Description

Technical Field

[0001] This utility model belongs to the field of cable equipment technology, and specifically relates to a leg circumference measuring tape. Background Technology

[0002] A medical leg measuring band is a tool specifically designed for the medical field to accurately measure the circumference of a patient's legs.

[0003] Medical leg measuring bands are typically made of non-elastic materials that fit snugly against the patient's legs to accurately measure leg circumference. These bands are widely used in the medical field, playing a crucial role in the diagnosis and treatment of conditions such as lower limb swelling, varicose veins, deep vein thrombosis, and lymphedema.

[0004] With the continuous development of medical technology, medical leg measuring bands are also constantly being innovated and improved. Some medical institutions may even customize special measuring bands to meet individual needs based on the specific circumstances and requirements of patients.

[0005] However, the use of a regular measuring tape to measure leg circumference in clinical practice has several drawbacks: 1. Ordinary measuring tapes have a certain degree of elasticity, which causes errors in the measured values; 2. Ordinary measuring tapes are cumbersome to use and not easy to operate in clinical practice; 3. It requires repeatedly marking the location on the patient's leg with a marker, which affects the appearance.

[0006] Therefore, this application provides a leg circumference measuring tape. This tape employs a handwheel-driven, one-hand-operable measuring structure, combined with a shape-memory metal strip that adaptively wraps around the patient's leg to complete the positioning and measurement process. This solves the technical problem of repeatedly marking the patient's leg with a marker pen in previous measurements. Furthermore, by fixing the measurement position with the shape-memory metal strip and using a compensating measuring tape, the error in measurement values ​​caused by the elasticity of ordinary measuring tapes is reduced. The simple one-handed operation also facilitates simultaneous measurement and data recording. Summary of the Invention

[0007] To achieve the above objectives, the technical solution of this utility model is as follows: A leg circumference measuring tape includes a handwheel; a measuring belt is wound around the outer ring of the handwheel, and the extended end of the measuring belt is synchronously connected to a composite elastic band. The composite elastic band consists of a sleeve and a shape memory metal strip, with the shape memory metal strip installed inside the sleeve. The root of the sleeve is connected to a mating end, and the measuring tape extends into the measuring tape extension hole of the sleeve along the horizontal direction of the mating end.

[0008] Furthermore, a skin-friendly patch is adhered to the bottom end face of the sleeve, and the skin-friendly patch comes into contact with the patient's skin.

[0009] Furthermore, the upper surface of the sleeve retains a measurement gap, and the measurement band displays a measurement scale layer along the measurement gap. The measurement scale layer has a three-dimensional font scale structure.

[0010] Furthermore, the upper and lower end faces of the docking end are provided with measuring band guide grooves, and the measuring band guide grooves and the measuring band extension holes form a guiding extension structure; The two sets of measuring band extension holes are mirror-shaped along the shape memory metal strip.

[0011] Furthermore, the handwheel is composed of an I-beam sleeve, a bearing, and a rubber ring. The bearing is installed on the inner ring of the I-beam sleeve, and the outer ring of the bearing is synchronously connected to the inner ring of the I-beam sleeve. The outer ring of the I-beam sleeve retains a storage groove; The bearing inner ring is fitted with a rubber ring, which comes into contact with the fingers of medical personnel.

[0012] Furthermore, the outer ring of the I-shaped sleeve is fitted with a housing along the storage groove. The housing has a ring-shaped structure, and an encapsulation layer is integrally connected to the outer end face of the housing. The encapsulation layer has a measuring band opening along the arc-shaped outer end face of the housing, and the measuring band extends out along the measuring band opening.

[0013] The beneficial effects of this utility model are as follows: Compared with existing technologies, this application provides a leg circumference measuring tape. This tape employs a handwheel-driven, one-hand-operable measuring structure, combined with a shape-memory metal strip that adaptively wraps around the patient's leg to complete the positioning and measurement process. This solves the technical problem of repeatedly marking the patient's leg with a marker pen in previous measurements. Furthermore, by fixing the measurement position with shape-memory metal and using a compensating measuring tape, the error in measurement values ​​caused by the elasticity of ordinary measuring tapes is reduced. The simple one-handed operation also facilitates simultaneous measurement and data recording. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a leg circumference measuring tape includes a handwheel; a measuring band 11 is wound around the outer ring of the handwheel 3, and the extended end of the measuring band 11 is synchronously connected to a composite elastic band 1. Medical personnel can insert their fingers into the handwheel 3 to prepare for carrying the tape. During use, similar to a snap ring, the composite elastic band 1 automatically wraps around the patient's leg surface, utilizing the material properties of the memory metal band 10. Its self-adhesive structure serves as a preliminary fixing structure, providing convenient positioning for medical personnel to measure the patient's leg circumference. During use, the measuring band 11 can be wound and stretched in accordance with the leg circumference direction, allowing for adaptive supplementary measurements based on different patient leg circumferences.

