Description
Technical Field
[0001] The utility model relates to the field of medical equipment, in particular to an electrocardiograph lead. Background Art
[0002] The electrocardiograph lead is a line used to connect the electrocardiograph host and the patient, and is used to collect weak electrical signals generated by human heart activity and transmit them to the electrocardiograph host. The existing electrocardiograph lead includes a lead wire, six chest connection structures and four limb connection structures. The lead wire includes six first branch wires and four second branch wires. The first branch wires are arranged one-to-one with the chest connection structures and are detachably connected. The second branch wires are arranged one-to-one with the limb connection structures and are detachably connected.
[0003] The chest connection structure is as follows Figure 1 The device includes a hemispherical adsorption structure, an elastic balloon and a connecting sleeve. When in use, the adsorption structure is attached to the chest of a human body, and the elastic balloon is squeezed and rebounds to absorb the air in the inner cavity of the adsorption structure, so that the adsorption structure is attached to the human body. The connecting sleeve is connected to the connector of the first branch line. The weak electrical signal generated by the human heart activity is transmitted to the main unit of the electrocardiograph through the adsorption structure and the lead wire.
[0004] Limb connection structure Figure 2 As shown, it is a clip form, with electrodes on the clip, and the clip is clamped on the limbs of the human body so that the electrodes fit the human body. The electrical signal is transmitted to the mainframe of the electrocardiograph through the electrodes on the clip and the lead wires.
[0005] During an electrocardiogram examination, after one patient is examined, the electrocardiogram leads are directly used for the next patient. In this way, the chest connection structure and the limb connection structure inevitably carry the germs on the patient's body. For patients with non-infectious diseases, this does not cause the risk of disease transmission. However, many diseases are contagious and can be transmitted through contact. If the chest connection structure and the limb connection structure carry the germs on the patient's body and are used for the next patient, it may cause disease transmission. Even if the electrocardiogram leads are disinfected, the existing chest connection structure and the limb connection structure are relatively complex, and the disinfection effect in a short time is often not ideal.

DETAILED DESCRIPTION
[0025] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.
[0026] like Figures 3 to 5As shown, the electrocardiograph lead comprises a lead wire 1, six chest connection structures 2 and four limb connection structures 3, the lead wire 1 comprises six first branch wires 11 and four second branch wires 12, the first branch wires 11 are arranged one-to-one with the chest connection structures 2 and are detachably connected, the second branch wires 12 are arranged one-to-one with the limb connection structures 3 and are detachably connected; the chest connection structure 2 comprises an adsorption structure 21 and a first connection sleeve 22, the adsorption structure 21 is hemispherical in shape, the first connection sleeve 22 is connected to the adsorption structure 21 and communicates with the inner cavity of the adsorption structure 21; the first branch wire 11 It includes a first wire 111, a first connector 112 and an elastic balloon 113. The front end of the first connector 112 is inserted into the first connecting sleeve 22 and tightly fits with the first connecting sleeve 22. The first connector 112 has an air hole 1121. The elastic balloon 113 is connected to the rear end of the first connector 112, and the first wire 111 is connected to the first connector 112. The adsorption structure 21 and the first connector 112 are both conductive, and the adsorption structure 21, the first connector 112 and the first wire 111 are conductive. The elastic balloon 113 is connected to the inner cavity of the adsorption structure 21 through the air hole 1121.
[0027] When the present invention is used, the chest connection structure 2 is sucked onto the patient's chest, and the attraction comes from the rebound of the elastic balloon 113 after being squeezed. The elastic balloon 113 rebounds after being squeezed and sucks the air into the inner cavity of the adsorption structure 21 through the air hole 1121, so that the adsorption structure 21 has suction force. The weak electrical signal generated by the human heart activity is transmitted through the adsorption structure 21, the first connector 112 and the first wire 111 and finally transmitted to the electrocardiograph body.
