Embodiment 1
Please refer to Fig. 1, Fig. 1 is the bladder irrigator structural representation of a kind of anti-resorption of the present invention.A bladder irrigator for anti-resorption, described bladder irrigator comprises syringe pipe 1, flushing liquor sacculus 2, rubber pneumatic bag 3; Described rubber pneumatic bag 3 is provided with projection; Described projection and rubber pneumatic bag 3 are Integratively formed; Described rubber pneumatic bag 3 is provided with rubber adapter 31; Described flushing liquor sacculus 2 is Dual-chamber saccular, and flushing liquor sacculus 2 is in 8-shaped; Described flushing liquor sacculus 2 is provided with the first adapter 21 and the second adapter 22, and described first adapter 21 and the second adapter 22 angle are 90 degree; Described first adapter 21 connects with syringe pipe 1; Described syringe pipe 1 one end connects silica gel valve 12, and the other end connects flush-through connection 11; Described silica gel valve 12 is entrenched in the end of the first adapter 21; Described second adapter 22 connects with rubber adapter 31; The first described adapter 21 and the second adapter 22 are all connected to the side bottom flushing liquor sacculus 2; Described syringe pipe 1, flushing liquor sacculus 2, rubber pneumatic bag 3 be hollow structure, its inner passage communicates.
Please refer to Fig. 2, Fig. 2 is silica gel valve door schematic diagram.Described silica gel valve 12 is in infundibulate, and silica gel valve 12 large end face and syringe pipe 1 connect, and silica gel valve 12 small end face is placed in the first adapter 21; In enclosed construction under described silica gel valve 12 small end face naturalness: described silica gel valve 12 is made up of flap 14, and its flap 14 is polymerized to a bit; Described flap 14 is provided with drainage screen 13, and its drainage screen 13 quantity is at least one; Described drainage screen 14 Mesh Diameter be less than bladder or prostata tissue diameter, make bladder or prostata tissue not by drainage screen 14.
It should be noted that: it is transparent material that described flush-through connection 11, syringe pipe 1, silica gel valve 12, first connection tube 21, flushing liquor sacculus 2, second connection tube 22, rubber pneumatic bag 3, rubber adapter 31 are Integratively formed described flushing liquor sacculus 2, for splendid attire flushing liquor in flushing liquor sacculus 2, its flushing liquor can select normal saline, by transparent flushing liquor sacculus 2, can distinguish the flowing property of flushing liquor and to be trapped in tissue mass in flushing liquor sacculus 2 how many, whether assist physician is differentiated abundant to bladder irrigation; Described rubber pneumatic bag 3 is provided with projection, increases staff frictional force, has anti-skidding effect and is convenient to extrude rubber pneumatic bag 3;
Under described silica gel valve 12 closure state, one end is cylindrical, the other end is polymerized to a bit in infundibulate, when silica gel valve 12 two ends air pressure is uneven, flap 14 can opened, and the air pressure of silica gel valve 12 cylindrical end face is when being greater than the air pressure of infundibulate end face, in opened condition, other situation flap 14 is closed condition to flap 14, the closure state of described silica gel valve 12 is controlled by gas pressure power, when with hands extruding rubber pneumatic bag 3, body segment reduces, and connects pressure, air pressure is increased to air, namely the air pressure of silica gel valve 12 small end face is greater than the air pressure of silica gel valve 12 large end face, its gas pressure is at the funnel edge of silica gel valve 12, and valve is closure state, and the liquid in flushing liquor sacculus 2 enters from drainage screen 13, enter bladder through syringe pipe 1, bladder is rinsed, rubber pneumatic bag 3 has elastic reaction, when rubber pneumatic bag 3 is not by staff active force, rubber pneumatic bag 3 recovers shape, body segment increases, the air pressure of silica gel valve 12 small end face is caused to be less than the air pressure of silica gel valve 12 large end face, flap 14 in silica gel valve 12 is opened, flushing liquor simultaneously in bladder and bladder or prostata tissue enter into flushing liquor sacculus 2 through silica gel valve 12, after the air pressure balance of silica gel valve 12 two ends, the flap 14 of silica gel valve 12 is in closed condition, now flushing liquor sacculus 2 is containing bladder or prostata tissue, when again extruding flushing liquor sacculus 2 with hands, silica gel valve 12 is in closure state, its flushing liquor enters bladder from the drainage screen 13 silica gel valve 12 through syringe pipe 1, continue to rinse bladder, and in flushing liquor sacculus 2 under bladder body or the effect of prostata tissue because of drainage screen 13, then can not enter in bladder, effectively prevent from sucking out bladder or prostata tissue enters in bladder, so repeatedly rinse, can intravesical bladder body or the abundant sucking-off of prostata tissue, shorten operating time,
Described rubber pneumatic bag 3 provides power resources, rubber pneumatic bag 3 made of soft, and has elasticity; Described silica gel valve 12 is made up of at least two pieces of flaps 14, and flap 14 has elasticity, enclosed construction under naturalness, liquid not by;
Described flush-through connection 11 connects for the catheter of drawing from bladder, described drainage screen 13 forms for filament materials weaves, drainage screen 13 is in concave inward structure, save the space of silica gel valve 12 in the first adapter 21, flushing liquor good fluidity, and flushing liquor in bladder is when flowing in flushing liquor sacculus 2, flushing liquor flows out through drainage screen 13 simultaneously, and then the prostate gland of absorption on drainage screen 13 or bladder body are back in flushing liquor sacculus 2, like this, the prostate that drainage screen 13 does not just adsorb or bladder body, therefore, when flushing liquor in flushing liquor sacculus 2 enters in bladder through filter screen 13 again, flushing liquor good fluidity,
Described flushing liquor sacculus 2 is in double cavity structure, flushing liquor is made to have storage area, simultaneously for bladder or prostata tissue provide storage area, because bladder or prostata tissue are because self having the effect of gravity, when flushing liquor sacculus 2, can be deposited in the bottom at flushing liquor sacculus 2, when avoiding flushing liquor to reflux, subsidiary more bladder or prostata tissue are back to drainage screen 13 place;
The first described adapter 21 and the second adapter 22 are in 90 degree of designs, and one side caters to the position in art, makes easy to operate, on the other hand, increases surgical field of view in being conducive to.
