operation. On the other hand, it prevents the pipeline interface module from directly contacting the main body, reducing the frictional resistance during the movement of the pipeline interface module, preventing frictional damage to the equipment, and also saving effort when opening the cover, thus improving the convenience of use.

[0024] 3. The present invention features a flow guide groove at the loop interface module, which can prevent the concentrate from crystallizing and settling at the interface of the loop interface module, and facilitates cleaning of the loop interface module after the device is used, making it highly practical.

[0025] 4. The guide tube and guide groove in this utility model can play a guiding role, preventing the loop interface module from shifting or shaking during movement, and ensuring the stability of the loop interface module operation;

[0026] 5. The snap-fit ​​groove at the bottom of the pipeline interface module and the snap-fit ​​block at the top of the loop interface module in this utility model can cooperate to ensure that the pipeline interface module and the loop interface module are aligned, thereby realizing the smooth closing of the cover and facilitating the use of the device;

[0027] 6. The protective device installed on the cover of this utility model can serve as a hinge support seat and also protect the torsion spring, preventing the torsion spring from being exposed and causing damage and rust, thus extending the service life of the device.

[0028] 7. The support block set at the bottom of the loop interface module in this utility model can support the loop interface module and reduce the frictional resistance between the loop interface module and the hook assembly; it can also scrape the hook assembly through the support block, that is, when the surface of the hook assembly crystallizes, the loop interface module can scrape off the crystals on its surface to ensure the normal use of the device.

[0043] The illustrated embodiments are provided to better illustrate the present invention, but the content of the present invention is not limited to the illustrated embodiments. Therefore, non-essential improvements and adjustments made to the implementation schemes by those skilled in the art based on the above-described content of the present invention still fall within the protection scope of the present invention.

[0044] like Figures 1 to 11 As shown, a dialysis concentrate preparation device includes a body 1, a cover 2, a pipeline interface module 3, and a loop interface module 4. The top of the cover 2 is hinged to the upper end of the body 1. The pipeline interface module 3 is located above the loop interface module 4. Both the pipeline interface module 3 and the loop interface module 4 are movably connected to the body 1, and the pipeline interface module 3 is hinged to the cover 2 via a connecting rod 5. The device also includes a hook assembly 6 for suspending a storage container located below the loop interface module 4. When the hook assembly 6 suspends the storage container, the storage container can push the loop interface module 4 to slide along the interior of the body 1.

[0045] It also includes a limiting member 7 set on the top of the pipeline interface module 3, and a fixing member 8 set on the upper end of the body 1; during the process of the cover 2 flipping upward, the limiting member 7 moves upward to abut against the fixing member 8, thereby restricting the cover 2 from continuing to flip backward and collide with the body 1.

[0046] like Figures 1 to 7As shown, in this utility model, the limiting member 7 consists of two wedge-shaped blocks set on the top of the pipeline interface module 3, with through holes on the two wedge-shaped blocks. The lower end of the connecting rod 5 is located between the two through holes, and the connecting rod 5 and the two wedge-shaped blocks are hinged by a pin. The upper end of the connecting rod 5 is hinged to the cover 2, specifically by a pin hinge. The fixing member 8 consists of two plate-shaped structures fixed to the edge of the cover 2, with through holes on both plate-shaped structures. The upper end of the cover 2 is connected to the fixing member 8 by a hinge rod 20, realizing the hinge connection between the cover 2 and the body 1. In actual design, the fixing member 8 can be two separate plate-shaped structures fixed to the body 1; or the two fixing members 8 can be connected into a whole structure by a connector and then fixed to the body 1, where the connector can play a reinforcing role. This utility model preferably uses a connector to connect the two fixing members 8 into a whole structure. This connection method can fix the fixing members 8 together, which is convenient for installation and makes the structure of the two fixing members 8 after being connected into a whole more stable.

[0047] During the opening of the cover 2, the limiting member 7 moves upward along with the pipeline interface module 3 until it touches the bottom of the fixing member 8. At this point, the cover 2 can no longer be flipped, thus preventing the cover 2 from colliding with the body 1. By setting the limiting member 7, this utility model can limit the degree of flipping of the cover 2 during the flipping process, thereby preventing the cover 2 from directly colliding with the body 1 and causing structural damage.

[0048] like Figure 4 and Figure 5 As shown, this utility model also includes a slide rail 9 disposed between the main body 1 and the pipeline interface module 3. During the flipping process of the cover 2, the pipeline interface module 3 moves vertically on the main body 1 along the slide rail 9.

