Description

Technical Field

[0001] The utility model relates to a tool for accurate positioning and measurement, belonging to the technical field of medical supplies. Background Art

[0002] At present, when measuring the patient's abdominal circumference clinically, a soft tape measure is usually used to measure through the navel. However, it is impossible to determine a straight line with only one positioning point at the navel. After the tape measure is wrapped around the patient's abdomen, it is difficult for the various parts of the tape measure to be in the same plane, resulting in large measurement errors. In addition, patients with severe conditions will experience abdominal distension and ascites. In order to monitor the progression of the patient's condition, the abdominal circumference usually needs to be measured 1-2 times a day. It is difficult to ensure that the tape measure is in the same measurement position each time, which will further increase the measurement error.

[0003] In order to reduce measurement errors, currently in clinical practice, a line is drawn on the patient's abdominal skin with a pen to make a mark during the first measurement, and a measurement line is determined through the navel and the marked position. The next time you measure, keep the same measurement position as last time through the navel and the marked position to reduce measurement errors. However, when the patient takes a bath or wipes the body, the mark will be wiped off, resulting in no reference point for positioning the next measurement, and it cannot be guaranteed that it is the same position as the last measurement. Alternatively, some patients have problems with their abdominal skin, such as rashes, or the patient does not want to keep marks on the body, so lines cannot be drawn on the patient's abdominal skin for marking. Therefore, the above method cannot effectively solve the problem of improving measurement accuracy. Utility Model Content

[0004] In order to solve the problems existing in the prior art, the utility model provides a tool for accurate positioning and measurement, which can conveniently use the positioning secondary ruler and the measuring main ruler to determine the two body surface reference points to determine the measurement line for reference in each measurement, thereby reducing the errors caused by different measurement personnel or different measurement standards in each measurement.

[0005] The utility model achieves the above-mentioned purpose by adopting the following technical solutions:

[0006] A tool for accurate positioning and measurement, comprising a vertically arranged positioning secondary scale and a measuring main scale, wherein the measuring main scale is provided with a positioning hole, and the positioning secondary scale and the measuring main scale are connected by a sliding mechanism so that the positioning secondary scale can be slidably arranged on the measuring main scale along its length and width directions.

[0007] Optionally, the sliding mechanism includes:

[0008] A sliding groove is provided on the positioning secondary ruler, and the sliding groove penetrates the positioning secondary ruler along the thickness direction of the positioning secondary ruler;

[0009] A sliding sleeve is sleeved on the outside of the main measuring scale, and the sliding sleeve is provided with a sliding cavity for the main measuring scale to pass through;

[0010] A threaded column is threadedly connected to the sliding sleeve, and the threaded column is vertically arranged to the scale surface of the positioning secondary scale and the measuring main scale. The inner end of the threaded column is screwed into the sliding cavity and an anti-slip sheet is arranged at its inner end. The outer end of the threaded column passes through the sliding groove on the positioning secondary scale and a pressure rod is arranged at the outer end of the threaded column.

[0011] Optionally, the scale ranges of the positioning secondary ruler and the measuring main ruler are 0-30 cm and 0-200 cm respectively.

[0012] Optionally, the 0 scale of the main measuring ruler is set at the positioning hole.

[0013] Optionally, the positioning secondary ruler, the measuring main ruler and the sliding sleeve are made of transparent material.

[0014] The beneficial effects of this application include but are not limited to:

[0015] The utility model provides an accurate positioning and measuring tool, which consists of a vertically arranged positioning secondary ruler and a measuring main ruler. The positioning secondary ruler and the measuring main ruler are connected by a sliding mechanism, so that the positioning secondary ruler can be slidably arranged on the measuring main ruler along its length and width directions.

[0016] When applied to abdominal circumference measurement, the specific method for determining the second positioning point other than the navel is: when the main measuring ruler is in a horizontal state passing the navel, adjust the position of the positioning sub-rule so that the lower end point of the positioning sub-rule is located at the patient's anterior superior iliac spine, and record the scale on the positioning sub-rule at the vertical intersection of the positioning sub-rule and the main measuring ruler as the standard for determining the second positioning point for use in the next measurement. During actual measurement, the first positioning point is determined by placing the positioning hole on the main measuring ruler at the navel, and the second positioning point is determined by placing the lower end of the positioning sub-rule at the anterior superior iliac spine. The measurement line can be determined through the two points, and the same measurement line is used for each measurement to achieve accurate positioning and measurement of abdominal circumference measurement, reducing errors caused by different measurement personnel or different measurement standards during each measurement.

[0017] The accurate positioning and measuring tool provided by the utility model can conveniently use the positioning secondary ruler and the measuring main ruler to determine the two body surface reference points to determine the measuring line in actual application for reference each time measurement is used. In addition to being used for abdominal circumference measurement, the measuring tool provided by the utility model can also be used for dimensional measurement in other application scenarios. For example, when measuring the head circumference of a patient with cerebral edema, the patient's eyebrows can be used as the reference point for the positioning secondary ruler; the abdominal circumference and uterine height of a parturient can also be measured, and the leg circumference of a patient with lower limb edema can also be measured.

