Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a blood oxygen detection finger sleeve structure. Background Art

[0002] Blood oxygen saturation (SaO2) is the percentage of the volume of oxygenated hemoglobin (HbO2) bound to oxygen in the blood accounting for the volume of all bindable hemoglobin (Hb, hemoglobin), that is, the concentration of blood oxygen in the blood. Blood oxygen saturation is an important physiological parameter of the respiratory cycle and an important indicator for evaluating human respiratory health. During the measurement of blood oxygen saturation, generally, a detection finger sleeve is put on a person's finger, and the finger is regarded as a transparent container for containing hemoglobin. Red light with a wavelength of 660 nm and near-infrared light with a wavelength of 940 nm are used as the incident light sources to measure the light conduction intensity passing through the tissue bed, so as to calculate and display the hemoglobin concentration and blood oxygen saturation, thereby realizing continuous non-invasive measurement of blood oxygen. However, in traditional blood oxygen finger sleeves, the light-emitting diodes and receiving tubes are mostly exposed inside the finger sleeve. After the subject inserts the finger into the finger sleeve, it is easy to rub the light-emitting diodes and receiving tubes, causing the light-emitting diodes and receiving tubes to shift or even be damaged, thereby affecting the effective collection of human blood oxygen data. In addition, the connection parts of the connecting wire of the traditional blood oxygen finger sleeve with the receiving tube and the light-emitting diode are mostly in a suspended state, lacking positioning of the connection parts, and the connection stability is insufficient. When the connecting wire is subjected to a large instantaneous external force, the connection part is easily disconnected, thereby causing the blood oxygen finger sleeve to be unable to normally collect human blood oxygen parameters and affecting the effective collection of human blood oxygen data.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] In order to make the above-mentioned objects, features, and advantages of the present utility model more obvious and understandable, the following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0027] Please refer to Figures 1-6 , the present utility model discloses a blood oxygen detection finger sleeve structure in which a receiving tube and a light emitting tube are hermetically packaged, are not easily displaced, and have high stability at the wiring part to ensure the effective progress of blood oxygen collection operation. The blood oxygen detection finger sleeve structure includes a finger sleeve body 100, a light emitting component 200, a receiving component 300, a connector 400, and a cable assembly 500. A detection cavity 110 for inserting a finger is provided inside the finger sleeve body 100. An insertion port 120 communicating with the detection cavity 110 is provided at one end of the finger sleeve body 100, and a fingertip outlet 130 communicating with the detection cavity 110 is provided at the other end of the finger sleeve body 100. That is to say, the finger sleeve body 100 is integrally in a tubular structure so that the subject can insert a finger into the finger sleeve body 100 for detection. A first installation groove 140 located above the detection cavity 110 and communicating with the detection cavity 110, a second installation groove 150 located below the detection cavity 110 and communicating with the detection cavity 110 and corresponding to the first installation groove 140, a limiting groove 160 located below the detection cavity 110 and communicating with the second installation groove 150, and a connection groove 170 located beside the detection cavity 110 and communicating the first installation groove 140 and the second installation groove 150 are further provided inside the finger sleeve body 100. Preferably, the outer surface of the finger sleeve body 100 protrudes to form the first installation groove 140 communicating with the detection cavity 110 inside the finger sleeve body 100. In this embodiment, after the subject's finger is inserted into the detection cavity 110, the first installation groove 140 is adjacent to the back of the subject's finger, and the second installation groove 150 is adjacent to the palm of the subject's finger; similarly, the limiting groove 160 is located below the palm of the subject's finger, and the connection groove 170 is located beside the finger and semi-surrounds the finger to realize the communication between the first installation groove 140 and the second installation groove 150.

[0028] A partition part 180 is provided between the limit groove 160 and the detection cavity 110, and the limit groove 160 penetrates through the end surface of the finger sleeve body 100 where the insertion port 120 is located. It can also be understood that the finger sleeve body 100 has a cavity that penetrates through its two opposite end surfaces. A partition part 180 extending from one end of the finger sleeve body 100 to the other end is provided in this cavity. One end of the partition part 180 located in the cavity is fixed to the inner surface of the finger sleeve body 100. In this way, the cavity of the finger sleeve body 100 is divided into a detection cavity 110 and a limit groove 160 located below the detection cavity 110 by the partition part 180. Among them, the detection cavity 110 serves as a passage for the finger to pass through, and the limit groove 160 serves as a passage for the cable assembly 500 to pass through. The cable assembly 500 is independently arranged to avoid contact with the cable during the detection process of the subject.

