Abstract
The utility model provides a blood collecting tube. The blood collecting tube comprises a test tube and a combined cover which is used for sealing the test tube. The combined cover comprises a tube cover and a rubber plug which is arranged inside a cavity of the tube cover, and the tube cover and the rubber plug are formed integrally. The blood collecting tube has the advantages that due to the fact that the combined cover is adopted in the blood collecting tube to seal the test tube, and the tube cover of the combined cover and the rubber plug are formed integrally, compared with a structure that before the test tube is sealed, the rubber plug of the blood collecting tube and the tube cover need to be assembled, the structure of the blood collecting tube reduces processing procedure and lowers 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 blood taking tube, thereby increase the technical problem that manufacturing procedure improves production cost.
For achieving the above object, provide a kind of blood taking tube according to this utility model, comprised test tube and be used for the composite cover of sealing test tube, composite cover comprises the pipe lid and is arranged at pipe and cover plug in the cavity, pipe cover and plug 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: blood taking tube of the present utility model adopts composite cover to seal test tube, pipe lid and the plug of this composite cover are one-body molded, the plug of blood taking tube compared to existing technology and pipe covered before the sealing test tube needs to make up assembled construction, blood taking tube 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.
Description of drawings
The accompanying drawing that constitutes the application's a part is used to provide further understanding of the present utility model, and illustrative examples of the present utility model and explanation thereof are used for explaining this utility model, do not constitute improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the assembling sketch map of the blood taking tube of this utility model preferred embodiment;
Fig. 2 is the structural representation of the pipe lid of this utility model preferred embodiment; And
Fig. 3 is the structural representation of the composite cover of this utility model preferred embodiment.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated, but the multitude of different ways that this utility model can be defined by the claims and cover is implemented.
Referring to Fig. 1, this utility model provides a kind of blood taking tube, the composite cover 120 that it comprises test tube 3 and is used for sealing test tube 3.Wherein, composite cover 120 comprises that pipe cover 1 and be arranged at pipe and cover the interior plug 2 of 1 cavity, and the top of plug 2 is provided with groove 20, manages to cover 1 top and be provided with the hole 10 that is oppositely arranged with groove 20, and hole 10 is beneficial to blood taking needle and directly pierces through groove 20.The pipe cover 1 and plug 2 one-body molded.
Preferably, in process of production, pipe cover 1 with plug 2 employing double-shot moulding process formings; Particularly, will manage earlier and cover 1 one injection molded, and again plug 2 injection mouldings will be filled in pipe and cover in 1, form composite cover 120.
Referring to Fig. 2, pipe cover 1 inwall periphery and is provided with boss 11 and is positioned at pipe with formation and cover upper chamber 12 above 1 cavity, and boss 11 and managing covers between 1 the inwall and formed step surface 110.
In conjunction with Fig. 3, plug 2 comprises tight plug hat 21 of filling upper chamber 12, the plug neck 22 that plug hat 21 extension downwards and diameter diminish.Groove 20 is arranged at the top of plug hat 21, is beneficial to the blood taking needle puncture.The lower surface of plug hat 21 is closely against the step surface 110 of boss 11, has guaranteed the effect of upper chamber's 12 sealings.Leave between the periphery of plug neck 22 and the boss 11 and be beneficial to test tube 3 close-fitting gaps.When practical set, test tube 3 tightly fits in periphery and the gap between the boss 11 of plug neck 22, be easy to install and guaranteed test tube 3 and manage cover 1 and plug 2 between sealing effectiveness.For the ease of blood sampling, state generally is evacuated in the test tube 3.
In actual use, blood taking needle covers 1 hole 10 by pipe and pierce through plug 2 operation of taking a blood sample behind groove 20.
Blood taking tube of the present utility model adopts composite cover 120 to seal test tube 3, pipe lid 1 and the plug 2 of this composite cover 120 are one-body molded, the plug of blood taking tube compared to existing technology and pipe covered before the sealing test tube needs to make up assembled construction, blood taking tube of the present utility model has reduced manufacturing procedure, has reduced production cost.
The above is preferred embodiment of the present utility model only, is not limited to this utility model, and for a person skilled in the art, this utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
