Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and more specifically, to a medical infusion flow regulator. Background Technology

[0002] In clinical practice of medical infusion, precise control of infusion flow rate is directly related to treatment efficacy and patient safety, making infusion flow regulators indispensable medical devices. However, traditional infusion flow regulators often struggle to achieve fine-tuning. For scenarios with extremely high flow rate requirements, such as infusions for infants and young children or the administration of special drugs, they cannot meet the needs of precise treatment, potentially affecting drug efficacy or causing adverse reactions due to flow deviations. This not only affects the accuracy of flow regulation but also increases the operational difficulty and workload for medical staff. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a medical infusion flow regulator.

[0004] To achieve the above objectives, the present invention provides the following technical solution: Medical infusion flow regulator, including top cover, gasket and bottom cover; The bottom surface of the top cover is provided with an annular groove, the depth of which is configured to control the liquid flow rate, and an inlet pipe connected to the annular groove is fixedly connected to the top cover. The gasket is sandwiched between the upper cover and the lower cover, and the top surface of the gasket facing the upper cover is provided with a first sealing ring and a second sealing ring; After the upper cover, gasket and lower cover are assembled, the annular groove and the top surface of the gasket are pressed together, and together they are enclosed by the first sealing ring and the second sealing ring to form an annular flow channel. A flow hole is provided on the gasket located between the first sealing ring and the second sealing ring; the lower cover is fixedly connected to an outlet pipe that corresponds to and communicates with the flow hole.

[0005] Preferably, the first sealing ring and the second sealing ring are concentric annular protrusions.

[0006] Preferably, the gasket has a third sealing ring and a fourth sealing ring on the bottom surface facing the lower cover.

[0007] Preferably, the third and fourth sealing rings are concentric annular protrusions.

[0008] Preferably, the top surface of the lower cover is provided with a positioning groove that is adapted to the third sealing ring and the fourth sealing ring.

[0009] Preferably, the width of the annular groove is 0.19 mm.

[0010] Preferably, the upper cover and the lower cover are connected by threads. By screwing the upper cover, the degree of compression on the gasket can be changed, thereby adjusting the effective flow cross section of the annular flow channel to achieve flow regulation.

[0011] Preferably, the area between the first sealing ring and the second sealing ring corresponds to and fits into the annular groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This utility model consists of an upper cover, a gasket, and a lower cover, with a simple structure and clearly defined functions for each component. The depth of the annular groove on the bottom surface of the upper cover controls the liquid flow rate, and together with the inlet pipe, it ensures stable liquid input. The gasket is sandwiched between the upper and lower covers. After the upper cover, gasket, and lower cover are assembled, the annular groove and the top surface of the gasket are pressed together to form an annular flow channel, ensuring the sealing of the liquid flow path and providing a precise structural basis for flow rate adjustment. The flow hole on the gasket is connected to the outlet pipe of the lower cover, ensuring smooth liquid output. Through the configuration of the annular groove depth and the cooperation of each component, the liquid flow rate can be finely adjusted according to the actual infusion needs, meeting the infusion flow requirements of different patients and different treatment scenarios, thus improving the targeting and effectiveness of treatment. The restriction of the annular flow channel by the first and second sealing rings, as well as the pressing structure after the assembly of each component, effectively prevents liquid leakage, ensuring the safety and hygiene of the infusion process, and reducing the medical risks and resource waste that may be caused by liquid leakage. It demonstrates outstanding benefits in terms of the accuracy of flow regulation and the reliability of sealing, providing a stable, safe and flexible flow control solution for medical infusion processes, and has high clinical application value and promotion significance.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0018] Reference Figures 1-6 As shown.

[0019] The embodiments further illustrate the medical infusion flow regulator proposed in this utility model.

[0020] A medical infusion flow regulator, comprising an upper cover 1, a gasket 2, and a lower cover 3; The bottom surface of the upper cover 1 is provided with an annular groove 4. The depth of the annular groove 4 is configured to control the liquid flow rate. An inlet pipe 10 connected to the annular groove 4 is fixedly connected to the upper cover 1. The gasket 2 is sandwiched between the upper cover 1 and the lower cover 3, and the top surface of the gasket 2 facing the upper cover 1 is provided with a first sealing ring 5 and a second sealing ring 6; After the upper cover 1, gasket 2 and lower cover 3 are assembled, the annular groove 4 is pressed against the top surface of the gasket 2, and together they are enclosed by the first sealing ring 5 and the second sealing ring 6 to form an annular flow channel. A flow hole 11 is provided on the gasket 2 located between the first sealing ring 5 and the second sealing ring 6; the lower cover 3 is fixedly connected to an outlet pipe 9 that corresponds to and communicates with the flow hole 11. The inlet pipe 10 and the outlet pipe 9 are not located in the same vertical position to prevent the inlet pipe 10 from communicating directly with the outlet pipe 9.

[0021] The upper cover 1, as a key component for liquid input and flow regulation, has an annular groove 4 on its bottom surface that is the core structure for controlling flow. Simultaneously, the inlet pipe 10 fixed on the upper cover 1 provides a channel for liquid to enter the regulator. The gasket 2, sandwiched between the upper cover 1 and the lower cover 3, serves as a seal and transition between the flow channels. Its first sealing ring 5 and second sealing ring 6, positioned on the top surface of the upper cover 1, press against the annular groove 4 after assembly. The first sealing ring 5 and the second sealing ring 6 together restrict the annular groove 4, thus forming an annular flow channel, ensuring that the liquid flows only within this channel. The flow hole 11 on the gasket 2, located between the first sealing ring 5 and the second sealing ring 6, is the key channel for liquid to flow from the annular flow channel to the lower cover 3. The outlet pipe 9 fixed on the lower cover 3 corresponds to and communicates with the flow hole 11, used to output the regulated liquid flow rate.

