Description

Dental portable unit

[0001] The present invention relates to a portable dental unit that enables treatment in an external environment by easily and safely moving equipment necessary for dental treatment.

[0002] The proportion and absolute number of people aged 65 and over are rapidly increasing worldwide. Given the link between aging and functional dependency, the number of older adults returning to their hometowns and institutionalized older adults is also expected to increase. Studies show that aging populations disproportionately experience a variety of oral health problems related to limited physical and cognitive function, systemic conditions, and reduced access to oral health services. As more people retain their natural teeth into old age, this situation could pose significant challenges to current dental care systems. One solution could be an alternative model of mobile dental care, called "Portable Dentistry," designed to provide care for those unable to access dental care on their own.

[0003] In this type of dental care service, a dental care team travels to patients in their homes or nursing homes, providing dental care using portable dental equipment.

[0004] However, the lack of portable dental equipment often limits the scope of treatment available. Furthermore, because dental teams typically cover a wide area, timely follow-up care is often lacking, which can be particularly problematic when postoperative complications arise.

[0005] Another challenge with portable dentistry is the need to move heavy dental equipment. While this is an inevitable part of portable dentistry, because each visit's requirements can vary, carrying a full set of dental equipment may not be necessary.

[0006] This can be addressed through careful step-by-step planning and preparation of portable equipment packages, including basic portable kits and pre-prepared individual kits. Portable dental equipment can also be prepared in advance for different treatment types, such as examination, prevention, prosthodontics, surgery, restorative, and periodontal kits.

[0007] The present invention aims to provide a portable dental unit that is configured to connect various dental treatment tools so that dental treatment can be performed effectively in an external environment and that can protect the equipment when moved.

[0008] A dental portable unit according to one embodiment of the present invention may be configured to include, as described below, a holder for holding dental tools, a first support frame for fixing the holder, a driving unit for driving the dental tools, and a receiving unit having a predetermined thickness, width, and height to accommodate the holder and the first support frame, and having an opening and closing structure through an opening and closing unit provided at one end.

[0009] A dental portable unit according to at least one of the various embodiments of the present invention has the advantage of being formed with a structure that is convenient to move, making it convenient to move in an external environment, stably accommodating various tools to respond to various external situations, and being able to perform more stable and accurate treatment by being able to incorporate or detach a display device.

[0022] Figure 2 is a diagram showing the usage status of a dental portable unit according to one embodiment of the present invention.

[0023] At this time, Fig. 1 can be seen as showing a first state of a dental portable unit according to an embodiment of the present invention, and Fig. 2 can be seen as showing a second state of a dental portable unit according to an embodiment of the present invention. Here, the first state can refer to a state before using the dental portable unit, i.e., before unfolding, and the second state can refer to a state in which the dental portable unit is unfolded for use.

[0024] As seen in FIGS. 1 and 2, the dental portable unit according to the present invention may include a machine part (100), a box part (200), and a lid part (150).

[0025] Here, the box portion (200) can be placed at the bottom of the machine portion (100). And the lid portion (150) can cover the upper portion of the machine portion (100).

[0026] The machine part (100) is a rectangular body with an upper and lower opening, and the upper part is covered with a machine top plate (104). After removing a certain area of ​​the machine top plate (104), a rectangular machine room (inside the machine part) with an upper part opened is combined, and an operation panel (105) can be combined to form a partially inclined surface in one area of ​​the machine top plate (104). A plurality of operation buttons (106) can be formed on the inclined surface of the operation panel (105).

[0027] Inside the machine room, a control block and a control panel can be installed to supply air and water to dental treatment tools, and to supply air and water to a specific tool when that tool is in use.

[0028] In the machine room, tools such as high-speed rotation tools, low-speed rotation tools, scaling tools, and tools for supplying air and water can be installed so that a variety of dental treatment tools can be used, and a supply line (122) that includes a power line can be connected as needed.

[0029] A tool joint (not shown) for mounting a dental treatment tool may be formed at the other end of the supply line (122) connected to the machine room. In addition, a control pedal (102) may be connected so that the tool can be operated by stepping on it.

[0030] At the end of the slide member, which is inclinedly supported by a support bar connected to the machine float (104) from the bottom of the machine room, a stand (120) can be formed so as to be able to slide along the slide member.

[0031] The above-mentioned holder (120) may be formed with a tool mounting hole (121) so that a tool coupling hole (not shown) installed at the end of a plurality of supply lines (122) can be mounted. A dental treatment tool can be mounted on the tool mounting hole (121) after being mounted on the tool coupling hole (not shown).

