Sterilizer for medical devices {sterilizer for medical appliance}
[8] The present invention relates to a sterilization apparatus for medical instruments, and more particularly, to a sterilization apparatus for medical instruments that can be sterilized in a short time as well as to minimize the noise generated during sterilization of medical instruments and the like. will be.
[9] In general, various medical instruments and the like should be stored and used aseptically, and various means for sterilizing medical instruments have been proposed. However, some medicines may be used, and methods of sterilization using high temperature steam may be used. have.
[10] Although the use of the drug during the sterilization of the medical device can be used in parts not used in the human body, most of the medical device used for the human body is sterilized using high temperature steam.
[11] Therefore, conventionally, as shown in FIG. 1, a chamber 2 having a heater formed to sterilize a medical instrument or the like, and a reservoir 8 storing distilled water to generate steam on the chamber 2 are provided. ), A vacuum pump (6) formed to lower atmospheric pressure and wet steam in the chamber (2), a cooler (10) installed to lower the low temperature when recovering the wet steam generated on the chamber (2), distilled water and steam It consists of solenoid valves (4), (12), etc. to shut off and supply.
[12] Since the conventional sterilizer formed as described above is transferred to the vacuum pump 6 as it is in the process of releasing water vapor and wet air in the chamber 2 due to the water vapor generated during sterilization in the chamber 2 as it is. , There is a problem that the air containing water vapor is introduced to reduce the efficiency of the vacuum pump (6). Although the temperature is lowered by the cooler 10 installed between the vacuum pump 6 and the chamber 2, the water vapor discharged from the chamber 2 is not removed by the cooler 10 and reduces only the temperature. This lowers the efficiency of the vacuum pump 6.
[13] In addition, noise is generated during vacuum because the vacuum pump 6 for evacuating the chamber 2 is operated.
[14] The noise generated as described above is about 75dB, and the noise increases as the amount of steam flowing into the vacuum pump 6 increases. There is this.
[15] In addition, the medical device sterilized in the chamber 2 is sterilized by the water vapor in the chamber 2, and even after the water vapor remains in the medical device, the moisture remaining in the medical device causes the virus to be infected. Could.
[16] As described above, sterilization takes a long time because the sterilized products are in contact with external air in a state in which the sterilized products are in contact with external air in order to prevent the occurrence of viruses in the sterilized medical container.
[17] Accordingly, the present invention has been made in view of the same problems as before, and its purpose is to increase sterilization power so as not to be infected with a virus or the like when using a medical device before or after using the medical device and at the time of sterilization of the medical device. It is possible to reduce the sterilization time, and to provide a sterilization apparatus for a medical device that can reduce the noise generated in the sterilizer during sterilization of the medical device.

[18] In order to achieve the object of the present invention as described above, a sterilization apparatus for a medical device, a reservoir for storing distilled water for sterilization, a chamber formed to generate steam by heating the sterilized medical device by receiving the distilled water of the reservoir, and A sterilization apparatus for medical instruments, comprising a vacuum pump formed to reduce atmospheric pressure and wet steam in the chamber, and a cooler formed to reduce the high temperature steam temperature generated in the chamber, formed between the vacuum pump and the cooler and in the chamber. Water separator and a negative pressure silencer connected to reduce the noise generated in the vacuum pump is formed to separate the steam generated in the.
[19] The sterilization apparatus for medical devices of the present invention configured as described above will be described in detail below with reference to the accompanying drawings.
[20] 2 is a view showing a sterilization apparatus for medical instruments, Figure 3 is a view showing the configuration of the sterilization apparatus for medical instruments of the present invention.
[21] Sterilization apparatus of the present invention is a heating method, the distilled water stored in the reservoir 30 is supplied to the chamber 36 having a heating function to heat the distilled water in order to sterilize medical instruments and the like.
[22] A solenoid valve 32 is installed between the reservoir 30 storing the distilled water and the chamber 36 storing the sterilized medical device for controlling the amount of distilled water generating steam in the chamber 36. do.
