Description

この発明は、長期に亘り家畜の膣内に留め置かれる膣内留置装置に関するものである。 The present invention relates to an intravaginal indwelling device that is retained in the vagina of livestock for a long period of time.

家畜用膣内留置装置に関連した技術としては、例えば牛の分娩報知用の温度センサや、膣内に留置して発情周期同調剤を放出する膣内留置装置が提案されている（例えば特許出願文献１、特許出願文献２参照。）。   As a technique related to the vaginal indwelling device for livestock, for example, a temperature sensor for informing the delivery of cattle and an intravaginal indwelling device that is placed in the vagina and releases the estrous cycle synchronizer have been proposed (for example, patent applications). Reference 1 and Patent application reference 2).

特開平７−３１３５３７JP 7-313537

特表２００４−５２２５２８（Ｐ２００４−５２２５２８Ａ）Special table 2004-522528 (P2004-522528A)

家畜の膣内留置装置は、その留置装置にセンサを取り付け家畜の生体情報をモニターして、飼料管理、疾病の早期発見、発情検知、分娩予測等を行ったり、発情周期同調剤を放出して発情を同期化する装置としては有用であるが、それらの技術では膣内留置装置の不測の脱落と膣炎の発生の両方を防止することが困難であり、数日間の連続留置が限界である。例えば、スカート状に広がった弾性薄板からなる固定式係留部を持つ特許文献１記載の温度センサと、樹脂の弾性力を利用してT字形またはY字形に変形可能な開閉式係留部を持つ特許文献２記載の膣内滞留装置の何れも係留期間は長くても５日程度で長期係留を目的としておらず、１ヶ月以上の長期に亘って家畜の膣内に留め置くのに充分な係留力は有していない。   A veterinary indwelling device for livestock is equipped with a sensor attached to the indwelling device to monitor the biological information of the livestock and perform feed management, early detection of disease, estrus detection, delivery prediction, etc., and release an estrous cycle synchronizer. Although useful as a device to synchronize estrus, it is difficult to prevent both inadvertent removal of the vaginal indwelling device and the occurrence of vaginitis with these techniques, and continuous placement for several days is the limit . For example, a temperature sensor described in Patent Document 1 having a fixed mooring portion made of an elastic thin plate spreading in a skirt shape, and a patent having an open / close mooring portion that can be deformed into a T shape or a Y shape using the elastic force of resin. None of the vaginal retention devices described in Document 2 has a mooring period of about 5 days at the longest and is not intended for long-term mooring. Does not have.

これらは係留部の外径や長さを大きくしたり、膣壁との接触面積を大きくしたりすることで、膣内留置装置の膣内からの脱落を防止することは可能であっても、膣壁に過度の刺激を与えたり、膣内体液の膣外への排出を妨げることに起因する膣炎の発生を防止することが出来ない。そのため短期的には膣内に留置することは出来ても、家畜の健康を損なわずに長期間家畜の膣内へ留置することは困難である。 Even though these can increase the outer diameter and length of the mooring part or increase the contact area with the vagina wall, it is possible to prevent the indwelling device from falling out of the vagina, It is impossible to prevent the occurrence of vaginitis due to excessive stimulation of the vagina wall or obstruction of the discharge of body fluid from the vagina outside the vagina. Therefore, although it can be placed in the vagina in the short term, it is difficult to place it in the vagina of the livestock for a long time without impairing the health of the livestock.

