Description

Technical Field

[0001] This invention relates to a medical device, specifically a sterilization device for medical Luer connectors. Background Technology

[0002] Vascular access devices are commonly used therapeutic devices, including intravenous catheters. Vascular access devices are divided into peripheral catheters and central venous catheters. Intravenous infusion therapy is a treatment method that injects various medications, including blood, into the bloodstream. To avoid the pain of repeated punctures, many critically ill patients and those requiring long-term infusions or chemotherapy often use indwelling intravenous needles, central venous catheters (CVCs), and PICCs for intravenous infusion. These catheters all have infusion connectors at the ends, and bacterial contamination of these connectors can directly lead to bacterial growth and proliferation in the blood vessels and catheter system. The standardized, non-overflowing connector invented by the German inventor Ruhr, commonly known as the Ruhr connector, is widely used in clinical practice.

[0003] Currently, cotton swabs are commonly used in clinical practice to disinfect medical Luer connectors. However, this often involves direct contact with the cotton swabs by hand, and the short disinfection time or inadequate disinfection can easily lead to bacterial growth and reproduction on the Luer connector. To address these issues, patent CN218552904U discloses a capsule-type disinfection cap for disinfecting infusion connectors. However, this disinfection cap aims to solve the problem of disinfectant storage, and the disinfection method for the Luer connector is immersion and contact disinfection. Furthermore, the disinfection is concentrated on the end face of the Luer connector, without providing a disinfection solution for the sides, thus failing to guarantee disinfection efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a separate sterilization device for medical Luer connectors. This sterilization device has a reasonable structure and can simulate the wiping action of a human hand, improving the sterilization efficiency and effectiveness of the Luer connector. To achieve the above objectives, this invention adopts the following technical solution:

[0005] The sterilization device for a split-type medical Luer connector includes a sterilization cartridge and a handheld body. The sterilization cartridge consists of an outer shell and a sterilization body. The lower end of the sterilization body has an opening for inserting the Luer connector, and the upper end is a rotating shaft. The outer shell is fitted outside the rotating shaft of the sterilization body, and sterilization cotton is fixed inside the opening at the lower end of the sterilization body. The handheld body includes an outer shell, a pressing component, and a rotor. The outer shell is fitted outside the rotating shaft of the rotor. The pressing component and the outer shell are fitted together by a sliding block structure that ensures that the two can only move vertically. The pressing component is located between the outer shell and the rotor. The inner cavity of the pressing component has a cam that engages with a sliding groove on the rotor. A return spring is installed above the rotor and between the pressing component and the outer shell. A detachable fixing structure is provided between the outer shell of the sterilization cartridge and the handheld body. The upper part of the rotating shaft of the sterilization body is a shaped surface, and the lower part of the rotor is a shaped surface that engages with the shaped surface.

[0006] The above-mentioned sterilization device for a split-type medical Luer connector has a vertical groove in the inner cavity of the opening at the lower end of the sterilization body. A sterilization brush or sterilization cotton is fixed in the vertical groove, and a sterilization brush or sterilization cotton is fixed on the upper side of the inner cavity of the opening.

[0007] The aforementioned sterilization device for a split-type medical Luer connector has a detachable fixing structure between the outer shell of the sterilization cartridge and the handheld body. This fixing structure includes a locking head protruding towards the axis at the lower part of the inner cavity of the handheld body shell, and a locking groove that mates with the locking head on the outer side of the upper end of the sterilization cartridge outer shell.

[0008] The aforementioned sterilization device for a split-type medical Luer connector has a hook on the outer shell of the handheld body.

[0009] In use, the present invention is fixedly connected by the handheld body and the outer sleeve of the disinfection bullet. The upper end of the disinfection body of the disinfection bullet is locked to the lower part of the rotor of the handheld body. The thumb abuts and presses the part to make it move up and down, thereby driving the rotor to rotate. Finally, the rotation of the rotor drives the rotation of the disinfection body, so that the disinfection body performs rotational dynamic disinfection on the upper end surface and outer side surface of the Luer connector, ensuring the efficiency and effect of disinfection.