[0028] The utility model improves the chest connection structure 2 so that it no longer has the elastic balloon 113, and the 113 elastic balloon is set on the lead wire 1. In this way, the chest connection structure 2 is only composed of the adsorption structure 21 and the first connection sleeve 22. The structure is very simple and the volume is very small. It is easy to disinfect and it takes up very little space when equipped with multiple pieces. After the electrocardiogram of a patient is completed, the chest connection structure 2 can be removed and disinfected with alcohol or other disinfectants, and the disinfected chest connection structure 2 can be replaced. It can prevent the chest connection structure 2 contaminated with germs from contacting the next patient undergoing an electrocardiogram, thereby helping to prevent the spread of germs. When the patient does not suffer from an infectious disease, the chest connection structure 2 can also be used directly or sprayed with disinfectant without being removed and replaced.
[0029] The adsorption structure 21 and the first connector 112 are both required to be conductive and are made of metal, while the elastic balloon 113 can be made of elastic materials such as rubber. The front end of the first connector 112 is inserted into the first connecting sleeve 22 and fits tightly with the first connecting sleeve 22, so that the connection is achieved while also ensuring the seal between the two to avoid air leakage. The interference fit between the first connector 112 and the first connecting sleeve 22 should be small to ensure that the first connector 112 does not fall off easily and to avoid excessive resistance to pulling out the first connector 112. Specifically, the first connecting sleeve 22 is arranged at the center of the surface of the adsorption structure 21 along the radial direction of the adsorption structure 21.
[0030] The first wire 111 can be arranged outside the elastic balloon 113, but in order to make the first branch line 11 more concise and regular, it is preferred that the first wire 111 passes through the elastic balloon 113. Obviously, the elastic balloon 113 and the first wire 111 should be sealed. In order to prevent the first wire 111 from being pulled due to the deformation of the elastic balloon 113 due to squeezing and loosening, it is preferred that the first wire 111 located inside the elastic balloon 113 is curved.
[0031] The utility model should also avoid the limb connection structure 3 being used directly after contact with the patient, which may cause disease transmission. Figure 6 and Figure 7 As shown, the preferred limb connection structure 3 includes a U-shaped piece 31, a second connecting sleeve 32 and an elastic band 33, and the second connecting sleeve 32 is connected to either end of the U-shaped piece 31; the second branch line 12 includes a second wire 121 and a second connector 122, and the second connector 122 is inserted into the second connecting sleeve 32 and tightly fits with the second connecting sleeve 32; the U-shaped piece 31 and the second connecting sleeve 32 are both conductive, and the U-shaped piece 31, the second connecting sleeve 32, the second connector 122 and the second wire 121 are conductive; the elastic band 33 is used to fix the U-shaped piece 31 on the human limbs.
[0032] The elastic band 33 can be made of common elastic bandages in hospitals, and the two ends can be provided with adhesive to facilitate the connection of the two ends. The elastic band 33 is put on the patient's limbs and presses the U-shaped sheet 31 to fix the U-shaped sheet 31, and the elastic band 33 passes through the recess of the U-shaped sheet 31.
[0033] The utility model improves the limb connection structure 3, omits the clip, and the elastic band 33 has a very low cost and can be used once. The U-shaped piece 31 and the second connecting sleeve 32 are removed after a patient's electrocardiogram examination is completed, and disinfected with alcohol or other disinfectants, and the disinfected U-shaped piece 31 and the second connecting sleeve 32 are replaced. The U-shaped piece 31 and the second connecting sleeve 32 are also very simple in structure and small in size, which is convenient for disinfection and occupies very little space when equipped with multiple pieces, which is also conducive to avoiding the spread of germs. When the patient does not suffer from an infectious disease, the limb connection structure 3 may not be replaced, and can be directly continued to be used or sprayed with disinfectant. The U-shaped piece 31 and the second connecting sleeve 32 need to be able to conduct electricity and can be made of metal. Specifically, the second connecting sleeve 32 is preferably perpendicular to the bottom surface of the U-shaped piece 31.
[0034] The matching relationship between the second connector 122 and the second connector sleeve 32 can be the same as the matching relationship between the first connector 112 and the first connector sleeve 22. Since the second connector 122 and the second connector sleeve 32 do not need to be sealed, the second connector sleeve 32 can also have an axial slit 221. The function of the axial slit 221 is to allow the second connector sleeve 32 to deform slightly, which is more conducive to the second connector sleeve 32 clamping the second connector 122 by its elastic deformation. If the second connector sleeve 32 is too loose, it can be appropriately clamped with a signature.
