Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically to a battery box for a human telemetry electrocardiogram monitor. Background Technology

[0002] Telemetry cardiac monitoring utilizes remote sensing technology to monitor a patient's heart remotely and continuously over a large area, simultaneously monitoring multiple subjects. It observes cardiac electrical activity, records electrocardiogram waveforms, and calculates heart rate values. This allows for the identification of abnormal cardiac activity, assessment of chest pain, monitoring of drug efficacy, and detection of symptoms related to cardiac activity.

[0003] The telemetry ECG monitor is worn on the patient, who can move freely within the effective range. Medical staff can fully grasp the patient's heart rhythm and ST segment changes at various time periods. The computer can be used to analyze and record the patient's arrhythmia, providing a comprehensive 24-hour monitoring information.

[0004] For ease of use by patients, telemetry ECG monitors are typically small and square, containing multiple AAA or AA batteries connected in parallel. Since each patient is monitored for up to 24 hours at a time, the batteries deplete quickly and require frequent replacement. The batteries are usually located on the back of the telemetry ECG monitor. Figure 1 As shown, the existing battery compartment has copper foil with a thickness of less than 0.1mm pasted at intervals on both sides (i.e., the left and right sides) as electrodes, which are in close contact with the positive and negative terminals of the dry cell battery. Copper foil is used because it is lightweight and can fit well against the inner wall of the battery compartment. However, due to the high frequency of battery replacement, the copper foil electrodes are prone to wear, deformation, and detachment after repeated battery insertion and removal, resulting in poor battery contact and rendering the monitor unusable. This greatly reduces the lifespan of the telemetry ECG monitor and also requires patients to repeatedly replace the device during use.

[0005] Therefore, there is a need to develop a battery box for a telemetry ECG monitor that is simple in structure, easy to use, and has a long electrode life. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the aforementioned background technology and provide a remote electrocardiogram monitor battery box that is simple in structure, easy to use, and has a long electrode lifespan. By setting thick copper electrodes inside the battery box, it has good wear resistance for high-frequency battery handling. The copper electrodes are clamped to the side wall of the battery box by their own inverted U-shaped structure, resulting in high stability of the entire electrode structure. It is not easily deformed or displaced during use, thus improving its service life.

[0007] The technical solution of this utility model is: a battery box for a telemetry electrocardiogram monitor, including a receiving cavity disposed on the back of the telemetry electrocardiogram monitor and a battery box disposed in the receiving cavity. The battery box includes a pair of first side plates arranged laterally opposite each other and a pair of second side plates arranged longitudinally opposite each other.

[0008] Each first side plate has multiple electrode grooves on its inner wall for corresponding to multiple batteries. The electrode grooves extend upward to the top of the first side plate. Each first side plate has an inverted U-shaped copper electrode at each electrode groove. The two arms of the inverted U-shape of the copper electrode are clamped on the inner and outer sides of the first side plate, and the inner arm extends downward into the electrode groove.

[0009] The inner wall of the cavity is provided with a limiting structure to vertically limit the battery box.

[0010] Preferably, the outer wall of the first side plate is provided with an outer wall groove corresponding to the groove of each electrode sheet, and each outer wall groove extends upward to the top of the first side plate, and the outer one of the two arms of the inverted U-shape of the copper electrode enters the outer wall groove downward.

[0011] Preferably, the limiting structure includes first limiting teeth arranged on the lateral opposite side walls of the receiving cavity. The first limiting teeth are multiple teeth arranged longitudinally at intervals. The first limiting teeth cooperate with the top of the first side plate to vertically limit the battery box.

[0012] Furthermore, each first limiting tooth is longitudinally located between two adjacent electrode grooves, and the top of the first side plate is provided with a mating part corresponding to the first limiting tooth between two adjacent electrode grooves.

[0013] Furthermore, the mating part is a limiting plane formed at the top of the first side plate.

[0014] Furthermore, the mating part is a slot provided on the top of the first side plate, and the slot extends laterally outward to the outer wall of the first side plate.

[0015] Furthermore, the limiting structure also includes second limiting teeth disposed on the longitudinally opposite side walls of the receiving cavity, the second limiting teeth cooperating with the top of the second side plate to vertically limit the battery box.

[0016] Preferably, the copper electrode is obtained by bending a copper sheet with a thickness of 0.5 to 1.5 mm.