[0024] In order to clearly illustrate the technical features of the present invention, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0025] It should be noted that many specific details are described in the following description to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0026] like Figure 1-Figure 3 As shown in the figure, the accurate positioning and measuring tool provided by the utility model comprises a vertically arranged positioning secondary ruler 100 and a measuring main ruler 200, a positioning hole 210 is provided on the measuring main ruler 200, and the positioning secondary ruler 100 and the measuring main ruler 200 are connected by a sliding mechanism 300, so that the positioning secondary ruler 100 can be slidably arranged on the measuring main ruler 200 along its length and width directions.

[0027] It can be understood that, like conventional measuring rulers, the extension direction of the scales on the positioning secondary ruler 100 and the measuring main ruler 200 in the present invention is the same as the length direction of the ruler.

[0028] When used for waist circumference measurement, it is necessary to determine a second positioning point other than the navel. The specific steps are: make the main measuring ruler 200 in a horizontal state passing the navel, slide the positioning secondary ruler 100 and the main measuring ruler 200 up and down and left and right relative to each other, so that the lower end point of the positioning secondary ruler 100 is located at the patient's anterior superior iliac spine. Record the scale on the positioning secondary ruler 100 at the vertical intersection of the positioning secondary ruler 100 and the main measuring ruler 200 for easy use in the next measurement.

[0029] Then, the formal measurement is performed while keeping the relative position of the positioning secondary ruler 100 and the measuring main ruler 200 unchanged. The specific steps are: the positioning hole 210 on the measuring main ruler 200 is placed at the navel to determine the first positioning point, and the lower end of the positioning secondary ruler 100 is located at the anterior superior iliac spine to determine the second positioning point. The horizontal measurement line can be determined by the two points. Next, one hand presses the measuring main ruler 200 between the anterior superior iliac spine and the navel, and the other hand pinches the second end of the measuring main ruler 200 from the back of the patient to the front side, appropriately tightens the measuring main ruler 200 to prevent the measuring main ruler 200 from being loose, and reads the scale of the intersection of the measuring main ruler 200 and the navel to measure the patient's abdominal circumference.

[0030] When measuring next time, first adjust the up and down position of the positioning secondary ruler 100 so that it is located at the last recorded scale. Then, place the positioning hole 210 on the measuring main ruler 200 at the navel (first positioning point), and adjust the left and right position of the positioning secondary ruler 100 so that the lower end of the positioning secondary ruler 100 is located at the anterior superior iliac spine (second positioning point). In this way, the same measurement line as the last measurement is determined through the two positioning points, thereby improving the measurement accuracy.

[0031] In actual operation, after the position of the positioning secondary ruler 100 is adjusted, it is necessary to fix the position of the positioning secondary ruler 100 relative to the measuring main ruler 200 to prevent the measurement accuracy from being affected by the position change of the positioning secondary ruler 100. The specific fixing method can be achieved with the assistance of the structure of the sliding mechanism 300. In a preferred embodiment, the sliding mechanism 300 includes:

[0032] A sliding groove 310 is provided on the positioning secondary ruler 100, and the sliding groove 310 penetrates the positioning secondary ruler 100 along the thickness direction of the positioning secondary ruler 100;

[0033] A sliding sleeve 320 is sleeved on the outer side of the measuring main scale 200, and the sliding sleeve 320 is provided with a sliding cavity 321 for the measuring main scale 200 to pass through;

[0034] A threaded column 330 is threadedly connected to the sliding sleeve 320, and the threaded column 330 is vertically arranged to the scale surface of the positioning secondary scale 100 and the measuring main scale 200. The inner end of the threaded column 330 is screwed into the sliding cavity 321, and an anti-slip sheet 331 is arranged at its inner end. The outer end of the threaded column 330 passes through the sliding groove 310 on the positioning secondary scale 100, and a pressure rod 340 is arranged at the outer end of the threaded column 330.

[0035] like Figure 3 As shown in , the sliding sleeve 320 matches the width of the measuring main scale 200, so that the sliding sleeve 320 can slide smoothly along the measuring main scale 200. The threaded column 330 is connected to the sliding sleeve 320, and the threaded column 330 passes through the sliding groove 310 on the positioning secondary scale 100, so when the positioning secondary scale 100 is pinched and moved left and right, the threaded column 330 and the sliding sleeve 320 will be driven to slide along the length direction of the measuring main scale 200. Figure 4 As shown in , when the inner end of the threaded column 330 is screwed into the sliding cavity 321, the positioning secondary scale 100 can be pressed against the sliding sleeve 320 through the pressing rod 340, so that the upper and lower positions of the positioning secondary scale 100 relative to the measuring main scale 200 are fixed. Furthermore, when the inner end of the threaded column 330 is screwed into the sliding cavity 321, the measuring main scale 200 can also be pressed against the cavity wall of the sliding cavity 321 through the inner end of the threaded column 330, thereby fixing the left and right positions of the positioning secondary scale 100 relative to the measuring main scale 200.

