Abstract
The invention relates to a combination packaging bag for sterilizing and drying medical articles and methods of sterilization and dryness. The invention is characterized in that the combination packaging bag comprises an outer packaging bag and an inner packaging bag sleeved in the outer packaging bag. The methods of sterilization and dryness comprise the following steps: putting the inner packaging bag of medical articles to be sterilized into the outer packaging bag; sealing the outer packaging bag by hot pressing; putting the outer packaging bag into a sterilizing stove to sterilize through ethylene epoxide; and then heating up temperature, pumping out vacuum, and charging with nitrogen in the stove; standing for forty minutes; discharging gas, and recovering normal pressure; repeating five to ten times in a way; displacing out residual ethylene epoxide and moisture in the combination packaging bag; taking out the outer packaging bag which is sterilized, and combing and sealing the overlap section between the inner packaging bag and the outer packaging bag, thereby obtaining sterilized and dry medical articles. The invention can exclude the residue amount between the moisture and ethylene epoxide in the combination packaging bag, thereby achieving required standard, and further preventing the medical articles from invalidating due to high moisture during effective lifetime process.
Description
Technical field
The present invention relates to a kind of method that is used for the combined packaging bag sterilizing-drying of medical supplies sterilizing-drying.
Technical background
Some embedded types absorb product at present, absorbable suture for example, absorbable hemostasia materials etc. are because the characteristic of facile hydrolysis, so after these product sterilizations, not only the EO residual quantity there is exacting requirements, and moisture in the packaging bag is also had very exacting requirements, if moisture is above standard in the packing of sterilization back, then can cause product before not using packaged in the moisture hydrolysis so that product function inefficacy.In order to address this problem, then must adopt waterproof materials to pack, but the interior EO of product just can not discharge like this, causes the EO residual quantity to exceed standard.In order to solve this two problems simultaneously, then must adopt a kind of extra package method and a kind of special disinfecting and drying method that the product after sterilizing is handled, make it solve this two problems simultaneously.Conventional at present processing method all is earlier the product of the bacterium of having gone out to be carried out the EO residual quantity to discharge, these methods adopt dryer or baking oven that packing is dried again, though can be dried DeGrain to product moisture, be difficult to control, moisture situation not up to standard often occurs.
Summary of the invention
The problem that the present invention need solve provides the method for a kind of combined packaging bag and sterilizing-drying thereof.It adopts epoxyethane to the sterilization of the medical supplies in the combined packaging bag, then carries out drying, gets rid of the moisture in the packaging bag.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of combined packaging bag that is used for the medical supplies sterilizing-drying, it is combined by the packing inside bag that is inserted in the outer packaging bag.
A kind of method that adopts described combined packaging bag to the medical supplies sterilizing-drying comprises the following steps:
[1] medical supplies subject to sterilization are put into packing inside bag, standby;
[2] packing inside bag that medical supplies subject to sterilization will be housed is put into outer packaging bag, and outer packaging bag is sealed;
[3] outer packaging bag being put into the sterilization stove sterilizes with epoxyethane;
[4] after sterilization is finished, the temperature of sterilization in the stove risen to 30 ℃-90 ℃, is evacuated to force value and is the negative 100KPA of negative 20KPA--, in the sterilization stove, charge into concentration and be 99.999% nitrogen, kept 10-60 minute, emit gas and recover normal pressure;
[5] repeating step [4] is 5-20 time, and residual epoxyethane and moisture are fully cemented out;
[6] take out sterilized outer packaging bag, make up at packing inside bag and outer packaging bag lap and seal, promptly get by double-deck combination packaging bag hermetic package and through the medical supplies of sterilizing-drying.
Beneficial effect of the present invention is: the present invention can get rid of the moisture in the leak free combined packaging bag and the residual quantity of epoxyethane, (the described displacement number of times of step [4] is many more to reach desired standard, residual quantity is few more), thereby prevent product in effective age, owing to the too high problem that causes that product function lost efficacy of the moisture in the packaging bag.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a combined packaging bag scheme drawing of putting into the sterilization stove.
Fig. 2 is a flow scheme of the present invention.
The specific embodiment
Embodiment 1
As shown in Figure 1: a kind of combined packaging bag that is used for the medical supplies sterilizing-drying, it is combined by the packing inside bag 1 that is inserted in the outer packaging bag 2.
As shown in Figure 2: a kind of method that adopts embodiment 1 described combined packaging bag to the medical supplies sterilizing-drying comprises the following steps:
[1] medical supplies subject to sterilization 3 are put into the good aluminium foil packing inside bag 1 of obstruct power, standby;
[2] packing inside bag 1 that medical supplies subject to sterilization 3 will be housed is put into the good dialysis bag pack 2 of exosmosis power, and outer packaging bag 2 is sealed;
[3] outer packaging bag 2 being put into the sterilization stove sterilizes with epoxyethane;
[4] after sterilization is finished, the temperature of sterilization in the stove risen to 70 ℃, is evacuated to force value and is negative 60KPA, in the sterilization stove, charge into concentration and be 99.999% nitrogen, kept 40 minutes, emit gas and recover normal pressure;
[5] repeating step is [4] 8 times, and residual epoxyethane and moisture are fully cemented out;
[6] take out sterilized outer packaging bag 2, make up at packing inside bag 1 and outer packaging bag 2 laps and seal, promptly get by double-deck combination packaging bag hermetic package and through the medical supplies of sterilizing-drying.
