Abstract

The utility model discloses a thermometer comprising a thermometer body, wherein one end of the interior of the body is provided with a glass bulb which is filled with working medium; the glass bulb is connected with a hollow pipe cavity through a neck; corresponding to the hollow pipe cavity, the outer wall of the body is provided with scales; and the thermometer is characterized in that one end of the thermometer body, far away from the glass bulb, is provided with a through hole and a sling is arranged to be matched with the through hole. By arranging the through hole in one end of the thermometer body and arranging the sling to be matched with the through hole, the thermometer is led to be capable of being tied on a measurer, thus solving the problem of inconvenient use of the existing thermometers.

Description

A kind of clinical thermometer

Technical field

The utility model relates to a kind of medical diagnostic equipment, is specifically related to a kind of clinical thermometer that is used to measure human body temperature.

Background technology

In present clinical medicine, body temperature is adopted widely as an important clinical index, take temperature just must use measurement of bldy temperature instrument-clinical thermometer, claims clinical thermometer again.

The existing clinical thermometer that is used to measure human body temperature all is the elongated glass body that profile is similar to triangular generally, and there is the hollow tubular chamber inside, the corresponding hollow tubular cavity segment of outside surface has scale, the clinical thermometer front end has glass envelope, and mercury is housed in it, and glass envelope is connected by one section bent neck with hollow tube chamber.The operation material of clinical thermometer is a mercury, owing to be subjected to the influence of body temperature, produces small variation, and the expansion of mercury volume makes the length generation obvious variation of managing interior mercury slug.The variation of human body temperature is generally between 35 ℃ to 42 ℃, thus normally 35 ℃ to 42 ℃ of the scales of clinical thermometer, and also the scope of every degree is divided into 10 parts again, so clinical thermometer can be accurate to 1/10 degree.What connect glass envelope and hollow tube chamber in the clinical thermometer is a very narrow bent neck, when surveying body temperature, and the mercury in the glass envelope, the volumetric expansion of being heated, mercury can rise to certain position in the pipe by neck portion, and when reaching thermal equilibrium with body temperature, mercury slug is constant.After clinical thermometer left human body, outside air temperature was lower, and mercury is met cold volumetric contraction, just disconnect at narrow bent neck portion, the part mercury that rises up in the pipe is moved back to return, the height that still keeps mercury slug when contacting, to be reached with human body, can read body temperature numerical value this moment for the healthcare givers.Clinical thermometer is a kind of maximum thermometer, it can write down this thermometer the maximum temperature once measured, with after clinical thermometer should " return table ", promptly holding the top of clinical thermometer firmly down gets rid of suddenly, can make the mercury that has risen up in the pipe, come back in the glass envelope, prepare use next time.

Yet there is a bigger deficiency in above-mentioned clinical thermometer, be exactly clinical thermometer very inconvenience in use, must be positioned over the oral cavity of human body or be clamped in the armpit place just can accurately the display body temperature, be placed on when using in the oral cavity, in case breaking appears in clinical thermometer, the mercury of glass fragment and leakage can cause unexpected injury to the user, when being held on the armpit use, also can be because of user's carelessness, make clinical thermometer from the armpit damage of dropping, can't continue to use.

Summary of the invention

The utility model purpose provides a kind of clinical thermometer, by the improvement to structure, has solved the awkward problem of clinical thermometer in the past.

For achieving the above object, the technical solution adopted in the utility model is: a kind of clinical thermometer, comprise a clinical thermometer body, described body interior one end is provided with glass envelope, be filled with actuating medium in it, described glass envelope is connected with hollow tube chamber through a bent neck, and corresponding described hollow tube chamber is provided with scale on described body outer wall, offer through hole away from glass envelope one end on the described clinical thermometer body, cooperate with described through hole to be provided with a lanyard.

Above, described body temperature is counted and is at present generally used, and comprises a clinical thermometer body, an inner end is provided with glass envelope, be filled with mercury in it, described glass envelope is connected with hollow tube chamber through a bent neck, and corresponding described hollow tube chamber is provided with scale on described body outer wall.In the technique scheme, offer through hole away from glass envelope one end on the described clinical thermometer body, cooperate with described through hole and to be provided with a lanyard, clinical thermometer can be to hang on the neck of the measured or on the shoulder, makes the glass envelope of clinical thermometer contact (can place usually and the oxter) with human body, the mercury in the glass envelope, expanded by heating, mercury can rise to certain position in the hollow tube chamber by bent neck, and when reaching thermal equilibrium with body temperature, mercury slug is constant.After clinical thermometer left human body, outside air temperature was lower, and mercury is met cold contraction, just disconnect at bent neck portion, move back to return but risen up into hollow intraluminal part mercury, the height that still keeps mercury slug when contacting, to be reached with human body, this moment, the healthcare givers read body temperature numerical value.With after clinical thermometer should return table, prepare use next time.

Further technical scheme, described lanyard (7) is fixedlyed connected with the clinical thermometer body by knot.Described lanyard is made of a kind of of nylon wire, cotton thread or metal wire.

Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:

1, because the utility model by offer through hole away from glass envelope one end on the clinical thermometer body, cooperates with described through hole to be provided with a lanyard, makes that clinical thermometer can be to hang on the human body in use, has solved the awkward problem of clinical thermometer in the past;

2, the utility model need not existing thermometer structure is improved on a large scale, is easy to realize;

3, the utility model is simple in structure, and is easy to use, is fit to promote.

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment one.

Wherein: 1, body; 2, glass envelope; 3, bent neck; 4, hollow tube chamber; 5, scale; 6, through hole; 7, lanyard.

Embodiment

Below in conjunction with drawings and Examples the utility model is further described:

Embodiment one: referring to shown in Figure 1, a kind of clinical thermometer, comprise a clinical thermometer body 1, described body 1 an inner end is provided with glass envelope 2, be filled with actuating medium in it, described glass envelope 2 is connected with hollow tube chamber 4 through a bent neck 3, and corresponding described hollow tube chamber 4 is provided with scale 5 on described body 1 outer wall, offer through hole 6 away from glass envelope 2 one ends on the described clinical thermometer body 1, cooperate with described through hole 6 to be provided with a lanyard 7.

During use, utilize lanyard 7 that clinical thermometer system is hung on the neck or shoulder of the measured, the glass envelope 2 of clinical thermometer inserts the oxter, contact with human body, mercury expanded by heating in the glass envelope 2 rises to certain position in the hollow tube chamber 4 by bent neck 3, when reaching thermal equilibrium with body temperature, mercury slug is constant, clinical thermometer is taken away from human body, and outside air temperature is lower, and mercury shrinks, disconnect in bent neck 3 parts, but the mercury that rises up in the hollow tube chamber 4 moves back to return, the height that still keeps mercury slug when contacting, to be reached with human body, and this moment, the healthcare givers read body temperature numerical value, with after clinical thermometer should return table, prepare use next time.
