Description

Technical Field

[0001] The invention belongs to medical equipment technology, and specifically relates to an anti-blocking drainage device for treating thoracic surgical diseases. Background Art

[0002] Thoracic surgery is a medical specialty that focuses on the study of organs within the chest cavity, mainly referring to the diagnosis and treatment of esophageal, lung, and mediastinal diseases. The field of breast surgery is also included in this specialty, among which lung surgery and esophageal surgery are the main ones. Thoracic surgery mainly refers to the diagnosis and treatment of esophageal, lung, and mediastinal diseases. The drainage device is a commonly used treatment method in clinical thoracic surgery. One end of the drainage tube is placed in the chest cavity to discharge gas or collect fluid in the chest cavity.

[0003] When using a drainage device, the drainage fluid often contains various debris, such as blood, lymph, tissue fragments, cells, pus, etc. These debris are waste and secretions generated during the operation, which can easily cause the drainage tube to be blocked, making it very inconvenient to use, causing a lot of trouble for doctors, and causing additional pain to patients. In the current technology, in order to prevent the drainage tube from being blocked, a debris crushing mechanism is often set in the drainage tube, such as a thoracic surgery anti-blocking drainage device with application number CN202122912169.2, which enables the squeezing rod to reciprocate in the drainage tube, so that the squeezing rod and the fixed rod can crush waste such as blood clots in the drainage tube, prevent the drainage tube from being blocked, improve the discharge efficiency of pleural effusion, and reduce the patient's pain.

[0004] The drainage device in the above-mentioned comparative case has a relatively simple structure and still has many problems. For example, in actual use, the debris in the drainage tube can only be crushed, and these debris may contain some pus, mucus and flocs with high viscosity. These debris have high viscosity and are easy to adhere to the inner wall of the drainage tube. If there are too many adhered debris, it will not only easily cause the drainage tube to be blocked, but also difficult to clean later, which will seriously contaminate the drainage tube. In addition, the drainage tube is installed relatively fixedly, which is not convenient for replacement, and it is difficult to ensure cleanliness after long-term use. Summary of the invention

In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0037] Example 1

[0038] Please see attached Figure 1-5 FIG. 1 is a first embodiment of the present invention, which provides an anti-blockage drainage device for treating thoracic surgical diseases, comprising:

[0039] A frame 1, a screening box 2 and a housing 3, one side of the housing 3 is detachably connected with a drainage pipe 4;

[0040] The anti-blocking mechanism 6 is arranged inside the drainage pipe 4;

[0041] A driving part 5, which is arranged on one side of the screening box 2, and the driving part 5 drives the anti-blocking mechanism 6 to reciprocate along the inside of the drainage pipe 4 through the transmission mechanism 7, wherein a protective shell is further provided on the outside of the transmission mechanism 7 (specifically, a detachable cover is provided on the protective shell, which is convenient for opening the protective shell to inspect and maintain the transmission mechanism 7, and a slot is also provided on the protective shell, and the anti-blocking mechanism 6 penetrates the slot and is connected to the transmission mechanism 7);

[0042] The anti-blocking mechanism 6 includes a round rod 61 , a crushing part 62 and a cleaning part 63 . The round rod 61 is inserted into the shell 3 and horizontally placed inside the drainage pipe 4 . The crushing part 62 and the cleaning part 63 are both arranged on the round rod 61 .

[0043] In this embodiment, when the device is used to drain the effusion in the thoracic cavity, the device can be connected to a negative pressure device, and the negative pressure can drive the cleaning part 63 to rotate by utilizing the negative pressure drainage, so as to perform online maintenance on the inner wall of the drainage pipe 4. At the same time, the driving part 5 can drive the anti-blocking mechanism 6 to move inside the drainage pipe 4 through the transmission mechanism 7, and the large impurities in the effusion can be crushed by the crushing part 62 on the round rod 61, and the drainage pipe 4 can be cleaned and maintained by the cleaning part 63 to prevent the impurities in the effusion from being blocked in the drainage pipe 4.

[0044] Secondly, please also refer to Figure 1 and5 A connector 8 is also provided at one end of the drainage pipe 4, and the connector 8 is used to connect the drainage hose. The frame 1 consists of a box body and a slag discharge pipe, wherein a collecting box 10 is installed on the top surface of the box body, one side of the collecting box 10 is connected to the screening box 2, and the other side is connected to the box body, and a filter screen is provided at the connection with the box body, wherein a negative pressure pipe 11 is connected to the shell body 3, and a driving rod 12 is rotatably connected to both ends of the screening box 2 through a sealed bearing, and one end of the driving rod 12 is connected to the output shaft of the driving part 5, and an auger conveying blade 13 is sleeved on the outer wall of the driving rod 12, wherein an arc-shaped filter plate is provided inside the screening box 2. In addition, whether it is an arc-shaped filter plate or a filter screen, it can be taken out from the inside of the equipment, which is convenient for subsequent replacement or cleaning. A pull-out design is adopted here. Of course, other structures that can be taken out are also possible, and they are not described in detail here.

