Manual injection booster

Abstract

The invention provides a manual injection booster. The manual injection booster is characterized in that a pin shaft I is respectively arranged on the inner surfaces of a gun shell I and a gun shell II; a supporting plate I, a supporting plate II, a sleeve pipe I and a sleeve pipe II are arranged in an inner cavity; an arc groove is arranged at the upper part of a gun body; a pin shaft II is respectively arranged at two sides of a trigger; two ends of a trigger shaft equipped with the trigger are supported on the gun shell I and the gun shell II; one ends of springs are hung on pin shafts I; the other ends of the springs are hung on pin shafts II; the extending end, penetrating through the supporting plate II and provided with a clamping sleeve and a boosting sleeve in a sleeving manner, of a boosting rod is inserted into the sleeve pipe I; two ends, fixedly equipped with shifting forks, of a shifting fork shaft are supported at the central parts of the gun shell I and the gun shell II; pin shafts III of the boosting sleeve are located in U-shaped grooves of the shifting forks; one ends of chain pieces are hinged with the central parts of the shifting forks; the other ends of the chain pieces are hinged with two ends of a chain pin; two ends of an injection tube are arranged in the arc groove located at the upper part of the gun body through hoops; one end, equipped with a plunger, of a plunger rod is inserted into the injection tube; and the other end of the plunger rod is connected with the end part of the boosting rod through a transmission plate. The manual injection booster provided by the invention is light and convenient to operate, and can easily and accurately control the injection liquid quantity.

Description

technical field [0001] The invention provides a manual injection booster, which belongs to the field of medical instruments and equipment, and is mainly used for boosting and pressurizing when injecting liquid into a patient, and can also be used for dispensing medicine before infusion. Background technique [0002] When the parturient gives birth, in order to shorten the labor process and reduce the pain of the parturient, the disposable cervical dilation balloon is generally placed in the uterus and vagina of the parturient, and then the liquid is slowly injected into the disposable cervical dilation balloon through the infusion tube to gradually expand it. , so as to play the role of dilating the cervix and vagina, so as to facilitate the smooth delivery of the fetus. [0003] At present, the commonly used injection booster devices are mostly plunger syringes, which need to be manually pushed by nurses to complete the injection input of liquid, which is labor-intensive, a...

AI Technical Summary

Problems solved by technology

[0003] At present, the commonly used injection booster devices are mostly plunger syringes, which need to be manually pushed by nurses to complete the injection of liquid, which is labor-intensive, and the amount of liquid injected is not easy to accurately control

When the amount of liquid injected is too large, it will bring more pain to the parturient, otherwise it will not achieve the effect of dilating the cervix and vagina
