Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to tumor specimen bags. Background Technology
[0002] Tumor specimen bags are transparent bags with a sealed structure made of medical-grade PVC or other biocompatible materials. They are medical sealed containers specifically designed for surgically removed tumor tissue, used to safely collect, fix, and transport specimens during or after surgery, ensuring the accuracy of pathological diagnosis.
[0003] However, existing tumor specimen bags have the following drawbacks:
[0004] (1) Existing tumor specimen bags have weak multi-layer leak prevention and real-time visual leak detection functions. Due to the accidental leakage of fixative, environmental pollution, personnel burns or instrument corrosion may occur.
[0005] (2) Existing tumor specimen bags have weak stability. Since there is no side support during the placement of the specimen bag, the specimen bag is prone to shifting or tipping over, which can easily damage the specimen. Utility Model Content
[0006] The purpose of this invention is to provide a tumor specimen bag to solve the problems mentioned in the background art.

[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. This tumor specimen bag, through the setting of the indicator component, allows for quick inspection of the specimen bag's rupture status. If the inner bag ruptures, liquid drips onto the second color-changing strip, causing it to change color. Simultaneously, the middle protective bag protects against leakage. If the middle protective bag ruptures, liquid drips onto the first color-changing strip, and the outer bag further prevents leakage. This allows personnel to quickly check the rupture status of the specimen bag. The valve allows liquid to be discharged from the specimen bag, and the sealing strip is a convex-concave buckle sealing strip, facilitating the closure of the specimen bag. This achieves multi-layered leak prevention and immediate visual leak detection, avoiding environmental pollution, personnel burns, or instrument corrosion caused by fixative leakage.
[0016] 2. This tumor specimen bag, through the setting of the support component, when in use, when the specimen bag is placed on a flat surface, the second and third folding strips are folded to form a triangle with the first folding strip, and then the bottom of the adhesive plate is attached to the top of the first folding strip, so that the child Velcro is connected to the mother Velcro. The third folding strip can support and limit the side of the specimen bag, preventing the specimen bag from shifting or tipping over. When carrying the device, the folding strips can be pulled into a straight line, so that the two sets of adhesive plates on the side of the specimen bag are attached, reducing the space occupied, thereby improving the stability of the specimen bag and avoiding the situation where the specimen bag is easily shifted or tipped over during the placement of the specimen bag without side support, which could easily damage the specimen.

[0028] The outer bag 201 is made of rigid PVC, while the inner bag 205 is made of soft PVC. Rigid PVC increases stability and prevents tipping, while soft PVC directly contains the tumor specimen and fixative, providing a strong seal.
[0029] The first folding strip 302, the second folding strip 303, and the third folding strip 304 are all made of stainless steel spring steel sheets. The stainless steel spring steel sheets allow the folding strips to fold together without breaking and also provide a certain degree of support.
[0030] In this invention, the working steps of the device are as follows:
[0031] First step: If the inner bag 205 breaks, the liquid drips onto the second color-changing strip 204, causing the second color-changing strip 204 to change color. At the same time, the middle protective bag 203 provides protection to prevent liquid leakage. If the middle protective bag 203 breaks, the liquid drips onto the first color-changing strip 202, and the outer bag 201 prevents liquid leakage again, making it convenient for personnel to quickly check the breakage of the specimen bag. The valve 206 can discharge the liquid in the specimen bag. The sealing strip 207 is a convex and concave buckle sealing strip 207, which makes it easy to close the specimen bag.
[0032] The second step: When the specimen bag is placed on a flat surface, fold the second folding strip 303 and the third folding strip 304 to form a triangle with the first folding strip 302. Then, attach the bottom of the bonding plate 305 to the top of the first folding strip 302, so that the child hook and loop fastener 306 is connected to the mother hook and loop fastener 307. The third folding strip 304 can support and limit the side of the specimen bag to prevent the specimen bag from shifting or tipping over. When carrying the device, the folding strip can be pulled into a straight line so that the two sets of bonding plates 305 on the side of the specimen bag are attached to reduce the space occupied.
[0033] The third step: The rectangular slot 4 connects and fixes the mother Velcro 307 to the first folding strip 302. The label frame 5 can hold the specimen information label and is waterproof. The surface is a transparent film. The scale markings 6 can easily control the amount of fixative added to avoid waste. The cotton thread with color-changing silicone will change color when it comes into contact with formaldehyde, and the leakage warning is visible to the naked eye. The rigid PVC increases stability and prevents tipping. The soft PVC directly contains the tumor specimen and fixative, with strong sealing. The stainless steel spring steel sheet can fold between the folding strips without breaking and has a certain degree of support.
