DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the present disclosure will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0023] The terms used in the embodiments of the present disclosure are only for the purpose of describing specific embodiments, and are not intended to limit the present disclosure. The singular forms "a", "said" and "the" used in the embodiments of the present disclosure and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings, and "multiple" generally includes at least two.

[0024] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0025] It should be understood that although the terms first, second, third, etc. may be used to describe structures in the disclosed embodiments, these structures should not be limited to these terms. These terms are only used to distinguish different structures. For example, without departing from the scope of the disclosed embodiments, a first component may also be referred to as a second component, and similarly, a second component may also be referred to as a first component.

[0026] As used herein, the words "if" and "if" may be interpreted as "at the time of" or "when" or "in response to determining" or "in response to detecting", depending on the context. Similarly, the phrases "if it is determined" or "if (stated condition or event) is detected" may be interpreted as "when it is determined" or "in response to determining" or "when detecting (stated condition or event)" or "in response to detecting (stated condition or event)", depending on the context.

[0027] It should also be noted that the term "includes", "comprising" or any other variation thereof is intended to cover non-exclusive inclusion, so that a commodity or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such commodity or device. In the absence of more restrictions, the elements defined by the sentence "comprising a ..." do not exclude the existence of other identical elements in the commodity or device including the elements.

[0028] In the related art, due to the inherent characteristics of the ultrasonic process, the temperature of the liquid in the ultrasonic treatment process will gradually rise. The rate of temperature rise is affected by the amount of treatment liquid, the amount of casings treated, the heat dissipation performance of the equipment, and the ambient temperature. Since the above factors are not easy to control, and casing biological materials are sensitive to temperature, the instability of the treatment liquid temperature will lead to uncontrollable performance of the casings, greatly increasing the application risk of the material; because the casings themselves have many wrinkles and are easy to float to the surface of the treatment liquid or sink to the bottom of the tank (determined by the density of the treatment liquid), the treatment liquid that reacts in the casing gathering area is not easy to spread to other areas, especially the outer tank. The ultrasonic treatment method has no effect on the movement of the casings. Because the casings are easy to float to the surface of the treatment liquid or sink to the bottom of the tank (determined by the density of the treatment liquid), the casings exposed to the liquid surface or wrapped inside cannot fully contact the treatment liquid, and the treated casings are easy to entangle and difficult to separate, which can easily lead to inconsistency in casing treatment, forming an uncontrollable risk. The related art generally uses a universal treatment tank with a relatively large bottom area, which makes it impossible to treat when the casing treatment volume is small and the treatment liquid is not fully utilized.

[0029] In order to solve at least one of the technical problems mentioned above, the present disclosure provides an animal-derived implantable biomedical material processing device and system, which are used for degreasing and inactivating pathogens in intestine casings. The animal-derived implantable biomedical material processing device includes: an operating table 100, wherein the operating table 100 has a top surface 110; a processing tank 200, wherein the processing tank 200 is opened on the top surface 110, and the processing tank 200 is configured to assemble a processing reagent; and a plurality of processing frames 300, wherein the processing frames 300 are at least partially detachable. Located in the processing tank 200, the side wall and the bottom surface of the processing frame 300 are mesh structures, and the processing frame 300 is configured to assemble biological materials and immerse the biological materials in the processing reagent; an oscillating device 400, the oscillating device 400 is arranged on the top surface 110, and the oscillating device 400 is configured to oscillate the processing frame 300; wherein, the processing frame 300 includes: an inflation unit 500, the inflation unit 500 is arranged in the processing frame 300, and the inflation unit 500 is configured to supply gas to the processing frame 300, and the gas supply pressure is 0.1-1MPa. The present invention realizes the simultaneous processing of multiple groups of casings by adopting multiple processing frames 300, thereby preventing the casings from clumping and increasing the processing area of ​​the casings; and, adopts an inflation unit 500 to bubble and stir the casings with compressed air, thereby preventing the high temperature in the processing tank 200 and reducing the risk of material denaturation during the casing processing; the bubbling and stirring can cause the casings to roll during processing, thereby increasing the processing effect; the simultaneous processing of multiple processing frames 300 has a significant improvement in the safety of medical devices.

