Abstract
Description
Technical Field
[0001] The utility model relates to the field of medical instruments, in particular to an improved neonatal limb lead and chest lead connector. Background Art
[0002] Limb leads include standard leads and pressurized unipolar limb leads. Standard leads are bipolar limb leads that reflect the change in potential difference between the two limbs. Pressurized unipolar limb leads are unipolar leads that basically represent the change in potential at the detection site.
[0003] The chest leads are unipolar leads, including V1 to V6. The positive electrode for testing should be placed at a fixed position on the chest wall, and each of the three electrodes of the limb leads should be connected in series with a 5ko resistor, and then the three are connected together to form a "dry electrode" or central terminal.
[0004] However, the existing limb leads are connected to the patient's limbs using metal clips, and most of them are of a single model, which is just suitable for adults or minors with larger bodies. However, for newborns, the size of the connection clip is still too large, which is not particularly convenient for clinical application. It cannot be well clamped on the limbs of newborns, and it is also impossible to accurately monitor the physical data of newborns.
[0005] In addition, the existing chest leads are adsorbed to the designated position of the body through a balloon with negative pressure adsorption, but their size is just suitable for adults or larger minors. For newborns, their size is still too large. Moreover, the skin of newborns is delicate, and the subcutaneous blood vessels and other tissues are not yet fully developed. The adsorption of the balloon can easily lead to blood stasis in that area, causing local damage. Utility Model Content
[0006] The purpose of the utility model is to provide an improved neonatal limb lead and chest lead connector, which can better adapt to the limb size of the neonate, can effectively connect the limbs to realize limb leads, and will not cause damage to the skin of the neonate during chest lead connection, thereby avoiding damage to local parts of the body.
[0007] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:
[0008] An improved neonatal limb lead and chest lead connector comprises a fixing component, on which a metal guide is provided. The metal guide is electrically connected to a metal clip via a connecting line and is connected to a connector of an electrocardiograph monitoring line via the metal clip.
[0009] Furthermore, the fixing component is a strip wristband, and two ends of the strip wristband are bonded by Velcro.
[0010] Furthermore, the fixing component is an electrode patch.
[0011] Furthermore, the electrode patch and the connecting wire are connected via a snap fastener.
[0012] Compared with the prior art, the beneficial effects of the present invention are:
[0013] This patent realizes limb leads by connecting the wristband to the newborn's limbs, which can perfectly adapt to the newborn's limb size, ensure that the metal guide used for monitoring fits the limbs completely, and ensure the comfort of the device after wearing. In addition, this patent uses electrode patches instead of traditional negative pressure balloons to realize chest leads, which can not only adapt to the newborn's torso size, but also avoid pain and damage to the newborn's skin caused by excessive negative pressure adsorption. It is more suitable for use in newborns, so as to better monitor the physical data of newborns. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Embodiment 1: An improved neonatal limb lead and chest lead connector, comprising a strip wristband 4, the two ends of which are bonded by Velcro, a metal guide 1 is provided on the strip wristband 4, the metal guide 1 is electrically connected to a metal clip 3 via a connecting line 2, and the metal clip 3 is connected to the connector of the electrocardiograph monitoring line to realize limb leads, which is better suitable for the body shape of newborns.
[0021] Embodiment 2: An improved neonatal limb lead and chest lead connector comprises an electrode patch 5, on which a metal conductor 1 is provided, and the metal conductor 1 is electrically connected to a metal clip 3 via a connecting line 2, and is connected to a connector of an electrocardiograph monitoring line via the metal clip 3. The electrode patch 5 is attached to the torso of the neonate via a conductive gel to realize chest lead connection, which can avoid damage to the neonate's skin caused by the traditional negative pressure adsorption connection method and avoid local damage to the neonate.
[0022] Embodiment 3: The difference from Embodiment 2 is that the electrode patch 5 and the connecting wire 2 are connected by means of a snap fastener, and the snap fastener is used instead of the metal clip 3, so that the connecting wire 2 and the electrode patch 5 are detachable, which is more flexible to use and has a wider range of applications.
[0023] This patent connects the wristband to the newborn's limbs to achieve limb leads, which can perfectly adapt to the newborn's limb size. This patent uses electrode patches instead of traditional negative pressure balloons to achieve chest leads, which can not only adapt to the newborn's torso size, but also avoid pain and damage to the newborn's skin caused by excessive negative pressure adsorption. It is more suitable for newborns, so as to better monitor the newborn's physical data.
