Description

Technical Field

[0001] The invention relates to the technical field of waste liquid collection, in particular to a waste liquid collection device based on operating room care. Background Art

[0002] Arthroscopic surgery requires isotonic saline to be injected into the joint cavity at a certain pressure, so that the surgeon can obtain vision and surgical operation space in the liquid environment formed. During arthroscopic surgery, liquid will continuously seep out from around the skin entrance of the arthroscope and spread to the operating table and its surroundings. At this time, the waste liquid needs to be collected through the waste liquid collection tank to prevent the waste liquid from polluting the surgical environment.

[0003] For example, the patent with Chinese utility model publication number CN219440178U has a filter plate fixedly connected to the bottom of the collecting trough body. The waste liquid and garbage in the deflector entering the collecting trough body can fall into the top of the filter plate inside the collecting trough body. At this time, the waste liquid can fall into the bottom of the collecting trough body through the filter plate. At this time, the threaded rod can be driven to rotate by starting the rotating motor. The threaded block on the threaded rod can move on the threaded rod. At the same time, the threaded block can push the push plate to move on the top of the filter plate through the connecting block, and clean the garbage on the top of the filter plate, thereby improving the overall functionality of the surgical waste liquid collection trough. However, in actual use, its cleaning method is relatively single, and when the garbage is stuck in the filter hole on the filter plate, the push plate cannot play a cleaning effect, which has certain limitations and is inconvenient to use.

[0041] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0042] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0043] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0044] In addition, in this application, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0045] During arthroscopic surgery, isotonic saline is injected into the joint cavity at a certain pressure, allowing the surgeon to gain vision and surgical operating space in the liquid environment formed. During the operation, the collection device is aimed at the position where the arthroscopic surgery is drained to collect and treat the surgical waste fluid.

[0046] In the related art, a filter plate is fixedly connected to the bottom end of the collecting trough body, so that the waste liquid and garbage entering the collecting trough body through the deflector can fall into the top of the filter plate inside the collecting trough body. At this time, the waste liquid can fall into the bottom end of the collecting trough body through the filter plate. At this time, the threaded rod can be driven to rotate by starting the rotating motor, and the threaded block on the threaded rod can move on the threaded rod. At the same time, the threaded block can push the push plate to move on the top of the filter plate through the connecting block, and clean the garbage on the top of the filter plate, thereby improving the overall functionality of the surgical waste liquid collection trough. However, in actual use, the cleaning method is relatively simple, and when the garbage is stuck in the filter hole on the filter plate, the push plate cannot play a cleaning effect, which has certain limitations and is inconvenient to use.

[0047] In order to solve the problems in the related technology to a certain extent, the embodiment of the present application provides a waste liquid collection device based on operating room care. When in use, it is only necessary to align the collection box 11 with the drainage position of the arthroscopic surgery to collect and process the surgical waste liquid, filter the waste liquid through the filter plate 22, and slide the filter plate 22 up and down, or turn on the electric push rod 41 to make the cleaning mechanism 25 clean the filter plate 22, which is more convenient and quick, and improves the convenience of the device.

[0048] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0049] Combination Figure 1-Figure 6 The embodiment of the present application provides a waste liquid collection device based on operating room nursing, including: a cart 10, a collection box 11 is fixedly connected to the top of the cart 10, a slide rail 20 is fixedly connected to the collection box 11, a frame 21 is slidably connected to the slide rail 20, a filter plate 22 is fixedly connected to the frame 21, a collection box 23 is arranged on one side of the collection box 11, a mounting rod 24 is arranged on the inner side of the collection box 11, a cleaning mechanism 25 is installed on the mounting rod 24, the cleaning mechanism 25 is used to clean the filter plate 22, a limiting mechanism 26 is arranged on the top of the frame 21, the limiting mechanism 26 is used to adjust the height of the frame 21, a drainage mechanism 27 is arranged on the bottom surface of the collection box 11, and the drainage mechanism 27 is used to discharge waste water, a groove body 30 is provided on the collection box 23, and a filter plate 2 31 is fixedly connected in the groove body 30, a mounting plate 40 is provided on one side of the cart 10, and an electric push rod 41 is fixedly connected to the mounting plate 40, a frame body 2 42 is slidably connected to the inner side of the collection box 11, an output end of the electric push rod 41 is fixedly connected to one side of the frame body 2 42, and a rod body 5 43 is fixedly connected to the other side of the frame body 2 42, and the rod body 5 43 is used to clean the filter plate 2 31, a fixed block 50 is fixedly connected to the frame body 2 42, a slide groove 51 is provided on the inner side of the collection box 11, a fixed block 2 52 is slidably connected in the slide groove 51, and the mounting rod 24 is fixedly connected to the fixed block 2 52.

[0050] After pushing the cart 10 and driving the collection box 11 to move to the designated position, the universal wheels at the bottom of the cart 10 are fixed by the foot brake, and the collection box 11 is aligned with the position of the arthroscopic surgery drainage to collect and process the surgical waste liquid. The waste liquid enters the collection box 11, contacts the filter plate 22 on the frame 21, and then filters the waste liquid. Then, the waste liquid containing small-sized garbage or material fragments falls into the collection box 23 along the filter plate 22, and the waste liquid carries the debris and contacts the filter plate 22, so that the filter plate 22 is filtered. 2 generates a downward force, and through the limit mechanism 26, the frame 1 21 is made to slide up and down reciprocatingly in the collection box 11. When the frame 1 21 slides downward, the filter plate 1 22 is brought into contact with the cleaning mechanism 25, and the filter plate 1 22 is cleaned by the cleaning mechanism 25, and the cleaned impurities fall into the collection box 23, completing the collection, filtration and debris cleaning operations of the waste liquid. During the cleaning process, the debris and a small amount of waste liquid fall into the collection box 23, and the waste liquid passes through the filter plate 2 31 on the tank 1 30, so as to prevent the waste liquid from remaining in the collection box 23;

