Description

Technical Field

[0001] The present invention relates to the technical field of medical suction or pumping devices, and particularly to a fluid drainage device for cardiovascular medicine. Background Art

[0002] Cardiovascular medicine, abbreviated as cardiology, focuses on the diagnosis, treatment, and prevention of diseases of the heart and blood vessel systems, such as coronary heart disease, hypertension, cardiomyopathy, and valvular heart disease. During the treatment of cardiovascular diseases, it is inevitable to have situations such as pericardial effusion or pleural effusion. Therefore, it is necessary to use a drainage device to drain the fluid accumulated under the skin or in the cavity of the patient out of the body. At present, the drainage operation is mainly carried out by connecting a drainage tube to the fluid accumulation site of the patient and a suction device respectively, and the fluid in the patient's body is drained out through the drainage tube by the negative pressure of the suction device. However, since the fluid contains relatively viscous liquid, and in the prior art, it is impossible to flush and clean the inside of the drainage tube, the drainage tube often gets blocked during the drainage process. When the drainage tube is blocked, it is necessary to replace the drainage tube many times, which causes more pain to the patient to a certain extent and increases the medical cost. Therefore, a fluid drainage device for cardiovascular medicine is developed. Summary of the Invention

The two ends of the diversion tube are respectively rotatably connected to the drainage tube and the suction tube. A spiral blade is fixedly arranged on the inner peripheral wall of the diversion tube. A plurality of groups of drainage holes are evenly formed on the peripheral wall of the end of the drainage tube far from the diversion tube, and a plurality of drainage holes in each group are evenly arranged along the circumferential direction of the drainage tube. The suction tube is in an L shape, and the end far from the diversion tube is communicated with a suction machine. A water inlet pipe communicated with the inside of the suction tube is arranged on the outer side of the suction tube. One end of the water inlet pipe located inside the suction tube is communicated with one end of a telescopic corrugated water pipe, and the other end of the corrugated water pipe is communicated with a flushing ring pipe that can linearly move in the suction tube and the diversion tube. A plurality of nozzles are evenly arranged along the circumferential direction on the outer peripheral wall of the flushing ring pipe and on the side facing the drainage tube. A rotation driving mechanism for driving the diversion tube to rotate and a translation driving mechanism for driving the flushing ring pipe to linearly move are arranged on the suction tube.

[0006] Furthermore, the drainage tube and the suction tube are fixedly connected by a U-shaped connecting frame.

[0007] Further, connection sleeves are fixedly arranged at both ends of the diversion pipe, and limiting ring grooves are formed on the inner peripheral walls of the two connection sleeves; limiting ring protrusions adapted to the limiting ring grooves are fixedly arranged on the outer peripheral walls of the drainage pipe and the suction pipe near one end of the diversion pipe respectively.

[0008] Further, a rotary sealing ring is arranged between the outer peripheral wall of the limiting ring protrusion and the inner peripheral wall of the corresponding limiting ring groove.

[0009] Further, the rotary driving mechanism includes a first motor fixedly arranged outside the suction pipe, a first gear is arranged at the free end of the driving shaft of the first motor, and a transmission toothed ring adapted to the first gear is fixedly sleeved on the outer peripheral wall of the diversion pipe near one end of the suction pipe.

[0012] Further, a limiting slide bar parallel to the transmission screw rod is fixedly arranged inside the drainage pipe, one end of the limiting slide bar is fixedly connected with the side wall of the drainage pipe, the other end extends to one end of the diversion pipe near the drainage pipe, a limiting slide sleeve is slidably sleeved on the limiting slide bar, and the limiting slide sleeve is fixedly connected with the nut sleeve.

[0013] Further, a connector is fixedly arranged at the other end of the corrugated water pipe, and the connector is fixedly connected with the nut sleeve and the limiting slide sleeve through two connecting plates; the connector is communicated with the flushing ring pipe through two connecting pipes.

[0026] Example 1

[0027] As Figures 1 - 5 shown, a fluid drainage device for cardiovascular medicine department includes a drainage tube 1, a diversion tube 2 and a suction tube 3. The drainage tube 1 is used to communicate with the fluid accumulation part in the patient's body, and the suction tube 3 is used to communicate with an external suction device. The suction device involved in the present invention is a prior art, so it will not be described in detail in the specification.

[0028] Both ends of the diversion tube 2 are rotatably connected to the drainage tube 1 and the suction tube 3 respectively, and the three are sequentially in a mutually communicating relationship. The drainage tube 1 and the suction tube 3 are fixedly connected by a U-shaped connecting frame 29.

[0029] A plurality of groups of drainage holes 4 are evenly opened on the peripheral wall of the end of the drainage tube 1 away from the diversion tube 2, and the multiple drainage holes 4 in each group are evenly arranged along the circumferential direction of the drainage tube 1.

[0030] A spiral blade 5 is fixedly arranged on the inner peripheral wall of the diversion tube 2. Connecting sleeves 6 are respectively fixedly arranged at both ends of the diversion tube 2. Limiting ring grooves 7 are opened on the inner peripheral walls of the two connecting sleeves 6. Limiting ring protrusions 8 adapted to the limiting ring grooves 7 are respectively fixedly arranged on the outer peripheral walls of the ends of the drainage tube 1 and the suction tube 3 close to the diversion tube 2. Through the cooperation of the two groups of limiting ring grooves 7 and the limiting ring protrusions 8, the rotational connection between the diversion tube 2 and the drainage tube 1 and the suction tube 3 is realized. In addition, a rotary sealing ring 9 is installed between the outer peripheral wall of the limiting ring protrusion 8 and the inner peripheral wall of the corresponding limiting ring groove 7 to ensure the sealing performance of the connection part.

