Description

Technical Field

[0001] The invention relates to the technical field of pleural effusion suction devices, and in particular to a pleural effusion suction device for cardiovascular surgery. Background Art

[0002] The chest drainage device is a device that places one end of the drainage tube into the chest cavity and connects the other end to a bottle at a lower position to discharge gas or collect fluid in the chest cavity, allowing the lung tissue to reopen and restore function. As a treatment method, closed chest drainage is widely used in the drainage of hemothorax, pneumothorax, empyema and after thoracotomy, and plays a vital role in the treatment of diseases.

[0003] During chest drainage, in order to prevent the effusion from blocking the drainage tube, medical staff need to regularly squeeze the chest drainage tube to keep the tube unobstructed and prevent blood clots or fibrous blocks from clogging it, which is an important nursing measure. However, the existing manual unblocking operation method is relatively cumbersome. The existing operation generally uses both hands to hold the tube and squeeze it, and the index finger, middle finger, ring finger, and little finger of both hands are used to squeeze the drainage tube. Squeeze from the proximal end of the drainage tube close to the chest cavity to the distal end close to the drainage bottle to push out the blood clots or fibrous blocks in the tube. However, due to the friction generated by the direct contact between the human hand and the drainage tube, and the influence of friction, the squeezing and unblocking operation is relatively cumbersome, which makes the work efficiency of medical staff low. Therefore, the present application provides a pleural effusion suction device for cardiovascular surgery to meet the needs. Summary of the invention

[0043] like Figure 1 and Figure 2As shown, an embodiment of the present invention provides a pleural effusion suction device for cardiovascular surgery, comprising an effusion extraction device body 1, a effusion extraction drainage tube body 2 is installed on the top of the effusion extraction device body 1, a connecting end 3 is fixedly connected to the bottom of the effusion extraction drainage tube body 2, a drainage port is arranged on the top of the effusion extraction device body 1, a water seal is arranged on the top of the effusion extraction device body 1, an outer shell body 4 matching the shape of the effusion extraction device body 1 is installed on the bottom of the effusion extraction device body 1, a thickened side strip 5 is fixedly connected to the top of the outer shell body 4; a drainage anti-slip mechanism, the drainage anti-slip mechanism is used to prevent The connection between the main body 1 of the effusion extraction device and the main body 2 of the effusion extraction drainage tube is prevented from loosening or falling off during drainage, and the drainage anti-falling mechanism is connected to the thickened edge strip 5; the drainage auxiliary mechanism is used to assist in the fixation of the main body 1 of the effusion extraction device, and the drainage auxiliary mechanism is connected to the thickened edge strip 5. When the device is used for pleural effusion drainage, the main body 1 of the effusion extraction device and the main body 2 of the effusion extraction drainage tube are connected, so that the connecting end 3 is installed on the drainage port at the top of the main body 1 of the effusion extraction device, and the main body 1 of the effusion extraction device and the main body 2 of the effusion extraction drainage tube are sealed and connected, and the effusion extraction device The specific structure and working principle of the main body 1 and the fluid extraction drainage tube body 2 are existing mature technologies, so they will not be described in detail here. The fluid extraction device body 1 is placed in the outer shell body 4, and the outer shell body 4 protects the side and bottom of the fluid extraction device body 1, effectively preventing the fluid extraction device body 1 from being accidentally touched and squeezed during use, resulting in changes in the negative pressure inside, thereby causing the problem of liquid reflux. The drainage auxiliary mechanism can also assist in the installation of the fluid extraction device body 1, so that the fluid extraction device body 1 can be used when the patient is lying on the bed or going to the toilet. It can be quickly fixed near the patient, so that the device is easy to use in different usage conditions, and the drainage anti-falling mechanism can also be used to strengthen the connection between the fluid extraction device body 1 and the fluid extraction drainage tube body 2 to prevent the connection between the fluid extraction device body 1 and the fluid extraction drainage tube body 2 from being pulled during use and causing looseness, resulting in a poor sealing effect. The working principles of the above-mentioned drainage auxiliary mechanism and drainage anti-falling mechanism are described in detail below and will not be elaborated on here. In addition, the device has a simple structure and is relatively convenient and quick to use. The device has good practicality and is easy to promote and use.

[0044] Among them, the shell body 4 is provided with first lightweight grooves 6 at equal intervals, which can reduce the mass of the shell body 4. The shell body 4 and the thickened side strips 5 are integrally constructed. The shell body 4 is made of plastic material. Through the construction of plastic material, the production cost of the shell body 4 is lower, and the weight is lower, and the stability of the integral structure is better. The setting of the thickened side strips 5 further enhances the strength of the top edge of the shell body 4, so that the shell body 4 is not prone to strong bending deformation when accidentally touched, and the structure is simple, and the coordinated use of the structures further makes the use effect of the device better.

