Abstract
Description
Technical Field
[0001] This utility model belongs to the field of blood oxygen detection technology, specifically relating to a disposable blood oxygen detection probe fixing device that is adaptable to multiple locations. Background Technology
[0002] Disposable pulse oximeter probes are commonly used in medical monitoring, primarily for measuring blood oxygen saturation and pulse rate. As shown in patent application number CN202510293632.X, the disposable pulse oximeter probe is elongated and, in clinical applications, is typically fixed to the patient's finger or head. However, most existing technologies use adhesive tape for fixation, which presents several problems. For example, in agitated patients, frequent finger movements can easily cause the probe to fall off, affecting the continuity of monitoring. Furthermore, prolonged use of the probe in the same location may cause skin pressure, affecting blood circulation and consequently the accuracy of the monitoring results. Some patients may experience discomfort after prolonged use and need to change the fixation position, but adhesive tape easily loses its stickiness when soaked with sweat, resulting in insecure fixation. Furthermore, the lost adhesive tape cannot be re-adheded after changing the position. Therefore, existing technologies suffer from the problem of insecure fixation of disposable pulse oximeter probes and the inconvenience of changing the fixation position between the finger and forehead. Utility Model Content
[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a disposable pulse oximetry probe fixing device that is adaptable to multiple body parts, thus solving the problems of unstable fixing of disposable pulse oximetry probes and inconvenience in changing the fixing position between the finger and the forehead in existing technologies.
[0004] The objective of this utility model can be achieved through the following technical solutions:
[0005] A multi-site adaptable disposable pulse oximetry probe fixing device for fixing a strip-shaped disposable pulse oximetry probe to a patient's forehead or finger, including an annular elastic band loop;
[0006] The elastic band ring has a first connecting part on its inner side and a second connecting part on one side of the disposable blood oxygen detection probe. The first connecting part and the second connecting part are detachably connected.
[0007] When the disposable pulse oximeter probe is placed inside the elastic band loop and the disposable pulse oximeter probe is placed in the same direction as the central axis of the elastic band loop, the elastic band loop is used to wrap around the patient's finger and fix the disposable pulse oximeter probe to the patient's finger.
[0008] When the disposable pulse oximeter probe is placed inside the elastic band ring, and the disposable pulse oximeter probe is placed perpendicular to the central axis of the ring, and the first connecting part is connected to the second connecting part, the elastic band ring is used to fix the disposable pulse oximeter probe on the patient's forehead.
[0009] The first connecting part includes a first hook-face sticker and a first fleece-face sticker fixed on the inner peripheral wall of the elastic band ring. The first hook-face sticker and the first fleece-face sticker are placed side by side, and both the first hook-face sticker and the first fleece-face sticker are placed parallel to the central axis of the ring where the elastic band ring is located.
[0010] The second connecting part includes a second hook-shaped sticker and a second fleece-shaped sticker that are placed side by side and fixed on the same side of the disposable pulse oximetry probe;
[0011] The first hook-on sticker, the first velvet sticker, the second hook-on sticker, and any of the second velvet stickers can be adhered to any velvet sticker;
[0012] When the first hook-on sticker and the first fleece sticker are bonded together, the elastic band loop is divided into a large band loop and a small band loop. The small band loop is used to be fitted on the outside of the patient's finger and the disposable pulse oximetry probe. When the small band loop is fitted on the patient's finger, the elastic bands corresponding to the small band loop are all in a stretched state.
[0013] There are multiple first hook-on stickers and multiple first fleece stickers. The number of first hook-on stickers and first fleece stickers are equal and correspond one-to-one.
[0014] The second hook face sticker and the second velvet face sticker are both arranged in multiple parallel rows, and the number of the second hook face sticker or the second velvet face sticker is less than or equal to the number of the first hook face sticker.
[0015] The elastic band ring has multiple vent holes. When the elastic band ring is in a stretched state, the diameter of the vent holes increases.
[0016] The spacing between two adjacent first hook face patches is less than or equal to the spacing between two adjacent second fleece face patches; the spacing between two adjacent first fleece face patches is less than or equal to the spacing between two adjacent second hook face patches.
[0017] The elastic band loops are made of medical-grade silicone.
