Description

Technical Field

[0001] This utility model relates to the field of blood derivative technology, and in particular to a blood derivative molding device. Background Technology

[0002] With the continuous development of dental implantology, bone grafting has gradually become an ideal treatment option for tooth loss and edentulism. To improve the success rate of bone grafting and the speed of wound healing, and to resist the influence of adverse intraoral factors, since 2019, dental clinics have gradually used patient-derived blood derivatives such as CGF / PRF as a means to promote bone graft or wound healing. The specific procedure is as follows: 30-40 ml of blood is drawn from the patient, and 10 ml is placed in each centrifuge tube. The tube is then centrifuged at a high speed of 3000 rpm for 14 minutes. The blood will separate into two layers: the lower layer consists of dark red ruptured red blood cells and a portion of serum, approximately 5 ml; the upper layer is a pale yellow CGF / PRF segment, approximately 5 ml in volume. The upper layer is clinically necessary and contains a large amount of concentrated growth factors, which can improve the success rate of bone grafting and the speed of wound healing.

[0003] Currently, the clinical method for removing blood derivatives CGF / PRF after centrifugation is as follows: forceps or a needle holder are inserted into the centrifuge tube to remove the centrifuged blood derivatives. Then, medical staff use scissors to cut off the lower half. The blood derivatives are then placed on gauze or pressed into shape using a metal sheet. However, placing them on gauze or pressing them with a metal sheet often introduces impurities into the blood derivatives, causing contamination. Furthermore, the shape of the blood derivatives cannot be controlled using gauze or metal sheets, resulting in irregular shapes that are unsuitable for subsequent clinical use. Utility Model Content

[0004] To address the technical problems of existing technologies, such as the presence of impurities in blood derivatives due to placement on gauze or pressing with metal sheets, resulting in contamination of blood derivatives, and the inability to control the shape of the blood derivatives after molding, leading to irregular shapes that are not conducive to subsequent clinical use, this utility model provides the following technical solution.

[0005] This utility model discloses a blood derivative molding device, comprising a hollow box and an upper cover located on one side of the upper end of the box. A lower pressure plate located inside the box is provided on one side of the upper cover. The bottom of the lower pressure plate is provided with a plurality of micro-holes. A bracket is fixedly connected to the upper part of the box and spans above the lower pressure plate. A lower pressure column with a first handle at the upper end and a fixed upper pressure plate at the lower end is slidably connected to the bracket. A plurality of guide columns are fixedly connected to the upper pressure plate and slidably connected to the bracket. A plurality of limiting members are provided along the edge of the upper pressure plate. A plurality of positioning blocks are provided at the upper end of the box and are aligned vertically with the limiting members.

[0006] As a further technical solution, the limiting member includes a column located on the upper surface of the upper pressure plate, an adjusting end extending outward from the upper end of the column, an adjusting screw with a second handle at the upper end threadedly connected to the adjusting end, and a limiting block fixedly connected to the adjusting screw through the lower end of the adjusting end.

[0007] As a further technical solution, the limiting block and the positioning block are aligned in the same straight line in the vertical direction.

[0008] As a further technical solution, there are four limiting members, which are evenly arranged around the upper pressure plate, and the positioning blocks correspond one-to-one with the limiting members.

[0009] As a further technical solution, a spring is sleeved on the outer periphery of the pressure column, and the upper and lower ends of the spring are respectively fixedly connected to the first handle and the bracket.

[0010] As a further technical solution, a filter screen connected to the inner wall of the box is provided on one side of the lower pressure plate.

[0011] The beneficial effects of this utility model are as follows: the box body is equipped with a lower pressure plate, and the upper support of the box body is connected to the lower pressure column and the upper pressure plate. The upper and lower pressure plates are vertically aligned, which can press and shape the blood derivatives placed on the upper part of the lower pressure plate. The lower pressure column drives the upper pressure plate to slide up and down on the support, ensuring the relative stability of the upper and lower pressure plates. In addition, the upper pressure plate is equipped with limiting members around its perimeter. The limiting blocks of the limiting members correspond one-to-one with the positioning blocks around the upper perimeter of the box body, which can adjust the pressing height of the upper and lower pressure plates on the blood derivatives, effectively controlling the forming shape and stability of the blood derivatives, ensuring the morphological stability of the blood derivatives, and ensuring subsequent clinical use.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0017] In the description of this utility model, it should be understood that the terms "upper" and "lower" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0018] like Figure 1 and Figure 2 As shown, the present invention provides a blood derivative molding device, which includes a hollow box 1 and an upper cover 2 located on one side of the upper end of the box 1. The box 1 has a cavity for collecting the exudate generated during the extrusion molding of the blood derivative, and the upper cover 2 is used to cover the upper part of the cavity.