[0051] When collecting waste liquid, the electric push rod 41 is opened, and the output end of the electric push rod 41 extends from the mounting plate 40, while pushing the frame 42 to slide left and right in the collection box 11 (direction reference Figure 2 ), and then the frame body 2 42 pushes the rod body 5 43, so that the rod body 5 43 cleans the filter plate 2 31, thereby preventing the waste liquid from accumulating in the collecting box 23. While the rod body 5 43 cleans the filter plate 2 31, the frame body 2 42 drives the fixed block 1 50 to slide left and right until the fixed block 1 50 contacts the mounting rod 24, and at the same time, pushes the mounting rod 24 and the fixed block 2 52 to slide up and down in the slide groove 51, so that the mounting rod 24 drives the cleaning mechanism 25 to slide up and down, and then the cleaning mechanism 25 actively cleans the filter plate 1 22, thereby improving practicality.

[0052] In some embodiments, a baffle plate 111 is fixedly connected to the interior of the collection box 11, so that the baffle plate 111 can guide the waste liquid and facilitate filtering by the filter plate 22.

[0053] In some embodiments, the frame 21 is tilted to facilitate the impurities filtered by the filter plate 22 to fall into the collection box 23.

[0054] In some embodiments, the cleaning mechanism 25 includes: a rod body 1 251 fixedly connected to the outer side of the mounting rod 24 ; and a rod body 252 fixedly connected to the outer side of the rod body 1 251 .

[0055] When the cleaning mechanism 25 slides up and down, the mounting rod 24 drives the rod body 252 and the rod body 1 251 to slide up and down, so that the rod body 252 is raised to clean the filter plate 1 22, or when the frame body 1 21 slides downward, the rod body 252 directly cleans the filter plate 1 22 on the frame body 1 21.

[0056] In some embodiments, one end of the rod body 252 and the rod body 5 43 are fixedly connected with a sphere, so that the spheres on the end faces of the rod body 252 and the rod body 5 43 are first inserted into the filter plate 1 22 and the filter plate 2 31, thereby facilitating the cleaning of the filter plate 1 22 and the filter plate 2 31.

[0057] In some embodiments, the drainage mechanism 27 includes: a funnel 271 fixedly connected to the inner side of the collection box 11; a tube body 272 is arranged at the bottom of the funnel 271, and the other end of the tube body 272 passes through the collection box 11; a sealing cover 273 is threadedly connected to the outer end of the tube body 272.

[0058] After filtering the waste liquid, the waste liquid falls into the funnel 271 , and finally the sealing cover 273 is opened to directly discharge the waste liquid through the tube body 272 .

[0059] In some embodiments, a cavity 60 is opened on the collection box 11, and a plate body 61 is slidably connected in the cavity 60. A spring 2 62 is arranged in the cavity 60, and the two ends of the spring 2 62 are respectively fixedly connected to the plate body 1 61 and the collection box 11, and a plate body 2 63 is fixedly connected to one side of the plate body 1 61, and the top of the plate body 1 61 is inserted into the mounting plate 40.

[0060] When the mounting plate 40 needs to be disassembled, the plate body 2 63 is pulled downward so that the plate body 2 63 drives the plate body 1 61 to slide downward in the cavity 60, and the spring 2 62 is pulled until the top of the plate body 1 61 slides out of the mounting plate 40. After the limit on the mounting plate 40 is cancelled, the mounting plate 40 is directly pulled outward so that the mounting plate 40 drives the upper structure thereof to slide out of the collection box 11 to achieve disassembly, and vice versa to achieve installation.

[0061] In some embodiments, the frame body 42 is fixedly connected to a rod body 60, and a groove body 71 is provided on one side of the plate body 61. When the electric push rod 41 is turned on, the frame body 42 slides left and right (direction reference Figure 2 ), clean the filter plate 2 31, otherwise the frame body 2 42 drives the rod body 6 70 to slide toward the plate body 1 61, and then the rod body 6 70 contacts the groove body 2 71 on the plate body 1 61, thereby pushing the plate body 1 61 to slide downward, and finally the plate body 1 61 slides out from the mounting plate 40, thereby unlocking the mounting plate 40, thereby facilitating the disassembly of the mounting plate 40.

[0062] In some embodiments, the limiting mechanism 26 includes: a rod body 3 261 fixedly connected to the top of the frame body 21; a rod body 4 262 slidably connected inside the rod body 3 261; a ring body 263 fixedly connected to the outside of the rod body 3 261; a spring 1 264 is sleeved on the outside of the rod body 4 262, and the two ends of the spring 1 264 are respectively fixedly connected to the collection box 11 and the ring body 263.

[0063] When the frame 21 slides downward, the frame 21 pulls the rod body 3 261 to slide downward. While sliding, the rod body 3 261 slides out from the rod body 4 262. At the same time, the rod body 3 261 drives the ring body 263 to slide and pulls the spring 1 264. Then, through the rebound force of the spring 1 264, the ring body 263 and the rod body 3 261 slide upward and reset, while pulling the frame 21 to slide upward, so as to facilitate the vibration screening operation of the waste liquid.

[0064] In some embodiments, the tank body 1 30 and the filter plate 2 31 are a group, and multiple groups are arranged on the collection box 23, so that the collection box 23 can discharge waste liquid through multiple filter plates 2 31.

[0065] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", "some examples", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application.

Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification.
