Description

Technical Field

[0001] This invention relates to the field of vaccine warming equipment technology, and in particular to a temperature-uniform vaccine warming device. Background Technology

[0002] Animal inactivated vaccines are typically stored in refrigerated cabinets to prevent spoilage. When vaccinating livestock, the vaccines must be removed from the refrigeration cabinet and then warmed to between 20°C and 25°C using a water bath or by hand. Inadequate or improper warming of the vaccine before injection can cause significant stress in livestock. While a water bath provides more even warming than hand handling, it is currently the most common method for vaccine warming. However, vaccines become inactive at high temperatures, meaning a high-temperature water bath cannot provide rapid warming; therefore, the warming process is lengthy. To save time on warming up, vaccines are typically placed in a water bath immediately after being removed from the refrigerator and then carried to the vaccination site for injection. However, during transport, the water bath solution shakes, causing some of it to splash onto the vaccine bottle opening. When the vaccine is drawn out with a syringe, the syringe first comes into contact with the water bath solution adhering to the vaccine bottle opening, easily contaminating the vaccine. In addition, vaccines that need to be warmed up are currently placed upright in the water bath. When the water bath is shaken, the water bath solution shakes, easily impacting the vaccine and causing it to tip over. Summary of the Invention

[0003] This invention provides a temperature-uniform vaccine warming device to overcome the disadvantage that the water bath solution easily splashes onto the vaccine bottle opening during the existing vaccine warming process using the water bath method, causing contamination of the vaccine.

[0004] The technical solution is as follows: A temperature-uniform vaccine warming device includes an outer shell, an electric heating wire disposed inside the outer shell, a sealing cap threaded to the upper side of the outer shell, a support plate slidably and sealingly connected inside the outer shell, the outer shell and the support plate cooperating to form a water bath chamber containing a water bath liquid, annularly distributed support rings ball-jointed on the support plate, symmetrically distributed connecting rods fixed to the lower side of the support rings, the symmetrically distributed connecting rods on the same support rings jointly limiting and slidably connecting to a squeezing plate, the squeezing plate sealingly cooperating with the adjacent support rings, a first squeezing cylinder fixedly connected to the adjacent squeezing plate on one side of the connecting rod sealingly and slidably connected, a squeezing element sealingly and slidably connected to the adjacent connecting rod inside the first squeezing cylinder, the squeezing element cooperating with the adjacent first squeezing cylinder to form a squeezing chamber containing gas, a spring fixedly connected between the side of the squeezing element away from the adjacent support ring and the adjacent connecting rod, an annular airbag fixedly connected inside the support ring, the annular airbag communicating with the adjacent squeezing chamber through a conduit.

[0005] Furthermore, a second extrusion cylinder is fixedly connected to the side of the connecting rod away from the adjacent support ring on the other side. The second extrusion cylinder is slidably and sealed to an adjusting member that is slidably and sealed to the adjacent connecting rod. The adjusting member and the adjacent second extrusion cylinder cooperate to form a power chamber, which contains hydraulic oil. A spring is fixedly connected between the adjusting member and the adjacent second extrusion cylinder. A third extrusion cylinder is fixedly connected to the outer shell. A piston rod is slidably and sealed to the third extrusion cylinder. The piston rod and the third extrusion cylinder cooperate to form a height adjusting chamber, which contains hydraulic oil. The power chamber is connected to the height adjusting chamber through a conduit.

[0006] Furthermore, the ratio of the bottom area of ​​the vaccine vial to the difference between the bottom area of ​​the water bath chamber and the upper cross-sectional area of ​​the piston rod is equal to the ratio of the bottom area of ​​the power chamber to the bottom area of ​​the height adjustment chamber.

[0007] Furthermore, the extrusion disc is limited and slidably connected to a geometrical component, and the connecting rod near the height adjustment component is provided with equidistant limiting grooves, which are matched with the adjacent geometrical components for limiting.

[0008] Furthermore, the geometric component is made of an elastic material, and the force required for the geometric component to deform is less than the elastic force of the spring between the height adjustment component and the adjacent second extrusion cylinder.

[0009] Furthermore, an L-shaped member is fixedly connected to the side of the geometric member away from the adjacent limiting groove, and the extrusion member is provided with an annular groove. The L-shaped member passes through the adjacent first extrusion cylinder and is limited and engaged with the adjacent annular groove.

[0010] Furthermore, the thickness of the annular groove is greater than the thickness of the L-shaped member on the side adjacent to the first extrusion cylinder.

