Abstract

The invention provides a safety transfusion device. The safety transfusion device comprises a puncture outfit, a drop funnel, a filter net and a bracket, an inner floating body, a flexible tube, a filter and a vein needle which are arranged in sequence and are relatively and fixedly connected, wherein a flow controller is arranged out of the flexible tube; the bucket-shaped filter net and the bracket fixedly connected on the flexible tube are arranged in the drop funnel; the floating body is arranged in the filter net and the bracket; the floating body can be designed in a plane shape, a conical shape, a spherical shape, a piston shape, an arched shape, and the like; when the liquid is approximately dripped off, the floating body blocks the upper end opening of the flexible tube by means of gravity, so that the aim of safety transfusion is realized and the economical and social benefits of the safety transfusion device are greatly increased.

Description

Safe transfusion system

Technical field

The present invention relates to be used in a kind of medicine and hygiene fields the infusion set used when clinical patients is carried out venous transfusion; Specifically; Relate to and a kind ofly when venous transfusion, can filter big molecule granule and closing pipe line automatically at transfusion end; Prevent the thromboembolism that causes in the entering bodies such as air, foreign body, thereby reach the safe infusion purpose.

Background technology

When at present the patient being carried out venous transfusion, a large amount of use disposable transfusion devices prevent that like this cross infection from having played good effect, but weak point is also obvious; In recent years because the extensive application of Chinese patent medicine injection; Drug reaction also more and more more to be seen, generally is all the reactive molecule group of Chinese patent medicine processing when mixing with filtering microgranule and with other medicinal liquids and gets into that institute causes in the body, much is to neglect because of nursing to cause in the gas entering body with ining addition; Potential safety hazard when these all are transfusion; Simultaneously also strengthened very big labor intensity to nursery work, the present invention can address the above problem, and has greatly improved working efficiency and safety guarantee.

Summary of the invention

The object of the invention provides a kind of safe transfusion system, can prevent that unusual microgranule from getting in the body, and when its transfusion finished, closing pipe line prevented that effectively gas from getting in the body automatically, thereby reaches the purpose of safe infusion.

To achieve these goals, the present invention proposes a kind of safe transfusion system, comprise that perforator, dropping funnel, filter screen and the support, interior buoyancy aid, flexible pipe, filter, the intravenous needle relative fixed that are provided with in regular turn are formed by connecting; The external flow controller of flexible pipe wherein; The barrel strainer and the support that are fixedly connected on the flexible pipe are arranged in described dropping funnel, buoyancy aid is arranged in it, buoyancy aid can be designed to plane, taper, ball-type, piston-type, arch etc.; Liquid is when dripping off; Buoyancy aid is relied on power shutoff flexible pipe port for support, thereby reaches the purpose of safe infusion, has improved the economic benefit and the social benefit of this product greatly.

Embodiment 1

As shown in Figure 1; The present invention proposes a kind of safe transfusion system; Comprise in regular turn the perforator 1, flexible pipe 2, dropping funnel 3, filter screen and the support that are provided be fixedly connected become that filter cylinder 4, interior buoyancy aid 5 can move up and down in the filter cylinder 4 that do not coexist with liquid level, flexible pipe 6 upwards the portion of dividing a word with a hyphen at the end of a line be fixedly connected after to be that the outside lower end with filter cylinder 4, upper end of flexible pipe 11, flexible pipe 11 is inboard melt by means of solvent phase; Interior buoyancy aid 5 moves downward and can form the piston type shutoff with the medial wall of flexible pipe 11 upper ends; Filter 9 borrows solvent phase to melt the lower end that the back is fixedly connected, intravenous needle 10 is movably connected on filter 9, flexible pipe 6 external flow controllers 8 wherein, and flow controller 8 has the roller 7 that can move up and down; The fixed or movable in regular turn connection of above structure and be combined into the present invention.Its characteristic is that the filter cylinder that is fixedly connected on the flexible pipe is arranged in the dropping funnel in the above the present invention; The buoyancy aid that moves up and down is arranged in the filter; Contact surface can be designed to plane, taper, ball-type, piston-type, arch face etc. under the buoyancy aid; Liquid is when dripping off, and buoyancy aid is relied on power shutoff flexible pipe port for support and reached the object of the invention.

Claims
