NAPRAVA ZA ATRAVMATSKO UVAJANJE SREDSTVA V CEVASTI ORGAN ŽIVEGA BITJADEVICE FOR ATRAUMATIC IMPLEMENTATION OF THE MEANS IN THE TUBE OF THE LIVING BODY

Predmet izumaThe subject of the invention

Predmet izuma je naprava za atravmatsko uvajanje sredstva, prednostno cevastega, fleksibilnega predmeta, kot je kateter, npr. kateter za umetno osemenjevanje, prenos zarodkov, sterilni odvzem in aplikacija vzorcev, v cevasti organ živega bitja.The object of the invention is a device for the atraumatic introduction of an agent, preferably a tubular, flexible object, such as a catheter, e.g. catheter for artificial insemination, embryo transfer, sterile collection and application of specimens into the tubular organ of a living being.

Tehnični problemA technical problem

Tehnični problem, ki ga rešuje izum, je zasnovati napravo, ki bo omogočila atravmatski dovod sredstva v obliki cevastega in fleksibilnega predmeta, prednostno katetra, npr. katetra pri postopku umetnega osemenjevanja, prenosa zarodkov, sterilnega odvzema in aplikacije vzorcev , na predhodno določeno in od vhodnega dela poljubno oddaljeno mesto v cevastem organu, prednostno rodila, in bo pri tem izključena možnost okužbe in/ali poškodbe notranjosti cevastega organa, pri čemer bo preko dovedenega cevastega sredstva mogoče na enostaven način in brez zapletov vnesti v notranjost cevastega organa poljubno aktivno sredstvo, npr. semensko tekočino minimalne količine pri postopku umetnega osemenjevanja ali instrument za opravljanje posegov v notranjosti cevastega organa.A technical problem solved by the invention is to design a device that will allow atraumatic delivery of the agent in the form of a tubular and flexible object, preferably a catheter, e.g. The catheter is preferably given birth in an artificial insemination, embryo transfer, sterile collection and application of samples at a predetermined and inlet location in a tubular organ, excluding the possibility of infection and / or damage to the inside of the tubular organ, via the tubular means supplied, any active agent can be easily and easily inserted into the interior of the tubular organ, e.g. the seminal fluid of a minimal amount in the artificial insemination procedure or the instrument for performing interventions inside the tubular organ.

Stanje tehnikeThe state of the art

Za vstopanje v cevaste organe z namenom diagnosticiranja in zdravljenja kot tudi oplojevanja se pogosto uporabljajo katetri ustreznih zasnov. Pri postopku oploditve se s pomočjo katetra seme prenese globoko v rodila. S tem se prepreči velika izguba semena na poti skozi začetne dele rodil. Pri takem postopku se skozi kateter večjega premera uvede in nato potiska naprej globlje v rodila gibljivi tanjši kateter. Pri tem lahko pride do poškodb sluznice ali celo predrtja stene maternice. Zaradi potiskanja katetra od začetnih delov rodil v notranjost obstaja tudi velika nevarnost vnosa infekta v globlje dele rodil. V izogib slabostim opisanega postopka so bile podane številneCatheters of appropriate designs are often used to enter the tubular organs for diagnosis and treatment as well as fertilization. During the fertilization procedure, the catheter is transported deep into the childbirth through the catheter. This prevents a large loss of semen on the way through the initial parts of the birth. In such a procedure a larger, smaller catheter is introduced through a larger diameter catheter and then pushed deeper into the birth. This can damage the mucous membrane or even pierce the uterine wall. Due to the pushing of the catheter from the initial parts of the womb into the interior, there is also a high risk of introducing the infection into the deeper parts of the womb. In order to avoid the disadvantages of the described procedure, many have been given

