DETAILED DESCRIPTION

[0018] The present application is now described in further detail in conjunction with the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the present application in a schematic manner, and therefore only show the components related to the present application.

[0019] like Figure 1-11 As shown, the multifunctional infusion device comprises an infusion chair 1, both sides of which are provided with movable support arms 2 for supporting the arms, and the movable support arms 2 are hingedly arranged at one end away from the hands of the infusion recipient, so as to be arranged to drive the forearms of the infusion recipient to swing under the drive of external force.

[0020] The width direction of the infusion chair 1 is defined as the left-right direction, and the axial length direction of the movable support arm 2 is defined as the front-back direction.

[0021] The infusion chair 1 is similar in structure to a conventional chair, and also comprises a seat, legs and a backrest.

[0022] The difference is that in the present application, a movable support arm 2 is used to replace the armrests on the left and right sides of the transmission chair, so that when the infusion recipient sits on the infusion chair 1 for infusion, his arms can be placed on the movable arms, and the movable support arm 2 can be driven by external force to move, so as to synchronously drive the infusion recipient's arms to perform passive movements, thereby ensuring the normal progress of the infusion and avoiding needle dislocation, and appropriately performing certain activities on the infusion recipient's arms that have been kept motionless for a long time, thereby reducing the sense of stiffness caused by the infusion.

[0023] like Figure 3 and Figure 4 As shown, in some further embodiments, a mounting block 6 is slidably provided on the infusion chair 1 along the length direction of the movable support arm 2 , and the movable support arm 2 is hingedly provided in the mounting block 6 .

[0024] In order to further ensure the adjustment effect of the infusion recipient's arm, the entire movable support arm 2 can also move in the front and rear directions. Specifically, the movable support arm 2 is hingedly arranged in the mounting block 6, and the mounting block 6 is slidably arranged on the side of the backrest of the infusion chair 1.

[0025] like Figure 4 and Fig.11 As shown, in some further embodiments, a first ball head 60 is provided at one hinged end of the movable support arm 2, a connecting rod 600 is extended from the first ball head 60, and a second ball head 67 is provided on the connecting rod 600, and the first ball head 60 and the second ball head 67 are both located on the axial straight line of the movable support arm 2; a first ball socket 601 is provided on the mounting block 6, and the first ball head 60 is hingedly arranged in the first ball socket 601; an X-axis sliding shaft 61 and a Y-axis sliding shaft 62 are provided on the side of the mounting block 6 facing away from the movable support arm 2, a first push rod 610 is slidably provided on the X-axis sliding shaft 61, a second push rod 620 is provided on the Y-axis sliding shaft 62, and the pushing ends of the first push rod 610 and the second push rod 620 are both hinged to the second ball head 67.

[0026] The first ball socket 601 is disposed at the front side wall opening of the mounting block 6. In a specific implementation, the mounting block 6 may be a shell structure consisting of two shells connected together by screws.

[0027] The first ball head 60 is connected to the movable support arm 2 via a connecting column 63 , and the connecting column 63 , the first ball head 60 , and the movable support arm 2 can all be connected by screwing to meet assembly requirements.

[0028] The connection between the connecting rod 600 and the first ball head 60 can also be achieved by screwing.

[0029] The connecting rod 600 and the connecting column 63 are respectively located on both sides of the first ball head 60, and the first ball head 60 is hinged in the first ball socket 601. When the connecting rod 600 is pressed downward, the end of the movable support arm 2 away from the mounting block 6 swings upward, and when the connecting rod 600 is lifted upward, the end of the movable support arm 2 away from the mounting block 6 swings downward. Similarly, when the connecting rod 600 is pushed to the left, the end of the movable support arm 2 away from the mounting block 6 swings to the right, and when the connecting rod 600 is pushed to the right, the end of the movable support arm 2 away from the mounting block 6 swings to the left.

