Abstract

The utility model belongs to a medical appliance, and discloses a novel blood taking tube, which comprises a tube body, a rubber plug and a tube cap. An isolating cavity is arranged in the rubber plug, a groove is arranged on the outer wall of the rubber plug, a hook of a drag hook is located in the groove, and the tail end of the drag hook is fixedly connected with the tube cap. When the novel blood taking tube is used, negative pressure in the tube body is increased so as to guarantee smoothness during blood taking, and blood taking quantity can be sufficient. In addition, the novel blood taking tube is simple in structure, convenient in use and easy in manufacture, and has remarkable popularization significance.

Description

A kind of novel blood taking tube

Technical field

This utility model relates to field of medical article technology, relates to a kind of vacuum test tube that is used for gathering blood in particular.

Background technology

Vacuum test tube is a kind of novel hemostix commonly used.It is to utilize the intravital negative pressure of vacuum of pipe to draw blood, and with easy and simple to handle, safe and reliable, is each medical institutions' widespread usage.But in clinical use, find a little deficiency below the present vacuum test tube existence: after vacuum test tube was placed a period of time, negative pressure reduced to some extent in its vacuum chamber, and it is not smooth to cause blood to flow into, and influenced the suction volume of blood; Must change other blood taking tube again like the blood sample deficiency of finding extraction in the blood collection procedure and take a blood sample, certainly will bring some inconvenience to curative activity.

The utility model content

For overcoming above-mentioned technical problem, this utility model provides a kind of reasonable in design, with the preceding novel blood taking tube that increases the vacuum chamber negative pressure.

For realizing above-mentioned technical purpose, this utility model is to adopt following technical scheme to realize: a kind of novel blood taking tube comprises a body; The sealing of body one end, an end is through the plug sealing, and an end that seals through plug is with pipe cap; It is characterized in that: be provided with one in the plug and isolate cavity; The plug outer wall is provided with a groove, and the plug section diameter of the nearly mouth of pipe one side of groove is less, and keeps a gap between the inboard wall of tube body; Drag hook makes its hook portion be positioned at groove through this gap, and the drag hook tail end is fixedly connected with pipe cap.

The utlity model has following beneficial effect: before the use, pipe cap is extracted forward, because pipe cap links to each other with plug through drag hook; When extracting, pipe cap can drive the plug segment distance that moves forward; The intravital negative pressure of pipe is increased, and the smoothness during with the assurance blood sampling avoids blood sampling volume not enough; Be provided with separate cavities in the middle of the plug, the vacuum chamber and the external world isolate fully in the time of can guaranteeing blood taking needle puncture plug.It is simple in structure, and is easy to use, is easy to make, and has significant dissemination.

Description of drawings

Fig. 1 is the structural representation under this utility model unused state.

Structural representation after when Fig. 2 uses for this utility model pipe cap being extracted.

Among the figure, 1, body, 2, plug, 3, drag hook, 4, pipe cap, 5, isolate cavity, 6, groove, 7, the gap.

The specific embodiment

Referring to accompanying drawing 1,2, the sealing of body 1 one ends, an end is through plug 2 sealings, and body 1 is with pipe cap 4 through an end of plug 2 sealings; Be provided with one in the plug 2 and isolate cavity 5, the vacuum chamber and the external world isolate fully when guaranteeing blood taking needle puncture plug 2; Plug 2 outer walls are provided with a groove 6, and plug 2 section diameters of the groove 6 nearly mouth of pipe one sides are less, keep a gap 7 between this part and body 1 inwall, and drag hook 3 makes its hook portion be positioned at groove 6 through this gap 7, and drag hook 3 tail ends are fixedly connected with pipe cap 4.During use pipe cap 4 is extracted, pipe cap 4 drives plug 2 and moves to nose end, and when groove 6 moved to mouth of pipe place, drag hook 3 broke away from plug 2, and the reach of plug 2 has increased the negative pressure in the vacuum chamber, the fluency when having guaranteed blood sampling and enough blood sampling volumes.

Claims

1. a novel blood taking tube comprises a body, the sealing of body one end; One end is through the plug sealing, and an end that seals through plug is with pipe cap, it is characterized in that: be provided with one in the plug and isolate cavity; The plug outer wall is provided with a groove, and the plug section diameter of the nearly mouth of pipe one side of groove is less, and keeps a gap between the inboard wall of tube body; Drag hook makes its hook portion be positioned at groove through this gap, and the drag hook tail end is fixedly connected with pipe cap.
