Abstract
Description
Technical Field
[0001] The present application relates to the technical field of medical equipment accessories, and specifically to a lead wire connection structure for an electrocardiograph and an electrocardiograph monitor. Background Art
[0002] Although both an electrocardiograph and an ECG monitor are used to monitor the electrical activity of the heart, their usage scenarios and purposes are different, which leads to differences in the connection structure of their lead wires. The lead wires of an electrocardiograph are usually 10-pin plugs, and there are also 10 branch wires of the lead wires of an electrocardiograph, while ECG monitors usually use 3-pin or 5-pin plugs, and there are also 3 or 5 branch wires of the lead wires of an ECG monitor.
[0003] However, in certain emergency situations, such as in the emergency room or ambulance, it may be necessary to use an electrocardiograph for rapid diagnosis and transmit the results in real time to an electrocardiograph monitor for continuous monitoring. In this case, due to the different connection structures of the lead wires of the electrocardiograph and the electrocardiograph monitor, the lead wires of the two different devices cannot be used interchangeably. Therefore, one end of the lead wire of the electrocardiograph needs to be connected to the electrocardiograph first, and the other end needs to be connected to the patient's body through a negative pressure ball or a limb clamp. After the test is completed, the negative pressure ball or the limb clamp is removed from the patient, and then one end of the lead wire of the electrocardiograph monitor is connected to the electrocardiograph monitor, and then the electrode at the other end is connected to the patient. This increases the complexity of the operation process of medical staff in emergency situations. At the same time, switching back and forth between two different lead wires also increases the workload of medical staff. Utility Model Content
[0004] The purpose of this application is to provide a lead wire connection structure for an electrocardiograph and an electrocardiograph monitor to solve the technical problems raised in the above-mentioned background technology.
[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a lead wire connection structure for an electrocardiograph and an electrocardiograph monitor, comprising a lead wire main line, a connector and a connector respectively connected to the two ends of the lead wire main line, and a lead wire branch line connected to the other side of the connector, a conversion head is provided at the upper and lower ends of the connector, a pin 1 is provided on one side of the connector, a socket 1 matching the pin 1 is provided on one side of the conversion head, and a pin 2 is provided on the other side of the conversion head, and straps for fixing the conversion head on the connector are connected to both sides of the connector, and the two straps are adhered by Velcro.
[0006] In one embodiment, the upper end and the lower end of the connector are integrally formed with limiting flanges for limiting the position of the conversion head.
[0007] In one of the embodiments, a movable groove is provided inside the connecting head, and a limiting block is slidably connected in the movable groove. One end of the limiting block passes through the connecting head and extends outward, and an inclined surface is provided at the extended end of the limiting block. A spring is also provided in the movable groove, and the two ends of the spring are respectively connected to the inner wall of the movable groove and one side of the limiting block.
[0008] In one embodiment, the other end of the lead wire branch is fixedly connected to an electrode column, and a sliding sleeve is slidably sleeved on the outer surface of the lead wire branch, a traction wire is fixedly connected to one side of the sliding sleeve, and one end of the traction wire is fixedly connected to a sleeve body, a second socket for accommodating the electrode column is opened inside the sleeve body, and an electrode sheet is fixedly connected to the bottom of the sleeve body.
[0009] In one embodiment, a fixing sleeve is fixedly connected to the outer surface of the lead wire branch, and one end of the traction wire movably passes through the fixing sleeve and is connected to the sleeve body.
[0010] Compared with the prior art, the beneficial effects of this application are:
[0011] The present application provides a conversion head on the connector, which can convert the 10-pin connector into a 5-pin connector. In this way, when the lead wire needs to be connected to the electrocardiograph, the connector can be used to directly connect to the electrocardiograph, and all 10 lead wire branches can be used. When the lead wire needs to be connected to the electrocardiograph monitor, the conversion head on the connector is removed, and pin one is inserted into jack one of the conversion head to achieve 10-pin to 5-pin conversion, and then pin two on the conversion head is connected to the electrocardiograph monitor. At this time, only 5 of the 10 lead wire branches can be used. This design can be used in certain emergency situations, such as in the emergency room or ambulance, where an electrocardiograph may need to be used for rapid diagnosis, and the results can be transmitted to the electrocardiograph in real time for continuous monitoring. In this case, by connecting the electrocardiograph lead wire to the electrocardiograph monitor, a combination of rapid diagnosis and continuous monitoring can be achieved.

DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0020] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.
