Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically, a rewarming injection tray. Background Technology

[0002] According to the Chinese Pharmacopoeia (2020 edition), room temperature storage of medicines refers to storing and keeping medicines at 10-30℃, while refrigerated storage refers to storing and keeping medicines at 2-10℃. Refrigerated storage can maintain the stability of drug efficacy and reduce degradation, denaturation, and inactivation of injection solutions at room temperature. Some active ingredients of drugs are heat-sensitive and must be refrigerated to prevent decomposition (such as certain antibiotics and immunomodulators). For refrigerated drugs, avoid immediate use after removal from the refrigerator. They usually need to be rewarmed for 20-30 minutes before injection to reduce local irritation and pain during injection of cold solutions and to prevent vasoconstriction from affecting absorption. Some drug solutions become more viscous at low temperatures; immediate injection without rewarming will prolong the injection time. Literature also reports that injection without rewarming is a risk factor for false positives and adverse reactions. A paper published in April 2025 showed that failure to rewarm, lack of rest after vaccination, and long-term medication use are risk factors for adverse reactions after vaccination with rotavirus live attenuated vaccine. A paper published in May 2021 showed that the rewarming time of tetanus antitoxin skin test solution has a significant impact on the positive rate of skin test results. The longer the rewarming time, the closer the temperature is to the human body surface temperature, and the lower the positive rate of skin test results.

[0003] Medical injection trays are used to hold ampoules, sterilization materials, syringes, and other instruments. Injectable medications are often placed directly into the tray after being taken from the refrigerator without being rewarmed, leading to insufficient rewarming time or no rewarming of refrigerated drugs. Possible reasons for this include: the lack of a dedicated rewarming area or labeling; the practice of placing refrigerated medications directly into the tray with room-temperature medications; nurses not distinguishing which medications require rewarming and preparing them for injection in sequence; the use of ordinary plastic / stainless steel trays without labels, leading users to rely on experience and potentially missing rewarming options; and the medications being placed in a room-temperature tray, but still below the recommended temperature, mistakenly believed to be at the appropriate level. Furthermore, the practice of placing refrigerated medications directly into the tray with room-temperature medications and not distinguishing which medications require rewarming before injection is repeated. Summary of the Invention

[0004] The purpose of this invention is to provide a rewarming injection tray to reduce the occurrence of refrigerated drugs not being rewarmed or having insufficient rewarming time.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] The rewarming injection tray includes a tray body, on which a rewarming timing device is provided.

[0007] In the rewarming injection tray described above, the tray body preferably includes a limiting plate, on which an ampoule hole and a timing device hole are provided. The rewarming timing device is disposed in the timing device hole, and the rewarming timing device is connected to the tray body and the limiting plate in a fixed connection or a non-fixed connection.

[0008] In the rewarming injection tray described above, the rewarming timing device is preferably a mechanical timer, which includes a spring-powered timer, an escapement timer, or a pendulum timer.

[0009] In the rewarming injection tray described above, the ampoule openings are preferably divided into room temperature ampoule openings and refrigerated ampoule openings, which are located in two separate areas on the left and right sides of the limiting plate.

[0010] In the rewarming injection tray described above, the ampoule openings are preferably divided into room temperature ampoule openings and refrigerated ampoule openings, with a rewarming reminder module located near each refrigerated ampoule opening; the rewarming injection tray also includes:

[0011] The detection module is a pressure sensor, which is used to detect the pressure received and convert the received pressure into an electrical signal.

[0012] The control module is electrically connected to the detection module and receives pressure-related electrical signals transmitted by the detection module. The control module includes a controller and a timer. The controller stores the injection solution rewarming time and an alert signal. The controller is set to start the timer when it receives an electrical signal representing a pressure change detected by the detection module, and to send an alert signal when the timer expires or exceeds the preset injection solution rewarming time.

[0013] The reheating reminder module is electrically connected to the control module, receives reminder signals sent by the controller, and completes the reheating reminder based on the reminder signals.

[0014] In the rewarming injection tray described above, the preferred rewarming reminder module is an indicator light, a buzzer, or a vibrator.

