Description

Technical Field

[0001] The present invention relates to the technical field of hemodialysis, and in particular to a hemodialysis nursing auxiliary device. Background Art

[0002] In the field of biomedical engineering, hemodialysis is one of the important application directions. Hemodialysis uses a dialyzer to remove toxins, waste and excess water accumulated in the patient's body to help maintain the normal function of the body.

[0003] Chinese patent CN115105661A discloses an auxiliary device for hemodialysis in the Department of Nephrology, which relates to the technical field of medical auxiliary instruments. The auxiliary device for hemodialysis in the Department of Nephrology includes a workbench, the top of which is fixedly connected to a lower fixed seat, the top of which is provided with a lower arc-shaped opening, the upper surface of the workbench and located on the right side of the lower fixed seat is fixedly connected to a first guide rail, the top of the first guide rail is provided with a first sliding seat, the top of the first sliding seat is fixedly connected to a telescopic rod, and the top of the telescopic rod is hingedly connected to an upper fixed seat through a movable connection structure. By providing a lower fixed seat structure, the patient's limbs are placed in the lower arc-shaped opening, and then fixed by the upper fixed seat at the top. One end of the upper fixed seat is hinged, and the other end is tightened by an elastic rope, which has a certain elasticity and will not cause squeezing discomfort to the patient's limbs, and is more convenient to use.

[0004] The above patents and prior art have the following problems:

[0005] During the dialysis process, patients are asked to place their palms upward and their arms on the bed with the skin on the inside of their arms exposed. The nurse will then puncture and connect the arm to the dialysis machine so that the patient's blood can be placed in a circulating dialysis machine. Existing hemodialysis usually requires patients to do it three times a week, with each dialysis lasting 3.5 to 4 hours. During this time period, the arm needs to be kept in a stable position to prevent the needle from falling off. If the inside of the arm is turned upward for a long time, the patient's arm will feel twisted, sore, and pulled, thereby increasing the pain of hemodialysis. At the same time, long-term dialysis can easily cause pressure ulcers on the skin where the arm contacts the bed sheet, further increasing the patient's pain. Severe pressure skin ulcers can also affect subsequent hemodialysis. Summary of the invention

[0030] Beneficial effects of the present invention:

[0031] The patient's arm is supported mainly by the bottom arc support plate and the support ring. At this time, the restraint belt does not restrain the patient's arm and is in a relaxed state. The blood transfusion tube is elastically squeezed by the elastic member inside the sleeve, so that the elastic member pushes the movable rod downward, and the movable rod pushes the tube pressing plate passing through the blood transfusion tube to contact the patient's forearm, thereby reducing the phenomenon of needle removal caused by accidental shaking of the blood transfusion tube.

[0032] When the patient feels a sore and swollen feeling when turning his arm, the patient controls the rotation of the driving member by operating the external remote control connected to the driving member and the winding power source by Bluetooth, so that the driving member drives the linkage rod and the transmission member to rotate synchronously through the rotation of the active member and the driven member, so that the transmission member drives the alternating support plate to rotate toward the bottom of the support ring, that is, to move toward the back of the patient's arm during the rotation, and then when the transmission member rotates and drives the alternating support plate to move to the back of the patient's arm, the winding power source is moved by operating the external remote control, so that the winding power source drives the winding roller to rewind through the transmission chain belt, so that the excess restraining belt is retracted to the surface of the winding roller, so that the tube pressing plate drives the blood transfusion tube to be constrained to the inside of the patient's arm, thereby reducing the deviation of the blood transfusion tube during subsequent adjustment;

[0033] The initial state of the tube pressing plate is that the movable rod connected to the tube pressing plate and the penetrating rod at the top of the sleeve are placed inside the placement groove and the arc cavity, so that the tube pressing plate is always located at the top of the arm, and when the alternating support plate moves from the side of the support ring to the bottom of the support ring, the front end of the arc cavity will move away from the block, and the end of the arc cavity will contact the penetrating rod, and then in the process of the alternating support plate moving from the side of the support ring to the bottom of the support ring, the penetrating rod is always in the placement groove, thereby reducing the bending of the blood transfusion tube caused by the rotation of the alternating support plate.

