Description

Multifunctional suction head for sucking and removing oral spray saliva

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to a multi-functional suction head for absorbing oral cavity droplet saliva.

Background

Aerosols are colloidal dispersions of small particles of solids or liquids dispersed and suspended in a gaseous medium. The droplets formed by high speed hand-held instruments, air-water guns, ultrasonic tooth-cleaning instruments, and the like, are typically 5um or less in diameter and are converted into droplets with nuclei suspended in the air in the form of aerosols for up to half an hour or more. These generated aerosols and aerosols are diffused in the air and even splashed into the face and eyes of medical staff, and when oral operation is carried out, the splashed droplets can be transmitted for 2.1 meters at most, and all surfaces of the whole oral office are possibly polluted by splashed substances, so that the risk of infection of infectious diseases through transmission paths such as saliva, blood, cooling water and aerosols is increased.

However, oral care is unique in that patients are not usually tested for infectious diseases before outpatient oral care, and oral care personnel need to be in close face-to-face contact with the patients for a long time. Outpatient service is the place where patients mostly attend medical care, and the patients hide or do not find themselves to have potential infectious diseases, which may cause outbreak.

The saliva suction technology is a technology for sucking and removing water mist, debris, blood, cooling water and saliva in the oral cavity by using a saliva suction device in the oral cavity outpatient treatment process so as to keep the operation visual field clear and assist the operation to be smoothly carried out. The saliva suction pipe is a common saliva suction device for oral cavity. The dental comprehensive treatment table is provided with a strong suction pipeline and a weak suction pipeline, and water, saliva and the like in oral operation can be sucked after the dental comprehensive treatment table is provided with corresponding suction pipe heads. At present, the strong pipette head used clinically is universal, as shown in figure 1, the shape of a duckbill is hard, saliva in a suction port is large, the area is too small when the droplet aerosol is sucked, and the diffusion of the droplet aerosol is difficult to effectively reduce. As shown in figure 2, the weak pipette tip is mainly used for sucking water, saliva and blood generated in oral diagnosis and treatment, and a disposable inlet hose is mostly used. When the weak suction pipeline is blocked by dirt, the pipeline is blocked due to poor water source quality, the weak suction can generate insufficient suction, and meanwhile, the strong suction pipe head is large, so that vomit, sensitivity or other adaptation can be easily caused during operation in the oral cavity, the absorbing of spray generated in the operation is not very effective, and spray blood can be formed to splash to the periphery.

Although an outdoor electric suction system is used for sucking and removing droplets and aerosol specially in clinic, the suction force is large, the suction system needs to be purchased separately, the volume is large, the noise is large, the equipment is expensive, a certain field needs to be occupied, the popularization difficulty is large, and meanwhile, water drops are easy to form at the edge of the suction head and are gathered and dropped.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve the technical scheme who above-mentioned technical problem took and be: a multifunctional suction head for sucking saliva in oral cavity is characterized in that: the multifunctional suction head comprises a funnel-shaped suction hopper, a connecting pipe extends out of the bottom of the suction hopper, an adapter is connected to the connecting pipe in a sealing mode, the inner diameter of the adapter is matched with the outer diameter of the connecting pipe, at least two outer diameters are arranged on the outer portion of the adapter, and the adapter is matched with a strong suction pipe or a negative pressure aspirator connecting pipe of a dental comprehensive treatment table respectively.

According to the scheme, the inner diameter of the connecting pipe is the same as the outer diameter of the disposable saliva sucking pipe.

According to the scheme, the top of the suction hopper is provided with a protruded edge, the edge is internally provided with a groove, and one part of the groove is connected with a water mist flow guide pipe communicated with the connecting pipe.

According to the scheme, the water mist guide pipe is arranged along the inner wall of the suction hopper and extends into the connecting pipe.

According to the scheme, the top of the suction hopper is connected with the protective baffle movably connected with the edge of the suction hopper, so that the protective baffle can slide along the edge of the suction hopper.

According to the scheme, the protective baffle is connected with the top of the suction hopper through the detachable sliding connecting piece.

According to the scheme, the outer part of the adapter is of a step structure or a circular truncated cone structure.

The utility model has the advantages that:

1. through the suction funnel that adopts the infundibulate, the adaptation is equipped with the adapter of multiple external diameter, can be applicable to the strong suction tube or the electronic negative pressure aspirator connecting pipe of various pipe diameters in the dentistry comprehensive treatment platform, funnel shaped suction head carries out the water smoke when removing on strong suction tube connection simultaneously, also can insert the suction funnel with the disposable saliva suction tube that clinical commonly used, reach and absorb intraoral blood, the purpose of saliva and water, have multiple use.

2. According to the condition, the protection plate is removed or installed, and the protection plate is adjusted to be in a proper state, so that the shielding range is adjusted. Not only is convenient for clinical operation; can be detached and replaced at any time, or only the suction hopper is left without a protective baffle, thus being suitable for different types of operation in different ranges. The final treatment of the protective baffle uses common disinfectants such as ethanol and the like to disinfect the mirror surface of the mask, which is simple and convenient and avoids cross infection. The use of the protective baffle prevents saliva, blood, water, debris and the like which are splashed out of the oral cavity during treatment from infecting medical staff, ensures safety and simultaneously ensures clear visual field of a doctor in the operation process.

3. The inner and outer edges of the funnel-shaped suction hopper form bulges, so that the sucked water mist can be prevented from dropping from the edges of the funnel under the action of gravity due to insufficient suction force of the suction pipe. A small hollow pipeline opening is designed at the edge of the leak, the pipeline enters the pipe body along the funnel, the opening is formed in the connecting pipe of the funnel, and the gathered water mist can be effectively absorbed into the suction pipe through the pipeline at the edge. The negative pressure intensity of the suction pipe is adjusted, so that blood and saliva in the oral cavity of a patient can be cleaned, liquid gas and aerosol sprayed by the high-speed turbine can be washed away, or all microorganisms which are released along with ultrasonic vibration and suspended in the air can be cleaned, the environment of a consulting room can be kept clean, the health of the patient and medical care personnel can be guaranteed, and the comfort level of the patient can be improved.

4. The strong suction pipe connects can design flexible soft silica gel adapter, and the usable adapter of infundibulate suction hopper is connected, and the disposable saliva tube accessible flare opening of inhaling that clinical commonly used simultaneously inserts the funnel connecting pipe, and the three forms closely and links up, effectively guarantees the negative pressure, and then reaches effective absorption droplet and saliva etc..
