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.

Disclosed is a device for providing resuscitation or suspended state through redistribution of cardiac output to increase supply to the brain and heart for a patient. The device includes an electrically controllable redistribution component attachable to the patient to provide redistribution of the cardiac output to increase supply to the brain and heart. The redistribution component, following a predefined reaction pattern based on an electrical signal, and computer means configured to: receive a patient data which identifies physiological and/or anatomical characteristics of the patent; and provide the electrical signal for the redistribution component based on the patient data or a standard response. The device may provide mechanisms to protect the aorta and the remaining anatomy of the patient from inadvertent damage caused by the disclosed device in any usage scenario of either correct intended usage or unintended usage. Also disclosed is a method for providing resuscitation or suspended state.

A unit for supplying ink to the needles of a tattooing device includes a handling unit, in which the following can be found: a grip; a removable tip provided at one end with one or more tattooing needles; a coupling element configured to connect the grip and the tip to each other; a driver operatively associated with the grip to move the needles by imparting a reciprocating rectilinear motion to them; one or more tanks for containing the ink, operatively associated with the handling unit. The ink supply unit includes an air movement unit driven by the driver and mechanically connected to the handling unit. The air movement unit is configured to push the air moved by the driver toward the tank, the tank for containing the ink communicating with the air movement unit by a valve. Once conveyed into the tank by the valve, the air forces the ink to be dispensed from the tank onto the needles.

A manual breast pump includes: a body having a communicating part that communicates with space surrounded by a hood placed on a breast; a diaphragm that deforms to generate a negative pressure in the communicating part; and a handle for operation that approaches and separates from the body, wherein a colliding part, against which at least the handle and the body collide before directly contacting each other, is provided in at least a region of any of the handle, the body, and the diaphragm, the colliding part is integrally made of a same material as a material of a region in which the colliding part is arranged, and has a damper structure that absorbs an impulsive force or reduces propagation of the impulsive force and/or a cover structure in which the colliding part is covered via a gap so as not to be exposed to an outside.

The invention relates to the field of inhalation devices for medically active liquids. In particular, the invention relates to an inhalation device providing a particularly high pressure for nebulization. The inhalation device comprises a housing (1), a reservoir (2), a pumping unit connected (3) to a means for the delivery of mechanical energy (4) to said pumping unit (3), and a nozzle (5). The pumping unit (3) comprises a hollow cylindrical part (3A) and a piston (3B), the cylindrical part (3A) having an interior space (3C) with a defined first cross section (A1) configured to receive an upstream end portion (3B′) of said piston (3B), wherein said cylindrical part (3A) and said piston (3B) are linearly moveable relative to one another such as to form a pumping chamber having a variable volume. According to the invention, the means for the delivery of mechanical energy (4) is a pressurised gas, wherein the device comprises a pressure chamber (6) having an internal volume for holding said pressurized gas, a wall of said pressure chamber (6) being provided by a plunger (7) which is configured to perform a reciprocating linear movement such as to change the internal volume of the pressure chamber (6), wherein the plunger (7) is mechanically coupled to the piston (3B) or to the cylindrical part (3A), and wherein the plunger (7) exhibits a cross section (A2) which is larger than the cross section (A1) of the pumping chamber. Further, a method for generation of an aerosol of a medically active liquid by means of said inhalation device is disclosed.

Disclosed is an ambulatory therapeutic fluid delivery device. The device includes at least one housing connectable to a cannula, the at least one housing retaining a reservoir to hold the therapeutic fluid. The device also includes a mechanically powered pumping mechanism to cause delivery of at least some of the fluid from the reservoir, and a power-transfer mechanism to transfer manually-delivered power provided by a user to mechanically actuate the pumping mechanism.

An inhalation device including a housing, which encloses a liquid reservoir in which the liquid is stored before discharge, and an applicator head with a nebulization chamber and an applicator piece connected thereto, wherein the applicator piece is designed either as a mouthpiece, to be received in the mouth of a patient, or as an inhalation mask, to sealingly cover the mouth, the nose, or the mouth and the nose. The inhalation device furthermore has a discharge channel which connects the liquid reservoir to the applicator head. The inhalation device includes at the end of the discharge channel a nozzle plate with a large number of nozzle openings which serve to generate an inhalation mist and through which the liquid from the liquid reservoir is conveyed into the nebulization chamber.