35627_Prijava.doc/08 rešitve. Tako je v US 6,526,917 opisana naprava za vnos sredstva v obliki membrane, s pomočjo katere se pri postopku oplojevanja dovede seme v notranjost rodil. Naprava sestoji iz trše zunanje cevi in v cevi vstavljene, po premeru zožujoče gibke membrane. Membrana je s širšim koncem pritijena na koncu trde cevi, ki se vstavi v organ, drugi konec ima zožen v koničast vrh. Na nasprotnem, zunanjem koncu trde cevi se nahaja stisljivi vsebnik ali brizga zadostnega volumna. Vsebnik vsebuje tekočino s semenom. S potiskanjem tekočine s semenom v trdo cev se v cevi ustvaija tlak, ki povzroči izvijanje gibke membrane ven iz trde cevi v notranjost organa. Ko se celotna membrana izvije iz trde cevi, se vrh membrane zaradi tlaka razpre in razredčeno seme izteče v notranjost rodil. Opisana naprava ima v primeijavi s klasičnim katetrom vrsto prednosti, predvsem zmanjšuje možnost nastanka poškodb sluznice in stene organov, zmanjša možnost vnosa infekta v notranjost rodilnih organov in omogoča apliciranje semena globoko v rodila.35627_Login.doc / 08 solutions. Thus, U.S. Pat. No. 6,526,917 describes a device for introducing a membrane-shaped agent by which seed is brought into the plant during the fertilization process. The device consists of a stiffer outer tube and a narrowing flexible membrane diametrically inserted into the tube. The diaphragm is attached to the end with a wider end at the end of the rigid tube, which is inserted into the organ, the other end having a tapered tip. On the other hand, there is a compressible container or a syringe of sufficient volume on the outer end of the hard tube. The container contains liquid with semen. By pushing the seed fluid into the hard tube, pressure is created in the tube, which causes the flexible membrane to protrude from the hard tube inside the organ. When the entire membrane is unscrewed from the hard tube, the top of the membrane opens due to pressure and the diluted seed drains into the inside of the root. The described device has a number of advantages in comparison with a classical catheter, in particular it reduces the possibility of damage to the mucous membranes and the wall of the organs, reduces the possibility of introducing the infection into the interior of the fertile organs and enables the application of semen deep into the genera.

Za vzpostavitev zadostnega tlaka v cevi oz. membrani, ki povzroča izvijanje membrane iz trde cevi, je potrebna dovolj velika količina tekočine. Ker običajno ni na voljo tako velike količine semena, se seme meša s tekočino in se kot zelo razredčeno vnaša v rodila. Vnos močno razredčenega semena namesto koncentriranega semena ima zelo negativen vpliv na uspeh oploditve. Dodatne izgube semena in s tem negativni vpliv na oploditev predstavlja tudi velik volumen in s tem notranje stene naprave, na katere se naleplja aktivno seme. Ko se membrana razpre, se v notranjost organa poleg semena razlije tudi tekočina. Zaradi potrebe po večji količini tekočine se poveča možnost vnosa infekta v notranjost organa. Kot sredstvo za ustvaijanje tlaka se lahko uporabi tudi zrak, ki tudi predstavlja potencialni vir okužbe.To establish sufficient pressure in the pipe or tube. a membrane that causes the membrane to bend out of the hard tube requires a sufficient amount of fluid. Since such a large amount of seed is not usually available, the seed mixes with the liquid and is very diluted into the root. The intake of heavily diluted seed instead of concentrated seed has a very negative effect on the success of fertilization. The additional seed loss and thus the negative impact on fertilization is also the large volume and thus the internal walls of the plant to which the active seed is attached. When the membrane is opened, liquid is spilled into the organ in addition to the semen. Due to the need for more fluid, the possibility of introducing the infection inside the organ increases. Air can also be used as a pressure reliever, which also represents a potential source of infection.

Ker tekočina oz. zrak vstopa v trdo cev v osni smeri cevi, deluje največji tlak na vrh membrane in lahko povzroči njeno gubanje namesto izvijanje iz cevi. V takem primeru pride do zagozditve membrane v trdi cevi in postopka oploditve ni mogoče izvesti.Because the fluid or. air enters the rigid tube in the axial direction of the tube, exerts maximum pressure on the top of the diaphragm and can cause it to wrinkle rather than bend out of the tube. In this case, the membrane gets stuck in the hard tube and the fertilization process cannot be performed.

V primeru, ko se opisano napravo uporablja v druge namene, npr. diagnostične, se po izvitju membrane odstrani tekočino ali s predrtjem membrane, da tekočina iztečeIn case the described device is used for other purposes, e.g. diagnostic, the fluid is removed after the membrane is bent or the membrane is punctured to allow the fluid to flow out

35627_Prijava.doc/08 v organ ali s sesanjem tekočine ven iz membrane. V prvem primeru je organ napolnjen s tekočino, ki lahko ovira preiskave, v drugem primeru se stene izpraznjene membrane nagubajo in stisnejo in s tem otežijo ali celo preprečijo prehodnost instrumentu. Lahko pride tudi do predrtja stene membrane ali celo stene notranjega organa.35627_Application.doc / 08 to the organ or by sucking fluid out of the membrane. In the first case, the organ is filled with fluid that may interfere with the tests, in the second case the walls of the emptied membrane will sag and squeeze, making it difficult or even preventing the passage of the instrument. Penetration of the membrane wall or even the wall of the internal organ can also occur.

