Description

Releasable test strip clamping device

Technical Field

The utility model belongs to the technical field of the test paper strip detects, concretely relates to releasable test paper strip clamping device.

Background

The portable photochemical rapid diagnosis system usually comprises a handheld detector and a corresponding test strip. The instrument is provided with an exposed light hole, the test strip reaction area is aligned with the light hole, a light-emitting element and a light-measuring element are arranged on a circuit board inside the instrument, the light-emitting element irradiates the test strip reaction area through the hole, the light-measuring element reads the color of the reaction area through the hole, then the measured color analog signal is converted into a digital signal through a photoelectric conversion principle, and finally the numerical value of the detection item is given on a display screen through operation and check. The reflected light intensity of the reaction zone of the test strip is source data obtained by an instrument, and the light intensity of the zone is closely related to the distance from the test strip to the optical element and the alignment of the reaction zone of the test strip and the light hole. Therefore, the existing instruments are all designed with test strip clamping mechanisms, and the purpose is to make the test strip tightly attached and centered to the test light hole.

However, the conventional test strip holding mechanism needs to manually pull out the test strip after the detection is finished. However, since the test strip is stained with a blood sample after use, the operator is easily contaminated by the process of manually pulling out the test strip.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1, 2, 3 and 4, a releasable strip holding device is mounted in the light-transmitting hole area of a hand-held test meter 1 and comprises a holding bracket 3, a fastener 5 and a release button 2. The outer side of the holding bracket 3 is provided with an insertion channel 302. The light hole of the hand-held detector is positioned on the insertion channel. The grip bracket 3 is provided with a socket latch 301 at a position inserted into an inner end of the channel 302. The distance between the socket latch 301 and the bottom surface of the insertion channel 302 is greater than the thickness of the strip so that the strip can protrude into the inside of the socket latch 301 along the insertion channel 302. A clamping opening is formed between the socket latch 301 and the inner end portion of the bottom surface of the insertion channel 302.

As shown in fig. 3, 4 and 5, the release button 2 is mounted on the housing of the holding bracket 3 or the hand-held measuring instrument 1, can slide, and is limited by the seam allowance, and cannot be separated from the housing of the holding bracket 3 or the hand-held measuring instrument 1. The fastener 5 includes a cantilever 501 and a stopper 502. The two ends of the cantilever 501 are respectively a fixed end and a suspended end. The cantilever 501 is made of a plastic sheet having elasticity. The bending stiffness of the cantilever 501 is greater than that of the test strip 4. The fixed end of the cantilever 501 is fixed with the holding bracket 3, and the suspended end is propped against the inner side surface of the release button 2. The cantilever 501 is obliquely disposed toward the side of the socket latch 301. In the initial state, the fixed end of the cantilever 501 is lower than the bottom surface of the insertion channel 302, and the free end is higher than the bottom surface of the insertion channel 302. When the release button 2 is pressed, the cantilever 501 is bent and deformed, so that the distance from the free end to the bottom surface of the insertion channel is reduced (until the free end returns to zero or reaches a negative value), the bending amplitude of the test strip is reduced, and the test strip falls under the action of gravity. In addition, the test strip can be released even if the free end is deformed by pressing but still higher than the bottom surface of the insertion channel. The principle is that the deformation of the cantilever weakens the clamping force, and when the clamping force is smaller than the gravity of the test strip, the test strip can naturally fall off.

The working principle of the utility model is as follows:

as shown in fig. 4, after the test strip 4 is inserted into the socket latch 301 through the insertion channel 302 on the holding bracket 3, the insertion end of the test strip 4 will touch the inclined side of the cantilever 501 on the fastener 5; because the cantilever 501 has a certain inclination relative to the test strip 4, the bending rigidity of the cantilever 501 is greater than that of the test strip 4; therefore, when the test strip 4 contacts the cantilever 501, the test strip 4 bends and continues to advance along the inclined surface of the cantilever 501 until the insertion end of the test strip 4 is blocked by the stop block 502 on the fastener 5, and the insertion of the test strip 4 is completed (at this time, the reaction area of the test strip is aligned with the transparent hole). At this time, the test strip 4 is bent and deformed, the outer side surface of the test strip 4 abuts against the edge of the socket fixture block 301 of the clamping support 3, the bent portion of the test strip 4 forms reverse elastic force on the test strip, so that the lower surface of the test strip 4 is tightly attached to the insertion channel 302 of the clamping support 3, and the friction force generated by the reverse elastic force and the attaching pressure forms clamping force on the test strip 4, so that the test strip 4 is effectively positioned, cannot be displaced, and cannot fall off.

As shown in fig. 5, after the test is completed, the instrument is kept in a vertical state, the test strip 4 faces downward, the release button 2 is pressed, so that the cantilever 501 is deformed, the inclined side surface is pressed to be flat, the test strip 4 tends to be flat, the rebound force and the attaching force are weakened, the corresponding friction force is reduced sharply, and the test strip 4 is separated from the instrument due to gravity. Therefore, the test strip which is used in a non-contact mode is discarded.

Example 2

This example differs from example 1 in that: the cantilever 501 is integrally formed with the release button 2; the release button 2 does not need to be positioned and does not need to be attached to the holding bracket 3 or the housing of the hand-held test meter 1.

Example 3

This example differs from example 1 in that: the cantilever is made of elastic materials except plastic.

Example 4

This example differs from example 1 in that: the cantilever is in the shape of an elongated strip, rather than a flat sheet.