[0049] The slide rail 9 is a track mounted on the main body 1, specifically one or more tracks. The back of the pipeline interface module 3 has a slider structure that matches the slide rail 9. The slide rail 9 is a common structure in the prior art, such as a rectangular track, a triangular track, a dovetail groove track, or a circular track structure. The specific design can be selected according to the actual situation.

[0050] This utility model uses a slide rail 9 between the main body 1 and the pipeline interface module 3. On the one hand, it serves as a guide, ensuring that the pipeline interface module 3 moves in a straight line during its upward movement, avoiding deviation or shaking, and ensuring the stability of the pipeline interface module 3's operation. On the other hand, it prevents the pipeline interface module 3 from directly contacting the main body 1, reducing the frictional resistance during the movement of the pipeline interface module 3, preventing frictional damage to the equipment, and also saving effort when opening the cover 2.

[0051] like Figure 1 , Figure 6 , Figure 8 , Figure 10 and Figure 11 As shown, in this utility model, the top of the loop interface module 4 is provided with two guide grooves 11 for draining liquid leaking from the pipeline interface module 3. Both guide grooves 11 are inclined, and the end of the guide groove 11 near the middle of the loop interface module 4 is higher than the other end. A water receiving tray 10 is also provided on the body 1 below the lower end of the guide groove 11.

[0052] In existing devices, the loop interface module 4 has four interfaces, each located in a stepped groove. However, due to environmental factors such as temperature and humidity, the interfaces are prone to crystallization and sedimentation of the concentrate, making them difficult to clean. Therefore, this invention improves upon this by creating a guide groove 11 at the top of the loop interface module 4. The guide groove 11 is divided into two sections, both inclined, with a snap-fit ​​block 16 positioned between the two guide grooves 11, as detailed below. Figure 11 As shown. It should be noted that... Figure 11 This diagram merely illustrates the positional relationship between the guide channel 11 and the snap-fit ​​block 11, primarily to show the inclined state of the guide channel 11, and does not represent the actual physical state. The aforementioned structure of this invention allows liquid leaking from the pipeline interface module 3 to flow along the guide channel 11 provided on the loop interface module 4 to the water receiving tray 10, preventing the concentrated liquid from crystallizing and settling at the interface of the loop interface module 4. Furthermore, it facilitates cleaning of the loop interface module 4 after use, making it highly practical.

[0053] like Figure 4 , Figure 8 and Figure 9 As shown, in this utility model, the loop interface module 4 includes a helical spring 12, one end of which is connected to the body 1 and the other end of which is connected to the loop interface module 4. A guide tube 13 is provided on the body 1, and a guide groove 14 matching the guide tube 13 is provided on the loop interface module 4. The guide tube 13 is sleeved on the outside of the helical spring 12, and one end of the guide tube 13 is fixed on the body 1, while the other end is suspended in the guide groove 14. After the discharge container is configured, as the loop interface module 4 slides along the inside of the body 1, the guide tube 13 enters the guide groove 14, and the helical spring 12 is compressed.

[0054] In this invention, the guide tube 13 and guide groove 14 work together to guide the circuit interface module 4, preventing it from shifting or shaking during movement and ensuring its operational stability. After the discharge container is installed, as the circuit interface module 4 slides along the interior of the body 1, the guide tube 13 enters the guide groove 14, compressing the helical spring 12. Therefore, when the storage container is removed, the helical spring 12 returns to its original position, pushing the circuit interface module 4 below the pipeline interface module 3.

[0055] like Figure 1-3and Figure 8-10 As shown, in this utility model, the bottom of the pipeline interface module 3 is provided with a snap-fit ​​groove 15; the top of the loop interface module 4 is provided with a snap-fit ​​block 16 that matches the snap-fit ​​groove 15, and the upper longitudinal section of the snap-fit ​​block 16 is triangular, bullet-shaped or teardrop-shaped; when the cover 2 is in place, the snap-fit ​​block 16 is embedded in the snap-fit ​​groove 15.

