Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a shape-adjustable 360° visible flexible measuring tape. Background Technology
[0002] Clinically, it is necessary to measure the length of indwelling catheters (such as urinary catheters, drainage tubes, or central venous catheters).
[0003] During use, indwelling catheters can be bent into various irregular shapes (such as wavy or knotted shapes) due to various external factors (such as external pressure, pulling during patient insertion, and different methods of securing the catheter by medical staff). When using existing flat measuring tapes for measurement, the graduation lines are only set on one side of the tape's surface. This single-sided graduation setting requires medical staff to observe from a specific angle.
[0004] Therefore, when using it, not only is it necessary to stand the ruler upright so that the side with the scale is visible to medical staff, but it is also necessary to adjust the flat measuring tape to the same shape as the indwelling tube. This makes the operation difficult, and the measurement accuracy will decrease due to the above two operations.
[0005] Regarding the aforementioned technologies, existing measuring tools suffer from low accuracy in measuring the length of curved indwelling tubes and inconvenient readings. Utility Model Content
[0006] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a shapeable 360° visible flexible tape measure, which aims to solve the problems of low accuracy and inconvenient reading of the length of curved indwelling tubes by existing measuring tools.
[0007] The present application provides a shape-adjustable 360° flexible measuring tape, which adopts the following technical solution: A shape-adjustable 360° flexible measuring tape, comprising:
[0008] A malleable measuring tape body, wherein the cross-section of the malleable measuring tape body is circular;
[0009] The scale lines are provided in multiple ways. All scale lines are arranged along the axial direction of the plastic measuring tape body and are spaced apart around the circumference of the plastic measuring tape body.
[0010] Optionally, the malleable measuring tape body includes a protective layer and a malleable measuring core, the protective layer wrapping around the outer periphery of the malleable measuring core, and the scale lines being disposed on the protective layer.
[0011] Optionally, the scale lines include a first scale line and a second scale line;
[0012] Multiple first scale lines are provided, and the multiple first scale lines are all arranged on the protective layer along the axial direction of the protective layer, and the multiple first scale lines are arranged at intervals around the circumference of the protective layer.
[0013] The second scale line is provided in multiple ways, and the multiple second scale lines are all arranged on the protective layer along the axial direction of the protective layer, and the multiple second scale lines are arranged at intervals around the circumference of the protective layer;
[0014] The first scale line and the second scale line are respectively located at both ends of the plastic measuring tape body, and extend from both ends in opposite directions.
[0015] Optionally, the first scale line includes a first zero scale unit and a plurality of first digital scale units. The first zero scale unit is disposed at one end of the protective layer, and the plurality of first digital scale units are disposed at intervals along the axial direction of the protective layer. Each first digital scale unit is used to indicate the distance between its position and the first zero scale unit.
[0016] The second scale line includes a second zero scale unit and a plurality of second digital scale units. The second zero scale unit is disposed at the other end of the protective layer, and the plurality of second digital scale units are disposed at intervals along the axial direction of the protective layer. Each second digital scale unit is used to indicate the distance between its position and the second zero scale unit.
[0017] Optionally, multiple first digital scale units are spaced apart around their circumference.
[0018] Optionally, multiple second digital scale units are spaced apart around their circumferential positions.
[0019] Optionally, the colors of the plurality of first digital scale units arranged at axial intervals along the protective layer are alternated.
[0020] Optionally, the colors of the plurality of second digital scale units, which are spaced axially along the protective layer, are alternately set.
[0021] Optionally, the first digital scale unit includes a first coarse digital scale and a first subdivided digital scale. The first coarse digital scale is spaced apart along the axial direction of the protective layer, and the first subdivided digital scale is disposed between two adjacent first coarse digital scales.
[0022] Optionally, the second digital scale unit includes a second coarse digital scale and a second fine digital scale. The second coarse digital scale is arranged at intervals along the axial direction of the protective layer, and the second fine digital scale is arranged between two adjacent second coarse digital scales.
[0023] Compared with the prior art, the embodiments of this utility model have the following advantages:
[0024] When using a shapeable 360° visible flexible measuring tape to measure the length of a bent indwelling tube, the flexible body of the measuring tape can be bent and kept in the same state as the indwelling tube for matching. Then, you only need to read the degree of the corresponding scale line at the end of the indwelling tube to determine the length of the indwelling tube.
[0025] Because the cross-section of the malleable measuring tape is circular and it has multiple graduation lines that are spaced apart around the circumference of the measuring tape, the graduation lines are visible 360° around the outer circumference of the measuring tape. Therefore, no matter what shape the measuring tape is bent into, medical staff can easily read the corresponding degree from the measuring tape, which solves the problem that existing measuring tools have low accuracy in measuring the length of bent indwelling tubes and are inconvenient to read.