この発明は、上記課題を解決した家畜用膣内留置装置を提供することを目的とするものであり、この発明の家畜用膣内留置装置は、家畜の膣道を通過可能な細長い筒状容器と、筒状容器の長手方向の両端領域にそれぞれ配置され家畜の膣道を通過可能に曲げたたまれて膣内に挿入された後に前記筒状容器の長手方向軸線から外方へ延在するよう配置された、筒状容器の円周方向に沿って延びる環状形状の複数の金属製ワイヤからなる翼部とを具えることを特徴とするものである。
かかる家畜用膣内留置装置にあっては、翼部は自然状態では図４(a)に示すとおり展開された状態であるが挿入時に、翼部を曲げたたむことにより家畜の膣道を通過可能な細長い形状とされ、この状態で膣道の奥の膣内に該膣内留置装置が挿入された後は、その翼部が展開して膣壁と接触し膣内に係留される。
従って、この発明の家畜用膣内留置装置によれば、翼部は環状形状をしており、且つ適度に膣壁の動きにより変形することによって、膣壁への過度の刺激を押さえることが出来、膣壁を傷つけることがないため、膣炎の発生を防ぐことが出来る。また翼部は筒状容器の両端に配置されるため、膣内で展開すると前記筒状容器は膣壁に接触することなく宙に浮いた状態となり、更に翼部は金属製ワイヤからなるため、体液の自然排出を物理的に遮ることなくその通路を確実に確保することが出来るため、膣内体液の滞留に起因した膣炎の発生を防止できる。膣壁は膣内の体液により常に湿潤され、その体液の排出により雑菌や老廃物が洗い流されることが重要であり、膣内膣内留置装置と膣壁との接触面積は少ないほど、膣壁と体液との接触を可能とし、且つ体液の自然排出を可能とすることができる。しかも本発明の家畜用膣内膣内留置装置によれば翼部の枚数や線径を調整することにより容易に係留力を調整することが可能であるため、一種類のみあるいは僅かな種類で、膣サイズの個体差や怒責（きばること）による膣内圧の変化に応じて適切な係留力を得ることができる。
膣内留置の間、材料の保全性に対する生理学的影響を最小とするために本発明の家畜用膣内留置装置はコーティングされていてもよい。
An object of the present invention is to provide a vaginal indwelling device for livestock that solves the above-mentioned problems, and the vaginal indwelling device for livestock of the present invention is an elongated cylindrical container that can pass through the vaginal tract of livestock. And are arranged in both end regions in the longitudinal direction of the cylindrical container, bent so as to be able to pass through the vaginal tract of livestock, and after being inserted into the vagina, extend outward from the longitudinal axis of the cylindrical container And a wing portion made of a plurality of annular metal wires extending in the circumferential direction of the cylindrical container .
In such a vaginal indwelling device for livestock, the wings are deployed as shown in FIG. 4 (a) in the natural state, but can be passed through the vaginal tract of livestock by bending the wings when inserted. In this state, after the intravaginal indwelling device is inserted into the vagina at the back of the vaginal tract, its wings expand and come into contact with the vagina wall to be anchored in the vagina.
Therefore, according to the veterinary indwelling apparatus for livestock of the present invention, the wing portion has an annular shape and can be suppressed by excessively irritating to the vagina wall by being appropriately deformed by the movement of the vagina wall. Because it does not damage the vagina wall, it can prevent the occurrence of vaginitis. Also, because the wings are arranged at both ends of the cylindrical container, when deployed in the vagina, the cylindrical container floats in the air without contacting the vagina wall, and the wings are made of metal wire, Since the passage can be surely secured without physically blocking the natural discharge of bodily fluids, it is possible to prevent the occurrence of vaginitis due to the stay of bodily bodily fluids. It is important that the vaginal wall is always moistened by body fluids in the vagina, and that germs and waste products are washed away by the discharge of the body fluids.The smaller the contact area between the intravaginal indwelling device and the vagina wall, the more It is possible to make contact with body fluids and to allow natural discharge of body fluids. Moreover, according to the veterinary vaginal indwelling apparatus for livestock of the present invention, it is possible to easily adjust the mooring force by adjusting the number of wings and the wire diameter, so only one type or only a few types, An appropriate mooring force can be obtained according to changes in the vaginal pressure due to individual differences in vagina size and anger.
During vaginal placement, the veterinary veterinary placement device of the present invention may be coated to minimize the physiological impact on material integrity.

