Description

Technical Field

[0001] This application relates to the field of medical device accessories technology, and in particular to a portable medical nasal cannula storage structure. Background Technology

[0002] Nasal cannulas are a core medical consumable used in clinical medicine for oxygen therapy in patients. They are widely used in various medical scenarios such as hospital wards, emergency rooms, and outpatient clinics. They are used frequently and in large quantities. They also have strict requirements for sterility, dryness, and ease of use during storage. Nasal cannulas are prone to softening and mold growth if they get damp. If they are contaminated, they may cause cross-infection in patients. If they are stored in a disorderly manner, it will increase the workload of medical staff in sorting and retrieving them, and affect the efficiency of clinical diagnosis and treatment.

[0003] The main body of existing storage carts is mostly made of ordinary plastic or metal, without the use of special medical-grade materials. They do not have good corrosion resistance and biocompatibility, are prone to bacterial growth, and are heavy. They also lack convenient movement structures. Even if some carts are equipped with wheels, they often do not have braking mechanisms, which can easily cause them to shift during the diagnosis and treatment process, affecting the operation of medical staff.

[0004] Storage drawers are mostly ordinary open or simple closed designs, without a special moisture-proof structure on the inner wall, and the bottom of the drawer is not equipped with moisture-absorbing and moisture-proof components. When the ambient humidity is high, moisture can easily penetrate into the drawer, causing the nasal cannula to become damp and moldy, damaging the structural integrity and safety of the nasal cannula.

[0005] The existing storage devices have unreasonable disinfection structure designs. Most of them do not have dedicated layered disinfection components, which makes it impossible to achieve precise and thorough disinfection of the nasal cannulas in each layer of storage drawers. The disinfection effect is poor, and it is difficult to effectively prevent the nasal cannulas from being contaminated by bacteria during storage, thus failing to meet the medical sterility requirements.

[0006] Therefore, a portable medical nasal cannula storage structure is proposed. Summary of the Invention

[0007] This application aims to at least partially solve one of the technical problems in the aforementioned technologies.

[0008] To achieve the above objectives, the first aspect of this application proposes a portable medical nasal cannula storage structure, including a trolley body with a slot at its front end;

[0009] The slotted interior is equipped with several storage drawers installed from top to bottom. Compared with the existing simple drawer installation method, the installation is more secure and the positioning is more accurate, avoiding loosening or displacement of the drawers during use. At the same time, it optimizes the overall structural layout of the trolley, improves the neatness of storage, and the storage drawers are arranged in layers from top to bottom, which can realize the classified storage of nasal cannulas of different specifications and uses, avoid confusion, reduce the workload of medical staff in finding them, and improve the efficiency of clinical retrieval.

[0010] The storage drawer is equipped with a storage tray, and the outer circle of the storage tray has a winding groove, which can guide the nasal cannula to wind in an orderly manner, solving the problems of loosening, messy winding, and falling off of the nasal cannula caused by the lack of a regular winding structure in the existing storage tray, while avoiding damage to the nasal cannula due to winding and pulling.

[0011] The storage drawer is equipped with a small UV-C ultraviolet disinfection lamp at the bottom for disinfecting the lower drawer. This targeted disinfection of the lower drawer allows for precise layered disinfection. Compared to existing structures that do not offer layered disinfection or only disinfect the entire drawer, this method is more targeted and leaves no blind spots. It effectively kills bacteria on the surface of the nasal cannula, reduces the risk of cross-infection, and meets medical sterility requirements.

[0012] In addition, the portable medical nasal cannula storage structure proposed in this application may also have the following additional technical features:

[0013] As a further description of the above technical solution:

[0014] The main body of the trolley is integrally injection molded from medical-grade ABS material, ensuring no contamination when in contact with medical consumables such as nasal cannulas, thus guaranteeing the safety of medical use. It solves the defects of existing trolleys made of ordinary plastic and metal materials, which are prone to bacterial growth and do not meet medical standards. It has good corrosion resistance and impact resistance and can withstand wiping and disinfection by commonly used hospital disinfectants (alcohol, chlorine-containing disinfectants, etc.).

