Description

Technical Field

[0001] The utility model relates to the technical field of medical supplies, in particular to a disposable paraffin oil disinfection cotton swab and a cotton swab assembly. Background Art

[0002] In clinical practice, lightweight liquid paraffin is used for lubrication during catheter insertion and instrument inspection. Currently, lightweight liquid paraffin is stored in large bottles. However, once opened, repeated use can lead to bacterial growth. Lightweight liquid paraffin has a short shelf life after opening, and when used in small quantities, it's possible that the entire bottle may expire even if not fully consumed within its expiration date.

[0003] Currently, disposable iodine swabs, which use hollow, transparent tubes to store liquid medicine, are used clinically to independently package and store small doses of liquid medicine. However, if the liquid medicine is directly replaced with lightweight liquid paraffin, the limited storage capacity of these swabs makes it difficult to fully cover the entire surface of larger instruments. This requires tearing off multiple swabs, adjusting the instrument's position, and wiping multiple times, which increases the instrument's exposure to air and the risk of contamination.

[0004] Therefore, in response to the above-mentioned deficiencies, the present application provides a disposable paraffin oil sterilized cotton swab and a cotton swab assembly to achieve independent packaging of the sterilized cotton swab and paraffin oil combination, and at the same time adjust the amount of paraffin oil in the sterilized cotton swab during use.

Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0029] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0030] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

Such terms are intended solely to facilitate the description of this utility model and simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" and the like are used solely for distinction and description and should not be construed as indicating or implying relative importance.

[0032] This application provides a disposable paraffin oil disinfected cotton swab, such as Figure 1 As shown, it includes: a hollow tube 1, paraffin oil is set in the hollow tube 1, a cotton ball 2 is set at one end of the hollow tube 1, and an elastically deformable sealing component 3 is set at the other end of the hollow tube 1.

[0033] In the lubrication scenarios of instruments of different shapes, the sterile cotton swabs provided in this application can be provided with sterile cotton swabs of hollow tubes of different lengths and diameters to add different doses of paraffin oil, thereby increasing the application range of the sterile cotton swabs of this application. The sealing component 3 and the hollow tube 1 can be separated so that the atmospheric pressure inside and outside the hollow tube 1 is balanced, so that the paraffin oil flows from the hollow tube 1 into the cotton ball 2. Under different paraffin oil dosage requirements, the sealing component 3 and the hollow tube 1 can be completely separated, and the paraffin oil flows into the cotton ball 2 at one time; or the sealing component 3 and the hollow tube 1 can be partially separated so that the opening between the sealing component 3 and the hollow tube 1 is smaller, which is convenient for increasing the sealing speed when resealing, so that the remaining paraffin oil in the hollow tube 1 slows down the speed of flowing into the cotton ball 2 or stops flowing into the cotton ball 2.

[0034] Furthermore, for example Figure 4As shown, the sealing assembly 3 is detachably connected to the end face of the hollow tube 1. The outer diameter of the sealing assembly 3 is greater than or equal to the outer diameter of the hollow tube 1. This seals the hollow tube 1 while reducing dust accumulation on the end face of the hollow tube 1 and lowering the risk of paraffin oil contamination. In another embodiment, the outer diameter of the sealing assembly 3 is greater than the outer diameter of the hollow tube 1. While reducing dust accumulation, a step is formed between the outer circumference of the sealing assembly 3 and the outer circumference of the hollow tube 1. The user presses their fingers against the step to apply force to the sealing assembly 3 away from the hollow tube 1, facilitating separation of the sealing assembly 3.

[0035] Furthermore, for example Figure 1-Figure 3 As shown, the sealing assembly 3 is also provided with a sealing plug 31 extending into the hollow tube 1. The outer diameter of the sealing plug 31 is adapted to the inner diameter of the hollow tube 1, so that the outer circumference of the sealing plug 31 fits the inner circumference of the hollow tube 1, thereby improving the sealing performance. Preferably, the sealing plug 31 is configured as an annular band extending into the hollow tube 1 and surrounding the inner diameter of the hollow tube 1, so that the sealing plug 31 can completely seal the hollow tube 1 360 degrees; at the same time, when the sealing plug 31 contacts the inner wall of the hollow tube 1, the annular sealing plug 31 can be deformed and displaced toward the axial centerline of the hollow tube 1 due to the squeezing of the inner wall, so that the sealing plug 31 can be reset to a sealed state more quickly. In other embodiments, the sealing plug 31 can also be configured to include but not limited to a solid cylinder, a semi-cylinder, and a semi-annular band.

