Kontor for Industriel Eneret v. Svend Schønnlng.___________ (64) Blodtøraningsmanchet.Office of Industrial Rights v. Svend Schønnlng .___________ (64) Blood Drying Cuff.

Den foreliggende opfindelse angår en blodtømningsmanchet til anvendelse ved tømning af ekstremiteter for blod forud for et operativt indgreb og omfattende et antal seriekoblede sektioner indrettet til at optage og tilbageholde et gasformigt medium, samt et antal ventiler, som forbinder de nævnte sektioner. En sådan manchet er kendt fra beskrivelsen til dansk patent nr.47175.The present invention relates to a blood emptying cuff for use in emptying extremities of blood prior to an operative procedure and comprising a number of series-connected sections arranged to receive and retain a gaseous medium, as well as a number of valves which connect said sections. Such a sleeve is known from the description of Danish patent no. 47175.

Ved den kendte manchet er sektionerne gennem slanger forbundet til et styreorgan, med hvilket man er i stand til at sætte kamrene under tryk et efter et. Dette kendte apparat er videreudviklet i det i beskrivelsen til U.S.A. patent nr. 2044.691 viste apparat.In the known sleeve the sections are connected through hoses to a guide means with which one is able to put the chambers under pressure one by one. This known apparatus is further developed in that described in U.S. Pat. patent No. 2044,691.

Til dette apparat er der mellem sektionerne indrettet forbindelseskanaler udstyret med en drøvleventil. Ved det videreudviklede apparat søger man at opnå en automatisk regulering af den successive oppustning af sektionerne. Begge disse manchetter er behæftet med forskellige ulemper. Det første apparat fordi den manuelle be- 141352 2 tjening af reguleringsventilerne kræver stor øvelse hos operatøren, der betjener apparatet, og det videreudviklede apparat ved at drøvleventilerne vil sikre, at oppumpningen sker successivt, men fratager operatøren mulighed for at øve indflydelse på den hastighed, hvormed den successive oppumpning finder sted.For this device, connecting ducts equipped with a throttle valve are arranged between the sections. With the further developed apparatus, an attempt is made to achieve an automatic regulation of the successive inflation of the sections. Both of these cuffs have different drawbacks. The first apparatus because the manual operation of the control valves requires great practice on the part of the operator operating the apparatus and the further developed apparatus in that the throttle valves will ensure that the inflation takes place successively, but deprives the operator of the opportunity to influence the speed whereby the successive pumping takes place.

Den foreliggende opfindelse tager sigte på at afhjælpe disse ulemper. Ifølge opfindelsen er blodtømningsmanchetten ejendommelig ved det i den kendetegnende del af krav 1 angivne. Ved manchetten opnås det, at blodet i en legemsdel kan presses bort fra legemsdelen, efterhånden som sektionerne fyldes, og at blodet successivt presses væk, efter som sektionerne fyldes, efterhånden som den foregående sektion er fyldt og et forudbestemt tryk er opnået deri. Bortpresningen af blod kan således ske, uden at den oftest beskadigede kropsdel behøver at blive bevæget, og uden at der behøver at blive anvendt stor fysisk kraft. Endviderec·kan forløbet styres fuldstændigt ved betjening af manøvreorganet, idet fyldningen af den næste sektion først sker og kun i det omfang finder sted, hvor der kan tilvejebringes overskydende tryk i de foregående sektioner. Endvidere opnås der en sikkerhedsmargin, ved at sektionerne hurtigt kan tømmes, hvilket medfører, at blod hurtigt kan genindføres i legemsdelen, dersom det viser sig nødvendigt af operationstekniske eller andre medicinske årsager.The present invention aims to remedy these drawbacks. According to the invention, the blood emptying cuff is characterized by what is stated in the characterizing part of claim 1. At the cuff, it is achieved that the blood in a body part can be pressed away from the body part as the sections are filled, and that the blood is successively pressed away as the sections are filled, as the previous section is filled and a predetermined pressure is obtained therein. The squeezing out of blood can thus take place without the most often damaged body part having to be moved, and without the need to use great physical force. Furthermore, the course can be completely controlled by operating the actuator, the filling of the next section first taking place and only to the extent that excess pressure can be provided in the previous sections. Furthermore, a safety margin is achieved in that the sections can be emptied quickly, which means that blood can be quickly reintroduced into the body part if it proves necessary for surgical or other medical reasons.

