Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a blood leakage monitoring patch structure and a blood leakage monitoring device. Background Technology

[0002] In clinical settings such as hemodialysis, postoperative drainage, and intensive care, bleeding from puncture sites or wounds is a common risk, which can lead to hemorrhagic shock in severe cases. Therefore, real-time and sensitive monitoring of blood leakage is necessary.

[0003] Currently, blood leakage monitoring patches are commonly used to monitor blood leakage at clinical puncture sites or wounds in real time. The basic principle is to use a patch attached to the skin surface, combined with absorbent material and electrodes, to detect blood leakage. When blood leaks, it spreads across the absorbent material. When it reaches the electrode location, a pair of electrodes become electrically connected through the blood, opening the pathway between the electrodes and the host computer. Based on this connection signal, the computer determines that blood leakage has occurred and triggers an alarm.

[0004] Most current blood leakage monitoring patches use adhesives to attach electrodes to the patch and absorbent sheet. However, the patient's skin surface is often moist with sweat, tissue fluid, and other factors, which significantly weakens the adhesive's adhesion. Over extended monitoring periods, this can easily lead to the electrodes peeling off from the patch and absorbent sheet. When peeling occurs, the electrodes cannot effectively contact the blood, resulting in monitoring failure. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a blood leakage monitoring patch structure and a blood leakage monitoring device to solve the problem that the existing blood leakage monitoring patch structure is prone to the risk of the electrodes peeling off from the patch and the absorbent sheet during use, resulting in insufficient monitoring reliability.

[0023] To address the problem of insufficient monitoring reliability caused by the risk of electrode detachment from the patch and absorbent material in existing blood leakage monitoring patches, this invention provides a blood leakage monitoring patch structure. The patch includes an adhesive tape, absorbent cotton cores disposed on a first and a second side of the tape, and a detection electrode. The adhesive tape has limiting holes, and utilizing the space provided by the physical thickness of the absorbent cotton core, a snap-fit ​​mechanism extending from the tape is provided on the detection electrode. The detection electrode is secured to the adhesive tape via the snap-fit ​​mechanism and the limiting holes. This mechanical fixation of the tape and detection electrode effectively improves the fixation between the detection electrode and the tape, thereby ensuring reliable contact between the detection electrode and the absorbent cotton core, and ultimately guaranteeing the reliability of blood leakage detection.

[0024] Specifically, please refer to Figures 1 to 8 In this embodiment, the blood leakage detection patch structure works in conjunction with the monitoring host, including a plug module 100, a cable 200, and a patch module 300. The patch module 300 detects blood leakage, and the blood leakage signal is transmitted to the monitoring host through the cable 200 and the plug module 100. The monitoring host identifies the blood leakage and triggers an alarm.

[0025] The patch module 300 includes an adhesive tape 310, an absorbent core 320, a release paper 330, and a protective film 340. The absorbent core 320 is fixed to the first side of the adhesive tape 310, and a detection electrode 220 is provided on the second side of the adhesive tape 310. The detection electrodes 220 are arranged in pairs at intervals, and multiple pairs can be set according to monitoring requirements.

[0026] Release paper 330 is attached to the first side of adhesive tape 310, holding absorbent cotton core 320 in between for protection. When in use, the release paper 330 is peeled off, and absorbent cotton core 320 is attached to the patient's skin along with adhesive tape 310 to absorb any possible blood leakage.

[0027] The protective sticker 340 is fixed to the second side of the tape 310, at least completely covering the detection electrode 220, so that the conductive exposed area of ​​the detection electrode 220 is clamped and protected between the protective sticker 340 and the tape 310. The protective sticker 340 can be made of protective foam, which is insulating and waterproof, and can be effectively fixed to the tape 310 by adhesive, ensuring the protection effect of the detection electrode 220.

[0028] The absorbent cotton wick 320 and the detection electrode 220 are respectively disposed on both sides of the adhesive tape 310. To achieve contact between the detection electrode 220 and the absorbent cotton wick 320, so that the absorbent cotton wick 320 can absorb the leaked blood, and to achieve electrical connection of the detection electrode 220, in this embodiment, as shown... Figure 2 As shown (exploded view after flipping), the tape 310 also has a limiting hole 311, and the absorbent cotton core 320 at least covers the limiting hole 311; as Figure 3 , Figure 4 and Figure 5 As shown ( Figure 3 and Figure 4 Opposite perspective, Figure 5 and Figure 4 (Same viewing angle), the detection electrode 220 includes a snap-fit ​​mechanism 221 extending into the tape 310. The snap-fit ​​mechanism 221 passes through the limiting hole 311 and engages with it to lock and fix the detection electrode 220 to the tape 310. After passing through the limiting hole 311, the snap-fit ​​mechanism 221 contacts the absorbent cotton core 320 on the first side of the tape 310, achieving contact between the detection electrode 220 and the absorbent cotton core 320. Simultaneously, as... Figure 5 As shown, after the V-shaped main body of the buckling mechanism 221 passes through the limiting hole 311, it is limited to the other side of the tape 310, thereby realizing the mechanical locking and fixing of the detection electrode 220 and the tape 310.

