Description

Technical Field

[0001] This application relates to the field of wiping and disinfection components, and more particularly to a component for simultaneous internal and external wall disinfection of a medical multi-port connector. Background Technology

[0002] In the medical industry, multi-port connectors (with at least three ports) are widely used in various scenarios due to their flexible control over fluid flow and ability to connect multiple pathways. For example, during intravenous infusion, the multiple ports of a multi-port connector can be connected to different fluid pathways such as normal saline, adrenaline, antibiotics, and nutritional solutions; during blood transfusion, the multiple ports can be connected to different fluid pathways such as red blood cell suspension, plasma / platelet, normal saline, and anticoagulants. Multi-port connectors integrate multiple pathways and allow for flow direction adjustment by rotating the handle, enabling separate access to each port and reducing the risk of repeated punctures.

[0003] As a component that frequently comes into contact with various liquids and pipeline interfaces, multi-port connectors require sterilization during use, especially in situations where rapid sterilization is needed and there is no obvious organic residue. For example, during intravenous infusion, before each connection to the infusion line, syringe, extension tube, or transducer, the inner surface of the port should be wiped with a cotton swab or cotton stick, followed by wiping the outer surface of the port with an alcohol swab to achieve internal and external sterilization.

[0004] In practical applications, in high-intensity nursing environments that require rapid sterilization, medical staff need to switch back and forth between cotton pads and cotton swabs for cleaning, which results in many steps and low cleaning efficiency. Utility Model Content

[0005] In view of this, the purpose of this application is to provide a device for simultaneous disinfection of the inner and outer walls of a medical multi-port connector, in order to solve the problem of low disinfection efficiency in existing disinfection methods for multi-port connectors.

[0006] To achieve the above technical objectives, this application provides a component for simultaneous disinfection of the inner and outer walls of a medical multi-port connector, comprising: a cleaning rod and a cleaning cloth;

[0007] The front end of the cleaning stick is provided with a cotton pad;

[0008] The cotton block can be inserted into the opening of the multi-port interface;

[0009] The cleaning cloth is disposed at the front end of the cleaning rod and surrounds the outer periphery of the cotton block;

[0010] When the cotton block is inserted into the opening, the cleaning cloth can cover the outer wall of the opening.

[0011] Furthermore, the cleaning cloth is formed into a funnel shape.

[0012] Furthermore, it also includes: packaging bags;

[0013] The packaging bag is used to hold the cleaning stick and the cleaning cloth;

[0014] When the cleaning cloth is placed into the packaging bag, the cleaning cloth is in a flattened state.

[0015] Furthermore, the front end of the packaging bag is provided with an easy-open structure, so that the front end of the packaging bag can be opened;

[0016] When the cleaning cloth is placed into the packaging bag, it is located at the front end of the packaging bag.

[0017] Furthermore, the packaging bag includes two films;

[0018] The two membranes are aligned and their edges are joined to form a bag-like structure.

[0019] Furthermore, the front end of the diaphragm is provided with a force-bearing portion;

[0020] The two force-bearing parts constitute the easy-opening structure;

[0021] The force-applying part is used by the user to apply force to separate the front ends of the two diaphragms, thereby opening the packaging bag.

[0022] Furthermore, the diaphragm is a paper-plastic composite sheet.

[0023] Furthermore, the diameter of the cotton block is greater than or equal to 7 mm.

[0024] Furthermore, the cleaning cloth is a cotton cloth made of non-woven fabric.

[0025] Furthermore, the cleaning rod is a flexible rod.

[0026] As can be seen from the above technical solutions, this application provides a component for simultaneous disinfection of the inner and outer walls of a medical multi-port connector, comprising: a cleaning rod and a cleaning cloth; a cotton block is provided at the front end of the cleaning rod; the cotton block can extend into the opening of the multi-port connector; the cleaning cloth is provided at the front end of the cleaning rod and surrounds the outer periphery of the cotton block; when the cotton block extends into the opening, the cleaning cloth can cover the outer wall of the opening.

[0027] When in use, medical staff can soak cotton balls and cleaning cloths in alcohol, insert the cotton balls into the opening to wipe the inner wall of the opening, and at the same time clean the outer wall of the opening with the cleaning cloth. This achieves simultaneous disinfection and wiping of the inner and outer walls of the opening, thereby reducing the number of operation steps and improving cleaning efficiency. It effectively solves the problem of low disinfection efficiency of existing disinfection methods for multi-port connectors. Attached Figure Description

For example, they can refer to a fixed connection, a replaceable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0036] Please see Figure 1 This application provides a synchronous disinfection component for the inner and outer walls of a medical multi-port connector (hereinafter referred to as the disinfection component); the disinfection component includes: a cleaning rod 10 and a cleaning cloth 20.

