DETAILED DESCRIPTION OF THE INVENTION The present invention is for blocking microorganisms for preventing or at least minimizing the transmission and transmission of pathogens to dental, medical and surgical handpieces, hoses and sheathed wires used during dental, medical and surgical procedures. It relates to a drape device.

There are various types of dental, medical and surgical instruments used in connection with relatively long appendages such as air or water injection hoses, electric cords or fiber optic cords. Specific examples are high and low speed perforations, water and air syringes. , Suction handles, Electrosurgical handpieces, Bovies, Ultrasonic counters, Fiber optic cables and rods, Surgical fiber retractors, Cryosurgery handpieces, Black sheet cutters and osteotomy, Joints, bronchial and gastroscopic endoscopes, laparoscopic surgery, and surgical laser instruments.

Conventionally, hoses and wires used in internal medicine and surgery are sterilized and sterilized with ethylene oxide gas before use. However, this method not only shortens the life of expensive instruments, but also the operating room and central supply system. In order to maintain it, a lot of time and manpower was wasted.

In addition, sterilization and sterilization of cryosurgical handpieces, laser devices, and optical fiber devices has been a great challenge. Moreover, since most small hospitals do not have ethylene oxide gas sterilizers, the devices used for simple surgery in these small hospitals are almost contaminated. In addition, dental instruments used in dentistry are susceptible to contamination because their surfaces are difficult to disinfect, and as a result, it is very difficult to maintain sterile conditions. The issue of communicable outbreaks to minimize the likelihood has arisen seriously for dentists and the public.

For packaged sanitary drape that can be easily installed on handpieces and their extended accessories without contaminating the outer surfaces of various types of difficult-to-disinfect handpieces, hoses and sheathed wires as described above. While necessity has been desired, the problem is dealing with drape without contaminating the drape with bacteria falling from the operator's hand or appendage, while installing an elongated drape of 3-6 feet in length in the handpiece attachment. Was very cumbersome.

The inventor has disclosed a drape device which solves the above problems in Patent Application No. 86-11508, but the support tube and the sealing ring for accommodating the hand pieces to meet various kinds and standards of medical hand pieces are also included in the standard. It was not practical because it had to be matched, and there was a fear that pathogenic microorganisms would penetrate through the perforation line outside the package, and there was a problem that it was difficult to manufacture due to the complicated structure of the anterior part of the buoy connected to the lip cord.

Therefore, the present inventors have made various efforts to solve the above-mentioned problems, and as a result, they have invented a drape device which is very simple in its structure, which is free of a support tube and a sealing means for accommodating medical handpieces. .

An object of the present invention is to sterilize in a fast, efficient and compulsory way to prevent contamination of pathogenic microorganisms and consequent transmission to medical handpieces that are difficult to disinfect and hoses and sheathed wires extending from them. It is to provide a drape device for blocking microorganisms that can be maintained.

Hereinafter, with reference to the accompanying drawings will be described in detail. 1 is a perspective view of a drape device 1 showing one embodiment of the present invention, and FIGS. 2 and 4 are each an embodiment of the present invention. 2 is a cross-sectional view of one embodiment of the drape device 1 of the present invention, wherein the drape device 1 is a circular slip ring (outer ring) 2 and an inner ring (made of polyethylene). 2a '), and a tubular 1-2 m long sleeve formed of a thin, soluble, impermeable material, a linear low density polyethylene film, which is compactly folded inside the inner ring 2a' and has an opening at both ends (3) It is composed of

Here, one end of the sleeve 3 is circumferentially positioned at a position coinciding with the convex portion 2 'formed on the inner surface of the outer ring 2 and the outer surface of the inner ring 2a. It is clamped together between the outer ring 2 and the inner ring 2a 'engaged with the formed recess 2a', which is shown in detail in FIG. The other end of the sleeve 3 has a V-shaped end and is pointed at the end, and this end is attached to the ethylene oxide gas sterilizing tape 4a whose tabs on the outside of the outer ring 2 are blue. Two outer tapes are attached to the outer surface of the outer ring (2), one of which is a tape (4a) of blue color of the tab to which one end of the sleeve is attached; The tape 4b is colored red to attach to the connection portion of the tape.

4 is a cross-sectional view of another embodiment of the present invention, the drape device 1 is a circular slip type (2) and the sleeve is compactly folded therein and one end thereof is adhered to the outer surface of the slip ring (2) 3) and is essentially the same as the embodiment shown in FIG. 2 except that the inner ring 2a is not used. In the method of using the drape device 1 of the present invention, first, the drape device 1 packed in a sterile packaging bag is taken out, and then, as shown in FIG. 5, the slip ring 2 of the drape device 1 is held and the blue tab is attached. Simply removing the tape 4a shows the front hole of the sleeve 3 as shown in FIG. 6, and pushes the device to the desired portion through the center hole of the slip ring 2 as shown in FIG.

Push the instrument to the desired part and attach the end of the sleeve 3 to the instrument with blue tape 4a as shown in FIG. 8 and cover the instrument with the sleeve 3 as shown in FIG. Tighten the tape (4b) with the red tab and hold the instrument with one hand as shown in Figure 10, and hold the slip ring (2) of the drape device (1) with the other hand to cover the entire hose or cable. Pull out long.

Insert the extracted ring into the ring clip (5) as shown in Figure 11 and use the mechanism. When the present invention removes the drape device 1 after using the instrument, remove the tapes 4a and 4b attached as shown in FIG. 12, hold the tape 4a as shown in FIG. 13, and pull the end of the instrument into the sleeve. After holding the instrument with one hand, the sleeve 3 is peeled upside down as shown in FIG. Since the sleeve is peeled upside down, the material on the surface of the drape device 1 can be removed without contacting hands or other parts.

As described above, the drape device of the present invention is extremely simple in structure and easy to use, and can be used for handpieces for medical, surgical and dental purposes, and for long lengths of hoses and coated wires used in connection thereto. In addition to being extremely easy to cover inside, the device and its accessories are covered by pulling down the drape device of the present invention without contaminating a sterilized hand of a specialist, thus sterilizing in a quick, efficient and economical manner. It is an invention that can maintain a state.

Therefore, by using the drape device of the present invention, it is possible to more reliably protect the health of the patients.
