Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrocardiogram (ECG) examination, and in particular to an ECG measuring bed. Background Technology
[0002] Electrocardiographs (ECGs) record the physiological electrical signals generated during cardiac activity through lead structures, enabling the measurement and diagnosis of abnormal cardiac rhythms. However, in commonly used ECG machines, the leads are often tangled due to their close proximity. Without untangling the leads, they become difficult to distinguish, leading to inaccurate connections to different parts of the patient's body. Furthermore, the leads are of uniform length, and failure to untangle them can result in insufficient lead length. Therefore, the leads usually need to be tidied after the examination, which slows down the testing process. Utility Model Content
[0003] Therefore, the purpose of this utility model is to provide an electrocardiogram measuring bed, which has the advantages of convenient operation and simple structure.
[0004] An electrocardiogram (ECG) measuring bed, comprising:
[0005] Mattress;
[0006] A bedspread is placed on the top surface of the mattress, with the edges of the bedspread tapering to the bottom surface of the mattress. The edges have two first grooves extending in a first direction, and a perforation is formed at the end of the first grooves. The first grooves are interconnected through a second groove.
[0007] The lead assembly includes two foot lead wires and foot lead electrodes. The foot lead wires include a guide section, an adjustment section, and a connecting section. The guide section is connected to the electrocardiograph. The adjustment section is respectively inserted into the first wire groove, with its front end extending out of the bed cover and detachably connected to the guide section. Its end extends through the second wire groove and out through a hole in another first wire groove. One end of the connecting section is detachably connected to the adjustment section, and the other end is connected to the foot lead electrodes.
[0008] The electrocardiogram (ECG) measuring bed described in this invention features detachable foot leads, allowing the lead length to be adjusted according to the patient's height. Furthermore, the bed cover guides the leads, enabling them to be neatly concealed within the cover and preventing tangling. Simultaneously, by pulling the leads, the narrowing of the bed cover's edge at the mattress bottom can be adjusted, thereby increasing the length of the leads extending beyond the cover and expanding the adjustable range of lead length.
[0009] Furthermore, the lead assembly also includes pins and pin holders, both made of conductive material. The pins include a first pin and a second pin. The first pin is disposed on the guide section, and the second pin is disposed at the end of the adjustment section. There are two pin holders, respectively disposed at the front end of the adjustment section and on the connecting section. Each pin holder can be electrically connected to the first and second pins through a plug-in connection. This structure allows for quick assembly and disassembly of the lead assembly, improving operational convenience.
[0010] Furthermore, a limiting ring is provided at the end of the adjustment section, and the outer diameter of the limiting ring is larger than the diameter of the perforation. This structure prevents the connection point from retracting into the bed cover, facilitating operation by medical staff.
[0011] Furthermore, the mattress has a groove at the bottom, and an adjusting tube passes through the second groove. Both foot guide wires pass through the adjusting tube, which slides within the groove. This structure guides and limits the guide wires, and simultaneously ensures stable force on the back of the mattress when the foot guide wires are pulled, reducing friction between the guide wires and the mattress cover, thereby facilitating the gathering of the mattress cover edges.
[0012] Furthermore, the regulating tube has a tapered structure with openings at both ends that narrow towards the middle. This structure can prevent the lead wires from bending at both ends of the regulating tube and extend their service life.
[0013] Furthermore, the adjustment tube is connected to the back of the mattress via an elastic element. This structure allows the adjustment tube to quickly reset, enabling the edges of the mattress cover to automatically open after use, and allowing excess foot guide cables to retract into the mattress cover, preventing tangling and enabling quick storage.
[0014] Furthermore, a support frame is provided within the slide. This structure supports the mattress, preventing it from collapsing and causing discomfort to the patient.
[0015] Furthermore, the support frame is provided with a guide rail extending along the first direction, and the adjusting tube is provided with a slider, which is slidably connected to the guide rail. This structure can guide the adjusting tube to ensure that the mattress cover remains taut outside the mattress when it is narrowed, preventing the mattress cover from slipping off.
[0016] Furthermore, the bedspread also includes a sleeve that fits the mattress, with a cavity formed within the sleeve that houses the front side of the mattress. This structure secures the bedspread to the mattress, further preventing the bedspread from slipping off.
[0017] Furthermore, the lead assembly also includes a chest lead wire, chest lead electrodes, a hand lead wire, and a hand lead electrode. The chest lead electrodes are connected to the electrocardiograph via the chest lead wire, and one end of the hand lead wire is connected to the electrocardiograph, while the other end is connected to the hand lead electrode. This structure enables electrocardiogram measurements to be performed on other body parts.
[0018] To better understand and implement this invention, the following detailed description is provided in conjunction with the accompanying drawings. Attached Figure Description

[0025] To facilitate rapid examination and prevent leads from tangling, operators place the electrodes according to their position on the chest and limbs for easy identification and organization. However, this arrangement can result in insufficient lead length in the feet. Furthermore, due to significant differences in patient height and body type, the required lead length varies, and excessively long leads can cause inconvenience during operation and storage, and may even trip the patient.
[0026] Please see Figure 1-5 , Figure 1 This is a schematic diagram of the overall structure of the electrocardiogram measuring bed described in this utility model; Figure 2 This is a schematic diagram showing the layout of the lead wires in the bed cover; Figure 3This is a cross-sectional view of the electrocardiogram measuring bed described in this utility model; Figure 4 for Figure 3 A magnified view of a portion of region A in the middle; Figure 5 This is a schematic diagram of the foot lead wire structure.
