1DK 2009 00048 U3 Nålekanyle med et blokeringselement samt nål til veterinær brug, hvortil den anvendes1GB 2009 00048 U3 Needle needle with a blocking element and a needle for veterinary use, to which it is used
Teknisk områdeTechnical area
Den foreliggende opfindelse angår generelt en nål og en nålekanyle, især en nål og en nålekanyle til veterinær brug.The present invention generally relates to a needle and a needle cannula, in particular a needle and a needle cannula for veterinary use.
BaggrundBackground
Med forbedringerne i levevilkårene er antallet af husdyr på husdyrbedrifterne blevet stadigt større og større, hvilket fører til en stigning i det antal af injektioner til vaccinering og behandling af husdyrene, der udføres af dyrlægerne eller husdyrholderne. Imidlertid medfører injektionen smerter på husdyret, og det vil bevæge sig så voldsomt, at kanylens ståldel knækker over, og den afbrækkede del efterlades i dyrets krop. Idet den forreste ende af nålekanylen er skarp vil den afbrækkede nål bevæge sig direkte ind i kroppen, når dyret udfører voldsomme bevægelser. Dette gør først ondt på dyret, og derefter vil den afbrækkede nål, der forbliver i kroppen, sandsynligvis forårsage skade på en person, når kroppen omdannes til viderebehandlede fødevarer i et slagteri, fordi den afbrækkede nål ikke er nem at finde, når den forbliver i kødet.With the improvements in living conditions, the number of livestock on the livestock farms has been steadily increasing, leading to an increase in the number of injections for vaccination and treatment of the livestock performed by the veterinarians or livestock keepers. However, the injection causes pain to the animal and it will move so violently that the steel part of the cannula breaks over and the broken part is left in the animal's body. As the front end of the needle cannula is sharp, the broken needle will move directly into the body as the animal performs violent movements. This first hurts the animal, and then the broken needle that remains in the body is likely to cause harm to a person when the body is transformed into processed foods in a slaughterhouse because the broken needle is not easy to find when left in the meat.
For i tide at finde den afbrækkede nål, som er forblevet i dyret, vil mange slagterier eller the Foodstuffs Inspection Center undersøge slagtedyret under anvendelse af en metaldetektor. Men de nålekanyler, der anvendes til traditionelle nåle til veterinær brug, er lavet af grad 304 rustfrit stål, som kan være vanskelig at detektere med metaldetektorerne.In time to find the broken needle that remained in the animal, many slaughterhouses or the Foodstuffs Inspection Center will investigate the slaughter animal using a metal detector. However, the needle needles used for traditional veterinary needles are made of grade 304 stainless steel, which can be difficult to detect with the metal detectors.
For at håndtere dette har adskillige US patenter, såsom US 6.599,276 og US 6.488.668, fokus på de løsninger, der vedrører valg og forbedringer af de materialer, der anvendes til at fremstille nålekanylerne.To address this, several US patents, such as US 6,599,276 and US 6,488,668, focus on the solutions pertaining to the selection and improvement of the materials used to manufacture the needle needles.
Disse løsninger er begrænset til materialerne til nålekanylerne og er beregnet på at øge muligheden for at detektere de afbrækkede nåle inden i kødet af 2 2DK 2009 00048 U3 dyrene, Det vil sige, at ingen af disse løsninger er i stand til at forhindre de afbrækkede nåle i at bevæge sig ind i kroppene.These solutions are limited to the needle cannula materials and are intended to increase the ability to detect the broken needles within the flesh of the 2 2DK 2009 00048 U3 animals, that is, none of these solutions are capable of preventing the broken needles in moving into the bodies.
Kort beskrivelse af frembringelsenBrief description of the production
Der beskrives ifølge nærværende frembringelse en nålekanyle med et bloke-ringselement og en nål til veterinær brug, hvortil kanylen anvendes og som er beregnet til at løse et problem, der består i, at de kendte nålekanyler til veterinær brug bevæger sig ind i dyrenes kød, efter at de er knækkede.According to the present invention, there is disclosed a needle cannula having a blocking element and a needle for veterinary use to which the cannula is used and which is intended to solve a problem which consists in the prior art needle needles moving into the animal's flesh, after they are cracked.
