Description

Technical Field

[0001] This utility model belongs to the field of limb volume measurement, specifically relating to a device for measuring the volume of limbs. Background Technology

[0002] Measuring basic body dimensions can assess a person's growth and development, nutritional status, and reflect changes in muscle volume or the presence of edema. Commonly used methods for measuring limb volume include the Archimedes-based displacement method, resin transfer molding, CT and MRI methods, and two-dimensional non-contact measurement methods. However, these methods have the following limitations:

[0003] (1) The drainage method is the gold standard for measuring limbs, but the current measurement method is not standardized or uniform, and the measuring device is not precise or convenient enough; (2) The resin transfer molding method requires the introduction of external pressure and is relatively complicated to operate; (3) CT and MRI are difficult to be widely used in clinical practice due to cost, time, patient compliance, radiation and other factors; (4) Among the traditional two-dimensional non-contact measurement methods, the most commonly used is the digital photo measurement method, but it is easily affected by the resolution accuracy, shooting angle and other limitations.

[0004] In summary, current methods for measuring limb volume have certain limitations. Utility Model Content

[0032] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0033] It should be noted that, in this utility model, the top, bottom, left, and right in the figure are regarded as the top, bottom, left, and right of the device for measuring the volume of limbs described in this specification.

[0034] Exemplary embodiments of the present invention are now described with reference to the accompanying drawings. However, the present invention may be embodied in many different forms and is not limited to the embodiments described herein. These embodiments are provided to fully and completely disclose the present invention and to fully convey its scope to those skilled in the art. The terminology used in the exemplary embodiments shown in the drawings is not intended to limit the present invention. In the drawings, the same units / elements are referred to by the same reference numerals.

[0035] Unless otherwise stated, the terms used herein (including technical terms) have their common meaning as understood by one of ordinary skill in the art. Furthermore, it is understood that terms defined in commonly used dictionaries should be understood to have a meaning consistent with the context of their relevant field, and not to be interpreted as having an idealized or overly formal meaning.

[0036] This embodiment relates to a device for measuring the volume of limbs. Please refer to [link to relevant documentation]. Figure 1 It includes a double-layer water tank measuring section 10, a funnel-shaped receiving section 20, and a weighing device 30. The funnel-shaped receiving section 20 and the weighing device 30 are both located inside the double-layer water tank measuring section 10, and the funnel-shaped receiving section 20 and the weighing device 30 are arranged vertically.

[0037] The double-layer water tank measuring section 10 allows limbs to be inserted and overflows, thus occupying the volume of the limbs.

[0038] Specifically, the double-layer water tank measuring unit 10 is composed of an inner water tank 12 and an outer water tank 11. That is:

[0039] The double-layer water tank measuring unit 10 includes an outer water tank 11, which is a hollow cylinder. The double-layer water tank measuring unit 10 also includes an inner water tank 12, which is attached to the hollow cylinder of the outer water tank 11. The inner water tank 12 is suitable for limbs to be inserted into. The inner water tank 12 is a hollow structure with a closed bottom and an open top, so that the overflow liquid from the top opening enters the annular space between the inner water tank 12 and the outer water tank 11.

[0040] In some embodiments, such as Figure 1 As shown, the inner water tank 12 is a frustum-shaped structure that is thicker at the bottom and thinner at the top. The top opening of the frustum is shaped like a plum blossom to guide the overflow liquid. Alternatively, the top opening of the inner water tank 12 is wavy (wavy and plum blossom are synonymous here), and the overflow liquid is guided out from the wavy opening, which facilitates the subsequent accurate measurement of the overflow liquid volume.

[0041] After the inner water tank 12 and the outer water tank 11 are fitted together, they form an annular cavity (or annular space). The inner water tank 12 is filled with liquid (usually water). When the limb is slowly placed into the inner water tank 12, the liquid in the inner water tank 12 overflows and flows into the annular cavity through the plum blossom-shaped opening, thereby preventing water droplets from leaking out and water loss.

[0042] To prevent water loss, the top opening of the outer water tank 11 can be higher than the top opening of the inner water tank 12.

[0043] Furthermore, in this embodiment, the reason for hanging the inner water tank 12 inside the hollow cylinder of the outer water tank 11 is to facilitate the replacement of the inner water tank 12.

