Description

Technical Field

[0001] This utility model relates to the field of urinary catheter support, specifically a bedside urinary catheter anti-slip fixing device. Background Technology

[0002] In clinical nursing, many patients have to use urinary catheters to urinate due to surgery or other causes. Indwelling urinary catheter is a common nursing procedure, widely used in postoperative urinary retention, urine output monitoring in critically ill patients, and urination management in long-term bedridden patients. However, accidental slippage of the urinary catheter may cause urethral injury and urinary tract infection. At the same time, repeated catheterization will increase the patient's pain. In this case, the method of fixing and placing the urinary catheter is particularly important for the convenience of the patient after the illness.

[0003] In existing technologies, urinary catheters are mostly fixed by binding or by direct fixation with other flexible materials. This passive fixation lacks adaptability and is difficult to adapt to the traction force caused by changes in the patient's body position, leading to catheter displacement. Moreover, slippage can only be detected by nursing staff or the patient's family through visual observation and regular rounds, making it difficult to address the issue of early warning before dislodgement. Among these fixation methods, stability is clearly insufficient, operation is cumbersome, and patient safety cannot be protected. Therefore, we propose a bedside urinary catheter anti-slip fixation device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a bedside catheter anti-slip fixing device to solve the problems mentioned in the background art.

[0005] The technical solution of this utility model is: a bedside urinary catheter anti-slip fixing device, comprising a first half-ring, a screw at one end of the first half-ring, a connecting rod at the other end of the first half-ring, a quick-release plate rotatably connected to one end of the screw, a second half-ring rotatably connected to one end of the connecting rod, a quick-release mechanism fixedly connected to the surface of the first half-ring, a support rod on the surface of the first half-ring, a base plate fixedly connected to the other end of the support rod, a ratchet structure on the front side wall of the base plate, and a buzzer mechanism on the front side wall of the base plate, with the two ratchet mechanisms and the buzzer mechanism arranged in a mirror image.

[0006] Preferably, the quick-release mechanism includes two symmetrically arranged first limiting plates, and a second limiting plate is rotatably connected to the inner walls of the two first limiting plates. One end of the second limiting plate is fixedly connected to one end of the support rod. A through hole is provided on the side wall of the first limiting plate, and the through hole passes through the side walls of the two first limiting plates. The same quick-release bolt is rotatably connected to the inner wall of the through hole, and the side walls of the two first limiting plates are rotatably connected to the side walls of the second limiting plate.

[0007] Preferably, the ratchet mechanism includes two symmetrically arranged ratchet walls, the rear ends of which are rotatably connected to the front sidewall of the base plate. Three annularly distributed springs are fixedly connected to the inner walls of the two ratchet walls. A ratchet tooth is fixedly connected to the end of each spring away from the ratchet wall. The ratchet tooth is rotatably connected to the inner wall of the ratchet wall. A ratchet is provided inside the ratchet wall, and the rear end of the ratchet is fixedly connected to the front sidewall of the base plate.

[0008] Preferably, the buzzer mechanism includes two buzzer outer rings, one end of each buzzer outer ring is fixedly connected to one end of an adjacent ratchet wall, and a battery slot is fixedly connected to the inner wall of each buzzer outer ring. A button battery is disposed on the inner wall of the battery slot. The button battery is electrically connected to a buzzer plate, the buzzer plate is electrically connected to a music chip, and the music chip is electrically connected to a conductive spring plate.

[0009] Preferably, the surface of the ratchet wall is provided with an arc-shaped groove, which is made of rubber.

[0010] Preferably, the ratchet teeth are disposed abutting against the surfaces of the ratchet wheel, and the ratchet teeth are matched with the ratchet wheel.

[0011] This utility model provides an improved bedside catheter anti-slip fixing device, which has the following improvements and advantages compared with the prior art: Firstly, this utility model, by setting ratchet teeth to slide on the surface of the ratchet wheel and using the ratchet wheel to be fixedly connected to the base plate, can realize the clockwise movement of the ratchet wheel wall and the rubber groove, thereby allowing the urinary catheter to be stretched towards the patient end. When the urinary catheter moves in the opposite direction, it will give the ratchet wheel wall and the arc groove a force to move in the opposite direction. Since the ratchet teeth and the ratchet wheel are set to abut against each other, they cannot achieve counterclockwise rotation, thus constraining the urinary catheter when it is stretched in the opposite direction towards the patient end.

[0012] Secondly, this utility model, by setting an outer ring for the buzzer, when the rotation speed is too fast, the ratchet wall is fixedly connected to the outer ring of the buzzer, which will then drive the outer ring of the buzzer to rotate. When the outer ring of the buzzer rotates, due to the high speed, the conductive spring sheet will contact the right side wall of the battery compartment due to centrifugal force. Through electrical connection, the music chip is energized and emits a buzzing signal, which is transmitted to the buzzer sheet, thereby causing the buzzer sheet to emit a buzzing sound for the purpose of reminder.

