Description

A drape for central venous catheter maintenance

technical field

The utility model relates to a medical device, in particular to a drape for central venous catheter maintenance.

Background technique

With the development of medical science, central venous catheters: PICC, CVC and infusion ports are more and more accepted by patients, and more and more patients are placed with catheters. The central venous catheter is placed in the patient's vein for a long time, which greatly increases the risk of wound infection. In order to prevent venous infection and inflammation, the central venous catheter must be maintained, cleaned and disinfected in daily care. Since there is no special drape for catheter maintenance, disposable treatment towels are often used in the daily nursing process, and the nursing staff lacks a uniform standard for operation. During the maintenance of central venous catheters, operational errors are often made, leading to patient infection and doctor-patient disputes.

After the introduction of WS/T 433-2013 "Nursing Technical Specifications for Intravenous Therapy", the nursing work of central venous catheters has certain theoretical guidance, but there is still a lack of special drape for catheter maintenance. The main problems in clinical work are as follows:

1. At present, in clinical catheter maintenance, a disposable treatment towel is placed under the arm of the catheter side, and then disinfected. Because the wound surface is not well protected, it is often infected by clothing, hair and speech saliva. At the same time, unsterilized arms and palms are also exposed to the drape, which also poses a risk of infection, which does not meet the requirements for nosocomial infection management.

2. During the maintenance of the central venous catheter, due to the removal of the fixing device during disinfection, the central venous catheter slides left and right, and the catheter is easily taken out of the body. There is a risk of catheter prolapse, and phlebitis is prone to occur.

3. Risk of puncture injury from sharp objects. When doing catheter maintenance in front of the hospital bed, sharps such as needles need to be placed in a special sharps box, and it is inconvenient for nurses to carry the sharps box. During the operation, the storage point of sharps is not easy to control, posing safety hazards .

4. When doing catheter maintenance in front of the hospital bed, it is inconvenient to place the used medical supplies. You need to bring yellow garbage bags, which will increase the amount of supplies prepared.

Searching the patent literature related to drape has not found a special drape for central venous catheter maintenance, and there is no special drape for sale in the market. It is necessary to develop a drape product dedicated to central venous catheter maintenance.