[0045] like Figures 6 to 11 As shown, the drainage anti-slip mechanism includes a connecting strip 12 installed on the thickened edge strip 5, the top of the connecting strip 12 is fixedly connected to a limiting plate frame 13, the top of the limiting plate frame 13 is fixedly connected to a limiting auxiliary plate 14, and the top of the limiting auxiliary plate 14 is annularly equidistantly installed with rolling balls 15. The connecting strip 12 is an arc-shaped structure convex to the top in a natural state, so that the limiting plate frame 13 and the limiting auxiliary plate 14 fixedly connected thereto always have a tendency to approach the outer shell body 4. By utilizing the connecting strip 12 and the limiting plate frame 13 and the limiting auxiliary plate 14 on its top, the effusion extraction and drainage tube body 2 can be always tightly connected to the drainage port on the top of the effusion extraction device body 1 during use, so as to prevent the effusion extraction and drainage tube body 2 from being pulled when the patient moves his body, causing the connection between the effusion extraction device body 1 and the connecting end 3 to become loose, and utilizing the limiting auxiliary plate 14 The rolling ball 15 arranged on it can also facilitate the squeezing and unblocking operation of the fluid extraction and drainage tube body 2 when the limiting plate frame 13 and the limiting auxiliary plate 14 are separated from the connecting strip 12. When the limiting plate frame 13 and the limiting auxiliary plate 14 are used to unblock the fluid extraction and drainage tube body 2, the rolling ball 15 is directly in contact with the outer wall of the fluid extraction and drainage tube body 2, which can not only effectively reduce the friction between the fluid extraction and drainage tube body 2 and the unblocking structure, but also use a plurality of rolling balls 15 to squeeze the fluid extraction and drainage tube body 2, which makes it easier to break the blood clots in the fluid extraction and drainage tube body 2, thereby making it easier to unblock the blood clots in the fluid extraction and drainage tube body 2. The coordinated use of the structures further facilitates the operation of medical staff and improves the work efficiency of medical staff to a certain extent. In addition, the simple structure and the coordinated use of the structures further make the use effect of the device better.

[0046] Among them, a third weakened portion 23 is provided on one side of the connecting strip 12 close to the limiting plate frame 13, and the deformation tendency of the slot 22 is enhanced by the setting of the third weakened portion 23, so that the connection between the connecting end 3 and the main body 1 of the effusion extraction device is more tightly connected, and a third lightweight groove 24 is provided on the limiting plate frame 13, which reduces the mass of the third weakened portion 23 and enhances the deformation capacity of the third weakened portion 23. A ball groove 26 adapted to the shape of the ball 15 is provided on the limiting auxiliary plate 14, so that the ball 15 can roll therein, and a third guide portion 25 is provided on one side of the limiting auxiliary plate 14, which is convenient for use. The guidance of the third guide part 25 can quickly insert the fluid extraction and drainage tube body 2 into the third lightweight groove 24. The limiting plate frame 13 and the limiting auxiliary plate 14 are integrated. The limiting plate frame 13 and the limiting auxiliary plate 14 are made of plastic material. The integrated structure has better stability, the plastic material is lighter, and it has good deformation ability. Some of the limiting auxiliary plates 14 close to the third guide part 25 are provided with a second buffer cavity 31. By using the second buffer cavity 31 and the third guide part 25 in coordination, the fluid extraction and drainage tube body 2 can be further more quickly inserted into the third lightweight groove 24.

[0047] The limiting auxiliary piece 14 is provided with segmented grooves 27 at equal intervals in an annular manner. The segmented grooves 27 are used to make it easier for the third lightweight groove 24 to deform from the segmented grooves 27 when subjected to pressure. A fourth weakened groove 28 is provided at the connection between the limiting piece frame 13 and the limiting auxiliary piece 14. The fourth weakened groove 28 is used to make it easier for the connection between the third weakened portion 23 and the third lightweight groove 24 to deform under the action of external force, so that the rolling ball 15 on the third lightweight groove 24 can be aligned with the effusion extraction drainage tube itself. The outer wall of the body 2 is in direct contact, and a slide groove 29 is provided on the side of the limiting plate frame 13 close to the connecting strip 12. A slider 30 that is adapted to the shape of the slide groove 29 is fixedly connected to the side of the connecting strip 12 close to the limiting plate frame 13. By utilizing the coordinated use of the slide groove 29 and the slider 30, the connecting strip 12 and the limiting plate frame 13 can be quickly connected or separated, and the structure is simple. The coordinated use of the structures further makes the use effect of the drainage anti-slip mechanism better, and the structure is relatively simple, which is convenient for medical staff to use and operate.