[0011] Furthermore, a ring-shaped T-shaped member is fixedly connected to the upper side of the support ring, and a sealing rod is slidably connected inside the T-shaped member. The side of the T-shaped member away from the central axis of the adjacent support ring is connected to the adjacent ring-shaped airbag through a conduit. Rubber blocks are fixedly connected to the opposing sides of the ring-shaped sealing rod.

[0012] Furthermore, a compression ball is fixedly connected to the lower side of the support ring near the central axis of the outer shell. A motor is fixedly connected to the piston rod, and a rocking disk is fixedly connected to the output shaft of the motor. The rocking disk is in contact with the support disk. The rocking disk is provided with hemispherical grooves distributed in an annular pattern and respectively compressing with adjacent compression balls. An annular and symmetrical elastic blocks are fixedly connected to the support disk. The symmetrically distributed elastic blocks compress with the side of the adjacent support ring away from the adjacent compression ball. A reset cylinder is fixedly connected to the support disk. A reset disk is slidably connected inside the reset cylinder. A reset element that is limited and rotated by the reset disk is limited and rotated by the reset element. The T-shaped element on one side of the support ring is connected to the reset cylinder near the reset disk through a conduit.

[0013] Furthermore, it also includes a ring-shaped agitator plate, which is fixed to the lower side of the shaking disc.

[0014] This invention discloses the following technical effects: The invention utilizes an expanding annular airbag to separate the water bath solution from the vaccine's neck, preventing the water bath solution from splashing onto the vaccine's mouth during movement, thus reducing the probability of vaccine contamination. During the immersion of the vaccine in the water bath solution, a hydraulically driven support plate moves upward, preventing the vaccine from squeezing the water bath solution out to other parts of the outer casing. A rubber block contacts the vaccine's neck, fixing the vaccine and preventing shaking during movement, which would reduce the contact area between the vaccine and the water bath solution and ensure efficient vaccine warming. A shaking disc and a squeezing ball work together to drive the shaking of the vaccine during the water bath process, while a stirring plate agitates the water bath solution, exchanging substances within the vaccine that exchange heat with the water bath solution, ensuring uniform heating of the vaccine's contents and improving the efficiency of vaccine warming.

Detailed Implementation

[0025] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] When livestock need to be vaccinated, a water bath is usually used to warm the vaccine. However, during the movement of the water bath, the water solution inside the water bath shakes, causing some of the water solution to splash onto the mouth of the vaccine bottle, which can easily contaminate the vaccine. At the same time, the shaking of the water solution inside the water bath also impacts the vaccine in the water bath, which can easily cause the vaccine to tip over inside the water bath, contaminating the vaccine.

[0027] Example 1: A temperature-uniform vaccine warming device, please refer to... Figures 1-4The device includes an outer shell 1, with an electric heating wire (an existing device, not shown in the figure) installed on the inner wall of the outer shell 1 to provide heat for the vaccine to warm up. A sealing cap 2 is threaded to the upper side of the outer shell 1. A support plate 3 is slidably and sealingly connected to the upper part of the outer shell 1. The lower side of the outer shell 1 and the support plate 3 cooperate to form a water bath chamber 301, which contains water bath liquid. Five support rings 4 are spherically connected to the support plate 3. Two symmetrically distributed connecting rods 5 are fixed to the lower side of the support rings 4. The cross-section of the connecting rods 5 is inverted T-shaped. The two symmetrically distributed connecting rods 5 on the same support ring 4 are slidably connected to a squeezing plate 6. The upper part of the squeezing plate 6... The side is sealed to the adjacent support ring 4 to prevent the water bath liquid in the water bath chamber 301 from overflowing. The connecting rod 5 on one side is slidably connected to the first extrusion cylinder 7. The first extrusion cylinder 7 is fixed to the lower side of the adjacent extrusion plate 6. The lower part of the first extrusion cylinder 7 is slidably connected to the extrusion component 8. The extrusion component 8 is slidably connected to the adjacent connecting rod 5. The upper side of the extrusion component 8 cooperates with the adjacent first extrusion cylinder 7 to form an extrusion chamber 801. The extrusion chamber 801 contains gas. The lower side of the extrusion component 8 is fixed to the lower part of the adjacent connecting rod 5. The middle part of the support ring 4 is fixed to an annular airbag 9. The annular airbag 9 is connected to the adjacent extrusion chamber 801 through a conduit.

