Abstract
The utility model discloses a disposable micro hemostix comprising a blood tube (1), a gas-controlling casing (3) and a connector (2); wherein the blood tube is sleeve-jointed the gas-controlling casing through the connector. A gas-controlling gasbag (4) are arranged on one end of the gas-controlling casing (3); the blood tube (1) is capillary with an inner diameter (the diameter of inner wall) less than or equal to 1.5mm. As the capacity of the blood tube is determined beforehand, self-controlled and quantitative blood sampling can be realized by self-priming principle of the capillary. The utility model has the advantages of ingenious design, rational structure and convenient use.
Description
Technical field
This utility model relates to a kind of medical hemostix, particularly a kind of disposable use trace blood device.
Background technology
Traditional hemostix that medical institutions use generally is a syringe, and its major defect is that blood sampling volume can't quantitatively be controlled, and is easy to cause the blood waste; And complex operation, and give and to accept blood sampling person and cause suffering.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existing procucts, and a kind of disposable use trace blood device is provided.It can automatic control, quantitatively blood sampling.
The purpose of this utility model can reach by following measure: a kind of disposable use trace blood device, by blood taking tube (1), gas-control bushing (3) and the adapter (2) that is used for they are connected together constitute, end at gas-control bushing (3) is equipped with a gas-control bag (4), described blood taking tube (1) is a capillary tube, and its internal diameter (inside pipe wall diameter) is less than or equal to 1.5 millimeters.
The utlity model has following characteristics: the capacity of blood taking tube is pre-determined, utilizes the capillary imbibition principle to realize that automatic control quantitatively takes a blood sample, and designs ingenious, rational in infrastructure, easy to use.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Further specify this utility model below in conjunction with accompanying drawing.
As shown in Figure 1, this utility model is by blood taking tube 1, and gas-control bushing 3 and the adapter 2 that is used for they are connected together constitute, and at an end of gas-control bushing 3 gas-control bag 4 is installed.Described blood taking tube 1 is disposable capillary tube, and its specification can be divided into 10 microlitres, 20 microlitres, 40 microlitres etc., and its internal diameter (inside pipe wall diameter) is less than or equal to 1.5 millimeters.The material of blood taking tube 1 can be that borosilicate system or sodium silicon are glass.Described gas-control bushing 3 is reusable, and its material can be medical macromolecular materials.Described gas-control bag 4 can be latex make air bag.Described adapter 2 is generally plastic.Be connected in belled mode between the gas-control bushing 3 of adapter 2 and the blood taking tube 1 and the other end, can be arbitrarily affixed or pull up.
During use, blood taking tube 1 one ends submerge in the blood, suitably adjust the hemostix angle, and blood unimpededly sucks in the body from the tube head freedom.Extruding gas-control bag 4 is discharged blood.
