Detailed Description
The wound negative pressure irrigation device of the present application is described in detail below with reference to the accompanying drawings.
The application discloses wound negative pressure washing unit, it includes: a tube 10, a first cover 11, a bottle 20, and a second cover 21.
The tube 10 is intended to be inserted into a wound; the pipe body 10 includes an inner pipe and an outer pipe concentrically arranged with a predetermined interval space formed therebetween; a plurality of through holes are formed at the lower part of the inner pipe, so that the inner part of the inner pipe is communicated with the space between the inner pipe and the outer pipe; the inner pipe is formed with many bracing pieces between the outer pipe, from this inner pipe and outer union coupling are as an organic whole.
A first cover 11 detachably covering the upper end of the pipe 10; a mounting hole 17 is formed in the middle of the first cover body 11 and used for mounting the silica gel plug 15; the silica gel plug 15 is formed into a horn shape, a water inlet pipe jack is formed in the middle of the silica gel plug, a water inlet pipe 16 is inserted into the water inlet pipe jack, and the lower end of the silica gel plug extends to the lower end in the pipe body 10; the upper end of the water inlet pipe 16 is used for introducing flushing liquid; the lower end of the water inlet pipe 16 is closed, and a plurality of fine holes from which the irrigation liquid is sprayed to irrigate the wound are formed at the closed end.
The bottle body 20 is used for containing flushing waste liquid; a second cap 21 is detachably mounted on the upper end of the bottle body 20; a negative pressure source pipe 22 is formed on the second cover body 21; the negative pressure source pipe 22 is used for connecting with a negative pressure source; a bridging pipe 23 is connected between the second cover body 21 and the first cover body 11; the first end of the bridge pipe 23 is connected to the second cap 21, and the second end of the bridge pipe 23 is connected to the first cap 11 and faces the space between the inner pipe and the outer pipe, so that negative pressure is generated in the space, and the waste flushing liquid in the inner pipe is sucked into the inner pipe through the through hole at the lower part of the inner pipe and then flows into the bottle body 20 through the bridge pipe 23.
A silica gel ring 13 is arranged on the periphery of the tube body 10, and the silica gel ring 13 is used for covering the skin around the outer side of the wound; the medical adhesive is formed on the lower side of the silica gel ring 13, so that the silica gel ring 13 is adhered to the skin around the outer side of the wound, and the washing waste liquid is prevented from leaking outwards.
A flange 12 is formed on the outer circumference of the tube 10 to define the position of the first cover 11 on the tube 10.
The lower end of the outer pipe is also provided with a plurality of through holes; and the lower end of the outer tube is further coated with a porous material 14 (for example, a foam material with a pore size of 400-.
When in use, the tube body 10 is inserted into the wound, and the silica gel ring is well adhered along the skin around the wound; the water inlet pipe is connected with flushing liquid, the negative pressure pipe is connected with a negative pressure source (such as a negative pressure suction source provided on the wall in a ward) so that negative pressure is generated in the bottle body, and the negative pressure of the bottle body passes through the bridging pipe so that negative pressure is also generated in a spacing space between the inner pipe and the outer pipe; thus, the cleaning liquid sprayed from the lower end of the water inlet pipe cleans the surface of the wound, enters the space between the inner pipe and the outer pipe through the through hole of the inner pipe, and is sucked into the bottle body by the bridging pipe right above the space.
