Description
Technical field
This utility model relates to medical apparatus and instruments, particularly the structure of quantitative trace blood pipet.
Background technology
Common tool when micro blood-taking tube and pipet are the medical department analyzing bloods such as hospital.This micro blood-taking tube by internal diameter less, both ends open and be communicated with glass tubing make, gather blood time by one end of micro blood-taking tube and contacting blood to be collected, utilize capillary theory, make blood to be collected automatically enter micro blood-taking tube inside.According to existing quantitative trace blood pipet, be by arranging and its passage communicated in the side, upper end of micro blood-taking tube.And the processing technique of above-mentioned quantitative trace blood pipet requires high, yield rate is low, so need to develop the simple quantitatively trace blood pipet of a kind of structure.
Summary of the invention
For above-mentioned the deficiencies in the prior art part, the problem that this utility model solves is: provide a kind of structure simple integrated quantitative trace blood pipet.
For solving the problem, the technical scheme that this utility model is taked is as follows:
A kind of integrated quantitative trace blood pipet, comprises air bag, reservoir, trachea and micro blood-taking tube; Described air bag lower end and the upper end of reservoir communicate; Described trachea is located at the below of air bag and the upper end of the upper end of trachea and reservoir communicates; Described micro blood-taking tube is fixed on the inside below trachea; Space is provided with between the lateral surface of described micro blood-taking tube and the inwall of trachea.
Further, the rectangular structure in bottom section of the inner chamber of described trachea; The rounded structure in outer lateral section of described micro blood-taking tube; The lateral surface of described micro blood-taking tube is separately fixed on four inwalls of trachea; Space is provided with between described micro blood-taking tube lateral surface and four right angle inwalls of trachea.
Further, the lateral surface of described micro blood-taking tube is adhesively fixed on four inwalls of trachea respectively by glue.
Further, described air bag lower end and the upper end of reservoir are communicated by a tubule; The diameter of described tubule is 1/1 to four/3rd of air bag and reservoir diameter.
Further, the upper end of described trachea and the upper end of reservoir are communicated by overflow pipe; Connection angle between described overflow pipe and trachea is less than or equal to 90 °.
Further, described micro blood-taking tube is glass tubing.
Further, described air bag is flat.
Further, described air bag is ellipsoid shape.
Further, described micro blood-taking tube is made up of hydrophilic high molecular material.
The beneficial effects of the utility model
1. this utility model by being provided with space thus instead of the breather line communicated in micro blood-taking tube upper end arranged outside between the lateral surface and the inwall of trachea of micro blood-taking tube.Structure of the present utility model is simple, simple and convenient processing method, and yield rate is high, manufactures efficiency and promotes at double.
2. the rectangular structure in the bottom section of the inner chamber of trachea of the present utility model, the rounded structure in outer lateral section of micro blood-taking tube, the lateral surface of micro blood-taking tube is separately fixed on four inwalls of trachea, is provided with space between micro blood-taking tube lateral surface and four right angle inwalls of trachea.Micro blood-taking tube and trachea are fixed cleverly by circular and rectangle tangent original, achieve again the object being provided with space between the lateral surface of micro blood-taking tube and the inwall of trachea, anatomical connectivity is rationally ingenious, stable connection.
3. the upper end of air bag lower end of the present utility model and reservoir is communicated by a tubule, and the diameter of tubule is 1/1 to four/3rd of air bag and reservoir diameter.Setting like this is convenient to control entering of liquid.
4. the upper end of trachea of the present utility model and the upper end of reservoir are communicated by overflow pipe, and the connection angle between overflow pipe and trachea is less than or equal to 90 °.The reflux problem can avoiding liquid in overflow pipe is so set.
