Embodiment 1

[0041] Please refer to figure 1 , figure 1 It is a structural schematic diagram of an anti-retraction bladder irrigator of the present invention. An anti-resistance bladder irrigator, the bladder irrigator includes a flushing tube 1, a flushing liquid balloon 2, and a rubber airbag 3; the rubber airbag 3 is provided with a protrusion; the protrusion and the rubber airbag 3 are once integrally formed; the rubber airbag 3 is provided with a rubber joint 31; the flushing fluid balloon 2 is a double-chamber balloon, and the flushing fluid balloon 2 is in the shape of a figure 8; the flushing fluid balloon 2 is provided with a first Connecting pipe 21 and second connecting pipe 22, the angle between the first connecting pipe 21 and the second connecting pipe 22 is 90 degrees; the first connecting pipe 21 is connected to the flushing pipe 1; one end of the flushing pipe 1 is connected to the silicone valve 12, The other end is connected to the flushing joint 11; the silicone valve...

Embodiment 2

[0050] Please refer to image 3 and Figure 4 , image 3 It is a structural schematic diagram of another anti-retraction bladder irrigator of the present invention. Figure 4 It is another structural schematic diagram of the silicone valve. This embodiment is basically the same as Embodiment 1, except that the filter screen 13 of this embodiment is an outwardly convex structure, which is suitable for the bladder tissue in the flushing liquid balloon 2 in urological operations with more bladder or prostate tissue. It will not be adsorbed on the filter screen 13 to affect the flushing liquid entering the bladder.

Embodiment 3

[0052] Please refer to Figure 5 and Figure 6 , Figure 5 It is a structural schematic diagram of another anti-retraction bladder irrigator of the present invention. Figure 6 It is another structural schematic diagram of the silicone valve. This embodiment is basically the same as Embodiment 1, except that the filter screen 13 on the silica gel valve 12 of this implementation is inwardly concave and outwardly convex, making up for the filter screen 13 being concave inward or outwardly alone. Insufficient concave, according to specific surgical needs to choose.

Abstract

The invention relates to a back-suction preventive bladder irrigator, comprising an irrigating tube, an irrigating liquid balloon and a rubber balloon. The rubber balloon is provided with protrusions formed integrally with the rubber balloon. The rubber balloon is provided with a rubber connecting tube. The irrigating liquid balloon is provided with a first connecting tube and a second connecting tube. The first connecting tube is connected with the irrigating tube. One end of the irrigating tube is connected with a silicone valve, and the other end thereof is connected with an irrigating connector. The silicone valve is funnel shaped, a large end face of the silicone valve is connected with the irrigating tube, and a small end face of the silicone valve is disposed in the first connecting tube. The silicone valve is composed of a valve flap which is provided with a strainer. The strainer is inwardly concave or outwardly convex. The back-suction preventive bladder irrigator has the advantages that the cost is low, the irrigator is handy, disposable and tolerant to high-temperature sterilizing and is suitable for fully irrigating the bladder, prostate or bladder tissues are avoided being sucked back into the bladder, the surgical time is shortened, surgical risk is decreased, and the irrigator has a promising clinical application prospect.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an anti-retraction bladder irrigator. Background technique [0002] In urology, the prostate or bladder tissue removed after transurethral endoscopic prostate and bladder surgery needs to be flushed during the operation, and a large amount of normal saline is flushed to discharge the prostate or bladder tissue. The corresponding bladder flushing The device is a bladder irrigator. [0003] The common structure of existing bladder irrigator is made up of irrigation tube, irrigation liquid balloon and rubber air bag. When the rubber balloon is squeezed, the flushing liquid in the flushing liquid balloon enters the bladder through the flushing tube to flush the bladder. Prostate tissue or bladder tissue, etc., as the rubber balloon is squeezed again, the prostate tissue or bladder tissue enters the bladder again, and the suction of the tissue is insufficient, which prolongs...
