Description

TECHNICAL FIELD

[0002] At present, there are many patients with abdominal effusion in clinical practice. When the effusion is serious, it is often necessary to extract the effusion in the abdominal cavity. In the current extraction technology, a puncture bag is often used in combination with a suction machine and a suction head for suction. The puncture bag is matched with the suction pipeline to reduce the vibration of the suction pipeline during suction and the pain caused to the patient.

[0003] However, the existing effusion extraction device cannot control the size of the negative pressure, so that the suction pressure cannot be reduced in real time as the effusion decreases during the suction process, which may cause the suction device to work after the effusion is completely extracted, causing harm to the human body, or the suction may be stopped when the amount of effusion is less than a certain value, resulting in the retention of effusion in the patient's body and increasing the possibility of recurrence of abdominal effusion. In addition, the existing suction device cannot avoid blockage during the suction process. Blockage often occurs during the suction process, which increases the pain of the patient. After the effusion is extracted, some mucin particles may be splashed due to liquid shock, which may enter the suction machine under the action of the strong suction airflow of the suction machine and pollute the suction machine.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0024] Please refer to Figures 1-4The application provides the technical scheme: a negative pressure size adaptive effusion detection and extraction device, which comprises a suction machine 14, characterized in that: one side of the suction machine 14 is connected with a suction cylinder 1, the upper side of the suction cylinder 1 is provided with a suction pipeline 2, one side of the suction pipeline 2 is fixedly installed with a suction head 4, the inside of the suction pipeline 2 is provided with a negative pressure adjusting assembly, and the inside of the suction cylinder 1 is provided with a blockage processing assembly; the negative pressure adjusting assembly is arranged, so that the device can adjust the size of the negative pressure in real time, the suction rate is prevented from being too fast when the liquid level is low, the body is prevented from being harmed after the effusion is completely sucked, the suction rate can be improved when there is more effusion, the suction efficiency is increased, the pressure inside the abdominal cavity can be judged, the negative pressure can be adjusted in real time, the blockage processing assembly is arranged, so that the device can automatically increase the diameter of the suction pipeline after judging that the suction device is blocked, so as to solve the blockage, and the elastic filter screen inside the suction cylinder can be prevented from being blocked.

[0025] The negative pressure adjusting assembly comprises a hydraulic head 5, the hydraulic head 5 is fixedly installed at the bottom of the suction head 4, one side of the hydraulic head 5 is fixedly installed with a first pipeline 15, the other end of the first pipeline 15 is fixedly installed with a sealing plate 17, the outer side of the sealing plate 17 is fixedly installed with a circular ring plate 6, the inside of the circular ring plate 6 is sleeved with a sliding pin 13, the outer side of the circular ring plate 6 is provided with a resistance block 7, the sliding pin 13 is in sliding connection with the resistance block 7, one side of the sliding pin 13 is fixedly installed with an arc-shaped spring 12, one side of the arc-shaped spring 12 is fixedly installed with a sliding block 11, the right side of the resistance block 7 is electrically connected with a power supply, and one end of the sliding pin 13 is electrically connected with the suction machine 14. Figure 2As shown, the pressure received by the hydraulic head 5 in the effusion is proportional to the density of the effusion and the depth of the hydraulic head 5, and the density of the effusion is not very different, so it can be said that the pressure received by the hydraulic head 5 is proportional to the depth, and after the hydraulic head 5 sinks to the bottom of the effusion in the abdominal cavity of the human body, the depth of the effusion can be judged by the pressure received by the hydraulic head 5, and the difference between the abdominal cavities of different people is not very large, so the amount of effusion can be judged by the depth of the internal effusion in the abdominal cavity. After the hydraulic head 5 is subjected to pressure, it shrinks, causing the internal pressure to increase, and the internal pressure is transmitted to the lower side of the sealing plate 17 through the first pipeline 15, and the sealing plate 17 is driven to slide by the pressure of the belt to overcome the elastic force of the arc-shaped spring 12. The sliding needle 13 changes the position of the contact point of the sliding needle 13 and the resistance block 7, causing the value of the resistance in the circuit to change, thereby affecting the power of the suction machine 14, changing the size of the negative pressure in the suction cylinder 1. The above steps can be achieved. When the pressure received by the hydraulic head 5 is large, it is judged that the amount of effusion is large, the sliding distance of the sliding needle 13 to the right side is controlled to be large, and the resistance of the resistance block 7 connected to the circuit is small. At this time, the suction machine 14 obtains a large power, and the negative pressure in the suction cylinder 1 is large. When the pressure received by the hydraulic head 5 is small, it is judged that the amount of effusion is small, and the sliding distance of the sliding needle 13 to the right side is controlled to be small. At this time, the resistance of the resistance block 7 connected to the circuit is large. At this time, the suction machine 14 obtains a small power, and the negative pressure in the suction cylinder 1 is small. The amount of effusion is adjusted steplessly according to the size of the negative pressure, which ensures the extraction efficiency of the effusion and avoids the damage to the human body caused by the suction head 4 still sucking when the effusion is extracted.