[0030] The optional embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0031] Figure 1 FIG. 1 shows a schematic diagram of the structure of an animal-derived implantable biomedical material processing device according to an embodiment of the present disclosure. Figure 1 As shown, according to a specific embodiment of the present disclosure, on the one hand, an animal-derived implantable biomedical material processing device is provided, and the animal-derived implantable biomedical material processing device is used for degreasing and inactivating pathogens of casings, and the animal-derived implantable biomedical material processing device comprises: an operating table 100, and the operating table 100 has a top surface 110; a processing tank 200, and the processing tank 200 is opened on the top surface 110, and the processing tank 200 is configured to assemble a processing reagent; a plurality of processing frames 300, and the processing frames 300 are at least partially detachable and arranged on the operating table 100; The processing tank 200, the side wall and the bottom surface of the processing frame 300 are mesh structures, the processing frame 300 is configured to assemble biological materials and immerse the biological materials in the processing reagent; an oscillating device 400, the oscillating device 400 is arranged on the top surface 110, the oscillating device 400 is configured to oscillate the processing frame 300; wherein, the processing frame 300 includes: an inflation unit 500, the inflation unit 500 is arranged in the processing frame 300, the inflation unit 500 is configured to supply gas to the processing frame 300, and the gas supply pressure is 0.1-1MPa.

[0032] The present disclosure realizes the simultaneous processing of multiple groups of casings by adopting multiple processing frames 300, thereby preventing the casings from clumping and increasing the processing area of ​​the casings; the simultaneous processing of multiple processing frames 300 has a high improvement in the safety of medical devices. In an optional embodiment, when the processing frame 300 is assembled in the processing tank 200, the distance between the bottom surface of the processing frame 300 and the bottom surface of the processing tank 200 is controlled to be less than 30 mm. In an optional embodiment, when the processing frame 300 is assembled in the processing tank 200, the distance between the outermost processing frame 300 and the side wall of the processing tank 200 is controlled to be less than 20 mm. In an optional embodiment, when the processing frame 300 is assembled in the processing tank 200, the distance between two adjacent processing frames 300 is controlled to be less than 60 mm.

[0033] In some embodiments, it is found that as the processing volume of casings changes, the gas pressure has a certain influence on the processing results of casings. Taking fat removal as an example, an alcohol treatment solution is added to the treatment tank for 180 minutes. The casings after treatment are sent for inspection of fat content. After drying and crushing, the casings are tested with reference to the GB5009.6-2016 acid hydrolysis method. By comparing the degreasing effect, it can be seen that for casings with different processing volumes, the fat content of the casings decreases with the increase of gas pressure. When a certain gas pressure is reached, the fat content of the casings tends to be stable. For details of some experimental data, please refer to the table below.

[0034] Note: 0MPa means no gas is supplied, and the other parameters are the same as those of other groups of experiments.

[0035] The fat content of casings after being treated with different gas pressures is shown in the table above; In several groups of experiments, the 4kg experiment started from 0.45MPa, the 10g experiment started from 0.6MPa, the 20kg experiment started from 0.75MPa, the 30kg experiment started from 0.9MPa, and the 45kg experiment started from 1.2MPa. The casings were damaged after treatment (torn, broken or even shattered, and in the 4kg experiment, the 9MPa and 12MPa casings were already shattered).

