Description
Technical field
The invention belongs to technical field of medical equipment, and in particular to medical two-way drainage set, control method and monitoring are pre-
Alert system.
Background technology
When being handled at present for human intracavity, it is often necessary to use flushing and medicine-feeding, particularly as be using catheter/
The apparatuses such as ductus nasopharyngeus are passed through human body, then solution is circulated into affected part, then use siphon principle and come out the liquid drain poured into
Method.Due to rinsing and adding medicine to frequently, indwelling tube is usually being placed in patient body, affected part is being rinsed, removing wherein
Blood clot, mucus, the foreign matter such as bacterium, prevention infection；Surplus fluid is drained, affected part is kept clear.
But current bladder irrigation is mostly the apparatus with big syringe or flusher etc directly through indwelling tube, catheter
Or the injection such as ductus nasopharyngeus；Exported again by indwelling tube, catheter or ductus nasopharyngeus.Many problems in Clinical practice be present in this：
1. the bad control of thrust：Thrust is too small, can extend the time of injection because internal internal pressure injection is not entered；Thrust is too
Greatly, first dose deficiency, waste liquor contamination, reagent corrosion are caused, second increases medical care people easily because of joint loosely leakage everywhere
The working strength of member.
2. under conventional method, being required for having special messenger's nurse when in use, such as require that medical personnel are whole and be responsible for, then waste very much
Hospital resources are in injection, supervision；Such as it is responsible for by family numbers of patients or nurse, then can not plays monitoring because it is lacked experience again
Left and right.In particular by the instrument of flusher etc, family numbers of patients, nurse will not often use again.
3. under conventional method, after completing injection, multi-purpose plug clogs the end of indwelling tube, prevents from infecting.It is but actual
In use, because indwelling tube can leave raffinate in use, cause the resistance deficiency between plug and indwelling tube, along with human body
Inside inherently there is certain pressure, cause plug using being particularly easy to come off after twice, and then make internal liquid suitable
Indwelling tube outflow, leaks with sheet or patient, not only pollutes, be also easy to cause the superinfection of urinary organ, with
And cause patient's mood impatient.
4. multiple flushing and medicine-feeding are carried out to bladder daily, although indwelling tube can be reduced when patient uses not
It is suitable, but when the connected instrument of plug repeatedly, apparatus, appointing can so drive indwelling tube to pull patient body, secondary damage be present
Hidden danger.
5. the treatment in pair affected part is a process lasting for a long time, it is necessary to a kind of improved equipment, then improves using effect
While, production cost, use cost and maintenance cost are reduced as far as possible.
In summary, it is necessary to check the actual conditions of Clinical practice, there is provided a kind of simpler, easy-to-use, cheap medical auxiliary
Help apparatus.
