Description

Technical Field

[0001] The present invention belongs to the technical field of plasma storage auxiliary equipment, and particularly relates to a dry thawing support component for plasma bags. Background Art

[0002] During the storage and use of plasma obtained by natural sedimentation or centrifugation within the whole blood storage period or validity period, it is necessary to quickly freeze it with the plasma bag to a temperature of -30°C to form frozen plasma. When in use, it needs to be placed in a constant temperature water bath at about 37°C and continuously shaken and melted until the plasma is completely melted. To ensure the high efficiency and rapidity of the above process, some special plasma thawing devices have emerged on the market, including the "Plasma Thawing Instrument and Automatic Control Method for Plasma Thawing" provided by the applicant, with a publication number of CN102258816B, etc. To facilitate use, the applicant also provided a "Dry Thawing Bag", with an application number of 202120670430.X, for the positioning and support of plasma bags during the actual thawing operation process. It can achieve batch thawing, improve the thawing efficiency, and effectively solve the problems that the blood bags lack an effective fixing method in the constant temperature water bath equipment and are prone to floating disorderly with the water flow during the current thawing process. However, during the long-term use and testing of the product, the applicant also found that the aforementioned structure would have some problems after long-term immersion in the water bath and shaking operation. One is that the fixing and locking strength of its isolation bag is insufficient, and with the accumulation of material heating and friction, etc., the connection relationship between the top limiting hole and the fixing card will undergo fatigue damage. The second is that the support plate frame part is mainly made of sheet metal structure, while the heat conduction bag is made of a soft material with an extremely small thickness. The part of the heat conduction bag clamped in the plate frame is easily damaged and torn after being clamped and long-term shaking. At the same time, the edges of the lower end surfaces around the plate frame may also cause cutting damage to the isolation bag after long-term work. The third is that although there is a support frame for supporting the frozen blood bag in the isolation bag, during the thawing process of the frozen blood bag, the blood bag becomes soft and sags near the isolation bag from both sides of the support frame. The solid-liquid mixture in the blood bag squeezes the blood bag, resulting in an increase in the pressure borne by the bottom of the isolation bag and the blood bag. After long-term shaking, the local friction and vibration are aggravated, and there is a risk of damage to the isolation bag or the blood bag. Summary of the Invention

[0037] The dry thawing support component of the plasma bag in this application is an upgraded improvement based on the applicant's early solution "A Dry Thawing Bag" with the application number 202120670430.X. At the same time, a supporting component for improving the water bath thawing effect is also provided to improve the product defect problems existing in the early solution, improve its performance, reduce the use cost, and further expand its performance.

[0038] The following will describe the present invention in detail with specific embodiments.

[0039] As Figure 1 , Figure 2 , Figure 3 As shown in [IDs], etc., it is the basic structure of a preferred embodiment of this application, which is used for thawing or insulating frozen plasma bags, and includes a main support component 1, a blood bag support component 2, and a cantilever hanging component 3;

[0040] The main support component is used to form an overall positioning support structure, determine the installation position and installation method of the plasma bag, and at the same time limit and position the plasma bag to prevent it from moving with the flowing water during the water bath oscillation. The traditional solution is to use a simple grid cage structure. This application follows the thermal insulation isolation bag structure in the early solution. Compared with the grid cage structure, the thermal insulation isolation bag can effectively prevent the warm water from washing off the labels on the surface of the plasma bag during the water bath process, prevent the plasma bag and the liquid in the water bath from being contaminated, and at the same time, as an indirect temperature medium, the thermal insulation isolation bag realizes a smooth temperature transition. In actual use, it is necessary to monitor the temperature of the plasma bag accurately in real time. Placing the temperature sensor in the isolation bag can also better measure the temperature of the plasma bag and prevent interference from the medium in the water bath. The main structure of the main support component 1 includes a positioning plate frame 10 and a supporting plate frame 11.

