Abstract
The utility model relates to the medical apparatus and instruments, and particularly to improvement of a micro-scale blood collection tube. The self-suction type quantified micro-scale blood collection tube comprises a through micro-tube with two open ends and a hollow extruding air bag with an open end, wherein the micro-tube is made of a hydrophilic material; one end of the micro-tube is inserted and fixed in an end port of the air bag; the inner cavity of the micro-tube is communicated with an inner cavity of the air bag; and a vent hole communicated to the inner cavity of the air bag is formed in the wall of the air bag. The self-suction type quantified micro-scale blood collection tube is low in cost as no hydrophilic treatment is necessary, is easy in generalization, and improves accuracy and efficiency of a blood collection process greatly.
Description
Technical field:
This utility model relates to medical apparatus and instruments, relates in particular to the improvement of trace blood pipe.
Background technology:
The trace blood pipe is the common tool that medical department such as hospital is gathered blood, this trace blood pipe is less by internal diameter, the glass tubing of both ends open and connection is made, end with the trace blood pipe when gathering blood contacts with blood to be collected, utilize capillary theory, make blood to be collected enter trace blood pipe inside automatically, the requirement of capacity is generally arranged when gathering blood, is marked with containing mark at the trace blood pipe, as 5 microlitres, 10 microlitres, 15 microlitres, 20 microlitres ..., 50 microlitres.Because it is very fast to treat that blood sampling enters the speed of trace blood pipe, the medical worker often has little time to remove the trace blood pipe when blood arrives on the scale that needs, cause actual blood sampling volume greater than the blood sampling volume of needs, thereby during the blood in taking out the trace blood pipe, not only need the trace blood pipe is inserted in the red water dropper of latex, the red water dropper of reuse finger extruding latex, just can shift out the blood in the trace blood pipe, and to control the amount of taking-up, long and inaccuracy of whole process time spent, also inconvenient, the U.S. one medical apparatus and instruments merchant has produced a kind of self-priming trace blood pipe that is made of plastics, trace blood pipe and squeezable air bag are become as a whole during fabrication, and the assigned scale place on the trace blood tube wall is provided with passage, when blood arrives assigned scale, blood is namely blocked passage, make capillarity stop, blood no longer enters the trace blood pipe, thereby finish quantitative trace blood, reuse finger extruding gasbag can take out blood, the whole blood process of getting is accurate, fast, convenient, but because this self-priming trace blood pipe is made of plastics, the trace blood inside pipe wall has hydrophobicity, be not easy capillarity takes place and suck blood, so will carry out hydrophilic during fabrication to the inwall of plastics trace blood pipe handles, this process time spent is longer, production efficiency is very low, increase product cost greatly, hindered applying of self-priming trace blood pipe.At present do not need the self-priming quantitative trace blood Guan Shangwei cheaply that carries out hydrophilic treated to see.
The utility model content:
At the above-mentioned deficiency of existing in prior technology, technical problem to be solved in the utility model is that a kind of self-priming quantitative trace blood pipe will be provided, and it does not need to carry out hydrophilic treated, and cost is low, is easy to promote, and improves accuracy and the efficient of blood collection procedure greatly.
In order to solve the problems of the technologies described above, the scheme of this utility model technical solution problem is: self-priming quantitative trace blood pipe, comprise the trace blood pipe of both ends open and connection and the squeezable air bag of an end opening and hollow, described trace blood pipe is made by water wetted material, one end of described trace blood pipe is inserted and secured in the port of described air bag, and the inner chamber of described trace blood pipe is communicated with the inner chamber of described air bag, has the passage that is communicated with this air bag inner chamber on the wall of described air bag.
After adopting such scheme, because described trace blood pipe is made by water wetted material, one end of described trace blood pipe is inserted and secured in the port of described air bag, and the inner chamber of described trace blood pipe is communicated with the inner chamber of described air bag, have the passage that is communicated with this air bag inner chamber on the described air bag, thereby the trace blood pipe contacts with blood capillarity can take place, and treats that blood sampling can be easy to enter the trace blood pipe.When taking out the blood in the trace blood pipe, get final product with passage and the extruding gasbag pointed on the wall of blocking air bag, on the other hand, air bag and trace blood pipe cost are very little, easy to utilize, improve efficient and the convenience of use greatly.
The cross-sectional area of trace blood tube cavity and the product of length are the volume of trace blood pipe, (the trace blood pipe is generally pipe suitably to choose the internal diameter of trace blood pipe and length, the cross-sectional area of its inner chamber is determined by internal diameter), can make the trace blood pipe of various capacity specifications.As 5 microlitres, 10 microlitres, 15 microlitres, 20 microlitres ..., 50 microlitres etc.
The inwall of the outer wall of described trace blood pipe and air bag port sticks with glue to connect and is fixed together.
Described air bag is flat.Fixing with finger when being convenient to operate.
Described air bag is the ellipsoid shape.Fixing with finger when being convenient to operate.
Described passage is arranged on the end of described air bag,
Described passage is arranged on the utricule of described air bag, and finger can be blocked passage easily during extruding gasbag.
Described trace blood pipe is made by glass.
Described trace blood pipe is made by hydrophilic high molecular material.
Description of drawings:
Below in conjunction with the drawings and specific embodiments the self-priming quantitative trace blood pipe of this utility model is further described,
Fig. 1 is the structural principle sketch map of the self-priming quantitative trace blood pipe embodiment of this utility model.
The specific embodiment:
Among Fig. 1, self-priming quantitative trace blood pipe comprises the trace blood pipe (2) of glass of both ends open and connection and the squeezable air bag (1) of an end opening and hollow, trace blood pipe (2) is made by glass, one end of trace blood pipe (2) is inserted and secured in the port of air bag (1), and the inner chamber (3) of trace blood pipe (2) is communicated with the inner chamber (5) of air bag (1), has the passage (4) that is communicated with the inner chamber (5) of this air bag (1) on the wall of air bag (1).Finger can be blocked ventilation (4) hole easily during extruding gasbag.The inwall of the outer wall of trace blood pipe (2) and air bag (1) port sticks with glue to connect and is fixed together.Air bag (1) is flat, and is fixing with finger when being convenient to operate.
