Abstract

The utility model discloses that a kind of dentistry is cold examines stimulus, comprise stimulus body and handle.Wherein, stimulus body is hollow structure, comprises top and bottom, connects between upper and lower part by screwing syndeton separately; Handle is connected with bottom.The utility model adopts medical environmental-protection plastics to make, compared to prior art, and the nontoxic and environmental protection to patient, preventing pollution infected patient.During Clinical practice, doctor only need grasp several seconds, stimulus top, screws and top can be departed from after ice in top slightly melts.The handle portion of hand-held stimulus, not contact stimulus source body, prevents ice lolly in body from accelerating to melt impact diagnosis, can meet clinician and carry out the cold requirement of examining of tooth.The utility model as Yin Wendu reason is melted repeatedly or freeze, does not all affect the result of use after being finally frozen into ice before use.Transport easy to make, clinical loss is little, is easy to clinical expansion and uses.

Description

It is a kind of that dentistry is cold examines stimulus

Technical field

The utility model relates to a kind of dental apparatus, and specifically cold the examining of a kind of dentistry uses stimulus.

Background technology

Cold examine inspection be dental disease check in requisite inspection item.It is cold when examining inspection that surgeon dentist is that the tooth of patient carries out, and requires to use " cold water instillation, ice, carbon dioxide, snow or chloroethanes are as cold stimulation source ".

In stomatologic textbook, suggestion woven hose makes little ice lolly.Compared with other several cold stimulation source, little ice lolly, because of its asepsis environment-protecting, is easy to acquisition and is more often used by clinical.But woven hose makes ice lolly and not only bothers, and woven hose both ends cannot seal, and there is pollution hidden trouble.If woven hose does not have the very first time to use after freezing taking-up, woven hose ice lolly must directly discard, can not multigelation, and loss is large.Because woven hose is comparatively thin, doctor is hand-held coldly to be examined in process ice lolly in woven hose and can affect thawing by hand temperature, need change new ice lolly and carry out cold examining, too increase clinical loss.

At present, each hospital of China there is no the apparatus of unified standard, and each medical institutions are self manufacture, both lack of standardization, can not solve the problem of sterilization, there is the hidden danger of nosocomial infection.Abroad have and HFC-134a (Endo Ice) is expelled on cotton swab as cold method of examining.But HFC-134a belongs to chemicals, not environmentally, also particular/special requirement is had to transportation and preservation.

Therefore, how solving above-mentioned the problems of the prior art is focuses that those skilled in the art study.

Summary of the invention

Technical problem to be solved in the utility model is that dentistry that propose a kind of specification, that temperature is reliable, easy to use is cold and examines stimulus.

To achieve these goals, the utility model adopts following technological means:

A kind of dentistry is cold examines stimulus, and comprise stimulus body and handle, described stimulus body is hollow structure, comprises top and bottom, connects between upper and lower part by screwing syndeton separately; Described handle is connected with described bottom.

Wherein more preferably, broken part is provided with between upper and lower part.

Wherein more preferably, upper end is provided with internal thread, and lower end is provided with external screw thread, and the two mates connection.

Wherein more preferably, stimulus body outer surface is provided with anti-skid structure.

Wherein more preferably, stimulus body is column type.

The utility model adopts medical environmental-protection plastics to make and disposablely coldly examines stimulus, compared to prior art, the nontoxic and environmental protection to patient, preventing pollution infected patient, easy to use, doctor only need grasp ice in Ji Miaodai top, stimulus top and screw and top can be departed from after slightly melting.Hand-held stimulus handle portion, not contact stimulus source body, prevents ice lolly in body from accelerating to melt impact diagnosis, can meet clinician and carry out the cold requirement of examining of tooth.Sterilization is convenient, stops nosocomial infection.Clinical unified standard uses.Before use as Yin Wendu reason is melted repeatedly or freeze, all do not affect the result of use after being finally frozen into ice.Transport easy to make, clinical loss is little, is easy to clinical expansion and uses.

Detailed description of the invention

Embodiment 1

As shown in Figures 1 and 2, a kind of dentistry is cold examines stimulus, comprises stimulus body 1 and handle 2.In the present embodiment, stimulus body is hollow cylinder shape structure.Certainly, stimulus body can be also other shapes, as cuboid, triangular form etc., can select according to clinical demand and doctor's use habit.Stimulus body 1 comprises top 11 and bottom 12, is provided with broken part 13 between top 11 and bottom 12, and broken part 13 can be a thin-walled impression, disconnects after slightly screwing top and the bottom, and also can be designed to can abscission ring structure; Handle 2 is connected with bottom 12.In the present embodiment, the outer surface portion of stimulus body is arranged with anti-skid structure, also all can be set to anti-skid structure in other embodiments.The anti-skid structure of the present embodiment is fin structure 14, also can be designed as other anti-skidding structures that can conveniently grip, as rotated screw thread or projection.The length of top 11 and bottom 12 is 1.5 ~ 3cm, and internal diameter is 0.6 ~ 0.8cm.Handle 2 is a solid rod-like structure that can grip.The cold stimulus of examining of this dentistry is preferably made up of medical plastic material.

When on ordinary days storing, cold for this dentistry stimulus of examining can be placed in refrigerator freezing indoor.During Clinical practice, taken out from refrigerator by nurse, take its outer plastic packaging film apart, be placed in patient's dental appliance box, use in order to doctor.One hand-held handle 2 when doctor uses, another hand can hold about 1 minute of the top 11 of stimulus body 1, in body, ice body screws top 11 and disconnects with bottom 12 after slightly melting, because bottom is provided with the anti-skid structure of fin, comparatively top ice body is slow for heat transfer rate, therefore bottom ice body thawing speed is slower than top ice body, and therefore whole ice body can not be separated from bottom with upper part.Remove top 11, the ice body of exposure is placed in dental surface, cold examining is carried out to tooth.The speed that ice body melts in oral cavity is about the length of 1cm per minute.

Embodiment 2

As shown in Figure 3, a kind of dentistry is cold examines stimulus, and top 11 end is provided with internal thread, and bottom 12 end is provided with external screw thread 121, and the two mates connection.Separable top and the bottom only need be screwed out during use.Other structures are with embodiment 1.The syndeton that much can screw separation in addition can be used on the utility model, does not repeat one by one at this.

Embodiment 3

As shown in Figure 4, a kind of dentistry is cold examines stimulus, is provided with and fixedly uses projective structure in bottom 12.Projective structure is nose bar 122 in the present embodiment, is located on the bottom surface in bottom 12.The effect of nose bar is mainly that fixing ice body does not rotate or comes off.Other structures are with embodiment 1.

Embodiment 4

As shown in Figure 5, a kind of dentistry is cold examines stimulus, is provided with and fixedly uses projective structure in bottom 12.Projective structure is some protruding 123 in the present embodiment, is located at lower inner wall.The effect of protruding 123 is mainly that fixing ice body does not rotate or comes off.Other structures are with embodiment 1.
