The invention relates to a modular irradiation device having a main module and at least one support cassette, the support cassette being insertable into a receptacle of the main module. The support cassette has at least one pump, and the main module has at least one pump actuator, these being arranged such that the pump is actuatable with the pump actuator when the support cassette is inserted into the receptacle of the main module.

A breath actuated metered dose inhaler including a housing, a canister and a trigger mechanism. The trigger mechanism is activated by the inhalation of air which comprises of a diaphragm. The central rigid disk of the diaphragm is provided with the interlocking means to firmly secure and bound the peripheral flexible polymer ring with the central rigid disc. The mechanical interlock between a central rigid disk and a peripheral flexible polymer ring on the diaphragm prevent peripheral flexible polymer ring from being peeled off from the central rigid disc while the vacuum is being retained prior to inhalation.

The present disclosure relates to a device to provide a discomfort-reducing sensations to an area in preparation for injection or other needle puncture. The system includes a vibration source, as well as an electrical stimulation source. These two operate in combination to cause a numbing sensation to the patient, at which point a needle can puncture the skin without causing pain, discomfort, flinching, and mental distress.

A drug infusion device with security base includes a reservoir, used for accommodating the drug to be infused, provided with a piston and a screw; a driving wheel, connected with the screw, driving the screw to push the piston forward by rotation; an infusion needle unit, including an infusion needle and a infusion needle holder, the infusion needle holder used to fixedly place the infusion needle; an adhesive patch, for attaching the infusion device module to the skin surface; and a security base, arranged on the bottom of the adhesive patch, provided with an infusion needle accommodating part, for accommodating the infusion needle when the infusion device is priming. The infusion needle accommodating part can accommodate the infusion needle protruding from the adhesive patch, preventing the infusion needle from stabbing the user.

A sensor patch, system, and method for detecting a fluid leaked from a target site of a subject are provided. The sensor patch (100) includes a first detecting unit (127), a second detecting unit (128), and a patch body (110). The first detecting unit (127) includes a first pair of sensors (120A) respectively having a first end (121A) configured to be placed approximating the target site, while the second detecting unit (128) includes a second pair of sensors (120B) respectively having a first end (121B) configured to be placed away from the target site. Each sensor includes a conductive wire (125) and an insulating sheath (126) encapsulating the conductive wire (125) in a manner that a portion of the first end (121A, 121B) of the conductive wire (125) is exposed yet without directly contacting the subject's skin. The patch body (110) has an adhesive surface (104) for securing the first and second detecting units (127, 128) to the subject. The sensor patch enhances the detection specificity.
