[0030] Reference Figures 1 to 3 The embodiment of the present invention provides an anti-sticking quick-freezing mechanism, which is applied to a device for performing quick freezing treatment on a blood bag 400 in the medical equipment industry to ensure the quality and long-term preservation of blood products.

[0031] The anti-sticking quick-freezing mechanism includes a lower cold plate 100, an upper cold plate 200 and a plurality of blocking belts 300. The plurality of components work together to achieve efficient quick freezing and anti-sticking of the blood bag 400.

[0032] The lower cold plate 100 is the basis of the quick freezing mechanism. The lower cold plate 100 has a flat and smooth upper end surface, which is specially used to carry the blood bag 400. The lower cold plate 100 serves as the evaporator of the refrigeration system. The blood bag 400 is placed on the lower cold plate 100 and is in direct or indirect contact with the lower cold plate 100. After the quick freezing machine starts refrigeration, the lower cold plate 100 contacts the blood bag to ensure that the temperature of the blood bag 400 can be quickly reduced during the quick freezing process. The size and shape of the lower cold plate 100 can be adjusted according to actual needs to accommodate blood bags 400 of different specifications and quantities.

[0033] The upper cold plate 200 is arranged above the lower cold plate 100, and forms a pair of relatively arranged quick-freezing surfaces with the lower cold plate 100. Similar to the lower cold plate 100, the upper cold plate 200 also serves as an evaporator of the refrigeration system. The blood bag 400 is placed on the lower cold plate 100, and is in direct or indirect contact with the lower cold plate 100. After the quick-freezing machine starts refrigeration, the lower cold plate 100 contacts and quick-freezes the blood bag. The upper cold plate 200 can be raised and lowered to form a certain gap between the upper cold plate 200 and the lower cold plate 100 to facilitate the entry and exit of the blood bag 400. After the upper cold plate 200 and the lower cold plate 100 are closed, they contact the blood bag 400 to perform the quick-freezing operation. The upper cold plate 200 and the lower cold plate 100 are provided with an entry and exit side for the blood bag 400, so as to facilitate the transfer of the blood bag 400 by automated equipment such as a manipulator.

[0034] The barrier belt 300 is a key component of the present application, which can prevent the blood bag 400 from adhering to the upper cold plate 200 after the quick freezing. One end of the barrier belt 300 is connected to the lower cold plate 100 and is located on the side away from the inlet and outlet side of the blood bag 400, and the other end of the barrier belt 300 is connected to the inlet and outlet side of the upper cold plate 200. The above design enables the barrier belt 300 to be distributed between the upper cold plate 200 and the blood bag 400 during the quick freezing process, forming an effective isolation.

[0035] The operating principle of the anti-stick quick-freezing mechanism:

[0036] When performing quick freezing, firstly, the blood bags 400 are neatly arranged on the upper end surface of the lower cold plate 100. Then, the upper cold plate 200 is lowered to a position closed with the lower cold plate 100, and the blood bags 400 contact the lower cold plate 100 and the upper cold plate 200, and the quick freezer starts to work, and the blood bags 400 are quickly frozen by the lower cold plate 100 and the upper cold plate 200. During the quick freezing process, the barrier belt 300 is located between the upper cold plate 200 and the blood bags 400, playing a key isolation role.

[0037] After the quick freezing is completed, the upper cold plate 200 rises. Since one end of the blocking belt 300 is connected to the lower cold plate 100 and the other end is connected to the upper cold plate 200, Figure 1As shown, when the upper cold plate 200 rises, the blocking belt 300 will be stretched to an inclined state, and the blocking belt 300 will peel the blood bag 400 off the upper cold plate 200 to prevent the blood bag 400 from adhering to the upper cold plate 200, thereby realizing automatic separation of the blood bag 400 and meeting the use requirements of automated equipment.

[0038] The anti-sticking quick-freezing mechanism has the following technical effects:

[0039] 1. Prevent adhesion: The blood bag 400 is peeled off by the blocking belt 300, which solves the problem that the blood bag 400 is easily adhered to the upper cold plate 200 after quick freezing, which not only improves the efficiency and quality of the quick freezing operation, but also reduces the risk of damage to the blood bag 400 and blood contamination caused by adhesion.