[0028] Please refer to Figures 2-5 On the other side, a second extrusion cylinder 10 is fixedly connected to the lower part of the connecting rod 5. An adjusting member 11 is slidably connected to the upper part of the second extrusion cylinder 10. The adjusting member 11 is slidably connected to the adjacent connecting rod 5. The lower side of the adjusting member 11 cooperates with the adjacent second extrusion cylinder 10 to form a power chamber 111. Hydraulic oil is stored in the power chamber 111. A spring is fixedly connected between the lower side of the adjusting member 11 and the adjacent second extrusion cylinder 10. A third extrusion cylinder 12 is fixedly connected to the middle of the lower side of the outer shell 1. A piston is slidably connected to the upper and lower parts of the third extrusion cylinder 12. The lower side of piston rod 13 cooperates with the third extrusion cylinder 12 to form a height adjustment chamber 131. Hydraulic oil is stored in the height adjustment chamber 131. The power chamber 111 is connected to the height adjustment chamber 131 through a conduit. The ratio of the difference between the bottom area of ​​the vaccine bottle and the bottom area of ​​the water bath chamber 301 and the upper cross-sectional area of ​​the piston rod 13 is equal to the ratio of the bottom area of ​​the power chamber 111 to the bottom area of ​​the height adjustment chamber 131. This is used to move the support plate 3 upward during the process of immersing the vaccine bottle in the water bath liquid, so as to prevent the water bath liquid from overflowing the support plate 3.

[0029] Please refer to Figures 4-6The middle part of the extrusion disc 6 is connected to a slidable component 14 with upper and lower limits and sealing. The slidable component 14 is made of elastic material. When the height of the slidable component 14 decreases, its length increases. A number of equidistant limiting grooves 141 are provided on the connecting rod 5 near the height adjustment component 11. The limiting grooves 141 cooperate with the adjacent slidable components 14 to limit and accommodate vaccine bottles of different heights. The slidable component 14 is made of elastic material. The force required for the deformation of the slidable component 14 is less than the spring force between the height adjustment component 11 and the adjacent second extrusion cylinder 10, thus controlling the deformation of the slidable component 14 and the sequence of movement of the extrusion disc 6.

[0030] Please refer to Figures 4-7 An L-shaped member 15 is fixedly connected to the side of the L-shaped member 14 away from the adjacent limiting groove 141. An annular groove 151 is provided on the upper part of the extrusion member 8. The lower part of the L-shaped member 15 passes through the adjacent first extrusion cylinder 7 and is limited and engaged with the adjacent annular groove 151 to prevent the annular airbag 9 from inflating and hindering the downward movement of the vaccine bottle when it moves down. The thickness of the annular groove 151 is greater than the thickness of the side of the L-shaped member 15 close to the adjacent first extrusion cylinder 7, so as to facilitate the L-shaped member 15 to limit the adjacent extrusion member 8.

[0031] Please refer to Figure 3 , Figure 8 and Figure 9 Three T-shaped pieces 16 are fixedly connected to the upper side of the support ring 4 in a ring. A sealing rod 17 is slidably connected inside the T-shaped piece 16. The side of the T-shaped piece 16 away from the central axis of the adjacent support ring 4 is connected to the adjacent annular airbag 9 through a conduit. Rubber blocks 18 are fixedly connected to the opposing sides of the annularly distributed sealing rods 17. The rubber blocks 18 are used to contact the vaccine bottle and limit the position of the vaccine bottle.

[0032] Please refer to Figure 2 , Figure 3 and Figure 9A compression ball 19, which is hemispherical, is fixedly connected to the lower side of the support ring 4 and near the central axis of the outer shell 1. A motor 20 is fixedly connected to the upper side of the piston rod 13. A rocking disk 21 is fixedly connected to the output shaft of the motor 20. The rocking disk 21 is in contact with the middle of the lower side of the support disk 3. Several hemispherical grooves 211 are arranged in annularly on the rocking disk 21. The hemispherical grooves 211 are in compression engagement with the adjacent compression balls 19. An annular elastic block 22 is fixedly connected to the support disk 3 and is symmetrically distributed vertically. The symmetrically distributed elastic block 22 is in compression engagement with the side of the adjacent support ring 4 away from the adjacent compression ball 19, which is used to push the adjacent support ring 4 to reset. A reset cylinder 23 is fixedly connected to the middle of the upper side of the 3. A reset plate 24 is slidably connected to the lower part of the reset cylinder 23. A reset component 25 is rotatably connected to the middle of the upper side of the reset plate 24. The reset component 25 is in a limiting fit with the reset cylinder 23. The reset component 25 consists of a cylinder, a knob and two limiting posts. The upper side of the reset cylinder 23 is provided with a groove corresponding to the shape of the cylinder and the two limiting posts of the reset component 25. Initially, the two limiting posts of the reset component 25 are located inside the reset cylinder 23, and the two limiting posts of the reset component 25 do not correspond to the grooves on the reset cylinder 23. The T-shaped piece 16 on one side of the support ring 4 is connected to the lower part of the reset cylinder 23 through a conduit.

