Abstract
The utility model relates to an infusion apparatus without blood backflow, belonging to the technical field of medical infusion apparatus. The infusion apparatus mainly comprises a liquid medicine bottle (1), a liquid inlet needle (2), an air inlet tube (3), a drop pot (4), an infusion tube (5), an adjuster (6), a controller (8) without blood backflow, a filter (9) and a liquid outlet needle (7), and is characterized in that: by arranging the controller (8) without blood backflow in an infusion pipeline, the infusion apparatus without blood backflow prevents the occurrence of blood backflow in the infusion process effectively, relieves the pain of patients greatly, reduces the occurrence of medical accidents, has reasonable design, simple structure, flexible using method, safety, reliability and low cost, and is an ideal infusion apparatus.
Description
Technical field
This utility model belongs to the medical Transfusion device technical field, relates to a kind of disposable transfusion device, especially a kind of transfusion device that can prevent blood back automatically.
Background technology
Present known medical Transfusion device is that infusion bottle is uphang on support, air inlet needle connects air inlet pipe, the fluid pin, tube for transfusion, drip kettle, transfusion needle forms, air is from air inlet pipe, air inlet needle enters infusion bottle, keep pressure of the inside of a bottle and external atmosphere pressure balance, infusion bottle is uphang on support, press to guarantee certain high position, medicinal liquid is continued to flow into human body, but be totally lost or during the infusion bottle insufficient height, when the tube for transfusion internal pressure is lower than human blood-pressure when medicinal liquid, will cause blood back, if blood solidifies, just need change transfusion device, once more acupuncture treatment in syringe needle and tube for transfusion, this brings very big inconvenience for clinical use, the life security that also can threaten patient when serious.Disclose a kind of Transfusion system without blood return (99203580.5) at present, this device only at the situation that blood back takes place, is not lower than the blood back problem that human blood-pressure produces but solve other owing to tube for transfusion is intrinsic pressure when medicinal liquid drips off.
Summary of the invention
The purpose of this utility model provides a kind of disposable Transfusion system without blood return that can prevent that blood from refluxing.
Realize that scheme of the present utility model is as follows:
A kind of Transfusion system without blood return, form by medicinal liquid bottle (1), feed liquor syringe needle (2), air inlet pipe (3), a kettle (4), actuator (6), filter (9) and liquid discharging pinhead (7), above-mentioned each device is linked in sequence by tube for transfusion, is dripping kettle to being provided with not blood back controller (8) between the liquid discharging pinhead.The blood back controller is not made up of inlet (10), overhead gage (11), ball (12), lower baffle plate (13), liquid outlet (14) and shell (15), wherein overhead gage and lower baffle plate are located between inlet and the liquid outlet in the shell cavity, and ball is located between overhead gage and the lower baffle plate.The density of ball is 0.9～2.0g/cm
3
This utility model provides a kind of disposable Transfusion system without blood return that can prevent that blood from refluxing, effectively prevented the generation of blood back, not blood back transfusion controller in this utility model is detachable simultaneously, can with the supporting use of present transfusion device, also can directly implant whole use the in the traditional infusion device, simple in structure, using method is flexible, and is cheap.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified
Fig. 1 is a Transfusion system without blood return overall work sketch map.
Fig. 2 is a blood back controller architecture sketch map not.
Fig. 3 is a blood back controller profile not.
Fig. 4 is blood back controller bottom section figure not.
The specific embodiment
This utility model is characterized in that when using this utility model, medicinal liquid flows into through inlet, and the hydraulic pressure of inlet is greater than liquid outlet, and at this moment, ball is close to lower baffle plate, and medicinal liquid freely flows out through the baffle plate space, can finish normal infusion.
When the hydraulic pressure of inlet during less than liquid outlet, this moment, ball was close to the overhead gage place, injection port is stopped up, thereby keep certain hydraulic pressure in the tube for transfusion, made the unlikely refluence of blood, had prevented the generation of blood back.
Embodiment 1
The blood back controller is not placed between actuator and the filter; Its overall structure is made up of shell (15), funnel-form overhead gage (11), ball (12), wedge shape lower baffle plate (13), inlet (10), liquid outlet (14); Ball density is 0.95g/cm
3, overhead gage is designed to funnel-form, and its maximum inner diameter is greater than the straight warp of ball, and minimum diameter is less than the diameter of ball, and lower baffle plate is designed to be evenly distributed 4 wedge shape catch, hollow, the hollow space diameter is less than the ball diameter; Inlet and liquid outlet are provided with the interface of energy and actuator tube for transfusion filter tube for transfusion and coupling, with for convenience detach.
Embodiment 2
A kind of Transfusion system without blood return, form by medicinal liquid bottle (1), feed liquor syringe needle (2), air inlet pipe (3), a kettle (4), actuator (6), filter (9) and liquid discharging pinhead (7), above-mentioned each device is linked in sequence by tube for transfusion (5), it is characterized in that: dripping kettle (4) to being provided with not blood back controller (8) between the liquid discharging pinhead (7).Blood back controller (8) is not made up of inlet (10), overhead gage (11), ball (12), lower baffle plate (13), liquid outlet (14) and shell (15), wherein overhead gage (11) and lower baffle plate (13) are located between inlet (10) and the liquid outlet (14) in the shell cavity, and ball (12) is located between overhead gage (11) and the lower baffle plate (13).The density of ball (12) is 0.9～2.0g/cm
