Definitions
- the invention relates to a teat needle for administering an injection medium into a teat canal in the udder of a milking animal such as a cow or goat.
- a similar teat needle is known from BE-1005479 , for example.
- the teat needle has a thin tapering shaft that slides into the teat canal of the udder.
- the length of the needle shaft is such that when it is fully inserted into the teat canal, a medicine or salve can be injected directly into the udder.
- the teat needle is connected to a container that is filled with a specific quantity of the medicine or salve.
- the teat needle delimits a through flow canal with a forward facing discharge opening.
- the disadvantage of this is that ease of use and the animal-friendliness of the teat needle leaves to be desired. It may occur that when the needle shaft is inserted into the teat canal it meets a certain resistance. It may also be the case that the teat canal can suffer injury when the needle shaft is inserted. This happens especially if during manufacture membranes or burrs are left on the needle shaft on, for example, the discharge opening. There is a risk that these membranes or burrs will cut into the flesh internally. Wounds of this sort are painful for the animal and can lead to serious infection and to contamination of the milk that is withdrawn from the teat after treatment with the teat needle. Wounds of this sort also lead to financial loss for the farmer. In addition the discharge opening may get blocked during insertion into the teat canal. The needle shaft with its forward facing discharge opening scrapes free, as it were, all types of material that it encounters on the wall of the teat canal, and the material attempts to find a way into the interior of the flow canal via the discharge opening.
- a teat needle is known from GB-914,131 .
- This teat needle is designed for applying antibiotics to an infected and damaged teat canal, and if required can remain in the teat canal if this is deemed necessary for healing.
- the needle shaft has both a forward facing discharge opening and a lateral facing discharge opening.
- the lateral facing discharge opening reduces the problem of blockage, the forward facing discharge opening still has the above-mentioned disadvantages.
- US 4,236,520 discloses a flexible fluid drain or injection tube for insertion into a teat of an animal's udder.
- the injection tube comprises an elongated tubular body with an inlet opening at a bottom end part and a closed opposite end at an upper end part. The closed end is formed by a solid, rounded, tapered tip.
- Inside the tubular body an axial bore is present which connects to the inlet opening.
- two elongated slot-shaped outlet openings are present which connect to the bore. Those outlet openings are provided at axially different height positions along the tubular body and open out in opposite sideways directions.
- the aim of the invention described below is to remove at least partially the above-mentioned disadvantages or to provide a usable alternative.
- the aim of the invention is to create a user-friendly teat needle that is relatively cheap and simple to manufacture and which does not easily lead to wounding of the teat canal.
- the teat needle comprises an elongated needle shaft with a distal end piece that slides into the teat canal.
- a flow canal extends, which in the distal end piece connects to one or more laterally placed discharge openings.
- a protective end wall is provided which at least partially closes off the flow canal in the forward direction.
- This protective end wall is located here in the extension of the flow canal and thereby at least partially covers the distal end of the flow canal in the axial direction.
- the protective end wall in combination with one or more laterally positioned discharge openings makes it advantageously possible during manufacture of the needle shaft as an injection moulding product to work with connecting mould cores within the outer circumference of the needle shaft.
- one or more mould cores can be connected for the forming of the one or more outlet openings.
- any membranes or burrs that remain after manufacture then advantageously come to lie on these transitions over the wall thickness of the needle shaft within the outer circumference of the needle shaft. There the membranes and burrs cannot, or can hardly, lead to injury to the animal on insertion into its teat canal.
- the one or more laterally positioned discharge openings extend in an axial direction next to cut outs in the protective end wall.
- the injection medium will not only be injected out of the needle shaft laterally, but also by being slightly directed forwards, flow into the teat.
- this design makes it possible for the above mentioned mould cores to approach each other in an axial direction, during positioning in a mould cavity corresponding to the needle shaft, until the intended end position is reached, in which the mould cores partially come to rest against each other laterally at the transition(s) between the flow canals and the discharge opening(s).