[0045] In this embodiment, a drainage hose is connected to an external connector 8, the drainage hose is inserted into the patient's chest cavity, and the negative pressure pipe 11 is connected to the negative pressure device, and the negative pressure device is used to draw air to generate negative pressure inside it. Under the action of negative pressure, the accumulated fluid in the patient's chest cavity will be drawn in along the external drainage hose, the connector 8 and the drainage pipe 4, and then the accumulated fluid will fall from the shell 3 into the screening box 2, and the accumulated fluid will be filtered by the filter plate inside the screening box 2. The accumulated fluid will flow into the frame 1, and impurities in the accumulated fluid will be blocked. The driving part 5 is started to drive the driving rod 12 to rotate and rotate the auger conveying blade 13 (the driving part 5 can be an electric motor), and the auger conveying blade 13 is used to drive the filtered impurities to move to the left, and then they are transported by the auger conveying blade 13 and fall into the collection box 10; and a filter screen is provided at the connection between the collection box 10 and the box body, and the residual liquid in the collection box 10 is filtered again through the filter screen.

[0046] It should be noted that the dual design of the arc filter plate and the filter screen is intended to separate the liquid and tissue in the effusion, so that the hospital can analyze the components of the effusion. Although the present application involves a crushing unit 62 for crushing, in fact, the crushing unit 62 does not completely crush the tissue, but cuts it to a certain extent, as long as it does not affect the subsequent negative pressure. Specifically, the cutting effect depends on the rotation speed of the driving unit 5. When the rotation speed is high, the crushing is more thorough, and when the rotation speed is low, the cutting purpose is achieved. Finally, when calculating the solid-liquid ratio, the arc filter plate and the filter screen can be pulled out and weighed to calculate their weight, and the liquid can be removed and weighed. Considering the adhesion situation, a weighing scale (equipped with a container) can be directly built into the frame 1 for accurate weighing.

[0047] Specifically, the driving unit 5 adopts products currently available on the market. When selecting a model, it should be selected as much as possible to meet the requirements of this application under the premise of being suitable for the specifications and usage scenarios. The specific model specifications are not limited here.

[0048] Secondly, please refer to Figure 1 The connector 8 is composed of a hose and a hard tube, and elastic steel rings are arranged in an array on the hose. The connector 8 is composed of a hose and a hard tube. While being convenient for bending and stretching, it is also convenient for connecting with the external drainage hose. The elastic steel ring can prevent the hose from being sucked flat by excessive negative pressure.

[0049] In addition, the connector 8 is designed to be disposable. After use, the connector 8 can be directly removed, and then the cleaning and disinfecting liquid is connected through a water pump, and the water pump outlet pipe is connected to the drainage pipe 4 through a connecting pipe. At the same time, the drive part 5 is started, and the water pressure is used in conjunction with the drive part 5 to clean the inside of the equipment. The whole cleaning process is relatively simple. In view of the fact that the crushing part 62 and the cleaning part 63 are difficult to clean, the drainage pipe 4 is installed on the shell 3 in a detachable manner. The specific implementation method can be a flange connection, or other connections that can ensure sealing. After the drainage pipe 4 is removed, the crushing part 62 and the cleaning part 63 will be exposed, which is convenient for cleaning and maintenance.

[0050] Next, please refer to Figure 6 The crushing part 62 includes a rotating rod 621 and a support frame 624. The rotating rod 621 is rotatably connected to the drainage pipe 4. A gear 622 is sleeved on the middle end of the rotating rod 621. The outer walls of both ends of the rotating rod 621 are sleeved with crushing blades 623. The support frame 624 is connected to the round rod 61, and a tooth groove matched with the gear 622 is opened on one side of the support frame 624.

[0051] In this embodiment, the round rod 61 drives the support frame 624 to move left and right when it moves left and right. The tooth grooves on the support frame 624 mesh with the gear 1 622 for transmission, so that the gear 1 622 drives the rotating rod 621 to rotate. The rotation of the rotating rod 621 drives the crushing blades 623 at both ends to rotate to crush the impurities in the accumulated liquid, thereby reducing the volume of the impurities in the accumulated liquid, increasing the flow rate of the accumulated liquid, and avoiding accumulation or blockage caused by excessive volume of impurities.

