Description

Medical negative pressure drainage appliance

This utility model relates to a kind of medical wound negative pressure drainage device, and particularly a kind of spheroid negative pressure of can replenishing can directly be washed soiling solution in the spheroid, observes very convenient again wound negative pressure drainage device.

Outside the crimson blood of various patients after surgery, the necessary lead body of sepage, to guarantee wound healing.But the past generally adopts volume bar Cotton Gossypii or rubber tube (connecting vial) to be used as drainage equipment.Because the drainage technology of this backwardness not only consumes dressing such as a large amount of Cotton Gossypiis, gauze, brings patient's misery again, increase medical worker's workload, as deal with pus and blood improperly and also can pollute sheet, bedding; Because vial is not only easily broken, volume ambassador patient is handicapped, and owing to be open, causes retrograde infection easily, and delay treatment is not so meet medically aseptic requirement.

A kind of known rubber system " wound negative pressure drainage device " is improved according to the negative pressure drainage device of U.S.'s invention, and it has replaced the backward technology of volume bar Cotton Gossypii and rubber tube drain, and above-mentioned disadvantage is overcome.But it also has these defectives: because it has only liquid outlet not have air vent, spheroid will produce negative pressure to be had only by liquid outlet and replaces finishing.Like this, can occur the insufficient phenomenon of negative pressure unavoidably in the drain process, must give in time to replenish, but because contain soiling solution in the spheroid, replenish negative pressure must first discharge opeing, so pretty troublesome; Owing to there is not air vent, discharge opeing can only just make soiling solution flow out from liquid outlet by squeezing a pinch spheroid, and like this, the soiling solution during crowded pinching in the ball is contaminated check valve probably, and is extremely unhygienic; Owing to there is not air vent, can't directly wash the intravital hydrops of ball, can only lean on liquid outlet to absorb water repeatedly to squeeze and wash, so clean very difficultly, and squeeze and wash the damage that easily causes spheroid; Because of suspension ring are the next doors that are fixed on spheroid, the both difficult direction of hanging of selecting spheroid during use makes spheroid hang posture again easily and tilts again, cause the outer graduation mark of interior soiling solution of ball and ball not become parallel, like that, just can be certain about after must be when observing drainage flow with hand steered positive spheroid, very inconvenient.So these defectives all must try every possible means to remedy.

The purpose of this utility model is that a kind of new negative pressure drainage device will be provided.It is convenient to make its not only replenish negative pressure, and discharge opeing needn't be squeezed and be pinched a spheroid, direct soiling solution in the bulb syringe again, but also can select the direction of hanging of spheroid arbitrarily, it is honest that spheroid is dangled, the convenient correct capacity of observing the interior soiling solution of spheroid.

This utility model is achieved in that a kind of new negative pressure spheroid of design, three mouths are arranged on it, there are inlet and air vent in the upper end, there is liquid outlet the lower end, promptly connects an air vent plug on air vent, when needs replenish negative pressure, air in the spheroid is discharged from air vent, first-class subsequently air vent plug can obtain competent negative pressure, no matter whether the contain soiling solution all need not be employed liquid outlet in the spheroid; When wanting discharge opeing, air vent plug and liquid outlet plug all to be opened, soiling solution just can flow out automatically in the spheroid, need not squeeze and pinch spheroid, guarantees that check valve is not contaminated; In the time will washing in the spheroid soiling solution, can directly pour water into from air vent, soiling solution just can flow out from liquid outlet with water, and it is quite easy to clean; On union joint, be with and turn to active suspension ring, make spheroid choice direction arbitrarily when hanging well, suspension ring are enclosed within on the union joint that is in ball centre, make the spheroid that dangles straight down, can not tilt again, soiling solution is parallel with the graduation mark outside the ball in the ball, so, needn't remove to set upright spheroid by the reuse hands when observing capacity, like this, can be not only convenient but also correctly write down blood volume and sepage amount, the back is observed and the replenishment of blood content form the basis in order to perform the operation.Below with reference to accompanying drawing utility model is described in further detail.

