Description
Technical Field
[0001] This utility model relates to the field of medical ice-making technology, specifically a medical saline slush making device. Background Technology
[0002] In the medical field, saline solution is a standard medical supply because its osmotic pressure is roughly the same as that of normal human blood plasma and tissue fluid. Therefore, it is widely used in wound care, intravenous injections, and other scenarios. During surgical procedures, hypothermia is often required to protect limbs or organs. For example, in limb or organ transplant surgeries, tiny ice crystals made from saline solution are often used to wrap and refrigerate the limb or organ to be transplanted. In cardiac surgery, small ice crystals made from saline solution are frequently used for myocardial protection and cardiopulmonary resuscitation. These small ice crystals are primarily used for myocardial protection by providing a low-temperature environment to the heart during surgery, slowing the cardiac metabolic rate, reducing myocardial oxygen consumption, and thus protecting myocardial cells from damage. Saline-soaked ice crystals, as a myocardial protection measure, have significant medical value in cardiac surgery. They help reduce surgical risks, increase surgical success rates, and also aid in postoperative recovery.
[0003] In most hospitals, because saline solution has a lower freezing point than purified water and requires a more sterile environment, there is no specialized equipment to prepare sterile small ice blocks. Traditional medical procedures require manually cutting large blocks of saline solution into smaller ice blocks. This cutting process is not only labor-intensive and makes it difficult to maintain a completely sterile environment, but the cut ice blocks are also easily contaminated. Furthermore, the large ice blocks often have sharp edges, sometimes resembling blades, making wrapping limbs or organs difficult and increasing the risk of injury. Utility Model Content

[0019] (III) Beneficial Effects: Compared with the prior art, this utility model provides a medical saline sorbet manufacturing device, which has the following beneficial effects:
[0020] 1. This medical saline slush making equipment uses a detachable ice-making cylinder for independent ice making, ensuring a sterile environment for producing slush. The rotation of the ice-making cylinder keeps the saline solution inside in constant motion, ensuring heat exchange between the saline solutions and maintaining a uniform heat distribution within the cylinder. This prevents localized overcooling and the formation of large ice blocks inside the cylinder. Simultaneously, the hollow design at the top of the ice-making cylinder prevents damage from volume changes during ice formation and provides a large horizontal area to accommodate more tiny ice particles. These ice particles do not contact the cylinder walls when they reach the upper surface, preventing them from releasing heat and condensing together, thus ensuring ice dispersion. The rotating disc's forward and reverse rotation design prevents a stable liquid flow direction inside the ice-making cylinder, further eliminating the possibility of tiny ice particles condensing and spreading. This ensures that the small ice particles forming inside the ice-making cylinder remain in their initial, tiny freezing state, creating a slush-like texture. After the slush has formed for a period of time, remove the ice-making cylinder from the turntable. At this point, the ice-making cylinder will contain a mixture of ice and water. Depending on your needs, you can discard the liquid saline solution and use only the slush portion, or you can use the saline solution mixed with the slush together.
[0021] This naturally formed ice structure not only has smaller ice particles, allowing for a more snug fit around organs during medical treatment and better refrigeration, but also lacks sharp edges, preventing damage to the organs or limbs being refrigerated. Furthermore, since this ice is formed at 0 degrees Celsius, it will not cause frostbite when refrigerating organs or limbs of living individuals.
