Description

The invention belongs to the group of small, reusable biomedical devices and can be used for the inactivation, washing, drying, sterilization, storage and presentation of small tubular instruments for microbiological, veterinary surgical, gynecological research or medical practice.

A known device (Kashanchi Behnam, Hypodermic needle storage apparatus, Patent US 5,527,296, 1996) is used for sterilization of medical needles, storage and delivery of steriles. The device is narrowly specialized for needles only and is not designed for decontamination, washing and drying of instruments.

A known device (JI.P.reHHTe, Yctpohctbo jum μοηκη ποπμχ MemmHHCKHX H3ąenHH c y3K0if ropnoBHHOH, Abt. Cb. CCCP 1634558 A 1, 1991) is designed for washing and drying of plague pipettes. In part, it can be used for sterilization and sterile storage with some modifications. This appliance is not designed for decontamination of instruments, but is washed by plugging in a tap, thus consuming a lot of water. The device does not solve the problem of placing instruments at work either.

The goal is to achieve better working efficiency and expanding operational capabilities

This is achieved by the creation of a universal case for sterile tubular instruments (hereinafter referred to as the case), which can accommodate various small tubular instruments for their decontamination, washing, drying, sterilization, sterile storage, and with the help of the sterile instrument.

The case has a stand, which consists of two round shelves with holes on the axis for positioning the instruments. One shelf has a sealing ring with sealing lids that are connected to, corresponding to the scale marks on the instrument placement shelf. There are three scales, located above the shelves, on the coupling on the axle. The stand is pushed into a cylindrical receptacle, a cylinder which is hermetically sealed with a lid fitted with a holder for picking up instruments from the case. All parts of the case must be made of heat-resistant sterilizing materials and decontaminators.

The case for sterile tubular instruments consists of the following parts (see Fig. A - case in working condition; B - stand; C - cylinder with cap) where:

1. - axis of the stand,

2. - shelf sealing ring,

3. - rack sealing shelf,

4. - stand shelf,

5. - scales of instrument placement marks on shelves,

6. - scale of instrument placement marks in the stand,

7. - tubular instruments in stand,

8. -cylinder,

9. - cylinder cover,

10. - holder,

11. - sealing cap,

The case works in the following way:

Instruments 7 are placed in the stand according to the marks on the scale 5, - pass through the slits 4 of the rack and the corresponding sealing slit 3 of the rack 3. The slots of the unused rack 3 are closed by sealing lids 11 and their position is reflected in the marking scale 6. The stand, with the instruments 7 therein, is inserted into the cylinder 8 as a piston. 9 and hermetically sealed cylinder 8. Hermetically screwed into holder 9, hermetically screwed into cap 9, thereby forming a hermetic environment divided into two parts of a shelf 3 on which a sealing ring 2 is located. different pressures are created on both parts, forcing the liquid to seep inside the instruments 7 to one side and the other and thus to actively wash them. When the decontamination is completed, the holder 10 is unscrewed and the decontaminant is emptied by attaching the case to the decontamination tank. The case is connected to a tap or filled with water, and by turning the holder 10, the stand 8 in the barrel is pulled back, and the instruments are actively rinsed with water. After unscrewing the holder 10, the water is discharged from the case and filled with distilled water, and the holder 10 is screwed in again and the stand in the cylinder 8 is pulled - the instruments 7 are actively rinsed with distilled water. When the washing is complete, the stand is emptied of water by unscrewing the holder 10 and placing the case in the oven on axis 1 to dry the instruments. The case is placed for sterilization of the instruments 7 in a sterilization cabinet (autoclaving can also be done, which then requires no drying operation and the holder 10 can be released to allow water vapor to enter the inside of the case). After sterilization, the case holder 10 must be screwed in to create an airtight environment for the instruments 7. This position holds the instruments in the case. For the operation of the instruments 7, the axis 1 of the stand is pulled from the barrel so that the desired instrument is in the holder 10. The holder 10 is pivoted, clamping and locking the instrument. By unscrewing the holder 10, the instrument 7 is pulled out of the case and the instrument 7 is released by pressing the end of the holder 10 and placed into operation.

The extension of the expansion capability is achieved by the fact that the case replaces a whole range of other devices (decontamination dishwasher sterilization packages, instrument for operation) and it can prepare several types of tubular instruments for sterile operation. Better work efficiency is achieved by the fact that decontamination and washing are carried out by applying pressure in the cylinder, hermetically split into two parts. Instruments do not need to be rerouted before each operation (washing, rinsing, drying, sterilization, instrument operation) - saving time ', water, reducing the risk of injuries to instruments while sterile operation, longer life.

For example: several micropiped medical needle capillaries need to be prepared for sterile operation. We place these devices on the stand, at their markings on the scales 5, since the scales 5 and 6 are connected, so the marks on the scale 6 show where the instrument is located on the stand. The stand is inserted into cylinder 8, filled with decontaminating fluid, and a cap 9 is placed on the axis 1 and a cylinder 8 is covered therewith. The axis 1 is pulled over the cylinder and left to neutralize for some time by pulling several times. cylinder 8 axis. The next step is to release the aggressive material from the case by unscrewing the holder 10 and, after connecting the case to the decontaminant reservoir, expels the liquid from the case by pulling the stand 8 on the cylinder 8 behind the axle 1. Fill the case with water and screw the holder 10 and pull the axle 1 in cylinder 8. The water must be changed until the decontamination of the instruments and the inside of the case has been effected. The final rinse is done with distilled water. As the distillation water is expelled from the case, the case is placed on axis 1 in the oven. Once the instruments are dried, the case is placed in a sterilization cabinet for sterilization of the instruments. After sterilization, check that the holder 10 is fully screwed in and the instruments are held in the case until required for sterile operation. Instruments are brought into operation by rotating the cylinder cover 9 so that the holder 10 is at the mark of the required instrument on scale 6, the axis 1 is pulled from the cylinder 8 until the instrument reaches the holder 10 and then the holder 10 is unscrewed from the case taken in hand, needle pressed onto syringe, capillary inserted into device, etc.).