[0022] During operation, the liquid first enters the annular groove 4 of the upper cover 1 through the inlet pipe 10, and then enters the annular flow channel formed by the annular groove 4, the top surface of the gasket 2, and the first sealing ring 5 and the second sealing ring 6. After the flow rate is regulated within the flow channel, the liquid flows through the outflow hole 11 of the gasket 2 and finally flows out from the outlet pipe 9 of the lower cover 3. The flow rate is regulated by changing the depth of the annular groove 4. The change in the depth of the annular groove 4 changes the effective flow cross-section of the annular flow channel. A larger flow cross-section results in a larger flow rate, and a smaller flow cross-section results in a smaller flow rate, thus meeting different infusion flow rate requirements. At the same time, the setting of the first sealing ring 5 and the second sealing ring 6 not only ensures the sealing performance of the annular flow channel and prevents liquid leakage, but also limits the effective range of the annular groove 4, ensuring the accuracy of flow rate regulation.

[0023] The first sealing ring 5 and the second sealing ring 6 are concentric annular protrusions.

[0024] The first sealing ring 5 and the second sealing ring 6 are concentric annular protrusions. When the upper cover 1, gasket 2, and lower cover 3 are assembled, the annular groove 4 on the bottom surface of the upper cover 1 presses against the top surface of the gasket 2, and is simultaneously constrained by the first sealing ring 5 and the second sealing ring 6, together forming an annular flow channel. Liquid enters from the inlet pipe 10, flows through the annular groove 4, enters the annular flow channel, then passes through the flow hole 11 on the gasket 2, and finally flows out from the outlet pipe 9 of the lower cover 3. The flow rate is adjusted by changing the depth of the annular groove 4. The change in depth changes the effective flow cross-section of the annular flow channel, thereby achieving flow control. The concentric annular protrusion structure of the first sealing ring 5 and the second sealing ring 6 not only ensures the sealing of the flow channel but also limits the effective range of the annular groove 4, ensuring precise flow regulation.

[0025] The bottom surface of the gasket 2 facing the lower cover 3 is provided with a third sealing ring 7 and a fourth sealing ring 8.

[0026] The third sealing ring 7 and the fourth sealing ring 8 are concentric annular protrusions.

[0027] The top surface of the lower cover 3 is provided with a positioning groove that is compatible with the third sealing ring 7 and the fourth sealing ring 8.

[0028] The bottom surface of the gasket 2 facing the lower cover 3 is provided with a third sealing ring 7 and a fourth sealing ring 8, which are concentric annular protrusions. The top surface of the lower cover 3 is provided with a positioning groove that matches the third sealing ring 7 and the fourth sealing ring 8. When the gasket 2 is sandwiched between the upper cover 1 and the lower cover 3, the third sealing ring 7 and the fourth sealing ring 8 cooperate with the positioning groove on the top surface of the lower cover 3. On the one hand, this enhances the sealing performance between the gasket 2 and the lower cover 3, preventing liquid leakage from this area; on the other hand, it also positions the gasket 2 to prevent it from shifting during use, thereby ensuring the stability and sealing reliability of the entire flow regulator structure. This ensures that the liquid flows only sequentially through the inlet pipe 10, the annular groove 4, the annular flow channel, the flow hole 11, and the outlet pipe 9, achieving precise flow regulation.

[0029] The width of the annular groove 4 is 0.19 mm.

[0030] The annular groove 4 on the bottom surface of the top cover 1 has a width of 0.19 mm. This annular groove 4, together with the first sealing ring 5 and the second sealing ring 6 on the top surface of the gasket 2, forms an annular flow channel. Its width is one of the key structural parameters for controlling the liquid flow rate. By screwing the top cover 1 to change its pressure on the gasket 2, the effective flow cross-section of the annular flow channel is changed. Combined with the 0.19 mm width design of the annular groove 4 itself, precise adjustment of the infusion flow rate can be achieved.

[0031] The upper cover 1 and the lower cover 3 are connected by threads. By screwing the upper cover 1, the degree of compression on the gasket 2 is changed, thereby adjusting the effective flow cross section of the annular flow channel to achieve flow regulation.

[0032] The upper cover 1 and the lower cover 3 are connected by threads. When in use, the upper cover 1 is screwed on to change the degree of compression of the upper cover 1 onto the gasket 2. This change in compression adjusts the effective flow cross-section of the annular flow channel, thereby regulating the infusion flow rate.

[0033] The area between the first sealing ring 5 and the second sealing ring 6 corresponds to and fits into the annular groove 4.

[0034] In this medical infusion flow regulator, the area between the first sealing ring 5 and the second sealing ring 6 corresponds to and fits into the annular groove 4 on the bottom surface of the upper cover 1. When the three are assembled, this fitting structure, together with the first sealing ring 5 and the second sealing ring 6, forms an annular flow channel, ensuring that the liquid flows only within this channel. At the same time, it provides a precise structural fit basis for changing the effective flow cross-section of the flow channel and achieving flow regulation by adjusting the depth of the annular groove 4.

[0035] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
