The working principle is as follows: when sucking liquid, the trigger of the injection booster is in the state of not being pulled, i.e. reset, and the injection button is in the state of not being pressed. One end of the infusion tube is sleeved on a conical tube of the injection tube of the suction and injection dual-purpose injection booster, and the other end of the infusion tube is inserted into a bottle filled with liquid. An operator simultaneously presses liquid suction buttons positioned on the outer sides of a gun shell I and a gun shell II of the gun body by using two fingers, after the spring II is compressed, a liquid suction push rod pushes driving pins positioned at opposite angles of a trigger extending out of a longer water caltrop, namely in 2U-shaped side surface circular holes of a U-shaped groove, to simultaneously slide inwards from two sides, and then the spring III is compressed by a pressure head; when the distance between the large-diameter joint surfaces and the small-diameter joint surfaces of the 2 pressure heads at the two ends of the spring III is smaller than or equal to the distance between the inner surfaces of the two side surfaces of the U-shaped groove of the locking plate, the locking plate swings around a pin shaft IV hinged in a circular hole in the middle of the bracket towards the center direction of the pressure head, and the circular arc surfaces of the 2 semi-circular grooves below the rear part of the locking plate can be loosened when being attached to the small-section outer cylindrical surface of the pressure head. At this time, due to the limitation of the locking plate, the compressed spring iii cannot extend, and the driving pins on the two sides cannot be pushed outwards by the pressure head. Therefore, the inner ends of the 2 driving pins are respectively hinged with one end of the 2 connecting rods I, and the outer ends of the 2 driving pins are completely separated from the chain sheets. Meanwhile, the imbibing button is reset under the action of the spring II.
An operator holds a pistol handle by hands, a trigger is pulled by fingers, after a spring is compressed by the trigger, a connecting rod I is driven through a driving pin, one end of a rocker arm close to an auxiliary push rod swings towards the direction close to a barrel, the other end of the rocker arm swings towards the direction far away from the barrel through the middle of a connecting rod II, and the farthest end of the rocker arm far away from the rocker shaft drives a boosting sleeve sleeved on the excircle of a clamping sleeve close to the barrel through a connecting rod III and slides towards the direction far away from the barrel. Because the one end that the barrel was kept away from to the centre gripping cover is equipped with outer circular cone pipe section, and the cylinder pipeline section of centre gripping cover is kept away from to the main aspects of outer circular cone pipe section, and the centre gripping cover has a plurality of grooves along the circumferencial direction of centre gripping cover evenly to be cut, and the centre gripping cover has elasticity. When the boosting sleeve slides from the cylindrical section of the clamping sleeve to the outer conical section, the inner diameter of the boosting sleeve is smaller than the diameter of the large end of the outer conical pipe section of the clamping sleeve, so that the clamping sleeve is gradually clamped on the boosting rod by the boosting sleeve through the outer conical pipe section of the clamping sleeve, and the boosting rod is driven and the plunger rod and the plunger are driven to move towards the direction far away from the closed end of the injection tube through the transmission plate. Negative pressure is formed due to the gradual increase of the volume of an inner cavity formed by the plunger, the inner diameter of the injection tube and the closed end of the injection tube, so that the liquid in the bottle is sucked into the injection tube.
After the liquid is sucked for one time, the trigger is released, the trigger is reset under the action of the spring I, and the boosting sleeve is driven to slide towards the direction close to the gun barrel according to the transmission route opposite to the transmission route. The outer conical pipe section at one end of the clamping sleeve and the elastic action ensure that the boosting sleeve loosens the clamping sleeve clamped on the boosting rod, so that the boosting sleeve cannot stir the clamping sleeve to slide at the beginning of the reset of the trigger, and the boosting rod stays at the original position without moving; only when the boosting sleeve contacts the outer circular convex shoulder of the clamping sleeve, the clamping sleeve is driven to slide by the convex shoulder. However, since the clamping sleeve does not clamp the push-aid rod, the plunger and the like will still stay in place, and the liquid pressure in the syringe will also remain unchanged. When the trigger is fully reset, the trigger is pulled again to repeat the above action, i.e., a portion of the liquid is again drawn into the syringe. The liquid in the bottle can be continuously sucked into the injection tube by repeatedly pulling the trigger. The two sides of the outer cylindrical surface of the injection tube are provided with scale marks, so that the quantity of the sucked liquid can be accurately controlled, when the quantity of the liquid in the injection tube reaches the requirement, the trigger is stopped to be pulled, and then the infusion tube sleeved on the conical tube of the injection tube is pulled off.
