Abstract
The utility model discloses a prevent back blood transfusion system, including transfer line, bottle stopper puncture device, the piece that admits air, dropping funnel, flow regulator, filter, junction block, vein pjncture needle, the filter cup joints the protective sheath with the outside of junction block, is equipped with the suspension awl in the dropping funnel, when having the infusion in the dropping funnel, the suspension awl floats in the infusion. The utility model discloses in the use, can prevent effectively that filter and junction block from droing because of the tractive, the suspension awl floats in the dropping funnel when the infusion, can be close in the infusion preventing that blood phenomenon, safe and reliable from appearing back in the syringe needle when accomplishing.
Description
Technical field
This utility model relates to a kind of transfusion device of field of medical article technology, particularly relates to one and prevents blood-returning transfusion system.
Background technology
The transfusion device of medically a large amount of use at present, its structure is similar, arranges discerptible filter and junction block in one end of the close venipuncture needle of tube for transfusion, and junction block connects venipuncture needle, conveniently use when needs intravenous injection other medicines, avoid the misery that patient's repeated puncture is injected.But when actual clinical transfusion uses, still there is potential safety hazard, involve when causing coming off if this filter and junction block are subject to external force, very easily cause the junction of filter and junction block to pollute, consequence is serious; The time of transfusion is longer, when people does not know when transfusion completes, is easy to cause patient needle head part to occur blood back phenomenon, causes pain to patient, more especially have the patient of dizzy mass formed by blood stasis shape to cause a lot of trouble.
Summary of the invention
The purpose of this utility model is to provide one and prevents blood-returning transfusion system, can prevent syringe needle blood back at the end of transfusion soon.
For achieving the above object, the technical solution adopted in the utility model is:
One prevents blood-returning transfusion system, comprises tube for transfusion, bottle plug puncture unit, air intake, dropping funnel, flow regulator, filter, junction block, venipuncture needle, it is characterized in that: the outside of filter and junction block is socketed protective sleeve, is provided with the cone that suspends in dropping funnel; When there being transfusion in dropping funnel, suspension cone swims in transfusion.
Prevent blood-returning transfusion system according to described, it is characterized in that: the described lower end suspending cone is provided with conehead, and the diameter of conehead is less than the internal diameter of tube for transfusion, and conehead can be inserted in tube for transfusion.
Prevent blood-returning transfusion system according to described, it is characterized in that: in described suspension cone, be provided with hollow lattice.
The utility model has the advantages of and be: this utility model in use, can effectively prevent filter and junction block from coming off because of tractive, the cone that suspends floats on dropping funnel when infusing, and can prevent syringe needle from occurring blood back phenomenon when infusing close completing, safe and reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of boring that suspends in Fig. 1.
In accompanying drawing: 1, tube for transfusion; 2, bottle plug puncture unit; 3, air intake; 4, dropping funnel; 5, flow regulator; 6, filter; 7, junction block; 8, venipuncture needle; 9, protective sleeve; 10, suspend cone; 11, hollow lattice; 12, conehead.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
This utility model as shown in the figures 1 and 2, one prevents blood-returning transfusion system, comprise tube for transfusion 1, bottle plug puncture unit 2, air intake 3, dropping funnel 4, flow regulator 5, filter 6, junction block 7, venipuncture needle 8, it is characterized in that: filter 6 is socketed protective sleeve 9 with the outside of junction block 7, is provided with suspension cone 10 in dropping funnel 4; When there being transfusion in dropping funnel 4, suspension cone 10 swims in transfusion.Prevent blood-returning transfusion system according to described, it is characterized in that: the lower end of described suspension cone 10 is provided with conehead 12, the diameter of conehead 12 is less than the internal diameter of tube for transfusion 1, and conehead 12 can be inserted in tube for transfusion 1.Prevent blood-returning transfusion system according to described, it is characterized in that: in described suspension cone 10, be provided with hollow lattice 11.
Concrete principle of the present utility model is as described below: during use, is inserted in transfusion bottle by bottle plug puncture unit 2, opens air intake 3, and now transfusion can enter in dropping funnel 4, and now suspension cone 10 is at the effect float downward of buoyancy, then closes air intake 3, infuses.At the end of transfusion is fast, suspension cone 10 can decline along with the decline of liquid in dropping funnel 4, until conehead 12 can be inserted in tube for transfusion 1, now suspension cone 10 can be blocked the liquid outlet of tube for transfusion 1, make the liquid in tube for transfusion 1 cannot continue to be left in body, blood in body also cannot reflux, thus realizes anti-return blood.Hollow lattice 11 effectively can increase the buoyancy of suspension cone 10; The thing that flow regulator 5 often uses for prior art, for the speed of regulating transfusion flow rate of liquid.
Embodiment recited above is only be described preferred implementation of the present utility model; not design of the present utility model and protection domain are limited; under the prerequisite not departing from this utility model design concept; the various modification that in this area, common engineers and technicians make the technical solution of the utility model and improvement, all should fall into protection domain of the present utility model.
