  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[First Embodiment]
First, with reference to FIG.1 and FIG.2, the structure of the thigh joint automatic exercise | movement assistance apparatus 1 of 1st Embodiment is demonstrated.
FIG. 1 is a diagram illustrating an example of an external configuration of a thigh joint automatic exercise support device 1 according to the first embodiment.
FIG. 2 is a diagram illustrating an example of a functional configuration of the thigh joint automatic exercise support device 1 according to the first embodiment.

The thigh joint automatic movement support device 1 includes a base BS and a screen SC. The base BS is placed in a horizontal direction with respect to the floor surface. The screen part SC is coupled to the base part BS in a direction perpendicular to the floor surface. On the base BS, the feet of the patient in the supine position on the bed are placed. The sole of the patient faces the screen SC.
The base BS includes a heel positioning portion HH and a heel sensor 30. The screen SC includes a control device 10, a toe sensor 20, a display unit 40, a communication unit 50, a spring SPR, and a foot switch FS.

  In the first embodiment, a case where the thigh joint automatic exercise support device 1 is for one leg will be described as an example. The thigh joint automatic movement support device 1 may be for both feet. In this case, the thigh joint automatic movement support device 1 includes two each of the above-described heel positioning unit HH, heel sensor 30, toe sensor 20, spring SPR, and foot switch FS.

  The heel positioning unit HH positions the patient's heel. The scissor positioning part HH is configured by a deformable member such as a sponge and has a scissor-shaped depression. This heel positioning part HH may be exchangeable for each patient.

The heel sensor 30 detects whether or not the heel is positioned at a predetermined position of the heel positioning portion HH. The predetermined position refers to the position of the kite in a state where the kite does not float vertically upward from the base BS. That is, the heel sensor 30 detects whether or not the heel is lifted from the base BS. The heel sensor 30 only needs to be able to detect the lifting of the heel, and any detection method may be used. For example, the wrinkle sensor 30 may be a contact type or an optical type.
In the example shown in the figure, the eyelid sensor 30 is a contact-type switch, and is provided at the bottom of the eyelid positioning portion HH. The heel sensor 30 outputs a signal indicating that the heel is positioned at a predetermined position of the heel positioning portion HH.

  The spring SPR is provided at a position where it hits the sole in a state where the heel is positioned by the heel positioning portion HH. When the heel is positioned by the heel positioning portion HH, the spring SPR urges a force in the dorsiflexion direction of the thigh joint when the foot thigh joint (ankle joint) is bent. The spring SPR biases a force having a magnitude corresponding to the plantar flexion angle of the thigh joint. Specifically, the spring SPR biases a small force in the dorsiflexion direction when the plantar flexion angle of the thigh joint is small. Further, the spring SPR biases a large force in the dorsiflexion direction when the plantar flexion angle of the thigh joint is large.

The foot switch FS is provided at a position where it hits the toe portion in a state where the heel is positioned by the heel positioning portion HH.
The toe sensor 20 detects whether or not the toe part touches the foot switch FS.

Here, in the state where the heel is positioned by the heel positioning portion HH, when the patient does not perform the thigh joint sole bending operation, the toe portion is removed from the foot switch FS by receiving the force of the spring SPR on the sole. Leave. That is, in a state where the heel is positioned by the heel positioning portion HH, if the patient does not apply force to the calf portion (so-called calf), the toe portion is separated from the foot switch FS.
In addition, when the heel is positioned by the heel positioning portion HH, the toe portion comes into contact with the foot switch FS when the patient performs the thigh joint flexion operation against the force of the spring SPR received on the sole.
In other words, the toe sensor 20 detects a change in the position of the toe of the foot on which the heel is positioned by the heel positioning unit HH as a thigh joint floor bending action. When the toe part touches the foot switch FS, the toe sensor 20 outputs a signal indicating that the toe part touches the foot switch FS.

  Note that the toe sensor 20 is an example of a bottom bending detection unit. The plantar flexion detection unit is not limited to the above-described configuration, as long as it can detect the thigh joint sole flexion motion of the foot where the heel is positioned by the heel positioning unit HH. For example, the plantar flexion detection unit may detect the angle of the thigh joint.

