Description
Technical field
The present invention relates to technical field of medical instruments, particularly single use vacuum test tube.
Background technology
Vacuum blood collection Manifold technology is the blood collecting technology of international advanced person at present.Vacuum test tube technical characterstic is: (1) automatic gauge, need not pumpback: because people in blood taking tube is for causing vacuum, controls blood sampling volume by controlling air pressure.Need not the artificial pumpback metering when operating.(2) sterility is high, and inspection interference is little: be vacuum in holding tube, and vacuum test tube mouthpiece cover seal is better, and sterility is high, and blood contamination probability is little, relatively little to the interference of assay.(3) once note blood and enter pipe, blood constituent changes little: blood is directly injected blood taking tube by Vacuum tube blood collection, eliminates the stop of blood in injector syringe and is transferred to blood taking tube two processes from syringe, decreasing the extruding repeatedly of blood, cytoclasis is few, and assay is more reliable.
Existing vacuum test tube is primarily of test tube, rubber stopper and head cap composition, and rubber stopper jam-pack is used for plug for seal test tube at the test tube mouth of pipe, and head cap is sleeved on rubber stopper, and test tube tubular body is pumped into vacuum, and its inside is added with relevant blood additive.When needing rubber stopper to be separated with body, firmly head cap is separated with test tube, rely on the frictional force between head cap and rubber stopper, rubber stopper is separated with test tube, but because rubber stopper coordinates comparatively tight with test tube, test tube is negative pressure, and rubber stopper is softer, rubber stopper and test tube are difficult to be separated, and operator need rubber stopper to be extracted from the test tube mouth of pipe by larger power.Conveniently operator hold head cap cover or rubber stopper, and also in order to increase the frictional force for extracting rubber stopper, existing rubber stopper all needs to be processed into larger volume, thus adds production cost.When rubber stopper is separated from the test tube mouth of pipe, due to firmly comparatively large, test tube and rubber stopper all have instantaneous displacement, cause the blood sample in test tube to spill, cause infection to operator; Simultaneously owing to firmly the test tube mouth of pipe also may be caused to break comparatively greatly.Need rubber stopper to place during collected specimens, thus pollution and the loss of rubber stopper may be caused, there is potential safety hazard and operation inconvenience.
Summary of the invention
The object of the invention is to the shortcoming overcoming prior art, provide a kind of opening process to stablize gently, reduce operation easier, single use vacuum test tube that the safety of operation is high.
Object of the present invention is achieved through the following technical solutions: single use vacuum test tube, it comprise test tube, jam-pack the test tube mouth of pipe rubber stopper and be set in the head cap of rubber stopper outside, the side of head cap is provided with and is all fixedly connected with test tube with head cap and makes the connecting device that head cap overturns around it.
Described rubber stopper comprises the column type plug neck of bottom and is arranged at the column type plug edge on plug neck top, and plug neck and the test tube mouth of pipe closely cooperate, and head cap is set in the outside on plug edge.
Described head cap is positioned at the opposite side relative with the side arranging connecting device and is provided with the lid eaves protruding from head cap outer wall.
Described connecting device is for flexibly connecting sheet, and the one end flexibly connecting sheet is fixedly connected with test tube body, and the flexible other end is in flakes fixedly connected with head cap.
Described connecting device is the otic placode A with holes be fixedly arranged on head cap, be fixedly arranged on otic placode B with holes on test tube and connecting axle, and otic placode A and otic placode B is hinged by connecting axle.
Described is in vitro preinstalled with additive.
The present invention has the following advantages: the present invention realizes head cap be flexibly connected with the one of test tube by arranging connecting device, when opening rubber stopper, only need upwardly lid eaves, rubber stopper and head cap rotate for fulcrum with connecting device place, and rubber stopper and the test tube of comparing existing blood taking tube do linear relative movement, reduce and open required exerting oneself, there is not instantaneous unexpected displacement, opening process is more stable mild, effectively prevent spilling of sample, improves the safety of operation; Open firmly owing to present invention reduces, and head cap is connected by connecting device with test tube, therefore, the present invention can open, covers by one hand, reduce use difficulty, open rear rubber stopper to be still fixed on head cap, do not need independent placement, prevent pollution and the loss of rubber stopper, when needing to cover, finger is pressed, easy to operate, improves the work efficiency of medical personnel; The present invention realizes the unlatching of rubber stopper by promoting lid eaves, rubber stopper does not need the parts held as needs when opening, and it is only for capping test tube, therefore, compare the volume that existing blood taking tube structure substantially reduces rubber stopper, thus reduce the manufacturing cost of blood taking tube.
