Whether whole blood transfusion or component transfusion, more medical auxiliary equipment is needed, for example, a needle tube is needed in the blood sampling stage; in the preservation stage, a preservation bag and the like are needed; in the blood transfusion stage, an intravenous injection and the like are required. Because the timing of donor delivery and the timing of patient demand often are difficult to match in real time, the collected blood product needs to be preserved for a period of time to cope with the clinical demands that may occur at any time. However, with the lengthening of the preservation time, the blood cells in the blood product are gradually inactivated and die, so that the clinical treatment effect is difficult to be expected. In order to improve the effect of surgery or therapy, it is necessary to improve the quality of blood products as much as possible during preservation, and therefore, how to preserve blood products has become a focus of medical attention.
The existing blood products are usually placed in transparent plastic bags and stored in a freezer at a low temperature to reduce the metabolism level of blood cells, even in transportation, the blood products are required to be placed in a specific preservation environment protected from light at a low temperature, otherwise, once the blood products are separated from the specific preservation environment, the blood products are extremely easy to deteriorate due to massive inactivation and death of the blood cells, so that the preservation time of the blood products is short, and the use is inconvenient.

In one aspect of an embodiment of the present invention, and with reference to FIG. 1, there is provided a blood product light energy storage bag comprising: an inner bag 101 and an outer bag 100 wrapped around the inner bag 101; the inner bag 101 is used for accommodating blood products; an interlayer is formed between the outer bag 100 and the inner bag 101, and a light emitting assembly is disposed in the interlayer, and the light emitting assembly is used for emitting weak light toward the inner bag 101.
For example, as shown in fig. 1, an outer bag 100 is wrapped around the outside of an inner bag 101, and a sandwich, i.e., a cavity, is formed between the inner and outer bags. The light emitting component (i.e. the light strip 102 in fig. 1) is arranged in the interlayer, and the light emitting component is electrified, so that the light emitting component emits weak light, the weak light irradiates on the blood product in the inner bag body 101, and the biostimulation effect of the weak light on the blood product is utilized, namely, when the blood product is irradiated by the weak light, the light quanta in the laser can be absorbed by the components of the blood product and converted into internal energy, so that the effect of activating the components of the blood product is achieved, and the blood product can keep certain activity in an active mode, namely, the inactivation trend of the components of the blood product (the components inevitably die gradually after the blood product is separated from the body) plays a certain role in retarding or blocking. Therefore, when the blood products are in the preservation environment, the preservation quality of the blood products under the same preservation period can be further improved or the preservation time of the blood products can be prolonged, and the shortage of the blood products in the existing blood warehouse in quantity can be relieved to a certain extent due to the prolongation of the preservation time. After the blood product is separated from a specific preservation environment, weak light irradiation can be continuously provided for the blood product, the weak light irradiation is performed on the blood product, living cells in the blood product can be effectively activated and maintained, the yield of preservation and transportation of the blood product after the blood product is separated from the body can be improved, the blood product can be kept to have certain activity by means of the stimulation, further the preservation time is prolonged, more treatable time is provided for clinical medical treatment, and the effect of operation or treatment is effectively improved. Meanwhile, the blood product light energy storage bag in the application can be directly improved on the basis of the existing blood product storage bag, and is used as the inner bag body 101, and the outer bag body 100, the related light-emitting components and other structures are correspondingly arranged on the inner bag body, so that the blood product light energy storage bag has the related functions in the application, and has the advantages of simple structure and low manufacturing cost, and is suitable for being popularized and used in a large range.
When the blood product is irradiated by weak light, on the one hand, the activation of the weak light can reduce the alpha 1-antitrypsin and alpha 2-globulin level, so that the fibrinolytic system is activated and fibrinogen is reduced. Simultaneously, chromophores in the blood product can be activated and metabolized to be increased. Thus, components in the blood product are effectively activated, such as the structure and the function of cell membranes are changed, the distribution of membrane enzymes, receptors and surface charges is changed, the stability of the membrane is improved, and the deformability of red blood cells is enhanced.