[0033] When livestock need to be vaccinated, the farmer takes the vaccine out of the refrigerator and rotates the sealing cap 2 to make the sealing cap 2 lose contact with the outer shell 1. Then, the vaccine is inserted into the outer shell 1 in sequence (the following will describe a set of parts on the left side of the outer shell 1). The farmer inserts the vaccine into the support ring 4 and presses it down. The vaccine first contacts the shaped part 14 and squeezes the shaped part 14 to deform. The deformation of the shaped part 14 causes its right side to move to the right and lose contact with the adjacent limiting groove 141, releasing the limitation on the adjacent connecting rod 5. When the shaped part 14 deforms, its left side drives the L-shaped part 15 to move to the left. The lower part of the L-shaped part 15 passes through the first extrusion cylinder 7 and enters the annular groove 151, limiting the extrusion part 8. Then, the vaccine contacts the extrusion disc 6 and squeezes it downward.

[0034] As the extrusion plate 6 moves downward, it drives the height adjustment component 11 to move downward, compressing the spring between the height adjustment component 11 and the second extrusion cylinder 10 (hereinafter referred to as the spring adjacent to the second extrusion cylinder 10). At the same time, the extrusion plate 6 drives the first extrusion cylinder 7 and the extrusion component 8 to move downward, and compresses the spring between the extrusion component 8 and the adjacent connecting rod 5 (hereinafter referred to as the spring adjacent to the extrusion component 8). As the height adjustment component 11 moves downward, the hydraulic oil in the power chamber 111 enters the height adjustment chamber 131 through the adjacent conduit. The hydraulic oil in the height adjustment chamber 131 pushes the piston rod 13 upward. The piston rod 13 drives the support plate 3 upward through the motor 20 and the rocking plate 21, so that the liquid level of the water bath liquid in the water bath chamber 301 is always coplanar with the lower side of the support plate 3.

[0035] As the vaccine squeezing disc 6 moves downwards, it stops pressing the vaccine when it reaches the middle of the support ring 4 at the bottleneck of the vaccine. Then, the jig 14 quickly resets, and its right side moves to the left. However, since the right side of the jig 14 does not correspond to the adjacent limiting groove 141, it cannot fully reset at this point because it is in contact with the adjacent connecting rod 5. Nevertheless, the jig 14 always tends to reset. Simultaneously, the squeezing disc 6 slowly moves upwards under the reset action of the adjacent spring of the second squeezing cylinder 10 (limited by the flow rate of hydraulic oil in the adjacent conduit of the second squeezing cylinder 10, hence the slow upward movement of the squeezing disc 6). As the squeezing disc 6 drives the jig 14 to slowly move upwards, the right side of the jig 14 gradually aligns with the adjacent limiting groove 141. At this point, the right side of the jig 14 moves to the left under its reset action and enters the adjacent limiting groove 141, limiting the connecting rod 5. The squeezing disc 6 then stops moving upwards, and the bottleneck of the vaccine just passes through the support ring 4 (as shown in the attached figure). Figure 2 (The status of the Chinese vaccine).

[0036] When the geometric component 14 is reset, the left side of the geometric component 14 moves to the right under its reset action, and drives the L-shaped component 15 to move to the right. The L-shaped component 15 loses contact with the annular groove 151 and releases the limit on the extrusion component 8. At this time, the extrusion component 8 moves upward under the action of its adjacent spring, and squeezes the gas in the extrusion chamber 801 into the annular airbag 9 through the conduit, so that the annular airbag 9 expands and contacts the position on the lower side of the vaccine bottleneck, preventing the water bath liquid in the water bath chamber 301 from overflowing through the space between the support ring 4 and the vaccine when the device is vibrated.

