3. connecting an anti-blocking connecting pipe 2 of the anti-blocking pipe with a suction head 4;
4. the suction tube 1 is connected with the anti-blocking tube through the anti-blocking connecting tube 2, and a sealing device 8 is arranged at the joint of the suction tube 1 and the anti-blocking connecting tube 2 and is firmly connected and sealed to achieve air and liquid leakage prevention;
5. the thumb or other fingers cover the negative pressure regulating hole 12 of the suction tube 1.
II, actual operation:
1. opening a negative pressure pipeline or a negative pressure device of a hospital, and covering the negative pressure adjusting hole 12 by fingers to generate negative pressure in the aspirator to form a negative pressure cavity;
2. meanwhile, opening an autologous blood reflux machine of a hospital, and inputting anticoagulant liquid into a suction tube 1 of a suction apparatus;
3. after a proper suction head 4 is selected to be connected with the connector 5, the suction head 4 is close to the part to be cleaned;
4. the suction force with different sizes is realized by completely or partially shielding the negative pressure adjusting hole 12 by fingers, and the debris, the waste liquid, the body fluid and other dirt of the tissue are sucked;
5. whether the interior of the anti-blocking piece 6 is blocked by the debris can be seen through the transparent suction tube 1;
6. after the debris is blocked, the suction pipe and the anti-blocking pipe are separated, the debris collected in the anti-blocking piece 6 is cleaned, and then all the parts are connected in reverse order, so that the suction work can be carried out again;
7. and (5) blocking again, and repeating the action of the step 5.
8. The suction apparatus is used as a disposable sterile product, and after suction work is finished, the suction apparatus is subjected to regular medical scrapping treatment and cannot be reused.
The utility model has the advantages and positive effects that: by adopting the technical scheme, the anti-blocking pressure-regulating aspirator is simple in structure, convenient to use, low in processing cost, provided with the anti-blocking tube, capable of filtering and intercepting debris and the like in the operation and preventing the suction tube from being blocked, and meanwhile provided with the negative pressure adjusting hole, capable of adjusting the negative pressure in the suction tube, further changing the suction force, changing the flow rate of the aspirator, expanding the use range of the aspirator, and suitable for various operations; the suction head and the anti-blocking pipe are detachably connected through the connector, so that the suction head can be replaced, the device is suitable for operation parts with different thicknesses and different depths, particularly for the existing minimally invasive surgery, the space is narrow, and the replacement of the small connector enables the surgery to be more convenient and flexible; the anti-blocking piece of the anti-blocking tube is detachably connected with the plug, so that the scraps can be easily and conveniently poured out, the surgical operations such as suction and the like are continued, and the blockage of the suction tube cannot be caused; the anti-blocking piece of the anti-blocking pipe is detachably connected with the first anti-blocking connecting pipe, and the first anti-blocking connecting pipe is detachably connected with the second anti-blocking connecting pipe, so that debris can be easily poured out of the anti-blocking piece, the suction pipe cannot be blocked, the anti-blocking piece and the plug are integrally formed, the anti-blocking piece is conveniently detached after the debris is not required to be filtered in surgical suction, and the suction apparatus can normally suck waste liquid, so that the suction apparatus is simple in structure and flexible to use; the anti-blocking piece adopts a reducing tubular structure, so that the debris is not easy to block, and the cleaning is convenient; the suction tube is connected with the negative pressure tube through the negative pressure tube interface, so that the suction tube is connected with a negative pressure device or a negative pressure pipeline of a hospital, the negative pressure tube is in a negative pressure state, and the flow rate of the suction apparatus is convenient to control; attract the pipe to pass through anticoagulation liquid interface and anticoagulation union coupling, increased anticoagulation function, avoid attracting the intraductal waste liquid of pipe to solidify, sunken negative pressure pipe interface makes the blood of most attraction all with the anticoagulation liquid contact of anticoagulation liquid interface outflow, plays anticoagulation effect, and anticoagulation pipe and the use of being connected hospital's autologous blood reinfusion machine, and autologous blood is returned again and is saved the blood transfusion, saves the operation expense.
The above description has been made in detail for the three embodiments of the present invention, but the above description is only for the preferred embodiment of the present invention, and should not be construed as limiting the scope of the present invention. All the equivalent changes and improvements made according to the application scope of the present invention should still fall within the patent coverage of the present invention.
