Abstract
The utility model relates to a medical intravenous drip injector, which solves the problem that when intravenous drip injection finishes, outside air can be prevented to enter the bodies of patients through an intravenous drip bottle and a thin pipe, and comprises a cylinder-shaped pipe body, a baffle plate and a sphere. An outlet for medical liquid is arranged on the pipe body. The baffle plate is arranged in the tube. The center of the baffle plate is arranged in the tube and the center of the baffle plate is provided with a circular slot hole. The sphere is arranged on the baffle plate in the tube body. The diameter of the sphere is greater than the circular slot hole. After the sphere fall on the circular slot hole the baffle plate can be completely sealed. The utility model can prevent air to enter, and can be widely used for medical service.
Description
This utility model relates to medical dropping syringe, refers to a kind of drop auto-stopper especially.
Existing dropping syringe only possesses one by flow controller that skewed slot and roller constituted, the injection volume and the time of this controller may command drop, and can't be after fluid infusion finishes, prevent that outside air from entering in patient's body, need visual by human eye, when drip off finish after, other changes one bottle of agent liquid, or stops fluid infusion and dial and remove syringe needle.The visual control mode of this human eye, if carelessness is arranged slightly, when dripping off, air is just taken advantage of a weak point, need and medical personnel to inject liquid with the air eliminating that enters in the tubule with another syringe, to recover the bottle effect of holding of drop, so just cause the waste of consumption, time and work, and make troubles and tired brain.
The purpose of this utility model is exactly to have the problems referred to above and provide a kind of and can prevent in the air admission patient body in view of existing fluid infusion, and can control the drop auto-stopper of fluid infusion process automatically.
The purpose of this utility model is achieved in that the drop auto-stopper, system is located on the body of junction point drop bottle and syringe needle, comprising a cylindric body, a dividing plate and a spheroid, there is potion liquid inlet the upper end that it is characterized in that this cylindric body, and then there is the outlet of potion liquid the lower end of body; Dividing plate system is located at cylindric body inside, and dividing plate central authorities also are provided with a circular slotted eye; Spheroid system is located at cylindric body inside, dividing plate top, but in enclosed baffle after on the circular slotted eye and its diameter circular slotted eye greater than dividing plate central authorities that drops.
Such scheme can be by the action of gravity of an internal partition and a spheroid, closed tube automatically so that liquid uses up in a drop bottle, and stoping outside air through a drop bottle, tubule and entering in patient's body.
The utility model is described in further detail below by drawings and Examples:
Fig. 1 is this utility model embodiment and outside drawing after external device (ED) is connected;
Fig. 2 is the overall appearance sketch map of this utility model embodiment.
Among the figure: 1 drop bottle, 2 volume control devices, 3 drop auto-stoppers, 4 syringe needles, 5 doses of liquid, 6 bodys, 31 cylindric bodys, 31a agent liquid inlet, the outlet of 31b agent liquid, 32 dividing plates, the circular slotted eye of 32a, 33 spheroids.
As shown in the figure: wherein spheroid proportion less than agent liquid greater than air.Its median septum and circular slotted eye for the benefit of spheroid enter the tram and are fixed and be designed to be funnel-form.Near its median septum plate face circular slotted eye is thinner, and tiltedly stretches and be to be shaped with the tool elastomeric material to central authorities.Why select tool elasticity, be so that spheroid can be closely connected with circular slotted eye fully, but make in the dividing plate complete closed air admission patient body, simple and reliable practical and convenient.
