Abstract

PURPOSE:To suitably convey contained objects, by using a rubber tube oxidized with the surface and promptly restoring crushing, caused in an internal peripheral wall of the tube through contact between the tube and rollers, as a contact point moves. CONSTITUTION:Peracid, potash chromic acid, etc. of, for instance, perhalogen acid of perchloric acid or the like, hydrogen peroxide, peracetic acid, perbenzoic acid or the like are used for an oxidizing agent of oxidation treatment, and for instance, the methods, in which a silicon tube is immersed for a fixed time at certain temperature in a solution dissolving the oxidizing agent, are provided for the oxidation treatment. Such a tube 1 of a ''Peristaltic '' pump applied with the oxidation treatment is operated such that an internal peripheral surface of the tube 1, even if crushed by a roller 2 is removed the crushing in an internal peripheral wall of the tube 1 as a contact point of the roller 2 and the tube 1 moves and restores the original cross section. In this way, contained objects can be adequately conveyed.

In addition, it is provided with at least a circle Ia4 that rotates by the curvature 3. And the said chain A is
Since the tube 1 is hooked on the a--) 2 with an appropriate tension applied in its longitudinal direction, the inner circumferential wall of the tube 1 is crushed at the point where it contacts the roller 2), thereby causing it to contact the roller 2. The inside of the tube 1 is insulated across the points. Therefore, when the disk 4 is rotated, the contact point between the roller 2 and the tube 1 moves, and the contents in the tube 1, which is in front of the contact point in the tube 1 (g1) in the turning direction, are transported in the turning direction. It turns out.

A holder 5 is provided in the new nine, the gap between the holder 5 and the roller 2 is made smaller than the outer diameter of the tube 1, and the tube 1 is pressed by the p-22 against the circumferential wall of the holder 50. There are also other peristaltic pumps which compress the inner circumferential wall of the tube 1 and transport the contents within the tube 1 by 01ffi similar to the peristaltic pump shown in FIG.

タポンプを提供することを目的とするものである。Problems with the prior art In the peristaltic pump as described above, tubes 1 and 4-2
As the point of contact with tube 2 moves, the inner circumferential wall of tube 1 at the point that used to be the contact point must restore its shape and quickly become circular in cross section.However, in conventional peristaltic pumps, when the peristaltic pump stops, the tube 1 The inner circumferential wall of tube 1 was crushed, and since tube 1 is made of rubber, even when the peristaltic pump was driven, the inner circumferential wall of tube 1 did not recover quickly, and the inner circumferential walls of tube 1 stuck together. In order to prevent the inner circumferential walls of the 90-chape 1 from sticking to each other, which can result in improper conveyance of the contents, the composition of the rubber can be changed to increase the hardness of the rubber. (due to the loss of the elasticity of the rubber), this causes permanent deformation of the tube 1, and the performance of the peristaltic pump itself deteriorates. ) The crushing of the inner circumferential wall of the tube causes the contact point to shift.
The purpose of the present invention is to provide a peristaltic pump that can quickly recover from P1 and is suitable for transporting contents.

よい。Preferably, silicone rubber is used for the tube. Peristaltic pumps in automatic chemical analyzers for medical diagnosis suck and discharge various reagents, so silicone rubber has excellent chemical resistance. Examples of the oxidation treatment include peroxylic acid, hydrogen peroxide, peracetic acid, perbenzoic acid, potassium chromate, potassium dichromate, potassium permanganate, etc. During a method in which a silicon tube is immersed in a solution that dissolves an oxidizing agent for a certain period of time at a certain temperature, a peristaltic pump equipped with an unoxidized IDf: L-p is driven, and from the table, a solution is prepared in which the oxidizing agent is SS into the tube. An example of this method is to supply the liquid as a content for a certain period of time at a certain temperature. In short, any method may be used as long as it can oxidize the inner circumferential wall of the silicon tube.

い。The time required for oxidizing I/SO2 differs depending on the type of oxidizing agent, but usually 4 to 5 hours is sufficient. ・If the oxidizing agent has a high oxidizing power, the oxidizing treatment time may be shortened to reduce the saponifying power. For small oxidizing agents, it is necessary to lengthen the oxidation JK ring dark time. ◎When immersing a silicone tube in a 20-50-aqueous solution of perchloric acid, the oxidation treatment time should be O immersion time 4.
The temperature for zeroing treatment, which is preferably 11 degrees, varies depending on the type of oxidizing agent, oxidation time and waiting time, but usually,
Oxidation treatment at 20-60℃ is sufficient.In order to shorten the oxidation treatment time and increase treatment efficiency, oxidation treatment can be carried out at a high temperature. The temperature of the aqueous solution in which the tube is immersed may be room temperature.