[0040] 2. Automated production: The quick freezing mechanism is reasonably designed and easy to realize automated production. By adjusting the number and position of the blocking belts 300, it can meet the processing requirements of blood bags 400 of different specifications and quantities. At the same time, the opening and closing operations of the upper cold plate 200 and the lower cold plate 100 are also easy to control automatically, thereby improving the automation level of the entire quick freezing operation.

[0041] 3. Improve efficiency: The quick freezing mechanism can quickly and effectively complete the quick freezing and separation of the blood bag 400, and is easy to realize automated production, thus greatly improving production efficiency. This is of great significance for meeting the high demand and rapid supply of blood products in the medical industry.

[0042] 4. Reduce costs: By reducing the risk of adhesion and damage of the blood bag 400, the present invention reduces the additional costs incurred by handling unqualified blood bags 400. At the same time, automated production also reduces the reliance on manual operations, further reducing production costs.

[0043] The anti-sticking quick-freezing mechanism proposed in the present invention has significant technical effects and advantages, and is particularly suitable for rapid freezing of blood bags 400 in the medical industry. By setting a blocking belt 300, the blocking belt 300 and the upper cold plate 200 and the lower cold plate 100 work together to achieve efficient, anti-sticking quick-freezing treatment of the blood bag 400, providing strong support for improving production efficiency, reducing costs and ensuring quality.

[0044] Reference Figure 1 and Figure 3The blocking belt 300 is made of a high-strength material that is not easily deformed at low temperatures, such as nylon or polyester fiber, to ensure that it can still maintain good mechanical properties in a low-temperature environment. When the upper cold plate 200 and the lower cold plate 100 are in a separated state, the blocking belt 300 is tensioned. When the blood bag 400 is quickly frozen, the upper cold plate 200 rises, and the blocking belt 300 is tensioned. This makes it possible for the blocking belt 300 to not block the blood bag 400, making it easier to place the blood bag 400 on the upper end surface of the lower cold plate 100. Then, the upper cold plate 200 descends, and the blocking belt 300 is in a loose state, which will not affect the quick freezing of the blood bag 400.

[0045] After the quick-freezing operation is completed, the upper cold plate 200 rises again and the blocking belt 300 is tensioned again. During the tensioning process, the blocking belt 300 is gradually separated from the upper cold plate 200, thereby peeling the blood bag 400 from the upper cold plate 200. Moreover, the tensioned blocking belt 300 has a strong pulling force, which helps to peel the blood bag 400 from the upper cold plate 200.

[0046] It can be understood that in some embodiments of the present invention, the upper cold plate 200 is provided with a tension adjustment component 210, and the blocking belt 300 is connected to the tension adjustment component 210. When the upper cold plate 200 and the lower cold plate 100 are separated, the tension adjustment component 210 can be used to adjust the tightness of the blocking belt 300 to adapt to blood bags 400 of different specifications or other products to be frozen.

[0047] A set of tension adjustment components 210 is installed on the edge or lower end surface of the upper cold plate 200. By operating the tension adjustment components 210, the tightness of the blocking belt 300 can be flexibly adjusted according to the size and number of the blood bags 400. The tension adjustment components 210 can be designed in the form of a spiral adjustment rod, a ratchet mechanism or an electric drive, and the blocking belt 300 can be pre-tightened or loosened by rotation or key operation.

[0048] Reference Figure 5 In some embodiments of the present invention, the tension adjustment component 210 includes an adjustment seat 211 and an adjustment block 212. The adjustment seat 211 can be fixed on the entry and exit side of the upper cold plate 200 or the side of the non-entry and exit side of the lower cold plate, or the adjustment seat 211 is fixed to the lower end surface of the entry and exit side of the upper cold plate 200 or the upper end surface of the non-entry and exit side of the lower cold plate. The adjustment seat 211 is provided with a slide groove 213, and the adjustment block 212 is arranged in the slide groove 213, and the adjustment seat 211 is connected with a fastener to lock the adjustment block 212, and one end of the blocking belt 300 is fixed to the adjustment block 212. By changing the position of the adjustment block 212, the tightness of the blocking belt 300 can be adjusted.

[0049] like Figure 5As shown, the length direction of the chute 213 is the same as or close to the extension direction of the blocking belt 300, and the fastener is a bolt. By turning the bolt, the adjustment block 212 can be driven to move in the chute 213, thereby adjusting the tightness of the blocking belt 300. In addition, the adjustment block 212 can also be rotated to reel in the blocking belt 300 to adjust the tightness of the blocking belt 300, and then the adjustment block 212 can be locked with the fastener.

