Description

Technical Field

[0001] The present invention relates to the technical field of medical device cleaning and nursing, and particularly to a reusable and traceable venous port nursing package. Background Art

[0002] With the development of medical technology, this device is used in the cleaning and nursing of venous port-related equipment. Venous ports are often used in long-term infusion, chemotherapy and other treatment processes in medicine. It is crucial to clean and care for them. This device can effectively clean, maintain and manage the venous port nursing package, ensure the normal use of the venous port, reduce the risk of infection, and improve the quality and safety of medical care.

[0003] However, there are still many defects in venous port nursing packages with similar structures during actual use. For example, the cleaning parts of existing venous port nursing packages may not be thoroughly cleaned, it is difficult to collect impurities during the cleaning process, it is easy to cause secondary pollution, and the cleaning area will be re-polluted when the cleaning parts return to their positions. At the same time, existing venous port nursing packages may lack an accurate opening and closing control mechanism and cannot accurately control the opening and closing of the collection channel. This may result in ineffective collection of impurities generated during the cleaning process, or dust easily re-entering the cleaning area after collection, causing cyclic pollution of impurities inside the nursing package, affecting the cleaning efficiency and reliability, and increasing the risk of infection. Therefore, it is necessary to design a reusable and traceable venous port nursing package. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a reusable and traceable venous port nursing package.

[0005] The present invention is realized by the following technical solutions: A reusable and traceable venous port nursing package, including an installation component, the installation component includes a nursing box, a protective cabinet is rotatably installed on the outer surface of the nursing box, a traceability positioning piece is fixedly installed on the outer surface of the protective cabinet, and further includes:

[0006] A collection component, the collection component includes a collection box fixedly installed on the inner wall of the nursing box, a feed port is opened on the outer surface of the collection box, a baffle is arranged inside the collection box, and a semi-toothed gear is arranged on the outer surface of the baffle;

[0007] A storage component, the storage component includes a storage box fixedly installed on the outer surface of the collection box, discharge ports are opened on both sides of the storage box, and a limiting rod is fixedly installed inside the storage box;

[0008] A cleaning component, the cleaning component includes a partition plate slidably installed on the outer surface of the limiting rod, a first bevel gear is rotatably installed on the outer surface of the partition plate through a first mounting plate, and a cleaning brush is arranged at the bottom of the first bevel gear;

[0009] An auxiliary component, the auxiliary component includes a connecting rod arranged on one side of the first bevel gear, and a driving rack meshing with the half-tooth gear is fixedly connected to the bottom of the connecting rod.

[0010] As a further improvement of the above solution, a limiting plate is fixedly installed on the outer surface of the collection box, and a storage box is fixedly installed on the top of the limiting plate.

[0011] Through the above technical solution, through this stable connection, during the use of the entire care package, the storage box will not easily shake or shift, thus ensuring that components such as the cleaning components inside the storage box can work properly, avoiding problems such as incomplete cleaning or component damage that may be caused by component shaking, and indirectly improving the cleaning efficiency and reliability of the care package.

[0012] As a further improvement of the above solution, a mounting rod is fixedly installed inside the collection box, a baffle is sleeved on the outer surface of the mounting rod, and a half-tooth gear is fixedly connected to the outer surface of the baffle.

[0013] Through the above technical solution, during the cleaning process, the accurate rotation of the baffle is crucial for controlling the opening and closing of the internal passage of the collection box, thus ensuring that impurities can smoothly enter the collection box and preventing dust from flowing back, which helps to achieve the effects of effectively collecting impurities and preventing impurity backflow.

[0014] As a further improvement of the above solution, a limiting rack is fixedly installed on the inner wall of the storage component, a limiting rod fixedly installed on the inner wall of the storage box is arranged at the top of the limiting rack, a moving seat is sleeved on the outer surface of the limiting rod, a partition plate is fixedly installed on the top of the moving seat, and an object-taking groove is opened inside the partition plate.

[0015] Through the above technical solution, the partition plate can stably slide along a predetermined trajectory under the action of these two structures, thus ensuring the accurate meshing of the driving gear on the outer surface of the partition plate with the limiting rack, and then driving the subsequent cleaning components to work properly, realizing the effective cleaning of the inner wall of the storage box. At the same time, the object-taking groove inside the partition plate facilitates the staff to operate the sliding of the partition plate, improving the convenience of operation.

[0016] As a further improvement of the above solution, a driving gear is rotatably installed on the outer surface of the partition plate, the driving gear meshes with the limiting rack, first mounting plates are fixedly installed on both sides of the outer surface of the partition plate, and a first bevel gear is rotatably installed inside the first mounting plates.

