Description

Technical Field

[0001] This utility model belongs to the technical field of intensive care, specifically relating to a catheter fixation device. Background Technology

[0002] In intensive care and other medical settings, the stability and safety of intravenous lines are crucial for patient treatment. Traditional methods of securing intravenous lines often use tape or disposable fixation devices. Tape fixation is prone to flattening or bending of the intravenous line due to patient movement or turning, increasing the risk of obstructed venous return and affecting treatment outcomes. While disposable fixation devices are more stable than tape, they are prone to loosening after prolonged use, especially when the patient is frequently active, and cannot guarantee continuous fixation.

[0003] Existing fixation devices are cumbersome to replace and are mostly disposable, leading to frequent changes during care, increasing medical costs and the workload of nursing staff. Traditional fixation methods are prone to contamination at the application site, especially after prolonged use, increasing the risk of infection. Rigid or disposable fixation devices may cause pressure or irritation to the patient's skin, affecting patient comfort and sleep quality.

[0004] To address the aforementioned issues, this invention proposes an innovative catheter fixation device. By designing a rotatable clamp, an upper fixation mechanism, a limiting and elastic pre-tightening structure, a modular connection design, and a contamination-resistant protective layer, it aims to improve the stability and ease of operation of venous catheter fixation while considering cost control and patient comfort. This provides a safer, more efficient, and economical venous catheter fixation solution for medical scenarios such as intensive care. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides, for example Figures 1-5The illustrated catheter fixation device includes an intravenous tube 1. A right clamp 2 is disposed on the outer side of the right end of the intravenous tube 1, and a left clamp 3 is disposed on the outer side of the left end of the intravenous tube 1. The intravenous tube 1 is clamped between the right clamp 2 and the left clamp 3. A connecting base 4 is snapped onto the lower end of the right clamp 2 and the left clamp 3. An adhesive dressing 5 is fixedly connected to the lower end of the connecting base 4, and the connecting base 4 is fixedly connected to the upper center of the adhesive dressing 5. A protective layer 6 is attached to the lower end of the adhesive dressing 5. This device is used for cardiac intensive care patients. When inserting a venous catheter into tube 1, one end of tube 1 is connected to the jugular vein via a venous needle, and the other end is connected to the drug pump device. Tube 1 can be fixed by the right splint 2 and the left splint 3, and is attached to the vicinity of the neck via the connecting base 4 and the adhesive dressing 5. This ensures the stable connection of tube 1 and prevents the tube 1 from being flattened or bent when the patient turns over, which could lead to unstable blood pressure. The adhesive dressing 5 can only be exposed at the lower end after the protective layer 6 is removed, ensuring that the lower adhesive area of ​​the adhesive dressing 5 is not contaminated.

[0027] Preferably, the right clamping plate 2 and the left clamping plate 3 are rotatably connected by a clamping groove 9 and a clamping shaft 10. The clamping groove 9 is formed inside the lower left side of the right clamping plate 2. The clamping shaft 10 is fixedly connected to the lower right side of the left clamping plate 3 and is rotatably connected inside the clamping groove 9. It is also rotatably connected to the lower left side of the right clamping plate 2 by shafts at both ends. A fixing head 11 is fixedly connected to the upper left side of the right clamping plate 2. A fixing groove 12 extends through the upper right side of the left clamping plate 3 from left to right. The fixing head 11 can pass between the right clamping plate 2 and the left clamping plate 3. The rotating part is inserted into the fixed slot 12 and fixes the upper side between the right clamp 2 and the left clamp 3. Since the lower side between the right clamp 2 and the left clamp 3 is rotatably connected by the clamping rotating slot 9 and the clamping rotating shaft 10, and the upper side between the right clamp 2 and the left clamp 3 can be fixed by the fixed clamp head 11 and the fixed slot 12, the upper side between the right clamp 2 and the left clamp 3 can be opened by rotation. At this time, the intravenous tube 1 is placed between the right clamp 2 and the left clamp 3, and the right clamp 2 and the left clamp 3 rotate towards each other to close the upper end, thereby clamping the intravenous tube 1 between the right clamp 2 and the left clamp 3.

[0028] Preferably, limit slots 13 are provided on the inner walls of the right clamp 2 and the left clamp 3 at both ends near the joint. Limiting rods 14 are engaged within the two limit slots 13 inside the right clamp 2 and the two limit slots 13 inside the left clamp 3. Pre-tightening pads 15 are fixedly connected between the two limit rods 14 inside the right clamp 2 and between the two limit rods 14 inside the left clamp 3. Both pre-tightening pads 15 are elastic and are positioned between the vein tube 1 and the inner walls of the right clamp 2 and the left clamp 3, respectively. During the clamping process of the vein tube 1 by the right clamp 2 and the left clamp 3, the pre-tightening pads 15... 5 is elastic and located inside the right splint 2 and left splint 3 near the joint. Therefore, the two pre-tightening pads 15 can wrap around the outside of the vein tube 1 through the closure of the upper ends of the right splint 2 and left splint 3. When the right splint 2 and left splint 3 are completely closed, the two pre-tightening pads 15 adhere to the inner wall of the right splint 2 and left splint 3 under the compression of the vein tube 1. This allows the right splint 2 and left splint 3 to increase the clamping force on the vein tube 1 through the two pre-tightening pads 15. At the same time, the elasticity of the two pre-tightening pads 15 can prevent the vein tube 1 from loosening inside the right splint 2 and left splint 3, so that the vein tube 1 can be firmly and stably fixed between the right splint 2 and left splint 3.

[0029] Preferably, both the right splint 2 and the left splint 3 are connected to the connecting base 4 via two connecting slots 7 and two connecting heads 8. The four connecting slots 7 are respectively located inside the two lower right corners of the right splint 2 and the two lower left corners of the left splint 3. The four connecting heads 8 are respectively fixedly connected to the four upper corners of the connecting base 4, and the four connecting heads 8 are respectively engaged inside the four connecting slots 7. After the intravenous tube 1 is fixed, the right splint 2 and the left splint 3 can be engaged at the upper end of the connecting base 4 via the connecting slots 7 and connecting heads 8, and fixed near the patient's neck via the connecting base 4 and the adhesive dressing 5. The right splint 2 and the left splint 3 can be disengaged from the connecting base 4 by being disengaged from the connecting slots 7 via the connecting heads 8. This allows the patient to re-fix the intravenous tube 1 by simply replacing the connecting base 4 and the adhesive dressing 5 during the nursing process, making the right splint 2 and the left splint 3 reusable and eliminating the need for repeated fixation of the intravenous tube 1. This reduces nursing costs and improves nursing efficiency.