[0032] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0033] The present application will be further described in detail below with reference to the accompanying drawings.
[0034] This application discloses a shapeable 360° visible flexible measuring tape.
[0035] like Figure 1 As shown, a shapeable 360° visible flexible measuring tape includes a malleable measuring tape body 1 and scale lines 2. The cross-section of the malleable measuring tape body 1 is circular; multiple scale lines 2 are provided, all of which are arranged along the axial direction of the malleable measuring tape body 1, and the multiple scale lines 2 are spaced apart around the circumference of the malleable measuring tape body 1.
[0036] Specifically, the body 1 of the plastic measuring tape is a flexible rope, and the cross-section of the flexible rope is circular.
[0037] The scale line 2 is set with multiple scale lines 2, which are arranged at intervals around the outer circumference of the plastic measuring tape body 1 to ensure that medical staff have at least one scale line 2 for observation from any angle. In this way, even if the plastic measuring tape body 1 is bent from any angle, it will not affect the medical staff's reading.
[0038] When using a shapeable 360° visible flexible measuring tape to measure the length of a bent indwelling tube, the flexible measuring tape body 1 can be bent and kept in the same state as the indwelling tube for matching. Then, the length of the indwelling tube can be determined by reading the corresponding scale line 2 at the end of the indwelling tube.
[0039] Since the cross-section of the plastic measuring tape body 1 is circular and multiple scale lines 2 are provided, with multiple scale lines 2 spaced around the circumference of the plastic measuring tape body 1, that is, the scale lines 2 are visible from the outer circumference of the plastic measuring tape body 1 at 360°, no matter what shape the plastic measuring tape body 1 is bent into, medical staff can easily read the corresponding degree from the plastic measuring tape body 1, which solves the problem that the existing measuring tools have low accuracy in measuring the length of bent indwelling tubes and are inconvenient to read.
[0040] like Figure 1 and Figure 2 As shown, the plastic measuring tape body 1 includes a protective layer 11 and a plastic measuring core 12. The protective layer 11 wraps around the outer periphery of the plastic measuring core 12, and the scale lines 2 are set on the protective layer 11.
[0041] Specifically, the malleable measuring core 12 is made of malleable material, such as aluminum, lead or copper, so that it can be adjusted and maintained in the same shape as the indwelling tube by medical staff.
[0042] The protective layer 11 is a silicone protective layer, which not only prevents the plastic measuring core 12 from directly contacting the indwelling tube, but also has the advantages of disinfection resistance, chemical stability and excellent tactile feel.
[0043] In order to provide dimensional accuracy of the scale line 2 on the protective layer 11, the thickness of the protective layer 11 is between 0.1 mm and 0.3 mm.
[0044] Within this size range, the deformation of the silicone due to drastic temperature changes is very small and negligible, and will not significantly reduce the accuracy of the measurement.
[0045] like Figure 1 , Figure 2 and Figure 3 As shown, the scale line 2 includes a first scale line 21 and a second scale line 22; multiple first scale lines 21 are provided, and multiple first scale lines 21 are provided on the protective layer 11 along the axial direction of the protective layer 11, and multiple first scale lines 21 are arranged at intervals around the circumference of the protective layer 11; multiple second scale lines 22 are provided, and multiple second scale lines 22 are provided on the protective layer 11 along the axial direction of the protective layer 11, and multiple second scale lines 22 are arranged at intervals around the circumference of the protective layer 11; wherein, the first scale line 21 and the second scale line 22 are respectively provided at both ends of the plastic measuring tape body 1, and extend from both ends to the opposite direction.
[0046] Specifically, the zero mark of the first scale line 21 and the zero mark of the second scale line 22 are respectively set at both ends of the protective layer 11. The first scale line 21 extends toward the zero mark of the second scale line 22, and the second scale line 22 extends toward the zero mark of the first scale line 21.
[0047] The setting of the first scale line 21 and the second scale line 22 enables the shapeable 360° visible flexible tape measure to be used for measurement from any end, eliminating the need for medical staff to first find the end where the zero scale line is located for each measurement, thus improving the overall convenience of using the shapeable 360° visible flexible tape measure.
[0048] Furthermore, a reminder gap is provided between the end of the first scale line 21 near the second scale line 22 and the end of the second scale line 22 near the first scale line 21, so that medical staff can quickly distinguish the boundary between the first scale line 21 and the second scale line 22.
