[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a drip liquid receiving member that receives a liquid drip from a suction port used during medical examination, and a suction port to which the drip liquid receiving member is attached.

[0002]

[Prior art]

 The problem of nosocomial infections in medical facilities such as hospitals is that a large number of cases of nosocomial infection due to methicillin-resistant Staphylococcus aureus (MRSA) have been reported along with body fluid-borne viral infections (HIV, HBV, HCV), which is a major social problem. It is of great interest to all patients and the general public.

Due to the nature of its medical practice, dental clinics routinely carry the risk of nosocomial infection due to body fluids of patients and indigenous bacteria in the oral cavity and upper respiratory tract. In particular, aerosols containing saliva, cutting powder, etc., scattered from the patient's oral cavity by tooth cutting with a high-speed air turbine are a major source of pollution in dental clinics. In addition, the aerosols generated by the ultrasonic scaler and the cutting powder generated during the cutting adjustment of the prosthesis on the chair side are also sources of pollution. Even if thorough disinfection and sterilization of fingers and equipment is performed, the risk of nosocomial infection is great if measures against this type of pollution source are not taken. For this reason, intraoral vacuum has been used during tooth cutting with an air turbine, and it has been effective in aspirating aerosol scattered from the patient's oral cavity.

However, this vacuum alone is not sufficient to prevent scattering outside the oral cavity. Therefore, by bringing a suction port called a hood close to the patient's mouth and connecting the suction port to a vacuum suction device with a strong air volume through a suction hose, water, saliva, etc. that splash on the face during treatment can be The cutting powder is sucked in through the suction port to protect dentists and patients and to reduce the amount of dust in the room.

[0005]

[Problems to be solved by the device]

 However, even when the above suction port is used, water and saliva are spattered especially outside the oral cavity when cutting the front teeth with an air turbine and when treating the anterior field with an ultrasonic scaler. This water remains on the inner surface of the suction port and the inner surface of the suction hose, and when the suction is stopped, it may drip under its own weight and stain the patient's clothes or the treatment table, which is unsanitary.

Further, if the amount of air sucked from the mouth is increased, the dust collection efficiency is increased by that much, but a large capacity blower cannot be installed in a medical office having a limited space. In addition, since the sucked air is released to the outside of the room, if the air volume becomes large, the air conditioning in the room may become difficult, and the air volume must be limited to a certain degree, and the effect was not always sufficient. .

The present invention solves the problems associated with the above-mentioned conventional device, prevents the liquid such as water and saliva from dripping from the suction port, and can also improve the suction efficiency. An object is to provide a liquid receiving member and a suction port to which the liquid receiving member is attached.

[0008]

[Means for Solving the Problems]

 According to the present invention, the above-mentioned object is from the lower peripheral edge of the suction port provided at the tip of the suction hose connected to the vacuum device for sucking dust or the like emitted from the oral cavity of the patient under medical treatment to the front of the suction port. This can be achieved by employing a drip liquid receiving member which is mounted so as to project to and has a layer made of a water absorbing material on at least the upper surface. In this case, the means for attaching the drip liquid receiving member is provided on the suction port side.

Further, the above object can be achieved by providing an attachment portion on the drip liquid receiving member and attaching the attachment portion to the suction port.

Alternatively, the above object can be achieved by providing both the dropping liquid receiving member and the suction port with a mounting portion and a holding portion that cooperate with each other.

[0011]

[Action]

 In the present invention having the above-described structure, the drip liquid receiving member is attached to the lower peripheral edge of the suction port and protrudes in front of the suction port.

When used in such a state, even if water, saliva or the like drips from the peripheral portion of the lower inner surface of the suction port, there is a drip liquid receiving portion having a layer made of a water absorbing material on the upper surface. There is a material and it is absorbed by the member. Then, at the end of the medical treatment, it is removed and a new drip liquid receiving member is attached in preparation for the next medical treatment of the patient.

Further, since the drip liquid receiving member largely protrudes forward from the lower peripheral edge of the suction port, it blocks the suction of air from below the suction port, and the air is large in the area above the suction port. Is sucked into. At the time of medical treatment, saliva, cutting powder, etc. tend to scatter upwards, and the air flow that has been sucked in large amounts in the upper region effectively guides these into the suction port.

Thus, saliva or the like that is dripped from the suction port is captured by the drip liquid receiving member, and the cutting powder or the like of the spattered saliva is effectively sucked to the suction port.

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 is a suction port called a suction hood. The suction port 1 is formed between a hood portion 2 whose cross section in a plane including an axis forms a part of a cone, a cylindrical connecting portion 3 provided at a rear portion, and between the hood portion 2 and the connecting portion. And a filter unit 4.

The hood portion 2 has a shape that widens toward the front and is normally made of a transparent plastic material so that it can be observed from the outside. The connecting portion 3 has an inner diameter suitable for being connected to a suction hose 5 provided on a vacuum device (not shown), and engages with a locking projection (not shown) provided on the suction hose. An L-shaped groove 3A is formed. The filter portion 4 has a lattice shape so that foreign matter is not sucked into the suction hose 5 side.