[0037] In this embodiment, the cleaning stick 10 has a stick-shaped structure that allows the user to hold it. A cotton pad 11 is provided at the front end of the cleaning stick 10. A cleaning cloth 20 is disposed at the front end of the cleaning stick 10 and surrounds the outer periphery of the cotton pad 11. For ease of explanation, this embodiment uses... Figure 1 The left end of the center view is the front end; in practical applications, one end of the cleaning rod 10 can be taken as the front end, and the other end as the rear end.

[0038] In practical applications, the disinfection components provided in this embodiment are applicable to the same scenarios as those for wiping and disinfecting multi-port connectors upon entry into the field, such as port disinfection before intravenous access connection, port disinfection for blood transfusion or blood product access, and routine disinfection during catheter maintenance. When using, the cotton pad 11 and cleaning cloth 20 are soaked in alcohol to simultaneously wipe the inner and outer walls of the port. Wiping the port surface with alcohol for 15-30 seconds, allowing it to air dry, and then connecting it effectively kills bacteria and enveloped viruses, meeting the requirements of the INS Infusion Therapy Practice Standards and the WHO Guidelines for the Prevention of Catheter-Related Bloodstream Infections (CRBSI).

[0039] Correspondingly, in scenarios where alcohol cannot completely disinfect multi-port connectors due to residual organic matter such as blood, pus, or mucus, or where spore-forming microorganisms are present in the environment, users can adopt other disinfection methods based on the on-site assessment. Specifically, the disinfection device provided in this embodiment is applicable to the disinfection of multi-port connectors before connection, during maintenance, and when idle, and in practical applications, medical personnel can determine the applicability of this disinfection device based on existing technology and experience.

[0040] During the disinfection process, the user can soak cotton pad 11 and cleaning cloth 20 with an appropriate amount of disinfectant (such as alcohol), and then insert cotton pad 11 into the opening of the multi-port interface. Since the cleaning cloth 20 is wrapped around the outer periphery of cotton pad 11, when cotton pad 11 is inserted into the opening, the cleaning cloth 20 can cover the outer wall of the opening. At this time, the user holds the cleaning stick 10, gently rotates and pushes it repeatedly, which can drive cotton pad 11 to wipe the inner wall of the opening and drive cleaning cloth 20 to wipe the outer wall of the opening, thus achieving simultaneous wiping of the inner and outer walls of the opening.

[0041] As one method of use, after the cotton pad 11 is inserted into the opening of the multi-port connector, the user can also hold the cleaning cloth 20 with gloved fingers to increase the contact area and abutment force between the cleaning cloth 20 and the outer wall of the opening, thereby further improving the wiping effect. At the same time, during the wiping process, the cleaning cloth 20 can move the cotton pad 11 to achieve simultaneous disinfection of the inner and outer walls. It should be noted that, in this embodiment, the length of the part of the cleaning cloth 20 extending out of the cleaning rod 10 can be configured to be greater than the distance from the end of the opening to the middle of the multi-port connector, for example, greater than 20mm, to ensure that the cleaning cloth 20 can cover and wipe more areas of the outer wall of the opening.

[0042] Similarly, the length of the cotton block 11 is configured to meet the cleaning depth requirements of the opening; for example, if the distance from the end of the opening to the middle of the multi-port connector is 10mm, then the length of the cotton block 11 can be configured to be greater than 10mm.

[0043] In some scenarios, when the depth to which the inner wall of the opening needs to be cleaned exceeds the length of the cotton pad 11, the user can adjust the depth of the cotton pad 11 by holding the cleaning stick 10. If necessary, the cleaning cloth 20 can be folded and inserted into the opening to adapt to different cleaning depth requirements. Therefore, the disinfection component of this solution not only improves disinfection efficiency but also ensures thorough cleaning of the inner and outer walls of the opening.

[0044] Compared to the method of medical staff having to use cotton pads and swabs to wipe separately, using this disinfection kit can reduce disinfection steps and improve work efficiency.

[0045] In one embodiment, the cleaning cloth 20 is formed into a funnel shape, so that when the cotton block 11 is inserted into the opening, the cleaning cloth 20 can abut against the outer wall of the opening end to ensure cleaning effect.

[0046] In one implementation, the cleaning rod 10 can be a flexible rod with a certain degree of elasticity and deformability. Specifically, the cleaning rod 10 can be a thermoplastic elastic rod.

[0047] In one implementation method, the cleaning cloth 20 is a cotton cloth made of non-woven fabric, specifically, it can be composed of multiple layers of medical non-woven fabric stacked together to form a cotton cloth structure. It should be noted that medical non-woven fabrics (such as polypropylene spunbond non-woven fabric, spunlace non-woven fabric, etc.) can meet the standards of "Medical Absorbent Cotton" (YY / T 0330) and "Medical Dressings" (ISO13795) after sterilization processes such as irradiation and ethylene oxide, and have no risk of fiber shedding, avoiding foreign body residue in wounds, while also possessing absorbency and softness. Since medical non-woven fabric is currently the mainstream material for medical cotton pads, especially widely used in disinfection and wound care scenarios, the specific preparation process of the cleaning cloth 20 will not be described in detail in this embodiment.

