Description

Technical Field

[0001] This utility model relates to the field of sample storage technology, and in particular to a sample resuscitation device. Background Technology

[0002] To address the shortage of plasma for transfusions or the use of stem cells in transplantation, a common practice in healthcare facilities is to freeze individual plasma bags (usually between -20°C and -40°C) for later use. When plasma is needed, the necessary bags are thawed and heated to the required temperature, typically body temperature (35°C - 37°C).

[0003] There are several methods for thawing and heating plasma bags. The most common method is to place the plasma bag in a constant-temperature hot water bath and heat it for a sufficient time to reach the required temperature.

[0004] During this process, the plasma bag may rupture and release contaminated bath or become contaminated by bacteria in the bath solution. After resuscitation, the blood bag needs to undergo surface dehumidification and other procedures. Utility Model Content

Example 1

[0036] Reference Figures 1-3 This is the first embodiment of the present invention. This embodiment provides a sample resuscitation device, which includes a control mechanism 1 and a thawing assembly 2. The control mechanism 1 can control the thawing of samples in multiple sets of thawing assemblies 2.

[0037] Specifically, it includes a control mechanism 1 and a thawing component 2. The control mechanism 1 is connected to the thawing component 2. The thawing component 2 is configured as multiple groups. The control mechanism 1 can thaw the samples in multiple groups of thawing components 2.

[0038] Preferably, the thawing component 2 is set up in multiple groups, and each thawing component 2 can thaw the sample independently, avoiding cross-contamination and self-contamination, while also improving the thawing efficiency.

[0039] In summary, this invention prevents cross-contamination by placing each blood bag sample into a single thawing assembly 2 for resuscitation and thawing. Furthermore, the blood bags do not come into contact with water, thus preventing contamination of the blood bags themselves. This device eliminates the need for surface dehumidification of the resuscitated blood bag samples, significantly improving thawing efficiency. Example 2

[0040] Reference Figures 1-5 This is the second embodiment of the present invention. In the previous embodiment, the sample resuscitation device includes a control mechanism 1 and a thawing component 2. The control mechanism 1 can control the thawing of samples in multiple sets of thawing components 2.

[0041] Specifically, it includes a control mechanism 1 and a thawing component 2. The control mechanism 1 is connected to the thawing component 2. The thawing component 2 is configured as multiple groups. The control mechanism 1 can thaw the samples in multiple groups of thawing components 2.

[0042] Preferably, the thawing component 2 is set up in multiple groups, and each thawing component 2 can thaw the sample independently, avoiding cross-contamination and self-contamination, while also improving the thawing efficiency.

[0043] Furthermore, the control mechanism 1 includes a control pump 11, an upper channel 12, a lower channel 13, and a control valve 14; the control pump 11 is connected to the lower channel 13, the upper channel 12 and the lower channel 13 are respectively connected to the capsule 22, and the upper channel 12 is located above the lower channel 13; the control valve 14 is provided on the upper channel 12, and the control valve 14 is located on the outside of the capsule 22; the control pump 11 can control the positive or negative pressure of the capsule 22, and the control valve 14 can control the flow rate.

[0044] Preferably, the control pump 11 can rotate in both forward and reverse directions, and the control valve 14 is a one-way valve that can control the flow rate.

[0045] Furthermore, the control mechanism 1 also includes a water tank 15 and a water supply pipe 16; the water tank 15 is connected to the control pump 11 and the water supply pipe 16 respectively.

[0046] Preferably, the water tank 15 is connected to the control pump 11, which can supply and collect water; water can be added to the water tank 15 from the outside by setting up the water inlet pipe 16.

[0047] Furthermore, the thawing component 2 includes a housing 21, inside which a capsule 22 is disposed. The control mechanism 1 can control the capsule 22 to extend and retract to thaw or remove the sample.

[0048] Preferably, the capsule 22 can be contracted or expanded under the drive of the control mechanism 1, thereby completing the thawing of the sample and facilitating the loading and unloading operations.

[0049] Furthermore, a water bath chamber 23 is provided between the shell 21 and the capsule 22, and the control mechanism 1 uses the water bath chamber 23 to thaw the sample in the thawing assembly 2.