またこの発明においては、翼部の金属製ワイヤを超弾性特性を具える形状記憶合金にすることができる。形状記憶合金は、オーステナイト相からマルテンサイト相への変態が生じるような温度以下に冷却されたとき、元の形状から新たな形状に容易に変形し得る。変態が始まる温度は、通常Ｍｓと呼ばれ、変態が終わる温度は、Ｍｆと呼ばれる。このように変形した合金は、オーステナイト相にもどり始める温度Ａｓまであたためられたとき、その元の形状にもどり始める。このオーステナイト相への変態過程、つまり形状回復過程が完了する温度は、Ａｆと呼ばれる。形状記憶効果を示す多くの合金は、Ａｆ以上の温度でオーステナイト相に外力を加えると応力誘起マルテンサイト相に変態し、外力を取り除くことにより直ちに元のオーステナイト相に戻り、超弾性と呼ばれるゴムのような弾力性を示す。このため、本発明の家畜用膣内留置装置の翼部を超弾性特性を示す形状記憶合金とすることにより、翼部は超弾性による変形回復力により、適切な係留力をえることができ、過度に膣壁を刺激することがなく、長期に渡り係留しても膣炎の発生を防ぐことが出来る。また、塑性変形をおこすことがないため、繰り返し使用することが出来る。 In the present invention, the metal wire of the wing portion can be made into a shape memory alloy having superelastic characteristics. A shape memory alloy can be easily deformed from its original shape to a new shape when cooled to below a temperature at which transformation from the austenite phase to the martensite phase occurs. The temperature at which transformation begins is usually called M s, and the temperature at which transformation ends is called M f . The deformed alloy as is when warmed to a temperature A s to begin returning to the austenitic phase begins to return to its original shape. The temperature at which the transformation process to the austenite phase, that is, the shape recovery process is completed is called Af . Many alloys exhibiting a shape memory effect transform into a stress-induced martensite phase when an external force is applied to the austenite phase at a temperature of Af or higher, and immediately return to the original austenite phase by removing the external force. It shows elasticity like this. For this reason, by using the shape memory alloy showing superelastic characteristics as the wing part of the vaginal indwelling device for livestock of the present invention, the wing part can obtain an appropriate mooring force due to the deformation recovery force due to superelasticity, It does not irritate the vagina wall excessively and can prevent vaginitis from being moored for a long time. Moreover, since it does not cause plastic deformation, it can be used repeatedly.

さらに翼部に使用する前記形状記憶合金をニッケル−チタン合金にすることにより、マルテンサイト相からオーステナイト相への変態終了温度Ａｆを体温付近に設定することが容易である。例えば、ニッケル濃度が56wt%のニッケル−チタン合金を480℃で熱処理するとマルテンサイト相からオーステナイト相への変態終了温度Ａｆを30℃から35℃にすることが出来る。更に生体適合性が非常に良好であるため、長期間膣内に係留しても材料の生理学的影響がなく、膣炎の発生を防ぐことができる。 Furthermore, by using a nickel-titanium alloy as the shape memory alloy used for the wing part, it is easy to set the transformation end temperature Af from the martensite phase to the austenite phase around the body temperature. For example, when a nickel-titanium alloy having a nickel concentration of 56 wt% is heat-treated at 480 ° C., the transformation end temperature Af from the martensite phase to the austenite phase can be increased from 30 ° C. to 35 ° C. Furthermore, since the biocompatibility is very good, even if it is anchored in the vagina for a long time, there is no physiological effect of the material, and the occurrence of vaginitis can be prevented.

