Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a slurry melting machine. Background Technology

[0002] Plasma thawing machines are crucial equipment in blood transfusion departments. Their primary function is to rapidly thaw frozen plasma and cryoprecipitates from -20°C to 37°C while maintaining the bioactivity of blood products. This is used to treat patients with massive hemorrhage and coagulation disorders. The performance of the plasma thawing machine directly affects the quality of blood products and the therapeutic effect. Based on differences in heat transfer media and thawing principles, the mainstream equipment is mainly divided into three types: water bath, air bath, and immersion thawing. Different types vary in thawing efficiency, biosafety, and ease of operation.

[0003] Water bath thawing machines are the most traditional and common type of thawing equipment. They primarily involve immersing frozen blood plasma and other blood products directly into a constant-temperature water bath, utilizing water's high specific heat capacity to achieve rapid heat exchange between the water and the frozen blood products. Advantages include high thawing efficiency, simple equipment structure, and low purchase cost. Disadvantages are also significant, mainly: 1. Blood bags are in direct contact with circulating water, and the blood bag labels are prone to detaching after immersion, posing a risk of incorrect blood bag information identification; 2. If blood bags are damaged, the circulating water will be contaminated, and contaminated water may seep into other blood bags, increasing the incidence of adverse transfusion reactions. 3. After the water bath, a large amount of water stains remain on the surface of the blood bags, contaminating the operating environment; 4. Through recycling, the water in the tank evaporates or becomes contaminated, requiring frequent water changes. Furthermore, the incubation mesh in the tank obstructs the thorough disinfection of the water bath, and the warm water environment is prone to bacterial growth, posing a biosafety risk; 5. The equipment requires connection to a water inlet faucet and a drain outlet, making the installation location inflexible. It also requires piping and water valve installation, posing a risk of water and electrical leakage in the laboratory.

[0004] Air-bath thawing machines utilize the principle of air convection heating, achieving dry thawing through internal hot air circulation. Advantages include no risk of aqueous contamination, dry blood bag surfaces after thawing, and no need for regular water changes. Disadvantages include a thermodynamic efficiency bottleneck; low air heat transfer efficiency results in longer thawing times; and a significant temperature gradient in the hot air leads to poor thawing uniformity, potentially causing localized overheating near the air vent, leading to protein denaturation, while areas further away from the vent remain underthawed.

[0005] The water-sealed plasma melting machine employs a dual mechanism of hydrothermal conduction and physical isolation. A flexible water-sealed membrane bag separates the heated water from the blood bag, achieving plasma melting efficiency close to that of a water bath system while eliminating water-based contamination. Advantages include high plasma melting efficiency, prevention of direct contact between wastewater and plasma, quiet operation, and flexible installation location. Disadvantages include a limited number of blood bags that can be melted at once, insufficient mechanical strength of the water-sealed membrane bag leading to a risk of rupture. If ruptured, the entire water-sealed membrane bag and internal water inlet / outlet pipes must be replaced, resulting in cumbersome operation and high material costs.

[0006] Given the performance characteristics and shortcomings of the above three types of plasma thawing machines, how to provide a plasma thawing machine that can increase the capacity of disposable thawing blood bags and reduce consumable costs is an urgent problem to be solved.

[0042] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present utility model, and does not imply that every embodiment of the present utility model must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0043] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0044] In some embodiments, such as Figures 1-2 As shown, this utility model proposes a plasma melting machine that can increase the capacity of disposable thawing blood bags and reduce consumable costs, comprising:

[0045] The cover plate 10 and the main body 20 are fitted together. The main body 20 is provided with a plurality of receiving slots 201 facing the top of the cover plate 10. Each receiving slot 201 can be detachably connected to a sealed storage device 30 for placing blood bags.

[0046] The circulation pump 40 has its outlet side connected to the inlet of all the receiving tanks 201 or the inlet of all the sealed storage devices 30 via an inlet pipe 203, and its inlet side is connected to the outlet of all the receiving tanks 201 or the outlet of all the sealed storage devices 30 via an outlet pipe 202.

[0047] A heating device 50 is installed on the water inlet pipe 203 near the outlet side of the circulating pump 40.

