Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, in particular to an adjusting and fixing device for a dialysis tube. Background Art

[0002] Renal dialysis is also called artificial kidney. Artificial kidney is a device that replaces kidney function and is mainly used to treat renal failure and uremia. It draws blood out of the body and uses dialysis, filtration, adsorption, membrane separation and other principles to eliminate excess nitrogen compounds, metabolic products or excessive drugs in the body, adjust electrolyte balance and then draw the purified blood back into the body. It also uses the human body's biological membrane (such as peritoneum) for blood purification. In the process of hemodialysis treatment in nephrology, dialysis tubes must be used, and the fixation of dialysis catheters is very important, because the dialysis tube may be involved if you are not careful. In nephrology dialysis, the shaking of the dialysis tube will bring some unnecessary pain to the patient, and may even bring worse effects. Generally, the dialysis tube fixing device used in nephrology is in close contact with the human skin, making the skin around the wound less breathable. Long-term fixation may cause skin allergies, etc., and there are no disinfection measures around the wound, which may cause severe wound infection. The dialysis tube fixing device used in nephrology is fixed on the human skin and will shake due to the human body's breathing. It is not stable and it is not convenient to adjust the height and angle.

[0003] Announcement No. CN215135567U discloses a dialysis tube fixing device for kidney dialysis, which is provided with a fixing device to make the whole device more stable and prevent random shaking. It is provided with a lifting device and an angle adjustment device to make the dialysis tube more smoothly connected to the patient and relieve the patient's pain. It is provided with a tube groove, a first fixing belt and a second fixing belt to allow the dialysis tube to be stably fixed on the device to prevent the dialysis tube from shaking, which not only reduces the patient's pain, but also facilitates the doctor to observe and treat, and increases the success rate of the patient's recovery. However, the patent still has the following problems in actual use:

[0004] Although the dialysis tube fixing device for kidney dialysis is provided with a fixing device, which can make the whole device more stable and prevent it from shaking randomly, it is unable to fix the dialysis tube. When the patient is undergoing dialysis, the dialysis tube may move or be pulled, which may easily cause the dialysis tube to fall off, thereby affecting the patient's normal dialysis. At the same time, the pulling of the dialysis tube may have a certain impact on the patient's wound and affect the safety of the patient's dialysis. In the prior art, the dialysis tube is clamped and fixed by a clamp, but this may cause the dialysis tube to deform, thereby affecting the blood flow in the dialysis tube.

[0005] Therefore, an adjusting and fixing device for a dialysis tube is proposed to solve the above-mentioned problems. Summary of the invention

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the adjusting and fixing device for dialysis tube uses the contraction arc plate on the outer side of the winding bracket to evenly wind the dialysis tube, and at the same time, the threaded knob is rotated to drive the movable threaded rod to move inside the threaded sleeve, thereby driving the clamping movable plate to move, and under the action of the clamping rotating rod and the second clamping support, the rotation of the clamping rotating arm is realized, thereby clamping and limiting the dialysis tube, starting the winding motor to drive the winding roller to rotate, and under the action of the roller bracket and the fixed pulley, the winding connecting rope pulls the winding bracket to move, thereby adjusting the angle of the winding bracket, and can adapt to the dialysis state of various dialysis tubes. The specific contents are as follows:

[0022] 1. By setting up the winding and fixing mechanism, not only can the contraction arc plate on the outer side of the winding bracket be used to evenly wind the dialysis tube, but also the movable threaded rod can be driven to move inside the threaded sleeve by rotating the threaded knob, thereby driving the clamping movable plate to move. Under the action of the clamping rotating rod and the second clamping support, the rotation of the clamping rotating arm is realized, thereby clamping and limiting the dialysis tube, and the elastic force of the clamping spring is used to realize the clamping connection between the clamping block and the limiting toothed disc, which can realize the rotation of the first clamping support and the limiting of the first clamping support, and is convenient for changing the rotation direction of the clamping rotating arm, thereby adapting to dialysis tubes with different numbers of spiral turns. When the dialysis tube is pulled, the dialysis tube is contracted. The arc plate is spirally wound, so the dialysis tube can be extended, and the diameter of the spiral becomes smaller, thereby squeezing and contracting the arc plate. Under the elastic force of the contraction spring, the dialysis tube can be buffered and reset at the same time, so as to avoid the dialysis tube being damaged due to pulling, thereby affecting the dialysis effect and avoiding secondary damage to the patient's wound. At the same time, the guide heating bottom plate and the guide heating top plate can be opened by using the magnetic buckle and the connecting hinge, and the two dialysis tubes can be placed in the guide heating tank for heating, so that the blood entering the patient's body has a certain temperature, so as to avoid the patient from catching a cold. At the same time, the two dialysis tubes can be limited to avoid confusion of the dialysis tubes.