[0048] like Figures 1 to 7As shown, the drainage auxiliary mechanism includes a limiting frame 7 installed on the thickened edge strip 5, and one side end of the limiting frame 7 is fixedly connected to a first end piece 9, and the other side end of the limiting frame 7 is fixedly connected to a second end piece 10. The limiting frame 7, the first end piece 9 and the second end piece 10 are an integrated structure, and the integrated structure has better stability. The shape of the second end piece 10 is adapted to the shape of the vertical rod on the nursing bed in the hospital. By utilizing the guidance of the first end piece 9 and the second end piece 10, the patient can quickly clamp the limiting frame 7 on the patient's calf when using the device to the toilet, without the need for the patient or his family to carry the device by hand, and the setting of the second end piece 10 can also quickly fix the limiting frame 7 to the edge of the nursing bed, thereby facilitating the placement and use of the main body 1 of the effusion extraction device when the patient is resting on the nursing bed. The structure is simple, and the coordinated use of the structures further improves the use effect of the device.

[0049] like Figures 1 to 7 and Fig. 9 As shown, a first guide portion 11 is provided on the side of the second end piece 10 away from the first end piece 9. The first guide portion 11 and the structural guidance at the edge of the limiting frame 7 can make the second end piece 10 more quickly installed on the side rod of the nursing bed. The cross-section of the limiting frame 7 is C-shaped, which is convenient for fixing the limiting frame 7 on the patient's leg, and also convenient for the limiting frame 7 to assist in strengthening the structure of the outer shell body 4, so that the outer shell body 4 cooperates with the use of the limiting frame 7 to better protect the main body 1 of the effusion extraction device. The outer wall edges of the limiting frame 7, the first end piece 9 and the second end piece 10 are arc-shaped, and the arc shape has no obvious edges and corners, which prevents medical staff from accidentally scratching when using the device. Second lightweight grooves 8 are equidistantly provided on the limiting frame 7, which enhances the deformation ability of the limiting frame 7 and reduces the weight of the limiting frame 7. The limiting frame 7, the first end piece 9 and the second end piece 10 are made of plastic material, the cost of plastic material is lower, and the deformation ability of the structure itself is further enhanced.

[0050] The top of the limiting frame 7 is provided with three slots 22, and the bottom of one side of the thickened edge strip 5 is fixedly connected with an insertion rod 16. By using the insertion rod 16 and the slot 22 in combination, the limiting frame 7 can be quickly installed directly below or on the side of the thickened edge strip 5, so that the device can be quickly switched for use when the patient is lying or sitting. The bottom of the insertion rod 16 is fixedly connected with an end block 17, and the bottom of the insertion rod 16 is limited by the setting of the end block 17 and the slot 22 whose shape matches the end block 17, so that the insertion rod 16 and the end block 17 are more stably installed at the bottom of the thickened edge strip 5, so that the connection between the shell body 4 and the limiting frame 7 is tighter, and a first buffer cavity 18 is provided in the end block 17, and the bottom of the end block 17 A second guide portion 19 is provided, and the first buffer cavity 18 is squeezed and deformed, and guided by the second guide portion 19, so that the insertion rod 16 and the end block 17 can be installed into the slot 22 more quickly. A first weakened portion 20 is provided in the middle of the limiting frame 7, and second weakened portions 21 are provided on both sides of the limiting frame 7. Through the opening of the first weakened portion 20 and the second weakened portion 21, the limiting frame 7 can first be deformed from the first weakened portion 20 and the second weakened portion 21 under the action of external force, so that the limiting frame 7 can be quickly fixed on the patient's leg for use, and the structure is simple, and the coordinated use of the structures further makes the use effect of the device better, and the structure is simple, and it is convenient and quick to use.