Detailed Implementation

[0017] Referring to the attached drawings, the sterilization device for the split-type medical Luer connector includes a sterilization cartridge and a handheld body. The sterilization cartridge consists of an outer sleeve 50 and a sterilization body 60. The lower end of the sterilization body has an opening for inserting into the Luer connector. The upper end of the sterilization body is rotatably fitted with the outer sleeve. The inner cavity of the opening at the lower end of the sterilization body has a vertical groove 61, in which a sterilization brush or sterilization cotton is fixed. Radial grooves are also provided on the upper side of the inner cavity of the opening for fixing the sterilization brush or sterilization cotton. The handheld body includes an outer shell 30, a pressing element 10, and a rotor 40. The outer shell is sleeved on the outside of the rotor's rotating shaft. The pressing element and the outer shell are connected by a sliding groove 31 and a slider 12 structure that ensures that the two can only move vertically. The press component is assembled with a protruding limiting block 13 on the lower edge of the slider to prevent it from coming out of the outer shell. The press component is located between the outer shell and the rotor. The inner cavity of the press component is provided with a cam 11, which engages with a sliding groove 41 on the rotor. A return spring 22 is installed between the rotor and the inner cavity of the press component. The upper part of the rotating shaft of the disinfection body is a shaped surface 62, and the lower part of the rotor is a shaped surface 42 that engages with the shaped surface. The outer shell of the disinfection bullet and the handheld body are provided with a separable fixing structure. In this example, the fixing structure includes a locking head 44 protruding towards the axis on the lower part of the inner cavity of the handheld body outer shell, and a locking groove 52 that engages with the locking head on the outer side of the upper end of the disinfection bullet outer shell.

[0018] The disinfection heads are soaked in disinfectant and are usually placed in sealed disinfection bags. One disinfection head per sealed bag or multiple disinfection heads per sealed bag can be used to ensure that the disinfection heads remain sterile and moist for a certain period of time.

[0019] In use, align the slot of the sterilizing head outer shell with the locking head of the handheld body outer shell and rotate to lock them together, ensuring that they will not separate during subsequent operations. At this time, the irregular surface on the top of the sterilizing body of the sterilizing head and the irregular surface on the bottom of the rotor of the handheld body are engaged. In this embodiment, these two irregular surfaces adopt a male and female structure, with the rotor of the handheld body being male and the irregular surface of the sterilizing head being female. Insert the handheld rotor into the irregular surface of the sterilizing body to achieve the locking engagement between the two. After the sterilizing head and the handheld body are connected, hold the handheld body and press it up and down with your thumb to make the pressing part move up and down. Since the pressing part and the outer shell are engaged through a vertical sliding rail structure, the pressing part can only move up and down and cannot rotate. The cam in the inner cavity of the pressing part engages with the sliding groove of the rotor, causing the rotor to rotate along the track of the sliding groove. The rotation of the rotor drives the rotation of the sterilizing body, thereby allowing the sterilizing body to disinfect the top and outer surfaces of the Luer connector inserted into its inner cavity through a sterilizing brush or sterilizing cotton soaked in disinfectant.

[0020] This invention provides a more thorough active disinfection method. By setting the rotor's slide rail, a standard number of rotations of the disinfection body can be set, thereby establishing operational guidelines. After pressing a certain number of times, the Luer connector can be disinfected, making the disinfection operation standardized and regulated. A counter can even be set based on the number of rotations to remind medical staff whether the prescribed number of presses has been reached.

[0021] During disinfection, medical staff can hold the Luer connector with their left hand and the disinfection device with their right hand, making it easy to operate.

[0022] Meanwhile, the hook 70 allows the handheld device to be inserted into the pocket of medical staff like a pen. This invention enables the handheld device to become a daily medical accessory that can be reused, reducing the cost of sterilization.