- At least two, in particular three, discharge openings are distributed laterally around the circumference of the needle shaft.
- the protective end wall is integrally formed on the distal end section of the needle shaft.
- the needle shaft can be manufactured from various materials, such as metal or plastic.
- the needle shaft is preferably manufactured from plastic in an injection moulding process. If required the needle shaft can be assembled from various materials that can be prepared, for example, in a dual-component injection moulding process in one step.
- the invention also relates to a method for the manufacture of the teat needle as well as the use of the teat needle.
- the syringe 1 comprises a syringe body 2 with a cylindrical section 3 with an axial direction on which a distal end 3a and a proximal end 3b can be distinguished.
- the syringe 1 comprises a piston element 5 with a piston rod 6 and a piston 7.
- the free end of the piston rod 6 ends in a thumb support 8 and also has a cylindrical wall section.
- the piston 7 is an integral part of the piston element 5 and is provided with two elastic deformable ring-shaped wall sections 11.
- the piston 7 is dimensioned in such a way that in an assembled state it presses with its wall sections 11 to form a seal against the internal circumference of the cylindrical part 3.
- the radial external dimensions of the piston 7 are basically the same as the radial internal dimensions of the cylindrical part 3.
- the syringe 1 comprises an integrally formed assembly of a teat needle 12 that is connected to a break element 14 by means of weakened wall sections 13 (see also figure 6 and 7 ).
- This assembly is designed to be broken during assembling, with the break element 14 and the teat needle 12 being connected successively in their respective end positions with the syringe body 2 (see figure 2 ).
- break element 14 After assembling the break element 14 is designed to serve as a piston seal together with compressible cams provided on the piston rod 6.
- the teat needle 12 is destined to form a nozzle on the distal end 3a and must be inserted into the syringe body 2 from the proximal end 3b. At the location of the distal end 3a the teat needle 12 can be firmly attached to the syringe body 2. In the embodiment shown this occurs by means of a snap connection with complimentary inter-gripping wall sections, in particular, a tongue groove connection (see figure 2 ).
- the teat needle 12 comprises an elongated needle shaft 20 that is implemented here as a conical tapering distal end piece.
- a conical tapering flow canal 21 extends in an axial direction.
- the flow canal 21 discharges into three laterally positioned discharge openings 22 cut-out in the shaft wall that are symmetrically positioned around the circumference.
- the tip of the teat needle 12 is provided with a protective end wall 24.
- the protective wall 24 lies in the prolongation of the flow canal 21 and fully covers in the axial direction.
- the protective wall 24 is integrally shaped with the needle shaft 20.
- the discharge openings 22 extend in the axial direction into cut-outs 26 positioned sideways of the protective wall 24. In this way there is formed as it were a cylindrical core section 27 that is connected to the rest of the needle shaft 20 by ribs 28.
- Both the core section 27 and the ribs 28 of the protective wall 24 are constructed with a radius, by which a rounded tip is obtained.
- the teat needle 12 is made from plastic, especially PE, PP and/or TPE. If required parts of the teat needle 12, for example the needle shaft 20, the ribs 28 and the protective wall 24 with the respect to the rest of the teat needle 12 can be made from various materials that can be manufactured for example in a dual-component injection moulding process.
- This nozzle seal 30 is here formed by a protective cap 31 that is formed integrally on the syringe body 2 by a weakened peripheral wall section 32.
- the protective cap 31 is manufactured in two parts with the two parts 31a and 31b being connected together by a weakened peripheral wall section 33. The makes it possible to remove only the foremost part 31a, or also the rearmost part 31b. This gives the user the possibility to free up a longer or shorter part of the needle shaft 20 of the teat needle 12 for insertion in a body part.
- the protective cap 31 of the nozzle seal 30 is constructed in such a way that with its front part 31 it lies sealing against the needle shaft 20 of the teat needle 12.
- the protective cap 31 and the teat needle 12 are dimensioned in such a way that in the assembled state a small chamber is created between the tip of the teat needle 12 and the protective cap 31.
