Technical Field

[0001] The utility model relates to the technical field of collagen extraction, in particular to an extraction device for medical collagen. Background Technique

[0002] Medical collagen is a kind of collagen for special purposes, and its sources can be animal tissues, such as cowhide, pigskin, etc. Collagen is a protein mainly existing in animal connective tissues, and has good biocompatibility and biological activity. In the medical field, medical collagen is usually used in aspects such as filling materials, dressings or scaffolds to promote tissue repair and regeneration. It has good absorbability, can be well integrated with human tissues, and is gradually metabolized and absorbed by the human body within a certain period of time, without causing long-term effects on the human body.

[0003] At present, the ordinary extraction devices for medical collagen on the market are inconvenient to disassemble and assemble, resulting in troublesome internal cleaning of the devices and incomplete discharging. Moreover, most of the ordinary extraction devices directly connect the filter screen and the reaction barrel. After pouring the materials, filtration has to be carried out before waiting for them to fully react, resulting in serious loss of collagen. It is not easy to control the timing of filtration for the devices, and they are not convenient to use.

[0004] Therefore, we propose an extraction device for medical collagen to solve the above problems. Content of the Utility Model

[0009] Preferably, square grooves are formed at both ends of the top end of the top cover. A dust-proof cover is hinged near the square grooves at the top end of the top cover, and the size of the dust-proof cover is adapted to the size of the square grooves.

[0010] Preferably, multiple groups of sealing plates are provided. The multiple groups of sealing plates are equidistantly distributed in a circumferential array manner at the bottom end of the turntable.

[0024] Further, the bottom end of the top cover 5 is provided as a sealing ring plate, and the sealing ring plate is slidably inserted into the inner part of the top end of the main protection barrel 1. As shown in the attached Figure 2 and the attached Figure 3 , the main protection barrel 1 and the top cover 5 are directly clamped tightly and are not easy to leak.

[0025] Further, a fastening bolt 8 is threadedly inserted at the top end of the main protection barrel 1, and a plurality of groups of fastening bolts 8 are provided. The plurality of groups of fastening bolts 8 are equidistantly distributed in a circumferential array manner at the top end of the main protection barrel 1. One end of the fastening bolt 8 passes through the main protection barrel 1 and is threadedly connected with the bottom end of the top cover 5. As shown in the attached Figure 2 , the main protection barrel 1 and the top cover 5 are directly fixed firmly, and the purpose of detachable connection between the two can be achieved.

[0026] Further, square grooves are opened at both ends of the top end of the top cover 5. A dust-proof cover 9 is hinged near the square grooves at the top end of the top cover 5, and the size of the dust-proof cover 9 is adapted to the size of the square grooves. As shown in the attached Figure 2 , the material can be smoothly poured into the device, and at the same time, no dust or the like will enter when the device is working.

[0027] Further, a plurality of groups of sealing plates 10 are provided. The plurality of groups of sealing plates 10 are equidistantly distributed in a circumferential array manner at the bottom end of the turntable 7. The sealing plates 10 are slidably inserted on the side of the reaction and filtration barrel 12. Both sides of the inner wall of the sealing plate 10 are closely attached to the inner wall and the outer wall of the reaction and filtration barrel 12 respectively. The length of the sealing plate 10 is equal to the height of the reaction and filtration barrel 12. As shown in the attached Figure 1 , the attached Figure 3 and the attached Figure 4 , it is convenient to effectively block the filter hole position of the reaction and filtration barrel 12 by using the sealing plate 10 to prevent leakage.

[0028] Further, a filter screen plate is arranged in the middle of the reaction and filtration barrel 12, and a plurality of groups of filter screen plates equal in number to the sealing plates 10 are provided. The size of the filter screen plate is smaller than the size of the sealing plate 10, and the interval size between every two groups of filter screen plates is larger than the size of the sealing plate 10. As shown in the attachedFigure 4 and the attachment Figure 5 As shown, collagen and other impurities can be effectively separated, and the separation time of the two can also be controlled by the rotation angle of the sealing plate 10.

[0029] Working principle: When in use, first place the device on the external support frame, then connect to the mains power to power on the whole device, and then open the dust cover 9 to pour the material containing collagen and the extraction solvent into the reaction and filtration barrel 12. The support frame 11 supports the reaction and filtration barrel 12. Then, use the control panel 2 to turn on the motor 6. The motor 6 is a DC brushless motor with stable rotation speed and low noise. The output end of the motor 6 drives the central shaft 13 to rotate, and the central shaft 13 drives the stirring rod 14 to rotate. The stirring rod 14 stirs the material in the reaction and filtration barrel 12 to fully mix the extraction solvent with the material, accelerating the decomposition of the material. After the collagen is mostly precipitated, rotate the turntable 7 to make the sealing plate 10 rotate synchronously. After the sealing plate 10 is far away from the filter plate of the reaction and filtration barrel 12, the user can check through the perspective frame 4 whether the sealing plate 10 blocks the position of the filter plate of the reaction and filtration barrel 12. Then, the impurities with smaller molecules flow through the filter plate into the main protection barrel 1 and flow out of the device along the impurity discharge pipe 3, while the collagen with larger molecules remains inside the reaction and filtration barrel 12, completing the extraction of collagen.

[0030] After the extraction is completed, the fastening bolt 8 can be screwed out, and the top cover 5 can be pulled out from the main protection barrel 1. The turntable 7 and the sealing plate 10 are synchronously separated from the sealing plate 10. Then, the reaction and filtration barrel 12 can be taken out from the main protection barrel 1, and the collagen in the reaction and filtration barrel 12 can be taken out. The above is the whole working principle of the present utility model.