Ifølge en hensigtsmæssig udformning er der mellem manøvreorganet og ventilerne forbundet en manøvreslange. Denne manøvreslange tilfører samtidig trykmedium til samtlige ventiler, og sikrer derved den hurtige tømning af manchetten for trykmedium.According to a suitable design, an operating hose is connected between the actuator and the valves. This control hose simultaneously supplies pressure medium to all valves, thereby ensuring the rapid emptying of the pressure medium sleeve.

Ifølge endnu en udførelsesform for opfindelsen omfatter ventilerne en fjederbelastet kugleventil, hvis åbningstryk er indrettet til at kunne varieres ved hjælp af en reguleringsanordning, idet ventilerne endvidere kan være forsynet med et trykstempel, som er indrettet til via et i manøvreslangen indført trykmedium at løfte kugleventilen til tømning af sektionerne.According to a further embodiment of the invention, the valves comprise a spring-loaded ball valve, the opening pressure of which is arranged to be able to be varied by means of a regulating device, the valves being further provided with a pressure piston which is arranged to lift the ball valve to a pressure medium inserted into the control hose. emptying of the sections.

Den. foreliggende opfindelse skal i det følgende beskrives nærmere under henvisning til tegningen, på hvilken fig. 1 viser en udførelsesform for blodtømningsmanchetten ifølge opfindelsen og fig. 2 viser en udførelsesform for en ventilindretning 3 141382 til blodtømningsmanchetten ifølge fig. 1.The. The present invention will be described in more detail below with reference to the drawing, in which fig. 1 shows an embodiment of the blood emptying cuff according to the invention and fig. 2 shows an embodiment of a valve device 3 for the blood emptying cuff according to fig. 1.

Et manøvreorgan 1 er ved hjælp af en påfyldningsslange 2 og en manøvreslange 3 sluttet til en manchet 8 bestående af et svagt tilspidset stykke formfast stof eller plastmateriale af blød, men ikke strækbar kvalitet. Manchettens hovedform er en afstumpet, ligebenet trekant, dvs. den har paralleltrapez-form, idet de to ikke parallelle sider er lige lange. Manchetten 8's to ikke parallelle sider 9a og 9b er forsynet med en delbar trækkæde 6, ved hjælp af hvilken manchetten kan formes til en svagt konisk cylinder. På den ene side af det formfaste materiale er der anordnet et antal sektioner 4, som er langstrakte og ligger placeret parallelt med paralleltrapezets parallelle sider. Sektionerne 4 er fremstillet af et strækbart, kraftigt plastmateriale, gummi eller andet lufttæt materiale. Sektionerne kan også bestå af balloner fastgjort i en lomme i manchetten.An actuator 1 is connected by means of a filling hose 2 and an actuating hose 3 to a cuff 8 consisting of a slightly tapered piece of form-retaining solid or plastic material of soft but not stretchable quality. The main shape of the cuff is a blunt, isosceles triangle, ie. it has a parallel trapezoidal shape, the two non-parallel sides being equal in length. The two non-parallel sides 9a and 9b of the sleeve 8 are provided with a divisible pull chain 6, by means of which the sleeve can be formed into a slightly conical cylinder. On one side of the form-retaining material, a number of sections 4 are arranged, which are elongate and lie parallel to the parallel sides of the parallel trapezoid. The sections 4 are made of a stretchable, strong plastic material, rubber or other airtight material. The sections may also consist of balloons attached to a pocket in the cuff.

