PHYSIOLOGICAL SIGNAL SENSING DEVICE, CONTAINING DEVICE AND METHOD FOR WEARING A PROTECTIVE FILM

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a device for properly fixing a protective film, and particularly relates to a containing device or a physiological signal sensing device with a fastening to fix a protective film.

2. Description of the Related Art

Kinds of electrical thermometer have been developed such as a pen-shaped body thermometer, a pacifier-shaped thermometer, or an IR thermometer.

Before using an ear thermometer such as IR ear thermometer, users often use a protective cap, such as a cone-shaped one, to cover a probe of the ear thermometer to provide hygienic protection. After covering a cap over the probe head, user put the probe into the ear canal of the one who are being measured to receive infrared radiation and then a signal indicating the patient's body temperature is shown. After measuring, the used protective cap will be thrown away. Then, before the next measurement, a new cap will be used to cover the probe for the next people who are being measured to prevent cross infection by directing contacting the probe.

However it is still risky to contact polluted sources by directly touching the used protective caps by hand.

Refer to FIG. 1, FIG. 1 is an ear thermometer with a protective-cap cassette in prior art. The protective-cap cassette (91) is used for containing few protective caps (910) and engaged within a handle portion (901) of a housing. The protective cap (910) comprises a solid plastic base (912) to hold a film (913) which can be extended.

However, the volume of the cassette (91) and protective caps (910) are large and they are made with more complicate procedures. Whereby this kind of ear thermometer can only contain few caps but the size is pretty large resulting in many inconveniences while using.

Please further referring to FIG. 2C first, a part of the controller (40) is disposed outside the housing (10) and another part of the controller (40) mounted into the housing (10) to connect with the sensing module (20) for providing a holding site. The controller (40) is moved along a hollow channel formed alongside the housing (10) and is extended from a side of the sensing module (20) and out of the housing (10). Whereby, users are able to move the sensing module (20) by moving the controller (40) along the channel. The controller (40) can also be designed other structure as needed, such as in another embodiment that the controller (40) can be designed as an extending part from a back end of the sensing module (20) and extended out from the back end of the housing (10) to provide a site to press.

Now referring back to FIG. 2A, the sensing module (20) is surrounded by the fastening (30). More specifically, the fastening (30) is movably engaged with the sensing module (20) by a connector. The connector in this embodiment of the present invention is a spring. In other embodiments of the present invention, it can also be connected by any selected connector as needed, such as a gear or wheel. When the sensing module (20) is moved forward to the opening (12), the fastening (30) is driven by the sensing module (20) to move toward the opening (20) so as to be able to fix an area of the protective film (72) at the opening (12).

The follower (31) is disposed at an outer site relative to the sensing module (20). More specifically, the follower (31) is disposed at one side of the fastening (30) and indirectly connects the sensing device (20) and the driving assembly (50).

Please now referring to both FIGS. 2A and 2C, the physiological signal sensing device of the embodiment in accordance with the present invention further includes an immobilizing assembly. The immobilizing assembly can be designed as a coupling assembly such as an assembly with a protrusion and a corresponding depression. In this embodiment, the immobilizing assembly is designed as two protrusions (32, 33). The protrusion (32), shown in FIG. 2A, is disposed on the sensing module (20). Another protrusion (33), shown in FIG. 2C, is disposed at an inner side of the housing (10) at the moving path that the sensing module (20) moved along.

Now referring back to FIG. 2A, the driving assembly (50) of the embodiment is a gear assembly including gears (52, 53, 54, 55 and 56). The gear (52) is able to connect with the follower (31) so as to be driven by the motion of the sensing module. The gear (54) comprises connecting gears (540, 541, and 542) and a connecting member (543). The connecting member (543) connects each axle center of connecting gears (540, 541, 542) so as to form gear (54) which can be changed in its connection situation by operation. The gear (53) is connected between the gear (52) and the connecting gear (540). By the motion forward to the opening or rearward away from the opening of the sensing module (20) can the connecting gear (541) be indirectly driven to engage with the gear (55), or selectively can the connecting gear (542) be indirectly driven to engage with the gear (56). While the connecting gear (541) is engaged with the gear (55), the connecting gear (542) is disengaged with the gear (56). In contrast, while the connecting gear (541) is disengaged with the gear (55), the connecting gear (542) engaged with the gear (56). Whereby, the driving assembly (50) is switchable to drive the transporter (60) to move.

The transporter (60) may comprise one or more transporting members for transporting the protective film (72). In this embodiment, the transporter comprises transporting members (601, 602, 603, and 604) and each of them is a columned rotatable structure. The protective film (72) can be transported by the rotation of transporting members (601, 602, 603, and 604).

The protective-film containing assembly (70) includes a containing portion (701) and an accepting portion (702). The transporting members (601, 602) respectively connect with the containing portion (701) and the accepting portion (702). The transporting members (603, 604) are respectively disposed at two sides of the opening (12). The accepting portion (702) can be rotated by the rotation of the transporting member (602). The rotation of the accepting portion (702) can drive the protective film (72) to move so as to drive the transporting members (601, 603, 604) to rotate and whereby the transporting members (601, 603, 604) transport the protective film (72) to pass across the opening (12) in a direction from the containing portion (701) toward the accepting portion (702).