[0022] 2. This medical saline slush making equipment, through the design of the refrigeration module and vents within the cold air chamber, allows cold air to be directly and efficiently transferred to the ice-making cylinders inside. The cold air vents are positioned at the same height as the ice-making cylinder racks on the turntable, ensuring that the cold air evenly covers each ice-making cylinder and avoiding localized overheating or overcooling. The rotating design of the turntable causes the ice-making cylinders to continuously change position within the refrigeration chamber, further enhancing the uniformity of the cooling effect. Compared to static refrigeration, this dynamic refrigeration method can more effectively lower the temperature of the saline solution and accelerate its freezing point. The shearing and frictional forces generated during the rotation and stirring process play a crucial role in the formation and distribution of ice crystals. These forces help break larger ice crystal particles into smaller ones and distribute them more evenly in the saline solution. By continuously changing the rotation direction of the turntable, the ice crystals can be further disrupted. The growth direction of the ice is controlled to prevent the formation of large ice blocks. This dynamic control process ensures the fineness and uniformity of the slush product. The motor drives the turntable to rotate through the connecting rod, realizing the automated stirring and cooling of the ice drum. This design not only improves ice-making efficiency but also reduces the labor intensity of medical staff. At the same time, the direct contact between the cold air vent and the ice drum, as well as the uniform distribution of cold air in the cooling chamber, accelerate the cooling process of the saline solution and shorten the ice-making time. The lid of the ice drum, the parts that come into contact with the hands, and the ice drum frame are all made of high-polymer materials. These materials have good heat insulation properties and low-temperature resistance, which can prevent low-temperature damage when in contact with the hands. The entire ice-making process is highly automated. Medical staff only need to put the ice drum into the ice maker, set the parameters, and wait. This convenient operation method improves the work efficiency of medical staff.
[0023] 3. This medical saline slush making equipment, through the array of rectangular grid holes on the ice-making cylinder frame, not only ensures that the ice-making cylinder can directly contact the cold air, but also achieves efficient heat exchange between the cold air and the saline through the optimization of the grid hole area (not less than 70% and not more than 80% of the surface area of the ice-making cylinder frame). This design ensures sufficient cold air flow area while maintaining the structural strength of the ice-making cylinder frame. Even if the frame is damaged during rotation, the gapless design between the outer and inner ice-making cylinders further improves heat exchange efficiency. Because the outer wall of the inner ice-making cylinder is in close contact with the inner wall of the outer ice-making cylinder, the cold air can be more effectively transferred to the saline, accelerating the cooling process of the saline. Due to the rotation of the ice-making cylinder on the turntable, the grid holes... The design also promotes the uniform flow of cold air around the ice maker, further enhancing the uniformity of the cooling effect. The gapless design between the outer and inner ice maker cylinders not only improves heat exchange efficiency but also enhances the structural stability and durability of the ice maker cylinder. Since there are no gaps between them, deformation or damage caused by thermal expansion and contraction is avoided. The grid design makes it easier to clean and maintain the ice maker cylinder and frame. Because the grid holes are through holes, cold air can pass through smoothly, and it is also easy for cleaning fluid or cleaning tools to enter, thereby effectively cleaning the inside of the ice maker cylinder and frame. In addition, the ice maker cylinder consists of a cap, an outer ice maker cylinder, and an inner ice maker cylinder. This modular design also facilitates disassembly and assembly, further simplifying cleaning and maintenance.
[0024] 4. This medical saline slush making device features interlocking threads on the openings of the inner and outer ice-making cylinders. This design ensures a tighter fit during connection, improving sealing performance. Additionally, the inner wall of the cylinder cover also has threads corresponding to those on the outer and inner ice-making cylinders, and a sealing ring is provided at the opening where it contacts the inner ice-making cylinder, further enhancing the sealing effect. This design prevents cold air leakage during refrigeration, ensuring optimal cooling. Furthermore, the circular array of locking blocks on the side of the cylinder cover engages with the annular groove on the outermost connecting post of the ice-making cylinder frame, ensuring stable fixation of the ice-making cylinder when placed in the frame. This design not only prevents the ice-making cylinder from shaking or falling off during rotation, but also... It also ensures that the cold air can be evenly distributed into the ice maker. The inward-curving protrusions create a stirring effect during rotation, helping to break down the existing ice crystal structure and disperse it into smaller particles, further improving the quality of the slush. The tail fin at the end of the outer ice maker not only increases the surface area of the outer ice maker but also improves its structural strength through the circumferential array of reinforcing ribs. This design allows the ice maker to be more stably fixed on the ice maker frame during rotation, preventing deformation or damage caused by rotation. At the same time, the turntable has a recess with the same shape as the tail fin. This design not only facilitates the placement and fixation of the ice maker but also ensures the stability of the ice maker during rotation.
