Description

Technical Field

[0001] This utility model relates to the technical field of mixing devices, and in particular to a split-type heating and mixing device. Background Technology

[0002] In pharmaceutical mixing, it is usually necessary to mix two or more different agents, commonly in the form of powder and liquid or liquid and liquid. To achieve mixing, existing mixing devices typically place the two agents in interlocking syringes and circulate the agents between them by alternately pushing the piston rod. However, when operating at room temperature, existing mixing devices are insufficient for efficiently mixing agents that are difficult to mix or have poor mixing effects, relying solely on circulation. This is especially true for certain drugs that are difficult to mix at room temperature; if they do not readily denature when heated to a predetermined temperature, mixing efficiency can be improved.

[0003] In existing technologies, a common heating method is to use heating wires or similar devices to heat syringe-type drug mixing devices. However, syringe barrels are typically circular, and when changing syringes, the syringe is usually removed as a whole, either upwards, downwards, forwards, or backwards, and then fixed in place after a suitable syringe is replaced. For example, the syringe-type drug mixing devices disclosed in Chinese utility model patents with authorization publication numbers "CN219942418U" and "CN219847392U" both employ this installation method. Typically, the locking mechanism needs to be opened first, the syringe placed in position, and then locked in place vertically or horizontally.

[0004] In this situation, if a heating device is needed to heat the syringe barrel, while heating the lower half is relatively easy, heating the upper half presents a greater challenge. This is because the upper half of the syringe barrel may be suspended, without a frame or cover, making it difficult to effectively install a heating device. Consequently, achieving uniform heating of the entire syringe barrel during drug mixing is challenging, thus affecting the mixing effect of the medication. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the technical problem to be solved by this utility model is to provide a split-type heating and mixing device that can simultaneously mix and uniformly heat two agents within a predetermined temperature range, so as to improve the mixing efficiency of different agents.

[0006] This invention proposes a split-type heating and mixing device, comprising a first heating component and a second heating component. The first heating component is magnetically attached to the top of the second heating component. An axially spaced accommodating two syringes is formed between the first and second heating components, with the inner wall of the accommodating space tightly fitted to the outer wall of the syringes. The first heating component is provided with a first control plate, and the second heating component is provided with a second control plate, with the first and second control plates corresponding in position. The second heating component is electrically connected to a control system. Drive mechanisms for pushing the syringe pistons axially are provided at both ends of the accommodating space. The second control plate and the drive mechanisms are both electrically connected to the control system. When the first heating component is attached to the second heating component, the first and second control plates are electrically connected, causing the control system to control both the first and second heating components to simultaneously heat the two syringes. The control system also controls the drive mechanisms to alternately push the syringe pistons axially, thereby achieving drug mixing.

[0007] Preferably, the first heating component includes a first support portion, a first heat-conducting portion, and a first heating portion. The first heat-conducting portion is snapped onto the first support portion and is attached to the upper half of the outer wall of the syringe. The first heating portion is attached to the bottom of the first heat-conducting portion. The first heating portion is electrically connected to the first control board.

[0008] Preferably, the first support portion has a cavity inside, and the first control board is disposed inside the cavity. The first control board is provided with a plurality of spring pins for electrically connecting with the contacts of the second control board.

[0009] Preferably, a cover plate is snapped onto the top of the cavity, and heat insulation cotton is provided between the cover plate and the first heat-conducting part.

[0010] Preferably, the second heating component includes a second support portion, a second heat-conducting portion, and a second heating portion. The second support portion abuts against the first support portion, the second heat-conducting portion is disposed on the second support portion, and the second heat-conducting portion is attached to the bottom of the second heating portion. The second heat-conducting portion is attached to the lower half of the outer wall of the syringe.

[0011] Preferably, the second support portion includes a support member and a tray. The support member is connected to the housing and abuts against both sides of the second heat-conducting portion. The support member is disposed below the second heating portion, and the support member and the tray are detachably connected.

[0012] Preferably, the first heating element is arranged in a film shape, and the second heating element is arranged in a block shape, so as to improve the vertical space utilization inside the housing.

[0013] Preferably, the first support portion has a first mounting groove for mounting the first heat-conducting block, and the support member has a second mounting groove for mounting the second heat-conducting block, with the first mounting groove and the second mounting groove being disposed opposite to each other.