[0019] In a preferred embodiment, a lower pressure plate 3 located inside the housing 1 is provided on one side of the upper cover 2. A filter screen 10 connected to the inner wall of the housing 1 is provided on one side of the lower pressure plate 3. The filter screen 10 is used to filter the exudate generated during the extrusion molding of the blood derivative, allowing the exudate to flow into the cavity inside the housing 1. Thus, the inner walls of the housing 1 on three sides of the lower pressure plate 3 and the filter screen 10 form a cavity that can accommodate the blood derivative, in which the blood derivative is extruded and molded. The bottom of the lower pressure plate 3 is provided with several micropores 301. The exudate from the blood derivative after extrusion flows out through the micropores 301 and the filter screen 10 and flows into the cavity inside the housing 1 for other uses. The molded blood derivative remaining on the upper part of the upper pressure plate 3 after extrusion is collected and used.

[0020] In a preferred embodiment, a bracket 101 is fixedly connected to the upper part of the housing 1, spanning above the lower pressure plate 3. The bracket 101 has an inverted U-shaped structure. A lower pressure column 5 is slidably connected to the middle of the upper part of the bracket 101. A first handle 501 is provided at the upper end of the lower pressure column 5, and an upper pressure plate 4 is fixedly connected to the lower end of the lower pressure column 5. Pulling the first handle 501 can operate the lower pressure column 5 to rise or fall. When the lower pressure column 5 falls, it drives the upper pressure plate 4 to move downward, and compresses the blood derivative located between the lower pressure plate 3 and the upper pressure plate 4. The upper pressure plate 4 is fixedly connected to a plurality of guide columns 7 that are slidably connected to the bracket 101. In this embodiment, there are two guide columns 7. The guide columns 7 can make the raising and lowering of the upper pressure plate 4 more stable, and the compression of the blood derivative by the upper pressure plate 4 and the lower pressure plate 3 more stable.

[0021] A spring 6 is sleeved around the outer periphery of the pressing column 5. The upper and lower ends of the spring 6 are fixedly connected to the first handle 501 and the bracket 101, respectively. The presence of the spring 6 can prevent the blood derivative from being pressed down too quickly when operating the pressing column 5, and ensure the stability of the blood derivative forming process. After the blood derivative is pressed and formed, the pressing column 5 is released, and the spring 6 can make the pressing column 5 spring up, making it easy to take out the pressed blood derivative.

[0022] like Figure 3 As shown, in a preferred embodiment, the upper pressure plate 4 is provided with a plurality of limiting members 8 along its edge, and the upper end of the box body 1 is provided with a plurality of positioning blocks 9 that are aligned with the limiting members 8 in the vertical direction. There are four limiting members 8, which are evenly arranged around the upper pressure plate 4. The positioning blocks 9 correspond one-to-one with the limiting members 8. The molding height of the blood derivative can be adjusted by adjusting the height difference between the limiting members 8 and the positioning blocks 9.

[0023] Specifically, the limiting component 8 includes a column 801 located on the upper surface of the upper pressure plate 4, which is fixedly connected to the upper pressure plate 4. An adjusting end 802 extends outward from the upper end of the column 801. The adjusting end 802 is threadedly connected to an adjusting screw 803 with a second handle 804 at its upper end. The adjusting screw 803 passes through the lower end of the adjusting end 802 and is fixedly connected to a limiting block 805. The limiting block 805 and the positioning block 9 are aligned vertically. When the positioning block 9 abuts against the limiting block 805, the blood derivative between the lower pressure plate 3 and the upper pressure plate 4 is precisely pressed and formed. By turning the adjusting screw 803, the limiting block 805 can rise or fall, thereby adjusting the downward stroke of the upper pressure plate 4 and thus adjusting the height of the formed blood derivative between the lower pressure plate 3 and the upper pressure plate 4.

[0024] The preferred embodiments and examples of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments and examples. Within the scope of knowledge possessed by those skilled in the art, various changes or equivalent substitutions can be made without departing from the concept of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