Sektionerne 4 er endvidere seriekoblede ved hjælp af indbyrdes forbundne, specielle ventiler 5> som er indrettet til først at åbne, når et vist tryk opnås på ventilernes trykside.The sections 4 are furthermore connected in series by means of interconnected, special valves 5> which are arranged to open only when a certain pressure is obtained on the pressure side of the valves.

Til manchetten 8 hører der også det ovenfor nævnte manøvreorgan 1. Manøvreorganet indeholder en reduktionsventil, samt en omslagsventil 2o. Reduktionsventilen nedbringer et fra en ledning 7 indkommende lufttryk til 35o mm Hg. Fra manøvreorganet udgår påfyldnings slangen 2 og manøvreslangen 3, hvoraf den første er relativt groft kalibreret, medens den anden er forholdsvis fint kalibreret.The cuff 8 also includes the above-mentioned actuator 1. The actuator comprises a reduction valve, as well as a reversing valve 2o. The reduction valve reduces an air pressure coming in from a line 7 to 35o mm Hg. The filling hose 2 and the operating hose 3 emanate from the operating means, the first of which is relatively roughly calibrated, while the second is relatively finely calibrated.

Ventilerne 5 består af en kugleventil, hvor kuglen 12 kan trykkes mod seedet ved hjælp af en gennem en justeringsskrue 13 regulerbar kraft. Sektionerne 4's vægge er på fig. 2 markeret ved 4a og 4b, hvorved luft kan passere fra den nedre sektion i figuren via en åbning 18 og kugleventilen til den øvre sektion på figuren gennem en åbning 19 så snart lufttrykket overstiger det tryk, med hvilket kuglen belaster sit sæde.The valves 5 consist of a ball valve, where the ball 12 can be pressed against the seed by means of a force adjustable through an adjusting screw 13. The walls of the sections 4 are in fig. 2 marked at 4a and 4b, whereby air can pass from the lower section of the figure via an opening 18 and the ball valve to the upper section of the figure through an opening 19 as soon as the air pressure exceeds the pressure with which the ball loads its seat.

Ventilen 5 er endvidere forsynet med en særskilt manøvrecylinder lo, i hvilken et stempel 14 kan bevæge sig og ved hjælp af en stift 15 kan løfte kuglen fra dens sæde uanset lufttrykket i sektionerne. Til tilbageførsel af stemplet 14 til dets udgangsstilling er der endvidere monteret en returfjeder 16. I manøvrecylinderen lo udmunder der en kanal 17, som er forbundet med manøvreorganet l's manøvreslange 2.The valve 5 is further provided with a separate operating cylinder 10 in which a piston 14 can move and by means of a pin 15 can lift the ball from its seat regardless of the air pressure in the sections. To return the piston 14 to its initial position, a return spring 16 is further mounted. A channel 17 opens into the operating cylinder 10, which channel is connected to the operating hose 2 of the operating member 1.

141352 4 Når blodtømningsmanchetten 8 skal anvendes, lægges den under den ekstremitet, som skal tømmes, og lukkes rundt om denne ved hjælp af trækkæden 6. Manøvreorganet l's omslagsventil stilles på T (ifølge figuren), hvorved luft kan passere reduktionsventilen og påfyldningsslangen 2 til den første sektion, som derved fyldes med luft.When the blood emptying cuff 8 is to be used, it is placed under the extremity to be emptied and closed around it by means of the pull chain 6. The reversing valve 1 of the actuator 1 is set to T (according to the figure), whereby air can pass the reduction valve and the filling hose 2 to it. first section, which is thereby filled with air.