[0049] like Figure 1 , Figure 2 and Figure 3 As shown, the first scale line 21 includes a first zero scale unit 211 and a plurality of first digital scale units 212. The first zero scale unit 211 is disposed at one end of the protective layer 11, and the plurality of first digital scale units 212 are spaced apart along the axial direction of the protective layer 11. Each first digital scale unit 212 is used to indicate the distance between its position and the first zero scale unit 211.
[0050] The second scale line 22 includes a second zero scale unit 221 and a plurality of second digital scale units 222. The second zero scale unit 221 is disposed at the other end of the protective layer 11, and the plurality of second digital scale units 222 are spaced apart along the axial direction of the protective layer 11. Each second digital scale unit 222 is used to indicate the distance between its position and the second zero scale unit 221.
[0051] Specifically, the first zero-scale unit 211 and the second zero-scale unit 221 are respectively disposed at both ends of the protective layer 11.
[0052] The different first digital scale units 212 on each first scale line 21 represent different digital information, and the size of the numbers on the digital information gradually increases in the direction away from the first zero scale unit 211.
[0053] Similarly, the different second digital scale units 222 on each second scale line 22 represent different digital information, and the size of the numbers on the digital information gradually increases in the direction away from the second zero scale unit 221.
[0054] When medical staff use the end with the first zero scale unit 211 to make a measurement, they will align the end with the first zero scale unit 211 with the starting measurement part of the indwelling tube, and bend the plastic measuring tape body 1 into the shape of the part of the indwelling tube to be measured. Then, the length from any position on the indwelling tube to the starting measurement part of the indwelling tube can be understood by observing the digital information of the corresponding first digital scale unit 212.
[0055] When medical staff use the end equipped with the second zero-scale unit 221 to perform measurements, the measurement method is the same as described above, and will not be repeated here.
[0056] like Figure 1 , Figure 2 and Figure 3 As shown, the first digital scale unit 212 is provided with multiple units spaced apart around its circumference.
[0057] Specifically, multiple first scale lines 21 are arranged at circumferential intervals around the body of the malleable measuring tape 1.
[0058] Furthermore, the first digital scale units 212 with the same size of digital information on multiple first scale lines 21 are located on the circumference of the same cross-sectional circle of the protective layer 11, ensuring that when medical staff use the first scale line 21 to measure length, they can accurately read the corresponding digital information on the circumference of this cross-sectional circle from any direction, thus ensuring the accuracy of the measurement of the shapeable 360° visible flexible tape measure.
[0059] like Figure 1 , Figure 2 and Figure 3 As shown, multiple second digital scale units 222 are spaced apart around their circumference.
[0060] Specifically, multiple second scale lines 22 are arranged at circumferential intervals around the body of the malleable measuring tape 1.
[0061] Furthermore, the second digital scale units 222 with the same size of digital information on multiple second scale lines 22 are located on the circumference of the same cross-sectional circle of the protective layer 11, ensuring that when medical staff use the second scale line 22 to measure length, they can accurately read the corresponding digital information on the circumference of this cross-sectional circle from any direction, thus guaranteeing the accuracy of the 360° visible flexible tape measure.
[0062] like Figure 1 , Figure 2 and Figure 3 As shown, the first digital scale unit 212 includes a first coarse digital scale 2121 and a first subdivision digital scale 2122. The first coarse digital scale 2121 is arranged at intervals along the axial direction of the protective layer 11, and the first subdivision digital scale 2122 is arranged between two adjacent first coarse digital scales 2121.
[0063] Specifically, the first coarse division number scale 2121 includes a first coarse division scale line 2121a and a first coarse division number 2121b, with the first coarse division number set at one end of the first coarse division scale line 2121a.
[0064] The size of the numbers on the first coarse division number 2121b gradually increases in the direction away from the first zero scale unit 211.
[0065] The first subdivision numeral 2122 is the first subdivision scale line 2, and the line thickness and length of the first coarse scale line 2121a are both greater than the line thickness and length of the first subdivision scale line 2.
[0066] Multiple first subdivision numerals 2122 are set between two adjacent first coarse division numerals 2121.
[0067] In this embodiment, the size of the first coarse division number 2121b is a multiple of five. Taking the length of the first scale line 21 as 30 centimeters as an example, the sizes of the numbers on the first coarse division number 2121b in the direction away from the first zero scale unit 211 are 5, 10, 15, 20...300 respectively.
[0068] Four first subdivision numerals 2122 are provided between two adjacent first coarse numerals 2121. The distance between two adjacent first subdivision numerals 2122, the distance between adjacent first subdivision numerals 2122 and the first coarse numeral line 2121a, and the distance between adjacent first zero numeral unit 211 and the first subdivision numeral 2122 are all 1 mm.
