Technical Field

The invention belongs to the technical field of sealing equipment, and particularly relates to a PVC (polyvinyl chloride) conduit sealing device.

Background

Medical devices refer to instruments, devices, apparatuses, in-vitro diagnostic reagents and calibrators, materials and other similar or related items used directly or indirectly in the human body, including necessary computer software, and the effects are mainly obtained by physical means and the like, not by pharmacological, immunological or metabolic means, or are only assisted by the means. The sealing machine is a common medical apparatus and needs to seal medical catheters in the medical industry, but the traditional sealing machine utilizes an external high-temperature hot-melting catheter to seal, so that the operation is inconvenient, and the structure of the sealing machine is often complex.

Disclosure of Invention

In order to solve the above problems in the prior art, the present invention is directed to a PVC conduit sealing device.

The technical scheme adopted by the invention is as follows: a PVC conduit sealing device comprises a shell, wherein a thermode support with a shaft sleeve is fixedly connected to one side plate of the shell, a thermode is arranged in the shaft sleeve and is connected with a linear driving device arranged in the shell, a cold electrode support connected with the thermode support is arranged outside the shell, a cold electrode opposite to the thermode is arranged on the cold electrode support, and the thermode is connected with a high-frequency generator arranged in the shell; the shell is provided with length scale marks.

Furthermore, the linear driving device is an electromagnetic push rod, the electromagnetic push rod is arranged on an electromagnetic push rod support, and the electromagnetic push rod support is connected with the thermode support.

Furthermore, a slide rail is arranged on the thermode support, a slide block is arranged at the front end of an output shaft of the electromagnetic push rod, a slide groove matched with the slide rail is formed in the slide block, and the slide block is connected with the thermode through a connecting shaft.

Furthermore, the high-frequency generator is connected with a high-frequency filter, the high-frequency filter is connected with a high-frequency signal adapter, and the high-frequency signal adapter is connected with the hot electrode.

Furthermore, the high-frequency generator, the high-frequency filter and the high-frequency signal adapter are all arranged in the shielding box.

Furthermore, a switch power supply is arranged in the shell, the output end of the switch power supply is connected with the high-frequency generator, and the input end of the switch power supply is connected with the power filter; the shell is provided with a power input socket, and the power input socket is connected with a power filter.

Furthermore, the shell is provided with a flow guide hole, and a heat radiation fan is arranged in the shell.

Further, a handle is arranged at the top of the shell.

Furthermore, the shell is provided with a slot for installing the splash-proof piece, so that the splash-proof piece is detachably arranged right above the cold electrode.

Furthermore, the sealing machine is provided with a protective cover which covers the cold electrode support and the hot electrode.

The invention has the beneficial effects that: only the conduit is needed to be placed between the hot electrode and the cold electrode, and the conduit can generate high temperature due to the fact that internal molecules move violently under the polarization effect of high-frequency oscillation, so that the conduit is melted to form a seal, and the operation is convenient. And the position distance between the hot electrode and the cold electrode can be adjusted, and the catheters with different sizes can be sealed.