また、オーステナイト相からマルテンサイト相への変態終了温度Ｍｆが0℃から25℃にあり、且つマルテンサイト相からオーステナイト相への変態終了温度Ａｆが30℃から35℃にあれば、前記家畜用膣内留置装置の膣内への挿入作業が格段に向上し、挿入時に膣壁を傷つけるようなことを防止しつつ、上述と同じ効果を得ることが出来る。つまり、30℃から35℃以上の温度において前記翼部が前記筒状容器の長手方向軸線から外方へ延在するように形状記憶させた前記家畜用膣内留置留置装置を、膣道に挿入する前に室温または室温以下の温度(0℃から25℃)に調温してから膣道を通過可能に前記翼部を曲げたたむと、翼部は塑性変形してその状態を維持することが可能で、その状態の家畜用膣内留置装置が膣内に挿入された後は、家畜の体温により翼部が30℃から35℃以上になるため前記筒状容器の長手方向軸線から外方へ延在するように翼部が展開し、且つ超弾性状態になり膣内に安定して係留される。 If the transformation end temperature M f from the austenite phase to the martensite phase is from 0 ° C. to 25 ° C. and the transformation end temperature A f from the martensite phase to the austenite phase is from 30 ° C. to 35 ° C., The vaginal indwelling device for insertion into the vagina is remarkably improved, and the same effect as described above can be obtained while preventing the vagina wall from being damaged during insertion. In other words, the veterinary indwelling device for domestic animals, in which the shape of the wings extends outward from the longitudinal axis of the cylindrical container at a temperature of 30 ° C. to 35 ° C. or more, is inserted into the vaginal tract If the wing is bent to allow passage through the vagina after adjusting to room temperature or a temperature below room temperature (0 ° C to 25 ° C), the wing may plastically deform and maintain its state. After the veterinary indwelling device for livestock in that state is inserted into the vagina, the wings will rise from 30 ° C to 35 ° C or more due to the body temperature of the livestock, so that it will be outward from the longitudinal axis of the cylindrical container. The wings expand so as to extend, become superelastic, and are stably anchored in the vagina.

この発明の家畜用膣内留置装置はおいては、前記筒状容器内部に装着されて前記家畜の体外の信号受信装置と通信する送信装置と、前記筒状容器内または筒状容器外の前記膣内に配置されて所定種類の状態を検出し、その検出結果を前記送信装置に送る検出部とを具えることにより、膣内留置式センサとして利用できる。
これにより上記膣内膣内留置装置は膣道内に配置されて延在し、送信装置は、上記筒状容器内に装着されて、家畜の体外の信号受信装置と通信し、そして検出部は、筒状容器内または筒状容器外の膣内に配置されて、例えば膣内の温度や、膣内の体液の酸性度（ｐＨ）や、その体液の電導度等の所定種類の状態を検出し、その検出結果を送信装置に送る。
１ヶ月以上の長期間にわたり家畜の健康を害することなく膣内の生体情報を検出し、例えば図８に示されるようなシステムで検出結果をモニタすることが出来るため、適切な飼料管理、疾病の早期発見、発情検知、分娩予測といった管理が可能である。 In the veterinary indwelling apparatus for livestock of the present invention, a transmitting apparatus that is mounted inside the cylindrical container and communicates with a signal receiving apparatus outside the livestock body, and the vagina inside or outside the cylindrical container. It is possible to use it as a vaginal indwelling sensor by including a detection unit that is arranged inside and detects a predetermined type of state and sends the detection result to the transmission device.
Thereby, the intravaginal indwelling device is disposed and extends in the vaginal tract, the transmitting device is mounted in the cylindrical container, communicates with the signal receiving device outside the livestock body, and the detection unit is It is placed in the vagina inside or outside the cylindrical container to detect certain types of conditions such as the temperature in the vagina, the acidity (pH) of body fluid in the vagina, and the electrical conductivity of the body fluid. The detection result is sent to the transmission device.
For example, it is possible to detect biological information in the vagina without harming the health of livestock over a long period of one month or longer, and monitor the detection result with a system such as shown in FIG. Management such as early detection, estrus detection, and delivery prediction is possible.

さらに、この発明においては、翼部が前記所定種類の状態を検出しその検出結果を前記信号送信装置に送る検出部を導電性電極として膣壁又は膣内粘液と接触させることができ、この場合、膣壁や膣内体液との接触状態が安定するため、膣内の温度や、膣内の体液の酸性度（ｐＨ）や、その体液の導電度等の所定種類の状態データを安定して検出することができる。   Furthermore, in the present invention, the wing part can contact the vagina wall or the mucous fluid in the vagina as a conductive electrode that detects the predetermined type of state and sends the detection result to the signal transmission device. Because the contact state with the vagina wall and the body fluid in the vagina is stable, the condition data of a predetermined type such as the temperature in the vagina, the acidity (pH) of the body fluid in the vagina, the conductivity of the body fluid is stabilized. Can be detected.

