Device for fusing injection needle

Abstract

A device for fusing an injection needle in which the treatment cost can be reduced by prolonging the lifetime of electrode rollers. The device (1) for fusing an injection needle comprises a fusing mechanism section (10) including two electrode rollers (11, 12) which can be brought into contact with the injection needle (N) of a syringe (S), a rotation drive mechanism (13) for rotating the electrode rollers (11, 12), and a power application mechanism (19) for applying power between the electrode rollers (11, 12), a guide mechanism section (30) including a holding member (32) for holding the syringe (S) and a guide member (31) which engages with the holding member (32), guides it toward the electrode rollers (11, 12), and then brings the injection needle (N) of the syringe (S) into contact with the electrode rollers (11, 12), and a position adjusting section (40) for adjusting the relative positional relation between the fusing mechanism section (10) and the guide mechanism section (30) in the axial direction of the electrode rollers (11, 12) and shifting the position where the injection needle (N) of the syringe (S) is brought into contact with the electrode rollers (11, 12).

Description

technical field [0001] The invention relates to an injection needle fusing device, which is used for fusing and discarding the injection needles of used syringes. Background technique [0002] For the used syringe, if the worker who handles it accidentally touches the injection needle, it is likely to cause secondary infection. Therefore, in recent years, an injection needle fuse device for fusing and discarding the injection needle has been proposed as such an injection needle. As a fuse device, for example, a device disclosed in Japanese Patent Application Laid-Open No. 11-285531 is known. [0003] The injection needle fusing device is composed of a fusing mechanism for fusing the injection needle of the syringe, a guide mechanism arranged above the fusing mechanism, and guiding the injection needle to the fusing mechanism. [0004] The above-mentioned fusing mechanism includes: two paired electrode rollers arranged in parallel and horizontally at intervals and in contact...

Problems solved by technology

[0013] However, in order to make the current flow stably through the injection needle and prevent the above-mentioned melting loss and sticking, titanium, tungsten, and materials containing copper or silver (brass and phosphor bronze) with low resistance, high melting point, and high thermal conductivity are used. etc.) to form the electrode roller with a high-priced metal material such as an alloy, and in order to make the electrode roller contact with the electrical contact for energizing the electrode roller and improve the heat dissipation, it is formed as the injection needle fuse device of the above-mentioned prior art The structure in which the injection needle is extended in the axial direction so that the injection needle contacts the same position of the electrode roller can only use a part of the electrode roller, and the processing cost becomes high. In addition, the use efficiency of the electrode roller is reduced, so it is not preferable.

[0014] Furthermore, when the exchange efficiency of the electrode roller is high, the exchange time is required, and there is a problem that the treatment of the injection needle cannot be effectively performed.
