How does Medical TPU Tube play a key role in the treatment and care of urinary system diseases? ​

The material properties of medical TPU tubes lay the foundation for applications ​
Medical TPU = a polymer material tailored for medical scenarios. Its special molecular structure gives Medical TPU Tube excellent performance. It is composed of a linear block polymer composed of soft segments and hard segments. The soft segments give the material a soft texture and elasticity, enabling it to adapt to the complex physiological structure of the human urinary system and reduce pressure and damage to tissues; the hard segments form physical cross-linking points through hydrogen bonds, allowing the catheter to have good elastic recovery performance, not easy to deform during use, and always maintain a stable shape and function. ​
In terms of the chemical composition of the material, the diisocyanate, oligomer polyol and chain extender selected for the preparation of medical polyurethane elastomers have been carefully screened and proportioned, making the medical TPU tube have excellent biocompatibility. This biocompatibility means that when the catheter comes into contact with human tissues and cells, it will not easily cause allergic reactions and rejection reactions, greatly reducing the risk of complications caused by the use of catheters, and providing safety guarantees for its long-term use in the treatment and care of urinary system diseases. At the same time, the good chemical stability enables the medical TPU tube to withstand the effects of common disinfectants and detergents. During the daily cleaning and disinfection of medical devices, it can still maintain its own stable performance and ensure the safety and effectiveness of repeated use. ​
TPU catheter effectively solves the problem of urination disorders​
For patients who are unable to urinate independently due to various reasons, urine retention is a serious health threat. Long-term urine retention can cause the bladder to be overfilled, the pressure to increase, and urine to flow back to the kidneys, which in turn causes hydronephrosis and damages kidney function. In addition, urine retention in the bladder also provides a breeding ground for bacteria, which is easy to cause urinary tract infections, and in severe cases may develop into more serious infectious diseases such as pyelonephritis. ​
The emergence of TPU catheters has brought an effective solution for such patients. It can be smoothly inserted into the bladder through the urethra, and urine can be drained out of the body in time, so that the bladder is kept within a reasonable capacity range, avoiding damage to organs such as the kidneys due to urine retention. The soft and elastic characteristics of the TPU catheter make it less irritating to the urethral mucosa during insertion, reducing the discomfort and risk of urethral injury during insertion. In addition, its surface is relatively smooth, which can reduce the chance of bacterial attachment and breeding, and to a certain extent reduce the incidence of urinary tract infection. ​
In actual clinical applications, patients with different types of urinary system diseases can benefit from the use of TPU catheters. For example, patients with neurogenic bladder caused by neurological diseases cannot control the urination function of the bladder normally due to impaired nerve regulation function. TPU catheters can be used as long-term urine drainage tools to help patients maintain the normal physiological state of the urinary system; patients with urethral obstruction caused by prostatic hyperplasia can also use TPU catheters to relieve the symptoms of dysuria and improve their quality of life before or while waiting for treatment.​
TPU catheter creates favorable conditions for urinary system surgery​
In urinary system surgery, clear surgical field of view and sufficient operating space are key factors to ensure the smooth progress of the operation. Inserting a TPU catheter before surgery can keep the bladder empty and avoid squeezing surrounding tissues and organs due to bladder filling, which affects the surgical operation. Doctors can observe the anatomical structure of the surgical site more clearly, perform tissue separation and resection more accurately, reduce the risk of damaging important surrounding structures during surgery, and improve the success rate of surgery. ​
For some surgeries involving the bladder or urethra, TPU catheters can also be used as a guide and support tool for surgical operations. For example, in bladder tumor transurethral resection, the catheter can help doctors determine the location and range of tumors in the bladder, while maintaining the circulation of fluid in the bladder, promptly taking away the heat and tissue debris generated during the operation, and avoiding excessive tissue damage and bleeding. In urethral stricture repair surgery, the catheter can be used as a stent to guide surgical instruments to accurately reach the stricture site, and play a role in supporting the urethra and preventing stricture recurrence after surgery.​
The existence of TPU catheters can also facilitate doctors to observe the color and properties of urine during surgery. Through the changes in urine, doctors can promptly determine whether there are abnormal conditions such as bleeding and infection at the surgical site, so as to quickly take appropriate treatment measures to ensure the safety and effectiveness of the operation. ​
TPU catheters provide an important basis for disease monitoring ​

Accurately monitoring the patient's urine volume is an important means to evaluate renal function, fluid balance and disease changes. During the treatment of urinary system diseases, changes in urine volume can reflect the filtration function of the kidneys, the body's fluid metabolism and the development trend of the disease. TPU catheters can directly collect the patient's urine, and medical staff can obtain rich disease information by observing and measuring the amount, color and properties of urine in the catheter. ​
For example, a sudden decrease in urine volume may indicate problems such as insufficient renal perfusion and renal failure; darkening of urine color and hematuria may mean bleeding in the urinary system; turbidity and odor in urine may indicate a urinary tract infection. By analyzing and judging this information, doctors can adjust the treatment plan in time and take targeted treatment measures. For patients receiving intravenous infusion therapy, by monitoring the amount of urine drawn from the TPU catheter, doctors can assess the patient's fluid balance and reasonably adjust the speed and amount of infusion to avoid excessive or insufficient fluids causing adverse effects on the patient's body. ​
During the patient's recovery process, the TPU catheter also plays an important monitoring role. As the condition improves, the patient's urine volume and urine characteristics will gradually return to normal. By continuously observing the urine collected by the catheter, medical staff can accurately judge the patient's recovery progress, determine the appropriate time to remove the catheter, and promote the patient's early recovery. ​