Med den foreliggende frembringelse tilvejebringes der en nålekanyle, som har en skarp ende, en bundende og et rørformet element med en væg og en kavitet, som strækker sig mellem den skarpe spids og bundenden, hvor i det mindste et blokeringselement, der er tilvejebragt på væggen af nålekanylen, rager ud fra væggen af nålekanylen.With the present invention there is provided a needle cannula having a sharp end, a bottom and a tubular element having a wall and a cavity extending between the sharp tip and the bottom end, wherein at least one blocking element provided on the wall of the needle cannula, protruding from the wall of the needle cannula.
Med den foreliggende frembringelse tilvejebringes endvidere en nål til veterinær brug, som omfatter en nåleholder og en nålekanyle med en skarp ende, en bundende og et rørformet element med en væg og en kavitet, som strækker sig mellem den skarpe spids og bundenden, hvor i det mindste et blokeringselement, der er tilvejebragt på væggen af nålekanylen, rager ud fra væggen af nålekanylen.The present invention further provides a veterinary needle comprising a needle holder and a needle end having a sharp end, a bottom and a tubular member having a wall and a cavity extending between the sharp tip and the bottom end where at least one blocking element provided on the wall of the needle cannula protrudes from the wall of the needle cannula.
Den nål og nålekanyle til veterinær brug, der tilvejebringes med den foreliggende frembringelse, forhindrer den afbrækkede nål i at anbringe sig helt inde i injektionsstedet, efter at den er brækket af, fordi blokeringselementet på væggen af nålekanylen kan holde den afbrækkede nål ude af dyrets krop, hvilket gør det nemmere ikke blot at udtage den afbrækkede nål og dermed lindre dyrets lidelser, men også at reducere den arbejdsbelastning, som påhviler slagteriet og Foodstuffs Inspection Center.The veterinary needle and needle needle provided with the present invention prevents the aborted needle from inserting fully into the injection site after being broken off, because the blocking element on the wall of the needle cannula may keep the broken needle out of the animal's body. which makes it easier not only to remove the broken needle and thus relieve the animal's suffering, but also to reduce the workload of the slaughterhouse and the Foodstuffs Inspection Center.

Foretrukne udførelsesformer for frembringelsenPreferred embodiments of the invention
Som vist på fig. 1 omfatter en traditionel nål 100 til veterinær brug en nålekanyle 10 og en nåleholder 20. Kanylen 10 har en bundende 12 og en skarp ende 14, som er beregnet til at komme i kontakt med injektionsstederne.As shown in FIG. 1, a conventional needle 100 for veterinary use includes a needle cannula 10 and a needle holder 20. The cannula 10 has a bottom 12 and a sharp end 14 which are intended to contact the injection sites.
En skarp spids 102 strækker sig fra den skarpe ende 14 og til bundenden 12, som stikkes ind i et forventet injektionssted, når der foretages injektioner i dyrene. En samling 106 strækker sig fra bundenden 12 og til den skarpe ende 14, som er fastgjort i en nåleholder 20, når nålekanylen og nåleholderen forbindes, så de udgør en nål. Og mellem samlingen 106 og den skarpe spids 102 strækker der sig en eksponeret del 104. Generelt er nålekanylen og nåleholderen nittet fast på lokalitet A til dannelse af en nåleenhed.A sharp tip 102 extends from the sharp end 14 to the bottom end 12 which is inserted into an expected injection site when injections are made in the animals. A joint 106 extends from the bottom end 12 and to the sharp end 14 which is secured in a needle holder 20 when the needle cannula and needle holder are connected to form a needle. And between the joint 106 and the sharp tip 102 extends an exposed portion 104. In general, the needle cannula and needle holder are riveted to location A to form a needle unit.
