Abstract

The utility model discloses a medical dual-cavity flushing drainage tube, which can continuously and synchronously flush and drain brain hematoma. A thin flushing pipe is embedded in a thick drainage tube wall; the flushing pipe is opened on the outer side wall of a blind end on the most front part of the drainage tube; a side hole is not formed in the flushing pipe; a plurality of side holes are formed in the part, which is within 3 to 4cm from the part 0.5cm from the blind end of the drainage tube; the holes can be elliptical; and each hole is 3mm in the long axial direction and 2mm in the short axial direction. After the drainage tube is implanted in a hematoma cavity in a skull through operation, an infection focus can be continuously and synchronously flushed and drained by connecting the flushing pipe with an infusion apparatus and connecting the drainage tube with a drainage bag.

Description

Medical two-chamber irrigation drainage tube

Affiliated technical field

This utility model relates to a kind of surgery washing drainage system of treating pathological changes such as intracerebral hematoma.The synchronous flushing and the drain that continue have particularly been realized.

Background technology

At present, the removing of intracerebral hematoma aspect less invasive techniques, has soft passage and hard two kinds of apparatuses of passage.The design should belong to soft passage technology.But mostly present soft passage is single lumen catheter.Carry out the haematoma cavity flushing after the operation, injection, operations such as suction all need drainage tube is connected with three-way device.When carrying out aforesaid operations, all to carry out disinfection at every turn and in a kind of open relatively environment, operate.Increased the risk of infection and clinician's the amount of labour, and flushing, injection, operation such as drawing hematoma is to the rapid speed of intracranial pressure influence, and amplitude is also bigger.And on the opportunity of this operation, number of times reaches quality and receives clinician's energy, and the time, empirical restriction is bigger.Environment is also had certain requirements, and poor more its risk of aseptic condition is big more.Hard passage technology has been realized flushing and drain one, but the flushing of still being unrealized is synchronous preferably with drain, because of its drain caliber is thinner, is prone to clot stops up, and has only the hematoma liquid that liquefies preferably just can draw, and has clot or residual broken organizing then to be prone to be obstruction during like suction.This also is not very ideal to realizing removing as early as possible the target of hematoma compression.

Summary of the invention

In order to overcome single chamber drainage tube and hard passage technology; Inconvenience synchronous continual rinsing of fine realization and drain; Reduce the risk that open operation infects and reduce clinician's amount of labour and the speed that speeds the intracranial hematoma dissolving and discharge, in time dilute and take away the secreted inflammatory mediator of pathological tissues and reduce it to brain tissue injury, this utility model provides a kind of drainage tube; Under the prerequisite that does not increase thick conventional softer passage drainage tube external diameter, realize flushing and the drain synchronously of continuing to haematoma cavity.And provide more airtight mode of operation order to operate safer, more convenient.

This utility model solves the technical scheme that its technical problem adopted: thin soft syringe pipe is embedded in the thick soft drainage wall, and the two tube chamber is not connected.Syringe pipe is divided into embedded part and independent sector.Drainage tube is divided into parallel section and independent sector.The drainage tube front end is a cecum, and tail end is the interface that can be connected with the transfusion device nipple, from cecum side openning three rows in 3 centimetres backward, and arrangement straggly, syringe pipe place side is side openning not.The syringe pipe embedded part drainage tube cecum that goes directly is opened on drainage tube side outer wall, only opens flatly to get final product, and does not establish other side openings.Drainage tube still need join one with its internal diameter and the suitable hard metal tube core of length.Syringe pipe independent part tail end is made as the interface and the block that can be connected with the transfusion device nipple.And establish a simple and easy water in the syringe pipe independent part and end.Earlier syringe pipe and transfusion device and flushing liquor are connected the emptying air during operation.Then drainage tube is inserted haematoma cavity.After the completion, drainage tube is connected with drainage bag and also can pacifies into three-way device.Open transfusion device and syringe pipe water after connection is accomplished and end, suitable speed of adjustment.Like this, flushing liquor gets into focus after syringe pipe flow to the drainage tube head end, along drainage tube disperse on every side, after reaching certain pressure, promptly from side opening, flows into drainage tube then, draws cranium and flows into drainage bag outward.Just can control the height of intralesional pressure through the height of adjustment drainage bag position, that is, and the scope of may command flushing liquor effect.Suggestion, drainage bag upper limb position are higher than about 10.0 centimetres on operation plane.Cross that low then the flushing liquor sphere of action is little, directly flow away, lose the effect of its flushing focus from drainage tube.The too high flushing liquor that then may make amasss in cranial cavity in a large number, the danger that causes high cranium to press.Stop up drainage tube if any clot, can or directly crumb through short its discharge of extruding drainage tube, also can be through being connected in the three-way device between drainage tube and the drainage bag, suction flushing removing.With the treatment hematoma is example, and flushing liquor is chosen as the normal saline urokinase solution, carries out continual rinsing.And can consider, accomplish in 6 hours that the not Fei Shi that per hour gives urokinase 10,000～20,000 units adding flushing liquor drips in the kettle, to quicken the dissolving and the removing of hematoma in operation.

The beneficial effect of this utility model is: can realize synchronous flushing and the drain lasting to intracerebral hematoma, thereby accelerate the speed that the intracerebral hematoma dissolving is dissipated, help removing as early as possible its compressing to cerebral tissue.Can alleviate clinician's the amount of labour, make operation easier.And operation under the better state of a kind of airtight condition, it is aseptic that operation more is easy to do, safer.Influence to intracranial pressure is also comparatively mild, has avoided significantly fluctuation.
