as shown in fig. 6, as another embodiment of the present invention, in comparison with the first embodiment, one end of the round ball 21, which is far away from the upper flow hood 17, is an outward convex oval, the middle part of one end of the round ball 21, which is near to the upper flow hood 17, is an inward concave, and a plurality of sets of circular protrusions are arranged outside the end, so that when working, the inward concave arrangement of one end of the round ball 21 and the plurality of sets of protrusions are matched, so that the round ball 21 can prop up the blocking pad 22, and at the same time, a part of space can be reserved at the bottom, so that the pericardial effusion can flow through the bottom of the round ball 21, and meanwhile, the arrangement of the convex mirror of the round ball 21 can be used for better observing the blood content in the pericardial effusion, further optimizing the observation effect of the display sheet 4 on the heavy blood content of the pericardial effusion, and improving the safety of the device during use.

The working principle is as follows: when the device works, the medical puncture needle 1 is inserted into the pericardial cavity of a patient, then the end part of the transmission pipe 2 is connected with the medical puncture needle 1, and the other end of the transmission pipe 2 is connected with a negative pressure pumping device such as a negative pressure bottle, so that effusion in the pericardial cavity can be smoothly pumped out, but severe pain is easily caused after a part of patients pump a large amount of effusion in the pericardial cavity, and a part of normal saline needs to be injected into the pericardial cavity in order to relieve the pain, but in the general process of injecting the normal saline, the previous medical puncture needle 1 needs to be pulled out, a new medical puncture needle 1 is inserted into the pericardial cavity, or a new transmission pipe 2 is replaced, and in any method, the device which is infused with the normal saline is required to be inserted into the sealing layer 10 in the extension pipe 3, and the middle part of the transmission pipe 2 is clamped, the negative pressure is stopped, and then the physiological saline can be input into the body of the patient through the medical puncture needle 1, so that the problem that the patient is easily subjected to secondary trauma in the process of puncture by replacing the transmission pipe 2 or inserting a new medical puncture needle 1 when the physiological saline is input into the patient is solved; when the device works, the pericardial effusion flows outwards along the transmission pipe 2 along with the extraction of the pericardial effusion, and the specific content of the pericardial effusion is difficult to judge, in the extraction process, when a large amount of blood is contained in the pericardial effusion, the extraction process is stopped immediately, but because the transmission pipe 2 is thin and the pericardial effusion is often reddish in blood, a doctor is not easy to capture the blood content in the pericardial effusion during observation, the excessive blood extraction can be realized after a large amount of blood is extracted easily, and through the arrangement of the flat display sheet 4, the pericardial effusion can be expanded and dispersed inside the display sheet 4 after entering the display sheet 4, so that the doctor can better observe the blood content of the pericardial effusion at the moment, and the safety of the operation process is improved; when the automatic blocking device works, when the physiological saline is injected to the inner side of the medical puncture needle 1 through the extension pipe 3, the setting of the first hose 5 is matched, the first hose 5 can be slowly expanded outwards through the physiological saline, meanwhile, the end part of the first hose 5 is pressed through the breaking rope 8, the first hose 5 can be expanded to the inner wall of the transmission pipe 2 and blocks the transmission pipe 2, so that the pericardial effusion which is drawn out from the transmission pipe 2 can not flow back into the pericardium, then the breaking rope 8 can be broken along with the continuous injection of the physiological saline, the end part of the first hose 5 can normally inject the physiological saline into a patient through the medical puncture needle 1, and the setting of the shearing opening is matched, so that the breaking rope 8 can be broken at the shearing opening to prevent the fragments of the breaking rope 8 from falling into the patient, thereby realizing the automatic blocking function and improving the mode of the transmission pipe 2 which is manually blocked, the blockage of the transmission pipe 2 can be realized only by injecting the normal saline into the extension pipe 3, so that the problem that the pericardial effusion returns to the pericardium along with the normal saline in the process of injecting the normal saline is effectively solved; when the device works, when the pericardial effusion starts to be extracted, the arrangement of the offset block 9 is matched, the pericardial effusion can be prevented from impacting the end part of the hose I5, if the pericardial effusion scours the end part of the hose I5 for a long time, the end part of the hose I5 is easy to be subjected to resistance, the breaking rope 8 is broken in advance, the hose I5 is opened, and the transmission