Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of vaccine inoculation warmers, specifically a vaccine inoculation warmer. Background Technology
[0002] Many biological products and vaccines now require low-temperature storage. If the temperature of the vaccine is too low when used, it may cause discomfort and increase stress, affecting its effectiveness. The effects may be more pronounced in winter. Therefore, vaccines need to be warmed up before use. Warming up mainly includes two methods: natural placement and warm water bath.
[0003] When warming the vaccine in a water bath, inserting the vaccine tube vertically or at a fixed angle into the water bath results in a significant temperature difference between the upper and lower layers of the vaccine due to the limited contact area between the vaccine tube and the warm water. This temperature difference can reach 5-8°C, especially when the vaccine tube is large, leading to uneven warming of the vaccine.
[0004] To address the problem of uneven vaccine warming, this application proposes a vaccine warmer. Utility Model Content
[0005] In view of the shortcomings of the existing technology, this utility model provides a warming device for vaccine administration.
[0006] To achieve the above objectives, the technical solution of this utility model is as follows:
[0007] A vaccine incubator includes: an incubator having a water bath chamber formed inside, the water bath chamber being filled with an aqueous solution;
[0008] The floating frame, which is installed inside the water bath chamber, includes:
[0009] The center of buoyancy is the part of the body that floats on the surface of an aqueous solution.
[0010] A float arm is mounted on the side wall of the buoyancy core and floats on the surface of the aqueous solution. The float arm has mounting holes that extend through it along the height direction of the buoyancy core.
[0011] The elastic element is located at the end of the float away from the center of buoyancy. When the elastic element collides with the inner wall of the recovery box, it generates a reaction force that causes the float to vibrate.
[0012] The paddle, whose rotation is mounted at the bottom of the buoyancy core, drives the buoyancy core to move on the surface of the water solution;
[0013] The driving source is located inside the buoyancy core, and the output end of the buoyancy core is fixedly coaxially with the paddle, driving the paddle to rotate and generating a force that propels the buoyancy core to move on the surface of the aqueous solution.
[0014] Preferably, the driving source is a motor, which is fixedly installed at the bottom of the buoyancy core. The output end of the motor is fixed at the center of the paddle. The angle between the central axis of the paddle and the height direction of the buoyancy core is 0-30°. When the paddle rotates, it pushes the buoyancy core to float on the surface of the aqueous solution.
[0015] Preferably, the end of the elastic element facing away from the float is arc-shaped, which reduces the friction between the elastic element and the recovery box and promotes the float to float on the surface of the aqueous solution.
[0016] Preferably, the inner diameter of the mounting hole is smaller than the outer diameter of the vaccine vial's port, and the float pushes the vaccine vial to move in the aqueous solution through the mounting hole.
[0017] Preferably, a controller is provided on the outer wall of the rewarming chamber, and a heater is provided at the bottom of the rewarming chamber. The heater is electrically connected to the control terminal of the controller, and the signal output terminal of the controller is electrically connected to the motor to control the speed of the motor.
[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0019] 1. This utility model uses a paddle that rotates under the drive of a power source to move the buoyancy center on the surface of the aqueous solution, so that the vaccine vial constantly changes position in the water bath, further ensuring the uniformity of the vaccine's heating and warming.
[0020] 2. This utility model utilizes a silicone elastic element that generates a suitable reaction force when it collides with the inner wall of the incubator, causing the float arm to vibrate, which in turn causes the vaccine vial to vibrate, resulting in more uniform heating and reheating of the vaccine.

[0028] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0029] Example
[0030] like Figures 1-5 As shown, a vaccine incubator includes: an incubation chamber 8, which has a water bath cavity inside, filled with an aqueous solution; the incubation chamber 8 can be made of food-grade stainless steel, and the capacity of its internal water bath cavity is set according to actual needs, for example, it can hold 5-10L of aqueous solution. The aqueous solution can be physiological saline, which meets hygiene standards and ensures good heat conductivity.
