DETAILED DESCRIPTION

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0023] like Figure 1-6 As shown, the irrigation aspirator mainly includes an irrigation aspirator body 1, a two-way valve body 2, a suction pump port 3 and a water inlet port 4.

[0024] The interior of the flushing aspirator body 1 is hollow, and one end (set as the front end and the other end as the rear end) has a front passage 11, and the rear end has two rear passages 12 extending side by side, and the front and rear ends of the flushing aspirator body 1 are connected.

[0025] Preferably, a flushing nozzle 5 may be installed at the end of the front passage 11 of the flushing aspirator body 1 for flushing work, wherein the flushing nozzle 5 is detachable.

[0026] The two-way valve body 2 is installed on the rear end of the irrigation aspirator body 1 , wherein the two-way valve body 2 has two independent chambers 26 , and the two rear passages 12 of the irrigation aspirator body 1 pass through the two chambers 26 side by side.

[0027] A suction shut-off valve 21 and a waterway shut-off valve 22 are movably mounted side by side on the two-way valve body 2, wherein the suction shut-off valve 21 and the waterway shut-off valve 22 are both movably mounted and can be raised and lowered on the two-way valve body 2 when subjected to force.

[0028] The bottom of the suction cut-off valve 21 and the water cut-off valve 22 are respectively connected with two lifting blocks 24, and the two lifting blocks 24 extend into the two chambers 26 from above; and the two lifting blocks 24 are respectively provided with two through-holes 25, and the two through-holes 25 can be respectively connected with the two rear passages 12. The two through-holes 25 have different heights, specifically, the height of the through-hole 25 on the suction cut-off valve 21 is lower than the through-hole 25 on the water cut-off valve 22, and at most only one through-hole 25 can be connected with the corresponding passage at the same time.

[0029] A state switching key 23 is installed at the top of the suction shut-off valve 21 and the water shut-off valve 22. By operating the state switching key 23, the suction shut-off valve 21 and the water shut-off valve 22 can be pressed or raised at the same time.

[0030] Preferably, one end of the state switch key 23 is installed on the top of the suction shut-off valve 21 and the water circuit shut-off valve 22, and the other end is connected to the outside of the rear end of the flushing suction device body 1 through a clamp block 6, and a buckle 61 is provided on the outside of the rear end of the flushing suction device body 1, and the clamp block 6 is connected to the buckle 61, then the clamp block 6 and the buckle 61 can limit the other end of the state switch key 23, thereby maintaining the stability of the entire state switch key 23.

[0031] In addition, when the state switching key 23 is in the natural state, the port 25 on the suction shut-off valve 21 is connected to the corresponding rear passage 12, and due to the different heights, the port 25 on the water shut-off valve 22 is not connected to the corresponding rear passage 12. This state can be used for liquid suction work.

[0032] The state switching key 23 is also provided with a suction control port 7, which is connected to the port 25 on the suction cut-off valve 21. When the port 25 on the suction cut-off valve 21 is connected to the corresponding rear passage 12 to perform liquid suction, the suction force during liquid suction can be controlled by covering the area of ​​the suction control port 7.

[0036] At this time, the front passage 11 port of the irrigation suction device body 1 is aligned with the wound surface, and the negative pressure suction device is turned on. The suction force generated can suck the body fluid from the wound surface through the irrigation suction device body 1 (the flow direction of the body fluid is as follows). Figure 4 The flushing aspirator can be held in one hand, and a finger can be used to cover the area of ​​the suction control port 7 to control the suction force during aspiration.

[0037] like Figure 5-6As shown, when the flushing device is used for flushing, the flushing nozzle 5 is installed at the end of the front passage 11 of the flushing suction device body 1, and the state switching key 23 is pressed to make the port 25 on the water circuit shut-off valve 22 drop to be connected with the corresponding rear passage 12, and at the same time, the port 25 on the suction shut-off valve 21 is disconnected from the corresponding rear passage 12, so that the front passage 11 of the flushing suction device body 1 is connected to the rear passage 12, and at the same time, the rear passage 12 is connected to the equipment providing the flushing water source through the water inlet port 4.

[0038] At this time, aim the flushing nozzle 5 at the area to be flushed, and pass the flushing water into the flushing nozzle 5 through the flushing aspirator body 1 (the water flow direction is as follows). Figure 6 The designated area can be rinsed as shown in the dashed line and arrow in the middle). The rinse aspirator can also be held in one hand, and the state switching key 23 can also be pressed with one finger, thereby achieving the control operation of the rinse aspirator with one hand.

[0039] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
