Description

The intravenous transfusion device of the anti-return blood of a kind of energy
Technical field
This utility model belongs to technical field of medical instruments, specifically, relates to the intravenous transfusion device of the anti-return blood of a kind of energy.
Background technology
Intravenous transfusion device, as a kind of medical treatment consumptive materials of setting up passage between vein and medicinal liquid, great majority are to be connected to form by intravenous needle, helmet, infusion tube, exhaust apparatus, flow regulator, a kettle, bottle plug puncture unit, air inlet pipe air filter.This intravenous transfusion device is simple in structure and convenient in use, but, it in use, nurse or family members must note observing transfusion situation constantly, in order to avoid transfusion bottle herb liquid is totally lost and do not realize, thus when changing bottle and pulling out pin to medical personnel, patient and family members with serving unnecessary trouble and anxiety.
For fear of above-mentioned trouble, Chinese patent (CN 200820218841) just provides a kind of pin transfusion device that automatically stops, comprise tube for transfusion, speed regulator, transfusion bottle and syringe needle, on tube for transfusion, process two and regulate capsule, described adjusting capsule is oval spherical structure, communicate with tube for transfusion, internal diameter is greater than tube for transfusion diameter; Upper strata regulates capsule surface to connect exhaustor, and inside deposits stopper and ball float in, and bracing wire is connected stopper with ball float; During injection, regulate the air in capsule to extrude on upper strata, medicinal liquid flows to and regulates capsule along tube for transfusion, and now stopper is blocked tube for transfusion, and along with liquid level raises, ball float rises and drives stopper to depart from the tube for transfusion mouth of pipe, and transfusion device starts normal infusion; After medicinal liquid is totally lost, upper strata regulates the medicinal liquid of capsule first to decline, and ball float declines with liquid level, and when liquid level is less than bracing wire length, tube for transfusion is blocked in stopper tenesmus, and now transfusion stops.This invention has realized the self-closed of transfusion device to a certain extent, is difficult for coordinating with the mouth of pipe deficiencies such as the easy entanglement of bracing wire but still have stopper.
Summary of the invention
In order to solve the problems of the technologies described above, this utility model provides a kind of intravenous transfusion device of the anti-return blood of energy of simple in structure, easy to operate, good sealing effect.
The intravenous transfusion device of the anti-return blood of energy described in the utility model, described intravenous transfusion device is connected to form by sheath 1, perforator 2, conduit 3, Y-type three way type 4, a kettle 5, flexible ball float 6, Magnet 7, iron clamp 8, flow regulator 9, exhaust apparatus 10, venoclysis needle 11 and air-filtering membrane 12; Described kettle 6 upper ends are provided with air-filtering membrane 12, have the flexible ball float 6 of built-in Magnet 7 in kettle; Described iron clamp 8 is arranged on the conduit that drips kettle 6 lower ends.
The intravenous transfusion device of the anti-return blood of energy described in the utility model, described Y-type three way type 4 is connected by screw thread is detachable with a kettle 5.
The intravenous transfusion device of the anti-return blood of energy described in the utility model, described flexible ball float 6 is made for PVC material, and its diameter is less than the diameter of air-filtering membrane 12, is greater than the diameter of conduit 4.
The intravenous transfusion device of the anti-return blood of energy described in the utility model, described Magnet 7 is a hollow iron ball or the tiny iron ore of some grains.
The intravenous transfusion device of the anti-return blood of energy described in the utility model, outer being located on the conduit that drips kettle 6 lower ends of described iron clamp 8, and can move up and down.
The operation principle of intravenous transfusion device described in the utility model: while filling a certain amount of medicinal liquid in dripping kettle, flexible ball float buoyancy is greater than gravity, it drips kettle lower end channel opener in floating state, and medicinal liquid can be toward dirty; When dripping a kettle herb liquid, be less than when a certain amount of, flexible ball float buoyancy is less than gravity, and its whereabouts is also stopped up and dripped a kettle lower end passage, and medicinal liquid stops toward dirty.
Compared with prior art, the intravenous transfusion device of the anti-return blood of energy described in the utility model arranges movably iron clamp at the conduit that drips kettle lower end, relies on captivation, can change flexible ball float stressed size downwards; Flexible ball float is arranged to flexibility, deformation can occur when stressed, better with a kettle lower end passage fitted seal; It has advantages of simple in structure, easy to operate, good sealing effect.
Accompanying drawing explanation
Fig. 1 intravenous transfusion device structural representation, 1-sheath, 2-perforator, 3-conduit, 4-Y-type three way type, 5-drip kettle, the flexible ball float of 6-, 7-Magnet, 8-iron clamp, 9-flow regulator, 10-exhaust apparatus, 11-venoclysis needle, 12-air-filtering membrane.
The specific embodiment
Below in conjunction with specific embodiment, intravenous transfusion device described in the utility model is described further, but protection domain of the present utility model is not limited to this.
embodiment 1
An intravenous transfusion device for the anti-return blood of energy, described intravenous transfusion device is connected to form by sheath 1, perforator 2, conduit 3, Y-type three way type 4, a kettle 5, flexible ball float 6, Magnet 7, iron clamp 8, flow regulator 9, exhaust apparatus 10, venoclysis needle 11 and air-filtering membrane 12; Described kettle 6 upper ends are provided with air-filtering membrane 12, have the flexible ball float 6 of built-in Magnet 7 in kettle; Described iron clamp 8 is arranged on the conduit that drips kettle 6 lower ends; Described Y-type three way type 4 is connected by screw thread is detachable with a kettle 5; Described flexible ball float 6 is made for PVC material, and its diameter is less than the diameter of air-filtering membrane 12, is greater than the diameter of conduit 4; Described Magnet 7 is a hollow iron ball or the tiny iron ore of some grains; Outer being located on the conduit that drips kettle 6 lower ends of described iron clamp 8, and can move up and down.
