Embodiment Construction

[0028] For the purposes of this patent application, the following terms shall be taken to have the following meanings.

[0029] A power supply unit means an individual unit capable of charging with electrical energy and storing electrical energy.

[0030] The battery pack is the actual battery inside the power supply unit.

[0031] The welding unit is a unit powered by the power supply unit and capable of performing welding operations.

[0032] In general, the disclosure herein is directed to electrical welding equipment using a DC power source with electrical energy stored in a battery pack.

[0033] Figure 1 illustrates a prior art device of this type. The device shown is a welding device with a welding unit 1 attached to a battery pack 3 via an electric cord 2 .

[0034] Although this is a versatile device, it can have some disadvantages: it is not so easy to move since it is somewhat bulky.

[0035] Therefore, a more general arrangement is shown in Figure 2 (JPH0610662...

Abstract

This disclosure relates to a cordless, hand held and electrically powered apparatus, comprising a welding unit (12), a power unit (4) for powering the welding unit, wherein the power unit is connectable directly to and disconnectable from the welding unit via an interface. The power unit is provided with a push button (16) that is configured to energize the welding unit when pressed down, thus initiating operation thereof. The advantage is that the apparatus can be made more compact, and thereby ease of handling is improved. Preferably, the welding unit and the power unit each comprise circuitry (17a, 17b) configured to exchange information when mounted together via the interface. The information is usable for a determination whether the power unit is a correct one or not.

Description

[0001] The present disclosure relates generally to powered devices, and in particular to devices with connectable / disconnectable power supply units / batteries. More specifically, it relates to plastic welding equipment. Background technique [0002] Welding techniques (ultrasonic or RF) are often used when sealing different containers designed to contain blood, such as blood bags. One such product (C5546Qseal-handy) is offered by Conroy Medical and is shown in FIG. 1 . It comprises a battery pack 2 (ie a DC power supply), a device 1 for welding (which is usually hand-held) and an electrical cord / cable 3 for connecting the battery pack to the hand-held device. The device can also be powered by an AC power source via a suitable cord. Qseal-handy is a fully automated system for sealing PVC and EVA tubing connected to blood bags included in blood bags or in Apheresis disposable kits. This sealing can be performed while the donor is still attached to the blood bag or apheresis di...
