Abstract
The utility model relates to a safety liquid infusing device, which is composed of a liquid inlet needle (1), an upper guide tube (2), a dripping bucket (3), a liquid infusing guide tube (4) and a needle holder (11). The utility model is characterized in that the utility model is provided with a safety tube (7) and a liquid collecting tube (9) which is provided with a liquid collecting opening (8), and the safety tube (7) is extended into the liquid collecting opening (8). The safety tube can ensure air bubbles not to enter human body regardless of how the safety tube is placed.
Description
Safe transfusion system is about medical Transfusion device, particularly a kind of utility model medical apparatus and instruments of medical safe transfusion device.
In the transfusion clinical practice, usually find owing to aerofluxus not to the utmost careless manipulation make the air admission transfusion catheter, mobile medicinal liquid in conduit, also usually because with the variations in temperature in former when storage and because transfusion device each several part diameter is different, flow velocity does not wait caused pressure change and separates out the gas that is dissolved in originally in the medicinal liquid, it is obvious especially when the latter heats to transfusion in cold snap, the gas that these are separated out from medicinal liquid, very small during beginning, their merging of attracting each other, produce bigger bubble, become the vent plug in the tube for transfusion at last, pushed human body by medicinal liquid, though blood of human body can dissolve a small amount of gas, but well-known, bubble enters the people to be known from experience and brings adverse effect, and bigger bubble enters the consequence of human body and is difficult to predict.
A kind of known transfusion device is arranged, when the transfusion beginning, can discharge the air in the tube for transfusion, but it is in infusion process, the bubble that in conduit, produces owing to physical cause, and because artificial, as the bubble that produces behind the air admission conduit in the dropping funnel when rocking transfusion device is helpless.
Purpose of the present invention just provides a kind of safe transfusion system, makes no matter the bubble that appears in the tube for transfusion owing to what reason all can not enter human body, thereby guarantees safe infusion, avoids having an accident.
The scheme that solves this medical skill problem is: the part near human body on transfusion device installs a bursting tube additional, its effect is bubble and the separating liquid medicine that will occur in the tube for transfusion, do not allow the gas intravasation, this bursting tube is one and uses cylinder or the approximation made from the same material of tube for transfusion, diameter is about three times of transfusion catheter diameter, its upper end links to each other with transfusion catheter, its lower end has a conduit to stretch into to be collector tube, stretches into part and can be about 1/3rd of bursting tube length.
Use this transfusion device, in the medicinal liquid that is mixed with bubble one in the transfusion catheter enters the diameter bursting tube more much bigger than transfusion catheter, bubble immediately with separating liquid medicine, accumulate in the top of bursting tube.Medicinal liquid is because action of gravity, always below gas, and by the collector tube output of bursting tube bottom.Being also advantageous in that of this transfusion device: because the above-mentioned special construction of bursting tube collector tube, make no matter the safety pipe is vertically just to put, still tilting, horizontally-arranged, and even be inverted, because gas can only float over above the liquid the not enough bursting tube volumetrical three/for the moment of institute's gas collection body in bursting tube all the time, because the opening of collector tube always below liquid level, does not enter human body so do not have bubble.
It is to adorn one one to communicate with bursting tube on bursting tube that the present invention further improves, the exhaustor that the other end can be locked with block, and this manages double as chemical feed pipe.
If find that the air accumulation in the bursting tube is too much,, can open the exhaustor block and discharge gas near volumetrical three/for the moment.
Accompanying drawing has been described one embodiment of the present of invention: safe transfusion system is contained in the top of transfusion catheter (4) in known manner among the figure by feed liquor pin (1) upper conduit (2) dropping funnel (3), transfusion catheter (4) lower end communicates with bursting tube (7), the collector tube (9) of bursting tube (7) lower end connects needle stand (11) transfusion needle (12), the connector of bursting tube (7) upper end and transfusion catheter (4) on one side, exhaustor (6) is housed, block (5) is housed on the exhaustor (6).Collector tube (9) outside is furnished with actuator (10), and collector tube (9) stretches in the bursting tube (7), has liquid collecting mouth (8).
Safe transfusion system is infused according to a conventional method.If because above-mentioned artificial origin, the bubble that physical cause occurs is along with after medicinal liquid enters bursting tube (7) from the lower end of tube for transfusion (4), bubble immediately with separating liquid medicine, accumulate in the top of bursting tube (7), medicinal liquid enters human body by collector tube (9) output through needle stand (11) transfusion needle (12).The length that collector tube (9) stretches into from bursting tube (7) lower end central authorities is about 1/3rd of bursting tube (7) length, because this structure, institute's not enough bursting tube of accumulative gas (7) volumetrical three/for the moment in bursting tube (7), no matter how bursting tube is placed, liquid collecting mouth (8) is all below liquid level, gas can not enter collector tube (9) from liquid collecting mouth (8), just can not enter human body yet, thereby has fundamentally guaranteed the safety of transfusion.If accumulative gas is near bursting tube (7) volumetrical three/for the moment in the bursting tube (7), close collector tube (9) with actuator (10), open block (5), push bursting tube (7) with hands, gas is discharged by exhaustor (6), the tight block of lid (5) is opened actuator (10) and is continued transfusion then.Because bursting tube (7) has above-mentioned functions, even the gas in the bursting tube (7) not exclusively drains, can guarantee does not have the air admission blood vessel yet, guarantees transfusion safety.Exhaustor (6) double as dosing hole.
Liquid collecting mouth (8) is made angle; Flat mouthful; Or less than the bore of transfusion catheter (4), can eliminate under the inversion situation, from transfusion catheter (4) medicinal liquid of the bubble of emersion in bursting tube (7) accidental escape into may, mention safety coefficient the highest.
The present invention can make the patient cosily treat owing to can arbitrarily place near the bursting tube (7) of human body.
Structure of the present invention is uncomplicated, and is easy and simple to handle, makes easily, is convenient to mass production, the medical material manufacturings such as available medical macromolecular materials non-toxic polyvinyl chloride. In fact, the present invention only increases by one than Dispoable medical transfusion device and uses same material, the bursting tube assembly that the same process method is made, the producer's product renewal that is suitable for very much producing disposable transfusion device.
