On the other hand, uneven heating of the pharmaceutical soft bags may cause deformation, breakage and other problems, affecting the sealing and stability of the product. In addition, due to the uneven heating of the pharmaceutical soft bags, the temperature difference in different areas of the bag will lead to inconsistent inactivation degree of microorganisms, that is, areas with higher temperature may be able to kill microorganisms more effectively, while areas with lower temperature may not achieve the expected sterilization effect, and the sterilization efficiency is low. Summary of the invention

The ribs formed by the bending of the mesh plate itself can ensure that the entire sterilization tray device is light and thin. At the same time, the ribs formed by the intervals can play a separating role, which can prevent adjacent medicine soft bags from contacting or squeezing each other, resulting in the high-temperature steam being unable to fully contact various parts of the medicine soft bags, so as to ensure the consistency of the sterilization effect and avoid the occurrence of sterilization dead corners. The ribs serve as supports for the neck of the medicine soft bag, which can lift the medicine soft bag slightly upward so that a second gap can be formed between the medicine soft bag and the mesh plate, which is conducive to the high-temperature steam to quickly dissipate through the second gap after passing through the pores on the mesh plate, that is, the air permeability of the sterilization tray device is significantly increased, thereby ensuring the temperature uniformity of the entire sterilization tray device during the high-temperature steam sterilization process.

[0020] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0021] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0022] The following is combined with Figures 1 to 4 , the sterilization tray device provided in the embodiment of the present application is described in detail through specific embodiments and their application scenarios.

[0023] See also Figure 1 and Figure 4 The present application discloses a sterilization tray device, and the disclosed sterilization tray device can provide a accommodating basis for a medicine soft bag during high-temperature steam sterilization, that is, the medicine soft bag can be placed on the sterilization tray device. Specifically, the sterilization tray device includes a frame 100 and a mesh plate 200, wherein the frame 100 is a basic component of the sterilization tray device and can provide an installation basis for the mesh plate 200. Exemplarily, the frame 100 can be a frame-shaped structure formed by enclosing a plurality of side beams 110, for example, it can be a rectangular frame structure, the mesh plate 200 is arranged in the frame 100, and the edge of the mesh plate 200 is connected to the frame 100, and exemplarily, the edge of the mesh plate 200 can be arranged on the inner side of the frame 100 by welding, rivet connection, threaded connection, etc., and the mesh plate 200 is provided with air holes 210 penetrating the mesh plate 200, and when performing high-temperature steam sterilization, the high-temperature steam can pass through the air holes 210 and contact the medicine soft bag carried on the mesh plate 200.

[0024] In the embodiment of the present application, the side beam 110 is a structural member made of stainless steel. For example, the cross-section of the side beam 110 can be rectangular. The mesh plate 200 is a structural member made of aluminum alloy. In this way, when the soft medicine bag is sterilized with high-temperature steam, the mesh plate 200 can support the soft medicine bag. The main body of the frame 100 is made of stainless steel, and the mesh plate 200 is made of aluminum alloy. Compared with the method in which the entire sterilization tray device is made of stainless steel, the weight of the entire sterilization tray device can be effectively reduced, so that the entire sterilization tray device has a light and thin design feature, which can be suitable for multi-layer stacking, so that the loading amount of the same batch of soft medicine bags is larger, and the mesh plate made of aluminum alloy has excellent heat transfer efficiency, which can make the sterilization tray device quickly heat up and achieve the purpose of energy saving.

[0025] For example, in the embodiment of the present application, the side beam 110 can be made of 304 stainless steel, and the mesh plate 200 can be made of aluminum-magnesium alloy. In the related art, the specific heat capacity of stainless steel is generally 0.5 J / g°C, and the density of stainless steel is generally 7.6 g~8.0 g / cm 3 The specific heat capacity of aluminum alloy is usually 0.88J / g°C~0.92J / g°C, and the density of aluminum alloy is usually 2.63g~2.85g / cm 3 Although the specific heat capacity of aluminum alloy is about higher than that of stainless steel (about 1.8 times), stainless steel is heavier than aluminum alloy (about 2.9 times). Therefore, when the temperature is raised by the same amount, the heat absorption ratio of stainless steel and aluminum alloy is 2.9 / 1.8≈1.6 times. Therefore, the mesh plate 200 made of aluminum alloy heats up quickly and has better energy-saving and economic benefits.

[0026] In a preferred embodiment, see Figure 3 The edge of the mesh plate 200 is bent to form a flange 230, and the flange 230 of the mesh plate 200 is folded downward relative to the mesh plate 200, the outer side of the flange 230 is in contact with the inner side of the side beam 110, and the mesh plate 200 is connected and fixed to the frame 100 by rivets. The frame 100 and the mesh plate 200 are fixed by riveting rather than welding of different materials, which can greatly reduce the complex production process of welding of different materials, reduce the production cost and time of the sterilization tray device, and this connection method can reduce the deformation caused by welding, the production and assembly process is more convenient, and the structural stability of the sterilization tray device is better; at the same time, the flange 230 is folded downward relative to the mesh plate 200, so that the bearing surface on the upper side of the mesh plate 200 is smoother, reducing the risk of the soft medicine bag being scratched at the edge.

