The branch includes finger wearing parts 110: 110a to 110e.

The back of the hand wearing part 120 is a part that is worn on the back of the hand, and the housing 220 of the motion measurement unit 200 is coupled to the back of the hand wearing part 120. Since a plurality of coupling holes are formed in the back of the hand wearing part 120, the coupling protrusion 224 formed in the lower portion of the housing 220 is inserted into and coupled to the coupling hole 121 as shown in FIG. 5.

The back of the hand wearing part 120 is formed in a wide plate shape so as to cover the back of the hand, and is formed of a synthetic material having excellent elasticity. For example, a silicon material may be selected. Silicone is harmless to the human body and has excellent fit and is suitable as a material for the wearing unit 100. As shown in FIG. 4, a plurality of small protrusions 122 are formed on the bottom surface of the back of the hand wearing part 120. It is preferable that a plurality of small protrusions 122 are formed in a hemispherical shape, and a passage through which air can pass is formed in the space between the back of the hand wearing part 120 and the back of the hand, even if the wearing unit 100 is worn for a long time, on the back of the hand.

It can also be used as a rehabilitation device to collect data about the disease and use it for rehabilitation.

Therefore, it is important to be designed to minimize resistance when a patient who is difficult to apply a large force to the finger bends the finger.

In view of this point, it is most preferable that the elastic extension part 111 adopts a meander structure of a grain-like shape that is serpentinely repeated as shown in FIGS. 1 to 4. Compared to the applied force, a large elastic deformation occurs, so that the resistance of the elastic restoring force to the movement of the finger can be minimized.

After the elastic extension part 111, a joint wearing part 112 positioned at the first and second nodes of the finger is formed. It is preferable that the joint wearing part 112 has a joint protrusion 113 for minimizing the deformation of the finger wearing part 110 against bending of the finger joint to minimize resistance to the movement of the wearer's hand. Since the finger wearing unit 110 is located on the finger, etc., when the finger is bent, the most deformation occurs, and the part in which the resistance force is greatest is the joint wearing unit 112. Accordingly, the joint protrusion 113 is formed in the center of the joint wearing part 112 in order to detect the bending of the finger but minimize the elastic deformation. When the finger is bent, a part of the joint is exposed through the joint protrusion 113, and the elastic deformation of the joint wearing part 112 and resistance due to the restoring force are minimized.

A wearing ring 114 is formed below the finger wearing unit 110 so that the finger wearing unit 110 is fixed to the finger. The wearer's finger is inserted into the wearer's ring 114 so that the finger-wearing part 110 is in close contact with the wearer. Since the thickness of the fingers is different for each person, it is preferable that the wearing ring 114 has a structure that can be easily stretched, and the meander structure 115 under the wearing ring 114 is similar to that adopted in the elastic extension part 111 above. ) To facilitate elastic deformation.

The second coupling groove 117 is formed to be located at the second joint of the finger past the joint wearing portion 112.

The first coupling portion 213 and the second coupling portion 216 provided under the first sensor unit 212 and the second sensor unit 214 in the first coupling groove 116 and the second coupling groove 117 ) Is inserted and coupled. As shown in FIG. 7, the first and second coupling portions 213 and 216 have heads formed at the ends to penetrate the first and second coupling grooves 116 and 117 and are not easily removed. Becomes. Since the finger wearing part 110 has elasticity, the first coupling groove 116 and the second coupling groove 117 are easily opened to insert the first coupling part 213 and the second coupling part 216 when combined. I can make it.

When the finger wearing unit 110 is divided according to the finger, the thumb wearing unit 110a, the index finger wearing unit 110b, the middle finger wearing unit 110c, the ring finger wearing unit 110d, and the holding finger wearing unit 110e )to be.

As shown in Fig. 8, the structure of the thumb of the human finger and the other four fingers is slightly different. The thumb consists of two segments, and the index finger or the small finger consists of three segments. Since the thumb has a structure in which the hand hip bone can move easily, a structure that facilitates elastic deformation of the hand hip bone is required. Therefore, between the back of the hand wearing portion and the elastic extension portion 111 of the thumb wearing portion (110a), the hand waist elastic extension portion having a pair of meander structures so as to be elastically deformed according to the movement of the waist portion of the thumb ( It is preferable to further include 118).

