Description
Foreliggende oppfinnelse vedrører et kateter for anvendelse ved submukos administrasjon av et lokalanestetisk middel for oppnåelse av paracervikal blokkering. The present invention relates to a catheter for use in the submucosal administration of a local anesthetic for achieving paracervical blockade.
Formålet med oppfinnelsen er å tilveiebringe et kateter som kan anvendes ved anestesisering av cervix, idet kateteret er beregnet for submukos anvendelse. The purpose of the invention is to provide a catheter that can be used for anesthetizing the cervix, the catheter being intended for submucosal use.
Det er tidligere kjent å injisere et anestetisk aktivt middel ved såkalt smerteløs overføring for oppnåelse av en paracervikal blokkering. Injeksjonen har derved blitt utført på en slik.måte at gynekologen ved hjelp av en hypodermisk sprøyte med en lang nål.injiserer et anestetisk middel subkutant og lateralt .på begge sider av cervix. Ulemper med denne metode er at injeksjonen må utføres flree ganger for å bibeholde den smerteløse tilstand. For.å.redusere antallet av injeksjoner brukes ofte en høy konsentrasjon og en stor dose av det anestetiske middel, men dette er imidlertid ikke ønskelig på grunn av det anestetisk aktive middels toksisitet. It is previously known to inject an anesthetic active agent by so-called painless transfer to achieve a paracervical block. The injection has therefore been carried out in such a way that the gynecologist, using a hypodermic syringe with a long needle, injects an anesthetic agent subcutaneously and laterally on both sides of the cervix. Disadvantages of this method are that the injection must be carried out several times to maintain the painless state. In order to reduce the number of injections, a high concentration and a large dose of the anesthetic agent is often used, but this is however not desirable due to the toxicity of the anesthetic active agent.
For å unngå denne ulempe har man benyttet en kateter-teknikk hvorved et kateter anbringes lateralt på hver side av cervix. Kateteret har en slik utforming at det ligger subkutant i vevet. De motsatte ender av kateteret med forbindelseselementer for tilknytning til en hypodermisk sprøyte er festet med klebe-båndpå pasientens lår. Når det er nødvendig kan små doser av To avoid this disadvantage, a catheter technique has been used whereby a catheter is placed laterally on each side of the cervix. The catheter has such a design that it lies subcutaneously in the tissue. The opposite ends of the catheter with connecting elements for connection to a hypodermic syringe are attached with adhesive tape to the patient's thigh. When necessary, small doses of
et anestetisk middel i lav konsentrasjon innføres gjennom katetrene. an anesthetic agent in low concentration is introduced through the catheters.
Det har imidlertid nå blitt vist at man oppnår en However, it has now been shown to achieve one
.smerteløs tilstand over et lengre tidsrom hvis det anestetisk aktive middel innføres submukost' i cervix.' Ved denne teknikk skal kateteret ligge bare J>-^ ™ dypt i motsetning til når subkutan anestesi oppnås hvorved kateteret ligger 10-15 mm dypt, hvilket betyr at kateteret for subkutan injeksjon ikke kan anvendes, men .painless condition over a longer period of time if the anesthetic active agent is introduced submucosally' into the cervix.' With this technique, the catheter should lie only J>-^ ™ deep, in contrast to when subcutaneous anesthesia is achieved whereby the catheter lies 10-15 mm deep, which means that the catheter for subcutaneous injection cannot be used, but
det er da nødvendig med et spesialkateter. a special catheter is then necessary.
Oppfinnelsen vedrører altså et kateter for submukøs applisering i livmorhalsen ved administrering av et lokalanestetisk virksomt stoff for oppnåelse av paracervikalblokkering, hvilket kateter omfatter en rørformet del som i sin for appli-. sering i livmorhalsen beregnede ende er forsynt med et bakoverrettet fra den rørformede del utskytende organ, idet kateteret er karakterisert ved at det bakoverrettede organ har form av en bakoverrettet med slisser forsynt krage 2, som omslutter kateterets 1 hele omkrets, hvorved avstanden fra kateterets fremre ende til kragen er slik at kateteret kan appliseres submukøst i cervix med kragen innleiret deri. The invention thus relates to a catheter for submucous application in the cervix by administering a local anesthetic active substance to achieve paracervical blockade, which catheter comprises a tubular part which in its application. sering in the cervix, the end is provided with an organ projecting backwards from the tubular part, the catheter being characterized in that the organ directed backwards has the form of a collar 2 directed backwards with slits, which encloses the entire circumference of the catheter 1, whereby the distance from the front end of the catheter to the collar is such that the catheter can be applied submucosally in the cervix with the collar embedded in it.
Ifølge en egnet utførelse er kragen delvis oppslisset. Ifølge en annen egnet utførelse danner kragen en vinkel According to a suitable embodiment, the collar is partially slit. According to another suitable embodiment, the collar forms an angle
på 30-45°C med kateterets lengdeakse. of 30-45°C with the catheter's longitudinal axis.
Uttrykket bakoverrettet krage betyr at det traktlignende rom som dannes mellom kragen og kateteret, har sin åpning mot den andre enden av kateteret hvilken ende ikke er forsynt med. krage. The term backward-directed collar means that the funnel-like space formed between the collar and the catheter has its opening towards the other end of the catheter which end is not provided with. collar.
Oppfinnelsen skal i det følgende beskrives mer detal-jert under henvisning til de vedlagte tegninger,, hvor figur 2 viser oppfinnelsen. In the following, the invention will be described in more detail with reference to the attached drawings, where Figure 2 shows the invention.