[0017] Through the above technical solution, the force for the staff to slide the partition board can be converted into the rotational power required by the cleaning components, achieving effective energy transfer and ensuring that the cleaning brush and the cleaning roller can rotate normally to clean the inner wall of the storage box.

[0018] As a further improvement of the above solution, a rotating rod is fixedly connected to the bottom of the first bevel gear, and cleaning brushes are evenly fixedly connected to the outer surface of the rotating rod. On one side of the first mounting plate, there are second mounting plates fixedly installed on both sides of the outer surface of the partition board.

[0019] Through the above technical solution, the cleaning brushes are evenly distributed on the outer surface of the rotating rod, which can comprehensively cover the cleaning area of the inner wall of the storage box, improving the cleaning effect. At the same time, the setting of the second mounting plate provides a basis for the installation of subsequent components such as the cleaning roller, further improving the structure of the cleaning assembly and enabling it to clean the inner wall of the storage box from different angles.

[0020] As a further improvement of the above solution, a cleaning roller is rotatably installed inside the second mounting plate, and a second bevel gear is fixedly connected to the side of the cleaning roller away from the second mounting plate. The second bevel gear meshes with the first bevel gear.

[0021] Through the above technical solution, the cleaning roller rotates through the meshing relationship with the first bevel gear and jointly cleans the inner wall of the storage box with the cleaning brushes. The rotation of the cleaning roller increases the cleaning methods and scope, and cooperates with the cleaning brushes to clean the inner wall of the storage box more thoroughly, improving the cleaning efficiency and quality.

[0022] As a further improvement of the above solution, a connecting rod is fixedly installed on the outer surface of the second mounting plate, and a driving rack is fixedly connected to the bottom of the connecting rod. The driving rack meshes with the semi-toothed gear.

[0023] Through the above technical solution, it is ensured that the internal passage of the collection box can be opened and closed in a timely manner at different stages of the cleaning operation, realizing the effective collection of impurities during the cleaning process and preventing dust from flowing back, ensuring the smooth progress of the entire cleaning process inside the care package, and improving the coordination and overall efficiency of the cleaning operation.

[0024] As a further improvement of the above solution, first scraping plates are fixedly installed on both sides of the outer surface of the partition board, and the first scraping plates correspond to the second bevel gears.

[0025] Through the above technical solution, the presence of the first scraping plates can prevent the dust on the surface of the cleaning roller from re-polluting the inner wall of the storage box during the retraction process, effectively improving the thoroughness of cleaning, maintaining the cleanliness of the inner wall of the storage box, being conducive to extending the cleaning cycle of the care package, and reducing the frequency of frequent cleaning.

[0026] As a further improvement of the above solution, a second scraping plate is provided at the bottom of the first scraping plate, and the second scraping plate is fixedly installed on both sides of the outer surface of the partition plate, and the second scraping plate is disposed on the outer surface of the inner wall of the storage box.

[0027] Through the above technical solution, acting together with the first scraping plate, the cleaning effect is further improved, the dust in the cleaning process is processed from different angles, the cleanliness inside the care package is ensured, which helps to improve the reusability of the care package and reduce the medical risks that may be caused by insufficient cleaning.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0029] In the present invention, through the structural operation of scraping the surface of the cleaning roller by the first scraping plate and scraping the outer surface of the inner wall of the storage box by the second scraping plate, after the cleaning process is completed, when the cleaning assembly returns to its original position, the first scraping plate can accurately scrape off the dust adhered to the cleaning roller during the cleaning process, and the presence of the first scraping plate can prevent the dust from re-polluting the inner wall of the storage box during the return process. At the same time, the second scraping plate directly acts on the outer surface of the inner wall of the storage box to ensure that there is no dust residue on the inner wall of the storage box after the entire cleaning process. This design of the double scraping plates processes the dust in the cleaning process from different angles, not only improves the effect of single cleaning, but also enables the cleanliness inside the care package to be maintained for a long time, reduces the need for frequent deep cleaning, thus achieving the effect of easy cleaning, and effectively prevents the secondary pollution of the inner wall of the storage box by dust during the return process of the cleaning assembly, and prolongs the service life of the care package.

