Description

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

BACKGROUND OF THE INVENTION Conventional single-person 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 it is difficult to use an infusion container. In many cases, infusions that are brought into the chamber and allowed to fall naturally cannot be used because of the difference in head and difficulty in adjusting the amount of dripping. This is because transfusion (brought into the tank) has a high risk of causing a fire.

Therefore, the present inventor placed an infusion pump inside a chamber, and placed a pump drive control section outside the chamber, which includes a motor that drives the infusion pump to rotate at a desired speed, a dose setting device, etc. 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 via a drive transmission shaft penetrating the wall of the chamber, but this tank housed the infusion container inside the chamber. Therefore, when a patient's condition suddenly changes during treatment, it is not possible to immediately add the appropriate drug to the infusion container or replace the infusion container with another one. It was hot.

Problems to be solved by the invention This invention solves the above-mentioned conventional problems, and when the condition of a patient undergoing treatment suddenly changes, it can immediately add the appropriate drug to the infusion container, or The purpose of this invention is to provide a single-person hyperbaric treatment tank in which the infusion container can be replaced with another infusion container.

Means for Solving the Problems: An infusion pump is arranged inside the chamber of a single-person hyperbaric treatment tank, and a pump is equipped with a motor and a dose setting device outside the chamber for rotating the infusion pump at a desired speed. A drive control unit is arranged, and the drive shaft of the infusion pump and the rotating shaft of the motor are connected via a drive transmission shaft penetrating the wall of the chamber, while the infusion container or tube is connected to the wall of the chamber. A hatch was provided to guide it to the outside.

Function: The infusion pump is installed inside the chamber, and the pump drive control section, which consists of a motor, pulse signal transmitter, etc. that drives the rotation of the infusion pump and controls the rotation speed, is installed outside the chamber. Unlike in the case where the drive control unit was also built into the tank body, there is no possibility that the pump drive control unit, especially the pulse motor, would ignite a fire inside the tank due to sparks or overheating. In addition, by leading the infusion container out of the chamber through a hatch provided on the wall of the chamber, even if the patient's condition suddenly changes, the infusion container can be immediately replaced with an infusion container for another drug. This enables immediate response to sudden changes in a patient's condition.

The notch grooves 8h of the packing suppressing plate 8i are formed at eccentric positions so as not to overlap with each other, ensuring a sealing effect between the lid body 8f, the seal packing 8m, and the packing suppressing plate 8i. .

Since the single-person hyperbaric treatment tank equipped with the infusion hatch of the embodiment has the above-mentioned configuration, the patient undergoing infusion is accommodated in the chamber 2 while the patient is receiving infusion, and the arcuate outer wall 12 is By operating the infusion tube 9 between the outer wall 12 and the rotors 5a and 5b.
At the same time, place the infusion container 10 into the tank body 3.
Lead out from the hatch 8 provided on the wall of
It is supported on a stand S erected outside the tank body 3. Then, after setting the dose using the dose setting device 6c of the pump drive control unit 6, if the pulse motor 6a is driven, the pulse motor 6a rotates at a constant speed, and the rotation of the pulse motor 6a is driven. Transmitted to the infusion pump 5 via the transmission shaft 7, the rotors 5a and 5b rotate at a constant speed, crushing the infusion tube 9 between the arcuate outer wall 12 and sending a certain amount of infusion into the patient's body. It is.

FIG. 11 shows a case where a so-called plunger type pump is used as an infusion pump. The infusion pump 5 is not limited to what is illustrated.

Effects of the Invention As explained above, the present invention has an infusion pump disposed inside a chamber, and a pump equipped with a motor, a dose setting device, etc. for rotating the infusion pump at a desired speed outside the chamber. A drive control unit is arranged to connect the drive shaft of the infusion pump and the rotating shaft of the motor via a drive transmission shaft penetrating the wall of the chamber. Since this is a single person hyperbaric treatment tank equipped with a hatch for infusion, which is characterized by having a hatch for leading the fluid to the outside, it has the following effects.

(1) The pump drive control unit such as the motor is placed outside the chamber, and unlike conventional pump drive control units that were built inside the chamber, sparks or overheating of the motor could cause the chamber to There is no longer any chance of a fire igniting inside, and hyperbaric oxygen therapy can be performed safely.

(2) The infusion container can be led out of the chamber via the hatch, so even if the patient's condition suddenly changes, you can immediately add the appropriate drug to the infusion container, Alternatively, by replacing the infusion container with an infusion container for another drug, sudden changes in the patient's condition can be dealt with immediately, making it possible to perform hyperbaric oxygen therapy and the like more safely.

It goes without saying that when the infusion solution runs out, it can be replaced with a new infusion container.
