Description
Technical Field
The invention relates to the field of angle measurement, in particular to a nursing training amplitude and angle monitoring device.
Background
The human body elbow joint motion sensing is to realize real-time detection of the elbow joint motion angle by acquiring a corner signal during motion through a sensor capable of monitoring elbow joint motion. At present, a plurality of sensors can be applied to elbow joint movement, and the sensors relate to the fields of industries such as machining, aerospace, intelligent robots and the like. Due to the diversity of angle measurement and the limitation of angle measurement, further improvement and development are needed in the application field.
In view of this, various elbow joint angle measurement sensors have been proposed in the prior art, and are broadly classified into contact angle measurement and non-contact angle measurement in terms of sensing principle. Contact angle measurement typically involves mechanical means attached to the elbow joint, and angular detection of the mechanical means is achieved by means of angle sensors, such as resistive angle sensors, inductive angle sensors, angle encoders. The resistance-type angle sensor has the advantages of simple mechanical structure, wide measurement range, stable output signal and strong anti-interference capability, and the service life of the sensor is very short due to the contact friction; the inductive angle sensor has the measuring angle of 0-360 degrees, the precision of 0.02-0.05 degrees, low requirement on environment, convenient use, strong anti-interference capability and stable performance, but the structure is relatively complex; the coded angle sensor can measure 0-360 degrees, and the resolution can reach 0.001 degrees, and is characterized by high resolution, high precision, easy digitization, long service life, low power consumption and high reliability.
However, for certain scenarios, it is desirable to apply a stretching force at the end of the range of motion after the human elbow joint has been opened to its maximum angle, at which point it may be induced to plastically deform (permanently elongate) due to the physical properties of the elbow joint itself, and then advance to a fixed position, and so on, to achieve a progressively increasing angle of articulation. At present, a test instrument capable of effectively measuring whether the opening angle of the joint reaches the maximum value is absent in the market, a user needs to judge the movement angle according to experience, and the method is limited by clinical experience of the user and is not easy to popularize.

When the angle between the small arm fixing plate 110 and the large arm fixing plate 220 is increased, the arm of the patient tends to be straightened by the device, and when the angle between the small arm fixing plate 110 and the large arm fixing plate 220 is decreased, the arm of the patient tends to be bent by the device.
When the arm of the patient tends to be straightened or bent to a certain degree, and the patient cannot further change along with the change of the angle between the small arm fixing plate 110 and the large arm fixing plate 220 due to the self-illness of the patient, the sliding block 213 on the large arm assembly slides on the large arm fixing plate 220, then the sliding block 213 slides to drive the connecting plate 231 to slide in the mounting cavity through the linkage plate 211, and the connecting plate 231 drives the pushing plate 232 to slide on the reciprocating frame 242 through the linkage cylinder 233 when sliding. In the sliding process of the pushing plate 232, the pushing plate 232 slides along the inclined plane on one side of the triangular blocks 271 until the pushing plate 232 no longer extrudes the triangular blocks 271, and the triangular blocks 271 and the reciprocating toothed plates 260 have repulsive force under the action of the magnet, that is, the triangular blocks 271 and the reciprocating toothed plates 260 do not contact any more, so that the toothed column 273 retracts into the reciprocating toothed plates 260. Since the reciprocating gear 250 is always engaged with the three tooth columns 273, the reciprocating gear 250 is clamped with the clamping grooves 274 of the three tooth columns 273, so that the three tooth columns 273 engaged with the reciprocating gear 250 are not retracted into the reciprocating toothed plate 260. When the remaining tooth columns 273 are all retracted into the reciprocating tooth plate 260, the reciprocating gear 250 continues to rotate and rotates to the other side of the tooth columns 273, thereby changing the sliding direction of the reciprocating tooth plate 260. When the sliding direction of the reciprocating toothed plate 260 is changed, the small arm fixing plate 110 starts to rotate in the opposite rotating direction, so that the sliding block 213 returns to the initial state, and the pushing plate 232 pushes the triangular block 271 again from the inclined surface on the other side of the triangular block 271 under the action of the linkage plate 211, the connecting plate 231 and the linkage cylinder 233, so that the triangular block 271 contacts with the reciprocating toothed plate 260, and all the toothed columns 273 extend out of the reciprocating toothed plate 260. Because the elastic member 272 is arranged between the triangular block 271 and the tooth column 273, the thrust force on the reciprocating gear 250 is avoided in the process of extending the tooth column 273, so that the effect of protecting the reciprocating gear 250 is achieved.
When the small arm fixing plate 110 swings back and forth, the two first shifting levers 151 and the second shifting lever 161 are driven by the shifting block 120 to rotate around the hinge shaft 130, and finally, the included angle between the first shifting lever 151 and the second shifting lever 161 is read through the scale ring 140.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
