JP2012200725A - Instrument washing dryer with turn table for fixing instrument in inclined circular washing tank - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide an automatic washing dryer reducing risk of secondary infection in medical facilities.SOLUTION: A washing liquid 6 warmed up to about 40°C is injected in the circular washing tank 1 inclined by about 20° from a spray nozzle 5 to the middle of the circular washing tank 1. A plurality of physical washing effects such as an impact in rushing onto a washing liquid surface, wave making resistance that occurs in moving on the washing liquid surface or in the liquid, a flow liquid effect in coming out from the washing liquid, and rotationally moving, and a beating washing effect by a washing liquid shower sprayed from the washing liquid spray nozzle 5, occur to the instrument 10 rotationally moving in the circular washing tank 1. After completion of a rinse operation, a fixed quantity of alcohol is sprayed to the instrument 10 from an alcohol spray nozzle to change an adhered droplet into water-added alcohol. Warm air warmed after being sterilized by an HEPA filter after completion of spray of the alcohol is strongly blown into the circular washing tank 1 from an air supply port, and the water-added alcohol adhered to the rotating instrument is vaporized and dried evenly in a short time.

Description

Detailed Description of the Invention

  The present invention is an automatic washing and drying machine that highly removes contaminating organic substances attached to medical instruments such as surgical instruments, treatment instruments, and endoscopes used in medical facilities, and dries in a short time.

  Blood and protein are attached to equipment used in medical facilities. Immediately after use, there is no time for washing, and the organic matter that has dried and stuck is automatically washed by ultrasonic or disinfector. It is not possible to remove it by itself, and it takes time and labor, such as performing a manual exfoliation work in advance, and there is a risk of infection to workers. It is said that there is.

  Even if the device contains a little organic matter, all microorganisms will be killed by high-pressure sterilization, but in rare cases, the organic matter remaining in the device while the sterilized device is taken out of the sterilization container and prepared for use. In addition, microorganisms (bacteria) accidentally attached from the outside may grow by using organic matter as food, and may infect patients who use the device.

In facilities that treat urgent patients, such as emergency medical centers and emergency outpatients, it is impossible to know in advance whether a patient is positive for infectious microorganisms.
Although these patients may be positive for highly infectious microorganisms such as HIV and HCV, there are currently no special facilities for cleaning and disinfecting medical devices used for them.

  The present invention eliminates manpower that may cause variations in cleaning results or infect workers, and does not require cleaning procedures at the site of use of medical instruments, and can be sufficiently cleaned and dried in a short time. It is an automatic washing dryer.

In the present invention, the instrument 10 is fixed to the turntable 2 mounted inside the circular cleaning tank 1 inclined at 20 degrees or more, and the turntable 2 driven by the motor 3 is rotated while the cleaning liquid jet nozzle 5 rotates the circular shape. The cleaning liquid 6 heated to about 40 ° C. is put to the middle of the cleaning tank 1.
The instrument 10 that moves in the circular cleaning tank 1 by the rotation of the turntable 2 impacts when entering the cleaning liquid surface, wave-making resistance generated by moving the liquid surface and in the liquid, and rotates and moves out of the liquid surface. A plurality of physical cleaning effects are exhibited, such as a flowing liquid effect at the time, and a tapping cleaning effect in which the angle is changed by a cleaning liquid shower from the cleaning liquid injection nozzle 5.

  Cleaning using these multiple physical effects is not suitable for ultrasonic devices such as endoscopes equipped with CCDs or precision lenses that are sensitive to vibration and shock, or soft rubber products. This is a method for overcoming washing unevenness caused by showers.

In the present invention, after the detergent cleaning with the cleaning liquid 6 is performed for a predetermined time, the liquid is drained, and then the cleaning liquid 6 attached to the instrument 10 is removed, and the overflow rinsing with warm water is performed twice or more by exchanging the warm water.
After the prescribed rinsing is completed and the warm water is discharged, a predetermined amount of alcohol is sprayed from the alcohol injection nozzle 7 onto the appliance 10 fixed to the rotating turntable 2 and mixed with the water droplets attached to the alcohol 10 And
Next, the outside air sterilized by the hepa filter is heated to 40 to 50 ° C. with a heater and is strongly fed from the air feeding port 8, and the hydroalcohol attached to the instrument 10 is forcibly dried in a short time without unevenness.
Thereby, microorganism recontamination which is easy to occur at the time of water droplet wiping or drying can be prevented.

  It is sectional drawing of a circular washing tank and a turntable.   It is a top view of a circular washing tank and a turntable.
