The utility model is characterized in that the infusion apparatus being able to filter particles and eliminate bubbles is provided with a filter of which the upper section of the filter (5) and the lower section of the filter are combined into a whole. The filter material (13) is arranged between the upper and the lower sections of the filter, the upper section of the filter is provided with an exhaust pipe (7), and the lower section of the filter is provided with a liquid collecting pipe (9). The filter can guarantee that the liquid medicine can flow downwards through the filter material. The filter can guarantee that the bubbles don't enter a human body regardless of being positioned perpendicularly, being positioned horizontally, being positioned in inclination and even inversion.
Description
Can filter particulates be about medical Transfusion device with the transfusion device of removing bubble, particularly can filter particulates and a kind of safe transfusion system of removing bubble.
The present disposable transfusion device that generally uses, owing to be subjected to the restriction in working condition, production technology and transfusion place, the bubble that occurs in the control of insoluble microparticle and the transfusion catheter is failed properly to solve: if any liquid medicine filter, there is the space around its filtering material, can not guarantees the medicinal liquid filtering material of all flowing through; Mobile medicinal liquid is also usually because bubble appears in physical action or anthropic factor in conduit.Because medicinal liquid always requires storage in the cool, and transfusion place such as ward, because there is the people to live within it, temperature always is higher than storage medicine place, this temperature difference is more obvious in winter.We know, the coefficient of tension of all liquid is along with the rising of temperature reduces, practice is proof also, as long as there is the temperature difference in the storage medicine with transfusion two places, place, the medicinal liquid that circulates in elongated transfusion catheter will absorb extraneous heat by very thin catheter wall, just having trickle bubble in the medicinal liquid separates out, the special bubble that is produced when heating to transfusion among arctic weather is just more, the merging of attracting each other of these minute bubbles, produce bigger bubble, become vent plug at last, pushed human body by medicinal liquid.Occur bubble in the blood vessel, when more bubble especially occurring, just the gas embolism phenomenon may take place.Therefore, bubble occurs in the tube for transfusion and insoluble microparticle works the mischief to human body equally,, during clinical transfusion,, just must in time get rid of, in order to avoid future trouble if find in the tube for transfusion bubble is arranged for avoiding taking place gas embolism.
Purpose of the present invention, just provide the transfusion device of a kind of energy filter particulates and removing bubble, make the effect of filter particulates be higher than the liquid medicine filter of present use, and make no matter the bubble that appears in the tube for transfusion owing to what reason can in time be removed, thereby guarantee safe infusion, avoid taking place malpractice.
The scheme that solves this medical skill problem is that the part near human body installs a stripper additional on transfusion device, and its effect is with microgranule in the tube for transfusion and bubble filtering, only allows medicinal liquid enter human body.This stripper is a cylinder or the approximation made with the tube for transfusion same type of material, and its internal diameter facts have proved that greater than the transfusion catheter internal diameter stripper internal diameter is that about three times of transfusion catheter internal diameter are advisable.Stripper is divided into two sections, with the link into an integrated entity back sealing of modes such as grafting, screw thread or bayonet socket, filtering material is housed between the two sections, and compresses with the binder end face of the two sections periphery with filtering material, and material is descending after filtration to make medicinal liquid.
Use this transfusion device, in the medicinal liquid one that is mixed with microgranule and bubble in the transfusion catheter enters the diameter stripper bigger than transfusion catheter, bubble immediately with separating liquid medicine, accumulate in the top of stripper, medicinal liquid is owing to action of gravity, always below gas, and material filters after filtration, stay insoluble microparticle, have only medicinal liquid to export, enter human body through transfusion needle from hypomere.
It is that the pipe that adds a both ends open on stripper stretches into stripper that the present invention further improves, this pipe is called collector tube, stretching at an interior end opening place is the liquid collecting mouth, an end opening place outside is a liquid outlet, liquid outlet links to each other with transfusion needle, and liquid collecting mouth position is about 1/3rd of the stripper axis; On stripper, adorn one one and communicate, the exhaustor that the other end can be locked with block, this pipe double as chemical feed pipe with stripper.
Because the liquid collecting mouth stretches in the stripper, be positioned at about 1/3rd of axis, make stripper have the function of entrap gas, though with stripper just put, inversion, horizontally-arranged, vertical, level or inclination are because the gas in stripper can only float over above the liquid all the time, the not enough volume three of institute's gas collection body in stripper/for the moment, always below liquid level, gas can not enter collector tube to the opening of collector tube, also just can not enter human body.
If find that the air accumulation in the stripper is too much, near volumetrical three/for the moment, can open the exhaustor block, discharge gas.
The present invention also can be improved, and loads onto air filting material in exhaustor.
Accompanying drawing has been described one embodiment of the present of invention: can filter particulates be contained in stripper top with the transfusion device of removing bubble in known manner by feed liquor pin (1) dropping funnel (2) conduit (3) actuator (4) among the figure, stripper epimere (5) stripper hypomere (6) connects in the mode of pegging graft.Filtering material (13) is housed between epimere binder end face (14) and the hypomere binder end face (15) and its periphery is compressed, stripper epimere (5) has exhaustor (7), block (8) is housed on the exhaustor (7), air filting material (16) is housed in the exhaustor (7), stripper hypomere (6) has collector tube (9), collector tube (9) has liquid outlet (10) in stripper outside, have liquid receiving port (11), transfusion needle (12) below the stripper.
Use and filter particulates to infuse according to a conventional method with the transfusion device of removing bubble.Drain gas in transfusion catheter and the stripper during transfusion beginning; can enter the normal infusion state later on; as be mixed with the medicinal liquid of insoluble microparticle or bubble; enter in the stripper from transfusion catheter (3); because the internal diameter of stripper is much larger than the internal diameter of transfusion catheter; bubble immediately with separating liquid medicine; because buoyancy accumulates in the top of stripper; medicinal liquid is because action of gravity; material is descending after filtration; because stripper epimere binder end face (14) compresses with the periphery of hypomere binder end face (15) with filtering material (13); medicinal liquid material (13) after filtration is descending, can't otherly escape, and wherein insoluble microparticle is promptly by filtering; there is not insoluble microgranule; bubble-free medicinal liquid is exported through liquid outlet, enters human body by transfusion needle (12).The length that collector tube (9) stretches into from stripper hypomere (6) is about 1/3rd of stripper length, because this structure, the not enough stripper volumetrical three/for the moment of the accumulative gas of institute in stripper, no matter how stripper is placed, collector tube (9) opening part is all below liquid level, gas can not enter collector tube (9), just can not enter human body yet.Thereby guarantee the safety of transfusion.Near volumetrical three/for the moment,, open block (8) as the cohesion gas collection body of stripper with exhaustor (7) opening part up, because hydraulic action, institute's gas collection body is promptly discharged from exhaustor (7) automatically, and lid is tightly blocked a shot (8) then, and transfusion is proceeded.Because stripper has the function of above-mentioned entrap gas, even gas not exclusively drains in the stripper, also can guarantee not have air admission collector tube (9), guarantee transfusion safety.Exhaustor (7) double as dosing hole.
The present invention can make the comfortable treatment safely of patient owing to can arbitrarily place near the stripper of human body.
Compact conformation of the present invention, has multiple function, easy and simple to handle, make easily, be convenient to mass production, raw material medical macromolecular materials non-toxic polyvinyl chloride of its use etc. and production technology are all identical with existing disposable transfusion device, are suitable for very much producing producer's product renewal of disposable transfusion device.
