Definitions
- the device relates to medical equipment, namely to devices for intramuscular and subcutaneous injection.
- Automatic injector for standard medical syringes consisting of a body, springs, syringe holder, characterized in that the platoon plate interacts downward until the syringe lock locks into place under the influence of the physical force of the human hand, move downward until the lock locks into place, while the piston pusher made with the possibility of cocking, in accordance with the degree of filling of the syringe, rising to the height of the piston rod of the syringe, while the plunger of the piston is made with the possibility of cocking
- the gear rack and the piston pusher retainer fixes the piston pusher at different heights, while the syringe is inserted into the syringe holder, while the syringe holder is made possible to be released by the action of a person’s hand on the release button, while using the main spring interacting with the s
- the disadvantage is the rough operation of the device, the very fast introduction of the drug and the slow platoon of the device to its original operating state.
- JST patent ° 2571231.
- the invention relates to medical equipment, namely to automatic injectors for administering a dose of a liquid drug.
- the injector comprises: a tubular frame carrying a subassembly, overlapping an initiator cuff, an adjusting spring, four locking means.
- the bearing subassembly includes a tubular bearing element mounted with the possibility of sliding relative to the frame and partially located inside the frame, the bearing element comprising a syringe with a hollow injection needle, a drive spring and a piston in order to direct the load of the drive spring to the syringe stop, where the syringe fixed with a supporting element for joint axial movement.
- the overlapping cuff initiator is located on top of the distal end of the automatic injector and extends over at least almost the entire length of the automatic injector.
- An adjustment spring is located around the support element.
- the first locking means connects the proximal end of the control spring to either the carrier to advance it with the aim of introducing the needle, or to the frame for needle retraction, depending on the relative axial position of the supporting element and the initiator cuff.
- the second locking means allows the injection spring to be released when the carrier has almost reached the injection depth during insertion of the needle.
- the third locking means allows the frame to be connected to the supporting element for joint axial movement relative to the frame of the initiator cuff, while the third locking means allows the frame and the supporting element to be separated when the initiating cuff is moved in the proximal direction relative to the frame, thereby releasing the control spring for insertion needles.
- the fourth locking means allows the distal end of the control spring to be connected either to the supporting element for retracting the needle, or, otherwise, to the cuff initiator.
- the disadvantage is the great complexity of the design, and the difficulty in using.
- the technical result is to increase the efficiency of the device, reducing pain from the rapid introduction of drugs during injection.
- an automatic injector for medical syringes consisting of a body, a syringe holder, a piston pusher, a syringe elevator, a shutter button, a lifting spring, a needle input spring, an extrusion spring injection fluid, fuse and dynamic brake in the form of a damper mechanism.
- the main spring is made of two springs, namely, the needle input spring and the injection fluid extrusion spring provide a smoother, more stable operation of the device.
- a mechanical dynamic brake in the form of a damper mechanism ensures the slow introduction of the medicine from a standard disposable syringe and an easy quick cocking of the device into working condition.
- FIG. 1 shows a partial section through an “automatic injector for medical syringes”
- FIG. 2 shows an additional partial section
- FIG. 3 shows an additional partial section
- FIG. 4 shows an additional partial section
- the device is made and works as follows.
- the latch (17) is released from engagement with the housing (2).
- the input spring (8) moves: - the pusher (5), extrusion springs (11), the cartridge holder (4), the syringe holder cartridge (3) and the entire mechanical dynamic brake in the form of a damper mechanism (23).
- the movement takes place until the stop of the holder (4) in the lift (7).
- the syringe needle (1) is inserted to the required depth into the patient's body. After that, due to inhibition in the damper mechanism (23), the drug is injected at a slow speed due to the resistance of the damper lubricant (16) against the damper disk (13).
- the sample is made for sterilization from resistant to antiseptic solutions, as well as resistant to sterilization temperature in autoclaves, hygienically approved plastic material, metal parts - stainless steel.