The dripping liquid receiving member 6 is curved in a substantially semi-cylindrical shape, and has a layer of a water-absorbent material, for example, a fibrous material such as paper, on at least the upper surface (the curved inner surface in the figure). On the inner surface of the drip liquid receiving member 6 on the rear end side, a band-shaped adhesive material layer 7 is provided as a mounting portion, and a release paper 8 is provided thereon. The dropping liquid receiving member is not limited to the shape shown in the figure, and it is essential only that the dropping liquid receiving member be attached to the suction port 1 so as to project forward from the suction port 1.

As a preferred form of the drip liquid receiving member 6, the front end side edge portion 9 has a concave shape inward in the axial direction, and has a shape convenient for contacting the jaw of the patient. A plurality of rib portions 10 are formed on the side portions for reinforcing the entire structure. Further, as a preferred form, a concave portion 11 is formed in the central portion of the bottom portion so that even if a large amount of dropped liquid enters, it can be temporarily stored.

The material, thickness and the like of the dropping liquid receiving member 6 are determined in consideration of the amount of absorption and strength of the dropping liquid. Further, when the absorption amount is large, a non-water absorbing material layer may be formed on the lower surface.

In the dropping liquid receiving member 6 of this embodiment, the release paper 8 is peeled off and the adhesive is held on the lower surface of the lower front edge of the suction port as shown in FIG. Then, the jaw C of the patient is brought into contact with the concave front end side edge portion 9 of the dropping liquid receiving member 6. In this state, medical treatment is performed while sucking air from the suction port 1.

The saliva, cutting powder, etc. sucked during the medical treatment passes through the filter portion 4 and is guided into the suction hose 5, but a part of the saliva adheres to the inner surface of the suction port 1 and is condensed and liquefied. When the amount of the liquid becomes large, especially when the suction is stopped, the liquid easily flows down the inner surface of the suction port 1 and reaches the edge portion and drip. In this embodiment, since the liquid drop receiving member 6 is attached to the suction port 1, the liquid to be dropped is received by the liquid drop receiving member 6 and absorbed by the water absorbent material on the upper surface. Then, even if the dropping amount is large, in the case of the present embodiment, it is temporarily stored in the concave portion 11 and is gradually absorbed in the peripheral portion without flowing out. Upon completion of medical treatment, the drip receiving member 6 is removed and replaced with a new one in preparation for the next patient. In that case, the pressure-sensitive adhesive layer 7 is desired to be one in which the pressure-sensitive adhesive does not adhere and remain on the surface of the suction port.

When the dropping liquid receiving member 6 of this embodiment is attached, the air flowing into the suction port 1 is largely blocked by the dropping liquid receiving member 6 in the lower part, and as shown in FIG. Is sucked into. As a result, saliva, cuttings, etc. tend to scatter upward, but suction in particular in that area is strengthened. Therefore, the effect of using the suction device is improved accordingly.

Further, in the present embodiment, the mounting portion provided on the dropping liquid receiving member may be a clip member that holds the periphery of the suction port instead of the adhesive layer, or a rear portion of the dropping liquid receiving member. You may make it form the fitting groove which receives the periphery of a suction opening at the periphery.

Furthermore, when an adhesive layer is used for the attachment portion, as shown in FIG. 3, the rear portion of the drip liquid receiving member 6 is extended and the finger portion 12 extending along the circumferential direction of the suction port 1 is provided. If it is formed and the pressure-sensitive adhesive layer 13 is provided on the inner surface of the end in the circumferential direction, the adhesive layer 13 can be attached so as to cover the outer surface of the suction port 1, and a doctor or the like can set and move the position of the suction port 1. Even if the outer surface of the suction port 1 becomes dirty when it is gripped, the suction port 1 is always kept clean by replacing the drip liquid receiving member 6.

In the embodiment shown in FIGS. 1, 2, and 3, the drip liquid receiving member 6 has an adhesive layer 7; 13 on the inner surface as a mounting portion, and the suction port 1 is attached by this mounting portion. However, the present invention is not limited to this. For example, the drip liquid receiving member may not have the mounting portion, but may have the holding portion on the suction port side. As shown in FIG. 4, an elastic pinching portion 14 may be provided to insert the rear edge of the dropping liquid receiving member into the lower edge of the suction port 1 and elastically pinch it. Alternatively, as shown in FIG. 5, a plurality of pointed projections 15 may be provided on the outer surface of the suction port 1 and the drip solution receiving member may be attached thereto so as to be inserted therein.

Further, the drip liquid receiving member may be provided with a mounting portion and the suction port may be provided with a holding portion, respectively, so that both can cooperate to be mounted. For example, the rubber ring can be locked by providing a rubber ring or the like (not shown) on the dripping liquid receiving member and providing a locking projection 16 on the suction port 1 as shown in FIG.

[0028]

[Effect of device]

 As described above, according to the present invention, since the drip liquid receiving member that protrudes forward of the suction port is attached to the lower peripheral edge of the suction port, liquid such as saliva drip from the suction port is absorbed and a new liquid is added for each medical examination. It can be exchanged for something, and the effect of always ensuring a hygienic condition is obtained. Furthermore, since air is strongly sucked from the upper side of the suction port, saliva, cutting powder, etc., which are not scattered in the air, are effectively captured.