[0020] The composite elastic band 1 is composed of a sleeve 4 and a shape memory metal strip 10, with the shape memory metal strip 10 installed inside the sleeve 4; wherein, the sleeve 4 and the shape memory metal strip 10 constitute the composite elastic band 1, and the sleeve 4 serves as a soft sleeve structure to protect the shape memory metal strip 10.

[0021] The sleeve 4 is connected to a mating end 5 at its root. The measuring band 11 extends horizontally into the measuring band extension hole 8 of the sleeve 4 along the mating end 5. The measuring band 11, in conjunction with the mating end 5, extends into the measuring band extension hole 8 of the sleeve 4 to perform extended measurements and connect the composite elastic band 1. The double-layer measuring band 11 design maintains the connection balance and structural strength of the composite elastic band 1. The mating end 5 serves as a separator at the root of the sleeve 4, providing protection.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a skin-friendly patch 1-1 is adhered to the bottom end face of the sleeve 4, and the skin-friendly patch 1-1 comes into contact with the patient's skin. The skin-friendly patch 1-1 enhances the patient's user experience and avoids unnecessary allergic reactions.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the upper surface of the sleeve 4 retains a measurement gap, and the measurement band 11 displays the measurement scale layer 1-2 along the measurement gap. The measurement scale layer 1-2 has a three-dimensional font scale structure. The measurement gap exposes the measurement scale layer 1-2, allowing medical personnel to easily observe the scale dimensions. Furthermore, compared to conventional printed flat fonts, the three-dimensional font structure has a longer lifespan and a better user experience.

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the upper and lower end faces of the docking end 5 are provided with measuring belt guide grooves 6, and the measuring belt guide grooves 6 and the measuring belt extension holes 8 form a guiding extension structure; the measuring belt guide groove structure can keep the plane height of the measuring belt 11 lower than the docking end 5, so that unnecessary wear will not be caused by the joint-type structure of the docking end 5 during use.

[0025] Two sets of measuring tape extension holes 8 are mirror-shaped along the shape memory metal strip 10. The mirror-shaped distribution of the measuring tape extension holes 8 keeps the measuring tape 11 in a balanced tension state. The top end of the measuring tape 11 is fixed to the top end of the sleeve 4 to prevent localized curling of the measuring tape 11 from affecting its measurement scale value. This also ensures a good fixed stress point during the winding process.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the handwheel 3 is composed of an I-shaped sleeve 3-1, a bearing 3-2, and a rubber ring 2. The bearing 3-2 is installed on the inner ring of the I-shaped sleeve 3-1, and the outer ring of the bearing 3-2 is synchronously connected to the inner ring of the I-shaped sleeve 3-1. The I-shaped sleeve 3-1 serves as the overall support structure of the handwheel 3, while the bearing 3-2 installed on the inner ring of the I-shaped sleeve 3-1 serves as an auxiliary structure for finger operation, facilitating operation.

[0027] The outer ring of the I-shaped sleeve 3-1 has a storage groove 3-3; the groove 3-3 is for storing the measuring tape 11.

[0028] A rubber ring 2 is installed on the inner ring of the bearing 3-2, and the rubber ring 2 comes into contact with the fingers of medical personnel. The rubber ring 2 is used to protect the fingers of medical personnel.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a housing 12 is installed along the storage groove 3-3 on the outer ring of the I-beam sleeve 3-1. The housing 12 has a ring-shaped structure, and an encapsulation layer 12-2 is integrally connected to the outer end face of the housing 12. The encapsulation layer 12-2 has a measuring band opening 12-1 along the arc-shaped outer end face of the housing 12, and the measuring band 11 extends out along the measuring band opening 12-1. The housing 12 serves as a protective shell structure for the I-beam sleeve 3-1 and the measuring band 11. This prevents the measuring band 11 from scattering due to lack of guidance and also effectively prevents impurities and moisture from entering.

[0030] It should be noted that the above content merely illustrates the technical concept of this utility model and cannot be used to limit the scope of protection of this utility model. For those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and all such improvements and modifications fall within the scope of protection of the claims of this utility model.
