Description

Be used for applying and removing equipment and its use of locking device in peritoneal dialysis from the tube element end
Technical field
The present invention relates to wherein must under the condition of controlled pollution, to carry out those fields with " locked in " operation of opening of tube element, for example health field, particularly nephrology field or the operation in clean room, carried out.More particularly, the objective of the invention is to improve the patient's who carries out peritoneal dialysis method of attachment.
Background technology
Subject matter in peritoneal dialysis treatment is infection problems: their common result be in hospital, owing to stop (the abandoning) of pyemic peritoneum " consumption " and method.
And, so far, still do not have perfect " antipollution " apparatus: German company FreseniusMedical Care has introduced disposable peritoneum and has changed apparatus, but this is with respect to the replacing in artificial removable peritoneal dialysis (CAPD), stays the window of about 50% latent infection pollution risk.
Because the mobile therein pipeline of dialysis solution is aseptic and disposable, thus this danger and described pipeline be connected and two moments of disengagement interrelate.
The various schemes that propose in manufacturer by the equipment that is used for peritoneal dialysis, mention Fresenius Medical Care, the said firm attempts by designing a kind of locking device that is called " pin " (a kind of sealing-plug with O-ring seals) here, and the risk of pollution of elimination during connecting, the disposable cylindrical apparatus with operating grip is shifted the intracavity of peritoneal catheter onto in peritoneal dialysis circulation end.Because this takes place under conduit is connected to situation on the apparatus, so at peritoneal catheter during with the apparatus disengagement, antibacterial, virus and other contaminated materials can not enter in the conduit.Yet, before being connected on the new disposable apparatus that new loop ends pin is housed, before the next circulation of beginning, must extract exhausted pin from the end of conduit.In a single day this extracting by means of the suitable stopper with retaining clip carried out, and this retaining clip is screwed on the end of conduit, hooks exhausted pin, and unscrews, just extract it.This operation is carried out in opening wide air by patient's hands, equally he is exposed among risk of pollution and the more serious peritonitis danger.
Another kind of apparatus is described in patent US 6,485,483.Other apparatus that is used for peritoneal dialysis of contaminated solution problem is at US 5,221, and 267, describe among DE 10042067, US 5,336,173, EP0 092 528, US 4,950,230 and the GB 2 134 202.
The present invention is arranged to eliminate fully or substantially peritonitis danger to the purpose of itself.
Because the selection of method still submits to urgent social condition, so patient for low social economy level (health is short of, is not enough to provide residential area, insufficient educational level or the bad state of alert relevant with the age in " controlled pollution " district), this method does not relate to the method safety owing to mainly relevant with patient's condition, so be under an embargo easily.
Target should rather than realize on the patient in apparatus: because peritoneal dialysis is a kind of health-care method for the more common problem of statistics in third and fourth age, thereby when patient's compliance-on physiology and in relatively poor mentally-usually, we should not consider patient's effect when the target of simplicity of planning aseptic, use and safety.All targets should be realized by apparatus itself.
Therefore still feel to have huge needs for the adapter that is used for artificial removable peritoneal dialysis, this adapter guarantees the aseptic in the manipulation operations of dialysis apparatus, use easily,, and do not require professional's help particularly for the patient of the very flexible and/or the low health level of training.
Summary of the invention

Apparatus according to the present invention is characterised in that, a kind of sealing (preferably sealed) device, this device moves in the apparatus, thus it not with contact on every side and keep aseptic characteristic.
Because its characteristic; apparatus according to the present invention is provided at not under the protection environment with external communications and changes being connected between the bag at the far-end of peritoneal catheter with peritoneum, make antibacterial, fungus, virus, and any other contaminated materials can not pollute the inside that apparatus is changed in the end of peritoneal catheter or inside or peritoneum.
Because its design characteristics can be understood by patient easily and intuitively according to the mode of devices work of the present invention, thereby in fact might save training by the technical staff.Particularly advantageously be, apparatus also can be used by the blind person, uses in originally on one's body suitable indication of apparatus.
Apparatus of the present invention also can provide and make its function (for example, be used for each operating position, cycle stage unidirectionally advance, the mechanical caging apparatus of unexpected mechanical blockage of throwing off) of " anti-wrong ".
Another advantage is that the cost of disposable apparatus is fully comparable with the most current cost of being born by the patient who carries out peritoneal dialysis.
Because below with the characteristic of describing, in fact eliminated taboo according to apparatus of the present invention, and overcome the restriction of registering peritoneal dialysis for patient candidate who shows physiology, spirit or social defective for the peritoneal dialysis technology relevant with the social environment problem.
Therefore claim 1 is purpose of the present invention with the apparatus that its dependent claims is limited.