[0036] In several experiments, the 4kg experiment started at 0.3MPa, the 10g experiment started at 0.45MPa, the 20kg experiment started at 0.6MPa, the 30kg experiment started at 0.75MPa, and the 45kg experiment started at 0.9MPa. The fat content of the casings after treatment decreased significantly. Combined with the above damage data, it can be seen that by using the gas transmission method disclosed in the present invention, the fat content of biomedical materials (casings) of different weights will be significantly reduced under a certain range of gas transmission pressures without damage. Through further research on the properties and arrangement of casing fat molecules, the following formula is obtained: In some embodiments, the gas delivery pressure satisfies the following formula: , Wherein, F is the gas transmission pressure, W D The total weight of the biomedical material in a wet state to be treated. Example 1

[0037] The gas delivery pressure F satisfies the following formula: , 4kg, 10kg, 20kg, 30kg and 45kg casings with a fat content of 7.68% were treated with the above gas pressure respectively. After 180 minutes of treatment, the casings were sent for fat content testing. After drying and crushing, the casings were tested with reference to GB5009.6-2016 acid hydrolysis method, and the untreated casings were used as comparison examples. Example 2

[0038] The gas delivery pressure F satisfies the following formula: , 4kg, 10kg, 20kg, 30kg and 45kg of sausage casings with a fat content of 7.68% and 20kg and 30 gas pressures were respectively processed. After 180 minutes of processing, the casings were sent for fat content testing. The testing method was the same as that in Implementation Case 1.

[0039] Comparative Example 1 4kg, 10kg, 20kg, 30kg and 45kg of casings with a fat content of 7.68% were treated with degreasing liquid in a gas-free mode. After 180 minutes of treatment, the casings were sent for fat content testing as blank comparison example 1. The inspection method was the same as that in implementation case 1.

[0040] Casing fat content test method: 1. Dry the casing, crush it with scissors and grinding equipment, then weigh about 2g~5g, accurate to 0.001g, put it in a 50mL test tube, add 8mL of water, mix well, and then add 10mL of hydrochloric acid. Put the test tube in a 70℃~80℃ water bath, stir it with a glass rod every 5min~10min until the sample is completely digested, about 40min~50min.

[0041] 2. Take out the test tube, add 10mL of ethanol and mix. After cooling, transfer the mixture into a 100mL stoppered measuring cylinder, wash the test tube several times with 25mL of anhydrous ether, and pour it into the measuring cylinder. After all the anhydrous ether is poured into the measuring cylinder, add a stopper and shake for 1min, carefully unscrew the stopper, release the gas, rescrew it, let it stand for 12min, carefully unscrew the stopper, and rinse the stopper and the fat attached to the mouth of the measuring cylinder with ether. Let it stand for 10min~20min, wait for the upper liquid to be clear, suck out the supernatant into a constant-weight conical flask, add 5mL of anhydrous ether into the stoppered measuring cylinder, shake, let it stand, and still suck out the upper ether and put it into the original conical flask.

[0042] 3. Evaporate to dryness in a water bath. Dry at 100℃±5℃ for 1 hour, cool in a desiccator for 0.5 hour and weigh. Repeat the above steps until constant weight is achieved (until the difference between two weighings does not exceed 2 mg).

[0043] After testing by the above method, the fat content of the casings after being treated in Example 1, Example 2 and Comparative Example 1 is as follows:

[0044] It can be seen from the above table that the weight fat content of the casings in Example 1 and Example 2 after treatment is significantly lower than the weight fat content of the casings in the comparative example after treatment. It can be seen that the treatment using the gas pressure of Example 1 and Example 2 is more thorough, and the excess fat, cells and DNA are removed more cleanly, and the fat removal effect is better. By comparing Example 1 and Example 2, it can be seen that the weight fat content of Example 2 after treatment is slightly greater than that of Example 1, which are casings of the same batch with the same weight before treatment; from the experimental data, it can be seen that the gas pressure in Example 1 is slightly greater than that in Example 2, therefore, under the premise of not damaging the casings, the higher the gas pressure, the cleaner the treatment, and the upper limit of the gas pressure adopted in the present disclosure is to prevent the casings from being damaged under high-frequency vibration.