[0031] The float frame, installed within the water bath chamber, includes: a buoyancy core 5, which floats on the surface of the aqueous solution; and float arms 3, which are mounted on the side walls of the float arms 3 and also float on the surface of the aqueous solution. Mounting holes 7 are provided through the float arms 3 along the height direction of the buoyancy core 5. The buoyancy core 5 is made of lightweight and waterproof plastic and has a spherical structure, enabling it to float stably on the surface of the aqueous solution. The float arms 3 are also made of lightweight plastic, and 3-4 can be installed, evenly distributed on the side walls of the buoyancy core 5. The diameter of the mounting holes 7 on each float arm 3 can be determined according to the size of common vaccine vials 2.
[0032] The elastic element 1 is located at the end of the float arm 3 away from the buoyancy center 5. When the elastic element 1 collides with the inner wall of the warming box 8, it generates a reaction force that causes the float arm 3 to vibrate. The elastic element 1 is made of silicone and is fixed to the end of the float arm 3 away from the buoyancy center 5 by adhesive bonding. Its length can be set to 2-3cm.
[0033] The paddle 6 is rotatably mounted at the bottom of the buoyancy center 5, driving the buoyancy center 5 to move on the surface of the aqueous solution; the paddle 6 is made of corrosion-resistant plastic, is blade-shaped, and is rotatably mounted at the bottom of the buoyancy center 5 via bearings.
[0034] The drive source is located inside the buoyancy center 5. The output end of the buoyancy center 5 is coaxially fixed with the paddle 6, driving the paddle 6 to rotate and generating a force that pushes the buoyancy center 5 to move on the surface of the aqueous solution. The drive source can be a small DC motor, the output power of which is selected according to actual needs. It is fixedly installed inside the buoyancy center 5, and the output end is coaxially fixed with the paddle 6 through a coupling.
[0035] Specifically, the incubation chamber 8 is made of food-grade stainless steel, ensuring hygiene and safety during the incubation process and maintaining a good water bath temperature. The saline solution, as an aqueous solution, has high thermal conductivity, allowing the vaccine vials 2 to be heated evenly while preventing contamination. The lightweight plastic material of the buoyancy core 5 and float arms 3 ensures the overall structure floats stably on the water surface. Multiple float arms 3 can hold multiple vaccine vials 2 simultaneously, improving incubation efficiency. The elastic silicone element 1 generates a suitable reaction force when it collides with the inner wall of the incubation chamber 8, causing the float arms 3 to vibrate, which in turn causes the vaccine vials 2 to vibrate, resulting in more even heating. The paddle 6, driven by a power source, rotates, propelling the buoyancy core 5 across the aqueous solution surface, causing the vaccine vials 2 to continuously change position in the water bath, further ensuring uniform heating. A small DC motor, as the power source, has low energy consumption and appropriate driving force, stably driving the paddle 6 to rotate and ensuring the effective movement of the buoyancy core 5.
[0036] In one embodiment, the drive source is a motor 4, which is fixedly mounted at the bottom of the buoyancy core 5. The motor is powered by a rechargeable battery, which is removably installed inside the buoyancy core 5. The output end of the motor 4 is fixed at the center of the paddle 6. The angle between the central axis of the paddle 6 and the height direction of the buoyancy core 5 is 0-30°. When the paddle 6 rotates, it pushes the buoyancy core 5 to float on the surface of the water solution. The motor 4 is a miniature DC geared motor 4 with a power of 8W, which is fixedly mounted at the bottom of the buoyancy core 5 with screws. The output end of the motor 4 is fixed to the center of the paddle 6 by welding. The angle between the central axis of the paddle 6 and the height direction of the buoyancy core 5 is set to 15°.
