Description
Technical field
This utility model product belongs to medical instruments field, specially refers to a kind of band remaining needle burette type transfusion apparatus in patient's infusion medicinal liquid process.
Technical background
At present, burette type transfusion apparatus is applicable to infantile infusion and the accurate needs of infusion monitoring dosage, and burette can accept medicinal liquid from infusion vessel, can become fully after closing one independently, the reservoir of air inlet voluntarily carries out infusion.After medicinal liquid is totally lost, in burette, shutoff valve will seal infusion channel voluntarily, play the automatic liquid-stopping effect, prevent the adverse consequences of blood backflow or aeroembolism.But all need because syringe needle for transfusion device adopts stainless pin and each transfusion the vein blood vessel that punctures, cause the vein blood vessel mechanical injuries.Be to guarantee clinical transfusion safety, research and development are produced and can repeatedly be infused and do not need the product of repeated localised puncture blood vessel to become focus and the difficult point of present research.And venous detaining needle is widely used, and is the new high-tech product that can repeatedly infuse for avoiding the repeated localised puncture vein blood vessel in the world at present, is the renewal product of transfusion needle.The remaining needle sleeve pipe is soft, grows and do not have the risk of thorn perforating veins at the intravenous indwelling time.In day by day heavy nursery work, use venous detaining needle to can be medical personnel and reduce workload, improve working efficiency.
(patent No.: 200810016948.0) proposed the band retaining needle type infusion apparatus, this transfusion device can improve the transfusion needle application risk to Chinese patent, but lacks clinical specific aim, uses colony's target indefinite.
Summary of the invention
The technical problems to be solved in the utility model is: the technological deficiency that above-mentioned existing transfusion device uses lacks clinical specific aim, can not satisfy the use needs of special group.It is simple in structure that this utility model provides, and burette type transfusion apparatus and venous detaining needle reasonable combination have the band remaining needle burette type transfusion apparatus that burette and remaining needle use function.
This utility model is to adopt following technical proposals to realize: a kind of band remaining needle burette type transfusion apparatus.Comprise bottle plug puncture unit assembly, air filter, ON/OFF clip, burette assembly, dropper, long tube, liquid medicine filter, flow regulator, injection member, outer cone joint etc.Feature is: the burette upper end is connected with the lower end of bottle plug puncture unit assembly, forms feed pathway.The dropping funnel place is connected with injection seat by long tube in the burette lower end, and injection seat and outer cone joint connect together.Its outer cone joint lower end connection one venous detaining needle forms liquid outlet channel.
Venous detaining needle described in the utility model comprises remaining needle sheath, conduit, nook closing member, the pin wing, needle tubing, sealing member, pipe clamp, retaining needle flexible tube, catheter block, infusion connector, fungi-proofing block (perhaps calparine cap), links together by infusion connector and outer cone joint.
This utility model is compared with prior art: the adverse consequences that the draw point of can avoiding infusing uses does not have the risk of thorn perforating veins in infusion process.Particularly adopt this transfusion device for infantile infusion and the patient who needs accurate infusion monitoring dosage, have more safety, the reliability of transfusion.
This utility model is by burette type transfusion apparatus and venous detaining needle reasonable combination, and it is simple in structure, and manufacturing process is simple, and uses simply, has the dual use function of burette and remaining needle.