pipe 2 is blocked, the semi-arc offset block 9 is matched, can block the pericardial effusion flowing through the end part of the hose 5, reduce the washing of the pericardial effusion to the end part of the hose 5, meanwhile, the drainage effect on the pericardial effusion can be achieved by matching the concave arc arrangement outside the offset block 9, the washing of the pericardial effusion on the end part of the hose 5 is further reduced, therefore, the problem that the hose I5 is easy to open in advance under the flushing of the pericardial effusion, so that the transmission pipe 2 is blocked, and the pericardial effusion cannot be normally extracted is solved; when the device works, when the first hose 5 expands outwards to block the transmission pipe 2, the friction between the first hose 5 and the inner wall of the transmission pipe 2 can be improved by matching the arrangement of the lug 6 and the blocking block 7, and meanwhile, because the lug 6 is made of an elastic material, after the lug 6 contacts the inner wall of the transmission pipe 2, the lug 6 can be extruded and contracted, and the friction force is further increased by increasing the contact area, so that the lug 6 is completely attached to the blocking block 7, the problem that when the first hose 5 expands outwards, the first hose 5 is easily deviated towards the negative pressure direction, the transmission pipe 2 is not completely blocked is solved, and finally, the problem that physiological saline is not injected into a patient along the transmission pipe 2 is easily solved; when the device works, the lug 6 can be hooked by matching with the barb-shaped arrangement of the blocking block 7, the hose I5 is prevented from moving towards the negative pressure direction under the action of negative pressure, so that the transmission pipe 2 is not completely blocked, and the problem that the physiological saline is easy to move towards two ends and is not completely injected into a patient body when the physiological saline is input is solved, and the semicircular cover shape at the other end of the blocking block 7 can increase the reaction force of the blocking block 7, prevent the blocking block 7 from turning over and changing the direction under the pushing of the lug 6, and finally prevent the transmission pipe 2 from being not completely closed; when the pericardial effusion flow display device works, when entering the display piece 4, the pericardial effusion enters the upper flow flowing cover 17 through the liquid inlet pipe 20, the transparent arrangement of the blocking pad 22 can directly observe the pericardial effusion inside the upper flow flowing cover 17, so that the pericardial effusion condition can be observed conveniently, the change of the blood content in the pericardial effusion can be observed, meanwhile, the semilunar arrangement of the blocking pad 22 is matched, the flowing line of the pericardial effusion is changed into the diffusion type flowing from the center to the two sides, the display effect of the pericardial effusion is effectively optimized, the pericardial effusion is prevented from flowing out from the liquid outlet pipe 12 along a straight line after directly flowing from the liquid inlet pipe 20 through the upper flow flowing cover 17, the pericardial effusion is prevented from being diffused in the display piece 4, the problem that the pericardial effusion is not completely displayed before, and the observation effect of the pericardial effusion in the display piece 4 is more obvious; when the device works, when the core bag effusion is required to be emergently suspended during the extraction, the display piece 4 is only required to be pressed towards the center, the attaching ball 14 can be pressed into the through hole 13, the hose II 15 is extruded to a closed state, the blocking function of the transmission pipe 2 can be completed at the moment, the emergency stopping function of the transmission pipe 2 is facilitated, medical workers can observe the blood content in the effusion of the core bag of the display piece 4 within sufficient time, and when the device is required to be opened again, the attaching ball 14 is only required to be pushed up to push out the through hole 13, the transmission pipe 2 can be communicated again, and the blocking of the transmission pipe 2 is facilitated; during operation, when negative pressure is taken out to the inboard of transmission pipe 2, lead to easily that blocking pad 22 caves in downwards, lead to that the pericardial effusion can not be fine to show in upper strata trickling cover 17, the setting of a plurality of groups ball 21 of cooperation this moment, not only can upwards jack-up certain height blocking pad 22, let blocking pad 22 can not drip the laminating of cover 17 with the upper strata, the transparent material of ball 21 of cooperation simultaneously, can be fine through the circumstances of the inside pericardial effusion of ball 21 direct observation upper strata trickling cover 17, and the setting of flexure strip 16, can be used for letting upper strata trickling cover 17 have certain toughness and rigidity, both guaranteed that display panel 4 can not become the fold under the pressure again, lead to observing the effect to reduce, also help driving the process of reciprocating of laminating ball 14 simultaneously, thereby further improved the function that display panel 4 observes the pericardial effusion.