[0018] The beneficial effects of this utility model are:
[0019] 1. By using the elastic band ring, the first hook sticker, the first fleece sticker, the second hook sticker and the second fleece sticker in combination, the disposable pulse oximetry probe can be selectively fixed to the forehead or finger according to actual needs. At the same time, it effectively improves the stability of the disposable pulse oximetry probe after it is fixed, and facilitates the subsequent replacement of the fixing position between the finger and the forehead.
[0020] 2. The elastic band loop is separated into small loops by the adhesion between the first hook-shaped adhesive and the first felt-like adhesive. The elastic band in the stretched state of the small loops presses the disposable pulse oximetry probe tightly onto the patient's finger, thereby improving the stability of the disposable pulse oximetry probe fixed on the finger.
[0021] 3. By setting multiple first hook-shaped adhesive strips and first fleece-shaped adhesive strips, the appropriate first hook-shaped adhesive strip and first fleece-shaped adhesive strip can be selected according to the different thicknesses of the patient's fingers, and they can be bonded together with the elastic band loop to form a small band loop, so as to avoid the small band loop from causing excessive pressure on the patient's fingers.
[0022] 4. By setting multiple second hook-shaped stickers and second fleece-like stickers, the stability of the disposable pulse oximeter probe adhering to the inner wall of the elastic band ring is improved, effectively enhancing the stability of the disposable pulse oximeter probe fixed on the forehead.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0029] This combination Figures 1 to 4This document describes an embodiment of a multi-site adaptable disposable pulse oximetry probe fixation device. Specifically, the multi-site adaptable disposable pulse oximetry probe fixation device is constructed as a split structure, comprising components such as an elastic band loop 300, a first hook-and-loop fastener 400, a first fleece-like fastener 401, a second hook-and-loop fastener 200, and a second fleece-like fastener 201. It can selectively fix the disposable pulse oximetry probe 100 to the patient's forehead or finger, and provides good stability after fixation, effectively reducing the risk of accidental dislodgement of the disposable pulse oximetry probe 100.
[0030] Please refer to Figures 1 to 4 A multi-site adaptable disposable pulse oximetry probe fixing device for fixing a strip-shaped disposable pulse oximetry probe 100 to a patient's forehead or fingers, including an annular elastic band loop 300.
[0031] The elastic band loop 300 has a first connecting part on its inner side, and the disposable blood oxygen detection probe 100 has a second connecting part on one side. The first connecting part and the second connecting part are detachably connected.
[0032] When the disposable pulse oximeter probe 100 is placed inside the elastic band ring 300, and the disposable pulse oximeter probe 100 and the central axis of the ring containing the elastic band ring 300 are placed in the same direction, the elastic band ring 300 is used to wrap around the patient's finger and fix the disposable pulse oximeter probe 100 to the patient's finger.
[0033] When the disposable pulse oximeter probe 100 is placed inside the elastic band ring 300, and the disposable pulse oximeter probe 100 is perpendicular to the central axis of the ring containing the elastic band ring 300, and the first connecting part is connected to the second connecting part, the elastic band ring 300 is used to fix the disposable pulse oximeter probe 100 to the patient's forehead.
[0034] The first connecting part includes a first hook-face sticker 400 and a first fleece sticker 401 fixed on the inner peripheral wall of the elastic band ring 300. The first hook-face sticker 400 and the first fleece sticker 401 are placed side by side, and both the first hook-face sticker 400 and the first fleece sticker 401 are placed parallel to the central axis of the ring where the elastic band ring 300 is located.
[0035] The second connecting part includes a second hook-shaped adhesive 200 and a second fleece-shaped adhesive 201 that are placed side by side and fixed on the same side of the disposable pulse oximetry probe 100;
[0036] Any of the following hook-and-face stickers can be adhered to any one of the following hook-and-face stickers: first hook-and-face sticker 400, first velvet-and-face sticker 401, second hook-and-face sticker 200, and second velvet-and-face sticker 201.
[0037] 1. When using the elastic band loop 300 to fix the disposable pulse oximeter probe 100 onto the patient's finger, the specific steps are as follows:
[0038] Place your finger inside the elastic band ring 300, place the disposable pulse oximeter probe 100 on your finger and keep it in the same direction as your finger, so that the side of the disposable pulse oximeter probe 100 away from your finger contacts the inner peripheral wall of the elastic band ring 300.