[0030] When the partition plate slides in the storage box in the present invention, the connecting rod fixedly installed on the outer surface of the second mounting plate will move along with it. When the connecting rod moves into the collection box, the driving rack fixedly connected to the bottom of the connecting rod meshes with the semi-toothed gear on the outer surface of the baffle in the collection box, thereby driving the baffle to rotate. When the partition plate is moved to the edge inside the storage box, the baffle will rotate to a specific position, thereby opening the channel inside the collection box. At this time, the impurities generated during the cleaning process can smoothly enter the collection box along with the rotation of the cleaning roller, realizing the effective collection of the impurities generated during the cleaning process. Due to the meshing relationship between the driving rack and the semi-toothed gear, the baffle will rotate in the reverse direction and close. This precise opening and closing control mechanism ensures that the dust will not re-enter the storage box through the feeding port of the collection box, preventing the backflow of impurities. This design ensures the clean environment inside the storage box, enables the storage box to continuously provide a clean working space for the cleaning assembly, is beneficial to the next cleaning operation, and also avoids the cyclic pollution of impurities inside the care package, improving the cleaning efficiency and reliability of the entire venous port care package.

Detailed implementation manners

[0042] Next, in combination with the accompanying drawings and specific implementation manners, the present invention will be further described. It should be noted that, on the premise of no conflict, any combination of the following described embodiments or technical features can form a new embodiment.

[0043] Embodiment:

[0044] Please combine with Figures 1-9 , a reusable and traceable venous port care package according to this embodiment includes an installation component 1. The installation component 1 includes a care box 101, a protective cabinet 102 is rotatably installed on the outer surface of the care box 101, and a traceability positioning piece 103 is fixedly installed on the outer surface of the protective cabinet 102. It also includes:

[0045] A collection component 2. The collection component 2 includes a collection box 201 fixedly installed on the inner wall of the care box 101. A feed port 202 is opened on the outer surface of the collection box 201. A baffle 205 is arranged inside the collection box 201, and a semi-toothed gear 206 is arranged on the outer surface of the baffle 205;

[0046] A storage component 3. The storage component 3 includes a storage box 301 fixedly installed on the outer surface of the collection box 201. Discharge ports 302 are opened on both sides of the storage box 301, and a limiting rod 304 is fixedly installed inside the storage box 301;

[0047] A cleaning component 4. The cleaning component 4 includes a partition plate 402 slidably installed on the outer surface of the limiting rod 304. A first bevel gear 406 is rotatably installed on the outer surface of the partition plate 402 through a first mounting plate 405, and a cleaning brush 408 is arranged at the bottom of the first bevel gear 406;

[0048] An auxiliary component 5. The auxiliary component 5 includes a connecting rod 501 arranged on one side of the first bevel gear 406, and a driving rack 502 meshing with the semi-toothed gear 206 is fixedly connected to the bottom of the connecting rod 501.

[0049] A limiting plate 203 is fixedly installed on the outer surface of the collection box 201, and a storage box 301 is fixedly installed on the top of the limiting plate 203.

[0050] An installation rod 204 is fixedly installed inside the collection box 201. The outer surface of the installation rod 204 is sleeved with a baffle 205, and a semi-toothed gear 206 is fixedly connected to the outer surface of the baffle 205.

[0051] Due to this meshing relationship, the movement of the driving rack 502 will drive the semi-toothed gear 206 to rotate, and then drive the baffle 205 to rotate. When the partition plate 402 is moved to the edge inside the storage box 301, the baffle 205 will rotate to a specific position, thereby opening the channel inside the collection box 201. At this time, the impurities generated during the cleaning process can enter the collection box 201 as the cleaning roller 410 rotates.

[0052] The inner wall of the storage component 3 is fixedly installed with a limit rack 303. At the top of the limit rack 303, there is a limit rod 304 fixedly installed on the inner wall of the storage box 301. A moving seat 401 is sleeved on the outer surface of the limit rod 304. A partition plate 402 is fixedly installed on the top of the moving seat 401. An object-taking slot 403 is formed inside the partition plate 402.

[0053] A driving gear 404 is rotatably installed on the outer surface of the partition plate 402. The driving gear 404 meshes with the limit rack 303. On both sides of the outer surface of the partition plate 402, first mounting plates 405 are fixedly installed. A first bevel gear 406 is rotatably installed inside the first mounting plates 405.

[0054] The bottom of the first bevel gear 406 is fixedly connected to a rotating rod 407. Cleaning brushes 408 are evenly fixedly connected to the outer surface of the rotating rod 407. On one side of the first mounting plate 405, second mounting plates 409 are fixedly installed on both sides of the outer surface of the partition plate 402.

[0055] A cleaning roller 410 is rotatably installed inside the second mounting plate 409. On the side of the cleaning roller 410 away from the second mounting plate 409, a second bevel gear 411 is fixedly connected. The second bevel gear 411 meshes with the first bevel gear 406.

