Background

The selection of the position of the built-in catheter in the PICC working process is crucial, the reasonable position of the built-in catheter can be more accurately selected by utilizing the method for collecting the intracavitary electrocardiosignals, the safety is improved, and the secondary injury to a patient is reduced. Special equipment with similar functions: the electrocardio-lead Doppler color ultrasonic all-in-one machine uses a special conductive catheter to confirm the position of a guide wire by collecting electrocardio signals in a cavity. However, such devices are expensive (25-40 ten thousand) and cannot be popularized, especially in urban hospitals of second and third grades, and after the clinical PICC is placed, the position of the tip of the catheter needs to be confirmed, and after the catheter is adjusted for the second time when the depth is too deep or too shallow, the patient needs to take a picture again, so that the patient can radiate X-ray for the second time.

The positioning work of the PICC catheter can be completed by adopting a common multi-parameter monitor, the connection mode of machine ends of lead wires is very different based on various kinds of monitors, and the model of the monitor has the orientation requirement in order to use a special lead wire to engage in the PICC work, so that the inconvenience is caused to the development of clinical work. And the cost of manufacturing a special lead wire for each type of monitor is high, and the utilization rate cannot be guaranteed. For example, chinese patent CN207323465 discloses a novel intracavitary electrocardiograph connection device, which discloses an intracavitary electrocardiograph connection device with simple operation, but the outer edge of the metal ring is not wrapped by insulating material, which is prone to poor conductivity after long-term use, and the intracavitary electrocardiograph connection device used in cooperation with the model of the monitor needs to be provided according to the different models of the monitors, so that the applicability is single and the cost is high.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem and providing a recoverable intracavitary electrocardio acquisition lead.

For realizing the above purpose of the utility model, the utility model provides a recoverable intracavity electrocardio is gathered and is led, press from both sides including electrocardio button male joint, wire and crocodile, be connected through the wire between electrocardio button male joint and the crocodile clamp.

The male connector of the electrocardio button of the electrocardio acquisition connecting device can be connected with the female connector of the electrocardio button of the electrocardio lead wire of almost all models of electrocardio monitors; the male connector of the electrocardio button is a convex button, the total height is 0.46 cm, and the height of the convex part is 0.2 cm.

The left end of the crocodile clip is connected with a guide wire, and the right end of the crocodile clip is connected with a metal tube of the PICC catheter; the size of the crocodile clip is smaller than 2 cm, and the crocodile clip is made of an antirust metal material with good conductivity and is applicable to various disinfection modes.

The material of the lead meets the requirements of ethylene oxide sterilization and disinfection.

The utility model has the advantages that: the volume is small, the disinfection is convenient, high-value equipment with similar functions can be replaced, and the cost is low; the selected material is a medical material special for clinic, and the safety is high; the design of the male connector of the ECG button connected with the ECG lead wire of the common monitor can be connected with the ECG leads of almost all brands of monitors, so that the selection of equipment is more flexible and the applicability is strong; less crocodile clamp is designed into with PICC pipe connection's one end, and is little to PICC pipe implantation influence, and is better with the interlock effect between the PICC pipe, and electric conductive property is excellent, is difficult for shifting.
