Description

Technical Field

[0001] The present invention relates to the technical field of training devices, and particularly to a training device for improving the ability of cold-induced vasodilation. Background Art

[0002] Cold-induced vasodilation means that when the body is acutely exposed to a cold environment, the blood flow in the extremities, such as fingers, toes, etc., will be rapidly and dynamically adjusted according to the exposed cold environment and the body's thermal state. As the temperature of the exposed environment drops, the skin temperature of the body initially drops sharply, but soon fluctuates within a certain range. The phenomenon of cold-induced vasodilation is the key to maintaining the integrity of local tissues and reducing the risk of cold injury, and is considered a protective mechanism against cold injury of the extremities.

[0003] By locally repeatedly cooling and stimulating to cause the phenomenon of cold-induced vasodilation, the body's ability to respond to cold stimuli can be changed.

[0043] See Figures 1 to 9 , this embodiment provides a training device for improving the cold-induced vasodilation ability, including a support base 10, a temperature detection mechanism 20, a refrigeration device 30, and a controller (not shown).

[0044] The support base 10 is used to support the palm. The trainee places the palm on the support base 10 with the nail roots of the fingers facing upwards. The temperature detection mechanism 20 is arranged on the support base 10 and is used to detect the temperature at the nail roots of the nails placed on the support base 10. Specifically, the temperature detection mechanism 20 mainly detects the temperature of the nail roots at a position about 2 mm away from the nail bed on the fingers, and the temperature at this place can more accurately represent the temperature of the blood in the upper limb blood vessels. The refrigeration device 30 is used to cool the inner side of the upper arm. Specifically, the refrigeration device 30 mainly cools the blood in the middle artery blood vessels of the upper arm. The controller is electrically connected to the temperature detection mechanism 20 and the temperature control mechanism respectively. The controller can control the refrigeration device 30 according to the temperature feedback by the temperature detection mechanism 20 to realize the temperature gradient management of the blood in the blood vessels in the upper arm in multiple time periods. Specifically, according to the temperature feedback from the temperature detection mechanism 20 to the controller, the controller controls the refrigeration device 30 to control the temperature of the blood in the artery blood vessels in the upper arm. When the blood in the artery blood vessels is transported to the palm, it can present a fixed temperature in one training time period and another temperature in the next training time period, so that the temperature of the cooled blood is controllable in different training time periods. Among them, the refrigeration device 30 and the controller can both adopt existing technologies. By using the refrigeration device 30 to gradually cool the blood in the artery blood vessels from the upper arm, the intensity of the cold stimulation can be gradually adjusted, and the subjective cold discomfort of the trainee is relatively light. Compared with the direct cold water immersion method, this method is more easily accepted by them.

[0045] In this embodiment, under the control of the controller, the temperature detection mechanism 20 detects and feeds back the blood temperature in the palm at the nail roots of the nails, and then according to this temperature, the refrigeration device 30 is used to cool the blood in the artery blood vessels in the upper arm in real time. The blood vessels in the palm are stimulated by the blood at different temperatures in different time periods to cause the cold-induced vasodilation phenomenon, so that when the trainee enters a cold environment subsequently, the hand operation flexibility can be maintained and the local cold tolerance can be improved.

[0046] In one embodiment, the training device further includes an inner support rod 40.

[0047] One end of the inner support rod 40 is rotatably connected to one end of the support base 10. Specifically, the end of the inner support rod 40 away from the support base 10 can be lifted. The refrigeration device 30 is fixedly connected to the end of the inner support rod 40 away from the support base 10. The refrigeration device 30 can extend along the forearm into the upper arm and fit with the upper arm along with the inner support rod 40.

[0048] In this embodiment, when using this training device, the refrigeration device 30 is connected and inserted into the sleeve opening through the inner support rod 40, and can extend to the upper arm. Then, the refrigeration device 30 is attached to the inner side of the upper arm to cool the blood in the arterial blood vessels in the upper arm. The refrigeration device 30 is built into the clothes, which can avoid the inconvenience caused by taking off clothes during training and also avoid the discomfort of the arms caused by taking off clothes during winter training. In addition, when the training device is fixed on the desktop, during use, the height of the trainee's shoulders is higher than the desktop. The inner support rod 40 supports the refrigeration device 30. During the process of the refrigeration device 30 extending from the clothes cuff to the inner side of the upper arm, the inner support rod 40 can rotate on the support base 10, so that the trainee does not need to adjust the posture significantly. The end of the inner support rod 40 and the refrigeration device 30 can extend obliquely upward to the inner side of the upper arm, which conforms to ergonomics, making the trainee more comfortable during training and reducing the fatigue during use.

