Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a movable measuring table for assessing arm circumference in breast cancer patients. Background Technology

[0002] Breast cancer is one of the most common malignant tumors among women in my country, and also one of the most prevalent malignant tumors globally. Early-stage breast cancer is treated primarily with surgery, supplemented by chemotherapy, endocrine therapy, radiation therapy, and targeted biological therapies. Currently, surgery is the preferred treatment method.

[0003] Currently, the incidence of lymphedema is high in breast cancer patients after axillary lymph node dissection. Axillary lymph node dissection is an independent risk factor for postoperative lymphedema in breast cancer patients. Breast cancer patients are at risk of developing lymphedema throughout their lives. Once lymphedema occurs, it consumes a tremendous amount of time, money, and energy, significantly impacting their quality of life. Furthermore, early symptoms of lymphedema are often subtle, making secondary prevention difficult and resulting in low early diagnosis rates. Therefore, clinicians should prioritize the prevention of postoperative lymphedema in breast cancer patients and provide guidance on early detection to facilitate timely treatment. Regular home limb measurement is an effective screening method.

[0004] Upper limb lymphedema is one of the most common complications following axillary lymph node dissection in breast cancer patients. In its mild stages, this complication is difficult to detect, but once it progresses to a severe stage, it can lead to upper limb functional and sensory impairment, and may even cause upper limb tissue necrosis, seriously threatening the patient's quality of life. Currently, many treatment options for upper limb lymphedema lack definitive efficacy; therefore, early diagnosis and timely intervention are crucial for slowing disease progression and preventing the development of severe upper limb lymphedema.

[0005] In the early detection of upper limb lymphedema and the assessment of treatment efficacy, dynamic monitoring of arm circumference changes at fixed sites on the affected upper limb and comparing the arm circumference difference between the affected and unaffected sides are the most effective methods. However, the current routine practice requires patients to visit the hospital regularly for measurements and recording by a specialist nurse. Since patients need bilateral arm circumference measurements for comparison at multiple time points—before surgery, after surgery, and during follow-up—this results in a heavy workload for specialist nurses. Furthermore, using a standard measuring tape is cumbersome in terms of positioning and measurement process, consuming significant manpower and time.

[0006] Chinese patent CN 219501005 U discloses a lymphedema measurement table, which includes a power-adjustable table, a slot, a sliding plate, a height display screen, and a measuring tape. The slot is vertically arranged and installed on the power-adjustable table, and the sliding plate slides within the slot. A measuring tape sliding groove is evenly spaced along the horizontal edge of the slot, through which the measuring tape passes and slides freely. This measurement table primarily uses the sliding plate to align the tip of the middle finger with the fixed measuring tape scale, ensuring the patient maintains the same posture each time their arm circumference is measured, thus improving accuracy and convenience. However, on the one hand, this measurement table cannot be used in the daily follow-up of medical staff due to its lack of flexibility; on the other hand, it still cannot solve the problem of cumbersome positioning during measurement.

[0007] Therefore, there is an urgent need for a device to assess the arm circumference of breast cancer patients, which can improve the accuracy and convenience of measurement and be applied to the daily follow-up of medical staff. Utility Model Content

[0008] The purpose of this invention is to provide a movable measuring table for assessing the arm circumference of breast cancer patients. The table is easy to use and has accurate positioning. It can be used for daily follow-up by medical staff and for regular postoperative lymphedema assessment during outpatient follow-up.

[0009] The objective of this utility model can be achieved through the following technical solutions:

[0010] A movable measuring table for assessing arm circumference in breast cancer patients includes a tabletop, a liftable support column is provided below the tabletop, and movable casters are provided at the bottom end of the liftable support column;

[0011] The tabletop surface is provided with a sliding track along its length, and scales are provided on both sides of the sliding track. A slider is slidably arranged in the sliding track. A first positioning tape measure, a second positioning tape measure, and a third positioning tape measure are arranged at equal intervals along the sliding direction on the surface of the slider, and the distance between adjacent positioning tape measures is 10cm.

[0012] In this invention, the slider, sliding track, and three positioning tape measures can solve the problems of inconvenience and inaccurate positioning when measuring and evaluating the circumference of both arms, as well as the cumbersome process of measuring multiple positioning points, thereby improving the work efficiency of medical staff.

[0013] In this invention, scales are provided on both sides of the sliding track, which can be used to measure the length of the forearm and upper arm of both arms.

[0014] Preferably, the first, second, and third positioning measuring tapes are provided with scales, and the measurement range is 0-60cm. The 0 mark of the scale is located at one end of the first, second, and third positioning measuring tapes.

[0015] Preferably, the slider is provided with a first limiting groove, a second limiting groove, and a third limiting groove at equal intervals along its sliding direction. The opening direction of the first limiting groove, the second limiting groove, and the third limiting groove is perpendicular to the sliding direction of the slider. The distance between adjacent limiting grooves is 10cm. The first positioning tape measure is slidably disposed in the first limiting groove, the second positioning tape measure is slidably disposed in the second limiting groove, and the third positioning tape measure is slidably disposed in the third limiting groove.

[0016] In this invention, the positioning tape measure is slidably set in the limiting groove, which makes it convenient to read the scale on the positioning tape measure during measurement and improves the ease of reading.

