[0030] With reference to Figures 1 to 3 The embodiments of the utility model propose a kind of anti-sticking quick freezing mechanism, it is applied to the equipment for the quick freezing treatment of blood bag 400 in medical equipment industry, to ensure the quality and long-term preservation of blood products.

[0031] Anti-sticking quick freezing mechanism includes lower cold plate 100, upper cold plate 200 and multiple blocking belts 300, multiple components work cooperatively, realize the efficient quick freezing and anti-sticking of blood bag 400.

[0032] The lower cold plate 100 is the basis of the quick freezing mechanism, and has a flat and smooth upper end surface specially used for bearing the blood bags 400. The lower cold plate 100 serves as an evaporator of the refrigeration system, and the blood bags 400 are placed on the lower cold plate 100 and directly or indirectly contact the lower cold plate 100. After the quick freezer starts to work, the lower cold plate 100 contacts the blood bags to ensure that the temperature of the blood bags 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 adapt to 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 oppositely 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, and the blood bags 400 are placed on the lower cold plate 100 and directly or indirectly contact the lower cold plate 100. After the quick freezer starts to work, the lower cold plate 100 contacts the blood bags. The upper cold plate 200 can be lifted and lowered to form a gap between the upper cold plate 200 and the lower cold plate 100 to facilitate the blood bags 400 to enter and exit. After the upper cold plate 200 and the lower cold plate 100 are closed to contact the blood bags 400, the quick freezing operation is performed. The upper cold plate 200 and the lower cold plate 100 are provided with a blood bag 400 entry and exit side to facilitate the transfer of the blood bags 400 by automatic equipment such as a mechanical hand.

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

[0035] The operation principle of the anti-sticking quick freezing mechanism is as follows:

[0036] During the quick freezing operation, the blood bags 400 are first arranged in an orderly manner on the upper end surface of the lower cold plate 100. Then, the upper cold plate 200 is lowered to a position closed to the lower cold plate 100, the blood bags 400 contact the lower cold plate 100 and the upper cold plate 200, and the quick freezer starts to work to quickly freeze the blood bags 400 through the lower cold plate 100 and the upper cold plate 200. During the quick freezing process, the blocking belt 300 is located between the upper cold plate 200 and the blood bags 400 to play a key isolation role.

[0037] After the quick freezing is completed, the upper cold plate 200 is raised. 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, as the upper cold plate 200 is raised, the blocking belt 300 is also raised and separated from the blood bags 400, so that the blood bags 400 can be easily taken out. Figure 1Therefore, when the upper cold plate 200 rises, the blocking belt 300 will be stretched into an inclined state, and the blocking belt 300 will peel the blood bag 400 off the upper cold plate 200, preventing the blood bag 400 from adhering to the upper cold plate 200, achieving automatic separation of the blood bag 400, and meeting the use requirements of automatic equipment.

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

[0039] 1. Anti-sticking: The blood bag 400 is peeled off by the blocking belt 300, solving the problem that the blood bag 400 is easy to adhere to the upper cold plate 200 after quick freezing, not only improving the efficiency and quality of quick freezing operation, but also reducing the risk of blood bag 400 damage and blood contamination caused by adhesion.

[0040] 2. Automated production: The design of the quick-freezing mechanism is reasonable and easy to realize automated production. By adjusting the number and position of the blocking belt 300, it can adapt to the processing needs of different specifications and quantities of blood bags 400. At the same time, the opening and closing operation of the upper cold plate 200 and the lower cold plate 100 is 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 the production efficiency. This is of great significance to meet the high demand and rapid supply of blood products in the medical industry.

[0042] 4. Reduce costs: By reducing the risk of blood bag 400 adhesion and damage, the utility model reduces the additional costs caused by processing unqualified blood bags 400. At the same time, automated production also reduces the dependence on manual operation, further reducing production costs.

[0043] The anti-sticking quick-freezing mechanism has significant technical effects and advantages, and is particularly suitable for quick freezing treatment of blood bags 400 in the medical industry. By setting the blocking belt 300, the blocking belt 300 and the upper cold plate 200 and the lower cold plate 100 work together to achieve efficient and 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 high-strength material which is not easy to deform at low temperature, such as nylon or polyester fiber, to ensure that the mechanical properties are good at low temperature. 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 rapidly frozen, the upper cold plate 200 rises, and at this time the blocking belt 300 is tensioned. The blocking belt 300 does not block the blood bag 400, so that the blood bag 400 is placed on the upper end surface of the lower cold plate 100. Then, the upper cold plate 200 is lowered, and at this time the blocking belt 300 is in a loose state and does not affect the rapid freezing of the blood bag 400.