[0030] like Figure 4 As shown, a support rod 602 is provided on the side of the mounting block 6 facing away from the movable support arm 2, and the number of the support rods 602 is four, and the four support rods 602 are arranged in a 2x2 manner, wherein the two ends of the X-direction sliding shaft 61 are respectively connected to two of the support rods 602 in the horizontal direction, and the two ends of the Y-direction sliding shaft 62 are respectively connected to two of the support rods 602 in the vertical direction, and in order to ensure the stability of the frame formed by the support rods 602, the X-direction sliding shaft 61 and the Y-direction sliding shaft 62, two X-direction sliding shafts 61 and two Y-direction sliding shafts 62 are each provided, that is, two X-direction sliding shafts 61 are arranged at intervals up and down, and two Y-direction sliding shafts 62 are arranged at intervals left and right.

[0031] The upper ball head of the second ball head 67 is matched with an adjusting block 603 , and the pushing end of the first push rod 610 and the pushing end of the second push rod 620 are both connected to the adjusting block 603 .

[0032] When the first push rod 610 on the X-axis sliding shaft 61 is extended, the adjustment block 603 presses the second ball head 67 downward, and the second push rod 620 on the Y-axis sliding shaft 62 slides downward synchronously, and the end of the movable support arm 2 away from the mounting block 6 swings upward; when the first push rod 610 is shortened, the second push rod 620 on the Y-axis sliding shaft 62 slides upward synchronously, and the end of the movable support arm 2 away from the mounting block 6 swings downward.

[0033] When the first push rod 610 on the Y-axis sliding shaft 62 is extended, the adjustment block 603 pushes the second ball head 67 to the left, and the first push rod 610 on the X-axis sliding shaft 61 slides to the left synchronously, and the end of the movable support arm 2 away from the mounting block 6 swings to the right; when the second push rod 620 is shortened, the first push rod 610 on the X-axis sliding shaft 61 slides to the right synchronously, and the end of the movable support arm 2 away from the mounting block 6 swings to the left.

[0034] like Fig.11As shown, it should be particularly noted that the second ball head 67 is in an articulated motion state relative to the first ball head 60. Therefore, the motion trajectory of the second ball head 67 is not a plane, but an arc surface (spherical surface). For this reason, the connecting rod 600 is set as an elastic telescopic structure, such as the abutment sleeve 6002 and the abutment rod 6001 are sleeved together, and an abutment spring 6003 is set inside the abutment sleeve 6002, so that the abutment spring 6003 is in a compressed state, so that the second ball head 67 can adaptively extend and retract along the axial direction of the connecting rod 600, so as to ensure that the adjustment block 603 can stably cooperate with the second ball head 67.

[0035] In some other embodiments, the first push rod 610 and the second push rod 620 can be extended or shortened at the same time, thereby driving the movable support arm 2 to swing to the upper left, lower left, upper right, and lower right, so that the forearm of the infusion recipient can fully move passively.

[0036] like Figure 4 and Fig.10 As shown, in some further embodiments, a slide rail 65 is provided on the backrest of the infusion chair 1, a slider 650 is connected to the mounting block 6, and the slide rail 65 and the slider 650 are slidably matched; a first motor 64 is provided on the backrest of the infusion chair 1, and a screw 66 is provided on the transmission shaft of the first motor 64, and the screw 66 is threadedly matched with the slider 650.

[0037] The slide rail 65 is arranged on the side wall of the backrest. When the first motor 64 rotates, the first motor 64 drives the screw rod 66 to rotate. The screw rod 66 is screwed to the slider 650, thereby driving the mounting block 6 to slide along the sliding direction of the slide rail 65 to move the arm of the infusion recipient in the front and back directions.

[0038] like Fig.10 As shown, in some further embodiments, a rotating assembly 653 is provided between the mounting block 6 and the slider 650, and the rotating assembly 653 includes a connecting arm 651 and an articulated arm 652, one end of the connecting arm 651 is connected to the slider 650, and the other end is provided with a second motor 654, one end of the articulated arm 652 is connected to the transmission end of the second motor 654, and the other end is connected to the mounting block 6.

[0039] In order to further increase the flexibility of the movement of the movable support arm 2, a rotating assembly 653 is arranged between the mounting block 6 and the slider 650. When the second motor 654 rotates, the articulated arm 652 will drive the mounting block 6 to rotate, thereby driving the movable support arm 2 to rotate synchronously, so as to drive the infusion recipient's forearm to rotate. Moreover, the movable support arm 2 does not simply rotate around the axis, but also works together with the swing in different directions to form movements in different directions, thereby fully moving the infusion recipient's forearm.

