The device comprises a working table and a fixed mould arranged on the working table, wherein the fixed mould is provided with a plurality of accommodating cavities for accommodating the needle heads; an upper moving mould, an upper driving device and a pressure sensor are arranged above the fixed mould; a lower moving mould and a lower driving device are arranged at the bottom part of the working table; an input air pipe is arranged in the upper moving mould; the input air pipe is provided with a plurality of output air pipes communicating with the input air pipe; the lower moving mould is provided with a plurality of plugs; the working table is provided with through holes used in cooperation with the plugs and the accommodating cavities; and the pressure sensor is connected with the input air pipe in a mode of air connection. According to the air-tightness detection device, the lower ends of the needle heads are plugged by the plugs and sealing rings, the air is blown into the needle heads from the upper ends of the needle heads through the input air pipe and the output air pipes, pressure is remained, change of pressure quantity of the input air pipe is detected by the pressure sensor, and a purpose of detecting the air tightness of the medical needle heads is achieved. The operation is simple, convenient and reliable, the detecting time is shortened, and the cost is reduced.

Description

A kind of medical needle air-tightness detection device
Technical field
The utility model relates to a kind of air-tightness detection device, relates in particular to a kind of medical needle air-tightness detection device, belongs to welding technology field.
Background technology
Medical needle comprises the pullover and syringe needle cover for seat of needle holder, and said needle holder is pullover to be integral through Vibration Welding with the syringe needle cover for seat, and their centers are that connect and coaxial through hole; Impermeability for after guaranteeing that needle holder is pullover and welding together with the syringe needle cover for seat guarantees welding quality, needs the impermeability of syringe needle is detected; And the bubble-tight device of present existing detection; Mostly complex structure, and cost is high, and operating of having is also cumbersome; Be inappropriate for the bubble-tight detection of medical needle, therefore need have proposed a kind of special-purpose medical needle air-tightness detection device.
The utility model content
The utility model purpose is to provide a kind of simple in structure for the deficiency that overcomes prior art, a kind of medical needle air-tightness detection device that reliably is suitable for the detection of medical needle impermeability easy to detect.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of medical needle air-tightness detection device, comprise worktable, and be arranged on the fixed die on the worktable, be provided with the cavity volume of a plurality of splendid attire syringe needles in the said fixed die; Be provided with directly over the said fixed die and move mould, go up drive unit, pressure transducer; Said worktable bottom is provided with and moves down dynamic model, following drive unit; Moving mould on the said upward driving device controls vertically moves; Said driving device controls down moves down dynamic model and vertically moves; Said going up in the mobile mould is provided with gas inlet tube; Said gas inlet tube is provided with a plurality of gas outlet tubes that communicate with it; The said dynamic model that moves down is provided with a plurality of plugs; Said worktable is provided with the through hole that cooperatively interacts and use with plug, cavity volume; Said pressure transducer and gas inlet tube gas connection mutually.
Preferably, said plug top is provided with O-ring seal.
Preferably, said upper and lower drive unit is a telescopic cylinder.
Preferably, the quantity of said cavity volume, gas outlet tube, plug equates.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
A kind of medical needle air-tightness detection device of the utility model scheme; Block the lower end of syringe needle through plug, O-ring seal, blow pressurize from the syringe needle upper end to syringe needle is inner through gas inlet tube, gas outlet tube; And then detect the variation of the amount of gas pressure of gas inlet tube through pressure transducer; Detect the bubble-tight purpose of medical needle thereby reach, simple to operate and convenient and reliable, shorten detection time and reduced cost.
Description of drawings
Below in conjunction with accompanying drawing the utility model technical scheme is described further:
Accompanying drawing 1 is the structural representation of medical needle;
Accompanying drawing 2 is the structural representation of the medical needle air-tightness detection device of the utility model;
Wherein: 1, worktable; 2, fixed die; 3, cavity volume; 4, upward move mould; 5, move down dynamic model; 6, gas inlet tube; 7, gas outlet tube; 8, plug; 9, O-ring seal; 10, through hole; 11, telescopic cylinder; 12, syringe needle; 13, needle holder is pullover; 14, syringe needle cover for seat.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
Medical needle 12 shown in accompanying drawing 1 comprises needle holder pullover 13 and syringe needle cover for seat 14, and said needle holder pullover 13 and syringe needle cover for seat 14 are integral through Vibration Welding, and their centers are that connect and coaxial through hole.
Like a kind of medical needle air-tightness detection device of accompanying drawing 2 described the utility model, comprise worktable 1, be arranged on the fixed die 2 on the worktable 1, be provided with the cavity volume 3 of a plurality of splendid attire syringe needles 12 in the said fixed die 2; Be provided with directly over the said fixed die 2 and move mould 4, go up drive unit, pressure transducer (not shown); Said worktable 1 bottom is provided with and moves down dynamic model 5, following drive unit; Moving mould 4 on the said upward driving device controls vertically moves; Said driving device controls down moves down dynamic model 5 and vertically moves; Said going up in the mobile mould 4 is provided with gas inlet tube 6; Said gas inlet tube 6 is provided with a plurality of gas outlet tubes that communicate with it 7; The said dynamic model 5 that moves down is provided with a plurality of plugs 8; The top of said plug 8 is provided with O-ring seal 9; Said worktable 1 is provided with the through hole 10 that cooperatively interacts and use with plug 8, cavity volume 3; Said pressure transducer and gas inlet tube 6 gas connection mutually; Said upper and lower drive unit is a telescopic cylinder 11; The quantity of said cavity volume 3, gas outlet tube 7, plug 8 equates.
During detection, moved down dynamic model 5 before this and moved up, and moved down the plug 8 that has O-ring seal 9 on the dynamic model 5 and insert the hole, bottom of blocking syringe needle cover for seat 14 in the through hole 10 through telescopic cylinder 11; Be to go up mobile mould 4 to move down through telescopic cylinder 11 again, the hole of gas outlet tube 7 is inserted in the needle holder pullover 13, and the 3rd is to ventilate in gas inlet tube 6 through the air pump (not shown); Gas gets in the syringe needles 12 through gas outlet tube 7, stops to blow pressurize after reaching certain amount of gas pressure; Change through baroceptor detected gas pressure at last; Thereby detect the impermeability of syringe needle 12, simple in structure, operation is very simple and convenient also.