[0045] After the rapid freezing operation is completed, the upper cold plate 200 rises again, and the blocking belt 300 is tensioned again. In the process of tensioning, the blocking belt 300 gradually separates from the upper cold plate 200, so that the blood bag 400 is peeled off from the upper cold plate 200. Moreover, the blocking belt 300 in the tensioned state has strong pulling force, which helps to peel off the blood bag 400 from the upper cold plate 200.

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

[0047] On the edge or lower end surface of the upper cold plate 200, a set of tightness adjusting assemblies 210 are installed. By operating the tightness adjusting assemblies 210, the tightness of the blocking belt 300 can be flexibly adjusted according to the size and number of the blood bags 400. The tightness adjusting assemblies 210 can be designed in the form of a screw adjusting rod, a ratchet mechanism or an electric driver, and the pre-tightening or loosening of the blocking belt 300 can be realized by rotating or key operation.

[0048] Referring to Figure 5 In some embodiments of the present application, the tightness adjusting assembly 210 includes an adjusting seat 211 and an adjusting block 212. The adjusting seat 211 can be fixed on the inlet and outlet side of the upper cold plate 200 or the non-inlet and outlet side of the lower cold plate. Alternatively, the adjusting seat 211 is fixed on the lower end surface of the inlet and outlet side of the upper cold plate 200 or the upper end surface of the non-inlet and outlet side of the lower cold plate. The adjusting seat 211 is provided with a sliding groove 213, and the adjusting block 212 is arranged in the sliding groove 213. The adjusting seat 211 is connected with a fastener to lock the adjusting block 212. One end of the blocking belt 300 is fixed to the adjusting block 212. By changing the position of the adjusting block 212, the tightness of the blocking belt 300 can be adjusted.

[0049] As Figure 5As shown, the length direction of the sliding groove 213 is the same as or similar to the extension direction of the blocking belt 300, and the fastener is a bolt. By screwing the bolt, the adjusting block 212 can be driven to move in the sliding groove 213, so as to adjust the tightness of the blocking belt 300. In addition, the adjusting block 212 can also be rotated to wind the blocking belt 300, so as to adjust the tightness of the blocking belt 300, and then the adjusting block 212 can be locked by using the fastener.

[0050] In some embodiments, one end of the blocking belt 300 is fixed on the lower cold plate 100, and the other end is connected to the tightness adjusting assembly of the upper cold plate 200 through a pulley or a guide. During the lifting and lowering of the upper cold plate 200, the blocking belt 300 can automatically adapt to the distance change between the upper and lower cold plates 100, while maintaining appropriate tension. In addition, the tightness adjusting assembly also allows fine adjustment of the blocking belt 300 without interrupting the quick freezing process, so as to adapt to blood bags 400 of different specifications, and ensure the best quick freezing effect and safety.

[0051] Referring to Figure 2 and Figure 3 , a plurality of blocking belts 300 are arranged in parallel to each other, the distribution direction of the blocking belts 300 is consistent with the in-out direction of the blood bags 400, the blocking belts 300 are arranged along the in-out direction of the blood bags 400, and usually the blood bags 400 are also arranged according to the in-out direction. A single blocking belt 300 or a plurality of blocking 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 blocking belt 300 or a plurality of blocking belts 300. According to actual needs, the number of the blocking belts 300 can be increased or decreased, and the distance between adjacent blocking belts 300 can be adjusted, so as to adapt to blood bags 400 of different specifications, sizes and quantities.

[0052] Further, the distance between the adjacent two blocking belts 300 can be set to be less than the width of the blood bag 400, so that there is at least one blocking belt 300 on the upper side of each blood bag 400, and the situation that the blood bag 400 directly adheres to the upper cold plate 200 is avoided, and the blood bag 400 cannot be peeled off from the upper cold plate 200 after quick freezing is prevented.

[0053] Referring to Figure 4 It can be understood that in some embodiments of the present application, the blocking belt 300 is connected with a plurality of horizontal belts 310, and the plurality of blocking belts 300 and the plurality of horizontal belts 310 are interwoven into a grid shape. After the quick freezing operation is completed, the grid-shaped structure can better peel the blood bags 400 from the upper cold plate 200. 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 blocking belt 300 and the horizontal belt 310 at the same time, so as to leave the upper cold plate 200. The stress of the blood bag 400 is more dispersed and balanced, and the probability of breaking of the blood bag 400 is reduced.

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

[0055] The material and specifications of the horizontal bands 310 should match the blocking bands 300 to ensure that they still have sufficient rigidity and durability in a low-temperature environment. In addition, the spacing and number of the horizontal bands 310 also need to 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 application, the blocking bands 300 are made of steel wire. Steel wire is chosen as the material of the blocking bands 300 mainly based on its high strength, resistance to deformation and good low-temperature resistance. The surface of the steel wire is smooth and corrosion-resistant, avoiding the risk of embrittlement or fracture in a low-temperature environment. In addition, the steel wire is easy to clean and maintain, meeting the medical and health standards, ensuring the safety and hygiene of the quick freezing mechanism during use.