[0025] 5. This medical saline slush making equipment utilizes a ventilated base plate at the bottom of the refrigeration chamber to allow cold air to flow smoothly into and out of the refrigeration chamber, providing the necessary cooling conditions for the ice-making process. Simultaneously, the first radiator below the ventilated base plate effectively lowers the temperature of the air inside the refrigeration chamber, ensuring a continuous and stable cooling effect. The heat dissipation chamber and second radiator located at the bottom of the ice maker body constitute a highly efficient heat dissipation system. Heat generated by the first radiator during the refrigeration process can be quickly dissipated through the heat dissipation chamber and second radiator, preventing heat loss. The accumulation of cold air inside the ice maker ensures its long-term stable operation. The ventilated bottom plate design not only ensures smooth airflow but also improves heat exchange efficiency by increasing the contact area with the cooling chamber. This allows the cold air to exchange heat more fully with the saline solution in the ice cylinder, accelerating the formation of ice crystals and the preparation of shaved ice. The heat dissipation chamber is open at both ends and equipped with a vent plate. The densely packed holes on the vent plate effectively promote airflow and heat dissipation. This design not only improves heat dissipation efficiency but also avoids overheating problems caused by poor heat dissipation. Attached Figure Description

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0042] Please see Figures 1-6 A medical saline slush making device includes an ice maker body 1, a refrigeration chamber 11 inside the ice maker body 1, and an ice-making cylinder 12 sealed with saline solution inside the refrigeration chamber 11. The ice-making cylinder 12 is a container for making slush, and cold air is introduced into the refrigeration chamber 11. This part of the structure is the same as the principle and structure of a traditional refrigerator, and will not be described in detail here.
[0043] In this embodiment, the cooling chamber 11 is provided with a rotating turntable 13 that rotates in both directions. The ice-making cylinder 12 is detachably assembled with respect to the turntable 13. The ice-making cylinder 12 is mounted on the turntable 13. The turntable 13 drives the ice-making cylinder 12 to rotate in both directions along a horizontal rotation axis. The horizontal rotation axis refers to a horizontal rotation axis or a rotation axis with a small angle to the horizontal axis. It is necessary to ensure that a horizontal cavity is maintained above the physiological saline inside the ice-making cylinder 12 during the rotation process.
[0044] A medical saline slush making device includes an ice maker body 1, which has a structure similar to that of a refrigerator. The ice maker body 1 contains a cooling chamber 11 and a cold air chamber 21. The cooling chamber 11 holds an ice cylinder 12 filled with saline solution. The cold air chamber 21 contains a cooling module that circulates cold air into the cooling chamber 11. A vertically arranged array of turntables 13 is provided on the inner wall of the cooling chamber 11, and the turntables 13 pass through the wall of the cooling chamber 11 and extend from the back of the ice maker body 1. (See reference...) Figure 4 and Figure 7 The turntable 13 located inside the cooling chamber 11 is rotatable and is provided with an ice-making cylinder rack 132 for placing ice-making cylinders 12. The ice-making cylinder rack 132 rotates with the turntable 13. A motor 131 is provided on the back of the ice maker body 1. The motor 131 is connected to the rotatable part of the turntable 13 through a connecting rod 134 and drives it to rotate. A cold air port 14 communicating with the cold air chamber 21 is provided on the inner wall of the side of the cooling chamber 11. The number of cold air ports 14 is the same as that of the turntable 13, and the horizontal height is the same. An air pump 22 is provided at the corresponding position of the cold air port 14 in the cold air chamber 21. When the motor 131 drives the turntable 13 to rotate, it changes the direction of rotation every 10-15 seconds. During the rotation of the turntable 13, the ice-making cylinders 12 located on the ice-making cylinder rack 132 can come into contact with the cold air sprayed from the cold air port 14.
