Description

TECHNICAL FIELD

[0001] The utility model relates to the field of life science technology, especially a kind of storage liquid injection system. BACKGROUND

[0002] For life science instruments, such as cell culture equipment, during cell medium replacement or subculture, at least 2ml of culture medium, trypsin protein solution, and even more than 15ml of culture medium may need to be added within 10s, and the liquid is directly delivered from the reagent storage refrigerator, so the heating device needs to directly heat the liquid from 4-8℃ to 37℃ within 10s or less. In the prior art, part of the liquid delivery pipeline of the cell culture equipment adopts a metal pipeline, and during heating, the liquid is heated by directly heating the metal pipeline. Although the liquid is directly heated by the metal pipeline, it can meet the requirement of instantaneously heating the liquid from 4-8℃ to 37℃, but since the cell culture equipment has strict cleanliness requirements for the pipeline, the liquid directly heated by the metal pipeline may have the risk of not being cleaned properly. And every time the reagent is replaced or the culture cell type is changed, the metal body contacted by the individual reagent needs to be disinfected separately, and when the connection is reconnected, the hose connected to the metal body needs to be cut and spliced multiple times, which is time-consuming and labor-intensive. If the metal pipeline is replaced by a disposable plastic pipeline, although the cleanliness of the equipment can be solved, the heating efficiency is low, and this method cannot heat the liquid from 4-8℃ to 37℃ during liquid flow.

It can be understood that the specific embodiments described herein are merely intended to explain the utility model, and not to limit the utility model. In addition, it should be noted that, for the sake of description, only the parts related to the utility model are shown in the drawings, not all the structures.

[0028] In the description of the utility model, unless otherwise explicitly specified and limited, the terms "connected", "connected", "fixed" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements or the interaction relationship of two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0029] In the utility model, unless otherwise explicitly specified and limited, the first feature "on" or "below" the second feature can include that the first and second features are in direct contact, or the first and second features are not in direct contact but are in contact through another feature between them. Moreover, the first feature "on", "above" and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature "below", "below" and "below" the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.

[0030] In the description of the embodiment, the terms "up", "down", "right", etc. orientation or position relationship is based on the orientation or position relationship shown in the drawings, only for the convenience of description and simplification of operation, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second" are only used to distinguish in the description, and have no special meaning.

[0031] The utility model discloses a kind of storage liquid injection systems, refer to Figures 1 to 4As shown, the storage and injection system comprises a reagent storage module 100, an injection module 200, a heating module 400, a power pump 500 and an integrated consumable 300, the reagent storage module 100 is used for storing a reagent container 800, the injection module 200 is used for injection, the integrated consumable 300 comprises a connecting pipeline 320 and a heating adapter 310, the connecting pipeline 320 is used for connecting the reagent container 800 and the injection module 200, the heating adapter 310 has a liquid cavity 321 in communication with the connecting pipeline 320, the heating module 400 is detachably connected with the heating adapter 310 and is arranged around the liquid cavity 321 to heat the liquid in the liquid cavity 321, and the power pump 500 is installed on the connecting pipeline 320 and is used for driving the liquid in the reagent container 800 to flow to the injection module 200 through the liquid cavity 321.

[0032] The storage and injection system further comprises a control mechanism which can be a centralized or distributed controller, for example, the controller can be a single microcontroller or can be composed of multiple microcontrollers distributedly, and a control program can be run in the microcontroller to control the working of the heating module 400 and the power pump 500. It can be understood that, in the actual working process, when the control mechanism issues an injection instruction, the power pump 500 is started to draw the liquid reagent out of the reagent container 800, and the liquid reagent is heated by the heating module 400 again when passing through the liquid cavity 321. Since the heating module 400 is arranged around the liquid cavity 321, the contact area of the liquid reagent with the heating module 400 is large, and the heating speed is fast. When the liquid reagent flows out of the liquid cavity 321, it has reached the specified temperature to meet the injection requirement. At the same time, since the integrated consumable 300 comprises the connecting pipeline 320 and the heating adapter 310, when the consumable needs to be replaced, the heating adapter 310 is first detached from the heating module 400, then the connecting pipeline 320 is detached from the injection module 200 and the power pump 500, and the entire integrated consumable 300 can be replaced, which not only facilitates the operator to replace the consumable and improves the injection efficiency, but also meets the cleanliness requirement of cell culture.

