Abstract
The utility model provides a sealed negative-pressure bidirectional drainage tube which belongs to the field of medical instruments. The sealed negative-pressure bidirectional drainage tube comprises a medical sponge and a drainage tube pre-buried in the medical sponge, wherein the two ends of the drainage tube are open and extends out of the medical sponge; and plugs are arranged on the openings at the two ends of the drainage tube. When the sealed negative-pressure bidirectional drainage tube is used, the medical sponge is placed on a wound surface, and the wound surface is sealed with a sticky sealing membrane; and the opening at one end of the drainage tube is opened, and a negative-pressure device is adopted for performing drainage. In order to prevent the drainage tube from blockage, irrigating liquid is injected into from the other end of the bidirectional drainage tube. For a wound surface that is particularly liable to drainage tube blockage, the drainage direction is exchanged regularly (namely bidirectional drainage), so as to achieve the effects of reducing drain sediment and improve the drainage efficiency.
Description
Technical field
This utility model belongs to medical instruments field, relates to a kind of negative-pressure drainage tube, relates in particular to a kind of closed negative pressure double take-off pipe.
Background technology
The closed negative pressure drainage therapy is emerging in recent years a kind of trauma care technology, has many-sided advantages such as efficient drain and decompression, infection, promotion wound healing and minimizing dressing change frequency, is called as the revolutionary advancement of trauma care.One of its core technology is that the porous drainage tube is placed the polyvinyl alcohol foam material, polyvinyl alcohol foam material and wound tissue are directly, contact fully, blood that wound surface produces or sepage etc. are introduced into foam under vacuum suction, be inhaled into again in the drainage tube, finally be excreted through drainage tube.Because big slightly organize fragment or the blood clot etc. of volume are blocked in outside the foamed materials, so the drainage tube phenomenon of blocking can not take place, this is one of difference of closed negative pressure drainage technology and traditional drainage method maximum.Yet in clinical application practice, the phenomenon of line clogging still happens occasionally.Reason is that the part wound surface is serious owing to infecting, and the rheuminess thing in the exudate is many, and the liquid thickness easily is deposited on tube wall.Especially drain is after 2～3 days, and drainage flow greatly reduces, and drain easily drying is formed a scab and blocking pipe.Because it is cecum that the traditional drainage pipe enters an end of foamed materials, promptly unidirectional drain, the secretions of drainage tube and incrustation etc. can not in time be discharged, thereby have influenced drainage efficiency and and drainage effect.
The utility model content
The purpose of this utility model is the drainage tube blockage problem that exists in the prior art in order to solve, and a kind of closed negative pressure double take-off conduit is provided.
Closed negative pressure double take-off conduit of the present utility model comprises medical sponge and the drainage tube that is embedded in the medical sponge.The both ends open of drainage tube wherein, and stretch out outside medical sponge.The both ends open of drainage tube is provided with plug.
This utility model has the following advantages with respect to prior art:
1, adopts the double take-off pipe, can squeeze into flushing liquor, carry out vacuum suction from opposite side from a side; Also aseptic tinsel can be probeed into drainage tube inside, further flushing again after tamper is disclosed out has thoroughly solved drainage tube and has stopped up the problem that the back is difficult for mediation.
2, both ends open all can be used as draining hole, can regularly change drain direction (being double take-off) to the wound surface of those easy especially blocking pipes, plays and reduces drain deposition, the effect that improves drainage efficiency;
3, naturopathy is combined with medication, further improve therapeutic effect.When one end of double take-off pipe was used as draining hole, the other end can be used as dosing mouth (for example adding antibiotics, somatomedin etc.); In addition, the part wound surface is at negative pressure drainage after a period of time, and the wound surface drying that becomes is chapped, and at this moment can add normal saline or other nutritional liquid from dosing mouth, thereby reaches moistening and nutrition wound surface, promote the effect of healing.

The specific embodiment
A kind of closed negative pressure double take-off conduit comprises medical sponge 1 and the drainage tube 2 that is embedded in the medical sponge); The both ends open of drainage tube 2, and stretch out at medical sponge 1.The both ends open of drainage tube 2 is provided with plug 3.
During use, medical sponge is placed on the wound surrounding tissue (wound face), with sealing adhesive membrane sealing wound face; Open the opening of drainage tube termination, adopt negative pressure device to carry out drain.
In order to prevent the gambling plug of drainage tube, regularly squeeze into flushing liquor by another survey of double take-off pipe.
Wound surface for easy especially blocking pipe is regularly changed drain direction (being double take-off), plays and reduces drain deposition, the effect that improves drainage efficiency.
As required, can add medicine (as normal saline or other nutritional liquid) by the opposite side by drainage tube, thereby reach moistening and nutrition wound surface, promote the effect of healing, realize that naturopathy combines with medication, further improve therapeutic effect.