[0045] Medical personnel add a certain amount of saline solution to the inner ice-making cylinder 123, but not completely fill it. The inner ice-making cylinder 123 is then placed inside the outer ice-making cylinder 122, and the cylinder cap 121 is rotated on to seal and secure it. The entire ice-making cylinder 12 is then placed into the ice-making cylinder frame 132 within the cooling chamber 11 of the ice maker body 1. The cooling chamber 11 has a cold air vent 14 on its side, which is positioned at the same height as the ice-making cylinder frame 132 on the turntable 13, allowing cold air to be sprayed onto the ice-making cylinder 12. Because the ice-making cylinder frame 132 is located on the rotatable part of the turntable 13, the turntable 13 is driven by a motor 131 and a connecting rod 134, causing the ice-making cylinder frame 132 to rotate. The ice-making cylinder 12 rotates within the cooling chamber 11, receiving cold air ejected from the cold air outlet 14. This allows for uniform cooling, lowering the temperature below the freezing point, causing a phase change in water—from liquid to solid. As the temperature decreases, water molecules in the saline solution begin to slow their movement, gradually approaching the freezing point. Near the freezing point, the intermolecular forces strengthen, and tiny ice crystal nuclei begin to form. When the temperature drops below the freezing point, these nuclei rapidly grow into ice crystals. The rotating ice-making cylinder 12 generates shear force and agitation, breaking down larger ice crystals into smaller particles. The saline solution also rotates and flows within the cylinder, creating a stirring effect, which helps to... Breaking down the existing ice crystal structure and dispersing it into smaller particles, the ice crystals in the saline solution are distributed as the ice-making cylinder 12 rotates in a certain direction. However, prolonged rotation in one direction may cause ice crystals to aggregate in certain areas, forming larger ice crystal clumps. Changing the rotation direction can further disrupt the growth direction of the ice crystals, preventing them from forming larger ice blocks. Changing the rotation direction can disrupt this aggregation trend, making the ice crystals more evenly distributed within the cylinder and preventing them from forming larger ice blocks. The shearing and frictional forces generated by the rotation and agitation have a significant impact on the formation and distribution of ice crystals. These forces help break larger ice crystal particles into smaller particles and make them more uniform. The ice crystals are distributed in the saline solution. Over time and with continuous rotation and stirring, the ice crystals in the saline solution gradually become smaller and more uniform. When the ice crystals are small enough and evenly distributed, a slush-like product is formed. Medical staff can then remove the ice container 12 and pour out the slush for use. In addition, rotation and stirring can promote the transfer and distribution of heat, making the temperature in the saline solution more uniform. This helps to avoid abnormal ice crystal growth caused by local overheating or overcooling. Furthermore, the lid 121 of the ice container 12, the parts that come into contact with the hands during use, and the ice container frame 132 are made of polymer materials to prevent injury from residual low temperatures when in contact with the hands.
[0046] To ensure the formation of a fine slush from the saline solution within the ice-making cylinder 12, the temperature of the refrigeration environment must be sufficiently low to allow the saline solution to rapidly reach below its freezing point and undergo a phase change. This is a fundamental condition for ice crystal formation. Simultaneously, the stability and uniformity of the refrigeration environment are also crucial. Excessive temperature fluctuations or uneven distribution can lead to inconsistent ice crystal growth rates, affecting the fineness of the slush. By setting the cold air vent 14 and the rotating disc 13 at the same height, the cold air ejected from the vent 14 forms an airflow around the ice-making cylinder, resulting in a more uniform temperature drop. Furthermore, the cold air coming out of the vent comes into contact with the ice-making cylinder 12, increasing ice-making efficiency. Changing the rotation direction not only enhances the stirring effect but also promotes the dispersion and uniform distribution of ice crystals. This helps prevent excessive accumulation of ice crystals in certain areas, preventing the formation of large ice blocks. By continuously changing the rotation direction and adjusting parameters such as stirring intensity and time, the growth process and distribution of ice crystals can be precisely controlled, thereby producing a fine slush product that meets the required specifications.