また、前記筒状容器に生理学的に効果のある薬剤を含浸および／または貼付させることができる。例えば黄体ホルモン剤が筒状容器に含浸されている膣内留置装置を膣内に留置すると、家畜の発情を同期化する上で有用である。例えばCIDR(登録商標、米国、Pharmacia Animal Health社)のような現在入手しうる膣内挿入装置はその使用により膣炎や膣粘液の白濁化および漏出が認められるが、本発明の膣内留置装置の使用により、装置の膣内留置に起因する膣炎の発生を防ぐことが出来る。   Further, the cylindrical container can be impregnated and / or stuck with a physiologically effective drug. For example, indwelling an intravaginal indwelling device in which a luteinizing hormone agent is impregnated in a cylindrical container is useful for synchronizing the estrus of livestock. For example, currently available intravaginal insertion devices such as CIDR (registered trademark, Pharmacia Animal Health, USA) can be used for vaginitis and vaginal mucus turbidity and leakage. Can prevent the occurrence of vaginitis due to the indwelling of the device in the vagina.

この第1実施例の牛用膣内留置装置によれば、片側4枚のステンレスワイヤ製の翼部1が環状形状となることで膣内に係留されるので、膣内を傷つけることがなく、膣外方向に当該留置装置が排出されようとする力に対して翼部の弾性力により抵抗するため、膣内からの当該留置装置の不測の脱落を防止するのに充分な大きな係留力を得ることができる。
翼部1の線径または枚数または大きさを調節することにより、一種類のみあるいは僅かな種類で、牛の個体差に応じて常に大きな係留力を得ることができる。
さらにこの第1実施例の牛用膣内留置装置によれば、翼部1はステンレスワイヤからなるため、膣内の体液の自然排出を物理的に遮ることなく、膣内体液の滞留に起因した腱炎の発生も防止できる。 According to the cow intravaginal indwelling device of the first embodiment, the wings 1 made of four stainless steel wires on one side are anchored in the vagina by forming an annular shape, so that the inside of the vagina is not damaged, Because the elastic force of the wings resists the force that the indwelling device is to be discharged in the outward direction of the vagina, a large mooring force sufficient to prevent the indwelling device from accidentally falling out of the vagina is obtained. be able to.
By adjusting the wire diameter, number of sheets, or size of the wing portion 1, a large mooring force can always be obtained with only one type or a few types according to individual differences in cattle.
Further, according to the cow intravaginal indwelling device of the first embodiment, since the wing part 1 is made of stainless steel, it is caused by the stay of the body fluid in the vagina without physically blocking the natural discharge of the body fluid in the vagina. The occurrence of tendonitis can also be prevented.

図２（a）、（b）に示す第2実施例の牛用膣内留置装置は、筒状容器2内に配置されて上記膣内の所定種類の状態を検出し、その検出結果の電気信号を信号送信装置4に送る前記状態検出部5ｃの代わりに、膣内に配置されて温度や体液の酸性度（pH）や導電度等の、前記状態検出部5ｃと異なるかまたは同一の所定種類の状態を検出し、その検出結果を筒状容器2内の信号送信装置4に送る外部状態検出部5aを具えている。
ここで、外部検出部5aを筒状容器2内の信号送信装置4に繋ぐリード線5bは、翼部1が筒状容器2の長手方向軸線から外方へ延在するよう配置した形状の状態でも外部検出部5aが膣内の底壁に接触できる程度の長さを有しており、また外部検出部5aは牛の姿勢に拘らず自重でぶら下がって膣内の子宮前庭部等の体液に接触できる程度の重さを有している。
かかる第2実施例の牛用膣内留置装置によれば、先の第1実施例と同様の作用効果が得られるのに加えて、外部状態検出部5aが膣内の状態を直接的に検出するので、その状態の変化をより高感度に検出することができる。 2 (a) and 2 (b) is a bovine vaginal indwelling device according to a second embodiment, which is disposed in a cylindrical container 2 to detect a predetermined type of condition in the vagina, and the electrical result of the detection result. Instead of the state detection unit 5c that sends a signal to the signal transmission device 4, a predetermined or different from or identical to the state detection unit 5c, such as temperature, body fluid acidity (pH), conductivity, etc., disposed in the vagina An external state detection unit 5a that detects the state of the type and sends the detection result to the signal transmission device 4 in the cylindrical container 2 is provided.
Here, the lead wire 5b that connects the external detection unit 5a to the signal transmission device 4 in the cylindrical container 2 is in a state in which the wing part 1 is arranged so as to extend outward from the longitudinal axis of the cylindrical container 2 However, the external detector 5a has such a length that it can contact the bottom wall of the vagina, and the external detector 5a hangs under its own weight regardless of the posture of the cow, and is applied to body fluids such as the vestibule of the vagina. It has enough weight to touch.
According to the cow intravaginal indwelling device of the second embodiment, in addition to obtaining the same effects as those of the first embodiment, the external state detection unit 5a directly detects the state in the vagina. Therefore, the change in the state can be detected with higher sensitivity.