[0052] Please refer again Figure 7 The cleaning part 63 includes a collar 631, which is rotatably connected to the round rod 61 through a bearing, a circular ring 632 is fixedly sleeved on the outer wall of one end of the collar 631, a scraper 633 is fixedly connected to the circular ring 632, and an impeller 634 is fixedly sleeved on the outer wall of the other end of the collar 631, wherein the scraper 633 has an elastic sheet inside and a rubber sleeve outside, and the scraper 633 and the circular ring 632 maintain a certain inclination angle as a whole, and the inclination angles of adjacent scrapers 633 are opposite, which is helpful to clean impurities on the pipe wall.

[0053] In this embodiment, due to the influence of negative pressure, air and accumulated fluid will flow inside the drainage pipe. The flowing accumulated fluid or air will drive the impeller 634 to rotate. The rotation of the impeller 634 will drive the ring 631 to rotate. The rotation of the ring 631 will drive the scraper 633 to rotate. The scraper 633 will rotate along the inner wall of the drainage pipe 4, and the scraper 633 will also move left and right with the round rod 61, so as to scrape off the mucus adhered to the inner wall of the pipe, prevent the mucus from accumulating for a long time and causing the pipe to be blocked, thereby ensuring the normal flow of the accumulated fluid and making it more convenient to clean the drainage pipe 4 at a later time.

[0054] Please refer again Figure 5 The transmission mechanism 7 includes a transmission rod 71, which is rotatably connected to the bracket, and the bracket is fixed to the inner wall of the protective shell. The ends of the driving rod 12 and the transmission rod 71 that are close to each other are connected to bevel gears 72, and the two bevel gears 72 are meshed for transmission. The upper end of the transmission rod 71 is fixedly connected to a shifting rod 73, one end of the round rod 61 is rotatably connected to a pin shaft rod 1 74, one end of the shifting rod 73 is rotatably connected to a pin shaft rod 2 75, one end of the pin shaft rod 1 74 is rotatably connected to a rotating rod 76, and the other end of the rotating rod 76 is rotatably connected to the pin shaft rod 2 75.

[0055] In this embodiment, the bevel gear 72 on the driving rod 12 and the transmission rod 71 meshes with each other to drive the transmission rod 71 to rotate. The rotation of the transmission rod 71 drives the lever 73 to make uniform circular motion along the central axis of the transmission rod 71, and the rotating rod 76 on the pin shaft rod 75 rotates with the lever 73. At this time, the other end of the rotating rod 76 makes reciprocating motion. Since one end of the round rod 61 is connected to one end of the rotating rod 76 through the pin shaft rod 1 74, the round rod 61 can move back and forth with the rotating rod 76 (specifically, the round rod 61 and the housing 3 use a piston-style plug-in method, which can limit the movement direction of the round rod 61 and ensure sealing while ensuring sliding).

[0056] Please also read Figure 1-4 A connecting piece 9 is provided between the drainage pipe 4 and the connecting head 8, and the connecting piece 9 includes a plug 1 91 and a plug 2 92. The plug 1 91 is connected to the drainage pipe 4, and the plug 2 92 is connected to the connecting head 8. The outer wall of the plug 1 91 is slidably connected with a sleeve 93, and a compression spring 94 is connected between the sleeve 93 and the plug 1 91. The outer wall of the plug 2 92 is fixedly sleeved with a docking ring 95. A through hole is opened in a ring-shaped distribution at one end of the plug 1 91, and the through hole is filled with steel balls 96. The inner wall of the plug 1 91 is also connected with a clamping ring 1 97 and a clamping ring 2 98, wherein a sealing ring is provided on one side of the docking ring 95, a sealing ring is provided on one side of the clamping ring 1 97, and the clamping ring 2 98 is made of medical silicone rubber.

[0057] In this embodiment, when connecting the connector 8 and the drainage pipe 4, the sleeve 93 is first moved to the right and the compression spring 94 is compressed, and then the second plug 92 is inserted into the inside of the plug 1 91. During the process of the second plug 92 entering the inside of the plug 1 91, the steel ball 96 is squeezed outward. When the second plug 92 is completely inserted into the inside of the plug 1 91, the user loosens the sleeve 93, and then relies on the reset force generated by the compression spring 94 to drive the sleeve 93 to reset. During the reset process, the sleeve 93 squeezes the steel ball 96 inward, so that the steel ball 96 is embedded in the connector 8 and the drainage pipe 4 is connected. The connection is completed by limiting the position in the groove on the connecting ring 95. Conversely, when disassembly is required, the sleeve 93 is moved to the right in the same way. At this time, the steel ball 96 loses its resistance, and the plug 2 92 can be pulled out from the plug 1 91. After the plug 1 91 and the plug 2 92 are fully docked, the inserted end of the plug 2 92 is tightly in contact with the clamping ring 2 98, and the sealing ring on one side of the docking ring 95 is just embedded in the sealing groove on one side of the clamping ring 1 97, which effectively ensures the sealing and prevents air leakage at the connection, thereby ensuring the suction.

