Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of medical devices, and in particular relates to an ear-hanging type pulse oxygen saturation monitoring probe. Background Art
[0002] Currently, when monitoring the blood oxygen saturation of patients in clinical practice, fingertip pulse oxygen saturation monitoring probes are often used to clamp the patient's fingers or toes for monitoring. If the patient's limbs are injured or require surgery, an ear pulse oxygen saturation monitoring probe is needed to clamp the patient's earlobe for monitoring. If the ear pulse oxygen monitoring probe is used for too long, ischemia of the earlobe distal end is prone to occur, which reduces the monitoring sensitivity. Utility Model Content
[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an ear-hanging ear pulse oxygen saturation monitoring probe. When the monitoring probe of the utility model detects the blood oxygen saturation at the earlobe, it can ensure the wearing stability of the probe and avoid clamping too tightly to cause earlobe ischemia.
[0004] The purpose of this disclosure can be achieved through the following technical solutions:
[0005] An ear-hanging pulse oxygen saturation monitoring probe, comprising:
[0006] A plastic semi-arc circular tube, wherein a first soft plastic circular tube and a second soft plastic circular tube are respectively arranged at both ends of the plastic semi-arc circular tube, a first metal gooseneck is arranged inside the first soft plastic circular tube, the first metal gooseneck is fixedly connected to the upper end of the first soft plastic circular tube and the plastic semi-arc circular tube, and an earplug fixing head is fixedly connected to the lower end, a second metal gooseneck is arranged inside the second soft plastic circular tube, the second metal gooseneck is fixedly connected to the upper end of the second soft plastic circular tube and the plastic semi-arc circular tube, and a monitoring block is fixedly connected to the lower end, a notch is opened on the monitoring block, plastic cards are fixedly connected on both sides of the notch, and a monitoring component is embedded in the plastic card.
[0007] The above technical solution, its principle and technical effect:
[0008] Hang the plastic semi-arc tube on the patient's ear neck, bend the first metal gooseneck tube and the second metal gooseneck tube at an angle to fit the patient's ear contour, insert the earplug fixing head into the patient's ear hole to further enhance the firmness, align the notch on the monitoring block with the patient's earlobe, insert the patient's earlobe between the two plastic cards in the notch, and the monitoring component monitors the blood oxygen saturation of the patient's earlobe. On the one hand, the ear-hanging method increases the firmness of the device, and the patient can perform long-term earlobe clamping monitoring. On the other hand, the notch restriction method avoids the traditional clamping method, which causes earlobe ischemia due to excessive clamping and affects the monitoring results.

[0017] The nouns, conjunctions or adjectives involved in the above technical solution are explained as follows:
[0018] Fixed connection refers to a connection in which parts or components are fixed without any relative movement. There are two types of connection: detachable and non-detachable.
[0019] (1) Removable connections use screws, splines, wedge pins, etc. to fasten parts together. This type of connection can be disassembled for maintenance without damaging the parts. However, the specifications of the connectors used must be correct (such as the length of the bolts, keys, and wedge pins) and they must be properly tightened.
[0020] (2) Non-detachable connections mainly refer to welding, riveting and tenoning. Since they need to be disassembled by forging, sawing or oxygen cutting during maintenance or replacement, spare parts generally cannot be reused. At the same time, when making connections, attention should be paid to process quality, technical inspection and remedial measures (such as calibration, polishing, etc.).
[0021] A threaded connection refers to a detachable connection in which the connected parts are connected together using threaded parts (or the threaded part of the connected parts).
[0022] A sliding connection is when two objects are in contact but not fixed and can slide relative to each other.
[0023] A rotational connection is a connection between parts that allows the parts to rotate relative to each other.
[0024] Beneficial effects of the present disclosure:
[0025] The monitoring probe of the utility model can ensure the stability of the probe when detecting the blood oxygen saturation at the earlobe, and can also avoid clamping too tightly to cause earlobe ischemia. At the same time, both ears can be used, and when one ear reaches a certain monitoring time, the other earlobe can be monitored. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0031] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.
[0032] In the description of the present disclosure, it should be understood that terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limitations on the present disclosure.
[0033] According to the concept of this application, Figure 1-3 To describe an embodiment of an ear-hanging ear pulse oxygen saturation monitoring probe. Specifically, the ear-hanging ear pulse oxygen saturation monitoring probe is constructed as a split structure, which has a plastic semi-arc circular tube 5, an earplug fixing head 1, a monitoring block 15 and other structures that cooperate with each other. The plastic semi-arc circular tube 5 is hung on the patient's ear neck, and the first metal gooseneck tube 3 and the second metal gooseneck tube 8 are bent at an angle to adapt to the patient's ear contour shape. The earplug fixing head 1 is inserted into the ear hole of the patient's ear to further improve the firmness, and then the notch on the monitoring block 15 is aligned with the patient's earlobe, and the patient's earlobe is inserted between the two plastic cards 10 in the notch. The monitoring component monitors the blood oxygen saturation of the patient's earlobe. On the one hand, the firmness of the device is increased by hanging the ear, and the patient can perform long-term earlobe clamping monitoring. On the other hand, the notch restriction method can avoid the traditional clamping method, which causes earlobe ischemia due to excessive clamping and affects the monitoring results.
