Cardiac diagnosis lead-lineTechnical field
The present invention relates to a kind of medicine equipment annex, and in particular to a kind of cardiac diagnosis lead-line, is particularly suitable for use in X-rayPatient monitoring under screening-mode.
Background technology
Electrocardiograph is usually used in detecting human heart physiological function running situation, and people is measured by chest leads and limb leadsThe potential difference at each position of body, thus obtained ecg wave form reflects the situation of human heart.
The electrocardiogram lead wire used at present includes shielded multiconductor cable, deconcentrator and branch's conducting wire, branch's conducting wireIncluding 2 upper limbs conducting wires, 6 chest leads lines and 2 inferior limb lead wires, shielded multiconductor cable is directly separated after deconcentratorGe Tiao branches conducting wire, the end of chest leads line is connected to the end of rubber bulb type electrode, upper limbs conducting wire and inferior limb lead wireEnd is connected to electrode holder.
In clinical position, cardiac monitoring is carried out to patient especially under X-ray screening-mode, due to existing leadLine is metallic article, and X-ray can not have an X-rayed, therefore, diagnosis can be interfered or cause erroneous judgement.
Therefore, a kind of cardiac diagnosis lead-line is designed, is particularly suitable for use under X-ray screening-mode and electrocardio prison is carried out to patientShield, can allow X-ray through perspective is realized, so as to ensure the accuracy of diagnosis, it is clear that with positive realistic meaning.
The content of the invention
The goal of the invention of the present invention is to provide a kind of cardiac diagnosis lead-line.
To achieve the above object of the invention, the technical solution adopted by the present invention is：A kind of cardiac diagnosis lead-line, it is hollow that it includes oneFlexible pipe, conduction liquid is marked with the flexible pipe, one end of the flexible pipe is provided with adsorption section, and the other end of the flexible pipe is provided with sealingPlug,
The adsorption section is connected with the cavity in flexible pipe.
Preferably, the flexible pipe is PVC plastic sebific duct, and the PVC plastic sebific duct is injection flexible pipe.
Further, the external diameter of the flexible pipe is 4.5~5mm, and internal diameter is 3.5~4mm.
For the external diameter of the flexible pipe, the present invention is not specifically limited, it is typical but non-limiting can be 4.5mm,4.6mm、4.7mm、4.8m、4.9mm、5mm.It is preferred that 4.7mm.
For the internal diameter of the flexible pipe, the present invention is not specifically limited, it is typical but non-limiting can be 3.5mm,3.6mm、3.7mm、3.8m、3.9mm、4mm.It is preferred that 3.7mm.
Preferably, the conduction liquid is 0.9% physiological saline.
Preferably, the adsorption section is infundibulate sucker.
Further, be additionally provided with an electrode in the adsorption section, the electrode be tightly connected with flexible pipe and with conduction liquid oneWith composition signal path.
Preferably, the electrode is graphite electrode.
Preferably, the sealing-plug is rubber stopper.
Further, a stainless steel probe is inserted with the sealing-plug, the external electrocardiograph of stainless steel probeP-wire, the p-wire is connected to the signal input part of electrocardiograph.
The present invention operation principle be：The present invention cardiac diagnosis lead-line when in use, by the adsorption section of conducting wire and human bodyExtruding contact, conducting wire can be closely pulled together by the negative pressure of adsorption section with human body, and now, conduction liquid connects with human bodyTouch, then will be contacted in the sealed plug insertion flexible pipe of the stainless steel probe of p-wire one end of electrocardiograph with conduction liquid, p-wireThe signal input part connection of the other end and electrocardiograph, so as to constitute a complete signal path, realizes event channel.
Because above-mentioned technical proposal is used, the present invention has following advantages compared with prior art：
1. the present invention has abandoned the structure of existing metal conducting wire, using flexible pipe as carrier, conduction liquid structure is injected in flexible pipeFixed into conducting wire, and by adsorption section with human body, realize signal conductor, electrocardio is carried out to patient under X-ray screening-modeDuring monitoring, X-ray can be allowed through perspective is realized, so as to ensure the accuracy of diagnosis；
2. the present invention is simple in construction, manufacturing cost is low, suitable for popularization and application.