[0037] After the annular airbag 9 inflates and adheres to the vaccine, excess gas inside the annular airbag 9 enters the three T-shaped pieces 16 through adjacent conduits. The gas inside the T-shaped pieces 16 pushes the adjacent sealing rods 17 to move. The sealing rods 17 drive the adjacent rubber blocks 18 to move towards the central axis of the support rings 4, eventually contacting the bottleneck of the vaccine and limiting its position. The above steps are then repeated until all support rings 4 contain vaccines. Afterward, the farmer tightens the sealing cap 2 again, then activates the electric heating wire inside the outer casing 1 and sets the motor 20 to start intermittently. The electric heating wire heats the water bath liquid in the water bath chamber 301. The water bath solution is kept at a fixed temperature. At the same time, the output shaft of the motor 20 drives the shaking disk 21 to rotate intermittently. The shaking disk 21 pushes the extrusion ball 19 upward through the hemispherical groove 211, causing the support ring 4 to swing counterclockwise along its center (the rotation angle in this article is from front to back). At the same time, the support ring 4 squeezes the elastic block 22 to deform. When the next hemispherical groove 211 contacts the extrusion ball 19, the support ring 4 swings clockwise and resets under the push of the elastic block 22. In this way, the support ring 4 drives the adjacent vaccine and all its parts to swing, shaking the vaccine and making all parts inside the vaccine evenly heated, thus improving the warming efficiency.

[0038] Upon arrival at the livestock vaccination site, the farmer waits for the vaccine temperature inside the device to rise. Then, the farmer turns off the electric heating wire and motor 20, and unscrews the sealing cover 2. The farmer then rotates the reset piece 25 so that the limiting post on the reset piece 25 aligns with the groove on the reset cylinder 23. The farmer then pulls the reset piece 25 upward, causing the reset plate 24 to move upward. The gas in the adjacent T-shaped piece 16 and the gas in the annular airbag 9 connected to the adjacent T-shaped piece 16 are extracted through the adjacent conduit. This causes the gas in the T-shaped piece 16 to move the adjacent sealing rod 17. The sealing rod 17 then moves the adjacent rubber block 18 and causes it to lose contact with the vaccine. At the same time, the annular airbag 9 gradually returns to its original shape and loses contact with the vaccine.

[0039] After the annular airbag 9 loses contact with the vaccine, the farmer gently presses the vaccine, causing the squeezing member 14 to deform and repeating the above steps. This causes the right side of the squeezing member 14 to lose contact with the adjacent limiting groove 141 and releases the limiting on the adjacent connecting rod 5. At this time, the vaccine tends to move upward under the action of the adjacent spring of the second squeezing cylinder 10. Subsequently, the farmer maintains the squeezing of the vaccine and makes it slowly move upward until the squeezing disc 6 is about to reset. Since the lower part of the L-shaped member 15 is located inside the first squeezing cylinder 7, it restricts the squeezing member 8 from resetting. Under the action of the adjacent spring of the second squeezing cylinder 10, the squeezing disc 6 continues to move upward and reset, stretching the spring adjacent to the squeezing member 8. Then the farmer removes the vaccine. At this time, the squeezing member 14 returns to its deformed state, and at the same time, the squeezing member 14 drives the L-shaped member 15 to move out of the first squeezing cylinder 7. The squeezing member 8 moves downward and resets under the action of its adjacent spring.

[0040] As the extrusion plate 6 moves upward, the springs adjacent to the extrusion element 8 gradually reset. Subsequently, the springs adjacent to the extrusion element 8 pull the extrusion element 8 downward relative to the first extrusion cylinder 7, increasing the volume inside the extrusion chamber 801. The gas inside the reset cylinder 23 is extracted through the adjacent conduit, the annular airbag 9, and the T-shaped element 16, causing the reset plate 24 to move downward. After the extrusion plate 6 and the T-shaped element 14 have both reset, the extrusion element 8 moves downward relative to the first extrusion cylinder 7 and resets. Then, the farmer takes out the vaccine from the device in sequence, resetting the reset plate 24 and the reset element 25. Then, the farmer rotates the reset element 25, causing the limiting post of the reset element 25 to misalign with the groove on the reset cylinder 23. Finally, the farmer injects the vaccine into the livestock.

[0041] When using the water bath method to warm up the vaccine, the heat transfer efficiency between the vaccine and the water bath solution is low because the vaccine and the water bath solution are in a relatively static state, resulting in slow vaccine warming up.

[0042] Example 2: Based on Example 1, please refer to... Figure 3 and Figure 9 It also includes several agitator plates 26 arranged in a ring, which are fixed to the lower side of the shaking plate 21.

[0043] When the shaking plate 21 rotates, it drives several stirring plates 26 on its lower side to rotate. The rotation of the stirring plates 26 causes the water bath liquid in the water bath chamber 301 to rotate, thus changing the water bath liquid in contact with the vaccine, improving the heat exchange efficiency between the water bath liquid and the vaccine, and thus shortening the time required for the vaccine to warm up.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