- the protective cap 31 is designed with a basically cylindrical cavity or with a cavity that has a smaller cone angle than that of the needle shaft 20. This ensures that in the assembled state on the one hand a small chamber is formed around the tip while on the other hand a sealing takes place between the peripheral wall of the needle shaft 20 and the protective cap 31.
- the various parts of the syringe can be given various forms and dimensions.
- another type of tamper evident construction can also be applied to seal and/or close off the distal end in a reliable way.
- the teat needle integrally onto the syringe body or use a teat needle that can be connected from the outside with the distal end of the syringe.
- the teat needle freely in combination with another type of syringe or supply unit.
- the discharge openings can also be provided at a lower level along the needle shaft and vary in number. The protective wall will then be able to spread over the entire tip.
- a teat needle is provided that can be manufactured easily and cheaply and which lends itself very well to the introduction of an injection medium into the teat of an udder of a milking animal such as cow or goat, for example a salve with antibiotic qualities, or a curable medium that can seal the teat temporarily.

Abstract
Description
- The invention relates to a teat needle for administering an injection medium into a teat canal in the udder of a milking animal such as a cow or goat.
- A similar teat needle is known from
BE-1005479 - The disadvantage of this is that ease of use and the animal-friendliness of the teat needle leaves to be desired. It may occur that when the needle shaft is inserted into the teat canal it meets a certain resistance. It may also be the case that the teat canal can suffer injury when the needle shaft is inserted. This happens especially if during manufacture membranes or burrs are left on the needle shaft on, for example, the discharge opening. There is a risk that these membranes or burrs will cut into the flesh internally. Wounds of this sort are painful for the animal and can lead to serious infection and to contamination of the milk that is withdrawn from the teat after treatment with the teat needle. Wounds of this sort also lead to financial loss for the farmer. In addition the discharge opening may get blocked during insertion into the teat canal. The needle shaft with its forward facing discharge opening scrapes free, as it were, all types of material that it encounters on the wall of the teat canal, and the material attempts to find a way into the interior of the flow canal via the discharge opening.
- In addition a teat needle is known from
GB-914,131 -
US 4,236,520 discloses a flexible fluid drain or injection tube for insertion into a teat of an animal's udder. The injection tube comprises an elongated tubular body with an inlet opening at a bottom end part and a closed opposite end at an upper end part. The closed end is formed by a solid, rounded, tapered tip. Inside the tubular body an axial bore is present which connects to the inlet opening. Along a cylindrical section of the tubular body two elongated slot-shaped outlet openings are present which connect to the bore. Those outlet openings are provided at axially different height positions along the tubular body and open out in opposite sideways directions. - The injection tube of
US 4,236,520 , upon which prior art the two part form of claim 1 is based, still leaves to be desired, in terms of manufacturing, animal friendliness and ease of use. - The aim of the invention described below is to remove at least partially the above-mentioned disadvantages or to provide a usable alternative. In particular the aim of the invention is to create a user-friendly teat needle that is relatively cheap and simple to manufacture and which does not easily lead to wounding of the teat canal.
- This aim is achieved by a teat needle in accordance with claim 1. In this case the teat needle comprises an elongated needle shaft with a distal end piece that slides into the teat canal. Through the needle shaft in axial direction a flow canal extends, which in the distal end piece connects to one or more laterally placed discharge openings. A protective end wall is provided which at least partially closes off the flow canal in the forward direction. This protective end wall is located here in the extension of the flow canal and thereby at least partially covers the distal end of the flow canal in the axial direction. This has the advantage that a teat needle is obtained that can be manufactured with a protective end wall that connects to the needle shaft via gradual transition. Advantageously a punching or scraping action of the needle shaft can therefore be avoided. This diminishes the risk of blocking of the teat needle. In addition it simplifies the insertion of the needle shaft into the teat canal and prevents injury to the wall thereof.
