The invention discloses a disposable vacuum blood taking tube comprising a test tube (1), a rubber plug (2) and a head cap (3). The rubber plug (2) is plugged tightly on a tube mouth of the test tube (1), and the head cap (3) is sleeved outside the plug rubber (2). A connecting device (7) fixedly connected with the head cap (3) and the test tube (1) is arranged on one side of the head cap (3), and can enable the head cap (3) to turn around the connecting device (7). The disposable vacuum blood taking tube has the advantages that integrated and movable connection between the head cap and the test tube is realized through the arrangement of the connecting device, force required by opening is reduced, opening process is stable and smooth, spill of samples can be effectively avoided, and operation safety is improved; the disposable vacuum blood taking tube can be opened and covered with a single hand, and application difficulty is reduced; the rubber plug is still fixed on the head cap after the disposable vacuum blood taking tube is opened, and is not required to be placed individually, so that contamination and loss of the rubber plug are avoided; the disposable vacuum blood taking tube is convenient to operate, and working efficiency of medical workers is improved; and the size of the rubber plug is greatly reduced as compared with that of an existing blood taking tube, and production cost is reduced.
Description
Technical field
The present invention relates to technical field of medical instruments, particularly disposable use vacuum test tube.
Background technology
The vacuum blood collection Manifold technology is present international advanced blood collecting technology.The vacuum test tube technical characterstic is: (1) automatic gauge, and need not pumpback: because the people can control blood sampling volume by controlling air pressure for causing vacuum in the blood taking tube.Need not artificial pumpback metering when operation.(2) aseptic degree height, check is disturbed little: be vacuum in the holding tube, vacuum test tube mouthpiece cover seal is better, aseptic degree height, the blood contamination probability is little, and is less relatively to the interference of assay.(3) once annotate blood and go into pipe, it is little that blood constituent changes: the vacuum blood collection method is directly injected blood taking tube with blood, omitted blood in injector syringe stop and be transferred to two processes of blood taking tube from syringe, reduced the extruding repeatedly of blood, cytoclasis is few, and assay is more reliable.
Existing vacuum test tube mainly is made up of test tube, rubber stopper and head cap, and the rubber stopper jam-pack is used for the plug for seal test tube at the test tube mouth of pipe, and head cap is sleeved on the rubber stopper, and vacuum is pumped in test tube body inside, and its inside is added with relevant blood additive.In the time of rubber stopper need being separated with body, firmly head cap is separated with test tube, rely on the frictional force between head cap and the rubber stopper, rubber stopper is separated with test tube, but because rubber stopper cooperates tightlyer with test tube, test tube is negative pressure, and rubber stopper is softer, rubber stopper is difficult to separate with test tube, and operator need could extract rubber stopper with bigger power from the test tube mouth of pipe.Operator control head cap cover or rubber stopper for convenience, and also in order to increase be used to the frictional force of extracting rubber stopper, existing rubber stopper all needs to be processed into larger volume, thereby has increased production cost.When rubber stopper separated from the test tube mouth of pipe, because firmly bigger, test tube and rubber stopper all had instantaneous displacement, cause the blood sample in the test tube to spill, and operator are caused infection; Simultaneously owing to firmly more also may cause the test tube mouth of pipe to break.Rubber stopper need be placed during collected specimens, thereby may cause pollution and the loss of rubber stopper, have potential safety hazard and operation inconvenience.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, the safe disposable use vacuum test tube that a kind of opening process is stable gently, reduce operation easier, operation is provided.
Purpose of the present invention is achieved through the following technical solutions: disposable use vacuum test tube, it comprises test tube, jam-pack at the rubber stopper of the test tube mouth of pipe and is set in the head cap of rubber stopper outside, and a side of head cap is provided with all fixedlys connected with test tube with head cap and make head cap around the connecting device of its upset.
Described rubber stopper comprises the column type plug neck of bottom and is arranged at the column type plug edge on plug neck top that fill in neck and the test tube mouth of pipe and closely cooperate, head cap is set in the outside on plug edge.
Described head cap is positioned at the opposite side relative with the side that connecting device is set and is provided with the lid eaves that protrudes from the head cap outer wall.
Described connecting device is for flexibly connecting sheet, and an end that flexibly connects sheet is fixedlyed connected with the test tube body, and the flexible other end is in flakes fixedlyed connected with head cap.
Described connecting device is to be fixedly arranged on otic placode A with holes on the head cap, to be fixedly arranged on otic placode B with holes and connecting axle on the test tube, and otic placode A and otic placode B are hinged by connecting axle.
The described additive that in vitro is equipped with in advance.
The present invention has the following advantages: the present invention realizes that by connecting device is set the one of head cap and test tube flexibly connects, when opening rubber stopper, only need upwards to promote to cover eaves, rubber stopper and head cap are that fulcrum rotates with the connecting device place, compare rubber stopper and the test tube of existing blood taking tube and do linear relative movement, have reduced and have opened required exerting oneself, there is not instantaneous unexpected displacement, opening process is stable more mild, has effectively prevented spilling of sample, has improved the safety of operation; Because having reduced, the present invention opens firmly, and head cap is connected by connecting device with test tube, and therefore, the present invention can open, cover by one hand, reduced the use difficulty, open the back rubber stopper and still be fixed on the head cap, do not need independent placement, prevented pollution and the loss of rubber stopper, in the time of need covering, finger is pressed and got final product, and is easy to operate, improved medical personnel's work efficiency; The present invention is by promoting to cover the unlatching that eaves is realized rubber stopper, the parts that need control when rubber stopper does not need conduct to open, it only is used for the capping test tube, therefore, compare existing blood taking tube structure and reduced the volume of rubber stopper greatly, thereby reduced the manufacturing cost of blood taking tube.