図３（a）、（b）に示す第３実施例の牛用膣内留置装置は、筒状容器2内に配置されて上記膣内の所定種類の状態を検出し、その検出結果の電気信号を信号送信装置4に送る状態検出部5ｃと、膣内に配置されて温度や体液の酸性度（pH）や導電度等の、状態検出部5ｃと異なるかまたは同一の所定種類の状態を検出し、その検出結果を筒状容器2内の信号送信装置4に送る外部状態検出部5aとの両方を具えている。
ここでも、外部状態検出部5aを筒状容器2内の信号送信装置4に繋ぐリード線5bは、翼部1が筒状容器2の長手方向軸線から外方へ延在するよう配置した形状の状態でも外部状態検出部5aが膣内の底壁に接触できる程度の長さを有しており、また外部状態検出部5aは牛の姿勢に拘らず自重でぶら下がって膣内の子宮前庭部等の体液に接触できる程度の重さを有している。
かかる第３実施例の牛用膣内留置装置によれば、先の第1実施例と同様の作用効果が得られるのに加えて、第２実施例の作用効果である外部状態検出部5aが膣内の状態を直接的に検出するので、両者によりその状態の変化をより高感度に検出することができるなどの相乗の効果が得られる。 A cow intravaginal indwelling device according to a third embodiment shown in FIGS. 3 (a) and 3 (b) is arranged in a cylindrical container 2 to detect a predetermined kind of state in the vagina, and the electrical result of the detection result. A state detection unit 5c that sends a signal to the signal transmission device 4, and a predetermined type of state that is different from or identical to the state detection unit 5c, such as temperature, acidity (pH), conductivity, etc. It includes both an external state detection unit 5a that detects and sends the detection result to the signal transmission device 4 in the cylindrical container 2.
Here again, the lead wire 5b connecting the external state detection unit 5a to the signal transmission device 4 in the cylindrical container 2 has a shape in which the wing part 1 is arranged to extend outward from the longitudinal axis of the cylindrical container 2. The external state detection unit 5a has such a length that it can contact the bottom wall in the vagina even in the state, and the external state detection unit 5a hangs under its own weight regardless of the cow's posture, etc. It is heavy enough to come into contact with body fluids.
According to the vaginal indwelling apparatus for cattle according to the third embodiment, in addition to obtaining the same operational effects as those of the first embodiment, the external state detection unit 5a which is the operational effects of the second embodiment is provided. Since the state in the vagina is directly detected, a synergistic effect is obtained such that the change in the state can be detected with higher sensitivity.

さらに他の実施例の牛用膣内留置装置においては、前記翼部1をニッケルーチタン合金製で超弾性特性を示す形状記憶合金とした。かかる実施例の牛用膣内留置装置によれば、図５に示されるように翼部1は前記筒状容器の長手方向軸線から各翼の遠位端に対する角度が0℃から180℃の範囲で弾性的に変形可能であり、折り曲げに対抗することができる。また翼部1の生体適合性と超弾性がステンレスワイヤより優れるため、長期間に渡る膣炎の防止効果がより高く、塑性変形をおこしにくいため、繰り返し使用することが出来る。
さらに上記の実施例において、翼部を形成している金属製ワイヤを図９に示されるように一本のワイヤで構成することもできる。 In still another embodiment of the bovine vaginal indwelling apparatus, the wing part 1 is made of a nickel-titanium alloy and made of a shape memory alloy exhibiting superelastic characteristics. According to the intravaginal indwelling apparatus for cows of this embodiment, as shown in FIG. 5, the wing part 1 has an angle with respect to the distal end of each wing from the longitudinal axis of the cylindrical container in the range of 0 ° C. to 180 ° C. It is elastically deformable and can resist bending. Further, since the biocompatibility and superelasticity of the wing part 1 are superior to those of stainless steel wires, the effect of preventing vaginitis over a long period of time is higher, and plastic deformation is less likely to occur, so that it can be used repeatedly.
Further, in the above-described embodiment, the metal wire forming the wing portion can be constituted by a single wire as shown in FIG.

