Description

Technical Field

[0001] The utility model belongs to the technical field of medical fixing patches, in particular to an 8-shaped catheter fixing patch. Background Art

[0002] Vascular access is a prerequisite for hemodialysis. In the short term of dialysis and critical care, before long-term vascular access is established, internal jugular vein catheterization is the most commonly used temporary vascular access for hemodialysis due to its advantages such as simple operation, safety, few complications, less pain for patients, high success rate, sufficient blood flow, and long retention time. However, the neck has a large and frequent range of motion, loose skin, vigorous secretion of sweat glands and sebaceous glands, and hair around it, plus the exposed length of the dialysis catheter is relatively long, so fixation is difficult. The expert consensus on clinical venous catheter maintenance and operation points out that attention should be paid to the integrity of the catheter fixing device, the patient's skin condition, comfort, and potential risk of skin damage. The auxiliary external fixation device should be used and replaced by one person, and the catheter fixation should not affect the observation of the puncture point, cause blood circulation disorders, and cannot affect the function of the catheter.

[0003] Studies have shown that traditional medical tape is not used to fix internal jugular vein catheters firmly, which can cause iatrogenic skin damage, low patient comfort, and increase the risk of bleeding and infection at the puncture site.

[0004] In addition to adhesive tape fixation, the current domestic neck catheter fixation devices include lace protection bag type, neck restraint belt type, ear hook type, elastic cap type, etc. Each fixation method has limitations and is not promoted in relevant guidelines and specifications;

[0005] The special fixing device for temporary internal jugular vein cannulation uses Velcro to stick the protective cover and the base together. The Velcro is hard and there is a risk of skin damage.

[0006] Neck restraint type, ear hanging type, elastic cap type device, can only be used in a fixed position, and when the temperature is high in summer, the neck restraint type, elastic cap type device will significantly reduce the patient's comfort.

[0007] To this end, those skilled in the art have proposed an 8-shaped catheter fixing patch to solve the problems raised by the background technology. Utility Model Content

[0008] In order to solve the above technical problems, the utility model provides an 8-shaped catheter fixing patch to solve the problem that the medical tape in the prior art cannot fix the internal jugular vein catheter firmly, causing iatrogenic skin damage, low patient comfort, and increased risks of bleeding and infection at the puncture point.

[0009] An 8-shaped catheter fixing patch comprises a low-sensitivity adhesive tape and a fixing component; a connecting portion is provided at the central axis of the low-sensitivity adhesive tape, the fixing component comprises a rope body and an 8-shaped knot, and both ends of the rope body pass through the connecting portion and the 8-shaped knot, and rope knots are connected at both ends of the rope body.

[0010] Preferably, the rope body passes through two holes of the figure-8 knot to form a first fixing loop and a second fixing loop; the first fixing loop and the second fixing loop form an 8-shaped structure.

[0011] Preferably, the figure-8 knot is an "8"-shaped structure.

[0012] Preferably, the connecting portion is an inverted "U"-shaped structure.

[0013] Preferably, through grooves are formed on both side walls of the connecting portion.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The utility model forms a first fixing loop and a second fixing loop with the rope body by arranging a low-sensitivity adhesive tape, a rope body and an 8-shaped knot. The low-sensitivity adhesive tape can be attached not only to a planar position of the human body, but also to a non-planar position, so that the application range of the fixing patch is wider. The pipeline is fixed by the second fixing loop. When the patient's head and neck move, the low-sensitivity adhesive tape follows the displacement. Since the connecting part has a certain displacement space, the pulling force of the head and neck movement on the pipeline can be buffered, so that the pipeline is in a relatively stable state. At the same time, the pulling force of the pipeline on the base low-sensitivity adhesive tape can be reduced, and the use time of the fixing patch can be extended. The low-sensitivity adhesive tape is only the size of a Band-Aid, and can be attached to different parts of the neck, cheek, auricle, behind the ear, etc. according to the position of the pipeline. It is lighter, more convenient and convenient to use, and the nursing quality of the pipeline during retention is improved.

[0016] 2. The utility model can adjust the radius of the first fixing ring and the second fixing ring by setting the figure-8 knot, so that the second fixing ring can fix pipelines with different diameters. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0022] Example: As attached Figure 1 To Attachment Figure 2 As shown: The utility model provides an 8-shaped catheter fixing patch, including a low-sensitivity adhesive tape 1 and a fixing component 4, the low-sensitivity adhesive tape 1 is 3.2 cm long, a connecting portion 2 is provided at the central axis of the low-sensitivity adhesive tape 1, the fixing component 4 includes a rope body 5 and an 8-shaped knot 403, the rope body 5 is about 10 cm long, and both ends of the rope body 5 pass through the connecting portion 2 and the 8-shaped knot 403, and knots 404 are connected at both ends of the rope body 5; through the low-sensitivity adhesive tape 1, the fixing patch can be pasted on different parts such as the neck, cheek, auricle, and behind the ear according to the position of the pipeline.

[0023] The rope body 5 passes through the two holes of the figure-8 knot 403 to form a first fixing loop 401 and a second fixing loop 402; the first fixing loop 401 and the second fixing loop 402 form an 8-shaped structure; the first fixing loop 401 is a small "8"-shaped loop, and the first fixing loop 401 is fixed on the low-sensitivity adhesive tape 1 through the connecting part 2, and the second fixing loop 402 is a large "8"-shaped loop, and the pipeline is fixed by the second fixing loop 402; the 8-shaped structure is formed by the first fixing loop 401 and the second fixing loop 402, and when the patient's head and neck move, the low-sensitivity adhesive tape 1 follows the displacement. Since the connecting part 2 has a certain displacement space, the pulling force generated by the head and neck movement on the pipeline can be buffered, so that the pipeline is in a relatively stable state. At the same time, the pulling force generated by the pipeline on the base low-sensitivity adhesive tape 1 can be reduced, thereby extending the use time of the fixing patch.

[0024] The figure-8 knot 403 is an "8"-shaped structure, the connecting portion 2 is an inverted "U"-shaped structure, and through grooves 3 are provided on both side walls of the connecting portion 2; the first fixing ring 401 is connected to the low-sensitivity adhesive tape 1 through the through grooves 3 and the inverted "U"-shaped connecting portion 2; the radius of the first fixing ring 401 and the second fixing ring 402 can be adjusted through the figure-8 knot 403, so that the second fixing ring 402 can fix pipelines of different diameters.

[0025] As can be seen from the above, the catheter fixing patch is mainly used for fixing temporary catheters for hemodialysis; when the patient is sitting or semi-sitting and lying, and naturally relaxed, observe the natural placement of the exposed pipeline, and stick the low-sensitivity tape 1 2 cm below the highest point of the pipeline to fix the pipeline in the second fixing circle 402; it is also applicable to the fixation of other pipelines: such as CVC, femoral vein catheterization, etc.; because the low-sensitivity tape 1 can not only be attached to the flat position of the human body, but also to the non-planar position, the application range of the fixing patch is wider; it is especially suitable for parts where the fixing surface is not flat.

[0026] The hypoallergenic tape 1 is only the size of a Band-Aid and can be adhered to different parts of the neck, cheek, auricle, behind the ear, etc. according to the location of the tube. It is lighter, more convenient and easier to use, which improves the care quality of the tube during its retention period and avoids the occurrence of related adverse events.
