Description

Biosensors and Immobilized Structures

technical field

The utility model relates to a fixing structure, in particular to a fixing structure suitable for biosensors. the

Background technique

Fig. 1 and Fig. 2 are an existing blood oxygen concentration meter. Please refer to FIG. 1 and FIG. 2 together. An oximeter (Oximeter) 100 can be used to measure the oxygen concentration of blood. The oximeter 100 includes a fixing device like an alligator clip (Crocodile Clip). The fixing device includes base plates 111 , 112 and a spring hinge (Spring Hinge) 120 . A light sensor (Light Sensor) (not shown) is disposed on the inner side of the substrate 111 . A light source (Light Source) (not shown) is disposed inside the substrate 112 . The substrates 111, 112 include extensions 113, 114, respectively. Pressing the extensions 113 , 114 can control the distance D1 between the substrates 111 , 112 , so as to fix the finger 130 between the light sensor and the light source. Below enumerate the shortcoming of several existing blood oximeters for the reference of those skilled in the art. the

(1) Generally, the spring pivot 120 uses a metal spring. Metal springs are prone to rust, elastic fatigue and no waterproof function. Once the metal spring is damaged, the user cannot repair it by himself and has to send the oximeter 100 for repair. the

(2) The light sensor and the light source are easily disturbed by dirt, which reduces the accuracy of sensing. Users can regularly clean the light sensor and light source. However, the spring pivot 120 has a limited rotation angle, and the distance D1 is also limited. When the distance D1 is not large enough, it will seriously hinder the user from cleaning the sensor and the light source. the

(3) During the process of blood oxygen measurement by the oximeter 100 , ambient light will pass through the side openings 140 of the substrates 111 and 112 and affect the light sensor. In this way, the accuracy of the oximeter 100 will be reduced. the

(4) Once one of the extension parts 113 and 114 is damaged, the distance D1 cannot be controlled. The user cannot repair by himself, and can only send the oximeter 100 for repair. the

That is, the existing blood oxygen concentration meter has the disadvantages of being difficult to disassemble and assemble, inconvenient to clean, unable to wash with water, and users cannot repair by themselves after some parts are damaged. the

In this embodiment, the biosensor 10 is described by taking a penetrating oximeter as an example, but the present invention is not limited thereto. The biosensor 10 includes bodies 20 , 30 , a transmission line 71 and a detachable positioning device 40 . The body 20 may include a housing (not shown), a circuit C1 (as shown in FIG. 5 ) and a combination structure 61 . The body 30 includes a casing (not shown), a circuit C2 and a combination structure 62 . In this embodiment, the joint structure 61 is described by taking the protrusion on the side wall 80 as an example, and the joint structure 62 is described by taking the groove on the side wall of the body 30 as an example, but the present invention is not limited thereto. the

The transmission line 71 is electrically connected between the circuits C1 and C2 and can be used to transmit data and control signals. The detachable positioning device 40 is detachably assembled between the bodies 20 and 30, so that the joint structures 61, 62 are combined with each other and the finger 130 is fixed between the circuits C1 and C2, wherein the joint structures 61, 62 can prevent the body 20 from , 30 horizontal displacement occurs. Circuit C1 may be disposed within the housing. Circuit C2 may also be disposed within the housing. Circuit C2 may include a light emitting source, operable to emit light of different wavelengths. The circuit C1 may include a photoreceptor for sensing the light emitted by the circuit C2 and passing through the finger 130 . The circuit C1 can analyze the oxygen concentration in the blood according to the sensed light. the

In this embodiment, the body 20 further includes an extension portion 51 , a side wall 80 and two fasteners 90 . Two fasteners 90 are respectively disposed on two sides of the main body 20 for fixing two ends of the detachable positioning device 40 respectively. The firmware 90 is, for example, a screw (Screw Nail) or a rivet (Rivet). The firmware 90 is not limited to metal materials, and other materials, such as plastic materials with waterproof function, can also be used. In another embodiment, the firmware can also be integrated into the casing, for example, a hook is formed on the casing by injection molding technology, and used as the fastener. In addition, the detachable positioning device 40 can be made of elastic material, such as silicone rubber. The detachable positioning device 40 has two perforations 91 . The two through holes 91 can be buckled on the two fasteners 90 respectively. the

It is worth mentioning that silica gel has the characteristics of environmental protection, pollution-free, non-toxic, tasteless, soft texture, high elasticity, long life, anti-fouling, and easy to clean. It is a medical grade material and is an ideal material for food and medicine. The use of silicone for the detachable positioning device 40 facilitates the certification of the medical device.
