Abstract

PURPOSE:To perform MRI photographing as an intravenous drip treatment is safely effected without needing a man power by a method wherein the end part of a long cylindrical body is inclinably secured to a sleeping bed and gantry, and a hole through which a tube is inserted is formed in the end part in a longitudinal direction of the cylinder body or a suspension tool is mounted thereto. CONSTITUTION:A tube support tool has rigidity and flexibility and is formed with a long cylindrical body 1 capable of maintaining a bending state. The end part thereof is mounted to a bed seat 2 movable on a rail 25 of a sleeping bed top plate 24. The end part on the bed seat 2 side of the cylinder body 1 is inclinable by means of a pin 3, a hole 4 is formed in the vicinity of the end part on the bed seat 2 side of the cylinder body 1, and a cap 5 with a hole is mounted to an end part on the side opposite to the base seat 2. An intravenous injection blood tube 23 is inserted in the cylinder body 1 through the hole 4 and the hole of the cap 5 and is bent in a desired manner. This constitution causes the tube 23 to enter a gantry togetherwith a patient without exerting an impact force on the tube 23 in a state to hold the tube in a specified state. An openable ring 7 is mounted to the cap 5 with no hole, and the tube 23 may be inserted through the ring.

Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention is directed to magnetic resonance (MR)
rcs.

It is installed on the bed or gantry of an MRI machine to obtain morphological information such as slice images of a subject (living body) and functional information such as spectroscopy by taking advantage of the phenomenon of nancc). The present invention relates to a tube support for supporting.

(Prior art) Magnetic resonance is a phenomenon in which an atomic nucleus with non-zero spin and magnetic moment placed in a static magnetic field resonantly absorbs and emits only electromagnetic waves of a specific frequency. The angular frequency ω shown in Eq. (ωo=2πν., ν.;
A request that resonates at Larmor frequency).

ω0−γH.

Here, γ is the gyromagnetic ratio specific to the MLs of the atomic nucleus, and %HO is the static magnetic field strength.

This type of MRI apparatus, which performs biological diagnosis using the above-mentioned principle, processes electromagnetic waves of the same frequency as above, which are induced after the above-mentioned resonance absorption, to determine nuclear density, longitudinal relaxation time T.
+, t57 relaxation time T2. flow.

Diagnostic information that reflects information such as chemical shifts, such as slice images of a subject, is obtained non-invasively.

The collection of diagnostic information by magnetic resonance is performed using a static magnetic field 11.
Although it is possible to excite and collect signals from all parts of a subject placed in We are trying to collect the signals.

In this case, the specific region to be imaged is generally a slice region with a certain degree of sharpness, and the echo signal or magnetic resonance signal (MR (siri) signal) of the FID signal from this slice region is applied many times. These data groups are collected by performing the data encoding process of
For example, an image of the specific slice region is generated by performing image reconstruction processing using a two-dimensional Fourier transform method.

In such an MRI apparatus, 1. #j There are times when I perform intravenous drip treatment on patients (injured limbs) while taking pictures. In other words, the patient is on the tabletop that has been returned from inside the gantry to the initial position of the bed, and in this state, the doctor stands at the gantry entrance and removes the intravenous fluid container, cock (valve), and infusion fluid. A drip treatment device consisting of a tube, drip needle, etc. is set on the patient. First, a doctor or the like supports the infusion tube with one hand and uses the other hand to bring the needle close to a region such as the patient's wrist, and inserts the needle into the region. Then, the needle is fixed to the site using tape or the like so that the needle does not come off or move from the site.

Next, the patient is inserted into the gantry by the sliding movement of the large plate, but in this case, doctors must take care to prevent the infusion tube and needle from moving, applying force to the needle, and bending the infusion tube. Physicians and others move while supporting the infusion tube in accordance with the sliding movement of the top plate.

Once the patient is set in the predetermined imaging position within the gantry by the sliding movement of the top plate, the doctor, etc. must re-adjust the setting of the infusion tube, etc., to ensure that the infusion tube is not bent or crushed. That's what I do.

Then, shooting takes place. FIG. 8 is a diagram showing a situation in which a patient 21 lying on his back with an IV needle 20 inserted into his arm enters the gantry 22, and FIG. 9 shows a patient 21 who is looking down and having an IV needle 20 inserted into his arm.
FIG.
is an infusion tube, and 24 is a top plate.

Conventional MR1, which takes images while performing such intravenous treatment
The device has the following problems.

That is, it requires the help of a doctor or the like to support the infusion solution. In addition, since doctors and others cannot go inside the gantry, especially where the imaging takes place, there is a risk that infusion chub, etc. may get caught on the bed or blanket, and if it gets caught, they may not be able to enter the patient. The needle will move, which is dangerous. Furthermore, it is troublesome because the infusion tube and the like must be set again after the patient is placed in the gantry. Furthermore, in order to prevent infusion tubes and the like from becoming tangled, there is a problem in that the position where an intravenous drip can be injected must be specified.

In this way, with conventional technology, there is a risk that force will be applied to the infusion tube and needle as the patient enters the gantry, and even if this can be prevented manually, it is not perfect and is not only dangerous. This limited the areas where IV drips could be administered.

Therefore, the L1 object of the present invention is to make it possible to safely perform MR1 imaging while performing intravenous drip treatment without requiring human intervention, and to eliminate restrictions on the treatment area as much as possible. Our goal is to provide the following.
