Abstract
The utility model relates to an amnion freeze drying bracket which adopts the technical scheme that the amnion freeze drying bracket comprises a freeze drying frame, a freeze drying bench, an blank-holding bar and a dust cover. A rectangular hole and a plurality of positioning holes are formed on the freeze drying frame; the freeze drying bench is inserted in the rectangular hole and divided into an upper layer and a lower layer, wherein the dimension of the upper layer is larger than that of the rectangular hole, the dimension of the lower layer is smaller than that of the rectangular hole, and the thickness of the lower layer is larger than that of the freeze drying bracket; positioning columns projecting downwards are mounted on two sides of the edge pressing rod and correspond to the positioning hole on the freeze drying bracket; the edge pressing strip is connected with the periphery of the freeze drying bench; and the dust cover is connected with the freeze drying bench and the edge pressing rod. The utility model can ensure that the plane shape of amnion is unchanged during the freeze drying; and in addition, because the heat transfer rate of stainless steel materials is quick, the temperature rising and reducing rate of the amnion can be accurately controlled during the freeze drying.
Description
Technical field
The invention relates to the freeze-drying carriage that uses in a kind of freeze-drying amnion production process.
Background technology
The amnion of human body is the innermost layer of placenta, is a kind of clinical widely used biological implantation material, is widely used in ophthalmology and the operation.Freeze drying amnion (being called for short the freeze-drying amnion) is a kind of amnion slice material that conveniently uses and preserve.
In traditional amnion freeze-dry process, the operator places freeze drying on the sheet glass with amnion.Because of amnion lacks mechanical constraint in freeze-drying process, so the easy flexural deformation of amnion influences finished product state; Slow because of the glass material heat-transfer rate in addition, so the warming and cooling rate of amnion is difficult to control in the freeze-drying process.
Summary of the invention
In order to overcome the above problems, the invention provides a kind of amnion freeze-drying carriage, makes amnion keep flat shape constant in freeze-drying process; In addition fast because of the stainless steel material heat-transfer rate, can make that the warming and cooling rate of amnion is able to accurate control in the freeze-drying process.
To achieve these goals, the technical scheme of the invention employing is: a kind of amnion freeze-drying carriage comprises freeze-drying frame, freeze-drying platform, edge-pressing strip and dust cap; Have rectangular opening and several locating holes on the freeze-drying frame; The freeze-drying platform inserts in the rectangular opening, and the freeze-drying platform is divided into two-layer up and down, and the upper strata size is greater than rectangular opening, and lower floor's size is less than rectangular opening, and lower thickness is greater than the thickness of freeze-drying frame; The reference column to lower convexity is equipped with in the edge-pressing strip both sides, and reference column is corresponding with the locating hole on the freeze-drying frame, and edge-pressing strip is connected all around with the freeze-drying platform; Dust cap is connected with edge-pressing strip with the freeze-drying platform.
Freeze-drying frame, freeze-drying platform, edge-pressing strip and dust cap adopt stainless steel.
The beneficial effect of the invention is: in the invention, the freeze-drying carriage can be fixed in amnion wherein, and amnion is difficult for producing deformation in the process of freeze-drying; The freeze-drying carriage is a stainless steel, and heat-transfer rate is fast, and can high-temperature sterilization, meets the medicine equipment production requirement; The freeze-drying carriage has dust cap, can avoid contamination by dust when being transferred in the freeze dryer between amnion is by preliminary treatment.

Fig. 2 is the decomposition texture schematic diagram of the invention.
The specific embodiment
Also in conjunction with the accompanying drawings the invention is described in further detail below by specific embodiment.
Embodiment one
As depicted in figs. 1 and 2, a kind of amnion freeze-drying carriage comprises freeze-drying frame 1, freeze-drying platform 2, edge-pressing strip 3, dust cap 4.
Freeze-drying frame 1 has several locating holes 6 above for the middle rectangle corrosion resistant plate that has rectangular opening 5, is respectively applied for fixedly freeze-drying frame 1 and edge-pressing strip 3, and freeze-drying frame 1 both sides jug is with convenient hand-held; Freeze-drying platform 2 inserts in the rectangular opening 5, freeze-drying platform 2 is the stainless steel polyhedron, be divided into two-layer up and down, two-layerly up and down be flat rectangular structure, the upper strata size is slightly larger than the rectangular opening 5 at freeze-drying frame center, is the amnion overlay planes, and lower floor's undersized is in the rectangular opening at freeze-drying frame center, be used to contact sample disc in the freeze dryer, lower floor's cube thickness is slightly larger than freeze-drying frame steel plate thickness; Edge-pressing strip is the cuboid piece of stainless steel, and the cylindrical reference column 7 to lower convexity is equipped with in both sides, and reference column 7 is corresponding with the locating hole 6 on the freeze-drying frame 1, and edge-pressing strip 3 is connected all around with freeze-drying platform 2; Dust cap 4 is the rectangle corrosion resistant plate, and dust cap 4 is connected with edge-pressing strip 3 with freeze-drying platform 2, is used to prevent that dust from entering.
During use, the freeze-drying frame is positioned on the operating desk,, amnion is placed on the freeze-drying platform, launch and cleaning being placed under the freeze-drying platform in the freeze-drying frame central rectangular aperture; After treating that amnion fully launches, edge-pressing strip is fixed in around the freeze-drying platform, guarantees that reference column inserts in the locating hole; After leaving standstill 30 minutes, cover dust cap; Send into freeze-drying in the freeze dryer.
Claims (1)