[0056] When the device of this utility model is idle or during disinfection (during disinfection, the first channel of the pipeline interface module 3 and the second channel of the loop interface module 4 are connected to form a disinfection loop), the snap-fit ​​block 16 needs to be embedded into the snap-fit ​​groove 15 to ensure that the pipeline interface module 3 and the loop interface module 4 are aligned. Setting the upper longitudinal section of the snap-fit ​​block 16 to a triangular, bullet-shaped, or teardrop-shaped structure can serve as a guide. Even if the pipeline interface module 3 and the loop interface module 4 are not aligned during the closing of the cover 2, the snap-fit ​​block 16 can be easily embedded into the snap-fit ​​groove 15 under the guiding effect of its upper part, thereby aligning the pipeline interface module 3 and the loop interface module 4 and achieving smooth closing of the cover 2. To further ensure smooth docking of the snap-fit ​​block 16 and the snap-fit ​​groove 15, the edges of the snap-fit ​​block 16 in this utility model are all rounded. In a preferred embodiment of this utility model, the upper longitudinal section of the snap-fit ​​block 16 is set to a triangular shape.

[0057] In this invention, the width of the snap-fit ​​groove 15 should be large enough to ensure smooth engagement with the snap-fit ​​block 16 during the closing process of the cover 2. Specifically, the width of the snap-fit ​​groove 15 is 3 / 5 to 3 / 4 of the bottom width of the pipe interface module 3, and the snap-fit ​​block 16 is fitted with the snap-fit ​​groove 15 with a clearance. In a preferred embodiment of this invention, the width of the snap-fit ​​groove 15 is 3 / 4 of the bottom width of the pipe interface module 3.

[0058] like Figure 3 , Figure 6 and Figure 7 As shown, in this utility model, a torsion spring 17 is provided at the connection between the cover 2 and the body 1, and a protective device 18 for protecting the torsion spring 17 is also provided on the inner side of the cover 2.

[0059] The protective device 18 is a box-shaped structure located inside the cover 2. Both the protective device 18 and the cover 2 have receiving grooves 21 for accommodating the fixing member 8, ensuring that the fixing member 8 and the protective device 18 do not affect the normal flipping of the cover 2. The end of the fixing member 8 is embedded in the receiving groove 21, and the hinge rod 20 at the upper end of the cover 2 passes through the fixing member 8 and the protective device 18, thereby hinged the protective device 18 to the fixing member 8. That is, the protective device 18 acts as a hinge support; the protective device 18 is fixed to the cover 2, and the protective device 18 is hinged to the fixing member 8, thus achieving the hinged connection between the cover 2 and the fixing member 8. Since the fixing member 8 is fixed to the body 1, the hinge of the fixing member 8 and the protective device 18 achieves the hinged connection between the cover 2 and the body 1.

[0060] The torsion spring 17 is sleeved on the hinge rod 20 located inside the protective device 18. The torsion spring 17 is placed inside the protective device 18 to prevent the torsion spring 17 from being exposed, which could lead to damage and rust, and thus protects the torsion spring 17.

[0061] In this invention, the bottom of the loop interface module 4 is provided with a support block 19, and the support block 19 contacts the hook assembly 6. In this invention, only the support block 19 of the loop interface module 4 contacts the bottom bearing device; the other parts of the bottom of the loop interface module 4 are suspended in the air, and the support block 19 contacts the straight section 601 of the hook assembly 6. This structure reduces the contact area between the bottom of the loop interface module 4 and the body 1 or the hook assembly 6, thereby reducing the contact area between the bottom of the loop interface module 4 and other parts, reducing the sliding friction resistance between the loop interface module 4 and the hook assembly 6, and facilitating the movement of the loop interface module 4 along the straight section 601 of the hook assembly 6 into the body 1 during the hanging of the storage container.

[0062] To further reduce the frictional resistance between the loop interface module 4 and the hook assembly 6, the edge of the straight segment 601 in this invention is rounded. Furthermore, the width of the support block 19 is set to 1 / 3 to 1 / 2 of the bottom width of the loop interface module 4, and the support block 19 is positioned at the edge of the loop interface module 4 near the cover 2. In a preferred embodiment of this invention, the width of the support block 19 is set to 1 / 2 of the bottom width of the loop interface module 4. By employing the above-mentioned arrangement, while reducing the frictional resistance between the loop interface module 4 and the hook assembly 6, the support block 19 also scrapes against the hook assembly 6. When crystals form on the surface of the hook assembly 6, the loop interface module 4 can scrape off the crystals, ensuring the normal operation of the device.

[0063] This utility model is mainly based on improvements to the above-mentioned structure. In actual design, it also includes O-rings, support blocks, locking blocks, locking rods, locking tongues, hand grips, limit switches, monitoring modules, electrodes, and electronic tags. All of the above structures are existing structures, and their structures and principles are the same as those in the patent with publication number CN221384594U. Those skilled in the art can implement them conventionally.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
