AI Technical Summary
The existing pulse oxygen probe is not suitable for limb surgery, which leads to inconvenience in monitoring and increases the risk of surgery. Especially when surgery on both hands or limbs, the existing probe cannot be stable, affecting the monitoring effect.
An earlobe type vein oxygen probe structure is designed, including a lead wire and a fixing clip connected to an anesthesia machine, which is sandwiched at the patient's earlobe, and compact fixation is achieved using a rotating shaft and torsion spring. The working end of the splint is roundly fitted to the earlobe, and a pulse oxygen probe element is embedded.
It has achieved stable monitoring of peripheral pulse oxygen saturation during limb surgery, liberating the patient's limbs, simplifying operations, and reducing surgical risks.

Abstract
Description
Technical Field
[0001] The utility model relates to a structure of an earlobe - type pulse oximetry probe. Background Art
[0002] During anesthesia work, it is necessary to detect the pulse oxygen saturation of the peripheral circulation of the surgical patient during the operation. Generally, a finger pulse oximetry detector is used, which is put on the finger and the lead wire is connected to the anesthesia machine. However, for some patients who need to have surgery on both hands, at this time, the monitor can only be connected to the toes. The existing probe shapes and sizes are not suitable for the toes, which are often inconvenient, the lead wires are not long enough, and are prone to falling off, increasing the risks for patients during the operation. For some patients who need limb surgery and must retain one limb to monitor the pulse oxygen saturation, they have to disinfect and operate in batches, which brings great inconvenience to the operation. Content of the Utility Model
[0003] The purpose of the utility model is to provide a structure of an earlobe - type pulse oximetry probe. The earlobe - type pulse oximetry probe has a compact structure, can be clipped on the earlobe of a patient, is used for monitoring peripheral pulse oxygen saturation, liberates the limbs of the surgical patient, and is convenient for the operation of special surgical patients.
[0004] The technical solution of the utility model lies in: a structure of an earlobe - type pulse oximetry probe, including a lead wire connected to an anesthesia machine. One end of the lead wire is provided with a fixed clip for clipping on the earlobe. The fixed clip includes two clamping plates rotatably connected by a rotating shaft. A torsion spring with one end abutted against one of the clamping plates is sleeved on the rotating shaft, and the other end of the torsion spring is abutted against the other clamping plate. A pulse oximetry probe element connected to the lead wire is arranged on the clamping surface of the working end of one of the clamping plates of the fixed clip.
[0005] Further, both clamping plates are provided with working ends extending forward, the working ends are circular, and the pulse oximetry probe element is embedded in the working end of one of the clamping plates.
[0006] Further, one end of the lead wire is fixedly connected to one of the clamping plates of the fixed clip through a fixed block.
[0007] Further, the fixed clip is made of plastic.
[0008] Compared with the prior art, the utility model has the following advantages: the earlobe - type pulse oximetry probe has a compact structure, can be clipped on the earlobe of a patient, is used for monitoring peripheral pulse oxygen saturation, helps to liberate the limbs, is convenient for the operation of special surgical patients, and is simple to operate and use.

[0012] To make the above features and advantages of the present utility model more understandable, specific embodiments are hereinafter given and described in detail in conjunction with the accompanying drawings, but the present utility model is not limited thereto.
[0013] Reference Figure 1 And Figure 2
[0014] An earlobe - type pulse oximetry probe structure includes a lead wire 10 connected to a pulse oximetry detection instrument 1 of an anesthesia machine. One end of the lead wire is provided with a fixing clip 20 for clamping on the earlobe. The fixing clip includes two clamping plates 22 rotatably connected through a rotating shaft 21. A torsion spring 23 with one end abutted against one of the clamping plates is sleeved on the rotating shaft, and the other end of the torsion spring is abutted against the other clamping plate. A pulse oximetry probe element 30 connected to the lead wire is arranged on the clamping surface of the working end of one of the clamping plates.
[0015] In this embodiment, wing plates 26 are arranged on both sides of the middle part of the clamping plates, and the two pairs of wing plates of the two clamping plates are rotatably connected through a rotating shaft.
[0016] In this embodiment, the clamping plates are both provided with working ends 24 extending forward. When the working ends of the two clamping plates are closed, they are in close contact. The working ends are circular, so as to better fit the earlobe. The pulse oximetry probe element is embedded in the working end of one of the clamping plates.
[0017] In this embodiment, one end of the lead wire is fixedly connected to one of the clamping plates of the fixing clip through a fixed block 25, so as to realize the connection and fixation between the lead wire and the fixing bracket.
[0018] In this embodiment, the fixing clip is made of plastic, specifically, it can be made of antibacterial plastic.
[0019] If the present utility model discloses or involves components or structural parts that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connected by bolts or screws), or it can also be understood as: an inseparable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integral structure (for example, manufactured integrally by casting process) (except when it is obviously impossible to adopt the integral forming process).
[0020] Any component provided by the present utility model can either be assembled from multiple separate components or be a single component manufactured by an integral forming process.
[0021] The above are only the preferred embodiments of the present utility model, and all equivalent changes and modifications made according to the scope of the patent application of the present utility model shall fall within the scope covered by the present utility model.