[0036] It is understandable that the size of the pressure rod 340 should be larger than the width of the sliding groove 310 to prevent the pressure rod 340 from falling into the sliding groove 310, so as to ensure that the pressure rod 340 can apply pressure to the positioning secondary ruler 100 to prevent the positioning secondary ruler 100 from being separated from the measuring main ruler 200. The anti-slip sheet 331 at the end of the threaded column 330 is used to prevent the threaded column 330 from slipping out of the sliding sleeve 320.

[0037] When in use, the pressure rod 340 on the threaded column 330 is pinched to rotate the threaded column 330, so that the threaded column 330 and the pressure rod 340 rotate forward together, so that the positioning secondary scale 100 can be pressed between the pressure rod 340 and the sliding sleeve 320, and the friction between the two can prevent the positioning secondary scale 100 from moving up and down; at the same time, the main measuring scale 200 can also be pressed between the front end of the threaded column 330 and the cavity wall of the sliding sleeve 320, so that the sliding sleeve 320 and the main measuring scale 200 are connected as a whole, and the positioning secondary scale 100 has been pressed on the sliding sleeve 320, so the positioning secondary scale 100 cannot move up and down or left and right relative to the sliding sleeve 320, thereby fixing the relative position between the positioning secondary scale 100 and the main measuring scale 200.

[0038] Specifically, in order to achieve the state where the positioning secondary scale 100 is pressed against the sliding sleeve 320 by the pressure rod 340 during the process of the pressure rod 340 moving forward with the threaded column 330, it is necessary that, in the direction along the thickness of the ruler, the thickness d1 of the sliding cavity 321 minus the thickness d2 of the measuring main scale 200 ≥ the distance d3 between the relative surfaces of the pressure rod 340 and the sliding sleeve 320 minus the thickness d4 of the positioning secondary scale 100; further, in order to enable the pressure rod 340 to press the positioning secondary scale 100 while also enabling the end of the threaded column 330 to press the measuring main scale 200 against the sliding sleeve 320, d1-d2=d3-d4 should be satisfied.

[0039] Preferably, in order to improve the patient's comfort during measurement, a silicone pad is preferably provided on the side of the sliding sleeve 320 close to the patient's body, and the corners of the sliding sleeve 320 are rounded to avoid scratching the patient's skin.

[0040] In addition to the method of fixing the relative position between the positioning secondary scale 100 and the measuring main scale 200 by using the pressure rod 340 and the threaded rod, the sliding sleeve 320 can also be set to an elastic rubber material, and the threaded rod is replaced by a smooth rod body, so that the sliding sleeve 320 is expanded on the outside of the measuring main scale 200, and the positioning secondary scale 100 is squeezed between the pressure rod 340 and the sliding sleeve 320 by the expansion force of the sliding sleeve 320. In this way, the material characteristics of the sliding sleeve 320 can be used to prevent the positions of the measuring main scale 200, the sliding sleeve 320, the positioning secondary scale 100, and the pressure rod 340 from changing easily, but at the same time, when an external force is applied, the measuring main scale 200 can be allowed to slide left and right relative to the sliding sleeve 320, and the positioning secondary scale 100 can be allowed to slide up and down relative to the sliding sleeve 320.

[0041] The positioning secondary ruler 100 , the measuring main ruler 200 , and the sliding sleeve 320 are made of transparent materials, so that the scale on the measuring main ruler 200 can be clearly observed.

[0042] The size of the pressure rod 340 is as small as possible as the width of the positioning secondary ruler 100 to prevent the scale of the positioning secondary ruler 100 from being worn away due to the rotational friction of the pressure rod 340 .

[0043] In order to facilitate direct reading of the measured value, the 0 scale mark of the measuring main ruler 200 is usually set at the positioning hole 210 .

[0044] When used for measuring abdominal circumference, the scale ranges of the positioning secondary ruler 100 and the measuring main ruler 200 are 0-30 cm and 0-200 cm respectively.

[0045] In the present invention, the material of the positioning secondary ruler 100 is slightly hard plastic, rubber or silicone material, which is easy to bend but not too hard, otherwise it is inconvenient to fit the skin for measurement.

[0046] In actual application, as long as two reference points on the body surface are determined, the measuring tool provided by the utility model can also be used for dimensional measurement in other application scenarios. For example, when measuring the head circumference of a patient with cerebral edema, the patient's eyebrows can be used as reference points for positioning the secondary ruler; the abdominal circumference and uterine height of a parturient can also be measured, and the leg circumference of a patient with lower limb edema can also be measured.
