continuing on this problem.. Is it possible to seal PE bags to PET sheets? or is that completely impossible? thank you in advance Cheers, Jay

Thank you all for your quick reply and information Well, I can't give too much details, as no patent has been applied for yet. This is as much I can give: - intended to be a disposable product - the bag should have a certain strength and flexibility, but must also easily be punctured (cannot...

ow I forgot to mention that the thickness of the PP is about 0.05mm thick

Hello there! I have a question and I found a similar question before, but not exactly answering my question. So, I'm hoping you guys can help me. I want to glue a PE-bag to a PP surface. [I choose to use a PE-bag because it is more flexible than a PP-bag? (correct me if I'm wrong)] I think it...

it will be inside the body just distance measurement

hmmm I purely want to measure distance during a laparoscopic surgery (CO2-gas in the abdominal area). So that is why I can't use 3-7 MHz, I really need to be in the kHz range. so it is NOT ultrasonic imaging Jay

Hi the frequency that I want to use is around 40 kHz purely for distance measuring, so no harm to the human body, Low power also only a small range max of 10 cm so how big can this be? because I really want to come close about 5 mm or less in diameter. but if I use piezo? can I use it inside...

yes, it needs to go inside the human body (abdominal region) sorry but what is MFGS? Thank you for your info, I will try Thomas Register thx Jay

to buzzp: the sensor i want to use is actually for inside the body. CO2-gas environment, and soft tissue are capacitive or inductive prox sensors also suitable for that? and where can i find them. to Efp: I'm really trying to search for sensors smallers than 10 mm low power thx jay

Hi, I'm trying to find a company where I can buy small low power ultrasonic transceivers (to use in distance measurement) small as in < 10 mm - measurement of short distances tried google, but can't find anything Anybody can help me Thx in advance Jay

another thing, which frequency is suitable for not damaging the tissue?

Hi Does anybody know what kind of errors might occur if you use a ultrasonic distance measuring sensor inside the body? Especially in laparoscopic surgery (CO2-gas) Mainly does the tissue absorb the waves or something like that or directly reflect it when hitting the surface? Hope someone...

Oh yeah, sorry for that Well I want to sterilize a ultrasonic transponder, however I cannot find one which can withstand that temperature. So I was wondering how to do this Hope this helps? Jay

Hmm sorry uh I know the steps, but what I mean is how are the circuitry normally protected when they need to be sterilized? special material coating or something like that? Jay

Thx Dave, Yeah I've already contacted the hospital and they use 4 levels, cleaning by hand, ultrasonic, steam and ultraviolet So the ultrasonic transponder must undergo these steps too. Jay
