A device for the needle-free injection of a fluid into an animal can include a contact device including a shaped contact surface that is shaped in conformity with a body part of the animal to which the injection is to be administered. Also included is a first injector including a front dispensing end which, during the needle-free injection, extends through a first passage opening in the shaped contact surface and protrudes in relation to the shaped contact surface in a region adjacent to the first passage opening, a first measuring device which outputs at least one first measuring signal in order to detect contact of the animal with the front dispensing end of the first injector, and a control unit which activates a needle-free injection via the first injector on the basis of the at least one first measuring signal.

A therapeutic pressure strap for a mammal (animal or human). The strap comprises a flat laminated material with a textured elastic side and hook-and-loop second side, as well as a front end comprising a section of a complementary hook-and-loop material that can bind to the second side. The strap is configured so that when it is wound around the mammal's chest or trunk, the textured side resists slippage against the mammal's skin or fur, and the complementary material binds to the second side, producing a snug but reversible fit. The strap can be used to “swaddle” upset mammals and calm them without risk of overheating or causing panic due to overly restricting movement.

The present disclosure relates to airway devices. It is applicable to supraglottic devices including laryngeal airway devices and to their methods of manufacture. The present disclosure is particularly applicable to laryngeal airway devices for human and veterinary use. The device includes an airway tube having a distal end and a proximal end, the distal end of the airway tube is provided with a pre-formed and non-inflatable peri-pharyngeal bowl. The peri-pharyngeal bowl includes a posterior bowl portion having a back dorsal portion and a side wall extending around and depending from the periphery of the back dorsal portion to define an internal space, and further includes a resiliently deformable flange extending laterally from the side wall of the back dorsal portion which defines an extended internal space, the resiliently deformable flange has inner and outer surfaces that extend to a circumferential edge.

Injection systems and methods of using the same are described herein. Each injection system may include one, two, or more needles, with each needle being configured to move needle between an injection position and a retracted position to deliver an inoculant. The injection needles may rotate about a carriage axis that extends through the injection axis along which each needle moves when moving between their injection and retracted positions. The injection needles in systems that include two or more injection needles may be advanced from the retracted position to the injection position at the same or different times.

Provided in embodiments of the disclosure is a medical alarm system, including an anesthesia device, a weigher and a waste gas adsorption canister, wherein the waste gas adsorption canister is connected to the anesthesia device; the anesthesia device is in mutual communication with the weigher; the anesthesia device is configured with a first alarm apparatus thereon, wherein the anesthesia device is configured to release an anesthetic gas and discharge a waste anesthetic gas; the waste gas adsorption canister is configured to adsorb the waste anesthetic gas; the weigher is configured to acquire weight data of the waste gas adsorption canister by weighing in real time and transmit the weight data to the anesthesia device; the anesthesia device is configured to determine whether to trigger an alarm based on the weight data and at least one preset alarm threshold, and output at least one alarm prompt of sound, flashing light and an interface prompt by the first alarm apparatus upon determining to trigger an alarm, wherein the at least one preset alarm threshold is a data criterion for an adsorption capacity abnormality of the waste gas adsorption canister or a data abnormality of the weigher. The intelligence and safety of the medical alarm system can be improved by the embodiments of the disclosure.

A drug delivery apparatus including a barrel to contain a substance, a piston slidable in the barrel, a supply circuit to provide input currents, an antenna affixed along the barrel to receive the input current, generate inductance with the piston, and provide output currents commensurate with a position of the piston along the piston course, and processing circuitry configured to receive the output currents, and determine a quantity of the substance inside the barrel based on the output currents.

Methods are provided for acute treatment of agitation, including agitation in patients with schizophrenia or bipolar disorder, comprising administering to a subject with agitation an effective dose of a dry pharmaceutical composition comprising olanzapine, wherein the dose is administered by an intranasal delivery device that provides, following intranasal administration, (a) a mean peak plasma olanzapine concentration (C.sub.max) of at least 30 ng/mL, with (b) a mean time to C.sub.max (T.sub.max) of olanzapine of less than 0.5 hours. Dry pharmaceutical compositions and devices suitable for intranasal delivery of olanzapine are provided.

A method of determining a cumulative presence of suction in a patient having an implanted blood pump including determining whether at least one suction event occurred during a predetermined time interval for a predetermined number of time intervals and determining the cumulative presence of suction by dividing a sum of a number of predetermined time intervals in which at least one suction event occurred by the predetermined number of time intervals.

A needle guard for protecting a human or animal from accidental contact with a needle connected to said needle guard is disclosed. The needle guard comprises a mounting base for the needle, a hinge structure connecting the mounting base to a needle shield, and a needle shield hinge adjacent to the hinge structure and needle shield. The hinge structure is adapted to pivot the needle shield relative to the mounting base from an open position in which the needle shield is separated from the needle to a closed position in which the needle shield encloses the needle. The needle shield hinge is adapted to pivot the needle shield relative to the hinge structure. A method of manufacturing the needle guard is also disclosed.

A system for actuating a volume and/or pressure-controlled manual ventilator including a manual ventilator, a storage case, and an actuating mechanism. The manual ventilator includes a compressible body, an output one-way valve at an output end, and an input one-way valve at an input end. The storage case includes an inner housing surface configured to accommodate the manual ventilator. The actuating mechanism includes a power unit mechanically coupled to a linear rod mechanism and one or more applicator pads mechanically coupled to the linear rod mechanism and proximal to the compressible body. The linear rod mechanism is configured to convert a rotating motion of the power unit into an axial movement of the linear rod mechanism. The actuating mechanism is configured to apply pressure to the compressible body of the manual ventilator via the one or more applicator pads such that a volume of the compressible body is deflated.
