Once you are prepared for the dialysis, A fluid containing salt and different additives is passed into your abdomen via a catheter. This process essentially removes all the waste products from your blood by using the peritoneum layer in your abdomen.

Silicone resuscitator is a simple tool for artificial ventilation. Compared with mouth-to-mouth breathing, it has a higher oxygen supply concentration and is easy to operate. Especially when the patient is in critical condition and there is no time for tracheal intubation, a pressurized mask can be used to directly supply oxygen to the patient, so that the patient can get sufficient oxygen supply and improve tissue hypoxia.

Medical sharps box is a container specially used for safely collecting and disposing of medical waste sharps. Such sharps include needles, surgical blades, glass test tubes, metal sharp objects, etc. Improper handling can easily cause punctures or cuts to medical staff, and even cause infection. Therefore, medical sharps boxes play an important role in the safety management of medical places.

Hypertension is a chronic disease in which blood pressure is continuously elevated, usually referring to abnormally elevated arterial blood pressure. According to the World Health Organization, normal blood pressure for adults should be systolic pressure (high pressure) less than 140 mmHg and diastolic pressure (low pressure) less than 90 mmHg. Exceeding this standard is considered hypertension. Hypertension is often called the "silent killer". Most patients can develop the disease without any symptoms, and long-term higher-than-normal pressure on the blood vessel walls can lead to serious diseases such as coronary heart disease and stroke.

Venous blood collection is to collect blood samples for testing and analysis by inserting a thin tube into the human vein with a needle. Veins are a type of blood vessel in the human body with weak or even no pulse. They are usually located deep in the subcutaneous tissue and muscles, with thick walls, and are less affected by factors such as autonomic nerves and changes in body position, so they are suitable for blood collection. When collecting blood, medical staff will perform multiple steps such as disinfection, puncture, and fixation to ensure the safety and accuracy of blood collection. Venous blood collection is a common medical operation and is widely used in clinical medicine and scientific research.
