Description

Technical Field

[0001] This utility model relates to the field of separation device technology, and in particular to a placental villus sampling and separation device. Background Technology

[0002] Stem cells are a type of pluripotent cell with self-renewal capacity. Under certain conditions, they can differentiate into various APSC pluripotent cells, representing a type of primitive cell with self-replication and multi-directional differentiation potential. In other words, stem cells maintain an undirected differentiation state and possess proliferative capacity, earning them the medical term "universal cells." Stem cells originate from embryonic and fetal tissues. Embryonic stem cells from these tissues possess pluripotent differentiation characteristics, capable of differentiating into almost all of the more than 200 mature cell types found in a mature individual. After isolating stem cells from different human placental tissues, they undergo testing and identification, and are then cryopreserved at -196°C for resuscitation and reinfusion when clinically needed to treat diseases. However, direct sampling of placental villi is relatively difficult; therefore, villi separation is necessary to improve sampling efficiency.

[0003] The existing Chinese patent publication number CN 217140618 U discloses a separation device for separating the decidua of the placental wall and the placental chorion. According to the description of the device, it is known that the device first crushes the placental tissue by stirring and crushing the component, and then controls the screen cylinder to rotate for centrifugal separation. By separating the two steps, the separation efficiency of the device is reduced to a certain extent.

[0004] Therefore, it is necessary to provide a new placental villus sampling and separation device to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a placental villus sampling and separation device.

[0006] The placental villus sampling and separation device provided by this utility model includes: an outer shell, a separation cylinder rotatably connected inside the outer shell, side plates fixedly connected on both sides of the separation cylinder, and a separation component inside the separation cylinder;

[0007] The separation assembly includes a drive motor, which is mounted on the outer wall of a side plate and extends to the outside of the housing. The side plate away from the drive motor has symmetrically distributed and rotatably connected support rods, and the outer walls of the two support rods are provided with a plurality of staggered cutting blades.

[0008] Preferably, the ends of the two support rods away from the drive motor extend through the separator cylinder to the outside of another side plate, and the outer wall of the support rod is rotatably connected to the inner wall of the corresponding side plate.

[0009] Preferably, the two support rods are provided with the same rotatable linkage ring at one end outside the separation cylinder, and the linkage ring is rotatably connected to the inner wall of the outer shell.

[0010] Preferably, a rotatably connected adapter rod is provided on the outer wall of the side plate away from the drive motor. The end of the adapter rod away from the separator cylinder is fixedly connected to the inner wall of the outer shell, and a fixedly connected adapter toothed disc is sleeved on the outer wall of the adapter rod.

[0011] Preferably, a linkage gear plate is fixedly connected to the outer wall of the support rod, and the linkage gear plate and the adapter gear plate are meshed together.

[0012] Preferably, the side wall of the separating cylinder is provided with an installation groove, the installation groove is provided with a movable plate, the movable plate is fixedly connected to the installation groove by bolts, and a number of evenly distributed filter holes are provided between the separating cylinder and the movable plate.

[0013] Preferably, a support plate is provided inside the outer shell, and a plurality of evenly distributed cleaning strips are provided on the opposite surfaces of the two support plates, and the ends of the cleaning strips abut against the inner wall of the filter holes in the separation cylinder and the movable plate.

[0014] Compared with related technologies, the placental villus sampling and separation device provided by this utility model has the following beneficial effects:

[0015] 1. By setting up the separation component, this utility model allows the internal cutting blade to rotate simultaneously through the meshing of the outer linkage toothed disc and the adapter toothed disc when the drive motor drives the separation cylinder to rotate during use. This enables the simultaneous crushing and centrifugation of the placenta, thereby improving the separation efficiency of the device.

[0016] 2. By placing the component driving the cutting blade on the outside of the separating cylinder, this utility model can reduce the probability of debris and other impurities falling between the linkage toothed disc and the adapter toothed disc and causing jamming failure of the driving component during use.

[0017] 3. This utility model has cleaning strips installed on both sides inside the outer shell. During the rotation of the separation cylinder, the cleaning strips can smoothly abut against the outer wall of the separation cylinder, thereby achieving scraping and cleaning of the filter holes inside the separation cylinder and the movable plate. This reduces the probability of filter hole blockage and improves the user experience and separation effect of the device. Attached Figure Description

[0024] 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.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] Please see Figures 1 to 5 The present invention provides a placental villus sampling and separation device, which includes: a shell 1.