[0015] In the rewarming injection tray described above, a sterilization bucket hole is further provided on the limiting plate. A sterilization bucket is provided in the sterilization bucket hole. The sterilization bucket is divided into a tweezer bucket and an alcohol swab bucket. The lid of the tweezer bucket has a notch, while the lid of the alcohol swab bucket does not have a notch.

[0016] The rewarming injection tray described above also includes a partition plate for isolating the syringe receiving space.

[0017] In the rewarming injection tray described above, a slot is further provided on the inner surface of the tray body, and the partition plate is detachably connected to the tray body through the slot.

[0018] In the rewarming injection tray as described above, a limiting member is further provided on the inner surface of the tray body at a position corresponding to the limiting plate, and the limiting member is provided with a slot that restricts the up and down movement of the limiting plate.

[0019] This invention relates to a simple rewarming injection tray. The tray serves not only as a transport tool for injection-related devices but also as a timing tool for the rewarming of injection solutions. Refrigerated injection solutions placed in the tray undergo rewarming confirmation before proceeding to the next step, thus mitigating the problem of refrigerated drugs not being rewarmed or having insufficient rewarming time. It can quickly distinguish between room temperature and refrigerated injection solutions, automatically timing the rewarming after adding refrigerated solutions and providing a timing reminder for each refrigerated injection solution. This solves the problems of mixing room temperature and refrigerated injection solutions and the inability to individually time the rewarming of each refrigerated injection solution.

[0026] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the description of the present invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0033] This invention provides a rewarming injection tray equipped with a rewarming timer. After the doctor removes the medication from the refrigerator and places it in the tray, the timer starts recording the time. When the timer reaches the set rewarming time, it alerts the doctor that the medication has completed rewarming and is ready for injection. This timer on the rewarming injection tray effectively prevents refrigerated medications from being under-warmed or under-warmed.

[0034] Example 1

[0035] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a rewarming injection tray includes:

[0036] The tray body has a space within it to accommodate injection-related devices. These devices include ampoules, sterilization materials, syringes, or other commonly used injection-related devices such as vials and infusion bottles. The shape of the tray body is not particularly limited; it can be rectangular or square. The length of the tray body is 200-280 mm, the width is 120-200 mm, and the height is 30-80 mm; preferably, the length is 240 mm, the width is 160 mm, and the height is 50 mm. Specifically, the tray body includes four side panels (front, rear, left, and right) and a bottom plate connected to the side panels, forming the accommodating space. This space protects the injection-related devices, preventing them from falling out of the tray during movement. Furthermore, the tray body may be equipped with a matching lid, which covers the tray during the rewarming process, preventing the medication from being exposed.

[0037] like Figure 1 , Figure 2 and Figure 3As shown, the rewarming injection tray also includes: a limiting plate disposed within the tray body, the limiting plate having an ampoule hole, a sterilization container hole, and a timing device hole. The sterilization container hole contains a sterilization container, which is divided into a tweezers container and an alcohol swab container. The tweezers container's lid has a notch, facilitating the insertion of tweezers, hemostats, and other instruments into the tweezers container through the notch. The alcohol swab container's lid does not have a notch, ensuring good sealing, and can be used to hold alcohol swabs, etc. The timing device hole contains a timing device, which is a mechanical timer, including a spring-powered timer (wind-up timer), an escapement timer, or a pendulum timer. A spring-powered timer is preferred as the timing device. Spring-powered timers store energy using a helical spring and gradually release energy through gears, offering advantages such as small size and easy operation. The countdown time for rewarming the injection solution can be quickly set manually, and a mechanical bell alerts the user to the next step upon the end of the countdown. In this embodiment, the connection between the disinfection bucket, the timing device, the tray body, and the limiting plate can be a fixed connection or a non-fixed connection, preferably a non-fixed connection, whereby the disinfection bucket and the timing device are inserted into the corresponding holes of the limiting plate. A non-fixed connection allows for easy removal of the disinfection bucket and the timing device from the tray for cleaning and disinfection. In this embodiment, the thickness of the limiting plate is 0.01-30mm, preferably 10mm. The limiting plate is positioned near the upper surface of the tray body, parallel or substantially parallel to the bottom plate of the tray body, and occupies 1 / 2-1 / 3 of the total area of ​​the tray body's accommodating space. In this embodiment, the number of ampoule holes, disinfection bucket holes, and timing device holes is not particularly limited and can be set according to clinical operation requirements or habits. For example, the number of ampoule holes could be 5, the number of disinfection bucket holes 2, and the number of timing device holes 1. Furthermore, those skilled in the art can also set different numbers of holes according to the principles of this invention and usage needs. The limiting plate is used to create an area for placing ampoules, sterilization containers, and timing devices.