  The control device 10 includes a calculation unit 100 and a storage unit 110. The storage unit 110 stores a program used for calculation by the calculation unit 100 and various types of information. The storage unit 110 stores a calculation result by the calculation unit 100.

  The calculation unit 100 includes a central processing unit (CPU) and performs various calculations. The calculation unit 100 acquires a signal output from the toe sensor 20 and a signal output from the heel sensor 30. The calculation unit 100 determines the thigh joint plantar flexion motion based on the acquired signals. For example, the calculation unit 100 counts the number of thigh joint plantar flexion motions. The calculation unit 100 causes the storage unit 110 to store the determination result of the thigh joint floor flexion motion. In addition, the calculation unit 100 outputs the determination result of the thigh joint plantar flexion motion to the display unit 40 and the communication unit 50.

  The display unit 40 includes an LCD (Liquid Crystal Display) and displays characters and images. The display unit 40 can also display the calculation result of the calculation unit 100. When the calculation unit 100 outputs the number of thigh joint plantar flexion operations, the display unit 40 displays the number of thigh joint plantar flexion operations.

  The communication unit 50 includes a wireless communication circuit, and transmits the calculation result of the calculation unit 100 to another device by wireless communication. This other device is a portable communication device such as a smart phone or a tablet.

  The other device may be a computer installed in a nurse station or a server on the cloud. For example, the communication unit 50 transmits the calculation result of the calculation unit 100 to a computer installed in the nurse station. According to the thigh joint automatic exercise support device 1 configured as described above, the exercise status of the patient can be grasped at the nurse station.

[Operation of Control Device 10]
Next, the operation of the control device 10 will be described with reference to FIGS.
FIG. 3 is a diagram illustrating an example of the operation of the control device 10 according to the first embodiment.
FIG. 4 is a diagram illustrating an example of a positional relationship between the thigh joint automatic exercise support device 1 of the first embodiment and a dorsiflexed foot.
FIG. 5 is a diagram illustrating an example of a positional relationship between the thigh joint automatic exercise support device 1 according to the first embodiment and a foot in a plantar bent state.
FIG. 6 is a diagram illustrating an example of a positional relationship between the thigh joint automatic exercise support device 1 of the first embodiment and the foot in a state where the heel is lifted.
4 to 6, the symbol C indicates the patient's foot, the symbol H indicates the heel, and the symbol T indicates the toe.

  The thigh joint automatic movement support device 1 is placed on a patient's bed. The patient is in a supine position on the bed, and after placing the heel on the heel positioning portion HH, the foot is placed on the base BS (FIG. 4). The patient automatically performs thigh joint flexion movement (FIGS. 4 and 5).

The calculation unit 100 determines whether or not a thigh joint plantar flexion motion has been performed in step S10 and step S20. In this example, the arithmetic unit 100 determines that the thigh joint flexion operation has been performed when the toe leaves the foot switch FS after the patient's toe touches the foot switch FS. Note that the calculation unit 100 may determine that the thigh joint flexion operation has been performed when the toe touches the foot switch FS from the state where the patient's toe is separated from the foot switch FS.
Hereinafter, a more specific operation of the calculation unit 100 will be described.

  (Step S <b> 10) The computing unit 100 acquires a signal output from the toe sensor 20. This signal indicates whether or not the toe part touches the foot switch FS. When the signal output from the toe sensor 20 indicates that the toe portion does not touch the foot switch FS (step S10; NO), the arithmetic unit 100 returns the process to step S10. When the signal output from the toe sensor 20 indicates that the toe part is touching the foot switch FS (step S10; YES), the arithmetic unit 100 advances the process to step S20.

