Description

Oral saliva aspirator head

Technical Field

The application relates to the technical field of medical equipment, in particular to an oral saliva aspirator head.

Background

In the oral cavity diagnosis and treatment process, due to the rotation of the high-speed turbine and the vibration resonance of the ultrasonic tooth cleaner, the compressed air and the water are combined to be atomized in the circulating operation process, and a large amount of aerosol and spray containing microorganisms such as saliva, blood, dental plaque, bacteria, viruses, fungi and the like are generated. These droplets and aerosols contain a large number of pathogenic microorganisms, and in particular the particles contained in the aerosols, which are less than fifty microns in diameter, not only have a strong penetration, but also tend to colonize the small branches of the lungs, and are considered to be the most potentially dangerous particles for inhalation into the lungs of a transmitted disease. Research shows that during oral treatment, the circumferential range which is drawn by taking the oral cavity of a patient as the center and taking the length of one meter as the radius is the area with the most serious aerosol pollution. Oral treatment is prone to aerosol transmission due to the specificity of the treatment space and the equipment. Currently, pathogenic microorganisms that may be transmitted by aerosol include SARS coronavirus, hepatitis b virus, hepatitis c virus, Human Immunodeficiency Virus (HIV), and the like. Because the droplets and the aerosol cannot be removed in time, the droplets and the pathogenic microorganisms contained in the aerosol pose a potential threat to the safety and health of patients and medical staff.

The department of stomatology adopts negative pressure suction system to absorb water smoke, spray and aerosol produced during operation, and the system is divided into strong suction system and weak suction system. The strong suction and the weak suction pipeline of present dental chair configuration are divided independent pipe-line system, and the suction of weak suction is little, can gently siphon away rivers and saliva at the bottom of patient's mouth, and patient's uncomfortable is little, and weak straw is soft straw, and the bending wantonly can hang and need not the external force cooperation at patient's angle of mouth and can facilitate the use, also can use by the nurse cooperation. The strong suction pipe has a large suction force, and is placed at the bottom of the mouth of a patient to cause strong discomfort, so that the strong suction pipe is generally placed around a high-speed mobile phone, a dental scaler head and the like to directly suck away water mist generated during operation, is not used for sucking water flow at the bottom of the mouth, cannot suck water flow at the bottom of the mouth, and must be used by a nurse in four-handed operation. The strong suction can reduce the spread of water mist and more effectively reduce the spread of germs.

The weak suction can only suck away the water flow at the bottom of the mouth, and can not effectively suck the water mist, the spray and the aerosol generated during the operation. The strong suction can suck water mist, spray, aerosol and the like generated during operation to reduce pathogen transmission, but the saliva suction noise under the strong negative pressure is far higher than that under the weak negative pressure, and investigation shows that 56.8 percent of medical workers are unwilling to use due to the excessive noise of the strong saliva suction.

the main pipeline 10 is communicated with the auxiliary pipeline 20, and the inner wall of the main pipeline 10 is provided with a silencing structure.

Wherein the sound deadening structure may be a sound deadening hole 13. In detail, the muffling holes 13 are blind holes formed in the inner wall of the main pipe 10, a plurality of muffling holes 13 are distributed in the main pipe 10, and when suction is performed, sound waves of noise are agitated in the main pipe 10 and are interfered by the muffling holes 13 to superpose noise, so that the energy of the noise is mutually offset and loss is reduced, and the noise decibel is reduced.

Optionally, a spring or a spring plate is disposed on the inner wall of the main pipe 10 to serve as a noise reduction structure for interfering with the superposition of sound waves, and the noise is also attenuated by absorbing the energy of the sound waves and releasing the energy in a vibration manner, so as to reduce the energy of the noise.

Optionally, a spring may be additionally arranged in the silencing hole 13 to interfere and weaken noise together, so as to reduce the noise generated during the operation of the main pipe 10 as a whole.

Specifically, in the present embodiment, the secondary pipe 20 is a flexible hose. The telescopic hose can be convenient for on the one hand according to the degree of depth at the bottom of the mouth, adjust the holistic length of auxiliary duct 20, on the one hand can also conveniently accomodate, when not using, the space that the auxiliary duct 20 of shrink occupied is few, still is convenient for fix with trunk line 10.

It will be appreciated that the secondary duct 20 may also be designed directly as a non-collapsible hose, facilitating the change of angle. Optionally, the secondary conduit 20 may also be designed as a rigid conduit with a certain curvature, and when the patient bites the secondary conduit 20 at the corner of the mouth, the suction port of the secondary conduit 20 may protrude into the mouth bottom, so as to ensure the suction of the substance such as water flow and saliva at the mouth bottom.

Wherein the occlusion opener 30 can be bound on the main pipe 10 together with the auxiliary pipe 20 and then unbound when in use, so as to reduce unnecessary space occupation.

It should be noted that the middle of the secondary pipe 20 does not mean that the mouth gag 30 must be in the middle position in the length direction of the secondary pipe 20, but means that the mouth gag 30 is in a non-end position with respect to being arranged at both end portions. This ensures that a portion of the secondary conduit 20 can be inserted into the mouth.

Of course, the bite-block mouth gag 30 of this embodiment is removably connected with the secondary conduit 20. By disassembling and assembling the occlusion mouth gag 30, when the model of one occlusion mouth gag 30 needs to be replaced, other occlusion mouth gag 30 can be directly replaced without additionally replacing the whole set of oral cavity saliva aspirator head, thereby saving the cost to a certain extent. In addition, the position of the occlusion mouth gag 30 on the secondary pipeline 20 can be changed according to the depth of the mouth bottom position, so that the length of the part of the secondary pipeline 20 extending into the oral cavity is adjusted to adapt to the oral cavity environment of different patients.

It is understood that for patients with special requirements on the opening degree, the included angle between the two can be designed to be a right angle or even an obtuse angle so as to meet the requirements of special opening degrees.

This allows the overall profile of the bite opener 30 to more closely approximate the configuration of the space between the upper and lower molars as the patient opens. The first occlusion part 31 and the second occlusion part 32 can respectively abut against the upper and lower teeth of the patient, and the distance between the upper and lower teeth which can be spread can be different according to different included angles. Selecting a suitable angle for the occlusion opener 30 for different patients makes the basic operating environment during treatment more ideal, which is beneficial to better complete the treatment. It will be appreciated that different treatment regimens may require different degrees of openness for the same patient, and that bite openers 30 of suitable size may be selected accordingly to provide the patient with the desired openness for the treatment.

Wherein, the more ideal basic operating environment means that the internal and external environments of the oral cavity of the patient are more convenient for medical staff to carry out treatment operation when carrying out oral treatment operation.

More specifically, the first engaging portion 31 and the second engaging portion 32 enclose an installation hole 33, and the sub-pipe 20 is inserted into the installation hole 33. The installation hole 33 is provided to better utilize the biting force of the patient and to keep the position of the sub-tube 20 fixed.

The secondary conduit 20 may then be further adjusted to access the bottom of the patient's mouth.

In the present embodiment, the first engaging portion 31 and the second engaging portion 32 each have a limiting groove 34. The retention slot 34 may better accommodate the upper or lower teeth and may be more snug when engaged. In addition, the occlusion mouth gag 30 is not easy to slide in the treatment process due to the fact that the occlusion mouth gag can be occluded into the groove, and the phenomenon that the auxiliary pipeline 20 falls off due to the lower jaw movement of a patient is avoided.