[0069] like Figure 1 , Figure 2 and Figure 3 As shown, the second digital scale unit 222 includes a second coarse digital scale 2221 and a second fine digital scale 2222. The second coarse digital scale 2221 is spaced apart along the axial direction of the protective layer 11, and the second fine digital scale 2222 is disposed between two adjacent second coarse digital scales 2221.
[0070] Specifically, the second coarse division number scale 2221 includes a second coarse division scale line 2221a and a second coarse division number 2221b, with the second coarse division number set at one end of the second coarse division scale line 2221a.
[0071] The size of the numbers on the second coarse division number 2221b gradually increases in the direction away from the second zero division unit 221.
[0072] The second subdivision scale 2222 is the second subdivision scale line 2. The line thickness and length of the second coarse scale line 2221a are both greater than those of the second subdivision scale line 2.
[0073] Multiple second subdivision numerals 2222 are set between two adjacent second coarse division numerals 2221.
[0074] In this embodiment, the size of the second coarse division number 2221b is a multiple of five. Taking the length of the second scale line 22 as 30 centimeters as an example, the sizes of the numbers on the second coarse division number 2221b in the direction away from the second zero scale unit 221 are 5, 10, 15, 20...300 respectively.
[0075] Four second subdivision numerals 2222 are provided between two adjacent second coarse numerals 2221. The distance between two adjacent second subdivision numerals 2222, the distance between adjacent second subdivision numerals 2222 and the second coarse numeral line 2221a, and the distance between adjacent second zero numerals 221 and the second subdivision numerals 2222 are all 1 mm.
[0076] like Figure 1 , Figure 2 and Figure 3 As shown, the colors of the multiple first digital scale units 212 arranged at intervals along the axial direction of the protective layer 11 are alternated.
[0077] Specifically, to facilitate medical staff to quickly identify digital information, the colors of the multiple first coarse-division digital scale units 2121 on each first scale line 21 are alternated. In this embodiment, red and blue are alternated.
[0078] The first subdivision number, 2122, is set to black.
[0079] It should be noted that the multiple first coarse division numerals 2121 on the circumference of the same cross section of the protective layer 11 are the same color.
[0080] For example, the first coarse division number 2121 on the same cross-sectional circumference of the protective layer 11 corresponding to the first coarse division number 2121b being 5 is all blue.
[0081] like Figure 1 , Figure 2 and Figure 3 As shown, the colors of the multiple second digital scale units 222 arranged at intervals along the axial direction of the protective layer 11 are alternated.
[0082] Specifically, the colors of the multiple second coarse division number scales 2221 on each second scale line 22 are set alternately.
[0083] It should be noted that the color setting on the second scale line 22 can be consistent with the color setting on the first scale line 21, that is, it can also use an alternating red and blue setting, or it can be inconsistent with the color setting on the first scale line 21, that is, it can use an alternating yellow and green setting or other alternating color settings.
[0084] In this embodiment, the color setting on the second scale line 22 also adopts an alternating red and blue setting.
[0085] Furthermore, the second subdivision number 2222 is also set to black.
[0086] It should be noted that the multiple second coarse division numerals 2221 on the circumference of the same cross section of the protective layer 11 are the same color.
[0087] In summary, a shapeable 360° visible flexible measuring tape includes a malleable measuring tape body 1 and scale lines 2. The cross-section of the malleable measuring tape body 1 is circular; multiple scale lines 2 are provided, all of which are arranged along the axial direction of the malleable measuring tape body 1, and the multiple scale lines 2 are spaced apart around the circumference of the malleable measuring tape body 1.
[0088] When using a shapeable 360° visible flexible measuring tape to measure the length of a bent indwelling tube, the flexible measuring tape body 1 can be bent into the same state as the indwelling tube for matching. Then, the length of the indwelling tube can be determined simply by reading the degree of the corresponding scale line 2 at the end of the indwelling tube.
[0089] Since the cross-section of the plastic measuring tape body 1 is circular and multiple scale lines 2 are provided, with multiple scale lines 2 spaced around the circumference of the plastic measuring tape body 1, that is, the scale lines 2 are visible from the outer circumference of the plastic measuring tape body 1 at 360°, no matter what shape the plastic measuring tape body 1 is bent into, medical staff can easily read the corresponding degree from the plastic measuring tape body 1, which solves the problem that the existing measuring tools have low accuracy in measuring the length of bent indwelling tubes and are inconvenient to read.
[0090] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.
[0091] It should be noted that this utility model uses a shapeable 360° visible flexible tape measure as an example to introduce the specific structure and working principle of this utility model.
