Abstract
Description
Technical Field
[0001] The utility model relates to the field of laboratory technical equipment, in particular to a vibrating placenta cleaning device for laboratory use. Background Art
[0002] Stem cells are widely used in biomedical research. Among them, perinatal placental tissue can be used as a good source of stem cells because it contains rich types of stem cells. Since the placenta is exposed to the air during collection and there are microorganisms on its outer surface, we usually need to clean the surface of the placenta before obtaining stem cells from the placenta. Moreover, during the placenta preparation process, the placenta cleaning process is particularly important. Whether the placenta is thoroughly cleaned has a great impact on the subsequent bacterial examination results after placenta preparation. At present, the placental tissue cleaning process is usually manual cleaning, using oval forceps, tweezers, hemostatic forceps to hold or directly hold the placental tissue for flushing. This cleaning method has problems such as incomplete cleaning, cumbersome process, long time consumption, and easy to fall and contaminate.
[0003] Patent CN202120726160X proposes a placenta cleaning device, including a square opening on the surface of a workbench, with side guide plates extending obliquely from top to bottom toward the middle fixedly arranged around the square opening, and a cleaning cylinder extending downward fixedly arranged on the through opening surrounded by the side guide plates in the middle of the square opening, the bottom of the cleaning cylinder is hemispherical and is provided with a drain pipe, and the interior of the cleaning cylinder is provided with a storage rack and a filter rack from top to bottom in sequence; the placenta cleaning device also includes a water outlet faucet connected to a water inlet hose. This utility model patent is provided with a water inlet and outlet, which reduces the process of operators frequently adding and pouring cleaning liquid, but because there are many wrinkles on the outer surface of the placenta, during cleaning, the presence of wrinkles may cause the cleaning liquid to not fully contact with the placenta, resulting in incomplete cleaning. Therefore, we designed a new placenta cleaning device for laboratory use to solve the problem of easy falling of the placenta cleaning and insufficient contact between the cleaning liquid and the placenta. Utility Model Content
[0004] The technical problem to be solved by the utility model is that the placenta tissue cleaning process is usually manual cleaning, using oval forceps, tweezers, hemostatic forceps to hold or directly hold the placenta tissue for washing. There are many wrinkles on the outer surface of the placenta. When cleaning, the presence of wrinkles may cause the cleaning liquid to not fully contact with the placenta. This cleaning method has the problems of incomplete cleaning, cumbersome process, long time consumption, easy to fall and contaminate, etc.
[0005] In order to solve the above technical problems, the utility model adopts the following technical means:
[0006] A vibrating placenta cleaning device for laboratory use comprises a placenta cleaning device body, wherein the placenta cleaning device body is provided with a bottom plate, a top tray, a bottom tray, a vibrating device and a liquid storage bottle; a supporting structure is provided below the bottom plate, a working interface is provided above the bottom plate, and vibrating devices are provided on the left and right sides of the working interface, and the vibrating device is composed of a spring, a rack, a half gear and a gear bracket; a semicircular cavity is provided in the middle of the working interface, and a top tray and a bottom tray are arranged in the cavity, a drainage structure is provided at the bottom of the top tray, and a bottom tray is provided below the top tray, and the top tray and the bottom tray have the same shape, the bottom tray has a diameter larger than the top tray, and the top tray can be placed on the bottom tray. The utility model provides a vibrating placenta cleaning device for laboratory use, which is convenient for fully cleaning the placenta, reducing the risk of bacterial infection, and liberating productivity at the same time.
[0007] As a preferred embodiment, a further technical solution of the utility model is:
[0008] The supporting structure is a supporting column, and there are four supporting columns, which are arranged at four angles of the bottom plate.

A liquid guiding hose is arranged in the middle of the bottom tray, and one end of the liquid guiding hose is connected to the liquid storage bottle.
[0011] The liquid-conducting hose is provided with a valve body, and the valve body controls the opening and closing of the liquid-conducting hose.
[0012] The toothed portion of the half gear in the vibration device engages with the rack. After the half gear rotates, it can drive the rack to move downward. The downward moving rack stretches the spring connected to its upper portion, and the entire bottom tray moves downward. The toothless portion of the half gear cannot engage with the rack. Under the rebound effect of the spring, the spring, rack, and bottom tray move upward to form a cyclically vibrating bottom tray.
[0013] The device comprises a first group of vibration devices arranged on the left side and a second group of vibration devices arranged on the right side, and the first group of vibration devices and the second group of vibration devices are of left-right symmetrical structure.
[0014] Side walls are arranged around the working interface above the bottom plate, a sealed space is formed between the bottom plate, the bottom tray and the side walls, and the vibration device is arranged in the sealed space.
[0015] The utility model discloses a vibrating placenta cleaning device for laboratory use. During the cleaning process, the placenta does not need to be moved, so the problem of the placenta being easily dropped during cleaning can be solved. Meanwhile, a vibrating device is provided to solve the problem of insufficient contact between the cleaning liquid and the placenta. BRIEF DESCRIPTION OF THE DRAWINGS