[0021] Example:
[0022] See also Figure 1-6 The present application provides a technical solution: a lead wire connection structure for an electrocardiograph and an electrocardiograph monitor, comprising a lead wire main line 1, a connector 2 and a connector 3 respectively connected to both ends of the lead wire main line 1, and a lead wire branch line 4 connected to the other side of the connector 3, wherein a conversion head 6 is provided at the upper and lower ends of the connector 3, a pin 1 34 is provided on one side of the connector 3, a socket 1 61 matching the pin 1 34 is provided on one side of the conversion head 6, and a pin 2 62 is provided on the other side of the conversion head 6, and straps 32 for fixing the conversion head 6 on the connector 3 are connected to both sides of the connector 3, and the two straps 32 are adhered by Velcro.
[0023] By setting the above scheme, when the lead wire main line 1 needs to be connected to the electrocardiograph, the connector 3 can be directly connected to the electrocardiograph, and all 10 lead wire branches 4 can be used. When the lead wire main line 1 needs to be connected to the electrocardiograph, the conversion head 6 on the connector 3 is removed, and the pin 34 is inserted into the jack 61 of the conversion head 6 to realize 10pin to 5pin (such as Figure 5 As shown, the five pins 2 62 on one side of the conversion head 6 are connected to five of the pins 1 34 through the five wires inside), and then the pin 2 62 on the conversion head 6 is connected to the ECG monitor. Correspondingly, only five of the ten lead wire branches 4 can be used. This design can be used in some emergency situations, such as in an emergency room or an ambulance, where an ECG machine may be needed for rapid diagnosis, and the results can be transmitted to the ECG monitor in real time for continuous monitoring. In this case, one end of the lead wire is unplugged from the ECG machine, and then the conversion head 6 is installed and inserted into the ECG monitor. Five of the ten lead wire branches 4 at the other end are removed from the patient and then adjusted in position. In this way, the connection with the ECG machine and the ECG monitor can be achieved through a lead wire connection structure, and a combination of rapid diagnosis and continuous monitoring can be achieved.
[0024] See also Figure 2 In this embodiment, the upper and lower ends of the connector 3 are integrally formed with limiting flanges 31 for limiting the conversion head 6 , and the limiting flanges 31 can prevent the conversion head 6 from moving on one side of the connector 3 .
[0025] See also Figure 3 In this embodiment, a movable groove 35 is further provided inside the connector 3, and a limiting block 33 is slidably connected inside the movable groove 35. One end of the limiting block 33 passes through the connector 3 and extends outward, and an inclined surface 37 is provided at the extending end of the limiting block 33. A spring 36 is also provided inside the movable groove 35, and the two ends of the spring 36 are respectively connected to the inner wall of the movable groove 35 and one side of the limiting block 33. When the conversion head 6 slides on one side of the connector 3, the conversion head 6 moves in the direction of the guide line main line 1, and the limiting block 33 can be pressed into the movable groove 35. When the conversion head 6 moves between the multiple limiting flanges 31, the conversion head 6 is separated from the limiting block 33, and the spring 36 pushes the limiting block 33 out of the movable groove 35. The limiting block 33 limits the conversion head 6. This design makes it convenient to insert the conversion head 6 between the two straps 32 without adjusting the strap 32.
[0026] See also Figure 4 and Figure 6In this embodiment, the other end of the lead wire branch 4 is fixedly connected to an electrode column 5, and the electrode column 5 is for convenient connection with the negative pressure ball and the limb frame, which are usually used for electrocardiograph detection, and a sliding sleeve 7 is slidably sleeved on the outer surface of the lead wire branch 4, a traction wire 9 is fixedly connected to one side of the sliding sleeve 7, and a sleeve body 10 is fixedly connected to one end of the traction wire 9, and a socket 11 for accommodating the electrode column 5 is opened inside the sleeve body 10, and an electrode sheet 12 is fixedly connected to the bottom of the sleeve body 10. A fixing sleeve 8 is also fixedly connected to the outer surface of the lead wire branch 4, and one end of the traction wire 9 movably passes through the fixing sleeve 8 and is connected to the sleeve body 10. When the lead wire is connected to the ECG monitor, 5 of the lead wire branches 4 and 5 electrode posts 5 cannot be used, so the traction wires 9 on the other 5 lead wire branches 4 are pulled to move the sleeve body 10 to the position of the electrode post 5, and the sleeve body 10 is put on the outside of the electrode post 5 through the second socket 11, so that the electrode post 5 can be connected to the electrode sheet 12 at the bottom of the sleeve body 10, and ECG monitoring is realized by attaching the electrode sheet 12 to the patient's body. It should be noted here that since the detection position of the electrocardiograph and the detection position of the ECG monitor are different, the positions of the 5 electrode sheets 12 need to be adjusted according to actual conditions.