[0026] The flexible ball 3 is provided outside the suction pipeline 2, one side of the flexible ball 3 is fixedly installed with the second pipeline 16, the inside of the circular ring plate 6 is connected with the sealing shell 8 through a bearing, the inside of the sealing shell 8 is fixedly installed with a rotating column, one end of the rotating column is fixedly installed with a rotating plate 9, the other end of the rotating column is slidingly connected with a fixed plate 10, the fixed plate 10 is fixedly installed on the circular ring plate 6, the side of the sealing shell 8 is fixedly installed with a force arm rod, the other end of the force arm rod is fixedly installed on the sliding block 11; as Figure 2As shown, the flexible ball 3 can determine the pressure inside the abdominal cavity, and adjust the initial position of the sliding block 11. Since hydrops is often accompanied by distension, which leads to a large pressure inside the abdominal cavity. When the negative pressure inside the suction cylinder 1 is constant, if the pressure inside the abdominal cavity is large, the suction speed will also increase due to the large pressure difference. The flexible ball 3 can determine the pressure inside the abdominal cavity. When the pressure inside the abdominal cavity is large, a pressure difference is generated with the inherent pressure inside the flexible ball 3, which further squeezes the flexible ball 3, increases the internal pressure of the flexible ball 3, and is transmitted to the closed shell 8 through the second pipeline 16. The pressure on the left side of the closed shell 8 increases, driving the rotating plate 9 to rotate and increase the volume between the rotating plate 9 and the fixed plate 10. The rotating plate 9 drives the closed shell 8 to rotate, and the rotating force brought by the pressure is amplified by the force arm rod, which further drives the sliding block 11 to move against the friction, changing the initial position of the sliding block 11. Through the above steps, when the distension inside the abdominal cavity leads to excessive pressure, the sliding block 11 slides clockwise, compresses the arc-shaped spring 12, and increases the difficulty of the right sliding of the slide pin 13. When the same amount of hydrops occurs, the negative pressure inside the suction cylinder 1 is smaller, avoiding the situation that the pressure difference is greater than the expected value due to the excessive pressure inside the abdominal cavity, which leads to excessive suction speed and threatens the human body. When the pressure inside the abdominal cavity is small, the sliding block 11 will slide counterclockwise, which further leads to the decrease of the difficulty of the right sliding of the slide pin 13. When the same amount of hydrops occurs, the negative pressure inside the suction cylinder 1 is larger, avoiding the situation that the pressure difference is less than the expected value due to the small pressure inside the abdominal cavity, which leads to slow suction speed and affects the suction efficiency.

[0027] The inside of the suction pipeline 2 is provided with a center cylinder 202, and the outside of the center cylinder 202 is uniformly provided with an anti-blocking cylinder 203. The outside of the anti-blocking cylinder 203 is provided with an annular pipeline 205, and the inside of the anti-blocking cylinder 203 is slidably connected with an anti-blocking rod 204 at the lower side of the annular pipeline 205. The anti-blocking rod 204 is elastically connected in the inside of the anti-blocking cylinder 203, and the other end of the anti-blocking rod 204 is fixedly installed on the suction pipeline 2. The two sides of the annular pipeline 205 are connected with air pressure balls 201, and the air pressure balls 201 are fixedly installed on the two sides of the suction pipeline 2. Figure 3As shown, when the blockage occurs inside the suction pipe 2, due to the continuous work of the suction machine 14, the negative pressure inside the suction cylinder 1 is continuously increased, and then the pressure difference between the air pressure ball 201 and the outside is generated, the air pressure ball 201 is expanded under the action of the pressure difference, and the internal pressure is reduced, at this time, the reduced pressure is transmitted to the inside of the annular pipe 205, and then the pressure on the upper side of the anti-blocking cylinder 203 is reduced, the anti-blocking rod 204 is moved out under the action of the elastic force, and then the diameter of the suction pipe 2 is increased, when there is still blockage, the negative pressure inside the suction cylinder 1 continues to increase, and then the internal pressure of the air pressure ball 201 continues to decrease, so that the diameter of the suction pipe 2 continues to increase, until the blockage is removed, the negative pressure assembly returns to normal, and the suction pipe 2 stops suction. Through the above steps, the diameter of the suction pipe 2 can be increased to solve the blockage, if the blockage is not solved, the negative pressure suction force of the suction pipe 2 will be increased and the diameter of the suction pipe 2 will be continuously increased, so as to increase the force to remove the blockage.

