Abstract
The utility model discloses a kind of abacterial transfusion system; comprise the perforator, dropping funnel, conduit and the venoclysis needle that connect successively; air inlet device is provided with below described perforator; conduit is provided with flow regulator; described air inlet device is provided with air inlet pipe protruding outward; air inlet pipe is provided with back flow protection device, and this utility model has the effect of automatic liquid-stopping, current stabilization, adds the safety of patient in infusion process and comfortableness.
Description
Technical field
This utility model relates to medical abacterial transfusion system.
Background technology
At present, clinically carrying out patient needing in infusion process to monitor the liquid level in transfusion device, if after having infused not in time process can cause blood back situation, serious words also can cause air to enter human body, jeopardize the life security of patient.
Utility model content
This utility model object is to overcome above-mentioned the deficiencies in the prior art, provides a kind of abacterial transfusion system with back flow protection device, automatically closes air inlet, realize automatic liquid-stopping after transfusion completes under gas pressure.
The technical solution of the utility model is: a kind of abacterial transfusion system, comprise the perforator connected successively, dropping funnel, conduit and venoclysis needle, air inlet device is provided with below described perforator, conduit is provided with flow regulator, described air inlet device is provided with air inlet pipe protruding outward, air inlet pipe is provided with back flow protection device, described back flow protection device comprises the housing of pedestal and tubular, described pedestal is provided with connector, one end and the pedestal of housing connect as one, the other end of housing is provided with back flow protection device air inlet, the both sides of back flow protection device air inlet are respectively provided with a column paralleled with housing sidewall, two root posts slidably connect catch, two described root posts are all also equipped with spring, one end of spring is fixedly connected on housing and is provided with on the end face of back flow protection device air inlet, the other end of spring is connected with catch, also spacing ring is provided with outside described air inlet pipe, air inlet pipe to be inserted in housing through connector and limited ring institute is spacing, gap is remained with between described air inlet pipe and catch.
The diameter of described back flow protection device air inlet is less than the diameter of air inlet pipe.
Two described root posts and the junction of housing are also provided with spring bayonet socket, and one end of described spring is fixed on spring bayonet socket.
Described connector is also provided with rubber seal.
Described catch is also provided with pull bar, and pull bar to extend housing from back flow protection device air inlet and is provided with draw ring in end.
The beneficial effects of the utility model are: when air pressure change in catheter tube, namely do not have in body liquid or flow rate of liquid too fast time, catch can block air inlet under the influence of air pressure, thus reach the effect of automatic liquid-stopping, when refilling liquid or flow restoration in body to time normal, catch can reset under the action of the spring, achieves anti-return blood, and stablize the effect of flow velocity, make patient safer in infusion process, comfortable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of this utility model back flow protection device.
In figure: perforator 1, dropping funnel 2, conduit 3, venoclysis needle 4, air inlet device 5, flow regulator 6, air inlet pipe 7, pedestal 8, housing 9, connector 10, back flow protection device air inlet 11, column 12, catch 13, spring 14, spacing ring 15, spring bayonet socket 16, rubber seal 17, pull bar 18, draw ring 19, back flow protection device 20.
Detailed description of the invention
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Shown in composition graphs 1 and Fig. 2, a kind of abacterial transfusion system, comprise the perforator 1 connected successively, dropping funnel 2, conduit 3 and venoclysis needle 4, air inlet device 5 is provided with below described perforator 1, conduit 3 is provided with flow regulator 6, described air inlet device 5 is provided with air inlet pipe 7 protruding outward, air inlet pipe 7 is provided with back flow protection device 20, described back flow protection device 20 comprises the housing 9 of pedestal 8 and tubular, described pedestal 8 is provided with connector 10, one end and the pedestal 8 of housing 9 connect as one, the other end of housing 9 is provided with back flow protection device air inlet 11, the both sides of back flow protection device air inlet 11 are respectively provided with a column 12 paralleled with housing 9 sidewall, two root posts 12 slidably connect catch 13, two described root posts 12 are all also equipped with spring 14, one end of spring 14 is fixedly connected on housing 9 and is provided with on the end face of back flow protection device air inlet 11, the other end of spring 14 is connected with catch 14, spacing ring 15 is also provided with outside described air inlet pipe 7, air inlet pipe 15 to be inserted in housing 9 through connector 10 and limited ring 15 institute is spacing, gap is remained with between described air inlet pipe 15 and catch 13, the diameter of described back flow protection device air inlet 11 is less than 15 diameters of air inlet pipe, two described root posts 12 are also provided with spring bayonet socket 16 with the junction of housing 9, one end of described spring 14 is fixed on spring bayonet socket 16, described connector 10 is also provided with rubber seal 17, described catch 13 is also provided with pull bar 18, pull bar 18 to extend housing 9 from back flow protection device air inlet 11 and is provided with draw ring 19 in end.
When air pressure change in catheter tube, namely do not have in body liquid or flow rate of liquid too fast time, catch can block air inlet under the influence of air pressure, thus reach automatic liquid-stopping, the effect of anti-return blood, when refilling liquid or flow restoration in body to time normal, when namely catheter tube internal gas pressure is normal, catch can reset under the action of the spring, and such structure makes transfusion device achieve the effect of stable medicinal liquid transporting velocity to a certain extent simultaneously.
