Description

A multifunctional disposable negative pressure drainage device

technical field

The utility model relates to the technical field of medical equipment, in particular to a multifunctional disposable negative pressure drainage device.

Background technique

Drainage is one of the most commonly used and most important basic techniques in surgery. It refers to the drainage of fluids in body cavities, joint cavities, organs or tissues, including blood, pus, inflammatory exudate, bile, secretions or cystic fluid, etc. Lead out of the body (external drainage) or in vivo (internal drainage), so as to prevent or treat damage to the body due to effusion. Proper use of drainage can prevent infection or spread of infection and reduce complications. The disposable negative pressure drainage ball is one of the most commonly used drainage devices clinically, and it consists of three parts of silicone products, a balloon, a catheter and a drainage tube. Through the extracorporeal catheter, one end is connected to the internal drainage tube, and the other end is connected to the negative pressure ball. The connecting end to the extracorporeal connecting tube is equipped with a one-way valve, and the other end is an exhaust hole with a closed airtight plug cap. Compression of this ball creates a continuous negative pressure. Its function is to expel secretions, blood, exudates, foreign bodies, etc. in the wound or cavity. Although it is simple in structure and easy to use, it still has many defects and deficiencies.

Specifically, in order to ensure the drainage effect and continue to expel secretions, blood, exudates, foreign bodies, etc. in the wound or cavity, medical personnel need to obtain negative pressure by squeezing the balloon, which is currently used in clinical practice. The single-use negative pressure drainage ball is based on the experience of medical staff to squeeze the balloon to obtain negative pressure. The size of the negative pressure is often not easy to determine, precise control cannot be achieved, and the drainage effect cannot be clearly defined; on the other hand, all surgical drainage must According to the color, nature and volume of the drainage fluid, the outcome of the patient's condition can be judged, so that the patient's condition can be diagnosed and treated in a timely manner. At present, the routinely used disposable negative pressure drainage ball, when the nurse observes the amount of drainage fluid in real time, needs to open the cover at the end of the balloon, use a syringe or a measuring cup to measure the amount of drainage fluid in it, and observe the color and nature of the drainage fluid at the same time , especially for critically ill or complicated surgical patients, the operation may be performed dozens of times a day. This will increase the risk of accidental detachment of the patient, the risk of infection and the occurrence of complications, and reduce the success rate of the operation; it will also increase the physical and mental pain of the patient and their family members.
