Description

Calling device for dental chair

Technical Field

The application relates to a medical instrument, in particular to a calling device for a dental chair.

Background

When a patient in the department of stomatology treats on a dental chair, the patient often has the requirements of pain intolerance, nausea or breathing disorder, and at the moment, because the oral cavity is treating or performing other operations, the patient is inconvenient to speak, and the patient usually holds up a left hand to indicate; after seeing the instruction of the patient, the doctor stops treatment or operation, inquires the specific appeal of the patient, and responds to the appeal. Many treatment processes can be relatively long, and patients can have a plurality of appeals in the whole process, so that the time spent on prompting hands and inquiring the appeals in the whole treatment process can be relatively long, and the appeals of the patients cannot be properly responded in the first time by the interactive mode.

SUMMERY OF THE UTILITY MODEL

In view of the above problems, it is an object of the present invention to provide a calling device for a dental chair, in which a patient directly reminds a medical staff with sound according to a specific appeal, and the medical staff directly deals with the appeal without an inquiry link, so that the appeal of the patient is satisfied at the first time.

The call device for a dental chair of the present application comprises: the device comprises a shell, a support column and an annular fixing ring;

the shell is internally provided with a control unit, a storage chip, a loudspeaker and three keys;

the three keys are respectively electrically connected to the control unit, and each key corresponds to one appeal; the memory chip is used for storing pre-recorded sound corresponding to each appeal; the loudspeaker is electrically connected to the control unit and used for playing the sound corresponding to each appeal;

a part of each key protrudes to the outside so as to facilitate the subject to respond to the appeal by pressing the key;

the support column is fixedly connected to the lower side of the shell;

the annular fixing ring is fixed on the lower side of the support column; the annular fixing ring is used for being sleeved on the left armrest of the dental chair.

Preferably, the housing is formed with a through hole; the through hole is used for accommodating the index finger, the middle finger, the ring finger and the little finger of the subject; the portion of each key protrudes into the through hole.

Preferably, the housing is formed with a sound propagation hole at a side facing the patient, the sound propagation hole corresponding to a position of the speaker.

Preferably, the lower side of the annular fixing ring is formed with bolt holes, and bolts are installed in the bolt holes; the head of the bolt is used for abutting against the lower side of the left armrest of the dental chair.

Through fixing the calling device who is used for the dental chair of this application on the left handrail of dental chair, the patient is during treatment, according to own appeal, presses corresponding button, and the appeal sound that should the button will be broadcast to the speaker, and medical personnel can understand patient's appeal from this, can directly deal with at the very first time.

Detailed Description

Hereinafter, the calling device for a dental chair according to the present invention will be described in detail with reference to the accompanying drawings.

The call device for a dental chair of the present application comprises: the device comprises a shell 1, a support column 2 and an annular fixing ring 3.

The housing 1 has mounted therein a control unit 10, a memory chip 20, a speaker 30, and three

keys

41, 42, 43.

The control unit 10 may be a single chip microcomputer.

The three

keys

41, 42, 43 are electrically connected to the control unit 10, respectively, each key corresponding to a respective appeal, thereby sending an appeal signal to the control unit. In particular, each key may correspond to an I/O port of the control unit 10. The memory chip 20 may be an external memory or an internal memory of the control unit 10. The memory chip 20 is used for storing pre-recorded sounds corresponding to various requirements, such as pain, nausea, and poor breathing. The speaker 30 is electrically connected to the control unit for playing the sound corresponding to each appeal, so as to intuitively reflect the appeal of the patient to the medical staff.

A portion of each

key

41, 42, 43 protrudes to the outside to facilitate the subject to react to his complaints by pressing it.

The support post 2 is fixedly attached to the underside of the housing 1.

The annular fixing ring 3 is fixed on the lower side of the support column 2; the annular fixing ring 2 is used for being sleeved on a left armrest 5 of the dental chair.

A through hole 1a is formed in the housing 1; the through hole 1a is used for accommodating the index finger, middle finger, ring finger and little finger of the subject; a part of each of the

keys

41, 42, 43 protrudes into the through hole 1 a.

When in use, a patient needs to be familiar with the corresponding appeal of each key. Specifically, the patient may be asked in advance whether or not they are susceptible to pain intolerance, nausea, poor breathing, etc., and then be asked to practice using the calling device of the present application several times before treatment. In the treatment process, if the patient is not tolerant to pain, the corresponding case, such as the key 41, is pressed, the control unit broadcasts the sound (such as the pre-recorded voice pain) corresponding to the demand stored in the storage chip through the loudspeaker after receiving the signal of the key 41, and the medical staff directly responds according to the demand after hearing the demand sound sent by the caller, so that the demand of the patient is met at the first time, and meanwhile, the inquiry time in the whole treatment process is saved.