With reference to Fig. 2, Fig. 2 is the cardinal principle longitudinal cross-section by the plane A-A of the apparatus of Fig. 1, the inside of this expression container 1.Hollow container 1 has bottom 16 and perimeter wall 17 substantially, and this bottom 16 and perimeter wall 17 are delimited cylindrical interior chamber 18 with lid 4.Rotation platform 19 is installed in cylindrical chamber 18 inside, preferably near bottom 16.For easily manufactured, advantageously, container 1 is columniform, as rotation platform 19, but does not get rid of other shape, even for same internal chamber 18.
Platform 19 centrally has boss 20 below its base, this boss 20 is assemblied in the blind hole 21, and this blind hole 21 is formed in the bottom 16 of container accordingly.Platform 19 has unitary pin 22, and this unitary pin 22 is stretched out through the through hole 23 built in it from the lid 4 of container 1.Handle 5 is fixed on the pin 22, thereby by the artificial effect on handle, platform 19 can be with respect to the inner lateral surfaces rotation of container, and this inner lateral surfaces is by 24 indications.Because during manufacture assembly problem, be connected on the pin 22 that stretches out from lid by means of the handle 5 that is threaded of part, fixed with lock definitely then.Nature, local melting by pin 22 and handle 5 or bonding can provide fixed optional form, and condition is that the material that constitutes these parts is plastics as suggestion.
One end of handle 5 arrives point 25, and point 25 is used to indicate the position of the particular element of the position, particularly rigidity of rotation platform apparatus mounted thereto.
Also with reference to Fig. 3,4,5,6 and 7, the described element that rigidity is installed on the rotation platform 19 comprises: admit housing 26, it can admit and keep first locking device 27 extracted from the end 13 of tube element 3; With release housing 28, after first locking device 27 had been extracted, it can comprise and discharge second locking device 29 in the end 13 of tube element 3.Admit and discharge housing 26,28 to be radially positioned on the platform, and have the opening of the passage of the inner lateral surfaces 24 that is used for locking device turning containers 1.In the embodiment that describes, housing has longitudinal axis, this longitudinal axis also with exterior side surfaces quadratures by 40 indications.For the sake of clarity, locking device 27,29 is not cut open in the drawings.
Locking device 27,29 can be identical, and comprises tip 30 and the tail end 31 relative with the tip, and this tip 30 plans to be received in the end 13 of tube element 3.
Suitably the tip 30 of taper has the top formula shape of the end that is used for being inserted in the cylindrical tube linear element, although the drain cross section and other therefore most advanced and sophisticated shape.
First circumferential groove that is used for O shape circle 32 is provided at tip 30, to create fluid-tight in the joint of tube element 3.
Locking device 27,29 preferably has cylinder 33 substantially, although it can have other shape.Second circumferential groove that is used for O shape circle 34 is provided at cylinder 33.And, still on the side surface of cylinder 33, periphery recess 35 being arranged, this periphery recess 35 preferably stops in the close undercutting 36 of tail end 31.The function of various piece will be become clearly by the remainder of describing.
With reference to Fig. 3, Fig. 3 is the cross section according to the embodiment of apparatus of the present invention, this expression platform 19 with Fig. 2 in apparatus in the corresponding position, position represented.
Thereby the configuration that discharges housing 28 is that its longitudinal axis parallels with the main shaft of handle 5, and is positioned on the quadrant of being represented by lid 4, in the position of reference mark 6.Admit the configuration of housing 26 to be, the main shaft of its longitudinal axis and handle 5 is perpendicular, and is positioned on the quadrant of being represented by lid 4, in the position of reference mark 7.
Should be appreciated that it is not binding that orthogonality described above is arranged, and the axis of two housings 26,28 can form the angle except that the right angle between them.Only importantly, anyone who sees container from the outside can both understand that one of locking device when or another housing 26,28 are coaxial with the end 13 of tube element 3 in such a way, thereby the tip 30 of locking device 27,29 is also coaxial with it.
Detailed inspection is admitted and is discharged housing 26,28, can see that they differ from one another, even both have and the corresponding shape of the shape of locking device.Admit housing 26 to have the preferably holding device of the form of circumference fin 37 in inside near its bottom, this circumference fin 37 is given prominence in admitting housing 26 and to its bottom angled.When locking device 27 is received in when admitting in the housing 26, as seeing later on, 37 plans of circumference fin are inserted in the periphery recess 35 of locking device 27 and with the latter's undercutting 36 and engage.
