Description

A catheter fixing frame

Technical Field

The utility model belongs to the technical field of medical auxiliary equipment, and in particular relates to a catheter fixing frame.

Background Art

A medical catheter is a thin tube made of medical grade materials that has a wide range of functions. A medical catheter is a medical device that can be inserted into the body to treat a disease or perform a surgical procedure. Medical catheters are manufactured for specific applications, such as cardiovascular, urological, gastrointestinal, neurovascular, and ophthalmic surgery. In most uses, a catheter is a thin, flexible tube (soft catheter), but catheters vary in stiffness depending on the application. Medical catheters can be inserted into body cavities, ducts or blood vessels, the brain, the skin, or adipose tissue. Functionally, they allow drainage, administration of fluids or gases, entry of surgical instruments, and also perform a variety of other tasks depending on the type of catheter. Special types of catheters, also called probes, are used in preclinical or clinical research for sampling lipophilic and hydrophilic compounds, protein-bound and unbound drugs, neurotransmitters, peptides and proteins, antibodies, nanoparticles and nanocarriers, enzymes, and vesicles. There are many categories of medical catheters, which can be roughly divided into the following according to their functions: 1. Infusion catheters; 2. Hemodialysis catheters; 3. Angiography catheters; 4. Catheters for intravascular interventional therapy; 5. Digestive tract catheters; 6. Respiratory tract catheters; 7. Urinary system catheters; 8. Nervous system catheters; 9. Surgical drainage catheters, etc.

In many medical applications, the fixation method of the catheter is crucial to ensure that it can work safely and effectively. Common fixation methods are as follows: 1. Tube clamp fixation method: This is one of the most common ways to fix the catheter. The catheter is fixed in the appropriate position by using a tube clamp of appropriate size. It is suitable for catheters with smaller diameters; 2. Tube tape fixation method: For catheters with larger diameters, using tube tapes for fixation is an effective method. The tube tape can be made of double-sided tape with strong adhesion or a binding with an adjustable rubber band; 3. Fixing method with fixing clip: In some cases, the catheter needs to be fixed to the fixing clip to ensure its stability. It is suitable for catheters that require additional support; 4. Fixing method with fixing frame: For some large diversion systems, a fixing frame is usually required for fixation and support. The fixing frame can be a special metal frame, or a hook or bracket, which can ensure that the catheter is fixed in the correct position and reduce the impact of pressure and tension on the catheter.

The existing catheter fixing frame cannot be adjusted and fixed according to the length of the catheter. During drainage, the catheter is easily bent, resulting in poor drainage effect, causing harm to the patient. In addition, different patients may have different hanging heights even if the same affected part is in different time periods, and it needs to be adjusted at any time according to the patient's body position changes. When treating patients, it is necessary to keep the catheter pipeline unobstructed, not to be compressed and twisted, and not to be bent into an angle to avoid affecting drainage. Therefore, when burying drainage tubes in patients clinically, adhesive tape is usually used to fix the drainage tubes. This operation is very troublesome and is prone to the problem of loose fixation, which increases the difficulty of work for medical staff. When there are a large number of drainage tubes, the use of adhesive tape to fix them often causes interference between the drainage tubes, and it is easy for multiple drainage tubes to be entangled with each other, increasing the burden on medical staff.

Utility Model Content