On the other hand, when the blood product is left for a long period of time, coagulation occurs, mainly because of aggregation of erythrocytes in the blood product. The main factors affecting the aggregation index of erythrocytes are long-chain bridging between erythrocytes and reduction of the surface charge of erythrocytes, while the main factors affecting long-chain bridging between erythrocytes are fibrinogen content, and the more fibrinogen, the stronger bridging between erythrocytes, the stronger the aggregation ability of erythrocytes. Fibrinogen is produced primarily by the plasminogen-plasmin system, where plasminogen activator is composed of a variety of biological enzymes whose direction of displacement of protein molecules is specific, where the movement of the nuclei in the protein is in conformational motion, and the energy required to rotate about a single bond is much lower than the energy required to rotate about a long bond or change the angle between bonds. If the electron energy level changes, conformational movement of the nucleus occurs, and the electrons and conformational interaction result in the enzyme catalyzing, so that when the frequency of laser irradiation approaches the natural frequency of certain energy levels of the plasminogen activator molecule, electrons in the plasminogen activator molecule will transition between these energy levels. Thereby leading the nucleus in the plasmin activator molecule to move to generate allosteric effect, providing power for the fractal catalysis process of enzyme, activating the plasmin-plasmin system, decomposing more plasmin in plasma, dissolving the fibrin in plasma, reducing bridging fibrin acted between red blood cells, reducing the aggregation capability of the red blood cells, and simultaneously reducing the viscosity and blood sedimentation of blood. Meanwhile, as the activity of the red blood cells is increased, the immunity is improved, and the movement of the red blood cells is enhanced so as not to be easy to gather. Namely, the activity of components in the blood product is effectively improved by activating the activities of various enzymes, improving the rheology of blood, increasing the expression of related genes and the like.
Firstly, the weak light is distinguished by the intensity of biological effect generated after the weak light irradiates the biological tissue, and the weak light can be 280-10000nm, especially 380-2000nm, with the power output of 0.01-90mw/cm based on the irreversible damage to the target tissue (namely, the light which only positively and beneficially promotes and stimulates the biological tissue) 2 Between them. The laser light is not limited to stimulated radiation in this application, but may be other luminescence types of spontaneous radiation, etc., such as neon lights, fluorescent lights, LED lights, etc. For ease of understanding, the following will be described schematically by taking a weak laser (other types of light are similar to weak lasers) as an example (not to be understood as limiting the application), and the weak laser is not used for measuring the intensity of the laser by its own physical parameters in medicine, but is distinguished by the intensity of biological effects generated after the laser acts on biological tissues. The weak laser in the application refers to a laser with a weak response level which can not cause irreversible damage to target tissues when the organism is directly irradiated by low-intensity laser, and the laser stimulates the organism to generate a series of physiological and biochemical response reactions, plays a role in regulating, enhancing or inhibiting, and achieves the aim of activating cell activity. It is different from strong laser, and features low output energy and no light-heat effect, so that the local temp. rise caused by weak laser is not more than 0.1-0.75 deg.C, and the biological change of local tissue can not be caused. Weak laser generally refers to a power output of between 10 and 90mw and an energy density of between 1 and 4J/cm at the irradiation site 2 。
Second, the weak laser may be He-Ne laser (wavelength at 632.8 nm), gaAlAs laser (wavelength 820)830 nm), gaAs lasers (wavelength 904 nm), and so forth. Parameters of dim light: wavelengths are typically 632.8, 820, 830 or 904nm; the power is 10-90mw (a few can be less than 10mw or more than 100 mw); the waveform is continuous wave and pulse wave (1-4000 Hz); the energy density is 1-4J/cm 2 。
Third, the light emitting device may be a he—ne laser, a semiconductor laser, an LED lamp, or the like.