[0034] like Figure 1-3 As shown, an ear-hanging type pulse oxygen saturation monitoring probe comprises:
[0035] A plastic semi-arc circular tube 5, with a first soft plastic circular tube 4 and a second soft plastic circular tube 7 respectively arranged at both ends of the plastic semi-arc circular tube 5, a first metal gooseneck 3 is arranged inside the first soft plastic circular tube 4, the upper ends of the first metal gooseneck 3 and the first soft plastic circular tube 4 are fixedly connected to the plastic semi-arc circular tube 5, and the lower ends are fixedly connected to an earplug fixing head 1, a second metal gooseneck 8 is arranged inside the second soft plastic circular tube 7, the upper ends of the second metal gooseneck 8 and the second soft plastic circular tube 7 are fixedly connected to the plastic semi-arc circular tube 5, and the lower ends are fixedly connected to a monitoring block 15, a notch is opened on the monitoring block 15, and plastic cards 10 are fixedly connected on both sides of the notch, and a monitoring component is embedded in the plastic card 10.
[0036] When in use, the plastic semi-arc circular tube 5 is hung on the patient's ear neck, the first metal gooseneck tube 3 and the second metal gooseneck tube 8 are bent at an angle to adapt to the patient's ear contour shape, and the earplug fixing head 1 is inserted into the ear hole of the patient's ear to further improve the firmness, and then the notch on the monitoring block 15 is aligned with the patient's earlobe, and the patient's earlobe is inserted between the two plastic cards 10 in the notch. The monitoring component monitors the blood oxygen saturation of the patient's earlobe. On the one hand, the firmness of the device is increased by hanging the ear, and the patient can perform long-term earlobe clamping monitoring. On the other hand, the notch restriction method can avoid the traditional clamping method, which causes earlobe ischemia due to excessive clamping and affects the monitoring results.
[0037] In one embodiment of the present invention, the inner side of the earplug fixing head 1 is detachably connected with a rubber earplug 2, so as to protect the soft tissue of the ear hole.
[0038] In one embodiment of the present invention, the monitoring assembly includes a light emitting diode and an infrared sensor respectively embedded in two plastic cards 10 .
[0039] Blood oxygen saturation monitoring calculates blood oxygen saturation by measuring changes in the absorption of light of a specific wavelength by human tissue. Its basic working principle is to use the difference in the absorption characteristics of oxygenated hemoglobin (HbO2) and reduced hemoglobin (Hb) to red light and infrared light. Oxygenated hemoglobin (HbO2) absorbs more infrared light and allows more red light to pass through, while reduced hemoglobin (Hb) absorbs more red light and allows more infrared light to pass through.
[0040] A light-emitting diode is used to emit red light of about 660nm and infrared light of about 915nm. The light passes through the skin of the measured part (such as the fingertip or earlobe), and then is received by the infrared sensor, which converts the light signal into an electrical signal for output. Since oxygenated hemoglobin and reduced hemoglobin absorb light of these two wavelengths differently, by detecting the difference in absorption of these two lights, the relative proportion of oxygenated hemoglobin and reduced hemoglobin can be calculated, and then the blood oxygen saturation can be calculated.
[0041] In one embodiment of the present invention, a control display panel 9 is fixedly connected to the outside of the monitoring block 15. The control display panel 9 is used to control function options and display blood oxygen saturation.
[0042] In one embodiment of the present invention, a battery is disposed inside the earplug fixing head 1 to supply power to the electronic components of the entire probe, making the entire device convenient to carry out for use.
[0043] In one embodiment of the present invention, a data interface 14 is provided on the outer side of the earplug fixing head 1. On the one hand, it can be used to transmit signals to connect with external devices, and on the other hand, it can be used to charge the battery.
[0044] In one embodiment of the present invention, a connecting line 12 is further included, one end of which is fixedly connected to a first data connector 11 adapted to a data interface 14, and the other end of which is fixedly connected to a second data connector 13 connected to an external device. When it is necessary to connect to an external device, the connecting line 12 is used to transmit signals and is detachable for easy carrying.
[0045] It should be noted that the metal gooseneck tube and the plastic semi-arc circular tube in the present application have wiring harnesses running inside, which are used to electrically connect the electronic devices inside the monitoring probe to facilitate power supply and signal transmission.
[0046] In one embodiment of the present invention, the distance between the two plastic cards 10 is 3 mm, which can not only clamp the earlobe but also avoid excessive clamping.
[0047] In one embodiment of the present invention, the outer surfaces of the plastic semi-arc circular tube 5, the first soft plastic circular tube 4 and the second soft plastic circular tube 7 are marked with identification lines 6. The degree of distortion of the first soft plastic circular tube 4 and the second soft plastic circular tube 7 can be observed intuitively.