[0036] Furthermore, the contact surface between the hollow tube 1 and the sealing assembly 3 is provided with a support side 32 and an opening side 33, and the support side 32 and the opening side 33 are opposite to each other along the radial direction of the hollow tube 1. The support side 32 of the sealing assembly 3 is provided with a pre-bent portion 4 bent toward the direction inside the hollow tube 1, so that the sealing assembly 3 seals the hollow tube 1 under the prestressed action of the pre-bent portion 4.

[0037] Preferably, one end of the pre-bent portion 4 is disposed on the support side 32, and the other end thereof is disposed on a side of the sealing assembly 3 close to the hollow tube 1 in the radial direction of the hollow tube 1, so that a lever arm is formed between the other end of the pre-bent portion 4 and the support side 32. The user applies an external force from the side of the sealing assembly 3 opposite to the support side 32; the pre-bent portion 4 deforms under the action of the external force perpendicular to the lever arm and in a direction away from the hollow tube 1, driving the sealing assembly 3 to rotate with the connection between the pre-bent portion 4 and the support side 32 as a lever fulcrum, so that the sealing assembly 3 and the hollow tube 1 are separated from the opening side 33, the interior of the hollow tube 1 is connected to the air, and the paraffin oil inside the hollow tube flows into the cotton ball 2 under the action of gravity; after the external force is removed, the sealing assembly 3 automatically reseals the hollow tube 1 under the action of the prestress.

[0038] In further embodiments, the length of the pre-curved portion 4 is greater than or equal to the radius of the sealing assembly 3. A greater prestress in the pre-curved portion 4 improves the sealing capability of the sealing assembly 3; accordingly, after the external force is removed, the pre-curved portion 4 returns to its original position more quickly. In other embodiments, the pre-curved portion 4 is further provided with an elastic sheet or strip having a matching curvature and embedded within the sealing assembly 3.

[0039] This application provides a disposable paraffin oil disinfectant cotton swab with a simple structure and convenient operation. It is suitable for clinical medical scenarios such as catheter insertion and instrument inspection where lubricants are required. The cotton swab comprises a hollow tube pre-filled with lightweight liquid paraffin, which can be kept sealed and stored until use. A medical cotton ball is fixedly connected to one end of the hollow tube for final absorption and application of the paraffin oil. In one operation method of this application, the user can operate it with one hand, pressing the side of the sealing assembly from the opening side toward the support side with the thumb, while the remaining fingers can be used to secure the cotton swab. The thumb then applies external force away from the opening side, causing the sealing assembly to deform and generate stress, and then moving it away from the hollow tube. After the interior of the hollow tube is connected to the air, the paraffin oil is released to the cotton ball for use. The advantages of this structure are that it provides additional prestressing to enhance the sealing performance of the sealing assembly. After the external force is removed, the seal quickly resets and responds. The operation is simple and can be opened with one hand even when wearing gloves under sterile operating conditions. The pre-bent portion can rebound and reset after the external force is released, so that the structure has a preliminary self-sealing ability to prevent the leakage of residual paraffin. Therefore, the dosage of large-capacity paraffin oil disinfection cotton swabs can be adjusted through repeated operations.

[0040] As a preferred embodiment, the pre-bent portion 4 is provided along the axial direction of the hollow tube 1 and is pre-bent toward the opening side 33 .

[0041] As a preferred embodiment, the pre-bent portion 4 is arranged along the axial direction and radial direction of the hollow tube 1, so that the sealing component 3 can further increase the external force required to open the sealing component 3 under the action of double prestress, increase the sealing performance, and reduce the probability of accidental separation of the sealing component 3; further increase the prestress when the sealing component 3 is reset, which is conducive to further improving the sealing ability when the external force is removed and resealed.

[0042] In a further embodiment, the sealing assembly 3 is configured to bend toward the opening side 33 to indicate the cotton swab's open position to the user, thereby improving the convenience of using the cotton swab. Preferably, the pre-bent portion 4 is configured to be pre-bent toward the opening side 33 opposite the support side 32, so that the open position and the support side 32 are positioned relative to each other along the radial direction of the hollow tube 1. The force arm formed by the open position and the support side 32 is maximized, which is beneficial for reducing the force applied during single-handed operation.