A coupling portion having a coupling head 185 is formed in the lower portion of the cable guide, so that the coupling head 185 passes through the coupling hole 119 formed in the thumb wearing portion, and is then engaged and coupled.

Hereinafter, the motion measurement unit 200 will be described with reference to FIGS. 1 to 7 in order to help understand the wearing unit for a finger motion measurement device according to the present invention.

The motion measurement unit 200 includes a battery and a housing 220 containing a control unit 240. As shown in FIG. 2, the housing 220 is designed to be separated and combined into an upper housing 221 and a lower housing 222. A battery and a control unit 240 are built into the housing 220. Here, the control unit 240 includes a control unit (not shown) and a communication module (not shown). The information on the movement of the finger detected by the first and second sensors is received, and the information on the movement of the finger collected from the sensor is transmitted to an external device such as a computer connected through the communication module. The controller may calculate and store the degree of bending of the finger from the signals transmitted from the first and second sensors 2121 and 2141. The communication module can receive signals wirelessly with an external device, and short-range wireless communication methods such as Bluetooth and RF can be applied.

In addition, the control unit 240 may include a geomagnetic sensor and a gyro sensor to measure the movement of the back of the hand or the wrist.

The motion measurement unit 200 includes a finger motion detection unit 210. The finger movement detection unit 210 is a thumb movement detection unit 210a, a middle finger movement detection unit 210b, an index finger movement detection unit 210c, a ring finger movement detection unit 210d, and a holding finger movement detection for each finger. It is divided into a part 210e.

The finger motion detection unit 210 is coupled to the upper portion of the finger wearing unit 110, and is positioned on the first and second nodes of the finger to detect the movement of each finger joint 212 and a second sensor unit 214 and a flexible cable 211 formed along the finger and coupled to the control unit 240 to supply power to the first sensor 2121 and the second sensor 2141.

It is preferable that the flexible cable 211 has a film wire embedded therein, and is manufactured by coating a silicone on the exterior. By thin coating of silicone having excellent elasticity, it is possible to protect the film wire and minimize the resistance to finger movement when the flexible cable 211 is bent according to the bending of the finger. A flex sensor (not shown) may be additionally built into the flexible cable 211. The flex sensor is a sensor that detects the degree of bending according to the measured resistance value because the resistance value varies according to the degree of bending, and may be used together with the first sensor and the second sensor.

The first sensor and the second sensor may select any one of a gyro sensor and a geomagnetic sensor, and the degree of bending of the finger may be measured by measuring the relative positions of the first and second segments of the finger.

A first coupling part 213 is provided under the first sensor part 212. As shown in FIG. 7, the first coupling part 213 is manufactured so that the end is formed larger than the first coupling groove 116 so that it does not get caught after passing through the first coupling groove 116.

A sliding guide 215 through which the flexible cable 211 passes is coupled to the second sensor unit 214. As shown in FIG. 7, the flexible cable 211 passes through the sliding guide 215 and is bent 180 degrees upward at the tip of the finger to form a bending part 219, and the end thereof is a second sensor part 214 ). The reason why the flexible cable 211 forms the bending part 219 is to naturally connect the flexible cable 211 with the second sensor part 214 and at the same time have less resistance to bending of the finger. . It is designed to relatively move the inside of the sliding guide 215 coupled to the lower part of the second sensor, so that the flexible cable 211 is easily bent according to the bending of the finger.

The bending portion 219 of the flexible cable 211 has a cap 218 surrounding the outside of the bending portion 219, and a roller installed inside the cap 218 and located inside the bending portion 219 ( 217 is provided and the flexible cable 211 passes between the cap 218 and the roller 217. The cap 218 and the roller 217 serve to protect the flexible cable bending portion 219 and at the same time serve to help the flexible cable 211 bend naturally.
