As shown in fig. 2, the fixing ring 2 includes an upper fixing ring 21 and a lower fixing ring 22 connected by a plurality of suspension rods 23, the upper fixing ring 21 is connected to the end portions of the side bars 11, and the inner side surface of the blower housing 3 is provided on the suspension rods 23.
In particular, the mounting frame 1 is provided in a structure form capable of being quickly fixed on a bed head or an operating table, for example, the mounting frame can be in plug connection, buckle connection or screw connection, etc. so that the device is convenient to move along with a patient.
The inside of the blast cover 3 is hollow or is provided with a plurality of pipelines communicated with the blast holes 5; the air blowing holes 5 are longitudinally arranged in rows, and each row of air blowing holes 5 is right opposite to the blood path pipe and the arrangement position of the air blowing holes is prevented from being blocked, so that pressurized air output by the outlet of the air blower 4 can be blown to the blood path pipe, and the air force blows the blood path pipe to vibrate, so that the coagulation phenomenon inside the blood path pipe is avoided, and the follow-up smooth blood flow is ensured.
As shown in fig. 3, three groups of vibration devices 6 are equidistantly arranged in each fixed ring 2, the vibration devices 6 comprise a long plate 61 and an arc-shaped plate 63 matched with a blood vessel, two ends of the long plate 61 are respectively arranged on the inner sides of the upper fixed ring 21 and the lower fixed ring 22, and the arc-shaped plate 63 is arranged on the long plate 61 through a plurality of repeated springs 62, so that the arc-shaped plate 63 is pressed on the outer surface of the blood vessel; when the compressed air conveyed by the blower 4 blows the blood path tube to vibrate, the blood path tube pushes the arc plate 63 and repeatedly vibrates under the action of the elastic force of the repeated spring 62, so that the vibration amplitude and the vibration frequency of the blood path tube are improved, and the blood is further promoted to form turbulence in the blood path tube.
As shown in fig. 4, the vibration damping device 9 is fixed on the mounting frame 1 through a connecting rod 14, and comprises an outer vibration damping tube 91, an inner vibration damping tube 93 and a conduit 94 for passing through a blood vessel, which are connected through a plurality of vibration damping springs 92, from outside to inside, wherein the conduit 94 is arranged under the fixed ring 2. When the blood tube arranged in the fixed ring 2 vibrates, the blood tube at the lower part of the fixed ring 2 can avoid irregular vibration under the limit of the vibration damper 9, so as to ensure the safety of the blood drawing process of the blood tube.
As shown in fig. 5, the dredging device 8 comprises an adjusting pipe 81 and an adjusting plug 82 slidably arranged in the adjusting pipe 81, the adjusting pipe 81 is arranged on the side surface of the pressure release pipe 7 in a communicated manner, an air filter screen 83 capable of allowing air to permeate is detachably arranged at the lower end of the adjusting plug 82, and an electric push rod 86 for driving the adjusting plug 82 to slide is arranged at the upper end of the adjusting plug 82.
Specifically, the sealing joints 71 disposed at two ends of the pressure release tube 7 can be quickly and hermetically connected with the blood path tube, so as to form a blood drawing loop. The air screen 83 acts as a "piston" within the regulator tube 81 that is permeable to air but impermeable to blood; when air in the blood path tube gathers, the air entering the pressure release tube 7 permeates into the adjusting tube 81 from the air filter 83, thereby reducing the high pressure of the blood path tube due to the air gathering.
In this embodiment, support blocks 84 are disposed on two sides of the adjusting tube 81, a fixing frame 85 is disposed on the support blocks 84, and the electric push rod 86 is disposed on the fixing frame 85 upside down, and its push rod end is connected with the top end of the adjusting plug 82.
Preferably, a pressure transmitter for detecting the pressure in the pressure release pipe 7 is arranged on the pressure release pipe, and the signal of the pressure transmitter 87 controls the start and stop of the electric push rod 86. The pressure transmitter 87 is arranged near the outlet end of the pressure relief pipe 7, and a high threshold value and a low threshold value are preset in the pressure transmitter; when air in the blood vessel gathers and the air filter 83 is not enough to exhaust excessive air, the pressure in the blood vessel continuously increases, and the pressure detected by the pressure transmitter 87 reaches a high threshold value, so that the electric push rod 86 is controlled to start and the regulating plug 82 is lifted upwards to reduce the pressure of the blood vessel; when the blood vessel is depressurized to make the pressure detected by the pressure transmitter 87 reach the low threshold value, the electric push rod 86 is controlled to stop and maintain the current running state.
When the blood drawing device is used, a blood drawing tube is built, the blood drawing tube is connected to the sealing joints 71 at the two ends of the pressure relief tube 7, the arc plates 63 are pushed outwards by hands, the blood drawing tube passes through the space surrounded by the three arc plates 63, and then the blood drawing tube passes out of the bottom end of the guide tube 94, and the blood drawing tube is connected with blood drawing equipment and a patient, so that a blood drawing loop is formed. Starting the blood drawing device and the air blower 4 (or starting the air blower 4 when the blood drawing is suspended due to the problem of blood purification), purifying the blood of a patient and then entering the body, when the blood flows through the fixed ring 2, the air blower 4 outputs the compressed air to blow the blood path tube to vibrate, and simultaneously, under the action of the vibration device 6, the blood generates local turbulence to avoid coagulation; the small bubbles formed by the air in the blood continuously escape from the air filter 83, and when a large pressure is generated inside the blood vessel due to the accumulation of air, the movement of the regulating plug 82 is controlled by the pressure transducer 87 to reduce the pressure inside the blood vessel.
