And the maximum spacing 15mm of first connecting portion 110 and 120 internal and external threads of second connecting portion, it is ensured that sealing mantle 130 is always
Encase the part interconnected of first connecting portion 110 Yu second connecting portion 120.
It is understood that in other embodiments, which can also not contain the sealing mantle 130, phase
The separation membrane infusion connector 100 answered can be applied in sterile, ultra-clean medical environment.
The first diaphragm 112 is equipped in the first connecting portion 110 of above-mentioned separation membrane infusion connector 100, second connecting portion 120 is set
There is the second diaphragm 122, and when first connecting portion 110 is packed into second connecting portion 120, the first diaphragm 112 and the second diaphragm 122
Composition can be cooperated to completely enclose the diaphragm of the liquid-transport pipe-line of the separation membrane infusion connector 100, thus at the end of infusion, operation
Person only needs routinely using external infusion connector is extracted after the washing pipes liquid such as physiological saline or heparin, then by first connecting portion 110 to
Second connecting portion 120 packs into, and such as packs into 5mm, and the first diaphragm 112 and the second diaphragm 122 is made to cooperate completely enclosed liquid-transport pipe-line, this
When, positive pressure can be automatically generated in the separation membrane infusion connector 100, the source of positive pressure is that first connecting portion 110 is connected to second
When portion 120 packs into squeeze liquid generate positive pressure (size of pressure be long 5mm, diameter 8.4mm cylindrical body volume just
Pressure), tube-sealing solution positive pressure tube sealing need not be reused at this time and uses hemostatic clamp, so that it may when effectively eliminating the extraction of external infusion connector
The negative pressure of generation, and effective positive pressure is formed in liquid-transport pipe-line.When needing to be infused, as long as operator is by first connecting portion
110 to 120 sets of second connecting portion from such as covering from 5mm, separate the first diaphragm 112 with the second diaphragm 122, liquid-transport pipe-line is led
Logical, at this point, will form the negative pressure of equivalent in liquid-transport pipe-line, (size of pressure is the body of the cylindrical body of long 5mm, diameter 8.4mm
Long-pending negative pressure), negative pressure can automatically cause endovascular blood backflow (i.e. clinically " blood back ") after generating.The generation of " blood back "
The operator indwelling needle tubing can be explicitly indicated still in the blood vessels, thus operator do not need again it is raw by pumpback blood or preliminary filling
The methods of salt water is managed whether in the blood vessels to judge the indwelling needle tubing, the cumbersome monitoring of operator can be effectively reduced, effectively mentioned
High working efficiency reduces the waste of consumptive material.
100 structure of separation membrane infusion connector is simple, easy to operate, and the hair of remaining needle plugging phenomenon can be effectively prevented
It is raw.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
The embodiments described above only express several embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously
It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that coming for those of ordinary skill in the art
It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to protection of the invention
Range.Therefore, the scope of protection of the patent of the invention shall be subject to the appended claims.
