Description

Technical Field

[0001] The present invention particularly relates to a fistula training device. Background Art

[0002] Arteriovenous fistula is the lifeline of dialysis patients. Performing fistula exercises after fistula surgery can promote the maturation of the arteriovenous fistula, reduce the occurrence of arteriovenous fistula complications, and prolong the service life of the arteriovenous fistula.

[0003] Internal fistula exercises are divided into three stages: fingertip exercises, wrist exercises, and arm-binding and fist-clenching exercises.

[0004] Among them, the arm-binding and fist-clenching exercise requires both hands to be performed at the same time. During training, the trainee extends the arm to be trained forward in parallel, then holds the upper arm of this arm with the other hand, and then makes fists with both hands at the same time, 10-20 times a day, each time for at least 3 minutes.

[0005] During the fistula exercise, one arm needs to be kept flat throughout the whole process, and both hands need to be clenched into fists at the same time. In addition, a single training session lasts at least 3 minutes. Therefore, some patients are unable to persist in the training process, which leads to failure to achieve the final training effect.

DETAILED DESCRIPTION

[0031] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0032] See also Figures 1 to 3 The present invention provides an internal fistula training device, comprising a lifting support frame 100, a support plate 200 and a clamping mechanism 300. The lifting support frame 100 is used to support the support plate 200, and the support plate 200 is used to support the forearm. The clamping mechanism 300 is used to drive the hand to make a fist or clamp the upper arm.

[0033] Specifically, the height of the lifting support frame 100 can be adjusted. The lifting can be adjusted to meet the needs of patients of different heights. The specific lifting structure of the lifting support frame 100 adopts the form of a lifting motor plus a support rod, and can also adopt a structure of a fixed support sleeve, an insertion rod, and a locking member. By moving the insertion rod up and down and locking it with a locking member, different heights can be adjusted.

[0034] The support plate 200 can be detachably arranged on the top of the lifting support frame 100, and can be used to support the forearm. When in use, the height of the lifting support frame 100 is adjusted first, and then the forearm is placed on the support plate 200 in a horizontal state. In specific implementation, a heating component and a massage component can be arranged in the support plate 200, and the arm can be heated and massaged for physiotherapy.

[0035] There are two groups of clamping mechanisms 300, and the two groups of clamping mechanisms 300 are respectively arranged at both ends of the support plate 200. One of the clamping mechanisms 300 is arranged opposite to the hand, and the other clamping mechanism 300 is arranged opposite to the upper arm. The clamping mechanism 300 includes a clamping drive member 310, a first mounting plate 320 and a clamp 330. The first mounting plate 320 is arranged on the support plate 200. There are five clamps 330, and the five clamps 330 are arranged at intervals on the first mounting plate 320. The clamping drive member 310 is connected to the five clamps 330, and can drive the free ends of the five clamps 330 to bend inward in a gap-like manner to form a fist state or be loosened.

[0036] When in use, the arm is first placed on the support plate 200, and the hand is placed on the clamping mechanism 300 at the front of the support plate 200, the upper arm is aligned with another clamping mechanism 300, and then the clamping drive 310 is started to drive the gaps between the five clamps 330 to bend inward to make a fist or release. When making a fist, the clamps 330 at the front drive the five fingers to make a fist, and the five clamps 330 at the rear are clamped on the upper arm and then released. Repeating the training many times can complete the arm binding and fisting exercise, thereby promoting the maturation of the arteriovenous fistula, reducing the occurrence of complications of the arteriovenous fistula, and thus prolonging the service life of the arteriovenous fistula.

[0037] In a specific implementation, a plurality of finger sleeves may be arranged at intervals on the clamp 330 of the clamping mechanism 300 corresponding to the hand, and the finger sleeves are used to be sleeved on the fingers. When in use, the finger sleeves are tightly worn on the corresponding fingers, and the fingers are driven to move synchronously during the bending and flattening process of the clamp 330.

[0038] In this embodiment, the clamp 330 includes a plurality of clamping blocks 331 and a connecting piece 332. The plurality of clamping blocks 331 are hinged and connected in a straight line by a hinge, and the hinge is located near the inner side, and every two adjacent clamping blocks 331 are connected in a straight line by a connecting piece 332 near the outer side. The clamping drive member 310 includes a separation drive source 311 and a separation piece 312. A separation piece 312 is arranged between the tops of every two adjacent clamping blocks 331. The separation drive source 311 is arranged on the support plate 200 and is connected to all the separation pieces 312, and can drive all the separation pieces 312 to extend to both sides and separate the tops of two adjacent clamping blocks 331 so that the clamping blocks 331 connected thereto rotate outward.

[0039] In the normal state, the clamp 330 is in a straight line under the action of the hinge and the connecting piece 332. When the driving source 311 and the separating piece 312 are extended to both sides to separate the tops of the two clamping blocks 331, the bottoms of the clamping blocks 331 are hinged to each other, so that the clamping blocks 331 can rotate inward. When all the separating pieces 312 extend outward at the same time, the entire clamp 330 can be in a fisting motion, thereby driving the fingers to make a fist or clench the upper arm.