[0028] The inside of the suction cylinder 1 is fixedly installed with an elastic filter screen 21, the right side of the elastic filter screen 21 is fixedly installed with a limiting ball 19, one side of the limiting ball 19 is fixedly installed with an elastic ball 20, and the left and right sides of the elastic ball 20 are fixedly installed with elastic ropes 18, the elastic coefficients of the left and right elastic ropes 18 are the same, and the strength of the left elastic rope 18 is lower than that of the right elastic rope 18. Figure 4 As shown, the elastic filter screen 21 is used to filter small particles of mucin in the effusion, so as to avoid the pollution of the suction machine 14, when the elastic filter screen 21 is blocked, due to the continuous suction of the air on the right side by the suction machine 14, the pressure on the right side of the elastic filter screen 21 is continuously reduced, and then the elastic filter screen 21 is bent and deformed to the right under the pressure of the left side, and then the elastic rope 18 is continuously stretched, since the elastic coefficients of the two elastic ropes 18 are consistent, the elastic ball 20 will not move after being stretched, and the limiting ball 19 has viscosity, when the elastic filter screen 21 is not deformed, the limiting ball 19 is used to fix the position of the elastic ball 20, when it is bent to a certain degree, since the strength of the left elastic rope 18 is lower than that of the right elastic rope 18, the left elastic rope 18 is broken, and the elastic ball 20 is instantly subjected to a large elastic force, and then the elastic ball 20 hits the elastic filter screen 21 under the action of the elastic force, and shakes off the volatile substances of mucin adhered thereon, through the above steps, the elastic ball 20 can be used to hit the elastic filter screen 21 to remove the adhered substances thereon after the elastic filter screen 21 is blocked by the volatile substances in the effusion, so as to avoid the blockage and affect the operation of the rotor.

[0029] One side of the air pressure ball 201 is connected with the closed plate 17 through a pipeline; the change of the internal pressure of the air pressure ball 201 can be transmitted to the closed plate 17, and the change of the pressure in the closed plate 17 can also be transmitted to the air pressure ball 201. Through the above steps, when the negative pressure is gradually reduced by reducing the amount of liquid, a part of the gas in the air pressure ball 201 can also be extracted to offset the change of the internal pressure caused by the compression of the air pressure ball 201 due to the decrease of the external negative pressure. When the blockage occurs, the air pressure ball 201 continuously expands, causing the internal pressure of the closed plate 17 to be rapidly sucked in, the slide pin 13 slides to the left, and the power of the suction machine 14 is continuously reduced to reduce the rate of increase of the negative pressure, thereby avoiding the rapid increase of the negative pressure. At the moment when the blockage is unblocked, the pressure difference is too large to cause a dangerous situation.

[0030] The elastic filter screen 21 is provided with a plurality of groups of filter holes, and the inside of the filter hole is provided with activated carbon; after the elastic filter screen 21 is blocked, the elastic filter screen 21 is first bent to increase the length of the elastic filter screen 21, the internal filter hole is stretched, and the filter hole is enlarged, so that the originally blocked filter hole is unblocked, so that the gas can flow after the filter screen is blocked by bending, and when the bending degree is too large, the elastic ball 20 will quickly hit the elastic filter screen 21 to solve the blockage problem.

[0031] The flexible ball 3 is slidably connected with the suction pipeline 2; the flexible ball 3 can always float on the surface of the liquid by relying on its own buoyancy, so that the shape of the pipeline under the flexible ball 3 is limited by the flexible ball 3, avoiding the bending and accumulation of the pipeline in the liquid.

[0032] The air pressure ball 201 is made of elastic material; the air pressure ball 201 can quickly recover after deformation.

[0033] The suction head 4 is provided with a plurality of groups of suction holes at one end; the plurality of groups of suction holes are provided to avoid blockage during suction.
