Abstract

The utility model relates to a thermometer for measuring the human body temperature, specifically to a breakage-proof thermometer which is provided with glass tube body with a capillary inside; the low end of the glass tube body has a temperature sensing head; the glass tube body is sleeved with a protective sleeve; an elongated observation hole is arranged on the side wall of the protective sleeve; the observation hole is in parallel to an axis of the glass tube body; and an openable end cap is disposed on the lower end of the protective sleeve. The breakage-proof thermometer is externally provided with the protective sleeve which buffers for impact and prevents the thermometer from being broken; additionally, even though the thermometer is broken, the protective sleeve could collect the cullet and the liquid mercury, thus preventing the cullet from damaging people and avoiding environment pollution after leak of the liquid mercury.

Description

Breakage-proof clinical thermometer

Technical field

The utility model relates to a kind of clinical thermometer of material human body temperature, is a kind of breakage-proof clinical thermometer specifically.

Background technology

In order to obtain result of use preferably, the main body of clinical thermometer all is made of glass usually.But this has also brought simultaneously some drawbacks: Glass breadks easily, clinical thermometer are collided after fracture or the fragmentation, and cullet are hurted sb.'s feelings easily, and the mercury that the clinical thermometer fragmentation is run off later on also causes environmental pollution easily.

Summary of the invention

The purpose of this utility model provide a kind of simple in structure, easy to use, can effectively prevent to be collided fragmentation, prevent the breakage-proof clinical thermometer that cullet are hurted sb.'s feelings also have the effect that prevents that mercury runs off simultaneously.

For achieving the above object, the utility model is by the following technical solutions:

Breakage-proof clinical thermometer described in the utility model; comprise that inside is provided with canals of stilling capillaceous; the lower end of described canals of stilling has temperature-sensitive head; it is characterized in that: canals of stilling is set with protective sleeve outward; the sidewall of described protective sleeve is provided with the viewport of strip; the parallel axes of described viewport and canals of stilling, the lower end of protective sleeve is provided with openable end cap.

After adopting technique scheme, this breakage-proof clinical thermometer is protective sleeve in addition, can cushion the collision that is subjected to, and it is broken to avoid clinical thermometer to be subjected to bump.In addition, even after the clinical thermometer fragmentation, protective sleeve also can play the effect of collecting cullet and liquid mercury, and loss causes later environmental pollution with liquid mercury to avoid cullet to hurt sb.'s feelings.

Description of drawings

Fig. 1 is the structural representation of an embodiment of the utility model;

Fig. 2 is the right view of Fig. 1 embodiment.

Embodiment

The utility model will be further described below in conjunction with the drawings and specific embodiments.

As shown in Figure 1 and Figure 2, breakage-proof clinical thermometer described in the utility model comprises that inside is provided with canals of stilling 1 capillaceous, have scale on the sidewall of described canals of stilling 1, the lower end of canals of stilling 1 has temperature-sensitive head 2, thermally sensitive liquid such as liquid mercury are housed, in the temperature-sensitive head in the time of the temperature inversion of temperature-sensitive head 2, because the principle of expanding with heat and contract with cold, the length of the liquid mercury column in the capillary can change, and determines temperature value with this.The canals of stilling 1 outer protective sleeve 3 that is set with; the material of softnesses such as described protective sleeve 3 employing silica gel is made; the sidewall of protective sleeve 3 is provided with the viewport 4 of strip; the parallel axes of described viewport 4 and canals of stilling 1; the position of viewport 4 is corresponding with the scale on the canals of stilling 1, so that read scale value when using.The lower end of protective sleeve 3 is provided with openable end cap 5, end cap 5 adopts and protective sleeve 3 identical materials, position with its about 1/3 circumference links to each other with protective sleeve 3, can at an easy rate protective sleeve 3 be enclosed within on the temperature-sensitive head 2 when depositing like this, plays a protective role; Can easily protective sleeve 3 be taken off again when in use and be folded to one side, temperature-sensitive head 2 is exposed, allow temperature-sensitive head 2 contact, reach the purpose of accurate take temperature with human body.

Claims

1. breakage-proof clinical thermometer; comprise that inside is provided with canals of stilling capillaceous (1); the lower end of described canals of stilling (1) has temperature-sensitive head (2); it is characterized in that: the outer protective sleeve (3) that is set with of canals of stilling (1); the sidewall of described protective sleeve (3) is provided with the viewport (4) of strip; the parallel axes of described viewport (4) and canals of stilling (1), the lower end of protective sleeve (3) is provided with openable end cap (5).