[0050] Preferably, water can be supplied to the water bath chamber 23 through the control mechanism 1, and the capsule 22 can be contracted or expanded by the positive or negative pressure of the water bath chamber 23, so that the capsule 22 fits or moves away from the blood sample.

[0051] Under positive pressure, the capsule 22 can fit the sample, and the blood sample can be thawed by the water flow. The water flow will not directly contact the blood sample, thus avoiding contamination of the blood sample itself.

[0052] Under negative pressure, the capsule component 22 will not completely adhere to the sample, making it convenient to remove and place the sample after thawing.

[0053] Preferably, by setting the thawing component 2 into multiple groups, the samples will not interfere with each other during thawing, thereby avoiding the situation of multiple samples contaminating each other.

[0054] Furthermore, the control mechanism 1 can control the positive or negative pressure of the water bath chamber 23.

[0055] Furthermore, the capsule component 22 includes a capsule 221, one end of which is provided with a placement opening 222. The diameter of the placement opening 222 gradually increases from the capsule 221, and the placement opening 222 is connected and sealed to the shell 21.

[0056] Furthermore, the water bath cavity 23 can enclose the capsule component 22.

[0057] Preferably, the capsule 22 can be wrapped by the water bath cavity 23, which can improve the thawing efficiency.

[0058] Thawing principle: The control pump 11 first draws water into the water tank. The water flows through the lower channel 13 into the water tank 15. The upper channel 12 is connected to the one-way control valve 14, which can only flow outward from the water bath chamber 23. Therefore, a negative pressure is formed in the water bath chamber 23 at this time, the capsule 22 expands, and the blood bag sample to be thawed and resuscitated is placed in it.

[0059] Then, the control pump 11 starts to feed water from the water tank into the water bath chamber 23. The upper channel 12 is connected to the one-way control valve 14 to adjust the water output. The water pressure in the water bath chamber 23 gradually increases, squeezing the capsule 22. The support 24 restricts the capsule 22 from twisting and deforming. The side wall of the capsule 22 is completely pressed against the blood bag sample, and the resuscitation and thawing are carried out through the temperature conduction of the water flow.

[0060] After thawing, the control pump 11 pumps water back into the water tank, the water bath chamber 23 is under negative pressure, the capsule 22 expands, and the revived blood bag sample is taken out.

[0061] Furthermore, the defrosting component 2 also includes a support member 24; the support member 24 can support and limit the capsule component 22.

[0062] Preferably, the expansion capsule 22 can be limited and fixed by the support member 24 to prevent the capsule 22 from twisting and deforming.

[0063] Furthermore, the support member 24 includes a support plate 241, on which multiple sets of through holes 242 are provided, and the support plate 241 can support and limit the capsule member 22.

[0064] By opening multiple sets of through holes 242 on the support plate 241, water flow can be facilitated.

[0065] Furthermore, the support member 24 and the housing 21 are detachably connected.

[0066] Preferably, by making the support 24 and the housing 21 detachably connected, they can be quickly replaced, thus adapting to different types of samples.

[0067] Furthermore, the defrosting component 2 is also equipped with a display control mechanism 3, which can control the water temperature inside the defrosting component 2.

[0068] Preferably, the display control mechanism 3 can display the status of the internal sample in real time, and can issue corresponding commands to control the water temperature, control the operation of the entire equipment, etc.

[0069] In summary, this invention prevents cross-contamination by placing each blood bag sample into a single encapsulated capsule for thawing, and the blood bags themselves are protected from contamination as they do not come into contact with the water flow. When the control pump draws water from the tank into the water bath chamber through the lower channel, the control valve on the upper channel can adjust the flow rate as needed, creating positive pressure in the water bath chamber. This compresses the capsule, ensuring it fits tightly against the blood bag sample inside, facilitating better thawing and warming. When the control pump, connected to the lower channel, draws water from the water bath chamber into the tank, the presence of the control valve on the upper channel creates negative pressure in the water bath chamber, causing the capsule to expand and allowing the blood bag sample to enter or be removed smoothly. The support plate is fixedly connected to the capsule, ensuring it remains fully expanded and preventing it from deforming or detaching from the water bath chamber due to water pressure. Multiple through holes on the fixed plate ensure normal water flow. The capsule and support plate are detachably connected to the equipment and can be directly removed from within the equipment for easy and quick replacement.
