Для этого осуществляют проведение иглы через просвет наружного слухового прохода и введение раствора в виде инъекций. При этом проводят иглу через просвет наружного слухового прохода до его медиальной части. Введение иглы начинают по направлению от переднего меатотимпанального угла к заднему меатотимпанальному углу. Инъекции выполняют непосредственно в гипертрофическую ткань путем погружения в нее всего среза иглы. Введение раствора в гипертрофическую ткань осуществляют частями - инъекциями, выполняемыми на расстоянии не ближе 3 мм от мест каждого вкола, создавая депо препарата непосредственно в гипертрофической ткани. Способ обеспечивает повышение эффективности лечения при снижении дозы вводимого препарата, увеличении времени его рассасывания из созданного ...

Hypodermic needle destruction

A device for destroying medical needles passes an electric current through the needle 2 to soften or melt it and then compresses the needle longitudinally to deform it into a lump. The device 110 has a housing (112, figure 4) with an aperture 114 into a chamber for receiving the needle; the chamber is heated to prevent the formation of condensates. Within the housing is: a first electrode 116 for clamping the needle at or near its hub; a second electrode 120 for contacting the needle at its sharp end and applying a compressive force; and a control system, operable to cause a current to flow in the needle between said first and second electrodes. Alternatively, the needle may be heated through electromagnetic induction. The chamber may be flushed by an inert gas. The compressive force may be provided by a spring, solenoid, motor or manually. Residual metal may be removed from the housing by an automated cleaning mechanism.

Griphub Tool

Needle sheath

Pharmaceutical device for the administration of substances to patients

Biological materials such as vaccines can be stabilised in certain glassy materials soluble in water. It has been proposed to form these glassy materials as a powder suspended in a non-aqueous liquid for injection into a patient. This method is complicated by the need to find suitable compatible liquids and to stop the glassy particles from congregating in liquid. These problems have been obviated by supporting the glassy material on a porous membrane 5 remote from the eluant. When the biological material requires administration, the eluant can be passed across the membrane 5 dissolving the glass and causing the substance to be carried by the liquid into the patient.

The temperature activated material may be a bi-metal, bi-plastic or shape memory alloy. The device may include an indicator14showing the state of the temperature sensitive lock. The container may be a vial1or a syringe22.

Improvements in hypodermic needles and syringes to be used therewith

... 141,423. Everett, S. J. Jan. 13, 1919. Syringes.-The needle of a hypodermic syringe passes through an india-rubber packing adapted to be compressed so as to make a tight joint between the needle and the syringe. The needle is grcoved, corrugated, or screw-threaded at the part engaged by the packing. In the form shown in Fig. 3, the screw-threaded portion b of the needle a is received within a tubular or solid rubber packing g contained in a union e attached to the nipple c of the syringe. The packing is compressed by means of a nozzle i which is screwed on to the union e and forces inwardly a sleeve or gland h. The outer end of the gland h may be split to form jaws which are compressed round the needle by a tapered portion of the nozzle i. The inner end of the needle may be chamfered to engage a stop-pin l in the nipple c. In a modification, the nozzle i screws within the union c and presses directly against the washer g. In a further modification, Fig. 5, a wasber g<2> is compressed by ...

Single use safety syringe

A single use safety syringe ( 10 ) has a barrel ( 12 ) having a leading end ( 14 ) and a trailing end ( 16 ). A needle 18 is sealably, but removably, attached to an opening in the leading end. A plunger ( 20 ) is slidably received through an opening in the trailing end. Upon completion of an injection, the plunger ( 20 ) engages the needle ( 18 ) and the needle can then be manually re-tracted into the barrel ( 12 ). A locking tab assembly ( 42, 44, 50, 52 ) is securely connected to a main body of the barrel ( 12 ) and forms the opening in the trailing end ( 16 ). The locking tab assembly includes two locking fingers ( 78, 80 ). The plunger ( 20 ) has a locking plate ( 41 ) which includes two locking ports ( 86, 88 ). The locking fingers ( 78, 80 ) and locking ports ( 86, 88 ) form a needle locking assembly. The locking fingers ( 78, 80 ) are adapted to engage by a hooked fit the locking ports ( 86, 88 ) when the needle ( 18 ) is fully retracted after use to prevent any subsequent movement of the plunger ( 20 ) with the engaged needle towards the leading end. Upon such engagement, a holding plate ( 36 ) secured to the plunger ( 20 ) below the locking plate ( 41 ) butts up against the bottom of holding rings ( 82, 84 ) of the locking tab assembly to prevent any subsequent movement of the plunger with the engaged needle towards the trailing end.