[23] As described above, the distilled water supplied from the reservoir 30 is heated in the chamber 36 to be converted into hot steam to sterilize the medical device.
[24] At this time, after the distilled water of the reservoir 30 is moved into the chamber 36, the vacuum pump 44 is operated so that the vacuum in the chamber 36 is about 580 mmHg so that the pressure in the chamber 36 is lower than the atmospheric pressure.
[25] When the pressure in the chamber 36 is lowered by the vacuum pump 44, the temperature and pressure in the chamber 36 are controlled to 121 ° C, 1kg (f) / cm 2 to 135 ° C, and 2kg (f) / cm 2 to be sterilized. Adjust to a good mood.
[26] The chamber 36 can be automatically adjusted so that the temperature does not rise or fall abruptly by setting a constant temperature by the temperature measuring device 52 installed to control the temperature of the water vapor.
[27] In order to prevent the water vapor generated in the chamber 36 from being discharged directly to the vacuum pump 44, the vacuum pump 44 reduces the temperature of the water vapor by the cooler 40 before sending the water vapor to the water separator ( 42), the water vapor is separated from the air so that the air from which the water vapor has been removed is passed through the vacuum pump 44.
[28] The water separator 42 is introduced into the water separator 42 while passing the water vapor having a lower temperature through the cooler 40 while lowering the pressure and at the same time, dew is generated as the water vapor hits the inner wall.
[29] Since the water vapor can be separated by the water separator 42 as described above, the high temperature water vapor generated in the chamber 36 is not introduced into the vacuum pump 44, so that the vacuum pump 44 is not impaired. I can vacuum the inside smoothly.
[30] The solenoid valve 50 is installed in the lower side discharge path of the water separator 42 to supply distilled water separated from the water separator 42 into the chamber 36.
[31] The vacuum pump 44 installed as described above is used not only to recover the steam generated while vacuuming the chamber 36 to the reservoir 30, but also the noise generated from the vacuum pump 44 passes through the sound pressure silencer 46. This reduces noise.
[32] The sound pressure silencer 46 is to discharge the noise generated by the vacuum pump 44 through the conduit to the sound pressure silencer 46 connected to the sound as the volume is expanded while the sound is attenuated and discharged through the outlet Only finely remaining noise and condensed water vapor are recovered to the reservoir 30.
[33] Therefore, the noise generated from the vacuum pump 44 by the sound pressure silencer 46 and the water vapor to remove the noise generated while being recovered to the reservoir (30).
[34] During the sterilization of the medical device in the chamber 36, the above-described process opens the solenoid valve 48 so as to store the distilled water that has been supplied into the chamber 36 in the water storage tank 30, and then recovers the distilled water. Is activated and the sterilization time is terminated.
[35] After distilled water is extracted from the chamber 36 as described above, the vacuum is applied using the vacuum pump 44 and dried to remove moisture remaining in the medical apparatus in the chamber 36.
[36] Since the solenoid valve 45 and the bacterial filter 53 are installed in the chamber 36 to reduce the drying time during the drying, the solenoid valve 38 is closed in a vacuum state. When the solenoid valve 45 is opened to increase the dryness by giving a change in air pressure, the drying time is shortened because the high atmospheric pressure in the chamber 36 is introduced while the same as the atmospheric pressure in the chamber 36.
[37] In the present invention, the solenoid valve 45 is closed once more while the drying process is performed as described above, and when the solenoid valve 38 is opened and vacuumed to dry the chamber 36, the moisture remaining in the sterilized medical device is completely removed. Evaporates.
[38] As described above, since the medical device sterilized in the chamber 36 is completely dried, the chamber 36 is completely dried to prevent germs from propagating.
[39] Therefore, the sterilization power can be increased so as not to be infected with a virus when used in the human body by the medical apparatus or the like before and after the use of the medical apparatus in detail, and the user can be reduced by minimizing the noise generated during sterilization. There is no effect of rejection and stress.
[40] In addition, the present invention can reduce the time required for sterilization during sterilization process can shorten the sterilization process time.