[0049] In one embodiment, the support base 10 includes a base body 11 and a first mounting block 12 connected to the end of the base body 11.

[0050] The training device further includes a second mounting block 50, an arc-shaped mounting block 51, an arc-shaped connecting block 52, an arc-shaped support plate 53, and a locking assembly 54.

[0051] The second mounting block 50 is rotatably connected to the upper end of the first mounting block 12. The second mounting block 50 is arranged side by side with the first mounting block 12, and the lower end of the second mounting block 50 can abut against the lower end of the first mounting block 12. The arc-shaped mounting block 51 is fixedly connected to the side of the second mounting block 50 facing away from the first mounting block 12, and the arc-shaped mounting block 51 has an upward opening. The arc-shaped connecting block 52 is slidably arranged on the arc-shaped mounting block 51, and the sliding track of the arc-shaped connecting block 52 coincides with the length direction of the arc-shaped mounting block 51. Specifically, grooves are respectively formed on the inner and outer sides of the arc-shaped mounting block 51, and a corresponding connecting groove (arc-shaped) is also formed on the side of the arc-shaped connecting block 52 facing the second mounting block 50. One end of the arc-shaped mounting block 51 away from the second mounting block 50 is located in the connecting groove, and the mouth of the connecting groove is inwardly converged and slidably engaged with the grooves on the inner and outer sides of the arc-shaped mounting block 51, which enables the arc-shaped connecting block 52 to rotate on the second mounting block 50.

[0052] One end of the arc-shaped support plate 53 is fixedly connected to the side of the arc-shaped connecting block 52 facing away from the second mounting block 50. The locking assembly 54 is used to keep the first mounting block 12 and the second mounting block 50 relatively stationary. The end of the inner support rod 40 away from the refrigeration device 30 is connected to the end of the arc-shaped connecting block 52 facing away from the second mounting block 50.

[0053] In this embodiment, when the inner support rod 40 is in a horizontal state, the first mounting block 12 and the second mounting block 50 are arranged side by side. As the second mounting block 50 rotates relative to the first mounting block 12, the end of the inner support rod 40 away from the second mounting block 50 is lifted (to conform to the attitude of the inner support rod 40 when the trainee inserts the end of the inner support rod 40 into the cuff). At this time, the trainee sits in front of the table, with the palm extended downward. The refrigeration device 30 at the end of the inner support rod 40 is located below the upper arm (not the inner side of the upper arm). Then, the arc-shaped connecting block 52 is rotated to rotate the arc-shaped support plate 53 under the forearm and the upper arm. At this time, the refrigeration device 30 at the end of the inner support rod 40 rotates to the inner side of the upper arm. Then, the locking assembly 54 locks the second mounting block 50 and the first mounting block 12. The arc-shaped support plate 53 is in an inclined state, forming a support for the forearm and the upper arm, so that the trainee can reduce fatigue during training, which conforms to ergonomics.

[0054] In one embodiment, a limiting groove 501 is formed on the surface of the second mounting block 50 facing away from the first mounting block 12, and the limiting groove 501 is located below the arc-shaped mounting block 51.

[0055] The locking assembly 54 includes an arc-shaped locking block 541, a sliding rod 543, a slider 544, a locking tooth 545, a first rack 546 and a second rack 547.

[0056] The arc-shaped locking block 541 is connected to the lower end of the first mounting block 12, and its center of the circle is located on the rotation center line of the second mounting block 50. A plurality of locking grooves 542 extending along the rotation center line direction of the second mounting block 50 are formed on the inner side of the arc-shaped locking block 541. The two ends of the sliding rod 543 are respectively connected to the two opposite side walls of the limiting groove 501, and the sliding rod 543 extends along the rotation center line direction of the second mounting block 50. The slider 544 is slidably sleeved on the sliding rod 543 through an opening, and its lower end surface is an arc surface. The slider 544 can slide on the sliding rod 543, and the sliding direction of the slider 544 is the same as the rotation center line direction of the second mounting block 50.

