Description
BAC~iGROU~D AND SUMMARY Q~' TIII~ INV~NTION
This invention relates in general to animal breeding and, more particularly, to an instrument for promoting artificial breeding oE dogs.
Resort to the practice of artificial insemination for breeding o dogs has become increasingly widespread.
I-lowever, heretofore the percentage of fer~ilization th~oug}l such eEforts has been recognizedly consistently low. Various techniques have been attempted in order to enhance the probability of success but none have to the present time been of any marked effectiveness. Thus, the usual techni~ue is to insert a tube into the vagina of the dog for discharge therein of the seminal matter. The tube is withdrawn and the dog's hindquarters are elevated for a limited period of time in order that gxavity may assist the flow of semen for ova ~ertilization.
It is believed that to the present time the approach to the artificial breeding of dogs has not properly taken into account the necessity of stimulating the female being treated so as to bring abou-t a physical and psychological reactior comparable to that occurring during natural mating.
Furthermore, there has been a total failure to note that current techniques of art:ificial insemination ignore the importance of the inter-reactive phsysiological phenomenon peculiar to the union o~ male and female dogs during mating which is referred to commonly as a "tie", or "tie knot".
During normal copulation the female's constrictor vestibuli muscles are contracted and tiyhten behind the bulbus glandis of the male's penis and thereby prevent the male from dismounting for a period of about 10 to 20 minutes following initial ejaculation. Such tie causes a contraction or pulling ~"~
4~7 of the uterus which tends to promote seminal ~ovement as it is -thought that semen continues to flow from the male in -this interval. It will be appreciated that the female psychologically associates the sensations effected by the "tie" with the copulatory ac-t and thus is sexually prepared for promoting fertilization.
Therefore, it is an object of the present invention to provide an instrument useful in ar-tificial breeding, primarily of dogs~ but also of any other animals that may develop a "tie" during mating to cause the female vaginal musculature to simulate activity occurring during nature breeding.
It is another ob~ect of the present invention to provide an instrument oE the character stated which is adapted to assure of retention of artificially provided semen, preventing loss as is encountered with costly frequency, and thereby promoting fertilization.
It is a further object of the present invention to provide an instrumen~ o the character stated which is of simple construction for reliability of operation and is easily utilized, as by a veterinarian.
It is a still urther object of the present invention to provide an instrument of the character stated which may be economically produced so that the same may be disposed of after a single usage; and which in use serves to stimulate the female so as to generate the physical and psychological reactions attendant to the act of copulation thereby disposing her for the enhanced likelihood of fertilization~
Those objects are attained by the invention which contemplates an instrument for promoting artificial breeding of dogs which comprises an elongated body of phallic-simulative configuration fabricated of relatively sof-t, flexible material non-injurious to -the female and having a distal end and a proximal end, and a means defining a fluid inflatable chamber surrounding the body in the portion thereof adjacent to, but spaced from, the proximal end. The chamber relates to the body in a manner substantially corresponding to the relation-ship of the bulbus glandis to the penis of a male dog wl-th the chamber being spaced from the proximal end of the body a distance sufficient for engagement about the body, immediately adjacent the chamber, of the constrictor vesti~uli muscle of the female dog when the body is inserted within such female.
A source of fluid has means connecting it with the chamber, and a means causes the chamber to be inflated by the fluid for simulating an enyorged bulbus glandis, thereby developing a tie-forming interengagement be-tween the female and the instrument.
The invention also contemplates a method for promot1ng artificial breeding in dogs which comprises artificially inseminating a female dog, then inserting into the vagina of the dog the forward, phallic-simula~ive end portion of an elongated body having a surrounding fluid-inflatable chamber for disposition immediately distally of the constrictor vestibuli muscle of the female, then causing the chamber to be fluid-inflated for excitation of the vaginal musculature of the dog, whereby the constrictor vestibuli muscle contra~ts about the elongated body immediately rearwardly of the now inflated chamber developing a tie-forming relationship between the inflated chamber and the constrictor vestibuli muscle, thus permitting the chamber to remain inflated for a period of time approximating the lnterval for such tie during normal mating, then deflating the chamber, and then withdrawing the phallic-simulative end portion.