[0023] 2. By setting up an adjustment and fixing mechanism, the moving roller at the bottom of the sealing sleeve can be used to realize the movement of the fixed base. When the entire device is placed in a fixed position, the two-way threaded rod is driven to rotate by turning the lifting knob, so that the two first lifting threaded sleeves move relatively and the lifting rotating rod is driven to rotate at the same time, so that the distance between the fixed base and the lifting support plate can be adjusted. Since the lifting support plate is fixedly connected to the sliding lifting rod, when the lifting support plate is adjusted, the sliding lifting rod drives the sealing sleeve and the moving roller to move upward. When the sealing sleeve is connected with the internal clamping connection of the fixed suction cup, the fixed suction cup is closely fitted to the ground under the action of the gravity of the entire device, thereby fixing the entire device and improving the stability of the device. When the entire device needs to be moved, the distance between the fixed base and the lifting support plate can be shortened to make the sealing The sleeve and the movable roller extend from the inside of the fixed suction cup, so that the fixed suction cup loses suction, thereby facilitating the movement of the entire device. The rotating motor drives the rotating worm to rotate, and the meshing connection between the rotating worm and the rotating worm wheel is utilized to rotate the lifting bracket, so as to facilitate the adjustment of the orientation of the winding and fixing mechanism. By setting a counterweight connecting rod and a counterweight ring, the stability of the winding and fixing mechanism can be improved to avoid the phenomenon of the device tipping over. The lifting motor drives the lifting threaded rod to rotate, so that the second lifting threaded sleeve drives the connecting support and the winding bracket to move up and down, so as to adjust the height of the winding bracket. At the same time, the winding motor is started to drive the winding roller to rotate. Under the action of the roller bracket and the fixed pulley, the winding connecting rope pulls the winding bracket to move, thereby adjusting the angle of the winding bracket, which can adapt to the dialysis states of various dialysis tubes.

Under the action of the roller bracket 228 and the fixed pulley 229, the winding connecting rope 227 pulls the winding bracket 101 to move, thereby adjusting the angle of the winding bracket 101, which can adapt to the dialysis status of various dialysis tubes.

[0041] Working principle: Before using this adjustment and fixing device for dialysis tube, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Fig.11As shown, first, the dialysis tube is evenly wound by using the contraction arc plate 107 on the outer side of the winding bracket 101, and at the same time, the movable threaded rod 125 is driven to move inside the threaded sleeve 123 by rotating the threaded knob 124, thereby driving the clamping movable plate 122 to move, and under the action of the clamping rotating rod 119 and the second clamping support 121, the rotation of the clamping rotating arm 120 is realized, so as to clamp and limit the dialysis tube, and the elastic force of the clamping spring 116 is utilized to realize the clamping connection between the clamping block 117 and the limiting toothed disk 111, which can realize the rotation of the first clamping support 118 and the limiting of the first clamping support 118, so as to facilitate changing the rotation direction of the clamping rotating arm 120, so as to adapt to dialysis tubes with different spiral turns. When the dialysis tube is pulled, due to the dialysis tube The dialysis tube is spirally wound on the contraction arc plate 107, so that the dialysis tube can be extended, and the diameter of the spiral becomes smaller, thereby squeezing the contraction arc plate 107. Under the elastic force of the contraction spring 104, the dialysis tube can be buffered and reset at the same time, so as to avoid the dialysis tube being damaged due to pulling, thereby affecting the dialysis effect and avoiding secondary damage to the patient's wound. At the same time, the magnetic buckle 129 and the connecting hinge 130 can be used to open the guide heating bottom plate 127 and the guide heating top plate 131, and the two dialysis tubes can be placed in the guide heating groove 128 for heating, so that the blood entering the patient's body has a certain temperature to avoid the patient from catching a cold. At the same time, the two dialysis tubes can be limited to avoid confusion of the dialysis tubes.

[0042] Secondly, the moving roller 205 at the bottom of the sealing sleeve 204 is used to realize the movement of the fixed base 201. When the entire device is placed in a fixed position, the two-way threaded rod 208 is driven to rotate by turning the lifting knob 207, so that the two first lifting threaded sleeves 209 move relative to each other and the lifting rotating rod 210 is driven to rotate, so that the distance between the fixed base 201 and the lifting support plate 206 can be adjusted. Since the lifting support plate 206 is fixedly connected to the sliding lifting rod 203, when the lifting support plate 206 is adjusted, the sliding lifting rod 203 is driven to rotate. The dynamic sealing sleeve 204 and the movable roller 205 move upward, and when the sealing sleeve 204 is engaged with the inside of the fixed suction cup 202, under the action of the gravity of the entire device, the fixed suction cup 202 is closely fitted to the ground, thereby fixing the entire device and improving the stability of the device. When the entire device needs to be moved, the distance between the fixed base 201 and the lifting support plate 206 can be shortened, so that the sealing sleeve 204 and the movable roller 205 extend from the inside of the fixed suction cup 202, causing the fixed suction cup 202 to lose suction, thereby facilitating the movement of the entire device.

[0043] Finally, the rotating motor 213 drives the rotating worm 214 to rotate, and the meshing connection between the rotating worm 214 and the rotating worm wheel 215 is utilized to rotate the lifting bracket 216, so as to facilitate the adjustment of the orientation of the winding and fixing mechanism 1. By setting the counterweight connecting rod 217 and the counterweight ring 219, the stability of the winding and fixing mechanism 1 can be improved to avoid the phenomenon of the device tipping over. The lifting motor 221 drives the lifting threaded rod 222 to rotate, so that the second lifting threaded sleeve 223 drives the connecting support 132 and the winding bracket 101 to move up and down, so as to adjust the height of the winding bracket 101. At the same time, the winding motor 225 is started to drive the winding roller 226 to rotate. Under the action of the roller bracket 228 and the fixed pulley 229, the winding connecting rope 227 pulls the winding bracket 101 to move, thereby adjusting the angle of the winding bracket 101, so as to adapt to the dialysis state of various dialysis tubes.