[0029] The light-emitting component 200 includes a light-emitting tube 210 received in the first installation groove 140 and a first flexible transparent protective layer 220 covering the outer surface of the light-emitting tube 210. The outer surface of the first flexible transparent protective layer 220 is fixedly connected to the inner surface of the first installation groove 140. The receiving component 300 includes a receiving tube 310 received in the second installation groove 150 and a second flexible transparent protective layer 320 covering the outer surface of the receiving tube 310. The outer surface of the second flexible transparent protective layer 320 is fixedly connected to the inner surface of the second installation groove 150. In this embodiment, the first flexible transparent protective layer 220 is used to encapsulate the light-emitting tube 210, and at the same time, the positioning of the light-emitting tube 210 is realized by the fitting of the first flexible transparent protective layer 220 and the inner surface of the first installation groove 140; the second flexible transparent protective layer 320 is used to encapsulate the receiving tube 310, and at the same time, the positioning of the receiving tube 310 is realized by the fitting of the second flexible transparent protective layer 320 and the inner surface of the second installation groove 150. The light-emitting tube 210 and the receiving tube 310 cooperate together to realize the detection of the blood oxygen of the subject. Specifically, the light-emitting tube 210 emits detection light of a specific wavelength under the control of an external blood oxygen meter. The detection light passes through the finger of the subject and is received by the receiving tube 310. The receiving tube 310 further sends the detected signal to the external blood oxygen meter, and the blood oxygen meter calculates the blood oxygen saturation according to the change of the light conduction intensity, so as to complete the detection of the blood oxygen of the subject.

[0030] The connector 400 is located outside the finger sleeve body 100 and is used for electrically connecting with an external blood oxygen meter. The flexible cable assembly 500 includes a cable tube 510, a first flexible cable 520 that passes through the cable tube 510 and the limiting groove 160 and is inserted into the connection groove 170 to be electrically connected to the light emitting tube 210 and the connector 400, and a second flexible cable 530 that passes through the cable tube 510 and the limiting groove 160 and is electrically connected to the receiving tube 310 and the connector 400 respectively. One end of the cable tube 510 is inserted into the limiting groove 160, and the outer surface of the cable tube 510 is fixedly connected to the inner surface of the limiting groove 160. The other end of the cable tube 510 extends out of the limiting groove 160. That is to say, the cable tube 510 is partially inserted into the limiting groove 160 to realize the positioning of the cable tube 510.

[0031] The finger sleeve body 100 is used to insert the finger of the subject to be collected for blood oxygen to provide a place for blood oxygen detection. In one embodiment, a detection positioning portion 101 is formed by a protrusion at the edge of the notch of the second installation groove 150 in the detection cavity 110. Further preferably, after the first flexible transparent protective layer 220 wraps the light emitting tube 210, the surface of the first flexible transparent protective layer 220 adjacent to the detection cavity 110 is flush with the inner side surface of the detection cavity 110; after the second flexible transparent protective layer 320 wraps the receiving tube 310, the surface of the second flexible transparent protective layer 320 adjacent to the detection cavity 110 is flush with or lower than the detection positioning portion 101. Thus, during the blood oxygen detection process, when the subject inserts the finger into the detection cavity 110, the subject can judge whether the placement position of the finger is in place according to whether the finger contacts the detection positioning portion 101, so as to facilitate the smooth progress of the blood oxygen detection operation and ensure the reliability of the blood oxygen detection result. The first flexible transparent protective layer 220 and the second flexible transparent protective layer 320 are made of a transparent flexible material. For example, the first flexible transparent protective layer 220 and the second flexible transparent protective layer 320 are made of TPU material. Of course, the first flexible transparent protective layer 220 can also be formed on the surface of the light emitting tube 210 by placing the light emitting tube 210 in a mold filled with transparent glue and waiting for the glue to dry; the second flexible transparent protective layer 320 can be formed on the surface of the receiving tube 310 by placing the receiving tube 310 in a mold filled with transparent glue and waiting for the glue to dry.

[0032] The connector 400 serves as the electrical connection part between the blood oxygen detection finger sleeve structure and the external blood oxygen meter. In this embodiment, the connector 400 can be located on the side of the finger sleeve body 100 where the insertion port 120 is located, or on the side of the finger sleeve body 100 where the fingertip outlet 130 is located. Further, the connector 400 is provided with a first connection port electrically connected to the first cable 520 and a second connection port electrically connected to the second cable 530. According to the different numbers of the first cable 520 and the second cable 530, there can be multiple first connection ports and multiple second connection ports on the connector 400. The number of the first connection ports is the same as the number of the first cable 520, and the number of the second connection ports is the same as the number of the second cable 530. Pins are provided at the ends of both the first cable 520 and the second cable 530. Through the insertion of the pins at the first connection port and the second connection port, the electrical connection between the first cable 520 and the second cable 530 and the connector 400 is achieved.

[0033] In one embodiment, the inner surface of the cable sheath 510 is in close contact with the outer surfaces of the first cable 520 and the second cable 530 and bundles the first cable 520 and the second cable 530 to prevent the first cable 520 and the second cable 530 from shaking within the cable sheath 510. To improve the stability of the cable sheath 510 in limiting the first cable 520 and the second cable 530, the inner surface of the cable sheath 510 is also bonded to the first cable 520 and the second cable 530 to prevent the connection part of the first cable 520 from disconnecting from the light emitting diode 210 under external pulling force, and at the same time prevent the connection part of the second cable 530 from disconnecting from the receiving tube 310 under external pulling force. In one embodiment, the cable sheath 510 includes a cylindrical tube body 511, a first positioning tube 512 fixed at one end of the cylindrical tube body 511 and communicating with the inner cavity of the cylindrical tube body 511, and a second positioning tube 513 fixed at the other end of the cylindrical tube body 511 and communicating with the inner cavity of the cylindrical tube body 511. The outer diameters of the first positioning tube 512 and the second positioning tube 513 are respectively larger than the outer diameter of the cylindrical tube body 511. The first positioning tube 512 is located in the limiting groove 160 and fixedly connected to the inner surface of the limiting groove 160, and a part of the cylindrical tube body 511 is inserted into the limiting groove 160. Preferably, the cylindrical tube body 511, the first positioning tube 512 and the second positioning tube 513 are integrally formed.

