Abstract
A medical treatment injection needle head fastening device comprises a needle head, a needle tube, a push rod, a sleeve, a pressure cover, a friction sleeve and a hollow jackscrew. The center hole of the hollow jackscrew is greater than the excircle of the needle head and smaller than the external diameter of a flange of the needle head, the hollow jackscrew is installed on the needle head in a sleeved mode and connected with one end of the sleeve in a threaded mode, the friction sleeve is sleeved inside the other end of the sleeve which is connected with one end of the pressure cover in a threaded mode through external threads, and at the same time, the sleeve is connected with the friction sleeve in a threaded mode through internal threads, and the friction sleeve and the needle tube are connected in a sleeved mode. The medical treatment injection needle head fastening device is exquisite and reasonable in design, convenient and reliable to use, and simple in manufacture and easy to implement.
Description
Technical field
This utility model relates to the syringe in the medical apparatus and instruments, particularly relates to the Medical syringe needle head fastener.
Background technology
Along with people's continuous lifting of 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, the new medical skill such as beautiful+healthy, little shaping fashion beauty treatment and facial rejuvenation, ring fixed pattern liposuction aspiration are arisen at the historic moment, in many shaping and beauty projects, in the 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 usually adopts common medical syringe to be equipped with special-purpose propeller and finishes.Yet, during self-locking frictional force between injection pressure is greater than syringe needle and needle tubing on the conical contact surface, often the fault that syringe needle comes off can occur, affect normal operating.
The utility model content
The technical problems to be solved in the utility model is, provide a kind of can guarantee high-pressure injection the time syringe needle do not come off, and be the Medical syringe needle head fastener that common medical syringe is equipped with.
The technical scheme that adopts is:
The Medical syringe needle head 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, and sleeve other end inner sleeve friction sleeve also is connected with the gland threaded one end with external screw thread.
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 make.
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.
Above-mentioned sleeve and the outer round surface of gland are configured to knurled surface.
Above-mentioned hollow jackscrew is six square toes jackscrews.
This utility model deft design is reasonable, and is easy to use and reliable, makes simple.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
The Medical syringe needle head 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, and sleeve 6 other end inner sleeve friction sleeves 7 also are connected with gland 9 threaded one ends with external screw thread.The middle part of described 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) for cutting apart to make, friction sleeve 7 and needle tubing 2 sockets.The outer round surface of described sleeve 6 and gland 9 is configured to knurled surface 11 and 12, consists of the Medical syringe needle head 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.