[0033] It needs to be supplemented that, in the embodiment of the utility model, the reagent container 800 stored in the reagent storage module 100 can be a special bottle or a bag, and the reagent container 800 can accommodate a capacity of not less than several milliliters, such as 500ml or 1000ml. The shape, material and capacity of the reagent container 800 can be selected according to the injection parameters. In addition, the connecting pipeline 320 can be a silica gel pipe or a plastic pipe. In order to facilitate the connection with the injection module 200 and the power pump 500, the connecting end of the connecting pipeline 320 can be additionally provided with a connecting joint and the like structure to facilitate replacement.

[0034] Optionally, the heating module 400 is wrapped around the liquid cavity 321 to heat the liquid in the liquid cavity 321, and the heating module 400 wrapped around the liquid cavity 321 can sufficiently heat the liquid in the liquid cavity 321, thereby improving the heating efficiency.

[0035] Reference Figure 1 As shown, the reagent storage module 100 includes a storage shell 110 for storing the reagent container 800 and a refrigeration assembly 120 installed on the storage shell 110 and used to control the temperature inside the storage shell 110. First of all, it needs to be pointed out that the liquid reagent of the prior art cell culture equipment is taken out from the refrigerator when it is used on the same day, so it does not meet the automation requirements of the equipment for a long time without being attended, which requires additional labor costs to operate and maintain the equipment for high-throughput automated equipment. In the present embodiment, the reagent storage module 100 includes a storage shell 110 and a refrigeration assembly 120, and the refrigeration assembly 120 can control the temperature inside the storage shell 110, so that the reagent container 800 inside the storage shell 110 is kept in a specified temperature environment, so that the reagent container 800 does not need to be taken out from the refrigerator when it is used, but only needs to be stored in the storage shell 110 in advance, and the power pump 500 can be started directly when it is used, that is, the length of time of the equipment without being attended is increased by adding the reagent storage module 100, which is beneficial to improve the user experience. Specifically, the reagent storage module 100 of the present embodiment can provide low-temperature storage of 0-12℃ for reagents. The inner cavity of the storage shell 110 is a quadrilateral, and the refrigeration assembly 120 is installed on the side wall of the storage shell 110.

[0036] Optionally, the refrigeration assembly 120 includes a semiconductor refrigeration device and a cooling fan, and the cold end of the semiconductor refrigeration device is arranged towards the inside of the storage shell 110, and the cooling fan is arranged corresponding to the cold end. It can be understood that the semiconductor refrigeration device is used for refrigeration, and the cooling fan is arranged inside the storage shell 110, which uniformly spreads the cold energy generated by the cold end of the semiconductor refrigeration device to the entire storage shell 110, and a temperature sensor is arranged at the cold end of the semiconductor refrigeration device for monitoring the actual temperature of the cold end, and the temperature inside the storage shell 110 is stored in real time by PID, so as to ensure that the temperature of the reagent in the storage shell 110 will not be lower than 2℃, and at the same time, it is kept at a stable value between 4℃-8℃, which prevents the problem of reagent freezing. Of course, in other embodiments of the present application, the structure of the refrigeration assembly 120 can also select other structures such as the compression cooling system in the prior art according to actual needs, and is not limited to the above description.

[0037] Optionally, the power pump 500 needs to have the feature of adjustable output flow rate, which can be a peristaltic pump directly replacing the pipeline, or an injection pump composed of a driver and a disposable syringe. In addition, in the liquid flow direction, the power pump 500 can be located upstream of the heating module 400, or downstream of the heating module 400, and the number can be one or more. When the power pump 500 is multiple, at least one power pump 500 can be arranged upstream and downstream of the heating module 400.

[0038] Optionally, the delivery flow rate of the power pump 500 is less than 500ml / min. Of course, in other embodiments of the present application, the delivery flow rate of the power pump 500 can be set according to the liquid injection parameters of the liquid injection module 200, and is not limited to the above.

[0039] Optionally, the volume of the liquid cavity 321 is not more than 20ml. If the volume of the liquid cavity 321 is too large, the liquid flow rate will be reduced, which is not conducive to improving the liquid injection efficiency. By controlling the volume of the liquid cavity 321 to be less than 20ml, the liquid flow rate can be ensured while the heating efficiency can be guaranteed. Further optionally, the volume of the liquid cavity 321 is 500ul-15ml; in some alternative embodiments, the volume of the liquid cavity 321 is 2ml-5ml. Of course, the size of the volume of the liquid cavity 321 can be selected according to actual needs, and is not limited to the above.