Fourth, the inner bag 101 and the outer bag 100 may be flexible bags, or the inner bag 101 may be a flexible bag, and the outer bag 100 may be a bag with a certain strength, so as to form a certain protection effect on the inner bag 101. For example, in one embodiment, the outer bag 100 and the inner bag 101 may be made of polyvinyl chloride (Polyvinyl chloride, PVC) material, which has the characteristics of high mechanical strength and good softness and elasticity. In addition, in another embodiment, the outer bag 100 and the inner bag 101 may be made of 1, 2-tetraphenyl ethylene (Thermoplastic Elastomer, TPE) which is mainly characterized by high elasticity, high strength and high rebound resilience, and at the same time, the main composition of the material is C 26 H 20 Therefore, the material also has the characteristics of environmental protection, no toxicity, safety, weather resistance, fatigue resistance, temperature resistance and the like. When the outer bag 100 is a bag having a certain strength, it may be made of polypropylene (PP), which has not only chemical resistance and good high abrasion resistance, but also toughness of high strength, so that the finished product thereof can have a certain strength, thereby forming good protection capability for the inner flexible inner bag 101.
Fifth, correspondingly, in order to further ensure the stability of the arrangement of the light emitting component, the light emitting component may be fixedly arranged or detachably arranged on the outer surface of the inner bag body 101, or may be fixedly arranged or detachably arranged on the inner surface of the outer bag body 100.
Further, for the arrangement form of the above-described light emitting assembly, one example is: the light-emitting component only comprises weak light with fixed wavelength and fixed power output, and is arranged in an interlayer between the inner bag body 101 and the outer bag body 100, when a blood product is arranged in the inner bag body 101, the light-emitting component can emit the weak light with the specific wavelength and the specific power output to the blood product by controlling a switch button connected with the light-emitting component to be in an open state, so that the effect of activating the activity of the components in the blood product is achieved. Because of the different blood components used for whole blood transfusion and component transfusion, blood products also generally include a variety of plasma products of different components, such as platelet products, clotting factor products, fibrinogen products, and the like. In order to further improve the effect of weak light on the activation of the blood products, the weak light which is more suitable for the blood products with different components can be arranged, so that the scientificity and the flexibility of the light energy storage bag for the blood products in the application are further improved from the aspect of using effect. Meanwhile, different marks corresponding to blood products with different components can be arranged on the outer surface of the outer bag body 100 of the blood product light energy storage bag, for example, different colors can be used for distinguishing, and colors, symbols, fonts and the like can be used for distinguishing, so that confusion is not easy to occur in actual use, and the convenience in use is improved.
Another embodiment: the light-emitting component comprises a plurality of low-light generators (which can be light bands 102 or light beads) with different wavelengths and different output powers, and the low-light generators are reasonably arranged in the interlayer (so that the blood products in the inner bag body 101 can be uniformly irradiated). Meanwhile, a mode selection knob, a touch screen, a mode key and the like can be further arranged on the outer bag body 100 and connected with the light-emitting component, so that the blood product light energy storage bag can flexibly select a corresponding mode according to the type of blood product filled in the blood product light energy storage bag during use, the activation effect of the blood product light energy storage bag can be improved, and the use range and the automation degree of the blood product light energy storage bag can be also improved. The following will schematically illustrate the mode selection knob, which corresponds to both a mode and B mode, and may be provided with an off mode, i.e. a power-off mode. In use, the corresponding mode may be selected according to the type of blood product being loaded. In addition, there may be four modes, five modes, etc. (as with the three modes described above) so that the blood product light energy storage bag of the present application can support a greater variety of different compositions of blood products. In order to further reduce the manufacturing and use costs, the outer bag 100 and the inner bag 101 may be detachably connected (e.g., by a connection such as a zipper or a velcro), and the manufacturing and use costs may be reduced by using the outer bag 100 and the light emitting assembly several times.
Optionally, the blood product light energy storage bag further includes a first connector 103, one end of the first connector 103 is connected to the outer surface of the inner bag body 101, and the other end is connected to the inner surface of the outer bag body 100.
