Abstract

PURPOSE:To achieve handiness of handling and inspection with ease of cleaning, disinfecting work and the like by providing a heat shrinkable tube and a yarn- like body which is buried into a skin of the tube to cleave it when the probe is covered closely therewith. CONSTITUTION:This cover has a heat shrinkable tube 21 which covers an endoscope probe closely being shrunk by heating. A yarn-like body 22 is arranged which is buried into a skin of the tube 21 along the length thereof to cleave the tube 21 by pulling when the probe is covered closely with the tube 21. A scope 1 of the endoscope in this example comprises a probe 11 to be inserted into a body cavity or the like, a manipulating section 10 on hand, a universal cord 12 and the like. Then, the probe 11 is covered with the endoscope probe cover 2. The covering of the probe 11 with the endoscope probe cover 2 is made before operation such as inspection with the endoscope and after the operation, the probe cover 2 is cleaved and removed by pulling the yarn-like body 22, thereby facilitating work of cleaning and disinfecting the endoscope probe.

Description

Detailed Description of the Invention [Objective of the Invention] (Industrial Application Field) The present invention provides an endoscope for inserting a probe into a body cavity to observe the inside, etc. , relates to an endoscope probe cover that facilitates disinfection, cleaning, etc. before and after insertion.

(Prior Art) An endoscope is inserted into an open cavity in the human body, such as the stomach or intestine, and is used to examine and diagnose lesions within the body cavity from outside the body.

Therefore, an endoscopic probe inserted into a body cavity must be thoroughly cleaned and disinfected, and after use, it must be disinfected by washing away body fluids and the like that have adhered to it.

Disinfection of endoscopes, etc. is generally carried out by immersion in chemicals, chemical disinfection using methylene peroxide, etc. 6 (Problems to be Solved by the Invention) However, such disinfection This work may deteriorate the surface of the endoscopic probe and shorten its lifespan. For this reason, in the past, disinfection work had to be carried out in as short a time as possible and with the lowest possible drug concentration, which made handling of the endoscope, and thus endoscopy itself, difficult and time-consuming.

The present invention has been made in view of the conventional circumstances, and provides an endoscope that facilitates cleaning and disinfection of the endoscope 70-b and simplifies handling and inspection of the endoscope. The purpose is to provide a probe cover for

[Structure of the Invention] (Means for Solving the Problem) In order to achieve such an object, the endoscope probe cover according to the present invention has the following features: and a filamentous body that is embedded in the epidermis of the tube in the longitudinal direction and cleaves the tube when pulled up when the tube is closely covered with the probe.

(Function) If the endoscope probe cover has such a configuration,
Before using the endoscope, the heat-shrinkable tube is contracted by heat treatment, such as hot air, hot water, or infrared irradiation, and tightly coated on the endoscope probe. Also, after use,
By pulling up the filament, the heat-shrinkable duplex closely covering the 70-b can be cleaved and easily removed.

In this way, it becomes possible to protect the endoscope probe and to simplify and facilitate cleaning and disinfection before and after use.

(Embodiment) FIG. 1 is an explanatory diagram of an endoscope probe cover according to an embodiment to which the present invention is applied.

A heat-shrinkable tube 21 that shrinks when heated and tightly covers the endoscope probe, and a heat-shrinkable tube 21 that is embedded in the epidermis of the tube 21 in the longitudinal direction and is pulled up when the tube 21 is tightly covered with the probe. The probe cover 2 is constituted by the filamentous body 22 to be cleaved.

The heat-shrinkable tube 21 is made of, for example, vinyl acetate chloride (EV
A), polyurethane, polyethylene, silicone rubber, fluororubber, or other material is used to form a material with a thickness of, for example, 0.
It is formed as thin as about 0.002 mm to 0.1 mm, and is stretched in the radial direction to improve its shrinkability. Further, the tip portion 23 is a portion that covers the observation portion at the tip of the endoscope probe, and is made of a transparent and flexible material, such as silicone rubber.

Note that this tip portion 23 is unnecessary in cases such as endoscopy that uses air and water supply, suction, forceps, etc., and in such cases, it must be removed and used, or it may be removed. A probe cover with the tip portion 23 open may be prepared separately.

Further, as the filamentous body 22, a thin and durable material such as Geppler or silk thread is suitable, and it is buried with one end exposed outside the tube 21 so that it can be easily pulled up when the tube 21 is torn.

At this time, in order to further facilitate the cleavage, the tube 21
For example, perforations or the like may be provided at the buried location of the filament 22 to such an extent that no holes will be formed.

Further, in the example shown in FIG. 1, the filamentous body 22 is buried substantially straight along the longitudinal direction of the tube 21, but it is also possible to bury it in, for example, a spiral shape. Further, the filamentous body 22 may be attached to or buried in the inner wall or the skin of the tube 21, and the number of filamentous bodies 22 is not limited to just one, but by embedding a plurality of filaments, etc., cleavage can be made easier. Can be done.

Moreover, FIG. 2 is an explanatory view of the main parts of an endoscope covered with an endoscope broof cover according to the present invention.

A scope 1 of an endoscope includes a probe (also called a guiding tube) 11 inserted into a body cavity, an operating section 10 at hand, and a connector 1 connected to an endoscope irradiation light source, an air/water pump tank, etc. (not shown).
It is composed of a universal cord 12 and the like connected via 3.

The probe 11 is covered with the endoscope probe cover 2 according to the present invention.

Covering of the probe 11 with the endoscope probe cover 2 is as follows:
This is done before a surgery such as an endoscopy, and after the surgery, the filament 22 is pulled up and the probe cover 2 is split and removed, thereby making cleaning and disinfection of the endoscopic probe easier. Here, by disinfecting the probe cover 2 in advance and sealing it, the disinfecting work can be further facilitated.

Further, in order to shrink the probe cover 2 so that it comes into close contact with and covers the probe 11, various heat treatment methods such as applying hot air, soaking in hot water, or irradiating with infrared rays can be used.

[Effects of the Invention] As explained in detail above, the endoscope probe cover according to the present invention is used to attach and tightly cover the endoscope probe before surgery such as endoscopy, and after surgery. By removing it, cleaning and disinfection of the endoscope probe becomes simple and easy. At this time, body fluids etc. adhering during endoscopy etc. can be discarded together with the probe cover, and the endoscopic probe is protected, so the probe suffers less pain and its lifespan is extended.

In addition, the probe cover can be easily removed by pulling up the buried filament, which saves time and effort.
