Description

Technical Field

[0001] The present invention relates to the technical field of intradermal needles, and in particular to a wheat-grain-shaped intradermal needle for preventing cross infection and an acupuncture method thereof. Background Art

[0002] Intradermal needles, also known as "buried needles", are two types of needles made of stainless steel wire: thumbtack-shaped and wheat-grain-shaped. This method is a development of the ancient acupuncture method of retaining needles. Specifically, it is a method of inserting a needle into the skin, fixing it and retaining it for a certain period of time, and utilizing its continuous stimulation to treat diseases. This method can provide continuous stimulation to the acupuncture points, reducing the trouble of repeated acupuncture, and the patient can also press the buried needles by hand to enhance the stimulation. CN206777524U discloses a press needle, which can combine the steel ring and the tape into one by the upper and lower tapes. The tape and the needle will not fall off when the needle is pulled out, and the raised part of the release paper allows the user to easily remove the press from the needle plate by hand. After the needle is inserted, the release paper can be peeled off, which is convenient to use. Currently, during use, the needle handle needs to be directly grasped with tweezers or fingers to insert the needle. After the needle is inserted, it is fixed with tape. During use, hands and objects may come into contact with the needle body and the fixing tape, which can easily cause cross-infection and other problems, and does not meet hospital infection control requirements. In addition, when removing the needle, it is very easy to use excessive force, and the tape and release paper are too tightly attached, leaving no fulcrum, thus tearing the release paper and tape. The tape and needle are not firmly bonded, causing the tape and needle to fall off, which can easily cause the needle to remain in the body and pose a medical safety hazard. Therefore, it is urgent for those skilled in the art to design a new type of intradermal needle. Summary of the Invention

[0003] The problem to be solved by the present invention is that a release paper is in a semi-broken folded structure. Medical staff only need to pinch the release paper with two fingers to fold it in half. Through the oval tape and the thickened release paper at the bottom, combined with the base plate design for placing and removing the needle, the needle body can be effectively protected from damage. During use, the needle body and the sticky surface of the tape are not touched during the needle removal process, which can avoid secondary infection of the needle body; the diameter of the release paper is larger than the width of the base plate, which is convenient for medical staff to pinch and apply force when pulling out the intradermal needle from the long hole of the base plate. The medical staff can pinch the part of the release paper that exceeds the base plate with two fingers to remove the intradermal needle. It is extremely convenient and can effectively prevent excessive force when pulling out or the tape and the release paper are too tightly attached to each other without a fulcrum, thereby preventing the release paper and the tape from being torn. This is a wheat-shaped intradermal needle and its injection method for preventing cross infection.

[0009] Preferably, a single layer of film is provided between the release paper and the base plate.

[0010] Preferably, the base plate is formed by foam injection molding into an integrally formed structure.

[0011] Preferably, the tape is medical 3M tape.

[0012] Preferably, the method for administering the wheat-grain-shaped intradermal needle comprises the following steps:

[0013] Step 1: The medical staff pinches the part of the release paper that extends beyond the base plate with two fingers;

[0014] Step 2: Fold the release paper in half upwards, attaching the first and second release papers parallel to each other, with the needle inside the skin, the release paper, and the tape aligned horizontally.

[0015] Step 3: Pull out the intradermal needle from the long hole on the base plate;

[0016] Step 4: The medical staff pinches the first and second release papers with two fingers and starts to insert the needle;

[0017] Step 5: After inserting the needle, use your other hand to tear off the first release paper and the second release paper in turn to remove the patch;

[0018] Step 6: Apply the lower end of the tape directly to the needle insertion site, and use the upper and lower ends of the tape to protect and fix the needle inside the skin to complete the needle insertion.

[0019] With the above structure, the beneficial effects are as follows:
