A limiting frame is movably sleeved outside the outer bag and below the sealing strip. A through groove is opened inside the limiting frame and outside the outer bag. A threaded groove is opened on one side of the limiting frame. A screw rod is threadedly connected inside the threaded groove. One end of the screw rod extends into the through groove and is connected with a clamping plate through a shaft sleeve. One side of the outer bag is fixedly connected with a connecting head, and one end of the connecting head extends into the inner bag.
[0005] Preferably, soft pads are arranged on one side of the clamping plate close to the outer bag and on one side of the inner cavity of the through groove close to the outer bag.

[0010] The utility model provides a double-layer leak-proof specimen bag, which has the following beneficial effects:
[0011] 1. For this double-layer leak-proof specimen bag, by providing an outer bag, an inner bag and a connector, when it is necessary to pump formalin solution into the inner bag, the operator unscrews the threaded sleeve from the outside of the connector, so that the sealing plug is located outside the connector. Then, one end of the equipment pipeline for pumping formalin solution is inserted into the inner bag through the connector, and then formalin solution is pumped into the inner bag. After adding formalin solution into the inner bag, one end of the equipment pipeline for pumping formalin solution is pulled out from the inside of the connector, and then the threaded sleeve is screwed on the outside of the connector, so that one end of the sealing plug is inserted into the connector. Through the design of the inner and outer double bags, the risk of specimen leakage can be reduced. By inserting one end of the equipment pipeline for pumping formalin solution into the inner bag through the connector, it can prevent the solution from leaking when pouring the solution.
[0012] 2. For this double-layer leak-proof specimen bag, by providing a limit frame, a screw rod and a clamping plate, the outer bag can be sealed through a sealing strip. Then, the top end of the outer bag is folded over. Then, the limit frame is sleeved outside the folded part at the top end of the outer bag through a through groove. Then, the operator rotates the screw rod, so that the screw rod pushes the clamping plate to move, and the clamping plate clamps the folded part of the outer bag, enhancing the leak-proof ability of this specimen bag. When the sealing strip fails to seal, the top end of the outer bag can be clamped through the limit frame and the clamping plate to prevent the solution in the specimen bag from leaking.
