The working principle of extension tube mainly includes the following aspects:
Application of pressure extension tube in chest drainage: In chest drainage, the function of extension tube is to discharge liquid or gas in pleural cavity into drainage bottle. When high pressure is formed in pleural cavity, liquid or gas is discharged into drainage bottle through extension tube; when negative pressure is restored in pleural cavity, liquid in drainage bottle is sucked to the lower end of extension tube, forming negative pressure water column, thereby preventing air from entering pleural cavity.
Working principle of GE monitor compatible double-tube blood pressure extension tube: This extension tube is mainly used to monitor blood pressure and electrocardiogram signals. It uses double-tube design, one end is connected to sphygmomanometer, and the other end is connected to patient, which is used to measure arterial blood pressure. A special balloon is installed at the end of extension tube to improve the accuracy of blood pressure monitoring. In addition, the extension tube adopts quick connector connection, which is convenient for medical staff to use, and the surface adopts non-slip design to facilitate patient movement.
Principle of penis enlargement: Penis enlargement is to separate the corpus cavernosum buried in the body by cutting the superficial and deep suspensory ligaments on the penis, and use the suture technique of filling inside and pulling outside to extend the external part of the penis by 3 to 5 cm. This surgery is suitable for cases of short penis and poor development, but the surgery has a high risk and may damage nerves or blood vessels, leading to erectile dysfunction and other problems.