[0034] It should be noted that in this embodiment, the finger sleeve body 100 is made of an elastic material. For example, the finger sleeve body 100 is made of a silicone material or a rubber material to reduce scratches on the fingers of the subject. At the same time, when the finger of the subject is inserted into the finger sleeve body 100, the inner surface of the finger sleeve body 100 can fit with the back and the belly of the finger to improve the detection effect and the reliability of the detection result. Further, the hardness of the wire bundle tube 510 is greater than that of the finger sleeve body 100, and the outer diameters of the first positioning tube 512 and the second positioning tube 513 are both greater than the inner diameter of the limiting groove 160. In this embodiment, by providing the first positioning tube 512 and the second positioning tube 513 with outer diameters both greater than the inner diameter of the limiting groove 160, when the first positioning tube 512 is inserted into the limiting groove 160, the inner surface of the limiting groove 160 is squeezed and deformed, and wraps and presses the edge of the first positioning tube 512 to realize the limitation of the first positioning tube 512 and prevent the first positioning tube 512 from falling off the limiting groove 160 by itself, thus improving the positioning stability of the first wire arrangement 520 and the second wire arrangement 530. The second positioning tube 513 is located outside the limiting groove 160 and its outer diameter is greater than the inner diameter of the limiting groove 160, which can prevent the whole wire bundle tube 510 from being stuffed into the limiting groove 160, providing a gripping part for the operator. So that when assembling and disassembling the blood oxygen detection finger sleeve structure, the operator can grip the second positioning tube 513 and take the wire bundle tube 510, the first wire arrangement 520 and the second wire arrangement 530 away from the finger sleeve body 100, or push the second positioning tube 513 to insert the first positioning tube 512 into the limiting groove 160 to realize the positioning of the wire bundle tube 510. Preferably, the insertion depth of the cylindrical tube body 511 in the limiting groove 160 and the length of the cylindrical tube body 511 are in a ratio between 0.5 and 1, which can ensure a large cooperation area between the wire bundle tube 510 and the limiting groove 160, improve the installation stability of the wire bundle tube 510, and facilitate the operator to grip the second positioning tube 513.

[0035] In one embodiment, on the outer surface of the finger sleeve body 100 on the side where the second installation groove 150 is located, there are connection protrusions 102 and a mounting plate 103 fixed on the connection protrusions 102. A plurality of mounting holes 104 are provided on the mounting plate 103. By providing the connection protrusions 102 and the mounting plate 103 on the outside of the finger sleeve body 100, a preset distance is provided between the mounting plate 103 and the outer surface of the finger sleeve body 100. In this way, when the blood oxygen detection finger sleeve structure is idle, the mounting plate 103 can be hung on an external hook, or the blood oxygen detection finger sleeve structure can be hung on an external hook through the mounting holes 104 on the mounting plate 103, so as to avoid damage caused by the blood oxygen detection finger sleeve structure being accidentally stepped on or touched after falling to the ground.

[0036] The above-mentioned blood oxygen detection finger sleeve structure wraps the light-emitting tube 210 with the first flexible transparent protective layer 220 and fixes the light-emitting tube 210 in the first installation groove 140, and wraps the receiving tube 310 with the second flexible transparent protective layer 320 and fixes the receiving tube 310 in the second installation groove 150. While ensuring effective optical signal transmission between the light-emitting tube 210 and the receiving tube 310, it realizes the encapsulation protection and positioning of the light-emitting tube 210 and the receiving tube 310, and can avoid the problems of displacement and damage of the detection components caused by the direct contact between the fingers of the subject and the light-emitting tube 210 and the receiving tube 310, so as to extend the service life of the blood oxygen detection finger sleeve structure and ensure the normal use of the blood oxygen detection finger sleeve structure; by setting a limiting groove 160 below the detection cavity 110 and fixing the wire bundle tube 510 at the notch of the limiting groove 160, the first wiring line 520 and the second wiring line 530 are bundled and fixed, and the problem that the connection part of the first wiring line 520 and the light-emitting tube 210 and the connection part of the second wiring line 530 and the receiving tube 310 are disconnected due to external pulling can be prevented, the stability of the wiring part is improved, and the effective connection between the light-emitting tube 210 and the receiving tube 310 and the external blood oxygen meter and the normal use of the blood oxygen detection finger sleeve structure are ensured.

[0037] The technical features of the above-mentioned embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0038] The above-mentioned embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
