"Be used once on the throw, true is a pity! The"

"The bulk of catheter, radio frequency cutter head, is of solid, very good to cleaning. 1.5 million yuan to a tube wit h once and throw away, I really is a pity." A a of well-known Department of Cardiology, director of the physician of the a top three the hospital s of the the provincial capital, lift the the current high waste of brought about by by the the "one-off" Using of the value medical consumables is helpless face:

Imports of by the intestinal stapling 2800-4000 yuan / month, made ??in China 2200-2800 yuan / month, The the advantages of of adopt the intestinal tract stapling is the gap is uniform, is not easy to spondylolisthesis, on while the before the are hand-suture. "Provincial Department of Human, which makes it easy for the, can be have their advantages and disadvantages, there are also the were gone up, after the went of the nail, the individual nails leakage down."Gauze bandage

The have to use the of narcotic respiratory rib piping by the each cases of of surgery under general anesthesia, a set of more than 800 yuan, of the large foreign are scrub after disinfection repeated use, you can use many times, and the in some hospitals of the domestic but it is one-time use.

And then there are new out of the a ultrasonic scalpel, a cutter head more than 2000 yuan, proper use of funds with 5 times or even more than 10 times also no problem, can be "one-off the the requirements of of the use the", Querang the surgeon had no choice but pay to act in according to regulations . "

According to to the physician presentations of the, director of Cardiology of the a hospital in provincial, the cardiac imaging surgery, and with of the catheter is are a one-time, there are No. Ⅰ tube, the of the points of the Ⅱ No. tube, and sometimes after the the an is opened and found that is inappropriate, needs to be replaced the with the other Model, this situation is very common. However, due to the requirements of &qu ot;one-time use", the If the Zhezhi is already open tube the same day do not have access, Although it is new, but Dispose of in Press the "the provisions of" to can only be.plain catgut suture

The Honourable director of the physician are of the opinion that the that the, the same is the the use of "one-off", domestic, the foreign countries is also two different things. Due to the scientific and technological level, labor force price and other factors, in a foreign country "repair the a not as good as to buy a", while China s current the vast majority of high value single use consumables and or a file rely on to a Windows imports of, in foreign countries very cheap, to the domestic it becomes is very expensive.

It is predicted that from 2003 to 2005, China s medical device market will grow by 40%, the medical plastic will continue to increase. This trend is rising, forming a hu ge potential market of medical products.

With the growing awareness of people s health, the gradual improvement of the medical insurance system, medical product requirements will be higher. In order to meet the use requirements, the necessary modification of raw materials and improve the molding process is necessary. This paper describes several polyolefin medical plastic the processing modifier technology and products forming a new process.Poliglecaprone 25

1, polyvinyl chloride (PVC)

PVC has good chemical resistance, mechanical properties and electrical properties, but its resistance to heat and light stability. By processing the modified PVC plastic, can be widely used to make storage blood bags, blood bags and blood catheters, artificial peritoneum, artificial urinary bag artificial lung, cardiac catheterization and artificial heart and other products.

PVC gl ass transition temperature (Tg) is higher, the hardness of the material, the molding process difficult. Thus, the ships are added to the PVC resin, plasticizer and other additives. At present, still in the processing phthalate, dioctyl phthalate (DOP) as a primary plasticizer [1]. DOP is a low molecular weight substances, easy migration precipitation. DOP plasticized PVC for medical tubing or container, the DOP easy precipitation mixed with liquid or blood will lead to enter the body of the DOP with liquid or blood. In order to protect the health and safety of PVC medical plastic abroad are developing toxicity lower than the DOP, the migration precipitation DOP small new plasticizer, including good health citric acid esters, higher molar mass polyester class and other polymeric plasticizer.surgical sutures types

Stabilizer in PVC processing, lead salt is toxic to blood, causing severe anemi a, even more cadmium salts; better tin salt and epoxidized soybean oil. Generally used in dissolution less the organotin appropriate, which the two mercapto Titanium octyl di-n-octyl tin (Jing tin 8831) is a non-toxic organic tin stabilizer, excellent heat resistance and transparency, but lubricity than poor. Calcium stearate (Cast) and zinc stearate (ZnSt) is a non-toxic, transparent, stabilizers, there is a good lubrication. Therefore, with a certain amount of CAST and ZnSt of make up two mercapto acid isooctyl di-n-octyl tin (tin Beijing 8831) the shortcomings of poor lubrication. Medical PVC products in the processing, the choice of the internal and external lubrication are good N, N -B the Thalidomide (EBS) bistearic and silicone oil as a lubricant, a small amount of ACR as a processing aid, help to improve the surface of the PVC plastic quality.