[0032] A lid (150) is formed to cover the upper part of the machine part (100). A handle (111) is formed on the upper part of the lid (150) to enable the dental portable unit to be held and moved, and a dial-type locking device can be installed on the front so that it can be locked by being combined with the front of the machine part (100). In addition, a detachable hinge (not shown) is installed on the rear so that the lid (150) can be completely removed from the machine part (100) when opening the lid (150) for treatment.

[0033] A square tray (108) can be placed or combined on the top or side of the machine injury plate (104) so ​​that various materials, medicines, tools, etc. can be placed and used during treatment.

[0034] A leg section (300) can be installed on both inner sides of the machine section (100).

[0035] The leg part (300) is formed as a pair of two circular bars (302) that have a smaller diameter and form a single section. The circular bars (302) are connected by a connecting bar (303), and the connecting bar (303) can be connected to the leg handle (301) with a spring (304) therebetween. When the leg handle (301) is pulled, a ball (not shown) that supports the section of the circular bar (302) is removed, so that the circular bar can be folded.

[0036] The leg portion (300) connected to both inner sides of the machine portion (100) is connected and fixed to both inner sides of the box portion (200). The box portion (200) is in the shape of a square box with an open top, and when the leg portion (300) is folded and connected to the machine portion (100), it can provide a space into which a supply line (122) and an operating pedal (102) can be inserted.

[0037] Two hooks (201) are formed on the front and rear sides of the machine part (100) and the box part (200), respectively, so that the machine part (100) and the box part (200) can be joined together as one piece.

[0038] As shown in Fig. 1, the lid part (150), the machine part (100), and the box part (200) are formed as one piece by the locking device (107) and the hook (201), and when the handle (111) is used to move to a desired location, and after the hooks (201) on the front and rear are disassembled and the handle (111) is lifted, the leg part (300) can be automatically unfolded and fixed.

[0039] At this time, the holder (120) mounted on the upper part of the slide member and retracted inside can be prepared to move forward by gravity so that the tool can be placed thereon.

[0040] After this, after dismantling the dial lock, the handle (150) can be lifted and removed from the hinge, and the tray (108) can be placed on the machine top plate (104) or attached to its side.

[0041] Afterwards, the dental treatment can be completed by connecting the hose and a small compression pump that supplies compressed air. Meanwhile, the compression pump (illustrated in FIGS. 9 and 11-12) can be fixedly installed within the box section (200). For this purpose, a fixing pin or fixing member can be further formed within the box section (200).

[0042] After the treatment is finished, the lid (150) is closed by fitting it into the hinge (not shown), and then locked with a locking device. After organizing the operating pedal (102) and the supply lines (122), the stand (120) is pushed in, and the handle (111) is held and the leg handle (301) is lifted with the other hand, so that the leg (302) folds, and the machine part (100) and the box part (200) are combined to become a state as shown in FIG. 1 for movement again.

[0044] FIG. 4 illustrates a dental portable unit that can be combined with a display device (350) according to one embodiment of the present invention.

[0045] For dental treatment, it's crucial to accurately assess the patient's dental condition. While this can sometimes be assessed visually, in many cases, a more accurate assessment requires imaging, such as X-rays or CT scans.

[0046] Therefore, it can be seen that at least a display device (350) is essential for more effective dental treatment.

[0047] With the recent advancement in digital technology, display devices (350) have also become miniaturized.

[0048] Accordingly, a display device (350) can be mounted or combined with a dental portable unit according to one embodiment of the present invention.

[0049] In Fig. 3(a), a display device (350) according to one embodiment of the present invention is illustrated.

[0052] For example, in FIGS. 2 and 3(b), the lid (110) and the mechanical upper plate (104) can be replaced with a display device (350). Just as the lid (110) and the mechanical upper plate (104) are connected by a hinge to form an opening / closing structure, the display (360) and the operating unit (370) of the display device (350) according to one embodiment of the present invention can also be replaced because they have an opening / closing structure by a hinge.

[0053] The display (360) of the display device can be positioned at the location of the lid (110) of FIG. 3(b). The lid (110) described above can be closed when moved and opened after moving. Similarly, if the display (360) can be moved in a closed state, it has a structure that can be opened when in use.

[0054] The machine top plate (104) can be replaced by the operation unit (370) of the display device (350). At this time, the operation unit (370) may include the operation panel (105) and operation buttons (106) formed on the machine top plate (104) of FIG. 2 described above, or may include a corresponding configuration.

[0055] If the display device (350) includes only a display (360), only the lid (110) may be replaced with the display (360) or the display (360) may be mounted on the lid (110). In this case, the display (360) may also be controlled through the control panel (105) and control buttons (106) formed on the machine top plate (104).
