Description

Safety IV Connection Kit and Instructions for Use

[0001] The present invention relates to a safety IV catheter connection kit and a method of using the same.

[0002] In general, hospitals administer intravenous fluids or medications to patients who cannot adequately consume essential nutrients orally to maintain / replenish fluids, electrolytes, vitamins, proteins, fats, and calories, to maintain appropriate blood components, or to quickly supply medications in emergency situations.

[0003] In general, a catheter is a medical device that is inserted into a patient's body to administer liquid medication or drain bodily fluids. Along with a cannula, it is a medical device that is commonly used during procedures or invasive processes.

[0004] These catheters may need to remain inserted into the patient's skin while receiving treatment. Various methods are known for securing and maintaining the catheter in the treatment site during the procedure or invasive procedure.

[0005] In order to administer intravenous fluid or medication into a patient's vein through an IV syringe, a catheter having a needle film for intravenous injection is first inserted into the patient's blood vessel, and then an IV set adapter and a supply tube are connected to the body of the catheter.

[0006] Figure 1 is a schematic diagram of a conventional catheter inserted into the human body via an IV syringe. Figure 2 is a schematic diagram of an IV set adapter and a feeding tube connected to the catheter. Figure 3 is a schematic diagram of the feeding tube folded and taped multiple times.

[0007] A catheter fixation method commonly used to fix an inserted catheter is as shown in Fig. 3, in which the catheter is inserted into a part of the body, the catheter and the patient's skin are attached using tape to fix the catheter, and then hemodialysis, drug injection, and discharge of contents are measured.

[0008] When fixing a catheter using tape as described above, there was a problem in that when the catheter was inserted into a patient's body part and the tape and catheter were directly attached to the patient's body, the catheter would move, causing a wound to form at the insertion site where the catheter was inserted, and bacteria would enter through the wound, resulting in secondary infection.

[0009] In addition, when adjusting the fixation site after fixation, the tape is removed, the fixation site is adjusted, and the tape and catheter are directly attached to the patient's body, which causes pain to the patient when adjusting the fixation site and interferes with the patient's resting posture, which causes psychological anxiety in the patient.

[0010] Additionally, there was a problem that skin trouble occurred at the fixed fixation site when the catheter was fixed using tape for a long period of time.

[0011] In addition, conventional fixing tapes (bands) are made of solvents (Toluene, Xylene, Benzene, Aldehyde) that are harmful to the human body, so children and the elderly with sensitive skin often complain of pain when removing them after use. In particular, patients with sensitive skin often experience side effects such as rashes or, in severe cases, oozing.

[0012] Accordingly, the present invention has been devised to solve the above-described conventional problems, and according to an embodiment of the present invention, when used, an IV set in which a catheter, an adapter, and a supply tube are combined can be firmly fixed at once, separation of the catheter and the IV set adapter is prevented to enable a luer lock function, and since the catheter and the IV set adapter are not directly pressed through a band, the catheter hub (hanging protrusion) can be prevented from pressing on the skin (pillow function) when used for a long time, thereby providing a safe IV connection kit.

[0013] And, according to an embodiment of the present invention, the purpose is to provide a safety IV connection kit that is integrally provided with a protruding tip for preventing adapter movement in the inner space of the protective cap cover, thereby preventing separation of the catheter and the IV set adapter while fixing the catheter, and preventing movement of the catheter during use.
