Description

Technical Field

[0001] This utility model relates to the field of catheter fixation technology, and in particular to a catheter fixation device with adjustable diameter. Background Technology

[0002] A urinary catheter is a common indwelling urinary catheterization device. When using it, medical staff need to insert one end of the catheter into the patient's bladder along the urethra, and connect the other end to a urine bag to drain the patient's urine.

[0003] Chinese Patent Publication No. CN 216022616 U discloses a urinary catheter fixation device, comprising a main body, an internal fixation device, and an external fixation device. The internal fixation device is disposed on the main body, and the external fixation device is disposed on the main body. This utility model belongs to the field of urinary catheter fixation technology, specifically referring to a urinary catheter fixation device. During use, the internal fixation device effectively fixes the bladder, while the external fixation device relatively fixes the urinary catheter. This effectively solves the problem that in current clinical practice, urine is discharged from the stoma using an external urinary catheter, and the patient hangs the catheter and the connected urine bag on their body or carries it in their hand. This catheter frequently slips off, easily causing urine leakage or bacterial infection of the stoma wound, causing great pain to the patient and significantly reducing the quality of patient recovery.

[0004] The existing technical solutions described above have the following shortcomings: The technical solutions utilize external fixation devices, which involve tearing off the release paper and attaching it to the thigh with medical tape. While this achieves basic fixation, the muscles at the bottom of the thigh are pressed outwards when the patient sits down, causing the muscles to be squeezed within the fixation device and resulting in discomfort. There is room for optimization, therefore, it is necessary to design an adjustable-diameter catheter fixation device to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a catheter fixation device with an adjustable diameter to solve the problem of discomfort caused by compression of the internal muscles of the fixation device mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a urinary catheter fixing device with adjustable diameter, comprising a fixing ring body, a first combined ring, a second combined ring, and a third combined ring, wherein the fixing ring body is composed of the first combined ring, the second combined ring, and the third combined ring;

[0007] The first, second, and third combined rings are all fixed with an anti-slip layer on their inner sides, and the anti-slip layer has a ventilation groove inside. The first, second, and third combined rings are uniformly provided with first ventilation holes inside. The first, second, and third combined rings are connected by an elastic band, and the elastic band is uniformly provided with second ventilation holes inside. One end of the first, second, and third combined rings is fixed with a medical adhesive tape holder, and the outer side of the medical adhesive tape holder is provided with a limiting groove.

[0008] Preferably, a strap is fixed to one side of the first combination ring, and a first Velcro and a second Velcro are provided on the outer side of the strap, and a connecting ring is fixed to one end of the third combination ring.

[0009] Preferably, the first hook and loop fastener has a hook side and the second hook and loop fastener has a fleece side.

[0010] Preferably, a fixing block is connected to the top of the first combined ring, and fixing grooves are provided on the inner side of the fixing block and the outer side of the first combined ring, and the main body of the catheter is connected inside the fixing groove.

[0011] Preferably, positioning blocks are evenly fixed at both ends of the catheter body, and positioning grooves are provided on the inner side of the fixing blocks and the outer side of the first combined ring, and the positioning grooves are connected to the positioning blocks.

[0012] Preferably, the width of each positioning block matches the width of the positioning groove, and there are four sets of positioning blocks and positioning grooves.

[0013] Preferably, adhesive layers are provided on both sides of the bottom end of the fixing block, and release paper is connected to the bottom end of each adhesive layer.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the adjustable diameter catheter fixing device realizes the functions of easy movement of the fixing device and easy fixation of the catheter to the bottom;

[0015] By designing the main body of the fixation ring into a pattern consisting of a first combination ring, a second combination ring, and a third combination ring, with each combination ring connected by an elastic band, the main body of the fixation ring is fitted onto the outside of the patient's thigh during use. The anti-slip layer inside the combination ring increases the contact friction with the thigh, making it less likely to fall off. The top can be further reinforced by wrapping medical tape around the medical tape adhesive seat. When the patient sits down, the elastic connection between each combination ring can avoid muscle compression, improve overall comfort, and facilitate patient movement.

[0016] By placing the main body of the urinary catheter in the fixing groove inside the first combined ring, and connecting the two sets of positioning blocks at one end of the urinary catheter main body to the positioning groove, then tearing off the release paper inside the fixing block to make it fit against the outside of the first combined ring, and connecting the positioning block at the other end of the urinary catheter main body to the positioning groove inside the fixing block, the main body of the urinary catheter can be quickly fixed and is not easy to fall off.