[0047] See Figures 6-7 The ice-making cylinder frame 132 has an array of rectangular through holes. The area of the through holes is not less than 70% and not more than 80% of the surface area of the ice-making cylinder frame 132. This allows cold air to pass through the ice-making cylinder frame 132 and contact the ice-making cylinder 12 while providing structural strength to prevent damage during rotation. The ice-making cylinder 12 consists of a cylinder cover 121, an outer ice-making cylinder 122, and an inner ice-making cylinder 123. After adding physiological saline to the inner ice-making cylinder 123... The ice is placed in the outer ice-making cylinder 122 and sealed tightly by the cylinder cover 121. There is no gap between the outer ice-making cylinder 122 and the inner ice-making cylinder 123. The outer wall of the inner ice-making cylinder 123 is in close contact with the inner wall of the outer ice-making cylinder 122. At the same time, the ice-making cylinder frame 132 is provided with a uniformly arrayed grid hole, which allows the ice-making cylinder 12 to directly contact the cold air. The absence of gaps between the outer ice-making cylinder 122 and the inner ice-making cylinder 123 improves the heat exchange efficiency between the saline solution and the cold air in the ice-making cylinder 12.
[0048] See Figures 8-9 The ice-making inner cylinder 123 is longer than the ice-making outer cylinder 122. When the ice-making inner cylinder 123 is inserted into the ice-making outer cylinder 122, the opening of the ice-making inner cylinder 123 exceeds the opening of the ice-making outer cylinder 122. The portion of the ice-making inner cylinder 123 that exceeds the opening of the ice-making outer cylinder 122 is threaded. The opening width of the ice-making outer cylinder 122 is greater than that of the ice-making inner cylinder 123, and it is threaded on the side of the opening. The cylinder cover 121 is convex in shape, and its inner wall is provided with threads corresponding to those of the ice-making outer cylinder 122 and the ice-making inner cylinder 123. A sealing ring is provided inside the cylinder cover 121 at the position where it contacts the opening of the ice-making inner cylinder 123, so that the cylinder cover 121 can seal and fix the ice-making inner cylinder 123 and the ice-making outer cylinder 122.
[0049] See Figures 10-13The cap 121 has a circumferential array of locking blocks 1211 on its side. The outermost part of the ice-making cylinder frame 132 has a connecting post 1321, and the connecting post 1321 has an annular groove 133. The annular groove 133 is circular in shape and has a groove with the same shape as the locking block 1211. When the ice-making cylinder 12 is placed in the ice-making cylinder frame 132, the locking block 1211 can be locked into the groove of the annular groove 133. The tail end of the ice-making outer cylinder 122 has a tail fin 1221. The tail fin 1221 is a circular protrusion with reinforcing ribs arranged in a circular array on the side of the protrusion. The turntable 13 has a recess with the same shape as the tail fin 1221. The ice-making inner cylinder 123 has a groove 1231 on its side. The groove 1231 is recessed inward, and there are protrusions on the inner wall of the ice-making inner cylinder 123 due to the inward recess of the groove 1231. The cooperation between the tail fin 1221 and the locking block 1211 ensures the synchronous rotation of the ice-making cylinder 12 and the turntable 13.
[0050] See Figures 1-5 The bottom of the cooling chamber 11 is provided with a ventilated bottom plate 111, which is connected to the cold air chamber 21 below. A first radiator 23 is provided below the ventilated bottom plate 111. The first radiator 23 is used to cool and reduce the air temperature inside the cold air chamber 21. The bottom of the ice maker body 1 is provided with a heat dissipation chamber, and a second radiator 24 is provided inside the heat dissipation chamber. The heat generated by the first radiator 23 during cooling is discharged from the second radiator 24. The heat dissipation chamber is open from front to back and is provided with a vent plate 102. The vent plate 102 is densely covered with through holes.