[0014] The first heat-conducting part has a first groove along the axial direction, and the second heat-conducting part has a second groove along the axial direction. When the first heat-conducting part abuts against the top of the second heat-conducting part, the first groove and the second groove form a receiving space for fitting the outer wall of the syringe.

[0015] Preferably, a plurality of first magnetic blocks are fixedly provided on the bottom wall of the cavity, and the second support portion is provided with second magnetic blocks corresponding to the first magnetic blocks.

[0016] As described above, the split-type heating and mixing device of this utility model has the following beneficial effects:

[0017] This invention magnetically attaches a first heating component to a second heating component, electrically connecting the first and second control boards. The space formed by the first and second heating components, which accommodates the docking of two syringes, effectively encloses the outer walls of the syringes. By controlling the first and second heating components through a control system, both syringes can be uniformly heated simultaneously. After reaching a certain temperature range, the temperature is maintained. Simultaneously, the control system controls a drive mechanism to alternately push the pistons of the two syringes axially. This invention increases the syringe heating rate, thereby effectively improving drug mixing efficiency within a specific temperature range, while reducing the installation difficulty of the first heating component and increasing syringe replacement efficiency.

[0041] It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings of this specification are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the implementation of this utility model. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this utility model, should still fall within the scope of the technical content disclosed in this utility model. Furthermore, the terms such as "upper," "lower," "left," "right," and "middle" used in this specification are merely for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of implementation of this utility model.

[0042] like Figures 1 to 10As shown, an embodiment of a split-type heating and mixing device includes a first heating component 100 and a second heating component 200. The second heating component 200 is fixed inside the housing by a threaded connection. The first heating component 100 is magnetically attached to the top of the second heating component 200, so that the first heating component 100 and the second heating component 200 are arranged vertically, facilitating the assembly and disassembly of the first heating component 100 and the second heating component 200. An axially formed receiving space 300 for docking two syringes 500 is formed between the first heating component 100 and the second heating component 200, and the shape of the receiving space 300 matches the shape of the syringe. When the syringe 500 is installed or replaced, the inner wall of the receiving space 300 fits tightly against the outer wall of the syringe, achieving circumferential wrapping of the syringe barrel, which facilitates uniform heating of the drug inside the syringe barrel. The first heating assembly 100 is equipped with a first control board 110, and the second heating assembly 200 is equipped with a second control board 210, with the first control board 110 and the second control board 210 corresponding in position. The second heating assembly 200 is electrically connected to the control system. The accommodating space 300 has drive mechanisms at both ends along the axial direction for pushing the syringe piston to move axially. Both the second control board 210 and the drive mechanisms 700 are electrically connected to the control system. It should be noted that, to reduce installation difficulty, the first control board does not need to be electrically connected to the control system via wires. When the control system energizes the second control board 210, the first heating assembly 100 is attracted to the second heating assembly 200 under magnetic attraction, thus connecting the contacts of the first control board 110 and the second control board 120 to achieve circuit conduction. The control system can simultaneously and uniformly heat the two syringes 700 using the first heating assembly 100 and the second heating assembly 200.

[0043] In use, the first heating component 100 is detached from the second heating component 200, and the two syringes containing the medicine to be mixed are connected. The medicine mixing includes mixing powder and liquid, or liquid and liquid. Then, the connected syringes are placed horizontally in the receiving groove of the housing 600, which is connected to the receiving space 300. The first heating component 100 is magnetically attached to the top of the second heating component 200, so that the inner wall of the receiving space 300 formed by the first and second heating components 100 and 200 is tightly fitted with the outer walls of the two syringes. At this time, the contacts on the first control board 110 and the second control board 210 are connected. The control system controls the first heating component 100 and the second heating component 200 to simultaneously and evenly heat the two syringes 700 to a predetermined temperature range and maintain the temperature. Simultaneously, the control system synchronously controls the drive mechanism to alternately push the syringe pistons axially, thereby achieving rapid medicine mixing. When the syringe needs to be replaced, the first heating element 100 can be easily removed from the second heating element 200 because it is fixed by magnetic attraction, which improves the efficiency of syringe replacement.

