Abstract
The invention relates to a fastener for a medical syringe needle, which comprises a needle, a needle tube, a push rod, a sleeve, a gland, a friction sleeve and a hollow jackscrew, wherein a central hole of the hollow jackscrew is more than an external circle of the needle and less than an outer diameter of a flange of the needle; the hollow jackscrew is sleeved on the needle and is in threaded connection with one end of the sleeve; the friction sleeve is sleeved in the other end of the sleeve; the other end of the sleeve is in threaded connection with one end of the gland through an external thread and is in threaded connection with the friction sleeve through an internal thread; and the friction sleeve is sleeved with the needle tube. The fastener for the medical syringe needle is exquisite and reasonable in design, convenient and reliable to use, and simple and easy to manufacture.
Description
Technical field
The present invention relates to the syringe in the medical apparatus and instruments, particularly relate to medication injections syringe needle fastener.
Background technology
The continuous lifting of Along with people's quality of life; The vigorous growth of shaping and beauty industry; Particularly some large-scale professional medical beauty treatment mechanisms have obtained the current vast fervent concern of asking beautiful person; Such as: new concept, new medical skill such as beauty+health, the beauty treatment of little shaping fashion and facial rejuvenation, ring fixed pattern liposuction suction art are arisen at the historic moment, and in many shaping and beauty projects, in treatments such as filling, fat transplantation, all need carry out high-pressure injection; This is because injection viscosity is higher, so injection thrust also needs corresponding increase.High-pressure injection adopts common medical syringe to be equipped with special-purpose propeller usually and accomplishes.Yet during self-locking frictional force between injection pressure is greater than syringe needle and needle tubing on the conical contact surface, the fault that syringe needle comes off takes place in regular meeting, influences normal running.
Summary of the invention
The technical problem that the present invention will solve is, provide a kind of can guarantee high-pressure injection the time syringe needle do not come off, and be the medication injections syringe needle fastener that common medical syringe is equipped with.
The technical scheme that adopts is:
Medication injections syringe needle fastener comprises syringe needle, needle tubing, push rod, sleeve, gland, friction sleeve, hollow jackscrew.Described hollow jackscrew is sleeved on the syringe needle, and hollow jackscrew is connected with the sleeve threaded one end, cover friction sleeve and be connected with the gland threaded one end with external screw thread in the sleeve other end.
Above-mentioned friction sleeve endoporus and needle tubing socket; The middle part of cylindrical is provided with undercut; Undercut one side is that fine thread is connected with internal thread of sleeve, and opposite side is and the close-fitting circular cone friction sleeve of gland endoporus that its circular cone friction sleeve increases elastic five equilibrium pintongs body for cutting apart to process.
Above-mentioned its centre bore of hollow jackscrew is set as greater than the syringe needle cylindrical again less than the syringe needle flange outside diameter.
The above-mentioned sleeve and the outer round surface of gland are configured to knurled surface.
Above-mentioned hollow jackscrew is six square toes jackscrews.
Deft design of the present invention is reasonable, and is easy to use and reliable, makes simple.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is A-A cutaway view of Fig. 1.
The specific embodiment
Medication injections syringe needle fastener comprises syringe needle 1, needle tubing 2, push rod 3, sleeve 6, gland 9, friction sleeve 7, hollow jackscrew 4.Described hollow jackscrew 4 is six square toes jackscrews, and hollow jackscrew 4 its centre bores are set as greater than the syringe needle cylindrical again less than syringe needle flange 5 external diameters.Hollow jackscrew 4 is sleeved on the syringe needle 1, and hollow jackscrew 4 is connected with sleeve 6 threaded one ends, cover friction sleeve 7 and be connected with gland 9 threaded one ends with external screw thread in sleeve 6 other ends.The middle part of said friction sleeve 7 cylindricals is provided with undercut 8; Undercut 8 one sides are that fine thread is connected with sleeve 6 female threads; Opposite side is and the close-fitting circular cone friction sleeve 10 of gland 9 endoporus; Its circular cone friction sleeve 10 increases elastic five equilibrium pintongs body (see figure 2), friction sleeve 7 and needle tubing 2 sockets for cutting apart to process.The outer round surface of said sleeve 6 and gland 9 is configured to knurled surface 11 and 12, constitutes medication injections syringe needle fastener.
The material of sleeve 6, gland 9, hollow jackscrew 4 is rustless steel, and the decorative chromium layer is established on the surface.The material of friction sleeve 7 is the engineering plastics of anti-retort sterilization.
Operational approach
Friction sleeve 7 sleeve 6 female threads of packing into are fastening, and gland 9 and hollow jackscrew 4 dextrorotation screw thread 1-2 button respectively are threaded in sleeve 6 two ends, assembling syringe needle 1, needle tubing 2 and push rod 3.With hollow jackscrew 4, sleeve 6, and the assembly of gland 9 be enclosed within on the needle tubing 2; And make needle tubing 2 bottom surfaces be close to the screw thread end face that sleeve 6 links to each other with hollow jackscrew 4; Firmly dextrorotation gland 9 until sleeve 6 through friction sleeve 7 and needle tubing 2 be connected firmly, the hollow jackscrew 4 of dextrorotation compresses syringe needle flange 5 again, in case syringe needle 1 comes off.Needle tubing is packed into behind the injection medicament, just can carry out high-pressure injection by the propeller of special use or the vertical extraordinary thrust of free-hand generation, and injection finishes, and contrary spinning lid 9 and hollow jackscrew 3-4 button just can be extracted syringe out, carry out next time and inject.