[0050] In some embodiments, one end of the arresting belt 300 is fixed to the lower cold plate 100, and the other end is connected to the tension adjustment assembly of the upper cold plate 200 through a pulley or a guide, so that during the rising and falling process of the upper cold plate 200, the arresting belt 300 can automatically adapt to the distance change between the upper and lower cold plates 100 while maintaining appropriate tension. In addition, the tension adjustment assembly also allows the arresting belt 300 to be fine-tuned without interrupting the quick freezing process to adapt to blood bags 400 of different specifications, ensuring the best quick freezing effect and safety.

[0051] Reference Figure 2 and Figure 3 , multiple barrier belts 300 are arranged in parallel with each other, and the distribution direction of the barrier belts 300 is consistent with the in-and-out direction of the blood bags 400. The barrier belts 300 are arranged along the in-and-out direction of the blood bags 400. Usually, the blood bags 400 are also arranged in the in-and-out direction. A single barrier belt 300 or multiple barrier belts 300 correspond to a row of blood bags 400. After the quick freezing is completed, the row of blood bags 400 is peeled off from the upper cold plate 200 by using a single barrier belt 300 or multiple barrier belts 300. According to actual needs, the number of barrier belts 300 can be increased or decreased, and the distance between adjacent barrier belts 300 can be adjusted to accommodate blood bags 400 of different specifications, sizes and quantities.

[0052] Furthermore, the distance between two adjacent blocking belts 300 can be set to be smaller than the width of the blood bag 400, ensuring that there is at least one blocking belt 300 on the upper side of each blood bag 400, avoiding the situation where the blood bag 400 is directly attached to the upper cold plate 200, and preventing the blood bag 400 from being unable to separate from the upper cold plate 200 after quick freezing.

[0053] Reference Figure 4 It can be understood that in some embodiments of the present invention, the barrier belt 300 is connected with a plurality of transverse belts 310, and the plurality of barrier belts 300 and the plurality of transverse belts 310 are interwoven into a grid shape. After the quick freezing operation is completed, the blood bag 400 can be better peeled off from the upper cold plate 200 by using the grid structure. The size of the grid can be designed to be smaller than the size of the blood bag 400, so that each blood bag 400 is driven by the barrier belt 300 and the transverse belt 310 at the same time, thereby leaving the upper cold plate 200, and the force on the blood bag 400 is more dispersed and balanced, thereby reducing the probability of the blood bag 400 rupture.

[0054] like Figure 4 As shown, the horizontal belt 310 and the blocking belt 300 may be vertically intersected or obliquely intersected, and the horizontal belt 310 and the blocking belt 300 are fixed together by connecting members (such as metal buckles, sutures or hot melt adhesives) to form a grid structure. The grid structure not only increases the overall strength of the blocking belt 300, but also provides more support points to effectively peel the blood bag 400 from the upper cold plate 200.

[0055] The material and specification of the horizontal belt 310 should match the barrier belt 300 to ensure sufficient rigidity and durability in a low temperature environment. In addition, the spacing and number of the horizontal belts 310 should also be designed according to the size of the blood bag 400 and the quick freezing requirements to achieve the best support effect and space utilization.

[0056] In some embodiments of the present invention, the barrier strip 300 is made of steel wire. The steel wire is selected as the material of the barrier strip 300 mainly because of its high strength, non-deformation and good low temperature resistance. The surface of the steel wire is smooth and corrosion-resistant, avoiding the risk of embrittlement or breakage in a low temperature environment. In addition, the steel wire is easy to clean and maintain, meets medical and health standards, and ensures the safety and hygiene of the quick freezing mechanism during use.

[0057] In other embodiments of the present invention, the blocking belt 300 uses an elastic rope, and the use of the elastic rope as the blocking belt 300 is intended to provide higher flexibility and adaptability. The elastic rope has good elasticity and wear resistance, and can maintain the separation effect under different loads. In addition, the elastic rope is relatively simple to install and adjust, and its tension and position can be easily adjusted according to actual needs, which increases the practicality and convenience of the quick freezing mechanism.

