Abstract
The utility model discloses a disposable aseptic transfusion system, including a intravenous injection needle (15), a catheter, a flow display (2), a flow regulating switch (4), an air-compensating tube, a liquid-feeding needle (9) and so on; the device is characterized in that the liquid-feeding needle (9) is set to be the needle body with the air-feeding porous channel (6) and the liquid-discharging porous channel (7); one end of the needles is the needlepoint; the air outlet of the compensated air (10) is arranged at the needlepoint; the part near the other end of the needle body is provided with a protruding table (13) in the radial direction; the hole (14) of the protruding table (13) is communicated with the air-feeding porous channel (6); one side of the needlepoint near the protruding table (13) is provided with the liquid inlet (8); the liquid inlet (8) is communicated with the liquid-discharging porous channel (7). In the utility model, because the compensated air does not pass through the medical liquid, the device reduces the pollution of the bacteria in the air to the medical liquid; moreover, the transfusion bottle has no changes and can be repeatedly used after being disinfected.
Description
Technical field:
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of disposable sterilized transfusion device.
Background technology:
As everyone knows, the disposable transfusion device of hospital's use at present, the structure of employing is that a pin connects tube for transfusion, and another root pin connects additional trachea, and make-up gas enters in the bottle by medicinal liquid, owing to contain antibacterial in the air medicinal liquid in the bottle is had certain contamination.Though also there is the people studying and addressing this problem, as 97205636X multifunctional transfusion bottle in order to address this problem, infusion bottle is designed on the bottle downside wall default porose, is filled with the yarn bag of band disinfecting drug in the hole, behind the disinfecting drug of packing into, the outside is sealed with glass sintering earlier, during transfusion, infusion bottle is inverted, is knocked out the outer close mouth of bottle downside wall air inlet, air can not produce the phenomenon of air by medicinal liquid at the bottom of just can directly entering bottle from this.But this technical scheme still exists the medicinal liquid bottle can only use once, can not reuse, and causes the defective of the rising of transfusion cost and the wasting of resources.
The utility model content:
The purpose of this utility model is to overcome the deficiencies in the prior art and a kind of transfusion cost that provides rises lessly, does not waste resource, reduces in the air antibacterial to a kind of disposable sterilized transfusion device of the pollution of medicinal liquid.Concrete technical scheme is: disposable sterilized transfusion device is made up of intravenous needle, conduit, flow indicator, flow control valve, replenish air pipe, feed liquor pin etc., the feed liquor pin is designed to bring into the needle body in pore road and fluid duct, one end of needle body is a needle point, the make-up gas gas outlet is positioned at needle tip, the other end close end of needle body radially is provided with a boss, hole in the boss communicates with the air inlet duct, and needle point one side is provided with inlet by the boss place, and inlet communicates with the fluid duct.
For ease of carrying comparatively heavy-gravity medicinal liquid, can set up an aerating gasbag and air inlet adjustment switch in additional trachea end.
Transfuse blood for ease of dosing mouth, can behind flow indicator, set up a flow control valve from flow indicator.
When using the disposable sterilized transfusion device of this utility model, the feed liquor pin is inserted infusion bottle, because feed liquor pin needle body is longer, the gas outlet of make-up gas is near at the bottom of the infusion bottle, replenishing air just can be without medicinal liquid, and medicinal liquid then enters the fluid duct by the inlet on the needle body, through conduit, flow regulator, flow indicator, intravenous needle enter human vein, finish transfusion work.
From the technical solution of the utility model as can be seen, do not pass through medicinal liquid owing to replenish air, reduced in the air antibacterial to the pollution of medicinal liquid, and owing on infusion bottle, do not change, the transfusion medicine bottle can be reused after sterilization, hence one can see that, and the purpose of this utility model can realize.
The specific embodiment:
Below in conjunction with accompanying drawing this utility model is further described:
Fig. 1 is this utility model structural representation.
Embodiment 1: design a feed liquor pin 9, feed liquor pin 9 is with air inlet duct 6 and goes out The needle body in liquid duct 7, an end of needle body is needle point, make-up gas gas outlet 10 is positioned at Needle tip, the other end close end of needle body radially is provided with a boss 13, in the boss 13 Hole 14 communicates with air inlet duct 6, and needle point one side is provided with inlet 8 by boss 13 places, Inlet 8 communicates with fluid duct 7. Air inlet duct 6 needle point one ends far away are embedded with plug 5, The end connecting duct of feed liquor pin 9 can set up one between the end of conduit and feed liquor pin 9 Filter membrane, with filtering liquid medicine, flow control valve 4, flow indicator 2, flow indication Device 2 is provided with dosing mouth 3, and flow indicator 2 other ends are by conduit and intravenous injection Pin 15 links to each other, and intravenous needle 15 overcoats have overcoat 16, use during for ease of blood transfusion, Present embodiment is being set up flow accent on the flow indicator 2 and between the intravenous needle 15 Joint switch 1, additional tracheae is connected to boss 13, and the other end connects air-intaking adjusting valve 11 With air bag 12.
Embodiment 2: design a feed liquor pin 9, feed liquor pin 9 is with air inlet duct 6 and goes out The needle body in liquid duct 7, an end of needle body is needle point, make-up gas gas outlet 10 is positioned at Needle tip, the other end close end of needle body radially is provided with a boss 13, in the boss 13 Hole 14 communicates with air inlet duct 6, and needle point one side is provided with inlet 8 by boss 13 places, Inlet 8 communicates with fluid duct 7. Air inlet duct 6 needle point one ends far away are embedded with plug 5, The end connecting duct of feed liquor pin 9 can set up one between the end of conduit and feed liquor pin 9 Filter membrane, with filtering liquid medicine, flow control valve 4, flow indicator 2 (present embodiments Flow indicator is selected rotary-type flow indicator), flow indicator 2 is provided with dosing Mouth 3, flow indicator 2 other ends link to each other vein by conduit with intravenous needle 15 Entry needle 15 overcoats have overcoat 16, and additional tracheae is connected to boss 13, the other end connect into Controlled atmosphere joint switch 11 and air bag 12.