[0048] It should be noted that the sealed storage device 30 proposed in this embodiment is preferably a sealed bladder-like structure made of flexible material (such as plastic or composite film), or a sealed bag-like structure made of heating water-proof membrane or other materials with elastic deformation and thermal conductivity, and is not limited here. Furthermore, in this embodiment, the receiving grooves 201 on the top of the cover plate 10 are arranged in a rectangular or square array, and the shape of the receiving grooves 201 is cuboid or spherical. The slurry melting machine proposed in this embodiment also includes a main control unit (not shown, the same throughout), which is electrically connected to the circulating pump 40 and the heating device 50 respectively. The connection between the receiving groove 201 and the sealed storage device 30 inside is a detachable connection such as a snap-fit ​​or bolt connection.

[0049] In this embodiment, when using the thawing machine, first open the cover plate 10 relative to the main body 20, then correctly place frozen blood bags (including plasma bags, red blood cell bags, or cryoprecipitate clotting factor bags) or other bagged items that need to be thawed into the sealed storage device 30, and then close the cover plate 10 relative to the main body 20; then the main control unit starts the circulation pump 40 and the heating device 50. At this time, the circulation pump 40 draws the circulating liquid (in this embodiment, water is used as an example, but of course, the circulating liquid can also be other cooling media) in the outlet pipe 202 to the inlet pipe 203, and at the same time, the heating device 50 heats the circulating liquid that passes through it. The heated circulating liquid then flows into the receiving tank 201 (e.g., Figure 5 As shown, the inner wall of the sealed storage device 30 adaptively covers the blood bag through fluid pressure, allowing the heated circulating liquid to exchange heat with the frozen blood bag inside the sealed storage device 30 to thaw the frozen blood bag. The circulating liquid after heat exchange flows out through the drain pipe 209 and then into the outlet pipe 202, thus forming a circulation path. Due to the circulation of the circulating liquid, the frozen blood bag will shake along the flow direction of the circulating liquid, which can further improve the thawing efficiency. After the frozen blood bag in the sealed storage device 30 has thawed, the user can take it out and then put in the next frozen blood bag to be thawed or turn off the thawing machine.

[0050] Therefore, this utility model can provide multiple receiving slots 201 on the main body 20 as needed. Each receiving slot 201 has a detachable (clamped or bolted) sealed storage device 30 that can individually wrap a blood bag, which improves the thawing efficiency and allows multiple blood bags to be thawed at one time, thus avoiding the problem of small capacity. Moreover, the sealed storage device 30 can be disassembled independently, with a simple structure, making it convenient to replace or maintain the sealed storage device 30 and reducing the cost of consumables.

[0051] Furthermore, the sealed storage device 30 can effectively isolate the blood bag and circulating fluid, thereby blocking direct contact between the circulating fluid and the blood bag and preventing water-based contamination. If the sealed storage device 30 is damaged and leaks, compared with the water-tight slurry melting machine in the prior art, this utility model only needs to replace the new sealed storage device 30, without replacing the pipes inside the slurry melting machine, thereby reducing the cost of consumables.

[0052] Or, such as Figure 6 As shown, the sealed storage device 30 proposed in this embodiment has a double-wall structure, with an annular sealed cavity formed between its inner wall and outer wall. The water inlet of each annular sealed cavity is connected to the water inlet pipe 203 through the water supply pipe 207, and the water outlet of each annular sealed cavity is connected to the water outlet pipe 202 through the drainage pipe 209.

[0053] In this way, the blood bag is correctly placed into the cavity formed by the inner wall of the sealed storage device 30. Then, the heated circulating liquid enters the annular sealed cavity and fills it. This allows the inner wall to adaptively cover or clamp the blood bag through fluid pressure, thereby achieving heat conduction, improving heating efficiency, and improving plasma melting efficiency.

[0054] The heating device 50 includes, but is not limited to, the following two structures:

[0055] Firstly, the heating device 50 is preferably a semiconductor heating tube, which is located in the water inlet pipe 203 near the water outlet side of the circulating pump 40. The circulating liquid is heated by the semiconductor heating tube and then flows into the receiving tank 201.

[0056] Secondly, such as Figure 3 As shown, the heating device 50 includes a preheating chamber 501, the inlet of which is connected to the outlet of the circulating pump 40, and the outlet of which is connected to the inlet pipe 203; and a heater 502 is installed inside the preheating chamber 501. Thus, the circulating pump 40 draws the circulating liquid from the outlet pipe 202 into the preheating chamber 501, and then the heater 502 heats the circulating liquid in the preheating chamber 501. The heated circulating liquid then flows into the receiving tank 201 through the inlet pipe 203.

