Description

Technical Field

[0001] This utility model relates to the technical field of infusion set components, specifically an infusion set venting device. Background Technology

[0002] An infusion set is a common medical device, mainly used for intravenous infusion therapy. It uses gravity to allow the liquid in the infusion bottle or bag to flow into the patient's vein through the tubing of the infusion set. When the liquid passes through the drip chamber, the liquid level in the drip chamber will drop as the liquid flows out, thus creating a certain pressure difference. Usually, an air vent is installed at the drip chamber of the infusion set.

[0003] The existing infusion set venting device still has the following problems when in use: the venting device is usually set above the drip chamber, and its main body is a three-way connector. Each of the three joints of the three-way connector is fitted with a hose. The upper hose is connected to the infusion structure, the upper other hose is connected to the venting nozzle, and the lower hose is connected to the drip chamber. Usually, the drip chamber is squeezed manually to vent the air through the venting nozzle, which is quite inconvenient. Utility Model Content

[0019] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0020] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] It should be noted that the liquid-repellent and gas-permeable membrane is existing technology, namely expanded polytetrafluoroethylene (ePTFE) membrane. Its PTFE material undergoes special treatment, resulting in a more porous microstructure and forming more microchannels. These channels allow gas molecules to pass freely while creating a strong surface tension barrier against the liquid, i.e., liquid-repellent and gas-permeable. This is common knowledge among those skilled in the art and will not be elaborated upon here.

[0023] Please see Figures 1-4In this embodiment of the present invention, an infusion set venting device includes a dripping mechanism, which comprises a rubber tube 1 and a liquid dispensing mechanism 2. A liquid inlet and venting mechanism 3 is provided at the upper end of the rubber tube 1. The liquid inlet and venting mechanism 3 includes a sealing cover 22 that slides against the top of the rubber tube 1. Two fitting sleeves 23 are concentrically fixedly connected to the outer side of the bottom end of the sealing cover 22. A liquid inlet is provided between the upper and lower side walls at the center of the sealing cover 22, and a liquid inlet conduit 24 is fixedly connected to the bottom end of the sealing cover 22 at the opening of the liquid inlet. Two through holes are symmetrically provided between the upper and lower side walls of the sealing cover 22, and a [missing information - likely a device or component] is fixedly installed in each through hole. The system includes an exhaust pipe 26 with an exhaust nozzle 27 fixedly installed at its upper opening. The exhaust end of the exhaust nozzle 27 is fixedly fitted with a liquid-repellent and breathable membrane. The system features an automatic exhaust structure design. A sealing cover 22 is installed above the drip chamber mechanism, with through holes at both ends. An exhaust pipe 26 is fixedly installed inside the through holes, and an exhaust nozzle 27 is fixedly installed at the top of the exhaust pipe 26. The exhaust nozzle 27 is fixedly installed inside the exhaust nozzle 27, allowing excess gas in the infusion set to be automatically discharged and preventing the infusion liquid from overflowing. This eliminates the need for manual pressing of the drip chamber to exhaust gas, making it more convenient and reducing the workload of nursing staff.

[0024] The liquid dispensing mechanism 2 includes a flow guide seat 31 fixedly connected to the inner wall of the lower opening of the rubber tube 1. A flow guide hole with a larger upper diameter and a smaller lower diameter is opened between the center of the upper and lower side walls of the flow guide seat 31. A liquid dispensing connector 32 is fixedly installed at the bottom of the flow guide seat 31 at the opening of the flow guide hole. The discharge end of the bottom of the dripping bucket is fixedly installed with the flow guide seat 31.

The inlet connector 25 can be used with a hose to connect to the infusion structure, i.e., the infusion bottle or infusion bag, and the liquid inside can fall into the dripping mechanism under gravity.

[0027] The working principle of this utility model is as follows: the infusion structure, i.e., the infusion bottle or infusion bag, can be connected through the inlet connector 25 and the hose. The liquid inside can fall into the dripping mechanism under gravity. The discharge end of the dripping bucket is fixedly installed with a guide seat 31. The guide seat 31 has a guide hole with a larger upper part and a smaller lower part in the middle. The outlet connector 32 is fixedly installed at the opening of the guide hole at the bottom of the guide seat 31.
