Description

Technical Field

[0001] This utility model relates to the field of blood collection needle production technology, and in particular to a sterilization device for blood collection needle production. Background Technology

[0002] A blood collection needle is an instrument used to collect blood samples during medical testing. Blood collection needles need to be disinfected and sterilized before use to ensure their sterility, thereby guaranteeing the safety and effectiveness of medical use.

[0003] Currently, blood collection needles are typically sterilized using ethylene oxide during the production process. Ethylene oxide is a toxic gas, and current sterilization equipment usually does not have a leak-proof structure. If the sterilization equipment leaks, it will threaten the safety of the operators and have an impact on the environment.

[0004] Therefore, in the current production process of blood collection needles, ethylene oxide is commonly used for sterilization. However, ethylene oxide is a toxic gas, and current sterilization equipment typically lacks leak-proof structures. If a leak occurs, it will threaten the safety of operators and impact the environment. A new sterilization device for blood collection needle production could be designed. By adding a leak-proof structure to the sterilization device's cabinet door, a double safety measure would be implemented. If a leak occurs, the leaked gas would be confined to a small area and an alarm would be triggered, reducing the harm caused by the leak and alerting staff to handle the situation promptly. Utility Model Content

[0005] To address the current problem that blood collection needles are typically sterilized using ethylene oxide during production, which is a toxic gas, and that current sterilization equipment usually lacks leak-proof structures, a leak could threaten the safety of operators and cause environmental impact.

[0006] The technical solution of this utility model is as follows: a sterilization device for the production of blood collection needles, comprising a cabinet, a conveying component, and a holding component.

[0007] Preferably, a cabinet door is installed to shield the interior of the cabinet during operation and facilitate the placement and removal of blood collection needles, forming the first line of protection against ethylene oxide gas leakage. A protective enclosure, combined with a sealing door, encloses and seals the outside of the cabinet door, providing a second line of protection to limit the leaked gas in case of leakage. A detector (model VY027-CJ-530) monitors the ethylene oxide inside the protective enclosure and issues an alarm in case of leakage, alerting relevant personnel. An external extraction port can be connected to extract ethylene oxide between the protective enclosures in case of leakage, facilitating gas treatment. A first valve controls the extraction port. A delivery assembly is installed to sterilize the ethylene oxide gas delivered inside the cabinet. A holding assembly is installed to hold the blood collection needles.

[0008] Preferably, a shelf is fixedly installed on one side of the cabinet, and a movable door is provided on one side of the shelf, which is rotatably connected to the shelf.

[0009] Preferably, the conveying assembly includes an air tank and a connecting hose. The air tank is positioned above the placement rack, and a connecting hose is provided on one side of the air tank, with the connecting hose being connected to the air tank in a continuous manner.

[0013] As a preferred option, four sets of casters are fixedly installed at the bottom of the cabinet, and a set of handles is fixedly installed on both sides of the cabinet.

[0014] The beneficial effects of this utility model are:

[0015] 1. Compared to current blood collection needles, which are typically sterilized using ethylene oxide during production, ethylene oxide is a toxic gas. Current sterilization equipment usually lacks leak-proof structures. If a leak occurs, it will threaten the safety of operators and impact the environment. Our solution uses a cabinet door to shield the interior during operation, forming the first line of protection. A protective enclosure, combined with a sealing door, further encloses and seals the outside of the cabinet door, providing a second line of protection in case of a leak. This prevents ethylene oxide from leaking from the cabinet door and impacting the surrounding environment and personnel. A detector can promptly issue an alarm in case of a leak, allowing staff to easily remove the ethylene oxide through the extraction port. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5This utility model provides an embodiment of a sterilization device for the production of blood collection needles, comprising a cabinet 1, a conveying component, and a holding component. A cabinet door 101 is provided on one side of the cabinet 1, rotatably connected to the cabinet 1. A protective barrier 102 is fixedly installed around the cabinet 1, located outside the cabinet door 101. A sealing door 103 is provided on one side of the protective barrier 102, rotatably connected to the protective barrier 102. A detector 104 is fixedly installed inside the protective barrier 102. An exhaust port 106 is provided on one side of the protective barrier 102, communicating with the protective barrier 102 through a first valve 105. The conveying component is located on one side of the cabinet 1, and the holding component is located inside the cabinet 1. By providing the cabinet door 101, the interior of the cabinet 1 is shielded during operation, and the blood collection needles are easily retrieved and placed, forming the first line of defense. To prevent ethylene oxide gas leakage, a protective enclosure 102, in conjunction with a sealing door 103, surrounds and seals the exterior of the cabinet door 101. This provides a second layer of protection, limiting the leakage of gas in the event of a leak at the cabinet door 101. A detector 104 (model VY027-CJ-530) monitors the ethylene oxide inside the protective enclosure 102 and issues an alarm in case of a leak, alerting relevant personnel. An extraction port 106 connects to an external extraction device to extract the ethylene oxide between the protective enclosures 102 in case of a leak, facilitating gas treatment. A first valve 105 controls the extraction port 106. A conveying assembly delivers ethylene oxide gas into the cabinet 1 for sterilization. A holding assembly holds the blood collection needles.

