Embodiment 1

[0054] Embodiment 1: a kind of pretreatment device before sterilization (see attached Figure 6 ), including a box body 9, a heating system connected to the box body 9, a humidification system, a hot air supply system, a vacuum system and a PLC.

[0055] Wherein box body 9 comprises the cylinder body 1 that is the rectangular parallelepiped of open both ends that places horizontally (referring to attached figure 1 ), the side wall of the cylinder body 1 is a double-layer structure, the inner layer is a cuboid with openings at both ends, and the outer wall of the inner layer is provided with a plurality of ring-shaped open-loop water jackets 3 arranged along the length direction of the box body 9, and the water jacket 3 A water inlet 4 and a water outlet 5 are provided at the open ring, and the water inlet 4 of one water jacket 3 in the adjacent water jacket 3 is connected with the water outlet 5 of the other water jacket 3, and the whole water The jacket 3 forms a channel; th...

Embodiment 2

[0062] Embodiment 2: a kind of pretreatment device of product before sterilization (see attached Figure 7 ), its structure is basically the same as that of Embodiment 1, the difference lies in the design of the cooperation between the airtight door 6 and the cylinder body 1:

[0063] The upper end face of cylinder body 1 is fixed with the two-way air cylinder 10 that is connected with sealing door 6 upper end (see attached image 3 , 4 ), the upper end of the airtight door 6 fixes a rectangular connecting block 28, and the middle part of the connecting block 28 extends a connecting rod 29 toward the direction of the two-way cylinder 10, and the two ends of the connecting rod 29 are respectively connected to the connecting block 28 and the piston The movement of the sealing door 6 is driven by the piston movement of the two-way cylinder 10. The air holes at both ends of the two-way cylinder 10 are connected to the air compressor 24 through the pipeline 12, the electric contro...

Embodiment 3

[0066] Embodiment 3: a kind of pretreatment device of product before sterilization (see attached Figure 6 ), its structure is basically the same as that of Embodiment 1, and its difference lies in the design of the sealed door 6:

[0067] The airtight door 6 is a double-layer structure, and the inner layer is a flat plate. Eight sealing spaces 13 are arranged on the outer end surface of the flat plate. figure 2 ), the sealed space 13 is provided with a water inlet hole 4 and a water outlet hole 5, and the sealed space 13 is connected in sequence through the pipeline 12, and the water inlet hole 4 of the first sealed space 13 is connected with the hot water circulation pump of the heating system through the pipeline 12 The outlet hole 5 of 19 is connected, and the outlet hole 5 of the last sealed space 13 is connected with the hot water container 18 of heating system through pipeline 12; The outer layer is the shell that matches with inner layer plate. For strengthening the ...

Abstract

The invention belongs to the technical field of sterilization and relates to a pretreatment device and process of products before sterilization. By utilizing the invention, the problems that after being sterilized by the previous ethylene oxide sterilizers, the absorbable sutures have relatively high ethylene oxide residues and relatively high humidity are solved, thus the requirements for asepsis, low ethylene oxide residues and low humidity of the sterilized sutures are met. The sterilization process is characterized by comprising the following steps: firstly, maintaining the temperature ina container; secondly, introducing hot air and wet gas into the container; finally vacuumizing the container and repeating the above steps. The equipment for sterilization comprises a box body, a heating system, a humidifying system, a hot air supplying system, a vacuum system and a programmable logic controller (PLC), and the heating system, the humidifying system, the hot air supply system, thevacuum system and the PLC are connected with the box body.

Description

technical field [0001] The invention belongs to the technical field of sterilization, and relates to a pretreatment device and process for products before sterilization. Background technique [0002] When using a sterilizer for sterilization, the method of bacterial growth and then sterilization is generally used; because most of the bacteria attached to the surface of the object are in the spore state, and the bacteria in the spore state have strong resistance and are not easy to kill; therefore It is necessary to keep the object to be sterilized in a certain temperature and humidity environment, so that the bacteria can fully grow. When using a sterilizer for sterilization, in order to meet the temperature requirements, the object is generally heated by thermal radiation, that is, a heater is installed in the sterilizer, and the object is sterilized from the outside to the inside through the heat radiation of the heater. Heating; as for humidity requirements, steam is int...
