Abstract
The utility model discloses a disposable vacuum blood collection tube which comprises a test tube (1), a rubber plug (2) tightly plugged at the mouth of the test tube (1), and a head cap (3) sleeved outside the rubber plug (2). One side of the head cap (3) is provided with a connecting device (7) which is fixedly connected with the head cap (3) and the test tube (1) and enables the head cap (3) to turn around the connecting device (7). The disposable vacuum blood collection tube has the advantages of realizing integrated movable connection of the head cap and the test tube through the arrangement of the connecting device so as to reduce opening force, be stable in opening process, effectively prevent samples from splashing, and improve the safety of operation; being capable of being opened and closed by one hand so as to reduce utilization difficulty; preventing pollution and loss of the rubber plug due to the fact that the rubber plug is still fixed on the head cap after being opened and does not need placing independently; being convenient to operate so as to improve the working efficiency of medical workers; greatly reducing the size of the rubber plug compared with an existing blood collecting tube structure so as to reduce manufacturing cost.
Description
Technical field
This utility model 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 is high, and check is disturbed little: be vacuum in the holding tube, vacuum test tube mouthpiece cover seal is better, and aseptic degree is high, and the blood contamination probability is little, to the interference less of assay.(3) once annotate blood and enter 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 repeatedly extruding of blood, cytoclasis is few, and assay is more reliable.
Existing vacuum test tube mainly is comprised 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 to 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 to could extract rubber stopper with larger power from the test tube mouth of pipe.For the handled easily personnel control head cap cover or rubber stopper, 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 larger, 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 to be placed during collected specimens, thereby may cause pollution and the loss of rubber stopper, have potential safety hazard and operation inconvenience.
The utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, and the safe disposable use vacuum test tube that a kind of opening process is stable gently, reduce operation easier, operation is provided.
The purpose of this utility model 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 head cap and all is fixedly connected with and makes head cap around the connecting device of its upset with test tube.
Described rubber stopper comprises the column type plug neck and the column type plug edge that is arranged at plug neck top of bottom, 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 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 fixedly connected with the test tube body, and the flexible other end in flakes is fixedly 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 preinstalled with.
The utlity model has following advantage: this utility model realizes that by connecting device is set the one of head cap and test tube is flexibly connected, when opening rubber stopper, only need upwards to promote to cover eaves, rubber stopper and head cap rotate take the connecting device place as fulcrum, 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 more stable mild, has effectively prevented spilling of sample, has improved the safety of operation; Because having reduced, opens firmly this utility model, and head cap is connected by connecting device with test tube, and therefore, this utility model can be opened, cover by one hand, reduced the use difficulty, open rear 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 to covering, finger is pressed and got final product, and is easy to operate, improved medical personnel's work efficiency; This utility model is by promoting to cover the unlatching that eaves is realized rubber stopper, the parts that need to 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 greatly reduced the volume of rubber stopper, thereby reduced the manufacturing cost of blood taking tube.