[0040] It should be noted that the range of motion of the movable support arm 2 should not be too large, and the speed of the corresponding drive motor should also be moderate, which can be set specifically according to actual conditions.

[0041] like Figure 5 As shown, in some further embodiments, a third push rod 21 is provided inside the movable support arm 2, the extension direction of the third push rod 21 is the same as the axial direction of the movable support arm 2, the extended end of the third push rod 21 extends toward the end of the movable support arm 2 where the hand of the infusion recipient is located, and a third motor 22 is provided on the extended end, and a palm rest 20 is provided at the transmission end of the third motor 22.

[0042] The palm rest 20 is a spherical structure as a whole, and its outer contour is mainly used to be covered by the palm, that is, it plays a certain supporting role on the open palm to prevent the finger ends from directly contacting the plane support and causing the fingers to move and cause the needle to fall off.

[0043] The third motor 22 is used to drive the palm rest 20 to swing up and down. When the infusion is being injected, the palm rest 20 can be controlled to swing downward to avoid interfering with the fist of the infusion recipient. After the injection, when the infusion recipient gradually spreads his fingers, the palm rest 20 can be swung upward to provide support for the palm.

[0044] The third push rod 21 is disposed inside the movable support arm 2 and is used to control the distance between the palm support 20 and the movable support arm 2 to cope with different infusion users.

[0045] like Figure 1 and Figure 2 As shown, in some further embodiments, a movable frame 4 is elastically clamped on the backrest of the infusion chair 1, and an infusion frame is slidably provided on the mobile frame 4 along the width direction of the backrest; a shoulder strap 42 and a waist belt 43 that can be connected to the infusion recipient are provided on the mobile frame 4; a waist support 41 and a back support 40 are provided on the side of the mobile frame 4 facing the infusion recipient.

[0046] The infusion time is inevitably relatively long. For the infusion recipient whose body functions are still in a normal state, appropriate activities can greatly alleviate the discomfort caused by long-term sitting during infusion. Therefore, in this embodiment, a movable frame 4 that can be separated from the infusion chair 1 is specially provided. When the infusion recipient wants to perform certain activities, the shoulder strap 42 and the waist belt 43 can be tied on the back, thereby achieving the function of infusion while doing slight activities.

[0047] At the same time, in order to improve the comfort of the infusion recipient in the sitting state, a backrest 40 and a waistrest 41 are also provided on the movable frame 4.

[0048] In some further embodiments, the infusion stand includes a sleeve 50, a sliding rod 51, a first cantilever 52 and a second cantilever 53. The lower end of the sleeve 50 is connected to the movable frame 4, the sliding rod 51 is slidably sleeved in the sleeve 50, one end of the first cantilever 52 is hinged to the top end of the sliding rod 51, and the other end of the first cantilever 52 is hinged to one end of the second cantilever 53. A hook 54 is provided at the end of the second cantilever 53 away from the first cantilever 52.

[0049] like Figure 7 As shown, the locking between the sleeve 50 and the sliding rod 51 is achieved by a fixing bolt 500, which is radially arranged along the tube wall of the sleeve 50, and abuts against the outer wall of the sliding rod 51 when rotating inward to achieve locking, and moves away from the outer wall of the sliding rod 51 when rotating outward to achieve unlocking.

[0050] like Figure 8 As shown, an annular step 510 is provided on the top of the sliding rod 51, and the annular bottom surface of the annular step 510 is provided with a circle of first engaging teeth 511. A rotating sleeve 520 is provided on the first cantilever 52, and the annular lower end surface of the rotating sleeve 520 is provided with second engaging teeth 521. The rotating sleeve 520 is sleeved on the top of the sliding rod 51, and the first engaging teeth 511 and the second engaging teeth 521 are engaged with each other. At the same time, a locking ring 522 is rotated on the end of the sliding rod 51. When it is rotated downward, the locking ring 522 presses the rotating sleeve 520 to move downward so that the first engaging teeth 511 and the second engaging teeth 521 are engaged with each other. When it is necessary to adjust the rotation angle of the first cantilever 52 relative to the sliding rod 51, the locking ring 522 can be rotated upward so that the first engaging teeth 511 and the second engaging teeth 521 are in a state where they can be disengaged, thereby achieving adjustment, and then the locking ring 522 is locked.

