[0014]This invention utilizes a servo motor to drive a rotating ring block, which in turn pushes an intermittent wheel via a push rod. This intermittent rotation of the rotating disk and the pushing block allows the pushing block to compress the rubber air bladder after rotating to a certain angle. Subsequent rotations release the pressure on the air bladder, thus extracting air from the bottle through the compression and recovery of the rubber air bladder. This provides a convenient and simple solution for continuously extracting fluid from a patient's body, eliminating the need for repeated operations by medical staff or family members. It also solves the problem of the need for regular, scheduled pressing of the rubber air bladder, which can sometimes lead to insufficient negative pressure inside the bottle, affecting the effectiveness of the suction bottle in drawing out fluid.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of pleural effusion, specifically a cardiovascular surgical pleural effusion suction device. Background Technology
[0002] Pleural effusion aspiration may refer to a treatment method for pleural effusion, namely thoracentesis or chest tube drainage. Thoracentesis involves inserting a needle into the chest wall to aspirate the effusion in the pleural cavity. This method can quickly relieve the patient's breathing difficulties and chest pain, and can also analyze the effusion to help determine the cause.
[0003] In existing technologies, medical staff typically insert one end of a suction tube into the patient's body. By creating negative pressure within the suction bottle, they can absorb the fluid accumulated in the patient's body, thereby achieving a therapeutic effect. In some cases, a one-way venting rubber bladder is usually installed on one side of the suction bottle. By pressing the rubber bladder, the gas inside the bottle is expelled, maintaining a continuous negative pressure inside the bottle for continuous fluid absorption. However, pressing the rubber bladder requires regular operation by medical staff or family members. In some cases, medical staff or family members may forget to press the rubber bladder for various reasons, which may result in insufficient negative pressure inside the bottle, thus affecting the effectiveness of the suction bottle in absorbing the fluid.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0025] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.
[0026] This application discloses a cardiovascular surgical pleural effusion aspiration device. (Refer to...) Figure 1 and Figure 6 A cardiovascular surgical pleural effusion suction device includes a bottle body 1, a connecting hose 2 and a connecting tube 3 fixedly connected to the inner cavity of the bottle body 1, a rubber airbag 4 fixedly connected to one end of the connecting tube 3, an air outlet tube 5 fixedly connected to the inner cavity of the rubber airbag 4, a first one-way valve 6 fixedly connected to the surface of the connecting tube 3, a second one-way valve 7 fixedly connected to the surface of the air outlet tube 5, and a timing mechanism 8 provided on the surface of the rubber airbag 4.
[0027] The timing mechanism 8 includes a mounting frame 801. One side of the mounting frame 801 is fixedly connected to one side of the bottle body 1. A fixing plate 802 is fixedly connected to the inner cavity of the mounting frame 801. A servo motor 812 is fixedly connected to the inner cavity of the fixing plate 802. A rotating ring block 803 is fixedly connected to the output end of the servo motor 812. A push rod 804 is fixedly connected to one side of the rotating ring block 803. A fixing rod 805 is fixedly connected to the inner cavity of the mounting frame 801. An intermittent wheel 806 is rotatably connected to one end of the fixing rod 805. A connecting shaft 807 is fixedly connected to one side of the intermittent wheel 806. A rotating disk 808 is fixedly connected to one end of the connecting shaft 807. A pushing block 809 is fixedly connected to one side of the rotating disk 808. A spring 810 is fixedly connected to the inner cavity of the mounting frame 801. A sliding plate 811 is fixedly connected to one end of the spring 810.
[0028] Bottle 1 serves to install and fix the connecting hose 2 and the connecting tube 3. The connecting hose 2 can be connected to the external hose. Through cooperation with bottle 1, the negative pressure inside bottle 1 is used to squeeze and extract air from the patient's body. The connecting tube 3 can work with the rubber airbag 4 and the air outlet tube 5 to extract air from inside bottle 1, keeping the inside of bottle 1 under negative pressure. The first one-way valve 6 and the second one-way valve 7 can prevent backflow. When the rubber airbag 4 is pressed, the first one-way valve 6 allows the air inside the rubber airbag 4 to be discharged through the air outlet tube 5, preventing it from entering the inside of bottle 1 through the connecting tube 3. The second one-way valve 7 allows the rubber airbag 4 to block external air when it is not pressed, reducing the entry of external air.
[0029] Furthermore, the mounting bracket 801 can connect to the servo motor 812 via the fixing plate 802. When the servo motor 812 is operating, it can smoothly drive the rotating ring block 803 to rotate. The rotating ring block 803, in turn, drives the push rod 804 to rotate. The fixing rod 805 connects to the intermittent wheel 806, which in turn connects to the rotating disk 808 via the connecting shaft 807. When the push rod 804 rotates, it can smoothly insert into the intermittent wheel 806 and push it, causing the intermittent wheel 806 to rotate. It can rotate intermittently, and the intermittent wheel 806 can smoothly drive the push block 809 to rotate together through the rotating disk 808. When the push block 809 rotates, it can smoothly push the slide plate 811. When the slide plate 811 is pushed, it will squeeze the rubber air bag 4, so that the gas inside the rubber air bag 4 can be discharged. Afterwards, when the push block 809 stops squeezing the slide plate 811, the slide plate 811 can be reset by the elasticity of the spring 810, and the rubber air bag 4 can also be sucked in and restored by its own elasticity, thereby realizing the extraction of air from the inside of the bottle 1.
