The utility model adopts the technical proposal that: the manual dialyzer switch comprises a dialyzer and a blood pipeline, wherein a blood inlet connected with the blood pipeline is formed in the dialyzer, the dialyzer also comprises a base, a first connector connected with the blood pipeline and a second connector connected with the blood inlet are respectively arranged on two opposite sides of the base, a blood channel is arranged in the base in a penetrating manner, and the first connector is communicated with the second connector through the blood channel; a first sliding chute is horizontally arranged in the base, a sliding sheet capable of opening and closing a blood channel is movably arranged in the first sliding chute, and the sliding sheet is connected with a sliding handle through a connecting rod; the base is provided with a second sliding groove used for sliding of the connecting rod, and the second sliding groove is communicated with the first sliding groove. When blood pipeline need be dismantled, slide handle drive gleitbretter slides in first spout through sliding, shelters from the blood passageway at first gleitbretter completely after, realizes the choked flow of blood in the blood passageway, also namely closes the blood passageway, then accomplishes the dismantlement of blood pipeline again. The dialyzer switch of the utility model prevents the blood in the dialyzer from overflowing to the external environment through the blood inlet, thereby ensuring the cleanness of the external environment and medical care personnel and simultaneously reducing the risk of blood disease cross infection; the device has simple structure, convenient operation and low cost.
Furthermore, the base is a cuboid, so that the production process is simpler and more convenient, the components on the base can be better arranged, and the base is small in size.
Further, the surfaces of the two sides of the sliding piece are provided with sealing gaskets, the sealing performance of the sliding piece and the first sliding groove is improved, and blood is prevented from overflowing from the surface of the sliding piece.
Further, the length of second spout matches with the diameter of blood passageway, when the slip handle slides two extreme position of second spout, corresponds blood passageway complete closure promptly and opens two kinds of states completely to the open and close state of blood passageway is known more directly perceivedly to the medical personnel of being convenient for.
Further, the sliding handle is a cylinder, and compared with the square structure, the arrangement of edges and corners is reduced, so that the sliding handle is smoother, and the comfort level of the sliding handle is improved.
Furthermore, the first connector is in threaded connection with the blood pipeline, so that the connection is firmer, and the disassembly and the assembly are more convenient and quick.
Furthermore, the second connector is connected with the blood inlet through threads, so that the connection is firmer, and the disassembly and the assembly are more convenient and quick.
The utility model has the advantages that: when the blood pipeline is disassembled, the manual dialyzer switch can prevent the blood in the dialyzer from overflowing to the external environment through the blood inlet, thereby ensuring the cleanness of the external environment and medical care personnel and simultaneously reducing the risk of cross infection of blood diseases; the device has simple structure, convenient operation and low cost.
