Abstract
The utility model relates to an air leakage detector for an infusion device, which is composed of an air nozzle, a valve body, a push rod, a spring, and a pressure detection meter. The air nozzle is connected and fixed with the valve body through bolts; the inner part of the valve body is provided with the push rod; a cavity is arranged between the push rod and the valve body, and the middle of the push rod is provided with a centre hole. While in use, the infusion device is inserted into the hole end, and the infusion device can be checked whether the air leakage is generated or not through the pressure detection meter. The ideal air leakage detector for an infusion device of the utility model which can not cause the pollution to the infusion device has the advantages of simple structure, convenient operation, fast detection speed, and high quality.
Description
The utility model relates to a kind of pick-up unit of transfusion device sealing, specifically a kind of transfusion device gas leak detector.
At present, the detection of transfusion device sealing generally is with transfusion device inflation, sealing, puts into water and sees whether emit bubble, carries out the detection of even part micro-leakage, and this method troublesome poeration detects out of true, and easily causes the pollution of transfusion device; Usefulness one three-way pipe that also has connects transfusion device conehead, tensimeter and pneumatic supply respectively, after inflation is stable, observes the tensimeter indication, to detect whether micro-leakage, low, the troublesome poeration of this method detection efficiency is arranged.Till the present, also there is not special transfusion device gas leak detector.
The purpose of this utility model is exactly in order to provide a kind of simple in structure, easy to operate, the transfusion device gas leak detector that detection speed is fast, quality is high.
For achieving the above object, a kind of transfusion device gas leak detector, it is characterized in that it is by valve, valve body, push rod, spring, the pressure detection table is formed, valve and valve body are connected and fixed by bolt, be provided with a push rod and air chamber in the valve body, be provided with spring in the air chamber, both ends of the spring contacts with push rod with valve respectively, push rod is provided with a ring groove, forms a cavity with valve interior wall, and is communicated with by through hole on the body wall and pressure detection table, the two ends of ring groove are provided with O-ring seal on the push rod, be provided with a center pit in the middle of the push rod, the inner end is provided with through hole, is communicated with cavity.
When the utility model uses, valve is communicated with pneumatic supply, the gas that certain pressure is arranged in the air chamber, the transfusion device conehead inserts the center pit openend, promotes push rod and moves inwards, enter gas in cavity and the transfusion device, push rod can reset under spring action, cavity and transfusion device sealing after this, and whether observe pressure from the pressure detection table stable, just can detect transfusion device and whether leak gas, check its sealing property.The utility model also is suitable for detecting syringe whether micro-leakage takes place.
The utility model is simple in structure, and is easy to operate, and detection is accurate, speed is fast, is a kind of desirable transfusion device gas leak detector.
Below in conjunction with accompanying drawing the utility model embodiment is described further:
Fig. 1 is the utility model structural representation, also is the synoptic diagram of embodiment.
As can be seen from Figure 1, a kind of transfusion device gas leak detector, it is by valve 1, valve body 9, spring 10, pressure detection table 11, push rod 13 compositions such as grade, be connected and fixed by bolt 2 between valve 1 and the valve body 9, and be provided with sealing gasket 3 in the centre, the mouth mouth of valve 1 connects pneumatic supply, be provided with push rod 13 and air chamber 4 in the valve body 9, push rod 13 can be left in valve body 9, move right, push rod 13 1 ends are provided with a boss, it can match with the step established in the valve body 9, so that push rod 13 can not slided valve body 9, establish spring 10 in the air chamber 4, its two ends contact with push rod 13 1 inner faces with valve 1 inboard respectively, so that push rod has the effect of an outside power all the time, so that it in time resets.Push rod 13 is provided with a ring groove, itself and valve interior wall form a cavity 6, cavity 6 is communicated with by a through hole 12 and the pressure detection table 11 that valve body 9 is provided with, the two ends of ring groove are provided with sealing gasket 5,8 on the push rod 13, to guarantee that cavity keeps one's end up, be provided with a center pit 14 in the middle of the push rod 13, its inner end is provided with a through hole 7, by through hole 7, center pit 14 is communicated with cavity 6, and the openend of center pit 14 is tapered, so that be connected sealing with the conehead wringing fit of transfusion device, whether like this, just can be observed transfusion device from the pressure detection table leaks gas.
Use this transfusion device gas leak detector, valve 1 is connected with extraneous snorkel, the gas that certain pressure is arranged in the air chamber 4, during detection, the transfusion device conehead is inserted the openend of the center pit 14 of push rod 13, promoting push rod 13 moves inwards, enter the gas of certain air pressure until cavity 6, center pit 14 and detected transfusion device, then stop to promote, push rod 13 grades reset under spring 10 effects, whether the pressure of observing pressure detection table 11 this moment is stable, just can judge exactly whether transfusion device micro-leakage takes place, and whether sealing is intact.Then dial transfusion device down, carry out next one inspection, checking only needs one to insert one group, easy to operate, detects the quality height, and speed is fast, does not pollute transfusion device, is a kind of desirable transfusion device gas leak detector.
Claims (2)
1, a kind of transfusion device gas leak detector, it is characterized in that it is made up of valve, valve body, push rod, spring, pressure detection table, valve and valve body are connected and fixed by bolt, be provided with a push rod and an air chamber in the valve body, be provided with spring in the air chamber, both ends of the spring contacts with push rod with valve respectively, push rod is provided with a ring groove, form a cavity with valve interior wall, and by through hole on the body wall and the connection of pressure detection table, the two ends of ring groove are provided with O-ring seal on the push rod, are provided with a center pit in the middle of the push rod, the inner end is provided with through hole, is communicated with cavity.