[0041] The positioning plate frame 10 is composed of a support plate surface 100 provided with a number of strip-shaped positioning holes 10a and fastening plate surfaces 101 provided on the front, rear, left, and right sides of the support plate surface and extending downward; the strip-shaped positioning holes 10a are arranged in parallel, and strip-shaped fastening holes 10b are respectively arranged on both sides of the strip-shaped positioning holes 10a; the supporting plate frame 11 includes strip-shaped plate surfaces 110 provided on the front edge and the lower sides of the left and right edges of the support plate surface 100, and the strip-shaped plate surfaces 110 extend vertically and are perpendicular to the support plate surface 100; the inner side wall surfaces 9a of the fastening plate surfaces 101 are respectively attached to the outer side wall surfaces 9b of the strip-shaped plate surfaces 110 to improve the stability of the plate frame;

[0042] As a conventional preferred setting, the strip-shaped positioning holes 10a are parallel to each other and the extending direction is close to or consistent with the flowing direction of the medium in the water bath, so that the constant temperature water flow can continuously and smoothly pass through the heat conduction isolation bag, and at the same time increase the heat transfer efficiency. The parallel and consistent setting method can also make the vibration and swing directions of the isolation heat conduction belts in the strip-shaped positioning holes remain the same or close, thereby avoiding mutual interference and collision.

[0043] like Figure 2 、 Figure 4 、 Figure 5 As shown, the blood bag support assembly 2 includes a heat-conducting isolation bag 20, an annular pressure plate 21, and a U-shaped rib plate 22; the blood bag support assembly is used to protect the plasma bag and isolate the plasma bag from the constant temperature medium in the water bath to prevent the plasma bag and the constant temperature medium from being contaminated (labels or accessories on the surface of the plasma bag may fall into the medium and contaminate the medium, and the medium may also contain impurities that contaminate the plasma bag).

[0044] The cross-sectional shape of the thermally conductive isolation bag 20 matches the strip-shaped positioning hole 10a and is open at the upper end. An annular limiting ring 200 is provided at the edge of the opening. The thermally conductive isolation bag 20 is inserted into the strip-shaped positioning hole 10a from top to bottom.

[0045] The annular pressure plate 21 includes an annular support plate surface 210 whose shape and size match the opening of the thermal insulation bag 20, and a clamping plate surface 211 formed by extending outward from the upper edge of the annular support plate surface 210 and then bending downward. The outer wall of the annular support plate surface 210 is in contact with the inner wall of the thermal insulation bag 20; the connection between the annular support plate surface 210 and the clamping plate surface 211 forms an arc-shaped limiting groove 212, and the annular pressure plate 21 is inserted into the thermal insulation bag 20. At the same time, the arc-shaped limiting groove 212 clamps the annular limiting ring 200 so that it presses against the upper surface of the support plate surface 100; the clamping plate surface 211 extends to the side away from the annular support plate surface 210 to form a barb structure 213. After the lower half of the clamping plate surface 211 and the barb structure 213 are inserted into the strip-shaped buckle hole 10b, the barb structure 213 is buckled on the lower end surface of the support plate surface 100;

[0046] In the old solution, the top of the thermal insulation bag is a traditional bag-packed structure, which is directly clamped between the annular pressure plate and the support plate surface during use. During the water bath process, the entire thawing support component will continue to vibrate, and the thermal insulation bag will also be impacted and pulled by the water flow in the water bath, resulting in long-term wear between the thermal insulation bag and the clamping structure. Problems such as tearing or holes are prone to occur. By setting it into an annular limit ring and cooperating with a shape-changing limit groove structure, the clamping surface is not completely in contact, but forms an elastic gasket structure. On the one hand, it greatly increases the contact area and avoids local force concentration. On the other hand, the tension received by the thermal insulation bag is transmitted to the thicker annular limit ring part, thereby improving the tear and damage resistance. In actual testing, it was found that with this improvement, the service life / number of times of traditional EVA material increased by 70~100%, which is an obvious effect. At the same time, in addition to being directly formed by the outer edge of the thermal insulation bag, the structure of the annular limit ring can also be embedded with an elastic elastic band inside it, so that it can automatically shrink and wrap around the clamping annular support plate surface 210, effectively improving the connection strength.

