Abstract: The present disclosure discloses a radiation treatment device and pertains to the field of medical appliance technologies. The radiation treatment device includes a radiotherapy unit and an imaging unit. The radiotherapy unit is configured to emit a treatment beam to a to-be-treated region in a patient, wherein the to-be-treated region in the patient is located outside the radiotherapy unit. The imaging unit is arranged adjacent to the radiotherapy unit and is configured to emit an imaging beam to the to-be-treated region in the patient. Without moving the to-be-treated region in a patient, the radiotherapy unit may emit the treatment beam to the to-be-treated region in the patient according to the treatment plan worked out to execute the radiation treatment, such that the accuracy of the radiation treatment is improved.

Abstract: The present disclosure discloses a radiation treatment plan generation method, which is applied to a therapeutic equipment comprising at least two therapeutic heads. The method comprises the steps of: acquiring images of an area of the patient with a tumor; determining a treatment target region including the tumor as a region for being irradiated with a radiation beam upon radiotherapy; obtaining a prescription dose of the treatment target, wherein the prescription dose comprises a parameter of prescription dose value that is a magnitude of a dose received by the tumor; and determining a therapeutic head, a therapeutic approach and a therapeutic drive approach suitable for irradiating the target region, based on the therapeutic target region and the prescription dose thereof.

Abstract: A knife handle assembly adapted for attachment to a knife blade, including an elongated handle having a cavity formed therein and a pliable section positioned adjacent the cavity; an elongated rod extending along a longitudinal axis and into the cavity; a user engageable member attached to the rod on the exterior of said handle and adapted to permit selective rotation of the rod about its longitudinal axis; and a first cam positioned within the cavity and in abutting relation to the pliable section and engaged with the rod, wherein rotation of the rod about its longitudinal axis translates to movement of the first cam into said pliable section an amount corresponding to the degree of rotation.

Abstract: A new and improved cutting instrument is provided having an enhanced coating. The coating includes titanium, chromium, nitrogen and carbon elements and provides increased wear resistance. The coating can be applied to a variety of metal and non-metallic substrates, which include scissors and knife blades.

Abstract: Disclosed is a fish dehooking device for permitting a fisherman to separate a fish from a fishing hook and line. The dehooking device includes a pair of pivotally connected handles one of which is coupled to a dehooking assembly such that its pivotal movement is translated into linear movement of the dehooking assembly. Positioning of a line/hook against the dehooking assembly followed by retraction of the dehooking assembly through the squeezing of the handles together results in the release of a fish from a hook and line.

Abstract: The present disclosure discloses a radiotherapeutic device. The radiotherapeutic device includes a gantry, a detector and a slide driving unit. The slide driving unit includes a sliding guide rail, a driving apparatus and a movable block. The detector is fixed on the movable block. The movable block drives the detector to slide along the sliding guide rail driven by the driving apparatus.

Abstract: The present invention provides a focused radiotherapy apparatus comprising: at least one source part, provided with a plurality of radioactive sources arranged thereon; at least one collimation part enclosing the source part, and comprising a plurality of collimators aligned corresponding to the radioactive sources, the radiation rays emitted by the plurality of radioactive sources passing through the collimators and then converging to a focal point for treatment.

Abstract: A requisition system for safety items such as first aid kits, blood borne pathogen kits, automatic external defibrillators, fire extinguishers, smoke detectors and carbon monoxide detectors automatically generates a list of supplies for such items. The requisition system operates on a mobile electronic device. The user or customer can efficiently undertake an inventory of the replaceable supplies for the safety items and generate a requisition for such safety items. The requisition system provides for an automatic notification alert to the user and also provides an alert notification button to initiate an inventory of replaceable supplies. A requisition of the replaceable supplies is automatically communicated to the supplier. The requisition system also automatically generates a requisition of supplies so that a first aid kit or other safety item fully complies with applicable current safety standards. The requisition system also is operable to implement an automatic replenishment of supplies.

Abstract: An anti-biofouling method which suppresses biofouling in water includes a preparation step of using a copper alloy-made anti-biofouling object member immersed in the water as a cathode electrode, and immersing and arranging an anode electrode member serving as a counter electrode of the anti-biofouling object member in the water, and a current supplying step of supplying DC current between the anti-biofouling object member and the anode electrode member.

Abstract: A fishing tackle module is provided for removable attachment to the rim of a bucket. The module includes a curved body member having a flanged leading edge adapted for engagement with the rim of a bucket, a trailing edge, and a surface that extends between the flanged leading edge and the trailing edge; a plurality of enlarged openings formed through the surface at spaced intervals; a plurality of apertures formed through the surface at spaced intervals adjacent the trailing edge; and a sheath engaged with and extending downwardly from one of the enlarged openings.

Abstract: A glue gun dispensing nozzle indicator changes color when a heater element exceeds a transition temperature. In one embodiment, the temperature indicator changes from a blue color to a red color to indicate that the temperature is sufficient so that the glue gun may dispense molten glue. Temperature dependent color pigments are applied as coatings to the indicator.
