Abstract

Provided is a micro blood collection tube. The micro blood collection tube is characterized by being composed of a pressing head and a siphon. The outer diameter of the pressing head is smaller than the inner diameter of the siphon, the pressing head is arranged in the siphon, and a hole is formed in the side wall of the siphon. The micro blood collection tube is reasonable in design. The structure of combining the pressing head and the blood collection tube is adopted, the pressing head replaces a traditional rubber head, the pressing head and the blood collection tube are arranged integrally, and therefore the micro blood collection tube is convenient to use, and the blood collection tube does not need to be inserted into the rubber head manually. Common materials are adopted in the micro blood collection tube so that the micro blood collection tube is low in manufacturing cost. Meanwhile, the micro blood collection tube is a disposable blood collection device, thereby being safe and clean. According to the micro blood collection tube, cross contamination and infection on medical workers can be avoided, shortcomings of original products are overcome, and the micro blood collection tube is a further innovation to a traditional micro blood collection tube.

Description

The trace blood pipe

Technical field

This utility model relates to a kind of medical apparatus, especially a kind of trace blood pipe.

Background technology

After existing trace blood pipe sucks whole blood by siphon, must artificially insert the matching gel head by hand, push and get.This blood taking tube is complex operation in use, when inserting the matching gel head, because blood unskilled or that carelessness is easy to have sucked discharges, exists blood to enter the probability of glue head and pollutes, and influences the result or the medical worker is produced harm.

Summary of the invention

In order to overcome the blood taking tube complex operation, to the demanding technical problem of operator's maneuver, the mode that this patent adopts press head and siphon to combine.

The technical scheme that its technical problem that solves this utility model adopts is: a kind of trace blood pipe is characterized in that be made of press head and siphon, the external diameter of press head places in the siphon less than siphonal internal diameter, on the siphon sidewall hole is set.

The beneficial effects of the utility model are: reasonable in design, utilize press head and blood taking tube structure combining, and press head has replaced traditional glue head, makes press head and blood taking tube place one, is easy to use, and need not artificially blood taking tube be inserted in the glue head.Adopt common used material, cheap, be disposable lancing device, safety and sanitation have been avoided cross-contamination and to medical worker's infection, have been overcome the shortcoming of existing product, are the further innovations to traditional trace blood pipe.

Description of drawings

Fig. 1 is the structural representation of trace blood pipe;

Fig. 2 is to use the sketch map of method.

Among the figure: 1, press head; 2, hole; 3, siphon; 4, blood.

The specific embodiment

Below in conjunction with example this patent is further described.

The rainbow blood collection method is as shown in Figure 2:

(1) siphon head is immersed the blood sampling point;

(2) because the siphon sidewall has hole, can suck blood voluntarily by siphon;

(3) use the thumb press press head, blood is discharged.

Claims (1)

1. a trace blood pipe is characterized in that, is made of press head (1) and siphon (3), and the external diameter of press head (1) places in the siphon (3) less than the internal diameter of siphon (3), on siphon (3) sidewall hole (2) is set.