[0027] In the embodiments of this utility model, please refer to Figures 1 to 5The outer casing 1 houses a rotatably connected separation cylinder 2. Both sides of the separation cylinder 2 are fixedly connected to side plates 21. A separation assembly 3 is located inside the separation cylinder 2. The separation assembly 3 includes a drive motor 31, which is mounted on the outer wall of one side plate 21 and extends to the outside of the outer casing 1. Symmetrically distributed and rotatably connected support rods 32 are located on the side of the side plate 21 away from the drive motor 31. Several staggered cutting blades 321 are located on the outer walls of the two support rods 32. The ends of the two support rods 32 away from the drive motor 31 extend through the separation cylinder 2 to the outside of the other side plate 21. The outer wall of the support rod 32 is rotatably connected to the inner wall of the corresponding side plate 21. The two support rods 32 are provided with the same rotatably connected linkage ring 33 at one end outside the separation cylinder 2. The linkage ring 33 is rotatably connected to the inner wall of the outer shell 1. The outer wall of the side plate 21 away from the drive motor 31 is provided with a rotatably connected adapter rod 34. The end of the adapter rod 34 away from the separation cylinder 2 is fixedly connected to the inner wall of the outer shell 1. The outer wall of the adapter rod 34 is fitted with a fixedly connected adapter gear 341. The outer wall of the support rod 32 is fitted with a fixedly connected linkage gear 331. The linkage gear 331 and the adapter gear 341 are meshed together.

[0028] It should be noted that during use, the drive motor 31 can be controlled to drive the separation cylinder 2 to rotate, thereby driving the internal placenta to rotate and achieving centrifugal operation. During this process, the separation cylinder 2 will drive the internal support rod 32 and its end linkage ring 33 to rotate. The rotating support rod 32 will drive the linkage toothed disc 331 on the outer wall to rotate synchronously around the center of the cleaning cylinder. While the linkage toothed disc 331 rotates around the separation cylinder 2, it will drive the internal support rod 32 to rotate inside the separation cylinder 2 through meshing with the adapter toothed disc 341. At this time, the rotating support rod 32 will drive the cutting blade 321 to rotate, thereby realizing the crushing of the placenta inside the separation cylinder 2, and thus realizing the simultaneous crushing and centrifugal separation of the placenta.

[0029] In the embodiments of this utility model, please refer to Figures 1 to 5 The side wall of the separator 2 is provided with an installation groove 22, and a movable plate 23 is provided in the installation groove 22. The movable plate 23 is fixedly connected to the installation groove 22 by bolts, and a number of evenly distributed filter holes are provided between the separator 2 and the movable plate 23.

[0030] It should be noted that: after the placenta is separated and the material in the outer shell 1 is discharged through the installation of the movable plate 23, the movable plate 23 can be opened and the separation cylinder 2 can be rotated so that the material in the separation cylinder 2 can be automatically thrown out from the mounting groove 22 into the outer shell 1, thus realizing automatic material discharge.

[0031] In the embodiments of this utility model, please refer to Figures 1 to 5The outer casing 1 is equipped with a support plate 11. The opposing surfaces of the two support plates 11 are provided with a number of evenly distributed cleaning strips 12, and the ends of the cleaning strips 12 abut against the inner walls of the filter holes in the separation cylinder 2 and the movable plate 23.

[0032] It should be noted that the cleaning strip 12 is made of silicone. During use, as the separation cylinder 2 rotates, the cleaning strip 12 can smoothly abut against the outer wall of the separation cylinder 2, thereby scraping and cleaning the inside of the filter holes in the separation cylinder 2 and the movable plate 23, which can reduce the probability of filter hole blockage and thus improve the user experience and separation effect of the device.

[0033] The working principle of the placental villus sampling and separation device provided by this utility model is as follows:

[0034] When using this device, the operator can first place the placenta to be separated into the separation cylinder 2, then fix the movable plate 23 to the separation cylinder 2, and then connect the top cover of the outer shell 1 to the outer shell 1.

[0035] At this time, the staff can control the drive motor 31 to rotate. The rotating drive motor 31 will drive the separation cylinder 2 to rotate through the side plate 21. The rotating separation cylinder 2 will drive the internal placenta to rotate, thus realizing centrifugal operation.

[0036] During this process, the separation cylinder 2 will drive the internal support rod 32 and its end linkage ring 33 to rotate. The rotating support rod 32 will drive the linkage toothed disc 331 on the outer wall to rotate synchronously around the center of the cleaning cylinder. While the linkage toothed disc 331 rotates around the separation cylinder 2, it will drive the internal support rod 32 to rotate inside the separation cylinder 2 through meshing with the adapter toothed disc 341. At this time, the rotating support rod 32 will drive the cutting blade 321 to rotate, thereby realizing the crushing of the placenta inside the separation cylinder 2, and thus realizing the simultaneous crushing and centrifugal separation of the placenta.

[0037] While the separation cylinder 2 rotates, the cleaning strips 12 located on both sides inside the outer shell 1 can smoothly abut against the outer wall of the separation cylinder 2, thereby scraping and cleaning the inside of the filter holes in the separation cylinder 2 and the movable plate 23, which can reduce the probability of filter hole blockage and thus improve the user experience and separation effect of the device.

[0038] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0039] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