[0038] like Figure 1 , Figure 2 and Figure 3 As shown, the rewarming injection tray also includes a partition plate for isolating the syringe receiving space. The partition plate separates the syringes from other injection-related devices, ensuring that the items in the tray are neatly arranged and easily accessible. The partition plate is set to be perpendicular or substantially perpendicular to the bottom plate of the tray body. One end face of the partition plate is fixedly or movably connected to a limiting plate. The thickness of the partition plate is 0.01-30mm, preferably 10mm.

[0039] The partition plate is connected to the pallet body in either a fixed or movable manner. When fixed, the end face of the partition plate is fixed to the inner surface of the pallet body. When movable, such as... Figure 4As shown, slots are provided on the inner surface of the tray body at positions corresponding to the divider, allowing the divider to be detachably connected to the tray body via these slots. In one specific embodiment, the divider is movably connected to the tray body; this detachable divider design allows for easy removal of the divider from the tray body for cleaning and disinfection of the tray's interior.

[0040] The connection between the limiting plate and the pallet body can be either a fixed connection or a movable connection. When it is a fixed connection, the end face of the limiting plate is fixed to the inner surface of the pallet body or the end face of the partition plate. When it is a movable connection, such as... Figure 4 As shown, a limiting component is provided on the inner surface of the pallet body at a position corresponding to the limiting plate. The limiting component contains a slot that restricts the vertical movement of the limiting plate. The limiting plate is detachably connected to the pallet body via the limiting component. Preferably, the contact position between the limiting plate and the partition plate is movable, which can be achieved through magnetic connection or hinge. When magnetic connection is used, materials with opposite magnetic properties are provided at the contact positions of the limiting plate and the partition plate. Due to the limiting component, the limiting plate can be easily removed from the pallet body for cleaning and disinfection of the pallet interior.

[0041] like Figure 1-2 As shown, in another embodiment of the present invention, the outer edge of the upper end face of the tray body is provided with a rolled edge, the rolled edge surface is smooth and is treated by polishing process to avoid the edge from pricking the skin of the hand during use.

[0042] The rewarming injection tray provided in this embodiment has a simple structure. The tray not only serves as a loading and transportation tool for injection-related devices, but also as a timing tool for the rewarming of injection solutions. The refrigerated injection solutions loaded into the tray are rewarmed and confirmed before proceeding to the next step, which to some extent avoids the problem of refrigerated drugs not being rewarmed or having insufficient rewarming time.

[0043] Example 2

[0044] To address the difficulty in distinguishing between room-temperature and refrigerated injection solutions when stored together, this embodiment provides an alternative rewarming injection tray, the specific structure of which is as follows:

[0045] like Figure 5 As shown, the rewarming injection tray includes a tray body, the structure of which is the same as in Example 1, and will not be described again here.

[0046] The rewarming injection tray also includes a limiting plate disposed within the tray body, the limiting plate having ampoule holes, the ampoule holes being divided into room temperature ampoule holes and refrigerated ampoule holes, the room temperature ampoule holes being separate channels, and a rewarming reminder module being disposed near each refrigerated ampoule hole. The rewarming reminder module can be an indicator light, a buzzer, or a vibrator, preferably an indicator light. Using an indicator light as the rewarming reminder module allows for individual identification of whether the injection solution in the corresponding refrigerated ampoule hole has reached the set rewarming time based on the indicator light status. There is no special limitation on the number of room temperature and refrigerated ampoule holes, which can be set according to clinical operation requirements or habits, for example, 1-10 room temperature ampoule holes and 1-10 refrigerated ampoule holes. Furthermore, those skilled in the art can also set different numbers of ampoule hole positions according to the principle of this utility model and usage needs. The ambient temperature ampoule opening and the refrigerated ampoule opening can be located in the same area of ​​the limiting plate, or they can be located in two separate areas on the left and right sides of the limiting plate (e.g., Figure 5 As shown). Preferably, as shown in the figure. Figure 5 The aforementioned separate setup allows doctors to quickly identify the placement of refrigerated and room-temperature injection solutions during use, without needing to individually identify each port.

