Description

Technical Field

[0001] The utility model relates to the medical field, in particular to an adjustable parallel abdominal circumference ruler. Background Art

[0002] For patients whose abdominal circumference increases due to pregnancy, excessive ascites, obesity, childbirth, etc., regular abdominal circumference checks are an important reference indicator of treatment effectiveness. Due to individual differences and other factors, the degree of abdominal circumference increase will vary.

[0003] Typically, medical staff measure the abdomen by wrapping a tape measure around it. The measured value is then calculated based on the reading. However, the actual placement of the tape measure around the abdomen is manually controlled, which can lead to deviations in the actual abdominal circumference data.

[0004] Therefore, a special measuring ruler that can measure abdominal girth more accurately is needed. Utility Model Content

[0005] The purpose of the utility model is to provide an adjustable parallel abdominal circumference ruler. Through the connection structure and the adjustment structure, the measuring ruler and the positioning ruler are placed in a parallel state to each other, so as to achieve the purpose of measuring the abdominal position parallel to the circle where the pubic symphysis and coccyx are located. In combination with the reference piece corresponding to the belly button, the measured abdominal circumference is more accurate and reliable.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An adjustable parallel abdominal circumference ruler includes a measuring ruler, a positioning assembly, and a connecting structure. The measuring ruler is made of a flexible material, includes a head end and a tail end, and the head end is provided with a reference piece corresponding to the navel. The measuring ruler can surround the abdomen, and the tail end is automatically locked with the head end through the connecting structure. The positioning assembly includes a positioning ruler, a connecting piece, and an adjustment structure. The positioning ruler is arranged parallel to the measuring ruler through the connecting piece. The positioning ruler can surround the pubic symphysis and coccyx for a week to be fixed, and the length of the connecting piece can be changed by adjusting the structure.

[0008] Compared with the existing technology, the adjustable parallel abdominal circumference ruler using the above technical solution has the following beneficial effects:

[0009] The adjustable parallel abdominal circumference ruler of the present invention utilizes a connecting structure to temporarily fix the two ends of the measuring ruler. By docking the connecting parts and adjusting the adjustment structure, the measuring ruler and the positioning ruler are placed in a parallel state. When the positioning ruler is fixed to the position of the pubic symphysis and coccyx for a week, combined with the cooperation of the reference part and the navel, the measuring ruler can be fixed in an accurate position, thereby determining the actual abdominal circumference data.

[0010] Preferably, the adjustment structure includes a positioning piece, a positioning slot, and a clamping block. The connecting piece includes a first piece and a second piece. The first piece is perpendicular to and connected to the measuring ruler, and the second piece is perpendicular to and connected to the positioning ruler. The positioning piece is connected to the clamping block via a flexible connection portion, and the end of the clamping block away from the positioning piece is connected to the second piece. There are multiple positioning slots, and the multiple positioning slots are evenly spaced along the length direction of the first piece. The positioning slots are set through the first piece. The positioning piece can be driven by the clamping block to pass through the positioning slot. The flexible connection portion is used to change the relative position of the limiting piece and the clamping block, so that the limiting piece can be passed through the positioning slot and locked, thereby achieving the purpose of temporarily locking the first and second pieces, and facilitating subsequent disassembly and adjustment.

[0011] Preferably, the surfaces of the measuring ruler and the positioning ruler are both provided with scale markings, and the positioning ruler is provided with a positioning piece corresponding to the pubic symphysis. During use, the measuring ruler can be adapted to patients of different body shapes, and the positioning piece can be used to place the positioning ruler in the standard position required for measurement, thereby increasing the accuracy of abdominal circumference measurement.

[0012] Preferably, the positioning slot is obliquely disposed through the first plate, with the two notches of the positioning slot being divided into an insertion end and an extension end, with the extension end being located on the side of the second scale body that is coplanar with the scale markings. With this appropriately tilted positioning slot structure, subsequent adjustments require only a small rotation of the stopper to remove the positioning piece from its slot, simplifying the operation and reducing the difficulty.

[0013] Preferably, the connecting member and the adjustment structure are provided in at least two groups. The multiple groups of connecting members can increase the stability of the connection state and make the measuring ruler and the positioning ruler more accurately parallel, thereby increasing the accuracy of the final waist circumference data.

[0014] Preferably, the reference piece is a perforated structure provided at the head end. The unobstructed perforated structure is used to perfectly fit the special structure of the belly button, and the combination of the two can increase the accuracy of the position of the measuring ruler during use.

[0015] Preferably, the connection structure includes a buckle, multiple stoppers, a docking strip, and an unlocking assembly. The buckle is provided at the leading end of the measuring ruler, and the docking strip is provided at the trailing end of the measuring ruler. The multiple stoppers are evenly spaced along the length of the docking strip and are made of an elastic material. When the measuring ruler is laid flat, the side of the stoppers facing away from the buckle is an inclined surface. The unlocking assembly is provided at the buckle to release the buckle from blocking the stoppers. Utilizing the elastic material's properties of compression and natural expansion, as well as the guiding effect of the inclined surface, the stoppers can be retracted and smoothly passed through the buckle when the docking strip is inserted into the buckle, and the stoppers can then naturally expand to achieve the purpose of locking in place.

[0016] Preferably, the unlocking assembly includes a rotating shaft and a scroll spring, and the buckle includes a base and a movable block. The movable block is connected to the base via the rotating shaft, and the two ends of the scroll spring are respectively connected to the rotating shaft and the base, and the rotating shaft is located in the middle of the base. After the limit block passes through the base, the movable block limits the reverse displacement of the limit block. Utilizing the reset effect of the scroll spring and the special position of the rotating shaft, when the limit block passes through the buckle, it can be ensured that the previously passed limit block remains in a locked state, and the subsequent limit block can continue to pass through, so that the measuring ruler can still be used for the purpose of locking connection when it is suitable for people with different waist circumferences.

