Description

Disposable intracranial hematoma strand attracts the stream device

This utility model relates to the medical apparatus and instruments that a kind of disposable intracranial hematoma strand attracts stream.The treatment of intracranial hematoma influences minimum Therapeutic Principle from safe and effective to patient, more and more hinders direction to microinvasion Wicresoft and develops.The intracranial hematoma of a variety of causes comprises that original wound strike is excessive, and the old patient who is difficult to bear big operation of opening cranium then can bear Wicresoft's intracranial hematoma strand attraction stream treatment, thereby obtains to save the chance of life.The use of medical apparatus and instruments requires disposable use day by day, and is promptly convenient, can avoid cross infection again.The patient of intracranial hematoma particularly, the state of an illness is critical urgent, is badly in need of eliminating hematoma and saves life, alleviates sequela.This class patient implements to perform the operation to the operating room of conditions being possessed, and often delay treatment is even not possible, need carry out instantaneity Minimally Invasive Surgery under bedside or the CT.At present, this class operation is progressively carried out, but does not also have a kind of operational simple and direct, practical disposable Wicresoft intracranial hematoma strand to attract the stream device, causes to have inconvenience in the operation.

The purpose of this utility model provides a kind of disposable intracranial hematoma strand and attracts the stream device.Its population structure is small and exquisite, and the collection strand attracts stream for one, and is cheap, simple to operate, safe and practical convenience.

This utility model revolves the strand device by strand sucker body, tube core, miniature electric and the adjustable pressure limiting drain valve is formed.The strand sucker body is a hollow tubular, and front end is inserted intracranial part and is divided into rustless steel and makes caliber 3-5mm, length 35-80mm when using.According to inserting the degree of depth that intracranial arrives the hematoma center, select suitable length, in order to avoid longly cranium outside, expose unfavorable fixing.The body rear end is a soft pipe cap, and pipe cap is made by rubber or transparent plastic, trumpet type, and osculum end hard-pressed bale stainless steel tube 2-3mm, and bonding with it, big opening end coupling motor revolves strand device axle outer tube and inserts.The attached cork lid of big opening end is used to clog big mouthful.It also is trumpet type that there are side pipe, side pipe opening in the pipe cap middle part, edge attached plug mouthful soft lid.Connect adjustable pressure limiting drain valve or other aspirators by side pipe.Tube core is made of plastics, and also available transparent organic glass is made, and cylinder slightly is longer than body behind the insertion strand suction pipe, and the blunt circle of front end plays sealing strand suction pipe effect and prevent to twist injuring cerebral tissue or blood vessel when suction pipe is inserted intracranial., can peep and the variation of front end color and luster in conjunction with light source with the printing opacity tube core, judge whether enter hematoma.The electronic motor that revolves the strand device is by the power drives of general miniature cocurrent electromotor by 1.5-6v.Motor is fixed in the plastic chamber of a sealing, and air and liquid all can not enter intracavity.One end of motor reel protrudes outside the plastic housing, revolving silk with rustless steel spiral shell strand is connected and drives hank knotting, the motor reel that protrudes plastic housing has an annular central siphon outward, this central siphon is the part of plastic housing, its effect is to cooperate with pipe cap when revolving the revolving silk and insert the strand suction pipe of strand device, avoid liquefied gas to leak through this junction, it is not interrupted to guarantee that simultaneously the pipe built-in motor drives the hank knotting rotation.The adjustable pressure limiting drain valve is a hollow tubular, is made by transparent plastic.Caliber 6-12mm.Valve pipe front end has a preceding hole, is connected with strand Straw cap side pipe.Managing a built-in front end has the spring of annular sharp medicated cap, and sharp medicated cap is made by rubber, and the medicated cap point supports preceding hole, and the elastic force by spring seals preceding hole.If hydraulic pressure is greater than spring force in the preceding hole, liquid then can flow out through side opening in the pop-off cap point inflow valve.The valve plug at rear portion in the valve pipe is supported at the spring rear portion.Valve plug is made by rubber, and its effect is draught excluder pipe rear end, avoids liquid to flow out.The valve gap that the valve plug rear portion is connected with valve plug is the female thread lid, and valve pipe rear portion has external screw thread to cooperate with it, and the spinning in and out valve gap drives the valve plug advance and retreat, and with the elastic force of this regulating spring, it is intrinsic pressure to control preceding hole, guarantees not excessively drain.Therefore it is applicable to that liquid will guarantee certain intrinsic pressure controlled drain in the various body cavitys.

This utility model is suitable under bedside, the CT indication, uses in the operating room, particularly emergent the use.The hematoma drain can be used for, also the tricorn drain can be advantageously used in.During clinical use, deep boring is earlier inserted tube core in the strand suction pipe, can insert to the intracranial hematoma direction through boring.Reach the hematoma center, extract tube core, visible kermesinus liquid flows out, and covers the back port lid, aspirates through side opening.Suction be difficult for or output much smaller than the calculated in advance amount, the hematoma in bulk that condenses is described.Insert electronic revolve strand device by metapore this moment, pulverizes clot by revolving strand, from the side opening suction, reaches 2/3rds of quantity of hematoma until the sucking-off amount simultaneously, extracts and revolve the strand device, and the sealing metapore connects the adjustable pressure limiting drain valve from side opening, gets final product constant drainage.Also can wash hematoma, inject hemorrhage or blood coagulation dissolving medicine, wash again through side opening.

Use this utility model, the strand suction pipe enters hematoma, and the suction of suction strand, douche and injection and drain are all carried out through this pipe, has avoided repeatedly intracranial to intert injured brain tissue, and wound is slight, the low good effect of expense, and patient and family members are easy to acceptance.The adjustable pressure limiting drain, the a series of troublesome operation for keeping the intracranial normal air pressure to carry out in the postoperative drainage process have been reduced, the excessive drain that more can avoid the siphonage of drainage tube in the drain process in the past to cause bring infringement, also reduced patient's head position restriction.Disposable using apparatus greatly facilitates patient's use under different condition whenever and wherever possible, thereby wins valuable opportunity for saving patient.