Rešitev tehničnega problemaThe solution to a technical problem

Opisani tehnični problem je rešen z napravo po izumu, izvedene iz trde cevi, zaprte na enem koncu, v trdi cevi vstavljene cevaste, fleksibilne membrane, ki je z enim koncem pritajena na koncu trde cevi, ki se vstavi v organ, in enote za ustvaijanje tlaka v trdi cevi, katere bistvena značilnost je v tem, da vsebuje fleksibilno cev, katere en konec je povezan s koncem membrane, nahajajočim v notranjosti trde cevi, tako da prebada membrano in štrli v njeno notranjost, drugi konec sega ven iz trde cevi in je tesno zaprt. Dolžina fleksibilne cevi je enaka ali večja od dolžine membrane. Enota za tlak poljubne znane vrste, npr. brizga, črpalka, ki s pomočjo tekočine v trdi cevi ustvaija tlak, je razporejena na poljubnem mestu ob napravi. Tlačna enota je preko cevke povezana s trdo cevjo na koncu trde cevi, ki se vstavi v organ, tako da tekočina, ki priteka v prostor med steno trde cevi in membrano, ustvaija največji tlak neposredno na mestu zvijanja membrane iz trde cevi.The technical problem described is solved by a device according to the invention, made of a hard tube closed at one end, a tubular, flexible membrane inserted into the hard tube at one end at the end of a hard tube inserted into the organ, and a mouthpiece pressure in the hard tube, the essential feature of which is that it contains a flexible tube, one end of which is connected to the end of the diaphragm located inside the hard tube so that it pierces the membrane and protrudes into it, the other end extends out of the hard tube, and it is tightly closed. The length of the flexible tube is equal to or greater than the length of the diaphragm. Pressure unit of any known type, e.g. syringe, a pump that generates pressure by means of a fluid in a hard tube, is arranged at any location next to the device. The pressure unit is connected via a tube to a hard tube at the end of the hard tube, which is inserted into the organ, so that the fluid flowing into the space between the wall of the hard tube and the membrane produces the maximum pressure directly at the point of twisting of the membrane from the hard tube.

Cevasta membrana se zaradi povišanega tlaka, ki je posledica uvajanja tekočine v trdo cev, izvija iz trde cevi v notranjost cevastega organa in z drugim, notranjim koncem vleče fleksibilno gibko cev. Ko je celotna membrana izvita iz trde cevi, se prosti štrleči konec fleksibilne cevke, ki je prednostno izvedena kot kateter, nahaja na predhodno določenem mestu znotraj cevastega organa. Skozi fleksibilno cevko se v notranjost organa aplicira želeno snov, npr. seme, zarodke, zdravilo idr. V primeru diagnosticiranja ali zdravljenja se za fleksibilno cevko uporabi dovolj velik kateter, ki omogoča prehod instrumentu znane vrste oz. se na konec membrane namesto fleksibilne cevke pritrdi začetni del instrumenta. Tekočina, ki ustvaija tlak v trdi cevi, ostaja v notranjosti trde cevi in membrane in ne pride v stik z notranjim organom. KoDue to the increased pressure resulting from the introduction of the fluid into the rigid tube, the tubular membrane curves out of the rigid tube into the interior of the tubular organ and pulls the flexible flexible tube with the other, inner end. When the entire membrane is protruded from the hard tube, the free projecting end of the flexible tube, preferably a catheter, is located at a predetermined location within the tubular organ. Through the flexible tube, the desired substance is applied to the interior of the organ, e.g. semen, embryos, medicine, etc. In the case of diagnosis or treatment, a sufficiently large catheter is used for the flexible tube to allow passage of an instrument of a known type or. an initial part of the instrument is attached to the end of the diaphragm instead of a flexible tube. The fluid that creates pressure in the hard tube stays inside the hard tube and membrane and does not come into contact with the internal organ. Who

35627_Prijava.doc/08 je postopek končan, se tekočina izčrpa iz trde cevi in membrane nazaj v tlačno enoto, fleksibilna cevka se izvleče, z njo pa tudi membrana.35627_Log in.doc / 08 the process is completed, the fluid is pumped out of the hard tube and membrane back into the pressure unit, the flexible tube is pulled out, and with it the membrane.