[0051] See Figure 14 In specific design, the cross-sectional structure of the ice-making cylinder 12 and ice-making cylinder frame 132 can also be designed as an ellipse. During rotation, the elliptical ice-making cylinder 12 causes the level of the saline solution to change, simultaneously altering the cavity above the saline solution. This reduces the accumulation of slush during rotation, resulting in a finer slush. Furthermore, due to the change in the saline solution level, its center of gravity (…) Figure 14 The black circular shape in the middle will also move up and down, causing it to sway up and down. Moreover, during the formation of saline solution inside the ice-making cylinder 12, the ice shavings are all gathered in the upper part of the ice-making cylinder 12. The swaying effect of the ice shavings inside the elliptical ice-making cylinder 12 is more obvious during rotation. This can effectively prevent the ice inside from freezing into a single, larger ice block, and ensure that the ice shavings formed inside the ice-making cylinder 12 are fine.
[0052] Working principle: Medical personnel add a certain amount of physiological saline to the inner ice-making cylinder 123, but not completely fill it. The inner ice-making cylinder 123 is then placed inside the outer ice-making cylinder 122, and the cylinder cover 121 is rotated on to seal and fix it. The entire ice-making cylinder 12 is then placed into the ice-making cylinder frame 132 within the cooling chamber 11 of the ice maker body 1. The cooling chamber 11 has a cold air vent 14 on its side, which is set at the same height as the ice-making cylinder frame 132 located on the turntable 13, allowing cold air to be sprayed onto the ice-making cylinder 12. Because the ice-making cylinder frame 132 is located on the rotatable part of the turntable 13, the turntable 13 is driven by the motor 131 and connecting rod 134 to rotate, causing the ice-making cylinder 12 to rotate within the cooling chamber 11 and receive the cold air. The cold air emitted from nozzle 14 provides uniform cooling. Simultaneously, the ice-making cylinder frame 132 features a uniformly arrayed grid, allowing the ice-making cylinder 12 to directly contact the cold air. Furthermore, the absence of gaps between the outer ice-making cylinder 122 and the inner ice-making cylinder 123 enhances the heat exchange efficiency between the saline solution and the cold air within the ice-making cylinder 12, lowering its temperature below freezing. This causes a phase change in water, from liquid to solid. As the temperature decreases, water molecules in the saline solution begin to slow their movement, gradually approaching the freezing point. Near the freezing point, the interaction forces between water molecules increase, and tiny ice crystal nuclei begin to form. When the temperature drops below freezing, these nuclei rapidly grow, forming ice crystals. The shearing force and agitation generated by rotating the ice-making cylinder 12 disrupt the larger ice crystals that have already formed. The saline solution rotates and flows within the cylinder, creating a stirring effect that helps break down existing ice crystals into smaller particles. When the ice-making cylinder 12 rotates in a certain direction, the ice crystals in the saline solution are distributed along with the rotation. However, prolonged rotation in one direction may cause ice crystals to aggregate in certain areas, forming larger ice crystal clumps. Changing the rotation direction can further disrupt the growth direction of the ice crystals, preventing the formation of larger ice blocks. Changing the rotation direction can also disrupt this aggregation trend, resulting in a more uniform distribution of ice crystals within the cylinder, preventing the formation of larger ice blocks. The shearing and frictional forces generated by the rotation and stirring have a significant impact on the formation and distribution of ice crystals. These forces help to break down the already formed ice crystal structures into smaller particles. Large ice crystals are broken down into smaller particles and distributed more evenly in the saline solution. Over time and with continuous rotation and stirring, the ice crystals in the saline solution gradually become smaller and more uniform. When the ice crystals are small enough and evenly distributed, a slush-like product is formed. Medical staff can then remove the ice container 12 and pour out the slush for use. In addition, rotation and stirring can promote the transfer and distribution of heat, making the temperature in the saline solution more uniform. This helps to avoid abnormal ice crystal growth caused by local overheating or overcooling. Furthermore, the lid 121 of the ice container 12, the parts that come into contact with the hands during use, and the ice container frame 132 are made of polymer materials to prevent injury from residual low temperatures when in contact with the hands.