[0027] For further technical solutions, see Figure 3 The mesh plate 200 has an arc-shaped transition at its flange 230, that is, an arc-shaped transition section is formed between the main part of the mesh plate 200 and the flange 230. With such a configuration, during high-temperature steam sterilization, the mesh plate 200 made of aluminum alloy material will expand due to heat. By providing an arc-shaped transition section, the mesh plate 200 can be adapted to thermal expansion and deformation, thereby avoiding direct extrusion between the mesh plate 200 and the side beam 110 to cause deformation and damage, thereby ensuring the stability of the entire sterilization tray device and extending the service life of the sterilization tray device.

[0028] Please continue to see Figure 1The mesh plate 200 is bent upward to form a plurality of raised ribs 220, the plurality of ribs 220 are distributed along a first direction, and each rib 220 is extended along a second direction, the first direction and the second direction are perpendicular to each other, one of the first direction and the second direction can be the length direction of the entire sterilization tray device, and the other can be the width direction of the entire sterilization tray device, by providing the upwardly raised ribs 220, the mesh plate 200 can disperse stress when carrying a soft bag of medicine, thereby preventing the mesh plate 200 from being deformed or broken due to excessive force, thereby improving the stability and service life of the sterilization tray device.

[0029] At the same time, based on the intermittent protrusion setting of the rib 220, the medicine soft bag can be placed in the area between two adjacent ribs 220, that is, the rib 220 can play a separating role to prevent adjacent medicine soft bags from contacting or squeezing each other, resulting in the high-temperature steam being unable to fully contact various parts of the medicine soft bag, so as to ensure the consistency of the sterilization effect and avoid the occurrence of sterilization dead corners; on the other hand, the rib 220, as a support for the neck of the medicine soft bag, can lift the medicine soft bag slightly upward so that a second gap can be formed between the medicine soft bag and the mesh plate 200, which is conducive to the high-temperature steam to quickly dissipate through the second gap after passing through the pores 210 on the mesh plate 200, that is, the air permeability of the sterilization tray device is significantly increased, so that the entire sterilization tray device can quickly heat up during the high-temperature steam sterilization process, and the temperature uniformity of various parts of the sterilization tray device can be ensured.

[0030] It should be noted that the rib 220 in the embodiment of the present application is formed by partial stamping of the mesh plate 200. In this way, the consistency of the surface finish of the supporting surface on the upper side of the mesh plate 200 can be ensured. Compared with the form of additionally welding reinforcing ribs on the mesh plate 200, the risk of deformation of the mesh plate 200 and wear of the welding parts on the soft medicine bag can be avoided.

[0031] In a further technical solution, the sterilization tray device also includes a rib plate 300, which is extended along the first direction, and the two ends of the rib plate 300 are connected to the frame 100, and the rib plate 300 is located below the mesh plate 200 to support the mesh plate 200. Exemplarily, the rib plate 300 can be a structural member made of aluminum alloy material, and the rib plate 300 can be connected to the lower side of the mesh plate 200 by welding, and the two ends of the rib plate 300 can be supported on the side beam 110. Exemplarily, a lining block 400 is welded and fixed to the side beam 110, and the two ends of the rib plate 300 can be supported on the lining block 400.

[0032] Based on the above technical solution, the ribs 220 on the mesh plate 200 are extended along the second direction, and the rib plate 300 is extended along the first direction. In this way, the ribs 220 and the rib plate 300 form a criss-cross mesh rib structure. This structural design enables the sterilization tray device to disperse the pressure more evenly when bearing force, thereby preventing the mesh plate 200 from being deformed or damaged due to excessive local force.

[0033] In some embodiments of this application, see Figure 1 and Figure 4 The mesh plate 200 has a plurality of first areas 200a and a plurality of second areas 200b, the first areas 200a and the second areas 200b are formed between two ribs 220, or between the ribs 220 and the side beam 110, the first areas 200a and the second areas 200b are alternately distributed along the second direction, the aperture of the pores 210 distributed in the first areas 200a is smaller than the aperture of the pores 210 distributed in the second areas 200b, and the medicine soft bag is supported on the first areas 200a. Under such a setting, the aperture of the pores 210 distributed in the first areas 200a is smaller, so that the pores 210 can be distributed more densely in the first areas 200a, so that the first areas 200a can provide more uniform support for the medicine soft bag, avoid excessive concentration of local pressure to cause indentations on the medicine soft bag, and also enable the high-temperature steam to fully contact the bottom side of the medicine soft bag, thereby effectively killing microorganisms in the infusion soft bag.