Tako zasnovana naprava ima številne prednosti. Naprava zaradi fleksibilne cevke omogoča apliciranje minimalne količine snovi na predhodno določeno mesto. Fleksibilna cevka ima gladke notranje stene s čimer se zelo zmanjša nalepljanje aktivne substance. Zaradi majhnega volumna fleksibilne cevke, za uspešen poseg zadostuje minimalna količina substance, zato ni potrebe po dodatni, nosilni tekočini. Aplicirana substanca ima sestavo, kot jo zahteva postopek, zato so rezultati postopkov, npr. oploditve bistveno izboljšani. Mesto apliciranja se določi s pomočjo dolžine membrane. Izvitje membrane iz trde cevi se med samim postopkom uvajanja sredstva v organ enostavno in neprestano nadzira s pomočjo dolžine še ne vstavljene fleksibilne cevke.A device designed in this way has many advantages. Due to the flexible tube, the device allows the application of a minimal amount of the substance to a predetermined location. The flexible tube has smooth inner walls, which greatly reduces the adhesion of the active substance. Due to the small volume of the flexible tube, a minimal amount of substance is sufficient for successful intervention, so there is no need for additional carrier fluid. The substance administered has the composition as required by the process, so the results of the processes, e.g. fertilization significantly improved. The site of application is determined by the length of the membrane. The bending of the hard tube membrane is easily and continuously monitored by the length of the flexible tube not yet inserted during the process of introducing the agent into the organ.

Naprava po izumu zagotavlja v bistvu popolno aseptično vstavitev sredstva na poljubno oddaljen del v notranjosti cevastega organa, ker pri napredovanju v notranjost organa membrana ne napreduje po principu porivanja pač pa na steno organa nalega vedno nov in infektov prost del membrane. Prosti konec uvajalnega sredstva, skozi katerega se aplicira npr. seme, je ves čas potovanja skozi organ zaščiten z membrano in pride v stik z notranjostjo organa šele na za to določenem mestu.The device according to the invention provides essentially aseptic insertion of the agent to an arbitrarily distant part inside the tubular organ, since as it advances into the organ, the membrane does not progress on the principle of bursting, but a new and infectious free part of the membrane rests on the wall of the organ. The free end of the introducing agent through which it is administered e.g. the semen is protected by a membrane throughout its journey through the organ and does not come into contact with the organ's interior only at a designated place.

Ker tekočina, s pomočjo katere se ustvaija tlak za izvijanje membrane, v času celotnega delovanja naprave nikoli ne pride v stik s katerim koli delom notranjega organa, je možnost vnosa infekta v notranjost organa popolnoma preprečena.As the fluid by which pressure is generated to bend the membrane never comes into contact with any part of the internal organ during the entire operation of the device, the possibility of introducing the infection inside the organ is completely prevented.

Možnost zapletov pri izvajanju postopka uvajanja sredstva v cevast organ je minimalna. Zaradi dovajanja tekočine v trdo cev neposredno na mesto izvijanja membrane, ne more priti do nagubanja membrane in zagozdenja le te znotraj trde cevi.The possibility of complications in carrying out the process of introducing an agent into a tubular organ is minimal. Due to the fluid being injected directly into the rigid tube at the point of diaphragm bending, it cannot cause the membrane to bend and get stuck inside the rigid tube.

Membrana je ves čas postopka, od začetka izvijanja do zaključka izvedbe določenega postopka, razšiijena na svoj največji premer. S tem je preprečeno kakršnokoli nagubanje sten membrane ali stisnjenje sten, ki bi lahko privedlo do predrtja in poškodbe notranje stene organa.The membrane is expanded to its maximum diameter throughout the process, from the beginning of the winding to the completion of a particular procedure. This prevents any wrinkling of the walls of the membrane or compression of the walls, which could lead to puncture and damage to the internal wall of the organ.