[0017] Preferably, a connection structure and an unlocking assembly are provided between the two ends of the positioning ruler. By locking the ends of the positioning ruler, the accuracy of the parallel state of the measuring ruler and the positioning ruler is further increased, providing a stable connection guarantee for the above-mentioned parallel measurement operation.

[0029] Among them, the adjustment structure includes a positioning piece 21, a positioning groove 22 and a clamping block 23, the connecting member includes a first sheet 5 and a second sheet 6, the first sheet 5 is perpendicular and connected to the measuring ruler 1, the second sheet 6 is perpendicular and connected to the positioning ruler 20, the positioning piece 21 is connected to the clamping block 23 through a flexible connection part 24, and the end of the clamping block 23 away from the positioning piece 21 is connected to the second sheet 6, a plurality of positioning grooves 22 are provided, and the plurality of positioning grooves 22 are evenly spaced along the length direction of the first sheet 5, and the positioning grooves 22 are arranged through the first sheet 5, and the positioning piece 21 can be driven by the clamping block 23 to pass through the positioning groove 22.

[0030] The surfaces of the measuring ruler 1 and the positioning ruler 20 are both provided with scale marks 7, and in order to facilitate placing the positioning ruler 20 in an accurate position, the positioning ruler 20 is provided with a positioning piece 9 corresponding to the pubic symphysis. In this embodiment, the positioning piece 9 also adopts a perforated structure.

[0031] In order to facilitate the subsequent separation of the first piece 5 and the second piece 6, a positioning groove 22 is obliquely provided through the first piece 5, and the two notches of the positioning groove 22 are divided into an insertion end 25 and an extension end 26, and the extension end 26 is located on the side of the second ruler body and the scale mark 7 on the same horizontal plane.

[0032] At the same time, in order to increase the stability and accuracy during use, at least two groups of connecting parts and adjustment structures are provided. In this embodiment, one group of connecting parts is placed at the coccyx during use.

[0033] The connecting structure 3 includes a buckle 30, a plurality of limit blocks 31, a docking strip 32 and an unlocking assembly 8. The buckle 30 is provided at the head end 10 of the measuring ruler 1, and the docking strip 32 is provided at the tail end 11 of the measuring ruler 1. The plurality of limit blocks 31 are evenly spaced along the length direction of the docking strip 32, and the limit blocks 31 are made of elastic material. In this embodiment, the positioning ruler 20 is made of the same material as the measuring ruler 1.

[0034] When the measuring ruler 1 is laid flat, the side of the limit block 31 away from the buckle 30 is an inclined surface, and the unlocking component 8 is provided at the buckle 30 to release the blocking of the limit block 31 by the buckle 30 .

After the limit block 31 passes through the base 33, the movable block 34 limits the reverse displacement of the limit block 31.

[0036] In addition, in order to further increase the accuracy during use, the end of the positioning ruler 20 is also fixed in this embodiment, and a connecting structure 3 and an unlocking component 8 are provided between the two ends of the positioning ruler 20.

[0037] The following is how this embodiment is used:

[0038] To facilitate understanding, this application will first describe the use of the connecting structure 3 and unlocking assembly 8. Insert the docking strip 32 of the tail end 11 into the retaining ring 30. Guided by the inclined surface of the stopper 31 and the elasticity of the elastic material, the stopper 31, after extending and retracting through the movable block 34, smoothly passes through the retaining ring 30, temporarily locking the ends of the measuring ruler 1 and the positioning ruler 20.

When the movable block 34 is released, the scroll spring 81 automatically resets the movable block 34 for subsequent use.

[0039] First, connect the measuring ruler 1 and the positioning ruler 20 to form a parallel state, hold the second sheet 6, and insert the positioning piece 21 and the flexible connecting part 24 from the insertion end 25 of the positioning groove 22 through the clamping block 23, and pass them out from the protruding end 26. Adjust the angle of the positioning piece 21 appropriately so that the positioning piece 21 is clamped on the side of the protruding end 26 of the positioning groove 22, thereby realizing the connection between the first sheet 5 and the second sheet 6.

[0040] Based on the location of the pubic symphysis and coccyx, the positioning member 9 is aligned with the pubic symphysis. The positioning ruler 20 is then looped around the pubic symphysis and coccyx, with one of the second pieces 6 positioned at the coccyx. The positioning ruler 20 is then temporarily connected and locked at both ends. The measuring ruler 1 is then held with the perforated reference member 4 aligned with the navel. The connecting structure 3 described above is then used to temporarily lock the leading end 10 and the trailing end 11 of the measuring ruler 1.

[0041] During this process, the direction of the positioning piece 21 can be changed through the flexible connection part 24, and the positioning piece 21 can be smoothly withdrawn from the positioning slot 22. According to the condition of the abdomen 0, the positioning piece 21 is adjusted to be inserted into the positioning slot 22 at a specific position, and the distance between the measuring ruler 1 and the positioning ruler 20 is adjusted. At the same time, the measuring ruler 1 and the positioning ruler 20 are kept in a parallel state. Finally, the scale mark 7 is read to determine the actual abdominal circumference data, and the circumference data of the hips can be measured.

[0042] The above is a preferred embodiment of the present invention. Those skilled in the art may make several modifications and improvements without departing from the principles of the present invention, and these modifications and improvements should also be considered as within the scope of protection of the present invention.
