Definitions

  • the invention relates to an insemination catheter, in particular for Pigs, with a tubular catheter shaft, at its distal tip Shaped body with increased diameter dimensions compared to the shaft sits.
  • Such insemination catheters are intended for single use and will be then disposed of. They have a tubular shaft with a length of z. B. scarce 50 cm, with a molded body surrounding or forming its tip area for example 8 cm in length, which in the case of a pig catheter is preferably roughly helical on the outside, for example three to four threads with a thread pitch between 15 and 20 mm and a thread vertex radius of just over 5 mm.
  • This Screw molded body is used to screw the catheter tip forward the cervical occlusion cushions.
  • the insemination catheters are usually used apply a lubricant to prevent mucosal lesions.
  • the material consumption for the shaped body particularly in the case of a screw Shaped body with massive threads is for one use only Disposable product relatively high.
  • the molded body consists of at least a narrow, essentially radial web that is spaced apart its axially directed side surfaces of adjacent radial parts of the Web is attached to the shaft and has an outer envelope surface that the shape of the molded body.
  • the ratio of the thickness of the parts of the web to the Distances between the parts of the web are in the range 5: 1 to 1: 3, preferably to 1: 2.
  • the webs can have essentially the same thickness in the axial direction have and between them there can be essentially the same distances, with preferred dimensions specified in the claims.
  • the molded body of starting from its distal end, a cylindrical tube piece of a diameter of no more than 10 mm and a length of no less than 10 mm, and on it then a piece with the screw shape.
  • the microcapsules can e.g. B. be provided with a lubricant or with pharmaceutical substances, whereby the catheter itself as a vehicle for introducing active pharmaceutical ingredients or of lubricant.
  • the microcapsules can melt into the Injection molding can be introduced at a time when the temperature is already has dropped somewhat so that the capsules are not destroyed as a result.
  • the insemination catheters according to the invention can be manufactured in such a way that after cutting the shaft to a given length with your Introduces the tip area into a mold and the material of the fitting sprayed or foamed onto the catheter shade.
  • one accordingly designed tool shape e.g. B. injection mold
  • this is easily in the laminated design possible, with a core of the Shaped body allows the conclusion of the plastic material from web to web.
  • the spraying process is not suitable for all material combinations, however, it is possible, for example, if the catheter shaft consists of one Polyolefin such as polypropylene and the molded body made of TPE material (thermoplastic Elastomer). Another possible combination is that both parts consist of PVC.
  • insemination catheters it can also be useful for monitoring and steering to assign an endoscopy device, for example under Use of optical fibers running along the shaft as light guides and Image guides are installed.
  • a insemination catheter 1 for pigs consists of a catheter shaft according to FIG. 1 2 in the form of a tube made of polypropylene with an outside diameter of about 7 mm and an inner diameter of about 5 mm, and a molded body 3, which consists of a thermoplastic elastomer and in turn essentially from a front tube extension 4 and an adjoining one Screw coil 5 exists.
  • the molded body 3 sits on the distal tip of the Shaft 2, which is within the molded body 3 to close to its distal End 6 extends at the tip of the tubular extension 4.
  • the screw coil 5 is not a solid body but consists of one A large number of parallel disk-shaped webs 11, between which spaces 12 lie.
  • the disk-shaped webs 11 can each, for example Circular disk shape, but also a different, for example elliptical Shape, evidence. They are each eccentric in parallel radial planes arranged that the outer surface 13 of the helical shape of its outer surfaces results.
  • the individual disk-shaped webs 11 also not cylindrical, so that a stepped screw shape would be formed, but according to the local direction of the screw helix surface in stronger or less oblique. Only in the base and top of the gutter straight cylindrical surfaces are created.
  • the webs 11 are as thick as the gaps 12.
  • the disk-shaped webs 11 have one in the example shown Length of the helix 5 constant width of about 1 mm each and the spaces 12 are also about 1 mm wide. This results in Consideration of the materials used sufficient strength and compared to a solid material molded body a material saving in the Of the order of 1: 2.
  • the disk size of the webs 11 is at the two ends of the screw coil 5 smaller than most of its length, which is approximately 45 mm in total. This is followed by a length of about 25 mm of the distal end 6 Pipe extension 4 on.
  • this helix is significantly shortened and the length of the tubular extension significantly enlarged, with a correspondingly advantageous result with regard to the recovery of the infused seed.
  • This cheaper Dimensioning is made possible by the better grip of the laminated screw helix 5, which manages with fewer screw threads.
  • Fig. 4 shows an embodiment in which only one helical web 17 sits on the shaft 2 or on a helical core 18, with Web turns 19, the dimensioning and function of those of the disc-shaped Corresponds to webs 11.
  • the lamination of the shaped body or an essential part of the shaped body is not limited to helical shaped bodies, but also to shaped bodies other design makes sense.
  • Fig. 5 shows a compared to Fig. 1 by a slice thickness-space ratio 2: 1 modified insemination catheter, in which the webs 11 approx. Are 1.2 mm thick and the distances 12 are approximately 0.6 mm, and with the additional Peculiarity that in the material of the tubular extension 4 and in some Circumference of the webs of the helix 5 microcapsules 21 are installed, with the help of pharmacologically active substances and / or lubricants that facilitate the insertion of the catheter into the genital tract. These microcapsules 21 are covered by moisture, friction and / or pressure Release of the substances contained therein opened, and then unfold their effect.
  • the shaped body 3 in turn laminated in Executed helical shape, the envelope surface 13, which results from the Exterior surfaces of the disc-shaped webs 11, a threaded valley line 23 and has a thread apex line 24.
  • the apex line 24 lies here on a cone 25, the smallest diameter at the distal end and whose largest diameter is at the proximal end of the molded body 3.
  • the individual webs 11 in the form of circular disks thus have a rearward one increasing diameter. This in turn results in an improved Sealing even with different cervical sizes, whereby the elastically bendable lamellar webs cause a good seal that keeps the flow of the infused seed in the uterus.