[0057] More than one locking tooth 545 is provided. The locking block is fixedly connected to the lower end surface of the slider 544. The locking block is located on the side surface of the arc-shaped locking block 541 and can enter the corresponding locking groove 542 after moving with the slider 544. The first rack 546 is connected to the upper end of the slider 544 and is laid along the rotation center line direction of the second mounting block 50. The second rack 547 is fixedly connected to the outer ring of the arc-shaped connecting block 52 and meshes with the first rack 546.

[0058] In this embodiment, after the inner support rod 40 is inserted from the cuff, move the palm closer to the support base 10 so that the inner support rod 40 moves along the forearm and finally reaches the upper arm. At this time, the second mounting block 50 rotates a certain angle relative to the first mounting block 12, and then the arc-shaped support plate 53 is rotated, and the arc-shaped support plate 53 is rotated under the arm for support. At the same time, the rotation of the arc-shaped support plate 53 drives the arc-shaped connecting block 52 to rotate, and then drives the first rack 546 to move through the second rack 547. The first rack 546 drives the slider 544 to horizontally traverse. At this time, the locking tooth 545 under one end of the slider 544 is inserted into the locking groove 542 from the side, so that the second mounting block 50 is stationary relative to the first mounting block 12 to complete the locking, and then the arc-shaped support plate 53 is always in an inclined state. The palm is placed on the support base 10, and the wrist is located above the junction of the first mounting block 12 and the second mounting block 50. The arc-shaped support plate 53 supports the arm. In addition, since the slider 544 can only move horizontally in the limit groove 501, the arc-shaped connecting block 52 can only rotate at a certain angle on the arc-shaped mounting block 51, so that the arc-shaped connecting block 52 will not be separated from the arc-shaped mounting block 51.

[0059] In one embodiment, the inner support rod 40 is rotatably connected to the arc-shaped connecting block 52, which enables the cooling device 30 at the end of the inner support rod 40 away from the second mounting block 50 to effectively fit when facing the upper arms of different thicknesses of different trainees. In addition, the outer layer of the cooling device 30 can be set as a sac-like shape with variable volume, so as to make the cooling device 30 fit more closely to the inner side of the upper arm. The cooling device 30 can also be pressurized to fit more closely to the upper arm and have a better cooling effect.

[0060] In one embodiment, a support rod support plate 60 extending in the horizontal direction is connected to the end of the arc-shaped locking block 541 away from the first mounting block 12; the support rod support plate 60 can support the inner support rod 40.

[0061] In one embodiment, a magic tape that can surround the arm for one week is provided at the end of the arc-shaped support plate 53 away from the arc-shaped connecting block 52. One end of the magic tape is connected to the arc-shaped support plate 53, and the other end of the magic tape can be adhered to itself after surrounding the arm for one week. When the cooling device 30 fits to the inner side of the upper arm, the arc-shaped support plate 53 is located under the upper arm to support it. At this time, the cooling device 30, the arm and the arc-shaped support plate 53 are tied together by the magic tape surrounding the upper arm for one week, so that the cooling device 30 fits closely to the inner side of the upper arm.

[0062] In one embodiment, the inner support rod 40 includes an outer tube body 41 and an inner rod body 42. The inner rod body 42 is rotatably connected to the arc-shaped connecting block 52. One end of the inner rod body 42 away from the arc-shaped connecting block 52 is slidably inserted into the outer tube body 41 and cannot be detached. Specifically, a limiting cylinder with a larger size is connected to one end of the inner rod body 42 located inside the outer tube body 41, and the mouth of the outer tube body 41 contracts inward to form a limiting ring. The limiting cylinder can abut against the limiting ring, so that the inner rod body 42 and the outer tube body 41 will not be detached, and the inner circle of the limiting ring is slidably matched with the inner rod body 42. The arc-shaped support plate 53 includes an outer plate body 531 and an inner plate body 532. An installation hole is provided on the outer plate body 531 along its length direction. One end of the inner plate body 532 is fixedly connected to the arc-shaped connecting block 52, and the end of the inner plate body 532 away from the arc-shaped connecting block 52 is slidably inserted into the installation hole and cannot be detached. The non-detachable setting of the outer plate body 531 and the inner plate body 532 can refer to the setting method of the inner rod body 42 and the outer tube body 41.

