Abstract
Description
Technical Field
[0001] The utility model relates to medical consumables, in particular to a set for measuring the area of drug extravasation region and calibrating the position. Background Technique
[0002] Chemotherapy drug extravasation refers to the leakage of drugs into the surrounding tissues and the skin surface outside the venous lumen during the intravenous infusion of chemotherapy drugs, which can cause serious consequences such as tissue inflammation, erosion, and ulcer. If not treated in time, it may lead to tissue necrosis, impaired function, and permanent damage. When chemotherapy drug extravasation occurs, the swelling range should be evaluated, the boundary of extravasation should be confirmed and marked, and the skin color, temperature, sensation, etc. of the extravasation region should be observed, and the symptoms and signs, the location and range of extravasation, etc. should be recorded. However, the contour of the drug extravasation region is irregular, so it is difficult to accurately measure the extravasation area. In addition, when measuring the extravasation position with a flexible ruler, the distance from a certain anatomical position (such as the wrist transverse crease, elbow transverse crease) of the patient's body to the extravasation region is usually used for calibration. However, when measuring the distance, the zero scale of the flexible ruler used clinically is difficult to be fixed at the anatomical position, resulting in inaccurate and unstable measurement. The measurement and recording of the area and position of the drug extravasation region in nursing work lack standardization and accuracy. Content of the Utility Model
[0003] The technical problem to be solved by the utility model is to provide a set for measuring the area of drug extravasation region and calibrating the position, which can quickly and accurately measure the area of the drug extravasation region and calibrate the leakage position based on the chromogenic reaction principle, and provides quantitative data for the standardized dynamic tracking and observation of the leakage situation.
[0004] In order to achieve the above object, the technical solution adopted by the utility model is: a set for measuring the area of drug extravasation region and calibrating the position, including an area ruler and a positioning ruler. The area ruler is used for measuring the area of drug extravasation to the skin surface, and the positioning ruler is used for calibrating the extravasation position; the area ruler is in a thin sheet shape, the area ruler is provided with a chromogenic indicator, a grid is arranged on the surface of the area ruler, the grid includes a plurality of single cells with the same area and arranged without gaps, and adhesive nodes are uniformly arranged along the edge of the area ruler; the positioning ruler is a long flexible ruler, a scale is arranged on the positioning ruler, and adhesive nodes are arranged at one end of the positioning ruler near the zero scale; the surface of the adhesive node is covered with a release paper.
[0005] As a preferred technical solution of the utility model, a marker pen is further included in its structure.
[0006] As a preferred technical solution of the utility model, sub-grids are arranged in the single cell, and the sub-grids include a plurality of small single cells with the same area and arranged without gaps.
[0007] As a preferred technical solution of the utility model, both the single cell and the small single cell are square, and the number of small single cells in each single cell is 4 or 9 or 16.
[0008] As a preferred technical solution of the present utility model, the single cell is square and the small single cell is rectangular.
[0009] As a preferred technical solution of the present utility model, the dividing line of the single cell is a solid line, and the dividing line of the small single cell within the same single cell is a dotted line.
[0010] As a preferred technical solution of the present utility model, the color-developing indicator is an acid-base indicator.

[0012] As a preferred technical solution of the present utility model, the color-developing indicator is impregnated into the area ruler.
[0013] As a preferred technical solution of the present utility model, the area ruler is made of paper or cloth with a white background color.
[0014] The beneficial effects of adopting the above technical solutions are as follows: Based on the color reaction principle, the present utility model quickly and accurately measures the area of the drug extravasation area by counting the number of two-level grids; the middle area of the extravasation area corresponds to the single cells that are completely within the color-developing range. Only the single cells in this area are counted, and there is no need to count the small single cells, so the counting speed is fast. The edge position of the extravasation area corresponds to the single cells that are partially within the color-developing range. The small single cells in this area are counted, which is more accurate than estimating the color-developing ratio of the larger single cells. The glue nodes on the area ruler are used to fix and cover the area ruler on the skin surface of the drug extravasation area, and the glue nodes on the positioning ruler are used to fix the zero scale of the positioning ruler at a certain anatomical position to measure the distance between the extravasation position and the anatomical position. It improves the standardization and accuracy of the measurement of the area and position of the drug extravasation area in nursing work, and provides quantitative data for the standardized dynamic tracking and observation of the leakage situation. Description of the Drawings
[0015] The following further details the present utility model in conjunction with the drawings and specific embodiments.

[0018] The structure of an embodiment of the present utility model includes an area ruler 1 and a positioning ruler 2. The area ruler 1 is used to measure the area of drug extravasation to the skin surface, and the positioning ruler 2 is used to mark the extravasation position. The area ruler 1 is in the shape of a thin sheet, with a color indicator. The surface of the area ruler 1 is provided with a grid 11, and the grid 11 includes a plurality of single cells 12 with the same area and arranged without gaps. Glue nodes 3 are evenly arranged along the edge of the area ruler 1. The positioning ruler 2 is a long strip-shaped flexible ruler, with a scale 21 provided thereon. Glue nodes 3 are arranged at the end near the zero scale of the positioning ruler 2. The surface of the glue node 3 is covered with release paper. When in use, tear off the release paper, and the area ruler 1 and the positioning ruler 2 can be temporarily fixed in the specified area through the glue nodes 3 for area measurement and position marking.
[0019] A sub-grid 13 is arranged in the single cell 12, and the sub-grid 13 includes a plurality of small single cells 14 with the same area and arranged without gaps. The single cell 12 and the small single cell 14 are both square, and there are 9 small single cells 14 in each single cell 12. The structure also includes a marker pen. The marker pen is used for auxiliary counting. The small single cell 14 can improve the measurement accuracy of the edge position of the extravasation area 4.
[0020] The demarcation line of the single cell 12 is a solid line, and the demarcation line of the small single cell 14 in the same single cell 12 is a dotted line. The demarcation lines adopt two different line types to avoid confusing the areas of adjacent single cells 12.
[0021] The color indicator is an acid-base indicator, and the acid-base indicator is impregnated into the area ruler 1. Most chemotherapy drugs are acidic. When the acid-base indicator of the area ruler 1 contacts the drug extravasated to the skin surface, a color change phenomenon occurs. According to this, the range of the extravasation area 4 is corresponding, and then the single cells 12 in the middle of the colored area and the small single cells 14 at the edge are counted respectively, and the area of the extravasation area 4 can be quickly obtained. The counting of the small single cells 14 with a color change range less than 50% is ignored, those exceeding 50% are recorded as 1 small single cell 14, and those about 50% are recorded as 0.5 small single cells 14.
[0022] The area ruler 1 is made of paper or cloth with a white background color.
[0023] In other embodiments, the single cell 12 is square, the small single cell 14 is rectangular, and the small single cells 14 are arranged in a layout of 3 rows × 4 columns, a total of 12, or in a layout of 2 rows × 3 columns, a total of 6, within the single cell 12.
[0024] In other embodiments, the color indicator is evenly coated on the surface of the area ruler 1.
[0025] Before use, the outer surface of the area ruler 1 is covered with a protective film to prevent the color indicator from losing its effectiveness.
[0026] The colors of the single cell 12 and the small single cell 14 in the attached drawings do not represent the actual colors and are intended to facilitate clear component marking.
[0027] The above description is only put forward as a feasible technical solution of the present utility model and does not serve as a single limiting condition for the technical solution itself.
