[0016] The principle and beneficial effects of this technical solution:

[0017] (1) The fixing assembly and the protective assembly provided in the present invention can fix the position of the patient's arm to a certain extent, and at the same time can prevent the patient's limb movement from squeezing the dialysis tube. After the patient undergoes dialysis puncture, the patient's arm needs to be placed at the top of the side groove so that the patient's upper arm contacts the connecting seat and the upper surface of the first support plate. The distance between the first support plate and the connecting seat is adjusted according to the length of the patient's forearm. The rotating plate is rotated, and the rotating rod coaxially connected to the rotating plate will drive the second bevel gear coaxially connected to its other end to rotate, so that the first bevel gear meshing with the second bevel gear rotates. At this time, the screw coaxially connected to the first bevel gear will cause the first support plate to move along the screw axis. At this time, the first support plate will move along the plug rods on both sides of the connecting seat until the position where the arc grooves are opened on the first support plate and the second support plate moves to the patient's elbow joint. At this time, the patient's forearm is placed on the second support plate, so that the patient's forearm is in contact with the groove opened on the second support plate, and then the protective cover set by the fixing block of the protective assembly is rotated to a horizontal position.

[0018] (2) The positioning assembly provided in the present invention can further fix the patient's arm. The position of the slider is adjusted according to the puncture position of the patient's arm, so that the pressure plate connected to the bottom end of the telescopic rod is misaligned with the dialysis tube, and then the telescopic rod at the bottom end of the slider is extended so that the pressure pad at the bottom end of the pressure plate can press the patient's arm.

[0019] (3) The massage assembly and ventilation groove provided in the present invention can improve the comfort of patients during long-term dialysis. When the patient feels that the surrounding environment is hot, the hydraulic rod can be driven to extend and retract, so that the hydraulic rod drives the sliding plate to move. The folding pad connected to one side of the sliding plate will change the shielding area of ​​the ventilation groove, thereby adjusting the ventilation degree of the ventilation groove to help the patient cool down.

The free end of the rotating rod 31 is coaxially connected to a rotating plate 32.

[0031] like Figure 2 and Figure 4As shown, an arc groove 24 is formed at one end of the first support plate 23, and a second support plate 6 is hingedly connected to one end of the first support plate 23 with the arc groove 24. An arc groove 24 is also formed at one end of the second support plate 6 close to the first support plate 23, and grooves 7 are formed on the upper surfaces of the first support plate 23 and the second support plate 6.

[0032] like Figure 2 and Figure 3 As shown, a protective assembly is provided on the second support plate 6, and the protective assembly includes a pair of fixed blocks 20 provided on one side of the second support plate 6, and a protective cover 16 is rotatably provided between the two fixed blocks 20.

At this time, the blood will stimulate the luminol reagent coating to make the coating glow. The light sensor set in the light shield will trigger the alarm to promptly remind medical staff to stop dialysis.

[0037] like Figure 1 and Figure 2 As shown, a group of ventilation grooves 13 are provided on the first support plate 4 and the fixed plate 1, and a sliding plate 12 is provided on one side of the bottom end of the two groups of ventilation grooves 13. One side of the two sliding plates 12 is connected to the first support plate 4 and the fixed plate 1 respectively through a folding pad 11, and a hydraulic rod is provided on one side of the sliding plate 12.

[0038] like Figure 1 and Figure 2As shown, a neck support 9 is provided at one end of the second support plate 3 close to the first support plate 4, and the neck support 9 is made of soft material; the neck support 9 can prevent the patient's neck from being suspended in the air for a long time and causing neck muscle strain.

One end of any massage roller 34 is coaxially connected to a motor 33, and the free ends of all massage rollers 34 are coaxially connected to sprockets 37, and all sprockets 37 are connected by a transmission chain 35.

[0040] The massage component and the ventilation slot 13 can improve the comfort of the patient during long-term dialysis. When the patient feels that the surrounding environment is hot, the hydraulic rod can be driven to extend and retract, so that the hydraulic rod drives the sliding plate 12 to move. The folding pad 11 connected to one side of the sliding plate 12 will change the shielding area of ​​the ventilation slot 13, thereby adjusting the ventilation degree of the ventilation slot 13 to help the patient cool down.

[0041] The massage assembly can promote blood circulation in the patient's lower limbs to avoid restless legs syndrome. When the motor 33 is started, the motor 33 will drive the massage rollers 34 coaxially connected thereto to rotate. Since the free ends of all the massage rollers 34 are coaxially connected to sprockets, and all the sprockets are connected by a transmission chain 35, the motor 33 will drive all the massage rollers 34 to rotate synchronously to massage the patient's lower limbs.

[0042] The specific usage and function of this embodiment are as follows:

[0043] The fixing assembly and the protection assembly provided in the present invention can fix the position of the patient's arm to a certain extent, and at the same time can prevent the patient's limb movement from squeezing the dialysis tube. After the patient undergoes dialysis puncture, the patient's arm needs to be placed at the top of the side groove 8 so that the patient's upper arm contacts the connecting seat 26 and the upper surface of the first support plate 23. The distance between the first support plate 23 and the connecting seat 26 is adjusted according to the length of the patient's forearm, and the rotating plate 32 is rotated. The rotating rod 31 coaxially connected to the rotating plate 32 will drive the second bevel gear 30 coaxially connected to the other end thereof to rotate, so that the rotating rod 31 meshing with the second bevel gear 30 is meshed with the second bevel gear 30. When the first bevel gear 29 rotates, the screw 25 coaxially connected to the first bevel gear 29 will cause the first support plate 23 to move along the axis of the screw 25. At this time, the first support plate 23 will move along the insertion rods 21 on both sides of the connecting seat 26 until the position where the first support plate 23 and the second support plate 6 are provided with arc grooves 24 is moved to the patient's elbow joint. At this time, the patient's forearm is placed on the second support plate 6, so that the patient's forearm is in contact with the groove 7 provided on the second support plate 6, and then the protective cover 16 set by the rotating protective assembly through the fixed block 20 is rotated to a horizontal position.

[0044] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