Drugi konec 11 trde cevi 1 je tesno zaprt s čepom 12 in se med postopkom nahaja izven organa. V notranjosti trde cevi 1 se nahaja fleksibilna cev 3, ki je z enim svojim koncem 6 povezana z notranjim koncem 8 membrane 2, tako da prebada membrano 2 in štrli v njeno notranjost, drugi konec 7 fleksibilne cevi 3 sega skozi odprtino 14 čepa 12 ven iz trde cevi 1. Vez fleksibilna cev 3 / membrana 2 je izvedena na za zrak tesen način. Odprtina 14 je tako zasnovana, da fleksibilna cev 3 med uvajanjem v organ neovirano potuje hkrati pa preprečuje iztekanje tekočine z ustrezno viskoznostjo. V bistvu celotna fleksibilna cev 3 se na začetku uvajanja v cevast organ razprostira izven trde cevi 1. Konec 7 fleksibilne cevi 3 služi za namestitev poljubne priprave za vnosA device for the atraumatic introduction of an agent, preferably a tubular, flexible object such as a catheter, into the tubular organ of a living being is made of a rigid tube 1 in which a flexible tubular membrane is arranged 2. The membrane 2 is provided with one end 9 with a retaining ring 13 to tight mode secured at the end 10 of the hard tube 1 inserted into the organ 1. The opposite end 8 of the membrane 2 is located inside the hard tube 1. The other end 11 of the hard tube 1 is closed tightly with the plug 12 and is located outside the body during the process. Inside the hard tube 1 there is a flexible tube 3 which with one end 6 is connected to the inner end 8 of the membrane 2 by piercing the membrane 2 and projecting into its interior, the other end 7 of the flexible tube 3 extends through the opening 14 of the plug 12 out made of hard tube 1. The flexible tube 3 / diaphragm 2 is made in an air tight manner.

In such a case, air may be used as the pressure-reducing agent. In this case, the bending of the membrane 2 and the advancement of the flexible tube 3 are controlled by ultrasound.

Tlačna enota 5 poljubne znane vrste, npr. brizga, črpalka, ki s pomočjo tekočine v trdi cevi 1 ustvarja tlak, je razporejena na poljubnem mestu ob napravi. Tlačna enota 5 je s trdo cevjo 1 povezana preko cevke 4, ki v trdo cev 1 vstopa na koncu 10, ki je vstavljen v organ, trde cevi 1, tako da tekočina, ki priteka v prostor med steno trde cevi 1 in membrano 2, ustvaija največji tlak neposredno na mestu izvijanja membrane 2 iz trde cevi 1.Pressure unit 5 of any known type, e.g. syringe, a pump which, by means of a fluid in a hard tube 1, generates pressure, is disposed at any place adjacent to the apparatus. The pressure unit 5 is connected to the hard tube 1 via a tube 4 which enters the hard tube 1 at the end 10, which is inserted into the body, of the hard tube 1 so that the fluid flowing into the space between the wall of the hard tube 1 and the membrane 2, it produces maximum pressure directly at the point of divergence of the membrane 2 from the hard tube 1.

Premer, dolžina in oblika membrane 2 je odvisna od vrste postopka, ki se ga izvaja in od vrste cevastega organa. Dolžina fleksibilne cevi 3 je odvisna od dolžine membrane 2, pri čemer je dolžina fleksibilne cevi 3 enaka ali večja od dolžine membrane 2. V primeru, če je cevasti organ notranje razvejan, se z ustreznim oblikovanjem membrane 2 določi pot uvajanja.The diameter, length and shape of the membrane 2 depend on the type of process being performed and the type of tubular organ. The length of the flexible tube 3 depends on the length of the membrane 2, wherein the length of the flexible tube 3 is equal to or greater than the length of the membrane 2. If the tubular organ is branched internally, the route of introduction is determined by appropriate design of the membrane 2.

Vsakokratni sestavni deli naprave so izdelani iz materialov ustreznih mehanskih lastnosti, ki omogočajo vsakokratnemu delu, da izvaja svojo funkcijo. Razumljivo je, da morajo biti materiali neškodljivi za bitja podvržena postopkom in hkrati kemično odporna na snovi v telesu bitja.Each component of the device is made of materials of appropriate mechanical properties that allow each part to perform its function. It is understood that materials that are harmless to creatures must undergo processes and at the same time be chemically resistant to substances in the creature's body.

Napravo je mogoče zasnovati tako, da je večkratno uporabljiva, pri čemer membrana 2 skupaj s fleksibilno cevko 3 tvori izmenljivi del naprave, ki se ga namesti v trdo cev 1 in ustrezno zatesni s čepom 12 oz. tesnilnim obročem 13.The device can be designed to be reusable, with the diaphragm 2 together with the flexible tube 3 forming a removable part of the device, which is mounted in a hard tube 1 and sealed accordingly with a pin 12 or. sealing ring 13.

Razumljivo je, da lahko strokovnjak s tega področja na osnovi poznavanja opisa izuma izvede tudi drugačne posamezne izvedbene spremembe, ne da bi obšel bistvo izuma, kot je opredeljeno v sledečih patentnih zahtevkih.It is understandable that one skilled in the art may, on the basis of knowledge of the description of the invention, also make different individual implementation changes without circumventing the essence of the invention as defined in the following claims.