- The provision of the protective end wall in combination with one or more laterally positioned discharge openings makes it advantageously possible during manufacture of the needle shaft as an injection moulding product to work with connecting mould cores within the outer circumference of the needle shaft. In particular on the, for example, cylindrical or conical extending outer circumference wall of a mould core for the formation of the flow canal, one or more mould cores can be connected for the forming of the one or more outlet openings. As contact between the mould cores then takes place at the point of the transitions between the flow canal to be formed and the laterally placed discharge openings to be formed, any membranes or burrs that remain after manufacture then advantageously come to lie on these transitions over the wall thickness of the needle shaft within the outer circumference of the needle shaft. There the membranes and burrs cannot, or can hardly, lead to injury to the animal on insertion into its teat canal.
- The one or more laterally positioned discharge openings extend in an axial direction next to cut outs in the protective end wall. During injection the injection medium will not only be injected out of the needle shaft laterally, but also by being slightly directed forwards, flow into the teat. In addition, this design makes it possible for the above mentioned mould cores to approach each other in an axial direction, during positioning in a mould cavity corresponding to the needle shaft, until the intended end position is reached, in which the mould cores partially come to rest against each other laterally at the transition(s) between the flow canals and the discharge opening(s).
- In a preferred embodiment at least two, in particular three, discharge openings are distributed laterally around the circumference of the needle shaft. By providing these, moreover, symmetrically around the needle shaft, folding of the wall sections of the teat canal into the discharge openings towards the inside during insertion of the needle shaft can be prevented. This prevents that any membranes or burrs at the transitions of the flow canal to the discharge openings may still lead to injury.
- In particular the protective end wall is integrally formed on the distal end section of the needle shaft. The needle shaft can be manufactured from various materials, such as metal or plastic. The needle shaft is preferably manufactured from plastic in an injection moulding process. If required the needle shaft can be assembled from various materials that can be prepared, for example, in a dual-component injection moulding process in one step.
- Further preferred implementations are laid down in the sub-claims. The invention also relates to a method for the manufacture of the teat needle as well as the use of the teat needle.
- The invention will be further explained using the attached drawings in which:
-
Fig. 1 is a schematic view in perspective of an embodiment of a syringe with teat needle in accordance with the invention before assembly; -
Fig. 2 is a partially cut away view corresponding tofigure 1 with a teat needle and break element incorporated into the syringe body; -
Fig. 3 is a view corresponding tofigure 2 with a piston element mounted in the syringe body; -
Fig. 4 is a view corresponding tofigure 2 with broken nozzle sealing and fully depressed piston element; -
Fig. 5 is a partial view at a larger scale offigure 4 ; -
Fig. 6 is an enlarged view of the assembly of teat needle with break element fromfigure 1 ; and -
Fig. 7 is a partially exploded view of the teat needle infigure 6 . - In
figure 1 the entire syringe is given the reference numeral 1. The syringe 1 comprises a syringe body 2 with acylindrical section 3 with an axial direction on which adistal end 3a and aproximal end 3b can be distinguished. In addition the syringe 1 comprises apiston element 5 with apiston rod 6 and apiston 7. The free end of thepiston rod 6 ends in athumb support 8 and also has a cylindrical wall section. Thepiston 7 is an integral part of thepiston element 5 and is provided with two elastic deformable ring-shapedwall sections 11. Thepiston 7 is dimensioned in such a way that in an assembled state it presses with itswall sections 11 to form a seal against the internal circumference of thecylindrical part 3. In this respect the radial external dimensions of thepiston 7 are basically the same as the radial internal dimensions of thecylindrical part 3. - As a further component preceding assembling, the syringe 1 comprises an integrally formed assembly of a
teat needle 12 that is connected to abreak element 14 by means of weakened wall sections 13 (see alsofigure 6 and7 ). This assembly is designed to be broken during assembling, with thebreak element 14 and theteat needle 12 being connected successively in their respective end positions with the syringe body 2 (seefigure 2 ). - After assembling the