[0015] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0016] This utility model provides an improved bedside catheter anti-slip fixing device. The technical solution of this utility model is as follows: like Figure 1 - Figure 3 As shown, a bedside catheter anti-slip fixing device includes a first half-ring 1, a screw 2 at one end of the first half-ring 1, a connecting rod 4 at the other end of the first half-ring 1, one end of the screw 2 being rotatably connected to one end of the first half-ring 1, a quick-release plate 3 being rotatably connected to the surface of the screw 2, one end of the connecting rod 4 being rotatably connected to one end of the first half-ring 1, and a second half-ring 5 being rotatably connected to the other end of the connecting rod 4, a quick-release mechanism being fixedly connected to the surface of the first half-ring 1, a support rod 9 being provided on the surface of the first half-ring 1, a base plate 10 being fixedly connected to the other end of the support rod 9, a ratchet structure being provided on the front side wall of the base plate 10, and a buzzer mechanism being provided on the front side wall of the base plate 10, with the two ratchet mechanisms and the buzzer mechanism being arranged in a mirror image.

[0017] Furthermore, the quick-release mechanism includes two symmetrically arranged first limiting plates 6, with a second limiting plate 8 rotatably connected to the inner walls of the two first limiting plates 6. One end of the second limiting plate 8 is fixedly connected to one end of the support rod 9. A through hole is provided on the side wall of the first limiting plate 6, penetrating the side walls of the two first limiting plates 6. The same quick-release bolt 7 is rotatably connected to the inner wall of the through hole. The side walls of the two first limiting plates 6 are rotatably connected to the side walls of the second limiting plate 8. By rotating the quick-release bolt 7, the quick-release bolt 7 can rotate within the first limiting plate 6 and the second limiting plate 8 through the through hole in the side walls of the first limiting plate 6 and the second limiting plate 8, thereby unlocking the mechanism.

[0018] Furthermore, the ratchet mechanism includes two symmetrically arranged ratchet walls 11. The rear ends of both ratchet walls 11 are rotatably connected to the front side wall of the base plate 10. Three annularly distributed springs 13 are fixedly connected to the inner walls of both ratchet walls 11. The ends of the three springs 13 away from the ratchet walls 11 are respectively fixedly connected to ratchet teeth 14. The ratchet teeth 14 are rotatably connected to the inner walls of the ratchet walls 11. A ratchet 15 is arranged inside the ratchet wall 11. The rear end of the ratchet 15 is fixedly connected to the front side wall of the base plate 10. By setting the ratchet walls 11 and springs 13, and by using the ratchet teeth 14 and ratchet 15 to abut against each other, unidirectional rotation of the ratchet teeth 14 and ratchet 15 can be achieved.

[0019] Furthermore, the buzzer mechanism includes two buzzer outer rings 16, one end of which is fixedly connected to one end of an adjacent ratchet wall 11. A battery slot 17 is fixedly connected to the inner wall of each buzzer outer ring 16. A button battery 18 is provided on the inner wall of the battery slot 17. The button battery 18 is electrically connected to a buzzer 19. The buzzer 19 is electrically connected to a music chip 20. The music chip 20 is electrically connected to a conductive spring 21. By providing the conductive spring 21, the centrifugal force generated by the rotation can make the conductive spring 21 contact one end of the battery slot 17, thereby making the battery slot 19 emit a buzzing sound.

[0020] Furthermore, the surfaces of the ratchet 14 and the ratchet 15 are abutted together, and the ratchet 14 and the ratchet 15 are matched. By setting the ratchet 14 and the ratchet 15 to abut each other, the ratchet 14 and the ratchet 15 can be rotated synchronously in one direction.

[0021] Furthermore, the arc-shaped groove 12 is made of rubber. By setting the arc-shaped groove 12 and utilizing its rubber material, the friction between the arc-shaped groove 12 and the urinary catheter can be increased.

[0022] Working principle: By rotating the quick-release plate 3, one end of the second half-ring 5 is disengaged. Since the first half-ring 1, connecting rod 4, and second half-ring 5 are rotatably connected, the screw 2 can be disengaged from the second half-ring 5, thus achieving quick release. The first limiting plate 6 and the second limiting plate 8 are rotatably connected by the quick-release bolt 7. Rotating the quick-release bolt 7 can also separate the first half-ring 1 from the support rod 9, thereby allowing for the replacement of different fixing ends and achieving applications with different fixing conditions in different scenarios. Since the base plate 10 is rotatably connected to the ratchet wall 11, and the base plate 10 is fixedly connected to the ratchet 15, when the ratchet 14 moves clockwise along the surface of the ratchet 15... When the needle rotates, the ratchet wall 11 and the arc groove 12 also rotate, enabling the insertion and removal of the urinary catheter between the patient and the device, reducing the risk of injury to the patient. When the ratchet wall 11 rotates too fast, the centrifugal force will cause the conductive spring plate 21 to form an electrical connection with the battery slot 17, thus establishing a circuit path. This will cause the music chip 20 to send a signal, causing the buzzer 19 to emit a buzzing sound to remind the patient or medical staff. Since the ratchet 14 and the ratchet 15 are set to abut against each other, the ratchet wall 11 and the arc groove 12 cannot rotate counterclockwise, thus preventing the urinary catheter from being pulled in the opposite direction, further fixing the urinary catheter and protecting the patient's safety.

[0023] The foregoing description enables those skilled in the art to implement or use this invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this invention. Therefore, this invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