I praksis er den dybde, hvormed den skarpe spids af kanylen stikkes ind i forventede injektionssteder, forskellige som følge af, at der bruges forskellig kraft, når der foretages injektioner. Den del af kanylen, der stikkes ind i en dyrekrop vil i tilfælde af en normal injektion skulle opfattes som den skarpe spids 102 ifølge nærværende frembringelse. Den eksponerede sektion 104 henviser normalt til den del, der er synlig, fordi den ikke trænger ind i kødet af dyret ved en normal injektion.In practice, the depth at which the sharp tip of the cannula is inserted into expected injection sites is different as a result of different forces being used when injecting. The part of the cannula inserted into an animal body would, in the case of a normal injection, be perceived as the sharp tip 102 of the present invention. The exposed section 104 usually refers to the part that is visible because it does not penetrate the flesh of the animal by a normal injection.
Imidlertid har ansøger fundet ud af, at når dyrene kæmper som følge af den smerte, der forårsages af injektionenerne, brækker alle nålekanylerne af på et sted, hvor samlingen 106 møder den eksponerede sektion 104, dvs et sted i nærheden af lokalitet A. Nålekanylen brækkes nemt af, og det skyldes, at dette sted er det kraftbærende punkt af kanylen, og det udsættes for påvirkning fra en stor kraft, når kanylen svinger i tværretningen, medens nåleholderen holdes fast på plads.However, applicant has found that when the animals struggle as a result of the pain caused by the injections, all the needle needles break off at a site where the assembly 106 meets the exposed section 104, i.e., a site near site A. The needle cannula is broken easily, and this is because this location is the force-bearing point of the cannula, and it is subjected to great force as the cannula swings in the transverse direction while the needle holder is held in place.

Efter knækket vil den afbrækkede kanyle med den skarpe spids 102 inde i dyrets krop gradvist og fuldstændigt bevæge sig ind i kroppen gennem nålestikket.After the crack, the broken cannula with the sharp tip 102 inside the animal's body will gradually and completely move into the body through the needle connector.
Ved videre analyse har det vist sig, at årsagen til, at den afbrækkede kanyle bevæger sig ind i kroppen er, at kanylen har samme dimension eller tager gradvist til fra sin skarpe ende og i retning opad mod bundenden. Formålet med at udforme frembringelsen har været at ændre denne ensartede dimension eller den gradvise tiltagen ved at tilføje i det mindste et blokeringselement på væggen af kanylen, således at den udvendige diameter af blokeringselement ikke får adgang gennem det nålestik, der laves i huden af den skarpe spids, hvorved nålekanylen forhindres i at bevæge sig fremad og ind i kroppen.Upon further analysis, it has been found that the cause of the broken cannula moving into the body is that the cannula has the same dimension or gradually increases from its sharp end and toward the bottom end. The purpose of designing the production has been to change this uniform dimension or the gradual measure by adding at least one blocking element to the wall of the cannula so that the outside diameter of the blocking element is not accessed through the needle plug made in the skin of the sharp tip, thereby preventing the needle cannula from moving forward and into the body.
Der henvises nu til fig. 2, hvorpå der vises et skematisk diagram over nålen til veterinær brug ifølge udførelsesformerne for den foreliggende frembringelse. For at forhindre nålekanylen i at bevæge sig ind i kødet, efter at den er brækket af, tilvejebringes der med den foreliggende frembringelse i det mindste et blokeringselement 1042 på væggen af kanylen, svarende til den eksponerede sektion 104. Og blokelementet/blokelementerne rager ud fra væggen.Referring now to FIG. 2, there is shown a schematic diagram of the needle for veterinary use according to the embodiments of the present invention. In order to prevent the needle cannula from moving into the meat after it is broken off, at present there is provided at least one blocking element 1042 on the wall of the cannula corresponding to the exposed section 104. And the block element (s) protrude from the wall.
Formen af blokelementet 1042 kan være, men er ikke begrænset til at være et udragende sted, en udragende klump, en båndlignende eller stanglignende komponent.The shape of the block element 1042 may be, but is not limited to, a protruding place, a protruding lump, a band-like or rod-like component.
