Description
Technical field
This utility model relates to technical field of medical instruments, particularly relates to a kind of negative pressure blood-taking tube rubber stopper.
Background technology
At medical field, blood taking tube is widely used, in order to make blood sample not reveal after acquisition, not contaminated, and most Basic practice seals blood sampling spout with plug.At present, the rubber plug for vacutainer be widely adopted mainly fills in face and plunger section composition, plunger blocks with the blood taking tube mouth of pipe and is connected, plug face need be punctured injection when taking a blood sample, and this kind of rubber plug for vacutainer there is plunger and blood taking tube connection sealing is poor, and a large amount of dust is infected with in plug face, when puncture injection, collecting sample is easily contaminated,, often there is blood taking tube landing when blood sampling operates in blood taking tube smooth surface simultaneously, causes certain difficulty to operation.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and provide a kind of negative pressure blood-taking tube rubber stopper, plug good airproof performance, friction effect is good, handled easily, is polluted when effectively prevent blood sampling.
This utility model is achieved through the following technical solutions: a kind of negative pressure blood-taking tube rubber stopper, comprise the upper cock body of end connection and lower cock body, described upper cock body is up big and down small conically shaped body, and several ring grooves are set on the beveled cone shape face of upper cock body, the surface of described lower cock body is be with gradient taper surface, the lower surface of described lower cock body arranges plug mouth, the glue head blocked with blood taking tube ferrule is provided with in described plug mouth, the round side of described glue head is connected slot with being formed between plug mouth, and the side surface of described glue head arranges two circle sealing rings.
Further, described plug body central arranges circular groove body, and the notch of described circular groove body arranges membrane layer.
Further, described plug mouth connects blood taking tube, and the upper port of blood taking tube be connected slot tight clamping fit.
Further, the bottom of described glue head arranges round recessed.
Compared with prior art, the beneficial effects of the utility model are: this utility model is by becoming to be with gradient taper surface by the lower cock body surface design be connected with blood taking tube, two circle sealing rings are set at the side surface of plug mouth hose lining head simultaneously, effectively utilize the elasticity of rubber, improve the sealing that rubber stopper is connected with blood taking tube, plug good airproof performance, upper cock body is designed to up big and down small conically shaped body simultaneously, and several ring grooves are set on the beveled cone shape face of upper cock body, add the friction effect of rubber stopper, facilitate and take operation, and membrane layer is set at the circular groove body notch of plug body central, polluted when effectively prevent blood sampling.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of negative pressure blood-taking tube rubber stopper of this utility model;
Fig. 2 is the structural representation that this utility model rubber stopper connects blood taking tube;
Fig. 3 is the top view of this utility model rubber stopper.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain this utility model, and be not used in restriction this utility model.
As Figure 1-3, this utility model relates to a kind of negative pressure blood-taking tube rubber stopper, comprise the upper cock body 6 of end connection and lower cock body 1, described upper cock body 6 is up big and down small conically shaped body, and several ring grooves 5 are set on the beveled cone shape face 4 of upper cock body 6, the surface of described lower cock body 1 is be with gradient taper surface 15, the lower surface of described lower cock body 1 arranges plug mouth 14, the glue head 8 blocked with blood taking tube ferrule is provided with in described plug mouth 14, the round side of described glue head 8 is connected slot 9 with being formed between plug mouth 14, the side surface of described glue head 8 arranges two circle sealing rings 12, described cock body 6 center arranges circular groove body 3, the notch of described circular groove body 3 arranges membrane layer 5, described plug mouth 14 connects blood taking tube 16, and the upper port of blood taking tube 16 be connected slot 9 tight clamping fit, the bottom of described glue head 8 arranges round recessed 13.
In sum, this utility model is by becoming to be with gradient taper surface 15 by lower cock body 1 surface design be connected with blood taking tube, two circle sealing rings 12 are set at the side surface of plug mouth 14 hose lining head 8 simultaneously, effectively utilize the elasticity of rubber, improve the sealing that rubber stopper is connected with blood taking tube, plug good airproof performance, upper cock body 6 is designed to up big and down small conically shaped body simultaneously, and several ring grooves 5 are set on the beveled cone shape face 4 of upper cock body 6, add the friction effect of rubber stopper, facilitate and take operation, and membrane layer 5 is set at circular groove body 3 notch at upper cock body 6 center, polluted when effectively prevent blood sampling.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