[0040] Reference Figure 4 As shown, the heating module 400 includes two rotationally connected heating units 410, and the integrated consumables 300 are clamped between the two heating units 410. It can be understood that when a new liquid reagent needs to be replaced, only the connecting pipeline 320 needs to be inserted on the bottle cap of the reagent container 800, and the pump head of the power pump 500 is opened to install the connecting pipeline 320 to the specified position, while one of the heating units 410 is rotated, the heating adapter 310 is hung on the other heating unit 410, and then the previously rotated heating unit 410 is fixed back to the original position, ensuring that the heating elements 413 of the two heating units 410 can clamp the heating adapter 310, and the head of the connecting pipeline 320 is connected with the liquid injection module 200, that is, the entire replacement process can be completed. Therefore, the replacement operation is very convenient, which improves the user experience.

[0041] Reference Figure 4As shown, the heating unit 410 comprises a heating shell 411, a heat preservation member 412 and a heating member 413. The heating shell 411 is open towards the heating adapter 310. The heat preservation member 412 is installed on the heating shell 411. The heating member 413 is installed on the heating shell 411. One side of the heating member 413 abuts against the heat preservation member 412, and the other side abuts against the heating adapter 310. It can be understood that the heat preservation member 412 can ensure that as much heat generated by the heating member 413 as possible is transmitted to the heating adapter 310, thereby improving the heating effect and the heating efficiency of the heating member 413.

[0042] Optionally, the heating member 413 can be a PI heating film, a ceramic heating sheet or other heat sources. The heating member 413 can also be provided with a temperature probe and a temperature protection switch. In actual work, the temperature of the heating member 413 can be detected by the temperature probe. The temperature protection switch can disconnect the power supply circuit of the heating member 413 when the heating member 413 is overheated, so that the maximum temperature of the heated liquid does not exceed the preset temperature (usually 37℃, but it can also be adjusted according to the liquid injection parameters). The PID closed-loop control formed by the temperature probe, the temperature protection switch and the heating member 413 not only improves the temperature control accuracy of the heating unit 410, but also ensures the working reliability of the heating unit 410 and reduces the failure rate.

[0043] Optionally, the heating shells 411 of the two heating units 410 are rotatably connected by a hinge 420. When the heating adapter 310 is replaced, the hinge 420 is only opened to change the two heating units 410 from the overlapping state to the parallel state, so that the replacement can be realized. Further optionally, the two leaves of the hinge 420 are locked by a connecting screw. It can be understood that when the heating adapter 310 is replaced, the heating adapter 310 is placed on one heating unit 410, and then the other heating unit 410 is rotated to abut against the heating adapter 310. Then the two leaves are locked by the connecting screw, so that the phenomenon that the two heating units 410 are accidentally opened and the heating adapter 310 falls off during the liquid injection process can be avoided. Of course, in other embodiments of the present application, the heating shells 411 of the two heating units 410 can also be connected by other rotating connection modes, for example, an elastic body capable of folding and unfolding can be used to connect the heating shells 411 of the two heating units 410.

[0044] In an alternative embodiment, the heating module 400 comprises a rotatably connected heating unit 410 and a heat conduction unit. The integrated consumable 300 is clamped between the heating unit 410 and the heat conduction unit. The heat conduction unit is a metal body with good heat conduction performance.

[0045] Reference Figure 2As shown, the heating adapter 310 also has a liquid inlet and outlet in communication with the liquid cavity 321, and the liquid inlet and outlet has an expanded state and a contracted state. It can be understood that when the power pump 500 is started, the liquid passes through the liquid inlet and outlet to expand the liquid inlet and outlet, and enters the liquid cavity 321 to facilitate the flow of the liquid. When there is no liquid flow, the liquid inlet and outlet is in a contracted state, which can prevent gas from entering the liquid cavity 321, thereby reducing the probability of liquid injection bubbles and improving the quality of liquid injection. It should be noted that the position of the liquid inlet and outlet can be adjusted according to actual needs. In the embodiment, the liquid inlet and outlet are two, one of which is a liquid inlet and the other is a liquid outlet, and are respectively located on both sides of the liquid cavity 321. The liquid inlet is located below, and the liquid outlet is located above. In actual work process, the liquid can fill the liquid cavity 321 from bottom to top, thereby improving the heating efficiency.

[0046] In an alternative embodiment, the liquid inlet and outlet are one, which simultaneously acts as a liquid inlet and a liquid outlet, and the liquid cavity 321 also has a gas permeable end. A switch valve is installed at the liquid inlet and outlet. In actual work process, the filling and emptying of the liquid in the liquid cavity 321 can also be achieved by controlling the opening and closing state of the switch valve.