[0039] Pinch the two strips of the elastic band ring 300 located below the fingers until they fit together. At this time, the elastic band ring 300 is away from the loop formed between the fingertips and the pinched area.
[0040] Then pinch the two sides of the band and pull it toward the finger. At this time, except for the elastic band loop 300 wrapped around the patient's finger, the rest of the elastic band loop 300 are all on the same side of the finger.
[0041] Pinch the two sides of the band and wrap it around the patient's finger, so that the two sides of the band are spirally wrapped around the patient's finger at the same time. When spirally wrapping, the elastic band ring 300 continuously covers the finger and the disposable blood oxygen detection probe 100, while the loop formed between the elastic band ring 300 and the pinching part away from the fingertip is continuously reduced.
[0042] Finally, after the remaining loop diameter is smaller than the finger diameter, the operator pulls the loop to expand it and inserts the patient's finger into the expanded loop, thus completing the fixation of the disposable blood oxygen detection probe 100 on the patient's finger.
[0043] II. When using the elastic band loop 300 to fix the disposable pulse oximetry probe 100 to the patient's forehead, the specific steps are as follows:
[0044] The first hook-and-loop sticker 400 is bonded to the second fleece sticker 201, and the first fleece sticker 401 is bonded to the second hook-and-loop sticker 200, so that the disposable pulse oximetry probe 100 is bonded and fixed to the inner wall of the elastic band ring 300. Then, the elastic band ring 300 is pulled to expand it and the elastic band ring 300 is placed on the patient's forehead. Through the elasticity of the elastic band ring 300, in conjunction with the bonding of the hook-and-loop sticker and the fleece sticker, the disposable pulse oximetry probe 100 is fixed to the patient's forehead.
[0045] According to clinical guidelines and operating procedures, to avoid skin pressure and impaired blood circulation, it is recommended to change the monitoring site every 1-2 hours.
[0046] This application, through the coordinated arrangement of the elastic band loop 300, the first hook-and-cover 400, the first fleece-cover 401, the second hook-and-cover 200, and the second fleece-cover 201, can selectively fix the disposable pulse oximetry probe 100 to the patient's forehead or fingers, and has good stability after fixation, which can effectively reduce the risk of the disposable pulse oximetry probe 100 accidentally falling off.
[0047] When the first hook-on patch 400 and the first fleece patch 401 are bonded together, the elastic band loop 300 is divided into a large loop and a small loop. The small loop is used to be fitted on the outside of the patient's finger and the disposable pulse oximetry probe 100. When the small loop is fitted on the patient's finger, the elastic bands corresponding to the small loop are all in a stretched state.
[0048] The disposable pulse oximeter probe 100 is pressed firmly onto the patient's finger by the elastic band of the small loop being placed on it and stretched.
[0049] Multiple first hook-face stickers 400 and first fleece-face stickers 401 are provided, with an equal number of first hook-face stickers 400 and first fleece-face stickers 401 that correspond one-to-one. Depending on the thickness of the patient's fingers, appropriate first hook-face stickers 400 and first fleece-face stickers 401 can be selected and adhered together with the elastic band ring 300 to form a small band ring, thus avoiding excessive pressure on the patient's fingers caused by the small band ring.
[0050] The second hook-face sticker 200 and the second fleece-face sticker 201 are both arranged in parallel, and the number of the second hook-face sticker 200 or the second fleece-face sticker 201 is less than or equal to the number of the first hook-face sticker 400; to improve the stability of the disposable blood oxygen detection probe 100 adhering to the inner wall of the elastic band ring 300.
[0051] The elastic band ring 300 has multiple ventilation holes 301. When the elastic band ring 300 is in a stretched state, the diameter of the ventilation holes 301 increases. The ventilation holes 301 improve the air permeability of the elastic band ring 300.
[0052] The spacing between two adjacent first hook-face patches 400 is less than or equal to the spacing between two adjacent second fleece-face patches 201, and the spacing between two adjacent first fleece-face patches 401 is less than or equal to the spacing between two adjacent second hook-face patches 200; this ensures that after the elastic band ring 300 is stretched, the disposable blood oxygen detection probe 100 can be adhered to the inner wall of the elastic band ring 300 through the adhesion of the fleece-face patch and the hook-face patch.
[0053] The elastic band loop 300 is made of medical-grade silicone; silicone has good biocompatibility and elasticity, and can adapt to the skin conditions of different patients.