To describe more specific about the operation process of the first embodiment in accordance with the present invention, please refer to both FIGS. 2A and 3A first. FIG. 3A is a schematic structure view of a portion of the physiological signal sensing device referring to FIG. 2A showing that the sensing module being moved toward a predetermined site. Please first refer to FIG. 3A, when the sensing module (20) is moved toward to the opening (12), the fastening (30) is also moved toward the opening (12) following with the sensing module (20). Then refer to FIG. 2A, after the sensing module (20) is moved till the follower (31) connects with the gear (52), the motion of the sensing module (20) drives a series action process of the gear set. First, the gear (52) rotates in counterclockwise direction so as to indirectly drive the connecting gear (540) to rotate in counterclockwise direction. The force of the rotation of the connecting gear (540) can drive the connecting member (543) to rotate in counterclockwise direction so as to have the connecting part which connects the connecting member (543) and the connecting gear (542) to move downward so as to have the connecting gear (542) connect the gear (56) and have the connecting gear (541) separated from the gear (55). By keeping rotating the gear (540) will drive the connecting gear (542) to rotate in clockwise direction so as to drive the gear (56) and the transporting member (602) to rotate in counterclockwise direction. Whereby, the transporter (60) can transports the protective film which has multiple areas includes area (721) and area (722) from the containing portion (701) to the accepting portion (702).

Then, pleas refer to FIG. 2B. FIG. 2B is a side perspective view of a partial physiological signal sensing device referring to FIG. 2A showing that the sensing module being moved toward an opening till the sensing module disconnects with the driving assembly.

After the sensing module (20) keeps being moved toward the opening (12) till the follower (31) disconnect with the gear (52) as FIG. 2B shown, the transport member (602) won't be driven by the sensing module (20) so as not to transport the protective film. As a result, the protective film stops moving. Then refer to FIG. 3B, FIG. 3B is a schematic structure view of a partial physiological signal sensing device referring to FIG. 2A showing the sensing module being moved to the predetermined site. When the sensing module (20) keeps being moved to a predetermined site (23) showed in dotted line, the fastening (30) is driven by the sensing module (20) to move to the predetermined site (23) so as to fix the area (721) at the opening (12).

Please refer to FIG. 3C, FIG. 3C is a schematic structure view of a partial physiological signal sensing device referring to FIG. 2A that the sensing module being moved over the predetermined site. When the sensing module (20) keeps being moved over the predetermined site (23) and passing through the opening (12), the area (721) is fixed and stretched over the sensing module (20) by the force from the fastening (30) and the sensing module (20). Due to the area (721) evenly covering the sensing module (20), the interference of temperature sensing from the protective film can be decreased.

Refer to FIG. 2C, after a part of the protect film (72) is stretched over the sensing module (20) (figure not shown) by moving the sensing module (20), the protrusion (32) is also moved with the motion of the sensing module (20) to couple with the protrusion (33), and therefore the sensing module can be immobilized. Therefore, user does not need to provide force to maintain the situation that the protective film covering over the sensing module. Whereby, it can increase convenience while using. When the protrusion (32) is decoupled from the protrusion (33), then it may have the sensing module (20) turn back as a movable one.

Please now refer to both FIGS. 2D and 3D. FIG. 2D is a side perspective view of the physiological signal sensing device referring to FIG. 2A showing that the sensing module is moved rearwards away from the opening to connect with the driving assembly. FIG. 3D is a schematic structure view of a partial physiological signal sensing device referring to FIG. 2A that the sensing module is moved rearwards away from the opening.

Please refer to FIG. 3D first, when the sensing module (20) is moved rearward away from the opening (as arrow shown), the fastening (30) is also moved rearward following with the motion rearward of the sensing module (20).

Refer to FIG. 2D, when the sensing module (20) is move rearwards till the follower (31) connects with the gear (52) again and then keeps being moving rearwards so as to drive the gear set with series action.

The gear (52) is driven by the motion of the follower (31) to rotate in clockwise direction. The rotation of the gear (52) indirectly drives the connecting gear (540) to rotate in the same direction. The rotation force have the connecting member (543) to rotate in clockwise so as to have the portion which connect the connecting member (543) and the connecting gear (541) to move a little bit to the left. Whereby, the connecting gear (541) can connect with the gear (55) and the connecting gear (542) disconnect with the gear (56).

While the sensing module (20) keeps being moved, the gear (55) will be driven to rotate in clockwise direction. The rotation of the gear (55) drives the gear (56) to rotate in counterclockwise direction so as to drive the transporting member (602) to rotate in counterclockwise direction. Whereby, the transporter (60) transports the protective film (72) from the containing portion (701) to the accepting portion (702).

By means of the acting process described above referring to FIG. 2D, the area (722) referring in FIG. 3D is transported to the moving path which the sensing module (20) is moved toward the opening (12) and replace the area (721). The area (721) then is transported toward the accepting portion (702). By means of the driving assembly (50), whether the sensing module (20) is moved forward or backward or not, the protective film (72) can be transported. Hence, by the time the used area of protective film (72) is transported away from the opening (12), a new one is transported to the opening (12) in order to not only avoid using the used area by user but also efficiently use the moving distance of the sensing module (20) to move an area of an unused protective film to the opening (12).

In addition, please refer to FIGS. 3A to 3D and 4. FIG. 4 is a flow chart of a method for wearing a protective film of a physiological signal sensing device in accordance with the present invention.

The method of the embodiment in accordance with the present invention includes:

transporting an area (721) of the protective film (72) to a site of a moving path that a sensing module (20) moves toward an opening (12) by a transporter (S10);

moving the sensing module (20) through the opening (12) for stretching the area (721) over the sensing module (20) (S12).

By the steps (S10 to S12), a method for wearing a protective film over a sensing module (20) is accomplished.

Then the next steps are for next wearing process. The next steps include:

transporting an area (722) to the position of the area (721) located to replace the area (721) by a transporter (S20);

fixing the area (722) at the opening (12) by the fastening (S21);

moving the sensing module (20) through the opening (12) for stretching the area (722) over the sensing module (20). By repeat the steps described above, the process of wearing an area of a protective film can continue.
