Definitions

  • a tube formed in a loop in a housing is crushed by a roller with a rotationally-aligned roller into a stubborn-type tube bonder.
  • tube pumps using silicon, PVC or the like are widely used for medical purposes.
  • the rotation speed is too low to use small diameter tubes. It is better to use a small tube with a diameter of 2 mm or less so that the liquid and the air do not pass each other in the tube even when the pressure is increased, so that the liquid does not remain.
  • ⁇ Practical flow of 200 to 300 cc per nail 2 ! It takes 600-1200 revolutions per minute to get, which is twice as fast as conventional ones to more than 10 times.
  • the gap between the roller and the inner circle must be reduced, but this will cause the tube to shift in the direction of travel or to the side: protrude.
  • Increasing the number of revolutions also caused the tubes to slip in the rolling direction, slip out of the mouth, and the rollers to double-fold the tubes in the freely movable space inside the housing. To prevent this, it was effective to provide a lecture guide to some extent, but it made the replacement of tubes extremely difficult. This was the third disadvantage.
  • a conventional tube pump is improved as follows.
  • FIG. 1 is a front view of an embodiment of the present invention
  • FIG. 2 is a top view of FIG.
  • FIG. 3 is a sectional view taken along the line It of FIG. 1

  • FIG. 1 FIG. 2 FIG. 3 is a drawing showing one embodiment of the present invention, in which a rotating circle is fixed to a motor shaft or other rotating shaft 1.
  • FIG. The roller 3 is fixed to the rotating disk 2 by the core rod 4, but the roller 3 revolves with the rotating circle ⁇ ⁇ ⁇ ⁇ 2, and the core rod 4 is rotated around the center when the tube is squeezed. .

  • the housing 5 has an inner circle 6 inside which is a concentric circle centered on the rotation axis 1 and an outer side which is fixed in a square, cylindrical or other shape.
  • the housing 5 is provided with an entrance / exit hole 8 for the tube 7 as a groove in this example.
  • the proper length is measured, and a tube 7 serving as a convex portion 9 is attached to the roller 3 by attaching, for example, a coupling or the like to both ends, and the tube 7 is fixed by the receiver 10 to maintain the tension constant.
  • the tube length required for the protrusion 9 is 17 cm.
  • the material which has been shortened by 2 cm to 15 cm is extended and wrapped around the roller 3, and the gap 11 between the roller 3 and the housing 5 is formed according to the required pressure. adjust.
  • Fig. 5 shows another example of a method for maintaining the tube tension. This is the case where a long tube 12 is used without using a coupling.
  • the marks 13 are placed at both ends corresponding to the entrance and exit in the middle of the tube 5 and fixed there with a tool 14 ⁇ Tubes with an outer diameter of 5 mm cannot be loosened with this degree of tension when tightened with a 4.5 mm diameter hole fitting 14. However, if the tube is pulled with a little force, it will move, and if the length of the tube deviates by as much as 5 mm, pressure shortage or tube disengagement will occur immediately, so that the mark can always indicate the correct position to 1 3 is inevitably required.
  • a protrusion may be provided at both ends of the corresponding section in the middle by bonding small pieces of the same material as the tube.
  • the retainer such as a mark or a protrusion, attached to the tube, and the fastener provided at or near the entrance / exit hole of the housing.
  • Fig. 4 is a view before setting the tube of Fig. 3, but if the inner circle 6 is cut in this way to widen the gap at the edge, 20 or roller 3 will be connected to the housing 5.
  • the tube 7 protrude slightly to make it easier to hang on the roller 3, the first time the tube is hanged, as shown in Fig.
  • the tube 7 is wound around the gap surface 11 between the roller 3 and the inner circle 6, and automatically snaps into an appropriate position as shown in FIG. Of course, there is no slipping or entanglement during rotation 25 .
  • the most important issue with the tube entrance is the angle between the hole and the inner circle of the housing.
  • the conventional pump is installed inside the housing. Entrance and exit holes are provided to circumscribe the circle.
  • the pump of the present invention has no practical use because it has one hole toward the center of the inner circle or two outlets and inlets parallel as shown in FIGS. The reason for this is that the tube for the tube pump originally has a material and a wall thickness with a strong restoring force, and further requires a certain wall thickness more than usual because it is used by being pulled further for use in the present invention.
  • the strong restoring force does not cause the wall of the entrance to be severely bent at an angle, and the tension is applied so that the tube does not escape.
  • the corner may be rounded or an entrance hole may be provided so as to circumscribe the circle of the housing.
  • the entrance hole 8 is carved from the surface of the housing 5, it is good for replacing the tube 7 with ease.
  • the entrance hole can be made quite freely, but the roller should be made as long as possible, and the holes should be made as smooth as possible.
  • the rotation speed of the Boner has been increased, allowing the use of smaller diameter tubes. No liquid remained in the tube, and a practical flow rate was secured.
  • the tube does not come off or jam without the guide. Therefore, the tube can be easily attached to the crotch, and the tube can be simply replaced. Also, since the roller and housing do not need to be moved, the structure is ⁇ ⁇ and the accuracy does not change.
  • the housing may have any shape, the inner circle only needs to be a perfect circle, and the entrance and exit holes of the tube are simple, so it is extremely easy to manufacture according to the transferred object, tube, pressure, etc. is there.
  • the pressure in the Boner can be controlled to some extent. This makes it possible to adjust the discharge pressure of the pump to a pressure that does not break blood cells or that is required by the contents during use.
  • the dispensing can be performed while the patient is in the middle, the preparation of both the S filter and the dispenser has made it very easy to use a small amount of self-formulation, which had to be cleaned up.
  • it can be used for medical purposes, such as blood suction during surgery and difficulties, just by changing tubes for each person without infection, etc., but it can also be used in general industries other than medical use Also used as a high-performance tube pump in Japan.

Abstract

Pompe péristaltique du type dans lequel un tube formant une boucle est comprimé par des rouleaux rotatifs dans un logement. Les améliorations apportées par la présente invention à une pompe de ce type consistent en ce qu'un tube flexible présentant une paroi de forte épaisseur pour son diamètre interne est étiré jusqu'à une longueur suffisante et passé autour de rouleaux, de sorte qu'une force de traction appropriée s'applique sur le tube, de manière à atteindre une vitesse d'écoulement et une pression de fluide beaucoup plus élevées qu'avec une pompe traditionnelle du même type. Cet agencement permet un remplacement très facile du tube, ce qui accroît la gamme d'utilisations de ladite pompe.