[0058] Reference Figure 1The quick freezing mechanism also includes a tray 500, which can carry multiple blood bags 400 and is placed on the upper end surface of the lower cold plate 100. As an important component of the quick freezing mechanism, the tray 500 is designed to carry and position the blood bags 400, thereby improving the efficiency of the quick freezing operation. Moreover, the tray 500 brings multiple blood bags 400 together, and automated conveying equipment such as a manipulator can move multiple blood bags 400 at the same time through the tray 500, thereby simplifying the operation. The tray 500 is made of food-grade materials, such as stainless steel or high-density polyethylene, to ensure stability and durability in a low-temperature environment. Anti-slip patterns or convex points can be designed on the outer surface of the tray 500 to effectively prevent the blood bags 400 from sliding or shifting during the freezing process. The tray 500 can adopt a wireframe structure, and the tray 500 is placed on the lower cold plate 100, and the blood bags 400 can contact the lower cold plate 100 to promote the effective transfer of cold. The size and shape of the tray 500 can be customized according to the size of the standard blood bag 400, which is convenient for standardized operation and management. In addition, the design of the tray 500 facilitates quick loading and unloading, thereby improving overall work efficiency.

[0059] The second embodiment of the present invention proposes a quick freezing machine, which includes the anti-sticking quick freezing mechanism of the first embodiment, and the quick freezing mechanism includes a lower cold plate 100, an upper cold plate 200 and a plurality of blocking belts 300. The lower cold plate 100 has a flat and smooth upper end surface, which is specifically used to carry the blood bag 400. The upper cold plate 200 is arranged above the lower cold plate 100, and forms a pair of relatively arranged quick freezing surfaces with the lower cold plate 100. The upper cold plate 200 can be raised and lowered to form a certain gap between the upper cold plate 200 and the lower cold plate 100, so as to facilitate the entry and exit of the blood bag 400. After the upper cold plate 200 and the lower cold plate 100 are closed, they contact the blood bag 400 to perform the quick freezing operation. The upper cold plate 200 and the lower cold plate 100 are provided with an entry and exit side for the blood bag 400, so as to facilitate the transfer of the blood bag 400 by automated equipment such as a manipulator. One end of the blocking belt 300 is connected to the lower cold plate 100 and is located at a side away from the inlet and outlet side of the blood bag 400, and the other end of the blocking belt 300 is connected to the inlet and outlet side of the upper cold plate 200 for the blood bag 400. The above design enables the blocking belt 300 to be distributed between the upper cold plate 200 and the blood bag 400 during the quick freezing process, forming an effective isolation.

[0060] When performing quick freezing, firstly, the blood bags 400 are neatly arranged on the upper end surface of the lower cold plate 100. Then, the upper cold plate 200 is lowered to a position closed with the lower cold plate 100, and the blood bags 400 contact the lower cold plate 100 and the upper cold plate 200, and the quick freezer starts to work, and the blood bags 400 are quickly frozen by the lower cold plate 100 and the upper cold plate 200. During the quick freezing process, the barrier belt 300 is located between the upper cold plate 200 and the blood bags 400, playing a key isolation role.

[0061] After the quick freezing is completed, the upper cold plate 200 rises. Since one end of the blocking belt 300 is connected to the lower cold plate 100 and the other end is connected to the upper cold plate 200, Figure 1 As shown, when the upper cold plate 200 rises, the blocking belt 300 will be stretched to an inclined state, and the blocking belt 300 will peel the blood bag 400 off the upper cold plate 200 to prevent the blood bag 400 from adhering to the upper cold plate 200, thereby realizing automatic separation of the blood bag 400 and meeting the use requirements of automated equipment.

[0062] like Figure 6 As shown, the quick freezer can be a multi-layer plate quick freezer, including multiple layers arranged vertically, and multiple blocking strips 300 are arranged between two adjacent layers, thereby forming multiple anti-sticking quick freezing mechanisms of the first embodiment, which can quickly freeze a large number of blood bags at the same time. It can be understood that the layer located in the middle can be an upper cold plate 200 and a lower cold plate 100 combined into one, or the upper end surface of the layer can be used as the lower cold plate 100 and the lower end surface can be used as the upper cold plate 200, both of which can meet the requirements of quick freezing.

[0063] The quick-freezing machine also includes the entire technical solution of the anti-sticking quick-freezing mechanism and has all the technical effects of the anti-sticking quick-freezing mechanism, which will not be described one by one.

[0064] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
