Abstract:
The invention discloses a semen catheter improvement for artificial insemination in animals, comprising a connecting orifice disposed at the head part of flexible catheter, a more rigid cap body fitted over the connecting orifice, a covering member disposed at the inward end of cap body and propping against the head part of catheter and a drain orifice having a plug at the outward end. Using the more rigid cap body that is less prone to deformity and the covering member propping against the head part of catheter for exertion of force when operator pinches it between fingers, operator can insert the drain orifice into the insemination tube in a substantially simple, convenient, fast and accurate manner. More so, such design prevents outflow of semen caused by fingers directly pinching the flexible head part of catheter. In addition, the plug of drain orifice may be snapped off to form an open drain opening and plugged reversely back to close the drain opening. As such, the practice of artificial insemination for animals is made simple and convenient, and free of wasteful semen outflow. The device can also be used for screening of semen.
Abstract:
An artificial micro-insemination device for animals is disclosed. The device has an elastic insemination sheath amassed in compressed state between the nozzle passage and the forward portion of center orifice of catheter tube, where the rear end of the elastic insemination sheath is secured to the front part of nozzle, characterized in which the catheter tube and nozzle are inserted into the uterus of animal with the nozzle positioned posterior to the first cervical ring, and by the pressure of semen dispenser squeezing in semen from the rear end of catheter tube, the extension member of the soft elastic insemination sheath instantaneously extend outward from the front part of nozzle and extends freely along the cervical tract to reach uterus, where coupled with uterine contraction, semen fluid squeezed into the extension member of insemination sheath is expelled into the uterus or the two ducts to uterine horns via the prearranged slits on the front part of extension member. Such design not only reduces the backflow of semen, it also offers the economic benefit of using minimal semen and improves the efficiency of artificial insemination.

This invention relates to a device and method for optical nanoindentation measurement, according to which respective measurement results are obtained by having an indenter tip apply load to a fixed portion of a thin film, having an indenter tip apply load to a non-fixed portion of a thin film, and having a vibrating component transmit the dynamic properties of the vibration to the thin film. By combining the above measurement results in calculations, the Young's modulus, the Poisson's ratio, and the density of the thin film can be obtained.
Abstract:
An improved artificial insemination device with an inner catheter for animals is disclosed. The device is characterized by having a thin flexible tube and a positioning stop member installed respectively at the front end and rear end of an inner catheter that is movably inserted in the catheter tube. The thin flexible tube instantly extends forward from the front end of inner catheter when semen is squeezed into the inner catheter. Thus after the nozzle of catheter tube reaches the first cervical ring of the animal, the inner catheter only needs to extend inward a proper distance, and the semen, with the aid of squeeze force and the thin flexible tube advancing freely along the cervical tract, could be delivered to uterus smoothly, swiftly and accurately without causing trauma to the uterus. Also with the arrangement of the positioning stop member, the distance the inner catheter travels inward can be set. As the depth and location of inward extension are under proper control, the practice of artificial insemination is made simple, convenient, fast, efficient and safe for the animal.
Abstract:
An improved animal-use artificial inseminator comprised of an insemination tube with a nozzle at its front extremity into which an insemination sheath is inserted and a connector at the rear extremity of the insemination tube having a check membrane. After the insemination tube penetrates the female animal body vagina and the front end of the nozzle is nominally at the first cervical ring of the cervix, the semen bottle insertion tube is utilized to pierce the connector check membrane at the rear extremity of the insemination tube and when the semen at the insemination tube is squeezed, semen is automatically squeezed out of the insemination sheath. The soft insemination sheath proceeds along the cervix without the occurrence of friction, the front end smoothly moving forward until it reaches the position of the womb. Contractions of the womb are utilized to articulate the insemination sheath such that the contained semen is ejaculated into the two Fallopian tubes or the womb from the slits along the two sides of the front end. At the same time, after the semen bottle is pulled out, since the connector check membrane automatically opens and closes along with the contraction of the womb, not only is the semen in the insemination sheath prevented from backflow or leakage, but air is admitted for smooth and complete squeezing into the Fallopian tubes or the womb.
Abstract:
The invention discloses an improved insemination catheter for artificial insemination in animals, characterized in which a center orifice disposed at the rear end of the nozzle for connecting the catheter tube is a blind orifice, and a diversion slit is configured between and connecting the front end of center orifice and the front end of nozzle, the diversion slit being opened when semen in the catheter tube is being squeezed and closed when semen in the catheter tube is not being squeezed. As such, the front end of the nozzle would be closed when it is inserted along with the catheter tube into the vaginal orifice of female animal body during artificial insemination such that contaminants from outside the female animal body or lubricant used will not flow into the center orifice of the nozzle, thereby enhancing the safety of artificial insemination. When the animal semen is squeezed in from the rear end of catheter tube, the diversion slit will open under pressure to allow the semen to be released smoothly, rapidly and accurately into the animal uterus, thereby enhancing the efficiency of artificial insemination. Under the circumstance where the diversion slit is closed when not under pressure, semen flown into the animal uterus or amassed around the cervix will not back flow into the center orifice of nozzle or the catheter tube, thereby reducing wasteful outflow of semen and increasing the chance of conception.

Abstract:
An improved artificial insemination device for animals is disclosed. The device has an inner catheter tube inserted inside a catheter tube where the front end of the inner catheter tube is closed in arc shape and its periphery is arranged with a plurality of spray release openings with arc-shaped invagination at outer edges and an extension member that communicates with the interior. As such, when the front end of the inner catheter tube enters the uterus along the cervical tract, it will not scratch the walls of cervical tract during movement because the outer edges of the spray release openings are in arc invaginated shape. When the contraction of the uterus sucks out the animal semen inside the inner catheter tube, it works like a straw through the extension members of the spray release openings, and the semen pooled together inside the catheter could be released rapidly and smoothly into different parts of the uterus to fully enhance the efficiency and the success rate of artificial insemination.
Abstract:
The invention discloses an improved catheter for artificial insemination in animals, comprising primarily a simple improvement of the nozzle mounted at the front end of catheter. The nozzle is predefined on its peripheral surface with pores, channels, or indented texts or patterns of different shapes, which can be used to hold reagents, liquid medicine, ointment or lubricant for animals. As such, when the operator inserts the nozzle into the vagina of female animal body, the procedure achieves not only artificial insemination, but also other purposes, such as testing, experiment and treatment, thereby augmenting the usage and enhancing the efficiency of artificial insemination catheter.
