Abstract
The utility model belongs to the technical field of medical instrument tools, and particularly relates to an air detector for a disposable intravenous infusion needle. The air detector for the disposable intravenous infusion needle comprises an upper module and a lower module. An isolating membrane is placed between the upper module and the lower module in a clamped mode. An air barrel is placed in the lower module and is connected with an air inlet valve through an air inlet pipe, and an air inlet source pipe line is connected to the air inlet valve. A pressurizing bag is placed inside the upper module and is connected with a detecting air pipe which is connected with a multi-head connecting part, and the multi-head connecting part is connected with a pressure gage through an air outlet pipe and is connected with a product detecting connector. According to the air detector for the disposable intravenous infusion needle, testing pressure can meet regulated demands, the testing pressure cannot be too large to damage a product, and meanwhile secondary pollution of the product is reduced.
Description
Technical field
This utility model medical apparatus and instruments belongs to the apparatus technical field, relates in particular to a kind of disposable use venoclysis needle usefulness gas and examines instrument.
Background technology
Disposable use venoclysis needle is the hospital transfusion apparatus of using always, and disposable use venous transfusion is directed to that its sealing and pipeline and syringe needle be whether unimpeded to have certain requirement.And at present, when manufacturing disposable use venoclysis needle, all be to have adopted manually to operate for the conventional method of its detection.And, check its air-tightness and checking the venous transfusion needle tract and whether syringe needle all is separately to detect test in the smoothness.Thus, the time that makes whole testing process spend is longer, and need carry out two procedures, and is cumbersome for whole testing process, is easy to generate error.And, in testing process, be easy to disposable use venoclysis needle is caused damage or causes secondary pollution.
Summary of the invention
The purpose of this utility model is to solve above-described technical problem, provides a kind of disposable use venoclysis needle usefulness gas to examine instrument, and its technical scheme is as follows:
A kind of disposable use venoclysis needle usefulness gas is examined instrument, and described disposable use venoclysis needle usefulness gas inspection instrument comprises upper module and lower module, is gripped with isolating membrane between described upper module and the lower module; Be provided with tympanites in the described lower module, described tympanites is connected with intake valve by air inlet pipe, and described intake valve is connected with air inlet source capsule road; Be provided with pressurized capsule in the described upper module, described pressurized capsule is connected with the detection trachea, and described detection trachea is connected with the bull connector, and described bull connector is connected with Pressure gauge by escape pipe, and described bull connector is connected with the product detection tabs.
Optimal way is that described isolating membrane is elastic film.
Optimal way is to be provided with check-valves between described pressurized capsule and the detection trachea.
Optimal way is to be provided with pressure regulator valve in the described pressurized capsule.
The disposable use venoclysis needle usefulness gas that this utility model provides is examined instrument, when in use, at first an end of product is connected with the product detection tabs.Check the sealing property of product earlier, earlier the other end of product is sealed with hands.Open intake valve, make clean compressed gas from air inlet source capsule road in air inlet pipe enters into tympanites.Thereby make tympanites expand, isolating membrane is gone up on the tympanites top, thereby makes the pressurized capsule pressurized.Gas pressurized in the pressurized capsule is discharged to enter into and is detected in the trachea.Gas enters into Pressure gauge and product by detecting respectively after trachea enters into the bull connector.Gas enters in the product and hunts leak, and Pressure gauge shows detected pressures.Stop the several seconds, gauge hand does not fall after rise, illustrates that the product adaptation is good, falls after rise as pointer, and product gas leakage is described.
After the sealing property of product has detected, begin to detect its smoothness.After the stop several seconds checked out sealing, an openhanded end of opening the product sealing if gauge hand falls after rise, illustrated that product cavity is unimpeded; Do not fall after rise as pointer, illustrate that product cavity stops up.
Isolating membrane described in the utility model is elastic film.Having certain elastic isolating membrane can better transmit pressure, makes that the transmission of pressure is more responsive, more is conducive to detect.
Be provided with check-valves between pressurized capsule described in the utility model and the detection trachea.Make that in the sealing property of testing product, gas can oppositely not enter in the pressurized capsule, detect trouble thereby cause.
Be provided with pressure regulator valve in the pressurized capsule described in the utility model.Can well adjust the pressure in the pressurized capsule, make it reasonably check in the pressure limit, the protection product is unlikely to be subjected to excessive pressure and occurs damaging.
When this utility model detects disposable use venoclysis needle inner chamber, the gas that enters is the quantitative interior air of clean production environment, to guarantee constant detected pressures, both guaranteed that test pressure reached the requirement of regulation, do not make again that pressure is excessive to cause damage to product, reduce the secondary pollution of product simultaneously.

The specific embodiment
Specify embodiment below in conjunction with Fig. 1:
A kind of disposable use venoclysis needle usefulness gas is examined instrument, and described disposable use venoclysis needle usefulness gas inspection instrument comprises upper module 1 and lower module 2, is gripped with isolating membrane 3 between described upper module 1 and the lower module 2; Be provided with tympanites 4, described enraged 4 in the described lower module 2 and be connected with intake valve 6 by air inlet pipe 5, described intake valve 6 is connected with air inlet source capsule road 7; Be provided with pressurized capsule 8 in the described upper module 1, described pressurized capsule 8 is connected with and detects trachea 9, and described detection trachea 9 is connected with bull connector 10, and described bull connector 10 is connected with Pressure gauge 12 by escape pipe 11, and described bull connector 10 is connected with product detection tabs 13.
Optimal way is that described isolating membrane 3 is elastic film.
Optimal way is to be provided with check-valves 14 between described pressurized capsule 8 and the detection trachea 9.
Optimal way is to be provided with pressure regulator valve 15 in the described pressurized capsule 8.
The disposable use venoclysis needle usefulness gas that this utility model provides is examined instrument, when in use, at first an end of product is connected with the product detection tabs.Check the sealing property of product earlier, earlier the other end of product is sealed with hands.Open intake valve, make clean compressed gas from air inlet source capsule road in air inlet pipe enters into tympanites.Thereby make tympanites expand, isolating membrane is gone up on the tympanites top, thereby makes the pressurized capsule pressurized.Gas pressurized in the pressurized capsule is discharged to enter into and is detected in the trachea.Gas enters into Pressure gauge and product by detecting respectively after trachea enters into the bull connector.Gas enters in the product and hunts leak, and Pressure gauge shows detected pressures.Stop the several seconds, gauge hand does not fall after rise, illustrates that the product adaptation is good, falls after rise as pointer, and product gas leakage is described.