[0051] The workflow of the technical solution provided by the present invention is as follows:

[0052] When in use, the main body 1 of the fluid extraction device and the main body 2 of the fluid extraction drainage tube are connected, so that the connecting end 3 is installed on the drainage port on the top of the main body 1 of the fluid extraction device, and the main body 1 of the fluid extraction device and the main body 2 of the fluid extraction drainage tube are sealed and connected. The specific structure and working principle of the main body 1 of the fluid extraction device and the main body 2 of the fluid extraction drainage tube are existing mature technologies, so they are not described in detail here. Then the main body 1 of the fluid extraction device is placed in the outer shell body 4, and the outer shell body 4 protects the side and bottom of the main body 1 of the fluid extraction device, effectively preventing the main body 1 of the fluid extraction device from being accidentally touched and squeezed during use, resulting in negative pressure inside it. Changes occur, which leads to the problem of liquid reflux. Then, the limiting auxiliary piece 14 is quickly clamped on the bottom of the fluid extraction and drainage tube body 2 by utilizing the guidance of the third guide part 25 and the buffering effect of the second buffer cavity 31, and the limiting piece frame 13 is sleeved on the connecting end 3. By utilizing the deformation tendency of the connecting strip 12 and the coordinated use of the limiting piece frame 13 and the limiting auxiliary piece 14 on the top thereof, the fluid extraction and drainage tube body 2 can be always tightly connected with the drainage port on the top of the fluid extraction device body 1 during use, so as to prevent the fluid extraction and drainage tube body 2 from being pulled when the patient moves his body, causing the connection between the fluid extraction device body 1 and the connecting end 3 to loosen.

[0053] When blood clots are generated in the fluid extraction and drainage tube body 2 and block the fluid extraction and drainage tube body 2, the slider 30 is made to slide in the slide groove 29 to separate the limiting plate frame 13 and the connecting strip 12, and then the limiting plate frame 13 and the limiting auxiliary plate 14 are squeezed by hand to deform the limiting plate frame 13 and the limiting auxiliary plate 14 so that the rolling ball 15 is in close contact with the outer wall of the fluid extraction and drainage tube body 2, and then the limiting plate frame 13 and the limiting auxiliary plate 14 are squeezed with the index finger, middle finger, ring finger and little finger of both hands to transmit the squeezing force to the drainage tube through the limiting plate frame 13 and the limiting auxiliary plate 14. Squeeze from the proximal end of the drainage tube close to the chest cavity to the distal end close to the drainage bottle, so that the intermittently distributed rolling balls 15 squeeze the fluid extraction and drainage tube body 2 to push out the blood clots or fiber blocks in the tube, and then quickly squeeze and dredge the fluid extraction and drainage tube body 2. In addition, when the fluid extraction and drainage tube body 2 is dredged by using the limiting plate frame 13 and the limiting auxiliary plate 14, the rolling balls 15 are directly in contact with the outer wall of the fluid extraction and drainage tube body 2, which can not only effectively reduce the friction between the fluid extraction and drainage tube body 2 and the dredging structure, but also use a plurality of rolling balls 15 to squeeze the fluid extraction and drainage tube body 2, which makes it easier to break the blood clots in the fluid extraction and drainage tube body 2, thereby making it easier to dredge the blood clots in the fluid extraction and drainage tube body 2, thereby improving the work efficiency of medical staff to a certain extent.

[0054] And because the segmented grooves 27 are equidistantly arranged in an annular manner on the limiting auxiliary plate 14, the segmented grooves 27 can make the third lightweight groove 24 more easily deformed from the segmented grooves 27 when subjected to pressure, and the fourth weakened groove 28 is arranged at the connection between the limiting plate frame 13 and the limiting auxiliary plate 14. The fourth weakened groove 28 makes it easier for the connection between the third weakened part 23 and the third lightweight groove 24 to deform under the action of external force, so that the rolling ball 15 on the third lightweight groove 24 can directly contact the outer wall of the effusion extraction drainage tube body 2. When the patient uses the device in a lying position, the limiting frame 7 can be quickly fixed to the edge of the nursing bed by utilizing the setting of the second end piece 10, so as to facilitate the placement and positioning of the effusion extraction device body 1 when the patient is resting on the nursing bed. When the patient needs to go to the toilet, the first end piece 9 and the second end piece 10 are used to guide the limiting frame 7 to be set on the patient's calf, so that the patient or his family members do not need to carry the device when using the device to the toilet. The use of the insertion rod 16 and the slot 22 can make the limiting frame 7 quickly installed just below or on the side of the thickened edge strip 5, so that the device can be quickly switched for use when the patient is lying or sitting, and through the opening of the first weakened portion 20 and the second weakened portion 21, the limiting frame 7 can be deformed first from the first weakened portion 20 and the second weakened portion 21 under the action of external force, so that the limiting frame 7 can be deformed faster to adapt to the shape of the patient's calf. The structure of the device is simple and it is convenient to use.
