Description

Technical Field

[0001] The invention relates to the technical field of nursing tools, in particular to a nursing tool for indwelling venous catheters. Background Art

[0002] When the intravenous catheter is indwelling, pus is easy to appear on the skin around the intravenous catheter, which can easily cause infection of the patient's skin. In order to prevent pus from remaining on the patient's skin surface, medical staff will use tweezers to drive iodine cotton balls to wipe the pus on the patient's skin surface. This pus cleaning method can indeed have a good cleaning effect on the pus on the patient's skin surface, but in actual use, there are still some shortcomings, such as: 1. When pus remains on the surface of the patient's skin, it is easy for the pus to form scabs. In order to facilitate the cleaning of the scabs, medical staff will use iodine cotton balls to moisten the scabs, and then use tweezers with slightly pointed ends to clamp the scabs. This method can indeed have a better cleaning effect on the scabs, but the ends of the tweezers are also easy to pierce the patient's skin surface; 2. Since the ends of the tweezers are provided with sharp corners, when the sharp-cornered tweezers are used to drive the iodine cotton ball to wipe the pus on the patient's skin surface, the cotton on the iodine cotton ball is easily adhered to the tweezers, which makes it inconvenient for medical staff to replace the iodine cotton ball that absorbs the pus; 3. When the tweezers drive the iodine cotton ball to wipe the scab pus, the iodine cotton ball is easy to stick to the scab pus. As the medical staff moves the iodine cotton ball, the iodine cotton ball is also easy to drive the scab pus to pull the patient's skin, which will increase the patient's discomfort.

[0003] For this reason, we propose a nursing tool for indwelling intravenous catheter. Summary of the invention
