Embodiment 1

[0063] Embodiment 1: A kind of sterilized use equipment of absorbable suture (see attached Figure 6 , 7 , 8), including the control cabinet equipped with PLC (not shown in the figure), the box 9 and the heating system connected to the box 9, vacuum system, dosing system, humidification system, compressed air system, vaporization system, drying Gas injection system, a waste gas recovery box 30 connected to the outside of the vacuum system;

[0064] 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 including inner and outer shells, 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 tanks arranged along the length direction of the box body 9 Jacket 3, the water jacket 3 is provided with a water inl...

Embodiment 2

[0071] Embodiment 2: A kind of sterilized use equipment of absorbable suture (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:

[0072] 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 control valv...

Embodiment 3

[0075] Embodiment 3: A kind of sterilized use equipment of absorbable suture (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:

[0076] 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 intens...

Abstract

The invention provides a sterilization process and equipment of absorbable sutures. The invention belongs to the technical field of sterilization and relates to an ethylene oxide sterilizer and process of absorbable sutures. According the invention, the problems that after being sterilized by the previous ethylene oxide sterilizers, the absorbable sutures have relatively high ethylene oxide residues and relative 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 characterizedby comprising the following steps: firstly maintaining the temperature and humidity in a container; secondly introducing ethylene oxide into the container; and finally, vacuumizing the container. Theequipment for sterilization comprises a control cabinet with a programmable logic controller (PLC), a box body, a heating system, a vacuum system, a feeding system and a humidifying system, and the heating system, the vacuum system, the feeding system and the humidifying system are connected with the box body.

Description

technical field [0001] The invention belongs to the technical field of sterilization, and relates to an ethylene oxide sterilizer for absorbable sutures and a technique. Background technique [0002] Absorbable suture is a small medical product that is absorbed by the human body through hydrolysis. Its packaging needs to have extremely high antibacterial and sealing properties to prevent microbial contamination from the external environment and hydrolysis reactions from water and steam. , to keep it sterile and dry after sterilization. [0003] Usually, the sterilizing method of absorbable suture adopts chemical method, and the sterilizing agent selected in the sterilizing process is generally ethylene oxide. Ethylene oxide is a poisonous, flammable, and explosive gas. The sterilization mechanism is to germinate bacterial spores on the surface of the object to be sterilized and reproduce bacteria under a certain temperature, pressure, and humidity. Ethylene oxide is absorb...
