DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0026] like Figure 1-6 As shown, an arm fixing support of the utility model comprises a chassis 1, a lifting mechanism is provided at the center of the upper side of the chassis 1, a first disc 11 is fixedly mounted on the top of the lifting mechanism, a suction cup assembly is provided at the bottom of the first disc 11, a second disc 12 is rotatably mounted on the top of the first disc 11, a locking assembly is provided between the first disc 12 and the first disc 11, a connecting plate 13 is provided on the right side of the periphery of the second disc 12, a bearing plate 14 is provided on the right side of the connecting plate 13, and a clamping assembly is provided on the upper side of the bearing plate 14.

[0027] In the initial state, the chassis 1 is placed next to the patient's bed. The medical staff uses the suction cup assembly to absorb the chassis 1 on the ground to fix it, and then the chassis 1 is displaced. The lifting mechanism is adjusted to move up and down according to the height of the bed, and the locking assembly on the second disc 12 can be released. After the supporting plate 14 is placed on the bed, the angle of the supporting plate 14 is adjusted so that the patient's arm is placed on the supporting plate 14 at a comfortable angle. After the angle of the second turntable 12 is adjusted, the locking assembly is used to lock and fix the second disc 12. After the subsequent puncture of the patient is completed, the medical staff uses the clamping assembly to clamp the patient's arm. The clamping assembly can be suitable for clamping arms of different thicknesses. After clamping, the patient's hand is fixed, and there will be no unconscious shaking even when the patient is asleep, which will not affect the normal progress of hemodialysis.

[0028] The suction cup assembly includes a suction cup 15, which is fixedly installed at the bottom of the chassis 1. A first through hole is fixedly opened on the upper side of the suction cup 15, and a second through hole 16 matching the position of the first through hole is opened on the upper side of the chassis 1. A closing plug 17 is provided inside the second through hole 16, and a handle 18 is provided on the top of the closing plug 17.

[0029] In the initial state, the closing plug 17 completely closes the second through hole 16. When using the suction cup 15, the medical staff only needs to press down the base 1. The suction cup 15 is adsorbed on the ground to increase the stability of the base 1 and avoid sliding due to impact. When the suction cup 15 is subsequently released from adsorption, the medical staff pulls out the closing plug 17 through the handle 18, and external air enters the suction cup 15. The medical staff can easily release the adsorption state of the suction cup 15. After the release is completed, the closing plug 17 can be reinserted into the second through hole 16.

[0030] The lifting mechanism includes a sleeve 19, a sliding rod 20 is slidably mounted inside the sleeve 19, a first disc 11 is fixedly mounted on the top of the sliding rod 20, a plurality of connecting holes 21 are arranged up and down on the left side of the sliding rod 20, a first threaded hole is opened on the upper left side of the sleeve 19, a first threaded rod is threadedly connected inside the first threaded hole, one end of the first threaded rod close to the sliding rod 20 extends into one of the connecting holes 21, and a first screw handle 22 is fixedly mounted on the end of the first threaded rod away from the sliding rod 20.

[0031] In the initial state, one end of the first threaded rod extends into one of the connecting holes 21, and the position of the sliding rod 20 is fixed. The sliding rod 20 cannot move up and down. When the supporting height of the sliding rod 20 needs to be adjusted, the first handle 22 is turned to drive the first threaded rod to withdraw from the connection with the connecting hole 21, and then the sliding rod 20 can be adjusted to move up and down. After the adjustment is completed, the first threaded rod can be reconnected to one of the connecting holes 21.

[0032] A plurality of locking holes 23 are provided around the upper side of the first disc 11, and a connecting through hole is eccentrically provided on the upper side of the second disc 12. A second threaded rod 24 is threadedly connected inside the connecting through hole, and the lower end of the second threaded rod 24 extends into one of the locking holes 23. A second screw handle 26 is fixedly installed on the upper end of the second threaded rod 24.