Fig. 1 is a kind of longitudinal sectional view of known wound negative pressure drainage device.

Fig. 2 is the longitudinal sectional view of this utility model off working state.

Fig. 3 is the longitudinal sectional view of this utility model duty.

With reference to Fig. 2, this utility model is by two most compositions of drainage tube and negative-pressure container: made by silica gel for one, profile is flat, in pipe (1) in the body of three stringer ridges is arranged, by glueing joint pipe (2), be fixed together with external pipe (3), triplicity becomes the whole piece drainage tube.Here, the tube wall of pipe has 30 of conduction holes in the body, and the union joint (4) that the other end of external pipe (3) can be covered (10) upper end with negative pressure is connected.Union joint (4), inlet (5), air vent (7) and negative pressure lid (10) four are an integral body, when this body and compacting ring (11) and spheroid (12) when closely combining, become a negative-pressure container.Suspension ring (6) are enclosed within on the union joint (4), and its higher authorities have individual annular distance, the sick bed limit that hangs over capable of hoisting, and suspension ring (6) are movable, can do turning to of 360 deg, making spheroid hang direction can choose at random.Air vent plug (8) is enclosed within on the air vent (7), regulates the interior soiling solution of negative pressure and bulb syringe and all uses air vent (7) to finish, and when spheroid (12) produced negative pressure, its guaranteed can not leak gas.Inlet (5) is in the tube chamber of union joint (4).Check valve (9) is arranged on the lower end of inlet (5), and it is made with silica gel, can bear certain pressure, and sealing property and one-way performance are good, can prevent that soiling solution and air from flowing back in the human body.Soiling solution flows through inlet (5) and check valve (9) enters in the spheroid (12) from drainage tube.Here, spheroid (12) is made for translucent silicone rubber, can observe interior drainage flow of ball and soiling solution color and luster, character, and the graduation mark (13) of spheroid (12) appearance is used for the record drainage flow, spheroid (12) had both played the effect that produces negative pressure, and double as storage liquid is used again.Liquid outlet (14) is arranged on the lower end of spheroid (12), and both are same one.Liquid outlet plug (15) is enclosed within on the liquid outlet (14), when spheroid (12) storage liquid, clogging with it that liquid outlet (14) guarantees not can seepage, liquid outlet plug (15) and air vent plug (8) are all opened, soiling solution in the ball promptly can flow out automatically, also can directly pour water from air vent (7) and wash soiling solution in the spheroid.This device result of use ideal.

During use, earlier this device is sterilized, before sew up wound, pipe (1) in the body is trimmed to suitable length, being embedded in needs the drain position, and conduction hole must not be exposed external, seam one pin on skin, the weld of fixing pipe (1) in vivo and external pipe (3), external pipe (3) is plugged union joint (4), opens air vent plug (8), pinch flat spheroid (12) with hands, air is discharged, and then air vent plug (8) beyond the Great Wall unclamps behind the hands and promptly forms negative pressure in the spheroid (12), slowly sucking-off of crimson blood sepage with in the wound hangs over the sick bed limit with this negative pressure spheroid then.If the spheroid of small dimension, patient's WA can be placed on spheroid (12) in the pocket and take away.If find the negative pressure deficiency during drain, can open air vent plug (8), will retain air in the ball and discharge, top plug more immediately can recover the attraction function of spheroid (12) again.If drain liquid is more, after then in ball, being full of, write down drainage flow by spheroid EXT scale line (13), just can open liquid outlet plug (15) soiling solution in the ball is discharged, top plug continues to attract then; If drainage flow is few, then write down once every day.General application patient changes negative-pressure container once every night, and it is reusable after washing and sterilizing.Drainage tube is to pull out when a patient finishes using again, and cleaning and sterilizing need not often be changed then, to reduce medical care precess and patient's misery.Also can be with drainage tube as disposable, promptly each patient change one brand-new, to guarantee medical safety.
