Abstract
A closed type drainage instrument for thoracic cavity comprises a drainage bottle with a bottle cap, and the utility model is provided with an exhaust pipe and a water sealing pipe which pass through the bottle cap. The utility model is characterized in that the tail end of the water sealing pipe is provided with a check valve, and is mainly used fro drainage instruments.
Description
Technical field
This utility model relates to medical instruments field, relates in particular to a kind of drainage device.
Background technology
Drainage device of the prior art comprises the drainage bottle of being with bottle cap, passes bottle cap and is provided with exhaustor and water sealing (sealing water) pipe, although this drainage device water seal effect is pretty good, in case drainage bottle tilts, because the water seal mouth of pipe does not have plugging device, very easily causes gas to flow backwards.
Summary of the invention
This utility model has proposed a kind of closed drainage of pleural cavity device at deficiency of the prior art, and it can effectively stop gas to flow backwards.
This programme is realized by following technical measures: it comprises the drainage bottle of being with bottle cap, passes bottle cap and is provided with exhaustor and water sealing (sealing water) pipe, it is characterized in that being provided with check valve at the water sealing (sealing water) pipe end.
The beneficial effect of this programme can learn that owing to adopt check valve, even drainage bottle is toppled over, check valve also can stop gas to flow backwards, so this utility model compared with prior art, realized technical purpose according to the narration to such scheme.
The concrete characteristics of this programme also have, described check valve comprises that top is set in the sleeve pipe on the water sealing (sealing water) pipe, described sleeve pipe bottom is provided with baffle plate with holes, can prevent that ball float from skidding off sleeve pipe, the ball float that can slide along internal surface of sleeve pipe and cooperate realization shutoff gas passage with the sleeve opening of an end is set in sleeve pipe.Be symmetrical arranged at least 3 projecting tendons of joining on the described internal surface of sleeve pipe with the ball float cunning, can to ball float guiding and not the existence of reason ball float influence gas and normally circulate.Described projecting tendon is 4.The drainage catheter front portion in the insertion thoracic cavity that is connected with described water sealing (sealing water) pipe upper end is provided with one section corrugated nozzle, can prevent tube wall depression obstruction pipeline after the drainage catheter bending.The sidewall of described drainage catheter leading section is provided with oval foramen, can prevent that the drainage catheter front port is plugged after, gas still can be derived from the sidewall oval foramen.

The specific embodiment
Shown in Fig. 1～2, it comprises the drainage bottle 6 of being with bottle cap 5, pass bottle cap 5 and be provided with exhaustor 7 and water sealing (sealing water) pipe 3, exhaustor 7 and water sealing (sealing water) pipe 3 all with bottle cap 5 water-stops, be provided with check valve 12 at water sealing (sealing water) pipe 3 ends.Described check valve 12 comprises that top is set in the sleeve pipe 2 on the water sealing (sealing water) pipe 3, sleeve pipe 2 and water sealing (sealing water) pipe 3 water-stops, described sleeve pipe 2 bottoms are provided with baffle plate with holes 4, the ball float 1 that can slide along sleeve pipe 2 inwalls and cooperate realization shutoff gas passage with the sleeve opening of an end is set in sleeve pipe 2, and ball float spheroid proportion is less than 1.As shown in Figure 2, being symmetrical arranged 4 projecting tendons 8 of joining with ball float 1 cunning on described sleeve pipe 2 inwalls, also can be 3 projecting tendons.As shown in Figure 3, drainage catheter 11 front portions in the insertion thoracic cavity that is connected with described water sealing (sealing water) pipe 3 upper ends are provided with one section corrugated nozzle 9.The sidewall of described drainage catheter 11 leading sections is provided with oval foramen 10.
In the use, thoracic cavity gas malleation during normal drain, ball float 1 falls, and liquid passes from the gap between ball float 1 and the sleeve pipe 2, and the orifice flow on baffle plate 4 goes out.Topple over as drainage bottle 6, the moving ball float 1 of air-flow suction is blocked the water seal mouth of pipe and is prevented that gas from flowing backwards when intrathoracic negative pressure.
According to above-mentioned principle, structure is made small change and modification, also be considered as protection domain of the present utility model.
