Description

Technical Field

[0001] The utility model relates to a medical device, in particular to a placenta tissue processing device. Background Art

[0002] At present, when processing placental tissue and extracting placental hematopoietic stem cells, the tissue is cut into pieces manually. The process is time-consuming and labor-intensive, and is prone to contamination. Moreover, due to differences in manual operation, the size of the processed tissue fragments varies. When sieving later, the hematopoietic stem cells cannot be completely released, affecting the efficiency of cell extraction. Because the placental tissue is relatively large, only a small part can be processed each time during manual processing. Usually, a large number of consumable containers are required to hold the tissue to be processed when processing the placental tissue once. When cutting, the cutting process can only be performed in sequence. In addition, after cutting, it must be moved to a fine sieve for sieving. The experiment involves multiple tissue transfers, which increases the risk of tissue falling and contamination. During sieving, because the bottom area of ​​the fine sieve is large and the tissue dispersion range is large, a large part of the hematopoietic stem cells obtained by filtration are contaminated with the fine sieve and the inner wall of the collection cup, reducing the collection efficiency. Summary of the invention

[0003] In order to solve the problems of the prior art, the utility model provides a placenta tissue processing device, which can not only realize the electric crushing of placenta tissue, but also can directly perform sieving collection and anticoagulation storage, so as to facilitate the further extraction of hematopoietic stem cells at a later stage.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A placenta tissue processing device comprises a cover body, a crushing and stirring assembly is arranged in the cover body, a first cup body is screwed to the bottom of the cover body through a thread, the first cup body is used to accommodate the blade of the crushing and stirring assembly, a second cup body is screwed to the bottom of the first cup body through a thread, a filter screen and a funnel are arranged in the second cup body, a third cup body is screwed to the bottom of the second cup body through a thread, and an anticoagulant is accommodated in the third cup body.

[0006] Preferably, the crushing and stirring assembly includes a motor disposed in the cover body, the motor is connected to the blade via a rotating shaft, the motor is electrically connected to a control switch disposed on the surface of the cover body, and the motor is also electrically connected to a stepless speed controller.

[0007] Preferably, the first cup body, the second cup body and the third cup body are transparent cup bodies.

[0008] Preferably, the filter card is embedded in the upper part of the inner wall of the second cup body.

[0009] Preferably, the funnel is embedded in the lower part of the inner wall of the second cup body.

[0010] The beneficial effects brought by the technical solution provided by the utility model are:

[0011] 1. This device is a sealed whole that can prevent the tissue from contacting the outside world and avoid contamination. Compared with the traditional manual processing of placental tissue, this device saves time and effort. By adjusting the speed, it can be crushed to an ideal size, which is convenient for cell extraction.

[0012] 2. This device is equipped with stepless speed change. Because the tissue blocks are of different sizes when extracting placental hematopoietic stem cells, this device can be designed to evenly break the collected tissue blocks by adjusting different speeds.

[0013] 3. The tissue processing cup of this device is larger, which can provide a larger processing space for processing placental tissue and process all the tissues required for this experiment at one time.

[0014] 4. The third cup body of the tissue processing device can be used to hold the tissue to be processed. The tissue blocks cut from the placenta can be directly placed in this tissue processing cup to avoid clamping the tissue blocks back and forth, and solve the problem of tissue block falling and contamination.

[0015] 5. The tissue processing blade and connecting shaft of the device are detachable, autoclave-sterilizable, and reusable, thus reducing costs.

[0016] 6. The tissue processing cup of the device is transparent and visible, so the tissue crushing situation can be closely observed during the crushing process, and the speed and time can be adjusted according to the situation. In addition, the first cup body, the second cup body, and the third cup body can be easily disassembled from each other for easy cleaning.

[0017] 7. The second cup of the device is provided with a filter and a funnel, which can filter and collect hematopoietic stem cells in time during the crushing process and flow them into the sampling cup through the funnel, thereby preventing the cells from contaminating the inner wall of the tissue processing cup during the collection process and improving the collection efficiency.

[0018] 8. The third cup of the device has a built-in anticoagulant. After connecting the tissue processing cup, the hematopoietic stem cells are collected in the sampling cup, which can effectively and quickly play an anticoagulant role and improve the sample quality.

[0019] In summary, this device can independently complete the experimental operation processes of tissue fragmentation, tissue filtration, cell extraction, and sample collection, and after completion, placental hematopoietic stem cells can be obtained conveniently and efficiently.
