Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a micro-pump connecting valve. Background Technology

[0002] In clinical practice, the use of micro-infusion pumps to deliver medication requires connecting one end of the pump tubing to a connecting valve, with the other two ends of the valve connected to the infusion set and the patient's end, respectively. However, existing micro-infusion pump connecting valves are prone to clogging due to drug-related factors. For example, drugs like insulin and mannitol are susceptible to crystallization when stored at low temperatures, for extended periods, or mixed with other medications. Furthermore, the inherent instability of the drugs themselves can lead to precipitation; for instance, some traditional Chinese medicine injections, with their complex compositions, may precipitate after prolonged storage. Clogging of existing micro-infusion pump connecting valves is difficult to detect promptly, potentially leading to medical accidents. Therefore, it is necessary to provide a new micro-infusion pump connecting valve to address these technical problems. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a micro-pump connecting valve.

[0004] The micro-pump connecting valve provided by this utility model includes a valve body with a hollow tubular structure. One side of the valve body is fixedly installed with an external threaded inlet pipe for connecting to an infusion set, and the other side of the valve body is connected with a movable internal threaded outlet pipe.

[0005] An overflow port is fixedly installed on the valve body near the internal thread outlet pipe, and a blockage monitoring component is installed on the overflow port. The blockage monitoring component includes a mounting cylinder, which is fixedly installed on the overflow port, and a warning light is fixedly installed on the top of the mounting cylinder. A trigger switch for activating the warning light and a trigger element for activating the trigger switch are installed inside the mounting cylinder.

[0006] Preferably, the trigger switch is fixedly installed on the inner top wall of the mounting cylinder, and the trigger switch is electrically connected to the warning light.

[0007] Preferably, the trigger includes a coaxial variable diameter column, which is slidably installed inside the mounting cylinder, and the diameter of the upper column of the coaxial variable diameter column is smaller than the diameter of the lower column. The coaxial variable diameter column is elastically connected to the inner top wall of the mounting cylinder, and a connecting rod is fixedly installed on the upper surface of the coaxial variable diameter column, and a pressing column is fixedly installed on the top of the connecting rod.

[0008] Preferably, a compressed spring is fixedly installed on the coaxial variable diameter column, and the other end of the spring is fixedly connected to the inner top wall of the mounting cylinder. The coaxial variable diameter column seals the overflow port under the action of the spring force.

[0009] Preferably, a central connecting pipe is fixedly installed on the top of the valve body, and multiple inclined threaded one-way connection ports are fixedly installed on the central connecting pipe. A one-way valve is installed in each threaded one-way connection port, and a threaded connecting pipe is installed on the threaded one-way connection port.

[0010] Preferably, a funnel-shaped check valve is installed on the surface of the valve body.

[0011] Preferably, a movable connecting plate is provided between the valve body and the internally threaded outlet pipe.

[0012] Compared with related technologies, the micro-pump connecting valve provided by this utility model has the following beneficial effects:

[0013] When the internal thread outlet pipe of the valve body is blocked due to crystallization or precipitation of the drug, some of the drug flows into the mounting cylinder through the overflow port. At this time, the drug pushes the coaxial variable diameter column to slide up along the mounting cylinder, thereby further compressing the spring. As the coaxial variable diameter column slides up, the pressing column can press the trigger switch to make the warning light light up. Therefore, the staff can quickly know that there is a blockage inside the micro-pump connecting valve so that the valve body can be maintained in time. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0019] Please see Figures 1 to 3 This utility model provides a micro-pump connecting valve, which includes a valve body 1 and a plugging monitoring component 5.

[0020] In the embodiments of this utility model, please refer to Figures 1 to 3The valve body 1 is a hollow tubular structure, and an external threaded inlet pipe 11 for connecting to the infusion set is fixedly installed on one side of the valve body 1, while an internal threaded outlet pipe 12 is movably connected to the other side of the valve body 1. Specifically, a movable connecting plate 121 is provided between the valve body 1 and the internal threaded outlet pipe 12.

[0021] The valve body 1 has a central connecting pipe 2 that is connected to each other fixedly installed on its top. The central connecting pipe 2 has a plurality of inclined threaded one-way connection ports 21 fixedly installed on it. Each threaded one-way connection port 21 is equipped with a one-way valve and a threaded connecting pipe 4 is installed on the threaded one-way connection port 21. The surface of the valve body 1 is equipped with a funnel-shaped check valve 3.

[0022] It should be noted that: when using the infusion set, the external threaded inlet pipe 11 of the micro-infusion pump connecting valve is threadedly connected, and the internal threaded outlet pipe 12 of the micro-infusion pump connecting valve is connected to the patient end to form an infusion passage. When using the micro-infusion pump to pump in the medication, the two ends of the micro-infusion pump tube are connected to the connecting pipe 4 and the medication respectively. The connecting pipe 4 is threadedly fixed to the threaded one-way connection port 21 on the central connecting pipe 2. The central connecting pipe 2 is connected to the valve body 1. Therefore, the medication is pumped into the connecting pipe 4 through the micro-infusion pump tube, into the valve body 1 through the central connecting pipe 2, and then injected into the patient's body to achieve a therapeutic effect.