[0063] The training device further includes a mounting bracket 70, a rotating member 71 and an elastic member 72.

[0064] The mounting bracket 70 is used to be mounted on the desktop. The rotating member 71 is rotatably arranged on the mounting bracket 70, and the rotating member 71 is located below the arc-shaped support plate 53. One end of the elastic member 72 is fixedly connected to the rotating member 71, and the other end of the elastic member 72 is fixedly connected to the outer plate body 531 and the outer tube body 41 respectively. Specifically, the rotating member 71 can be a semi-circular block. A dovetail block is connected to the outer periphery of the rotating member 71. The upper end of the rotating member 71 is connected to the elastic member 72. A semi-circular notch is provided on the mounting bracket 70. The rotating member 71 can be placed in the semi-circular notch, and the inner wall of the semi-circular notch is arc-shaped and a dovetail groove slidably matched with the dovetail block is provided on the arc surface, which enables the rotating member 71 to rotate in the semi-circular notch. In addition, the rotating member 71 can also be a sphere and is connected to the mounting bracket 70 by a spherical pair, and the elastic member 72 can be elastic rubber.

[0065] In this embodiment, the trainee can place the palm on the desktop and the arm is naturally bent. At this time, the palm is closer to oneself and can be seen more clearly. The temperature detection mechanism 20 can be aligned with the root of the nail, and the accuracy is relatively high at this time.

[0066] Then, the refrigeration device 30 is put in from the cuff. The arm moves forward, and the palm presses on the support seat 10. Then, the support seat 10 is pushed to continue moving horizontally and rotate at the same time, so that the entire bent arm is straightened. At this time, the outer tube body 41 of the inner support rod 40 and the outer plate body 531 of the arc-shaped support plate 53 are pulled by the elastic member 72 and cannot move forward with the support seat 10. This enables the refrigeration device 30 at the end of the inner support rod 40 to move forward along the straightened arm to below the upper arm. During the whole process, the arm is naturally stretched, which conforms to ergonomics.

[0067] Finally, rotate the arc-shaped support plate 53 and place it under the arm to form a support for training.

[0068] In one embodiment, the training device further includes a sliding mounting block 73, a rotary block 74, a retaining ring 75, a strip-shaped limiting block 76, a guide rod 77, and a first spring 78.

[0069] The sliding mounting block 73 is horizontally slidably arranged on the mounting frame 70. The rotary block 74 is rotatably arranged on the sliding mounting block 73, and a through hole 741 is formed in it along the horizontal direction. The retaining ring 75 is connected to the upper inner wall of the mounting hole. One end of the strip-shaped limiting block 76 is slidably arranged in the through hole 741, and the other end is fixedly connected to the lower end of the seat body 11. A through groove is formed in the upper end of the strip-shaped limiting block 76 along its length direction. Both ends of the guide rod 77 are connected to the inner walls on both sides of the through groove, and the guide rod 77 slidably passes through the retaining ring 75. The first spring 78 is sleeved outside the guide rod 77. One end of the first spring 78 abuts against the inner wall of the through groove, and the other end abuts against the retaining ring 75. The retaining ring 75 is located between the end of the strip-shaped limiting block 76 connected to the support seat 10 and the first spring 78. In addition, the upper end surface of the seat body 11 of the support seat 10 is covered with a material with high friction, such as rubber, so that when the palm is placed on it, it can be smoothly pushed without relative slippage between the palm and the seat body 11.

