[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a specimen leakage prevention device, including a bottle cap 1 for closing a suction bottle, the bottle cap 1 is a prior art and can be implemented by a person skilled in the art. Due to the prior art, this case will not be described in detail. The top of the bottle cap 1 is penetrated and installed with a delivery tube 2 for delivering the patient's body fluid, and the bottom end of the delivery tube 2 is provided with a fixing component 3 for fixing a filter component 4, and the fixing component 3 includes a fixing sleeve 32 for connecting the bottom end opening of the delivery tube 2, and the fixing sleeve 32 is sleeved on the bottom end of the delivery tube 2. The fixing sleeve 32 The bottom end of the filter housing 31 is fixedly connected with a fixed shell 31 for connecting a fixed sleeve 32 and a filter sleeve 41. The bottom end of the fixed shell 31 is provided with a filter component 4 for filtering the patient's body fluid. The filter component 4 includes a connecting ring 42 for connecting the filter sleeve 41 and the fixed shell 31. The connecting ring 42 is plugged into the bottom end of the fixed shell 31. The bottom end of the connecting ring 42 is fixedly connected with a filter sleeve 41 for filtering body fluid. The filter sleeve 41 is made of fine and soft metal mesh material, which can achieve a filtering effect, is not easily damaged, and can be repeatedly used after cleaning.

[0030] Reference Figure 1 - Figure 3The inner wall of the fixing sleeve 32 is fixedly connected with a rubber pad 33 for increasing the sealing performance, the front end of the fixing sleeve 32 is fixedly connected with a fixing box 34 for accommodating the buckle 35, the front end of the fixing box 34 passes through and is slidably connected with a buckle 35 for fixing the fixing sleeve 32, and the bottom end of the bottle cap 1 is provided with a slot 37 for accommodating the buckle 35, the slot 37 and the buckle 35 are adapted, when the buckle 35 is inserted into the inside of the slot 37, the top end of the fixing sleeve 32 will be fixed to the bottom end of the bottle cap 1, the thickness of the buckle 35 is fixedly connected with a fixing spring 36 for supporting the buckle 35, the rear end of the fixing spring 36 is fixedly connected to the inner wall of the fixing box 34, and the fixing spring 36 will always push the buckle 35 forward.

[0031] Reference Figure 1 - Figure 3 The front end of the fixed shell 31 is fixedly connected with a connecting box 45 for accommodating a connecting block 46, and the rear end of the connecting box 45 passes through and is slidably connected with a connecting block 46 for fixing the connecting ring 42. The connecting block 46 passes through and slides on the outer wall of the fixed shell 31, and the bottom end of the connecting block 46 is provided with an inclined surface. When the connecting block 46 is squeezed upward, it will be forced to move outward. The outer wall of the connecting ring 42 is provided with an annular groove 44 for accommodating the connecting block 46, and the annular groove 44 and the connecting block 46 are adapted. When the connecting block 46 is inserted into the inside of the annular groove 44, the connecting ring 42 will be fixed to the bottom end of the fixed shell 31. At this time, the connecting ring 42 can rotate, but cannot be separated from the bottom end of the fixed shell 31. The front end of the connecting block 46 is fixedly connected with a connecting spring 47 for pushing the connecting block 46. The front end of the connecting spring 47 is fixedly connected to the inner wall of the connecting box 45, and the connecting spring 47 will always push the connecting block 46 backward so that it cannot be separated from the annular groove 44 at will.

[0032] Reference Figure 1 - Figure 3 The top of the connecting block 46 is fixedly connected with a cylindrical block 48 for driving the connecting block 46 to move. The cylindrical block 48 penetrates and slides on the top of the connecting box 45. The connecting block 46 can be driven to move forward by shifting the cylindrical block 48 forward. The outer wall of the fixed shell 31 is rotatably connected with a convex ring 49 for squeezing the cylindrical block 48. The outer wall of the convex ring 49 is fixedly connected with a shifting block 410 for facilitating the operator to rotate the convex ring 49. The convex ring 49 can be driven to rotate by rotating the shifting block 410. When the convex ring 49 rotates, it squeezes the cylindrical block 48 to move it outward. The top of the connecting ring 42 is fixedly connected with a sealing ring 43 for increasing the tightness of the connection between the fixed shell 31 and the connecting ring 42. The top of the sealing ring 43 is set to an inclined surface. By using the inclined surface of the top of the sealing ring 43 to squeeze the inclined surface of the bottom end of the connecting block 46, the connecting block 46 can be forced to move outward.

[0033] Working principle: when filtering is required, the whole device can be moved to the bottom end of the bottle cap 1 first, and then the fixed sleeve 32 can be moved upward to be sleeved on the outer wall of the bottom end of the conveying tube 2. When moving, the top of the buckle 35 needs to be aligned with the bottom end of the slot 37 until the top of the fixed sleeve 32 contacts the bottom end of the bottle cap 1, and the buckle 35 will also be inserted into the inside of the slot 37. Then the fixed shell 31 can be loosened. At this time, the whole device will be fixed at the bottom end of the bottle cap 1, and then the device can be used to filter the specimen. When the specimen needs to be removed, the dial block 410 can be rotated first to drive the convex ring 49 to rotate. When the convex ring 49 rotates, it will squeeze the cylindrical block 48 to make it move outward. The cylindrical block 48 will drive the connecting block 46 to move outward to disengage from the annular groove 44. Then the filter sleeve 41 can be moved downward to remove the specimen inside it.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