[0057] In other embodiments (not shown in the figures), a swing assembly is provided inside the receiving groove 201 corresponding to the sealed storage device 30. The swing assembly is electrically connected to the main control unit. In this way, the main control unit can control the swing assembly to perform periodic reciprocating motion (such as pendulum or eccentric wheel drive), thereby applying a dynamic force to the sealed storage device 30, so that the sealed storage device 30 shakes as a whole with the swing assembly in the receiving groove 201, thereby further improving the thawing efficiency of the frozen blood bags placed in the sealed storage device 30.

[0058] In some embodiments, such as Figure 2 As shown, the inlet of the circulating pump 40 is connected to the outlet of the liquid storage device 60, and the inlet of the liquid storage device 60 is connected to the outlet pipe 202.

[0059] In this way, the liquid storage device 60 can balance the instantaneous flow fluctuations in the piping system within the grouting machine, preventing sudden pressure changes caused by direct suction from the circulating pump 40. When the flow rate of the circulating liquid flowing out of the receiving tank 201 suddenly increases, the liquid storage device 60 can temporarily store the excess water; when the flow rate of the circulating liquid flowing out of the receiving tank 201 is insufficient, the liquid storage device 60 replenishes the water supply, ensuring a stable flow rate on the inlet side of the circulating pump 40. Furthermore, the liquid storage device 60 also has a buffering function, absorbing water hammer pressure fluctuations in the piping system caused by rapid valve opening and closing or the start and stop of the circulating pump 40, protecting the piping system and the grouting machine from impact damage.

[0060] In some embodiments, to ensure precise control over the flow of circulating liquid into or out of the receiving tank 201, such as Figure 2 As shown, the circulation pump 40 is provided with a first solenoid valve 204 at the outlet side, and the liquid storage device 60 is provided with a second solenoid valve 601 at the inlet.

[0061] An auxiliary pipe 205 is provided between the water inlet end of the first solenoid valve 204 and the water inlet end of the second solenoid valve 601, and a third solenoid valve 206 is provided inside the auxiliary pipe 205.

[0062] In this way, when the slurry melting machine is shut down, the main control unit closes the first solenoid valve 204 and the second solenoid valve 601, starts the third solenoid valve 206, and then reverses the circulation pump 40 to collect the circulating liquid in the receiving tank 201 to the outlet pipe 202, and then flows to the auxiliary pipe 205 and the circulation pump 40 in sequence before flowing into the liquid storage device 60, so that the remaining circulating liquid in the receiving tank 201 is pumped into the liquid storage device 60 by the circulation pump 40.

[0063] In order to ensure precise control of the flow of circulating liquid into the container 201 containing blood bags, the inlet of each container 201 is connected to the inlet pipe 203 through a water supply pipe 207, and a fourth solenoid valve 208 is provided in each water supply pipe 207.

[0064] It should be noted that the main control unit proposed in this embodiment is electrically connected to the first solenoid valve 204, the second solenoid valve 601, the third solenoid valve 206 and the fourth solenoid valve 208 respectively.

[0065] In some embodiments, to ensure rapid water filling and drainage by gravity, and to allow for the sedimentation of impurities in the circulating liquid, preventing particulate matter from entering the impeller of the circulating pump 40 and causing wear, such as... Figure 1 As shown, the liquid storage device 60 is located at the bottom of the main body 20 away from the cover plate 10.

[0066] In some embodiments, to more precisely activate the fourth solenoid valve 208 corresponding to the receiving groove 201, such as... Figure 2 As shown, each of the sealed storage devices 30 is equipped with a detection device 70, which is used to detect whether there is a blood bag occupying space in the sealed storage device 30.

[0067] To ensure precise control of the blood bags to reach the optimal thawing temperature, each of the sealed storage devices 30 is equipped with a temperature measuring device 80, which is used to detect temperature changes inside the blood bags.

[0068] It should be noted that the main control unit proposed in this embodiment is electrically connected to the detection device 70 and the temperature measuring device 80, respectively. The detection device 70 proposed in this embodiment includes a photoelectric sensor or a pressure sensor. The photoelectric sensor detects the presence of blood bags within the sealed storage device 30, blocking the light path trigger signal when a blood bag occupies the position. The pressure sensor is installed at the bottom of the sealed storage device 30 and determines whether a blood bag occupies the position based on weight changes. The temperature measuring device 80 proposed in this embodiment is preferably a thermocouple or an infrared thermometer.

[0069] In some embodiments, such as Figure 1 As shown, the outer side wall of the main body 20 is detachably provided with a maintenance plate 90 corresponding to the circulating pump 40 and the heating device 50, and the maintenance plate 90 is provided with a plurality of heat dissipation through holes 901.

