The syringe is commonly used for medical care personnel to dispense medicine for transfusion, and the medicine dispensing for transfusion refers to that the syringe sucks liquid in the ampule bottle and then injects the liquid into a transfusion bottle. In the operation process, a palm is required to support the core rod, then the needle cylinder is clamped by fingers so as to enable the needle cylinder and the core rod to move relatively, liquid medicine in the ampule bottle is sucked into the needle cylinder, and then the liquid medicine in the needle cylinder is pushed into an infusion bottle to complete infusion dispensing.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an auxiliary device of syringe can replace the manual work to carry out the infusion and dispense.
In order to achieve the above object, the utility model provides a following technical scheme: an auxiliary device of an injector comprises a vertical support, wherein a mounting plate is arranged on the support, a driving mechanism and a fixing mechanism positioned below the driving mechanism are arranged on the mounting plate, the driving mechanism comprises an air cylinder and a piston rod driven by the air cylinder, and one side of the piston rod is connected with a clamping mechanism used for clamping a second connecting wing; the fixing mechanism comprises a sliding plate and a connecting plate fixed with the mounting plate, a first limiting spring is arranged between the connecting plate and the sliding plate, the sliding plate is vertically and slidably connected with the mounting plate, and one side of the connecting plate is abutted against one side of the sliding plate.
The utility model discloses a theory of operation: the scheme utilizes the structural characteristics of the injector, namely, a first connecting wing is fixed on a needle cylinder of the injector, a second connecting wing is fixed on a core rod, and the liquid absorption and the liquid discharge of the injector can be realized through the directions of the first connecting wing and the second connecting wing which are separated or opposite. The distance between the clamping mechanism and the connecting plate is adjusted, and the piston rod is driven to move upwards through the air cylinder, so that the distance is larger than the distance between the second connecting wing and the first connecting wing. The distance between the connecting plate and the sliding plate is adjusted, the sliding plate slides upwards at the moment, the distance between the sliding plate and the connecting plate is increased, the first limiting spring is stretched, the first connecting wing on the needle cylinder is placed between the connecting plate and the sliding plate, the sliding plate is released, the sliding plate moves towards the connecting plate, the first connecting wing is tightly pressed on the connecting plate, meanwhile, the piston rod is driven by the air cylinder to move, the piston rod drives the clamping mechanism to move, when the clamping mechanism moves right above the second connecting wing, the piston rod stops moving, the second connecting wing is clamped through the clamping mechanism, and therefore the injector is fixed.
Because the first connecting wing is fixed between the connecting plate and the sliding plate, the movement of the needle cylinder can be limited by the elasticity of the first limiting spring, the second connecting wing is clamped by the clamping mechanism, the piston rod moves upwards through the air cylinder, and the piston rod drives the core rod to move upwards, so that the core rod can move in the needle cylinder to realize liquid suction and liquid discharge. When the needle of the injector is inserted into the ampule bottle, the elastic force of the first limiting spring can prevent the sliding plate from moving and further prevent the needle cylinder from moving when liquid is absorbed, and when liquid is discharged, the connecting plate is fixed on the mounting plate and can limit the needle cylinder from moving through the first connecting wing.
The utility model has the advantages that: 1. the distance between the clamping mechanism and the connecting plate is adjusted through the air cylinder, when the second connecting wing on the core rod is clamped by the clamping mechanism, the first connecting wing can be tightly pressed on the connecting plate through the sliding plate, the injector is fixed, the clamping mechanism is driven to move through the air cylinder, the core rod is made to move, and liquid suction and liquid discharge can be achieved. 2. The distance between the sliding plate and the connecting plate is increased by sliding the sliding plate, so that the syringe is convenient to mount, one side of the connecting plate is abutted against one side of the sliding plate, and the first connecting wing is pressed on the connecting plate through the sliding plate. 3. Because the same syringe is adopted to operate when the same type of liquid medicine is prepared in a hospital generally, the scheme is that one syringe is arranged on the auxiliary device, so that the repeated preparation can be realized, and the manual liquid preparation is replaced.
The optimization of the basic technical scheme is as follows:
further, the sliding plate and the connecting plate are symmetrically arranged along the axis of the mounting plate. Through making connecting plate and sliding plate symmetry set up the both sides at the mounting panel, because first connection wing symmetry sets up the both sides at the cylinder, its aim at realizes fixing the first connection wing on the syringe through both sides, can make the core bar more steady at the removal in-process.
Further, the mounting plate is a telescopic plate. Because the syringe of different specification models, the section of thick bamboo footpath of cylinder differs, for the convenience is applicable to the syringe of more models, through establishing the mounting panel into the expansion plate, and its aim at makes the distance increase between the both sides connecting plate through the mounting panel is flexible to there is great space to put into the cylinder.
Furthermore, a linkage rod is connected between the sliding plates. The movement of the sliding plates at the two sides can be realized by pulling the linkage rod, so that the adjustment is convenient.
Furthermore, a second limiting spring is arranged between the connecting plates. When the mounting plate extends, the connecting plates on the two sides are driven to move, the second limiting spring is stretched, so that when the first connecting wings are clamped between the connecting plates and the sliding plates, the connecting plates and the sliding plates clamp the needle cylinder, and when the piston rod drives the core rod to move, the needle cylinder cannot swing left and right because the needle cylinder is clamped.
Further, clamping mechanism includes reciprocal lead screw and with reciprocal lead screw pole sliding connection's reciprocal piece, the one end and the piston rod fixed connection of reciprocal lead screw, one side of reciprocal piece is connected with the anchor clamps that are used for pressing from both sides tight second connection wing, the vertical sliding connection of reciprocal piece has the slide bar, the one end and the piston rod fixed connection of slide bar. The reciprocating block is driven to slide upwards by rotating the reciprocating screw rod, and when the clamp moves to the position above the second connecting wing, the clamp descends to clamp the second connecting wing by rotating the reciprocating screw rod due to the limitation of the sliding rod.