[0034] After the restraint belt restrains the arm and the tube pressing plate to the surface of the alternating support plate, continue to operate the driving part to rotate, so that the alternating support plate drives the flipping arm to move slowly, so that the arm is finally flipped to a near right angle under the traction and rotation of the alternating support plate, that is, the thumb of the patient's arm is transferred from a flat state to an upright state. In this process, the restraint belt prevents the accidental movement of the blood transfusion tube during rotation, and drives the patient's arm to rotate, so that the contact surface area of ​​the patient's arm with the support ring and the bottom arc support plate is changed, thereby reducing the problem of arm skin ulcers caused by long-term dialysis, so that the patient can independently drive the arm to flip through the above-mentioned equipment under the premise of reducing upper body activities.

[0035] The rotating rod drives the driving wheel and the synchronous member to rotate, so that the synchronous member drives the driven wheel to rotate, and the driven wheel drives the surrounding tube to rotate, so that the length margin of the blood transfusion tube wrapped around the surface of the surrounding tube is released, thereby increasing the activity margin of the blood transfusion tube when the arm is rotated by the alternating support plate, and reducing the occurrence of accidental needle removal of the blood transfusion tube.

[0064] Operation process:

[0065] Initially, the nurse wraps the blood transfusion tube connected to the two connection holes 305 around the surface of the tube wrapping member 304. The tube wrapping member 304 is mainly used to control the length of the blood transfusion tube. The tube wrapping member 304 is cylindrical, which can reduce the obstruction of the blood flow when the blood transfusion tube is wrapped. Then, the blood transfusion tube that has passed through the tube wrapping member 304 passes through the through-tube 20244, the through-hole 20611 and the wire groove 2062 in sequence and is placed on the side of the bottom arc support plate 203, so that the needle at the front end of the blood transfusion tube can be inserted into the patient's arm for blood exchange.

[0066] By rotating the fastener 2011, the fastener 2011 releases the restriction on the rotating column 2025, and the end of the rotating rod 20241 rotates inside the equipment body 301, so that when the adjusting wheel 302 is moved to drive the equipment body 301 to move outward, the rotating column 2025 will be driven to rotate outward through the rotating rod 20241, so that the angle between the bottom arc support plate 203, the support ring 204 and the alternating support plate 205 and the bed body 1 can be adjusted, so that the nursing adjustment unit 2 can adapt to patients of different body shapes. After adjustment, the fastener 2011 is rotated to press the fastener 2011 against the inner wall of the rotating column 2025 to complete the locking.

[0067] Then the patient passes his arm through the positioning ring 2031, the restraining belt 2054 and the supporting ring 204 in sequence, so that the patient's arm is restricted and supported by the bottom arc support plate 203 and the supporting ring 204, and the open bottom arc support plate 203 receives the patient's upper arm, so that the patient's upper arm is turned over and the inner blood vessels face upwards. The nurse inserts the needle of the blood transfusion tube into the inner side of the patient's upper arm, so that one blood transfusion tube transfers the patient's blood into the interior of the device body 301, and the other blood transfusion tube transfers the dialyzed blood of the device body 301 into the patient's body.

[0068] At this time, the patient's arm is mainly supported by the bottom arc support plate 203 and the support ring 204. At this time, the restraint belt 2054 does not restrain the patient's arm and is in a relaxed state. Under the elastic compression of the elastic member 20642 inside the sleeve 2064, the elastic member 20642 pushes the movable rod 20641 downward, so that the movable rod 20641 pushes the tube pressing plate 206 passing through the blood transfusion tube to contact the patient's forearm, thereby reducing the phenomenon of needle dislodging caused by accidental shaking of the blood transfusion tube.