When in injection, the trigger is in an unbuckled state, namely a reset state, the imbibition button is in an unbuckled state, and the infusion tube which is arranged in the parturient and is extended outwards from the disposable cervical dilatation balloon is sleeved on the conical tube of the injection tube. An operator presses an injection button located on the outer side of a gun shell I of a gun body, after a spring is compressed II, a hemispherical head of an injection push rod pushes a short rocker arm II to swing towards the direction away from the gun shell I and the end part of the short rocker arm II is far away from a short rocker arm shaft, and the short rocker arm I is driven to swing towards the direction close to a gun barrel through the short rocker arm shaft, so that a locking plate is pulled around a pin shaft IV through a pull rod, and 2 semicircular grooves below the rear portion of the locking plate swing towards the direction away from a pressure head. Once the locking tab is clear of the restraint of the ram and spring iii, spring iii will suddenly expand and push the drive pin outward by the ram. At this time, the inner ends of the 2 driving pins are completely separated from the connecting rod I, and the outer ends of the 2 driving pins are respectively hinged with one end of the 2 chain pieces. Simultaneously, the fingers are released, and the injection button is reset under the action of the spring II.
An operator holds the gun handle of the gun body by hand, pulls the trigger to compress the spring I, and pulls the shifting fork to swing around the shifting fork shaft and towards the direction close to the gun barrel through the chain sheet; meanwhile, the shifting fork shifts the boosting sleeve sleeved on the excircle of the clamping sleeve far away from the gun barrel to slide towards the direction close to the gun barrel through the U-shaped groove arranged at one end of the shifting fork. Similarly, the driving plate drives the plunger rod and the plunger to move towards the closed end of the injection tube, so that a part of liquid in the injection tube is injected into the disposable cervix dilatation balloon in the lying-in woman due to the pressure increase in the injection tube.
After the liquid injection is finished, the trigger is released, the trigger is reset under the action of the spring I, and the boosting sleeve is driven to slide towards the direction far away from the gun barrel according to the transmission route opposite to the transmission route. For the same reasons as described above, the clamping sleeve does not grip the push-aid rod, and therefore the push-aid rod, as well as the plunger rod, plunger etc. will remain in place, and the liquid pressure in the syringe will remain unchanged. When the trigger is completely reset, the trigger can be pulled again to repeat the actions, namely, a part of liquid is injected into the disposable cervical dilatation balloon in the parturient body again. The trigger is repeatedly pulled for a plurality of times, and then the liquid can be continuously injected into the disposable cervical dilatation saccule. The scale lines arranged on the two sides of the outer cylindrical surface of the injection tube can accurately control the amount of the injected liquid, and the injection is stopped when the cervix and the vagina of the parturient reach the expected expansion degree.
Compared with the prior art, the utility model is provided with the conversion device, and the boosting mechanism in the gun body is provided with 2 transmission lines which can be freely converted, and the directions of 2 clamping sleeves sleeved in 2 lines on the same 1 boosting rod are opposite; the large end of the outer conical pipe section with one end of the elastic clamping sleeve is far away from the cylindrical pipe section of the clamping sleeve, and a plurality of grooves are uniformly cut along the circumferential direction of the clamping sleeve, so that when the boosting sleeve slides to the outer conical section from the cylindrical section of the clamping sleeve, the clamping sleeve can be gradually clamped on the boosting rod, the boosting rod is driven, and the plunger is driven to move through the transmission plate. When the imbibing button is pressed down and the route II is selected, the liquid in the bottle can be imbibed into the injection tube by pulling the trigger; when the injection button is pressed down and the route I is selected, the trigger is pulled to inject the liquid in the injection tube into the disposable cervical dilatation balloon in the parturient. Therefore, the time and the labor are saved, and the labor intensity of operators is greatly reduced. Because the scale marks are arranged on the two sides of the outer circle of the injection tube, the quantity of liquid sucked into the injection tube or injected into the body of a lying-in woman can be accurately controlled, the pain of the lying-in woman caused by the overlarge quantity of the input liquid can be avoided, and the effect of dilating the cervical orifice and the vagina cannot be achieved due to the insufficient quantity of the input liquid.
