Abstract
The invention discloses a medical instrument, belongs to the technical field of appliances, and particularly relates to an air detector for disposable venous transfusion needles. The air detector for the disposable venous transfusion needles comprises an upper module and a lower module; an isolation film is sandwiched between the upper module and the lower module; an air drum is arranged in the lower module and is connected with an air inlet valve by an air inlet pipe, and the air inlet valve is connected with an air inlet source pipeline; and a pressurizing bag is arranged in the upper module and is connected with a detecting air pipe, and a multi-head connector is connected with the detecting air pipe, is connected with a pressure gauge by an air outlet pipe and is connected with a product detecting joint. The air detector has the advantages that the test pressure can meet specified requirements assuredly, products are prevented from being damaged by excessively high pressure, and secondary pollution of the products can be reduced.
Description
Technical field
Medicine equipment of the present invention belongs to the apparatus technical field, relates in particular to a kind of disposable use intravenous infusion needle usefulness gas and examines instrument.
Background technology
Disposable use intravenous infusion 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 intravenous infusion needle, all be to have adopted manually to operate for the conventional method of its detection.And, check its impermeability 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 intravenous infusion needle is caused damage or causes secondary pollution.
Summary of the invention
The objective of the invention is to solve above-described technical matters, provide a kind of disposable use intravenous infusion needle usefulness gas to examine instrument, its technical scheme is as follows:
A kind of disposable use intravenous infusion needle usefulness gas is examined instrument, and described disposable use intravenous infusion needle usefulness gas inspection instrument comprises upper module and lower module, is gripped with barrier film between described upper module and the lower module; Be provided with tympanites in the described lower module, described tympanites is connected with gas admittance valve by draft tube, and described gas admittance 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 tracheae, and described detection tracheae is connected with the bull web member, and described bull web member is connected with tensimeter by escape pipe, and described bull web member is connected with the product detection tabs.
Optimal way is that described barrier film is elastic film.
Optimal way is to be provided with non-return valve between described pressurized capsule and the detection tracheae.
Optimal way is to be provided with pressure regulator valve in the described pressurized capsule.
Disposable use intravenous infusion needle usefulness gas provided by the invention 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 hand.Open gas admittance valve, make clean compressed gas from air inlet source capsule road in draft tube enters into tympanites.Thereby make tympanites expand, barrier film 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 tracheae.Gas enters into tensimeter and product by detecting respectively after tracheae enters into the bull web member.Gas enters in the product and hunts leak, and tensimeter 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.
Barrier film of the present invention is elastic film.Having certain flexible barrier film can better transmit pressure, makes that the transmission of pressure is more responsive, more is conducive to detect.
Be provided with non-return valve between pressurized capsule of the present invention and the detection tracheae.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 of the present invention.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 the present invention detects disposable use intravenous infusion 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.

Embodiment
Specify embodiment below in conjunction with Fig. 1:
A kind of disposable use intravenous infusion needle usefulness gas is examined instrument, and described disposable use intravenous infusion needle usefulness gas inspection instrument comprises upper module 1 and lower module 2, is gripped with barrier film 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 gas admittance valve 6 by draft tube 5, described gas admittance 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 tracheae 9, and described detection tracheae 9 is connected with bull web member 10, and described bull web member 10 is connected with tensimeter 12 by escape pipe 11, and described bull web member 10 is connected with product detection tabs 13.
Optimal way is that described barrier film 3 is elastic film.
Optimal way is to be provided with non-return valve 14 between described pressurized capsule 8 and the detection tracheae 9.
Optimal way is to be provided with pressure regulator valve 15 in the described pressurized capsule 8.
Disposable use intravenous infusion needle usefulness gas provided by the invention 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 hand.Open gas admittance valve, make clean compressed gas from air inlet source capsule road in draft tube enters into tympanites.Thereby make tympanites expand, barrier film 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 tracheae.Gas enters into tensimeter and product by detecting respectively after tracheae enters into the bull web member.Gas enters in the product and hunts leak, and tensimeter 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.