For example, referring to fig. 2, a first connecting piece 103 is further disposed in the interlayer, and the inner bag body 101 is connected with the outer bag body 100 through the first connecting piece 103, so that a certain connection relationship is formed between the inner bag body and the outer bag body, and mutual rotation between the inner bag body 101 and the outer bag body 100 can be effectively prevented, so that phenomena such as winding and dislocation are avoided. Meanwhile, the weak light emitted by the light-emitting component can be more stable in irradiating the blood product, and the situation that the weak light emitted by the light-emitting component is difficult to effectively irradiate the blood product due to rotation between the inner bag body and the outer bag body in the transportation process and the like is avoided. The stability of the blood product light energy storage bag in the embodiment when the blood product is stored is improved, namely the yield of the blood product in transportation or use is improved. It should be noted that the form of the first connector 103 may be various, and there are no specific restrictions in this application, and two of them will be schematically shown by way of example below:

Meanwhile, the setting positions can be uniformly distributed along the outer surface of the inner bag body 101, so that the inner bag body and the outer bag body can be uniformly limited at each position through the connection of the rubber columns, relative shaking between the two bag bodies is reduced, the device is suitable for scenes with stronger vibration environments, for example, after collection is completed, the device is placed on a place meeting the regulations for storage, and then long-distance transportation is needed when transportation is needed, the strength of the bag bodies can be enhanced, and the yield of blood products in transportation is further improved.
The inner bag 101 in the present application may be a conventional blood storage bag, and a transparent bag is generally used. Meanwhile, the outer bag 100 may be provided as an openable and closable bag, and the specific form of opening and closing may be that one side has an opening, or that three sides have openings (in this form, when opening, the opposite side walls of the outer bag 100 may be completely spread with the fourth side as a rotation center), and then the existing blood storage bag is placed therein, and the side of the outer bag 100 provided with the opening is closed, thereby achieving weak light irradiation. The convenience in use is further improved, and the cost in use can be effectively reduced.
In addition, the first connecting member 103 may be a protrusion provided on the inner wall of the outer bag 100 and a groove provided on the outer wall of the inner bag 101, respectively, so that the outer bag 100 and the inner bag 101 form a stable connection relationship by interference fit of the protrusion and the groove. At the same time, the inner bag body 101 and the outer bag body 100 are convenient to split when needed. Alternatively, the light emitting assembly is a light band 102, and the light band 102 is disposed around the outer circumference of the inner bag 101.

So long as it can ensure that the blood product is always irradiated with a sustained weak light.
Alternatively, the light strip 102 includes a first light strip 1021 and a second light strip 1022, the first light strip 1021 is wound around the outer circumference of the inner bag 101 in a first direction, and the second light strip 1022 is wound around the outer circumference of the inner bag 101 in a second direction, the first direction and the second direction intersecting.
For example, the light bands 102 may further include a plurality of light bands 1021 around the outer circumference of the inner bag 101 along the first direction, as shown in fig. 3, when the first light bands 1021 are provided in a spiral wound form, only one light band may be provided, and in order to further improve uniformity of weak light irradiation, the second light bands 1022 may also be provided in one light band, and directions in which the two light bands 102 spirally extend intersect, so that uniform weak light irradiation is formed on the blood product in the inner bag 101 in a crossed structure, wherein, in order to ensure the overall irradiation, both the starting end and the ending end of the first light band 1021 and the second light band 1022 should be provided at positions of both ends of the inner bag 101. In this embodiment, the inner bag 101 may be an existing blood bag (the existing blood bag is a bag similar to an infusion bag and is generally made of transparent plastic), and is combined with the outer bag 100, so that the first light band 1021 and the second light band 1022 may be disposed on the inner wall of the outer bag 100 for further improving the recycling rate of the outer bag 100 and the convenience of replacement of the inner bag 101, but the light emitting directions of the first light band 1021 and the second light band 1022 are corresponding to the blood products in the inner bag 101.

Similarly, the second light strips 1022 may be disposed in parallel with each other. And the corresponding first lamp strip 1021 and second lamp strip 1022 are perpendicular (not shown), so that a grid-shaped irradiation structure (refer to a grid-shaped structure in which the first direction and the second direction are intersected in fig. 3) is formed, and the requirement of the blood product on uniform weak light irradiation is met. Meanwhile, when the inner bag 101 is an existing blood bag, the first and second lamp bands 1021 and 1022 may be provided on the inner wall of the outer bag 100, as required when the above spiral arrangement is required.
Optionally, the light emitting assembly includes a plurality of light emitting members 104 disposed on the inner surface of the outer bag 100, and the plurality of light emitting members 104 are uniformly disposed along the inner surface of the outer bag 100.
