Description

Technical Field

[0001] This utility model belongs to the field of medical auxiliary products technology, specifically relating to a waterproof dressing for intravenous indwelling needles. Background Technology

[0002] An indwelling catheter, also known as a venous cannula, consists of a soft catheter and cannula that can be left in a blood vessel, and a stainless steel puncture guide needle. The use of indwelling catheters can reduce the pain and fear of injections caused by repeated venous punctures in children. Indwelling catheter dressings are essential items, serving to secure the catheter. However, existing dressings are not waterproof, allowing water to easily enter from the sides. This can cause the patient's skin area around the catheter to become hot and sweaty, leading to discomfort or infection at the insertion site. Furthermore, the dressing may open, affecting the fixation effect, comfort, and safety. After an indwelling catheter is inserted, it is generally recommended that patients use plastic wrap to protect the dressing when showering or washing their face to prevent it from getting wet and causing infection. Clothing can also easily snag or squeeze the catheter, causing it to pull and resulting in pain. Utility Model Content

[0024] This specific embodiment is a waterproof dressing for indwelling intravenous needles, and its structural schematic diagram is shown below. Figures 1-6 As shown, it includes: an Ω-shaped waterproof membrane 1, release paper 10, adhesive layer 11, protective film 13, foam support ring 14, and ventilation assembly; the outer surface of the foam support ring 14 is covered with the protective film 13, and the outer surface of the protective film 13 is installed inside the Ω-shaped waterproof membrane 1; the outer surface of the Ω-shaped waterproof membrane 1 is provided with the adhesive layer 11, and the outer surface of the adhesive layer 11 is adhered with the release paper 10; the ventilation assembly includes: an airbag 2, a connecting tube 3, a plug 5, a flap 7, and a ventilation pipe 9; the ventilation pipe 9 is installed through the outer surface of the Ω-shaped waterproof membrane 1, the plug 5 is provided outside the ventilation pipe 9, the flap 7 is fixedly connected to the outer surface of the plug 5, the connecting tube 3 is installed through the outer surface of the Ω-shaped waterproof membrane 1, and the airbag 2 is installed through the outer surface of the connecting tube 3.

[0025] Specifically, by peeling the release paper 10 off the surface of the adhesive layer 11, the indwelling needle is placed in the protective film 13. The adhesive layer 11 is used to attach and fix the Ω-shaped waterproof membrane 1, the protective film 13, and the foam support ring 14 to the patient's skin, so that the indwelling needle is covered by the protective film 13 and the foam support ring 14 inside the Ω-shaped waterproof membrane 1. The indwelling needle is waterproofed by the action of the Ω-shaped waterproof membrane 1. The indwelling needle is located in the space opened by the foam support ring 14, which effectively prevents clothing from snagging on the indwelling needle or squeezing or pulling the indwelling needle, causing pain to the patient and ensuring its safety. In daily use, the plug 5 is pulled out from the ventilation tube 9 by grasping the peeler 7, so that the inside of the Ω-shaped waterproof membrane 1 can be ventilated. The air bag 2 is squeezed repeatedly to inhale and exhale, pushing the air in the Ω-shaped waterproof membrane 1 through the ventilation tube 9 to increase the air flow effect inside the Ω-shaped waterproof membrane 1, keeping the skin at the indwelling needle site dry inside the Ω-shaped waterproof membrane 1, preventing the skin at the indwelling needle site from being stuffy and sweaty, which may cause discomfort or infection of the needle site, and ensuring its comfort and safety.

[0026] Furthermore, easy-tear tabs 6 are fixedly connected to the outer surfaces of both the Ω-shaped waterproof membrane 1 and the release paper 10.

[0027] Specifically, the Ω-shaped waterproof membrane 1 and the release paper 10 are easy to pull and tear.

[0028] Furthermore, the outer surface of the Ω-shaped waterproof membrane 1 is marked with a mark 4, and the Ω-shaped waterproof membrane 1 is light blue overall.

[0029] Specifically, the light blue Ω-shaped waterproof membrane 1 gives patients a refreshing and reassuring feeling, while also making it easy for medical staff and patients to identify. The label 4 helps patients quickly understand the product brand, usage methods, and precautions.

[0030] Furthermore, a silicone pad 12 is fixedly connected to the outer surface of the protective film 13.

[0031] Specifically, the silicone pad 12 fits snugly against the patient's skin, making the patient more comfortable during use.

[0032] Furthermore, a traction belt 8 is fixedly connected to the outer surface of the ventilation pipe 9, and the traction belt 8 is fixedly connected to the plug 5.

[0033] Specifically, this makes it easier to secure the stopper 5, preventing it from falling out and being lost when it is pulled out.

[0034] Furthermore, a protective net 15 is installed inside the ventilation pipe 9.

[0035] Specifically, this prevents external debris from entering the Ω-shaped waterproof membrane 1 and coming into contact with the indwelling needle when the ventilation pipe 9 is opened, thus avoiding contamination.

[0036] This invention relates to a waterproof dressing for indwelling intravenous catheters. The release paper 10 is peeled off from the adhesive layer 11, and the indwelling catheter is placed inside the protective film 13. The adhesive layer 11 is then used to adhere and fix the Ω-shaped waterproof film 1, the protective film 13, and the foam support ring 14 to the patient's skin. The indwelling catheter is thus encased within the Ω-shaped waterproof film 1, the protective film 13, and the foam support ring 14. The Ω-shaped waterproof film 1 provides waterproofing for the indwelling catheter, and the catheter is positioned within the space created by the foam support ring 14, effectively preventing it from snagging on clothing. To ensure the safety of use, the indwelling needle should not be inserted or squeezed to cause pain to the patient. During daily use, grasp the flap 7 and pull the plug 5 out of the ventilation tube 9 to allow air to pass through the Ω-shaped waterproof membrane 1. Repeatedly squeeze the air bag 2 to inhale and exhale, pushing the air out of or inhaled through the ventilation tube 9 to increase the airflow effect inside the Ω-shaped waterproof membrane 1. This ensures that the skin at the indwelling needle site inside the Ω-shaped waterproof membrane 1 remains dry, preventing discomfort or infection of the needle site due to heat and sweating, and ensuring the comfort and safety of use.

[0037] All technical features in this embodiment can be freely combined according to actual needs.
