Abstract
An infusion apparatus capable of preventing blood from backflow by using micropore channel sustained release comprises a drip chamber (1), and a floating body (2) is arranged in the drip chamber (1). The infusion apparatus capable of preventing the blood from backflow by using the micropore channel sustained release is characterized in that a micropore channel (3) is form in the lower portion of the drip chamber (1), wherein the micropore channel (3) is communicated with a drip tube (9) connected with the drip chamber. The infusion apparatus capable of preventing the blood from backflow by using the micropore channel sustained release has the advantages that by means of a fiber stick which serves as media, the effect that the air pressure in the drip chamber, remaining liquid, the liquid in the 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 utility model relates to technical field of medical instruments, specifically a kind of transfusion device that utilizes micro channel slow release blood-backflow preventing.
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.
Summary of the invention
A kind of transfusion device that utilizes micro channel slow release blood-backflow preventing of the purpose of this utility model research, specifically after injecting fluid injection soon, by the seal that a buoyancy aid bottom in dropping funnel is installed, the outlet of dropping funnel bottom is sealed, then the remaining liq in dropping funnel slowly flows in dropper by the rod of the fiber in micro channel slow release, make human blood-pressure all the time under the pressure in liquid flow, blood can not reflux.
This utility model utilizes the transfusion device of micro channel slow release blood-backflow preventing, comprising: dropping funnel 1, be provided with buoyancy aid 2 in dropping funnel 1, and be provided with micro channel 3 or 10 on the dropping funnel body or on buoyancy aid.
Described micro channel 3 or 10 comprises: through hole 7 is provided with microporous fibre rod 8 in through hole 7.
The micro channel 3 arranged on described dropping funnel body is the passages that are connected with between the connected dropper 9 of the bottom of dropping funnel 1 and dropping funnel 1.
The micro channel 10 arranged on described buoyancy aid 2 is passages that arrange on the soft bag of seal 5.
Described buoyancy aid 2 comprises: ball float 4 and seal 5, ball float 4 is connected by being connected pole 6 with seal 5.
Described connection pole 6 is the solid body of rod or cylindrical drum; If cylindrical drum, the two sides of cylindrical drum respectively have the hole of a plurality of upper and lower different distance.
How long not the height of described connection pole 6 is depending on how much liquid of Xu Sheng Liu in dropping funnel 1, that is to say depending on control blood back.
Described not Blood return time is that in dropping funnel 1, per minute the dripping of Xu Sheng Liu amount of liquid ÷ counted.
The per minute number that drips is 1-5.
Described seal 5 is conical soft bag, conical soft bag, spherical soft bag, cylindrical soft bag or the soft bag of stairstepping.
Described micro channel 3 comprises: through hole 7 is provided with microporous fibre rod 8 in through hole 7.
The diameter of described through hole 7 is 0.1-3mm.
Described microporous fibre rod 8 be that the described microporous fibre rod 8 of cotton thread or other singles is cotton thread or other singles, but or the material of other absorbent solution and slow release solution, its diameter is at 0.1～3mm.
This utility model profit utilizes the transfusion principle of micro channel slow release blood-backflow preventing to be:
After injecting fluid injection soon, by the seal that a buoyancy aid bottom in dropping funnel is installed, the outlet of dropping funnel bottom is sealed, then the remaining liq in dropping funnel slowly flows in dropper by the rod of the fiber in micro channel slow release, make human blood-pressure all the time under the pressure in liquid flow, blood can not reflux.
Adding microporous fibre rod in micro channel has certain moisture and release outlet capacity, after liquid in minim pipette soon drips to the greatest extent, the outlet of dropping funnel bottom is sealed, then the air pressure that the remaining liq in dropping funnel can maintain by a small amount of water in the microporous fibre rod in tube for transfusion communicates with the blood pressure in blood, and has prevented the inflow drain pipe of air.
This utility model profit utilizes the advantage of the transfusion device of micro channel slow release blood-backflow preventing to be: by the fiber rod as medium, 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 prevented that the inflow of air from going 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, and this apparatus structure is simple, uses safety, good by hospital's trial effect, can delay Blood return time minimum 15 minutes.