[0015] As a further description of the above technical solution:

[0016] The trolley is equipped with casters with brakes at the bottom, which makes it easy for medical staff to quickly push the storage structure to the required location such as the ward or emergency bedside. This solves the problem of existing trolleys being inconvenient to move and affecting the efficiency of diagnosis and treatment. The brake function can quickly lock the trolley after it has been moved to the designated position to prevent the trolley from accidentally shifting during diagnosis and treatment.

[0017] As a further description of the above technical solution:

[0018] The inner wall of the storage drawer is coated with a medical-grade moisture-proof coating, forming a dense moisture barrier that effectively prevents external humid air and moisture from entering the drawer. This solves the problem of existing storage drawers lacking moisture-proof structures, which leads to the nasal cannula becoming damp, moldy, and softened, thus ensuring the structural integrity and safety of the nasal cannula.

[0019] As a further description of the above technical solution:

[0020] The medical-grade moisture-proof coating uses modified polyurethane material with a thickness of 0.1-0.2mm. Compared with ordinary moisture-proof coatings, it has superior moisture-proof and waterproof performance, as well as good flexibility and adhesion. It is not easy to fall off or crack and can maintain its moisture-proof effect for a long time, solving the problems of ordinary coatings being easy to fall off and failing in moisture-proofing.

[0021] As a further description of the above technical solution:

[0022] The inner bottom plate of the storage drawer is equipped with a moisture-proof pad. The moisture-proof pad is made of highly absorbent resin material and has a strong moisture absorption capacity. It can quickly absorb trace amounts of moisture inside the drawer (such as moisture from environmental seepage or residual moisture on the surface of the nasal cannula), further supplementing the moisture-proof effect of the inner wall moisture-proof coating.

[0023] As a further description of the above technical solution:

[0024] The storage tray is made of moisture-proof modified PP material, which has good moisture-proof and anti-aging properties. It can effectively isolate water vapor erosion and prevent the storage tray from getting damp and deforming, thus solving the problem that existing storage trays made of ordinary plastic material are prone to moisture and deformation, which in turn contaminates the nasal cannula.

[0025] Advantages of this invention:

[0026] According to this application, a portable medical nasal cannula storage structure is provided. The main body of the trolley is integrally injection molded from medical-grade ABS material and equipped with universal wheels with brakes at the bottom. This ensures structural stability and resistance to medical disinfectant corrosion, while also allowing for flexible movement and fixed-point locking, improving portability and safety. The slotted structure at the front of the trolley body allows for the secure installation of layered storage drawers. The storage tray is made of moisture-proof modified PP material with winding grooves, which can standardize the winding and storage of the nasal cannula, preventing it from being scattered and worn. The inner wall of the storage drawer is coated with a 0.1-0.2mm thick modified polyurethane moisture-proof coating, and the bottom plate is covered with a highly absorbent resin moisture-proof pad, forming double moisture protection, effectively isolating water vapor and absorbing moisture to prevent the nasal cannula from becoming damp and moldy. At the same time, a small UV-C ultraviolet disinfection lamp at the bottom of the storage drawer is used to precisely sterilize and disinfect the lower storage space, reducing the risk of cross-infection. The overall structure combines storage neatness, moisture resistance, sterility, and practicality, and is suitable for the clinical use needs of hospital oxygen consumables storage.

[0027] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0031] Figure 3 This is a schematic diagram of a small UV-C ultraviolet disinfection lamp with a portable medical nasal cannula storage structure according to an embodiment of this application. Detailed Implementation

[0032] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0033] The following description, in conjunction with the accompanying drawings, describes a portable medical nasal cannula storage structure according to an embodiment of this application.

[0034] like Figure 1-3 As shown, a portable medical nasal cannula storage structure according to Embodiment 1 of this application includes a trolley body 1. The trolley body 1 is made of medical-grade ABS material through an integrated injection molding process. The structure is stable and lightweight, making it easy to move and transport. A rectangular slot is opened at the front end of the trolley body 1, and the inner wall of the slot is smoothed for installing a storage drawer 3.