[0043] In some embodiments, the sealing assembly 3 is also configured to be pre-bent, with the curvature of the sealing assembly 3 matching the curvature of the pre-bent portion 4 disposed in the axial direction. In other embodiments, the pre-bent portion 4 disposed in the axial direction is further provided with an elastic sheet or elastic strip having a matching curvature and disposed on the outside of the sealing assembly 3, thereby further increasing the prestress of the sealing assembly 3, thereby facilitating the sealing assembly 3 of the cotton swab to maintain its sealing capability against the hollow tube 1 after multiple openings.

[0044] In order to further enhance the mechanical connection stability between the sealing component 3 and the hollow tube 1, a concave-convex interlocking structure 5 is provided on the contact surface between the sealing component 3 and the hollow tube 1, which increases the contact area between the sealing component 3 and the hollow tube 1 and is beneficial to improving the sealing effect. In a preferred embodiment, a groove portion is provided on the end face of the hollow tube 1, and a protrusion portion matching the groove portion is provided on the corresponding end face of the sealing component 3. The two cooperate to form an interlocking, thereby improving the anti-seismic and anti-falling ability of the sealing component 3 during transportation and storage, and ensuring that the liquid does not leak or seep out. In another embodiment, a protrusion portion is provided on the end face of the hollow tube 1, and a groove portion matching the protrusion portion is provided on the corresponding end face of the sealing component 3. The two cooperate to form an interlocking, and under the action of external force, the opening of the groove portion of the sealing component 3 is increased, thereby reducing the contact surface of the concave-convex interlocking mechanism and reducing the interlocking effect, which is beneficial to separating the sealing component 3 during use.

[0045] As a preferred embodiment, a cavity 6 is provided within the sealing assembly 3. This cavity 6 extends through the sealing plug 31 and communicates with the interior of the hollow tube 1. By squeezing the cavity 6, the paraffin oil is expelled, enabling quantitative regulation of the paraffin oil. Furthermore, because the sealing assembly 3 is configured to bend toward the opening 33, pressing the sealing assembly 3 from the open position can slightly squeeze the cavity 6. This allows for low-dose use of the paraffin oil without separating the sealing assembly 3 from the hollow tube 1.

[0046] In one embodiment, a hard movable sleeve is provided on the outer side of the sealing component 3 to protect the sealing component 3 and reduce the probability of leakage of paraffin oil due to accidental squeezing of the sealing component 3.

[0047] In one embodiment, the outer surface of the hollow tube 1 is provided with graduated lines to indicate the amount of paraffin oil dispensed, allowing the user to visualize the amount of oil through the graduated lines, making operation more controllable. In further embodiments, the graduated lines can be set according to commonly used measurement units, such as milliliters, or according to the amount of paraffin oil dispensed by squeezing the cavity 6.

[0048] In one embodiment of the present application, for example Figure 5As shown, a cotton swab assembly is further proposed, which is specifically configured as an independent cotton swab bag, which includes a disposable paraffin oil sterilized cotton swab of any of the above embodiments, and is used to improve the safety of aseptic use of cotton swabs during transportation and storage and reduce the risk of foreign matter contamination. The cotton swab bag is made of medical-grade composite materials, has good sealing and easy-to-tear properties, and a detachable connection part 7, such as an easy-tear line or a pressed crack, is provided on the side of the long side of the bag body close to the sealing component 3. The cotton ball 2 is arranged at the end of the cotton swab assembly away from the detachable connection part 7. The user can easily tear open the cotton swab bag from the detachable connection part 7 and start to take out the cotton swab from the sealing component 3, reducing the probability of touching the end of the cotton ball 2, reducing the risk of contamination, and ensuring the sterility of the cotton ball 2 before use.

[0049] A rough strip 8 is also provided on the inner wall of the bag body below and near the detachable connection 7. When the user removes the cotton swab, the cotton ball 2 naturally contacts and gently rubs against the rough strip 8, effectively scraping away any loose fibers or floating hairs that may be on the surface of the cotton ball 2. This design reduces the risk of foreign matter contaminating the device and improves the cleanliness of the device surface.

[0050] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the present invention are included in the scope of the claims of the present invention.