[0070] In this way, when the grouting machine needs to be inspected and maintained, the inspection plate 90 can be removed to inspect and repair the internal components of the grouting machine; and the heat generated by the circulating pump 40 during operation can be exchanged with the outside air through the heat dissipation hole 901 to achieve the purpose of heat dissipation.

[0071] In some embodiments, such as Figure 4 As shown, an operation panel 100 is provided on any of the outer side walls of the thawing machine, excluding the inspection plate 90. The operation panel 100 allows users to set the thawing time and temperature independently, or input preset thawing time and temperature in advance. The operation panel 100 also has function buttons for self-circulation detection, start, stop, and emergency stop. Furthermore, the operation panel 100 can display information such as the real-time operating temperature of the heating device 50, the temperature inside the blood bag detected by the detection device 70, and the remaining thawing time.

[0072] Of course, in other embodiments, such as Figure 1 As shown, the liquid storage device 60 proposed in this embodiment can also be equipped with a water level detection component 602. This water level detection component 602 is used to detect whether the water level in the liquid storage device 60 has reached the warning value. If the water level in the liquid storage device 60 reaches the warning value, a warning pop-up window will appear on the operation panel 100 or a buzzer will sound to inform the user that the circulating liquid in the liquid storage device 60 is insufficient (e.g., due to evaporation, splashing, etc.). At this time, the user can open the water inlet provided on the liquid storage device 60 to replenish the circulating liquid in the liquid storage device 60 so that the slurry melting machine can operate normally. After replenishment, the user can seal the water inlet to prevent leakage. Of course, the liquid storage device 60 is also equipped with a drain outlet so that the user can use the water inlet and the drain outlet together to replace the circulating liquid in the slurry melting machine.

[0073] The usage process of the slurry melting machine proposed in this utility model is as follows:

[0074] The main control unit first turns on the main power supply to enable the grout melting machine to perform a self-circulation test. After the test is normal, the user can set the defrosting time and defrosting temperature on the operation panel 100 on the grout melting machine, or input the preset defrosting time and defrosting temperature in advance, and then the grout melting machine starts working.

[0075] The user first opens the cover 10 relative to the main body 20, then correctly places the corresponding number of frozen blood bags into the sealed storage device 30, and then closes the cover 10 relative to the main body 20. Then the main control unit starts the circulation pump 40, the heating device 50, the first solenoid valve 204, and the second solenoid valve 601, and closes the third solenoid valve 206. The main control unit uses the detection device 70 to detect whether there are blood bags occupying the corresponding sealed storage device 30. If there are, it starts the corresponding fourth solenoid valve 208. At this time, the circulation pump 40 draws the circulating liquid in the storage device 60 to the inlet pipe 203. Then the heating device 50 heats the circulating liquid to the set temperature and it flows into the container 201 containing the frozen blood bags for heat exchange to thaw the frozen blood bags. At the same time, the circulating liquid flowing into the container 201 will flow to the outlet pipe 202 and then flow into the storage device 60, forming a circulation path. Furthermore, once the set thawing time is reached, the main control unit closes the fourth solenoid valve 208 corresponding to each container 201 containing blood bags, so that the remaining circulating liquid in the container 201 is pumped into the storage device 60 by the circulation pump 40.

[0076] The main control unit monitors the temperature changes inside the blood bag in real time through the temperature measuring device 80. When the temperature inside the blood bag reaches the optimal thawing temperature, the plasma melting machine will issue an alarm (such as a buzzer and flashing or constant light) to notify the user to remove the thawed blood bag and then put in the next frozen blood bag to be thawed or turn off the plasma melting machine.

[0077] When the plasma melting machine is turned off and no further thawing of blood bags is planned, the main control unit shuts down the heating device 50, the first solenoid valve 204, the second solenoid valve 601, and the fourth solenoid valve 208, starts the third solenoid valve 206, and then controls the circulation pump 40 to reverse, collecting the circulating liquid in the receiving tank 201 into the outlet pipe 202, and then flowing into the storage device 60 after passing through the auxiliary pipe 205 and the circulation pump 40 in sequence. This allows the remaining circulating liquid in the receiving tank 201 to be pumped into the storage device 60 by the circulation pump 40.

[0078] The temperature measuring device 80 feeds back the temperature inside the corresponding blood bag to the main control unit. The main control unit then integrates the temperature values ​​inside all blood bags and dynamically adjusts the heating temperature of the heating device 50 to keep the temperature inside the blood bag within a reasonable range.

[0079] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments.