[0033] In the initial state, the second threaded rod 24 locks the position of the second disk 11. When the rotation of the second disk 11 needs to be adjusted, the second threaded rod 24 is driven to rotate by the second handle 26 to withdraw it from the connection with the locking hole 23. After the second disk 11 has completed its rotation, the second threaded rod 24 is rotated again to align it with a locking hole 23 and connect it. The operation is simple and convenient.

[0034] The clamping assembly includes two clamping plates 27. An assembly groove is provided inside the bearing plate 14. An assembly block 28 is transversely installed at the center of the inner wall at the bottom of the assembly groove. Two moving blocks 29 are slidably installed inside the assembly groove. The assembly block 28 is located between the two moving blocks 29. An opening 30 is provided on the upper side of the bearing plate 14. A connecting block 31 slidably connected to the opening 30 is fixedly installed on the upper sides of the two moving blocks 29. The two clamping plates 27 are respectively fixedly installed on the upper sides of the two connecting blocks 31.

[0035] A plurality of first springs 32 are fixedly installed on the side where the two moving blocks 29 are close to each other, and a plurality of first springs 32 on the front and rear sides are fixedly connected to the assembly block 28 on the side where the two moving blocks 29 are close to each other. A slide groove 33 is provided on the upper side of the connecting plate 13, and a pulling block 34 is slidably installed inside the slide groove 33. A connecting rope 35 is fixedly installed on the side where the two moving blocks 29 are close to each other, and one end of the two connecting ropes 35 extends into the assembly block 28 and extends to the left of the bearing plate 14 and is fixedly connected to the pulling block 34.

[0036] A plurality of limiting holes 36 are arranged on the inner wall of the rear side of the assembly groove, a mounting groove is provided inside the pulling block 34, a top block 37 is slidably mounted inside the mounting groove, a limiting rod 38 is fixedly mounted on the rear side of the top block 37, one end of the limiting rod 38 extends into one of the limiting holes 36, a second spring 39 is fixedly mounted on the front side of the top block 37, one end of the second spring 39 is fixedly connected to the inner wall of the mounting groove;

[0037] A mounting block is disposed on the upper side of the top block 37 , a sliding opening connected to the mounting groove is provided on the upper side of the pulling block 34 , and a handle 40 is fixedly mounted on the upper side of the mounting block extending out of the sliding opening.

[0038] In the initial state, the elastic force generated by the plurality of first springs 32 on the front and rear sides will push the two splints 27 away from each other. When the patient is undergoing hemodialysis, the patient can place his arm on the supporting plate 14. After the puncture is completed, the medical staff holds the handle 40 and first drives the top block 27 forward to a certain extent. The top block 27 moves forward to compress the second spring 39 and drive the limiting rod 38 to withdraw from the connection with one of the limiting holes 36, and then moves the pulling block 34 to the left. The pulling block 34 synchronously drives the two splints 27 to move closer to each other through the two connecting ropes 35 until they touch the patient's arm to fix the patient's arm. After the fixation is completed, the medical staff can fix the position of the splint 27 by reconnecting the limit rod 38 with one of the limit holes 36. Since the lengths of the two connecting ropes 35 are constant and the position of the pulling block 34 is fixed by the limit rod 38, the two splints 27 cannot move away from each other. The medical staff can quickly complete the operation of fixing the patient's arm, and the fixing method is gentle to avoid causing harm to the patient. When releasing the fixation later, it is only necessary to release the connection between the limit rod 38 and the limit hole 36, and the first springs 32 will re-extend to automatically push the two splints 27 back to their original positions. The operation is convenient and quick.

[0039] Sponge pads 41 are fixedly mounted on the upper sides of the two splints 27 and the support plate 14 ; the provision of the sponge pads 41 makes the patient more comfortable when the two splints 27 and the support plate 14 are in contact with the patient.

[0040] According to the above overall description, the utility model can conveniently fix the patient's arm when in use, avoiding the patient's arm from shaking unconsciously due to factors such as falling asleep, which may affect the normal progress of hemodialysis, and can also reduce the occurrence of adverse events such as needle dislocation and hematoma at the puncture point. The operation process is simple and convenient, which can effectively improve the work efficiency of medical staff.
