Abstract
The utility model discloses a disposable venous indwelling needle which comprises a puncturing indwelling unit, an outer liquid infusion unit and a connecting pipe connecting the puncturing indwelling unit and the outer liquid infusion unit. The puncturing indwelling unit comprises a puncturing component for punching the body surface of a patient and an indwelling component indwelled inside the patient body. The puncturing component is inserted into the indwelling component in a sealed mode and capable of being removed from the indwelling component. After the puncturing component is removed from the indwelling component, an infusion channel for circulation of outer liquid is formed in the indwelling component. The connecting pipe is connected on the indwelling component and communicated with the infusion channel. The disposable venous indwelling needle is reasonable in structure, strong in practicability, and capable of effectively solving the problems that a infusion connector is likely to prick or puncture medical staff by a needle, bring in sealed material particles on a heparin cap and cause serious or potential hematogenous pathogen infection.

Summary of the invention
Problem to be solved in the utility model just provides a kind of disposable use venous detaining needle, rational in infrastructure, practical, can effectively solve the sealing substance granule of bringing into when existing infusion connector may cause medical personnel by pricking wound and needle point puncture on the calparine cap, the problem that causes serious or potential blood-borne pathogens to infect.
In order to achieve the above object, this utility model adopts following technical scheme: disposable use venous detaining needle, comprise puncture indwelling assembly and outside liquid input module, and the connection tube that connects puncture indwelling assembly and outside liquid input module, described puncture is kept somewhere assembly and is comprised of the lancet and means of puncture sufferer body surface and the indwelling parts of keeping somewhere in the patient, described lancet and means sealing is inserted into to keep somewhere in the parts and also can removes from keep somewhere parts, after described lancet and means removes from keep somewhere parts, form the infusion channel for the outside liquid circulation in the described indwelling parts, described connection tube is connected to keep somewhere on the parts and is communicated with described infusion channel.
Further, described lancet and means comprises needle tubing and needle stand, the front end puncture sufferer body surface of described needle tubing, described needle stand is located at the rear end of needle tubing, described indwelling parts comprise conduit and catheter block, the front end of described conduit is retained in the patient, described catheter block is located at the rear end of conduit and is communicated with conduit, described needle tubing cooperates with conduit and is installed in the conduit and the front end of needle tubing stretches out conduit, described needle stand is positioned at the rear end of catheter block, described catheter block is provided with the catheter adapter that is communicated with connection tube, between catheter adapter and catheter block rear end, be provided with the sealing-plug of automatic airtight after needle tubing removes in the described catheter block, described catheter adapter, the front end of catheter block and conduit form infusion channel.
Further, the front end face of described conduit overlaps and is connected to a face with the mouth of pipe inclined-plane of needle tubing.When needle tubing and conduit thrust the sufferer body surface together, allow sufferer feel once to puncture, rather than needle tubing and conduit puncture for twice.
Further, the front end of described catheter block is provided with the tapering face, and the diameter of the front end of described tapering face is less than the diameter of the rear end of tapering face, and the front end of described tapering face is provided with the conduit chock and is connected with the rear end of conduit.The seamlessly transitting of tapering face can be avoided keeping somewhere parts the sufferer body surface is caused local compression.
Further, described needle stand is provided with the needle stand fin, and described catheter block is provided with the catheter block fin.Be convenient to hold the pin operation.
Further, described conduit is provided with the sheath that entangles conduit and needle tubing.Health is installed.
Further, described outside liquid input module comprises the plinth that is communicated with connection tube, and described plinth is provided with infusion connector.
Further, described infusion connector is needleless joint.Safety and sanitation.
Further, described plinth is provided with sub-joint, and described sub-joint is provided with block.Be convenient to dosing, block can be tightened on the sub-joint, also can be fixed by the tapering anchor ring.
Further, described connection tube is provided with the switch folder.Prevent when finishing transfusion decompression in the connection tube.
After adopting technique scheme, the utlity model has following advantage: 1, finish to infuse when carrying out washing pipe, need not to use syringe needle, avoid medical personnel to be caused autoinfection by pricking wound; 2, the sealing-plug of automatic airtight, the incidence rate of minimizing Catheter-related bacteremia; 3, without latex and DEHP, can be widely used in neonate, child, adult; 4, needleless joint produced malleation automatically after syringe was thrown off, and to keep the unobstructed of infusion channel, it is dangerous to reduce plugging; 5, level and smooth joint top, easily sterilization; 6, indwelling time reaches 72 hours and safe and reliable; 7, needle stand structure adopts single-blade ansa formula, is convenient to medical personnel and holds the pin operation.
