Description

An infusion port butterfly-wing needle with an auto-fillable balloon

technical field

The utility model relates to the technical field of infusion equipment, in particular to an infusion port butterfly-wing needle with an airbag that can be automatically filled.

Background technique

Implantable venous access port (IVAP), also known as implantable central venous catheter system, referred to as infusion port, requires special butterfly wing non-invasive needle (abbreviated butterfly wing needle) for puncture infusion when using the infusion port . Although the existing infusion needles connected to the infusion port are available in different sizes, they still have a certain distance from the skin after insertion, especially in patients with severe weight loss. The long-term pressure of the wings on the skin can easily cause discomfort to the patient and easily cause skin pressure injury. Therefore, after puncture in clinical operations, a dressing should be placed under the wings of the two needles to facilitate film fixation, local skin protection, and patient comfort. In clinical practice, the padding (gauze) dressing is usually cut into a suitable size dressing by manual cutting, and sometimes the size and thickness are not suitable due to incorrect cutting methods and techniques, resulting in easy loosening or slippage, affecting the patient. Infusion; after cutting, the burrs are rough and there are many flocks. When the fixed film of the infusion is torn off, the gauze will stick, so that the film is not easy to tear, which increases the workload of nurses during the operation. Failure to observe aseptic practices may also increase the risk of infection.