[0058] The working principle of the present invention is:

[0059] The drainage hose is connected to the connector 8, and the drainage hose is inserted into the chest cavity of the patient. The air is extracted by the negative pressure device to generate negative pressure inside the chest cavity. Under the action of the negative pressure, the effusion inside the chest cavity of the patient is drawn in along the external drainage hose, the connector 8 and the drainage pipe 4, and then the effusion falls from the shell 3 into the screening box 2. The effusion is filtered by the filter plate inside the screening box 2, and the effusion flows into the frame 1, while the impurities in the effusion are blocked, and then transported by the auger conveying blades 13, and then fall into the collection box 10.

[0060] The driving unit 5 is started to drive the driving rod 12 to rotate so that the auger conveying blade 13 rotates (the driving unit 5 can be an electric motor), and the auger conveying blade 13 drives the filtered impurities to move to the left, and the driving rod 12 and the bevel gear 72 on the transmission rod 71 are meshed and driven to drive the transmission rod 71 to rotate. The rotation of the transmission rod 71 drives the lever 73 to make uniform circular motion along the central axis of the transmission rod 71, and the rotating rod 76 on the pin shaft rod 75 rotates with the lever 73. At this time, the other end of the rotating rod 76 reciprocates. Since one end of the round rod 61 is connected to one end of the rotating rod 76 by the pin shaft rod 1 74, the round rod 61 can move back and forth with the rotating rod 76 (specifically, the round rod 61 and the housing 3 use a piston-style plug-in method, which can limit the movement direction of the round rod 61, and ensure sealing while ensuring sliding);

[0061] When the round rod 61 moves left and right, it drives the support frame 624 to move left and right. The tooth grooves on the support frame 624 mesh with the gear 1 622, so that the gear 1 622 drives the rotating rod 621 to rotate. The rotating rod 621 rotates to drive the crushing blades 623 at both ends to rotate to crush the impurities in the effluent, reduce the volume of the impurities in the effluent, increase the flow rate of the effluent, and avoid accumulation or blockage caused by excessive volume of impurities.

[0062] Due to the influence of negative pressure, air and accumulated fluid will flow inside the drainage pipe, and the flowing accumulated fluid or air will drive the impeller 634 to rotate, and the rotation of the impeller 634 will drive the ring 631 to rotate, and the rotation of the ring 631 will drive the scraper 633 to rotate. The scraper 633 will rotate along the inner wall of the drainage pipe 4, and the scraper 633 will also move left and right with the round rod 61, so as to scrape off the mucus adhered to the inner wall of the pipe, and prevent the mucus from clogging the pipe due to long-term accumulation, thereby ensuring the normal flow of the accumulated fluid and making it more convenient to clean the drainage pipe 4 later.

[0063] By setting the connector 9, when connecting the connector 8 and the drainage pipe 4, first move the sleeve 93 to the right and squeeze the compression spring 94, then insert the second plug 92 into the first plug 91. During the process of the second plug 92 entering the first plug 91, the steel ball 96 will be squeezed outward. When the second plug 92 is completely inserted into the first plug 91, the user loosens the sleeve 93, and then relies on the reset force generated by the compression spring 94 to drive the sleeve 93 to reset. During the reset process, the sleeve 93 will squeeze the steel ball 96 inward, so that the steel ball 96 is embedded in the connector 8 and the drainage pipe 4 is connected. The connection is completed by limiting the position in the groove on the connecting ring 95. Conversely, when disassembly is required, the sleeve 93 is moved to the right in the same way. At this time, the steel ball 96 loses its resistance, and the plug 2 92 can be pulled out from the plug 1 91. After the plug 1 91 and the plug 2 92 are fully docked, the inserted end of the plug 2 92 is tightly in contact with the clamping ring 2 98, and the sealing ring on one side of the docking ring 95 is just embedded in the sealing groove on one side of the clamping ring 1 97, which effectively ensures the sealing and prevents air leakage at the connection, thereby ensuring the suction.

[0064] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