[0029] The detection electrode is set by passing through the tape via a snap-fit ​​mechanism, which allows the main body of the detection electrode to be placed on the second side of the tape. The tape isolates the detection electrode from moisture factors such as sweat and tissue fluid on the patient's body surface, further improving the fixation effect between the main body of the detection electrode and the tape.

[0030] Considering the limited thickness of the absorbent cotton core 320, in this embodiment, the locking mechanism 221 includes a V-shaped buckle that extends horizontally. This can reduce the height of the locking mechanism 221 while ensuring the locking effect, making installation easier. In addition, the large surface area of ​​the V-shaped buckle facilitates full contact with the absorbent cotton core 320, improving the reliability of contact with the blood leakage absorbed by the absorbent cotton core 320 and ensuring the reliability of detection.

[0031] To ensure the stability of the locking mechanism, in this embodiment, the locking mechanism 221 is symmetrically arranged on both sides of the detection electrode 220.

[0032] To facilitate the connection between the detection electrode 220 and the cable 200, in this embodiment, one end of the detection electrode 220 further includes an extended second clamping mechanism 222. Two sets of the second clamping mechanism 222 are provided, respectively matching the insulation area of ​​the cable 200 and the exposed core 201. After the cable 200 is inserted, the second clamping mechanism 222 clamps and secures the cable 200, achieving electrical connection between the core 201 of the cable 200 and the detection electrode 220. To improve the reliability of the fixation, the core 201 and the detection electrode 220 can also be welded together, further enhancing the reliability of the fixation.

[0033] The detection electrode 220 is connected to the plug module 100 via cable 200, and then connected to the monitoring host via the plug module 100. For example... Figures 6 to 8 As shown, the plug module 100 includes a base 120 and a top cover 110. An electrode lead-out window 122 is provided on the base 120. The connecting electrode 210 at the end of the cable 200 is clamped and fixed between the base 120 and the top cover 110 and exposed and led out through the electrode lead-out window 122. The connecting electrode 210 and the detection electrode 220 are connected one-to-one, and the detection electrode 220 is connected to the monitoring host.

[0034] To facilitate the fixing of the connecting electrode 210, in this embodiment, the connecting electrode 210 has a convex bending structure, and its protruding contact area 212 contacts the contact electrode inside the connector of the monitoring host. The upper cover 110 is provided with a mounting boss 112 that conforms to the convex bending structure (the contact mating surfaces are all convex bending structures, allowing for a close fit). The boss area of ​​the mounting boss 112 is aligned with the electrode lead-out window 122 and the contact area 212 of the connecting electrode 210. The stepped areas at both ends of the mounting boss 112 are provided with positioning grooves. The base 120 is provided with positioning posts 121 that are aligned with the positioning grooves, and the connecting electrode 210 is provided with openings 211 that are aligned with the positioning grooves. The base 120 and the upper cover 110 can be snapped together for assembly. The opening on the connecting electrode 210 is pre-assembled with the positioning post 121 on the base 120, and then the upper cover 110 is closed and pressed to fix it.

[0035] A first clamp mechanism 213 is provided at one end of the connecting electrode 210, and the first clamp mechanism 213 is connected to the wire core 201 of the cable 200. In order to facilitate the plug module 100 insertion and removal operation, in this embodiment, the cable terminal of the upper cover 110 is provided with an extended support plate 111. The size of the support plate 111 is larger than the diameter of the cable 200, serving as a holding part to facilitate the plug module 100 insertion and removal operation and avoid the problem of the wire core 201 falling off the connecting electrode 210 due to direct pulling of the cable 200.

[0036] This utility model also provides a blood leakage monitoring device, including a monitoring host and the aforementioned blood leakage monitoring patch structure, wherein the detection electrodes of the blood leakage monitoring patch structure are electrically connected to the monitoring host.

[0037] The blood leakage monitoring patch structure and blood leakage monitoring device provided by this utility model have limiting holes on the adhesive tape, and utilize the setting space provided by the physical thickness of the absorbent cotton core. A buckle mechanism extending from the adhesive tape is set on the detection electrode. The detection electrode is locked and fixed to the adhesive tape by the buckle mechanism and the limiting holes. Through mechanical fixation, the fixing effect between the detection electrode and the adhesive tape can be effectively improved, thereby ensuring the reliability of the contact between the detection electrode and the absorbent cotton core, ensuring the reliability of blood leakage detection, and thus improving the reliability of medical blood leakage monitoring and ensuring medical safety.
