Description
Technical field
This utility model product belongs to technical field of medical equipment, is specifically related to the anti-drainage bag that backflows of a kind of single use.
Technical background
The patient of splanchnocoel drain or indwelling catheter often needs to use drainage bag, patient stand up or out-of-bed activity time, the liquid that often there will be in bag cavity volume can return in patient body through drainage tube, causes and infects and even even more serious consequence.Another still unimpeded between drainage bag and drainage tube during non-drain, add extraneous antibacterial and entered chance in patient body by drainage system.Existing drainage bag arranges flow-stop valve usually on union joint, but due to guide wire pipeline tiny, and flow-stop valve structure is more complicated, causes flow-stop valve structural stability not good enough, easily loses efficacy, and loses counterflow-preventing effect.
Summary of the invention
The purpose of this utility model, is to provide a kind of structure simple, anti-backflow good stability, the easy to operate anti-drainage bag that backflows.
This utility model is realized by following technical scheme, the anti-drainage bag that backflows of single use, comprises and introduces joint 01), introduce joint block (02), introduce conduit (03), pipe clamp (04), liquid storing bag (05), bedsheet clamp (06), accurate liquid containing bottle (07), the anti-valve (08) that backflows, Connection Block (09), hook (10), cross valve (11), holder (12); Screwed union (13), screwed union cap (14), discharge pipe (15) and lanyard (16), it is characterized in that the anti-valve that backflows adopts from on-off structure form, comprise valve body and spool, valve body is the spherical shell structure of two ends carrying pipe, spool top is spherical shell, bottom is the conduit of band side opening, and spool can move up and down along duct direction in valve body.
When flowing into without drainage-fluid, the anti-valve core that backflows is positioned at body base, and spool conduit with holes all inserts valve body lower portion conduit, plays the accurate liquid containing bottle effect (Fig. 2) of sealing.When there being drainage-fluid to prevent backflowing valve from the inflow of introducing conduit, spool rises by drainage-fluid buoyancy, and be positioned at the supravasal hole of spool also rises thereupon, and drainage-fluid flows into accurate liquid containing bottle (Fig. 3) by the hole of exposing.After drainage-fluid all flows into accurate liquid containing bottle, the buoyancy suffered by spool disappears, and the anti-valve that backflows is in closed condition (Fig. 2).When there being drainage-fluid to backflow from accurate liquid containing bottle, first drainage-fluid is flowed in the spherical shell of spool by the conduit of spool, and spool rises along with the inflow of drainage-fluid, the inlet of sealed valve body, and drainage-fluid cannot be backflowed to introducing conduit (Fig. 4).
This utility model have employed above-mentioned technical solution, effectively can prevent the drainage-fluid collected from backflowing, prevent from causing retrograde infection and the mishandling pathophoresis that may occur of drainage-fluid because drainage-fluid backflows.This utility model product structure is novel, and production technology is simple, and product is slim and graceful, and economical and practical, medical personnel are simple to operate, easy to use, do not affect normal drainage procedure flow process, is convenient to clinical expansion and uses.
Below in conjunction with drawings and Examples, this utility model product is further described.

Specific embodiment
As shown in Figure 1, the anti-drainage bag that backflows of single use comprises: 01-introduces joint; 02-introduces joint block; 03-introduces conduit; 04-pipe clamp; 05-liquid storing bag; 06-bedsheet clamp; The accurate liquid containing bottle of 07-; The anti-valve that backflows of 08-; 09-Connection Block; 10-links up with; 11-cross valve; 12-holder; 13-screwed union, 14-screwed union cap, 15-discharge pipe, 16-lanyard.
The anti-drainage bag that backflows of single use, comprises and introduces joint 01), introduce joint block (02), introduce conduit (03), pipe clamp (04), liquid storing bag (05), bedsheet clamp (06), accurate liquid containing bottle (07), the anti-valve (08) that backflows, Connection Block (09), hook (10), cross valve (11), holder (12); Screwed union (13), screwed union cap (14), discharge pipe (15) and lanyard (16), it is characterized in that the anti-valve that backflows adopts from on-off structure form, comprise valve body and spool, valve body is the spherical shell structure of two ends carrying pipe, spool top is spherical shell, bottom is the conduit of band side opening, and spool can move up and down along duct direction in valve body.
Fig. 2 is the anti-valve schematic diagram when flowing into without drainage-fluid that backflows.The anti-valve that backflows comprises valve body (81) and spool (82), the spherical shell structure that valve body (81) is two ends carrying pipe, upper catheter (811) is connected with introducing conduit (03), bottom conduit (812) is connected with accurate liquid containing bottle (07). and spool (82) top is spherical shell structure (821), bottom is the conduit (822) with side opening (823), conduit (822) inserts in valve body lower portion conduit (812), and spool (82) can move up and down in valve body (81).When flowing into without drainage-fluid, the anti-valve core (82) that backflows is positioned at valve body (81) bottom, and spool conduit (822) all inserts valve body lower portion conduit (812), plays the accurate liquid containing bottle of sealing (07) effect.
Fig. 3 is the anti-valve schematic diagram when there being drainage-fluid to flow into that backflows of this anti-drainage bag that backflows.When there being drainage-fluid to prevent backflowing valve (08) from introducing conduit (03) inflow, spool (82) rises by drainage-fluid buoyancy, be positioned at the supravasal side opening of spool (823) also to rise, drainage-fluid flows into accurate liquid containing bottle (07) by the side opening (823) exposed thereupon.After drainage-fluid all flows into accurate liquid containing bottle (07), the buoyancy suffered by spool (82) disappears, and the anti-valve (08) that backflows is in closed condition.
Fig. 4 is the anti-valve schematic diagram when there being drainage-fluid to backflow that backflows of this anti-drainage bag that backflows.When there being drainage-fluid to backflow from accurate liquid containing bottle (07), first drainage-fluid flows in spool spherical shell (821) by spool conduit (822), spool (82) rises along with the inflow of drainage-fluid, spool spherical shell (821) contact with valve body upper catheter (811) and sealing duct on inlet opening, make drainage-fluid cannot backflow to introducing conduit (03).
