Description

Technical Field

[0001] The utility model relates to a fixing device, in particular to a catheter fixing device. Background Art

[0002] Dialysis generally refers to a method of removing metabolic waste, excess water and toxic substances from the patient's body through artificial intervention. It can be divided into hemodialysis and peritoneal dialysis. Hemodialysis generally requires nurses to operate, draw blood out of the body, and exchange it with dialysate through a dialysis machine and dialysis membrane. The toxic substances in the blood will be excreted from the body after the exchange of dialysis fluid, and then the clean blood will be returned to the body. Peritoneal dialysis is a process of exchanging with peritoneal dialysis fluid through the function of the peritoneum itself to excrete toxins from the body. Mild patients can undergo peritoneal dialysis in the hospital or at home through a negative pressure bag. Generally, patients undergoing peritoneal dialysis need to reserve a peritoneal dialysis tube in the waist and abdomen. When dialysis is needed, the peritoneal dialysis fluid is introduced into the human abdominal cavity through an external tube, and then the accumulated fluid in the abdominal cavity is drawn out to the negative pressure device to achieve peritoneal dialysis treatment. Peritoneal dialysis generally requires several hours of treatment, so the external catheter needs to be fixed on the patient to avoid the catheter being pulled at will, which may cause danger to the treatment.

[0003] For example: According to the medical catheter holder with patent authorization announcement number CN210170642U, it includes: a fixing seat, the bottom end surface of the fixing seat is connected with a non-woven patch, and the non-woven patch is used to fix the fixing seat to the human skin; the first side wall of the fixing seat is provided with a processing port.

[0004] During actual medical treatment, after the catheter is fixedly connected to the patient, since the patient does not need to lie down during dialysis and does not have other major diseases, especially when the patient is using a negative pressure bag for dialysis treatment, the patient can walk. Therefore, after the catheter is fixed, if the patient needs to walk or get up, the fixing direction and angle of the catheter also need to be changed accordingly to avoid the catheter twisting and causing the peritoneal dialysis tube to be pushed and affect the patient's body. At this time, the fixator needs to be removed from the patient again, and then the angle connection is changed to meet the patient's needs. This operation causes the catheter to shake, affecting the patient's dialysis treatment. Utility Model Content

[0005] In order to overcome the disadvantage of the existing fixing device that when the connection angle of the catheter needs to be changed, the fixing device needs to be removed from the patient, which will cause the catheter to shake and affect the patient's dialysis treatment, the utility model provides a catheter fixing device.

[0006] Technical solution: A catheter fixing device includes a strap, a turntable, a card block, a reset spring, a box body, a top cover and a limit assembly. The strap is rotatably connected to the turntable, and a plurality of card blocks are circumferentially slidably connected to the bottom of the turntable.

The three-way card slot on the box body cooperates with the three-way card slot on the right top cover to fix the catheter. The limit assembly is used to limit the left and right top covers on the box body to keep the catheter fixed.

[0007] Furthermore, the limit assembly includes a limit rod, a limit slot is provided inside the box body, the front side of the box body is slidably connected to the limit rod, and the bottom of the top cover is provided with a slot for inserting the limit rod. After the top covers on the left and right sides are closed, the limit rod is inserted into the top cover slots on the left and right sides, thereby limiting the top covers on the left and right sides on the box body.

[0008] Furthermore, the fixing device also includes a countdown timer, a buzzer and a controller. The countdown timer for counting down the dialysis time is fixedly connected to the left side of the top of the box body, and the buzzer and the controller are fixedly connected to the left side of the front side of the box body. The countdown timer and the buzzer are electrically connected to the controller.

[0009] Furthermore, the fixing device also includes a push block, a latch and a return spring. The push block is slidably connected to the rear side of the box body, and the latch is slidably connected to the rear side of the box body. The top of the strap is located at the inner circle of the slot and has multiple limit grooves circumferentially provided. The latch is inserted into one of the limit grooves, and a return spring is connected between the latch and the box body.

[0010] Furthermore, the front side of the top of the push block is inclined, and the push block moves forward to push the latch upward.

[0011] Furthermore, the fixing device also includes a transparent plate, and the transparent plate is fixedly connected to the top of the left top cover.

[0012] Furthermore, the lower end of the clamping block is in the shape of a ball head, and the depth of the clamping groove at the top of the binding strap does not exceed half the height of the ball head at the lower end of the clamping block.

