Two-chamber is towards haustorium
This utility model belongs to a kind of fluid passage utensil, particularly a kind ofly is used to wash or the medical irrigation and drainage utensil of drain.
At present medical institutions in operation, postoperative need be to body cavity drain while washing, or in the medical treatment at the drain of vomica sinus tract while washing, and some single chamber irrigation drainage tubes can not overcome the problem from self-pollution, some two-chamber drainage tubes lack flushing or the drain that the Flow-rate adjustment gauge tap is controlled two tube chambers respectively, to such an extent as to it is very inconvenient to carry out irrigation and drainage in the above-mentioned curative activity, but still there is not corresponding suitable devices at present
Summary of the invention:
At the deficiency that exists in above-mentioned, this utility model is to address the above problem the technical scheme that is adopted to be: the purpose of this utility model provides a kind of medical two-chamber flushing aspirator, it is made of two fluid passage tube chambers and switch flow controller, can wash respectively simultaneously and drain.It both can use in operation, also can be after surgery or when non-surgical procedure vomica or sinus tract in use.The concrete scheme that is adopted is:
1, on the basis of original single tube drainage tube, becomes two-chamber or the two-tube fluid passage of separating for mutually, can wash at the same time or separately and drain.
2, on the double lumen passage, be provided with and control the flow of a certain single-lumen passage and the controller of switch respectively.
This utility model is by having the double lumen design of gauge tap, avoid the single-lumen product from body pollution, can regulate and control, accurately regulate simultaneously flushing or drain in the curative activity arbitrarily, on one side can again can the while drain when washing.
Description of drawings:
Below in conjunction with drawings and Examples this utility model is further specified.
Accompanying drawing 1 is a structure principle chart of the present utility model: wherein 1. syringe pipes (feed tube) body inner segment, 2. drainage tube (drain pipe) body inner segment, 3. switch controller, 4. flush switch, 5. drain switch, 6. syringe pipe (feed tube) is external section, and 7. drainage tube (drain pipe) is external section.
Accompanying drawing 2 is structural representations of the another kind of typical-sample of drainage tube (drain pipe).Among the figure 8. is one and can plugs in drain body inner segment root, (or plugging on controller), the termination has the porous drain body of sieve shape inner segment sleeve pipe, and purpose is the foreign material that liquid flow carries in the filter tube.
Specific implementation method
This equipment comprises two-chamber (or two-tube) the fluid passage 18.104.22.168. of mutual separation, has switch controller 3. two parts of regulating traffic engineering capability.Flush switch 4. and drain switch 5. are arranged on the switch controller, control syringe pipe (feed tube) 1.6. and drainage tube (drain pipe) 2.7. respectively.
Two-chamber (or two-tube) fluid passage again split inner segment (switch controller before part) 1. and 2. and external section (switch controller and later part) 6. and 7. two parts.
The body inner segment divides two types of flexible tube (flexible pipe) and stereoplasm tubes, and the tube wall of body inner segment two tube chambers merges (two-chamber) or constraint (two-tube) mutually mutually.Except easy single port, environment for use for easy generation plug-hole, attract head can also make bilateral hole, many side openings (2 in the accompanying drawing 2), sieve shape porous (2 in the accompanying drawing 1), also can plug on the switch controller handle with one in overcoat, head end has the porous sleeve pipe 8. of sieve shape and prevents that drain from stopping up the attraction hole of drainage tube (drain pipe).
Then part company with each other for external section, feed tube 6. tips connect flushing liquor; Drain pipe 7. tips connect (siphon) drainage bag (bottle) or vacuum extractor (bottle).Wherein feed tube can (be equipped with perforator, thrust in the aseptic transfusion bag (bottle)) and connect flushing liquor and carry out gravity flush; Also can connect air pump and carry out pressure flush; Also syringe be can connect, manual injection's medicine or flushing liquor carried out.
According to the position characteristics and the cost consideration of type of surgery and needs drain, length, thickness and the material of flushing suction catheter can have different specifications, and different class is also arranged on the complexity of switch controller.
Compare with present other drainage tubes, increase the function of flushing, cost is extremely low, but can wash simultaneously and drainage fully, The different auxiliary facility of arranging in pairs or groups can also provide manual flushing, gravity flush, pump pressure flush, syphon drainage, negative pressure drainage, The various ways such as strong vacuum suction have satisfied the actual needs that attracts while washing, and have stopped again the problem of single lumen catheter from body pollution.
The utility model is simple in structure, and is convenient and practical; With low cost, convenient operation is a convenient and practical good method
