Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically to a multifunctional waist belt suitable for drainage catheters. Background Technology

[0002] In the medical field, drainage of fluid accumulation in the pleural cavity, abdominal cavity, and pericardium is a common treatment method. Existing drainage tubes typically require the use of specific catheters, which need to be secured during use to prevent accidental dislodgement. Current fixation devices are mostly simple bandages or tapes, which cannot effectively meet the needs of patients during activity and are prone to displacement or dislodgement of the drainage tube.

[0003] Currently, various types of drainage tube fixation devices exist on the market, but most designs lack ergonomic considerations. Existing fixation devices often use a single material and structure, failing to adapt to the different body shapes and activity levels of various patients. The fixation method of the drainage tube usually relies on external pressure, which may cause discomfort to patients during activity. Furthermore, existing fixation devices also present certain difficulties in cleaning and replacement, affecting the patient's experience and safety.

[0004] Existing drainage tube fixation devices have several problems. First, the fixation effect is poor, easily leading to unplanned removal of the drainage tube and increasing patient risk. Second, existing devices lack design flexibility and cannot adapt to different patients' physical conditions, causing inconvenience during movement. Finally, existing fixation devices are also inadequate in cleaning and maintenance, potentially leading to complications such as infection. Therefore, there is an urgent need for a new fixation device to improve the safety of drainage tubes and patient comfort. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this invention is to provide a novel drainage tube fixing device that can effectively fix the drainage tube, adapt to the body shape and activity needs of different patients, and facilitate cleaning and maintenance.

[0006] This utility model is a multifunctional waist belt for drainage catheters. Three Velcro straps are fixed on both sides and the back of the waist belt for securing the drainage tube. The ends of the waist belt use sliding buckles with adjustable length. The waist belt has two fixing rings and a flip-top anti-pull-out device is installed on the waist belt. The flip-top anti-pull-out device includes an outer circular shell and multiple one-way valves inside. One end of a retractable cord is fixed inside the circular shell, and the other end of the retractable cord is connected to a circular lock for suspending the drainage bag. The back of the circular shell is fixed to the waist belt.

[0007] This invention uses self-adhesive Velcro attached to the outer periphery of the retractable cord to prevent the drainage bag's negative pressure extension tube from becoming too long, which would cause tangling and tangle.

[0008] Each Velcro strap should be 3-5 cm wide and 10-15 cm long.

[0009] The height of the flip-top anti-pull device is less than the width of the belt.

[0010] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] This utility model, by adopting the above technical solutions, has the following advantages: By using comfortable materials and an adjustable design, it significantly improves the safety of drainage tube fixation and patient comfort, reducing the risk of unplanned tube removal. Simultaneously, the flip-top anti-pull-out device effectively prevents accidental removal of the drainage tube, enhancing safety. The self-adhesive Velcro and retractable cord design simplify drainage tube management, avoiding clutter and tangling, and improving the patient's user experience. Furthermore, the overall design facilitates cleaning and maintenance, reducing the risk of complications such as infection, thereby improving patient safety and comfort. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of the structure of this utility model;

[0013] Figure 2 This is a schematic diagram of the flip-top anti-pulling tube device of this utility model. Detailed Implementation

[0014] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0015] like Figure 1-2 As shown, three Velcro straps 2 are fixed on both sides and the back of the waist belt 1 for securing the drainage tube. One end of the waist belt uses a sliding buckle 3 with adjustable length. The waist belt has two fixing rings for securing the excess part at the end of the waist belt. The other end of the waist belt is fitted with a buckle that engages with the sliding buckle. A flip-top anti-pull-out device 4 is installed on the waist belt. The flip-top anti-pull-out device includes an outer circular shell 8 and multiple one-way valves 5 inside. An openable button self-locking switch is provided on the outside of the flip-top anti-pull-out device. One end of the retractable cord 9 is fixed inside the circular shell, and the other end of the retractable cord is connected to a circular buckle 7 for suspending the drainage bag. The back of the circular shell is fixed to the waist belt. Self-adhesive Velcro straps 6 are provided on the outer periphery of the retractable cord to prevent mess and tugging caused by excessive length of the negative pressure extension tube of the drainage bag.

[0016] The following is a detailed description of each part:

[0017] 1. Comfortable waist belt design

[0018] This implementation plan designs a comfortable waist belt. The belt should be 5-10 cm wide and made of soft, skin-friendly materials such as polyester or cotton to ensure no irritation upon direct skin contact. The inside of the belt should be designed to be breathable to reduce dampness and discomfort caused by prolonged wear. The belt can be light-colored to facilitate matching with clothing in daily life.

[0019] 2. Velcro fastening device

[0020] Three Velcro straps are designed on both sides and the back of the waist belt for securing the drainage tube. Each Velcro strap should be 3-5 cm wide and 10-15 cm long to ensure a secure hold and prevent pulling due to movement. The adhesive strength of the Velcro straps should be tested to ensure they do not easily come off during patient movement, while still allowing for easy removal when needed.

[0021] 3. Adjustable waist belt design

[0022] Considering the varying waist circumferences among clinical patients, the waist belt should be designed with an adjustable tightness. A sliding buckle or loop design allows the belt to accommodate patients with waist circumferences ranging from 60 to 120 centimeters. By adjusting the tightness of the belt, patients can customize it to their comfort level, ensuring no restriction or discomfort during activity. Two retaining loops are also included to secure any excess belt, preventing it from sagging or becoming tangled.

[0023] 4. Flip-top anti-pull-out device

[0024] This implementation plan introduces a flip-top anti-pull-out device. The device has a circular outer shell, approximately 10 cm in diameter, and contains multiple one-way valves similar to venous valves. The valves should be made of silicone or rubber to ensure flexibility and durability. The drainage tube passes through the center of the valves; when the tube is pulled upwards, the valves open smoothly; conversely, when the tube is pulled downwards, the valves effectively prevent the tube from being pulled out due to one-way resistance. The height of the flip-top anti-pull-out device should be less than the width of the waist belt to prevent the temperature of the device housing from causing discomfort to the patient.

[0025] 5. Retractable cord design

[0026] A retractable cord securing device should be designed within the flip-top anti-pull-out device. The cord length should be adjustable, with a maximum length of 1.5 meters, to ensure it does not restrict patient movement. The cord should be made of a durable yet flexible material to extend its lifespan.

[0027] 6. Application of self-adhesive hook and loop fasteners

[0028] To address the issue of tangled drainage tubes caused by excessive length, a self-adhesive Velcro closure was designed. This Velcro closure, 2-3 cm wide and 15-20 cm long, effectively secures the drainage tube, preventing it from sagging or becoming tangled. Patients simply attach the drainage tube to the Velcro closure for a neat and safe procedure.

[0029] 7. Circular buckle design

[0030] Finally, a circular latch, approximately 5 cm in diameter, is designed, primarily for suspending the drainage bag. The latch should be made of corrosion-resistant plastic or metal to ensure its lifespan in humid environments. The latch's design should facilitate easy attachment and removal by the patient, preventing the drainage bag from falling and thus reducing the risk of tube dislodgement.

[0031] The above embodiments are only used to illustrate this utility model. The structure, connection method and manufacturing process of each component can be changed. All equivalent transformations and improvements made on the basis of the technical solution of this utility model should not be excluded from the protection scope of this utility model.
