Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0022] Please refer to Figures 1-4 The utility model discloses hemodialysis rehabilitation training holding ball, including holding ball structure 1 and small air pump 2, the inside of holding ball structure 1 is provided with embedded air bag 4 and air exchange structure 5, the form of embedded air bag 4 is oval air bag, and embedded air bag 4 is vertical placement, embedded air bag 4 is communicated with the outside through air exchange structure 5, air exchange structure 5 and small air pump 2 are communicated through inflation pipe 3.

[0023] The holding ball structure 1 includes a holding ball body 101, and the bottom end of the holding ball body 101 and the embedded air bag 4 are both provided with a through hole.

[0024] The air exchange structure 5 includes a communication pipe 501, the communication pipe 501 is located in the through hole of the holding ball body 101 and the embedded air bag 4, the bottom end of the communication pipe 501 is provided with a control valve 502, the outer side of the control valve 502 is provided with a valve body switch 503, and the control valve 502 is movably connected with the inflation pipe 3.

[0025] By setting the holding ball structure 1, the embedded air bag 4 and the air exchange structure 5, the small air pump 2 can be used to fill or extract gas into or out of the embedded air bag 4 through the inflation pipe 3, so that the embedded air bag 4 deforms in the holding ball body 101, the cavity volume between the embedded air bag 4 and the holding ball body 101 is adjusted, the deformability of the holding ball body 101 is adjusted, the patient can adjust the deformability of the holding ball body 101 according to the recovery condition, and the practicability of the holding ball is improved.

[0026] Specifically, the outer side of the holding ball body 101 is provided with an outer convex column 102, and the top end of the outer convex column 102 is provided with a contact convex point 103.

[0027] In the embodiment, the surface of the handgrip ball body 101 is formed with irregular contact points through the outward convex column 102 and the contact convex point 103, so that the palm of the patient can be massaged when holding the handgrip ball body 101, thereby improving the hand recovery effect.

[0028] Specifically, the handgrip ball body 101 and the inner part of the embedded air bag 4 through hole are both provided with sealing washers 504, and the outer wall of the communication pipe 501 is in contact with the inner part of the sealing washer 504.

[0029] In the embodiment, the sealing washer 504 can prevent the communication pipe 501 from leaking gas when penetrating the handgrip ball body 101 and the embedded air bag 4.

[0030] Specifically, a lifting structure 6 is arranged between the handgrip ball body 101 and the embedded air bag 4, the lifting structure 6 includes a telescopic sleeve rod 601, both ends of the telescopic sleeve rod 601 are connected with the handgrip ball body 101 and the embedded air bag 4 respectively, and the surface of the telescopic sleeve rod 601 is provided with a damping spring 602.

[0031] In the embodiment, the telescopic sleeve rod 601 and the damping spring 602 have automatic rebounding property, which can reduce the forming degree of the bottom connection between the handgrip ball body 101 and the embedded air bag 4, so that the communication pipe 501 can be protected from being damaged by the forming of the handgrip ball body 101 and the embedded air bag 4 when the communication pipe 501 is located at the bottom of the handgrip ball body 101 and the embedded air bag 4.

[0032] In use, the patient can contact the palm and fingers with the handgrip ball body 101, and then perform the operation of kneading the handgrip ball body 101 by making a gripping gesture with the palm and fingers, thereby completing the strength recovery training of the hand.

[0033] When it is needed to increase the deformation difficulty of the handgrip ball body 101, that is, a greater gripping force is needed to make the handgrip ball body 101 deform, the inflation pipe 3 and the control valve 502 are connected with each other, then the control valve 502 is opened through the valve body switch 503, and then the small air pump 2 is started, so that the small air pump 2 fills the air in the embedded air bag 4 through the inflation pipe 3 and the communication pipe 501, so that the volume of the embedded air bag 4 gradually expands, and the volume of the cavity formed between the embedded air bag 4 and the handgrip ball body 101 gradually decreases.

[0034] So that the patient at this time in kneading the grip ball body 101, will make the grip ball body 101 easily contact with the embedded air bag 4, because the embedded air bag 4 at this time is in the inflation state, resulting in the embedded air bag 4 itself has a certain hardness, resulting in the patient in kneading the grip ball body 101 in the process will be hindered by the embedded air bag 4 in the inflation state, make the deformation difficulty of the grip ball body 101 increase, so that the patient needs to use a larger holding force to make the grip ball body 101 deformation;

[0035] When it is necessary to reduce the deformation difficulty of the grip ball body 101, that is, a smaller holding force is required to make the grip ball body 101 deformation, the inflation pipe 3 and the control valve 502 can be connected with each other, then the control valve 502 is opened through the valve body switch 503, and then the small air pump 2 is started, so that the small air pump 2 extracts the gas in the embedded air bag 4 through the inflation pipe 3 and the communication pipe 501, so that the volume of the embedded air bag 4 gradually decreases, so that the volume of the cavity formed between the embedded air bag 4 and the grip ball body 101 gradually increases;

[0036] So that the patient at this time in kneading the grip ball body 101, will promote the grip ball body 101 to deform to a larger extent before contacting the embedded air bag 4, so that the deformation difficulty of the grip ball body 101 is reduced, so that the patient needs to use a smaller holding force to make the grip ball body 101 deformation;

[0037] The above working principle can refer to the structure of the existing technology "grip strengthener", and the difficulty of bending the grip strengthener is realized by adjusting the spring force in the grip strengthener.

[0038] In summary, the hemodialysis rehabilitation training grip ball is provided with the holding ball structure 1, the embedded air bag 4 and the air exchange structure 5, the air exchange structure 5 can promote the small air pump 2 to fill or extract the gas in the embedded air bag 4 through the inflation pipe 3, so that the embedded air bag 4 deforms in the grip ball body 101, the volume of the cavity between the embedded air bag 4 and the grip ball body 101 is adjusted, the deformable degree of the grip ball body 101 is adjusted, the patient can adjust the deformable degree of the grip ball body 101 according to the recovery condition, and the practicability of the grip ball is improved.

[0039] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