(Step S20) The calculation unit 100 further acquires a signal output from the toe sensor 20. When the signal output from the toe sensor 20 indicates that the toe part is touching the foot switch FS (step S20; NO), the arithmetic unit 100 returns the process to step S20. When the signal output from the toe sensor 20 indicates that the toe part does not touch the foot switch FS (step S20; YES), the arithmetic unit 100 advances the process to step S30.
That is, in step S10 and step S20, the arithmetic unit 100 adds the number of thigh joint flexion movements when the detection result by the toe sensor 20 indicates that the position of the toe has changed.

  Next, the calculation unit 100 determines whether or not the heel is not lifted from the base BS after the toe touches the foot switch FS until the toe leaves the foot switch FS. That is, the calculation unit 100 adds the number of thigh joint flexion movements on the condition that the detection result of the heel sensor 30 indicates that the heel is positioned at a predetermined position. More specifically, as shown below.

  (Step S30) The computing unit 100 acquires a signal output from the eyelid sensor 30. This signal indicates whether or not the eyelid is positioned at a predetermined position of the eyelid positioning portion HH. That is, this signal indicates whether or not the kite is not floating from the base BS. When the signal output from the heel sensor 30 indicates that the heel is floating from the base BS (step S30; YES), the arithmetic unit 100 returns the process to step S10. When the signal output from the heel sensor 30 indicates that the heel is not lifted from the base BS (step S30; NO), the arithmetic unit 100 advances the processing to step S40.

  (Step S40) The computing unit 100 counts (counts) the number of thigh joint plantar flexion motions. Specifically, the calculating part 100 adds 1 time to the frequency | count of a thigh joint floor bending motion. The calculation unit 100 outputs the counted number of times of thigh joint plantar flexion motion to the display unit 40 and the communication unit 50.

  (Step S50) The calculation unit 100 determines whether or not the count result of the number of thigh joint flexion movements has reached a specified number. Here, the prescribed number of times is determined by a doctor, a physical therapist, or the like according to the age of the patient, the postoperative recovery status, the elapsed time after the operation, and the like. When the count result of the number of thigh joint flexion movements has not reached the specified number (step S50; NO), the calculation unit 100 returns the processing to step S10 and continues counting the number of times. The calculation unit 100 ends the process when the count result of the number of times of the thigh joint plantar flexion movement reaches the specified number (step S50; YES).

Prior to the processing in step S10, the calculation unit 100 transmits patient-specific information such as the patient's name, injury / illness name, right / left foot, and automatic exercise load (for example, low load / high load) to the communication unit. 50 may be obtained. In this case, the calculation unit 100 stores these patient-specific information in the storage unit 110. The calculation unit 100 operates based on patient-specific information stored in the storage unit 110 until the patient using the thigh joint automatic exercise support device 1 is replaced with another patient.
Moreover, the calculating part 100 may acquire information, such as an implementation date and a patient's mood (feeling), via the communication part 50 prior to the process of step S10.

[Summary]
As described above, the thigh joint automatic movement support device 1 according to the first embodiment can detect the patient's automatic thigh joint flexion movement and count the number of movements. For this reason, according to the thigh joint automatic movement support device 1, it is possible to provide a game in which the content progresses according to the thigh joint sole flexion motion or according to the number of times of the motion. Such games include, for example, a game in which the thigh joint flexion motion is performed according to the timing displayed on the display unit 40, and a game in which characters in the game take a walk according to the number of thigh joint sole flexion motions. There is. As an example in this game, the display unit 40 displays an image such as a landmark for each reaching point corresponding to the number of thigh joint plantar flexion motions.
In addition, since the thigh joint automatic movement support device 1 includes the communication unit 50, the thigh joint bottom flexion motion detection result can be transmitted to the patient's smart phone or tablet. Thereby, according to the thigh joint automatic movement support device 1, the thigh joint sole bending motion can be used as means for operating a smart phone or a tablet. According to the thigh joint automatic movement support device 1 of this example, an operation of a game that operates on a smart phone or a tablet can be performed by a thigh joint floor bending operation.

