A device for straightening sutures or pre-packaged suture-needle combinations. The device has a body formed of substantially resilient material flexible enough to be penetrated by a pointed end of a needle along with a suture inserted into it or to obtain a substantial gap when a slit is cut or molded into it. The device may be held securely in a position for subsequent grasping by a user for drawing a suture through it or attached to an OEM suture packaging. A means of engagement such as adhesive provides means for temporary or permanent attachment to the suture packaging.

The present invention relates to a syringe, particularly to a small volume syringe such as a syringe suitable for ophthalmic injections.

A surgical device provides a retractor tool or rake with integral lighting. The device includes a retractor body having a rake finger at one end and a handle at its other end. A light source is embedded in the rake finger. A power unit supplies a current to the light source, and a cable interconnects the retractor body and the power unit. Sterile packaging is adapted to contain the surgical device, wherein the sterile packaging has a deactivation feature for preventing the supplying of current from the power unit to the light source while the device is stored within the sterile packaging, and wherein removal of the device from the sterile packaging results in automatically supplying the current to the light source.

A bone grinder utilizing a removable cutter head unit for maintaining the processing of bone and for substantially precluding the main body of the bone grinder from being exposed to bone tissue.

A liquid dispenser device including a valve with a valve member-forming portion for blocking and passing liquid out from the device, and a fastener edge for permanently fastening the valve relative to a container, the fastener edge including a tubular fastener wall sandwiched between an inner tubular wall and an outer tubular wall.

The present invention relates to a syringe, particularly to a small volume syringe such as a syringe suitable for ophthalmic injections.

The device makes it possible to dispense predetermined metered quantities of liquid. It includes a sealing member that can take up a liquid release position, allowing liquid to flow out of the device, and a non-return position preventing liquid from flowing back into the device. The sealing member is provided with metering means for metering out the liquid to be dispensed.

An appliance (1) for tensioning ligaments, especially articular ligaments, of a human or animal body, having at least one handle (2), the or each handle (2) being in operative engagement with, in each case, a tensioning element (3) associated therewith, and with the or each handle (2) in each case a force indicator (4), which indicates a force exerted on a or each tensioning element (3) associated with the or each handle (2) on tensioning of one or more ligaments, and a displacement indicator (5), which indicates the excursion of the tensioning element (3) in question from a reference position, and with the or each force indicator (4) and / or with the or each displacement indicator (5) there is / are associated at least one marker (7A-7H), which is arranged to be detected without contact by a measurement value ascertainment system (20) associated with the appliance (1), and also a device (20), comprising the appliance (1), for ascertaining force-displacement characteristic curves of ligaments, and also a method of ascertaining them.

It is intended to provide a process for producing a packaged drink whereby filling can be performed at room temperature without resorting to using a chemical or sterile water, the favorable taste and flavor of the content can be maintained while relieving the thermal degradation thereof, it becomes unnecessary to employ a heat-resistant container or to thermally sterilize or cool after sealing, and thus both of the equipment cost and the running cost can be largely reduced. After thermally sterilizing the content to give a definite sterilization value, it is quickly cooled to room temperature and then stored in a storage tank that has been preliminarily sterilized under such conditions as being equal to or exceeding the thermal sterilization conditions for the contents. While maintaining the storage tank under positive pressure with the use of a sterile gas, the content is fed into a filling machine that has been preliminarily sterilized under such conditions as being equal to or exceeding the thermal sterilization conditions for the contents. Thus, the liquid-feeding system ranging from the storage tank to the filling machine is made a closed liquid-feeding pathway free from the invasion of air from the outside. The drink is filled into a container having been sterilized with hot water in an environment-controlled space isolated from the outside wherein the surroundings have been thermally sterilized and washed with hot water at 65 DEG C to 100 DEG C.

User-friendly attachment mechanisms for pen needles provide improved handling and ease of use, including locking installation and removal features and sensory feedback when a needle-bearing hub is seated on a pen. Embodiments include a needle-bearing hub includes a circumferentially oriented flexible tab that engages a radially inward rib on an outer cover to assist in attaching a pen device to the pen needle.

The invention relates to a high-temperature steam biological wastewater inactivation system, and belongs to the field of high-temperature steam inactivation devices. The high-temperature steam biological wastewater inactivation system comprises a wastewater containing device, a storage tank and inactivation tanks which are connected in series through pipelines, wherein the inactivation tanks are provided with a steam discharge pipe and an inactivation drainage pipe. The high-temperature steam biological wastewater inactivation system is characterized in that: an outlet at the bottom of the storage tank is respectively communicated with the two inactivation tanks by connecting pipes; the inactivation tanks are provided with clamping sleeves; the input end of each clamping sleeve is connected with a saturated steam generator by a steam inlet pipe, and the output end of each clamping sleeve is provided with a clamping sleeve steam discharge pipe; a water inlet pipe, a connecting pipe anda steam discharge pipe of the storage tank and the steam inlet pipe, the clamping sleeve steam discharge pipe and an extinguishment drainage pipe of the inactivation tanks are provided with an air-operated valve respectively, and all air-operated valves are connected with a control device; and the control device is used for controlling the two inactivation tanks to run in a batch mode by controlling switches of the air-operated valves. The high-temperature steam biological wastewater inactivation system can realize the batch-type treatment of wastewater, is flexible in control and high in safety factors.

The invention relates to a rape chemical hybridization agent composition and uses thereof, wherein the composition (SX-1) contains active constituent of 2-[3-(4- methoxy-6- methyl-1,3,5- triazine-2-group)-3- methyl carbamido sulfonyl] methyl benzoate, aerosol, emulsifying agent, thickening agent, crumbling agent and soluble starch. The invention also relates to the method of use and application in rape chemical hybridization of the composition.

A method and apparatus for sterilizing containers, such as cans, bottles, or similar containers. The method involves relatively moving a container and an elongated electron radiation treatment member with respect to one another, such that the treatment member is located in the container. The treatment member is used to treat the entire inside surface of the container with identical or essentially identical radiation power, and then is removed from the container.