[0027] This utility model discloses an electrocardiogram (ECG) measurement bed, including a mattress 1, a cover 2, and a lead assembly. During ECG measurement, the patient can lie on the mattress 1 to improve comfort and obtain a stable ECG. The shape, size, and softness of the mattress 1 can be selected according to actual needs. The cover 2 is placed on the mattress 1 and is made of a replaceable disposable plastic film or repeatedly washable fabric to ensure cleanliness and prevent cross-contamination. The lead assembly is a structure that conforms to the human skin to acquire electrical signals and transmits these signals to the ECG machine to form an ECG.
[0028] The bottom of the mattress 1 has a sliding groove, in which a support frame 11 can be installed to lift the part of the mattress 1 that corresponds to the sliding groove, so that the top surface of the mattress 1 remains flat and avoids causing discomfort to the patient.
[0029] The mattress cover 2 is fitted over the mattress 1, and its size should be larger than the mattress 1 to allow for some flexibility in terms of shrinkage relative to the mattress 1. A sleeve 21 is provided on the front side of the mattress cover 2, and this sleeve 21 forms an internal cavity that fits the front side of the mattress 1, thereby securing the mattress cover 2 and the mattress 1 together and preventing the mattress cover 2 from shifting or slipping off when the connecting wires are pulled. The cover surface of the mattress cover 2 covers the top surface of the mattress 1, and its left, right, and rear edges are gathered to the bottom surface of the mattress 1. A first groove 22 extending in a first direction is provided on each of the left and right edges, and a through hole 23 is formed at the end of the first groove 22. This first direction is the direction of the patient's height when lying down. The first grooves 22 are interconnected through a second groove 24, which is preferably located near the rear side of the mattress 1.
[0030] An adjusting tube 25 is threaded through the second groove 24, and both foot guide wires 31 are threaded through the adjusting tube 25. The adjusting tube 25 slides within the groove range. To guide and limit the sliding direction of the adjusting tube 25, a guide rail 111 extending along the first direction is provided on the support frame 11. A slider 251 is provided on the adjusting tube 25, and the slider 251 is slidably connected to the guide rail 111. To prevent damage to the wires threaded through it due to excessive bending, the two ends of the adjusting tube 25 are tapered structures that open from the ends to the middle, and a rounded transition is used. To achieve automatic reset of the adjusting tube 25, the adjusting tube 25 is connected to the rear side of the mattress 1 through an elastic element 252. The elastic element 252 can be a spring or other structure, which can be pulled to reset the adjusting tube 25 after inspection.
[0031] The lead assembly includes two foot leads 31 and foot lead electrodes 32, several chest leads and chest lead electrodes (not shown), and two hand leads 33 and hand lead electrodes 34. The foot leads 31 include a guide section 311, an adjustment section 312, and a connecting section 313. The guide section 311 connects to the electrocardiograph. The adjustment section 312 is inserted into the first groove 22, with its front end extending out of the mattress cover 2 and detachably connected to the guide section 311. Its end extends through the second groove 24 and out through a perforation 23 in another first groove 22. To prevent the adjustment section 312 from retracting into the bottom of the mattress 1, a limiting ring 314 is provided at the end of the adjustment section 312. The outer diameter of the limiting ring 314 is larger than the diameter of the perforation 23. One end of the connecting section 313 is detachably connected to the adjustment section 312, and the other end is connected to the foot lead electrodes 32.
[0032] The detachable connection can have various structural forms. In this embodiment, the lead assembly also includes pins and pin holders 36, both made of conductive materials. The pins can be terminals or readily available materials such as metal nails, thereby reducing costs. The pins include a first pin 351 and a second pin 352. The first pin 351 is disposed on the guide section 311, and the second pin 352 is disposed at the end of the adjustment section 312. There are two pin holders 36, which are respectively disposed on the front end of the adjustment section 312 and the connecting section 313. Both pin holders 36 can be electrically connected to the first pin 351 and the second pin 352 by plugging them in.
[0033] The chest lead electrode is connected to the electrocardiograph via the chest lead wire. One end of the hand lead wire 33 is connected to the electrocardiograph, and the other end is connected to the hand lead electrode 34. This structure is a standard technical method in the industry and will not be described in detail here. To allow for adjustment of the length of the chest lead wire and the hand lead wire 33, a detachable structure, such as that of the foot lead wire 31, can also be adopted.
[0034] When in use, the hand leads can be placed on the left and right sides of the front of the mattress, corresponding to the hand positions of patients of normal height, and the foot leads can be placed on the left and right sides of the back of the mattress, corresponding to the foot positions of patients of normal height. This makes the overall structure clear at a glance and reduces the time that medical staff spend distinguishing between the hand and foot leads.
[0035] When the patient is short, the connecting segment can be directly connected to the guiding segment, significantly reducing the length of the lead wire. When the patient is tall, the foot lead electrode can be pulled, causing the adjusting segment inside the mattress to straighten from a curved position. This brings the left and right edges of the mattress towards the center, and the rear edge of the mattress is pulled forward by the adjusting tube. This reduces the length of the adjusting segment within the mattress while increasing the length extending beyond it, allowing the foot lead electrode to fit snugly against the patient's foot. Upon completion of the measurement, the foot lead electrode is released, and the elastic element pulls the adjusting tube, returning the adjusting segment from a near-straight position to a curved one. The portion of the adjusting segment extending beyond the mattress retracts until the limiting ring abuts against the mattress, achieving automatic lead wire retraction.
[0036] The electrocardiogram (ECG) measuring bed described in this invention features detachable foot leads, allowing the lead length to be adjusted according to the patient's height. Furthermore, the bed cover guides the leads, enabling them to be neatly concealed within the cover and preventing tangling. Simultaneously, by pulling the leads, the narrowing of the bed cover's edge at the mattress bottom can be adjusted, thereby increasing the length of the leads extending beyond the cover and expanding the adjustable range of lead length.