[0030] Reference Figure 4 The mounting bracket 801 has a groove 14 in its inner cavity. A slider 15 is fixedly connected to one side of the slide plate 811. The surface of the slider 15 is slidably connected to the inner cavity of the groove 14. The groove 14 can limit the sliding of the slide plate 811 through its connection with the slider 15, making it less likely to deviate during the sliding process and increasing its stability during sliding.
[0031] Reference Figure 4 The inner cavity of the slide groove 14 is fixedly connected to the limiting rod 16, and the inner cavity of the slider 15 is slidably connected to the surface of the limiting rod 16. The limiting rod 16 can limit the slider 15, so that the slider 15 has high stability while limiting the slide plate 811 through the slide groove 14.
[0032] Reference Figure 4 The inner cavity of the mounting bracket 801 is fixedly connected with a spring rubber block 17. One end of the spring rubber block 17 is fixedly connected to the bottom of the slide plate 811. The surface of the spring 810 is sleeved on the surface of the spring rubber block 17. The spring rubber block 17 can limit the extension and retraction of the spring 810, so that it is not easy to bend or deform during extension and retraction. At the same time, the spring rubber block 17 can also play an auxiliary role in restoring the slide plate 811 through its own elasticity.
[0033] Reference Figure 7 A reinforcing ring 10 is fixedly connected to one side of the rotating ring 803. The inner cavity of the reinforcing ring 10 is fixedly connected to the output end of the servo motor 812. The reinforcing ring 10 can reinforce the connection between the rotating ring 803 and the servo motor 812 through its connection with the rotating ring 803 and the output end of the servo motor 812. This ensures that the rotating ring 803 is stable enough when rotating and is not prone to shaking due to the connection with the output end of the servo motor 812, which could prevent the intermittent wheel 806 from being driven smoothly.
[0034] Reference Figure 6 and Figure 7 The inner cavity of the mounting bracket 801 is fixedly connected to a fixing ring block 11. The inner cavity of the fixing ring block 11 is fixedly connected to the surface of the fixing rod 805. The surface of the connecting hose 2 is fixedly connected to a rubber sleeve 9. The fixing ring block 11 can reinforce the fixing rod 805 through its connection with the mounting bracket 801, while the rubber sleeve 9 can seal the connection between the connecting hose 2 and the external hose, thereby increasing the sealing effect at the connection when the connecting hose 2 and the external hose are connected.
[0035] Reference Figure 2 and Figure 3 The bottom of the bottle body 1 is movably bonded with an anti-slip layer 18, a hook 12 is fixedly connected to one side of the bottle body 1, and a sealing rubber block 13 is fixedly connected to the top of the bottle body 1. The inner cavity of the sealing rubber block 13 is fitted onto the surface of the connecting hose 2. The anti-slip layer 18 can increase the friction between the bottom of the bottle body 1 and the object, and improve the stability of the bottle body 1 when it is placed. The hook 12 can make it convenient for medical staff to hang the bottle body 1 on the bedside or other locations, making it convenient to place the bottle body 1. The sealing rubber block 13 can increase the sealing of the connection between the connecting hose 2 and the bottle body 1, so that the connection between the connecting hose 2 and the bottle body 1 is not prone to air leakage.
[0036] Working Principle: In use, medical personnel connect the device to an external hose via the connecting hose 2, then insert the external hose into the patient's body. The negative pressure inside the bottle 1 allows for the extraction and suction of fluid from the patient's body. While the bottle 1 is extracting and suctioning fluid, the medical personnel can activate the servo motor 812. The servo motor 812 drives the rotating ring block 803 and the push rod 804 to rotate. The push rod 804, when rotating, smoothly inserts into the intermittent wheel 806, pushing it and causing it to rotate. The intermittent rotation of the intermittent wheel 806 then drives the connecting shaft 807 and the rotating disk 808 to rotate at a certain angle. After a certain period of rotation, the pushing block 809 connected to one side of the rotating disk 808 can push the sliding plate 811, so that the sliding plate 811 can squeeze the rubber airbag 4. When the rubber airbag 4 is squeezed, the gas inside it will be discharged to the outside through the air outlet pipe 5. Afterwards, after the intermittent wheel 806 continues to rotate to a certain angle, it will drive the pushing block 809 to release the squeezing of the rubber airbag 4. At this time, the sliding plate 811 can be reset by the elasticity of the spring 810, and the rubber airbag 4 can also be restored by its own elasticity. During the restoration, the air inside the bottle 1 is drawn out through the connecting pipe 3, so that the inside of the bottle 1 can continue to be kept in a negative pressure state, thereby continuously maintaining the inside of the bottle 1 in a negative pressure state, and continuously drawing and aspirating the accumulated fluid inside the patient's body.
[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
