Description

Oral cavity cleaning device

Technical Field

The present invention relates to a device for cleaning the oral cavity.

Background

Provides more convenient and effective oral care for patients and prevents respiratory tract infection. The current clinical oral care practice is as follows:

1. cotton ball scrubbing: disposable oral care package: preparing disposable plastic flat forceps and cotton balls; the other is metal flat forceps. When in use, the flat forceps are used for clamping and taking the cotton balls to scrub all parts of the teeth and the oral cavity respectively. The operation is complicated, and the cotton ball can not completely wrap the flat forceps, so that the flat forceps touch the oral cavity and the teeth to cause discomfort, or knocking sound occurs, and even the oral mucosa is damaged.

2. Cotton swab scrubbing: this method risks the cotton ball falling off the swab.

Meanwhile, the two cleaning modes have the biggest problem that the inner side surfaces and the tooth gaps of teeth in the oral cavity are difficult to clean, so that food residues and oral secretion residues are caused, and bacteria are easy to breed. The liquid generated in the operation needs to be spit by the patient, and the patient with serious illness is easy to be choked and suffocated.

Disclosure of Invention

In view of this, the present invention provides an oral cavity cleaning device, which can conveniently and rapidly clean the oral cavity of a patient, especially the inner side of teeth.

In order to solve the technical problems, the technical scheme of the invention is that an oral cavity cleaning device is adopted, which comprises a brush head and a brush handle; the brush head and the brush handle are respectively arranged at the front end and the rear end of the connecting rod, the number of the brush heads is two, and the two brush heads are respectively fixed on an upper driving shaft and a lower driving shaft which are vertically arranged with the connecting rod by utilizing connecting plates; the driving shaft is provided with teeth; the connecting rod is sleeved outside the outer pipe; the outer pipe can slide back and forth along the inner pipe; the outer walls of the upper side and the lower side of the front end of the outer pipe are provided with axially arranged teeth which are meshed with the teeth on the driving shaft; the brush handle comprises an inner handle and an outer handle; the outer handle is a frame body, and the inner handle can slide back and forth in the inner cavity of the outer handle; the rear end of the outer tube is fixed on the inner handle, and the rear end of the inner tube penetrates through the inner handle and the outer handle; and a return spring is arranged between the inner handle and the outer handle.

As an improvement, the inner handle is rod-shaped, and the inner cavity of the outer handle is rectangular; the upper inner wall and the lower inner wall of the inner cavity of the outer handle are provided with grooves, and two ends of the inner handle are clamped in the grooves.

As a further improvement, the brush head comprises an arc-shaped mounting plate, and the mounting plate is covered with soft bristles. The shape of the arc-shaped brush head is more fit with the shape of the inner side surface of the teeth.

As another further improvement, a flushing water pipe is arranged in the inner pipe, and a gap between the flushing water pipe and the inner pipe is a suction cavity for negative pressure suction. The oral cavity cleaning water can be pumped while the oral cavity cleaning water is flushed, and the gap between the inner pipe and the flushing water pipe is used as a suction cavity, so that the arrangement of pipelines is reduced, and the oral cavity cleaning water can be flushed and sucked outwards.

As an improvement, the flushing water pipe is connected with a flushing water source, and the suction cavity is connected with a negative pressure suction device.

As an improvement, the surface of the inner handle is provided with a depression convenient for fingers to hold. The inner handle is convenient to hold and drive to slide.

The invention has the advantages that: the oral cavity cleaning device with the structure drives the brush head at the front end to do turnover motion through the brush handle, is used for cleaning the inner side surface of teeth, and takes away food residues and cavity secretions which are cleaned by utilizing flushing water. The whole cleaning process is simple and quick, the mode of driving the brush head by pressing the inner handle is easy, and the labor intensity of medical staff is greatly reduced. Because no sharp objects such as tweezers or cotton swab sticks are used for stimulation, and in addition, the washing water does not need to be discharged by a patient in a matching way, the comfort in washing is improved, and the choking risk are reduced.

Detailed Description

In order that those skilled in the art will better understand the technical solutions of the present invention, the present invention will be further described in detail with reference to the following embodiments.

As shown in fig. 1, 2, 3 and 4, the invention comprises a brush head 2 and a brush handle; the brush head 2 comprises an arc-shaped mounting plate 21, and the mounting plate 21 is covered with soft bristles 23. The brush head 2 can be set into a plurality of specifications aiming at patients with different cavity sizes. The brush head 2 and the brush handle are respectively arranged at the front end and the rear end of the connecting rod 1, the brush head 2 is divided into an upper brush head and a lower brush head, and the upper brush head and the lower brush head are respectively fixed on an upper driving shaft 24 and a lower driving shaft 24 which are arranged vertically to the connecting rod 1 by utilizing connecting plates 21; the driving shaft 24 is provided with teeth; the connecting rod is characterized by further comprising an inner tube 4 coaxial with the connecting rod, and an outer tube 3 is sleeved outside the inner tube 4; the outer tube 3 can slide back and forth along the inner tube 4; the outer walls of the upper and lower sides of the front end of the outer tube 3 are provided with axially arranged teeth which are meshed with the teeth on the driving shaft 24; the brush handle comprises an inner handle 6 and an outer handle 5; the outer handle 5 is a frame body, and the inner handle 6 can slide back and forth in the inner cavity of the outer handle 5; the rear end of the outer tube 3 is fixed on the inner handle 6, and the rear end of the inner tube 4 penetrates through the inner handle 6 and the outer handle 5; and a return spring is arranged between the inner handle 6 and the outer handle 5.

The inner handle 6 is rod-shaped, and the inner cavity of the outer handle 5 is rectangular; the upper inner wall and the lower inner wall of the inner cavity of the outer handle 5 are provided with grooves, and the two ends of the inner handle 6 are clamped in the grooves. The surface of the inner handle 6 is provided with a depression convenient for fingers to hold.