[0034] When the soft medicine bag is placed on the first area 200a, the second area 200b can serve as the gap area between two adjacent soft medicine bags. The air holes 210 on the second area 200b have a larger aperture, which can significantly improve the air permeability of the mesh plate 200. When multiple sterilization tray devices are stacked and used, the rapidity of heating the stack of materials in the entire sterilization tray device can be improved, and the heating waiting time of the sterilization tray device can be reduced, thereby achieving the purpose of energy saving. That is to say, by partitioning the mesh plate 200 to open air holes 210 of different sizes, it can not only ensure the stability of the support for the soft medicine bag and the adequacy of the sterilization contact, but also improve the air permeability of the mesh plate 200 and improve the rapidity of heating of the entire sterilization tray device.

[0035] In a further technical solution, the cross-section of the rib 220 perpendicular to the second direction is triangular or quasi-triangular, and the top of the rib 220 is preferably an arc-shaped transition. When the neck of the soft medicine bag is overlapped on the triangular or quasi-triangular rib 220, the supporting effect is more stable. The arc-shaped transition at the top of the rib 220, compared with the right-angle or sharp outer edge design of the top of the rib 220, the arc-shaped transition can better disperse the pressure and reduce the single-point force of the soft medicine bag. When the neck of the soft medicine bag is supported on the rib 220, wear and scratches can be effectively avoided.

[0036] In the embodiment of the present application, a positioning member 120 and a positioning recess 111 are respectively provided on the upper and lower sides of the side beam 110. For example, the positioning member 120 is a columnar structure, the positioning member 120 is provided on the upper side of the side beam 110, and the positioning recess 111 is provided on the lower side of the side beam 110. When multiple sterilization tray devices are stacked, the positioning member 120 is used to position and cooperate with the positioning recess 111 of the sterilization tray device adjacent to the upper side. Through the positioning cooperation between the positioning member 120 and the positioning recess 111, the stability of the sterilization tray device during stacking can be increased, and the pile formed by the sterilization tray device due to steam pressure, mechanical vibration and the like during the sterilization process can be prevented from tipping over, thereby further ensuring the safety of the sterilization process.

[0037] In a further technical solution, a support member 130 is further provided on the side beam 110. For example, the support member 130 may be a columnar structure. When multiple sterilization tray devices are stacked, the support member 130 is used to support the adjacent sterilization tray device above. It should be noted that, based on the supporting effect of the support member 130 on the sterilization tray device above it, there can be a sufficient longitudinal gap between two adjacent sterilization tray devices to avoid the upper sterilization tray device from squeezing the soft medicine bag on the sterilization tray below. At the same time, when the soft medicine bag is placed on the mesh plate 200, there should be a redundant gap between the upper side of the soft medicine bag and the lower side of the mesh plate 200 above. In this way, while avoiding the upper adjacent sterilization tray device squeezing the lower soft medicine bag, the high-temperature steam can also continue to conduct upward through the redundant gap, thereby ensuring the penetration effect of the high-temperature steam when multiple sterilization tray devices are stacked for use.

[0038] The inventor discovered during the research that the side beam 110 is usually a rectangular beam, and multiple side beams 110 are usually connected together by welding. There may be small pores or gaps at the welding points of the side beam 110. During the high-temperature steam sterilization process, the high-temperature steam may enter the side beam 110 through the pores or gaps at the welding points. After the high-temperature steam sterilization is completed and the sterilization tray device needs to be transported and transferred, there is often dripping, which makes the working floor slippery or affects other equipment. Based on this situation, the bottom wall of the side beam 110 is provided with a through hole 112, and the high-temperature steam entering the side beam 110 can be discharged outward through the through hole 112 after condensing into water, thereby reducing the adverse effects of water stains in the side beam 110.

[0039] As can be seen from the foregoing, the cross-section of the side beam 110 of the embodiment of the present application is rectangular. If the two side beams 110 are directly welded together, there will be problems such as inaccurate positioning, inconvenient welding and poor welding stability. Based on this, the frame 100 of the embodiment of the present application can also include an adapter 140. The adapter 140 has two welding planes. The two side beams 110 can be welded and fixed corresponding to a welding plane respectively, and finally connected through the adapter 140, thereby improving the convenience of forming and the stability of the finalization of the entire frame 100. The outer side of the adapter 140 is an arc surface, that is, the adapter 140 can make an arc transition between the two side beams 110, reducing the risk of scratches and scrapes.

[0040] Please continue to see Figure 1 A clamping position 113 is also provided on the side beam 110. The clamping position 113 can be a protruding structure or a recessed structure provided on the side beam 110. For example, the clamping position 113 can be a rectangular groove or a circular hole opened on the side beam 110 to facilitate positioning and clamping by the clamp, thereby increasing the convenience of carrying the sterilization tray device.
