Description
Technical Field
The invention relates to a medical apparatus, in particular to an infusion apparatus capable of automatically stopping intravenous drip input
Background
Intravenous drip infusion is a method of infusing a large amount of sterile liquid, electrolyte and medicine into the body from veins by utilizing the principles of atmospheric pressure and hydrostatic pressure. At present, the known transfusion device is composed of a hose, a drip cup, a needle base, a sealing cover, a flow regulator, a liquid medicine needle, a needle handle and a needle head protective cover. Under the action of atmospheric pressure, the liquid medicine in the infusion bottle flows into the drip cup from the infusion hose, and when the pressure of water columns in the hose and the drip cup is larger than the pressure of veins in a human body, the liquid in the infusion bottle flows into the veins from the hose. However, the traditional infusion apparatus is not perfect in drip cup design, and people need to adjust liquid medicine to flow in time to replace an infusion bottle or pull out a needle after the liquid medicine in the infusion apparatus is completely infused, otherwise, the problem of blood backflow can be caused because the pressure of blood vessels in the body is greater than the pressure of an empty bottle of the infusion apparatus.
Even if a patient is cared by a guardian during transfusion, the medical staff can be called in time to handle after the liquid medicine is input, so that the condition of blood return can be effectively prevented, but the guardian can be mentally tired due to long-time care, and the patient is also decocted for the guardian. Many patients even do not look after the guardian, and only can look at the infusion bottle at any time, otherwise, the patient is dangerous. Moreover, when the hands of the hospital are not enough, the medical staff can not look after the patient in time, and the ordinary infusion apparatus can not automatically stop the intravenous infusion, so that inconvenience is brought to the medical staff and the patient.
In order to overcome the defects in the technology, scientific research personnel have proposed various infusion apparatus technical schemes capable of automatically stopping liquid:
the drip cup is made into a funnel shape, and a funnel-shaped floating plug is arranged in the drip hopper; the drip cup is made into a funnel, and a hollow buoyancy ball is arranged in the funnel; the existing disposable infusion set is improved, but the obvious defects still exist, so the disposable infusion set cannot be accepted by the market in a large range, and the disposable infusion set is characterized in that:
although the existing sinking-floating device can effectively prevent air intake and blood return in the infusion tube, in order to enable the floating plug to be aligned with the infusion hole, the position of the floating plug needs to be completed by a person through an adjusting ball above the dropping funnel; or the effective device is deviated and inverted in the transportation and use processes, so that the positioning is not accurate enough, the blockage is not tight enough and the blockage cannot be effective; or the shape of the sealing device is changed due to the action of external force, so that the ideal effect cannot be achieved; or the original advanced function of the drip cup that the original elastic material of the drip cup can not be played is changed. This is more likely to be the case because of the more undesirable consequences that may arise when relying on this technique.
Therefore, it is a problem to be solved urgently to provide a more advanced infusion device which has a high safety factor, is easy to operate, is more accurate, and maintains the excellent functions of the original infusion device.
Disclosure of Invention
In order to overcome the defect that the conventional infusion apparatus cannot automatically stop infusion, the invention provides an infusion apparatus capable of automatically stopping intravenous infusion, which aims to solve the problem that blood returns when the infusion of the infusion apparatus is finished and the liquid medicine in the infusion apparatus is smaller than the pressure of a vein in a human body in the prior art.
The technical scheme adopted by the invention for solving the technical problems is as follows: the device comprises an upper hose provided with a liquid medicine needle, the other end of the upper hose is connected with a drip cup, a sterile buoyancy ball is arranged in the drip cup, a concave spherical surface is arranged at the bottom end of the drip cup, and a concave spherical surface-shaped protective shell is arranged outside the concave spherical surface to ensure the completeness of the concave spherical surface without deformation. The distance between the edge of the concave spherical surface and the inner wall of the bottom of the drip cup is less than the radius of the sphere, so that the beads can fall from any place of the drip cup into the concave spherical surface at the lower part of the drip cup when the liquid medicine is lower than a certain amount. The surface of the buoyancy bead is a frosted surface, and the surface and the lower concave frosted surface can be closely combined under the dual functions of the gravity of the bead body and the suction force of the residual liquid medicine in the hose, so that air and liquid medicine can be prevented from entering the lower infusion hose, and the liquid medicine in the lower hose can not flow into the veins of human bodies any more. The liquid medicine at the lower part can maintain a certain pressure so as to prevent the blood in the human body vein from flowing into the infusion pipeline through the needle head, the drip cup is connected with a lower hose, the lower hose is provided with a flow regulator, meanwhile, the lower hose is connected with a needle seat through the flow regulator, the needle seat is provided with an infusion needle catheter, the other end of the infusion needle catheter is provided with a needle handle, and the needle handle is connected with an infusion needle tube.
The invention has the beneficial effects that: on the basis of keeping numerous advantages of the existing transfusion device, the tight combination of the buoyancy bead and the non-deformable concave spherical contact surface at the lower end of the drip cup realizes the automatic liquid stopping function, solves the problems that the liquid medicine cannot be replaced in time during medical transfusion and the liquid medicine cannot be stopped to be continuously input into the human body under the unsafe condition, prevents serious consequences caused by the liquid medicine, and has simple structure.