Det rørformede kateter 1 består av et•fleksibelt plast-materiale slik som polyeten, "Teflon R" eller lignende materiale egnet for engangsbruk. Kateteret 1, som er forsynt med en sentral uttaksåpning 4 i sin ene ende og en inritaksåpning ved sin andre ende,, er i nevnte første ende og umiddelbart tilstøtende til denne forsynt med en fastsittende krage 2 av samme materiale som kateteret. Kragen 2 har således en traktformet åpning mot den andre enden av kateteret som ikke er forsynt med noen krage. Kragen ifølge figur 1 er hel uten noen spalter eller slisser. Kragens ytre del 3 ligger omtrent 1-1,5 mm utenfor kateteret 1, når dette har en diameter på 1,5 mm, hvilket betyr at kragenes største diameter er 3,5-U,5 mm. Kragen 2 danner" videre en vinkel på 30-^5° med kateterets lengdeakse. , The tubular catheter 1 consists of a flexible plastic material such as polyethylene, "Teflon R" or similar material suitable for single use. The catheter 1, which is provided with a central outlet opening 4 at one end and an entry opening at the other end, is provided at said first end and immediately adjacent to it with a fixed collar 2 of the same material as the catheter. The collar 2 thus has a funnel-shaped opening towards the other end of the catheter which is not provided with a collar. The collar according to figure 1 is complete without any slits or slits. The collar's outer part 3 lies approximately 1-1.5 mm outside the catheter 1, when this has a diameter of 1.5 mm, which means that the collar's largest diameter is 3.5-U.5 mm. The collar 2 further forms an angle of 30-^5° with the longitudinal axis of the catheter.
Figur 2 viser kateteret ifølge'oppfinnelsen med en krage 2 som ligner den i figur 1. Denne kragen er. imidlertid forsynt med oppsliss-;inger 6 i et antall på minst 3, hensiktsmessig k-&, fortrinnsvis 5, idet slissenes 6 dybde er omkring halvparten av bredden på kragen 2. Slissene 6 på kragen 2 gjør at kragen lettere kan tilpasses til kateterets ytre overflate uten at det dermed de-formeres. Kragen 2 har ellers samme utseende som kragen i figur 1, dvs. at kragen danner samme vinkel med kateterets lengdeakse og har de samme dimensjoner. Figure 2 shows the catheter according to the invention with a collar 2 similar to that in Figure 1. This collar is. however, provided with slits 6 in a number of at least 3, suitably k-&, preferably 5, the depth of the slits 6 being about half the width of the collar 2. The slits 6 on the collar 2 mean that the collar can be more easily adapted to the outside of the catheter surface without it being deformed. Collar 2 otherwise has the same appearance as the collar in figure 1, i.e. that the collar forms the same angle with the longitudinal axis of the catheter and has the same dimensions.
Kateteret 1 innføres submukøst i den vaginale slim-hinne i fornix på begge sidene av cervix ved hjelp av et inn-føringsrør, også kalt Kobak's rør, som er oppslisset og hvori kateteret er anbragt, og en dor som er plassert inni kateteret og utformet med et oppkuttingssted ved hjelp av hvilket slimhinnen perforeres for innføring av kateteret. Røret og doren fjernes når kateteret er plassert i en dybde på 3-4 mm. Således anbringes et kateter på hver side av cervix og festes ved å trekkes litt bakover hvorved kragen foldes ut og kommer i inngrep med slimhinnen og holdes derved tilbake. De andre endene av katetrene festes i pasientens lår eller mave, og forsynes med forbindelsesdeler som leder til et injeksjonsapparat og således muliggjør en hyppig injeksjon av et lokalanestetisk aktivt middel i lave konsentrasjoner. Ved hjelp av den bakoverrettede krage 2 ligger kateteret godt fast i cervix under hele over-føringsperioden og fjernes først når overføringen er ferdig. Når kateteret fjernes ved å trekke det bakover, vrenges kragen og den bevi.rker derved ingen utvidelse av innføringshullet. På denne måten oppnås en hurtigere leging av slimhinnen. The catheter 1 is introduced submucosally into the vaginal mucosa in the fornix on both sides of the cervix using an introduction tube, also called Kobak's tube, which is slit and in which the catheter is placed, and a mandrel which is placed inside the catheter and designed with a cut site by means of which the mucosa is perforated for the introduction of the catheter. The tube and mandrel are removed when the catheter is placed at a depth of 3-4 mm. Thus, a catheter is placed on each side of the cervix and secured by pulling slightly backwards, whereby the collar unfolds and engages with the mucous membrane and is thereby held back. The other ends of the catheters are attached to the patient's thigh or abdomen, and are provided with connecting parts that lead to an injection device and thus enable frequent injection of a local anesthetic active agent in low concentrations. With the help of the backward-directed collar 2, the catheter is firmly fixed in the cervix during the entire transfer period and is only removed when the transfer is finished. When the catheter is removed by pulling it backwards, the collar is inverted and thereby causes no expansion of the insertion hole. In this way, faster healing of the mucous membrane is achieved.
Kateteret har i høy grad oppfylt de behov som opp-står ved tester utført med hensyn til bibeholdelse og innføring av et lokalanestetisk middel. The catheter has largely met the needs arising from tests carried out with regard to the retention and introduction of a local anesthetic agent.
