Description

A kind of testing agency of medical needle air-tightness
Technical field
The utility model belongs to technical field of medical equipment, is related to a kind of testing agency of medical needle air-tightness.
Background technology
Medical needle includes needle tubing and needle stand, and in production, in order to avoid needle contact to pollutant, needle tubing and needle stand are Assembled by the production line of automatic assembling, gluing first is carried out to the end of needle tubing before assembling, then by the way that needle tubing is inserted It is connected on needle stand and glued fixed by glue.Gluing is uneven because of situations such as existing, and can cause the connection of needle tubing and needle stand Place there may be the situation of blow-by, it is therefore desirable to needs first to detect syringe needle when by needle fits to syringe, with Filter out and seal syringe needle not in place.
Detection currently for syringe needle head seal is generally realized using pressure sensor, such as Chinese patent literature is public A kind of medical needle air-tightness detection device opened【Application number 201210148183.2】, including workbench, it is arranged on workbench On stent, the cavity volumes provided with multiple splendid attire syringe needles in stent;It is provided with directly over stent and moves up dynamic model, upper driving dress Put, pressure sensor;Workbench bottom is provided with and moves down dynamic model, lower drive device;Upper drive device control moves up dynamic model and vertically moved It is dynamic;It is vertically movable that lower drive device control moves down dynamic model;Move up in dynamic model and be provided with gas inlet tube;Gas inlet tube be provided with it is multiple with Its gas outlet tube communicated;Move down dynamic model and be provided with multiple plugs;Workbench is provided with and is used in conjunction with each other with plug, cavity volume Through hole;Mutually gas is connected pressure sensor with gas inlet tube.Although the change of air pressure can be detected by pressure sensor, It is defective that syringe needle air-tightness is can only obtain during using the test mode, but which specific position can not be obtained air-tightness occurs asking Topic;This method needs the larger change that can accurately just detect air pressure of air pressure to being inputted in syringe needle simultaneously, it is therefore desirable to Charger is larger, while also needs to be used cooperatively with apparatus such as computer, and cost is higher.
The content of the invention
The purpose of this utility model is above mentioned problem be present for existing technology, it is proposed that a kind of medical needle air-tightness Testing agency, the technical problem that the utility model solves is that the airtight of needle tubing and needle stand can be detected by way of low cost Property.
The purpose of this utility model can be realized by following technical proposal:
A kind of testing agency of medical needle air-tightness, including frame, it is characterised in that the frame is provided with lifting Frame, the crane include upper table, lower table and the connecting rod of connection upper table and lower table, the upper work The lift cylinder of upper table oscilaltion can be driven by being provided between platform and frame, be fixed with valve on the upper table, institute The outlet mouth down for stating valve is set, and the air inlet of the valve is connected with a gas tube, and liter is additionally provided with the upper table Plate is dropped, is connected with the clamping jaw that can clamp syringe needle on the lifter plate, the clamping jaw is located at the underface of valve, the lifter plate energy Moved up and down with respect to upper table and the needle stand of syringe needle is connected with valve, be fixed with the lower table flexible Silica gel block, the spliced eye for the needle tubing head insertion that can cause syringe needle is provided with the silica gel block, is located at silicon on the lower table Blob of viscose both sides are respectively equipped with gripping block, and when the clamping jaw clamps, two pieces of gripping blocks can clamp silica gel block and cause spliced eye Tighten, water tank is fixed with immediately below the crane.
Distilled water is inoculated with water tank, in detection, syringe needle is positioned by fixed mount, and fixed mount is transported between clamping jaw, this When syringe needle needle tubing head insertion silica gel block spliced eye in, by clamping jaw by fixed mount clamping and positioning, at the same, two pieces clamping Block clamps silica gel block and so that spliced eye tightens, then needle tubing head seal can be passed through and lift lifting by spliced eye after locking Plate causes needle stand to be connected with valve, by gas tube toward inflating in needle stand, because needle tubing head is sealed, therefore has in syringe needle Certain air pressure, immersed being moved down by lift cylinder crane in water tank, treat that water is immersed in the junction of needle tubing and needle stand In after, if in water bubble-free produce, as syringe needle airtight sexual satisfaction requirement, if emerged in water with bubble, then it represents that There is problem in the air-tightness of syringe needle, airtight sex chromosome mosaicism occur by observing which position of the position i.e. can be known of bubble;This structure Only there need to be no problem by observing bubble i.e. can be known air-tightness, and it is relatively low without high-pressure pump and apparatus such as computer, cost.
In the testing agency of above-mentioned medical needle air-tightness, the clamping jaw includes clamping cylinder and two pieces of fixture blocks, institute State clamping cylinder to be fixed on lifter plate, two cylinder arms of the clamping cylinder are respectively and fixedly provided with clamping bar, the upper table On be provided with two bar holes, two clamping bars pass through corresponding bar hole, i.e. two clamping bars are located in two respectively In individual bar hole, two fixture blocks are separately fixed on two clamping bars, and the lower end of two clamping bars clamps with two pieces respectively Block is fixed.Clamping cylinder can make it that two clamping bars are relatively close or remote, therefore two pieces of fixture blocks can clamp syringe needle, while two Block gripping block can clamp silica gel block, realize synchronous clamping and the release of clamping jaw and gripping block.
In the testing agency of above-mentioned medical needle air-tightness, the longitudinal section of the silica gel block is trapezoidal, described in two pieces Gripping block reclines with the both sides inclined-plane of silica gel block respectively.The structure can cause the upper port of silica gel block spliced eye to shrink tighter, From the sealing that can guarantee that to needle tubing head.
In the testing agency of above-mentioned medical needle air-tightness, some through holes are provided with the lower table.It will rise Drop frame is put into through hole when in water tank and can reduce the resistance of water so that crane easily submerged or can lift from water.
In the testing agency of above-mentioned medical needle air-tightness, air-heater, the hot blast are further fixed in the frame Machine is towards the underface of clamping jaw.The moisture on syringe needle is blown open by air-heater after detection terminates so that under syringe needle can enter One step assembly process.
Compared with prior art, the testing agency of this medical needle air-tightness have can quick detection syringe needle air-tightness and It is simple in construction, lower-cost advantage.