[0044] In some embodiments, the inner water tank 12 and the outer water tank 11 can be made as a single unit, but it must be ensured that the overflow water from the inner water tank 12 can smoothly enter the funnel-shaped receiving part 20.

[0045] Please continue reading. Figure 1 A funnel-shaped receiving part 20 is disposed below the double-layer water tank measuring part 10. The funnel-shaped receiving part 20 is suitable for receiving overflow liquid from the double-layer water tank measuring part 10 after a limb is inserted. Specifically, the funnel-shaped receiving part 20 includes:

[0046] The funnel 21 is located inside the hollow cylinder of the outer water tank 11 and below the inner water tank 12. The large-diameter end of the funnel 21 is fixed to the inner wall of the outer water tank 11, and the small-diameter end of the funnel 21 extends into the weighing device 30.

[0047] The inner water tank 12 is filled with liquid (usually water). When the limb is slowly placed into the inner water tank 12, the liquid overflows from the inner water tank 12 and flows into the annular cavity through the plum blossom-shaped opening. The overflow liquid in the annular cavity is quickly collected and gathered along the inner wall of the funnel 21 to the weighing device 30.

[0048] That is, in this embodiment, the funnel-shaped receiving part 20 serves to quickly collect and gather overflowing water droplets, facilitating weighing by the weighing device 30 below. This solves the problems of step-by-step measurement and insufficient weighing in traditional limb measurement, and avoids the shortcomings of traditional measuring cups, measuring cylinders, and inaccurate visual estimation.

[0049] Please continue reading. Figure 1 The weighing device 30 is disposed below the funnel-shaped receiving part 20 to weigh the overflow liquid from the funnel-shaped receiving part 20. Specifically, the weighing device 30 includes a liquid storage cylinder 31 arranged vertically and a weighing scale 32.

[0050] The liquid storage cylinder 31 is located below the small-diameter end of the funnel 21 to receive the overflow liquid flowing out of the funnel 21. The liquid storage cylinder 31 is a cylindrical structure with a closed bottom and an open top. The small-diameter end of the funnel 21 extends into the top opening of the liquid storage cylinder 31.

[0051] The inner water tank 12 is filled with liquid (usually water). When the limb is slowly placed into the inner water tank 12, the liquid overflows from the inner water tank 12 and flows into the annular cavity through the plum blossom-shaped opening. The overflow liquid in the annular cavity is quickly collected and gathered into the storage cylinder 31 along the inner wall of the funnel 21. The weighing scale 32 below the storage cylinder 31 weighs the overflow liquid in the storage cylinder 31.

[0052] In some embodiments, please continue reading Figure 1A sealed drain outlet 311 is provided on the wall of the liquid storage cylinder 31, and the sealed drain outlet 311 is close to the bottom sealing plate of the liquid storage cylinder 31. The sealed drain outlet 311 refers to a drain outlet with a sealing head. This sealed drain outlet 311 facilitates water replacement, effectively solves the problem of inconvenient water replacement and drainage in traditional devices, avoids cross-infection between measurers, and realizes the integration, precision and simplicity of limb volume measurement.

[0053] The weighing scale 32 is located at the bottom of the liquid storage cylinder 31 to weigh the overflow liquid in the liquid storage cylinder 31. That is, the weighing scale 32 can directly weigh and read the volume of water flowing in.

[0054] To facilitate observation and reading of the weighing value of the weighing scale 32, the outer water tank 11 is made of transparent material so that the weighing value of the weighing device 30 can be observed.

[0055] This invention proposes a device for measuring the volume of limbs, mainly composed of a double-layer water tank measuring section, a funnel-shaped receiving section, and a weighing device. The double-layer water tank measuring section consists of an inner water tank and an outer water tank nested together. In use, the limb is slowly placed into the inner water tank filled with water. Water overflows and flows into the funnel-shaped receiving section connected to the outer water tank, preventing water leakage and loss. The weighing device below the funnel-shaped receiving section directly weighs and reads the volume of the flowing water. The liquid storage cylinder of the weighing device has a sealed drain outlet. After use, the accumulated water can be drained through the sealed drain outlet, effectively solving the problems of inconvenient water changing and drainage in traditional devices and avoiding cross-infection between users.

[0056] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