Når trykket i denne sektion har opnået den for kugleventilen indjusterede værdi, fortrinsvis 3oo mm Hg, løfter kuglen 12 sig og luften strømmer videre til næste sektion. Luften fylder på denne måde sektion efter sektion indtil hele manchetten er blevet fyldt med luft. Blodet drives derved i central retning, dvs. i retning mod hjertet. En sædvanlig trykmanchet anbringes derefter rundt om armen ovenfor blodtømningsmanchetten og pumpes op til passende tryk.When the pressure in this section has reached the value adjusted for the ball valve, preferably 30 mm Hg, the ball 12 lifts and the air flows on to the next section. In this way, the air fills section after section until the entire cuff has been filled with air. The blood is thereby driven in a central direction, ie. towards the heart. A conventional pressure cuff is then placed around the arm above the blood drain cuff and inflated to appropriate pressure.

Manøvreorganets omskifterventil stilles nu på F (ifølge figuren), hvorved påfyldningsslangen 2 sættes i forbindelse med yderluften samtidig med, at trykluften med trykket 35o mm Hg dirigeres til manøvreslangen 3 og via denne til alle ventilerne 5. Via kanalerne 17 og trykcylindrene 14 løftes nu kuglerne 12 fra disses sæder og luften kan strømme fra de øvre sektioner til de nedre sektioner og via påfyldningsslangen 2 ud i det frie. Blodtømningsmanchetten frigøres derefter, hvorefter operationen kan indledes.The switch valve of the actuator is now set to F (according to the figure), whereby the filling hose 2 is connected to the outside air at the same time as the compressed air with the pressure 35o mm Hg is directed to the actuator hose 3 and via this to all valves 5. Via the channels 17 and the pressure cylinders 14 the balls are now lifted 12 from their seats and the air can flow from the upper sections to the lower sections and via the filling hose 2 into the open air. The blood emptying cuff is then released, after which the operation can be started.

Under hele blodtømningsforløbet har ekstremiteten befundet sig i absolut stilhed og arbejdet er blevet udført af manchetten, hvorigennem besværligt fysisk arbejde, samt ikke mindst risikoen for komplikationer har kunnet elimineres.Throughout the bloodletting process, the extremity has been in absolute silence and the work has been done by the cuff, through which strenuous physical work, as well as not least the risk of complications has been eliminated.

Ovenfor er det vist, at ventilerne 5 forener sektionerne 4 ved at være placeret i sektionernes mellemvægge med en åbning i hver af sektionerne og på denne måde forener de sektionerne.Above, it is shown that the valves 5 join the sections 4 by being located in the partitions of the sections with an opening in each of the sections and in this way they join the sections.

Sektionerne kan også forenes ved hjælp af slanger, i hvilke ventilerne 5 monteres. Ventilerne 5 er vist åbne for tryk klar til tømning af sektionerne 4. Ventilerne kan dog også konstrueres således, at de holdes lukkede ved tømning ved hjælp af tryk, hvorved sektionerne tømmes, når trykket falder væk.The sections can also be joined by means of hoses in which the valves 5 are mounted. The valves 5 are shown open to pressure ready for emptying the sections 4. However, the valves can also be designed so that they are kept closed by emptying by means of pressure, whereby the sections are emptied when the pressure drops away.

Blodtømningsmanchetten kan også tænkes forsynet med andre typer ventiler end den ovenfor nævnte. I stedet for kugleventiler kan der anvendes ventiler med en membranstyret skyder, som idet trykket i den sektion, hvorudfor ventilen er placeret, når det forudbestemte niveau, forskyder skyderen således, at 141352 5 trykledningen sættes i forbindelse med den næstfølgende sektion samtidig med, at en åbning til det fri afbrydes. Herved vil de enkelte sektioner fyldes som ovenfor nævnt, medens sektionerne tømmes uden anvendelse af manøvreledning blot ved, at trykket til den første sektion falder væk.The blood emptying cuff may also be provided with other types of valves than the one mentioned above. Instead of ball valves, valves can be used with a diaphragm-controlled slider, which, as the pressure in the section outside which the valve is located reaches the predetermined level, displaces the slider so that the pressure line is connected to the next section at the same time as a opening to the open is interrupted. Hereby the individual sections will be filled as mentioned above, while the sections are emptied without the use of maneuvering line simply by the pressure to the first section falling away.
