Description
Technical field
The present invention relates to a kind of checkout equipment, especially relate to a kind of checkout equipment of transfusion device.
Background technology
Aseptic apparatus full name is Disposable Aseptic Medical Instruments, refers to aseptic, apyrogeneity, through being up to the standards, the medicine equipment of disposable direct use before the deadline.Disposable infusion set belongs to aseptic apparatus.
Aseptic medical equipment automated arm industry is flourish in recent years, but present stage aseptic medical equipment enterprise automaticity also very low, its automaticity also have very large room for promotion.Such as, the production assembling process of disposable infusion set, is still manual operation substantially, and its main cause is owing to being flexiplast part by dress group new product, be difficult to realize automatic Composition than conventional products, also do not realize so far the whole-process automatic assembling of disposable infusion set.But market development megatrend is that medical device industry is generally in the urgent need to technological innovation, transition upgrading to change labor-intensive present situation, also be that the research and development of whole-process automatic package technique are imperative, thereby the designing and developing of the Automatic Measurement Technique of disposable transfusion device and device, promoting, its automatic Composition implementer face is very important.Disposable infusion set impermeability and aeration are for must examine performance, but during enterprise produces at present, this performance, still taking manual detection as main, is difficult to adapt to automated production requirement.The Chinese patent that is CN201795901U as publication number discloses a kind of air leakage detector for infusion apparatus, can be effective to solve problem convenient, the gas leakage of fast detecting transfusion device.Its technical scheme is: comprise glass tube, needle tubing and air valve, needle tubing is placed in glass tube, glass tube inner aqueous layer top is air layer, needle tubing is suitable for reading inserts in air layer, one end, glass tube bottom is connected with source of the gas, the other end is connected with air valve bottom by skirt, air valve structure is, valve gap is equipped with through connector in valve body top, bonnet lower is equipped with spool in valve body, and valve inner hollow forms inwall gas circuit, has outlet on valve gap, the spring being contained in valve body is equipped with in spool lower end, and valve body lower portion is linked together by connector and skirt.When use, measured piece pack into valve gap suitable for reading in, depress measured piece, its gas port is connected with spool, gas flows through spool side opening and arrives gas port from bottom, seal valve gap outlet, glass tube upper end and source of the gas formation pressure reduction if assembly leaks gas, because needle tubing is suitable for reading in air simultaneously, therefore dividing with bubbling form, gas enters to manage top, now can conveniently check gas leakage situation: if assembly is air tight, upper and lower pressure reduction is zero, and the water surface remains static; After having leaked hunting equally, due to the effect of spring, on spool, move, O-ring seal seals spool side opening and whole inwall gas circuit, and system is without pressure reduction, and the water surface also remains static.But this technical scheme is by operator's visual inspection bubbling situation, and whether device itself have problem, is also not easy observedly, therefore, uses this device to detect also unreliable, and automaticity is not high yet, and testing process meeting consuming time is long.
Summary of the invention
The present invention solves the technical matterss such as the existing detection of prior art is unreliable, automaticity is not high, testing process length consuming time, and a kind of automaticity is high, easy to detect, have System self-test function kind transfusion device impermeability/aeration automatic detection device and detection method thereof are provided.
Above-mentioned technical matters of the present invention is mainly solved by following technical proposals: a kind of transfusion device impermeability/aeration automatic detection device, it is characterized in that, it comprises a source of the gas and an air inlet pipeline being connected with source of the gas, air inlet pipeline is provided with source of the gas cleaning device, on air inlet pipeline after source of the gas clearer, be provided with in turn pressure governor, pressure and flow judging device, the end of air inlet pipeline is provided with one for connecting the interface of transfusion device input end, this interface side is provided with a position sensor, the signal output part of this position sensor is connected with a controller, this controller is connected with alarming device with described pressure and flow judging device respectively by signal circuit.Using this device when transfusion device is detected, by the entrance point insertion interface of transfusion device, now position sensor can picked up signal, and controller knows that by this signal transfusion device is in place, and detects.The entrance point of transfusion device is larger, and endpiece is less.Therefore, can think, the air-flow size tool that the situation of the endpiece of transfusion device reaches when detecting has a direct impact.The in the situation that of constant air pressure, in the time that endpiece stops up, the air-flow detecting can reduce; When any position before endpiece and endpiece leaks air, the air-flow detecting will increase.But, in the time there is the inaccurate problem of air pressure in device itself, this detection also can be forbidden, so the present invention also provides the pre-detection structure to device, be after source of the gas clearer is processed gases at high pressure, be adjusted to transfusion device authorized pressure by pressure governor, and judge that by pressure and flow judging device whether pressure is suitable, if information warning appears in improper system, operator just can overhaul device immediately, can't therefore occur measured piece to detect improperly.
As preferably, described interface is provided with a pressure valve, and the leading end of this pressure valve is connected with air inlet pipeline, and outlet side is provided with one for connecting the mouth that is tightly connected of measured piece.Pressure valve is opened in the time that air pressure reaches the appropriate value of detection, when source of the gas is closed or when air pressure reduces to certain value, pressure valve closes, extraneous gas can not flowed back in device, because of a little these devices at equipment after this pressure valve, just can not polluted by outside air, also can, because of detection, not bring pollution to measured piece.
As preferably, the outside of the described mouth that is tightly connected is provided with a gas leakage test chamber, this gas leakage test chamber is provided with a seal insert coaxial with the described mouth that is tightly connected, gas leakage test chamber is provided with an escape pipe, this escape pipe is provided with a pneumatic detector, and the signal circuit of pneumatic detector is connected with described controller.Be tightly connected mouth with after being repeatedly connected of measured piece, there will be the bad problem of sealing, leak air, will impact the accuracy detecting.In this programme, the entrance point of measured piece first passes through seal insert, then is connected with the mouth that is tightly connected, and between seal insert and measured piece, is tightly connected, in the time that the sealing being tightly connected between mouth and measured piece goes wrong, gas flows out, and major part all or wherein flows out from escape pipe, in the time that pneumatic detector has detected air-flow, illustrating is tightly connected has gas leakage between mouth and measured piece, to controller discovery signals, controller, by alarming device prompting operation person, stops detecting.
As preferably, described controller is provided with counting unit, and controller is connected with an electronic console.In the time that each position sensor sends measured piece and puts signal in place to controller, counter is about to counting and adds 1, and shows by electronic console, knows the number of packages of measurement with handled easily person.