[0024] Please see Figures 1-3In this embodiment, a placement rack 201 is fixedly installed on one side of the cabinet 1, and a movable door 202 is provided on one side of the placement rack 201, which is rotatably connected to the placement rack 201. The conveying assembly includes a gas storage tank 301 and a connecting hose 302. The gas storage tank 301 is located above the placement rack 201, and a connecting hose 302 is provided on one side of the gas storage tank 301, which is connected to the gas storage tank 301. The placement rack 201 is used to store the gas storage tank 301, and the movable door 202 is used to protect the gas storage tank 301 placed on the placement rack 201, while also facilitating the replacement of the gas storage tank 301. The gas storage tank 301 stores ethylene oxide gas, which is then conveyed into the cabinet 1 through the connecting hose 302. An installation box 401 is fixedly installed below the top surface inside the cabinet 1, and a conveying device is provided on one side of the installation box 401. The delivery pipe 402 is connected to the installation box 401. The delivery pipe 402 passes through the cabinet 1 and is connected to the connecting hose 302. Two sets of fans 403 are fixedly installed at the bottom of the installation box 401. By setting up the installation box 401 to install the fans 403, and by setting up the delivery pipe 402 to connect the connecting hose 302, ethylene oxide gas is delivered into the installation box 401 and blown into the cabinet 1 by the fans 403, so that the ethylene oxide gas is evenly distributed inside the cabinet 1. An exhaust pipe 602 is set on one side of the cabinet 1. The exhaust pipe 602 is connected to the cabinet 1 through a second valve 601. The exhaust pipe 602 can be connected to external exhaust gas treatment equipment to discharge the ethylene oxide inside the cabinet 1 after disinfection. The exhaust pipe 602 is controlled by the second valve 601.

[0025] Please see Figures 4-5In this embodiment, the holding component includes a slide rail 501, a support frame 502, positioning rods 503, a tray 504, and through holes 505. The slide rail 501 is fixedly installed on the side wall inside the cabinet 1. The support frame 502 is disposed inside the cabinet 1 and is slidably connected to the cabinet 1 via the slide rail 501. Multiple sets of positioning rods 503 are fixedly installed on the top of the support frame 502. Multiple sets of trays 504 are disposed inside the support frame 502. The trays 504 are engaged with the support frame 502 via the positioning rods 503. Multiple sets of through holes 505 are provided at the bottom of the trays 504. The tray 504 is supported by a support frame 502. The tray 504 can be positioned and installed inside the support frame 502 by a positioning rod 503. The support frame 502 can be pulled out of the cabinet 1 by a slide rail 501 to facilitate the loading and unloading of the tray 504. The through hole 505 allows gas to pass through, which facilitates the even distribution of ethylene oxide gas inside the cabinet 1. Four sets of casters 701 are fixedly installed at the bottom of the cabinet 1, and a set of handles 702 are fixedly installed on both sides of the cabinet 1. The handles 702 facilitate the movement of the cabinet 1 along the casters 701.

[0026] When working, the support frame 502 can be pulled out of the cabinet 1 using the slide rail 501 to facilitate the removal of the tray 504. The blood collection needle is laid flat inside the tray 504, and the tray 504 is placed back into the support frame 502 and positioned and fixed using the positioning rod 503.

[0027] During disinfection, the ethylene oxide gas inside the gas storage tank 301 is transported to the installation box 401 using the connecting hose 302 and the delivery pipe 402, and then blown to the tray 504 below using the fan 403. The gas can pass through the tray 504 through the through hole 505, so that the ethylene oxide gas can be evenly distributed inside the cabinet 1 to ensure the disinfection and sterilization effect. After the sterilization and disinfection work is completed, the exhaust pipe 602 is connected to the external exhaust gas treatment equipment, and the second valve 601 is opened to extract the ethylene oxide gas inside the cabinet 1.

[0028] The cabinet door 101 is used to seal and shield the inside of the cabinet 1 to prevent the leakage of ethylene oxide inside the cabinet 1, forming the first line of protection. If the cabinet door 101 leaks, the protective enclosure 102 and the sealing door 103 are used to enclose and seal the outside of the cabinet door 101, providing the second line of protection, confining the leaked gas inside the protective enclosure 102, and preventing the gas from spreading and harming the surrounding personnel and environment.

[0029] The detector 104 can detect ethylene oxide leaks in a timely manner and issue an alarm to remind relevant personnel to take action. The extraction port 106 can be used to connect an external extraction device to open the first valve 105, which can extract the leaked gas from the protective enclosure 102 for treatment.

[0030] Through the above steps, the cabinet door 101 shields the interior of the cabinet 1 during operation, forming the first line of protection. The protective barrier 102, in conjunction with the sealing door 103, encloses and seals the exterior of the cabinet door 101, providing a second line of protection in case of leakage at the cabinet door 101, preventing ethylene oxide from leaking from the cabinet door 101 and affecting the surrounding environment and personnel. The detector 104 can issue an alarm in time when a leak occurs, allowing staff to extract the ethylene oxide through the extraction port 106 for treatment. This addresses the problem that currently, blood collection needles are typically sterilized using ethylene oxide during production. Ethylene oxide is a toxic gas, and current sterilization devices usually do not have leak-proof structures. If the sterilization device leaks, it will threaten the safety of operators and have an impact on the environment.