[0044] To further describe the heating effect of the first heating component 100 and the second heating component 200 on the syringe, this embodiment provides four different heating methods for the syringe, and the specific effect data are shown in Table 1 and... Figure 19 As shown.

[0045] It should be noted that in Table 1, the control group heats the bottom of the syringe sidewall using a regular heating block; experimental group 1 heats the bottom and front and back sides of the syringe sidewall; experimental group 2, based on experimental group 1, wraps the top of the syringe with insulating material; and experimental group 3 heats the syringe by wrapping it with the first heating component and the second heating component.

[0046] Table 1

[0047]

[0048] From Table 1 and Figure 19 As shown, experimental group 3 in this embodiment (using two heating modules, one above the other) has the fastest heating speed, reaching over 40°C in just 5 minutes, with a significantly higher heating rate compared to other experimental groups.

[0049] In one embodiment, such as Figures 10 to 14As shown, the first heating assembly 100 includes a first support portion 120, a first heat-conducting portion 130, and a first heat-conducting portion 140. The first heat-conducting portion 130 is snapped onto the first support portion 120 and is attached to the upper half of the syringe outer barrel wall. In this embodiment, the first heating portion 140 is preferably attached to the bottom surface of the first heat-conducting portion 130, and the contacts of the first heating portion 140 and the first control board 110 are connected by wires. The first heating portion 140 is film-shaped, and in this embodiment, it is preferably a PI heating film (polyimide heating film). The first support portion 120 is made of rigid plastic material.

[0050] When the first control board 110 and the second control board 210 make contact, the current flowing to the second control board 210 flows through the first control board 110 and then through the wire to the first heating part 140, so that the first heating part 140 heats the upper half of the outer wall of the syringe, and in conjunction with the second heating group 200, increases the heating rate of the syringe.

[0051] In one embodiment, such as Figure 12 and Figure 16 As shown, the first support portion 120 has a cavity 121 inside, and a first control plate 110 is provided inside the cavity 121. The first control plate 110 is provided with a plurality of spring pins 123 for electrically connecting with the contacts of the second control plate (e.g., Figure 10-1 (As shown). In this embodiment, the number of first control plates 110 matches the number of syringes, and the arrangement of the first control plates 110 is not further limited. The first control plate 110 is located directly above the second control plate 210. After the first support part 120 is fully installed, the spring needle on the first control plate 110 contacts the contact point of the second control plate 210. Under the action of magnetic attraction, the end of the spring needle 123 retracts a certain distance, so that the first control plate 110 and the second control plate 210 are electrically connected, avoiding connection through wires. This embodiment can effectively improve assembly efficiency.

[0052] In one embodiment, such as Figure 5 As shown, a plurality of first magnetic blocks 124 are fixedly disposed on the bottom wall of the cavity 121, and the second support portion 220 is provided with second magnetic blocks 126 corresponding to the first magnetic blocks 124. In this embodiment, the number of first magnetic blocks 124 is not further limited, as long as the first heating component 100 can be evenly and uniformly attached to the second heating component 200. Preferably, in this embodiment, the first magnetic blocks 124 are arranged in an array within the cavity 121, and the second magnetic blocks 126 are disposed on the second support portion 220 in a one-to-one correspondence with their positions, thereby facilitating the assembly and disassembly of the first heating component. Simultaneously, the arrangement of the first magnetic blocks 124 and the second magnetic blocks 126, combined with the docking of the first control board and the second control board, allows for coordinated operation, thereby achieving efficient docking between the first heating component 100 and the second heating component 200.

[0053] Furthermore, such as Figure 6 and Figure 7 As shown, a cover plate 400 is snapped onto the top of the cavity 121, and heat insulation cotton 150 is provided between the cover plate 400 and the first heat-conducting part 130 to ensure a good heat preservation effect.

