Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of specimen bags, in particular to a specimen bag used for fixing lung tissue specimens. Background Art
[0002] With the widespread development of molecular testing for lung cancer and the increasing use of targeted drugs in clinical practice, pathology testing is placing increasingly higher demands on specimen quality. Standardized tissue pretreatment is a prerequisite for ensuring specimen quality, and adequate specimen fixation is particularly important. Insufficient specimen fixation will affect routine HE staining, as well as subsequent immunohistochemistry and molecular testing. Because lung tissue is filled with a large amount of gas, it tends to float to the top of the fixative during fixation, resulting in inadequate fixation of the lung tissue. The tissue specimen bags currently used by pathology departments cannot solve the problem of floating lung tissue specimens during fixation.
[0003] The main solutions to the inadequate fixation of lung tissue in existing specimen tapes are: 1. Covering the lung tissue with absorbent cotton, but there is a risk of the absorbent cotton slipping during fixation; 2. After adding fixative to the specimen bag, manually expel as much remaining air as possible from the specimen bag to create a vacuum. Although this method can increase the area of lung tissue exposed to the fixative, it still makes it difficult to fully fix the upper lung tissue; 3. Instilling formaldehyde fixative through the lung bronchi can ensure sufficient contact between lung tissue and the fixative, but it is not suitable for lung wedge resection specimens and the operation is relatively complex, requiring a high level of technical skill.
[0004] It can be seen that the above solutions all have their own drawbacks, so a specimen bag for fixing lung tissue specimens is proposed to solve the above problems. Utility Model Content
[0005] (1) Technical problems solved
[0006] In response to the shortcomings of the existing technology, the utility model provides a specimen bag for fixing lung tissue specimens. It has the advantages of simple operation, no need for special equipment, easier promotion and application in pathology departments of grassroots units, broad market application prospects, and good economic value. It solves the problem that the tissue specimen bags currently used by pathology departments cannot solve the floating problem of lung tissue specimens when fixed.
[0007] (2) Technical solution
[0008] The utility model provides a technical solution to the above-mentioned technical problem as follows: a specimen bag for fixing lung tissue specimens, comprising a specimen bag, wherein a first attached ear is provided on the left side of the specimen bag, and a second attached ear is provided on the right side of the specimen bag and is symmetrically distributed front to back. The second attached ear on the rear side is movably connected to a drawstring passing through the first attached ear and the second attached ear on the front side, and the outer sides of both ends of the drawstring are provided with the same drawstring fixing buckle.
[0009] The beneficial effects of the utility model are:
[0010] The specimen bag for fixing lung tissue specimens allows the lung tissue to be suspended below the drawstring in the specimen bag filled with fixative solution by tightening the drawstring, thereby ensuring sufficient fixation of the specimen without squeezing the lung tissue. The invention is simple to operate, does not require special equipment, is easier to promote and apply in pathology departments of grassroots units, has broad market application prospects, and has the advantages of good economic value.
[0011] On the basis of the above technical solution, the present invention can also be improved as follows.
[0012] Furthermore, the first attached ear and the second attached ear are connected to the left and right side edges of the specimen bag by welding.
[0013] The beneficial effect of adopting the above further solution is that the first attached ear and the second attached ear are connected to the specimen bag in a welding manner, so that the first attached ear and the second attached ear can be firmly fixed to both sides of the specimen bag.
[0014] Furthermore, through holes for passing the drawstring are formed on the surfaces of the first attachment ear and the second attachment ear.
[0015] The beneficial effect of adopting the above further solution is that the through holes on the surfaces of the first attached ear and the second attached ear are used for passing the drawstring. BRIEF DESCRIPTION OF THE DRAWINGS
