Description

Negative pressure anti-bacteria device for open wound and use method thereof

Technical Field

The invention relates to the technical field of medical instruments, in particular to an open wound negative pressure bacteriostatic device and a using method thereof.

Background

For open wounds, large-area soft tissue defects are often accompanied, if the wound surface cannot be closed as soon as possible, serious infection is caused, the wound surface of a wounded person may not heal for a long time, limb infection occurs, and amputation is required when limb necrosis occurs seriously or even occurs. The traditional debridement treatment method has long treatment course and is easy to cause flap necrosis, and the incidence rate of aggravation of infection is as high as 33 percent. In the conventional wound negative pressure therapy, negative pressure has a good bacteriostatic action, can effectively control infection, promote granulation growth and protect the wound, but the method has some problems, for example, for irregular wounds, complete coverage is difficult, and air leakage is easy; for some dead corners, it is difficult to clean completely. In particular, in the process of flushing and draining the wound surface, necrotic tissues and debris often block the catheter, and at the moment, the whole set of negative pressure drainage device needs to be replaced immediately, otherwise, infection is possibly aggravated. In severe cases, the drainage device needs to be replaced even daily, which also greatly increases the pain and economic burden on the patient. Therefore, a novel negative pressure bacteriostasis device needs to be developed, and the defects of the prior art are overcome.

Disclosure of Invention

In order to solve the defects of the prior art, the invention provides an open wound negative pressure bacteriostasis device and a using method thereof, and the invention provides a basic scheme that:

an open wound negative pressure bacteriostasis device comprises a drainage layer, wherein the drainage layer comprises an upper layer and a lower layer, a plurality of support pillars are fixed between the upper layer and the lower layer, a plurality of liquid inlet pipelines penetrating through the upper layer are arranged in the middle of the upper layer, the middle part of the lower layer is provided with a drainage tube which penetrates through the lower layer, the upper part of the drainage tube is arranged in the liquid inlet pipeline, a negative pressure sucker is fixed at the upper end of the drainage tube, the upper end of the negative pressure sucker is communicated with a liquid outlet pipeline, the free end of the liquid outlet pipeline penetrates through the side wall of the liquid inlet pipeline and is arranged at the outer side, a net bag is arranged inside the liquid outlet pipeline, the upper side of the upper layer and the lower side of the lower layer are both provided with dressings, the dressing of the upper layer wraps the liquid inlet pipeline, and the upper side of the dressing on the upper layer is bonded with a wound surface attaching layer, and the dressing on the lower layer is provided with a communicating hole communicated with the drainage tube.

The principle and the effect of the scheme are as follows: cut out in order to adapt to the wound according to the shape of wound earlier before the use, then all bond dressing in the upper and lower both sides on drainage layer, and cover whole device on the wound completely, later paste the attached layer of surface of a wound on the dressing of drainage layer upside, and glue it on the skin around the wound, then pour into the flush fluid into in the feed liquor pipeline, the flush fluid flows into in the clearance between the upper and lower layer on drainage layer and from the outside outflow, wash inwards from the wound edge, can wash some dead angles of wound, the flush fluid suction tube and follow the drain pipe discharge after the negative pressure sucking disc will use, utilize the string bag large granule to collect the foreign matter.

Further, a pressure relief hole is formed in the side face of the liquid outlet pipeline, and a pressure relief valve is inserted into the pressure relief hole.

When the foreign matter in the string bag is too much, when plugging up the outlet pipe, the flush fluid can't be discharged smoothly, will flush the relief valve to spill over from the pressure release hole, in order to remind medical personnel to hook out the string bag, change.

Further, the communicating hole is in an inverted funnel shape.

The inverted funnel-shaped communicating hole can increase the contact area with the flushing liquid and accelerate the discharge of the flushing liquid.

Furthermore, the connection part of the upper side of the lower layer and the drainage tube is arc-shaped.

Because the inlet channel is vertical setting, so when washing and getting into, can strike drainage layer downside perpendicularly, and the junction is the arcuation, and the impact force when can reducing the flushing fluid flow can also carry out the water conservancy diversion better, makes the flush fluid to even diffusion all around, and the volume of the flush fluid that makes drainage layer edge outflow is roughly the same, guarantees the dynamics of washing to wound edge and dead angle department, and the angle of death also can be washed totally.

The application method of the open wound negative pressure bacteriostatic device comprises the following steps:

s1: clear up the obvious foreign matter and surrounding skin tissue in the wound;

s2: cutting the drainage layer according to the shape of the wound to adapt to the wound;

s3: the lower layer of the drainage layer is pasted with dressing, an opening in the shape of an inverted funnel is formed in the drainage tube, then the dressing is pasted on the upper side of the drainage layer, the liquid inlet pipeline is wrapped, the liquid outlet pipeline is arranged on the upper side of the dressing, and then the whole device is covered on the wound;

s4: a wound surface attaching layer is stuck on the dressing on the upper side of the drainage layer and is stuck on the skin around the wound;

s5: pour into the flush fluid into in the feed liquor pipeline, the flush fluid flows from the outside on drainage layer, from the inside washing in wound edge, later utilizes the flush fluid suction drainage tube after the negative pressure sucking disc will use to discharge from the liquid outlet pipe, utilize the string bag to collect large granule foreign matter.