[0047] Optionally, as shown in Figure 3 The heating adapter 310 is packaged into a bag by two films 322. The bag can have the shape of the liquid cavity 321, as shown in Figure 2 The shape of the liquid cavity 321 is a rhombus structure, and other shapes can also be selected according to actual needs. The bag formed by the two films 322 as the heating adapter 310 can simplify the manufacturing of the heating adapter 310 and reduce the manufacturing cost of the integrated consumable 300. Further, the spacing between the two films 322 is 0.1mm when the heating adapter 310 is filled with liquid.

[0048] Optionally, the inner wall of the liquid cavity 321 is provided with a plurality of protrusions, and the plurality of protrusions are used to divide the liquid cavity 321 into a plurality of liquid flow channels. In this way, the flow path of the liquid in the liquid cavity 321 can be increased, the contact time of the liquid with the heating module 400 can be increased, and thus the liquid flowing through the liquid cavity 321 can be heated to a specified temperature.

[0049] It should be noted that in other embodiments of the present application, the heating adapter 310 can also be a cylindrical pipe body, a disposable centrifuge tube or other structures. The heating adapter 310 can be a plastic product or a metal product, and the specific parameters of the heating adapter 310 can be adjusted according to the liquid injection parameters.

[0050] Reference Figure 1As shown, the storage liquid injection system further comprises a detection module 600 installed between the heating module 400 and the liquid injection module 200, which is used to detect whether liquid flows to the liquid injection module 200 and whether there is a bubble in the liquid. It can be understood that the added detection module 600 can detect whether liquid flows to the liquid injection module 200 and whether there is a bubble in the liquid, thereby realizing monitoring of the liquid injection process and stopping liquid injection in time when there is a liquid injection bubble. In order to facilitate detection, the detection module 600 can be a non-contact sensor.

[0051] Reference Figure 1 As shown, the storage liquid injection system further comprises a control valve 700 installed between the heating module 400 and the detection module 600. Optionally, the control valve 700 can be a conventional two-position three-way valve or a pinch valve facilitating replacement of the connecting pipeline 320.

[0052] The working mode of the storage liquid injection system of the utility model can be as follows:

[0053] The first kind: when the system receives a liquid injection instruction, the control valve 700 is opened, and then the power pump 500 is started (the starting mode can be that a driver drives the peristaltic pump to rotate), at this time, the reagent is extracted from the reagent container 800 and flows to the liquid cavity 321 through the connecting pipeline 320, and the liquid in the liquid cavity 321 is heated from 4 DEG C to 37 DEG C, and the heated liquid is detected by the detection module 600 and then flows out from the liquid injection module 200 to realize liquid injection. After the liquid injection is completed, the power pump 500 needs to suck the liquid remaining in the heating adapter 310 back to the reagent container 800, so as to prevent the existence of liquid with a temperature greater than 37 DEG C in the connecting pipeline 320.

[0054] The second kind: before the system receives a liquid injection instruction, a preheating instruction of the liquid reagent can be executed, at this time, the control valve 700 is closed, and the heating unit 410 is opened, so as to actually preheat the liquid filled in the heating adapter 310, and the preheating temperature is 37 DEG C, when receiving the liquid injection instruction, the control valve 700 is opened, and then the power pump 500 is started (the starting mode can be that a driver drives the peristaltic pump to rotate), at this time, the liquid reagent is extracted from the reagent container 800 and enters the heating adapter 310 through the connecting pipeline 320, and the liquid reagent with a temperature of 37 DEG C in the heating adapter 310 is detected by the detection module 600 and then flows out from the liquid injection module 200 to realize liquid injection.

[0055] The storage liquid injection system of the utility model has the following advantages:

[0056] Firstly, the air cooling mode is used for cold quantity delivery to ensure the temperature uniformity in the storage shell 110, and the semiconductor refrigeration element is matched with the intelligent control algorithm to ensure the stability of the storage temperature, so that the liquid reagent can be stored at a stable and suitable temperature.

[0057] Secondly, the special heating adapter 310 is used to increase the contact area of the liquid flowing through the heating module 400, improve the heat exchange efficiency of the liquid and the heating module 400, and achieve the instant heating effect of the liquid from 4 DEG C to 37 DEG C.

[0058] Thirdly, the complete integrated consumable 300 is used to realize the overall replacement of the consumable when the liquid reagent is replaced, improve the work efficiency, and provide a guarantee for the cleanliness of the cell culture environment.
