Description

A kind of dental spray gun for preventing water from splashing

Technical field

The utility model relates to a kind of medical instrument more particularly to a kind of type medical instrument for dental use.

Background technique

With the increasingly raising of national economy and living standard, the probability that oral problem occur in people is higher and higher, with this Oral hygiene and oral health are increasingly valued by people simultaneously.

Currently, doctor is using in the dental therapeutic tool course of work, it is often necessary to the devices such as use and treatment associated spray gun Tool assists in the treatment of.When treating to oral cavity, doctor reflects light into oral cavity generally by the mirror being worn on forehead In, by reflect into light can see affected part.But due to being reflected light, so in one bright light source of outside need, And the excessively bright eyes that can stimulate doctor of light source.And since reflective mirror is worn over forehead, so when the angle of adjustment reflected light The angle of doctor's rotational mirror or the angle of doctor's adjustment head are needed, can be brought inconvenience to the treatment of doctor.

Application No. is the Chinese patents of CN201310439102.9 disclosed on January 1st, 2014, disclose a kind of multi-functional Spray gun comprising gun body, gun body inside have accommodating space, is provided with airflow channel in accommodating space and separates with airflow channel The water stream channel of setting, airflow channel, water stream channel are connected with the nozzle being set in gun body, and spray gun further includes jet button And spraying button.

But when this spray gun being used to spray water patient's mouth, oral cavity space is limited, observes for convenience, the spray head of spray gun It is needed to maintain a certain distance apart from affected part, so being sprayed onto the water in affected part can splash, simultaneously because patient body is typically at this time Face upward the state of lying, in gapemouthed situation, the water splash can fall on the throat of patient, make patient condition reflect carry out gulp down Pharynx.Therefore a kind of spray gun for preventing water from splashing is needed, when cleaning to affected part, the water of ejection will not splash patient's throat Portion prevents patient from swallowing antihygienic water.

Utility model content

The purpose of this utility model is to provide a kind of dental spray guns for preventing the water for being sprayed onto affected part from flashing.

A kind of to achieve the above purpose, the technical solution of the present invention is: dental spray gun for preventing water from splashing, including Handle and spray head, spray head are fixed on handle, are fixed with jet pipe in handle and spray head, further include sewage collection equipment, negative pressure list The suction hose that member, water inlet pipe and one end are connect with sewage collection equipment, the suction hose other end protrude into spray head far from handle one end, spray Pipe is connect with water inlet pipe；Negative pressure unit includes shaft, impeller and blade, and shaft turns through jet pipe and suction hose side wall and with side wall Dynamic connection, impeller and blade are separately fixed at both ends of the shaft, and impeller is located in jet pipe, blade is located in suction hose；On handle Equipped with the control switch that jet pipe can be made to be connected to or disconnect with water inlet pipe.

When in use, spray head is protruded into oral cavity, and by spray head far from handle one end towards affected part, adjust control switch, make Jet pipe is connected to water inlet pipe, and water enters in jet pipe from water inlet pipe, then is sprayed from jet pipe far from handle one end, is rushed to affected part It washes.The impeller rotation being located in jet pipe is driven during water flows in jet pipe, since blade and impeller are coaxially disposed, so Blade and impeller are rotated with same rotational speed.The rotation of blade make the air in suction hose from spray head far from handle one end to close to hand The flowing of handle one end then sucks the sewage splash in oral cavity in suction hose so form negative pressure in suction hose, last sewage into Enter in sewage collection equipment.

This programme has the beneficial effect that the sewage splash is drawn onto sewage collection equipment by (one) suction hose, it is possible to It avoids sewage from splashing patient throat, and then is swallowed by patient.

(2) so that blade is formed negative pressure in suction hose come impeller rotation by the flowing of water in jet pipe, then make Suction hose sucks the water splash, so it is increased without driving device, it can structure that is energy saving, simplifying spray gun.

(3) control switch is on handle, when doctor's hand handle handle can touch control switch, so that water is sprayed or is stopped It sprays, doctor is facilitated to operate.

Preferred embodiment one, as the further improvement to base case, jet pipe is connected with tracheae, and control switch can also make Jet pipe is connected to tracheae.Jet pipe can also be connected to tracheae, so spray gun can also dry up the water in affected part, and then facilitate medical matters The treatment of personnel's progress next step.The time that medical worker replaces spray gun can be reduced, the pain of patient is reduced.

Preferred embodiment two also slidably connects control unit as the further improvement to preferred embodiment one on spray head, control Multiple elastic block pieces are fixed in portion.Control unit is slided into spray head front end, elastic block piece is stretched out from spray head far from handle one end, And then be trapped among around affected part, the sewage splash at this time can be fallen on elastic block piece, finally be slided from elastic block piece, it is possible to Sewage is avoided to splash the other positions in oral cavity completely.

Preferred embodiment three, as the further improvement to preferred embodiment two, spray head is fixed with convex block, bullet far from handle one end Property baffle be located on the outside of convex block.When elastic block piece travels forward, since convex block is crushed on the downside of elastic block piece, so convex block Elastic block piece front end can be made to tilt, the space that elastic block piece front end surrounds at this time increases, it is possible to it is biggish to be adapted to area Affected part.

Preferred embodiment four, as the further improvement to preferred embodiment three, spray head fixes finite place piece far from handle one end, Locating part is in arch door shape, and elastic block piece passes through locating part.Elastic block piece can deform after tilting, so in control unit to handle When one end is slided, packs up elastic block piece, elastic block piece still can be tilted, and elastic block piece passes through locating part, in the blocking of locating part Under, elastic block piece front end can not continue to tilt outward.

Preferred embodiment five, as the further improvement to any one of preferred embodiment one and preferred embodiment four, spray head is remote It is fixed with lighting device from handle one end, the switch that control lighting device opens and closes is additionally provided on handle.By lighting device It is arranged on spray head, lighting device can be extend into cavity interior while spray head is protruded into oral cavity, it is some to be easy by tooth The affected part that tooth blocks can also be illuminated.Secondly, the angle that adjust light only needs that spray head can be adjusted by rotating hand Angle makes illumination to different positions, and another hand can carry out other operation simultaneously.

Preferred embodiment six is fixed with sealing ring outside shaft as to which five further improvement is preferably put.Sealing ring can be with It avoids water from flowing in suction hose from jet pipe, avoids spray head leak.
