Detailed Description

The technical solution of the present invention is further described in detail by the following specific examples.

It should be noted that the present embodiment is merely an explanation of the present invention, and is not a limitation of the present invention. Any changes that may be made by one skilled in the art after reading the specification of the invention are, within the scope of the claims, protected by the patent laws.

Example 1:

a filter protector for clinical negative pressure suction equipment is mainly used for preventing sucked liquid moisture from flowing back to the negative pressure suction equipment to damage the equipment, and the structure of the filter protector is shown in figures 1, 2, 3 and 4, and comprises a first protection piece 10 and a second protection piece 20 which are made of medical plastic materials. The first protection piece 10 and the second protection piece 20 are cylindrical, the outer sides (the sides far away from each other) of the first protection piece and the second protection piece are provided with connectors 101 used for being connected with suction tubes, the structure of each connector 101 adopts a tube body connector 101 in the existing medical equipment, and the connection tightness and the connection firmness can be guaranteed. The first protection piece 10 and the second protection piece 20 are connected through threads, a filtering protection space is formed between the first protection piece and the second protection piece, the interior of the connector 101 is communicated with the filtering protection space, a water absorption expansion net piece 30 is arranged in the filtering protection space, and the size of the net hole is 50 meshes. An annular clamping groove 102 is formed in the inner wall of the first protection piece 10, and the water-absorbing expansion net piece 30 is placed in the clamping groove 102 for fixing. The water-absorbing expansion net sheet 30 adopts water-absorbing resin, and is quickly converted into gel after absorbing water to realize water resistance. The filtering protector is a disposable medical appliance and can be replaced once the filtering protector enters water.