[0013] Furthermore, it also includes a limiting block and a sponge pad. The outlets of the three-way slot on the top of the box body are fixedly connected to the limiting block, and the inside of the three-way slot on the top of the box body is paved with a sponge pad.

[0014] The beneficial effects of the utility model are as follows: 1. The utility model achieves the fixing effect of the catheter by squeezing the box body and the top cover against each other so that the catheter is firmly fixed in the three-way slot, and with the cooperation of the turntable and the card block, it can ensure that the box body can be easily adjusted to a fixed angle and avoid the box body from rotating at will, so that the patient can easily adjust the fixed angle of the catheter according to his or her needs.

[0015] 2. The utility model can facilitate patients to count down for their dialysis treatment through the countdown timer and buzzer. When the specified time is reached, the buzzer automatically sounds an alarm to remind the patient that the dialysis time has arrived, thereby avoiding dialysis timeout.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment: A catheter fixing device, such as Figure 1-Figure 6 As shown, it includes a strap 1, a turntable 2, a card block 3, a reset spring 4, a box body 5, a top cover 7 and a limit assembly. The two ends of the strap 1 are fixedly connected with a Velcro sub-strip and a Velcro mother tape. The top of the strap 1 is rotatably connected to the turntable 2. The bottom of the turntable 2 is slidably connected to no less than six card blocks 3 along the circumferential direction. A reset spring 4 is connected between each card block 3 and the turntable 2. A card slot corresponding to the card block 3 is provided on the top of the strap 1. The lower end of the card block 3 is ball-shaped. The depth of the card slot at the top of the strap 1 does not exceed half of the height of the ball head at the lower end of the card block 3. The top of the turntable 2 is connected to the box body 5 by bolts. The left and right sides of the box body 5 are rotatably connected to the top cover 7. The top right side of the box body 5 is provided with a card slot for adjusting the catheter A three-way card slot 8 is provided for fixing, and a three-way card slot 8 is also provided at the bottom of the right top cover 7. The three-way card slot 8 on the box body 5 cooperates with the three-way card slot 8 on the right top cover 7 to fix the conduit. The limiting component is used to limit the top covers 7 on the left and right sides on the box body 5 to keep the conduit fixed. The limiting component includes a limiting rod 10. A limiting card slot 9 is provided in the middle of the box body 5. The front side of the box body 5 is slidably connected to the limiting rod 10. A slot for inserting the limiting rod 10 is provided on the side close to each other at the bottom of the top cover 7. After the top covers 7 on the left and right sides are closed, the limiting rod 10 is inserted into the top covers 7 on the left and right sides, so as to limit the top covers 7 on the left and right sides on the box body 5.

[0026] When it is necessary to use this fixing device to fix the catheter of a patient who needs dialysis, the device can be first fixed to the patient's thigh by the Velcro sub-stick and Velcro mother stick on the strap 1, and the limiting rod 10 can be pulled out from the limiting card slot 9 of the box body 5 and the slot at the bottom of the top cover 7, and then the right top cover 7 can be opened, and then the catheter connected to the patient's abdomen is placed in the three-way card slot 8 on the box body 5, and the catheter leading to the patient's abdomen and the peritoneal dialysis tube is placed in the empty slot on the front side of the three-way card slot 8, and the catheter leading to the negative pressure bag and one end of the medical bag containing peritoneal dialysis fluid are placed in the two empty slots on the rear side of the three-way card slot 8 in turn, and then the right top cover 7 is covered back on the box body 5, and then the limiting rod 10 is pushed back into the limiting card slot 9 in the box body 5 and the slot at the bottom of the top cover 7, so that the limiting rod 10 limits the right top cover 7 to the top of the box body 5 again, and the bottom of the right top cover 7 is closed. The three-way card slot 8 at the top cooperates with the three-way card slot 8 on the box body 5 to clamp the catheter in the box body 5, thereby achieving the fixation of the catheter, preventing the catheter from swinging arbitrarily during the treatment process, affecting the peritoneal dialysis treatment. If the patient needs to adjust the catheter fixing angle after the catheter is fixed, the box body 5 can be rotated forcefully to drive the turntable 2 to rotate, and the clamping block 3 is pushed out from the clamping slot at the top of the strap 1. At this time, the return spring 4 is compressed, and then the box body 5 and the turntable 2 are continued to be rotated, so as to adjust the appropriate fixing angle according to the patient's needs. After the adjustment, the clamping block 3 is rotated to align with the nearest clamping slot on the strap 1, so that the clamping block 3 is clamped back into the clamping slot under the action of the return spring 4. At this point, the clamping block 3 and the return spring 4 can prevent the box body 5 and the turntable 2 from rotating arbitrarily, and at the same time, the fixing angle of the catheter can be conveniently adjusted according to the needs of the user, which is beneficial to the dialysis treatment of the patient.