[0047] Among them, the U-shaped rib plate 22 is inserted into the thermal isolation bag 20, and its bottom is suspended above the bottom of the thermal isolation bag 20. The distance between the bottom of the U-shaped rib plate 22 and the bottom of the thermal isolation bag 20 is 0.5~2cm; the top ends of the two vertical arms of the U-shaped rib plate 22 extend outward to form a hook structure 220 and are buckled onto the annular pressure plate 21. Based on traditional design thinking and solutions, the height of the thermal insulation bag and the rib plate are generally designed to be consistent. However, after long-term use, it was found that a small number of plasma bags, after being frozen and softened, drooped to both sides of the rib plate. Part of the solid-liquid mixture would remain at the bottom of the plasma bag, causing it to squeeze against the thermal insulation bag, resulting in excessive wear or impact during the oscillation process. This led to accidental damage to the thermal insulation bag or plasma bag. Through testing, it was found that only the U-shaped rib plate needed to be lifted a certain distance so that the bottom of the plasma bag could not directly contact the thermal insulation bag, which could effectively prevent accidental wear and damage during the solid-liquid mixing stage. In addition to support and positioning, another function of the U-shaped rib plate is to provide support and protection when the incoming flow direction in the water bath brings impact to the side of the thermal insulation bag.

[0048] The traditional oscillation process generally uses a hanging or a robotic arm to connect the oscillation drive device. However, due to the unreasonable speed control of the driving arm of the oscillation drive device, when the plasma bag is driven to shake back and forth, there are problems such as the plasma bag's inertia is large, and the insulation isolation bag containing the plasma bag accidentally collides and squeezes each other. The traditional fixed connection method is also inconvenient to disassemble, resulting in the risk of damage and leakage. For this reason, the present application improves the connection method between the device and the oscillation drive device, such as Figure 1 、 Figure 4 、 Figure 6 As shown, the cantilever hanging assembly 3 includes a Z-shaped hanging plate 30 and a T-shaped connecting plate 31;

[0049] The Z-shaped hanging plate 30 is composed of a connecting plate surface 300 that is arranged horizontally and connected to the oscillation driving device, a transition plate surface 301 formed by the front edge of the connecting plate surface 300 being bent downward and extended, and a hanging plate surface 302 formed by the lower edge of the transition plate surface 301 extending forward; the front edge of the hanging plate surface 302 is divided and extends upward and downward to form a plurality of upper connecting plate surfaces 303 and lower connecting plate surfaces 304; the horizontal arm of the T-shaped connecting plate 31 is connected to the positioning plate frame 10, and the vertical arm part of the T-shaped connecting plate 31 is provided with a horizontal strip hole 31a; the hanging plate surface 302 is inserted into the horizontal strip hole 31a, and the lower connecting plate surface 304 is against the rear end face of the vertical arm of the T-shaped connecting plate 31.

[0050] On the one hand, by utilizing the cantilever support structure, when oscillating to the extreme position, the Z-shaped cantilever deforms itself during the oscillation process, forming a buffer between the sudden change in speed of the driving equipment and the change in speed of the support component. On the other hand, the entire support component can be quickly replaced in conjunction with the T-shaped connecting plate, which facilitates quick operation and improves the efficiency of batch thawing.

[0051] In order to enhance the fixing effect and optimize the stress distribution of the heat preservation and isolation bag at the same time, in this embodiment, the strip-shaped buckling holes 10b are arranged on both long sides of the strip-shaped positioning holes 10a and extend along the length direction of the strip-shaped positioning holes 10a.

[0052] To avoid friction damage between the heat preservation and isolation bag and the edge of the plate rack during oscillation in the water bath, the lower edges of the supporting plate racks 11 are bent towards their inner side walls respectively to form a smooth arc surface 111 for avoiding cutting and wear at their lower edges.

[0053] Furthermore, in order to further enhance the stability of the supporting components during oscillation in the water bath, in this embodiment, a reinforcing plate 12 is provided at the bottom of the supporting plate surface 100 and between adjacent strip-shaped positioning holes 10a; the reinforcing plate 12 extends along the length direction of the strip-shaped positioning holes 10a and is perpendicular to the supporting plate surface 100; a number of clearance grooves 12a are provided on the reinforcing plate 12 opposite to the strip-shaped buckling holes 10b.

[0054] The reinforcing plate 12 helps to further improve the strength of the plate rack and ensure stability during the oscillation thawing process.

[0055] Furthermore, for the convenience of use and to improve flexibility, a movable buckle structure or connection holes are provided on the connection surface between the buckling plate surface 101 and the strip-shaped plate surface 110, and the buckling plate surface 101 and the strip-shaped plate surface 110 are detachably connected by movable buckles or screws.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