3a-Dl:S(~RIPTION OF Tl~ PE~FERI~D ~M:130DIMENT
Referrinc~ now by reference characters -to the drawings which illustrate the preferred embodiment of tlle present invention, A designates an artificial breeding instrument 1 designed primarily for use with dogs, but useful with any other animals that effect a "tie" durincJ copulation. Instrument A
comprises an elonga~ed member 1, generally simulativecf a dog penis, being of circular cross-~ection but at its distal end 2 being prefercibl~ tapered and closed. Member 1 is fabricated desirably of a suitable plastic whicll provides a relative soft, pliability or flexibility and may be of tubular form, having a lengthwise bore 3 which is open at the proximal end 4 thereofO Member 1 is of such leng~h and tex-ture so as to be non-.injurious to the accepting vaginal and cervical portions of the particular female dog and yet being of such relative proportions as to be sensorily stimulative in the manner of a natural phallus.
Near the proximal end 4, and in the order of approximately two-thirds of the distance from distal end 2, member 1 is surrounded by a thin-walled, inflatahle bulb or balloon 5 providing an expansible air chamber 6. At the opposite ends thereof bulb 5 is provided with aligned openings 7,8 and with the edges thereoE, as 7', 8', respcctivcly, turned inwardly or suitahle air-proof engagement with the outer face of member 1, such as by an appropriate adhesive or the like. Substantially centrally within the portion of member 1 encircled by bulb 5, an openincJ 9 is ormed in the wall thereo for extension therethrough of the outer end of a tube 10; said tube 10 progressing through member 1, thence outwardly proximal end 4 for ~ecurement to a conventional flexible fitting, generally denoted 11, for connection to an air ba~ 12. Provi~ed upon fitting 11 is a clamp 13 by the positioning of which fi~ting 11 may be closed to prevent air flow therethrouyh or purposes presently appearingO Air bag 12 together with fitting 11 ancl clamp 13 do not form a part of the prcsent invent.ion bu-t are disclosed or the purpose of demonstra-ting a convenient source of air Eor inflating bulb 5~ It is, of course, recognized tha-t there are numerous expedients provicling the desired portability for such ~urpose.
As pointed out hereinabove, instrument A is designed for utilization, primarily, with dogs for the purpose of enhancing the pxobability of fertilization in the practice of artificial insemination. Through a condition simulative of a "tie" which dogs uniquely develop during copulation, the emale will be caused to experience physical and psychological sensations associated with mating whereby she will be disposed for enhanced receptivity of the artificially provided sperm since she will eel that breeding is in fact taking place. Thus, near-reality will be caused, as distinguished from the unnatural procedures used heretoore in depositing sperm artificially within the female.
After a female dog has been artificially inseminated, as by the injection of sperm through the cervix and into the uterus by means of a conventional tube, inst.rument A is inserted into the vagina of the female until the bulb 5 is immediately above the constrictor vestibuli muscle of the female. Thereupon air bag 12 is compressed so as to orce `` air through tube 10 and into bulb 5 for efecting dilation thereof. Clamp 13 is then suitabl~ manipulated to prevent accidental return flow of air from bulb 5. Bulb 5 as thus in1ated simulates an engorged penile bulbus glandis and thus excites the female's constrictor vestibuli muscle to contract and tighten immediately behind the now inflated bulb 5 and thereby bring about a condition simulative of the "tie" which is developed by the copulating clogs, which under natural conclitions preven-ts the male from dismounting for a period of time as in -the order of 15 minutes. Such excitation of the vaginal musculature causing a contracting or a pulling of the uterus will thus conEo~n to, or closely approximate, the usual conditions developing during copulation and thereby conduce to fertilization.
Through the u-tiliæation oE instrument A the fernale is stimulated into a psychological, as well as a physical state, comparable to that experienced during natural copulation so that she is thus systemically prepared for successful insemination.
As stated hereinabove, instrurnent A through the inflation of bulb 5 successfully closes the va~ina as by the so-called "tie knot" development so that semen loss is inhibited~
Af~er a period of time corresponding to that normally involved has elapsed, such as 15 minutes, clamp 13 is manipulated 50 as to appropriately open fitting 11 and thereby allow return o air to bag 12 with consequent deflation oE
bulb 5 so that instrurnent A may be then withdrawn.
It is evident rom the foregoing that if desired member 1 forwardly of opening 9 could be formed of solid material. It is, of course, recoynized that instrument A
is producible in varying lengths and diameters so as to accormnodate each particular breed of dog~
Although bulb 5 has been disclosed hereinabove as being inflatahle by air, it should be recognized that any suitable type of fluid could be used whether gaseous or liquid. With liquids the instrument could easily be adapted or connection to a suitable source of water or the li]ce which rnight be preferably warmed~
