Description

Technical Field

[0001] This utility model relates to the field of subcutaneous injection auxiliary tools, specifically to a four-quadrant cyclic injection method marking ruler. Background Technology

[0002] Anticoagulation therapy is fundamental to the prevention and treatment of VTE. In addition, it is widely used in the treatment of related diseases in cardiology, orthopedics, obstetrics and gynecology, and nephrology. Subcutaneous injection of anticoagulants can easily lead to subcutaneous bleeding at the injection site, accompanied by local pain, reducing patient medication adherence and affecting patient satisfaction and trust in nursing care. The abdominal wall is the primary subcutaneous injection site, recognized both domestically and internationally as the preferred site—the abdominal region has a thicker subcutaneous tissue layer, reducing the risk of extravasation; it contains fewer nerve fibers, resulting in relatively less pain; the injection area is large, drug absorption is rapid, and it is not affected by movement; it is easily accepted by patients and convenient to perform. Regularly rotating injection sites and avoiding repeated injections at the same site, with an interval of more than 2 cm between injection points, can significantly reduce bleeding and discomfort such as injection site pain caused by excessively high local drug concentrations. Currently, most clinical medical institutions lack auxiliary tools or proper auxiliary tools to help injection personnel determine the interval distance and duration of injection sites, which easily leads to repeated injections at the same site. This results in a higher probability of subcutaneous bleeding during subcutaneous injections in the abdomen for patients receiving anticoagulant therapy. Summary of the Invention

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the defects in the prior art and thus provide a four-quadrant cyclic injection method marking ruler.

[0004] A four-quadrant cyclic injection method marking ruler includes: a positioning disk, a left marking ruler, an upper marking ruler, a right marking ruler, and a lower marking ruler; the left marking ruler, upper marking ruler, right marking ruler, and lower marking ruler are all connected to the positioning disk; wherein, the left marking ruler is located directly to the left of the positioning disk, the upper marking ruler is located directly above the positioning disk, the right marking ruler is located directly to the right of the positioning disk, and the lower marking ruler is located directly below the positioning disk; the positioning disk, left marking ruler, upper marking ruler, right marking ruler, and lower marking ruler divide the two-dimensional plane space in which the four-quadrant cyclic injection method marking ruler is located into four quadrants; the left marking ruler, upper marking ruler, right marking ruler, and lower marking ruler are each marked with a scale.

[0005] Furthermore, an umbilical positioning hole is provided in the very center of the positioning disc.

[0006] Furthermore, the left and right rulers are of equal length and are symmetrical; the upper and lower rulers are of equal length and are symmetrical.

[0007] Furthermore, the lengths of the left and right indicator rulers are greater than the lengths of the top and bottom indicator rulers.

[0008] Furthermore, the scale lengths of both the left and right rulers are 0-10 cm, in millimeters.

[0009] Furthermore, the scale lengths of both the upper and lower rulers are 0-5 cm, in millimeters.

[0010] Furthermore, the upper left corner of the positioning disk is marked with "Ⅰ", indicating that the quadrant divided by the left and upper marking rulers is quadrant I; the upper right corner of the positioning disk is marked with "Ⅱ", indicating that the quadrant divided by the upper and right marking rulers is quadrant II; the lower right corner of the positioning disk is marked with "Ⅲ", indicating that the quadrant divided by the right and lower marking rulers is quadrant III; and the lower left corner of the positioning disk is marked with "Ⅳ", indicating that the quadrant divided by the lower and left marking rulers is quadrant IV.

[0011] Furthermore, the positioning disc is circular with a radius of 2-4 cm, and the diameter of the umbilical positioning hole is 1 cm.

[0012] Furthermore, the ruler on the left is printed with the following instructions: "When injecting once daily: Monday and Friday, inject into Quadrant I; Tuesday and Saturday, inject into Quadrant II; Wednesday and Sunday, inject into Quadrant III; Thursday, inject into Quadrant IV."

[0013] Furthermore, the right-side indicator ruler is printed with "When injecting twice daily: inject in quadrant I on odd-numbered days in the morning, in quadrant II on even-numbered days in the morning, in quadrant III on odd-numbered days in the afternoon, and in quadrant IV on even-numbered days in the afternoon."; the lower indicator ruler is printed with "Injection is prohibited within 2cm of the navel."

[0014] Instructions for use: When injecting, align the longitudinal axis of the ruler parallel to the longitudinal axis of the body, and align the central hole with the navel.

For twice-daily administration: Odd-numbered mornings, inject into Quadrant I; even-numbered mornings, inject into Quadrant II; odd-numbered afternoons, inject into Quadrant III; even-numbered afternoons, inject into Quadrant IV. Do not inject within 2cm of the navel. During injection, use the markings on the ruler to determine the distance between the current injection site and the previous injection site in the same area. Rotate injection sites regularly to avoid repeated injections at the same site; maintain a distance of at least 2cm between injection points.

[0015] The technical solution of this utility model has the following advantages: 1.
