Abstract
The utility model relates to a drainage tube blood-return-resistant infusion set. The infusion set is composed of a dropper, a dripping bucket, a liquid medicine filter and a lower catheter. An exhaust tube is arranged in a closed tube at the top end of an upper cover connecting tube of the liquid medicine filter, and the connecting tube is provided with only one infusion notch and has an automatically exhausting function. The upper cover connecting tube is provided with a drainage channel communicated with a drainage hole to drain residual liquid upward to maintain a trace amount of infusion liquid so as to achieve long-time blood-return-resistance function. A filtering membrane of the liquid medicine filter is a liquid stop filtering membrane with the thickness equal to or larger than 0.5mm and can automatically stop liquid.
Description
Technical field
This utility model relates to a kind of transfusion device, particularly a kind of drainage tube blood return preventing infusion device.
Background technology
Aerofluxus difficulty when existing disposable infusion set uses, medicinal liquid flow the untimely bubble of processing enter to continue to infuse behind the downcomer just pretty troublesome.Particularly medicinal liquid has flowed back blood backflow formation thrombosis, and patient is produced harm.
For addressing these problems, existing automatic vent and the only product of liquid appearance in recent years automatically, but the problem of blood return prevention still fails effectively to solve, though there is a kind of adverse current blood return preventing infusion device that certain effect is arranged, but wear a single imbibition drain, the not only complex process of threading, and single becomes foreign body in dropping funnel, people can't accept.
Summary of the invention
The purpose of this utility model is to provide a kind of drainage tube blood return preventing infusion device, and effectively blood return prevention, and technology is simple, has automatic vent simultaneously, ends the function of liquid automatically.
For solving the above problems, this utility model is to solve by following technical scheme.
This utility model comprises: dropper, dropping funnel, liquid medicine filter and downcomer.The loam cake connecting tube of described liquid medicine filter is inserted in the dropping funnel, its top closure, and there is a transfusion notch on pipe side side, and a steam vent and a conduction hole are arranged at the top of pipe, and the below of conduction hole connects a drain ditch.An aerofluxus drainage tube is arranged, its conduction hole that is equal to or higher than suitable for reading in the loam cake connecting tube.The connecting tube of liquid medicine filter base extends in the base, and its top seal side is other to have a slotted hole to communicate with liquid medicine filter, the bottom of connecting tube and downcomer UNICOM.Used filter membrane is the only liquid filter membrane that a kind of gross thickness is equal to or greater than 0.5mm in the liquid medicine filter.
Compared with prior art, the beneficial effects of the utility model are: simple in structure, only need in the loam cake connecting tube, to add an aerofluxus drainage tube and just can reach blood return prevention and self-bleeding function, the interior used only liquid filter membrane that is of liquid medicine filter, so this utility model has automatic vent simultaneously, ends multiple functions such as liquid, blood return prevention automatically, structure and technology are simple, cost is low.
Description of drawings
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the profile according to the drainage tube blood return preventing infusion device that the utility model proposes.Fig. 2 shows the profile that an exhaustor is arranged in the loam cake connecting tube.
The specific embodiment
Below in conjunction with Fig. 1 and Fig. 2 according to details and the working condition that the utility model proposes.
Fig. 1 is the drainage tube blood return preventing infusion device, it is made up of dropper (13), dropping funnel (2), liquid medicine filter (1), downcomer (11), the loam cake connecting tube (3) of liquid medicine filter has a transfusion notch (4), a steam vent (12) and a conduction hole (5), be a drain ditch (6) below the conduction hole, in the visible loam cake connecting tube of Fig. 2 an aerofluxus drainage tube (7) arranged.Bar air exhausting transfusion slotted hole (9) is arranged at the top of the base connecting tube (8) of liquid medicine filter, and bottom and downcomer (11) are connected.
Be example to scheme, medicinal liquid through dropper (13) enter dropping funnel (2) and with dropping funnel in unnecessary gas discharge automatically through steam vent (12) and aerofluxus drainage tube (7).Because the surface tension effects of liquid, medicinal liquid in the dropping funnel will reach a certain amount of, medicinal liquid just flowed in the liquid medicine filter (1) from the transfusion notch (4) of loam cake connecting tube (3) after gravity surpassed surface tension, and the air exhausting transfusion slotted hole (9) from base connecting tube (8) flows into downcomer (11) after ending liquid filter membrane (10) filtration again.During small amount of residual liquid in medicinal liquid has flowed remaining dropping funnel (2) only, because the surface tension effects of liquid, debris upwards flows into liquid medicine filter (1) along drain ditch (6) in conduction hole (5) enters loam cake connecting tube (3) and from the space between connecting tube and the aerofluxus drainage tube (7).Drain ditch (6) upwards drain will overcome the action of gravity of liquid itself, thus very slow, reaching the effect of trace transfusion, lasting blood return prevention, liquid filter membrane liquid is only automatically ended in the intact back of residual liquid stream.
The connecting tube of this utility model loam cake has only a transfusion notch (4), because the chance that area weak breath bubble enters is also more few, and only liquid filter membrane (10) can stop bubble to enter liquid medicine filter by effectively preventing the gas in the dropping funnel (2) again.The air exhausting transfusion slotted hole (9) of base connecting tube prevents that the bubble in the liquid medicine filter from entering downcomer (11) and reaching the bubble-free effect of automatic vent, ends liquid filter membrane (10) and ends liquid automatically, and the drain ditch is kept the trace transfusion and reached lasting blood return prevention.
Claims (5)
1. a drainage tube blood return preventing infusion device comprises: dropper (13), dropping funnel (2), liquid medicine filter (1); It is characterized in that: the loam cake connecting tube (3) of described liquid medicine filter (1) is inserted in the dropping funnel (2), its top closure, and pipe side side has only a transfusion notch (4), and a steam vent (12) and a conduction hole (5) are arranged at the top of pipe.
2. drainage tube blood return preventing infusion device according to claim 1 is characterized in that: an aerofluxus drainage tube (7) is arranged, its conduction hole (5) that is equal to or higher than suitable for reading in the described loam cake connecting tube (3).
3. drainage tube blood return preventing infusion device according to claim 1 is characterized in that: the filter membrane (10) of described liquid medicine filter (1) be gross thickness be equal to or greater than 0.5mm end the liquid filter membrane.
4. drainage tube blood return preventing infusion device according to claim 1, it is characterized in that: the rarest air exhausting transfusion slotted hole in top (9) of the base connecting tube (8) of described liquid medicine filter (1), the bottom connects with downcomer (11).
5. drainage tube blood return preventing infusion device according to claim 1, it is characterized in that: the below of described conduction hole (5) has a drain ditch (6) to communicate with conduction hole (5).