[0040] In this embodiment, the connecting member 332 includes two magnetic members with opposite magnetic properties, and the two magnetic members with opposite magnetic properties are respectively arranged at the ends of two adjacent clamping blocks 331 that are close to each other. Of course, in other embodiments, the connecting member 332 can also be other forms, such as an elastic connecting member 332. In addition, the connecting member 332 can also be replaced by a torsion spring on the hinge, which can also achieve the connection, closeness or separation of the upper ends of the clamping blocks 331.

[0041] In the present embodiment, the separation member 312 includes an elastic bag, and the elastic bag is connected between two adjacent clamping blocks 331. The separation driving source 311 is an inflatable device, and all the elastic bags are connected to the inflatable device through an air pipe. When in use, the elastic bag is filled with gas through the inflatable device, which can drive the elastic bag to expand, thereby driving the outer sides of the two clamping blocks to separate. When the gas in the elastic bag is released, the position of the clamping block 331 is restored under the action of the connecting member 332. It should be noted that the elastic bag can also be filled with liquid, and the inflatable device can be used as a buffer water pump to achieve the same effect. In addition, in the specific implementation, the inflatable device can use an inflatable device with a pressure sensor. During the inflation process, the pressure can be set. When it is detected that the pressure reaches the preset value, the inflation can be stopped to prevent excessive inflation. In addition, the air pipes of the two groups of clamping mechanisms 300 can be connected to the inflation device through two solenoid valves respectively. Each group of clamping mechanisms 300 corresponds to a pressure sensor. The two pressure sensors and solenoid valves separately control the expansion of the elastic bags of the two clamping mechanisms 300, thereby controlling the bending condition and the gripping strength.

[0042] As a preferred embodiment, the device also includes a sliding component 400, and a sliding groove 210 is arranged on the support plate 200 along the length direction. The sliding component 400 can slide and engage with the sliding groove 210, and can slide along the sliding groove 210, and the clamping mechanism 300 arranged corresponding to the upper arm is arranged on the sliding component 400.

[0043] The position of the rear end clamping mechanism 300 can be adjusted by the sliding assembly 400 to facilitate use by patients with different arm lengths.

[0044] As a more preferred embodiment, the device further comprises a frequency regulating mechanism 500, which is arranged on the trachea and is used to regulate the frequency of inflation and deflation of the elastic bag.

[0045] Specifically, the frequency adjustment mechanism 500 includes a three-way joint 510, a pipe cover 520 and a rotating power source 530. The inflation device and the air pipe are respectively connected to the two ends of the three-way joint 510. The side wall of the third end of the three-way joint 510 is provided with a first air outlet. The sealed and rotatable cover of the pipe cover 520 is provided on the third end of the three-way joint 510. The side wall of the pipe cover 520 is provided with a second air outlet. The rotating power source 530 is connected to the pipe cover 520 and can drive the pipe cover 520 to rotate. During the rotation of the pipe cover 520, the second air outlet can be aligned with and connected to the first air outlet.

[0046] During use, when it is necessary to inlet air into the elastic bag, the pipe cover 520 is rotated so that the first air outlet and the second air outlet are in a dislocated and disconnected state, and the gas enters the elastic bag through the three-way joint 510. When it is necessary to release the gas, the pipe cover 520 is rotated by rotating the power source 530 so that the first air outlet and the second air outlet are in a connected state, and the elastic bag can be closed. During use, the frequency of deflation and intake of the elastic bag is controlled by controlling the rotation speed of the pipe cover 520, so as to adjust the frequency of clenching or loosening the fist. In the early stage of training, the frequency can be kept low, and as the training time increases, the frequency can be increased.

[0047] In this embodiment, the rotation power source 530 includes a handle, which is disposed on the pipe cover 520 and extends radially along the pipe cover 520. When in use, the handle is rotated by the other hand to complete the deflation and inflation actions, and the deflation and inflation frequency is adjusted by the rotation speed.

[0048] Methods of using the above-mentioned fistula training device:

[0049] When in use, first adjust the height of the lifting support frame 100 according to the body height or sitting height, then place the forearm on the support plate 200, and align the hand with the front clamping mechanism 300, then put the finger sleeve on the corresponding clamp 330 on the finger, then start the inflation device to inflate the elastic bag, and at the same time, continue to rotate the tube cover 520 to drive the gap between the clamps 330 to make a fist, so that the front clamp 330 can drive the five fingers to make a fist, and the five clamps 330 at the rear end are clamped on the upper arm and then released. Repeated training can complete the arm-binding fisting exercise, thereby promoting the maturation of the arteriovenous fistula, reducing the occurrence of complications of the arteriovenous fistula, and thus prolonging the service life of the arteriovenous fistula.
