Abstract: A laryngeal-mask construction comprises a tube body, provided with an external expanding portion at its one end, wherein said external expanding portion has a shape like a cap with indentations at its front sides and is provided with a stud on its front end, while on the lower other end of said tube body, an extending tube end with a circular plate is formed by extending therefrom; a hollow annular resilient support, which is also supported by a horse-shoe shape fenestrated plate bridging between the said hollow annular resilient support and the groove in the extending tube provided for joining around said external expanding portion; a pliant elastomeric beret, being sticky and tensile, and used for enclosing said external expanding portion and said hollow annular resilient support to form integrally a laryngeal-mask construction that, after inserting into the oral cavity of a patient, can make the distal airway opening closer to the larynx of the patient for achieving an effective seal and lessening the risk

Abstract: The present invention provides a non-invasive apparatus for continuously measuring a plurality of physiological variables from a user's ear. The non-invasive apparatus includes a body, a temperature detector positioned on the body, a plastic housing encapsulating the body, a light emitting device for emitting a light beam to a tragus of the user's ear, and a light receiver for receiving the light beam penetrating through the tragus. The temperature detector can measure the user's body temperature from a tympanic membrane. The light emitting device incorporating the light receiver can measure the blood oxygen saturation of the user by detecting the energy loss of the light beam due to the penetration through the tragus. The plastic housing includes an awl-shaped portion capable of inserting into an auditory meatus of the user's ear and a protrusion capable of engaging with a triangular fossa of the user's ear.

Abstract: A safe cover device for the needle of a syringe comprising an external sleeve, a syringe clamp, a needle cap and an annular collar, of which the syringe clamp and the annular collar are combined with each other on a syringe, and the external sleeve is slipped over the syringe to completely accommodate the needle. So that when the needle cap covers the needle, stabbing of the needle and infection of germs can be avoided; thereby, the medical staff using the syringe can be protected. The device can be easily mounted and can be repeatedly used to reduce cost and get an environmental conservative effect.

Abstract: A protecting cap structure for the needle of a syringe, wherein, the structure is provided with a protecting sleeve having a receiving space for receiving a needle. The protecting sleeve is comprised of a foldable cover and a cylindrical extendible member connected with each other; the cylindrical extendible member is a hollow cylinder, the shank of the cylindrical extendible member has a compression portion; a pair of foldable portions are provided in neighboring to the compression portion; the foldable cover is in the shape of a semi-cylinder, one end of the foldable cover is connected with the cylindrical extendible member, in order that when the cover is folded to close, it cooperates with the cylindrical extendible member to envelop and fast envelop the needle to prevent the needle from accident stabbing.

Abstract: A needle extracting and recovering device, the device is provided on the top of a case thereof with a needle insertion hole for insertion of a needle holder of a syringe with a needle to be extracted, an inclined rotation axle mechanism including a rotating knob is provided below the needle insertion hole, the rotation axle mechanism is provided on one lateral side thereof with a slit for inserting of the needle, the needle is extracted from the needle holder by rotating the rotating knob to rotate the rotation axle mechanism.

Abstract: An auxiliary device for placing a larynx cover for anesthetization, it comprises a handle, a fixing sleeve, a pushing rod and a soft sleeve. The pushing rod is a flexible and elongate metallic rod, has on an end thereof the soft sleeve, and has on its front end a forked opening and on its bottom a bottom poker; the other end of the pushing rod has a turning portion. When the handle are connected with the pushing rod, the flexible pushing rod is extended into an air inlet pipe of the larynx cover to abut against the bottom of the larynx cover and push it forwardly by means of the bottom poker, so that the forked opening of the soft sleeve abuts on a protrusion on an annular rubber pipe in the larynx cover. The handle and the air inlet pipe are firmly combined by the fixing sleeve, the larynx cover will not be departed from the auxiliary device; and the larynx cover can be in an arciform shape without an opening, it can fit the curvature of the throat and will not poke the root of a tong of a patient.

Abstract: A Half-disposable syringe barrel including a barrel syringe and a cap member as two stages. A plunger is fitted in the syringe barrel. An emulsion ring is disposed in the cap member. The emulsion ring is formed with a membrane and is made of highly flexible material. A lubricant is overlaid on the emulsion ring and the membrane thereof. The cap member is fitted with the front end of the syringe barrel. When pulling the plunger backward to suck a medicine, the highly flexible membrane of the emulsion ring is extended and sucked to attach to the wall of the syringe barrel. Therefore, the medicine is enclosed by the emulsion ring and the membrane and isolated from the wall of the syringe barrel. Therefore, the syringe barrel and the plunger are not contaminated by the medicine and the flowing back blood. After the cap member is removed, the syringe barrel can be recovered for reuse.

Abstract: A backflow proof structure for a syringe comprising a central cylinder portion and two blocks positioned in a protruding end of the syringe, on the bottom of the cylinder portion is a flared portion and on the top thereof is a tip, the outer space of the tip is filled with a piece of crystallized syrup to separate a crown cap covering the top of the tip from the cylinder portion; when the cylinder portion is placed in the protruding end, and a silicone cube is placed there-beneath, an irregular-shaped stopper is placed to closely contact the bottom of the protruding end to push the crown cap on the top of the cylinder portion out of the protruding end.
