Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a hyperbaric treatment tank equipped with an infusion cutoff device for accommodating a patient lying on a bed and administering oxygen treatment under hyperbaric pressure.

BACKGROUND ART Conventional hyperbaric treatment tanks have had a problem in that it is difficult to administer hyperbaric oxygen therapy to patients while safely infusing them with fluids.

This is because hyperbaric treatment tanks are generally sized to accommodate a patient lying on a bed, for example around 700 mm in diameter and 2000 mm in length, so they cannot be easily damaged due to natural falls. In many cases, infusions cannot be used due to head differences and difficulty in adjusting the amount of dripping, and infusions using an infusion pump (by bringing the infusion pump and pump drive control unit into the hyperbaric treatment tank) are This is because there is a high risk of causing a fire.

Therefore, the present inventor placed an infusion pump inside the chamber, and outside the chamber, placed a pump drive control unit equipped with a motor for rotating the infusion pump at a desired speed, a dose setting device, etc. We developed a single-person hyperbaric treatment tank in which the drive shaft of the infusion pump and the rotating shaft of the motor were connected through a drive transmission shaft penetrating the wall of the chamber, but this was because the infusion container was housed inside the chamber. , even in cases where it is necessary to urgently stop the supply of infusions due to a sudden change in the patient's condition during treatment, etc.
There was a problem in that it was not possible to immediately stop the supply of infusion from the outside.

Problems to be solved by this invention This invention solves the above-mentioned conventional problems, and when it is desired to stop the supply of infusions due to sudden changes in the patient's condition during treatment, it is possible to immediately connect the infusion tube from the outside. It is designed to be able to crush the infusion and stop the supply of infusion fluids in an emergency.

Means for Solving the Problem An infusion pump is arranged inside the chamber of a hyperbaric treatment tank, and a pump drive control is provided outside the chamber with a motor and a dose setting device for rotating the infusion pump at a desired speed. and connecting the rotation shaft of the infusion pump and the rotation shaft of the motor via a drive transmission shaft penetrating the wall of the chamber;
An emergency shutoff valve is provided inside the chamber between the infusion pump and the patient and crushes the infusion tube to stop infusion to the patient, and an emergency shutoff valve is provided outside the chamber to open and close the emergency shutoff valve. An operating body was provided.

Function: The infusion pump is installed inside the chamber, and the pump drive control section consisting of a pulse motor, pulse signal transmitter, etc. that drives the rotation of the infusion pump and controls the rotational speed is installed outside the chamber, which is different from conventional pumps. As in the case where the pump drive control unit is also incorporated inside the tank body, the pump drive control unit,
In particular, the inside of the tank will not burn up due to sparks or overheating generated by the pulse motor, and in an emergency, the emergency shutoff valve will immediately stop infusion to the patient and safely perform hyperbaric oxygen therapy, etc. be able to.
