As a further embodiment of the present invention, a plurality of damping rings 30 are vertically fixedly connected to the inner side wall of the circular through groove 17; when the device works, the larger the suction force of the suction pump 101 is, the larger the flow speed of flushing liquid is, and after the flushing liquid enters the circular through groove 17, the flushing liquid acts with the damping ring 30 and has acting force for pushing the damping ring 30 upwards, so that the adjusting ball 13 is pushed upwards by pushing the damping ring 30, and the stability of the adjusting ball 13 is further maintained.
As a further embodiment of the invention, a fixing plate 32 is fixed on the inner wall of the first suction pipe 8, two communication holes 33 are symmetrically formed on the surface of the fixing plate 32, a movable rod 34 is penetrated in the middle of the fixing plate 32, one end of the movable rod 34 is fixed with a sealing disc 35, the other end of the movable rod 34 is fixed with a limiting plate 36, a second spring 37 is jointly fixed between the limiting plate 36 and the fixing plate 32, a blocking strip 38 is fixed at the end part of the inner wall of the fixing pipe 7, and the limiting plate 36 is contacted with the blocking strip 38; when the suction force is small, the first suction pipe 8 is pushed by the elastic force of the first spring 26 to be in a contracted state, at the moment, the limiting piece 36 is abutted against the blocking strip 38, so that the sealing disc 35 is not contacted with the fixing piece 32, flushing liquid can pass through the edge of the sealing disc 35 and pass through the communication hole 33 to enter the fixed pipe 7, when the suction force is large, the first suction pipe 8 can stretch out of the shell 3, so as to drive the fixing piece 32 to be far away from the fixed pipe 7, and under the elastic force pushing of the second spring 37, the limiting piece 36 drives the sealing disc 35 to move to the side close to the fixing piece 32 through the movable rod 34 and is tightly contacted with the fixing piece 32, so that the first suction pipe 8 can lose the suction function when the suction force is large, and thus the situation that the first suction pipe 8 is sucked by the first suction pipe 8 directly enters the fixed pipe 7 through the communication hole 33 is avoided.
A method of using a drainage device for clinical use in ICU critical medicine, the method comprising the steps of:
step one, sucking: the suction head 2 is inserted into the effusion, the suction pump 101 of the drainage device 1 is started, the suction pump 101 enables the inside of the suction head 2 to generate negative pressure through a conduit, and the effusion can be synchronously sucked through the first suction pipe 8 and the second suction pipe 12 under the action of the negative pressure;
step two, sucking more flushing liquid: when the flushing liquid is more, the suction speed is increased by increasing the suction force of the suction pump 101, and when the suction force is increased, the first suction pipe 8 is regulated to extend to the outer side of the shell 3 by the regulating mechanism, so that the distance between the second suction pipe 12 and the human body tissue is increased;
step three, sucking less flushing liquid: when the flushing liquid is less, the required suction force is smaller, and when the suction force is smaller, the first suction pipe 8 is driven by the adjusting mechanism to shrink towards the inside of the shell 3, so that the distance between the second suction pipe 12 and the human body tissue is reduced, and the flushing liquid is sucked.
The working principle of the invention is as follows:
when the suction head 2 is used, the suction head is inserted into the effusion, the sponge sleeve 11 on the suction ball 9 at the end part of the first suction pipe 8 is contacted with the body tissue of a patient, and the second suction pipe 12 which is directly opened is difficult to contact with the body tissue of the patient under the blocking effect of the first suction pipe 8, so that the condition that the second suction pipe 12 is directly sucked into the body tissue of the patient to cause damage to the body tissue of the patient is avoided; after the suction head 2 is placed, the suction pump 101 of the drainage device 1 is started, the suction pump 101 enables the interior of the suction head 2 to generate negative pressure through the guide pipe, under the action of the negative pressure, the accumulated liquid can be sucked synchronously through the first suction pipe 8 and the second suction pipe 12, because the second suction pipe 12 is directly communicated with the outside, human tissue fragments in the accumulated liquid can directly enter the interior of the second suction pipe 12 and enter the suction through cylinder along the second suction pipe 12, finally pass through the opening 4, enter the drainage device 1 along the guide pipe and are discharged from the liquid discharge pipe of the drainage device 1, so that the device can protect body tissues of a patient, synchronously suck the human tissues in the accumulated liquid, lighten the labor burden of medical nursing staff in operation, and further be beneficial to accelerating the operation speed; when the flushing liquid is more, in order to increase the suction speed, the medical staff increases the suction speed by increasing the suction force of the suction pump 101, when the suction force is increased, because the human tissues between the two first suction pipes 8 are softer, the distance between the second suction pipe 12 and the human tissues is reduced, under the action of suction force, the second suction pipe 12 possibly sucks the human tissues, and the damage to the human tissues occurs, when the suction force is increased, the device adjusts the first suction pipe 8 to extend to the outside of the shell 3 through the adjusting mechanism, so that the distance between the second suction pipe 12 and the human tissues is increased, and further, the human tissues are prevented from protruding to the side close to the second suction pipe 12 when the suction force of the suction pump 101 is larger, the distance between the second suction pipe 12 and the human tissues is reduced, the second suction pipe 12 sucks the human tissue to cause injury to the human tissue.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made therein without departing from the spirit and scope of the invention, which is defined by the appended claims.
