[0020] In order to make the purpose, technical scheme and advantages of the utility model more clear, the utility model is further described in detail below with examples. It should be understood that the specific examples described herein are only used to explain the utility model and not to limit the utility model.
[0021] REFERENCE Figures 1-6 The embodiment provides a negative pressure aspirator with smoke suction function for open operation, which comprises a negative pressure pipe 1, a connecting pipe 2, a suction pipe 3, a sleeve 4 and a smoke suction pipe 5. One end of the connecting pipe 2 is connected to the negative pressure pipe 1, and the other end of the connecting pipe 2 is connected to the suction pipe 3. The end of the suction pipe 3 away from the connecting pipe 2 is a suction port 6. The sleeve 4 can be sleeved outside the suction pipe 3. The inner wall diameter of the end of the sleeve 4 close to the connecting pipe 2 is the same as the outer wall diameter of the connecting pipe 2, and the sleeve 4 can be connected to the surface of the connecting pipe 2. A plurality of round holes 7 are arranged on the inner wall of the sleeve 4. A smoke suction cavity 8 is arranged inside the inner wall of the suction pipe 3. One end of the smoke suction pipe 5 is communicated with the inside of the smoke suction cavity 8, and the other end of the smoke suction pipe 5 is communicated with the negative pressure pipe 1. A smoke suction port 9 is arranged on the smoke suction cavity 8 and communicated with the outside of the suction pipe 3. An arc plate 10 is arranged inside the smoke suction cavity 8. The arc plate 10 can move inside the smoke suction cavity 8. A through channel 11 is arranged on the arc plate 10 and corresponds to the smoke suction port 9. A through hole 12 is arranged on the arc plate 10. A square through hole 13 is arranged on the suction pipe 3 and communicated with the inside of the smoke suction cavity 8. An auxiliary block 14 is arranged on the arc plate 10 and can move inside the square through hole 13. The position of the arc plate 10 can be moved by manually moving the auxiliary block 14, so that the smoke suction port 9 and the through channel 11 are communicated.
[0022] The number of the smoke suction ports 9 is at least two, which increases the smoke suction range and improves the smoke suction effect.
[0023] A notch is arranged on the sleeve 4 and matched with the smoke suction pipe 5. When the sleeve 4 is sleeved, the notch can avoid the smoke suction pipe 5 from being blocked, so that the sleeve 4 can be normally connected to the connecting pipe 2.
[0024] The number of the through holes 12 is two, which ensures the smoke suction effect.
[0025] A vent hole 15 is arranged on the smoke suction cavity 8 and communicated with the outside. The vent hole 15 can avoid the smoke suction cavity 8 from forming a closed space when the smoke suction port 9 is closed, so that the suction effect of the suction machine is not affected.
[0026] The utility model discloses when using, connect the suction machine with negative pressure pipe 1, and the air outlet end of suction machine can connect negative pressure suction bottle or other receiving bottle, and can increase filter brine or other filter liquid in receiving bottle according to actual conditions, the negative pressure of negative pressure pipe 1 is produced through suction machine, and the blood water and pus produced in the course of laparotomy are inhaled through the suction port 6 of suction pipe 3, because the suction pipe 3 end is smaller, when producing larger smoke range, the suction effect of suction pipe 3 is not good, can manually pull the auxiliary block 14, and the arc plate 10 moves, and makes the suction port 9, the through channel 11, the through hole 12, the suction pipe 5, the negative pressure pipe 1 intercommunication, and the smoke range is enlarged through increasing suction port 9, and the smoke effect is improved, because suction pipe 3 is generally handheld when using, and it is also more convenient to control and fix the position of arc plate 10 through auxiliary block 14, can effectively and timely remove harmful smoke in the course of operation, avoid causing certain harm to medical staff and patient.
[0027] When closing the abdomen, the organs are easy to accumulate together, and the blood is easy to be sucked close to the organs and tissues, so the sleeve pipe 4 can be sleeved outside the suction pipe 3, and the multiple round holes 7 and the blunt end of the sleeve pipe 4 can disperse the suction pressure, so that the organs and tissues are avoided to be sucked.
[0028] Of course, the above description is not limited to the above examples, and the technical features not described in the utility model can be realized by or using the prior art, which will not be repeated here; the above examples and drawings are only used for explaining the technical scheme of the utility model and are not limited to the utility model, and the ordinary skilled in the art should understand that the changes, modifications, additions or replacements made by the ordinary skilled in the art within the essential scope of the utility model do not deviate from the purpose of the utility model, and should also belong to the protection scope of the claims of the utility model.