The thigh joint automatic movement support device 1 determines the presence or absence of a thigh joint flexion operation on the basis of the determination condition that the heel is positioned at a predetermined position. Accordingly, in the thigh joint automatic movement support device 1, whether the operation of stepping on the foot switch FS by the calculation unit 100 detecting the lifting of the heel is due to the force applied to the calf region, It is possible to determine whether it is caused by putting power on. In other words, according to the thigh joint automatic exercise support device 1, it is possible to determine whether or not exercise effective for prevention of venous thrombosis of the lower limb is being performed.

Further, the thigh joint automatic movement support device 1 of the first embodiment includes a spring SPR.
By providing this spring SPR, the thigh joint automatic movement support device 1 can apply a load to the patient's calf. Accordingly, the thigh joint automatic movement support device 1 can improve the load of the thigh joint automatic movement as compared with the case where the spring SPR is not provided. In other words, the thigh joint automatic exercise support device 1 can improve the preventive effect of lower limb venous thrombosis as compared to the case where the spring SPR is not provided.
Moreover, in the thigh joint automatic movement support device 1 of the first embodiment, the heel positioning unit HH may be replaceable. The thigh joint automatic movement support device 1 can improve hygiene by making the heel positioning portion HH exchangeable for each patient. In addition, the thigh joint automatic movement support device 1 can match the shape of the heel positioning portion HH to the shape of the patient's foot by making the heel positioning portion HH exchangeable for each patient, and more accurately the heel position. Can be detected. The thigh joint automatic movement support device 1 can improve the fit between the heel and the heel positioning portion HH by matching the shape of the heel positioning portion HH with the shape of the patient's foot.

In this example, the arithmetic unit 100 determines that the lower extremity extension movement has been performed when the lower leg front LLF turns on the lower leg front contact sensor 20A after the patient's heel turns on the heel sensor 30. .
Hereinafter, a more specific operation of the calculation unit 100 will be described.

  (Step S110) The computing unit 100 acquires a signal output from the eyelid sensor 30. This signal indicates whether or not the heel is in contact with the heel sensor 30. When the signal output from the heel sensor 30 indicates that the heel is not in contact with the heel sensor 30 (step S110; NO), the arithmetic unit 100 returns the process to step S110. If the signal output from the heel sensor 30 indicates that the heel is in contact with the heel sensor 30 (step S110; YES), the arithmetic unit 100 advances the process to step S120.

(Step S120) The computing unit 100 acquires a signal output from the lower leg front contact sensor 20A. When the signal output from the crus front contact sensor 20A indicates that the crus front LLF is not in contact with the crus front contact sensor 20A (step S120; NO), the arithmetic unit 100 proceeds to step S120. return. When the signal output from the crus front contact sensor 20A indicates that the crus front LLF is in contact with the crus front contact sensor 20A (step S120; YES), the arithmetic unit 100 proceeds to step S140. Proceed.
That is, in step S110 and step S120, the calculation unit 100 determines that the detection results of the heel sensor 30 and the lower leg front contact sensor 20A are floated from the base BS from the state where the patient's foot is lowered to the base BS. In the case of indicating that the front contact sensor 20A is in contact with the front contact sensor 20A (that is, the position of the lower leg front LLF has changed), the number of lower extremity extension fist exercises is added.

  (Step S <b> 140) The computing unit 100 counts (counts) the number of times of lower limb extension and fistula movement. Specifically, the calculation unit 100 adds one time to the number of times of the lower extremity extension fist exercise. The calculation unit 100 outputs the counted number of lower extremity extension movements to the display unit 40 and the communication unit 50.

  (Step S150) The computing unit 100 determines whether or not the count result of the number of times of lower extremity extension fist exercise has reached the specified number. Here, the prescribed number of times is determined by a doctor, a physical therapist, or the like according to the age of the patient, the postoperative recovery status, the elapsed time after the operation, and the like. When the count result of the number of times of lower extremity extension fist exercise has not reached the specified number (step S150; NO), the arithmetic unit 100 returns the process to step S110 and continues counting the number of times. The calculation unit 100 ends the process when the count result of the number of times of the thigh joint plantar flexion movement reaches the specified number (step S150; YES).
