Description

Lead device for neonate electrocardiogram positioning

Technical Field

The utility model relates to the field of medical equipment, in particular to a lead device for neonate's heart electrograph location.

Background

The normal heart activation originates from the sinoatrial node, and when exciting the atrium, the activation is conducted along the internodal tract-atrioventricular node-his bundle-left and right bundle branch-purkinje fibers in sequence, and finally exciting the ventricle. This sequential electrical propagation causes a series of potential changes, which form the corresponding band on the electrocardiogram.

Conventional PICC catheter tip positioning uses X-rays for positioning, however, identification of the catheter tip by X-rays may be inaccurate and adversely affect the X-rays of the neonate. The existing advanced neonatal electrocardiogram PICC catheter tip positioning is a guide-wire-free catheter technology, a heparin cap is connected through positioning, a 10ml syringe sucks normal saline and then is connected with the heparin cap, a needle stem is exposed 2/3, the normal saline is continuously and slowly injected, at the moment, limb leads are connected, a right upper limb lead is connected with the exposed needle stem, the normal saline is injected at the joint to ensure good conductivity, and then electrocardiogram information is acquired. If the wave form can not be drawn out in the operation of medical personnel, whether smooth need in time to inspect the conduction, still need in addition with steel needle point end perpendicular to heparin cap, can not avoid influencing the conduction with the pipe wall contact. After the lead connection is established, the electrocardiogram is not suitable to be observed and recorded during the operation of the catheter, because the movement of the catheter can influence the stability of the lead, the time for delivering the catheter is short, the accurate data of the electrocardiogram waveform can not be obtained, when the catheter enters the vena cava, the catheter is slowly delivered, and the catheter stops, the stability of the lead is checked, and the stable and reliable electrocardiogram waveform is observed and recorded. However, the specificity of the newborn baby, the small caliber of the catheter and more operation steps are needed, and the normal leading-out of the electrocardiogram becomes an important factor restricting the popularization of the electrocardiogram.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides a device that leads for neonate's heart electrograph location, its characterized in that includes the PICC pipe, the head end of PICC pipe stretch into the limbs of neonate and lead, the terminal branching of PICC pipe become two connecting pipes, one of them the connecting pipe on be provided with hollow metal connecting pipe, metal connecting pipe's end be used for connecting the syringe, metal connecting pipe's perisporium is used for pressing from both sides the centre gripping with the connection of electrocardiograph and is connected.

The utility model discloses a theory of operation: when medical personnel operated, stretch into neonate's limbs with PICC tube head end and lead and fix, then press from both sides the connecting clip of electrocardiograph on metal connecting pipe, insert the metal connecting intraductal fixed with the cylinder nipple at last, it is intraductal to promote the piston rod in the cylinder to push physiological saline and inject into PICC, appearance wave form on the monitor can. The X-ray imaging device has the advantages that the X-ray imaging is avoided, the exposure of X-rays is reduced, the steps and time for positioning the tip of the existing PICC catheter are greatly reduced, the operation is simple, the cost for positioning the heparin cap and the needle head is saved, and the occupational exposure is avoided.

In the above-mentioned lead device for positioning electrocardiogram of newborn, the connecting tube is further provided with a one-way valve for preventing physiological saline from flowing back into the syringe.

In the above-mentioned lead device for neonatal electrocardiographic positioning, the outer circumference of the metal connecting tube is 4-5 mm.

In the above-mentioned lead device for neonatal electrocardiographic positioning, the metal connecting tube is made of stainless steel.

In the above-mentioned lead device for electrocardiographic positioning of neonates, the other connecting tube is connected with a positive pressure connector or a heparin cap.

In the above-mentioned lead device for neonatal electrocardiographic positioning, the metal connecting tube is red in color.

In the above-mentioned lead device for neonatal electrocardiographic positioning, the front end of the metal connecting tube extends into the connecting tube.

The utility model has the advantages that: the utility model discloses compare prior art, the various steps that have significantly reduced influence the various interference that the wave form was drawn forth with the reduction, it is convenient safety more to draw the wave form operation, can carry out catheter tip location in real time in the PICC use and need not to promote the cylinder and pour into normal saline into again like the heparin cap of repeatedly opening like the single-end pipe, the extra wire rod of syringe needle and centre gripping syringe needle connection heart electrograph derivation clamp has been saved simultaneously, the heart electrograph data of production is also more stable, can also foresee tip direction, avoid complication to take place, the operation is safe, avoid occupation to expose, it can avoid the infant to expose because of the required X piece of shooting of catheter factor to compare traditional X light location, it exposes to reduce.