[0017] Preferably, the inner end of one of the two arms of the inverted U-shape of the copper electrode is flush with the bottom of the electrode groove.

[0018] Preferably, the outer wall of the first side plate is provided with insulating tape to adhere the copper sheet electrodes to the first side plate. The insulating tape is a single piece and completely covers the lower ends of the outer arms of all copper sheet electrodes on each of the first side plates.

[0019] The beneficial effects of this utility model include:

[0020] 1. The copper electrode is made of thickened copper sheet in an inverted U-shape, which can be clamped onto the first side plate with its shape facing downwards. The thicker copper electrode also has good wear resistance, preventing deformation and detachment during frequent battery handling. The copper electrode can also cooperate with the electrode groove on the first side plate, which limits its position and maintains stability during battery placement and removal, reducing the occurrence of poor battery contact and greatly extending the service life of the telemetry ECG monitor.

[0021] 2. An outer wall groove can be provided on the outer wall of the first side plate as required. At this time, the two arms of the copper sheet electrode enter the outer wall groove and the electrode groove respectively, which further ensures the stable connection of the copper sheet electrode on the first side plate.

[0022] 3. The cavity is also equipped with a limiting structure to vertically limit the battery box. The first limiting tooth is set between the electrode grooves. While limiting the battery box, it avoids contact and scratching with the copper electrode, ensuring the normal operation of the copper electrode and reducing the occurrence of poor battery contact.

[0023] 4. A second limiting tooth can also be set inside the receiving cavity as needed. The second limiting tooth and the first limiting tooth simultaneously limit the battery box on all four sides, which can further limit the vertical position of the battery box and ensure a stable connection between the battery box and the receiving cavity when the patient is moving.

[0024] 5. The first side plate can be engaged with the first limiting tooth through the limiting plane or the slot at the top. The advantage of the limiting plane is that the structure is simple and can be used with the original top surface of the first side plate without adding any additional structure. The slot extends outward to the outer wall of the first side plate, and the first limiting tooth extends into the slot and is limited in the horizontal direction by the inner edge of the slot. At this time, the battery box is also restricted in the horizontal direction in the receiving cavity, and the connection between the two is more stable.

[0025] 6. The outer wall of the first side plate is provided with insulating tape to attach the copper electrode. The whole piece of insulating tape can not only protect the outer end of the copper electrode and the circuit solder joint, but also further stick the copper electrode to the first side plate and limit its position, so as to keep the position stable during the battery removal and placement process.

[0026] 7. The copper sheet electrode is made by bending a copper sheet with a thickness of 0.5 to 1.5 mm, ensuring that it has a certain degree of metallic elasticity and can be clamped to the first side plate; it also ensures abrasion resistance and prevents it from falling off and deforming. In the inverted U-shaped two arms of the copper sheet electrode, the outer arm is shorter than the inner arm, which saves material and also makes it easier to reserve space at the bottom of the outer arm for circuit connection.

[0037] The embodiments of this utility model are described in detail below, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0038] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0039] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0040] like Figure 1 The diagram shown is a schematic of the battery box on the back of a telemetry ECG monitor in the prior art. The copper foil used as electrodes is easily worn, deformed, and detached when the battery is frequently removed and placed, which can easily lead to poor battery contact and reduce the service life of the telemetry ECG monitor.

[0041] This invention addresses the problem by providing a remote electrocardiogram (ECG) monitor battery case that is simple in structure, easy to use, and has a long electrode lifespan. By incorporating thick copper electrodes within the battery case, it exhibits good wear resistance during high-frequency battery handling. The copper electrodes are secured to the side wall of the battery case via their inverted U-shaped structure, resulting in high stability of the entire electrode structure. This prevents deformation and displacement during use, thus extending the battery's lifespan.

[0042] The present application will be further described below with reference to specific embodiments.

[0043] Example 1

[0044] like Figure 2-6 As shown, this embodiment provides a battery box for a telemetry ECG monitor, including a receiving cavity 1 disposed on the back of the telemetry ECG monitor and a battery box 2 disposed within the receiving cavity 1. The battery box 2 includes a pair of first side plates 3 arranged laterally opposite each other and a pair of second side plates 4 arranged longitudinally opposite each other. In this embodiment, "lateral" refers to the length direction of the battery. Figure 2 The left and right directions are the same, and the vertical direction is the battery arrangement direction. Figure 2 From top to bottom.

