Description

Wearable cervical spine range of motion measurement instrument

Technical Field

The utility model relates to the technical field of cervical vertebra activity detection, in particular to a wearable cervical vertebra activity measuring instrument.

Background Art

The cervical spine, like the thoracic and lumbar vertebrae, is part of the spine. The range of motion of the cervical spine is an important indicator for quantifying cervical function and evaluating cervical diseases, cervical injury, and postoperative recovery. During the rehabilitation process of many cervical injuries, the range of motion of the cervical spine needs to be measured to facilitate medical staff to understand the patient's recovery progress. Existing measurement methods include: visual inspection, soft tape measurement, measuring instrument measurement, etc.

Chinese patent publication number CN214048819U discloses an axis-based calibratable cervical vertebrae range of motion measuring instrument. This scheme facilitates fixing a measuring cap on the patient's head through the design of a first fixing strap, a second fixing strap, a first Velcro and a second Velcro. Through the design of a second rotating shaft, the measuring cap can be rotated with the second rotating shaft as the axis, and then the rotation degree of the cervical vertebra is measured. Through the design of a first mounting plate, a second mounting plate and a first rotating shaft, the measuring cap can be rotated with the first rotating shaft as the axis, and then the left and right deflection degree of the cervical vertebra is measured. This axis-based calibratable cervical vertebrae range of motion measuring instrument has a reasonable design and is simple to operate, and can meet the measurement needs of patients.

However, the measurement accuracy of the left and right movable angle of the patient's cervical spine is not high and the error is large. This is because when the patient's cervical spine is rotating left and right, if the rotation range is not large, the measured value is relatively accurate. If the rotation range is large and the patient is not paying attention, the shoulders on both sides will also rotate accordingly. This will cause the cervical spine, which can only rotate 30 degrees, to rotate 40 degrees when the shoulders also rotate accordingly. The error is large and the measurement effect is not good.

Therefore, it is necessary to provide a wearable cervical vertebrae activity measuring instrument with higher measurement accuracy.

DETAILED DESCRIPTION

Please refer to Figures 1 to 6. In the embodiment of the utility model, a wearable cervical vertebra activity measuring instrument comprises a fixing plate 1, the fixing plate 1 is fixedly connected with a strap 2, the fixing plate 1 is provided with a slide groove 101, a lifting plate 3 is movably connected in the slide groove 101, a connecting rod 4 is fixedly connected to one side of the lifting plate 3, a measuring plate 5 is fixedly connected to one end of the connecting rod 4 away from the lifting plate 3, a scale line 51 is provided on the measuring plate 5, a measuring cap 6 is movably adapted and connected to the lower part of the measuring plate 5, the measuring cap 6 is rotatably connected to the measuring plate 5, a round rod 7 is fixedly connected to the upper part of the measuring cap 6, a pointer 8 is fixedly connected to the round rod 7, the pointer 8 is in contact with the scale line 51, and a limiting component 9 is axially symmetrically arranged on both sides of the fixing plate 1; when it is necessary to measure the cervical vertebra activity of a patient, the fixing plate 1 is placed on the back of the patient and the fixing plate 1 is tied to the patient by the strap 2, the patient's head is put on the measuring cap 6, and the patient's head turning to the left and right directions will drive the measuring The cap 6 rotates, and the rotation of the measuring cap 6 drives the round rod 7 to rotate, and the rotation of the round rod 7 drives the pointer 8 to rotate on the surface of the measuring plate 5. The medical staff judges the rotation range of the patient's cervical vertebra by the stop position of the pointer 8 on the scale line 51 of the measuring plate 5, so as to analyze the recovery effect of the patient's cervical vertebra. In addition, the measuring cap 6 will drive the limit component 9 to work during the rotation of the patient's head, and the limit component 9 will limit the shoulder position of the patient during the patient's head rotation to prevent the patient's shoulder from rotating during the head rotation, thereby causing inaccurate cervical spine activity detection data of the patient. The lifting plate 3 can adjust the height of the connecting rod 4 by moving up and down in the slide groove 101. The height change of the connecting rod 4 drives the height of the measuring plate 5 and the measuring cap 6 to change at the same time. Because the height ratio of the patients is different, the height of the measuring cap 6 is adjusted to adapt to patients of different heights. This solution uses a relatively simple instrument to achieve accurate measurement of cervical spine activity, and medical staff can measure patients more conveniently.

