摘要:
A plug of an artificial insemination tube for livestock breeding includes a leading portion and a viewing portion, each having different color layers or different hardness layers, and being formed by stacking and combining different foam layers. In an artificial insemination for livestock breeding, the plug installed at the front of a sperm delivery duct is inserted into a reproductive organ of the livestock, and secretion or fluid is attached and shown on surfaces of the plug leading portion and the viewing portion with different colors to achieve the effect of detecting the physical and physiological conditions of the livestock. In addition, the leading portion is a foam layer with relatively greater hardness, density, and smoothness, so that the plug may be entered into the female livestock body more easily, and the injection hole will not be deformed easily, so as to improve the smoothness and efficiency of the artificial insemination.

An electrostatic force generator is disclosed. The electrostatic force generator includes an RF AC voltage source, a capacitive module, a resonant capacitive-inductive bridge (CIB) module, a lock-in amplifier module, and a proportional-integral-derivative (PID) controller. The resonant capacitive-inductive bridge module converts the differential capacitance to a differential signal. The differential signal from the resonant capacitive-inductive bridge module is demodulated at the RF excitation frequency by the lock-in amplifier module. The PID controller receives the output signal from the lock-in amplifier module and generates two audio frequency AC signals to generate a compensation electrostatic force and maintain the capacitance balance inside the capacitive module.

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.

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.

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.

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.