[0045] Each first side plate 3 has multiple electrode grooves 5 on its inner wall for corresponding to multiple batteries. The electrode grooves 5 extend upward to the top of the first side plate 3. Each first side plate 3 has an inverted U-shaped copper electrode 6 at each electrode groove 5. The two arms of the inverted U-shape of the copper electrode 6 are clamped between the inner and outer sides of the first side plate 3, and the inner arm extends downward into the electrode groove 5.

[0046] In this embodiment, the battery box 2 is used to install three vertically arranged dry batteries. Therefore, there are three electrode grooves 5 and three copper electrode sheets 6. The inverted U-shaped copper electrode sheet 6 is obtained by bending a copper sheet with a thickness of 0.5 to 1.5 mm. This thickness of copper sheet has a certain degree of metallic elasticity, which can be clamped to the first side plate; it can also ensure abrasion resistance and prevent detachment and deformation. When the copper sheet material is bent into the copper electrode sheet 6, the two arms of the inverted U-shape can contact or approach each other. Therefore, when the copper electrode sheet 6 is installed downwards and inserted into the first side plate 3, the thickness of the first side plate 3 is used to spread the two arms of the copper electrode sheet 6, thereby ensuring that the copper electrode sheet 6 is firmly clamped to the first side plate 3. Each electrode groove 5 can limit the position of the copper electrode sheet 6, keeping its position stable during battery removal and placement.

[0047] The inner wall of the receiving cavity 1 is provided with a limiting structure for vertically limiting the battery box 2. The limiting structure includes first limiting teeth 9 arranged on the two side walls of the receiving cavity 1 laterally opposite each other. There are multiple first limiting teeth 9 arranged longitudinally at intervals. The first limiting teeth 9 cooperate with the top of the first side plate 3 to vertically limit the battery box 2. Each first limiting tooth 9 is longitudinally located between two adjacent electrode grooves 5. The top of the first side plate 3 is provided with a mating part corresponding to the first limiting tooth 9 between two adjacent electrode grooves 5. In this embodiment, the mating part is the limiting plane 8 formed on the top of the first side plate 3.

[0048] In this embodiment, the vertical direction is the depth direction of battery box 2, that is... Figure 2 The center is perpendicular to the direction shown in the drawing. There are two first limiting teeth 9 on each side, which are correspondingly set between two adjacent electrode grooves 5 of the three electrode grooves 5. When the battery box 2 is placed downwards, the outer wall of the first side plate 3 presses on the first limiting teeth 9 until the battery box 2 falls to the bottom of the receiving cavity 1. At this time, the limiting plane 8 of the first side plate 3 enters below the first limiting teeth 9 and cooperates with the first limiting teeth 9 to limit the position.

[0049] In some preferred embodiments, the limiting structure further includes second limiting teeth 11 disposed on the longitudinally opposite side walls of the receiving cavity 1. The second limiting teeth 11 cooperate with the top of the second side plate 4 to vertically limit the battery box 2. Both the first limiting teeth 9 and the second limiting teeth 11 are made of tough plastic. The battery box 2 inside the receiving cavity 1 can be pulled out upwards with force. Therefore, even if a copper electrode 6 is damaged over time, the battery box 2 can be removed and reinstalled.

[0050] In this embodiment, the copper electrode 6 is formed by bending a copper sheet with a thickness of 0.5 mm. The inner end of the two inverted U-shaped arms of the copper electrode 6 is flush with the bottom of the electrode groove 5, and the outer end of the two inverted U-shaped arms of the copper electrode 6 (… Figure 5 The left arm is shorter than the inner arm. Figure 5 The right arm (middle) saves materials and also facilitates the reserved space at the bottom of the outer arm for welding the connecting circuit 12.

[0051] Copper electrode 6 is arranged on the outer wall of the first side plate 3 as follows Figure 5-6 As shown, the bottom end of the outer arm of the copper electrode 6 is welded to the connecting circuit 12, thereby enabling power supply to the telemetry ECG monitor. In some preferred embodiments, insulating tape 13 can be used to attach the copper electrode 6 to the first side plate 3. The insulating tape 13 is a single piece, directly attaching all the copper electrodes 6 to the first side plate 3 from the outside. The insulating tape 13 can both protect the welded joint between the outer arm of the copper electrode 6 and the circuit, and further adhere the copper electrode 6 to the first side plate 3, limiting its position and ensuring its stability during battery removal and placement.