Referring to Figures 4 and 5, in this embodiment, preferably, a rotation groove 52 is opened in the measuring plate 5, and a connecting ring 10 is fixedly sleeved on the outer side of the round rod 7, and the connecting ring 10 is rotatably connected to the rotation groove 52; the measuring cap 6 rotates with the rotation of the patient's head, and the rotation of the measuring cap 6 drives the round rod 7 to rotate, and the rotation of the round rod 7 drives the connecting ring 10 to rotate in the rotation groove 52. The connecting ring 10 is movably arranged in the rotation groove 52, which can not only provide support for the measuring cap 6, but also ensure that the rotation of the measuring cap 6 with the rotation of the patient's head is a rotation that occurs on the same plane without tilting, so that the accuracy of the measurement can be guaranteed, because the connecting ring 10 is movably fitted with the rotation groove 52.

1 and 6, in the present embodiment, preferably, the limit assembly 9 comprises a bracket 91, a first rotating rod 92 is movably provided on the bracket 91, one end of the first rotating rod 92 is fixedly connected to a gear 93, one end of the first rotating rod 92 away from the gear 93 is fixedly connected to a first bevel gear 94, one side of the first bevel gear 94 is meshingly connected to a second bevel gear 95, a second rotating rod 96 is fixedly provided through the center of the second bevel gear 95, one end of the second rotating rod 96 is rotatably connected to the bracket 91, the other end of the second rotating rod 96 is of a screw-shaped design and is movably connected to a pressure plate 97, the pressure plate 97 is provided to prevent the pressure plate from being pressed. The pressure plate 97 is slidably connected to the bracket 91; when the patient wears the measuring cap 6 and turns his head for measurement, the gear 93 is rotated, and the rotation of the gear 93 drives the first rotating rod 92 to rotate, and the rotation of the first rotating rod 92 drives the first bevel gear 94 to rotate, and the rotation of the first bevel gear 94 drives the second bevel gear 95 to rotate, and the rotation of the second bevel gear 95 drives the second rotating rod 96 to rotate, and the rotation of the second rotating rod 96 drives the pressure plate 97 to move, thereby pressing and limiting the patient's shoulder position to prevent the patient's shoulder from rotating when the head is rotated to a large extent, thereby affecting the measurement result, and the bracket 91 provides support.

Referring to FIGS. 3 and 4 , in the present embodiment, preferably, only a semicircular area on the outer side of the measuring cap 6 is fixedly provided with an incomplete gear 11. In the initial state, the incomplete gear 11 is close to the fixing plate 1, and the incomplete gear 11 is transmission-connected with the gear 93. When the patient wears the measuring cap 6 and turns his head to the left first, the measuring cap 6 rotates counterclockwise, and the counterclockwise rotation of the measuring cap 6 drives the incomplete gear 11 to rotate counterclockwise, thereby meshing with the gear 93 on the right side and driving the gear 93 to rotate. The rotation of the gear 93 drives the side pressing plate 97 to press and limit the position of the patient's right shoulder. Because when a person turns his neck to the left, when the rotation amplitude is large, the right shoulder may inadvertently rotate accordingly, so the incomplete gear 11 is rotated counterclockwise. The cooperation between the full gear 11 and the gear 93 can realize the limitation of the right shoulder, which can effectively improve the accuracy of the measurement results. At the same time, the incomplete gear 11 will not mesh with the gear 93 on the left during the process, so the pressure plate 97 on the left will not change. When the left test is completed, the patient's head rotates to the initial state, and the right pressure plate 97 also returns to its original state. Similarly, when the patient wears the measuring cap 6 and turns to the right, the clockwise rotation of the measuring cap 6 will also drive the incomplete gear 11 to mesh with the gear 93 on the left, so that the pressure plate 97 on the left can limit the patient's left shoulder, thereby ensuring the accuracy of the measurement data. The rotation of the measuring cap 6 can drive the pressure plate 97 to limit the patient's shoulder, making the overall operation faster and more convenient.

