Description

A kind of distributing anti-clogging abdominal thermal infusion drainage tube

Technical field

The utility model relates to medical instrument, specifically a kind of distributing anti-clogging abdominal thermal infusion drainage tube.

Background technique

Prepare the patient of row abdominal thermal infusion, abdomen pelvic cavity it is postoperative it is general need to up and down under symmetrically placed perfusion tube to diaphragm and Basin bottom makes heat perfusion liquid full of abdominal cavity, general to place 4.More drainage tubes, can the effectively full abdominal cavity of lavation, drainage it is thorough.But More drainage tubes are placed, patient suffering, wound and infection risk are not only increased, also do not meet theory minimally invasive at present.Second The common plugging for being a risk that abdominal thermal infusion pipe: heat perfusion patient puts pipe, but the necrosis of postoperative abdominopelvic cavity after generally performing the operation Tissue occlusion and Adhesion formation may cause blocked drainage tube, or tumour wrapped is formed around drainage tube, lead to hot filling Infuse unsmooth, i.e. possible plugging in general postoperative 3 days.

Abdominal thermal infusion pipe is not suitable for doing Preserving time at present, and Preserving time has the risk of plugging and infection, and patient stays More conduits are set, the senses of discomfort such as pain, friction are strong, and general place is no more than 1 week.The trouble of mucous tumor of ovary and peritoneal myxoma Person, extensive abdominal cavity adhesion easy to form and lead to intestinal obstruction；Such patient's post-operation adhesion is easy to send out again, and adhesion is continuous between intestinal tube It aggravates to induce bowel symptoms.These patients are suitble to place the anticlogging peritoneal lavage pipe of Preserving time, pass through the grape of heating Liquid glucose lavation repeatedly can dissolve or be partly dissolved myxoma, inhibits lesion progress, alleviates bowel symptoms.

The fixation of drainage tube is tied by suture at present, and knot, which loosens and drains infection etc. around nozzle and all may cause, draws The de- pipe of flow tube, leads to treatment failure.

Utility model content

To overcome many deficiencies in the prior art, the utility model provides a kind of distributing anti-clogging abdominal thermal infusion and draws Flow tube, only one pipe enter abdominal cavity, can be applied to oophoroma, mucous tumor of ovary and peritoneal myxoma, carcinoma of endometrium, knot The thermo-chemotherapy and intraperitoneal chemotherapy of a variety of abdominopelvic cavity tumours such as intestinal cancer.To realize the purpose, the technology that the utility model is taken Scheme is:

A kind of distributing anti-clogging abdominal thermal infusion drainage tube, including it is placed on that left and right under abdominal cavity diaphragm is one each, basin bottom is left Right each double channel catheter, the double channel catheter have drainage lumens, rinse chamber, the end of the double channel catheter it is tapered and close at Round and smooth bullet opens up the rinse mouth communicated with the Zhi Chongxi chamber on the bullet；It is described double above the bullet Two opposite draining holes communicated with the drainage lumens are opened up on cavities conduit pipe；It is characterized by also including general pipeline, described in four The upper end of double channel catheter is linked together with the lower end general pipeline in the distribution of " ten " font, is justified around it for setting four in the general pipeline The equally distributed main flushing chamber of the heart draws positioned at the main flushing chamber outer layer and around equally distributed four masters in the center of circle of the general pipeline Chamber is flowed, the described four main lower ends for rinsing chamber are communicated with the flushing chamber of four double channel catheters respectively, four main drainages The lower end of chamber is communicated with the drainage lumens of four double channel catheters respectively；The upper end of the general pipeline be arranged four respectively with institute State the flow sub that main drainage lumens communicate, four flush-through connections communicated respectively with the main flushing chamber.

Further, the tube wall of the general pipeline includes opening up the main internal layer for rinsing chamber and main drainage lumens, and described interior The combined latex outer layer of layer, the center of the internal layer also open up inflatable chamber, the upper end of the general pipeline also set up with it is described The gas-charging connection that inflatable chamber communicates, the interior setting of the gas-charging connection is from close valve, in one section of latex close to the lower end general pipeline Layer is not bound with together with one section of latex outer layer but is separated from each other to form gap, is arranged on this section of latex internal layer 202' Communicate and avoid the main outlet chamber for rinsing chamber and main drainage lumens with the inflatable chamber, the outlet chamber be opened on it is described between Gap；There are this section of latex outer layers after air or liquid that pressure is higher than atmospheric pressure to expand shape in the inflatable chamber and outlet chamber Circularize capsule.

Further, it is 12 mm -16mm, institute that the outer diameter of the double channel catheter, which is the outer diameter of 4 mm -6mm, the general pipeline, The major diameter for stating the internal diameter of drainage lumens and main drainage lumens is 3-5mm, minor axis 2-3mm, described to rinse chamber and the main major diameter for rinsing chamber For 1-2mm, minor axis 0.5-1mm.

Further, the settable anti-one-way valve backflowed in the drainage lumens and/or main drainage lumens.

Further, each flow sub and flush-through connection have the identification strip of same color, that corresponding pair Identification strip of the cavities conduit pipe with same color.

Compared with prior art, the utility model has the following characteristics:

1, double channel catheter top round end designs, and avoids injuring abdominal organs；

2, the more side opening designs of double channel catheter, drainage is unobstructed, avoids blocking；

3, double channel catheter is built-in rinses chamber, and blocked drainage tube can effectively be prevented by going out liquid through flushing chamber；It is passed through after blocked drainage tube Flushing chamber, which goes out liquid, has larger probability to lead to again；

4, the utility model distributing conduit, dividing into abdominal cavity rear tube one is four.Four (drain) out into (flushing) four, rinse And drainage is thorough.And can be exchanged according to actual conditions are as follows: 1., two drainage lumens as inlet tube, in addition two drainage lumens are as going out liquid Pipe, four flushing chambers are only used as to rinse anti-clogging；2., two rinse chambers and the different situations such as go out into, two stomach walls symmetrical drainage lumens.Foundation Drainage needs, irrigation flow needs, chemotherapy perfusion needs and the easily different conditions such as stopping state can be adjusted.

5, the utility model reduce across stomach wall pipe quantity be it is minimum, only general pipeline directly contacts the external world can be as far as possible It avoids pollution, stimulation peritonaeum and internal organs in catheter retaining body is effectively reduced and induce uncomfortable risk.

6, general pipeline is pierced by stomach wall and switchs to single drainage tube, avoid pain caused by indwelling multitube from aggravating, infection risk increases and It nurses cumbersome, meets minimally invasive theory；

7, anti-design of backflowing can be done, external list drainage tube indwelling is conducive to set pipe for a long time；

8, into expanding behind abdominal cavity for mushroom head sampling device, it can effectively avoid de- pipe, it when necessary in vitro can be only with fixed patch It is fixed, it is tied without silk thread；Mushroom head is furthered to be tensioned to and is adjacent to peritonaeum, sepage around drainage nozzle can be effectively prevent.

9, this drainage tube can be changed to two double channel catheters according to the actual situation, into abdominal cavity after be divided into two independent tubes.
