Pulse Lavage Drainage Device is mainly applicable to the flushing of wounds during wound surgery. It is characterized in that the device does not contact the wound, and the washing of different parts is selected by the operator according to the clinical needs. Different flow rates and different liquid flow shapes may be selected. A clear operative vision can be obtained, and the incidence of surgical infection can be reduced; Bone chips, blood clots and fat particles can be removed sufficiently to reduce the incidence of death due to embolism. 

The product is tested by quality supervision and inspection center, and the performance reaches the standard requirements.  The product is clinical trial in domestic famous hospitals, such as Chinese Academy of Medical Sciences & Peking Union Medical College Hospital, Affiliated Hospital of Anhui Medical University and other domestic famous hospitals. The clinical report shows that the overall performance reaches the level of similar foreign products.

Pulse Lavage Drainage Device is used for the washing of the clinical surgical wound and the wound surface, and can effectively prevent infection, inflammation, and reduce wound healing and the like. It is applicable to orthopedics, thoracoabdominal surgery, emergency, gynaecology and so on. And is particularly suitable for cleaning various complex cavities and wall surfaces. The device is characterized in that the device can form a pulse water flow, and the pressure can be adjusted according to the needs, and meanwhile as automatic washing, the device can attract the sewage, reduce the pollution and create a clear view. 

Operating principle: the motor drives the gear to rotate, and the pulse pressure is formed in the piston cavity. Different input power of the motor produces different water pressure, and the flow rate can reach 780ml/min. With different spray heads, different shapes of water flow can be ejected, and can be used for cleaning different parts. 

Can be used for orthopedics: when the joint surgery is performed, the fat particles adhered on the cancellous bone can be removed completely through high-pressure washing, and the fat embolism after operation is reduced. In the total hip or semi-hip replacement surgery of bone cement, the effect of bone trabecula filling in bone cement was increased. Reduces the early loosening of the bone cement fixation prosthesis. Can be used for emergency debridement, can eliminate wound dirt, reduce the occurrence of granuloma, shorten the debridement time and improve the operation efficiency. Can be used for thoracoabdominal surgery, gynaecology, urology and microsurgery, can create a clear field of view in the operation, reduce the visual fatigue of the doctor and improve the operation efficiency. At the same time, the residue after surgery was reduced, and the operation was reduced and issued.

Safety and performance information relevant to the user, or any other person regarding the device:

1.Sterile only if Package is unopened and undamaged. Do not use if the package is damaged.

2.Explosion Hazard. 

3.Do not use in presence of flammable anesthetics or gases. 

4.Do not submerge handle in liquid as this may compromise the efficiency of the pump or alter the PH of the liquid.

5.Warning statement that addresses the HAZARDS that can result from unauthorized modification of the ME EQUIPMENT

6.Don't near active HF SURGICAL EQUIPMENT and the RF shielded room of an ME SYSTEM for magnetic resonance imaging, where the intensity of EM DISTURBANCES is high.

7.Use of this equipment adjacent to or stacked with other equipment should be avoided because it could result in improper operation. If such use is necessary, this equipment and the other equipment should be observed to verify that they are operating normally.

8.Use of accessories, transducers and cables other than those specified or provided by the manufacturer of this equipment could result in increased electromagnetic emissions or decreased electromagnetic immunity of this equipment and result in improper operation.”
