Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically to a water treatment device for a safety pre-filled syringe. Background Technology

[0002] Water for injection treatment equipment is used to prepare injectable drug solutions. Water for injection is one of the most widely used in the production of sterile preparations. The quality requirements for water for injection have been strictly stipulated in the pharmacopoeia. In addition to the general testing items for distilled water, such as pH, chloride, sulfate, calcium salt, ammonium salt, carbon dioxide, easily oxidized substances, non-volatile substances and heavy metals, it also needs to pass the pyrogen test.

[0003] Existing water treatment equipment for pre-filled safety rope syringes has several drawbacks. Firstly, the conventional interface between the water bag and syringe allows other devices to connect to it, leading to misconnections and potential leakage or contamination of the treated liquid. Secondly, it lacks a stable limiting mechanism for the syringe during filling, making it susceptible to shaking even with slight movement, potentially causing filling failure. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a safe pre-filled syringe water treatment device, which has the advantages of preventing misconnection and avoiding filling failure, thus solving the problems mentioned in the background technology.

[0005] This utility model provides the following technical solution: a safe pre-filled syringe water treatment device, including a water bag body, an interface provided on the outer side of the water bag body, a connecting port slidably connected to the inner wall of the interface, a slot provided on the outer edge of the interface, a storage groove provided on the outer edge of the connecting port, a spring provided on the inner wall of the storage groove, a locking block fixedly installed on the extension end of the spring, a limit block fixedly installed on the outer edge of the locking block, a square plate fixedly installed on the outer side of the water bag body, a sliding groove provided on the top of the square plate, a rotating rod rotatably connected to the inner wall of the sliding groove, a slider threadedly connected to the outer edge of the rotating rod, a clamping plate fixedly installed on the top of the slider, and a syringe body placed on the concave arc surface of the clamping plate.

[0006] As a preferred technical solution of this utility model: the inner wall of the storage slot is provided with a limiting groove, the limiting block is slidably connected to the limiting groove, and the card block is slidably connected to the card slot and the storage slot.

[0007] As a preferred technical solution of this utility model: the diameter of the slider is adapted to the diameter of the groove, and the slider and the groove are slidably connected.

[0008] As a preferred technical solution of this utility model: the concave arc surface of the clamping plate is fixedly installed with an anti-slip and wear-resistant layer, and the outer edges of the rotating rod are provided with threaded posts at both ends, and the two threaded posts are arranged in opposite directions.

[0009] As a preferred technical solution of this utility model: a rotating hole is provided on the outer side of the square plate, and the rotating rod is slidably connected to the rotating hole.

[0010] As a preferred technical solution of this utility model: the clamping plate is slidably connected to the square plate, and the number of clamping plates is two.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This safe pre-filled syringe water treatment device, through the coordinated use of the interface and connection port, allows for easy docking of the syringe body and water bag body. Simply press the locking block inward to insert the connection port into the inner wall of the interface. As the connection port slides inward on the inner wall of the interface until the locking block and the slot are at the same level, the release of the spring's elastic potential energy causes the locking block to engage with the slot, thus fixing the connection port to the interface. This facilitates stable water injection into the syringe body and prevents contamination or operational failure due to misconnection.

[0013] 2. This safety pre-filled syringe water treatment device, through the combined use of a rotating rod and clamping plates, allows the syringe body to be positioned during the injection process. By rotating the rotating rod, two sliders slide simultaneously outward or inward along the inner wall of the chute. This, in turn, causes the two clamping plates to approach and clamp the syringe body. The clamping plates, with their anti-slip and wear-resistant layers, effectively hold and limit the syringe body during injection, ensuring good stability. The syringe body will only move after filling is complete or when the operator actively unlocks it, thus preventing the syringe body from shaking during filling and causing filling failure.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 A water treatment device for a safety pre-filled syringe includes a water bag body 1. A docking interface 2 is provided on the outer side of the water bag body 1. A connecting port 8 is slidably connected to the inner wall of the docking interface 2. A slot 3 is provided on the outer edge of the docking interface 2. A storage groove 16 is provided on the outer edge of the connecting port 8. A spring 4 is provided on the inner wall of the storage groove 16. A locking block 5 is fixedly installed on the extension end of the spring 4. A limit block 6 is fixedly installed on the outer edge of the locking block 5. A square plate 10 is fixedly installed on the outer side of the water bag body 1. A sliding groove 11 is provided on the top of the square plate 10. A rotating rod 12 is rotatably connected to the inner wall of the sliding groove 11. A slider 13 is threadedly connected to the outer edge of the rotating rod 12. A clamping plate 14 is fixedly installed on the top of the slider 13. A syringe body 9 is placed on the concave arc surface of the clamping plate 14.

