[0034] The following will be described in detail in combination with the accompanying drawings Figures 1-3 Further detailed description of the present application, the embodiment of the present application discloses a kind of blood oxygen saturation detection clamp.

[0035] Refer to Figure 1 And Figure 2 As shown in a kind of blood oxygen saturation detection clamp, including shell 100 and sticking assembly 200. The center of shell 100 is through the opening of accommodating cavity 110, the accommodating cavity 110 is specially used to accommodate and fix the detection part (such as finger, wrist and ankle, etc.) of patient. Accommodating cavity 110 is opened by one end of shell 100, so that user can easily put or take out the detection part. Shell 100 includes C-shaped plate 120 and two rotating plates 130, two rotating plates 130 are rotationally arranged at the two ends of C-shaped plate 120 to form U-shaped setting shell 100.

[0036] And rotating plate 130 and C-shaped plate 120 are provided with rotating assembly 300 for facilitating rotating plate 130 to adjust the rotation angle, to ensure the stability and accuracy of detection part in the measuring process. Not only increase the comfort of user, but also ensure the good contact between sensor and skin in the process of blood oxygen saturation detection, improve the signal transmission efficiency.

[0037] The sticking assembly 200 is provided with at least two groups, that is, at least one group of sticking assembly 200 is installed on each rotating plate 130, and the sticking assembly 200 is installed on the opposite side wall of the two rotating plates 130. The inner side of each rotating plate 130 is provided with a connecting assembly 400 for binding the patient. It is ensured that the detection clamp can maintain stability under various conditions, and even in the case of patient movement, a good contact state can be maintained to avoid signal loss.

[0038] The rotating plate 130 is adjusted to rotate and stick to the patient's skin. The rotating plate 130 can move with the patient's skin and bend slightly with the ups and downs of the patient's skin, thereby avoiding the problem of traditional clamping and extrusion.

[0039] Referring to Figure 2 and Figure 3 , the rotating assembly 300 includes a rotating shaft 310 and two rotating sleeves 320. The rotating shaft 310 is fixedly connected to the end of the C-shaped plate 120, and the axial length of the rotating shaft 310 is parallel to the through direction of the accommodating cavity 110 of the C-shaped plate 120. The two rotating sleeves 320 are fixedly connected to the ends of the rotating plate 130 and are sleeved on the rotating shaft 310 and are rotatably arranged. The rotating plate 130 is freely rotatable. In this way, the rotating plate 130 can be flexibly adjusted according to actual needs to adapt to the physiological characteristics of different users, especially for users with different finger thicknesses, to provide a more personalized wearing experience.

[0040] A first torsional spring is installed on the rotating shaft 310, which is used to drive the rotating plate 130 on the rotating shaft 310 to flip towards the center of the C-shaped plate 120, and the rotating plate 130 is initially arranged in the vertical direction of the end of the C-shaped plate 120 under the action of the torsional spring. The function of the first torsional spring is to generate a restoring force to make the rotating plate 130 have a tendency to flip towards the center of the C-shaped plate 120 without external force, to ensure the stable state of the rotating plate 130, and to prevent the detection clamp from being accidentally loosened to a certain extent, thereby ensuring the reliability of long-term monitoring.

[0041] Referring to Figure 1 and Figure 2 , the sticking assembly 200 includes a replacement plate 220 and a sticking strip 230. The inner side of the rotating plate 130 is provided with a sliding groove 210, which is specially designed in a dovetail groove shape. The dovetail groove is arranged along the through direction of the accommodating cavity 110 of the rotating plate 130, but does not completely penetrate through the entire rotating plate 130, but a certain closed end is reserved. The replacement plate 220 is slidably installed in the sliding groove 210, that is, the rotating plate 130 is inserted from one side of the dovetail groove and abuts against the side wall of the dovetail groove, so that the replacement plate 220 can be stably positioned in the rotating plate 130, effectively preventing the replacement plate 220 from falling off during use.

[0042] The dovetail groove has notches on the opposite side walls of the two rotating plates 130. When the replacement plate 220 is inserted into the dovetail groove, the rotating plate 130 protrudes from the notch, and the adhesive strip 230 is attached to the part of the replacement plate 220 that protrudes from the notch, so as to facilitate the installation and replacement of the adhesive strip 230.

[0043] Since the adhesive strip 230 comes into direct contact with the patient's skin, the selection of the biocompatibility and adhesive strength of the adhesive strip 230 is to ensure that it can be firmly fixed to the skin during the testing process, avoiding inaccurate data due to movement.

[0044] When the adhesive strip 230 needs to be replaced, the user simply pulls the replacement plate 220 to slide it out along the dovetail groove, easily removing the old adhesive strip 230 and installing the new one. This design greatly simplifies the cleaning and maintenance process, improving ease of use and hygiene.

[0045] Reference Figure 2 and Figure 3 As shown, the connecting assembly 400 includes a connecting strap 440, a fixed shaft 420, and a storage cylinder 430. The rotating plate 130 has internal receiving grooves 410 for accommodating the connecting assembly 400. The rotating plate 130 also has a connecting port for connecting to the outside, which is connected to the receiving groove 410. A recessed groove 450 is formed at the end of the rotating plate 130 away from the C-shaped plate 120, and the recessed groove 450 is connected to the receiving groove 410. The fixed shaft 420 is fixedly connected to the inside of the receiving groove 410, and the axial direction of the fixed shaft 420 is perpendicular to the through direction of the receiving cavity 110.

[0046] A storage cylinder 430 is rotatably mounted on a fixed shaft 420. One end of a connecting strap 440 is wound around the storage cylinder 430, while the other end extends outward through the connecting opening and the slot 450. A second torsion spring is mounted on the fixed shaft 420, which drives the storage cylinder 430 to rotate and wind up the connecting strap 440. The elastic potential energy of the spring drives the storage cylinder 430 to rotate, thereby automatically winding up the slack connecting strap 440. When the connecting strap 440 is subjected to external tension, it is released from the storage cylinder 430; when the external tension disappears, the elastic force of the second torsion spring causes the storage cylinder 430 to rotate in the opposite direction, automatically retracting the connecting strap 440. This mechanism effectively reduces the tangled state of the connecting strap 440, maintains a clean working environment, and extends the service life of the connecting strap 440.

[0047] The outer ends of the connecting bands 440 on the two connecting assemblies 400 are respectively connected with mutually matched Velcro 460, the width and thickness of the Velcro 460 are greater than the width and thickness of the connecting bands 440, and the Velcro 460 is clamped in the embedding groove 450, so that the fixing effect of the connecting bands 440 is strengthened, the connecting bands 440 are prevented from being sucked into the containing groove 410 in the automatic winding process, the connecting operation of the user is simplified, the fixing or release of the connecting bands 440 can be completed by gently pressing, and the convenience and efficiency of use are greatly improved.

[0048] The inner wall of the shell 100 is further fixedly installed with cloth 140 for contacting the skin of the patient, the cloth 140 is wrapped on the C-shaped plate 120 and part of the rotating plate 130 respectively, so that additional softness is provided in the detection clamp clamping process, and the pressure on the skin of the patient is reduced. The cloth 140 is preferably a medical-grade cloth 140 with good skin-friendliness and strong air permeability, which can effectively reduce skin allergy or discomfort caused by long-term contact. In addition, the cloth 140 also has good moisture absorption and sweat release performance, and can keep the contact area dry even during a long period of use, improving the user experience of the patient.

[0049] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
