Description
Aspirasjons- og infusjonsnål. Aspiration and infusion needle.
Oppfinnelsen angår en forbedret aspirasjons- og infusjonsnål som spesielt, men ikke utelukkende, er beregnet for bruk på dét kliniske område. The invention relates to an improved aspiration and infusion needle which is particularly, but not exclusively, intended for use in the clinical area.
Det er kjent innen medisinen at det ofte er nødvendigIt is known in medicine that it is often necessary
å trekke oppløsninger fra små beholdere eller flasker som er for-seglet ved hjelp av korker eller propper av gummi eller lignende materiale, ved bruk av en aspirasjonsnål som føres gjennom korken inn i beholderens eller flaskens indre del. •Den spisse ende på slike nåler har imidlertid en slik form at splinter av elastomerisk materiale ofte avskjæres fra.prop-pen og delvis eller fullstendig sperrer aspirasjonskanalen i nålen, to withdraw solutions from small containers or bottles that are sealed by means of corks or stoppers of rubber or similar material, using an aspiration needle which is passed through the cork into the inner part of the container or bottle. •The pointed end of such needles, however, has such a shape that splinters of elastomeric material are often cut off from the prop and partially or completely block the aspiration channel in the needle,
og således hindrer eller forsinker oppsugingen av oppløsningen som følgelig utsettes for forurensning. Dersom.den samme nål som brukes for oppsuging av oppløsningen deretter anvendes for.injeksjon av oppløsningen, foreligger den risiko at splinter av det elastomeriske materiale som kan foreligge i nålkanalen, injiseres sammen med opp-løsningen. and thus prevents or delays the absorption of the solution which is consequently exposed to contamination. If the same needle that is used for aspiration of the solution is then used for injection of the solution, there is a risk that splinters of the elastomeric material that may be present in the needle channel are injected together with the solution.
Det er således et formål ved foreliggende oppfinnele. å tilveiebringe en forbedret aspirasjons- og infusjonsnål med en form slik at splinter ikke dannes når nålen trenger gjennom elastomerisk materiale. It is thus an object of the present invention. to provide an improved aspiration and infusion needle with a shape such that splinters do not form when the needle penetrates elastomeric material.
Ifølge oppfinnelsen er tilveiebragt en nål for bruk ved aspirasjon (oppsuging) og infusjon (innføring).av oppløsninger,'om-fattende et stort sett sylindrisk legeme som i sin ene ende avsmalner til en spiss og som omfatter en stort sett aksialt gjennom-løpende boring som avviker fra aksialretningen i området ved spiss- According to the invention, a needle is provided for use during aspiration (suction) and infusion (introduction) of solutions, comprising a largely cylindrical body which tapers to a point at one end and which comprises a largely axially continuous drilling that deviates from the axial direction in the area at the tip
en og munner ut i en sideflate på legemet, og hvor krumningen på legemets overflate motsatt nevnte sideflate er slik at legiemet ved spissen trekker seg over den stort sett aksialt rettede.del av den gjennomløpende boring. one and opens into a side surface of the body, and where the curvature of the surface of the body opposite said side surface is such that the body at the tip pulls over the largely axially aligned part of the continuous bore.
For at oppfinnelsen lettere skal forstås skal/TjdetIn order for the invention to be more easily understood shall/Tjdet
følgende et utføringseksempel av denne beskrives nærmere under hen-visning til vedlagte tegning hvor: Figur 1 er et lengdesnitt av den forbedrede nål ifølge . foreliggende oppfinnelse, og In the following, an embodiment of this is described in more detail with reference to the attached drawing where: Figure 1 is a longitudinal section of the improved needle according to . present invention, and
figur 2 er'et oppriss av nålen ifølge oppfinnelsen,figure 2 is an elevation of the needle according to the invention,
dreiet 90° i forhold til aksen II-II i figur 1.rotated 90° in relation to axis II-II in Figure 1.
På tegningen.omfatter nålen 1 et vesentlig sylindrisk legeme 2, en aksial boring 3, et skråparti 5, og en. bueformet eller krum spiss 8. In the drawing, the needle 1 comprises a substantially cylindrical body 2, an axial bore 3, an inclined portion 5, and a. arched or curved tip 8.
Spissen 8 på nålen 1 er krum ved dens endevegg 4 slik at boringen 3 minste tverrsnittsareal ved spissen 8 danner en vinkel med én akse vinkelrett på aksen II-II. Spesielt ligger erideseksjonen 6 til boringen 3 i nålen l i et plan stort sett parallelt med aks,' en -~' II-II.. Følgelig vil gjénnomtrengning av nålen 1, for-eksempel gjennom artikler av elastomerisk materiale egnet for. tettende lukking av beholdere og små flasker inneholdende oppløsninger, medføre av-skjæring av trevler eller spon av dette materiale og innføring av' The tip 8 of the needle 1 is curved at its end wall 4 so that the smallest cross-sectional area of the bore 3 at the tip 8 forms an angle with one axis perpendicular to the axis II-II. In particular, the eride section 6 of the bore 3 in the needle 1 lies in a plane largely parallel to the axis,' a -~' II-II. Consequently, penetration of the needle 1, for example through articles of elastomeric material will be suitable for. sealing of containers and small bottles containing solutions, resulting in the cutting off of fibers or chips of this material and the introduction of
slike spon i nålens gjennomløpende boring, etter som boringens 3 tverrsnittsareal som støter mot forseglingen er 0 ved gjénnomtrengning such chips in the continuous bore of the needle, after which the cross-sectional area of the bore 3 that abuts the seal is 0 in case of penetration
av en plan overflate vinkelrett på aksen II-II i figur 1. of a flat surface perpendicular to the axis II-II in figure 1.
Skråpartiet 5 utgjøres av en fordypning i veggen nær endeseksjonen .6. Skråpartiet 5 muliggjør sliping 'av spissen 7. The slanted part 5 consists of a recess in the wall near the end section .6. The slanted portion 5 enables grinding of the tip 7.