[0048] In actual production, after the cleaning cloth 20 is prepared, it can be cut into a fan-shaped trapezoid. Then, the cleaning cloth 20 is tightly wrapped around the bottom of the cotton block 11, with the top naturally unfolding to form a trumpet shape. The fixing method between the cleaning cloth 20 and the cotton block 11, as well as the shaping method of the cleaning cloth 20 itself, can be achieved using medical adhesives. For example, after cutting the cleaning cloth 20, medical adhesive is applied to the edges that need to be bonded. Then, the cleaning cloth 20 is tightly adhered to the bottom of the cotton block 11 and wrapped around it in a trumpet shape, pressing the cleaning cloth 20 firmly. Specifically, it can be flattened to allow the edges of the cleaning cloth 20 to bond. The cleaning cloth 20 can then be unfolded for use. Alternatively, existing technologies such as ultrasonic welding and hot pressing can be used. Taking ultrasonic welding as an example, after the cleaning cloth 20 wraps around the cotton block 11, an ultrasonic welding head is used to rapidly vibrate along the bottom of the cotton block 11, causing the fibers of the two to fuse together. The same principle applies to the bonding area of ​​the cleaning cloth 20 itself; after the edges of the cleaning cloth 20 are overlapped, an ultrasonic welding head is used to rapidly vibrate along the overlap.

[0049] In a further improved embodiment, please refer to Figures 1 to 3 The disinfection component also includes: a packaging bag 30; the packaging bag 30 is used to hold the cleaning stick 10 and the cleaning cloth 20; the cloth 20 is stored and carried to ensure its sterility; when the cleaning cloth 20 is put into the packaging bag 30, the cleaning cloth 20 is in a flattened state.

[0050] The cleaning stick 10 and cleaning cloth 20, packaged in the packaging bag 30, are easy to carry and store, and ensure a sterile environment for the cleaning stick 10 and cleaning cloth 20. The packaging bag 30 is sealed with heat sealing technology to ensure airtightness.

[0051] In one embodiment, the front end of the packaging bag 30 is provided with an easy-open structure, so that the front end of the packaging bag 30 can be opened; when the cleaning cloth 20 is put into the packaging bag 30, it is located at the front end of the packaging bag 30.

[0052] The easy-open structure can be, for example, a pre-set tear line or tear label, allowing users to quickly open the packaging bag 30 without compromising the sterility of the items inside.

[0053] In a more specific embodiment, the packaging bag 30 includes two films 31; the two films 31 are aligned and their edges are fitted to form a bag-like structure.

[0054] The membrane 31 can be made of medical-grade composite membrane material, such as medical-grade paper-plastic composite sheet, which has good barrier properties to prevent microbial invasion. The outer periphery of the two membranes 31 can be sealed by heat sealing technology to ensure the airtightness and sterility of the packaging bag 30. Users can simply tear open the membrane 31 along the easy-open structure to remove the cleaning stick 10 and cleaning cloth 20.

[0055] In one embodiment, the front end of the diaphragm 31 is provided with a force-bearing part 32; the two force-bearing parts 32 form an easy-opening structure; the force-bearing part 32 is used for the user to exert force to separate the front ends of the two diaphragms 31 so that the packaging bag 30 can be opened.

[0056] In application, the force-bearing part 32 can be a protruding structure that protrudes from the main body of the diaphragm 31, or it can be an unencapsulated part located at the edge of the diaphragm 31, specifically so that the user can separate the two diaphragms 31 through the force-bearing part 32.

[0057] By providing a force-bearing portion 32 at the front end of the diaphragm 31, a contactless disinfection method can be provided for the disinfection items. Specifically, the force-bearing portion 32 can cause the front ends of the two diaphragms to separate, forming a shape similar to... Figure 3 The opening structure is shaped like a mask; then, the user can grip the cleaning stick 10 through the membrane 31 and cause the cleaning cloth 20 and cotton pad 11 to extend outside the packaging bag 30, so that the cleaning cloth 20 and cotton pad 11 are soaked in disinfectant and then come into contact with the outer and inner walls of the opening respectively; then, the user's fingers cover the outside of the membrane 31, so that the user can grip the cleaning cloth 20 covering the outer wall of the opening through the membrane 31, so as to achieve the disinfection operation of the cleaning cloth 20 and cotton pad 11 without direct contact with the cleaning cloth 20.

[0058] In this way, the sterility of the disinfection process can be guaranteed, and the risk of contamination caused by direct hand contact with the cleaning cloth 20 can be avoided, thereby effectively reducing the risk of multi-connector box catheter-related infection (CRBSI).

[0059] In one embodiment, the diameter of the cotton block 11 is greater than or equal to 7 mm. This diameter can meet the disinfection requirements of the common multi-port connector's port diameter and the wiping disinfection effect, thereby improving the adaptability of the disinfection component.

[0060] The above are merely preferred embodiments of this application and are not intended to limit the present invention. Although the present application has been described in detail with reference to examples, those skilled in the art can still modify the technical solutions described in the foregoing examples or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