[0022] In the above structure, by using the interface 2 and the connecting port 8 together, when it is necessary to connect the syringe body 9 and the water bag body 1, simply press the locking block 5 inward and insert the connecting port 8 into the inner wall of the interface 2. When the connecting port 8 slides inward on the inner wall of the interface 2 until the locking block 5 and the slot 3 are at the same level, the release of the elastic potential energy of the spring 4 will cause the locking block 5 to engage with the slot 3, thereby fixing the connecting port 8 to the interface 2. This facilitates stable water injection into the syringe body 9 and prevents misconnection that could lead to contamination or operational failure.

[0023] In a preferred embodiment: a limiting groove 7 is formed on the inner wall of the storage groove 16, the limiting block 6 is slidably connected to the limiting groove 7, and the locking block 5 is slidably connected to the locking groove 3 and the storage groove 16.

[0024] In the above structure, the sliding connection between the limiting groove 7 and the limiting block 6 allows the limiting groove 7 to limit the limiting block 6, thereby achieving the purpose of limiting the card block 5.

[0025] In a preferred embodiment, the diameter of the slider 13 is adapted to the diameter of the groove 11, and the slider 13 and the groove 11 are slidably connected.

[0026] In the above structure, the slider 13 can limit the movement of the two sliding clamping plates 14.

[0027] In a preferred embodiment: the concave arc surface of the clamping plate 14 is fixedly equipped with an anti-slip and wear-resistant layer 15, and the outer ends of the rotating rod 12 are provided with threaded posts, and the two threaded posts are arranged in opposite directions.

[0028] In the above structure, through the cooperation of the rotating rod 12 and the clamping plate 14, when facing the syringe body 9 during the injection process, the rotating rod 12 can be rotated to drive the two sliders 13 to slide outward or inward simultaneously on the inner wall of the slide groove 11, thereby driving the two clamping plates 14 to approach and clamp the syringe body 9. The two clamping plates 14, through the setting of the anti-slip and wear-resistant layer 15, clamp and limit the syringe body 9 during injection, so that the syringe body 9 can maintain good stability during the injection process. The syringe body 9 will only move when the filling is completed or the operator actively unlocks it, thereby avoiding the problem of the syringe body 9 shaking during the filling process and causing filling failure.

[0029] In a preferred embodiment, a rotating hole is provided on the outer side of the square plate 10, and the rotating rod 12 is slidably connected to the rotating hole.

[0030] In the above structure, the rotating rod 12 and the rotating hole allow the rotating rod 12 to rotate smoothly, thereby driving the two sliders 13 and the clamping plate 14 to slide.

[0031] In a preferred embodiment, the clamping plate 14 is slidably connected to the square plate 10, and there are two clamping plates 14.

[0032] In the above structure, the sliding connection between the clamping plate 14 and the square plate 10 allows the two clamping plates 14 to smoothly move closer or further apart when the rotating rod 12 is rotated.

[0033] Working principle: When this device is needed, firstly, the interface 2 and the connecting port 8 can be used together. Then, when it is necessary to connect the syringe body 9 and the water bag body 1, simply press the locking block 5 inward to insert the connecting port 8 into the inner wall of the interface 2. When the connecting port 8 slides inward on the inner wall of the interface 2 until the locking block 5 and the slot 3 are at the same level, the release of the elastic potential energy of the spring 4 will cause the locking block 5 to engage with the slot 3, thereby fixing the connecting port 8 to the interface 2. This facilitates stable water injection into the syringe body 9 and prevents contamination or operational failure due to misconnection. Secondly, the rotating rod 12 and the clamping plate 14 are used to... When used in conjunction with the syringe body 9 during the injection process, the rotating rod 12 can be rotated to cause the two sliders 13 to slide outward or inward simultaneously on the inner wall of the groove 11. This causes the two clamping plates 14 to move closer to clamp the syringe body 9. The two clamping plates 14, through the setting of the anti-slip and wear-resistant layer 15, clamp and limit the syringe body 9 during injection, thereby ensuring that the syringe body 9 maintains good stability during the injection process. The syringe body 9 will only move when filling is completed or when the operator actively unlocks it, thus avoiding the problem of filling failure caused by shaking of the syringe body 9 during the filling process.