break element 14 is designed to serve as a piston seal together with compressible cams provided on thepiston rod 6. - The
teat needle 12 is destined to form a nozzle on thedistal end 3a and must be inserted into the syringe body 2 from theproximal end 3b. At the location of thedistal end 3a theteat needle 12 can be firmly attached to the syringe body 2. In the embodiment shown this occurs by means of a snap connection with complimentary inter-gripping wall sections, in particular, a tongue groove connection (seefigure 2 ). - The
teat needle 12 comprises anelongated needle shaft 20 that is implemented here as a conical tapering distal end piece. In the needle shaft 20 a conicaltapering flow canal 21 extends in an axial direction. Theflow canal 21 discharges into three laterally positioneddischarge openings 22 cut-out in the shaft wall that are symmetrically positioned around the circumference. - According to the invention the tip of the
teat needle 12 is provided with aprotective end wall 24. Theprotective wall 24 lies in the prolongation of theflow canal 21 and fully covers in the axial direction. Theprotective wall 24 is integrally shaped with theneedle shaft 20. Thedischarge openings 22 extend in the axial direction into cut-outs 26 positioned sideways of theprotective wall 24. In this way there is formed as it were acylindrical core section 27 that is connected to the rest of theneedle shaft 20 byribs 28. - Both the
core section 27 and theribs 28 of theprotective wall 24 are constructed with a radius, by which a rounded tip is obtained. - The
teat needle 12 is made from plastic, especially PE, PP and/or TPE. If required parts of theteat needle 12, for example theneedle shaft 20, theribs 28 and theprotective wall 24 with the respect to the rest of theteat needle 12 can be made from various materials that can be manufactured for example in a dual-component injection moulding process. - On the
distal end 3a of the syringe 2 a seal is provided of the nozzle formed by theteat needle 12. Thisnozzle seal 30 is here formed by a protective cap 31 that is formed integrally on the syringe body 2 by a weakenedperipheral wall section 32. The protective cap 31 is manufactured in two parts with the twoparts peripheral wall section 33. The makes it possible to remove only theforemost part 31a, or also therearmost part 31b. This gives the user the possibility to free up a longer or shorter part of theneedle shaft 20 of theteat needle 12 for insertion in a body part. - The protective cap 31 of the
nozzle seal 30 is constructed in such a way that with its front part 31 it lies sealing against theneedle shaft 20 of theteat needle 12. In addition the protective cap 31 and theteat needle 12 are dimensioned in such a way that in the assembled state a small chamber is created between the tip of theteat needle 12 and the protective cap 31. This has the advantage that a small quantity of injection medium can gather around the tip via thedischarge openings 22 and/or the cut-outs 26, with the small quantity of injection medium after removal of the protective cap 31 serving directly as a friction reducing lubricant during insertion of the teat needle in, for example, the udder of an animal. The protective cap 31 is designed with a basically cylindrical cavity or with a cavity that has a smaller cone angle than that of theneedle shaft 20. This ensures that in the assembled state on the one hand a small chamber is formed around the tip while on the other hand a sealing takes place between the peripheral wall of theneedle shaft 20 and the protective cap 31. - In addition to the embodiments shown many other variants are possible. This means that the various parts of the syringe can be given various forms and dimensions. Instead of the integrally formed nozzle seal at the distal end another type of tamper evident construction can also be applied to seal and/or close off the distal end in a reliable way. In this way it is also possible to form the teat needle integrally onto the syringe body or use a teat needle that can be connected from the outside with the distal end of the syringe. It is also possible to use the teat needle freely in combination with another type of syringe or supply unit. The discharge openings can also be provided at a lower level along the needle shaft and vary in number. The protective wall will then be able to spread over the entire tip.
- Thus according to the invention a teat needle is provided that can be manufactured easily and cheaply and which lends itself very well to the introduction of an injection medium into the teat of an udder of a milking animal such as cow or goat, for example a salve with antibiotic qualities, or a curable medium that can seal the teat temporarily.
