A system and method for locating an internal device separated by a boundary from and in wireless communication with an external device. External device includes an active emitter mechanism wherein a carrier signal is modulated by a location interrogation signal thereby generating an external RF power signal during transmission to the internal device. A secondary antenna of the internal device receives the external RF power signal and induces an RF power signal therein that is converted to a DC induced voltage signal. An indication signal proportional to the intensity of the DC induced voltage signal induced in the secondary antenna is produced by the external device. The process is repeated each time the user moves the external device to a new location proximate the patient's body until a maximum DC induced voltage signal measurement is ascertained representative of a specific area in which the internal device is located.

The present invention relates to an infant feeding warming system useful to repeatedly and precisely warm breastmilk or formula for use in the NICU. The system in one form comprises a bedside unit that is attachable to an IV pole. The system may also comprise a centralized warming station with multiple chambers, wherein one chamber heats a bottle or syringe, and the remaining chambers are used for storage and / or refrigeration. The system will use a non-liquid heating system to heat feedings. A disposable liner may be used inside the chamber. The system may also contain heating algorithms that are based on a user inputting milk parameters such as volume and initial temperature.

The invention relates to a mesenchymal stem cells serum-free culture medium. The serum-free culture medium comprises a basal culture medium and an additive component, wherein the additive component comprises the following components: rhEGF, rhVEGF, rhPDGF-BB, rhFGF-b, rhTGF-beta1, human serum albumin, recombinant deferritin, a recombinant human insulin growth factor and hydrocortisone. The invention also provides an application of the mesenchymal stem cell serum-free medium. The composition is clear and stable; the instability of serum culture is eliminated, and meanwhile, all factors have thesynergistic effect, the umbilical cord mesenchymal stem cells can be efficiently amplified, the cell cycle is shortened, the proliferation is rapid, the yield of three generations of cultured cells reaches 1.5 times or more of that of serum culture, the cell consistency is good, and the biological characteristics and differentiation potential of the umbilical cord mesenchymal stem cells can be efficiently maintained due to the synergistic effect of all factors.

The invention provides a rabbit non-operative embryo transfer instrument, a method and an application thereof. The transfer instrument comprises an outer tube sleeve, an outer tube, an inner tube anda syringe. The rabbit embryo was inserted into the inner tube. Binding recipient rabbit, inserting an outer tube with an outer tube sleeve from the recipient rabbit's vagina until the tip of the outertube reaches the cervix of uterus; Pull out the outer sleeve outward so that the closed end of the outer sleeve is pierced by the tip of the outer sleeve. The outer tube is pushed so that the tip ofthe outer tube passes through the cervix, the inner tube is inserted into the tip of the outer tube, and the rabbit embryo in the inner tube is injected into the uterus with a syringe connected with the inner tube. The invention eliminates the injury and infection risk of the recipient rabbit caused by the operation, can quickly transfer the rabbit embryo into the recipient rabbit uterus, can improve the efficiency of the rabbit embryo transfer and the fetal birth rate, and is widely applied.

The invention discloses an operation robot system for performing laser resection and refrigeration on tumor tissues. The operation robot system comprises a computer system, a cryogenic system and an operation robot system, wherein an operation mechanical arm of the operation robot system is controlled by a computer mainframe to move freely; a cryogenic transmission tube of the cryogenic generator, laser fibers of a laser and a tail end image detector electrically connected with the computer mainframe extend into multiple arm sections sequentially and respectively to reach the tail end of the operation mechanical arm; cryogenic fluid is communicated with the cryogenic generator by virtue of a cryogenic solenoid valve; the tail end image detector is used for receiving relevant images and transmitting the relevant images to the computer mainframe by virtue of a data transmission line, and simultaneously, the relevant images are displayed on a display screen; the computer mainframe controls an operation robot mainframe and orders the movement, refrigeration and resection work in different directions of the operation mechanical arm; and as a doctor controls the mechanical arm to implement a whole operation in a non contact way, the tumor tissues are subjected to refrigeration and resection simultaneously, and the whole process is visualized, the precision and digitalization of the tumor resection are ensured, the risk of tumor spread is low, and the mechanical trauma is small.
