Description

Easily-fixed catheter

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a catheter easy to fix.

Background

Indwelling catheterization is a clinical common diagnosis and treatment technology and is a basic means for treating dysuria and observing urine volume. At present, only the retention water sac in the bladder is clinically used as the only internal fixing method of the catheter. Research shows that when a patient with an indwelling catheter gets out of bed or moves on bed, the catheter moves in the urethra to different degrees, and if the patient lacks proper external fixation, the phenomena of urethral or bladder mucosa injury, bladder irritation, urinary tract infection, urine leakage, unsmooth drainage of the catheter, detachment of the catheter and the like can be caused, so that medical workers are troubled for a long time. Therefore, the selection of the proper external fixing mode of the indwelling catheter has important significance on the safety and comfort of the nursing of the urethral catheterization pipeline of the patient. The traditional urinary catheter external fixation method is to fix the urinary catheter on the inner side of the thigh or the abdomen of a patient by adopting a medical adhesive tape, and a high-lift platform method, a tunnel type urinary catheter external fixation method and a strap type fixation method can be adopted. However, due to the gravity of the urinary catheter itself, the traction force of the urinary bag and the friction force generated when the patient moves actively and passively, the medical adhesive plaster is easy to fall off and curl, so that the urinary catheter cannot be properly fixed externally, and needs frequent maintenance by nurses. Other external urinary catheter fixing methods, such as the use of a safety pin or a sewing needle, are easy to cause the urinary tract injury caused by the mistaken traction when the user wears clothes; the appearance and comfort of the non-adhesive velcro and strip fastening devices are poor and are to be further improved.

Detailed Description

The utility model is further illustrated by the following figures and examples.

Example 1:

an easily fixable catheter as shown in fig. 1-4 comprises a catheter 1, a soft magnetic patch 2 and a layer of soft magnetic material 3 in the form of a strip; the soft magnetic material layer 3 is laid on the silica gel wall 11 of the catheter 1 to form a magnetic area at the silica gel wall 11 of the catheter, the magnetic area is located between the catheter water bag 4 and the catheter interface 5 and is close to the catheter interface 5, the closest distance between the top end of the magnetic area and the water bag 4 is 8-20 cm, and the closest distance between the magnetic area and the catheter interface 5 is 3-5 cm; the soft magnetic patch 2 comprises a magnetic layer 8, an adhesive layer 9 and a release film 10; the magnetic layer 8 is attached to one side of the adhesive layer 9, the release film 10 covers the other side of the adhesive layer 9, and the magnetic layer 8 is magnetically connected with the magnetic area. When the urethral catheter is used, the release film 11 is peeled off, the adhesive layer 9 is pasted on the skin of a human body, the urethral catheter 1 is placed above the magnetic layer 8, and magnetic attraction is generated between the urethral catheter 1 and the magnetic layer 8 so as to properly fix the urethral catheter 1 on the soft magnetic patch 2.

The layer of soft magnetic material 3 is laid in the wall layer of the catheter silica wall 11 or outside the catheter silica wall 11 as shown in fig. 1 and 4. The specific setting is subject to actual use.

The width of the magnetic area is 1/3-1/2 of the perimeter of the outer wall of the catheter. The soft magnetic patch is rectangular, the length of the soft magnetic patch is 3-10 cm, and the width of the soft magnetic patch is 0.5-2.5 cm. Improve the fixed effect of catheter 1 through the size of rationally setting up magnetic domain and soft-magnetic paster 2.

The soft magnetic material layer 3 is made of one or more of a magnetic powder core, ferrite or carbonyl iron powder.

The magnetic layer 8 is formed by mixing and tabletting a magnetic material and a thermoplastic material. Or a soft composite material prepared by mixing a magnetic material and a thermosetting material and performing heat treatment processing. The adhesive layer 9 is made of a pressure-sensitive adhesive, and the release film 10 is a film coated with a silicone oil anti-sticking agent.

When in specific use: the soft magnetic patch 2 is attached to the inner side or abdomen of the thigh, the catheter 1 is arranged above the soft magnetic patch 2, magnetic attraction is generated between the catheter 1 and the soft magnetic patch 2, and the catheter 1 can be properly fixed on the soft magnetic patch 2.

The soft magnetic patch 2 can be selectively removed, replaced or continuously used according to the use condition or comfort level of a patient, and the operation is convenient and fast.

When the soft magnetic material layer 3 of the catheter 1 and the soft magnetic patch 2 are in full contact, a pulling force capable of resisting about 1-1.5kg of articles is generated, and the gravity of the catheter 1 and a urine bag and the friction force generated when a daily patient actively and passively moves can be completely borne.

Utilize magnetism to inhale the fixed ureter of attraction replacement traditional adhesive tape or bandage, have following advantage: the catheter is fixed by adopting a traditional adhesive plaster sticking method, if the catheter needs to be replaced or moved to a larger extent or the catheter needs to be nursed, the adhesive plaster needs to be removed, so that the residual adhesive plaster on the skin needs to be removed, and discomfort such as skin injury or pain and the like can be caused when the adhesive plaster is removed; in addition, the residual adhesive trace on the catheter is removed, so that the time and labor are wasted, the catheter is difficult to remove easily, and dirt is very easy to adhere. Adopt magnetism to adsorb fixed approach, catheter itself does not need the adhesive tape fixed, can effectively avoid changing behind the adhesive tape, and remaining viscose adhesion is on the catheter, and the adhesion dirt, the scheduling problem that is pleasing to the eye appears. If the catheter needs to be replaced or pulled out, the urinary catheter only needs to be pulled away from the soft magnetic sheet. The soft magnetic patch can be selectively removed, replaced or continuously used according to the use condition or comfort level of a patient, and the operation is convenient and fast. The soft magnetic patch has large contact area, is not easy to curl or fall off, and has beautiful appearance. When the catheter is adsorbed on the soft magnetic patch, the adsorption force is stable for a long time, and the gravity action of the catheter and the urine bag and the friction force generated when daily patients actively and passively move can be effectively resisted.
