Abstract
The utility model provides a combination tube cap which is used for sealing a test tube of a blood collection tube. The combination tube cap comprises a tube cap body and a rubber plug arranged in a cavity of the tube cap body. The tube cap body and the rubber plug are integrally formed. According to the combination tube cap, the tube cap body and the rubber plug are integrally formed, and compared with a structure in the prior art that a rubber plug and a tube cap body of a combination tube cap need to be combined and assembled before the test tube is sealed, the combination tube cap provided by the utility model reduces processing procedures and lowers production cost.
Description
Technical field
This utility model relates to medical instruments field, especially, relates to a kind of compound tube lid for the sealed vacuum blood taking tube.
Background technology
Existing compound tube lid for the sealed vacuum blood taking tube, its plug and the preparation respectively of pipe lid seal the blood taking tube that is configured for gathering blood with test tube after plug is assembled together with Guan Gai again.The compound tube lid of this structure, its plug and pipe covered before the sealing test tube needs combination to be assembled together, thereby has increased manufacturing procedure, has improved production cost.
The utility model content
This utility model purpose is to provide a kind of blood taking tube, covers before the sealing test tube and need combination assemble with plug and the pipe that solves existing compound tube lid, thereby increase the technical problem that manufacturing procedure improves production cost.
For achieving the above object, provide a kind of compound tube lid according to this utility model, for the test tube of sealing blood taking tube, it comprises that pipe covers and is arranged at pipe and covers the interior plug of cavity, and pipe lid and plug are one-body molded.
Further, the top of plug is provided with groove, and the top of pipe lid is provided with the hole, and hole and groove are oppositely arranged.
Further, the inwall periphery of pipe tegmental wall is provided with boss and is positioned at the upper chamber of managing tegmental wall cavity top with formation, forms step surface between the inwall of boss and pipe tegmental wall; Plug comprises the plug hat, and the plug hat is filled in upper chamber, and the lower surface of plug hat is butted on step surface.
Further, plug also comprises along filling in the plug neck that hat extends and diameter diminishes downwards, leaves the gap between the periphery of plug neck and the boss.
The utlity model has following beneficial effect: compound tube lid of the present utility model, its pipe lid and plug are one-body molded, the plug of compound tube lid compared to existing technology and pipe covered before the sealing test tube and need to make up assembled construction, composite cover of the present utility model has reduced manufacturing procedure, has reduced production cost.
Except purpose described above, feature and advantage, this utility model also has other purpose, feature and advantage.With reference to figure, this utility model is described in further detail below.