[0027] like Figure 1 , Figure 3 and Figure 4 As shown, the fixing device also includes a countdown timer 11, a buzzer 12 and a controller 13. The countdown timer 11 for counting down the dialysis time is fixedly connected to the left side of the top of the box body 5 by means of bolts, and the buzzer 12 and the controller 13 are fixedly connected to the left side of the front side of the box body 5 by means of bolts. The countdown timer 11 and the buzzer 12 are both electrically connected to the controller 13.

[0028] like Figure 1 As shown, the fixing device also includes a transparent plate 17 , and the transparent plate 17 is fixedly connected to the top of the left top cover 7 . The transparent plate 17 is made of a transparent material and is used to conveniently observe the value of the countdown timer 11 .

[0029] When a patient undergoes peritoneal dialysis, since the dialysis time generally takes several hours and the catheter needs to be processed in time after the dialysis is completed, the patient needs to stay awake during the dialysis or needs care from others. In this case, the device can be used for timing, and after the dialysis is completed, the patient can be reminded in time that the dialysis is over. The specific operation is as follows: after the patient starts dialysis, the patient can control the countdown timer 11 to count down through the controller 13, and set a specific time according to the patient's own situation. After the dialysis is officially started, the countdown is started through the countdown timer 11. After the set time is over, the countdown timer 11 sends an electrical signal to the controller 13, and then the controller 13 controls the buzzer 12 to sound an alarm to remind the patient that the set dialysis time has arrived, so as to avoid the dialysis time exceeding the time after the patient falls asleep, which affects the dialysis effect.

[0030] like Figure 5 , Figure 6 and Figure 7 As shown, the fixing device also includes a push block 14, a latch 15 and a return spring 16. The push block 14 is slidably connected to the rear side of the box body 5, and the latch 15 is slidably connected to the inner and rear sides of the box body 5. The top of the strap 1 is located at the inner circle of the card slot and is provided with a plurality of limit grooves along the circumferential direction. The latch 15 is inserted into one of the limit grooves. A return spring 16 is connected between the latch 15 and the box body 5. The front side of the top of the push block 14 is inclined, and the push block 14 moves forward to push the latch 15 upward.

[0031] When the patient conveniently adjusts the fixed angle of the catheter through the turntable 2 and the clamping block 3, although the block 3 and the return spring 4 can prevent the box body 5 from rotating at will, the patient will inevitably need to get up or walk during dialysis, and there is still a risk that the catheter will be pulled by the rotation of the turntable 2 relying solely on the clamping force of the return spring 4. Therefore, the above problem can be solved by the latch 15. The specific operation is as follows: when the fixed angle of the catheter needs to be adjusted according to the user's needs, first press the push block 14 by hand to push the push block 14 into the box The push block 14 is inside the body 5, so that the push block 14 will move forward to squeeze the pin 15 upward, and the pin 15 will be separated from the limiting groove on the binding strap 1. At this time, the return spring 16 is compressed, so that the box body 5 can be rotated. After the fixed angle is rotated, the push block 14 is released, and the push block 14 no longer squeezes the pin 15. The pin 15 is reinserted into the limiting groove on the binding strap 1 under the action of the return spring 16. In this way, the rotation angle of the box body 5 can be stably fixed by the pin 15, avoiding the risk of the catheter being pulled due to the rotation of the box body 5.

[0032] like Figure 3 and Figure 4 As shown, it also includes a limiting block 18 and a sponge pad 19. The outlet of the three-way slot 8 on the top of the box body 5 is fixedly connected to the limiting block 18, and the inside of the three-way slot 8 on the top of the box body 5 is paved with a sponge pad 19.

[0033] When the catheter is fixed in the three-way slot 8, the catheter is pre-tightened by the limit block 18 in the three-way slot 8, so as to facilitate the adjustment of the position of the catheter before fixing it. If there is leakage at the catheter joint during dialysis, the sponge pad 19 can absorb the leakage to prevent the liquid from flowing everywhere.

[0034] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
