Self-locking chuck and electrode slice connecting device

Abstract

The invention provides a self-locking chuck and an electrode slice connecting device, and the self-locking chuck does not get loose, and is safe in treatment, good in electrical conductivity, low in cost and good in universality. The self-locking chuck comprises an upper cover, a lower cover and a turning plate; the upper cover and the lower cover are buckled and connected, a clamping channel is formed between the upper cover and the lower cover, a connecting shaft is fixedly arranged at the front end of the upper cover, a half open shaft sleeve is arranged in the eccentric position of the turning plate, a front protruding part and a rear protruding part are arranged at the lower part of the turning plate, the shaft sleeve is correspondingly arranged at the upper end of the rear protrudingpart, the connecting shaft is sleeved with the turning plate through the shaft sleeve, a metal elastic sheet is arranged in the clamping channel, the lower end face of the metal elastic sheet is abutted against the lower cover, the upper end face of the metal elastic sheet is abutted against the rear protruding part and the upper cover respectively, and a wire extending outwards is arranged on the rear part of the metal elastic sheet. The electrode slice connecting device comprises an electrode slice and the self-locking chuck; the electrode slice comprises an electric conduction main body, atransition section and an extending end; the extending end is connected with the electric conduction main body through the transition section, and the front end of the transition section and the extending end are arranged in the clamping channel.

Description

technical field [0001] The invention relates to the technical field of physiotherapy electrodes, in particular to a self-locking chuck and an electrode sheet connection device. Background technique [0002] Nerve and muscle stimulator therapy has become a more commonly used physical therapy method in clinical practice, and various low-frequency and intermediate-frequency therapeutic equipment have developed rapidly. This type of physical therapy requires the use of physiotherapy electrodes. The traditional general-purpose physical therapy electrodes and the electrical connection of the therapeutic device mainly adopt three forms: [0003] The first type, jack type, as shown in Figure 1(a), is provided with a conductive jack on the physiotherapy electrode sheet, which is commonly used in electrode sheets made of silicone rubber. [0004] The second type, lead-out type, as shown in Figure 1(b), embeds wires in the interlayer of the electrode sheet and sets a conductive jack a...

AI Technical Summary

Problems solved by technology

[0006] There are several common problems in the connection methods of these three electrode sheets: 1. The cost is high, and there are special conductive interfaces in the structure, so that the electrode sheets are made of many kinds of materials, the production process is complicated, and the production cost is high; 2. Poor contact is easy, due to the contamination and wear and aging problems of the conductive jack and the conductive snap button, it is easy to cause poor contact of the electrode sheet and affect the use; 3. It is easy to loosen and affect the safety of treatment, and the normal separation from the electrode sheet depends on external force Stretch, if you encounter unexpected pull during treatment (such as patient position movement, etc.), it is prone to accidental loosening, causing a sudden change in current and thus affecting the safety of treatment; 4. Accidental contact of metal parts, traditional interface methods cannot avoid metal The plug or metal snap button accidentally touches the human body, causing an accidental electric shock to the human body; 5. The universal type is not good, and the conductive interface forms and specifications of the connecting device are different, and they are not compatible with each other, which makes the versatility of the physiotherapy electrode sheet poor.