[0017] Preferably, the ends of the first, second, and third positioning tape measures are provided with limiting blocks to prevent the positioning tape measures from sliding out of the limiting groove, thus preventing the positioning tape measures from sliding directly out of the limiting groove.

[0018] Preferably, the surface of the limiting block is provided with a magnet buckle, and the inside of the table is provided with a magnetic structure, so that the first positioning tape measure, the second positioning tape measure, and the third positioning tape measure are magnetically attached to the table by the magnet buckle.

[0019] In this invention, when the measuring table is not in use, the three positioning tape measures can be stored on the table using the magnetic buckles on the surface of the limiting blocks, preventing them from dragging on the ground.

[0020] Preferably, the sliding track is further provided with a limiting structure to prevent the slider from falling out.

[0021] More preferably, the limiting mechanism includes guide grooves disposed on both sides of the sliding track, and protruding guide blocks are disposed at corresponding positions on both sides of the slider.

[0022] Preferably, the tabletop includes a connecting plate, a measuring plate, and a writing plate. The sliding rail is set on the measuring plate and is arranged along the length of the measuring plate. The measuring plate and the writing plate are respectively hinged to the connecting plate. The measuring plate and the writing plate can be rotated from 0 to 90 degrees.

[0023] Preferably, the connecting plate is provided with a first hinge portion and a second hinge portion on its adjacent two sides, the hinge axis of the first hinge portion and the hinge axis of the second hinge portion are perpendicular to each other, the measuring plate is hinged to the connecting plate through the first hinge portion, and the writing plate is hinged to the connecting plate through the second hinge portion.

[0024] Preferably, both the first hinge portion and the second hinge portion are hinge-type hinge structures.

[0025] In this invention, when the measuring table is not in use, the measuring board and the writing board can be stored on both sides of the connecting plate through a hinge structure, reducing the space occupied.

[0026] Preferably, the height-adjustable support column is located below the connecting plate of the tabletop, the height-adjustable support column is equipped with a storage basket, and the height of the height-adjustable support column is adjusted by a pneumatic pump switch.

[0027] This invention allows the measuring table to be flexibly adjusted to the patient's armpit using a height-adjustable support column, so that the patient's arm can be placed horizontally on the measuring table, ensuring the accuracy and stability of the patient's position during measurement.

[0028] Preferably, the movable pulley is a swivel wheel, and the swivel wheel is equipped with a locking device, which is used to fix the swivel wheel in place.

[0029] This invention enables the measuring table to move by means of movable pulleys, improving the flexibility of the measuring table. It can be applied to the daily follow-up of medical staff and the regular postoperative lymphedema assessment of patients during outpatient follow-up.

[0030] This invention breaks through the limitations of conventional measuring rulers by modifying the ruler to allow patients to place their arms on a measuring table. The table's height can be adjusted to ensure the patient's arm is perpendicular to their body, improving the accuracy of axillary level measurements. The sliding slider and three positioning tape measures conveniently and accurately record the axillary level, elbow crease, 10 cm above the elbow, 10 cm below the elbow, 10 cm above the wrist crease, wrist crease, the circumference of the web between the thumb and index finger, and the length of the forearm and upper arm of both arms. By comparing these values, it is possible to determine whether the patient has lymphedema on the affected upper limb.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] (1) This utility model provides a movable measuring table for assessing the arm circumference of breast cancer patients.

[0033] (2) In this utility model, the slider is provided with a first positioning tape measure, a second positioning tape measure and a third positioning tape measure at 10cm intervals. When the slider moves in the sliding track, it can drive the three positioning tape measures to move together. In specific measurement, the slider can directly drive the three positioning tape measures to different measurement points to complete 7 fixed point measurements. The number of positioning times is reduced, there is no need for repeated positioning, and the positioning is more accurate, which greatly reduces the measurement time and improves the work efficiency of medical staff.

[0034] (3) In this utility model, by positioning the first positioning tape measure under the patient's armpit, the arm circumference at the axillary level can be measured using the first positioning tape measure; by sliding the slider, the second positioning tape measure can be moved to the center of the patient's elbow, and the elbow crease can be measured using the second positioning tape measure; the arm circumference 10cm above and 10cm below the elbow can be measured using the first positioning tape measure and the third positioning tape measure; by sliding the slider, the third positioning tape measure can be moved to the wrist crease, and the wrist crease circumference and the arm circumference 10cm above the wrist crease can be measured using the third positioning tape measure and the second positioning tape measure; then the circumference of the tiger's mouth can be directly measured using the third positioning tape measure, and the measurement of 7 fixed points can be completed.

[0035] (4) This utility model can also measure the length of the forearm and upper arm of both arms by means of the scale on both sides of the sliding track.

[0036] (5) The height of the measuring table can be flexibly adjusted by the air pressure pump switch, and the measuring table can be conveniently adjusted to the patient's armpit so that the patient's arm can be placed horizontally on the measuring table, ensuring the accuracy and stability of the patient's position during measurement.

[0037] (6) By hingedly connecting the measuring plate and the writing plate to the connecting plate, the table can be stored away when not in use, reducing the space occupied and making it more convenient to carry and move, thus further improving the flexibility of the present invention.
