Description
Technical field
This utility model relates to and is used for sealing-plug, is specifically related to a kind of blood taking tube with the anti-plug of raising one's hat of splashproof, belongs to technical field of medical instruments.
Background technology
In medical field, the health that blood sample is checked human body need be gathered usually by medical institutions.Traditional blood collection method is first syringe blood drawing, the blood tuberculosis in the syringe is inspected by ready samples in test tube again.Blood easily causes pollution in the tuberculosis process, influence the accuracy of testing result; Whole blood collection procedure complexity of while, the lost labor.Under this background, easy and simple to handle and blood sample is difficult for contaminated being widely used because of it for negative pressure blood taking tube or vacuum test tube.Negative pressure blood taking tube or vacuum test tube mainly are made up of blood taking tube body, plug and block, have certain negative pressure or vacuum in the body.During blood sampling, an end of blood taking needle punctures into the blood vessel of human body, subsequently the plug of the other end puncture blood collecting pipe of blood taking needle; Because the blood in negative pressure or the vacuum condition in the pipe, human vas flows into blood taking tube.Here, plug plays the effect of sealing, and block plays and prevents that plug when unpacking blood sample from splashing operator's effect; Plug and block have constituted a kind of compound cap stopper.But, break away from each other easily between the block of this compound cap stopper and the plug, so operator are still inevitable by the situation of blood contamination.Though there is multiple mode to improve connectivity robustness between block and the plug at present, be that the Chinese patent of CN2614628Y has been set up the plug bizet of a protruding circle to stop that the plug upper diameter is bigger such as: grant number on the inside of block.But block and plug are assembled after all producing respectively again, so the production of combination type plug needs one injection moulding, one mold pressing procedure and one assembling procedure at least, and production process is loaded down with trivial details.Therefore, the rubber plug for vacutainer of integral type has advantage aspect the simplification production process at least than combination type plug.Such as, grant number be in the Chinese patent of CN2022883300U disclosed a kind of blood taking tube with the anti-plug of raising one's hat, this plug has been set up the annular extension of surrounding the plug cervical region, this annular extension and other parts of plug are integrated, its production technology is simple, only need one mold pressing procedure can finish manufacturing, and the normal accident of raising one's hat that occurs in the compound cap stopper can not occur.But this blood taking tube is still waiting to improve aspect the safety of operators realizing how preventing in the blood taking tube that blood sample spills even splashes with the anti-plug of raising one's hat.
The utility model content
This utility model technical issues that need to address are to overcome the deficiencies in the prior art, provide a kind of blood taking tube to prevent raising one's hat plug with splashproof, this plug can not only be avoided the normal accident of raising one's hat that occurs in the compound cap stopper, can also prevent that blood sample splashes operator in the moment of plug unpacking in the blood taking tube, the safety in utilization of this plug improves greatly.
This utility model technical issues that need to address are achieved through the following technical solutions:
A kind of blood taking tube comprises the plug cervical region, is positioned at plug cervical region top and covers the plug bizet of plug cervical region and the annular extension that links to each other with the plug bizet with the anti-plug of raising one's hat of splashproof; The annular extension is extended to plug cervical region direction by the plug bizet, and the internal cavity of annular extension surrounds the plug cervical region; Plane, the lower end wall place certain distance of the lower end wall extend through plug cervical region of annular extension, and this distance is 1/3 to 5 times of plug cervical region height.Even being arranged so that when breaking seal plug of this distance has blood sample to spill, the blood sample that spills also can be blocked by the annular extension of plug, has guaranteed that blood sample can not splash operator.
Optimized technical scheme can be: described plug outer wall is provided with anti-skid structure.The hands that favourable increase operator are set of anti-skid structure and the frictional force between the rubber plug for vacutainer make operator's clamping blood taking tube more firm.
Further optimized technical scheme can be: the lower surface of described plug cervical region and its outer wall junction are provided with chamfering, and the lower surface of described annular extension and its inwall junction are provided with chamfering.Chamfering structure makes the plug and the assembling of blood sampling body become easy.
Further optimized technical scheme can be: the place, below that the inwall of described annular extension is positioned at described plug cervical region is provided with flange.Because plug made by elastomeric material, the coefficient of friction between the blood taking tube body of itself and plastic material is big; By flange is set, both can be more firmly fixing blood taking tube body, can reduce again the unpacking plug the resistance that must overcome.
Further optimized technical scheme can be: the upper surface of described plug bizet is provided with inner groovy.Inner groovy be provided with the dynamic airtightness that helps realize plug, also can reduce to a certain extent in addition blood taking needle puncture plug the path of process, make that the puncture plug is more smooth.
Compared with prior art, advantage of the present utility model and beneficial effect are: this blood taking tube is an integral structure with the anti-plug of raising one's hat of splashproof, can avoid making up the situation generation that plug is raised one's hat; Simultaneously, by the planar distance in place, lower surface that the annular extension that links to each other with the plug bizet is extended the cervical region of leaving the boundary is set, can realize preventing that blood sample in the blood taking tube from splashing operator's effect in the moment that plug is broken seal; This plug is simple in structure, and is easy to manufacture and easy to use.