[0056] As the driving gear 404 rotates, it will drive the first bevel gear 406 to rotate. Due to the meshing relationship between the first bevel gear 406 and the second bevel gear 411, the cleaning roller 410 is driven to rotate. At the same time, the rotating rod 407 fixedly connected to the bottom of the first bevel gear 406 has cleaning brushes 408 evenly fixedly connected to its outer surface. The rotation of the first bevel gear 406 will also drive the cleaning brushes 408 to rotate. The rotation of the cleaning brushes 408 and the cleaning roller 410 will clean the outer surface of the inner wall of the storage box 301.

[0057] A connecting rod 501 is fixedly installed on the outer surface of the second mounting plate 409. The bottom of the connecting rod 501 is fixedly connected to a driving rack 502. The driving rack 502 meshes with the semi-tooth gear 206.

[0058] On both sides of the outer surface of the partition plate 402, first scraping plates 503 are fixedly installed. The first scraping plates 503 correspond to the second bevel gears 411.

[0059] At the bottom of the first scraping plate 503, second scraping plates 504 are fixedly installed on both sides of the outer surface of the partition plate 402. The second scraping plates 504 are arranged on the outer surface of the inner wall of the storage box 301.

[0060] The first scraping plate 503 can effectively avoid this situation. The second scraping plate 504 directly acts on the outer surface of the inner wall of the storage box 301. After the entire cleaning process, it can ensure that no dust remains on the outer surface of the inner wall of the storage box 301, further improving the cleanliness inside the care package and ensuring the cleanliness and reusable performance of the care package.

[0061] In the embodiment of the present application, the implementation principle of a reusable and traceable venous port care package is as follows: The staff slides the cleaning component 4 in the storage component 3 through the object-taking slot 403 inside the partition plate 402. When the partition plate 402 slides along the limiting rod 304 in the storage box 301, the driving gear 404 on the outer surface of the partition plate 402 meshes with the limiting rack 303 on the inner wall of the storage box 301. Due to this meshing relationship, as the partition plate 402 slides, the driving gear 404 will rotate;

[0062] During the cleaning process, when the cleaning component 4 completes the cleaning operation and returns to its original position, the function of the first scraping plate 503 is to scrape the surface of the cleaning roller 410. Since the cleaning roller 410 may adhere to dust during the cleaning process, if not scraped, this dust may re-pollute the outer surface of the inner wall of the storage box 301 during the return process. The first scraping plate 503 can effectively avoid this situation. The second scraping plate 504 directly acts on the outer surface of the inner wall of the storage box 301. After the entire cleaning process, it can ensure that no dust remains on the outer surface of the inner wall of the storage box 301, further improving the cleanliness inside the care package and ensuring the cleanliness and reusable performance of the care package;

[0063] When the partition plate 402 slides in the storage box 301, the connecting rod 501 fixedly installed on the outer surface of the second mounting plate 409 will also move accordingly. When the connecting rod 501 moves into the collection box 201, the driving rack 502 fixedly connected to the bottom of the connecting rod 501 meshes with the semi-tooth gear 206 on the outer surface of the baffle 205 in the collection box 201. Due to this meshing relationship, the movement of the driving rack 502 will drive the semi-tooth gear 206 to rotate, and then drive the baffle 205 to rotate. When the partition plate 402 is moved to the edge inside the storage box 301, the baffle 205 will rotate to a specific position, thereby opening the channel inside the collection box 201. At this time, the impurities generated during the cleaning process can enter the collection box 201 as the cleaning roller 410 rotates. When the partition plate 402 leaves its original position, that is, moves away from the position on the edge inside the storage box 301, due to the meshing relationship between the driving rack 502 and the semi-tooth gear 206, the baffle 205 will rotate in the reverse direction to close, ensuring that dust will not re-enter the inside of the storage box 301 through the feed port 202 of the collection box 201;

[0064] During the whole process, the installation component 1 provides a basic structural framework for the whole care package. The traceability positioning piece 103 on the outer surface of the protection cabinet 102 can be used for the traceability function of the care package. The collection component 2 is responsible for collecting impurities during the cleaning process. The baffle 205 inside it realizes opening and closing control under the action of the auxiliary component 5. The storage component 3 provides a working space for the cleaning component 4 and interacts with the cleaning component 4 through structures such as the limit rack 303. The cleaning component 4 cleans the inner wall of the storage component 3 under the operation of the staff and drives the cleaning part to rotate through the transmission of its own structure. The auxiliary component 5 plays a role in connecting the cleaning component 4 and the collection component 2 to realize the linkage between the two, ensuring the effective realization of functions such as cleaning, collection and preventing impurity backflow during the use of the whole care package;

[0065] It should be specifically noted here that the traceability positioning piece 103 can adopt a GPS locator with the model of "F35D" in the Aerospace Zijin brand, which can be used for the traceability function of the care package.

[0066] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the scope of protection required by the present invention.