[0083] Furthermore, the support ring 204 is movably sleeved on the left and right sides of the alternating support plate 205, a moving rail 2042 is provided on the inner side of the support ring 204, a placement groove 20421 is provided on the bottom side of the end of the moving rail 2042, and a clamping plate 2043 is symmetrically provided on the inner wall of the support ring 204;

[0084] Connecting rings 2055 are symmetrically arranged on the left and right sides of the alternating support plate 205, and a raised ring 20551 is arranged on the outer ring of the connecting ring 2055. The raised ring 20551 is movably arranged on the inner side of the clamping plate 2043, and an arc cavity 2056 is arranged on the surface of the connecting ring 2055. One side of the penetrating rod 20651 is movably clamped in the inside of the placement groove 20421, and the other side of the penetrating rod 20651 is movably clamped in the inside of the arc cavity 2056.

[0085] Operation process:

[0086] When the patient feels a sore and swollen feeling when turning his arm, the patient controls the driving member 2024 to rotate by operating the external remote control connected to the driving member 2024 and the winding power source 2052 by Bluetooth, so that the driving member 2024 drives the linkage rod 20223 and the transmission member 20224 to rotate synchronously through the rotation of the active member 20221 and the driven member 20222, so that the transmission member 20224 drives the alternating support plate 205 to rotate toward the bottom of the support ring 204, that is, to move toward the back of the patient's arm. It should be noted that the alternating support plate 205 The top of the opening will not contact the patient's arm when rotating, and then when the transmission member 20224 rotates to drive the alternating support plate 205 to move to the back of the patient's arm, the reeling power source 2052 is moved by operating the external remote control, so that the reeling power source 2052 drives the reel 2053 to reel through the transmission chain belt 20521, so that the excess restraining belt 2054 is reeled onto the surface of the reel 2053, so that the tube pressing plate 206 drives the blood transfusion tube to be constrained to the inside of the patient's arm, thereby reducing the deviation of the blood transfusion tube during subsequent adjustment;

[0087] It should be noted that there is a gap between the blood transfusion tube passing through the tube pressing plate 206 and the patient's skin, so the blood transfusion tube will not be squeezed when the tube pressing plate 206 is constrained, thereby ensuring the normal dialysis of the patient.

[0088] The initial state of the tube pressing plate 206 is that the movable rod 20641 connected to the tube pressing plate 206 and the penetrating rod 20651 on the top of the sleeve 2064 are placed in the placement groove 20421 and the arc cavity 2056, so that the tube pressing plate 206 is always located at the top of the arm, and when the alternating support plate 205 moves from the side of the support ring 204 to the bottom of the support ring 204, the front end of the arc cavity 2056 will move away from the block 2065, and the end of the arc cavity 2056 will contact the penetrating rod 20651, and then in the process of the alternating support plate 205 moving from the side of the support ring 204 to the bottom of the support ring 204, the penetrating rod 20651 is always in the placement groove 20421, thereby reducing the bending of the blood transfusion tube caused by the alternating support plate 205 during the rotation process.

[0089] After the restraint belt 2054 restrains the arm and the tube pressing plate 206 to the surface of the alternating support plate 205, continue to operate the driving member 2024 to rotate, so that the alternating support plate 205 drives the flipped arm to move slowly, so that the arm is finally flipped to a near right angle under the traction and rotation of the alternating support plate 205, that is, the thumb of the patient's arm is transferred from a flat state to an upright state. In this process, the restraint belt 2054, on the one hand, prevents the accidental movement of the blood transfusion tube during rotation, and on the other hand, drives the patient's arm to rotate, so that the contact surface area of ​​the patient's arm with the support ring 204 and the bottom arc support plate 203 is changed, thereby reducing the problem of arm skin ulcers caused by long-term dialysis, so that the patient can independently drive the arm to flip through the above-mentioned equipment under the premise of reducing upper body activities.

[0090] The rotation of the driving member 2024 will also drive the driving wheel 20245 and the synchronous member 20246 to rotate through the rotating rod 20241, so that the synchronous member 20246 drives the driven wheel 20247 to rotate, and the driven wheel 20247 drives the surrounding tube 304 to rotate, so that the length margin of the blood transfusion tube wrapped around the surface of the surrounding tube 304 is released, thereby increasing the activity margin of the blood transfusion tube when the alternating support plate 205 drives the arm to rotate, and reducing the occurrence of accidental needle removal of the blood transfusion tube.
