Description

TECHNICAL FIELD [0002] Surgical RFID gauze and its manufacturing method for preventing overlap

The present invention relates to a surgical RFID gauze for preventing overlap and a manufacturing method thereof. More specifically, it relates to a surgical RFID gauze for preventing overlap, which can prevent an RFID reception failure caused by agglomeration of different gauze with blood, and a manufacturing method thereof.

In surgery, a large amount of gauze is used to wipe off the blood generated in the patient's body. After use, the gauze must be removed from the patient's body, but the gauze is placed in the patient's body and sutured frequently. To prevent such accidents, the gauze sometimes includes an X-ray contrast chamber. It is to check whether there is gauze in the body through X-ray imaging of the patient after surgery. However, in this case, there is a problem in that the gauze present in the body cannot be completely detected because in many cases it cannot be found by X-ray imaging depending on the position of the gauze in the body.

As another method, a person counts the number of gauze before and after surgery to check whether the number is the same. However, there is a lot of room for mistakes when a person counts the number of gauze, and there are many difficulties in counting the number of gauze after surgery because blood coagulates and is often entangled with other gauze.

Confirmation of the number of gauze before and after surgery is also important in other aspects. In general, by comparing the total weight of the gauze before and after surgery, the amount of bleeding of the patient in the corresponding operation is estimated. In this case, it is important to know exactly the number of gauze used for surgery.

1 is a view showing an RFID gauze for surgery according to an embodiment of the present invention.

Referring to FIG. 1 , in one embodiment of the present invention, the surgical RFID gauze 10 may include an RFID tag 100 and an RFID bonding unit 200 .

The surgical RFID gauze 10 may be made of any one or more materials of cloth, cotton, non-woven fabric, polyamide, polyurethane, polyurethane, and crepe tissue.

The RFID tag 100 is provided on one side of the surgical RFID gauze 10 and may have an antenna. The RFID tag 100 is for measuring gauze for surgery and may include an IC chip. The IC chip may recognize the identification information of the surgical gauze.

In one embodiment, the RFID tag 100 is inserted into the inlay of the surgical RFID gauze 10, and the surgical RFID gauze 10 is combined with the surgical RFID gauze 10 around the RFID tag 100. may be joined. Alternatively, the RFID tag 100 may be provided in a form that is accommodated in the RFID gauze 10 for surgery when weaving the RFID gauze 10 for surgery.

The RFID tag 100 may include a substrate having a substantially rectangular or circular shape. The substrate is in the form of a thin film, and has flexibility to respond to the warpage of the gauze. The IC chip may be mounted on the substrate, and may consist of a communication chip for transmitting and receiving RF signals. The IC chip may be disposed on the substrate, and may consist of a communication chip for high-frequency band communication of 10 MHz to 15 MHz. The antenna may be attached to an upper surface or a lower surface of the substrate, and may have a spiral wound pattern in a circumferential direction of the substrate.

The RFID tag 100 may transmit information stored in the RFID tag 100 by a measuring device including an RFID reader, and the measuring device receives the information of the RFID tag 100 and includes one or more surgical RFID gauze 10 ) can be identified to measure the number of copies.

The RFID bonding portion 200 may be a bonded portion of the surgical RFID gauze 10 around the RFID tag 100 . More specifically, the RFID junction 200 may be a surgical RFID gauze 10 portion covering the upper surface of the RFID tag 100 .

The RFID junction 200 may be water-repellent treated so that blood does not cause agglomeration with other gauze. The provision or bonding of the RFID tag 100 to the surgical RFID gauze 10 is to accurately measure the number of surgical RFID gauze 10 before and after surgery through the instrument. A general surgical gauze is made of a material with a high absorption rate of liquids such as blood. For this reason, in the process of use, blood coagulates on the RFID tag 100 part of the surgical gauze, that is, the RFID junction 200 part, and the patient's body part (organ or flesh) sticks to it, so that the measurement of the number of gauze by the instrument is properly performed. There are cases where it is not performed and is omitted. In addition, even if blood or a part of the patient's body does not adhere to the gauze, if the surgical gauze is in close contact with each other and the RFID tag 100 overlaps, omission may occur in the measurement of the measuring instrument.

For this reason, in the present embodiment, water-repellent treatment is applied to the RFID bonding unit 200 to prevent overlapping of the RFID bonding unit 200 and absorption of blood, thereby eliminating the omission of the measuring instrument.

The water-repellent treatment may be performed using any one of fluorine, polyester, and polysilazane.

FIG. 2 is a view showing a state in which the RFID junction part is wet to test an embodiment of the present invention, and FIG. 3 is a view showing a state in which the RFID junction part is left wet to test an embodiment of the present invention.

Hereinafter, in order to help the understanding of the present invention, a preferred embodiment of water-repellent treatment using fluorine or polyester is presented with reference to FIGS. 1 to 3 . However, the following examples are provided only to help the understanding of the present invention, and the present invention is not limited by the following experimental examples.

<Example 1>

In the surgical RFID gauze 10, 2 cm × 2 cm of the RFID junction 200 is cut out and water repellent treatment is performed using fluorine. Measure dry weight. The cut RFID junction 200 is placed on the petri dish 310, wetted with the water 321 using the dropper 320, and then left for 5 minutes. Thereafter, the wet RFID junction 200 is hung on the ring 330 and left on the stand 340 for 5 minutes. After standing, the weight of the RFID junction 200 excluding the ring 330 is measured.

<Example 2>

The experiment was carried out in the same manner as in Example 1, except that the water repellent treatment was changed to polyester.

<Example 3>

The experiment was performed in the same manner as in Example 2, except that the moisture 321 was changed to Malfi.

<Comparative Example 1>

An experiment was conducted in the same manner as in Example 1, except that water repellent treatment was not performed.

<Comparative Example 2>

Experiments were carried out in the same manner as in Example 2, except that no water-repellent treatment was performed.

[Experiment 1] Weight measurement of RFID junction 200

division dry weight (g) Wet weight (g) Example 1 0.520 0.520 Example 2 0.520 0.520 Example 3 0.520 0.520 Comparative Example 1 0.520 0.560 Comparative Example 2 0.520 0.560

In Example 1, Example 2, and Comparative Example 1, the RFID junction 200 was wetted using water. Among them, in Examples 1 and 2, water repellency treatment was applied to the RFID junction part 200, and Comparative Example 1 was not subjected to water repellency treatment. In Example 3 and Comparative Example 2, water was changed to malfi and an experiment was performed. Example 3 was water-repellent treatment, Comparative Example 2 is not water-repellent treatment.

Referring to the experimental results of Table 1, it can be confirmed that Examples 1 to 3 have the same dry weight and wet weight. This can be said to indicate that the RFID junction 200 has been water-repellent, so the effect is proven. In Comparative Examples 1 and 2, it can be confirmed that the wet weight is 0.040 g heavier than the dry weight. This indicates that the RFID bonding unit 200 is not water-repellent, so that 0.040 g of water or malf is contained in the RFID bonding unit 200 . Therefore, in the RFID gauze 10 for surgery according to an embodiment of the present invention, since the RFID junction 200 is water-repellent, it is possible to prevent the absorption of blood and to prevent the RFID junction 200 from overlapping. It can be seen that omissions can be prevented.
