Abstract

A thermometer quick linkage apparatus comprises an elastic member, a button, a probe, and a chamber having one end provided with an opening for receiving the end portion of the probe, and the other end also provided with an opening for receiving the button. Within the chamber, one end of the elastic member connects with the button, and the other end thereof connects with the probe. The elastic member is configured such that, when the button is pressed to compress the elastic member to a certain degree, the end portion of the button comes into contact with the end portion of the probe, and when the button is pressed further down, the probe is pushed away from the chamber. The apparatus is simplified in structure, and allows quick replacement of the probe jacket, and therefore is cost-efficient.

Claims

1. A thermometer quick linkage apparatus comprising:

an elastic member;

a button that defines an end portion;

a probe configured to communicate with a host of the thermometer via a leading wire, the probe defining an end portion; and

a chamber defining a neck portion at a first end thereof that is dimensioned to have a probe jacket inserted thereon and to mate snugly with the probe jacket, wherein the neck portion defines an opening through which the probe is received, the chamber having a second end provided with an opening through which the button is received;

wherein, within the chamber, a first end of the elastic member is connected with the button and a second end of the elastic member is connected with the probe;

wherein the probe fits loosely in the opening at the first end of the chamber that is defined by the neck portion of the chamber, and wherein the probe is spaced from and unconstrained by all remaining portions of the chamber; and

wherein the elastic member is configured such that, when the button is pressed to compress the elastic member to a certain degree, the end portion of the button comes into contact with the end portion of the probe, and wherein, when the button is pressed further, the button pushes the probe away from the second end of the chamber such that the only contact between the probe and the chamber and the only constraint of the probe by the chamber occurs at the opening at the first end of the chamber as the probe is pushed.

2. The thermometer quick linkage apparatus of claim 1, wherein the elastic member comprises a helical spring, one end of which is connected with the button, and the other end of which is inserted onto the end portion of the probe.

3. The thermometer quick linkage apparatus of claim 1, wherein a stop member is provided on a portion of the button that is located within the chamber to prevent the button from disengaging from the chamber;

and wherein a stop member is also provided on a portion of the probe that is located within the chamber to prevent the probe from disengaging from the chamber.

4. The thermometer quick linkage apparatus of claim 1, wherein at least a portion of the chamber is cylindrical and wherein an inner diameter of the neck portion of the chamber is smaller than an inner diameter of the cylindrical portion of the chamber.

5. The thermometer quick linkage apparatus of claim 1, wherein the chamber takes a shape of one of a circular cylinder, an elliptical cylinder, and a prism.

6. The thermometer quick linkage apparatus of claim 1, wherein the button, the elastic member, and the probe are arranged to be substantially coaxial.

7. The thermometer quick linkage apparatus of claim 1, wherein the elastic member encompasses the end portion of the probe.

8. The thermometer quick linkage apparatus of claim 1, wherein at any stage during depression of the button, the only contact between the probe and the chamber remains at the neck portion of the chamber.

9. The thermometer quick linkage apparatus of claim 1, wherein only the elastic member is arranged between the button and the probe.

10. A thermometer quick linkage apparatus, comprising:

an elastic member;

a button, one end of which is provided with a supporting seat that protrudes from the button;

a probe configured to communicate with a host of the thermometer via a leading wire; and

a chamber defining a neck portion at an end thereof that is dimensioned to have a probe jacket inserted thereon and to mate snugly with the probe jacket, wherein the neck portion defines an opening for receiving an end portion of the probe, the chamber further having a side that defines an axially extending slotted hole through which the button is received such that the button is configured to translate within the slotted hole;

wherein, within the chamber, one end of the elastic member is connected with the supporting seat and another end of the elastic member is connected with the probe;

wherein the probe fits loosely in the opening at the end of the chamber that is defined by the neck portion of the chamber, and wherein the probe is spaced from and unconstrained by all remaining portions of the chamber; and

wherein the elastic member is configured such that, when the button is pushed along the slotted hole so as to compress the elastic member to a certain degree, the supporting seat comes in contact with the end portion of the probe, and wherein, when the button is pushed further, a portion of the probe is pushed through the opening of the chamber, wherein the only contact between the probe and the chamber and the only constraint of the probe by the chamber occurs at the opening of the chamber as the portion of the probe is pushed.

11. The thermometer quick linkage apparatus of claim 10, wherein the elastic member comprises a helical spring, one end of which is connected with the supporting seat, and the other end of which is inserted onto the end portion of the probe.

12. The thermometer quick linkage apparatus of claim 10, wherein a stop member is provided on a portion of the probe that is located within the chamber to prevent the probe from disengaging from the chamber.

13. The thermometer quick linkage apparatus of claim 10, wherein at least a portion of the chamber is cylindrical and wherein an inner diameter of the neck portion of the chamber is smaller than an inner diameter of the cylindrical portion of the chamber.

14. The thermometer quick linkage apparatus of claim 10, wherein the elastic member and the probe are arranged to be substantially coaxial.

15. The thermometer quick linkage apparatus of claim 10, wherein the elastic member encompasses the end portion of the probe.

16. The thermometer quick linkage apparatus of claim 10, wherein at any stage during depression of the button, the only contact between the probe and the chamber remains at the neck portion of the chamber.

17. The thermometer quick linkage apparatus of claim 10, wherein only the elastic member is arranged between the button and the probe.

18. A method for ejecting a probe jacket from a thermometer, the method comprising:

providing a thermometer that comprises a chamber having a neck portion that is dimensioned to receive a probe jacket thereon, a button, a probe that extends through the neck portion of the chamber, an elastic member connected with both the button and the probe, and a probe jacket that covers the probe and is connected to the neck portion of the chamber;

compressing the elastic member by moving the button;

contacting the probe with the button after the elastic member has been compressed;

pressing the button further while the button contacts the probe so as to move the probe through the neck portion of the opening without the probe contacting or being constrained by any other portion of the chamber and so as to force the probe jacket off of the neck portion of the chamber.

19. The method of claim 18, wherein the elastic member is configured such that when the elastic member is compressed by pressing the button, the probe remains substantially still.