図６は、さらにこの発明の他の実施例の牛用膣内留置装置の外観を示す斜視図である。この実施例の牛用膣内留置装置においては、翼部7が導電性電極として膣壁又は膣内粘液と接触して、膣内の温度や体液の酸性度（pH）や導電度等の所定種類の状態を検出し、その検出結果を前記信号送信装置4に送る外部状態検出部となる。一実施例では、最も遠方に位置する翼部7の電極対（図６におけるA−H）間で導電度を検出した。この検出方法により膣内の非局所的な状態を検知することが出来る。さらに他の実施例では、膣口付近に位置する翼部7の電極対（図６におけるA−D）と膣の奥に位置する翼部7の電極対（図６におけるF−G）で同一の状態（導電度）を検出した。この検出方法により膣内のデータ分布を把握することが可能であり、得られたデータを平均化することでデータを丸めることも出来る。このデータの丸め方は単一データの移動平均処理とはことなり、発情時に見られる急激な状態変化をより確実に捕らえることが出来る。
この実施例の牛用膣内留置装置によれば、先に述べた実施例と同様の作用効果に加えて、膣壁や膣内粘液と接触良好な翼部1が膣内の状態を直接的に検出するので、膣内の状態の変化をより高感度で、精確に安定して検出することができる。 FIG. 6 is a perspective view showing the external appearance of a bovine intravaginal indwelling device according to another embodiment of the present invention. In the cow's intravaginal indwelling device of this embodiment, the wing portion 7 is in contact with the vagina wall or the mucous fluid in the vagina as a conductive electrode, and the vagina temperature, body fluid acidity (pH), electrical conductivity, etc. It becomes an external state detection unit that detects the state of the type and sends the detection result to the signal transmission device 4. In one example, the conductivity was detected between the electrode pair (AH in FIG. 6) of the wing portion 7 located farthest away. By this detection method, a non-local state in the vagina can be detected. In still another embodiment, the electrode pair of the wing part 7 (A-D in FIG. 6) located in the vicinity of the vaginal opening and the electrode pair of the wing part 7 located in the back of the vagina (F-G in FIG. 6) are the same. The state (conductivity) was detected. By this detection method, it is possible to grasp the data distribution in the vagina, and the data can be rounded by averaging the obtained data. This method of rounding data is different from the moving average processing of single data, and it is possible to capture a sudden state change seen at the time of estrus more reliably.
According to the cow's intravaginal indwelling device of this embodiment, in addition to the same effects as the embodiments described above, the wing portion 1 having good contact with the vagina wall and the mucus in the vagina directly controls the state in the vagina. Therefore, it is possible to detect the change in the state of the vagina with high sensitivity and accurately and stably.

また上述の実施例に限らず、翼部7の枚数や回路に応じて、膣内の単一の状態を検出してもよいし、膣内の複数の状態を検出しても良い。   In addition to the above-described embodiment, a single state in the vagina may be detected or a plurality of states in the vagina may be detected according to the number of wing parts 7 and the circuit.

図７に示されるように本発明の家畜用膣内留置装置は牛の膣内に留置される。   As shown in FIG. 7, the intravaginal indwelling apparatus for livestock of the present invention is placed in the vagina of a cow.

