Description

Wound surface flushing device and flushing method for pre-filled flexible porous catheter Technical Field The invention relates to the technical field of medical care instruments, in particular to a wound surface flushing device and a flushing method of a pre-filled flexible porous catheter. Background The wound surface flushing is an important operation for preventing wound surface infection, removing purulent secretion and promoting wound surface healing in the clinical wound surface nursing and household wound surface dressing change process, and is required to be performed on the diabetic foot, various wound surfaces forming sinus and submerged cavity at present and promote healing in the clinical nursing and household dressing change processes such as diabetic foot, pressure sore nursing and the like. Traditional washing unit adopts ordinary syringe cooperation stereoplasm straight tube to wash the operation more, need the manual work to draw the flushing fluid during the use again to wash the operation, the inconvenient patient of action can't independently accomplish the flushing operation, easily cause the pollution of flushing fluid and apparatus in the operation process, increase the surface of a wound infection risk, and supporting flushing catheter is mostly stereoplasm structure, insert easily fish tail surface of a wound newly-produced granulation tissue and mucosa by force, cause secondary damage and the painful sense of inducing, liquid rivers pressure is concentrated simultaneously, easily cause impact damage to the surface of a wound, and wash the scope limitation, be difficult to carry out comprehensive washing to sinus inner wall and surface of a wound dead angle, result in the secretion to remain, the washing effect is not good. Disclosure of Invention Aiming at the defects of the prior art, the invention provides a wound surface flushing device of a pre-filled flexible porous catheter and a flushing method thereof, which solve the problems that the traditional flushing device is mainly used for flushing operation by adopting a common injector matched with a hard straight tube, flushing operation is needed to be carried out after flushing liquid is manually extracted during use, flushing operation cannot be independently finished by a patient with inconvenient actions, pollution of flushing liquid and instruments is easy to cause in the operation process, the risk of wound surface infection is increased, the matched flushing catheter is of a hard structure, the wound surface granulation tissue and mucous membrane are easily scratched by forced insertion, secondary damage is caused, pain is caused, meanwhile, the pressure of liquid outlet water flow is concentrated, impact damage is easily caused to the wound surface, the flushing range is limited, the inner wall of a sinus tract and dead corners of the wound surface are difficult to comprehensively flush, secretion residues are caused, and the flushing effect is poor. The wound surface flushing device for the pre-filled flexible porous catheter comprises a supporting plate, wherein the bottom of the supporting plate is fixedly connected with a needle cylinder, the bottom of the needle cylinder is fixedly connected with a liquid outlet pipe, the bottom of the liquid outlet pipe is fixedly connected with a soft catheter, one end of the soft catheter, which is far away from the liquid outlet pipe, is fixedly connected with a round guide head, one end of the soft catheter, which is close to the round guide head, is uniformly provided with side holes, the outer wall of one end of the soft catheter, which is close to the round guide head, is provided with a protective cover, and one side of the supporting plate is provided with a supporting component. Through adopting above-mentioned technical scheme, through the cylinder adoption prefilled type design, traditional joining in marriage liquid and drawing liquid step have been saved, patient or family members need not to possess professional nursing knowledge, only need unpack the packing and can use, greatly reduced the threshold of nursing at home, let the surface of a wound wash the nursing become more simple and easy, especially be fit for self-care under the environment at home, the round guide head is when visiting the sinus, can not stab granulation tissue, effectively protect the surface of a wound tissue, the side opening goes out liquid design, liquid is the side direction and sprays the form and flow, the impact pain that the high-pressure direct current water column caused to the surface of a wound bottom is avoided, the comfort level that has promoted patient wash the in-process, and the side direction rivers can more comprehensively, effectively wash pus and necrotic tissue of sinus inner wall, realize more thorough debridement effect, the visor has ensured that the pipe head that contacts the surface of a wound keeps absolute aseptic condition before the deblocking, external bact