Referring to Figures 1 and 3, in the present embodiment, preferably, a limiting plate 12 is provided on the side of the bracket 91 away from the pressure plate 97, and the limiting plate 12 is fixedly connected with a moving rod 13, and the moving rod 13 is threadedly connected to the bracket 91; when the patient wears the measuring cap 6 and is ready to be measured, the patient's chest is toward the position of the pressure plate 97, and the back is toward the limiting plate 12. The moving rod 13 is rotated first. Since the moving rod 13 and the bracket 91 are threadedly connected, the moving rod 13 will drive the limiting plate 12 to move toward the patient's back until it contacts the back. Then, during the rotation of the patient wearing the measuring cap 6, the pressure plate 97 will be driven to limit the patient's shoulders, that is, the pressure plate 97 and the limiting plate 12 limit both the front and back of the patient, further avoiding the rotation of the shoulders.

Referring to Figure 3, in this embodiment, preferably, a plurality of through holes 31 are formed on the lifting plate 3, a fixing hole 102 is formed on the fixing plate 1 at the position of the slide slot 101, the through hole 31 is aligned with the fixing hole 102, and a screw 14 is movably engaged with the through hole 31 and the fixing hole 102; when it is necessary to adjust the height of the measuring cap 6 to adapt to patients of different heights, first release the limiting effect of the screw 14 and the through hole 31 and the fixing hole 102, and then move the lifting plate 3 up and down in the slide slot 101, and when the height of the measuring cap 6 is appropriate, align the through hole 31 at the height with the fixing hole 102, and fix it by screwing the screw 14 into the fixing hole 102 in the through hole 31 to ensure the overall stability during the measurement process.

Referring to FIG. 3 , in the present embodiment, preferably, a connecting rod 15 is fixedly connected between the bracket 91 and the lifting plate 3, and the bracket 91 is slidably arranged on both sides of the fixed plate 1; the adjustment of the height of the lifting plate 3 will drive the bracket 91 to be adjusted up and down through the action of the connecting rod 15, because in this way, the rotation of the measuring cap 6 can drive the rotation of the incomplete gear 11, which will drive the gear 93 to rotate, so that the pressure plate 97 can fix the patient's shoulder, that is, the height adjustment of the lifting plate 3 and the bracket 91 is consistent.

The working principle of the utility model is: when it is necessary to measure the range of motion of the cervical vertebra of the patient, the fixing plate 1 is placed on the back of the patient and the fixing plate 1 is tied to the patient through the strap 2. The patient's head is put on a measuring cap 6. When the patient turns his head to the left and right directions, the measuring cap 6 is driven to rotate. When the patient wears the measuring cap 6 and first turns his head to the left, the measuring cap 6 rotates counterclockwise, and the rotation of the measuring cap 6 drives the round rod 7 to rotate, and the rotation of the round rod 7 drives the pointer 8 to rotate on the surface of the measuring plate 5. The medical staff judges the rotation amplitude of the patient's cervical vertebra by the stop position of the pointer 8 on the scale line 51 of the measuring plate 5, so as to analyze the recovery effect of the patient's cervical vertebra. At the same time, the counterclockwise rotation of the measuring cap 6 drives the incomplete gear 11 to rotate counterclockwise, thereby meshing with the gear 93 on the right side and driving the gear 93 to rotate. The rotation of the gear 93 drives the first rotating rod 92 to rotate, and the rotation of the first rotating rod 92 drives the first bevel gear 94 to rotate. The rotation of the first bevel gear 94 drives the second bevel gear 95 to rotate. The rotation drives the second rotating rod 96 to rotate, and the rotation of the second rotating rod 96 drives the pressure plate 97 to move, thereby pressing and limiting the position of the patient's right shoulder. Because when a person turns his neck to the left, when the rotation amplitude is large, the right shoulder may inadvertently rotate accordingly. Therefore, the right shoulder is limited by the cooperation of the incomplete gear 11 and the gear 93, which can effectively improve the accuracy of the measurement result. At the same time, the incomplete gear 11 will not mesh with the gear 93 on the left during this process, so the pressure plate 97 on the left will not change. When the left test is completed, the patient's head rotates to the initial state, and the right pressure plate 97 also returns to its original state. Similarly, when the patient wears the measuring cap 6 and rotates to the right, the clockwise rotation of the measuring cap 6 will also drive the incomplete gear 11 to mesh with the gear 93 on the left, so that the pressure plate 97 on the left is limited to the patient's left shoulder, ensuring the accuracy of the measurement data. The rotation of the measuring cap 6 can drive the pressure plate 97 to limit the patient's shoulder, making the overall operation faster and more convenient.