[0070] In this embodiment, when the palm is placed on the seat body 11 of the support seat 10 and the seat body 11 is pushed to slide, at this time, the sliding mounting block 73 slides on the mounting frame 70. When the refrigeration device 30 reaches the elbow, when the palm moves forward, it rotates by the way. At this time, the rotary block 74 rotates on the sliding mounting block 73, so that the arm is straightened and the refrigeration device 30 can move to the upper arm. Since the strip-shaped limiting block 76 can slide in the through hole 741, the seat body 11 of the support seat 10 can slide relative to the rotary block 74 to a certain extent, and the speed of the trainee's arm from bending to straightening is faster, thereby reducing the discomfort caused by the refrigeration device 30 at the elbow abutting against the upper arm.

[0071] In addition, a stop block 79 is further arranged on the sliding mounting block 73, and the stop block 79 abuts against the end of the strip-shaped limiting block 76, so that the strip-shaped limiting block 76 cannot slide out of the through hole 741 until the rotary block 74 rotates by an angle and the strip-shaped limiting block 76 is misaligned with the stop block 79. At this time, the strip-shaped limiting block 76 can slide out of the through hole 741. The stop block 79 enables the trainee to independently control whether the support seat 10 needs to rotate relatively or slide obliquely. This depends on the trainee's height, arm length, etc., so as to meet the needs of different trainee groups, so that different trainees can adaptively move according to their own situations when the refrigeration device 30 reaches the elbow, so that the arm can be straightened, which conforms to ergonomics.

[0072] In one embodiment, the temperature detection mechanism 20 includes a detection frame 21, an isolation block 22, and a probe temperature sensor 23.

[0073] The detection frame 21 is slidably arranged on the seat body 11 and can slide close to or away from the position of the fingernail root on the seat body 11, and the detection frame 21 can be kept stationary on the seat body 11. The isolation block 22 has a vacuum inner cavity and is slidably arranged on the detection frame 21 in the vertical direction and is subjected to a downward elastic force. The probe temperature sensor 23 is rod-shaped, the upper end of the temperature sensor 23 is inserted into the vacuum inner cavity of the isolation block 22, and the lower end of the probe temperature sensor 23 is used to detect the temperature at the nail root.

[0074] Specifically, two mating holes 13 are formed on one side of the seat body 11, and the detection frame 21 has two insertion rods 24 that can be slidably inserted into the mating holes 13. The detection frame 21 also has a cross beam 25, and the cross beam 25 is fixedly connected to the two pins through a connecting member. Two vertically penetrating holes are formed on the cross beam 25. The lower end of the isolation block 22 slidably passes through a through hole on the cross beam 25, a handle 26 is connected to the upper end of the isolation block 22, a second spring 27 is connected to the lower end of the handle 26, and the second spring 27 is fixedly connected to the upper end surface of the cross beam 25. The other end of the handle 26 away from the isolation block 22 is connected to a vertical block 28. The lower end of the vertical block 28 passes through the other through hole on the cross beam 25 and then hangs in the air. One or more insertion pieces 29 are arranged at the lower end of the vertical block 28, and the insertion pieces 29 are slidably arranged at the lower end of the vertical block 28 and cannot be separated. A row of heat dissipation grooves 14 are formed on the seat body 11 in parallel, and the insertion pieces 29 can be inserted into the corresponding heat dissipation grooves 14.

[0075] In this embodiment, placing the finger at the heat dissipation groove 14 can avoid heat accumulation under the finger and affect the accuracy of the detection by the temperature sensor 23. In addition, the rod-shaped temperature sensor 23 has strong durability, but its outer wall can conduct heat, and the temperature in the surrounding air is transmitted to its lower end through its rod-shaped outer wall, affecting its detection accuracy. By setting a vacuum environment in the isolation block 22 and placing most of the temperature sensor 23 in the vacuum, heat transfer is avoided, so that only the lower end head of the temperature sensor 23 detects the temperature at the fingernail root, and the detection accuracy is higher.

[0076] During operation, lift the handle 26 to stretch the second spring 27, the insertion piece 29 leaves the heat dissipation groove 14, and the detection frame 21 slides until the temperature sensor 23 is located above the nail root, and then release the handle 26, and the insertion piece 29 is inserted into the corresponding heat dissipation groove 14, so that the detection frame 21 cannot slide horizontally. At this time, the head of the temperature sensor 23 only abuts against the fingernail root, and temperature detection can be realized, and fingers of different sizes of different trainees can be accommodated.