[0037] Specifically, the miniature DC geared motor 4 is characterized by its small size and high torque, enabling it to stably drive the paddle 6 to rotate. It is securely fixed to the bottom of the buoyancy center 5, preventing loosening during its movement. The central axis of the paddle 6 forms a 15° angle with the height direction of the buoyancy center 5, allowing the paddle 6 to not only propel the buoyancy center 5 horizontally but also generate upward or downward forces during rotation. This further promotes the buoyancy center 5's buoyancy, enhances the agitation effect of the vaccine vial 2 in the aqueous solution, ensures more uniform vaccine rewarming, and improves the flexibility of the buoyancy center 5's movement.
[0038] In one embodiment, the end of the elastic element 1 facing away from the float 3 is arc-shaped to reduce the friction between the elastic element 1 and the warming box 8, and to promote the float 3 to float on the surface of the aqueous solution. The end of the elastic element 1 facing away from the float 3 is processed into an arc shape with a radius of 1cm and the arc surface is smooth and burr-free.
[0039] Specifically, the arc-shaped end greatly reduces the friction between the elastic element 1 and the warming chamber 8. When the float arm 3 drives the elastic element 1 to contact the inner wall of the warming chamber 8, it can slide or collide more smoothly, reducing the obstruction to the floating of the float arm 3 and making the float arm 3 float more flexibly on the surface of the aqueous solution. This ensures that the vaccine bottle 2 can move more freely in the water bath, improving the uniformity and efficiency of the warming process.
[0040] In one embodiment, the inner diameter of the mounting hole 7 is smaller than the outer diameter of the port of the vaccine vial 2. The float 3 propels the vaccine vial 2 through the mounting hole 7 to move it in the aqueous solution. The inner diameter of the mounting hole 7 is set to 1.2 cm, while the outer diameter of the port of a common vaccine vial 2 is 1.5 cm. The float 3 is made of a plastic material with a certain degree of toughness, so that when the vaccine vial 2 is placed in the mounting hole 7, the edge of the mounting hole 7 can make close contact with the port of the vaccine vial 2.
[0041] Specifically, the inner diameter of the mounting hole 7 is smaller than the outer diameter of the port of the vaccine vial 2, allowing the vaccine vial 2 to be stably placed within the mounting hole 7 without falling out. During movement and vibration, the float arm 3 can propel the vaccine vial 2 through the mounting hole 7, ensuring that the vaccine vial 2 moves with the float arm 3, further ensuring uniform heating of the vaccine vial 2, and preventing collision damage caused by the vaccine vial 2 floating randomly in the water bath.
[0042] In one embodiment, a controller 9 is installed on the outer wall of the rewarming chamber 8, and a heater is installed at the bottom of the rewarming chamber 8. The heater is electrically connected to the control terminal of the controller 9, and the signal output terminal of the controller 9 is electrically connected to the motor 4 to control the speed of the motor 4. The controller 9 is a single-chip microcomputer controller with a display screen, installed in the middle of the outer wall of the rewarming chamber 8 for easy observation and operation by the operator. The heater uses electric heating tubes, evenly distributed at the bottom of the rewarming chamber 8, and its power can be selected according to the capacity of the rewarming chamber 8, such as 500-1000W. The heater is connected to the control terminal of the controller 9 through wires, and the signal output terminal of the controller 9 is connected to the motor 4 wirelessly. The controller 9 is equipped with adjustment buttons to adjust the speed of the motor 4, such as setting 5 levels corresponding to different speeds.
[0043] Specifically, the microcontroller controller 9 with a display screen can intuitively display parameters such as water bath temperature and motor 4 speed, facilitating monitoring and adjustment by operators. The electric heating element, acting as a heater, provides uniform and efficient heating, quickly heating the aqueous solution to the required temperature and maintaining it at a constant temperature under the control of the controller 9. By controlling the speed of motor 4 through the controller 9, the moving speed of the float 5 can be adjusted according to the type of vaccine and the reheating requirements. When rapid reheating is needed, the motor 4 speed can be increased, allowing the vaccine vial 2 to move faster and be heated more evenly; when slow reheating is needed, the speed can be reduced to ensure the stability of the reheating process, further improving the applicability of the reheater.
[0044] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
