Definitions
- the invention belongs to medical engineering, in particular to injection syringes of single - use having means of protection from re-use of a syringe and traumatizing by a 5 needle after injection.
- the known devices provide guaranteed single use but do not prevent from 15 traumatizing by a needle after injection, and consequently do not defend from possible transfer/dissemination of infectious disease at use of a syringe.
- the drawback of the known device adopted as prototype is a number of composite manipulations after extraction of a needle from a body of the patient, stipulated by the necessity of moving a rod forward to lock the connecting plates of the
- the injection syringe having with the stated design solution common essential signs: a cylindrical barrel open from two sides, in one of which is the syringe needle with an axial channel, located inside the barrel piston with a rod and clamp on its end, and also means of protection from reuse of the syringe and prevention from traumatizing by the distal end of a needle after injection. Its peculiarity is that this syringe additionally contains a partition/seal, actuator and diaphragm located above the piston.
- the injection needle is hardly mounted on the partition that has diametrically arranged windows, and the bottom part of the injection needle is installed under partition and passes/runs through the diaphragm for connection of the axial channel with the chamber of the barrel, and device protecting from re-use of a syringe and traumatizing by a needle is manufactured as thin-walled sheath, that is installed without clearance on a syringe needle and fixed on actuator located in the barrel above the partition with the ability of lengthwise travel and having an axial channel for pass of the injection needle and diametrically arranged legs for pass through windows of the partition, the legs of the actuator are supplied with wedge - shaped supports with installed above and below pivotal/bearing/supporting sites for locking actuator on the partition at open and closed positions of distal end of the syringe needle.
- the indicated essential signs are indispensable and sufficient for implementation of the invention and achievement of technical result.
- the invention is also peculiar by the fact that the diaphragm is executed in the form of a bushing located below funnel of domed surface passing into an axial channel, at the end of which is thin-walled partition punched at syringe assembly by the rear point of the syringe needle for connection of its channel with the barrel chamber and at the top has stepped in cross-section cylindrical cavity, thus the piston from above is supplied with the cone for going into the funnel at transfer of the actuator with the protective sheath by the diaphragm along a syringe needle and blocking/covering its distal end.
- legs of the actuator from an exterior side have downwards-directional V-shaped lugs/cams, the form of which corresponds to the form of the stepped cavity of the top of the diaphragm.
- the invention is peculiar by the partition which is supplied with located below fitting pipe/nipple, co-axial to the barrel, for fixation of the rear end of the injection needle, and the axial channel of the diaphragm is executed by a sheer /through pass into it of this nipple and connection of the channel of the injection needle with the barrel chamber.
- V - shaped supports at the ends of actuator's legs the form of which corresponds to the form of a stepped cavity of the top part of the diaphragm, allows to prevent disconnection of the diaphragm and actuator at rarefaction in the chamber arising at fast intake of liquid by the syringe.
- Fulfillment of the diaphragm is executed in the form of a bushing located below funnel of domed surface passing into an axial channel, at the end of which is thin-walled partition punched at syringe assembly by the rear point of the syringe needle, and piston with the cone in the front part that allows to compact the needle in the diaphragm and increase the volume of injected liquid.
- Injection syringe (fig. 1, 2 and 4) consists of a barrel 1 and located in it with the possibility of lengthwise travel rod 2 with the cylinder piston 3, actuator 4 and diaphragm 5, located between the actuator and cylinder piston.
- the barrel 1, made from the polymer material, is opened from two sides and in the middle from the front side has a partition 6 in the form of the rod, in which the syringe needle 7 is firmly fixed with an axial channel 8 and rear end, outstanding under the rod, 9.
- windows 10 (fig. 4). Outside and at the rear end barrel 1 has a stop plate 11, and in its butt end - cylindrical turnery 12 and located behind it cylindrical V-shaped in cross-section ledge 13 (fig.
- Rod 2 made from polymer in the form of a rod with fins of rigidity/hardness 14 and has in front stepped tip 15 for installation of the cylinder piston 3, and behind - clamp 16, proportional cylindrical turnery 12 and V-shaped detents 17 (fig. 5 and 8), directed to the opposite side from ledge 13 of barrel 1 for fixation of rod 2 in the front extreme position, when its clamp 16 will enter flush cylindrical turnery 12 of barrel 1.
- the cylinder piston 3 is made from bergaflex (modified rubber) in the form of a cap with compressive cylindrical ledges 18 (fig. 6 and 7) on its outside surface, diameter of which exceeds internal diameter of chamber 19 of barrel 1 and created in front cone 20.
- Actuator 4 is made from polymer material is a barrel, proportional to the internal diameter of the front end of a barrel 1 with legs 22, through axial channel 23 for pass of the injection needle 7 and concentric to it cylindrical jack/socket 24 (fig. 8) for the installation of a thin protective sheath 25 of injection needle 7.
- Outside at the end of legs 22 are created directed back V-shaped ledges 26, and in the middle - oppositely arranged forward directional V-shaped supports 27 with upper 28 and lower bearing sites 29 for interaction with partition 6 in the front and back positions of protective sheath 25 of injection needle 7.
- Diaphragm 5 is made from bergaflex in the form of a bushing with cylindrical compressor ledges 30 at the outside surface, the size of which exceeds the diameter of chamber 19, and inside it there is stepped cavity 31, conforming to the form/shape and sizes of leg ends 22 for reliable fixation of the diaphragm on the actuator and avoidance of their disconnection at intake of liquid by the syringe.
- Behind diaphragm 5 is conical funnel 32 domed surface with central cylindrical channel 33, at the end of which is a thin-walled partition 34, punched at assembly of the syringe by a rear end 9 of injection needle 7 for connection of its channel 8 with chamber 19 of barrel 1 and seal it with the diaphragm.
- the syringe prepared for intake of liquid, injection needle 7 is closed by cap 35, and the syringe is packaged into a protective case (not shown).
- the distal end of injection needle 36 protrudes from protective sheath 25, and rod 2 is protruded from barrel 1 to 5 mm.
- fitting pipe/nipple 38 is created below partition co-axial to barrel 1, in which the rear end 9 of injection needles 7 is hard- mounted, and axial channel 33 of diaphragm 5 made through and the said fitting pipe 38 enters it for connection of the injection needle with chamber 19 of the barrel.
- the application of the said medical syringe allows eliminating its reuse, guaranteeing prevention from traumatizing by the distal end of the needle after injection and excluding the possibility of carry incurable or difficult to cure infection diseases.
