Description

Technical Field

[0001] The utility model belongs to the technical field of sampling of laboratory freeze-dried preparations, and specifically refers to a special sampling tool for freeze-dried preparation laboratories. Background Art

[0002] Freeze-dried blood products are a type of block made by freeze drying, which is mainly used in the fields of medical treatment, biological products, etc. During the preparation process, blood or blood products are subjected to a series of treatments, such as centrifugation, filtration, inactivation, etc., and then freeze-dried to form blocks. This type of preparation has good storage and stability, and can be stored for a long time.

[0003] During the quality inspection process, the freeze-dried preparation needs to be pre-treated to obtain a powdered test sample with uniform quality. For example, when determining the moisture content, the freeze-dried preparation block needs to be crushed into a powdered sample. However, existing sampling tools have some disadvantages.

[0004] First, the operation process of crushing freeze-dried drug blocks with stainless steel medicine spoons is cumbersome and laborious, and it is easy to introduce moisture from the environment, affecting the test results. Secondly, for the contents of molded bottles of different specifications, the operation of using stainless steel medicine spoons for sampling is more time-consuming and laborious. In addition, due to factors such as the shape and size of stainless steel medicine spoons, it is sometimes not convenient to crush freeze-dried drug blocks into uniform powder samples. Utility Model Content

[0005] In order to solve the problem that the existing stainless steel medicine spoon is suitable for sampling the contents in an open container but is inconvenient to crush bulk objects, the utility model provides a special sampling tool for freeze-dried preparation laboratories.

[0006] The technical solution adopted by the utility model is as follows: The utility model provides a special sampling tool for freeze-dried preparations in a laboratory, comprising a rod-shaped spoon handle and a spoon head arranged at one end of the rod-shaped spoon handle, and also comprising a first spoon tail and a second spoon tail, the first spoon tail and the second spoon tail being replaceably installed at the other end of the rod-shaped spoon handle, the first spoon tail comprising a cylindrical pressure head, the second spoon tail comprising a connecting curved rod, the other end of the connecting curved rod being provided with a longitudinal blade, the setting of the cylindrical pressure head can effectively crush freeze-dried preparations with different loading amounts and distributions, and process them into a uniform powder.

[0007] Furthermore, the spoon head is a concave ellipsoid, the two ends of the spoon body are rolled inward, and the connection with the rod-shaped spoon handle is tilted up by 15 degrees, so that powder can be easily taken out.

[0008] Furthermore, the surface of the rod-shaped spoon handle is provided with metal protrusions, and the arrangement of the metal protrusions on the surface of the spoon handle makes it easy to hold.

[0009] Furthermore, the longitudinal blade is triangular, and the lower end of the longitudinal blade is sharpened. The longitudinal blade is made of smooth and hard material, and the blade arrangement direction is on the same plane as the rod-shaped spoon handle. The setting of the longitudinal blade can effectively divide the freeze-dried preparation at the bottom of the entire bottle.

[0010] Furthermore, the cylindrical pressure head is made of a smooth and hard material, and the diameter of the cylindrical pressure head is smaller than the flat mouth diameter of the sampling bottle.

[0011] Furthermore, a bolt is provided at one end of the rod-shaped key handle, a screw hole is provided at one end of the column pressure head, and a screw hole is provided at one end of the connecting curved rod, so as to facilitate the connection of the replaceable key tail.

[0012] The beneficial effects achieved by the utility model using the above structure are as follows:

[0013] (1) The metal protrusions on the spoon handle make it easier to hold.

[0014] (2) The connection between the spoon head and the rod-shaped spoon handle is tilted up 15 degrees, which makes it easy to remove powder.

[0015] (3) The concave ellipsoid shape of the spoon head and the inward-rolled design at both ends of the spoon head can effectively prevent the powdered sample from spilling, making the sampling process more convenient.

[0016] (4) The setting of the longitudinal blade can effectively divide the freeze-dried preparation at the bottom of the bottle.

[0017] (5) The setting of the column press head can effectively crush freeze-dried preparations with different filling amounts and distributions and process them into uniform powder. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] like Figure 1-Figure 3 As shown, the utility model proposes a special sampling tool for freeze-dried preparation laboratory, including a rod-shaped spoon handle 1, the surface of the rod-shaped spoon handle 1 is provided with a metal protrusion, and a spoon head 2 arranged at one end of the rod-shaped spoon handle 1, the spoon head 2 is a concave ellipsoid, the two ends of the spoon body are rolled inward, and the connection with the rod-shaped spoon handle 1 is tilted upward by 15 degrees, and also includes a first spoon tail and a second spoon tail, the first spoon tail and the second spoon tail are replaceably installed at the other end of the rod-shaped spoon handle 1, the first spoon tail includes a cylindrical pressure head 4, the cylindrical pressure head 4 is made of a smooth and hard material, The diameter of the column pressure head 4 is smaller than the flat diameter of the sampling bottle. The column pressure head 4 can be detachably mounted on the other end of the rod-shaped spoon handle 1. The second spoon tail includes a connecting curved rod 6. The other end of the connecting curved rod 6 is provided with a longitudinal blade 5. The longitudinal blade 5 is triangular, and the lower end of the longitudinal blade 5 is sharpened. The longitudinal blade 5 is made of a smooth and hard material, and the blade arrangement direction is on the same plane as the rod-shaped spoon handle 1.