[0057] In other embodiments of the present application, the blocking bands 300 are made of elastic ropes. The elastic rope is used as the blocking band 300 to provide higher flexibility and adaptability. The elastic rope has good elasticity and wear resistance, and can maintain the separation effect under different loadings. In addition, the elastic rope is relatively simple to install and adjust, and can easily adjust its tension and position according to actual needs, increasing the practicality and convenience of the quick freezing mechanism.

[0058] Referring to Figure 1The quick-freezing mechanism further includes a tray 500 capable of loading a plurality of blood bags 400 and resting on the upper end surface of the lower cold plate 100. The tray 500, as an important component of the quick-freezing mechanism, is designed to carry and position the blood bags 400, improving the efficiency of the quick-freezing operation. Moreover, the tray 500 concentrates multiple blood bags 400 together, allowing automated conveying equipment such as a robot to simultaneously move multiple blood bags 400 through the tray 500, simplifying the operation. The tray 500 is made of food-grade materials such as stainless steel or high-density polyethylene, ensuring stability and durability in a low-temperature environment. Anti-slip patterns or bumps 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 wire frame structure, with the tray 500 resting on the lower cold plate 100, allowing the blood bags 400 to contact the lower cold plate 100, promoting efficient heat transfer. The size and shape of the tray 500 can be customized according to the standard blood bag 400 dimensions, facilitating standardized operations and management. In addition, the design of the tray 500 facilitates quick loading and unloading, improving overall work efficiency.

[0059] The second aspect of the utility model discloses a quick freezer, which comprises the anti-sticking quick-freezing mechanism of the first aspect, and the quick-freezing mechanism comprises 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 specially used for carrying blood bags 400. The upper cold plate 200 is arranged above the lower cold plate 100 and forms a pair of oppositely arranged quick-freezing surfaces with the lower cold plate 100. The upper cold plate 200 can be lifted and lowered to form a certain gap between the upper cold plate 200 and the lower cold plate 100, so as to facilitate the blood bags 400 to enter and exit. After the upper cold plate 200 and the lower cold plate 100 are closed, they contact the blood bags 400 and perform the quick-freezing operation. The upper cold plate 200 and the lower cold plate 100 are provided with a blood bag 400 entry and exit side, so as to facilitate the blood bags 400 to be transferred by automated equipment such as a robot. One end of the blocking belt 300 is connected to the lower cold plate 100 and located on the side away from the blood bag 400 entry and exit side, and the other end of the blocking belt 300 is connected to the blood bag 400 entry and exit side of the upper cold plate 200. The above design enables the blocking belt 300 to be distributed between the upper cold plate 200 and the blood bags 400 during the quick-freezing process, forming an effective isolation.

[0060] During the quick-freezing operation, the blood bags 400 are first arranged neatly on the upper end surface of the lower cold plate 100. Then, the upper cold plate 200 is lowered to a position closed to the lower cold plate 100, the blood bags 400 contact the lower cold plate 100 and the upper cold plate 200, 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 blocking 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 finished, the upper cold plate 200 is lifted, and 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, as shown in Figure 1 Fig. 4, when the upper cold plate 200 is lifted, the blocking belt 300 will be stretched into an inclined state, and the blocking belt 300 will peel the blood bag 400 off the upper cold plate 200, preventing the blood bag 400 from adhering to the upper cold plate 200, achieving automatic separation of the blood bag 400, and meeting the use requirements of automatic equipment.

[0062] As shown in Figure 6 Fig. 5, the quick freezer can be a multi-layered quick freezer, including a plurality of vertically arranged layers, and a plurality of blocking belts 300 are arranged between adjacent two layers, thereby forming the anti-adhesion quick freezing mechanism of the first aspect of the embodiment, and a large number of blood bags can be simultaneously quick frozen. It can be understood that the middle layer can be combined as a whole of the upper cold plate 200 and the lower cold plate 100, or the upper end surface of the layer can be the lower cold plate 100 and the lower end surface can be the upper cold plate 200, both of which can meet the quick freezing requirements.

[0063] The quick freezer also contains all the technical solutions of the anti-adhesion quick freezing mechanism, and has all the technical effects of the anti-adhesion quick freezing mechanism, which will not be repeated here.

[0064] The embodiments of the utility model are described in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments, and within the scope of the knowledge possessed by those skilled in the art, various changes can be made without departing from the purpose of the utility model.
