Connection device of replaceable sealing phlegm suction tube

Abstract

The invention relates to a connection device of a replaceable sealing phlegm suction tube. A connection device body is provided with a connection part; the connection part is provided with a connection base; the top edge and the bottom edge of the connection base respectively form opposite track grooves and a phlegm suction tube joint which is connected to the connection base, is communicated with the connection part, is provided with a joint fastener combined with the track grooves of the connection base and a replaceable sealing base separately sheathed to the connection part of the body; the front side surface of the replaceable sealing base is level with the front side surface of the connection base; the periphery of a sealing surface, which is provided with the replaceable sealing base, forms the track groove communicated relative to the track groove on the connection base; and the replaceable sealing base is convexly provided with a sheathed groove which is sheathed and contained on the connection part so as to form a connection device capable of conveniently replacing the phlegm suction tube group.

Description

technical field [0001] The invention relates to a connection device, in particular to a connection device of a replaceable closed sputum suction tube. Background technique [0002] The closed sputum suction tube is different from the general open sputum suction tube. It is a breathing tube that does not need to be removed from the patient. It can maintain the patient's breathing while pumping sputum, reducing the impact on the patient's vital signs ( vital sign), and can prevent the occurrence of respiratory tract infection or cross infection in the hospital during the sputum extraction process. However, when it is desired to replace a new sputum suction tube group, the current replaceable sputum suction tube cannot avoid the problem of sputum outflow because there is no sealing structure between the tube bodies. Contact with the outflowing sputum can cause infection or cross infection in the hospital. In addition, most of the existing replaceable sputum suction tubes are c...

Problems solved by technology

However, when it is desired to replace a new sputum suction tube group, the current replaceable sputum suction tube cannot avoid the problem of sputum outflow because there is no sealing structure between the tube bodies. Contact with the outflowing sputum can cause infection or cross infection in the hospital. In addition, most of the existing replaceable sputum suction tubes are combined with other components by thread or rotary coupling devices, so in disassembly or assembly, It must be rotated many times to untie the combination of threads, so it is troublesome and inconvenient to operate. Therefore, the existing sputum suction tube has its shortcomings in structure and use.