[0035] The slotted interior is equipped with storage drawers 3 installed sequentially from top to bottom. The storage drawers 3 are all the same size and adopt a push-pull structure. Sliding guide rails are set between the two sides of the drawers and the inner wall of the slot to ensure that the drawers can be pushed and pulled smoothly without jamming. Each storage drawer 3 has a simple handle at the front end for easy opening and closing by medical staff. The inner wall of each storage drawer 3 is evenly sprayed with a layer of medical-grade moisture-proof coating. The moisture-proof coating is made of modified polyurethane material and is applied by electrostatic spraying process. The coating thickness is controlled at 0.15mm. After spraying, it is cured at 120℃ to ensure strong adhesion and no peeling, which can effectively prevent external moisture from entering.

[0036] Each storage drawer 3 has a moisture-proof pad on its inner bottom plate, which is made of highly absorbent resin material with a thickness of 5mm and a film coating to prevent moisture from seeping back. The moisture-proof pad can be directly laid on the bottom plate for easy periodic removal and replacement. It can quickly absorb trace amounts of moisture inside the drawer and keep the drawer dry. Each storage drawer 3 has a storage tray 5 fixedly installed inside. The storage tray 5 is fixed to the drawer bottom plate by 4 medical-grade stainless steel fastening bolts to prevent displacement during use. The storage tray 5 is made of moisture-proof modified PP material through injection molding. 5% moisture-proof agent is added to the modified PP material to improve moisture resistance. The storage tray 5 is circular with a diameter of 15cm and a thickness of 2cm. A winding groove 501 is opened around its outer circumference. The winding groove 501 is 1cm wide and 0.8cm deep. The inner wall of the winding groove 501 is smoothed for orderly winding of the nasal cannula to prevent the nasal cannula from becoming loose or tangled.

[0037] Each of the four corners at the bottom of the main body of the trolley 1 is fixed with a universal wheel 2 with brakes by bolts. The universal wheel 2 is made of medical-grade silent rubber material and has a diameter of 10cm. This ensures that the trolley is placed stably after being moved to the designated position and avoids accidental displacement.

[0038] Each storage drawer 3 has a small UV-C ultraviolet disinfection lamp 6 fixedly installed at its bottom via a bracket. The small UV-C ultraviolet disinfection lamp 6 has a wavelength of 270nm and a power of 5W. The disinfection lamp is connected to the bracket at the bottom of the drawer by a snap-fit, which is convenient for disassembly and maintenance. The irradiation range of the small UV-C ultraviolet disinfection lamp 6 completely covers the internal space of the storage drawer 3 below it, so as to achieve precise disinfection of the nasal cannula in the lower drawer. It is connected to the power interface (not shown in the figure) on the side of the trolley body 1 via a wire. The power interface can be connected to the 220V AC power commonly used in hospitals. Each disinfection lamp is equipped with an independent control switch. Medical staff can manually control the start and stop of the disinfection lamp as needed. After the disinfection lamp is turned on, it can effectively kill bacteria and viruses on the surface of the nasal cannula, reduce the risk of cross-infection, and meet the requirements of medical sterility.

[0039] Work process:

[0040] When in use, medical staff can push the main body 1 of the cart and move the storage structure to the required location such as the ward or emergency bedside using the casters 2. Press the brake button on the casters 2 to lock the cart and prevent it from shifting.

[0041] Open the storage drawer 3 of the corresponding size, and neatly wrap the nasal cannula in the winding groove 501 of the storage tray 5. After wrapping, close the storage drawer 3.

[0042] If you need to disinfect the nasal cannula in the lower drawer, you can turn on the small UV-C ultraviolet disinfection lamp 6 at the bottom of the corresponding storage drawer 3, and turn off the switch after disinfection is complete.

[0043] During the storage process, the moisture-proof coating on the inner wall of storage drawer 3 can isolate external moisture, the moisture-proof pad on the bottom plate absorbs trace amounts of internal moisture, and the moisture-proof modified PP material of storage tray 5 can prevent itself from getting damp. The three work together to form double moisture protection to prevent the nasal cannula from getting damp and moldy.

[0044] When the trolley needs to be moved, simply unlock the brakes on the swivel wheels 2 and push the trolley. It is easy to operate and adaptable to the needs of various clinical medical scenarios.
