Abstract
An infusion apparatus capable of controlling blood backflow time by using micropore channel sustained release comprises a drip chamber (1), wherein a precise medicine liquid filtering membrane (2) is arranged in the drip chamber (1), and a micropore channel (3) is formed in the precise medicine liquid filtering membrane (2). The infusion apparatus capable of controlling the blood backflow time by using the micropore channel sustained release has the advantages that by arranging the micropore channel in the precise medicine liquid filtering membrane (2), the effect that the air pressure in the drip chamber, remaining liquid, the liquid in a drip tube and the blood pressure of the human body are communicated all the time is ensured, air is also prevented from flowing in or out of the drip tube, liquid dripping in the drip chamber is ensured in a certain period of time, the blood of the human body is prevented from backflow in a certain period of time, more time is earned for nurses, and the nurses can replace infusion bottles with ease. The infusion apparatus is simple in structure, safe in use and good in effect through trial of hospitals, and can delay blood return time for at least 15 minutes.
Description
Technical field
This practical technical field of medical instruments that newly relates to, a kind of transfusion device that utilizes the micro channel slow release can control the blood backflow time specifically.
Background technology
Transfusion device and correlation technique have had a lot of reports at present, applied for a patent 3,000 more than, and product miscellaneous is arranged on market, and these transfusion devices have the sealing air-prevention to enter or other functions, but when realizing its advantage, defect the most fatal is also arranged, after injecting fluid drips off, due to the variation of the air pressure in tube for transfusion, can make blood in human body refund and flow in tube for transfusion, produce the defect of blood backflow, this brings certain negative effect to medical treatment." a kind of transfusion device of automatic exhausting anti-blood backflow " that the patent No. is 201010293593.7, though the membrane technology that has utilized the precision liquid medicine filter membrane more first to spout like this, but the precision liquid medicine filter membrane is placed on the bottom of dropping funnel, after medicinal liquid in dropping funnel drips off, wet precision liquid medicine filter membrane can completely cut off the inflow of gas, but the variation due to pressure in medicinal liquid, blood pressure in blood vessel is greater than the pressure in medicinal liquid and refluxes, clinical practice proves, the blood be penetrated in drug liquid tube can't be back in blood vessel again, Er Qie Sui the passing of time and oozes more and more can form thrombosis, cure the disease and be with fork-like farm tool used in ancient China painful greatly to the patient, wasted the medicinal liquid in the drug liquid tube.In addition the fork-like farm tool used in ancient China that is with holes on the precision liquid medicine filter membrane of applying for a patent also had is controlled flow and time, these seem theoretically and hold water, but in fact hole is little of certain size, and moisture film has just been shut hole, causes air pressure obstructed, can't make atmospheric pressure be used to lead to, can't stop blood back, if orifice size is slightly large, atmospheric pressure directly is used to lead to, like this medicinal liquid flow and during injection the mobile of medicinal liquid be the same, be to control the not time of blood back.
Summary of the invention
A kind of micro channel slow release that utilizes of this practical new purpose research makes the residue medicinal liquid in dropping funnel keep being communicated with by the atmospheric pressure in micro channel and bottle, human blood-pressure is delayed under the moving pressure of cross flow in medicinal liquid all the time, delayed like this time, blood can not refluxed within the time of needs.
This practical new transfusion device that utilizes the micro channel slow release can control the blood backflow time, comprise: dropping funnel 1, be provided with precision liquid medicine filter membrane 2 in dropping funnel 1, be provided with on precision liquid medicine filter membrane 2 on micro channel 3 or the dropping funnel body below the precision liquid medicine filter membrane and be provided with micro channel.
Described precision liquid medicine filter membrane is arranged on the position of the required required amount of liquid medicine of control time of dropping funnel;
Described required amount of liquid medicine of required control time=required control not blood back time * medicinal liquid per minute drip number.
The number that drips of medicinal liquid per minute is 1-5.
The position of required required amount of liquid medicine of control time is 1/5 ~ 1/2 place in dropping funnel generally.
Described micro channel comprises: through hole, be provided with filler or the through hole of slow release solution in through hole, and that sticks the not water flowing of ventilating on through hole crosses filter Mo.
The precision liquid medicine filter membrane is bonded on dropping funnel by hot pressing or other method.
The diameter of described through hole is depending on required control time of blood back not, by the method for experiment, obtain, the method of described experiment is with designing the micro channel of different diameters on the precision liquid medicine filter membrane in the dropping funnel of scale, on the precision liquid medicine filter membrane injecting liquid drug complete after, remaining liquid medicine under the precision liquid medicine filter membrane minute every clock from pin drips how many, how long the micro channel of the surplus liquid different-diameter of equal height each drip off, so just can obtain set of number, Ke Yi Suan goes out how many medicinal liquids per minute of each diameter, design is during the control time like this, as long as where the precision liquid medicine filter membrane is placed on to dropping funnel, in dropping funnel, remaining how many surplus liquid has just been determined, how many medicinal liquids per minute of each diameter drawn in experiment, how long so just can roughly draw can blood back.
But the material that the filler of described slow release solution is cotton thread or other singles or other absorbent solution and slow release solution, its diameter is at 0.1～3mm.
This practical new transfusion device that utilizes the micro channel slow release can control the blood backflow time is so real Now: after the injecting fluid injection soon of precision liquid medicine filter membrane top, the residue medicinal liquid keeps being communicated with by the atmospheric pressure in micro channel and bottle, human blood-pressure is delayed under the moving pressure of cross flow in medicinal liquid all the time, delayed like this time, blood can not refluxed within the time of needs.
This practical new advantage of utilizing the micro channel slow release can control the transfusion device of blood backflow time is: by the precision liquid medicine filter membrane, being provided with micro channel, not only guaranteed air pressure in the dropping funnel. liquid in remaining liquid and dropper. the connection all the time of human blood-pressure, and the inflow that has prevented air goes out dropper, guaranteed that within the regular hour liquid that has in the dropping funnel oozes, prevented that the blood of human body does not reflux within a certain period of time, for the nurse strives for the more time, the nurse can change infusion bottle freely, this apparatus structure is simple, use safety, good by hospital's trial effect, can delay Blood return time minimum 15 minutes.