Ifølge en udførelsesform for den foreliggende frembringelse er faconen af blokelementet ringformet eller delvist ringformet i tværretningen omkring væggen af nålekanylen.According to one embodiment of the present invention, the shape of the block element is annular or partially annular in the transverse direction around the wall of the needle cannula.
Ifølge en udførelsesform for den foreliggende frembringelse er blokerings-elementet integreret med kanylens væg. Det betyder, at der er tilvejebragt en 5 5DK 2009 00048 U3 udragende del i den form, der bruges til at støbe nålekanylen, med hvilken del blokeringselementet støbes.According to an embodiment of the present invention, the blocking element is integrated with the wall of the cannula. This means that a 5 5DK 2009 00048 U3 protruding part is provided in the mold used to mold the needle cannula with which the blocking member is molded.
Ifølge en udførelsesform for den foreliggende frembringelse kan blokeringselementet svejses eller nittes fast på væggen af kanylen svarende til den eksponerede sektion.According to one embodiment of the present invention, the blocking member may be welded or riveted to the wall of the cannula corresponding to the exposed section.
Ifølge en udførelsesform for opfindelsen kan blokeringselementet være tilvejebragt glidbart på væggen af kanylen svarende til den eksponerede sektion, for eksempel kan blokeringselementet klemmes fast omkring væggen med en elastisk klemring. Generelt er brudfladen af den brækkede kanyle uregelmæssigt afbrækket, hvilket betyder, at brudfladen har en udvendig diameter, som er større end den gennemsnitlige, udvendige diameter af kanylen, så det glidbart samlede blokeringselement kan ikke glide af kanylen.According to an embodiment of the invention, the blocking element may be provided slidably on the wall of the cannula corresponding to the exposed section, for example, the blocking element may be clamped around the wall with an elastic clamping ring. Generally, the rupture surface of the ruptured cannula is irregularly ruptured, which means that the rupture surface has an outside diameter greater than the average outside diameter of the cannula, so that the slidably total blocking member cannot slip from the cannula.
Ifølge en udførelsesform for opfindelsen kan blokeringselementet coates med en farve, som er forskellig fra den farve, som injektionsstedet har. For eksempel kan en skarp, klar gul farve hjælpe til med at skelne de dyr som har de afbrækkede nålekanyler i kroppene, fra de, som ikke har.According to an embodiment of the invention, the blocking element can be coated with a color different from the color of the injection site. For example, a sharp, clear yellow color can help distinguish the animals that have the broken needle needles in the bodies from those that do not have.
Fortrinsvis installeres blokeringselementet på den ene ende af den eksponerede sektion, nærmest samlingen, så det ikke udgør en forhindring for den skarpe spids og er nem at behandle.Preferably, the blocking member is installed at one end of the exposed section, closest to the joint, so that it does not impede the sharp tip and is easy to treat.
Det er klart, at nålen og nålekanylen til veterinær brug og med blokeringselementet ifølge den foreliggende opfindelse kan afholde den afbrækkede nål fra at bevæge sig fuldstændigt ind i injektionsstedet som følge af, at den udvendige diameter af elementet er større end nålestikket, og med blokelementet befinder en del af den afbrækkede nål sig uden for dyrets krop. Det gælder desuden, at når den farve, som påføres elementerne, er forskellig fra farven af dyret, kan de afbrækkede nåle nemt tages ud, hvilket reducerer den DK 2009 00048 U3 6 smerte, som dyrene oplever, og den arbejdsbelastning, som påhviler slagterierne og Foodstuffs Inspection Center.It is to be understood that the needle and needle cannula for veterinary use and with the blocking member of the present invention can prevent the broken needle from moving fully into the injection site as the outside diameter of the member is larger than the needle plug and with the block member being part of the broken needle extends outside the animal's body. In addition, when the color applied to the elements is different from the color of the animal, the broken needles can be easily removed, reducing the pain experienced by the animals and the workload of the slaughterhouses and Foodstuffs Inspection Center.