[0051] The first cantilever 52 and the second cantilever 53 are hingedly connected by bolts and nuts, which is common in the prior art and will not be described in detail here.

[0052] The hook 54 is used for hanging an infusion bag (bottle).

[0053] like Figure 6 As shown, in some further embodiments, a sliding rail 44 is provided on the side of the mobile frame 4 facing away from the infusion recipient, a sliding block 45 is provided on the sliding rail 44, and a sleeve 50 is arranged on the sliding block 45; a plurality of limiting holes 440 are provided on the sliding rail 44 and arranged axially apart from the sliding rail 44, a mounting groove 453 is provided in the sliding block 45, a limiting rod 450 is provided on the sliding block 45 to slide through the mounting groove 453, a first spring 451 is sleeved on a section of the limiting rod 450 passing through the mounting groove 453, a limiting handle 452 is provided on the limiting rod 450, and the first spring 451 is located between the limiting handle 452 and the groove wall of the mounting groove 453 to prevent the limiting rod 450 from sliding out of the limiting hole 440.

[0054] The sliding block 45 can move along the sliding rail 44. When the infusion recipient is receiving an infusion with his right hand, the sliding block 45 can be pushed to move rightward. When the infusion recipient is receiving an infusion with his left hand, the sliding block 45 can be pushed to move leftward.

[0055] Pull the limit rod 450 backward, the first spring 451 is compressed, and the limit rod 450 is pulled out of the limit hole 440. At this time, the sliding block 45 can be moved along the sliding rail 44. When it moves into place, release the limit rod 450. Under the action of the first spring 451, the limit rod 450 is correspondingly inserted into the corresponding limit hole 440 to fix the sliding block 45.

[0056] The limiting handle 452 can be welded to the limiting rod 450 .

[0057] like Figure 2 and Fig. 9 As shown, in some further embodiments, there are two lumbar supports 41, and an adjusting rod 410 is provided on the side of the two lumbar supports 41 facing away from the infusion recipient. A threaded hole is penetrated through the movable frame 4, and an adjusting column 412 is screwed into the threaded hole. The adjusting column 412 is rotatably engaged with the adjusting rod 410, and a second spring 413 is provided between the lumbar support 41 and the movable frame 4, and the second spring 413 is sleeved on the adjusting rod 410.

[0058] The waist support 41 is an arc-shaped plate structure, on which a corresponding cotton pad can be provided to increase comfort.

[0059] A mounting hole is provided on one end face of the adjusting column 412 facing the adjusting rod 410, and a bearing 411 is provided in the mounting hole. The outer ring of the bearing 411 is interference fit with the inner wall of the mounting hole, and the end of the adjusting rod 410 is interference fit with the inner ring of the bearing 411, thereby realizing the rotational fit between the adjusting column 412 and the adjusting rod 410.

[0060] When the lumbar support 41 needs to be adjusted forward, the adjusting column 412 is rotated forward, and the adjusting column 412 moves toward the lumbar support 41 , thereby driving the lumbar support 41 to move forward. The second spring 413 is in a compressed state to prevent the adjusting rod 410 from rotating with the adjusting column 412 .

[0061] like Figure 3 As shown, in some other embodiments, baffles 46 are provided on both sides of the notch in the backrest for setting the movable frame 4, and a corresponding slot 10 is provided on the rear side of the movable frame 4. When the movable frame 4 is matched with the notch, the slot 10 and the baffle 46 are just engaged with each other.

[0062] Elastic pads are provided on the side wall of the baffle 46 that contacts the slot 10 and the side wall of the slot 10 that contacts the baffle 46, so that there is a certain damping when the two are connected, ensuring that the movable frame 4 can be stably connected to the backrest under human conditions.

[0063] It is worth mentioning that the infusion stand in this embodiment is located at the rear side of the infusion recipient, which can greatly increase the activity space in front of the infusion recipient and also reduce the risk of the infusion belt being accidentally touched.

[0064] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection created by this application.