[0031] The shape of the suction tube 3 is L-shaped, and the end away from the diversion tube 2 is communicated with a suction machine. A water inlet pipe 10 communicating with its interior is installed on the outer side of the suction tube 3. The water inlet pipe 10 communicates with an external water source and a power pump (not shown in the figure) is installed in the middle of it. One end of the water inlet pipe 10 located inside the suction tube 3 is communicated with one end of a telescopic corrugated water pipe 11, and the other end of the corrugated water pipe 11 is communicated with a flushing ring pipe 12 that can linearly move in the suction tube 3 and the diversion tube 2. A plurality of nozzles 13 communicating with its interior are evenly installed along the circumferential direction on the outer peripheral wall of the flushing ring pipe 12 and on the side facing the drainage tube 1. A rotary driving mechanism for driving the diversion tube 2 to perform a rotational movement and a translational driving mechanism for driving the flushing ring pipe 12 to perform a linear movement are provided on the suction tube 3.

[0032] In this embodiment, the rotation driving mechanism includes a first motor 14 fixedly installed outside the suction tube 3. A first gear 15 is installed at the free end of the driving shaft of the first motor 14. A transmission gear ring 16 adapted to the first gear 15 is fixedly sleeved on the outer peripheral wall of one end of the diversion tube 2 close to the suction tube 3. When the first motor 14 drives the first gear 15 to rotate, the diversion tube 2 is rotated through the meshing transmission of the first gear 15 and the transmission gear ring 16.

[0033] In this embodiment, the translation driving mechanism includes a transmission screw rod 17 rotatably installed in the suction tube 3 and a second motor 18 fixedly installed outside the suction tube 3 for driving the transmission screw rod 17 to rotate. Specifically: A third gear 19 is installed on the driving shaft of the second motor 18. One end of the transmission screw rod 17 close to the second motor 18 extends outside the suction tube 3 and a fourth gear 20 adapted to the third gear 19 is installed at the end.

[0034] The transmission screw rod 17 extends to one end of the diversion tube 2 close to the drainage tube 1 and a limit head 21 is fixedly arranged at the end; A nut sleeve 22 is installed on the transmission screw rod 17 and is threadedly connected thereto. The outer diameter of the limit head 21 is larger than the inner diameter of the nut sleeve 22, and the nut sleeve 22 is fixedly connected to the flushing ring pipe 12. When the second motor 18 drives the transmission screw rod 17 to rotate, since the nut sleeve 22 maintains a threaded connection with the transmission screw rod 17, the nut sleeve drives the flushing ring pipe 12 to perform a linear motion.

[0035] A limit slide bar 23 parallel to the transmission screw rod 17 is fixedly arranged inside the drainage tube 3. One end of the limit slide bar 23 is fixedly connected to the side wall of the drainage tube 3, and the other end extends to one end of the diversion tube 2 close to the drainage tube 1. A limit slide sleeve 24 is slidably sleeved on the limit slide bar 23, and the limit slide sleeve 24 is fixedly connected to the nut sleeve 22. Through the sliding fit between the limit slide sleeve 24 and the limit slide bar 23, the movement stability of the flushing ring pipe 12 can be further ensured.

[0036] As a further improvement to this embodiment, the other end of the corrugated water pipe 11 is fixedly installed with a connector 25 communicated therewith. The connector 25 is fixedly connected to the nut sleeve 22 and the limit slide sleeve 24 respectively through two connecting plates 26; The connector 25 is communicated with the flushing ring pipe 12 through two connecting pipes 27. Through the connector 25, the flushing ring pipe 12 and the translation driving mechanism can be reasonably arranged inside the suction tube 3 and the material guiding tube 1.

[0037] When the present invention is in operation, the drainage tube is connected to the fluid accumulation site in the patient's body, and the suction tube is connected to an external suction device. Under the negative pressure of the suction device, the fluid in the patient's body enters the drainage tube through the drainage holes and is then drawn out through the diversion tube and the suction tube. During the hydraulic drainage process, the diversion tube is rotated by a first motor, and the spiral blades inside the diversion tube generate a driving force on the fluid flowing through it during rotation, thereby pushing the fluid forward and increasing the fluid flow rate to a certain extent, reducing the occurrence of blockage in the drainage channel. In addition, the present invention is also equipped with a scouring ring tube that can move linearly. Specifically, when the second motor drives the transmission screw to rotate, the nut sleeve drives the scouring ring tube to move linearly. The external cleaning water is supplied to the scouring ring tube through the water inlet pipe and the telescopic corrugated water pipe, and is sprayed outwards by the nozzles outside the scouring ring tube to achieve an automatic flushing effect, thereby preventing fluid from adhering to the inside of the drainage channel.

[0038] Embodiment 2

[0039] On the premise of not changing other structures of Embodiment 1, as Figure 6 shown, both ends of the nut sleeve 22 are respectively fixedly connected to one end of two telescopic corrugated protective sleeves 28 sleeved outside the transmission screw 17, and the other ends of the two corrugated protective sleeves 28 are respectively fixedly connected to the limiting head 21 and the inner wall of the suction tube 3. The two corrugated protective sleeves 28 are made of medical rubber. On the premise of not affecting the normal linear movement of the nut sleeve 22, the two corrugated protective sleeves 28 can isolate the fluid in the pipeline from the transmission screw, preventing the fluid from adhering to the transmission screw and affecting its normal use function.

[0040] The above-described embodiments are only descriptions of the preferred modes of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
