1. How to choose the intubation site of central venous catheter? At present, the order of catheter selection recommended by multiple guidelines and the consensus of Chinese experts on vascular access for hemodialysis is right internal jugular vein, left internal jugular vein, right femoral vein, left femoral vein and subclavian vein.
The disposable sterile medical anti-blocking suction drainage tube consists of an inner tube, an outer tube and a suction port, and is provided in a sterile package. It is suitable for the suction and drainage of blood, body fluid and debris from surgical wounds.
1. Prevent catheter from falling off 2, should wear loose low collar or collarless clothes 3, pay attention to wear clothes, take off clothes, turn around the movement range is not too large, do not move too hard, to prevent pulling, touch the catheter or pull out the catheter. 4. Once the catheter falls off, immediately press the wound to stop bleeding for at least 15 minutes. If there is discomfort or bleeding, go to the hospital as soon as possible.
An intravenous catheter is a medical device that is inserted and fixed in a patient's venous channel for the purpose of infusing drugs, rehydration, or monitoring. It is usually made of soft materials, such as plastic or silicone, and is stretchable. Insertion of a venous catheter is usually performed by puncturing a vein or using an instrument called a "guide needle. Once inserted, the catheter is passed through the vein into the body until it reaches the desired location. The catheter's **is then fixed to the skin to ensure it does not move or fall off.
Once worn, the disposable mask can be boiled, sprayed with alcohol, or disinfected with ultraviolet light to disinfect the used mask. In theory, it can eliminate bacteria and viruses that stick to the mask, but these methods can eliminate viruses. In addition, the fibers of the melt-blown non-woven fabric will also be destroyed, thereby reducing the function of the mask.
No matter almost all the staff in the hospital wear masks, its main function is cross infection. It can be said that high-quality disposable sterile masks can not only protect the health of doctors, but also the health of patients.
The masks currently used in hospitals are medical surgical masks, which look thin and comfortable to wear, but they are also divided into three layers: from the outside to the inside are a waterproof layer, a filter layer and a comfort layer. In addition, it also meets the YY0469-2004 "Technical requirements for medical surgical masks" standard. The outermost blue layer is a waterproof layer that prevents blood and saliva from penetrating into the mask. The innermost comfort layer is white and has a moisture-absorbing effect. Don't wear it backwards.
Masks can be divided into two categories: medical/non-medical. As the name suggests, medical masks are mainly used for medical protection and can be divided into three types: medical protection, medical surgery and disposable medical treatment. Non-medical masks, also known as personal protective masks, can be subdivided into anti-accumulation according to their application. Particulate matter and daily protection. Masks for different uses have different technical requirements and different application ranges
Choose the level of protection, and then check the dust in the environment: if there is only harmful gas, the general fuel tank selection can meet the requirements; if it contains dust, the water tank should be integrated. According to the filtration level, the integrated filter can confirm the performance level of the filter dust:
Wu Zunyou, chief expert in epidemiology at the Chinese Center for Disease Control and Prevention, said in response to the question "When do you not need to wear a mask and when do you need to wear a mask?" It is getting hotter and hotter, and everyone is wearing a mask. I have been very concerned, plus some student cases, everyone is more concerned about this issue. In principle, there is no need to wear a mask in a well-ventilated place, as long as the ventilation is good, it should be safe.
