Abstract
The utility model relates to a disposable blood collector which comprises a blood collecting needle, a vacuum blood collecting tube, a catheter and a rubber plug. The rubber plug is mounted on the vacuum blood collecting tube, the blood collecting needle is mounted on the rubber plug via the catheter, a film cannula is disposed on the rubber plug, the catheter penetrates through the film cannula arranged on the rubber plug to extend into the vacuum blood collecting tube, an end of the film cannula is divided into a plurality of strip-shaped structures along the axial direction of the cannula, and the strip-shaped structures are squeezed to the center of the film cannula and are sealed. A blood collection function and functions of a test tube are integrated, the disposable blood collector is simple in structure and convenient to use, blood is collected and examined in a completely sealed state, and cross infection and environmental pollution are avoided.
Description
Technical field
This utility model relates to a kind of disposable blood taking device, belongs to the medical appliance field.
Background technology
Blood test is an effective means of making a definite diagnosis the cause of disease, at present, mainly uses syringe and disposal vacuum volumetric hemostix as hemostix, and it is comparatively general that the former uses, and takes a blood sample with syringe earlier, is divided in vitro according to lab work again.The major defect of this hemostix is: pollution in transfer process, also cause simultaneously cross infection easily. the disposal vacuum volumetric hemostix, western countries use more, form by two-way pin of syringe sleeve and vacuum test tube; Or two-way pin of flexible pipe and vacuum test tube composition, during use, two-way pin one end penetrates vein blood vessel; The other end penetrates plug, forms the negative pressure blood drawing with the negative pressure of vacuum device, and the shortcoming of this hemostix is: blood sampling speed is slow, troublesome poeration; Two-way pin and needle stand sealing are difficult for seeing blood back, and needle tubing is thick, sleeve is shorter; Be difficult to accomplish that vein thrusts once success, and will vacuum test tube be compressed up during blood sampling, be easy to move the pin position; In addition, because Aisan's vascular is thinner, so be difficult in domestic applying.
Summary of the invention
This utility model technical problem to be solved provides a kind of disposable blood taking device, can avoid cross infection and environmental pollution, the strict disposable disposable epidemic prevention hemostix that prevents viral infection under the condition of sealing fully.
For addressing the above problem, this utility model adopts following technical scheme:
A kind of disposable blood taking device; Comprise blood taking needle, vacuum blood-collecting tube, conduit and rubber stopper, said rubber stopper is installed on the vacuum blood-collecting tube, and said blood taking needle is installed on the rubber stopper through conduit; It is characterized in that: said rubber stopper is provided with film casing; Said conduit passes the film casing that is arranged on the rubber stopper and extend in the vacuum blood-collecting tube, and the end of said film casing axially is divided into some list structures along pipe, and to center extruding and sealing.
This utility model compared with prior art has following characteristics: the hemostix that uses is at present compared, and blood sampling is combined as a whole with test tube; Simple in structure, easy to use, blood sampling and chemical examination under complete sealing state; Avoided cross infection and, can control the blood volume of collection simultaneously, avoided because of once gathering the not enough repeated acquisition that needs of blood volume to the pollution of environment; Can not cause confusion and cross infection, usage charges are low.
Below in conjunction with accompanying drawing and embodiment this utility model is described further:
Description of drawings
Accompanying drawing 1 is the structural representation of disposable blood taking device among this utility model embodiment.
Among the figure:
The 1-blood taking needle, 2-vacuum blood-collecting tube, 3-rubber stopper, 4-conduit, 5-film casing.
The specific embodiment
Embodiment, as shown in Figure 1, a kind of disposable blood taking device; Comprise blood taking needle 1, vacuum blood-collecting tube 2, conduit 4 and rubber stopper 3, said rubber stopper 3 is installed on the vacuum blood-collecting tube 2; Said blood taking needle 1 is installed on the rubber stopper 3 through conduit 4, and said rubber stopper 3 is provided with film casing 5, and said conduit 4 passes the film casing 5 that is arranged on the rubber stopper 3 and extend in the vacuum blood-collecting tube 2; The end of said film casing 5 axially is divided into some list structures along pipe, and to center extruding and sealing.
During use, blood taking needle 1 is inserted in the middle of the human body passages through which vital energy circulates, then conduit 4 is pushed to vacuum blood-collecting tube 2 gently; Make film casing 5 break away from the port of conduit 4, make blood taking needle, vacuum blood-collecting tube and conduit be communicated with, and form negative pressure between the human body; Utilize human bloodstream pressure simultaneously, make blood enter into vacuum blood-collecting tube 2, when gathering end; Conduit 4 is extracted from vacuum blood-collecting tube 2, and the end of film casing 5 axially is divided into some list structures along pipe, through the effect of power; To center extruding and sealing, make vacuum blood-collecting tube 2 seal.
