Equipment for sterilization of bacteriological loops

The invention relates to a device for sterilizing bacteriological loops in an enclosed space of an electrically heated sterilization body which is housed in the body (2) of the device. The sterilization process is provided by a semiautomatic mobile holder (5) of bacteriological loops (7) whose movement between the stroke limiting bar (6) and the stop bar (10) is secured by a tension spring (14). Sterilization loop (7) is achieved immediately after insertion into a sterilization body (the contact of the extended hot-lining. After pressing the hand-grip portion (9) on the holder (5) is bekj teriologická handle (7), which handles ^one prize on the holder (5) with two clips (12), * inserted into the sterilization body in the body (2) of the device 3-cutting spring (14), the upper end of which is fixed in the cube (6) to its original position.

The device according to the invention is intended for microbiological and clinical workplaces where bacterial cultures are used.

The invention solves the sterilization of metal bacteriological loops by using electrical energy in the enclosure of the sterilization body.

Sterilization of metallic bacteriological loops in microbiological practice is carried out almost exclusively by glowing them in the flame of town gas or natural gas. such as sterile boxes, Hansen boxes, and boxes for anaerobic cultivation of bacteria. Electric current sterilization of metallic bacteriological loops is currently being handled in two ways ·

The first method consists in sterilizing the loop in an electrically heated resistance coil. This sterilization method has two major disadvantages: the possibility of electric shock and a large power consumption. Careless handling of the handle may cause the loop to contact the coil. In order to minimize the risk of contact, the resistance coils are designed to be large diameter (minimum diameter 50 mm) for this purpose. However, to heat such a spiral requires a large power input, which values are in the range of 1GOQfc25OQ W.

The second method of sterilization consists in direct heating of the bacteriological loop using a special pulse device. This sterilization requires double bacteriological loops with a loop of a suitable resistance wire. . • This method also has two major disadvantages: high electricity consumption and, since the loop sterilization itself is not carried out in a confined space, environmental contamination may occur during sterilization.

These disadvantages are overcome by the bacteriological loop device according to the invention, which consists of a pedestal which is connected to the body of the device in which the sterilization body is packed with an insulating material, where it is fixed to the lid with an opening in the body. A support column with a mobile bacteriological loop holder, the movement of which between the stroke-limiting block and the stop-block mounted on the vertical carrier, is provided by a tension spring whose upper end is fixed in the stroke-limiting block. The bacteriological loop, which is attached to the loop holder by two clips, is inserted into the sterilization body by pressing the handling bracket. A power cord with a mains plug opens from the front wall of the stand where the switch is located.

The advantages of the bacteriological loop sterilization device according to the invention are manifested in particular in that the sterilization is carried out in the body of the device where the sterilization body is coated with an insulating material which contributes to the low external temperature of the device during sterilization. safety at work with infectious material and avoid contamination of culture media and working environment. Effective sterilization is achieved immediately after inserting the bacteriological loop into the sterilization body using a semi-automatic mobile loop holder. The small size and weight of the device allow easy handling even in very small space *.

The attached drawings show a device for sterilizing bacteriological loops according to the invention. Fig. 1 shows the rest position of the device with the handle, Fig. 2 shows the working position of the device with the handle inserted into the sterilization body, and Fig. 3 shows the plan view of the device after removing the lid of the device body.

In the base 2 of the device, which is connected to the body 2, in which the sterilization body 15 is wrapped, covered with insulating material 16, there is

231 275 power switch located. Bacteriological loop holder 7 is fastened to a metal lid 4 with a hole in the body 2. The mobility of the loop holder 5 is secured by a tension spring 14, the lower end of which is fixed in the loop holder 5 7, whose adjustment can be varied according to the length of the bacteriological loop 7 used. The loop holder 5 is moved by means of a tension spring 14 on the support column 8 after pressing the handle 9. The length of movement of the loop holder 5 on the support column 8 is limited. The attachment of the bacteriological loop 7 on the holder 5 by two clips 12. From the front wall of the pedestal J, an appliance cord with a mains plug 13 exits. After pressing the handle 9, the bacteriological handle 7 is inserted into the sterilization body where it is immediately sterilized. After the sterilization, the tension spring 14 returns the handle 5 with the handle 7 back to the original position defined by the stroke limiting bar 6.

The device for sterilization of bacteriological loops according to the invention is intended for microbiological and clinical workplaces where bacterial cultures are used. In addition to these facilities, the devices can also be used to sterilize small medical instruments, such as needles.
