Abstract
A disposable blood collector comprises a needle (2) and a tube connected to the bottom end of the needle, and the tube is a spiral tube (1). A need cap (3) is arranged on the periphery of the needle (2). Two to ten thread rings are arranged on the spiral tube (1). The disposable blood collector can generate larger negative pressure, is easier for blood drawing and collection, facilitates extrusion and control for the tube, and additionally can effectively protect the needle from pollution and protects the needle.
Description
Technical field
This utility model relates to a kind of blood sampling medical apparatus and instruments, is specifically related to a kind of disposable blood taking device.
Background technology
Checking clinically with blood preparation generally is to extract with disposable syringe, when extracting blood preparation, also must prepare equipment such as test tube, pipe close, also increased the probability of sterilization number of packages and bacterial infection when having wasted resource, and because checkout procedure need be changed apparatus for placing with blood preparation, so might cause certain error to assay.
The Chinese patent publication number is CN201299574, open day is that 2 days utility model description of JIUYUE in 2009 discloses " disposable blood taking device ", this utility model comprises body, it is characterized in that being provided with neck on described body top, on described neck, be provided with needle stand, on described needle stand, be provided with syringe needle, be provided with groove at described body and neck junction, compared with prior art, this utility model has easy to use, clean hygiene, characteristics such as probability are infected in reduction.But this utility model is in extruding during body, the bad grasp of control dynamics, and the negative pressure of formation is smaller, and blood drawing is difficulty relatively.
The utility model content
The purpose of this utility model is deficiencies such as the negative pressure of pushing body difficulty, formation at existing disposable blood taking device is little, blood drawing difficulty, and big, the labour-saving disposable blood taking device of drawing blood of negative pressure of a kind of convenient extruding body, formation is provided.
The purpose of this utility model realizes by following technological means: a kind of disposable blood taking device, and include syringe needle and be connected the body that is provided with its bottom, described body is set to serpentine pipe.
The periphery of described syringe needle also is provided with the pin medicated cap.
Described serpentine pipe is provided with 2-10 screw thread circle.
Compared with prior art the utlity model has following tangible advantage: this disposable blood taking device can form bigger negative pressure, and the blood sampling of drawing blood has more easily made things convenient for extruding body and control body; In addition, can effectively protect the not contaminated and protection syringe needle of syringe needle.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure, 1-serpentine pipe, 2-syringe needle, 3-pin medicated cap.
The specific embodiment
Below in conjunction with the description of drawings and the specific embodiment this utility model is described in further detail:
A kind of disposable blood taking device as shown in Figure 1 includes syringe needle 2 and is connected the body that is provided with its bottom, and described body is set to serpentine pipe 1.Described serpentine pipe 1 is provided with 2-10 screw thread circle.Be provided with like this, this disposable blood taking device in use can be by the serpentine pipe 1 of 2-10 screw thread circle of extruding, more can form bigger negative pressure, the blood sampling of drawing blood has more easily made things convenient for extruding body and control body, has improved result of use of the present utility model.
The periphery of described syringe needle 2 also is provided with pin medicated cap 3.Be provided with like this, this disposable blood taking device can effectively protect syringe needle 2 not be not damaged by the pollution of external environment and protection syringe needle 2.
This disposable blood taking device in use, hand serpentine pipe 1 is discharged gas, just is in negative pressure state in the serpentine pipe 1, syringe needle 2 is thrust in the blood vessel, extract syringe needle 2 after making blood flow in the serpentine pipe 1, then the threaded portion of top in the serpentine pipe 1 is cut, serpentine pipe 1 promptly can be used as the test tube censorship.
In a word, this utility model provides big, the labour-saving disposable blood taking device of drawing blood of negative pressure of a kind of convenient extruding body, formation.The above; it only is a part of specific embodiment of the present utility model; protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that this utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.
