JPH0557027A - Contamination prevention cap - Google Patents

Abstract

PURPOSE:To provide a cap for preventing the contamination of a laser treatment device probe capable of maintaining touch sensor function, and easily preventing the contamination and infection due to the contamination. CONSTITUTION:A cap touch sensor 12 comprising an conductive tape of aluminum is formed on the projection 11 of a contamination prevention cap 16 made by vacuum forming of polyvinyl chloride. A conductive section as part of the sensor 12 is bonded to the back of the projection 11 via a hole formed therein. As a result when the cap 16 is mounted to a hood and a probe 7 in the vicinity thereof, the touch sensor of the probe 7 comes in contact with the conductive section bonded to the back of the projection 11, thereby forming electrical continuity. When an operator presses the cap touch sensor 12 to an affected area, using the probe 7 mounted with the cap 16, the touch sensor 12 operates. Laser is thereby generated and transmitted through the annular polyvinyl chloride of the cap 16 inside the cap touch sensor 12, and irradiated to the affected area for treatment.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cap for preventing contamination, and more particularly to a cap for preventing contamination of a medical laser device used for relieving pain and promoting wound healing by using a laser beam.

[0002]

2. Description of the Related Art An example of a conventional laser treatment device will be described with reference to the drawings. In FIG. 4, reference numeral 1 denotes a main body of the semiconductor laser treatment device, a power source key SW2, an irradiation time setting switch 3, an irradiation time display section 4, a probe holder 5, and an internal semiconductor laser drive circuit, control not shown. It is composed of circuits and power supplies. Reference numeral 7 denotes a probe, which is provided with a hood 8 having a laser emission port 9 protruding from the vicinity of its tip portion at its tip portion. Although not shown in the figure, probe 7
Has a semiconductor laser, a touch sensor circuit, and the like inside. Reference numeral 6 is a signal code for controlling the probe 7. In FIG. 5, 10 is a laser emission port 9 of the hood 8.
It is a touch sensor made of a metal ring formed around the. The operator operates the key SW2 of the main body 1 to turn on the power, and after setting the irradiation time by the irradiation time setting SW3,
When the laser emission port 9 of the hood 8 provided on the probe 7 is pressed against the affected area, the touch sensor 10 detects the body surface, and laser light is emitted from the laser emission opening 9 to the affected area to perform treatment.

[0003]

However, when a treatment is carried out in such a conventional apparatus, if there are scratches or contaminants in the affected area and in the vicinity of the affected area, the operator soaks alcohol or the like after the treatment of the patient. It was necessary to perform the disinfection by wiping the vicinity of the laser emission port 9 with a case or the like, but there were problems that it was difficult to know if the disinfection was sufficient and it was troublesome. The present invention solves such a problem, and an object of the present invention is to provide a contamination prevention cap that can easily and reliably prevent contamination of a probe.

[0004]

The contamination prevention cap of the present invention solves such a problem by providing a laser beam emitting port of a probe, a hood, and at least a vicinity thereof, which is sufficiently adhered and covered. A cap that is easy to remove and attach is made of resin that sufficiently transmits laser light, and a metal conductive part of the cap touch sensor that has the same shape as the touch sensor is provided at the portion corresponding to the laser light emission port, and the cap sensor is conductive. By making it possible, the function of the touch sensor is maintained, and the contamination of the probe and the infection due to the contamination are easily prevented.

[0005]

With this structure, the cap for preventing contamination of the present invention is mounted on the hood of the laser treatment device and the probe in the vicinity of the hood so as to be in close contact therewith, and the cap is pressed and treated. By replacing the cap with a new one for each affected area for treatment, it is possible to easily prevent contamination of the probe and prevent infection between the patient and the affected area.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A pollution prevention cap according to an embodiment of the present invention will be described below with reference to the drawings. 1, FIG. 2, FIG. 3, FIG. 4 and FIG. 5, 16 is mounted on a probe 7 having a semiconductor laser (wavelength 830 nm) formed by a protrusion 11 and a base 11b inside by vacuum forming vinyl chloride. An anti-contamination cap (hereinafter abbreviated as “cap”) 12 is a cap touch sensor formed of an aluminum conductive tape, and a part of the metal conductive portion 12
a is adhered to the back side 11a of the cap through the hole 13 formed in the protruding portion 11 of the cap 16, and when the cap 16 is attached to the hood 8 and the probe 7 in the vicinity thereof,
The touch sensor 10 of the hood 8 is on the back side 11a of the cap.
Part of the metal conductive part 12 of the aluminum conductive tape attached to the
A contact is made with a to establish continuity. 14 is a polyester tape sealing tape for closing the hole 13. Reference numeral 15 is a holding projection that projects about 0.5 mm to the back side of the base portion 11b of the cap and produces a gentle holding force with respect to a concave portion (not shown) provided on the surface of the probe 7, and in this embodiment, a cross shape. Were formed in four locations.

The operation will be described below. Cap 1
6 shows a hood 8 shown in FIG. 5 and a probe 7 in the vicinity thereof.
Then, as shown in FIG. A ring of a cap touch sensor 12 formed by an aluminum conductive tape that is electrically connected to the touch sensor 10 of the laser emitting port 9 at the tip of the hood 8 provided on the probe 7 shown in FIG. When a ring-shaped portion is pressed against the affected area, the touch sensor 10 operates in the same manner as when the cap 16 is not attached, laser light (wavelength 830 nm) is emitted, and the cap 16 inside the ring-shaped cap touch sensor 12 is chlorinated. It penetrates the vinyl part and is irradiated to the affected part,
Treatment is administered.

In the present embodiment, the emitted laser light is transmitted through the vinyl chloride portion of the cap 16 inside the cap touch sensor 12, but when the attenuation of the laser light in the transmission portion poses a problem, The minimum necessary holes may be formed in the ring.

According to this embodiment, by replacing the cap with a new one for each affected area to be treated, contamination of the probe can be easily and surely prevented, and infection between the affected areas can be prevented.

[0010]

As is apparent from the above description of the embodiments, according to the contamination prevention cap of the present invention, the probe can be easily and surely contaminated by exchanging the cap with a new one for each treated area. Prevention can be implemented and infection prevention between the patient and the affected area is achieved.

Also in the cap assembling method, a cap made of vinyl chloride, which is vacuum-formed and has holes formed, is used.
Since it is only necessary to attach a modeled aluminum conductive tape or polyester tape, assembly is extremely easy.
