Description

Technical Field

[0001] The present invention relates to a device for cleaning the oral cavity. Background Art

[0002] In order to provide patients with more convenient and effective oral care and prevent respiratory tract infections, the current clinical oral care implementation methods are as follows:

[0003] 1. Scrub with cotton balls: disposable oral care package: equipped with disposable plastic flat tweezers and cotton balls; the other is metal flat tweezers. When using, use the flat tweezers to pick up the cotton balls and scrub the various parts of the teeth and the mouth. This operation is more cumbersome, and the cotton balls cannot completely wrap the flat tweezers, causing the flat tweezers to touch the mouth and teeth, causing discomfort, or knocking sounds, and even damage to the oral mucosa.

[0004] 2. Scrubbing with a cotton swab: This method has the risk of the cotton ball falling off the cotton swab.

[0005] At the same time, the biggest problem with the above two cleaning methods is that it is difficult to clean the inner side of the teeth and the gaps between the teeth in the mouth, resulting in food residues and oral secretions remaining, which are easy to breed bacteria. The liquid produced during the operation needs to be spit out by the patient, which can easily cause choking and suffocation risks for critically ill patients. Summary of the invention

[0006] In view of this, the present invention provides an oral cleaning device, which can clean the patient's oral cavity, especially the inner side of the teeth, conveniently and quickly.

[0007] In order to solve the above technical problems, the technical solution of the present invention is to adopt an oral cleaning device, including a brush head and a brush handle; the brush head and the brush handle are respectively arranged at the front and rear ends of the connecting rod, and the brush head is divided into two upper and lower parts, which are respectively fixed on the upper and lower driving shafts vertically arranged with the connecting rod by connecting plates; the driving shaft is provided with teeth; it also includes an inner tube coaxial with the connecting rod, and an outer tube is arranged outside the inner tube; the outer tube can slide back and forth along the inner tube; the outer walls on the upper and lower sides of the front end of the outer tube are provided with axially arranged teeth meshing with the teeth on the driving shaft; the brush handle includes an inner handle and an outer handle; the outer handle is a frame, 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 passes through the inner handle and the outer handle; a reset spring is arranged between the inner handle and the outer handle.

[0008] As an improvement, the inner handle is rod-shaped, and the inner cavity of the outer handle is rectangular; grooves are provided on the upper and lower inner walls of the inner cavity of the outer handle, and the two ends of the inner handle are clamped in the grooves.

[0009] As a further improvement, the brush head comprises an arc-shaped mounting plate, and the mounting plate is covered with soft bristles. The arc-shaped brush head shape is more closely matched to the shape of the inner side of the teeth.

[0010] As another further improvement, a flushing water pipe is arranged inside the inner tube, and the gap between the flushing water pipe and the inner tube is a suction chamber for negative pressure suction. The cleaning water in the oral cavity can be extracted while flushing, and the gap between the inner tube and the flushing water pipe is used as the suction chamber, which reduces the arrangement of pipes and flushes inside and sucks outside.

[0011] As an improvement, the flushing water pipe is connected to a flushing water source, and the suction chamber is connected to a negative pressure suction device.

[0012] As an improvement, the inner handle surface is provided with a depression for easy finger gripping, so as to facilitate gripping and driving the inner handle to slide.

[0013] The benefit of the present invention lies in that: the oral cleaning device with the above structure drives the brush head at the front end to perform a flipping motion through the brush handle, which is used to clean the inner side of the teeth, and at the same time, the food residues and cavity secretions washed away are taken away by the flushing water. The entire cleaning process is simple and fast, and the method of driving the brush head by pressing the inner handle is also relatively easy, which greatly reduces the labor intensity of medical staff. Since there is no stimulation from sharp objects such as tweezers or cotton swabs, and the flushing water does not need to be spit out by the patient during the operation, the comfort during cleaning is improved and the risk of choking and suffocation is reduced.

[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with specific implementation methods.

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the present invention includes a brush head 2 and a brush handle; the brush head 2 includes an arc-shaped mounting plate 21, and the mounting plate 21 is covered with soft hair 23. The brush head 2 can be set to several specifications for patients with different cavity sizes. The brush head 2 and the brush handle are respectively arranged at the front and rear ends of the connecting rod 1. The brush head 2 is divided into two upper and lower parts, and is respectively fixed to the upper and lower driving shafts 24 arranged vertically with the connecting rod 1 by using the connecting plate 21; the driving shaft 24 is provided with teeth; it also includes an inner tube 4 coaxial with the connecting rod, and the inner tube 4 is provided with an outer tube 3; the outer tube 3 can slide forward and backward 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 that mesh with the teeth on the driving shaft 24; the brush handle includes an inner handle 6 and an outer handle 5; the outer handle 5 is a frame, and the inner handle 6 can slide forward and backward 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 passes through the inner handle 6 and the outer handle 5; a reset spring is provided between the inner handle 6 and the outer handle 5.

[0021] The inner handle 6 is rod-shaped, and the inner cavity of the outer handle 5 is rectangular; grooves are provided on the upper and lower inner walls of the inner cavity of the outer handle 5, 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 for easy finger gripping.

[0022] A flushing water pipe 9 is provided in the inner tube 4, and the gap between the flushing water pipe 9 and the inner tube 4 is a suction chamber for negative pressure suction. The flushing water pipe 9 is connected to a flushing water source, and the suction chamber is connected to a negative pressure suction device. Preferably, the inner tube 4 and the flushing water pipe 9 extending out of the outer handle 5 are connected with a joint 8, and the negative pressure suction device and the flushing water source are connected by the joint 8.

[0023] When in use, insert the brush head 2 into the patient's oral cavity. The operator holds the thumb behind the outer handle 5, and the other four fingers pass through the gap between the inner handle 6 and the outer handle 5 (the part located in front of the inner handle 6). By holding the inner handle 6 tightly, the outer tube 3 is pulled to slide forward and backward, and the teeth at the front end of the outer tube 3 are driven to rotate the drive shaft 24 engaged therewith to drive the brush head to flip. After unloading, the outer tube 3 slides forward under the action of the reset spring 7 to reset the brush head 2. Repeat the above actions to clean the inner side of the patient's teeth.

[0024] The above are only preferred embodiments of the present invention. It should be noted that the above preferred embodiments should not be regarded as limiting the present invention, and the protection scope of the present invention should be based on the scope defined by the claims. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the spirit and scope of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