牛にプロゲステロン（黄体ホルモン）を持続的に投与すると、下垂体前葉からのLH（黄体形成ホルモン）とFSH〈卵胞刺激ホルモン〉の放出が抑制される。卵胞の発育は抑制され、発育中の卵胞は退行し、発情周期が停止する。投与を中止すると、下垂体前葉からのLHとFSHの放出抑制が解除され、その結果、卵胞の発育が再開される。そして、発情が発現する。牛に黄体ホルモンを持続的に投与する薬剤として、CIDR（膣内に挿入するもの）などがある。
他の実施例ではナイロン製の筒状容器にプロゲステロン（黄体ホルモン）1.9gを含浸させたシリコンエラストマーをコーティングし、翼部として超弾性特性を示すニッケルーチタン合金製の形状記憶合金を用いた膣内留置装置を牛に15日間留置した後に取り出した。
30頭の牛に実施したが、全頭が膣内留置装置を除去後2〜4日以内に発情が発現した。
また、試験期間中、該膣内留置装置の脱落はなく、膣炎の発生も観察されなかった。この様に発情を同期させる目的で該膣内留置装置を用いる場合、プロゲステロン量は、血中プロゲステロン濃度を下垂体前葉からのLHとFSHの放出を抑制するのに十分な量、すなわち2ng/ml以上に保つ量であればよい。 Progesterone (lutein hormone) is continuously administered to cattle, and the release of LH (luteinizing hormone) and FSH (follicle stimulating hormone) from the anterior pituitary gland is suppressed. The follicular development is suppressed, the developing follicle regresses, and the estrous cycle stops. When the administration is stopped, the suppression of the release of LH and FSH from the anterior pituitary is released, and as a result, follicular development is resumed. And estrus develops. Examples of drugs that continuously administer luteinizing hormone to cattle include CIDR (inserted into the vagina).
In another embodiment, a nylon tubular container is coated with a silicone elastomer impregnated with 1.9 g of progesterone (lutein hormone), and a vagina using a shape memory alloy made of nickel-titanium alloy showing superelastic characteristics as a wing part The indwelling device was left in the cow for 15 days and then removed.
In 30 cows, estrus developed within 2-4 days after removal of the vaginal indwelling device.
Further, during the test period, the indwelling device in the vagina was not dropped, and the occurrence of vaginitis was not observed. When the vaginal indwelling device is used for the purpose of synchronizing estrus in this way, the amount of progesterone is sufficient to suppress the release of LH and FSH from the anterior pituitary, ie, 2 ng / ml. What is necessary is just the quantity kept above.

この実施例に限定されることなく、生理学的に効果のある薬剤は筒状容器に直接含浸されていてもよく、医薬用カプセルに充填された薬剤を筒状容器に貼り付けてもよい。   Without being limited to this embodiment, the physiologically effective drug may be directly impregnated into the cylindrical container, or the drug filled in the pharmaceutical capsule may be attached to the cylindrical container.

以上、実施例に基づき説明したが、この発明は上述の構成に限定されるものでなく、例えば筒状容器2の片端に配置される翼部1の枚数は2枚でも良いが、家畜の膣壁と筒状容器1との接触を減らす効果を得るためには3枚以上が好ましい。   Although the present invention has been described based on the embodiments, the present invention is not limited to the above-described configuration. For example, the number of the wing portions 1 arranged at one end of the cylindrical container 2 may be two, but the vagina of the domestic animal In order to obtain the effect of reducing the contact between the wall and the cylindrical container 1, three or more are preferable.

本発明の家畜用膣内留置装置の翼部は超弾性による変形回復力により、適切な係留力を得ることができ、過度に膣壁を刺激することがなく、長期に渡り係留しても膣炎の発生を防ぐことが出来る。また塑性変形をおこすことがないため、繰り返し使用することが出来るなど優れた効果があり、家畜用膣内留置装置として、この分野での高い利用が可能となる。   The wing part of the veterinary indwelling apparatus for livestock of the present invention can obtain an appropriate mooring force due to the deformation recovery force due to superelasticity, does not excessively irritate the vagina wall, The occurrence of flame can be prevented. In addition, since plastic deformation does not occur, there is an excellent effect that it can be used repeatedly, and it can be used in this field as a vaginal indwelling apparatus for livestock.