[0054] In one embodiment, such as Figure 5 , Figures 10 to 14 As shown, the second heating assembly 200 includes a second support portion 220, a second heat-conducting portion 230, and a second heating portion 240. The second support portion 220 is fixed inside the housing 600 by a threaded connection and abuts against the first support portion 120. The second heat-conducting portion 230 is disposed on the second support portion 220 and adheres to the bottom of the second heating portion 240, and is also adhered to the lower half of the outer wall of the syringe. The second heating portion 240 is bonded to the bottom of the second heat-conducting portion 230 with silicone thermally conductive adhesive, effectively improving its thermal conductivity. A heat-insulating cotton 150 is also provided between the second heat-conducting portion 230 and the second support portion 220. The heat-insulating cotton 150 and the second support portion 220 work together to keep the syringe warm. The second heat-conducting part 230 is provided with a cavity that can accommodate the second heating part 240. The heat insulation cotton 150 is attached to the bottom of the second heating part 240, which effectively reduces the vertical shell size and thus improves the vertical space utilization rate inside the shell 600.

[0055] In this embodiment, the second heating element 240 is arranged in a block shape, preferably a PTC heating block. The second heating element 240, in conjunction with the first heating element 140 described above, effectively improves the utilization rate of vertical space inside the housing 600, making the entire device structure more compact.

[0056] In one embodiment, such as Figure 10 and Figure 11 As shown, the second support portion 220 includes a support member 224 and a tray 225. The support member 224 is threadedly connected to the housing 600 and abuts against both sides of the second heat-conducting portion 230. The support member 224 is located below the second heating portion 230, and the support member 224 and the tray 225 are detachably connected, ensuring that the second heat-conducting portion 230 and the second heating portion 240 stably heat the lower half of the syringe. The support member 224 and the tray 225 are made of rigid plastic material, which has good thermal insulation properties.

[0057] In one embodiment, such as Figures 12 to 18As shown, the first support portion 120 has a first mounting groove 125 for mounting the first heat-conducting block, and the support member 224 has a second mounting groove 221 for mounting the second heat-conducting block. The first mounting groove 125 and the second mounting groove 221 are arranged opposite to each other. It can be understood that in this embodiment, in order to meet the docking of the two syringes, the two second mounting grooves 221 are arranged opposite to each other along the axial direction.

[0058] In use, the first heat-conducting part 130 is snapped into the first mounting groove 125, and the second heat-conducting part 230 is placed in the second mounting groove 125 and abuts against the outer edge of the second mounting groove 125 to ensure that the first heat-conducting part 130 and the second heat-conducting part 230 abut against each other and wrap the outer wall of the syringe.

[0059] In one embodiment, such as Figure 9 and Figure 10 As shown, the first heat-conducting part 130 has a first groove 141 along the axial direction, and the second heat-conducting part 230 has a second groove 241 along the axial direction. When the first heat-conducting part 130 abuts against the top of the second heat-conducting part 230, the first groove 141 and the second groove 241 form a receiving space for fitting the outer wall of the syringe, so as to ensure that the syringe heats up quickly and is heated evenly during the heating process, effectively shortening the preheating time.

[0060] In one embodiment, such as Figure 10 and Figure 13 As shown, the support member 224 is provided with a retainer 222 for engaging the syringe connector, and the retainer 222 is located between two second mounting slots 221. Figure 17 As shown, the bottom of the first support portion 120 is provided with a retaining plate, which corresponds to the position of the retaining seat. In use, the docked syringe is placed in the receiving groove of the housing, wherein the syringe connector is placed on the retaining seat 222. When the first support portion 120 is closed on the support member 224, the retaining seat 222 and the retaining plate can effectively restrict the radial movement of the syringe.

[0061] In one embodiment, such as Figures 12 to 18As shown, the first support portion 120 has two sets of first mounting holes 223 for mounting spring pins 123 connected to the first control board. In this embodiment, each set of first mounting holes 223 is arranged in an axial array on one side of each first mounting groove 125. The two sets of first mounting holes 223 can be arranged on the same side or diagonally, and this embodiment is not limited. It should be noted that the first mounting hole 223 is a stepped hole, so that the end of the spring pin can pass through the first mounting hole 223 and contact the contact point of the second control board. The top of the support member 224 has two sets of second mounting holes 226 for the contact point on the second control board 210 to pass through, and the second mounting holes 226 correspond one-to-one with the first mounting holes 223, so that when the first support portion 120 is attached to the support member 224, the spring pin 123 on the first control board contacts the contact point on the second control board to achieve electrical connection.

[0062] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
