Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application] The present invention relates to an absorbent material for accommodating elongated medical instruments, especially dental instruments, such as straight or curved handpieces, when delivering maintenance fluids. The present invention relates to a medical instrument storage device having a storage envelope.

[Problems with the prior art] In the case of the above-mentioned medical device, the sleeve of the device, for example, the internal parts of the handpiece sleeve, such as the internal partition wall, the drive shaft that drives the tool, the bearing of the rotor shaft, or the shaft itself cannot be coated with maintenance fluid. must be processed from time to time. The maintenance fluid is, for example, a liquid cleaning or care agent, such as oil.

For the above-mentioned treatment, it is known to introduce maintenance fluid under pressure into the instrument, for example through a supply line coming from a spray can, through an opening at the end of the instrument, usually at the drive connection end. For this purpose, the supply tube has a nozzle-like mounting mouthpiece at its end. This mouthpiece is attached to the instrument opening. Instruments of the type described above have one or more separate openings, for example tool through-holes, for structural or operational reasons. Excess or dirty maintenance fluid that has introduced maintenance fluid flows out through this opening, which is not only annoying for the person holding the instrument with their fingers, such as a doctor or assistant, but also a sterile or sanitary problem. This is unacceptable for a number of reasons.

In order to avoid the above, it is known to use containment envelopes made of absorbent material to contain instruments during delivery of maintenance fluids. This containment envelope may consist of a cellulose or other layer, or a suitable cloth or cloth cut, which is in the possession of the doctor or dentist. However, there is a problem in that maintenance fluid can already seep into the housing envelope when only a few instruments, often only one instrument, is filled, and the maintenance fluid leaks onto the hands and fingers of the doctor or assistant.

[Object and Structure of the Invention] An object of the present invention is to provide a medical device storage device that can prevent the hands or fingers of a person who maintains the medical device from coming into contact with the maintenance fluid used to supply fluid to the device. be.

The purpose is to provide a device for accommodating an elongated medical instrument during the delivery of a maintenance fluid, having a containment envelope of absorbent material, said containment envelope being disposed within a sac of impermeable material. A medical device, characterized in that the sac has an opening to which an elastic sealing means is attached, the opening of the sac being sealed at least before first use by said elastic sealing means. This is accomplished by a containment device.

[Operations and Effects of the Invention] The present invention is constructed as described above, so that even if the medical device to be maintained is held in hand when feeding the maintenance fluid, the maintenance fluid will not penetrate into the housing envelope. Or equipment wet with maintenance fluid does not come into contact with the hands or fingers of the handler. In other words, the maintenance fluid that permeates into the containment envelope is reliably contained by the impermeable material sack.

In addition, in order to supply maintenance fluids such as oil to the equipment,
Even if the containment device is used repeatedly, hands and fingers will not come into contact with the liquid. Even if the maintenance fluid is used in a gaseous state or mixed with a gas, it will not come into contact with the hands or fingers of the operator.

Further, since the opening of the storage device is provided with an elastic sealing means, when the storage device is used, the opening can be closed by the sealing means to prevent invasion of bacteria and the like, and the storage device can be used repeatedly.

[Examples] Examples of the present invention will be described below with reference to the drawings.

A device for housing an elongated instrument, in the illustrated case an angular dental handpiece 1,
It consists of a storage jacket 2 made of an absorbent material and containing the storage jacket 2, and a sack 3 made of an impermeable material in which the storage jacket 2 is placed.

The sac 3 adheres closely to the containment envelope 2 and is made of a transparent flexible material, for example polyethylene. In the embodiment shown in FIG. 2, the sack 3 has a window 4 made of transparent material, the rest of which is made of opaque material.

In order to avoid bacterial contamination of the absorbent material of the containment envelope 2 and the transmission of bacteria to the instruments, the containment envelope 2 can be impregnated with a disinfectant. If oil is used as a maintenance fluid, this measure is only of a precautionary type. This is because bacteria need water to grow, and oil prevents bacterial contamination from occurring.

The opening 5 of the sac is provided with an elastic sealing member 6, for example in the form of a collar. The elastic sealing member 6 can be formed from a rubber tape forming a simple seal and is arranged so that it can be easily opened. Preferably, at least before the first use, the sack opening 5 is closed by an elastic sealing member 6. The seal is then constructed in such a way that it can be easily opened. In this way, the contents of the tank 3 can remain sterile for as long as possible, at least until the first use of the device. When supplying fluid to the handpiece 1 in the housing envelope 2, it is preferable to close the elastic sealing member in order to prevent excess maintenance fluid, for example in the form of oil mist, from flowing out.

At its end adjacent to the bottom 7 of the sack, the containment envelope 2 likewise has a bottom 8 . This provides good retention of the instruments within the device. In order to further improve this good retention, the contour of the inner surface of the receiving envelope 2 or sac 3 is matched to the shape of the medical device 1.

In the embodiment shown in FIG. 2, an insert 10 made of a permeable or porous material, for example paper such as filter paper or blotter paper, is arranged inside the receiving envelope 2. In the embodiment shown in FIG. The insert 10 fits closely into the receiving envelope 2. The insert 10 extends the service life of the containment envelope 2. In the embodiment of FIG. 1, the insert 10 has at least one tongue 11 that can be grasped or protrudes through the sac opening. In particular, if the insert 10 is shaped like a bag as shown in FIGS. 2 and 3, the tongue 11 pulls the insert 10 out of the bag 3 together with the instrument 1 each time a maintenance operation is completed. You can do this without getting your fingers dirty. The insert 10 has the advantage of acting as a filter, collecting dirt coming from the instrument 1 and preventing subsequent instruments from coming into contact with the contaminated zone of the containment envelope 2.
As shown in FIGS. 2 and 3, the insert 10 is matched to the shape of the medical device 1. As shown in FIGS.

In the embodiment of FIG. 3, a plurality, for example 50 inserts, are provided inscribed one after the other. This makes maintenance of multiple instruments in sequence much easier and faster.

Between the receiving envelope 2 and the sac 3, there is a discoloration caused by the supply of maintenance fluid, so that it is easy to recognize that the receiving envelope 2 is saturated with maintenance fluid, e.g. oil, and must therefore be replaced. layer 12 of material that
is located. Preferably, this layer 12 consists of test paper.

FIG. 4 shows the handling of the device when feeding maintenance fluid. Holding with one hand the sack 3 containing the containment envelope 2 together with the instrument 1 therein, and with the other hand the mounting mouthpiece 13 of one of the delivery conduits 14 of the spray can 15 containing the maintenance fluid under pressure. The device 1 is held in contact with the opening 16 (FIG. 1) at the drive connection end of the device 1, and the release valve 17 of the spray can 15 is operated with the index finger of this hand.
