The present disclosure provides a balloon-free, self-retainable and threadable urethral catheter that contains special external markings to guide insertion, and that could be indwelled easily and safely. Through various experiments and the structural configuration, the balloon-free, self-retainable and threadable urethral catheter of the present disclosure can make insertion of a mushroom-tip urethral catheter easily performed by primary care medical professionals, instead of previously only been done by senior urologists with a semi-rigid stainless-steel stylet. This disclosure leads to better urine drainage and reduces irritation to the posterior wall of the bladder. With the special design of this disclosure, minor urethral structure can be overcome to insert this catheter safely.

A catheter having at least one small hole shaped to reduce urethral trauma at the proximal insertion end of the catheter.

The utility model belongs to the fixed paste technical field, specifically is a catheter secondary fixed paste, including fixed paste main part, the middle part of fixed paste main part is provided with transparent dressing, both sides of transparent dressing are provided with adhesive plaster, the middle part of transparent dressing front is provided with fixed pad, both sides of fixed pad are provided with bandage. The utility model, through transparent dressing and adhesive plaster paste on the patient's skin, place the catheter on the fixed pad, use the bandage to bundle and fix, place the catheter in the catheter groove, pass through the right side fixed hole through the left side anti -disengagement zone, use magic paste stick part and magic paste stick part to stick, the secondary fixed of catheter, cooperate through adhesive tape, bandage and anti -disengagement zone, can more firmly fixed catheter, prevent its displacement or fall off, and long -term use fixed paste, also can not cause the damage of patient.

The application discloses a urinary catheter anti-falling alarm device for urology department, and relates to the technical field of urology department clinical medical equipment.The device comprises an elastic restraint belt, a fixing assembly, a urinary catheter connection monitoring assembly and a monitoring alarm system.The elastic restraint belt is used for fixing the urinary catheter anti-falling alarm device on the surface of a patient.The fixing assembly is in sliding connection with the elastic restraint belt.The urinary catheter connection monitoring assembly is arranged on one side of the top of the fixing assembly.The monitoring alarm system is arranged in the fixing assembly.The device solves the core problems of poor fixing effect and high falling risk of traditional urinary catheters, improves the efficiency of medical staff through simplified operation and optimized data management, and takes into account the comfort and safety of patients, thereby reducing the incidence of complications such as urinary system infection and urethral injury, reducing the workload of medical staff, improving the experience of patients in diagnosis and treatment, and having obvious clinical value.The device can be widely applied to urology department, geriatric department, intensive care unit (ICU) and other scenes, and has high popularization potential and social and economic benefits.

The present disclosure relates to obtaining Foley catheters and double-J catheters that exhibit antibacterial properties and prevent stone formation by means of coating the surfaces of urinary catheters used in the healthcare sector with multiple film layers comprising groups containing gallic acid so as to impart antibacterial properties and stone-formation-preventing effectiveness. It is intended in particular to prevent the ascending transmission of bacteria from the female or male genital region to the bladder with the aid of the catheter during urethral catheter insertion, as well as stone formation due to stasis arising from the slowing of flow and turbulent flow associated with ureteral stents inserted in cases of stricture. It is also intended to prevent the occurrence of damage that may form in the urinary tract due to oxidative stress and inflammation triggered either by infection in the surrounding tissues or by mechanical pressure caused by the stone. Effectiveness is achieved by coating the surfaces of the catheters / stents applied to the urinary tract with film layers of gallic acid, which is effective in all the aforementioned adverse conditions in preventing stone formation and is effective against infectious agents, and which has antioxidant and anti-inflammatory effects.

The utility model belongs to a kind of table body catheter fixer;Including adhesive sheet, one side of adhesive sheet is adhesive layer, the other side is provided with support sheet, the edge of adhesive sheet extends outward relative to support sheet, two fixed clamps are provided on support sheet, seat is provided between two fixed clamps, two movable clamps are connected on seat, one fixed clamp and one movable clamp constitute a pipe clamp, two fixed clamps and two movable clamps constitute the pipe clamp of the main pipe and branch pipe of fixed catheter, seat can drive movable clamp to approach or away from fixed clamp, so that pipe clamp is in clamping state or release state;Through two adjustable pipe clamps, main pipe and branch pipe of catheter can be clamped simultaneously, realize multi-point fixing, effectively prevent catheter displacement or drop‌;The clamping / release state switching of pipe clamp simplifies the installation and disassembly process of catheter, facilitate medical staff quick operation, simultaneously reduce the demand of frequent replacement of adhesive tape‌.

A urethral catheter product (10) comprising a sleeve (22) having a proximal end (24) and a distal end (26), wherein the sleeve defines a sleeve cavity (21). A catheter tube (12) is at least partially located within the sleeve cavity. An insertion aid (28) is associated with the proximal end of the sleeve. The insertion aid has an insertion tip (30), a grommet (32), and a lumen (29) for receiving the catheter tube. The grommet is located within the sleeve cavity, and the insertion tip is outside the sleeve cavity, with the grommet and the insertion tip fitting together.