[0023] Since the central connecting tube 2 is equipped with multiple oblique threaded one-way connection ports 21, multiple connecting tubes 4 can be used to connect multiple drugs to treat patients. This eliminates the need to use multiple connecting valves to meet the needs of simultaneous infusion of multiple drugs, avoiding the increased risk of infection caused by using multiple traditional micro-infusion pump connecting valves.

[0024] Furthermore, when the connecting pipe 4 is not needed, it can be placed at the lower part of the funnel-shaped stop valve 3 to stop the flow and prevent liquid backflow or leakage. At the same time, when the connecting pipe 4 is placed at the upper part of the funnel-shaped stop valve 3, it serves to fix the flow.

[0025] In the embodiments of this utility model, please refer to Figures 1 to 3 An overflow port 13 is fixedly installed on the valve body 1 near the internal thread outlet pipe 12, and a monitoring component 5 is installed on the overflow port 13. The monitoring component 5 includes a mounting cylinder 51, which is fixedly installed on the overflow port 13. A warning light 52 is fixedly installed on the top of the mounting cylinder 51. A trigger switch 53 for activating the warning light 52 and a trigger element 54 for opening the trigger switch 53 are installed inside the mounting cylinder 51. The trigger switch 53 is fixedly installed on the inner top wall of the mounting cylinder 51 and is electrically connected to the warning light 52.

[0026] The trigger 54 includes a coaxial variable diameter column 541, which is slidably installed inside the mounting cylinder 51. The upper diameter of the coaxial variable diameter column 541 is smaller than the lower diameter. The coaxial variable diameter column 541 is elastically connected to the inner top wall of the mounting cylinder 51. Specifically, a compressed spring 544 is fixedly installed on the coaxial variable diameter column 541, and the other end of the spring 544 is fixedly connected to the inner top wall of the mounting cylinder 51. The coaxial variable diameter column 541 seals the overflow port 13 under the elastic force of the spring 544. A connecting rod 542 is fixedly installed on the upper cylindrical surface of the coaxial variable diameter column 541, and a pressing column 543 is fixedly installed on the top of the connecting rod 542.

[0027] It should be noted that when the internal thread outlet pipe 12 on valve body 1 is blocked due to drug crystallization (such as insulin, mannitol, etc., which may crystallize in the connecting valve if not stored and used as required, leading to blockage) or precipitation (such as cephalosporin antibiotics mixed with calcium-containing drugs may generate insoluble substances, blocking the connecting valve), some drugs flow into the mounting cylinder 51 through the overflow port 13. At this time, the drugs push the coaxial reducing column 541 to slide up along the mounting cylinder 51, thereby further compressing the spring 544. As the coaxial reducing column 541 slides up, the pressing column 543 can press the trigger switch 53 to make the warning light 52 light up. Therefore, the staff can quickly know that there is a blockage inside the micro-pump connecting valve so that the valve body can be maintained in time.

[0028] The working principle of the micro-pump connecting valve provided by this utility model is as follows:

[0029] In use, the infusion set is threaded into the external threaded inlet pipe 11 of the micro-infusion pump connecting valve, and the internal threaded outlet pipe 12 of the micro-infusion pump connecting valve is connected to the patient end to form an infusion pathway. When using the micro-infusion pump to pump in medication, both ends of the micro-infusion pump tube are connected to the connecting pipe 4 and the medication, respectively. The connecting pipe 4 is threaded and fixedly connected to the threaded one-way connection port 21 on the central connecting pipe 2. The central connecting pipe 2 is connected to the valve body 1. Therefore, the medication is pumped into the connecting pipe 4 through the micro-infusion pump tube, into the valve body 1 through the central connecting pipe 2, and then injected into the patient's body to achieve a therapeutic effect. Since the central connecting pipe 2 is provided with multiple oblique threaded one-way connection ports 21, multiple connecting pipes 4 can be connected to multiple medications to treat the patient. The need for simultaneous infusion of multiple medications can be met without the need for multiple connecting valves, avoiding the increased risk of infection caused by using multiple traditional micro-infusion pump connecting valves.

[0030] When the internal threaded outlet pipe 12 on valve body 1 is blocked due to drug crystallization (such as insulin, mannitol, etc., which may crystallize in the connecting valve if not stored and used as required, causing blockage) or precipitation (such as cephalosporin antibiotics mixed with calcium-containing drugs may generate insoluble substances that block the connecting valve), some drugs flow into the mounting cylinder 51 through the overflow port 13. At this time, the drugs push the coaxial reducing column 541 to slide up along the mounting cylinder 51, thereby further compressing the spring 544. As the coaxial reducing column 541 slides up, the pressing column 543 can press the trigger switch 53 to make the warning light 52 light up. Therefore, the staff can quickly know that there is a blockage inside the micro-pump connecting valve so that the valve body can be maintained in time.

[0031] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