[0047] The rewarming injection tray also includes a detection module located at the bottom of each refrigerated ampoule opening. This module detects whether an ampoule is placed in the corresponding opening. Specifically, the detection module is a pressure sensor, and the number of pressure sensors matches the number of refrigerated ampoule openings; that is, a pressure sensor is located at the bottom of each refrigerated ampoule opening. The pressure sensor detects the pressure it receives and converts the received pressure into an electrical signal. When no ampoule is placed in the refrigerated ampoule opening, the pressure on the corresponding pressure sensor is zero. When an ampoule is placed in the refrigerated ampoule opening, the pressure on the corresponding pressure sensor is equal to the weight of the ampoule and the injection solution.

[0048] The rewarming injection tray also includes a control module disposed inside or on the back of the limiting plate, or inside or on the inner surface of the tray body. The control module is electrically connected to the detection module and receives pressure-related electrical signals transmitted by the detection module. The control module includes a controller and a timer. The controller stores the injection solution rewarming time and an alert signal. The controller is configured to start the timer when it receives an electrical signal representing a pressure change detected by the detection module, and to send an alert signal when the timer expires or when the preset injection solution rewarming time is exceeded.

[0049] The rewarming reminder module is electrically connected to the control module, receiving reminder signals from the controller and reminding the doctor that rewarming is complete. When the rewarming reminder module is an indicator light, it illuminates to indicate that the injection solution has completed rewarming, based on the controller's reminder signal. Preferably, a red and green dual-color indicator light is used. If no reminder signal is received, the indicator light illuminates red, indicating that the corresponding injection solution has not reached the preset rewarming time; if a reminder signal is received, the indicator light illuminates green, indicating that the corresponding injection solution has reached the preset rewarming time, and the doctor can remove the injection solution for the next step. When the rewarming reminder module is a buzzer, it emits an audible signal based on the controller's reminder. If no reminder signal is received, the buzzer does not emit an audible signal, indicating that the corresponding injection solution has not reached the preset rewarming time; if a reminder signal is received, the buzzer emits an audible signal to remind the doctor that rewarming is complete. The audible signal can be a short beep or a preset voice reminder. When the rewarming reminder module is a vibrator, it emits a vibration signal based on the controller's reminder signal. When no reminder signal is received, the vibrator will not emit a vibration signal, indicating that the corresponding injection solution has not reached the preset rewarming time; when a reminder signal is received, the vibrator will emit a vibration signal to remind the user that the rewarming is complete.

[0050] The limiting plate is also equipped with ampoule holes, sterilization bucket holes, and a sterilization bucket. The sterilization bucket is divided into a tweezer bucket and an alcohol swab bucket. The tray body is also equipped with a divider plate. The structure of these components is the same as in Embodiment 1. In addition, a power module, a switch, and a charging module are provided inside the limiting plate, on the back, or inside or on the inner surface of the tray body. The power module supplies power to the whole system, and the charging module includes a universal charging port for charging the power supply. These are conventional settings in the art and will not be described in detail here.

[0051] The rewarming injection tray provided in this embodiment can not only quickly distinguish between room temperature injection solutions and refrigerated injection solutions, but also automatically complete the rewarming timer after placing the refrigerated injection solution in it, and provide a rewarming timer reminder for each refrigerated injection solution. This solves the problems of mixing room temperature injection solutions and refrigerated injection solutions and the inability to individually time the rewarming of each refrigerated injection solution.

[0052] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several improvements and additions without departing from the principle of the present utility model, and these improvements and additions should also be considered within the protection scope of the present utility model.