[0052] The installation process of the copper electrode 6 of this utility model is as follows: First, the copper sheet is bent into an inverted U-shaped copper electrode 6, keeping the two arms in contact or close together; the inner arm of the copper electrode 6 is aligned with the electrode groove 5 and inserted downwards into the first side plate 3. The thickness of the first side plate 3 is used to spread the two arms of the copper electrode 6, thereby ensuring that the copper electrode 6 is firmly clamped on the first side plate 3, and the end of the inner arm of the copper electrode 6 is flush with the bottom of the electrode groove 5. The lower end of the outer arm of the copper electrode 6 is soldered to the connection circuit 12 on the outer wall of the battery box 2. Then, a whole piece of insulating tape 13 is used to stick the three copper electrodes 6 to the outer wall of the first side plate 3. Finally, the battery box 2 containing the copper electrode 6 is placed face down into the receiving cavity 1. The outer wall of the first side plate 3 presses against the first limiting tooth 9, and the outer wall of the second side plate 4 presses against the second limiting tooth 11, until the battery box 2 falls to the bottom of the receiving cavity 1. The limiting plane 8 of the first side plate 3 enters below the first limiting tooth 9 and cooperates with the first limiting tooth 9 to limit the position. The top edge of the second side plate 4 enters below the second limiting tooth 11 and cooperates with the second limiting tooth 11 to limit the position.

[0053] In this embodiment, the copper electrode 6 has good wear resistance for high-frequency battery handling and placement, and maintains stable position during battery handling, which can reduce the occurrence of poor battery contact and improve the service life of the telemetry ECG monitor.

[0055] This embodiment provides a battery box for a telemetry ECG monitor, including a receiving cavity 1 located on the back of the telemetry ECG monitor and a battery box 2 disposed within the receiving cavity 1. The battery box 2 includes a pair of first side plates 3 arranged laterally opposite each other and a pair of second side plates 4 arranged longitudinally opposite each other. In this embodiment, "lateral" refers to the length direction of the battery. Figure 2 The left and right directions are the same, and the vertical direction is the battery arrangement direction. Figure 2 From top to bottom.

[0056] like Figure 7As shown, in this embodiment, except that the mating part is the slot 10 formed on the top of the first side plate 3, and the slot 10 extends laterally outward to the outer wall of the first side plate 3, everything else is the same as in embodiment 1. The first limiting tooth 9 extends into the slot 10 and is limited in the horizontal direction by the inner edge of the slot 10. At this time, the battery box 2 is also restricted in the horizontal direction within the receiving cavity 1, making the connection between the two more stable.

[0057] The installation process of the copper electrode 6 of this utility model is as follows: First, the copper sheet is bent into an inverted U-shaped copper electrode 6, keeping the two arms in contact or close together; the inner arm of the copper electrode 6 is aligned with the electrode groove 5 and inserted downwards into the first side plate 3. The thickness of the first side plate 3 is used to spread the two arms of the copper electrode 6, thereby ensuring that the copper electrode 6 is firmly clamped on the first side plate 3, and the end of the inner arm of the copper electrode 6 is flush with the bottom of the electrode groove 5. The lower end of the outer arm of the copper electrode 6 is soldered to the connection circuit 12 on the outer wall of the battery box 2. Then, a whole piece of insulating tape 13 is used to stick the three copper electrodes 6 to the outer wall of the first side plate 3. Finally, the battery box 2 containing the copper electrode 6 is placed face down into the receiving cavity 1. The outer wall of the first side plate 3 presses against the first limiting tooth 9, and the outer wall of the second side plate 4 presses against the second limiting tooth 11, until the battery box 2 falls to the bottom of the receiving cavity 1. The slot 10 of the first side plate 3 enters below the first limiting tooth 9 and cooperates with the first limiting tooth 9 to limit the position. The top edge of the second side plate 4 enters below the second limiting tooth 11 and cooperates with the second limiting tooth 11 to limit the position.

Figure 2 From top to bottom.

[0060] like Figure 8-9 As shown, in this embodiment, except for the outer wall grooves 7 on the outer wall of the first side plate 3 corresponding to the electrode grooves 5, everything else is the same as in embodiment 1. Each outer wall groove 7 extends upward to the top of the first side plate 3, and the outermost arm of the inverted U-shaped arms of the copper electrode 6 enters the outer wall groove 7 downward.
